Down-grinding-type contact rail fault overhaul vehicle

Abstract

The invention discloses a down-grinding-type contact rail fault overhaul vehicle. The down-grinding-type contact rail fault overhaul vehicle comprises a vehicle body, an image acquisition device, a leveling device, a storage device, a control system, a driving device and a braking device. The vehicle body is located above a traveling rail and is used for storing overhaul equipment. The vehicle body can move along the contact rail under the driving of the driving device. The image acquisition device is used for inspecting a running state of the contact rail, and the inspected image is stored in the storage device. A standard image database is further stored in the storage device. An automatic comparison module of the control system compares images collected by the image acquisition device with standard images, and transmits the compared results to a controller of the control system. Through comparison, if the contact rail is a faulty contact rail, the controller controls the braking device, so that the overhaul vehicle can stop and overhaul, and it is ensured that the problem can be dealt with in the first time after discovery, thus the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of track detection for urban rail transit traction power supply systems, in particular to a ground-grinding type contact rail fault maintenance vehicle. Background technique [0002] In the traction power supply system of urban rail transit, part of the lower grinding contact rail system is used. During the maintenance process of the contact rail equipment, it is required to inspect the contact rail equipment once a month. The lower grinding contact rail is protected by a protective cover. Reflectors are needed during the process, and there are the following problems: low inspection efficiency, blurred reflection images, difficulty in finding equipment defects, holding the reflector for a long time, relying on mirror emission to observe the condition of the contact rail, maintenance personnel need to carry common maintenance during the inspection Tools, spare parts, walking in the rail area for a long time, ...

[0002] In the traction power supply system of urban rail transit, part of the lower grinding contact rail system is used. During the maintenance process of the contact rail equipment, it is required to inspect the contact rail equipment once a month. The lower grinding contact rail is protected by a protective cover. Reflectors are needed during the process, and there are the following problems: low inspection efficiency, blurred reflection images, difficulty in finding equipment defects, holding the reflector for a long time, relying on mirror emission to observe the condition of the contact rail, maintenance personnel need to carry common maintenance during the inspection Tools, spare parts, walking in the rail area for a long time, causing sore arms and shoulders, and large spare parts cannot be carried to the site, so that once a problem is found, it cannot be dealt with immediately (the emergency repair point is about 26 kilometers away from the farthest station) , has an impact on the urban rail transit traction power supply system
