摘要： The present invention has at least one rack chock which is supported pivotally and tiltably at one end by a pin and cross head assembly located at a position between at least one leg rack and the hull of the platform. The other end of the rack chock is connected to the jack foundation with an actuator assembly. The pin and cross head assembly is disposed slidably within a guide for permitting the teeth of the rack chock to engage the leg rack teeth without visual monitoring and manual control. The actuator assembly connected to the other end of the rack chock controls the swinging movement of the rack chock and its engagement and disengagement with the leg rack. A pair of jacks urges upper and lower wedges with tiltable surfaces converging onto the rack chord's upper and lower surfaces, thus obtaining a optimal surface to arrest the relative movement between the rack chock and the leg rack. As such, load from the jack foundation is transferred to the legs, overturning moments on the legs to the jack foundation. Stress to the mating surfaces of the present invention and the leg rack is minimized as the engagement of the present invention takes place under load from the inertia load of the rack chock due to the pivoting action with minimum forcing action from the actuator assembly.
摘要翻译：本发明具有至少一个齿条轴承座，其在一端由位于至少一个支架架和平台的船体之间的位置处的销和十字头组件支撑地枢转地和可倾斜地支撑。机架轴承座的另一端通过执行器组件连接到千斤顶基座。销和十字头组件可滑动地设置在引导件内，以允许齿条轴承座的齿接合腿齿条齿，而无需可视监视和手动控制。连接到齿条轴承座另一端的执行器组件控制齿条轴承座的摆动运动及其与腿架的接合和分离。一对千斤顶促使具有可倾斜的表面的上下楔形物收敛到齿条和弦的上表面和下表面上，从而获得最佳表面以阻止齿条轴承座与支架架之间的相对运动。因此，千斤顶基座的载荷被转移到腿部，将腿上的扭矩翻转到千斤顶基座。由于本发明的接合由于来自致动器组件的最小强制作用的枢转作用而在来自齿条轴承座的惯性负载的负载下发生，所以对本发明和腿架的配合表面的应力被最小化。
