[0037] A stable support device for coal mine drilling, including a support base 1. At the central position of the upper part of the support base 1, a support column 5 is arranged. The support column 5 is a hollow tubular structure. The support column 5 is inserted with an adjusting rod 10 from the upper part. The top of the adjusting rod 10 is fixed with a semi-circular clamping part one 8 and a clamping part two 9 through a connecting bolt 13. Rubber protection pads 15 are arranged on the inner sides of the clamping part one 8 and the clamping part two 9. The top of the clamping part one 8 and the clamping part two 9 are detachably connected as a whole by a locking bolt 14, which is used to provide fixation after clamping the drill pipe. On both sides of the support column 5, retractable auxiliary horizontal support rods 4 are symmetrically arranged. Through the auxiliary horizontal support rods 4 with a telescopic rod structure, it is used for the auxiliary support of the device, further improving the support effect and providing stable fixed support for the drilling machine and the drill pipe.

[0038] Further, an anti-slip pad 2 is arranged at the bottom of the support base 1 to enhance the anti-slip effect of the support base 1.

[0039] In some other embodiments, a plurality of groups of adjustment holes 6 are arranged on the side of the adjusting rod 10. After the adjusting rod 10 is inserted into the inner side of the support column 5, the limit bolt 11 is inserted from the support column 5 into the adjustment holes 6 to achieve limitation. The height of the adjusting rod 10 is adjusted according to the use height of the combined drill pipe, which is convenient for providing an adapted support for the drill pipe and the drilling machine.

[0040] In some other embodiments, mutually matching thread structures 12 are arranged at the end of the adjusting rod 10 and the inner side of the top of the support column 5. The screw connection between the adjusting rod 10 and the support rod 5 can further ensure the connection stability between the adjusting rod 10 and the support column 5 and the stability of the overall support structure.

[0041] In some other embodiments, the clamping part one 8 successively includes a right insertion part one 81, a lower right clamping part 82, a right connecting hinge 83, an upper right clamping part 84 and a right top connecting part 85 from bottom to top. By arranging the right connecting hinge 83 in the middle, the opening and closing angle of the clamping part can be adjusted, so that the fixing requirements of drill pipes with different sizes and specifications can be adapted.

[0042] Further, the clamping part two 9 successively includes a left insertion part one 91, a lower left clamping part 92, a left connecting hinge 93, an upper left clamping part 94 and a left top connecting part 95 from bottom to top. By arranging the left connecting hinge 93 in the middle, the opening and closing angle of the clamping part can be adjusted, so that the fixing requirements of drill pipes with different sizes and specifications can be adapted.

[0043] In some other embodiments, the first clamping part 8 and the second clamping part 9 are respectively inserted into the top surface of the adjusting rod 10 through the right insertion part 81 and the left insertion part 91, and the side surface of the adjusting rod 10 is fixed by a connecting bolt 13 passing through the adjusting rod. The locking bolt 14 locks and fixes the right top connecting part 85 and the left top connecting part 95 to ensure the stability of clamping the drill pipe.

[0044] In some other embodiments, the end of the auxiliary horizontal support rod 4 is connected to the support pad 3. The support pad 3 cooperates with the retractable auxiliary horizontal support rod 4 so that it can be connected to the inner wall of the side of the drill hole, playing a role of auxiliary support.

[0045] In some other embodiments, a hand-held adjustment ring 7 is arranged on the outer periphery of the upper part of the adjusting rod 10, which is convenient for holding by hand to control the adjusting rod 10.

[0046] As Figure 4 shown, in some other embodiments, a number of metal reinforcing ribs 16 penetrate through the support base 1, and the rigidity and toughness of the support base 1 are improved by the reinforcing ribs 16.

[0047] Working principle:

[0048] When the stable support device of the present utility model is working, first place the base at a suitable position. The anti-slip pad 2 at the bottom of the base can increase the friction with the ground and prevent the device from sliding during the working process. The support column 5 provides the main support force for the whole device. The height of the fixing frame can be adjusted according to the height of the drill hole equipment and the actual working requirements through the adjustment of the adjusting rod 10.

[0049] When it is necessary to fix the drill hole equipment, open the first clamping part 8 and the second clamping part 9 at the upper end of the adjusting rod 10, place the drill hole equipment between the first clamping part 8 and the second clamping part 9, and then lock and fix it through the locking bolt 14. When the drill pipe has a large size or diameter, the first clamping part 8 and the second clamping part 9 can be manually opened, as Figure 3 shown, to expand the opening angle between the first clamping part 8 and the second clamping part 9 for easy clamping and fixing of the drill pipe. At the same time, the rubber pads on the inner sides of the first clamping part 8 and the second clamping part 9 can, on the one hand, increase the friction with the drill hole equipment to make the fixation more firm; on the other hand, when the drill hole equipment generates vibration during work, the rubber pads can play a certain buffering role to reduce the damage of the vibration to the device and the drill hole equipment.

[0050] During the drill hole operation process, the device provides stable support for the drill hole equipment through the synergistic effect of the support base 1, the support column 5, the adjusting rod 10 and the clamping structure, reduces the shaking of the equipment, and thus improves the drilling accuracy and efficiency.

[0051] The beneficial effects of the stable support device for coal mine drilling holes of the present utility model are as follows: improving operation safety, the stable support device can ensure the stability of the drill pipe and the drilling hole during the coal mine drilling operation, reduce the occurrence of accidents caused by shaking or displacement, protect the lives of the staff, reduce the risk of drilling hole collapse, and prevent dangerous situations such as coal block dropping caused by unstable drilling holes. Improving the drilling quality, accurately controlling the position and direction of the drilling hole, making the drilling hole more regular, improving the accuracy and quality of the drilling hole, reducing the drilling deviation, and ensuring the smooth progress of subsequent mining or other operations. Improving work efficiency, the stable support for the drilling hole can reduce the time wasted by operations such as adjusting the position of the drill pipe, improve the speed of the drilling operation, reduce the failure rate and maintenance times of the equipment, ensure the continuity of work, and thus improve the overall work efficiency. Adapting to different working conditions, this support structure has good adjustability and can adapt to drilling holes of different sizes and different coal mine geological conditions. In a complex coal mine environment, it can still maintain a good support effect, enhancing the versatility and practicability of the equipment.
