Remote detection system for door closing state of quenching car and detection method thereof

Abstract

The invention provides a remote detection system for the door closing state of a quenching car and a detection method thereof, namely, a simulation system is arranged in an electric locomotive to simulate stretching of door opening and closing cylinders of the quenching car, the flow of a gas circuit is changed by adjusting a pressure regulating valve, so that the two cylinders are synchronously closed, and by detecting a limit switch of the simulation cylinder, the closing of the quenching car door is detected. The limit switch of the device is far away from the quenching car and is in an indoor environment inside the electric locomotive, the working environment is good, the structure is simple, maintenance is convenient, and the problem that the door closing limit switch of the quenching car is damaged due to environmental factors is effectively solved.

Description

technical field [0001] The present invention relates to the technical fields of coke oven mechanical electric locomotive and coke quenching car, and in particular, particularly relates to the detection of the closed state of the coke quenching car. Background technique [0002] The coke oven mechanical quenching car is driven and operated by an electric locomotive on the coke quenching car track on the coke side of the coke oven, picks up the red coke pushed out from the carbonization chamber, transports it to the coke quenching tower for wet coke quenching, and puts the coke quenching The final coke is unloaded on the coke table. When the coke is quenched under the coke quenching tower, a large amount of water will be sprayed on the red coke in the coke quenching car. The temperature of the red coke is about 1000 ℃, and a large amount of water vapor will be generated during the coke quenching process. The existing coke quenching car The door closing limit switch is install...

AI Technical Summary

Problems solved by technology

When the coke is quenched under the coke quenching tower, a large amount of water will be sprayed on the red coke in the coke quenching car. The temperature of the red coke is about 1000 ℃, and a large amount of water vapor will be generated during the coke quenching process. The existing coke quenching car The door closing limit switch is installed on the coke quenching car, which leads to the working environment of the coke quenching car door closing limit switch with very high temperature, high humidity, and very bad working conditions. The service life of the on-site coke quenching car door closing limit switch Extremely short, often damaged, need to be replaced frequently, resulting in economic losses

Damage to the limit switch for closing the door of the coke quenching vehicle can easily cause the driver to drive the vehicle along the track without closing the door of the coke quenching vehicle, resulting in high-temperature red coke falling to the side of the track, causing production accidents, and people on the side of the track , it is likely to endanger the lives of people on the side of the track

The existing problem of damage to the limit switch for closing the door of the coke quenching car has become a difficult problem to be solved urgently
