Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of rail passenger cars, and particularly relates to a grounding switch simulation device. Background Art

[0002] In the past maintenance process of rail passenger cars, after the pantograph fairing on the roof is installed and the vehicle enters the commissioning stage, it is often found that there is an interference between the pantograph fairing and the adjacent grounding switch knife, which affects the operation of the knife switch. The vehicle can only be returned to the assembly stage for secondary adjustment of the fairing. During the adjustment process, due to the differences in individual grounding switches, the installation and positioning dimensions cannot be solidified. When installing the fairing, it is necessary to adjust the fairing on the vehicle according to the position of the knife. The operation of the knife switch needs to be carried out with electricity during the commissioning stage, so it is impossible to verify the interference phenomenon when installing the fairing for the first time. Due to space limitations, it is impossible to use conventional measuring tools such as tape measures for measurement.

[0003] The above-mentioned various reasons will affect the production cycle of the vehicle, increase the maintenance operation man-hours of the vehicle, and increase the vehicle maintenance cost. Summary of the Utility Model

[0004] The utility model aims to solve the technical problems in the prior art and provides a grounding switch simulation device.
