Centrifugal force automatic brake falling braking mine car

Abstract

The invention discloses a centrifugal force automatic brake falling braking mine car, and relates to a braking device only with one wheel refitted and a falling brake arranged on a chassis additionally on an existing mine car. A centrifugal mechanism and a shifting rod ejection device are sealed in the wheel, a brake falling mechanism and a damper brake are arranged in the chassis, and thus the original function of the mine car cannot be affected. The centrifugal mechanism and the shifting rod ejection device only rotate along with the wheel and cannot make movement in the overspeed process, the brake falling mechanism and the damper brake are kept in a locking state, and operation of the mine car cannot be influenced. Centrifugal force starts the ejection mechanism to eject a shifting rod after overspeed, the shifting rod stirs the brake falling mechanism to enable the damper brake to fall by the aid of the inertia force of the mine car, and the damper brake hooks a sleeper and a track bed component or clamps a track to stop. The centrifugal component is symmetrical in shape, the balancing precision is high, the anti-interference performance is good, the response to the speed is accurate and stable, and false operation can be avoided when the mine car suffers from severe impact and shake in the cage entering and exiting process and the cage overturning unloading process. The centrifugal component and the shifting rod component are sealed in the wheel, so that dust prevention, water resistance and maintenance are facilitated, standardization manufacturing can be achieved, product quality can be improved, cost can be lowered, and the centrifugal force automatic brake falling braking mine car is suitable for various mine cars.

Description

technical field [0001] The invention relates to the technical field of protective safety for an inclined mine car hoisting a sports car. Background technique [0002] In the hoisting of mine cars in inclined shafts, once the mine car breaks the rope during operation, decouples or accidentally sends the unattached vehicle sports car accident at the wellhead, it will often cause major accidents such as damage to shaft equipment and shaft support and even casualties. It is difficult to eliminate objectively sports car accidents caused by human factors. my country has stipulated special clauses in the "Safety Regulations for Coal Mine" and "Safety Regulations for Metal and Nonmetal Mine", which require the installation of sports car protection devices that can stop vehicles that break the rope or decouple in inclined shafts. At present, the protection methods of sports cars mainly include the following types: [0003] The commonly used method for many years is to install a min...

Problems solved by technology

The problem with this method is that there are many ramps for lifting and transporting in mining and production. In practice, it is impossible to densely install this kind of sports car protection device on all ramps that lift mine cars. Most mines are only installed in important lifting shafts. One or a few such sports car protection devices can only prevent sports car accidents within the interception range, and the mining area with wide distribution, long transportation distance, short service period, and poor working conditions can lift ramps and auxiliary transport lifts. Most of the ramps do not have facilities to prevent sports car accidents

Its limitation is that this method can only be applied on the ramp with the pulling force of the hoisting rope. When the mine car runs on the flat road, it needs a special device to put the brakes away, which is inconvenient to use and is not suitable for application on ordinary mine cars. And this method can't solve the problem of the wellhead mistakenly sending the sports car that is not connected to the vehicle

[0006] In recent years, the Internet has introduced a special mine car that uses centrifugal force to control brake braking when overspeed. The centrifugal mechanism is set on the frame, and the brake brake is driven by power. The mechanism is relatively complicated and is not suitable for ordinary mine cars. application

[0007] To sum up, at present, there is no technical measure that can comprehensively prevent all sports car accidents in mines. Preventing major sports car accidents has always been an important issue that needs to be solved urgently in safe production
