Description

Technical Field

[0001] This disclosure relates to the field of abrasive jet technology, and more particularly to a directional delivery system based on axial slits in abrasive jet. Background Technology

[0002] During underground mining, coal mines inevitably encounter the influence of hard roofs over coal seams. The hard roof over the coal seam makes it difficult for the roof of the mining face to collapse, causing large-scale roof overhangs and rock bursts behind and at the end of the working face, which affects the safe production of coal mines. Therefore, the treatment of roof strata is of utmost importance during coal mining.

[0003] Methods for treating roof strata include water injection weakening, hydraulic fracturing, explosive blasting, and abrasive jet axial directional fracturing. However, abrasive jet axial directional fracturing presents challenges. For larger drilling rigs, it is difficult to implement within the limited space of the longwall face and face end. For smaller drilling rigs, it is impossible to guarantee the directional effect of the cutting device during the pushing process. Consequently, abrasive jet axial directional fracturing fails to achieve the desired results. Summary of the Invention

[0027] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] like Figure 1 and Figure 2 As shown in the figure, this disclosure proposes a directional pushing system based on axial slit cutting of abrasive jet, including: a column 1, a frame 2, a first clamping device 3, a second clamping device 4, and a first driving member 5. The frame 2 is mounted on the column 1, the first clamping device 3 is mounted on the frame 2, and the first clamping device 3 is provided with a first clamping hole 6. The second clamping device 4 is slidably mounted on the frame 2, and the second clamping device 4 is provided with a second clamping hole 7. The central axis of the second clamping hole 7 coincides with the central axis of the first clamping hole 6, and the central axis of the second clamping hole 7 is parallel to the sliding direction of the second clamping device 4. The first driving member 5 is disposed between the second clamping device 4 and the frame 2, and the first driving member 5 drives the second clamping device 4 to move closer to or away from the first clamping device 3.

[0029] Understandably, when drilling the top plate, the drill rod 55 with the drill bit is first passed through the second clamping hole 7 and the first clamping hole 6 in sequence. Then, the second clamping device 4 is controlled to clamp the drill rod 55 with the drill bit, and at the same time, the first driving member 5 is controlled to move the second clamping device 4 closer to the first clamping device 3. Then, the first clamping device 3 is controlled to clamp the drill rod 55 with the drill bit, and at the same time, the second clamping device 4 is controlled to release the drill rod 55 with the drill bit. Then, the first driving member 5 is controlled to move the second clamping device 4 away from the first clamping device 3.

[0030] Then, add a drill rod 55, pass the added drill rod 55 through the second clamping hole 7 and connect it to the drill rod 55 with the drill bit. Then, control the second clamping device 4 to clamp the added drill rod 55, and at the same time control the first clamping device 3 to release the drill rod 55 with the drill bit. Then, control the first driving member 5 to move the second clamping device 4 closer to the first clamping device 3. Then, control the first clamping device 3 to clamp the added drill rod 55, and at the same time control the second clamping device 4 to release the added drill rod 55. Then, control the first driving member 5 to move the second clamping device 4 away from the first clamping device 3.

[0031] The process of adding drill rod 55 is repeated until the drill bit is against the top plate. Then, the second clamping device 4 is controlled to clamp the last added drill rod 55, while the first clamping device 3 is controlled to release it. The drill bit is then started, and the first drive member 5 is simultaneously controlled to bring the second clamping device 4 closer to the first clamping device 3. Thus, using the second clamping device 4 as a pushing component and the first clamping device 3 as a guiding component, drilling into the top plate is achieved.

[0032] When performing axial directional cutting and fracturing with abrasive jet, the cutting and fracturing device 56 is installed in the borehole by performing the same operation as the drilling described above.

[0033] Through the cooperation of the first clamping device 3, the second clamping device 4, and the first driving component 5, drilling, in-hole slit cutting, and fracturing of the roof are achieved. The overall structure is not only simple and small in size, making it easy to carry out construction operations in limited spaces such as fully mechanized mining faces and face ends, but it also enables directional and stable pushing. This allows the abrasive jet axial directional slit cutting and fracturing technology to be implemented efficiently and with high quality, ensuring safe production in coal mines.

