Embodiment Construction

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0032] Such as Figure 1-5 As shown, the rail transit car coupler connector contact resistance detection auxiliary tooling provided by the present invention has a simple structure, a scientific and reasonable design, and is easy to use. Less, and no thread structure, use movable pins to directly insert and pull out the base (fixed base, adjustable base), and at the same time use the guiding function of the dovetail-shaped guide column to ensure that only the freedom of longitudinal movement is used when the tooling is applied , Greatly shorten the time of installation and disassembly, it only takes 40s to install and disassemble a pair of fixed contacts and moving contacts, and the efficiency is 4 times higher than before. The present invention includes a mountin...

Abstract

The present invention discloses an auxiliary tool for detecting the contact resistance of a coupler connector of a rail transit vehicle and a use method thereof, in order to solve the problem that inthe prior art, pin installation and disassembly is troublesome, time-consuming, and low in efficiency, and the contact is easy to slip and scratch the surface of the pin. The auxiliary tool for detecting the contact resistance comprises a mounting plate, a fixed base, an adjustable base, a stopper, a fixing bolt, a positioning post, a fixed contact plug-in hole, a mounting plate threaded blind hole, a fixed base threaded through hole, a dovetail slot, a dovetail-shaped guide post, a giving way slot, a stopper through hole, a mounting plate blind hole, a movable contact plug-in hole. The use method mainly comprises: firstly installing the fixed base, the adjustable base and the stopper sequentially on the mounting plate; secondly installing a fixed contact and a movable contact respectivelyon the fixed base and the adjustable base; and moving the stopper to the fixed position to fix the stopper so as to complete the installation, and performing a reverse operation to complete the disassembly. According to the technical scheme of the present invention, the installation and disassembly efficiency of the fixed contact and the movable contact can be effectively improved, and the risk of the contact slipping and scratching the surface of the pin can be reduced.

Description

technical field [0001] The invention relates to an auxiliary tool for detecting contact resistance of a coupler connector of a rail transit vehicle and a use method thereof. Background technique [0002] Rail transit vehicles, especially EMUs / subway head cars, most of the contacts used in the coupler connectors contain movable pins or elastic pins. The contact resistance test is a necessary and key point. When contact resistance detection , the existing auxiliary tooling for contact resistance detection has a complicated disassembly process, and the steps of replacing the pins are cumbersome, which leads to long time-consuming and low efficiency of on-site work. It takes about 160s to install and remove a pair of pins, and the auxiliary detection tooling is basically The outer diameter of the clamping position of the seat is relatively large, which may easily cause the contact of the detection equipment to slip and scratch the surface of the contact pin. [0003] Therefore,...
