Plug uninstalling and fastening wrench for railway locomotive maintenance

Abstract

The invention provides a plug uninstalling and fastening wrench for railway locomotive maintenance. The plug uninstalling and fastening wrench comprises two connecting rods, one end of the connecting rods are clamp handle parts, the other ends of the connecting rods are clamp head parts, the number of the connecting rods is two, the two connecting rods are hinged through a hinge shaft, the clamp head parts have arc-shaped structures, and anti-skid units are arranged on the inner sides of the arc-shaped structures and used for preventing the clamp head parts and a shell of the to-be-uninstalled aviation plug from moving relatively, front-end buckles are arranged at the ends, away from one end of the clamp handle part, of the clamp head parts, and the front-end buckle is used for being inserted into a socket of an inner core of a to-be-uninstalled-installed aviation plug. The plug uninstalling and fastening wrench for the railway locomotive maintenance has the beneficial effects that the plug uninstalling and fastening wrench for the railway locomotive maintenance is simple in force application, more labor is saved compared with manual operation, and the wrench is suitable for a narrow space, and the clamping surface is provided with the insection part made of a hard plastic material, so that the contact friction force is increased on one hand, and on the other hand, the damage to the plug during use is reduced relative to a metal contact surface.

Description

technical field [0001] The invention belongs to the field of maintenance tools for railway locomotives, in particular to a plug disassembly and fastening wrench for maintenance of railway locomotives. Background technique [0002] In the field of locomotive maintenance, it is the most basic requirement for aviation plugs to be fastened and securely connected. If the plugs are not fastened properly, the wiring will be falsely connected, which will easily burn the electrical components of the locomotive, and eventually cause the machine to break. However, in the actual production process, there are many inconveniences: ①Due to oil seepage, aging and wear, poor workmanship, and deviations, a large part of the aviation plugs cannot be easily rotated into place when connected, and a large It takes a lot of strength to rotate and insert it; ②Tightening the plug requires finger force, and some female electricians are weak, unable to tighten the plug, and it is also very laborious t...

Problems solved by technology

[0002] In the field of locomotive maintenance, it is the most basic requirement for aviation plugs to be fastened and securely connected. If the plugs are not fastened in place, the wiring will be falsely connected, which will easily burn the electrical components of the locomotive and eventually cause the machine to break.

However, in the actual production process, there are many inconveniences: ①Due to oil seepage, aging and wear, poor workmanship, and deviations, a large part of the aviation plugs cannot be easily rotated into place when connected, and a large It takes a lot of strength to rotate and insert it; ②Tightening the plug requires finger force, and some female electricians are weak, unable to tighten the plug, and it is also very laborious to disassemble; ③There are many aviation plugs arranged side by side with small gaps between them. If you want to remove the plug in the middle position, you must remove the plug next to it to have room to unscrew the plug in the middle; ④ Some aviation plugs are located in remote places and the space is small. Therefore, a convenient, fast and easy-to-use plug removal method is designed. Tightening pliers are especially necessary