[0034] It should be noted that the abrasive jet axial directional cutting fracturing technology refers to drilling a hole in a hard top plate. After drilling, an abrasive jet device is used to directionally cut the hole wall, creating a crack of a certain depth. Then, high-pressure water is injected into the crack through a fracturing device to cause the crack to expand along a predetermined direction, thereby achieving the purpose of depressurizing the top plate.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the frame 2 is rotatably mounted on the column 1, and the directional pushing system further includes a second driving member 8, which is disposed between the frame 2 and the column 1, and drives the frame 2 to rotate on the column 1.

[0036] Understandably, by controlling the second drive component 8, the frame 2 is rotated on the column 1, and the first clamping device 3 and the second clamping device 4 on the frame 2 rotate synchronously, thereby adjusting the pushing direction. This allows the directional pushing system to adapt to different roof conditions during drilling, in-hole cutting, and fracturing, making it more versatile. At the same time, by controlling the second drive component 8, the frame 2 can be rotated to the required angle, for example, making the frame 2 parallel to the length of the roadway. This reduces the overall height of the directional pushing system, making it easier to move and operate underground.

[0037] like Figure 2 As shown, in some embodiments, the directional pushing system further includes an angle sensor (not shown) and a controller 9. The angle sensor is disposed between the frame 2 and the column 1, and the controller 9 is electrically connected to the angle sensor, the first drive unit 5 and the second drive unit 8 respectively.

[0038] Understandably, the angle sensor detects the angle between the frame 2 and the column 1 and converts the angle signal into an electrical signal, which is then sent to the controller 9. The controller 9 controls the second drive member 8 to rotate the frame 2 to the set angle based on the electrical signal. At the same time, the controller 9 controls the first drive member 5 to move the second clamping device 4.

[0039] Therefore, by setting up controller 9 and angle sensors, the overall automation level of the directional pushing system is improved, effectively increasing overall work efficiency and reducing overall work costs.

[0040] In some embodiments, a limit device is provided between the frame 2 and the second clamping device 4. The limit device includes a limit switch and a limit pin. The limit pin is fixedly mounted on the second clamping device 4, and the limit switch is mounted on the frame 2 and electrically connected to the controller 9. It is understood that when the limit switch detects the limit pin, it sends an electrical signal to the controller 9. The controller 9 then controls the first driving member 5 to stop operating based on this electrical signal, thereby ensuring the safe movement of the second clamping device 4.

[0041] like Figure 3As shown, in some embodiments, a stroke detection device is provided between the frame 2 and the second clamping device 4. The stroke detection device includes an encoder 10, a detection gear 11, and a rack 12. The encoder 10 is fixedly mounted on the second clamping device 4 and is electrically connected to the controller 9. The detection gear 11 is fixedly mounted on the detection shaft of the encoder 10, and the rack 12 is fixedly mounted on the frame 2 along the sliding direction of the second clamping device 4. The detection gear 11 meshes with the rack 12. It can be understood that when the second clamping device 4 moves, it drives the detection gear 11 to rotate relative to the rack 12. The detection gear 11 drives the detection shaft of the encoder 10 to rotate. The encoder 10 converts the number of rotations of the detection shaft into an electrical signal and sends it to the controller 9. The controller 9 calculates the moving distance of the second clamping device 4 on the frame 2 based on the electrical signal and the circumference of the detection gear 11, and controls the action of the first driving member 5 according to the moving distance of the second clamping device 4 on the frame 2, thereby further improving the overall automation level of the directional pushing system.

[0042] like Figure 1 As shown, in some embodiments, the frame 2 includes a first part 13, a second part 14 and a third drive member 15. The first part 13 is rotatably mounted on the column 1, the second clamping device 4 is slidably mounted on the first part 13, and the third drive member 15 is disposed between the first part 13 and the second part 14. The third drive member 15 drives the second part 14 to move closer to or away from the first part 13.

[0043] It is understandable that by controlling the third drive component 15, the second part 14 is moved relative to the first part 13, thereby adjusting the length of the frame 2. This not only enables the directional pushing system to adapt to drill rods 55 of different lengths, making it more versatile, but also reduces the volume of the directional pushing system by bringing the second part 14 closer to the first part 13 and shortening the length of the frame 2. This makes the system easier to operate in limited spaces such as the fully mechanized mining face and the end of the face.

