[0002] Underground ventilation is of paramount importance for safe production. In the prior art, the main equipment for underground ventilation or wind flow control is the wind duct, including wind ducts fixed in the tunnel and flexible wind ducts that move with the mining face. Commonly, existing wind ducts usually need to be uniformly arranged with lifting equipment, sliding parts that cooperate with the forward delivery of the wind duct, and power drive parts. However, the position and orientation of the end of the wind duct often need to be flexibly adjusted. The prior art lacks specific technical means for this problem and cannot achieve rapid deployment. Commonly, the forward delivery of the wind duct requires pre-installed brackets, and the assembly process is cumbersome and consumes a lot of manpower and material resources. Especially for wind duct equipment with integrated dust collection for return air, the installation position is very important, and the inability to quickly adjust with the mining face has always been a problem that needs to be solved in this field.

[0015] Reference Figure 1 , Figure 2 The utility model discloses an external wind tube hanging support component, comprising a hoop sleeve 1, wherein the hoop sleeve 1 is used to be sleeved on an anchor rod, and a hard limit screw hole is provided on the side wall of the hoop sleeve 1, and a limit bolt is passed through the hard limit screw hole;

[0016] A connecting rod 2 is fixedly arranged on the side of the hoop 1, and the connecting rod 2 is a sleeve structure;

[0017] The effect achieved by this is to quickly adjust the longitudinal height of the wind tube;

[0018] A wind tube hanging base 4 is arranged at the bottom of the connecting rod 2. The wind tube hanging base 4 is a semicircular frame structure. A wind tube clamp 3 is fixedly arranged on the bottom surface of the wind tube hanging base 4.

[0019] The effect achieved by this is that the device can be quickly assembled to the mining face through the anchor rod. After the device is fixed, the annular hoop frame of the wind tube is clamped by the wind tube clamp 3 to achieve rapid positioning of the wind tube.

[0020] Furthermore, the connecting rod 2 includes a first sleeve 21, and the first sleeve 21 is fixedly arranged on the side of the hoop 1;
