The two ends of the torsion spring are respectively fixedly connected to the opposite sides of the fixed block and the connecting rod.

[0009] Furthermore, a hand-held positioning mechanism is fixedly connected to the front surface and the rear surface of the shrinkage cylinder and above the two connecting heads opposite to each other in the front and rear.

[0010] The hand-held positioning mechanism includes an air cavity two. A piston plate two is slidably connected inside the air cavity two. A spring one is fixedly connected between the piston plate two and the air cavity two. A through hole is formed on the left side of the air cavity two. Two through ventilation holes two are formed on the front surface of the air cavity two. A handle one is arranged in front of the air cavity two. One side of the handle one close to the air cavity two penetrates to the inner side of the air cavity two and is fixedly connected to one side of the piston plate two close to the spring one. The air cavity two and the shrinkage cylinder are fixedly connected to the opposite sides.

[0011] Furthermore, two sealing rings are fixedly connected to the inner side wall of the air cavity two on the outer side wall of the handle one.

[0012] Furthermore, ventilation pipes are respectively fixedly connected between the multiple ventilation holes two and the multiple ventilation holes one.

[0013] Furthermore, a plurality of wedge-shaped bayonets are formed on both sides inside the shrinkage cylinder.

[0014] Further, symmetric air chambers three are provided below the interior of the U-shaped fixing frame. A wedge-shaped piston block is slidably connected inside the air chamber three. A second spring is fixedly connected between the wedge-shaped piston block and the air chamber three. The opposite sides of the two wedge-shaped piston blocks are respectively engaged inside the two wedge-shaped notches located above the interior of the contraction cylinder.

[0015] Further, an air groove is provided on the upper surface inside the air chamber three. An air chamber four is integrally formed at the top of the air groove. A piston block is slidably connected inside the air chamber four. A second handle is provided above the U-shaped fixing frame. The bottom of the second handle extends into the interiors of the two air chambers four respectively and is fixedly connected to the upper surfaces of the two piston blocks respectively.

[0016] Further, a winding wheel is fixedly connected to the top of the dual-axis motor and located above the U-shaped fixing frame. Two traction ropes are fixedly connected to the outer sidewall of the winding wheel. The bottom ends of the traction ropes penetrate into the interior of the contraction cylinder and are fixedly connected to the lower surface inside the contraction cylinder.

[0017] According to another aspect of the present invention, a method for drilling in a hydrogeological and mining geological mine is provided, including the following steps:

[0018] S1. Move the device to the drilling position, make the support rod contact the ground, and press down the device so that the support rod is inclined for support.

[0019] S2. Pull the first handle. At this time, the air chamber two will inflate into the air chamber one, squeeze the positioning post to descend, and engage it into the positioning port to position the inclination angle of the support rod.

[0020] S3. Start the dual-axis motor to drive the spiral drill rod and the winding wheel to rotate together. At this time, the spiral drill rod will descend and rotate at the same time, so as to achieve the drilling effect.

[0021] S4. After drilling, withdraw the spiral drill rod from the drill hole, release the first handle to reset the support rod, and at the same time pull the second handle to rise, driving the dual-axis motor and the spiral drill rod to rise back to the original position.

[0022] The beneficial effects of the hydrogeological and mining geological mine drilling device and its drilling method of the present invention are as follows:

[0023] The dual-axis motor controls the rotation of the spiral drill rod, and then can control the U-shaped fixing frame to descend along the interior of the contraction cylinder, so as to achieve the purpose of drilling. By rotating the support rod to an inclined state for support, at this time, air can be filled into the air chamber one through the first air exchange hole, driving the positioning post to engage into the positioning port, and the inclined support rod can be positioned to ensure that it cannot rotate after support and ensure the stability of the support.

[0024] Under normal conditions, the torsion spring will make the support rod fit against the outer wall of the contraction cylinder. When the bottom end of the support rod touches the ground and is subjected to a downward squeezing force, it will tilt and open to provide support. At this time, the sliding sleeve will slide along the outer wall of the support rod, and the connecting rod will move together to pull the support rod, ensuring that the support rod is more stable.

[0025] By holding two handles one and pulling them in opposite directions, the air chamber two can be inflated into the air chamber one, which can drive the positioning post to insert into the positioning port for positioning. By holding it by hand, while ensuring the stability of the device, the positioning of the support rod can be controlled.