[0044] In some embodiments, both the first part 13 and the second part 14 include multiple longitudinal beams and multiple transverse beams. The longitudinal beams are arranged in parallel, and the transverse beams are connected to the longitudinal beams respectively. The transverse beams are evenly distributed along the length of the longitudinal beams. It is understood that this structure can improve the strength of the frame 2 and ensure that the directional pushing device as a whole can operate stably.

[0045] In some embodiments, a guide rail is provided on the longitudinal beam of the first part 13, and a rail groove is provided on the second clamping device 4, with the guide rail and the rail groove being slidably connected. It can be understood that the second clamping device 4 is slidably positioned on the first part 13 by the arrangement of the guide rail and the rail groove.

[0046] like Figure 1As shown, in some embodiments, the first clamping device 3 includes a first clamp 16, which is disposed on the second part 14, and the clamping end of the first clamp 16 forms a first clamping hole 6. The second clamping device 4 includes a second clamp 17, which is slidably disposed on the first part 13, and the clamping end of the second clamp 17 forms a second clamping hole 7.

[0047] Understandably, through the clamping and releasing of the first clamper 16 and the second clamper 17, and in conjunction with the action of the first driving component 5, drilling, in-hole slit cutting, and fracturing of the roof plate are achieved, and directional and stable pushing can be realized. This enables the efficient and high-quality implementation of the abrasive jet axial directional slit cutting fracturing technology, ensuring safe production in coal mines.

[0048] like Figure 4 As shown, in some embodiments, the first clamp 16 includes a first clamping seat 18, a second clamping seat 19, a first piston rod 20, a second piston rod 21, a first gripper 22, and a second gripper 23. The first clamping seat 18 and the second clamping seat 19 are fixedly connected by a long bolt 24. The first clamping seat 18 is provided with a first piston hole at one end near the second clamping seat 19, and the second clamping seat 19 is provided with a second piston hole at one end near the first clamping seat 18. One end of the first piston rod 20 is slidably inserted into the first piston hole. The first gripper 22 is fixedly disposed at the other end of the first piston rod 20. One end of the second piston rod 21 is slidably inserted into the second piston hole. The second gripper 23 is fixedly disposed at the other end of the second piston rod 21, and a first clamping hole 6 is formed between the first gripper 22 and the second gripper 23.

[0049] Understandably, the pressure medium applies a thrust to the first piston rod 20 and the second piston rod 21 within the first piston hole and the second piston hole, causing the first gripper 22 and the second gripper 23 to move synchronously in opposite directions, thereby achieving the clamping and release of the drill rod 55.

[0050] like Figure 4 As shown, in some embodiments, the first clamp 16 further includes a guide ring 25, which is fixedly mounted on the first clamping seat 18. The central axis of the guide ring 25 coincides with the central axis of the first clamping hole 6, and the diameter of the guide ring 25 is smaller than the maximum diameter of the first clamping hole 6, while the diameter of the guide ring 25 is larger than the diameter of the drill rod 55. Multiple balls 26 are rotatably disposed on the inner wall of the guide ring 25. It is understood that when the first clamp 22 and the second clamp 23 clamp the drill rod 55, the inner wall of the guide ring 25 does not contact the drill rod 55. When the first clamp 22 and the second clamp 23 release the drill rod 55, the balls 26 on the inner wall of the guide ring 25 contact the drill rod 55. Therefore, while ensuring that the drill rod 55 can be stably clamped, the pushing of the drill rod 55 is smoother, effectively reducing the wear on the drill rod 55 and extending its service life.

[0051] In some embodiments, the first clamp 16 and the second clamp 17 have the same structure.

[0052] like Figure 2 and Figure 5 As shown, in some embodiments, the directional push system further includes a first reversing valve 27, a second reversing valve 28, a third reversing valve 29, a fourth reversing valve 30, and a fifth reversing valve 31;

[0053] Wherein, the first end of the first reversing valve 27 is connected to the first end of the first driving member 5, the second end of the first reversing valve 27 is connected to the second end of the first driving member 5, the third end of the first reversing valve 27 is connected to the external power source 32, and the fourth end of the first reversing valve 27 is connected to the external recovery source 33. Wherein, the first end of the first reversing valve 27 is connected to the third end of the first reversing valve 27, and the second end of the first reversing valve 27 is connected to the fourth end of the first reversing valve 27, or the first end of the first reversing valve 27 is connected to the fourth end of the first reversing valve 27, and the second end of the first reversing valve 27 is connected to the third end of the first reversing valve 27.

