Description

Technical Field

[0001] The invention relates to the technical field of grouting and sealing holes, in particular to a grouting and sealing hole device capable of automatically absorbing materials. Background Art

[0002] When extracting gas, it is necessary to drill a hole first and then grout the hole to seal it, so as to facilitate extraction and avoid gas leakage. The existing grouting and sealing device is generally a bag-type grouting and sealing device. When in use, it is sealed and fixed on the extraction pipe, and then enters the borehole with the extraction pipe. When it reaches the sealing position, grouting is performed by a grouting pump to expand the bag to seal the hole. However, when the bag enters the borehole with the extraction pipe, the bag will sag due to the existence of a horizontal section of the borehole, which will cause friction with the borehole wall during movement, easily causing damage, and the inner wall of the borehole will be uneven, causing the bag to break when it expands, affecting the sealing operation.

[0003] In view of the above problems, the present invention provides a grouting and sealing device capable of automatically absorbing materials to solve the above problems. Summary of the Invention

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a grouting and sealing device capable of automatically absorbing material, comprising a drill hole opened at a location to be mined, and further comprising:

[0005] At least two sealing rings are pre-placed in the drilled hole;

[0006] a bladder bag, fixed between the two sealing rings;

[0007] an extraction pipe, penetrating and eccentrically installed in the sealing ring;

[0008] A grouting pipe, connected to the sealing ring;

[0009] a drive assembly fixed to one side of the sealing ring located in the drilling direction;

[0010] a transmission assembly mounted on a side of the drive assembly close to the sealing ring, and

[0011] The leveling assembly is installed on a side of the transmission assembly away from the driving assembly.

[0012] Furthermore, preferably, an air extraction hole is provided on the sealing ring near the drilling entrance for extracting the air inside the bag.

[0013] Furthermore, preferably, a positioning groove is provided in the middle of the bladder, and a pressure valve is installed on the positioning groove. When the bladder is filled with slurry, grouting is continued inward to allow the slurry to flow out of the pressure valve and fill and position the positioning groove.

[0014] Furthermore, preferably, the driving assembly includes:

[0015] Fixed bin with multiple adjustment slots on the circumference;

[0016] a sliding block, symmetrically and slidably arranged in the adjusting slot, and a pressing spring is arranged between the sliding block and the adjusting slot;

[0017] A roller, rotatably arranged between the two sliding blocks using a rotating shaft and located in the adjusting slot;

[0018] a first bevel gear fixed on the rotating shaft;

[0019] An L-shaped connecting plate, one end of which is rotatably arranged on one side of the sliding block and sleeved on the rotating shaft;

[0020] A telescopic shaft, the telescopic end of which is rotatably arranged at the other end of the L-shaped connecting plate;

[0021] A second bevel gear is fixed to the telescopic end of the telescopic shaft and meshes with the first bevel gear for transmission; and

[0022] The transmission shaft is rotatably arranged on the fixed bin, and one end of the transmission shaft is hinged to the telescopic shaft.

[0023] Further, preferably, the transmission assembly includes a driven gear and a driving gear, wherein the driven gear is rotatably arranged on the fixed bin, and the driving gear is fixed to the other end of the transmission shaft and meshes with the driven gear.

[0024] Furthermore, preferably, the leveling assembly includes:

[0025] A rotating ring is fixed on the driven gear and is coaxially sleeved with the sealing ring;

[0026] A plurality of leveling plates are arranged around the circumference, one end of which is hinged to the outer wall of the rotating ring; and

[0027] The guide column is an arc-shaped column, one end of which is slidably arranged in the rotating ring, and the other end is fixed on the screed plate, and an extrusion spring is arranged between the guide column and the rotating ring.

[0028] Furthermore, preferably, the screed plate is made of a deformable material, and is provided with an arc-shaped guide surface on a side close to the transmission assembly to facilitate entry into the drilling hole.

[0029] Compared with the prior art, the present invention provides a grouting and sealing device capable of automatically absorbing material, which has the following beneficial effects:

[0030] In the present invention, after the bag is installed, air can be evacuated from the inside of the bag through the air extraction hole on the sealing ring, so that the bag fits the extraction tube and avoids sagging of the bag during movement. When moving in the borehole, the driving component can contact the inner wall of the borehole, thereby causing the roller to rotate and the flat plate to rotate through the transmission component, thereby leveling the inner wall of the borehole, greatly improving the flatness of the inner wall of the borehole and avoiding damage to the bag. After reaching the sealing position, the grouting pipe can be directly placed in the slurry. At this time, the air pressure inside the bag is lower than the external air pressure, so that the bag automatically absorbs the material first and performs preliminary grouting, reducing the use time of the grouting pump. When the bag no longer automatically absorbs the material, the grouting pipe is connected to the grouting pump for secondary grouting. When the bag is fully expanded, grouting continues until the grouting pressure is greater than the starting value of the pressure valve, so that the slurry flows from the pressure valve into the positioning groove for grouting, thereby improving the stability of the sealing.

[0035] Reference Figures 1 to 3 The present invention provides a technical solution: a grouting and sealing device capable of automatically absorbing material, comprising a borehole 1 opened at a location to be mined, characterized in that it also includes:

[0036] At least two sealing rings 2 are pre-placed in the borehole 1;

[0037] The bag 3 is fixed between the two sealing rings 2;

[0038] The extraction pipe 4 is installed through and eccentrically in the sealing ring 2;

[0039] A grouting pipe 5, connected to the sealing ring 2;

[0040] A driving assembly 6 is fixed to one side of the sealing ring 2 in the drilling direction;

[0041] The transmission assembly 7 is installed on the side of the drive assembly 6 close to the sealing ring 2, and

[0042] The leveling assembly 8 is installed on a side of the transmission assembly 7 away from the driving assembly 6 .

