[0002] The traditional device closes the pipeline by setting a bladder and injecting slurry into the bladder, so that the bladder expands and then closes the pipeline. Although the effect of pipeline closure is achieved, there are still certain defects. For example, the expansion process of the bladder is relatively random and lacks effective guidance, and after the bladder expands, it completely relies on the slurry to support inside the pipeline, which will affect the sealing performance and stability of the bladder to the pipeline.

[0003] In the prior art, CN214944156U discloses an auxiliary mechanism for plugging reserved pipes in gas control, which includes a bladder arranged inside the pipeline and a grouting pipe connected to the bladder. The bladder is annular, and a support inner ring is arranged inside its inner circle. One end of the grouting pipe extends into the support inner ring to form a slurry outlet section. Multiple groups of slurry inlet pipes are arranged on the surface of the slurry outlet section in a centrosymmetric distribution. The slurry inlet pipes are distributed parallel to the radial direction of the bladder, and the slurry outlet ends of the slurry inlet pipes penetrate through the support inner ring and are communicated with the bladder. The auxiliary mechanism for plugging reserved pipes in gas control of this solution effectively guides the expansion process of the bladder and centrally supports the expanded bladder, improving its sealing performance and stability.

[0004] However, in order to be portable, the existing device usually assembles the grouting pipe and the bladder on-site and then uses them. Operators generally directly butt-insert the grouting pipe into the pipeline connected to the bladder, so that the grouting pipe is easily detached from the pipeline connected to the bladder during the process of injecting slurry.

Detailed Description of the Embodiments

[0019] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0020] The first embodiment of the present application is as follows:

Figure 2 It is a schematic structural diagram of a fixing component according to the first embodiment of the present utility model.

[0022] The utility model provides an auxiliary mechanism for plugging reserved pipes for coal mine gas control, which includes a bladder main body 101, a slurry outlet pipe 102 and a fixing component. The fixing component includes a grouting pipe 103, a connecting bracket 104, a fixing block 105, a clamping bracket 106, a locking bolt 107, a limiting member, a rubber pad 108, a first fixing plate 109, a second fixing plate 110, a traction spring 111, a first fixing seat 112 and a second fixing seat 113. The limiting member includes a sliding bracket 114 and a limiting block 115. Through the foregoing solution, the problem that existing devices are usually assembled on site by docking the grouting pipe and the bladder for portability is solved. Operators generally directly dock and insert the grouting pipe into the pipe connected to the bladder, so that the grouting pipe is likely to come out of the pipe connected to the bladder during the process of injecting slurry. It can be understood that the foregoing solution can be used in cases where the grouting pipe needs to be better connected and fixed to the bladder.

[0023] In this embodiment, the slurry outlet pipe 102 is arranged on the bladder main body 101. The slurry can be introduced into the bladder main body 101 through the slurry outlet pipe 102, so that after the bladder in the bladder main body 101 is formed, its surface can contact the inner wall of the pipe more stably and effectively, so as to improve its pipe sealing performance and stability. The structures of the bladder main body 101 and the slurry outlet pipe 102 and their corresponding connection structures are described in detail in the prior art CN214944156U and will not be elaborated here.

[0024] Among them, the grouting pipe 103 is connected to the slurry outlet pipe 102 and is located on one side of the slurry outlet pipe 102. The connecting bracket 104 is fixedly connected to the slurry outlet pipe 102 and is located on one side of the slurry outlet pipe 102. The fixing block 105 is fixedly connected to the connecting bracket 104 and is located on one side of the connecting bracket 104. The clamping bracket 106 is connected to the fixing block 105 through the limiting member and is located on the side of the fixing block 105 close to the grouting pipe 103. The locking bolt 107 is arranged on the fixing block 105 and abuts against the clamping bracket 106. The limiting member is arranged on the fixing block 105 and is connected to the clamping bracket 106. The grouting pipe 103 is clamped and communicated inside the slurry outlet pipe 102. Through the grouting pipe 103, the slurry can be injected into the bladder main body 101 through the slurry outlet pipe 102. The connecting bracket 104 is welded to the slurry outlet pipe 102. There are two fixing blocks 105, and the two fixing blocks 105 are welded to the connecting bracket 104. There are two clamping brackets 106, and the two clamping brackets 106 are connected to the corresponding two fixing blocks 105 through the limiting member. Through the limiting member, the movement of the clamping bracket 106 can be connected, supported and directionally limited. There are two locking bolts 107, and the two locking bolts 107 are arranged on the corresponding two fixing blocks 105. The fixing block 105 has a threaded hole for cooperating with the locking bolt 107. By turning the locking bolt 107, the locking bolt 107 can be moved to abut against the clamping bracket 106 and push the clamping bracket 106 to move towards the outside of the grouting pipe 103. The limiting member is arranged on the fixing block 105 and is connected to the clamping bracket 106. Through the limiting member, the movement of the clamping bracket 106 can be connected, supported and directionally limited. Thus, when it is necessary to introduce the slurry into the bladder main body 101 connected to the slurry outlet pipe 102, by docking and clamping the grouting pipe 103 into the slurry outlet pipe 102, the slurry can be introduced into the slurry outlet pipe 102 through the grouting pipe 103. At the same time, the operator turns the locking bolt 107, so that the locking bolt 107 moves to abut against the clamping bracket 106 and pushes the clamping bracket 106 to move towards the outside of the grouting pipe 103 to abut. The clamping brackets 106 abutting on both sides of the grouting pipe 103 are used to abut, clamp and fix the movement of the grouting pipe 103, thereby preventing the grouting pipe 103 from being disengaged from the slurry outlet pipe 102 during the process of injecting the slurry.

