Description

Technical Field

[0001] The present invention relates to the technical field of track detection auxiliary equipment, and in particular to a self-propelled track platform vehicle and track detection equipment. Background Art

[0002] In order to adapt to the vigorous development of high-speed, heavy-load and conventional railways in my country, the track maintenance industry is developing towards intelligence, automation and integration, and the demand for integrated and intelligent track maintenance equipment is increasing day by day. At present, track flaw detection, inspection and other inspection equipment must be operated by hand, with low operating efficiency and high labor costs. Although there are some large-scale comprehensive inspection trains that can provide automatic inspection, the cost is high, and it is difficult to get on and off the track, and it is inconvenient to use and maintain. Therefore, the demand for some rail electric vehicles is getting higher and higher.

[0003] Existing rail electric vehicles have become a technical field that has been vigorously developed at home and abroad due to their high efficiency and green advantages.

The equipment can realize self-propelled automatic detection, has a high degree of automation, and is compact and flexible. Although the modular design of each detection system facilitates transportation and installation to a certain extent, the entire self-propelled platform is an integral structure and still requires special transportation tools to be transported to the track inspection site. It is also large in size and can only be transported through a special channel. It is not very convenient in actual use, and special tools or multiple people are required to cooperate when unloading, which increases the labor intensity of maintenance workers.
