Automatic anti-running device for mine car

Abstract

The invention discloses an automatic anti-running device for a mine car. The automatic anti-running device comprises a monitoring device, a brake switch, an alarm device and a brake device, wherein the brake switch is connected with a programming controller through a control circuit; the brake switch is electrically connected with the alarm device and the brake device; when the monitoring device detects that the current exceeds a set value, the programming controller closes the brake switch to start the alarm device and the brake device; and the brake device comprises an electromagnet, the electromagnet is installed in a groove between a wheel core and a wheel hub of a wheel, and the input end of the electromagnet is electrically connected with the output end of a battery. The automatic anti-running device has the characteristics of real-time monitoring, automatic alarm and automatic braking, magnetic braking is utilized meanwhile, the phenomenon of friction loss does not exists, kinetic energy of mine car operation is converted into electric energy for storage and use, and therefore energy is saved and green and environment-friendly are achieved.

Description

technical field [0001] The invention relates to the technical field of mining vehicles, in particular to an automatic anti-running device for mining vehicles. Background technique [0002] A mine car is a narrow-gauge railway transport vehicle used to transport bulk materials such as coal, ore, and waste rock. It is the main transportation equipment for mine production. Economic benefits are closely linked with safety. At present, in the production and transportation of coal in China, mine cars are used to transport coal in both horizontal and inclined roads. In the production and transportation, accidents of sports cars caused by mine car breakage, broken chains, broken ropes, etc. occur from time to time. The speed of the mine cart is uncontrollable. Sometimes the mine cart will fall off the track and collide with other mine carts or equipment due to the speed of the mine cart. When it arrives at the designated place, it will be damaged due to excessive speed collision, a...

Problems solved by technology

At present, in the production and transportation of coal in China, mine cars are used to transport coal in both horizontal and inclined roads. In the production and transportation, accidents of sports cars caused by mine car breakage, broken chains, broken ropes, etc. occur from time to time. The speed of the mine cart is uncontrollable. Sometimes the mine cart will fall off the track and collide with other mine carts or equipment due to the speed of the mine cart. When it arrives at the designated place, it will be damaged due to excessive speed collision, and sometimes there will be accidents where the car damages people , has seriously affected the improvement of safety production and economic benefits

[0003] Because the mine car needs extremely high safety and controllability during use, when the mine car has a sports car accident such as a broken rope, unhooked car return, etc., it will seriously endanger the safety of production. Therefore, the mine car needs to be braked urgently. To avoid loss and injury, the current anti-running mine car not only has poor braking performance, but also most of the anti-running devices need to rely on friction to brake the mine car to move forward. Friction is likely to cause aging of the device and requires frequent replacement and maintenance. Time-consuming and labor-intensive, if the replacement is not timely, there will be a greater safety hazard
