Rail antiskid device for cars of coke oven and antiskid method

Abstract

The invention relates to a rail antiskid device for cars of a coke oven. The rail antiskid device is characterized by comprising driving wheels, driven wheels, driving wheel speed measuring coders, driven wheel speed measuring coders, an automatic cleaning control system, a control line, a water tank water level detecting device, high-pressure pump branch pipes, cleaning solenoid valves and cleaning nozzles, wherein the driving wheel speed measuring coders are arranged on the driving wheels, and the driven driving wheel speed measuring coders are arranged on the driven wheels. The rail antiskid device is compact and simple in structure, and can automatically judge whether rails are polluted or not according to the skid condition of the cars of the coke oven and automatically clean the rails and perform interlock protection to guarantee high-speed and safe operation of four cars of the coke oven.

Description

technical field [0001] The invention relates to an anti-skid device for coke oven locomotive tracks, belonging to the technical field of coke oven control. Background technique [0002] The coke pushing car, coke holding car, coal feeding car and electric locomotive system (referred to as the four major cars) of the coke oven are important equipment in the production of coke ovens, and their operating conditions directly determine the quality and output of coke oven production. The running system of the four major coke oven vehicles is an important link in the production and operation of each vehicle. Heavy-duty, high-speed locomotives run on the track, and need to rely on the friction between the wheels and the track to accelerate and decelerate. Taking the electric locomotive as an example, it includes a power locomotive and two transport vehicles (see figure 1 Side view and top view), the power locomotive drags the 1# carrier car and the 2# carrier car to run at high sp...

AI Technical Summary

Problems solved by technology

Taking the electric locomotive as an example, it includes a power locomotive and two transport vehicles (see figure 1 Side view and top view), the power locomotive drags the 1# carrier car and the 2# carrier car to run at high speed on the track. Since the track is installed in the open air, in the case of rainy and snowy weather and serious track pollution, the The dust on the track is mixed with rain and snow, and the resulting mixture greatly reduces the coefficient of friction between the power wheel and the track in the power locomotive, resulting in the following consequences: the power wheel still rotates at a preset speed during the acceleration phase, due to friction If it is not enough, the wheels will slip on the track, causing the vehicle to start slowly and the car body to vibrate violently; during the deceleration stage, the power wheel still decelerates and rotates according to the preset speed value. Due to insufficient friction, the wheels will slip on the track, resulting in the vehicle not being able to run in time. There are serious potential safety hazards in deceleration; the operator's judgment on the slippage of the vehicle lags behind, and slippage occurs during the deceleration process of the vehicle. At this time, even if the driver finds an abnormality and takes emergency braking measures for manual intervention, it is often too late. Easy to cause locomotive derailment accidents

Because this problem is caused by the sewage mixture on the track, the fundamental method to solve the problem is to ensure that the track is clean. In the prior art, the method of manually cleaning the track or air blowing the track can not judge whether the track needs to be cleaned in time, and The cleaning effect is also not satisfactory, therefore, new technologies are urgently needed to solve the above problems
