DETAILED DESCRIPTION

As shown in FIGS. 1-2, modular pipe basket 100 includes base 101, stanchions 102, and end caps 103. Base 101 has two ends and is rectangular. Base 101 includes longitudinal members 104, cross members 105, and support members 106. Cross members 105 are welded to longitudinal members 104 and are substantially perpendicular to longitudinal members 104. In an embodiment, support members 106 bridge between longitudinal members 104 and cross members 105 diagonally (i.e., at angles which are not right angles) so as to provide the maximum strength and rigidity to base 101.

In the embodiment depicted in FIG. 2, base 101 includes only two longitudinal members 104, but those skilled in the art may wish to include two or more longitudinal members 104. Similarly, while the figures show the use of five pairs of cross members 105 (three pairs in the midsection and one pair at each cap), those skilled in the art may wish to employ a different number of cross members 105 so long as cross members will support the pipe held in basket 100. For weight savings, longitudinal members 104, cross members 105, and support members 106 are rigid round or square tubing or rigid beams which are joined together either by welding or other fastening means. Those skilled in the art could construct base 101 in other configurations, such as using a solid sheet of steel.

In an embodiment, basket 100 will include at least two (one on each side) stanchions 102. Stanchions 102 project upwards from longitudinal members 104 wherein stanchion 102 is in a plane that is substantially perpendicular to said base. Stanchion 102 can be made of square or round tubing, beam material, or other equivalent structure. For maximum strength, each connection between stanchion 102 and longitudinal member 104 is reinforced with stanchion support 107. Stanchion supports 107 are cut in a roughly triangular shape and then welded to stanchion 102 and longitudinal member 104. It would be obvious to one skilled in the art to use another method of bracing stanchion 102, such as using a metal beam or other like structure. In another embodiment, footings 109 are placed at the bottom of the base 101 in spaced pairs so as to create recesses 108 between each pair of footings 109. Recess 108 formed by a pair of footings 109 allow the top of each stanchion 102 on bottom pipe basket 100 to fit into recess 108 when stacking basket 100. Footing 109 may or may not extend across the entire width of the base. Footing 109 will also elevate basket 100 from ground level so as to provide a space underneath base 101 for forklift forks to slide under basket 100 for lifting of basket 100. It would be obvious to one skilled in the art to use a means for receiving forklift forks without footing 109 by creating at least one aperture in the side of base 101 for receiving forklift forks.

Basket 100 will also include two end caps 103. Each end cap 103 provides a means to stop and prevent the pipe from sliding out of either end of basket 100. For example, if basket 100 were being carried on a typical flatbed truck trailer and the truck had to make a sudden stop; end cap 103 would prevent the pipe from sliding forward and endangering the truck driver. In addition, the end cap will have the ability to prevent damage to the ends of the pipes when transporting and storing the pipe in pipe basket 100. End cap 103 should be constructed of steel plate, corrugated metal, expanded metal, or any material or design that will perform the desired function of arresting the sliding movement of the drill pipe.

In another embodiment, basket 100 will include at least one bin 110 which will have integrated therein an end cap 103 to stop the pipe from sliding, as shown in FIG. 3. Bin supports 123 can be used to add strength and rigidity to the connection between bin 110 and longitudinal members 104. Alternatively, in the absence of bin 110, the bin supports 123 can be joined directly to the end cap 103 to add strength and rigidity to end cap 103. Additionally, bin 110 will provide storage space on pipe basket 100 and shall comprise end wall 114, two side walls 112, a front wall 113 and a bottom 111. The end cap 103 may serve as end wall 114 for the bin, but those skilled in the art may wish to introduce end cap 103 independently from bin 110. Furthermore, those skilled in the art may wish to locate end cap 103 between bin 110 and pipe loading area 126. Typically, drill pipe is already threaded and thread protectors will be on the threaded sections of the drill pipe when the pipe is shipped. Although the bins can be used for various items, it is contemplated by the inventors that bin 110 will provide a convenient container for storage of the thread protectors and wood strips. Having bin 110 on basket 100 provides a way for the pipe purchaser to return the thread protectors, along with the basket, to the pipe seller.