[0026] When the biaxial motor is started to drive the spiral drill rod to rotate, the winding wheel will rotate together to wind the traction rope. At this time, the U-shaped fixing frame will descend along the inside of the contraction cylinder and be clamped into the wedge-shaped bayonet through the wedge-shaped piston block, preventing the U-shaped fixing frame from rising along the inside of the contraction cylinder, facilitating drilling while descending. When the drilling is completed, the handle two can be pulled upward. At this time, the air chamber four will extract the gas inside the air chamber three, causing the wedge-shaped piston block to contract and disengage from the wedge-shaped bayonet. At this time, the U-shaped fixing frame can be pulled upward to extract the spiral drill rod from the drilling hole. Brief Description of the Drawings

[0036] In the following, the present invention will be described in detail with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] According to one aspect of the present invention, as Figures 1-7 shown, a hydraulic ring geological mine drilling device is provided, including a shrinkage cylinder 1. The inner side of the shrinkage cylinder 1 is slidably connected with a U-shaped fixing frame 2. The upper surface of the inner side of the U-shaped fixing frame 2 is fixedly connected with a biaxial motor 3. The bottom end of the output shaft of the biaxial motor 3 is fixedly connected with an auger drill rod 4. The bottom end of the auger drill rod 4 extends below the shrinkage cylinder 1. The outer side wall of the shrinkage cylinder 1 is fixedly connected with a plurality of support mechanisms 5. The support mechanism 5 includes a connector 501. The lower surface of the connector 501 is provided with a rotation cavity 502. The inside of the rotation cavity 502 is rotationally connected with a rotation wheel 503 through a rotating shaft. The bottom of the rotation wheel 503 is fixedly connected with a support rod 504. The outer side wall of the rotation wheel 503 is provided with a positioning port 505. The inside of the connector 501 above the rotation cavity 502 is provided with an air chamber I 506. The upper surface of the inside of the air chamber I 506 is provided with a through-type air exchange hole I 507. The inside of the air chamber I 506 is slidably connected with a piston plate I 508. The inside of the piston plate I 508 is slidably connected with a positioning column 509. The bottom end of the positioning column 509 penetrates to the inside of the rotation cavity 502 and contacts the outer side wall of the rotation wheel 503. The opposite sides of the connector 501 and the shrinkage cylinder 1 are fixedly connected;

[0038] When the device is in use, the rotation of the spiral drill rod 4 is controlled by starting the biaxial motor 3. Then, the U-shaped fixing frame 2 can be controlled to descend along the inside of the contraction cylinder 1, and then the purpose of drilling can be achieved. When drilling, the support rod 504 can be rotated to an inclined state for support. At this time, air can be inflated into the first air cavity 506 through the first air exchange hole 507, driving the positioning column 509 to engage with the positioning port 505, so as to position the inclined support rod 504 and ensure that it cannot rotate after support, ensuring the stability of the support.

[0039] In this embodiment, a sliding sleeve 510 is slidably connected to the outer side wall of the support rod 504. Symmetrically fixed to the outer side wall of the sliding sleeve 510 are fixed columns 511. A rotating sleeve 512 is sleeved on the outer side wall of the fixed column 511. A connecting rod 513 is fixedly connected to the bottom of the rotating sleeve 512. The outer side wall of the connecting rod 513 is rotatably connected to a rotating column 514 through a rotating shaft. One end of the rotating column 514 away from the connecting rod 513 is fixedly connected to a fixed block 515. The fixed block 515 is fixedly connected to the opposite side of the contraction cylinder 1. A torsion spring 516 is sleeved on the outer side wall of the rotating column 514. The two ends of the torsion spring 516 are respectively fixedly connected to the opposite sides of the fixed block 515 and the connecting rod 513.

[0040] Under normal conditions, the torsion spring 516 will make the support rod 504 fit against the outer side wall of the contraction cylinder 1. When the bottom end of the support rod 504 touches the ground and is subjected to a downward pressing force, it will tilt and open to carry out support. At this time, the sliding sleeve 510 will slide along the outer side wall of the support rod 504, and the connecting rod 513 will move together, pulling the support rod 504 to ensure that the support rod 504 is more firm.

