Description

Technical Field

[0001] The invention relates to the technical field of gas hole sealers, in particular to a stable and anti-shaking gas hole sealer. Background Art

[0002] Gas in coal seams is used as a clean energy source. It produces fewer pollutants after combustion and has a higher calorific value. It is a high-quality and clean gas energy that can be used. Through reasonable development and utilization, gas can be converted into electricity or directly used for industrial and civil gas. However, it is also a dangerous hidden danger. When gas accumulates in a mine to a certain concentration, it is very easy to cause an explosion when encountering a fire source, posing a huge threat to the lives and property of miners. In order to ensure the normal mining of coal mines, it is necessary to depressurize and seal the gas in the coal seams.

[0003] When using the existing gas hole sealer, for the convenience of operation, the sealing pipe is directly inserted into the drill hole of the coal seam, and then the subsequent operation is carried out. However, when inserting the sealing pipe, due to the complex hole structure in the coal seam and the fact that the sealing pipe has no other supporting and limiting mechanism to support and fix it, it is easy to cause the sealing pipe to shake, which will affect the sealing effect of the coal seam. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention proposes a stable and anti-shaking gas hole sealer to solve the problem that the currently used gas hole sealer is prone to shaking as mentioned in the above background technology.

[0005] In view of this, a stable and anti-swaying gas hole sealer of the present invention comprises a sealing pipe and a bursting valve, wherein a grouting channel and an extraction channel are respectively opened inside the sealing pipe, a first bag and a second bag are respectively installed outside the sealing pipe, and the bursting valve is installed between the first bag and the second bag;

[0006] Fixed blocks are installed at both ends of the blocking tube, a movable block is installed inside the fixed block, one end of the movable block is connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the movable block is connected to a first movable ring via a rotating shaft.

[0007] Preferably, one side of the first movable ring passes through the fixed block and is connected with a screw rod, and the two groups of the first movable rings are connected with a connecting rod passing through the fixed block.

[0008] Preferably, the screw rod is threadedly connected to the fixed block, and the screw rod is connected to the first movable ring via a bearing.

[0009] Preferably, a rubber ring is sleeved on the outer side of the blocking tube, and a second movable ring is provided on one side of the rubber ring.

[0010] Preferably, the inner ring of the second movable ring is connected with a protrusion via a sliding groove, and a push rod is installed on one side of the second movable ring.

[0011] Preferably, the second movable ring forms a sliding structure with the blocking tube through a protrusion, and the protrusion is installed on the outside of the blocking tube.

[0012] Preferably, a first fixing ring is sleeved on the outer side of the push rod, and a telescopic block is penetrated and connected to the outer side of the first fixing ring.

[0013] Preferably, a movable spring is connected between the telescopic block and the first fixed ring, and a first wedge block is connected between the telescopic block and the groove of the first fixed ring.

[0014] Preferably, a second wedge block is installed at one end of the push rod, and a second fixed ring is provided on the side of the rubber ring away from the second movable ring.

[0015] Preferably, the second fixing ring and the first fixing ring are both installed on the outside of the blocking tube.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, when the stable and sway-proof gas hole sealer is in use, the screw is rotated according to the use requirements, so that the screw drives the connecting rod to rotate through the first connecting ring. When the connecting rod rotates, the movable block at the other end is pushed out from the fixed block through the rotating shaft, so that the movable block is connected to the coal seam. At this time, the movable block plays a role of stabilizing support for the sealing pipe, so that the sealing pipe is not prone to shaking. At the same time, with the help of the connecting rod, the movable block in the other group of fixed blocks is also connected to the coal seam, thereby increasing the stability of the sealing. This is the use feature of the stable and sway-proof gas hole sealer.

[0018] 2. In the present invention, when the stable and anti-shaking gas hole sealer is in use, in order to avoid the shaking of the sealing pipe during the construction process, the screw is rotated so that the screw pushes the movable block in the fixed block out of the groove of the fixed block through the first movable ring and the connecting rod. At this time, the sealing pipe is stuck in the coal seam through the movable block, thereby providing stable support for the sealing pipe, making it less likely to shake.

