Embodiment 1

[0036] Example 1: Please refer to Figure 1 to Figure 10 : The present invention proposes a coal mine gas overrun ventilation device for coal mine development, comprising: a mobile frame 1; An air circulation pipe 1031 is respectively provided at both ends of the fixed frame 5, and a mounting pipe 502 is provided on the fixed frame 5, and the connecting air pipe 103 is connected to the mounting pipe 502 of the fixed frame 5 through a double-way pipe; a mounting base 3 is slidably installed on the mounting frame 2 , a ventilation pipe 4 is installed on the installation base 3, the top of the ventilation pipe 4 is connected with the bottom end of the connecting air pipe 103, the front end of the ventilation pipe 4 is provided with a ventilation cavity plate 401, and the air circulation pipe 1031 and the ventilation pipe 4 are respectively installed There is a fan; a driving motor 203 is installed on the mounting frame 2, a first rod body 205 and a second rod body 206 are install...

Embodiment 2

[0047] An arc groove 202 is provided on the mounting frame 2, and a sliding shaft 301 is provided at the bottom end of the mounting base 3. The groove 202 is clamped and installed with balls, and the outer surface of the sliding shaft 301 at the bottom of the mounting base 3 is in contact with the balls, which further improves the smoothness of sliding between the sliding shaft 301 on the mounting base 3 and the arc-shaped groove 202 of the mounting frame 2 of the device. .

Embodiment 3

[0049] A spring telescopic rod is respectively installed on both sides of the bottom end of the mounting frame 2. The spring telescopic rod includes a telescopic sleeve, an elastic part and a telescopic rod. On the mobile frame 1, the telescopic rod is slidably installed inside the telescopic sleeve, and an elastic part is installed in the telescopic sleeve, and the outer end of the elastic part is in contact with the outer end of the telescopic rod, which further improves the support for the movement of the installation frame 2 of the device. stability.

[0050] The specific usage and function of this embodiment: In the present invention, a driving rack 207 is slidably connected in the guide groove body 204, and the circular shaft 2032 at the outer end of the rotating rod 2031 is slidably connected to the connecting groove body 2071 at the outer end of the driving rack 207. The driving motor 203 drives the circular shaft 2032 at the outer end of the rotating rod 2031 to rotat...

Abstract

The invention provides a coal mine gas over-limit ventilation device for coal mining, and relates to the technical field of ventilation devices. A mounting frame is mounted on the moving frame in a sliding manner; a connecting air pipe is arranged at the top end of the moving frame; a mounting base is mounted on the mounting frame in a sliding manner, and a ventilation pipe is mounted on the mounting base; a driving motor is mounted on the mounting frame, a first rod body and a second rod body are rotatably mounted on the mounting frame, and a driving rack is slidably mounted on the mounting frame; a gas detector is mounted at the top end of the ventilation cavity plate; according to the device, the mounting base is matched with the driving rack, and the first rod body and the second rod body are used, so that a ventilation pipe reciprocates up and down while performing fan-shaped reciprocating motion in a coal mine area, and the problem that the efficiency of extracting and ventilating gas in a coal mine by the device is poor due to a single fixed position of the ventilation pipe is solved.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a coal mine gas overrun ventilation device for coal mine development. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants; in a high temperature and high pressure environment, while coal is formed, gas continues to be generated due to physical and chemical effects; gas It is a colorless, odorless gas, hardly soluble in water, does not support combustion and cannot maintain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can burn or explode. [0003] However, as far as the current traditional ventilation device is concerned, the ventilation pipe in the coal mine is fixedly installed, and the single position of the ventilation pipe makes the gas extraction efficiency of the ventilat...
