Hoisting mechanism for casing of gearbox

Abstract

The invention provides a hoisting mechanism for a casing of a gearbox. The hoisting mechanism comprises a hoisting support, two pitch adjusting mechanisms and two lifting hook structures capable of hoisting the casing of the gearbox, wherein the hoisting support comprises a main supporting plate, a fixing plate and two auxiliary supporting plates, the two auxiliary supporting plates are symmetrically arranged on left and right end surfaces of the main supporting plate respectively, and the fixing plate is arranged on the lower end surface of the main supporting plate; a lifting ring structureis arranged in the middle of the upper end surface of the main supporting plate; and each pitch adjusting mechanism comprises a pitch adjusting plate and a pitch adjusting screw, the middle of each pitch adjusting plate is hollow, one end of each pitch adjusting plate is rotationally connected with the fixing plate, the other end of each pitch adjusting plate is in threaded connection with the corresponding pitch adjusting screw, the other end of each pitch adjusting screw is connected with the corresponding lifting hook structure through a corresponding fixing ring, and a steel wire rope partof each lifting hook structure penetrates through the auxiliary supporting plate adjacent to the corresponding pitch adjusting mechanism. With the adoption of the hoisting mechanism for the casing ofthe gearbox, the technical problem that safety accidents occur due to the fact that a lifting hook can slide on a casing of a gearbox when the casing of the gearbox is hoisted by a traditional hoisting mechanism is solved.

Description

technical field [0001] The invention belongs to the field of gearbox casing manufacturing, and in particular relates to a hoisting mechanism for a gearbox casing. Background technique [0002] During the processing of the gearbox housing, the type of blank must first be selected. The blank of the gearbox housing is generally made of castings. Then, according to the analysis of the benchmark and the installation plan, the blank needs to be milled, drilled or polished by the machine tool. operate. [0003] During the processing process, it is necessary to use the crane in the production workshop to hoist the gearbox casing to realize the transfer of the gearbox casing between various processing equipment and warehouses. Since the overall center of gravity of the gearbox casing is not at the center of the gearbox casing, the gearbox casing is tilted during the hoisting process, and the traditional hoisting mechanism may cause the hoisting of the gearbox casing during the lifti...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims to propose a hoisting mechanism for the gearbox casing, which solves the problem that the traditional hoisting mechanism may cause the hook to slide on the gearbox casing during the operation of the gearbox casing, and then Technical issues leading to security incidents

[0005] And it is further solved that because the gearbox housing is in a tilted state during the lifting process, it is not easy to realize the accurate one-step positioning of the gearbox housing on the CNC machining center or machine tool processing seat, and workers still need to process it after removing the lifting belt. The gearbox housing on the seat moves, the labor intensity of the workers is high, and the technical problems of low work efficiency
