Description

Pantograph carbon slide plate Technical Field The utility model relates to the technical field of rail transit equipment, in particular to a pantograph carbon slide plate. Background The pantograph carbon slide plate is directly contacted with the contact net at the top of the rail transit vehicle, so that stable current is provided for the operation of the subway. It is difficult to avoid abrasion of the carbon skateboard during the running process of the train, and the abrasion of the surface of the carbon skateboard is uniform under the condition of normal running. However, the sliding plate is influenced by factors such as contact pressure of the bow net, material quality of the carbon sliding plate, environment and the like, so that the carbon sliding plate generates abnormal abrasion, and the phenomenon that the surface of the carbon sliding plate is raised or recessed is shown. Most of the current subway lines use a metal-immersed sliding plate, metal in the sliding plate is copper, hard points are formed after copper is melted and separated out, the sliding plate and a contact line form dry friction, arcing is generated, the contact line is drawn, and abnormal abrasion is formed by vicious circulation. Under the abnormal abrasion state, the three-dimensional shape of the surface of the carbon slide plate is rugged and rough, the contact condition is bad, the back bow gateway system is rapidly deteriorated when abnormal abrasion occurs, if the abnormal abrasion is not controlled in time, the abrasion rate of the carbon slide plate is increased by tens of times, the abrasion of the contact line is aggravated, and the normal operation of a circuit can be influenced when the abnormal abrasion occurs. The current method for monitoring the condition of the carbon slide plate (such as CN 205871761U) mainly comprises the steps of installing a copper pipe at a position close to the scrapped position of the carbon slide plate, leading out the copper pipe from two ends of the carbon slide plate and connecting the copper pipe into a gas circuit, and sending out a signal when the gas pressure changes after the copper pipe is worn and damaged. The monitoring method mainly comprises the steps of installing a copper pipe in the carbon sliding plate near the scrapped part, leading out two ends of the copper pipe from the sliding plate, and then connecting the copper pipe into a gas circuit, wherein the gas pressure changes after the copper pipe is worn and damaged, so that a signal is sent out. The copper pipe is single in position and can send out a signal only when scrapped. This approach only detects whether the carbon sled is scrapped and does not monitor the wear of the carbon sled during the use phase. The current patents related to carbon skateboards mainly monitor the thickness variation of the carbon skateboards, and cannot monitor whether abnormal abrasion occurs on the carbon skateboards. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides the pantograph carbon slide plate which has a simple and reliable structure and can monitor the abnormal abrasion of the carbon slide plate body before the thickness of the carbon slide plate body is abraded.

As a further improvement of the above technical scheme: The holding groove has been seted up to one side of carbon slide body, monitoring facilities inlays and locates in the holding groove. The first metal sheet is clung to one side of the containing groove close to the carbon slide plate body, and the second metal sheet is clung to one side of the containing groove far away from the carbon slide plate body.
