Tool for dismounting break-brake spring

Abstract

The invention relates to a tool for dismounting a break-brake spring. The tool comprises at least two supporting rods, the supporting rods are used for being fixedly connected with a spring shell of the spring to be dismounted, the axes of the supporting rods extend in the compression direction of a close-brake spring, the supporting rods are sleeved with a compression spring supporting plate capable of moving in the direction of the axes of the supporting rods, the compression spring supporting plate is provided with a bottom face used for jacking and pressing a compression spring plate to compress the break-brake spring and a top face away from the bottom face, a connecting sleeve penetrating hole is formed in the compression spring supporting plate and used for enabling a connecting sleeve on a close-brake spring device to completely penetrate through the compression spring supporting plate from the bottom face of the compression spring supporting plate to the top face of the compression spring supporting plate, and the supporting rods are provided with drive structures used for driving the compression spring supporting plate to move in the compression spring direction and locking structures used for preventing the compression spring supporting plate from moving reversely under the action of the break-brake spring after the compression spring supporting plate moves in place. The tool is simple in structure, convenient to mount and carry and convenient to use, the compression distance of the break-brake spring is not limited, good universality is achieved, and the tool can be suitable for field debugging.

Description

technical field [0001] The invention relates to a tool for disassembly, in particular to a tool for disassembling an opening spring. Background technique [0002] The opening spring device includes the opening buffer and the opening spring assembled together. When the opening buffer needs to be debugged, the opening spring needs to be disassembled first, but the opening spring is an energy storage device, and its elastic force It is relatively large, and it is difficult to disassemble it safely if a special disassembly device is not used. The structure of the tooling used to disassemble the opening spring is currently such as the Chinese patent "Loading and Unloading Circuit Breaker Operation" with the authorized announcement number CN 202285223 U. The structure disclosed in the opening spring tooling of the moving mechanism, the tooling includes a frame body, and the frame body includes a screw nut, and the screw nut is provided with a screw hole for cooperating with the le...

Problems solved by technology

This tool has the following disadvantages: 1) The pressure spring plate is pressed against the compression spring plate by the pressing rod located under the support frame to exert a compressive force on the compression spring plate, and the connecting sleeve will be in the space formed between the support frame and the compression spring plate, so When removing or installing the connecting sleeve part, the support frame, pressure spring plate and pressing rod will interfere with it to a certain extent, which will make disassembly and assembly inconvenient; 2) Since the connecting sleeve is under the support frame, the maximum opening spring The compression distance is limited by the length of the top bar, so the versatility is not good; 3) The structure of the tool is complex, and it is inconvenient to install and carry, which is not conducive to use on the construction site
