A damper anti-collision linkage vehicle stop device for coal mines

Abstract

The invention discloses an air door anti-collision linkage vehicle blocking device for coal mine, and relates to the technical field of coal mine facilities. The problems of poor flexibility, stability and reliability of existing air door anti-collision linkage vehicle blocking operation are solved. According to the key points of the technical scheme, a first blocking plate and a second blocking plate are arranged on the two sides of an air door, the air door is provided with a first driving source, the roadway ground is provided with a second driving source for controlling the first blockingplate to open and close and a third driving source for controlling the second blocking plate to open and close; the side, close to the first blocking plate, of the air door is provided with a sequential delay start unit for controlling the sequential delay start of the second driving source, the first driving source and the third driving source; and the side, close to the second blocking plate, ofthe air door is provided with a reverse sequence delay start unit for controlling the sequential delay start of the third driving source, the first driving source and the second driving source. The effects that a mine car and the staff can pass through the air door flexibly, the influence of the poor signal in the mine on the air door anti-collision linkage car blocking is lowered, and the effectof the opening and closing stability of the air door is enhanced are achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine facilities, and more specifically, relates to a damper anti-collision linkage vehicle stop device for coal mines. Background technique [0002] With the development of auxiliary transportation methods in coal mines, trackless rubber-tyred vehicle auxiliary transportation is widely used in coal mines. It is a relatively convenient auxiliary transportation method for transporting personnel, equipment and materials in mines, and is the main development direction of auxiliary transportation in mines. Our mine mainly realizes auxiliary transportation through trackless rubber-tyred vehicles. The underground transportation system is complicated and the vehicle transportation is frequent. When the underground vehicle passes through the damper, it is easy to damage the damper, causing a short circuit of the underground air flow or insufficient air volume on the working face, destroying the stability and ...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used air door anti-collision protection is mainly realized in the following ways: (1) through the organic combination of the air door and the car arrester, using the principle of air door interlocking, the car arrester and the interlocking device of the air door are linked to form a linkage. When the mine car runs to the range of the damper, it is blocked by the car stopper installed on the track; when there are staff in the roadway and the mine car passes through the damper, the operation of the damper will be complicated and its applicability is poor

(2) Use the signal sensor to detect the driving information of the mine car, and control the opening and closing of the damper according to the detected driving information; but due to the poor signal in the mine, the stability of the signal sensor detection is poor

(3) The start of the damper is controlled by the PLC program, the operation steps of the PLC program control are complicated, and the stability of the opening and closing of the damper is poor
