Device and method for testing train-tail battery pole pieces

Abstract

The invention discloses a device and a method for testing train-tail battery pole pieces. The device provided by the invention comprises a supporting frame body, a first testing board, a second testing board, a driving unit, a friction time counter, a temperature detector and a testing result output unit, wherein the first testing board and the second testing board are mounted on the supporting frame body; the driving unit is used for driving the first testing board and / or the second testing board to do reciprocating motion so that battery pole pieces to be tested, which are mounted on the first testing board and the second testing board, are rubbed mutually; the friction time counter is used for counting friction times of the battery pole pieces to be tested; the temperature detector is used for detecting the temperatures of the battery pole pieces to be tested; and the testing result output unit is used for outputting the friction times and the temperatures to testing personnel. Compared with the prior art, the wearing resistance and anti-fatigue performance of the train-tail battery pole pieces can be simply and directly tested according to the device and method provided by the invention; and a testing process is simple, and hardware cost needed by a test and manpower consumption are very low.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a device and a method for testing battery pole pieces at the end of a column. Background technique [0002] After the guard (car captain) of the freight train is canceled, the safety protection device at the rear of the train (hereinafter referred to as the train tail host) is widely used as an effective means to control the wind pressure at the train tail. The train tail host is generally installed at the tail of the train and uses a special train tail battery For power supply, in order to facilitate the replacement of the battery at the end of the column, the battery and the host at the end of the column are connected by pole pieces. [0003] During the operation of the train, due to the severe vibration at the rear of the train, the pole piece connecting the main engine and the battery at the end of the train is repeatedly rubbed under strong vibration. At the same time, the host ...

AI Technical Summary

Problems solved by technology

At the same time, the end-of-row host needs to frequently plug and unplug the battery during detection, such as end-of-row library inspection, battery detection, hard restart at the end of the row, etc., constantly plug and unplug the battery at the end of the row, and the plugging action will also cause friction on several pieces

The frequent friction of the pole piece of the battery at the end of the row will cause the wear or break of the pole piece, especially when the host at the end of the column is exposed to sunlight when it is in use, the temperature of the equipment is easy to rise, and the pole piece is more likely to be damaged when it is rubbed at high temperature
