Problems solved by technology

However, in the process of use, the pressure gauge and spring of the spring pressure test bench for the grounding device of the train shaft end may also have problems such as deviation, deformation, and failure, which will affect the measurement accuracy. Therefore, it is necessary to develop a self-inspection test bench for the spring pressure test bench instrument

Abstract

The invention discloses a self-detecting instrument for a spring pressure testing table of a shaft end grounding device of a passenger train. The self-detecting instrument comprises a digital force meter and a head base. The head base is arranged in front of the digital force meter. A measuring head of the digital force meter penetrates through the head base. When the self-detecting instrument is used for measuring force, the head base is in threaded connection with the testing table. The measuring head of the digital force meter is in butt joint with a sensor contactor of the testing table. The self-detecting instrument is simple in structure, easy to operate and high in precision, and solves the self-detecting problem of the spring pressure testing table of the shaft end grounding device of the passenger train.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to a spring pressure test bench self-inspection instrument for a railway passenger car axle end grounding device. Background technique [0002] The grounding device is an important part of the new railway passenger car grounding system. Its main function is to prevent the current from passing through the passenger car bearings to cause electric corrosion and endanger the driving safety. Therefore, its technical status is directly related to the grounding reliability and operation of the train power system. safety. At present, there are already various detection equipment for grounding devices, such as the Chinese patent application "Spring Pressure Test Bench for Grounding Devices at Train Axle Ends" (application number 201120186895.4), which can realize the simultaneous detection of multiple carbon brush springs for one grounding device, improving the Measure efficie...
