Urban rail vehicle vehicle-mounted automatic rail detection device

Abstract

The present invention is a vehicle-mounted automatic track detection device for urban rail vehicles, which can greatly reduce the workload of construction workers and the utilization rate of large-scale detection equipment; the present invention consists of a track detection and line inspection system, a gauge detection system, a rail profile detection system, The third rail detection system, train positioning system and other systems constitute. The entire detection system consists of three parts: chassis and bogie suspension equipment, including power supply, lighting, camera, laser, ultrasonic and other systems; computer information processing system in the passenger room (usually placed under the passenger seat); driver's cab or control system. Center display system. The automatic track detection system mainly detects the status of the track, the third rail and other accessories of the track. Generally choose to install the automatic track detection system on 2~3 trains in the operating fleet, complete the detection of the track system during the daily passenger operation of the train, and send the detection results to the ground control center (OCC).

Description

technical field [0001] The invention relates to a detection device, in particular to a vehicle-mounted automatic track detection device for urban rail vehicles. Background technique [0002] By the end of 2013, as many as 80 urban rail lines had been opened in nearly 20 cities in my country, with a total mileage of 2,400km, most of which were built underground or elevated. Tracks are important equipment for carrying and guiding trains to run safely, and maintaining a good condition is crucial to operational safety. Due to the long-term contact with the wheel and rail, the track will produce various track irregularities, surface wear and defects under the action of power. Various track irregularities lead to loosening of track fasteners and damage to infrastructure under the track downwards; upwards cause changes in the stability and comfort of rail vehicles, and even cause vicious events such as derailment and overturning; for the track itself, it may cause Rail cracks eve...

Problems solved by technology

Compared with traditional manual inspection, large-scale professional inspection equipment has the following advantages and disadvantages: high precision, complete inspection items, fast speed, data can be managed, and it is convenient for in-depth analysis. Large-scale professional track inspection equipment requires a large amount of capital investment in the early stage, and the cost is high In addition, special drivers and passengers need to be allocated, which increases the cost of public works
