A kind of centrifugal force automatic brake mine car

Abstract

A mine car with centrifugal force automatic brake braking, only one wheel is refitted on the existing mine car and a brake brake device is installed on the chassis, the centrifugal mechanism and the lever ejection device are sealed in the wheel, the brake mechanism and The brake is arranged in the chassis, which does not affect the original function of the mine car. When the speed is not exceeded, the centrifugal mechanism and the lever device only rotate with the wheels without action, and the brake mechanism and brake remain locked, which does not affect the operation of the mine car. After overspeed, the centrifugal force activates the ejection mechanism to eject the lever, and the lever borrows the inertia of the mine car to move the brake mechanism to drop the braking brake. The braking brake hangs on the sleeper and ballast bed components or blocks the track to stop. The centrifugal parts have symmetrical shape, high balance precision, good anti-interference, and accurate and stable speed response. The mine car does not malfunction when it enters and exits the cage, overturns and unloads, etc. when violent impacts and shaking occur. Centrifugal and lever parts are sealed in the wheel for dustproof, waterproof and maintenance. It can be manufactured in a standardized way to improve product quality and reduce costs. It is suitable for application on various mining vehicles.

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 provisions in "Safety Regulations for Coal Mine" and "Safety Regulations for Metal and Nonmetal Mine", requiring that a sports car protective device capable of stopping vehicles with broken ropes and decoupling in operation should be installed in inclined shafts and lanes. At present, the protection methods of sports cars mainly include the following types: [0003] The commonly used method for...

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 the ramps for lifting 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

[0006] In recent years, the Internet has introduced a special mine car that uses centrifugal force to control brake brakes 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
