Description
Technical Field
The invention relates to the technical field of hydraulic braking systems of mining shuttle vehicles, in particular to a novel hydraulic braking system of a shuttle vehicle.
Background
The shuttle car is mainly used in an endless rope continuous tractor system for coal mine auxiliary transportation, is an important component of the endless rope continuous tractor system, and is a tie for realizing the transportation function of the whole system. The main function of the device is to connect a mine car, a flat car, a material car and the like (the above is collectively referred to as a train), and the device is driven by a steel wire rope to carry out reciprocating transportation under the control of a main machine of the endless rope continuous tractor.
Because the shuttle car is suitable for transporting in various roadways, the facing roadway conditions are complex, and the shuttle car is more commonly transported on an uphill slope and a downhill slope. When the shuttle car tractor goes up and down a slope, if the condition that the traction steel wire rope is broken occurs, the endless rope continuous tractor host machine can lose control over the shuttle car and the train, and the shuttle car and the train transported by the shuttle car can rapidly slide down along a track on the slope under the action of gravity. If the situation is not stopped, the speed of the vehicle can be faster and faster until the galloping accident occurs. Therefore, when the condition that the speed is too high due to the fact that the steel wire rope is broken in the ascending and descending transportation is required, the shuttle car can stop and brake in time, and accidents are prevented.
The existing solution is to install the brake cylinder with the clamp brake at the lower part of the shuttle car to realize braking, a spring is installed in the brake cylinder, oil is injected into the cylinder when the shuttle car works normally, so that the clamp brake is opened by compressing the spring, the oil in the cylinder can be released back to the oil tank when the brake is needed, the clamp brake can be reset under the acting force of the spring to tightly clamp the track, so that the brake shuttle car can stop by providing enough braking force, but how to accurately and timely release the oil to realize braking action when the speed of the shuttle car is too high is a difficult problem.
