The invention relates to a hoisting tool, in particular to a gantry power-assisted hoisting device which comprises a cross beam, supporting legs located at the two ends of the cross beam, a hoisting movement assembly, a hoisting translation assembly, a hoisting rotating mechanism and a power air cylinder. Supporting legs at the two ends of the cross beam are parallel to each other and installed on the horizontal plane, a lifting translation assembly is arranged on the lower portion of the cross beam located between the two supporting legs, the lower end of the lifting translation assembly is connected to a lifting rotating mechanism, and the lower end of the lifting rotating mechanism is fixedly connected to a lifting movement assembly. One end of the hoisting movement assembly is a power end, the other end of the hoisting movement assembly is a hoisting end, the power air cylinder is installed at the power end of the hoisting movement assembly, and the hoisting end is connected with a hoisting hook through a steel wire rope; a moving form is adopted, so that free movement is realized; free rotation of the hoisting device is achieved through the rotating mechanism, power-assisted hoisting is achieved in a pneumatic mode, and the hoisting device has the advantages of being simple in structure, convenient to operate and the like. The manufacturing cost of the hoisting equipment is reduced, the economic benefit is improved, and the working efficiency is improved.

    本发明涉及起吊工装,具体是涉及龙门助力起吊装置,包括:横梁、位于横梁两端的支腿、起吊运动组件、起吊平移组件、起吊旋转机构、动力气缸;横梁两端的支腿相互平行且安装于水平面上,位于两支腿之间的横梁下部设有起吊平移组件,起吊平移组件下端连接在起吊旋转机构上,起吊旋转机构下端固定连接在起吊运动组件上;所述起吊运动组件一端为动力端,另一端为起吊端,所述动力气缸安装在起吊运动组件的动力端,起吊端通过钢丝绳连接有起吊钩;采用移动形式,实现自由移动;通过转动机构实现起吊装置实现自由旋转,采用气动方式实现助力起吊,具有结构简单、操作方便等优点;降低了起吊设备的制造成本,提高经济效益,增加工作效率。