[0041] In this embodiment, a hand-held positioning mechanism 6 is fixedly connected to the front and rear surfaces of the contraction cylinder 1 and above the two connecting heads 501 that are opposite to each other front and back. The hand-held positioning mechanism 6 includes a second air cavity 601. A piston plate 602 is slidably connected to the inside of the second air cavity 601. A first spring 603 is fixedly connected between the piston plate 602 and the second air cavity 601. A through hole 604 is opened on the left side of the second air cavity 601. Two through-type air exchange holes 605 are opened on the front surface of the second air cavity 601. A handle 606 is arranged in front of the second air cavity 601. One side of the handle 606 close to the second air cavity 601 penetrates to the inside of the second air cavity 601 and is fixedly connected to the side of the piston plate 602 close to the first spring 603. The second air cavity 601 is fixedly connected to the opposite side of the contraction cylinder 1. Two sealing rings 607 are fixedly connected to the inner side wall of the second air cavity 601 on the outer side wall of the handle 606. The multiple air exchange holes 605 and the multiple air exchange holes 507 are respectively fixedly connected by an air exchange pipe 608.

[0042] After the support rod 504 is tilted and supported by downward extrusion, hold the two handles 606 by hand and pull them in opposite directions, so that the second air chamber 601 inflates into the first air chamber 506, which can drive the positioning column 509 to insert into the positioning port 505 for positioning. By hand support, while ensuring the stability of the device, the support rod 504 can be controlled for positioning. After the drilling is completed, release the handle 606. The piston plate 602 in the second air chamber 601 is reset under the pull of the first spring 603, and the gas filled into the first air chamber 506 is withdrawn, driving the positioning column 509 to reset, so that under the action of the torsion spring 516, the support rod 504 is reset.

[0043] In this embodiment, a plurality of wedge-shaped bayonets 7 are provided on both inner sides of the contraction cylinder 1. Symmetrically arranged below the inside of the U-shaped fixing frame 2 are third air chambers 8. Slidably connected inside the third air chambers 8 are wedge-shaped piston blocks 9. A second spring 10 is fixedly connected between the wedge-shaped piston blocks 9 and the third air chambers 8. The opposite sides of the two wedge-shaped piston blocks 9 are respectively engaged inside the two wedge-shaped bayonets 7 located above the inside of the contraction cylinder 1. An air groove 11 is provided on the upper inner surface of the third air chamber 8. Integrally formed at the top of the air groove 11 is a fourth air chamber 12. Slidably connected inside the fourth air chamber 12 is a piston block 13. Above the U-shaped fixing frame 2 is provided a second handle 14. The bottom of the second handle 14 respectively extends into the two fourth air chambers 12 and is fixedly connected to the upper surfaces of the two piston blocks 13. At the top of the dual-axis motor 3, a winding wheel 15 is fixedly connected above the U-shaped fixing frame 2. Fixedly connected to the outer side wall of the winding wheel 15 are two traction ropes 16. The bottom ends of the traction ropes 16 penetrate into the inside of the contraction cylinder 1 and are fixedly connected to the lower inner surface of the contraction cylinder 1.

[0044] When the dual-axis motor 3 is started to drive the screw drill rod 4 to rotate, the winding wheel 15 will rotate together to wind the traction rope 16. At this time, the U-shaped fixing frame 2 will descend along the inside of the contraction cylinder 1, and the wedge-shaped piston block 9 is engaged into the wedge-shaped bayonet 7 to prevent the U-shaped fixing frame 2 from rising along the inside of the contraction cylinder 1, which is convenient for drilling while descending. When the drilling is completed, the second handle 14 can be pulled upward. At this time, the fourth air chamber 12 will extract the gas inside the third air chamber 8, causing the wedge-shaped piston block 9 to contract and disengage from the wedge-shaped bayonet 7. At this time, the U-shaped fixing frame 2 can be pulled upward to extract the screw drill rod 4 from the drilling.

[0045] According to another aspect of the present invention, a method for drilling in a hydraulic ring geological mine is provided, including the following steps:

[0046] S1. Move the device to the drilling position so that the support rod 504 contacts the ground, and press down the device so that the support rod 504 is tilted and supported.

[0047] S2. Pull the first handle 606. At this time, the second air chamber 601 will be inflated into the first air chamber 506, squeezing the positioning post 509 to descend and engage into the positioning port 505 to position the inclination angle of the support rod 504.

[0048] S3. Start the dual-axis motor 3 to drive the auger 4 and the winding wheel 15 to rotate together. At this time, the auger 4 will rotate while descending to achieve the drilling effect.

[0049] S4. After drilling, withdraw the auger 4 from the drill hole, release the first handle 606 to reset the support rod 504. At the same time, pull the second handle 14 upward to drive the dual-axis motor 3 and the auger 4 to rise back to the original position.

[0050] All electrical components mentioned in this text are electrical components existing in reality.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also belong to the protection scope of the present invention.