[0019] 3. In the present invention, when it is necessary to increase the sealing effect of the coal seam, it is only necessary to push the push rod in the direction of the second fixed ring, so that the push rod drives the second movable ring to squeeze the rubber ring, causing the rubber ring to be squeezed and deformed. At the same time, the second movable ring is fixed to one side of the rubber ring through the cooperation of the first wedge block and the second wedge block, so that the rubber ring can better seal the gap in the coal seam.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 , Figure 3 and Figure 4 As shown, a stable and anti-swaying gas hole sealer of the present invention comprises a plugging pipe 1 and a bursting valve 6. A grouting channel 2 and an extraction channel 3 are respectively opened inside the plugging pipe 1. A first bag 4 and a second bag 5 are respectively installed on the outside of the plugging pipe 1. The bursting valve 6 is installed between the first bag 4 and the second bag 5.

[0028] Both ends of the plugging tube 1 are installed with fixed blocks 7, and a movable block 8 is installed inside the fixed block 7. One end of the movable block 8 is connected to a connecting rod 9 through a rotating shaft, and the end of the connecting rod 9 away from the movable block 8 is connected to a first movable ring 10 through a rotating shaft. One side of the first movable ring 10 passes through the fixed block 7 and is connected to a screw rod 11. A connecting rod 12 that passes through the fixed block 7 is connected between the two groups of first movable rings 10. The screw rod 11 is threadedly connected to the fixed block 7. The screw rod 11 is connected to the first movable ring 10 through a bearing, and the movable block 8 forms a sliding structure with the fixed block 7 through a slider.

[0029] During specific implementation, when the present stable and anti-shaking gas hole sealer is in use, in order to avoid the shaking of the sealing tube 1, when the entire sealing tube 1 is inserted into the coal seam, the screw 11 is rotated. Since the screw 11 is connected to the first movable ring 10 through a bearing, and the screw 11 and the fixed block 7 are threadedly connected, rotating the first screw 11 at this time will push the first movable ring 10 to slide along the sealing tube 1, and the first movable ring 10 is connected to the connecting rod 9 through a rotating shaft on the outside, and the other end of the connecting rod 9 is connected to one end of the movable block 8 through a rotating shaft. At this time, rotating the screw 11 will cause the first movable ring 10 to drive the connecting rod 9 to rotate. When the connecting rod 9 rotates, due to the change in angle, it will drive The movable block 8 moves, and the movable block 8 slides in the groove of the fixed block 7 through the slide groove and the slider. Therefore, when the movable block 8 is subjected to the force of the connecting rod 9, it will move outward along the fixed block 7, so that the movable blocks 8 around the fixed block 7 are all moved out of the groove of the fixed block 7 and fit tightly with the coal seam. At the same time, the movement of the movable blocks 8 in one group of fixed blocks 7 will drive the movable blocks 8 in another group of fixed blocks 7 to move out of the groove of the fixed block 7 through the connecting rod 12. The movable blocks 8 in the fixed blocks 7 at both ends of the plugging pipe 1 play a role of stabilizing support and fixing the plugging pipe 1, thereby increasing the stability of the plugging pipe 1, making it less likely to shake, and facilitating subsequent construction.

[0030] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when in use, the screw 11 is rotated according to demand, so that the screw 11 pushes the movable block 8 to move through the first movable ring 10 and the connecting rod 9, and pushes the movable block 8 out of the groove of the fixed block 7. At this time, the movable block 8 will be stuck in the coal seam, and the movable blocks 8 in the two groups of fixed blocks 7 will play a role of stabilizing support for the sealing pipe 1, thereby increasing the stability of the sealing pipe 1.

