    Abstract: A slide plate hinge comprises a fixed plate, and a slide plate. A slide plate sliding guide groove is respectively arranged on each of both sides of the fixed plate. The central section of the groove wall at one side of the sliding guide groove is of an elastic structure, and the elastic structure and the groove wall at the other side of the sliding guide groove clamps the slide plate. The slide plate hinge can implement the sliding guide and friction clamping on the slide plate by use of the sliding guide groove of an elastic structure, with high structural integration and concealability, thereby enabling the slide plate hinge to still have good hand feeling even without driving springs and enabling the slide plate to be stopped at any time amid the sliding process. The driving springs are not indispensable, so the thickness of the hinge can be reduced.

    Abstract: A system for delivering a downhole tubular from a rack at an oilfield surface to a rig floor thereat. The system includes a trough for accommodating the tubular that is slidably engaged with a lift frame in a sledded fashion. Thus, for delivery of the tubular, the trough may be sleddingly extended from the lift frame. That is, as opposed to a roller type of coupling between the trough and tubular, a sledded coupling is utilized that may require comparatively less maintenance and mobilization time. This may be particularly the case where lighter weight tubulars of less than about 1,000 lbs., preferably under about 500 lbs., are being delivered.

  • Patent number: 8439566
    Abstract: A cam assembly is provided for adjustment of a drill feed guide wear pad. The cam assembly has an eccentric bushing with a shank portion extending circumferentially about a first axis and defining a bore along a second axis. The second axis is generally parallel and offset from the first axis. The bushing has a head portion extending from the eccentric bushing portion, with the bore extending though the head portion. The bushing is sized for insertion into an aperture of a drill feed guide wear pad, and is rotatable causing the shank portion to engage the aperture of the wear pad to provide a camming action to position the wear pad relative to a drill feed guide. The head portion is shaped to interact with a tool for rotating the bushing.

  • Patent number: 8282282
    Abstract: A motion guide device is able to damp a moving block from vibrating in a direction perpendicular to an axis of a raceway rail. A damping plate with a surface facing a surface of a raceway is provided at a moving block body. The surface of the damping plate is set to be in contact with the raceway rail or is set such that a gap between its surface of the raceway rail is as close to zero as possible. When vibration occurs from the raceway rail or the moving block, the surface of the raceway rail and the surface of the damping plate come into contact with each other. This brings about change in a spring constant of the motion guide device in the direction perpendicular to the axis of the raceway.

  • Publication number: 20120251284
    Abstract: A boom assembly includes a first boom member and a second boom member slidable relative to the first member in a first direction. A stop member that at least partially defines a receptacle is attached to the first member. A closure member is attachable to the first member in a fixed position and movable away from the fixed position. A planar wearpad is insertable into the receptacle in the first direction when the closure member is moved away from the fixed position and the second member is positioned on the first member. The stop and closure members inhibit lateral movement of the wearpad in a direction parallel to the plane of the wearpad, and allow movement of the wearpad in a direction transverse to the plane, when the wearpad is positioned in the receptacle. The second member inhibits movement of the wearpad in the direction transverse to the plane.