Bin 110 will include bin bottom 111, which can be made of steel grate or expanded metal so as not to collect water. Bin 110 will also include side walls 112, front wall 113, and end wall 114. Bin 110 may also include lid 115. For added strength, bin 110 can be made by integrating beams into side walls 112, front wall 113, end wall 114, or bin bottom 111. In addition, any of the bin walls can be reinforced by a ridge which can be created by bending the plate steel used to fabricate the walls. Bin 110 can also include lid 115. In another embodiment, at least one bin wall shall be constructed of corrugated metal so as to provide increased strength and reduction of weight of pipe basket 100. To provide maximum strength to bin 110 and basket 100, side walls 112, front wall 113, and end wall 114 can be made from one piece of sheet steel which is bent at right angles to form bin 110. Also, square or round tubing or beam material can be used to add support to bin 110 by providing a rigid frame for bin 110.

To assist personnel in accessing the top of basket 100 and the inside of bin 110, bin 110 can also include an integrated ladder 117 as shown in FIG. 4. The ladder 117 may be recessed into the end cap 103 so as not to protrude from the pipe basket 100. In addition, the ladder can be installed on each end cap 103, provided that the ladder 117 is incorporated on alternate sides from the ladder on the opposing end. This will allow ladder 117 on bottom basket to always line up with ladder 117 on the top basket in the event the baskets are stacked on top of each other. In addition, ladder hand support 124 can be installed to provide a hand grip for personnel climbing ladder 117.

As shown in FIG. 1, one or more load securing points 118 can be placed along pipe basket 100. Load securing point 118 may be located within stanchion support 107 as shown in FIGS. 5A and 5B. Load securing point 118 may be provided in at least four points along the base 101, two along each alternate side of the pipe basket 100. At least one load securing means 119 can be placed on one side of pipe basket 101 at load securing point 118 wherein load securing means may be a ratcheting apparatus or equivalent fastening means as shown in FIG. 5A. Although load securing means 119 is shown in an upright position in FIGS. 1, 5A and 6, a slight modification to the load securing point 118 can be made so that the load securing means 119 can be inverted, thereby positioning the load securing means 119 upside down within load securing point 118. At least one strap receiver 127 will be placed on the opposite side from load securing means 119 to provide a connection for strap 125 as shown in FIG. 5B. The strap receiver 127 can be a hook, grapple, clasp, catch, or other equivalent securing means. Strap 125 will be used to hold the drill pipe securely in place during transport wherein such strap 125 can comprise a cloth, metal or polymer strap, chain, cable or other like tie down means. In the stacked configuration shown in FIG. 6, one or more of the straps from the bottom basket 100 may be wrapped around the longitudinal members 104 or any part of the top basket 100 so as to secure the two baskets together during transport or storage.

To assist in safely lifting the pipe basket 100 with the use of a crane or other like lifting means, sling lifting brackets 121 which can be incorporated into the pipe basket 100 as shown in FIGS. 5A and 5B may be used. Sling lifting brackets 121 are rigid members that may project diagonally (i.e., at angles which are not right angles) from longitudinal members 104 and are located at four different points along the pipe basket 100. However, the sling lifting brackets 121 can also project perpendicular or parallel from longitudinal members 104. Also shown in FIGS. 5A and 5B, sling lifting bracket 121 contains pad eye 119 which is an aperture placed in sling lifting bracket 121 so as to allow a connection point for the lifting slings of a crane or other like lifting device. Ideally, pad eyes are drilled, not cut, so as to provide superior strength for pad eyes 119 which are used as lift points. It would be obvious to one skilled in the art that pad eye 119 can also be a separate device that is joined to pipe basket 100. To lift basket 100, one may connect a sling to pad eye 119. The sling lifting brackets 121 are added to provide additional lifting support. It will be obvious to those skilled in the art that pad eyes could be placed at several points on basket 100, including but not limited to stanchion 102, stanchion support 107 and base 101. In addition, stanchion support 107 could serve as sling lifting bracket 121.

