Opening buffer electric disassembly tooling

Abstract

The invention relates to an electric dismounting tool of a separating brake buffer.The electric dismounting tool comprises a rack, a pull rod sleeve and a power supply control cabinet, the rack is provided with a press-fit head which can slide vertically on a vertical plane, the end, connected with the rack, of the press-fit head is driven by an electric mechanism to achieve vertical reciprocating motion, the press-fit head is a barrel body with an opening facing downwards vertically, a notch is formed in the circumferential side of the press-fit head, the central axis of the pull rod sleeve is provided with a cylindrical hole used for sleeving a piston rod joint of the separating brake buffer therein, the external diameter of the pull rod sleeve is the same as that of a piston rod of the separating brake buffer, and the diameter of the cylindrical hole is greater than the external diameter of the piston rod joint of the separating brake buffer.The electric dismounting tool of the separating brake buffer can be used for dismounting and mounting the separating brake buffer under the circumstance of one-man operation and is simple in structure and convenient to operate, manpower is saved, and meanwhile time is saved.

Description

technical field [0001] The invention relates to an electric disassembly and assembly tooling for an opening buffer. Background technique [0002] When dismantling the opening buffer containing the spring, there is no special tool to dismantle it, and it can only be done manually at present. For example, the opening buffer of the high-voltage circuit breaker whose model is LW35-126W includes a base on which a cylinder and a piston rod located in the cylinder are vertically arranged. The top end of the piston rod is a piston rod joint. The outer circumference of the cylinder is covered with a spring, and the top of the spring is pressed down by a spring pressure plate with a central hole, wherein the central hole of the spring pressure plate passes through the piston rod, and is screwed on the piston rod joint by the fork, and the spring pressure plate is tightened. Limiting, the inner diameter of the central hole of the spring pressure plate is greater than the outer diamete...

AI Technical Summary

Problems solved by technology

In the maintenance process, according to the existing conditions, only relatively simple and cumbersome tools can be used, because the buffer contains a spring, and the spring must be compressed so that the upper fixed clamp fork can be disassembled when it is not stressed. After the disassembly is completed, the compressed spring can be slowly released. In the process of compressing and releasing the spring, two people need to use the ratchet wrench at the same time. This operation is time-consuming and labor-intensive, which is a waste of man-hours and manpower. After the overhaul is completed, the spring and buffer should be reassembled according to the above method
