摘要： A clamping device for securing a pole within a U-shaped yoke having a plate member with a hook at one end and a tooth at the other end for respectively engaging opposing slots at the distal ends of the yoke to transversely position the plate across the yoke. A bolt threadingly passes through a hole in the plate to extend in a forward direction on the plate. A bearing plate is rotatably mounted on the forward end of the bolt for abutting the pole and clamping it within the yoke.

摘要： A gripping assembly for moving drilling rigs on offshore drilling platforms in which the drilling rigs are supported on a plurality of skid bases. The gripper assembly rests on the skid bases and provides means for selectively gripping the skid base when a drilling rig is to be moved. The gripper assembly has a platform supported by end plates resting on the skid base flanges and is connected to the drilling rig by a hydraulic jack cylinder which moves or slides the drilling rig on the skid bases in a stepwise fashion. Traversing the platform is a cross-member pivotally supporting gripper arms for applying a clamping force to the skid base. The gripper assembly is clamped on the skid base by means of a clamping hydraulic cylinder to apply a force on flanges on the gripper arms, while the hydraulic jack cylinder is operated to push or pull the drilling rig a distance equal to the extension distance of the hydraulic jack cylinder stroke.
摘要翻译：一种用于在海上钻井平台上移动钻机的夹持组件，其中钻机支撑在多个滑动基座上。夹具组件放置在防滑基座上，并提供了当钻机要移动时选择性地夹紧滑动基座的装置。夹持器组件具有由搁置在防滑基座凸缘上的端板支撑的平台，并且通过液压千斤顶缸连接到钻机，液压千斤顶缸以阶梯方式移动或滑动在钻机基座上的钻机。横向平台是用于向滑动基座施加夹紧力的横向枢转支撑的夹持臂。夹具组件通过夹紧液压缸被夹紧在防滑基座上，以在夹具臂上的法兰上施加力，而液压千斤顶缸被操作以推动或拉动钻机的距离等于液压千斤顶气缸行程。

摘要： An improved post puller includes a U-shaped grapple and a pivot mount providing both a generally vertical pivot position for connection of the grapple to a draw bar and a base for mounting an operating handle thereto. One alternate embodiment provides adjustability. Further, the handle and pivot axis are specifically disposed in varying alternate positions for first rotating the grapple to grasp a post and then to permit rotation about another axis for post pulling. Another alternate embodiment includes a double grapple and actuating apparatus for opening and closing it about a post.

摘要： A transport track and a sliding carriage for transporting heavy loads in substantially horizontal direction. The track comprising a bottom plate intended to be positioned loosely on a support capable to bear heavy loads. The upper surface of the plate and the lower surface of the sliding carriage being designed so as to provide minimum resistance to the movement of the sliding carriage over the surface. At least one rod is attached to the bottom plate which rod is adapted for cooperation with a climbing jack intended for moving the carriage and with a guide groove in the carriage for guiding the carriage during the movement. Structure is also arranged for transferring axial forces arising in the rod to the bottom plate.

摘要： A two-nut, short-stroke screw jack is disclosed having a central threaded member, upper and lower plates, a short-stroke hydraulic jack for lifting the load, and a novel arrangement for driving the upper and lower nuts. A single drive means is used to provide a continuous drive for the lower nut even when the lower nut does not rotate. The upper nut is driven by a resilient coupling means linking the upper and lower nuts. During the first portion of the lifting sub-step, the short stroke jack lifts the load while the drive means rotates the lower nut downwardly. During this first portion of the sub-step, the upper nut is wedged against the upper plate and does not rotate. The lower nut is driven downwardly until it is wedged against the lower plate and the drive means stalls out. During the second portion of the substep, the upper plate is lowered and the upper nut is driven downwardly by means of the resilient coupling linking the upper and lower nuts. The cycle is then repeated for the next stroke.
摘要翻译：公开了一种双螺母短行程螺旋千斤顶，其具有中心螺纹构件，上下板，用于提升负载的短行程液压千斤顶，以及用于驱动上下螺母的新型装置。即使下螺母不旋转，单个驱动装置用于为下螺母提供连续的驱动。上部螺母由连接上部和下部螺母的弹性联接装置驱动。在提升子步骤的第一部分期间，短行程千斤顶提升负载，同时驱动装置向下旋转下螺母。在子步骤的该第一部分期间，上部螺母楔入上部板并且不旋转。下螺母被向下驱动，直到其楔入下板，并且驱动装置失速。在子步骤的第二部分期间，通过连接上部和下部螺母的弹性联接，上部板被降下并且上部螺母被向下驱动。然后重复该循环以进行下一个冲程。
