Problems solved by technology

[0003] In the existing underground tunnels of coal mines, the high-pressure air source supply of pneumatic machinery mostly adopts movable gas storage tanks or compressed air equipment or very long air pipes, and the pneumatic machinery is connected by high-pressure pipelines. Since most pneumatic machinery is not fixed when working in the tunnel Sex, the stroke is often large when working, this kind of gas supply facility is extremely inconvenient; more importantly, the pressure in the gas storage tank is not constant pressure, which cannot guarantee the normal operation of pneumatic machinery

Embodiment Construction

[0025] The high-pressure gas source supply mode of existing coal mine underground pneumatic devices mostly uses movable gas storage tanks or very long gas pipes as the gas source. The structure of these gas supply facilities is very inconvenient. However, the long-distance return and release of the trachea is also very inconvenient and safe, and the work efficiency is low and the labor intensity of the workers is very large.

[0026] The present invention aims at the deficiencies existing in the existing gas supply facility structure under the coal mine, and proposes a mine roadway compressed air continuous conveying device, which realizes the continuous supply of high-pressure gas like an electric slide wire, without the need for gas tanks or very long gas pipelines The gas supply is very convenient and fast, and the work efficiency is improved. The specific technical scheme is as follows:

Abstract

Provided is a mine tunnel compressed air sequent conveying device. The mine tunnel compressed air sequent conveying device is composed of a compressed air pipe, a T-shaped sliding rail and an air collection sliding block. The air collection sliding block slides on the T-shaped sliding rail, a sliding block contactor is arranged on the air collection sliding block, a one-way valve is in a closed state when the sliding block contactor on the air collection sliding block does not contact a centre, with slide of the air collection sliding block, the one-way valve is in an open state when the sliding block contactor contacts the centre, and then compressed air enters an air collection cavity, and enters a pneumatic device through an external air pipe connector, and therefore real-time air supply for the pneumatic device is achieved. The mine tunnel compressed air sequent conveying device and the conveying method of the mine tunnel compressed air sequent conveying device achieve the purposes that the compressed air can be continuously supplied as an electric slide wire, an air tank or a long air conveying pipe is unnecessary, and therefore air supply is quick and convenient.

Description

technical field [0001] The invention relates to a compressed air conveying device, in particular to a continuous conveying device for compressed air in a coal mine underground roadway through a compressed air pipeline. Background technique [0002] The underground roadways of coal mines often contain flammable and explosive gases such as gas. It is very dangerous to use gas or electricity as a power source, and it is easy to cause major accidents such as explosions. Therefore, high-pressure compressed gas is generally used as the power source of various equipment in existing coal mine underground roadways, such as pneumatic drilling rigs, pneumatic hoists, etc., to avoid accidents and ensure safe and reliable coal production. [0003] In the existing underground tunnels of coal mines, the high-pressure air source supply of pneumatic machinery mostly adopts movable gas storage tanks or compressed air equipment or very long air pipes, and the pneumatic machinery is connected b...