[0054] The first end of the second reversing valve 28 is connected to the first end of the second driving member 8, the second end of the second reversing valve 28 is connected to the second end of the second driving member 8, the third end of the second reversing valve 28 is connected to the power source 32, and the fourth end of the second reversing valve 28 is connected to the recovery source 33. In this case, the first end of the second reversing valve 28 is connected to the third end of the second reversing valve 28, and the second end of the second reversing valve 28 is connected to the fourth end of the second reversing valve 28, or the first end of the second reversing valve 28 is connected to the fourth end of the second reversing valve 28, and the second end of the second reversing valve 28 is connected to the third end of the second reversing valve 28.

[0055] The first end of the third directional valve 29 is connected to the first end of the third drive member 15, the second end of the third directional valve 29 is connected to the second end of the third drive member 15, the third end of the third directional valve 29 is connected to the power source 32, and the fourth end of the third directional valve 29 is connected to the recovery source 33. In this case, the first end of the third directional valve 29 is connected to the third end of the third directional valve 29, and the second end of the third directional valve 29 is connected to the fourth end of the third directional valve 29, or the first end of the third directional valve 29 is connected to the fourth end of the third directional valve 29, and the second end of the third directional valve 29 is connected to the third end of the third directional valve 29.

[0056] The first end of the fourth reversing valve 30 is connected to the first end of the first clamp 16, the second end of the fourth reversing valve 30 is connected to the second end of the first clamp 16, the third end of the fourth reversing valve 30 is connected to the power source 32, and the fourth end of the fourth reversing valve 30 is connected to the recovery source 33. In this case, the first end of the fourth reversing valve 30 is connected to the third end of the fourth reversing valve 30, and the second end of the fourth reversing valve 30 is connected to the fourth end of the fourth reversing valve 30, or the first end of the fourth reversing valve 30 is connected to the fourth end of the fourth reversing valve 30, and the second end of the fourth reversing valve 30 is connected to the third end of the fourth reversing valve 30.

[0057] The first end of the fifth directional valve 31 is connected to the first end of the second clamp 17, the second end of the fifth directional valve 31 is connected to the second end of the second clamp 17, the third end of the fifth directional valve 31 is connected to the power source 32, and the fourth end of the fifth directional valve 31 is connected to the recovery source 33. In this case, the first end of the fifth directional valve 31 is connected to the third end of the fifth directional valve 31, and the second end of the fifth directional valve 31 is connected to the fourth end of the fifth directional valve 31, or the first end of the fifth directional valve 31 is connected to the fourth end of the fifth directional valve 31, and the second end of the fifth directional valve 31 is connected to the third end of the fifth directional valve 31.

[0058] Understandably, the power source 32 outputs a pressure medium, which, through the switching of the first reversing valve 27, facilitates the exchange of the pressure medium between the first driving member 5 and the power source 32 and the recovery source 33, thereby driving the first driving member 5 to move and realize the movement of the second clamping device 4 on the frame 2; through the switching of the second reversing valve 28, the pressure medium is exchanged between the second driving member 8 and the power source 32 and the recovery source 33, thereby driving the second driving member 8 to move and realize the rotation of the frame 2 on the column 1; through the switching of the third reversing valve 29, the pressure medium is exchanged between the third driving member 1 and the power source 32 and the recovery source 33. The exchange between the first clamp 16 and the power source 32 and the recovery source 33 drives the third drive component 15 to adjust the length of the frame 2. The exchange between the first clamp 16 and the power source 32 and the recovery source 33 is achieved through the switching of the fourth reversing valve 30, thereby driving the first clamp 16 to clamp and release the drill pipe 55. The exchange between the second clamp 17 and the power source 32 and the recovery source 33 is achieved through the switching of the fifth reversing valve 31, thereby driving the second clamp 17 to clamp and release the drill pipe 55.

