Patent number: 11181442Abstract: A six-DOF motion testing and motion parameter decoupling method for rotors based on shaft-disk is proposed, which includes a displacement sensor tooling and a precision shaft-disk fixed on the rotor where three measuring points are arranged on the surface of disk to measure the axial motion of the rotor, two measuring points on the shaft to measure the radial motion, and the angle encoder at the shaft shoulder to measure the rotation motion. The tooling guarantees the accuracy of displacement sensors. The fixed coordinate system and the shaft-disk moving coordinate system are set, and the measured values of the displacement sensors and the encoder are represented by vectors to establish the relationship between the six-DOF motion of the shaft-disk axis and the measured values of sensors. Thus, the six-DOF motion of the rotor/shaft-disk can be determined by the measured data.Type: GrantFiled: April 18, 2019Date of Patent: November 23, 2021Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Huimin Dong, Chu Zhang, Delun Wang, Jun Qiu, Zhi Wang

Patent number: 5219265Abstract: In the installation of underground utilities it is common to utilize an earthmoving machine, such as hydraulic excavator, to dig a trench and aid in the placement of the individual pipe segments that comprise a conduit or pipeline. Normal placement of the pipe segments requires communication between the excavator operator and laborer that is positioned adjacent the pipeline in the trench. As the pipe segments are lowered into position, the laborer insures a proper connection of each joint and the overall support beneath the pipeline. The requirement of another individual in the trench is both inefficient and represents a significant increase in the cost of laying the pipeline. The present invention utilizes a grapple assembly to grasp the individual pipe segments to maneuver them into and within the trench. The grip on the pipe segment is sufficient to permit its insertion into the unfinished pipeline.Type: GrantFiled: January 13, 1992Date of Patent: June 15, 1993Assignee: Caterpillar Inc.Inventor: Roger L.

Patent number: 4221525Abstract: An apparatus (10) is used for transporting one or more elongated members (12), such as logs (12) or pipes. The absence of developed roadways into tree cutting sites, for example, requires an apparatus (10) for transporting logs (12) over difficult terrain from the site to other locations. In the apparatus (10) for transporting the elongated member (12), first apparatus (20) controllably engages a first end portion (14) of the elongated member (12) in supporting relationship in response to being urged between the first end portion (14) and the ground (32) in a direction (34) generally longitudinal relative to the elongated member (12). Second apparatus (26) controllably engages a second end portion (16) of the elongated member (12) and maintains the first end portion (14) in supporting relationship with the first apparatus (20).Type: GrantFiled: August 28, 1978Date of Patent: September 9, 1980Assignee: Caterpillar Tractor Co.Inventor: Robert N. Stedman

Patent number: 4210183Abstract: Conventional linkage projecting forward from a tractor, such as the linkage commonly used to support the bucket of a loader, carries a box frame for elevational movement and for tilting of the frame about a horizontal axis. Two sets of clamping grapple arms are mounted on cross members of the frame by upright pivot shafts extending between such cross members for swinging of the grapple arms. Jaws including shearing blades are mounted below the grapple arms between cross members of the frame for swinging about axes registered with the grapple arm axes. With the frame upright and the grapple arms and jaws open, the tractor is driven forward to embrace a standing tree between the grapple arms and the jaws. The grapple arms are closed to clamp the tree followed by closing the jaws to shear the tree, whereupon the tree, standing on the shearing blades, can be maneuvered in upright position to a piling or yarding area and swung downward by tilting the box frame forward.Type: GrantFiled: November 20, 1978Date of Patent: July 1, 1980Inventor: Christopher Nilsen

Patent number: 4189269Abstract: A workpiece transport device which includes at least one gripper tong arrangement driven in comformity with a work rhythm of a machine tool which is required to be charged and/or discharged. The gripper tong arrangement grips a marginal area of the workpiece, transports the workpiece, and deposits the workpiece at another machine tool or workpiece depository. An extensible and retractable support slide is provided for supporting the workpiece in a transport phase by being displaced beneath the workpiece in parallel to the gripper tong arrangement.Type: GrantFiled: April 27, 1978Date of Patent: February 19, 1980Assignee: L. Schuler GmbHInventors: Karl Maier, Herbert Hohn

Patent number: 4148399Abstract: The invention relates to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms slidably mounted on the beam. The arms have bale penetrating members rotatably mounted or fixed thereon. First power actuated means operably pivot said beam in an arc about the rear end of the pickup toward and away from the ground. Second power actuated means slide the arms and penetrating members along said beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and away from each other to release the bale. The bale penetrating members are rotatably or fixedly mounted on the arms to allow a bale to be unrolled to facilitate feeding the hay of the bale to animals.Type: GrantFiled: December 20, 1976Date of Patent: April 10, 1979Inventors: Jackie L. Carter, Jerry D. Carter
