Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a gas extraction and sealing machine with a positioning function. Background Art

[0002] At present, in coal mine production activities, it is necessary to measure the coal seam gas pressure and extract gas during the mining process of the coal seam. The quality of borehole sealing directly affects the effect of gas pressure measurement and gas extraction, and most boreholes are sealed with a sealing machine. For example, a sealing machine for a tunnel gas extraction project with a publication number of "CN218862583U" is used. By placing a shaft cylinder inside the borehole, under the action of a spring, the spring drives the slider to slide and adjust in the slide groove. Under the action of a connecting rod, the slider drives the rotating rod to rotate and adjust, so that the rotating rod drives the clamping block to rotate and adjust, so that one side surface of the clamping block fits with the inner wall of the borehole. Under the action of the clamping block, the shaft cylinder is fixed between the inner walls of the borehole, so that the position of the bag is fixed, and the position deviation of the bag is avoided;

[0003] When the above mechanism is in use, the bag is placed on the inner wall of the borehole, and then grout is injected into the bag so that the bag is propped up and fixed on the inner wall of the borehole to achieve the purpose of sealing the hole. However, the lack of positioning function makes the bag placed on the inner wall of the borehole prone to displacement, resulting in a certain gap between the bag and the borehole during grouting, which in turn makes the sealing effect of the borehole poor.

[0004] Therefore, we proposed a gas extraction and sealing machine with positioning function which can solve the above problems well. Utility Model Content

[0032] Embodiment 1: In order to solve the problem that the prior art lacks a positioning function, so that the bag 10 placed on the inner wall of the borehole is easily offset, resulting in a certain gap between the bag 10 and the borehole during grouting, and then the plugging effect of the borehole is poor, the following solution is disclosed, and specific reference is made to Figure 1 and Figure 3-Figure 5 As shown, it includes a base 1 and a support column 14, a motor 2 is bolted to the left side of the upper surface of the base 1, a bearing box 3 is installed in the middle position of the upper surface of the base 1, a barrel 4 is fixed on the top of the bearing box 3, a feed pipe 5 is installed on the right side of the upper surface of the base 1, and a connecting pipe 8 is fixed between the feed pipe 5 and the barrel 4;

[0033] It also includes: the output end of the motor 2 is fixedly installed in the bearing box 3, and the right side of the bearing box 3 is fixedly connected to the left end of the feed pipe 5, the outer side of the middle part of the support column 14 is provided with a bag 10, and a guide pipe 9 is fixed between the bag 10 and the feed pipe 5, and the outer sides of the two ends of the support column 14 are respectively provided with a first positioning plate 11 and a second positioning plate 20, and the first positioning plate 11 and the support column 14 are connected by a movable rod 13, and the two ends of the movable rod 13 are hingedly connected to the side of the first positioning plate 11 and the outer side of the support column 14, and the four first positioning plates 11 are evenly spaced and distributed on the upper and lower sides of the support column 14. A vortex spring 15 is installed at the connection position between the shaft end of the movable rod 13 and the support column 14, and a fitting block 12 is fixed on the side of the first positioning plate 11 between the two movable rods 13. A threaded rod 16 is rotatably connected inside the support column 14, and guide plates 17 are sleeved on the outer sides of both ends of the threaded rod 16. The guide plate 17 and the threaded rod 16 are threadedly connected, and the front side of the guide plate 17 is slidably connected to the inner wall of the support column 14. The positions of the fitting block 12 and the guide plate 17 correspond, and the ends of the fitting block 12 and the guide plate 17 are inclined, and the fitting block 12 fits with the inclined surface of the guide plate 17;

[0034] When in use, the staff inserts the support column 14 into the drill hole, and then the staff manually rotates the threaded rod 16 to move the guide plate 17 and squeeze the two fitting blocks 12. At this time, the fitting block 12 is squeezed and moved, and drives the two first positioning plates 11 to move in the opposite direction. At this time, the first positioning plate 11 fits with the inner wall of the drill hole, so that the position of the bag 10 can be fixed to avoid the position of the bag 10 from shifting. Then, the slurry in the barrel 4 enters the feed pipe 5 through the connecting pipe 8, and is transported to the bag 10 from the guide pipe 9. At the same time, the bag 10 is propped up by the slurry and fits with the inner wall of the drill hole to achieve the blocking of the drill hole.

[0036] When the threaded rod 16 rotates, the driving gear 18 rotates and drives the two racks 19 to move in opposite directions, so that the two second positioning plates 20 move and fit with the inner wall of the drilled hole, and cooperate with the first positioning plate 11, which can further improve the stability of the fixation of the sac 10. Then, when the threaded rod 16 is reversed, the driving gear 18 drives the two racks 19 to move relative to each other, and resets the two second positioning plates 20. Then, through the set check valve 21, the slurry in the barrel 4 only enters the sac 10 from the guide pipe 9, preventing the slurry in the sac 10 from flowing back.

[0037] Embodiment 3: Different from Embodiment 1 and Embodiment 2, this embodiment uses a motor 7 to drive the stirring rod 6 to rotate, which can prevent the slurry in the barrel 4 from solidifying.