[0059] In some embodiments, the first drive member 5, the second drive member 8 and the third drive member 15 may be hydraulic telescopic cylinders, the first clamp 16 and the second clamp 17 may be hydraulic clamps, the hydraulic station serves as the power source 32 and the recovery source 33, and the pressure medium is hydraulic oil.

[0060] In some embodiments, the first drive member 5, the second drive member 8 and the third drive member 15 may be telescopic cylinders, the first clamp 16 and the second clamp 17 may be pneumatic clamps, the air compressor serves as the power source 32, the recovery source 33 may be an external open space, and the pressure medium is compressed air.

[0061] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the column 1 includes a plurality of columns 34, which are slidably connected in sequence, and the first part 13 is rotatably disposed on the outermost column 34.

[0062] The directional push system also includes: a sixth reversing valve 35, the first end of which is connected to the first end of the column 1, the second end of which is connected to the second end of the column 1, the third end of which is connected to the power source 32, and the fourth end of which is connected to the recovery source 33. Specifically, the first end of the sixth reversing valve 35 is connected to the third end of the sixth reversing valve 35, and the second end of the sixth reversing valve 35 is connected to the fourth end of the sixth reversing valve 35, or the first end of the sixth reversing valve 35 is connected to the fourth end of the sixth reversing valve 35, and the second end of the sixth reversing valve 35 is connected to the third end of the sixth reversing valve 35.

[0063] Understandably, the power source 32 outputs a pressure medium, and through the switching of the sixth directional valve 35, the pressure medium is exchanged between the column 1 and the power source 32 and the recovery source 33, thereby causing multiple columns 34 to move to achieve the extension and retraction of the column 1. When the column 1 extends, it presses against the top plate to ensure the stability of the drilling operation. When the column 1 retracts, it reduces the overall height of the directional pushing system, thereby facilitating the movement and construction of the directional pushing system downhole and effectively improving the overall flexibility.

[0064] like Figure 1 As shown, in some embodiments, a backing plate 36 is fixedly installed on the innermost column, and a plurality of protrusions 37 are provided on the backing plate 36. It can be understood that by setting the backing plate 36 and the protrusions 37, the column 1 can be stably abutted against the top plate, thereby ensuring the stability of the directional pushing system.

[0065] In some embodiments, the column 1 can be a multi-stage hydraulic telescopic cylinder, the hydraulic station serves as the power source 32 and the recovery source 33, and the pressure medium is hydraulic oil.

[0066] In some embodiments, the column 1 can be a multi-stage telescopic cylinder, the air compressor serves as the power source 32, the recovery source 33 is an external open space, and the pressure medium is compressed air.

[0067] like Figure 1 and Figure 2As shown, in some embodiments, the directional pushing system further includes a clamp 38, a support rod 39, and a connecting cylinder 40. The clamp 38 is fixedly sleeved on the outermost column 34, the support rod 39 is fixedly mounted on the clamp 38, and the connecting cylinder 40 is fixedly connected to the frame and rotatably mounted on the support rod 39.

[0068] It is understandable that the frame 2 is rotated on the column 1 by means of the clamp 38, support rod 39 and connecting cylinder 40, which is highly stable and easy to disassemble and assemble.

[0069] In some embodiments, the clamp 38 is a cylindrical structure with an opening on one side. The clamp 38 forms two free ends at its opening, and ear plates are fixedly provided on both free ends. The ear plates of the two free ends are connected by bolts, so that the clamp 38 is fixed on the column 1 after the bolts are tightened, and the position of the clamp 38 on the column 1 can be adjusted and the clamp 38 can be removed from the column 1 after the bolts are loosened.

[0070] In some embodiments, an anti-slip pad may be provided on the inner wall of the clamp 38. It is understood that after the clamp 38 is fixedly fitted onto the column 1, the anti-slip pad is located between the clamp 38 and the column 1, thereby effectively increasing the friction between the clamp 38 and the column 1, making the clamp 38 more stable and secure on the column 1.

[0071] In some embodiments, the anti-slip pad may be made of rubber or silicone material, and multiple prismatic protrusions may be provided on the anti-slip pad.

