Equipment and method for taking out chain pin shaft

Abstract

The present invention provides an apparatus and method for removing a chain pin. The equipment for taking out the chain pin includes a hydraulic system, a base frame support device, and a movable base plate (12), wherein the base frame support device includes a base (1), a base frame lower base plate (2), a support connecting plate (3), The upper base plate (4) of the base frame, the hydraulic system includes a hydraulic cylinder (5), a hydraulic power system (6), a pressure detection device, a pressure protection device and a pipeline, and the movable base plate (12) is provided with a pin corresponding to the chain pin shaft hole (14). When in use, select a movable bottom plate with a suitable aperture according to the size of the chain, place the chain on the movable bottom plate, and use the hydraulic system to press out the chain pin. The invention can quickly dismantle the switch chain pins, improve the efficiency of chain dismantling and maintenance, eliminate the potential safety hazards of manually knocking and dismantling the pins, effectively remove the chain and other chain pins, and have a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of chain maintenance, in particular to a device and method for taking out a chain pin. Background technique [0002] At present, the coke oven hydraulic switch used by Pangang Xichang Steel Vanadium Panjiang Coal Chemical Plant is one of the key auxiliary equipment of the coke oven. There are four coke ovens in Panjiang Coal Chemical Plant of Xichang Iron and Steel Vanadium in Panzhihua Iron and Steel Co., Ltd. Each coke oven has 56 carbonization chambers, and each carbonization chamber corresponds to a gas replacement device. The gas replacement device is connected with the hydraulic exchange line, and the valve of the gas replacement device is kept open and closed through the reciprocating operation of the hydraulic cylinder. Chain connection is used at the corners on both sides of the coke oven to achieve the purpose of pull steering. [0003] However, the overall span of the hydraulic switchboard is la...

AI Technical Summary

Problems solved by technology

[0006] 1. When using hand hammers and copper rods to take out, the knocking time is long, the work efficiency is low, and continuous operation is prone to fatigue, and hand hammers are easy to hit hands and hurt people, which can easily cause safety accidents;

[0007] 2. When heating is used to take it out, the strength of the pin shaft and chain plate will be reduced, resulting in changes in the mechanical properties of the chain, which cannot meet the corresponding working strength requirements
