An automatic maintenance vehicle for subway tracks

Abstract

The invention relates to an automatic maintenance vehicle for a subway rail. The automatic maintenance vehicle comprises a base plate, wherein two rows of support columns are symmetrically arranged in the middle of the lower end of the base plate, rail cleaning devices are installed on the lower ends of the two rows of support columns, the two rows of support columns have the effects of stably supporting the rail cleaning devices, and the rail cleaning devices have the automatic cleaning functions in the middle of the rail; four support legs are symmetrically arranged on the lower end of the base plate, four universal wheels are respectively arranged on the lower ends of the support legs, and the automatic maintenance vehicle can be moved to a designated position by virtue of the four universal wheels on the four support legs; a rail tree trimming device is arranged on the left side of the upper end surface of the base plate, the rail tree trimming device has an automatic trimming function on rail protection trees, a rail stone pushing and shoving device is installed on the right side of the upper end surface of the base plate, and the rail stone pushing and shoving device has an automatic pushing and shoving function on rail vibration reduction stones. According to the automatic maintenance vehicle, the integrated automatic rail maintenance functions of trimming the trees, pushing and shoving the stones and cleaning can be realized.

Description

technical field [0001] The invention relates to the field of rail technology, in particular to an automatic maintenance vehicle for subway rails. Background technique [0002] With the continuous development of rail technology in China, rails are mainly divided into high-speed rails, bullet train rails, train rails, and subway rails. Due to the increasing number of rails, the number of rail maintenance workers is also increasing. The existing rail maintenance mainly It is divided into checking the rail device, trimming the protective trees on both sides of the rail, pushing the damping stones on both sides of the rail, and removing impurities in the middle of the rail, etc. However, the existing rail maintenance methods have the following defects: 1. The trees on both sides of the rail need to be protected and trimmed manually , the pruning time is long, the pruning speed is slow, and the pruning effect is poor. After pruning, it is necessary to manually cut the pruned branc...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides an automatic maintenance vehicle for subway tracks, which can solve the problems of complex operation, high labor intensity, low degree of automation, low work efficiency, manual pruning of protective trees, and pruning of existing rail maintenance methods. Slow speed, long pruning time, poor pruning effect, manual cutting of branches after pruning, manual pushing of stones, long pushing time, slow pushing speed, poor pushing effect, regular manual removal of impurities, removal speed It can realize the integrated automatic maintenance function of tree pruning, stone pushing, and impurity removal on the rails without manual operation. It is easy to operate, low in labor intensity, high in automation, and high in work efficiency. Automatic pruning of protective trees, fast pruning speed, short pruning time, good pruning effect, automatic cutting of branches after pruning, automatic pushing of stones, short pushing time, fast pushing speed, good pushing effect, automatic removal of impurities, removal of The advantages of fast impurity speed and good impurity removal effect