In another embodiment, the material for all the components of the pipe basket 100 will be galvanized carbon steel to help reduce corrosion of pipe basket 100. In another embodiment, longitudinal member 104 would be made of 10-inch thick beams to allow for adequate support of pipe basket 100.

By way of example only, pipe basket 100 could have a total length of 38 feet with a usable interior space that can accommodate pipe of up to 34 feet in length. Basket 100 can be made with a width of approximately four feet and a height of about 54 inches. With these dimensions, two baskets 100 can be placed side by side on a conventional truck trailer.

In operation, basket 100 is loaded with drill pipe. Once basket 100 is loaded with the desired quantity of pipe, strap 125 can be tightened over the pipe using strap load securing points 118. As shown in FIG. 6, a first pipe basket 100 can be stacked on top of a second pipe basket 100. The two baskets can be secured together using the straps 125 and load securing means 119 or equivalent securing means. As the pipe loaded therein is used, any thread protectors on the pipe and wood stripping used to space the pipes can be placed in bin 110.

Another embodiment of the basket includes removable backstops 200 instead of fixed end caps 103. The location of backstop 200 is adjustable to accommodate different size pipe. It is desirable to minimize the gap between the end of the pipe and the back side of backstop 200 to minimize the impact associated with shifting pipe during sudden stops. In an embodiment of the invention the pipe basket is arranged and configured for the carrying of range 2 pipe. In that embodiment, the distance between the backstops is the length of the range 2 pipe being carried plus an allowance distance. As an example, the allowance distance may be a distance that is sufficient to allow loading of pipes in the basket without substantial endurance by a basket end. As a further example, the allowance distance may be small enough to contain the pipe being carried in the event of a sudden change in momentum of the basket. In a related example the allowance is less than 1 foot. In a further related example, the allowance is less than 2 feet and in a still further related example, the allowance is less than 3 feet. In a related example, the allowance is greater than 6 inches. In a further related example, the allowance is greater than 8 inches and in a still further related example, the allowance is greater than 10 inches. In a further related embodiment, the distance between the backstops is the length of the range 3 pipe being carried plus an allowance distance. The allowance distance for this embodiment may be any of the allowance distances disclosed for range 2 pipe. In a further related embodiment, basket 100 is used without backstops 200 or other restrictions at the ends of basket 100 to accommodate various lengths of pipe such as range 3 pipe.

Referring now to FIGS. 7A and 7B of the drawings, the end may be a removable end. Backstop 200 may be fastened to both longitudinal members 104 using a system of slots and pins contained within an attachment assembly 213. The attachment assembly 213 contains one or more J slots 210 and an equal number of rear alignment locator pin slots 211 and holes 212 to allow penetration of locking clevis pins 203. Backstop 200 includes a real alignment locator pin 201, a forward location pin 202 and holes 204 to allow for the penetration of locking clevis pins 203. To attach backstop 200, forward location pin 202 is inserted into J slot 210. As shown in the embodiment depicted in FIGS. 7A and 7B, the choice of J slots determines the effective length of the basket. Backstop 200 is secured to each longitudinal member 104 by insertion of rear locator pin 201 in rear alignment pin slot rear alignment locator pin slots 211. Lifting of backstop 200 may be accomplished with the aid of a sling (not shown) attached to lift point 206. After backstop 200 is in place, i.e., forward location pin 202 is securely inserted into J slot 202 and rear alignment pin 201 is inserted into rear alignment pin slot 211. The backstop may be further secured by insertion of locking clevis pins 203 through appropriately placed holes in the attachment assembly 213 and the holes 204 on the sides of backstop 200. Those skilled in the art may substitute an alternate means to pin or secure the backstop 200 to the attachment assembly 213.