[0072] In some embodiments, the angle sensor is fixedly mounted on the connecting cylinder 40, and the detection shaft of the angle sensor is fixedly connected to the support rod 39.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments, a limiting member 41 is provided on the outermost column. The limiting member 41 is used to limit the clamp 38 so as to ensure that the clamp 38 can be stably fitted on the appropriate position on the outermost column.

[0074] In some embodiments, the limiting member 41 may be a limiting block or a limiting rod.

[0075] In some embodiments, a lifting ring is fixedly installed on the innermost column, and the lifting ring is connected to the tunnel floor by a steel wire rope to further improve the overall stability of the directional pushing system.

[0076] like Figure 2As shown, in some embodiments, the directional pushing system also includes a tracked chassis 42, an operating platform 43, and multiple telescopic outriggers 44. The column 1 is mounted on the chassis of the tracked chassis 42, the operating platform 43 is mounted on the chassis, the first reversing valve 27, the second reversing valve 28, the third reversing valve 29, the fourth reversing valve 30, the fifth reversing valve 31, and the sixth reversing valve 35 are mounted on the operating platform 43, and the telescopic outriggers 44 are mounted on the chassis, with multiple telescopic outriggers 44 distributed around the tracked chassis 42.

[0077] Understandably, the tracked chassis 42 enables the directional pushing system to move stably within a limited space; the control panel 43 facilitates centralized control of components such as the column 1, the first drive component 5, the second drive component 8, the first clamping device 3, and the second clamping device 4 by operators, effectively improving the overall construction efficiency of the directional pushing system and reducing labor costs; and the telescopic outriggers 44 ensure stable construction even when the directional pushing system is on an inclined surface, effectively improving the construction stability and safety of the directional pushing system.

[0078] In some embodiments, the control unit and controller 9 of the tracked chassis 42 can both be mounted on the control panel 43.

[0079] like Figure 2 and Figure 5 As shown, in some embodiments, the directional pushing system further includes a seventh reversing valve 45, which is disposed on the operating table 43. The first end of the seventh reversing valve 45 is connected to the first end of the telescopic outrigger 44, the second end of the seventh reversing valve 45 is connected to the second end of the telescopic outrigger 44, the third end of the seventh reversing valve 45 is connected to the power source 32, and the fourth end of the seventh reversing valve 45 is connected to the recovery source 33. In this case, the first end of the seventh reversing valve 45 is connected to the third end of the seventh reversing valve 45, and the second end of the seventh reversing valve 45 is connected to the fourth end of the seventh reversing valve 45, or the first end of the seventh reversing valve 45 is connected to the fourth end of the seventh reversing valve 45, and the second end of the seventh reversing valve 45 is connected to the third end of the seventh reversing valve 45.

[0080] It is understandable that the power source 32 outputs a pressure medium, and through the switching of the seventh reversing valve 45, the pressure medium is exchanged between the telescopic outrigger 44 and the power source 32 and the recovery source 33, thereby driving the telescopic outrigger 44 to extend and retract, so as to realize the movement and reset of the tracked chassis 42.

[0081] In some embodiments, the telescopic outrigger 44 can be a hydraulic outrigger, with the hydraulic station serving as the power source 32 and the recovery source 33, and the pressure medium being hydraulic oil.

[0082] In some embodiments, the telescopic outrigger 44 can be a pneumatic outrigger, the air compressor serves as the power source 32, the recovery source 33 can be an external open space, and the pressure medium is compressed air.

The rotating device 46 includes a first rotating seat 47, a second rotating seat 48, a large gear 49, a small gear 50, and a fourth driving member 51. The column 1 is fixedly mounted on the first rotating seat 47. The first rotating seat 47 is rotatably mounted on the second rotating seat 48 via a slewing bearing. The second rotating seat 48 is fixedly mounted on the chassis. The fourth driving member 51 is fixedly mounted on the first rotating seat 47 and is electrically connected to the controller 9. The small gear 50 is fixedly mounted on the output shaft of the fourth driving member 51. The large gear 49 is fixedly mounted on the second rotating seat 48, and the small gear 50 meshes with the large gear 49. Understandably, the controller 9 controls the fourth drive component 51 to rotate the small gear 50 relative to the large gear 49, thereby driving the first rotating seat 47 to rotate relative to the second rotating seat 48, thus realizing the rotation of the column 1. In turn, in conjunction with the rotation of the frame 2, the directional pushing system can adapt to different top plate conditions when drilling, cutting slits in holes, and fracturing, making it more versatile.

