Railway train pantograph device capable of automatically adjusting pantograph-catenary contact pressure

Abstract

The invention discloses a rail train pantograph device capable of automatically adjusting pantograph-catenary contact pressure. The rail train pantograph device comprises a base, and a driving mechanism, a sliding mechanism and a lifting mechanism are arranged above the base; the contact pressure is adjusted in time through the driving mechanism, a maintainer does not need to climb on the roof of the rail train to manually measure and adjust the contact pressure between pantographs and catenaries after stopping, the labor cost is saved, the personal safety of the maintainer is protected, the complexity of measurement and adjustment is reduced, and the working efficiency is improved. It is guaranteed that the contact pressure between pantographs and catenaries in the running process of a train is always within a reasonable range, the situation of pantograph current collection faults caused by abnormal contact pressure due to the fact that a roadbed is not smooth, the catenaries change in height and the like in the running process is reduced, and abnormal abrasion of pantograph components caused by too large contact pressure in the running process is avoided; and the operation accidents of the pantograph catenary are reduced, the safety is high, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to a rail train pantograph device capable of automatically adjusting pantograph-catenary contact pressure. Background technique [0002] Since the beginning of the new century, the development scale and population inflow of my country's cities have continued to increase. Due to its advantages of energy saving, land saving, large transportation capacity, environmental protection and pollution-free, rail transit has increasingly become the preferred public transportation for people to travel. Rail trains are mainly driven by electricity, and the high-voltage electricity of the catenary is introduced into the electrical equipment at the bottom of the train through the pantograph. The size of the contact pressure between the pantograph and the catenary directly affects the flow quality between the pantograph and catenary. Therefore, when the train is running safely, reliab...

Problems solved by technology

This kind of manual measurement and adjustment is not real-time. On the one hand, abnormal conditions cannot be adjusted in time to change the operation fault in real time. On the other hand, manual measurement has large errors and consumes a lot of manpower and material resources. The risk of working at heights and the risk of electric shock, for this reason, a rail train pantograph device that can automatically adjust the pantograph-catenary contact pressure is proposed
