Replacement operation method for inertial wheel of hydraulic switch machine, and special tool thereof

Abstract

The invention discloses a replacement operation method for an inertial wheel of a hydraulic switch machine, and a special tool thereof. The special tool is used for replacing a screw driver in the prior art for detaching and installing the inertial wheel, and capable of controlling pressure springs at the two sides of the central hole of the inertial wheel simultaneously, so that the pressure springs can be slowly released during detachment and can be slowly pressed during installation; while being detached, the inertial wheel is moved onto the special tool at first, and a pressure is slowly released through the special tool; and when the inertial wheel is installed, the principle is the same, and the steps are opposite. The special tool is capable of pressing the pressure springs to reachspecific positions, and then the inertial wheel is moved onto a motor main shaft, so that the inertial wheel can be rapidly and reliably replaced; remarkable popularization and application effects are achieved; and during night construction of maintenance working personnel, the adverse factors caused due to an environment are overcome, and the construction working efficiency is greatly increased.

Description

technical field [0001] The invention relates to the field of inertial wheels of a hydraulic switch machine, in particular to an operation method for replacing an inertial wheel of a hydraulic switch machine and a special tool thereof. Background technique [0002] The inertia wheel is an indispensable key component in the power system of the ZYJ7 electro-hydraulic switch machine. The function of the inertia wheel is to use its own weight and inertia principle to offset the reverse electromotive force of the three-phase motor after power failure, so as to ensure the normal operation of the switch machine. After locking, the circuit is represented by hooking the switch through the automatic switch. Once the inertia wheel fails, it will cause the motor to reverse after power failure, and the switch machine will be unlocked by mistake after being locked, so that the switch will lose its indication. [0003] ZYJ7 type electro-hydraulic switch machines have a large number, accoun...

Problems solved by technology

However, due to the inability to control the elastic force of the compression spring, this operation step is very difficult, the probability of success is very low, and it is basically impossible for one operator to complete it.

[0006] Based on the above reasons, it is necessary to develop a special tool for disassembling and assembling the inertia wheel and its method to solve the problem of time-consuming and labor-intensive installation.