FIGS. 7A and 7B further show the placement of the channel iron 220 which is adjacent to and attached to stanchion 102. Stanchion 102 and channel iron 220 project upwards from longitudinal member 104, wherein both stanchion 102 and channel iron 220 are in a plane that is substantially perpendicular to longitudinal member 104. Stanchion 102 and channel iron 220 may be reinforced with one or two station supports 107. Retainer bracket 223 freely slides within channel iron 220. Within retainer bracket 223 is an arched rubber strip 225 (not shown) which is designed to contact the uppermost pipe loaded in the basket. The arch is designed to correspond to the arch of arched board 222. Stanchion 102 and channel iron 220 act as physical barriers to constrain and contain pipe that is placed within the basket. Further, channel iron 220, retainer bracket 223, arched board 222, and load securing point 118 cooperate to secure pipe within the basket when the basket 100 is loaded according to a method described below. Footings 109 support the basket and recess 108 that is opposite stanchion 102 may be used in the stacking of other similar pipe baskets. Tagline D ring 208 allows control of the basket during maneuvering such as when the basket is lifted by a crane.

Referring now to FIG. 8 of the drawings, attachment assembly 213 is attached to the upper face of longitudinal member 104 and contains J slots 210, rear alignment locator pin slots 211, and holes 212. The strap from ratchet strap 125 is designed to travel to the interior of retainer bracket 223 over arched rubber strip 225 (not shown) which sit atop the load of pipe and down to load securing point 118. The tensioning of the strap from ratchet strap 125 secures the load in place. Also shown in FIG. 8, stanchion member 102 extends directly up, being perpendicular to longitudinal member 104. A board 222, or other supportive material such as rubber, extends between the two longitudinal members 104 creating an arched support bed on which the pipe or similar cargo may lay. Boards equivalent to board 222 are spaced along the length of basket 100 such that the cargo is similarly supported along the length of basket 100. Not shown in this view, directly beneath board 222 is a cross member 105. Channel irons 220, also shown in FIG. 8, extend directly up, being perpendicular to longitudinal member 104 and adjacent to the stanchion member 102. Together, the channel irons 220 and stanchion 102 form the side of the basket, holding the pipe within. After the pipe has been otherwise secured, the retainer bracket 223 is bolted to the open side of the channel iron 220, for additional security.

As shown in FIG. 9, a cross member 105 is welded to longitudinal members 104 at the location of the stanchion 102 and is perpendicular to both longitudinal members 104 and stanchion 102. Board 222, or other slightly flexible but supportive material, is placed on the top side of the cross member to support the pipe carried within. Board 222 may be arched in any manner that allows for the arching of pipe layers such that the tensioned strap from ratchet strap 125 exerts force on each of the pipes in the basket by way of exerting downward force on arched rubber strip 225. This downward force sandwiches each layer of pipe between arched rubber strip 225 and arched board 222 with flexible pipe separators 224 separating each layer of pipe. Pipe is laid within the basket, lying both perpendicular to the cross member 105 and perpendicular to stanchions 102. The cross member 105 and the arched board lay within the same plane. Multiple layers of pipe are laid in the basket, separated by flexible pipe separators 224. Material to be used for pipe separators must be flexible yet able to support and cushion the load of pipe. Flexible pipe separators may be secured between the two pieces of channel iron 222. In one embodiment, pipe separators 224 are made of rubber strips having dimensions similar to framing lumber boards. Actual lumber or other supportive and moderately flexible materials can be used in the place of rubber. Pipe separators 224 lie parallel to cross member 105 and arched board 222, however in a different vertical plane.

As shown in FIG. 9, the top layer of pipe is secured by a final layer of modestly flexible stripping 225 that is tied down with straps from ratchet strap 125 with the assistance of load securing point 118. The arched rubber strip 225 may alternatively be wood or another material of comparable properties. Ratchet strap 125 is utilized to place tension on the strap from ratchet strap 125 by passing the strap over the arched rubber strip 225, securing it to load securing point 118 and ratcheting the ratchet component of ratchet strap 125. After the rubber stripping 225 is secured in place with flexible straps under tension, the retainer bracket 223 is fastened to the channel iron 220 to secure and support the rubber stripping and flexible strip. Retainer bracket 223 is comprised of two horizontal members, each parallel to the ends of the basket and perpendicular to the channel iron 220, that straddle arched rubber stripping 225, holding it in place.

