Vehicle-mounted steel wire rope dragging device and using method

Abstract

The invention discloses a vehicle-mounted steel wire rope dragging device and a using method. The device is composed of a base plate assembly, a rope frame assembly and a driving assembly, the rope frame assembly is connected to the upper face of the base plate assembly through a cotter pin by means of a pin, the driving assembly is connected with the rope frame assembly through a hanging lug. Thedevice is applied to a vehicle overspeed or stall blocking system and used in cooperation with a ground hooking and pulling facility. The device is simple in structure, high in practicability, easy to modify on a common mining vehicle and good in real-time control over the vehicle speed, generally, the device is started without manual operation and is automatically controlled by an ECU, casualtyaccidents caused by vehicle stall can be effectively reduced, and the system is advanced at present.

Description

technical field [0001] The invention belongs to a vehicle-mounted dragging wire rope device for a mining vehicle in a stalled state. In particular, the device can release the device immediately after the vehicle-mounted controller detects that the vehicle is stalled, so as to drag and decelerate the stalled vehicle. Background technique [0002] Due to the complex environment under the coal mine and the many slopes, mining vehicles are often overloaded when operating underground, and the brakes fail when going downhill or the vehicles cannot be put into gear and slide. Because the vehicle has a heavy load and the slope is long, under the action of the acceleration of gravity, the inertia of the vehicle's motion is increased, which will cause the brakes to fail. In addition, mining vehicles rarely perform maintenance work for a long time, so it often leads to accidents of brake system failure due to lack of regular maintenance. Because there are too many impurities in the br...

AI Technical Summary

Problems solved by technology

Because the vehicle has a heavy load and the slope is long, under the action of gravity acceleration, the inertia of the vehicle's motion is increased, which will cause the brakes to fail.

In addition, mining vehicles rarely perform maintenance work for a long time, so it 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 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.

The stalling of coal mine operating vehicles due to brake failure is one of the main causes of traffic accidents; when driving downhill with a full load, the driver's operation error causes the vehicle to fail to shift gears when going downhill, which is also the main cause of mining vehicle accidents.

[0003] With the large-scale mechanized production of coal enterprises, the transportation mode of rubber-tyred vehicles has the advantages of: simplifying the auxiliary transportation system, significantly reducing the underground staff engaged in auxiliary transportation; realizing one machine with multiple functions, which is convenient for fully mechanized mining face equipment such as hydraulic supports, mining The maintenance of coal machines and conveyors reduces the labor intensity of maintenance workers; it is flexible, easy to operate and safe, especially suitable for auxiliary transportation in multi-branch roadways mined along coal seams, but the safety protection of rubber-tyred vehicles problem never resolved

[0004] Under the condition that the country has strict requirements on the safety of coal production, if an accident occurs in the transportation of rubber-tired vehicles, production will be stopped for a long time, causing huge economic losses to the enterprise
