The invention relates to the technical field of hydraulic hoists, in particular to a speed-adjustable hydraulic hoist with a safety protection function, which comprises a hoisting track, a hydraulic hoist is slidably arranged on the hoisting track, the speed of the hydraulic hoist on the hoisting track is adjustable, and the hydraulic hoist is connected with a lifting hook through a steel cable, a first connecting block and a second connecting block. The second connecting block can rotate relative to the first connecting block, the elastic piece is arranged at the rotating joint, when the gravity center of the second connecting block is changed, the second connecting block can rotate relative to the first connecting block, then the swing potential energy of the lifting hook is converted into kinetic energy of force storage of the elastic piece, and therefore the swing amplitude of the lifting hook can be effectively reduced; the abrasion of the steel cable and the lifting hook is reduced, and meanwhile, safety accidents can be avoided.

    本发明涉及液压葫芦技术领域,具体提供了一种具有安全保护功能的可调速液压葫芦,包括吊装轨道,吊装轨道上滑动设置有液压葫芦,液压葫芦在吊装轨道上的速度可调,液压葫芦与吊钩之间通过钢缆、第一连接块和第二连接块连接,第二连接块能够相对于第一连接块转动,且转动连接处设置有弹性件,当第二连接块的重心改变时能够使得第二连接块相对于第一连接块转动,进而将吊钩摆动的势能转化为弹性件蓄力的动能,从而能够有效的减少吊钩摆动的幅度,降低钢缆和吊钩的磨损,同时能够避免安全事故的发生。
