摘要： A tool for gripping a flat or curved plate in an end region thereof, for example, the flange (21) of a beam (10) in order to move the beam or to move an object relative thereto, comprising a pair of opposed body members (16) each with a ball or roller cage (17) and balls or rollers (18) residing on ramps (19) on the body members. Springs (20) urge the ball or roller cages (17) in a gripping direction where the balls or rollers are approaching the peaks of the ramps. An actuator (not shown) attached by a connecting rod (13) and pivot (14) to one of the body members (16) causes the beam to be gripped by the tool. Thus, the tool may crawl along the beam by reciprocating operation of the actuator, or alternatively may serve to pull the beam in the direction of arrow (30).

摘要： A tool for gripping the circumferential outer surface of a pipe or rod (11) and comprising a pair of diametrically opposed arcuate shoes (10) each with a ball cage (14) having a plurality of balls retained by the cage. The shoes (10) have ramped surfaces upon which the balls will run so that when the shoes (10) are rotated about the central longitudinal axis of the pipe or rod (11) the balls become trapped between the ramp surfaces (18) and the surface of the pipe or rod, to grip same. Reverse rotation releases the tool. The rolling action imposed by the balls (15) on the pipe or rod (11), whilst gripping same, avoids the creation of sharp burrs on the surface of the pipe or rod thus helping to prevent corrosion.

摘要： A connector principally but not necessarily for underwater anchorage comprising a probe (100) insertable within a receptacle (101) adapted to be anchored at (102) at a fixed location, the probe (100) comprising an internal mandrel (3) having an external ball or roller cage (7) with balls or rollers (8) riding upon respective ramps (110) of the mandrel whereby the balls or rollers (8) may engage the internal wall surface of the receptacle (101) to lock the probe and receptacle together when a load is applied to the mandrel attempting to separate the two parts. Sleeves (10) and (12) are spring-loaded apart by springs (1), and a pin (2) is removable to enable the sleeves (10) and (12) to move apart such that a circumferential array of balls (14) ride up associated reverse ramps (9) to lock the sleeve (10) and ball cage (7) with respect to mandrel (3) thus preventing retraction of the balls or rollers (8), and maintaining the probe (1) and receptacle (101) in locked relationship.
摘要翻译：主要但不一定用于水下锚固的连接器，其包括可插入适于在固定位置处（102）锚固的容器（101）内的探针（100），所述探针（100）包括内部心轴（3），其具有外部球或滚子保持架（7），其中滚珠或滚子（8）骑在心轴的相应斜面（110）上，由此滚珠或滚子（8）可以接合插座（101）的内壁表面，以锁定探针和插座一旦将负载施加到试图分离两个部件的心轴上时，则一起使用。套筒（10）和（12）由弹簧（1）弹簧加载，并且销（2）是可拆卸的，使得套筒（10）和（12）能够移开，使得圆周阵列的球（14 ）相对于心轴（3）骑起相关联的反向斜坡（9）以锁定套筒（10）和球保持架（7），从而防止滚珠或滚子（8）的缩回，并且保持探针（1）和容器（101）锁定关系。

摘要： A tool for gripping tubular objects such as pipes or hollow piles by contact with opposed internal or external surfaces thereof to enable the object to be recovered from its location such as in a subsea application. The tool comprises a mandrel (1) carrying several annular arrays of gripping members each comprising a body (2) a ramped wedge member (15) and a ball or roller cage (18). Hydraulic actuators (29) and control rods (31) are connected to tendons (12) which are themselves connected to the wedge members (15) and ball or roller cages (18) thus, upon engagement of the actuators (29) to draw the roller cages (18) and wedges (15) into a condition to grip the surface of the object, and selectively then to draw the wedges (15) and ball or roller cages (18) out of engagement with the surface of the object thus positively to release the tool from the object.
摘要翻译：用于通过与其相对的内表面或外表面接触来夹紧管状物体（例如管道或空心桩）的工具，以使物体能够从其位置（例如在海底应用中）回收。该工具包括承载多个环形阵列的夹紧构件的心轴（1），每个夹持构件包括主体（2）倾斜的楔形构件（15）和球或滚柱保持架（18）。液压致动器（29）和控制杆（31）连接到钢筋（12），钢筋（12）本身连接到楔形件（15）和球或滚笼笼（18）上，因此在致动器（29）接合时，辊笼（18）和楔子（15）成为夹持物体表面的状态，然后选择性地将楔形物（15）和球形或笼式货架（18）拉出与物体的表面接合，因此如此积极地从对象释放工具。
