Crane hoist trolley for easy maintenance

Abstract

The invention discloses a conveniently overhauled crane carriage for a crane. A movable maintenance platform is arranged on the crane carriage. A crane carriage frame comprises two walking beams and a bearing beam which are arranged in an I shape. The two ends of each winding drum are arranged on two winding drum fixing bases respectively. A dedicated monitoring device comprises an installing frame composed of two fixed segments and a horizontal segment. A driving chain wheel, a driven chain wheel and a chain are arranged in the horizontal segment, a horizontal mobile platform is fixed to the chain, and a rotary mobile platform is rotationally connected to the horizontal mobile platform. According to the conveniently overhauled crane carriage for the crane, the crane carriage can be produced through a modularized assembling mode and has the advantages of being simple in structure, few in welding point and light in self weight, welding portions can be decreased effectively at the same time, and the situation that the errors of crane carriage wheel lines are too large due to welding deformation is avoided; in addition, whether the surface of a main beam has deformation or cracks or the working conditions of driving wheels and driven wheels can be monitored in real time through a camera, and meanwhile the overhauling efficiency is improved.

Description

technical field [0001] The invention relates to a crane trolley, in particular to a crane trolley which is convenient for maintenance. Background technique [0002] The lifting trolley is a part of the bridge type crane. The lifting trolley runs horizontally along the main beam laid on the bridge frame. It can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is widely used in indoor and outdoor warehouses and factories. , docks and open-air storage yards, etc., most of the existing bridge cranes use lifting trolleys to realize lateral movement. However, during use, due to the high erection height of the lifting trolley, it is difficult to monitor the working status of the lifting trolley in real time. In the maintenance work of the existing trolleys, especially for some modular trolleys that have not been fully enclosed (that is, trolleys without wheel covers), it is necessary to check whether there are defor...

AI Technical Summary

Problems solved by technology

The existing maintenance method is usually that the maintenance personnel climb the end beams on the elevated sides on both sides, and then board the maintenance platform of the lifting trolley for maintenance, which has safety risks and low maintenance efficiency; at the same time, the existing maintenance platform of the lifting trolley Mostly fixed installation, occupying space

However, the existing lifting trolleys, especially the modular trolleys that have not been fully enclosed, can directly observe whether there is deformation or crack on the surface of the main beam or the working status of the driving wheel and the driven wheel.