FIG. 10 is a full side view of the embodiment utilizing the removable backstop 200.

Installation of backstop 200 occurs by lowering the backstop 200 toward the base. Specifically, the forward location pin 202 is inserted into the desired J slots 210. The choice of J slots 210 is based on the desired length of the completed basket, which in turn is based on the length of pipe being transported. Once forward locator pins 202 are secured in J slots 210, backstop 200 is lowered so that rear alignment locator pin 201 slides into rear alignment locator pin slots 211. When backstop 200 rests securely on attachment assembly 213 and longitudinal members 104, locking clevis pins 203 are inserted into holes 204.

Pipe may optionally be loaded onto basket 100 by a pipe deck machine. Interaction with a pipe deck machine is accomplished by removing the backstop 200 that is nearest the pipe deck machine and allowing the pipe deck machine to lower a section of pipe into basket 100. Lifting and lowering of pipe by the pipe deck machine is accomplished by clamping onto a pipe at multiple locations with the arm of the pipe deck machine and raising the pipe out of the basket, rotating that pipe to a vertical position adjacent the basket.

Loading of pipe onto the basket may be accomplished by laying a single layer of pipe in between stanchions 102 on the several similar arched boards 222 by any one of various means, including forklift, crane, or pipe deck machine. Next, a pipe separator 224 is laid over the first layer of pipe within channel iron 220. Multiple layers of pipe and pipe separators 224 are laid in the basket to field the basket cargo area. Each layer of pipe separators 224 is laid in a similar fashion at each end of pipe basket 100. Retainer bracket 223 is then slid into channel iron 220 and secured to channel iron 220 immediately above the top layer of pipe with locking screws. The strap of ratchet strap 125 is then looped over arched rubber strip 225, attached to load securing point 118, and ratcheted to a tension sufficient to secure the pipe against movement during transport. Multiple ratchet straps 125 and securing points 118 are placed along the length of basket 100 on longitudinal members 104, such that the pipes are secured within basket 100. In one embodiment, ratchet straps 125 are placed along the longitudinal members 104, alternating between longitudinal members 104 such that the tensioning of the straps of ratchet straps 125 pulls on the cargo in alternating directions.

In one embodiment of the backstop, the weight balance is such that the forward loading pin 202 is lower than the rear alignment pin 201 and comes in contact with the J slot 210 prior to the rear alignment pin 201 making contact with the rear alignment locator pin 211. After the forward location pin 202 is securely resting in the desired J slot 210, the process of lowering the backstop 200 is continued until the rear alignment locator pin 201 rests within the rear alignment locator pin slot 211. The backstop 200 is secured to the base by use of pins 203, which are readily inserted to secure the backstop to the base and readily removed to disassemble. Removal of the backstop occurs by reversing the steps above.

In an embodiment of the invention, basket 100 is 33 feet or 35 feet in length with the backstops 200 installed at the two alternate positions. For example, the basket 100 may be 30 feet long without the backstops 200 installed. For example, basket 100 may be 4 feet wide and 4 feet 8 inches tall. As a further example, the cargo area may be 32 feet long or 34 feet long depending on the positioning of backstops 200. As a further example, the cargo area may be 40 inches wide and 36 inches high. In one embodiment, basket 100 with backstops 200 installed weighs 4450 pounds. In a related embodiment, basket 100 has the capacity to handle 17,550 pounds of pipe.

As used herein, the term “load rating” indicates the maximum amount of weight that a structural member can sustain at its center when supported at both ends.

It is understood that the array of features and embodiments taught herein may be combined and rearranged in a large number of additional combinations not directly disclosed, as will be apparent to one having skill in the art. There are, of course, other alternate embodiments which are obvious from the foregoing descriptions of the invention, which are intended to be included within the scope of the invention, as defined by the following claims.