[0043] In this embodiment, an air extraction hole 21 is provided on the sealing ring 2 near the entrance of the drill hole 1 for extracting the air inside the bag 3 .

[0044] It should be noted that after the bag 3 is installed, it is necessary to evacuate the inside of the bag 3 through the exhaust hole 21 so that the bag 3 fits the extraction tube 4 to avoid the bag 3 sagging and causing friction with the inner wall of the borehole 1 during movement.

[0045] In this embodiment, a positioning groove 31 is opened in the middle position of the bladder 3, and a pressure valve 32 is installed on the positioning groove 31. When the bladder 3 is filled with slurry, slurry is continued to be injected inwardly, so that the slurry flows out from the pressure valve 32 and the positioning groove 31 is filled and positioned.

[0046] That is, when the bag 3 is fully expanded, grouting is continued until the grouting pressure is greater than the starting value of the pressure valve 32, so that the slurry flows from the pressure valve 32 into the positioning groove 31 for grouting, thereby improving the stability of the sealing hole.

[0047] In this embodiment, the driving assembly 6 includes:

[0048] The fixed bin 61 has a plurality of adjustment slots on its circumference;

[0049] The sliding block 62 is symmetrically slidably disposed in the adjusting slot, and a pressing spring is disposed between the sliding block 62 and the adjusting slot;

[0050] The roller 63 is rotatably disposed between the two sliding blocks 62 using a rotating shaft 64 and is located in the adjusting slot;

[0051] A first bevel gear 65 is fixed on the rotating shaft 64;

[0052] An L-shaped connecting plate 67, one end of which is rotatably disposed on one side of the sliding block 62 and sleeved on the rotating shaft 64;

[0053] A telescopic shaft 68, the telescopic end of which is rotatably arranged at the other end of the L-shaped connecting plate 67;

[0054] A second bevel gear 66 is fixed to the telescopic end of the telescopic shaft 68 and meshes with the first bevel gear 65 for transmission; and

[0055] The transmission shaft 69 is rotatably disposed on the fixed bin 61 , and one end of the transmission shaft 69 is hinged to the telescopic shaft 68 .

[0056] That is to say, when moving in the borehole 1, the roller 63 can be tightly attached to the inner wall of the borehole 1 through the sliding block 62 and the pressing spring, preventing the roller 63 from rolling against the inner wall of the borehole, and the roller 63 can also guide and support the extraction tube 4, preventing the extraction tube 4 from contacting the inner wall of the borehole 1, thereby causing the extraction tube 4 to be blocked.

[0057] As a preferred embodiment, the transmission assembly 7 includes a driven gear 71 and a driving gear 72, wherein the driven gear 71 is rotatably set on the fixed bin 61, and the driving gear 72 is fixed at the other end of the transmission shaft 69 and meshes with the driven gear 71.

[0058] That is to say, when the roller 63 rotates, the rotating shaft drives the first bevel gear 65 to rotate, thereby rotating the second bevel gear 66 engaged with the first bevel gear 65, and rotating the driving gear 72 synchronously through the hinged transmission shaft 69 and the telescopic shaft 68, and finally drives the driven gear 71 to rotate, and when the roller 63 fluctuates due to the inner wall of the drill hole 1, the second bevel gear 66 can rotate relatively through the L-shaped connecting plate 67. At this time, the telescopic shaft 68 is telescopically adjusted and rotates at the hinged position with the transmission shaft 69, thereby smoothly transmitting the power and improving the stability of the device.

[0059] As a preferred embodiment, the leveling assembly 8 includes:

[0060] The rotating ring 81 is fixed on the driven gear 71 and is coaxially sleeved with the sealing ring 2;

[0061] There are multiple leveling plates 82 arranged around the circumference, one end of which is hinged to the outer wall of the rotating ring 81; and

[0062] The guide column 83 is an arc-shaped column, one end of which is slidably disposed in the rotating ring 81 and the other end is fixed on the screed plate 82 , and an extrusion spring is disposed between the guide column 83 and the rotating ring 81 .

[0063] As a preferred embodiment, the screed plate 82 is made of a deformable material and is provided with an arc-shaped guide surface on a side close to the transmission assembly 7 to facilitate entry into the drill hole 1 .

[0064] Specifically, after the bag 3 is installed, the air inside the bag 3 can be evacuated through the air extraction hole 21 on the sealing ring 2, so that the bag 3 fits the extraction tube 4 to avoid the bag 3 sagging during movement. When moving in the borehole 1, the driving component 6 can contact the inner wall of the borehole 1, thereby rotating the roller 63 and rotating the leveling plate 82 through the transmission component 7, thereby leveling the inner wall of the borehole 1, greatly improving the flatness of the inner wall of the borehole 1, avoiding damage to the bag 3, and reaching the sealing position. The grouting tube 5 can be directly placed in the slurry. At this time, the air pressure inside the bag 3 is lower than the external air pressure, so that the bag 3 automatically absorbs the material first and performs preliminary grouting, reducing the use time of the grouting pump. When the bag 3 no longer automatically absorbs the material, the grouting tube 5 is connected to the grouting pump for secondary grouting. When the bag 3 is fully expanded, grouting is continued until the grouting pressure is greater than the starting value of the pressure valve 32, so that the slurry flows from the pressure valve 32 into the positioning groove 31 for grouting, thereby improving the stability of the sealing hole.

[0065] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
