| description | A gravity center adjusting structure of a hoisting device comprises a cross beam, the front end and the rear end of the cross beam are connected with hoisting rings through steel cables, an up-down adjusting device is arranged between one steel cable and the cross beam, a front hoisting assembly is arranged below the front end of the cross beam, and the rear end of the cross beam is connected with a rear hoisting assembly. The up-down distance between the lifting ring and the front end of the cross beam is adjusted through the up-down adjusting device, up-down gravity center adjustment can be carried out on front and back lifting points of the engine according to the lever principle, through cooperation of a nut and a lead screw of the back lifting assembly, the lead screw moves left and right to achieve left-right gravity center adjustment of the engine, and the device is simple in structure, convenient, fast and practical. The method is suitable for popularization and use in the aviation maintenance field. |
