Description

Technical Field

[0001] The utility model relates to the technical field of urban rail power supply, in particular to a surface treatment device for a rigid contact line. Background Art

[0002] The rigid contact network is an important component of the urban rail transit contact network system. Its contact line is very easy to wear during the current collection and contact between the bow and the network. The wear will not only affect the matching relationship between the bow and the network, but also accelerate the wear of the contact line and the pantograph, shortening the service life of the rigid contact network and the pantograph. The rigid contact network often has poor elasticity and uneven wear in local sections. At the same time, there is also the problem of irregular wear of the carbon slide plate of the electric passenger car pantograph, which requires a surface treatment device. The existing surface treatment device for some rigid contact lines cannot adjust the clamping width of the bus when grinding the rigid contact line, and cannot drive the device to move while clamping, which is not convenient for sliding processing, affecting the working efficiency of the device.
