Mine construction tunnel engineering requires the installation of a ventilation system to provide and improve underground air quality and the working environment. The ventilation system is a general term for mine ventilation methods, ventilation systems, and ventilation networks, mainly including fan control, ventilation ducts, CO sensors, traffic status detection, fire alarm control, and TC control. The working principle of the ventilation system is explained below.

[0003] When constructing mine roadways, ventilation ducts on the inside of the roadway are usually suspended from the arch shoulder or top, while the ventilation fan is generally installed at the mine entrance, a certain distance from the roadway. The ventilation ducts in this area lack dedicated suspension devices, resulting in the ventilation ducts not being installed securely enough.

[0004] Therefore, this utility model proposes a new solution. Utility Model Content

Through the arrangement of the round rod 7, sleeve 8, and clamp 9, the clamp 9 can slide back and forth relative to the round rod 7, thereby adjusting the position of the ventilation duct to ensure its axis is straight. The clamp 9 can also rotate a certain angle relative to the round rod 7, thereby adjusting the angle between the ventilation duct and the horizontal plane, making it suitable for roadways requiring uphill or downhill movement and offering greater flexibility. By setting the first screw hole 10 and the first set bolt 11, after adjusting the position of the sleeve 8, the first set bolt 11 is used for fixation to ensure stable support.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the base frame 5 includes two parallel uprights 501 and a connecting rod 502 connecting the two uprights 501.

With the setting of the buffer mechanism, when the fan 1 is turned on or off, it can buffer and reduce the shock of the air duct, reduce the damage to the air duct, and improve the service life of the air duct.

[0033] In this embodiment, as Figures 1-6 As shown in the figure, the working distance of a ventilation device for mine shaft and tunnel construction provided in this embodiment is as follows:

[0034] Step 1: When using, fix the base frame 5 on the ground, raise and lower the lifting frame 6, and then use the second set bolt 507 to fix it. Then, pass the air duct through the clamp 9.

[0035] Step 2: Adjust and rotate the sleeve 8 according to the roadway conditions, and then use the first set bolt 11 to fix it;

[0036] Step 3: When the fan 1 is turned on, the fan duct vibrates and causes the clamp 9 to vibrate, and the buffer mechanism plays a role in buffering and shock absorption.
