Underground coal producing hole rail moving type air quantity regulating device

Abstract

The invention discloses an underground coal producing hole rail moving type air quantity regulating device, which comprises a moving rail, an air baffle plate and a pull rod regulating device, wherein the moving rail consists of two identical iron rails; the iron rails are respectively and fixedly arranged at the two sides of a coal producing hole and are mutually parallel; the air baffle plate is arranged between the two iron rails of the moving rail and is attached to the end surface of the coal producing hole; the two sides of the air baffle plate are connected with the moving rail in a slide moving way; the pull rod regulating device comprises a telescopic pull rod and an oil cylinder driving the telescopic pull rod; the output end of the telescopic pull rod is connected with the tail part of the air baffle plate; the air baffle plate is pushed to do reciprocating movement relative to the end surface of the coal producing hole on the moving rail. The underground coal producing hole rail moving type air quantity regulating device has the advantages that through the slide moving air baffle plate, a hole passage of the coal producing hole is covered and plugged; the air leakage risk is effectively reduced; the safety coefficient is improved. The structure is simple; the capital investment is low; the labor and material cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine safety maintenance equipment, in particular to a track-moving air volume adjustment device for an underground coal hole. Background technique [0002] Mine ventilation is one of the most important technical means to ensure mine safety. In the process of mine production, the surface air must be continuously transported to various underground air locations for people to breathe, dilute and eliminate various toxic and harmful gases and mines. dust, create a good environment for underground operations, and ensure the health and labor safety of underground personnel. The ventilation process mainly uses mechanical ventilation (main fan and local fan) as the power to input surface air into the underground, make directional and quantitative flow in the shaft, and finally discharge the dirty air out of the mine; generally, dampers and other facilities are installed in each branch line , Open the damper ...

AI Technical Summary

Problems solved by technology

[0003] There are generally many coal (gangue) outlets underground in coal mines, which are used to quickly discharge coal or gangue blocks. When the coal (gangue) outlets are not delivered, the tunnels are open and a large amount of air leaks, which reduces the intensity of underground ventilation. And it will form a dead angle of ventilation, seriously affecting the safety of underground ventilation

The artificial plugging method is not only time-consuming and laborious, but also needs to open the coal (gangue) hole when it is necessary to discharge coal or gangue, which greatly affects the underground work efficiency.
