Mine safety car arrester device

Abstract

The invention relates to a safety car arrester device for mines. The safety car arrester device for mines comprises a track, a movable groove is arranged on the outer side of the track, a rotating shaft is inserted in the movable groove transversely, and a locking block is arranged in the movable groove, which is connected with a driving plate. Fixed connection, the driving plate is connected to one end of the driving mechanism, the other end of the driving mechanism is connected to the driving rod, and the central control unit is also included. A pressure sensor is set on the track to detect the weight of the mine car to enter the auxiliary shaft. The angle sensor and the central control unit are respectively connected with the pressure sensor and the driving mechanism to control the rotation angle of the rotating shaft by controlling the driving mechanism according to the weight detected by the pressure sensor; the central control unit is provided with a rotation angle matrix, so that precise angle control can be adopted , to achieve precise control of the height of the bump protruding from the track, to achieve precise blocking of mine cars of different qualities, to effectively save the angle of the drive shaft of the drive mechanism, and to facilitate rapid blocking and rapid unblocking.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a mine safety vehicle arrester device. Background technique [0002] At present, due to the long mining time in most mines, the production system is relatively complicated, and there are many operators. There are more than 1,000 people who go up and down the auxiliary shaft every day. With the rapid development of coal mine production and the promotion and application of technology, mining equipment continues to develop in the direction of mechanization, large-scale and automation. Materials have to go up and down from the auxiliary wellhead, and the original casing at the auxiliary wellhead has restricted the lowering of super-long materials. Due to the large amount of rock roadway development tasks, a large number of mining vehicles are required for mining. In addition, manual operation of the auxiliary wellhead support tank gate and manual carts are time-consuming, labor-inte...

AI Technical Summary

Problems solved by technology

In order to ensure the production tasks of the mine, sometimes the inspection and maintenance time can only be shortened, which has buried a major safety hazard for the auxiliary shaft lifting

[0003] In the underground transportation system of coal mines and metal mines, the main transportation stone gates in each section are usually connected with the track downhill, and the coal mining working faces and excavation working faces are connected with the stone gates. This method of mine car is easy to make the mine car crash into the safety door under the action of gravity when people cannot control the speed of the car or the brake of the mine car fails when it is waiting for the cage to rise, so there is a defect of poor protection, so Threat to the safety of staff