[0084] In some embodiments, a level detection device is provided on the frame 2. The level detection device includes a tilt sensor, which is fixedly mounted on the frame 2 and electrically connected to the controller 9. It is understood that the tilt sensor detects the tilt angle of the frame 2 and converts the tilt angle into an electrical signal, which is then sent to the controller 9. The controller 9 controls the fourth drive unit 51 to operate based on this electrical signal, and simultaneously controls the second drive unit 8 to operate based on the electrical signal sent by the tilt sensor, thereby adjusting the angle of the frame 2.

[0085] like Figure 2 and Figure 5 As shown, in some embodiments, the directional pushing system further includes an eighth reversing valve 52, which is disposed on the operating table 43.

In this case, the first end of the eighth reversing valve 52 is connected to the third end of the eighth reversing valve 52, and the second end of the eighth reversing valve 52 is connected to the fourth end of the eighth reversing valve 52, or the first end of the eighth reversing valve 52 is connected to the fourth end of the eighth reversing valve 52, and the second end of the eighth reversing valve 52 is connected to the third end of the eighth reversing valve 52.

[0086] It is understandable that the power source 32 outputs a pressure medium, and through the switching of the eighth directional valve 52, the pressure medium is exchanged between the fourth drive member 51 and the power source 32 and the recovery source 33, thereby driving the fourth drive member 51 to move, so as to realize the rotation of the first rotating seat 47 on the second rotating seat 48.

[0087] In some embodiments, the fourth drive element 51 may be a hydraulic motor, the hydraulic station serves as the power source 32 and the recovery source 33, and the pressure medium is hydraulic oil.

It is understood that, through the control of the controller 9, the first reversing valve 27, the second reversing valve 28, the third reversing valve 29, the fourth reversing valve 30, the fifth reversing valve 31, the sixth reversing valve 35, the seventh reversing valve 45, and the eighth reversing valve 52 are switched to achieve the construction operation of the directional pushing system.

[0090] In some embodiments, the first and second ends of the first reversing valve 27, the second reversing valve 28, the third reversing valve 29, the fourth reversing valve 30, the fifth reversing valve 31, the sixth reversing valve 35, the seventh reversing valve 45, and the eighth reversing valve 52 are all equipped with electromagnetic switching valves, which are electrically connected to the controller 9. Thus, by controlling the electromagnetic switching valves through the controller 9, stable control of the first driving member 5, the second driving member 8, the third driving member 15, the fourth driving member 51, the first clamp 16, the second clamp 17, the column 1, and the telescopic outrigger 44 is achieved.

[0091] like Figure 2 As shown, in some embodiments, the control panel 43 is provided with an input main pipe 53 and an output main pipe 54. The fourth ends of the first reversing valve 27, the second reversing valve 28, the third reversing valve 29, the fourth reversing valve 30, the fifth reversing valve 31, the sixth reversing valve 35, the seventh reversing valve 45 and the eighth reversing valve 52 are all connected to the recovery source 33 through the output main pipe 54, and the third ends of the first reversing valve 27, the second reversing valve 28, the third reversing valve 29, the fourth reversing valve 30, the fifth reversing valve 31, the sixth reversing valve 35, the seventh reversing valve 45 and the eighth reversing valve 52 are all connected to the power source 32 through the input main pipe 53.

The multiple drill rods 55 are disposed in the first clamping hole 6 and the second clamping hole 7, and a cutting and fracturing device 56 is disposed on the drill rod 55 away from the second clamping hole 7.

[0093] Understandably, through the continuous pushing of the directional pushing system, the slotting and fracturing device 56 performs slotting and water injection into the borehole, thereby ensuring the efficient and high-quality implementation of the abrasive jet axial directional slotting and fracturing technology.

[0094] It should be noted that the slotting fracturing device 56 is used to spray abrasive water into the borehole to slot the borehole. At the same time, the slotting fracturing device 56 is also used to inject high-pressure water into the slot to expand the slot.

[0095] In some embodiments, adjacent drill pipes 55 can be fixedly connected by means of threaded fixing, snap-fit ​​fixing, or other methods.
