The invention belongs to the technical field of lifting equipment, and provides a pressure release device of a lifting cage variable-speed motor control system. The device comprises a mounting rod, the mounting rod is connected with a variable-speed rod, a slot is formed in the mounting rod, a crank is arranged in the slot, and one end of the crank is connected with a screw; a rotary connecting part is arranged in the slot and is connected with a first control rod; the crank and the screw can also be replaced by the cooperation of a shell adjusting screw and a screw support, and the same technical effect can be achieved; pressure of variable-speed clutch balls is released, so that the variable-speed clutch balls are not prone to damage, the service life of a clutch is prolonged, and the overall working efficiency is improved; and other power devices except for electric power are adopted, dependence on the electric power can be weakened, normal work can still be achieved in the environment with insufficient electric power, a variable-speed device can conveniently adjust the speed of a power device, the adjustable range is large, speed adjustment is convenient, and the defect that inthe prior art, excessive dependence on the electric power exists is overcome.

    本发明属于升降设备技术领域,提供了一种提升罐笼变速机控制系统的压力释放装置,包括安装杆,安装杆与变速杆连接,安装杆上开设有狭槽,狭槽内设有曲柄,曲柄的一端与螺钉连接;狭槽内设有转动连接部件,转动连接部件与控制杆一连接;所述曲柄和螺钉也可以替换为壳调节螺钉和螺钉支座的配合,可以实现相同的技术效果;本发明对变速的离合器滚珠的压力进行释放,使其不容易损坏,延长离合器的使用寿命,提高整体的工作效率;采用了电力以外的其他动力装置,能够减弱对电力的依赖,使在电力不充足的环境中,依然可以正常工作,变速装置能够方便的对动力装置进行调速,可调范围大,调速方便,克服了现有技术中过度依赖电力的缺陷。