[0031] A rubber ring 13 is sleeved on the outer side of the blocking tube 1, and a second movable ring 14 is arranged on one side of the rubber ring 13. The inner ring of the second movable ring 14 is connected with a protrusion 15 through a sliding groove. A push rod 16 is installed on one side of the second movable ring 14. The second movable ring 14 forms a sliding structure with the blocking tube 1 through the protrusion 15. The protrusion 15 is installed on the outer side of the blocking tube 1. A first fixed ring 17 is sleeved on the outer side of the push rod 16. A telescopic block 18 is penetrated and connected to the outer side of the first fixed ring 17. A movable spring 19 is connected between the telescopic block 18 and the first fixed ring 17. A first wedge block 20 is connected between the telescopic block 18 and the groove of the first fixed ring 17. A second wedge block 21 is installed on one end of the push rod 16. A second fixed ring 22 is arranged on the side of the rubber ring 13 away from the second movable ring 14. The second fixed ring 22 and the first fixed ring 17 are both installed on the outer side of the blocking tube 1. Four groups of push rods 16 are symmetrically installed about the center line of the second movable ring 14.

[0032] During specific implementation, when it is necessary to increase the sealing effect of the plugging pipe 1, the present stable and anti-swaying gas hole sealer only needs to push the push rod 16 in the direction of the first fixed ring 17, so that the push rod 16 drives the second movable ring 14 to move, and the movement of the second movable ring 14 slides along the protrusion 15 on the outer wall of the plugging pipe 1 through the slide groove of the inner ring, so that the second movable ring 14 is more stable during movement, and the second movable ring 14 pushes the rubber ring 13 on one side to move in the direction of the second fixed ring 22 during movement. At this time, the middle rubber ring 13 is squeezed by the second movable ring 14 and the second fixed ring 22, and the rubber ring 13 is deformed and expanded outwards when squeezed, and at this time, the rubber ring 13 plays a role in sealing the gap in the coal seam, thereby increasing the sealing effect of the entire coal seam;

[0033] When the push rod 16 is pushed, the second wedge block 21 at one end of the push rod 16 will move synchronously. Since the ends of the second wedge block 21 and the first wedge block 20 that are close to each other are both inclined structures, when the second wedge block 21 moves toward one side of the first fixing ring 17 along with the push rod 16, the second wedge block 21 squeezes the first wedge block 20 through the inclined surface and pushes the telescopic block 18 toward the outside of the first fixing ring 17. At the same time, the movement of the telescopic block 18 will put the movable spring 19 in a stretched state. When the second wedge block After 21 moves to one side of the first wedge block 20, the second wedge block 21 does not squeeze the first wedge block 20, and then the movable spring 19 will be reset, and drive the first wedge block 20 to shrink into the groove of the first fixed ring 17 through the telescopic block 18. When the first wedge block 20 shrinks into the groove of the first fixed ring 17, the push rod 16 is limited by the second wedge block 21, so that the second movable ring 14 can squeeze the rubber ring 13 more stably, so that the sealing effect of the entire sealing tube 1 is better.

[0034] See also Figure 1 , Figure 2 and Figure 5 It can be seen that when in use, according to the use requirements, the first movable ring 10 is quickly pushed in the direction of the rubber ring 13 by the push rod 16, and with the cooperation of the second fixed ring 22 and the first movable ring 10, the rubber ring 13 is squeezed. The rubber ring 13 is deformed when squeezed, thereby increasing the sealing effect of the coal seam. At the same time, the push rod 16 and the second movable ring 14 are fixed by the first wedge block 20 and the second wedge block 21, thereby increasing the stability of the second movable ring 14.

[0035] To sum up: when the present stable and anti-sway gas hole sealer is in use, the sealing tube 1 is inserted into the coal seam that needs to be sealed according to the use requirements, and at the same time, the gas in the coal seam will be collected from the extraction channel 3 into the gas collecting head at one end of the sealing tube 1, and then the sealing materials are mixed evenly and injected into the first bag 4 and the second bag 5 through the grouting channel 2. After the two bags are filled, the bursting valve 6 will rupture, so that the sealing materials of the first bag 4 and the second bag 5 flow into the coal seam, which then plays a role in sealing the gaps in the coal seam. This is the prior art and will not be elaborated on here. This is the use feature of the stable and anti-sway gas hole sealer. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
