Intercepting device in mining intercepting system and using method

Abstract

The invention discloses an intercepting device in a mining intercepting system and a using method. The intercepting device comprises a ground hook device and a ground hook triggering device. When thetriggering device receives an alarm signal sent by the stall rubber-tyred vehicle, an electromagnet is immediately controlled to act by a control circuit in the device; the electromagnet moves forwards to destroy the balance of the hinge structure, the heavy weight hung on the whole hinge structure falls off, the steel wire rope connected to the heavy object is driven to lift upwards, the other end of the steel wire rope drives the pin triggering the ground hook to transversely move to release the ground hook, the ground hook is popped up from the ground by the spring, therefore, the draggingsteel wire rope on the stall mining vehicle can be hung on the ground hook in time, the steel wire rope on the ground hook depends on the braking force generated by the automatic torque increasing device, then the force is amplified through the steel wire rope buffer to drag the vehicle, the vehicle is stopped within a short time, and the purpose of protecting the stall mining vehicle is achieved.

Description

technical field [0001] The invention belongs to the field of mine arresting systems, and in particular relates to an intercepting device in a mine arresting system and a usage method thereof. Background technique [0002] Mining vehicles operating underground in coal mines are often overloaded. Due to severe overloading, under the action of gravity acceleration, the vehicle's motion inertia is relatively large, which may directly lead to brake failure. And when the mining vehicle goes downhill for a long time, the brakes fail or the gear cannot be shifted, causing the vehicle to slide. In addition, mining vehicles rarely perform maintenance work for a long time, which often leads to accidents of brake system failure due to lack of regular maintenance. Because there are too many impurities in the brake pump, the seal is not tight, the brake oil is seriously polluted, etc., after the brake system is heated, there will be oil leakage from the brake pump, air leakage from the g...

Problems solved by technology

[0002] Mining vehicles operating in coal mines are often overloaded. Due to severe overloading, under the action of gravity acceleration, the vehicle's motion inertia is relatively large, which may directly lead to brake failure

And when the mining vehicle goes downhill for a long time, the brakes fail or the gear cannot be shifted, causing the vehicle to slide

In addition, mining vehicles rarely perform maintenance work for a long time, so accidents often result in failure of the brake system due to lack of regular maintenance.

Because there are too many impurities in the brake pump, the seal is not tight, the brake oil is seriously polluted, etc., after the brake system is heated, there will be oil leakage from the brake pump, air leakage from the gas storage tank or the pipeline interface, resulting in brake failure.

It is also one of the main causes of vehicle brake failure due to improper operation of the driver when braking. For example, going downhill for a long time will cause friction and heat of the brake pads, carbonization of the brake hub, and complete failure of the brake function.
