Abstract

An intelligent subway rail welding vehicle comprises a frame (1), a cab (4), a functional room (2), an operation room (5) and a welding machine room (21) are arranged above the frame (1), a power transmission system (6) and a hydraulic oil tank (14) are arranged in the functional room (2), an office area and an operation area are arranged in the operation room (5), a welding machine (19) and a welding machine take-up and pay-off device (20) is arranged in the welding room (21). A front driving bogie (9), a diesel tank (7) and a rear driving bogie (10) are arranged below the frame (1); escalators (13) are arranged on the two sides of the front drive bogie (9); and an overturn door (17) is arranged at the end of the welding machine room (21). The intelligent subway rail welding vehicle can automatically run to a rail welding site to conduct online welding, offline welding and base welding, and if extreme derailment occurs, the vehicle can be rapidly lifted and restored; all operations inthe operation process are designed mechanically and automatically.

Description

technical field [0001] The invention relates to a subway rail welding car, which belongs to the technical field of urban rail transit machinery design and manufacture. Background technique [0002] my country's urban rail transit is developing rapidly. At present, 39 cities have been approved by the State Council to build urban rail lines, and there will be more than 50 cities by 2020, with a total length of 6,000 kilometers. The demand for maintenance equipment for urban rail is increasingly apparent. At present, domestic subway rail welding mainly adopts thermite welding, small air pressure welding, container flash welding rail car, and subway flash welding rail car. Since the welding quality of thermite welding and small gas pressure welding is difficult to guarantee, the container-type flash welding rail car can guarantee the quality, but it needs to be equipped with special flat cars and tractors, and the operation efficiency is low. The existing subway rail welding c...
