The invention relates to a hydraulic oil cylinder, in particular to a hydraulic oil cylinder leakproof device and a hydraulic oil cylinder. The hydraulic oil cylinder leakproof device comprises an underframe, a lifting assembly, a pressure relief prompting assembly, a speed retarding assembly and the like; and the lifting assembly is arranged above the underframe, the pressure relief prompting assembly is arranged on the lifting assembly, and the speed retarding assembly is arranged on the underframe. When a hydraulic system is locked, a piston block and a device on the piston block can be kept at a proper height under the self-locking effect of a rotating lead screw, when hydraulic oil leaks, a piston rod and a heavy object on the piston rod tend to fall under the effect of gravity, force acts on the combination face of an impeller and the rotating lead screw, small torque is generated, the piston rod is prevented from falling, and therefore, even if liquid leaks from the equipment, the normal working state of the hydraulic system can be kept, and the heavy object lifted on the piston rod cannot fall off suddenly.
本发明涉及一种液压油缸,尤其涉及液压油缸防泄漏装置及液压油缸,包括有底架、上升组件、泄压提示组件、缓速组件等;底架上方设有上升组件,上升组件上设有泄压提示组件,缓速组件设于底架上。在液压系统锁死时,活塞块及其上装置会在旋转丝杠的自锁作用下保持在合适的高度,当出现液压油泄漏时,活塞杆及其上的重物会在重力的作用下有下落的趋势,力作用在叶轮和旋转丝杠的结合面上,产生小的扭矩,阻止活塞杆下落,从而使得该设备即使发生漏液,也可以保持液压系统正常工作状态,不会使活塞杆上托举的重物突然脱落。
