  • Patent number: 5599140
    Abstract: A reinforcing and support system and method of installation thereof including both a mechanical expansion anchor on the distal end of an elongated bolt and a resin grouting mix installed in a blind drill hole in a mine roof, or the like. A pair of elongated leg members, fixed with respect to the shell, extend into the annular space surrounding the bolt below the shell for a distance about as great as the axial length of the shell. Upon advance of the bolt, carrying the expansion anchor and leg members, into the drill hole to break a cartridge containing the initially flowable components of the grouting material, the bolt is rotated to effect expansion of the anchor and tensioning of the bolt. Mixing of the components in the annular space surrounding the bolt below the anchor as the bolt is rotated is enhanced by hydraulic turbulence produced by flow of the components about the leg members.

  • Patent number: 5098227
    Abstract: An otherwise conventional mine roof expansion anchor of the bail-type is provided with a tubular retainer member encircling the shell leaves and having an external cross-dimension significantly (e.g., at least 0.10") greater than the diameter of the drill hole in which the anchor is to be installed. Thus, as the anchor, supported on the end of a roof bolt, is advanced into the drill hole in the usual manner, the tubular element is pushed off the anchor by contact with the surface surrounding the drill hole, thereby eliminating the previously required manual removal of the retainer. The tubular retainer has the same cross-sectional configuration in all planes perpendicular to its central axis throughout its full length, preferably being formed as a plastic extrusion.

  • Patent number: 5064311
    Abstract: An assembly and methods of installation thereof for supporting and stabilizing a rock structure adjacent a mine tunnel or other underground passageway. The assembly includes an elongated bolt, threaded from both ends for at least a portion of its length. A conventional, mechanical expansion anchor is threaded on one end of the bolt, within a drill hole in the rock structure, and a bearing plate, washer, jam nut and tensioning nut are carried on the other end, outside the drill hole. The tensioning nut is threaded into firm engagement with the jam nut to prevent further threaded advance of the tensioning nut a substantial distance from the termination of the threads. A torque applied to the tensioning nut thus rotates the bolt and expands the anchor shell into gripping engagement with the bore hole wall; torque producing an axial load on the jam nut in excess of its strength causes it to fracture or strip from threaded engagement with the bolt, permitting travel of the tensioning nut.

  • Patent number: 5033910
    Abstract: An improved, radially expansible shell for use in a mechanical expansion anchor and an anchoring system including such a shell in combination with a resin grouting mix, in a drill hole of predetermined diameter. The shell includes a plurality of leaf portions having internal surfaces for engagement by a tapered camming plug as the shell is expanded, external surfaces having a maximum diameter less than that of the drill hole, and side edges. A row of tapered teeth extends outwardly from the external surface of each leaf along one of the side edges thereof. The distance from the central axis of the shell to the crests of the teeth is substantially equal to the radius of the drill hole. The teeth frictionally engage the drill hole wall to retard rotation of the shell and ensure the desired expansion. When the anchor is used with a conventional, two-compartment resin package, the resin components may flow around the shell into the annular space between the external surfaces of the leaves and the drill hole wall.

  • Patent number: 4764055
    Abstract: A resin reinforced expansion anchor system for a mine roof support bolt or the like utilizes a specially configured, thin-walled expansion shell together with a thin-walled, dual-taper plug for expanding the shell. The shell and the plug cooperate to implement a particularly desirable type of mechanical expansion anchoring action while simultaneously providing a symmetrical array of resin flow passages at circumferentially spaced locations about the anchor assembly to permit proper distribution and flow of a quick setting resin mix. The system of the invention enables a relatively large diameter rock bolt or threaded bar to be securely anchored in a blind drilled hole that is of relatively small diameter, with the anchoring action of a mechanical expansion anchor assembly being desirably augumented by the anchoring action of a concurrently established resin bond.

  • Patent number: 4707900
    Abstract: A cylinder liner sleeve puller has four legs having flanged feet at their bottom and being connected by four pivotably mounted pivot arms. The arms are pivotably connected to a central hub, which arrangement forces the lower ends of the legs outward when the hub is manually moved downward. In operation, the legs are inserted into the cylinder so that their bottom extremities are below the lower end of the liner sleeve. The hub is then pressed downward, forcing the lower ends of the legs outward until the flanged feet are directly below the liner sleeve. A jack support plate having spaced holes for the legs is then passed over the legs and rests on the engine block. A hydraulic jack is placed on the support plate, and a top plate is fastened to the top of the legs. When the jack is activated, the plunger pushes the top plate upward, causing a corresponding upward movement of the legs, thereby removing the liner sleeve.
