How to solve the following problems of the sliding contact line?

The reason of power failure in the over-contact line: the brush appears climbing in the conductor, which leads to serious wear of the brush and can't effectively touch the conductor, or the conductor appears uneven on the joint, and the guide rail appears loose on the joint, etc. The solution is: only the electrical brush wear inspection, and the serious wear collector replacement; Readjust the brush at the connected node; Tighten the connecting screw again.

The guide is deformed, so the collector is hindered in operation: the temperature may be too high in the environment; Or the space between the lifting rack is larger and looser; Solution: local use of heat insulation board, and in the outdoor sun visor; Increase the number of the slide contact line in the lifting rack, and then correct the conductor and tighten the screws.

During the working process, the sloshing of the sliding contact line is relatively large: the fork cannot absorb the transmission error well; The guideway itself is relatively poor in straightness; The lift hanger is seriously loose; The solution is as follows: to repair the tractor to ensure that it can freely absorb the transmission error; And to guide the straightness of effective adjustment; Then adjust the tightness of the screws on the lifting rack.

Brush wear faster: in the joint is not flat; Large carrying capacity; Or the pressure of the spring is so great; The solution is: according to the relevant requirements to reconnect the guide rail; And to the collector in the number of increase; To trim or replace the pressure of the spring.
