[0002] Coal mine gas safety management is a key component of ensuring coal mine operation safety, aiming to prevent accidents such as gas explosions. High-concentration gas is removed in advance through drilling and extraction equipment.

[0003] In the process of extracting coal mine gas through pipelines, water inside the mine tunnel is easily pumped into the pipelines, resulting in poor extraction effect.

[0004] In order to overcome the above-mentioned defects, a Chinese patent of the prior art (publication number: CN219865128U) discloses a coal mine gas extraction pipeline, which sets a suspension structure on the extraction pipe so that the extraction pipe can be hung on the side of the tunnel or the anchor net at the top of the tunnel, thereby lifting the extraction pipe, so that the accumulated water in the tunnel will not be sucked into the extraction process, thereby ensuring the extraction effect of gas. In addition, multiple branch pipes are connected to the main pipe at intervals. As the comprehensive mining working face advances, the branch pipe deep into the goaf can be disconnected and extraction can be carried out through the next branch pipe, without having to worry about the problem of poor extraction effect caused by the collapse of external coal blocks in the extraction pipeline during operation.

[0005] The above-mentioned existing technology uses a hanging structure to suspend the pipeline, thereby preventing the pipeline from drawing water into the interior during the gas extraction process. In actual use, the pipeline inside the mine tunnel needs to be laid along the direction of the mine tunnel, and the existing pipeline is not convenient for branching, resulting in a limited extraction range of each pipeline. Utility Model Content

[0006] The purpose of the present utility model is to provide a coal mine gas safety treatment machine to solve the problem in the above-mentioned background technology that the internal pipelines of the mine tunnel need to be laid along the direction of the mine tunnel, and the existing pipelines are not convenient for branching, resulting in a limited extraction range of each pipeline.

A hoop is fixedly connected to the outside of the end of the four-way pipe, and the two hoop rings fit together, and a connecting hoop is fixedly connected to the outside of the hoop ring.

[0009] Preferably, a notch is provided on one side of the connecting hoop, and connecting blocks are fixedly connected to both ends of the notch of the connecting hoop, and connecting bolts are fixedly connected inside the two connecting blocks.

[0010] Preferably, a mounting block is fixedly connected to the outside of the four-way pipe, and a mounting groove is provided inside the mounting block, and the four-way pipe is fixedly connected to the inside of the mounting groove, and a rotating block is rotatably connected to the top of the mounting block, and the rotating block is fixedly connected to a ring, and a limiting bolt is slidably connected inside.

[0011] Preferably, the outer side of the limiting bolt is threadedly connected to the limiting nut, and the lower end of the limiting bolt and the bottom of the limiting nut are respectively fitted with the bottom and top of the rotating block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This coal mine gas safety treatment machine is designed to install a four-way pipe at a fork inside a mine tunnel. At this time, exhaust pipes in different directions are extended to different forks inside the mine tunnel through multiple ports of the four-way pipe.

[0032] The outer side of the limiting bolt 13 is threadedly connected to the limiting nut 14, and the lower end of the limiting bolt 13 and the bottom of the limiting nut 14 are respectively fitted with the bottom and top of the rotating block 12. The upper end of the limiting bolt 13 is fixedly connected to a clamping ring 15, and the clamping ring 15 is made of elastic metal.

[0033] Sealing rings 17 are fixedly connected to the inner sides of the ends of the cross-tube 16 , and fixing frames 18 are fixedly connected to the inner sides of the ends of the cross-tube 16 , and the sealing rings 17 are located outside the fixing frames 18 .

[0034] A sealing block 19 is provided between the sealing ring 17 and the fixing frame 18 , and a sliding rod 20 is fixedly connected to the middle of the sealing block 19 away from the sealing ring 17 , and the sliding rod 20 is slidably connected to the middle of the fixing frame 18 .

[0035] A spring is fixedly connected between the sealing block 19 and the fixing frame 18 , and the spring is located outside the slide rod 20 , and the side of the sealing block 19 away from the slide rod 20 is in contact with the sealing ring 17 .

[0036] Example 2:

[0037] Based on the first embodiment, the specific working principle is as follows:

[0038] The coal mine gas safety treatment machine first connects the four-way pipe 16 with the connecting pipe 3, and connects the other three ports of the four-way pipe 16 with the exhaust pipe, and the structure of the connection between the four-way pipe 16 and the exhaust pipe is the same as that of the connection between the four-way pipe 16 and the connecting pipe 3. At this time, the device will be in Figure 1In the state shown, the connecting pipe 3 will be the same as the inside of the exhaust pipe. At this time, the four-way pipe 16 is installed inside the mine tunnel through the snap ring 15 at its top. Figure 4 It can be seen that the upper end of the clamping ring 15 is set as an expanded structure, and the clamping ring 15 is set as an elastic material. At this time, the clamping ring 15 is clamped in the crack of the rock wall of the mine tunnel, thereby fixing the mounting block 10 inside the mine tunnel;

[0039] When the limit nut 14 and the top of the rotating block 12 are separated from each other, the limit bolt 13 can slide inside the circular ring on one side of the rotating block 12, and the limit bolt 13 can rotate inside the rotating block 12, thereby adjusting the position of the clamping ring 15 on the top of the rotating block 12. At the same time, the position of the mounting block 10 inside the rotating block 12 moves relative to each other. At this time, the mounting block 10 fixes the four-way pipe 16 inside the mine tunnel through its mutual connection with the inside of the mine tunnel. At this time, the air pump 1 is started to perform the air extraction operation, and then the gas is sucked into the air pump 1 through the exhaust pipe, the four-way pipe 16 and the connecting pipe 3, and the gas inside the air pump 1 is discharged from the mine tunnel through the exhaust pipe 2, thereby achieving safe treatment of the gas;

[0040] The four-way pipe 16 is provided with four ports. By installing the four-way pipe 16 at the bifurcation inside the mine tunnel, the exhaust pipes in different directions are extended to different bifurcations inside the mine tunnel through the multiple ports of the four-way pipe 16. The four-way pipe 16 serves as a node to distribute the exhaust pipes inside each mine tunnel. At the same time, the exhaust pipes are conveniently branched, thereby increasing the exhaust operation area of ​​the exhaust pump 1 and facilitating the laying of the exhaust pipes.

[0041] When the four-way tube 16 and the connecting ring 4 are connected to each other, the push rod 6 inside the connecting ring 4 will contact the sealing block 19, so that the push rod 6 pushes the sealing block 19 to move in the direction of the fixing frame 18, so that the sealing ring 17 and the sealing block 19 are separated from each other, until the hoop ring 5 on the outside of the connecting ring 4 and the hoop ring 5 on the outside of the end of the four-way tube 16 fit together. At this time, the connecting hoop 7 is installed on the outside of the two hoop rings 5, and the two connecting blocks 8 are forced to move closer to each other through the connecting bolts 9, and then the hoop rings 5 ​​are connected to each other to form a whole through the connecting hoop 7, completing the mutual connection between the four-way tube 16 and the exhaust pipe and the connecting pipe 3 respectively. When the four-way tube 16 is separated from the connecting ring 4, the spring will drive the sealing block 19 to approach the sealing ring 17 until it fits together with the sealing ring 17. At this time, the sealing ring 17 and the sealing block 19 will form a sealing structure, so that the end of the four-way tube 16 forms a sealing structure, which facilitates the quick disassembly and assembly of the four-way tube 16 with the exhaust pipe and the connecting pipe 3 respectively.
