    • A new alternative uplock release assembly is provided. The assembly comprises a pivot pin having a first end and a second end and an internal bore, a release system operatively connected to the first end of the pivot pin, said release system comprising a cylinder and a piston, said piston having a piston head and an elongated member passing longitudinally through said bore, said cylinder having a pressure port through which a pressure source can be fed. The assembly further comprises a hooking member, a torque member rotatably mounted at the second end of the pivot pin, a biasing system operatively connected to the torque member, said biasing system having a bias cylinder and a biasing means located within the bias cylinder. When biasing force is applied to the torque member, an interlocking means to enable the rotatable interconnection between the torque member and the hooking member in a locked and first position, and an engaging means to interconnect the torque member with a link member. When torque is applied to the link member, the torque is transferred, via the engaging means and interlocking means, to the hooking member forcing the hooking member to rotate around the pivot pin. During alternative operation, pressure is fed through the pressure port, the piston counteracts the biasing force, thereby translating the torque member longitudinally over the pivot pin sufficiently to decouple the torque member and the hooking member from the said locked and first position, to an unlocked and second position enabling the hooking member to rotate around the pivot pin.
    • 提供了一种新的可选择的上锁释放组件。 组件包括具有第一端和第二端以及内孔的枢轴销,可操作地连接到枢转销的第一端的释放系统,所述释放系统包括气缸和活塞,所述活塞具有活塞头和 细长构件纵向通过所述孔,所述圆筒具有压力端口,压力源可以通过该压力端口供给。 所述组件还包括钩构件,可转动地安装在所述枢转销的第二端处的扭矩构件,与所述扭矩构件可操作地连接的偏置系统,所述偏置系统具有偏置气缸和位于偏置气缸内的偏置装置。 当向扭矩构件施加偏置力时,能够在扭转构件和钩挂构件之间在锁定和第一位置中的可旋转互连的互锁装置以及将扭矩构件与连杆构件互连的接合装置。 当扭矩施加到连杆构件时,扭矩通过接合装置和互锁装置传递到使挂钩构件围绕枢转销旋转的钩构件。 在替代操作期间,压力通过压力端口进入,活塞抵消偏压力,从而使扭矩构件在枢轴销上纵向平移,足以将扭矩构件和钩挂构件从所述锁定和第一位置解耦到解锁 以及第二位置,使得所述钩构件能够围绕所述枢转销旋转。