[0025] Secondly, the sliding bracket 114 is slidably connected to the fixed block 105 and fixedly connected to the clamping bracket 106, and is located on the side of the fixed block 105 close to the clamping bracket 106; the limiting block 115 is fixedly connected to the sliding bracket 114 and is located on the side of the sliding bracket 114 close to the fixed block 105. There are four sliding brackets 114, and the four sliding brackets 114 are slidably connected to the corresponding two fixed blocks 105. The fixed block 105 can connect, support and directionally limit the sliding of the sliding bracket 114. The four sliding brackets 114 are welded to the two clamping brackets 106. By the sliding of the sliding bracket 114, the movement of the clamping bracket 106 can be connected, supported and directionally limited. There are four limiting blocks 115, and the four limiting blocks 115 can prevent the sliding bracket 114 from slipping out when sliding on the fixed block 105.

[0026] Meanwhile, the rubber pad 108 is fixedly connected to the clamping bracket 106 and is located on the side of the clamping bracket 106 close to the grouting pipe 103. There are two rubber pads 108, and the two rubber pads 108 are bonded to the corresponding two clamping brackets 106. The rubber pad 108 can increase the friction force when the clamping bracket 106 clamps and fixes the grouting pipe 103, and further better prevent the grouting pipe 103 from slipping out of the slurry outlet pipe 102 during the grouting process.

[0027] In addition, the first fixing plate 109 is fixedly connected to the fixed block 105 and is located on one side of the fixed block 105; the second fixing plate 110 is fixedly connected to the clamping bracket 106 and is located on one side of the clamping bracket 106; the traction spring 111 is fixedly connected to the first fixing plate 109 and the second fixing plate 110 respectively. The traction spring 111 is located on the side of the first fixing plate 109 close to the second fixing plate 110. There are four first fixing plates 109, and the four first fixing plates 109 are welded to both sides of the two fixed blocks 105. There are four second fixing plates 110, and the four second fixing plates 110 are welded to both sides of the two clamping brackets 106. There are four traction springs 111, and both ends of the four traction springs 111 are welded to the corresponding four first fixing plates 109 and second fixing plates 110 respectively. Through the deformation ability of the traction spring 111 for traction, the two clamping brackets 106 not abutted and pushed by the locking bolt 107 can be pulled apart to both sides, which is convenient for the operator to dock the grouting pipe 103 into the slurry outlet pipe 102.

[0028] Finally, the first fixing seat 112 is fixedly connected to the first fixing plate 109 and the traction spring 111 respectively. The first fixing seat 112 is located on the side of the first fixing plate 109 close to the traction spring 111. The second fixing seat 113 is fixedly connected to the second fixing plate 110 and the traction spring 111 respectively. The second fixing seat 113 is located on the side of the second fixing plate 110 close to the traction spring 111. There are four first fixing seats 112, and the four first fixing seats 112 are welded to the corresponding four first fixing plates 109 and one ends of the four traction springs 111. Through the first fixing seat 112, one end of the traction spring 111 can be more stably connected to the first fixing plate 109. There are four second fixing seats 113, and the four second fixing seats 113 are welded to the corresponding four second fixing plates 110 and the other ends of the four traction springs 111. Through the second fixing seat 113, the other end of the traction spring 111 can be more stably connected to the second fixing plate 110.

[0029] When using the auxiliary mechanism for plugging and reserving pipes for coal mine gas control in this embodiment, when the slurry needs to be introduced into the bladder main body 101 connected to the slurry outlet pipe 102, by docking and engaging the grouting pipe 103 into the slurry outlet pipe 102, the slurry can be introduced into the slurry outlet pipe 102 through the grouting pipe 103. At the same time, the operator twists the locking bolt 107, so that the locking bolt 107 moves to abut against the clamping frame 106, and pushes the clamping frame 106 to move towards the outside of the grouting pipe 103 for abutting. The movement of the grouting pipe 103 is abutted and clamped by the clamping frames 106 abutted on both sides of the grouting pipe 103, so as to prevent the grouting pipe 103 from coming out of the slurry outlet pipe 102 during the process of injecting the slurry.

[0030] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
