A positioning rod 31 is slidably penetrated on the mounting ring 3, and the fixing assembly 5 is used to clamp and fix the extraction pipe 1 and the mounting pipe 4.

[0035] When in use, a hole is drilled on the inner wall of the tunnel in advance, and then the mounting tube 4 is inserted into the extraction hole, and the positioning rod 31 is inserted into the inner wall of the tunnel, so that the mounting tube 4 and the mounting ring 3 can be fixed on the inner wall of the tunnel, and then the extraction tube 1 is inserted into the extraction hole, and the extraction tube 1 and the mounting tube 4 are clamped and fixed by the fixing component 5, and then the mounting plate 2 and the mounting ring 3 are connected, and the extraction tube 1 is fixed and gas extraction can be carried out; the device can prevent the extraction tube 1 from slipping out of the extraction hole by setting the fixing component 5, and is connected with the mounting ring 3 through the mounting plate 2, so that the extraction tube 1 is firmly placed, the fixing effect is good, and the stability of use is improved.

[0036] like Figure 1 and 2 As shown, in this embodiment, the fixing assembly 5 includes a first clamping plate 51, a first spring 52, a second clamping plate 53 and a second spring 54. The front end of the first clamping plate 51 is rotatably disposed on the outer end of the extraction tube 1, and the first spring 52 is pre-stressed between the first clamping plate 51 and the extraction tube 1. The rear end of the second clamping plate 53 is rotatably disposed on the inner end of the mounting tube 4, and the second spring 54 is pre-stressed between the second clamping plate 53 and the mounting tube 4.

[0037] When in use, after fixing the mounting tube 4 and the mounting ring 3 on the inner wall of the tunnel, the extraction tube 1 is inserted into the extraction hole. When the first clamping plate 51 abuts against the second clamping plate 53, the first clamping plate 51 rotates toward the extraction tube 1. At this time, the first spring 52 is compressed, and the second clamping plate 53 rotates toward the mounting tube 4. At this time, the second spring 54 is compressed, and then the extraction tube 1 continues to be pushed to move to the first clamping plate 51 to leave the second clamping plate 53.

[0040] When in use, the rotating rod 65 drives the second bevel gear 64 to rotate, the second bevel gear 64 drives the first bevel gear 63 to rotate, the first bevel gear 63 drives the screw 61 to rotate, the screw 61 drives the threaded sleeve 62 to move, and the threaded sleeve 62 drives the support block 12 to slide along the extraction tube 1 to a suitable position. The support block 12 abuts against the inner wall of the extraction hole, so that the extraction tube 1 is placed firmly, the fixing effect is good, and the stability of use is improved.

[0041] like Figure 3 As shown, in this embodiment, a handle 67 is fixedly provided on the rotating rod 65; the handle 67 facilitates the staff to rotate the rotating rod 65, thereby improving the convenience of use.

[0042] like Figure 1 and 3 As shown, in this embodiment, the mounting plate 2 and the mounting ring 3 are connected by bolts.

[0043] Working principle: When the coal mine gas extraction pipe 1 fixing device provided by the present application is used, a hole is pre-drilled on the inner wall of the tunnel, and then the mounting pipe 4 is inserted into the extraction hole, and the positioning rod 31 is inserted into the inner wall of the tunnel, so that the mounting pipe 4 and the mounting ring 3 can be fixed on the inner wall of the tunnel, and then the extraction pipe 1 is inserted into the extraction hole. When the first clamping plate 51 abuts against the second clamping plate 53, the first clamping plate 51 rotates in the direction close to the extraction pipe 1. At this time, the first spring 52 is compressed, and the second clamping plate 53 rotates in the direction close to the mounting pipe 4. At this time, the second spring 54 is compressed, and then the extraction pipe 1 continues to be pushed to move to the first clamping plate 51 to leave the second clamping plate 53. Under the elastic force of the first spring 52 and the second spring 54, the first clamping plate 51 and the second clamping plate 53 are both compressed. Position, then pull the extraction tube 1 toward the outside of the extraction hole, the first clamping plate 51 will be inserted between the second clamping plate 53 and the mounting tube 4, so that the extraction tube 1 and the mounting tube 4 are clamped and fixed, and the extraction tube 1 cannot be pulled out further, thereby preventing the extraction tube 1 from slipping out of the extraction hole, and then the mounting plate 2 and the mounting ring 3 are connected by bolts, and the extraction tube 1 is fixed and gas extraction work can be carried out; in addition, turning the handle 67 drives the rotating rod 65 to rotate, the rotating rod 65 drives the second bevel gear 64 to rotate, the second bevel gear 64 drives the first bevel gear 63 to rotate, the first bevel gear 63 drives the screw 61 to rotate, the screw 61 drives the screw sleeve 62 to move, and the screw sleeve 62 drives the support block 12 to slide along the extraction tube 1 to a suitable position, and the support block 12 abuts against the inner wall of the extraction hole, so that the extraction tube 1 is placed securely.

[0046] When in use, after fixing the mounting tube 4 and the mounting ring 3 on the inner wall of the tunnel, the extraction tube 1 is inserted into the extraction hole, and the clamping block 56 abuts against the inner wall of the mounting tube 4. At this time, the third spring 57 is compressed, and then the extraction tube 1 continues to be pushed to move until the clamping block 56 leaves the mounting tube 4. Under the elastic force of the third spring 57, the clamping block 56 abuts against the inner wall of the extraction hole, and then the extraction tube 1 is pulled out of the extraction hole. The clamping block 56 will be blocked by the mounting tube 4, so that the extraction tube 1 is clamped and fixed to the mounting tube 4, and the extraction tube 1 cannot be pulled out further, thereby preventing the extraction tube 1 from slipping out of the extraction hole and improving the stability of use.
