Dismounting and mounting tool for hoist crane lifting motor

Abstract

The invention discloses a dismounting and mounting tool for a hoist crane lifting motor. The tool comprises two outer side plates which are symmetrically arranged and at least two guide shafts connected between the two outer side plates, guide wheels are arranged in the middle portions of the guide shafts, two moving wheels are arranged above the inner side of each outer side plate, the axes of the four moving wheels are located on the same horizontal plane, the axes of the two guide shafts are located on the same horizontal plane, and positioning rods are located below the inner sides of the two outer side plates; according to the dismounting and mounting tool, a dismounting and mounting workpiece can be wholly suspended on an upper flat beam walking rail through the four moving wheels to transversely move, a hoist crane is fixed to the positioning rods through hooks, a chain on the hoist crane penetrates two moving wheels to be suspended, the suspension end is connected to the position above a crane motor, and therefore through the dismounting and mounting tool, the motor can be driven to transversely and vertically move, and the precise dismounting and mounting position is achieved; through the tool, dismounting and mounting of the crane motor can be completed through extremely small manpower, and the tool can be used for the field of ship construction assisted tools.

Description

technical field [0001] The invention relates to the field of auxiliary tools for ship construction, in particular to a tool for disassembling and assembling a hoist hoisting motor. Background technique [0002] The gourd crane is widely used because of its simple structure, however, the disassembly and assembly tools involved in maintenance have not been solved all the time. The hoist hoisting motor is only 11.5cm away from the hoisting hoisting beam directly below, and it is difficult to realize the vertical, horizontal, and centered installation of the hoisting motor. This problem is prominently manifested in the installation of the motor. When installing the motor, there are three positions that must be aligned, including the alignment of the motor spline and the movable tooth sleeve of the gearbox, the alignment of the motor positioning bearing and the bearing base, and the four key holes of the motor. The four screws of the gourd base must be aligned, the first two of ...

AI Technical Summary

Problems solved by technology

Therefore, no matter what method is used for hoisting, the motor will deviate from its installation center line, and the horizontal, vertical and horizontal vertical forward alignment cannot be guaranteed, and it must be pushed, pulled, and resisted by manpower repeatedly, which is time-consuming and labor-intensive.
