Description

A guide drill rod for a horizontal directional drilling rig Technical Field

[0001] This invention relates to the field of drilling rig guide drill rods, specifically a horizontal directional drilling rig guide drill rod. Background Technology

[0002] Drilling is a systematic project, involving multiple disciplines and trades working together using various equipment, tools, and materials. It is also a continuous operation with multiple procedures closely linked and multiple stages interlocking, making the entire construction process quite complex.

[0003] Drilling rigs utilize drill bits on drill rods to cut through soil layers. The rotation and forward movement of the drill rod propels the drill bit forward. The drill rod is first lowered to the wellhead. Rotating the drill rod drives the drill bit to cut the soil. Drilling gears drive the mandrel to rotate, which in turn transmits the rotational power to the mandrel and coupling inside the steel pipe, causing the entire drill rod to rotate. As the drill bit cuts the soil, the propulsive force of the drill rod and the energy of the drill bit cause it to advance continuously, gradually increasing the drilling depth. The forward movement of the drill rod is usually achieved through a combination of rotation and propulsion; the rotation of the drill rod simultaneously propels the drill bit forward.

[0004] The drill pipe drive system is too complex and has the problem of being inconvenient to disassemble and replace. The drill pipe body is easily damaged during use, which leads to the paralysis of the horizontal directional drilling rig's guide drill pipe drilling, thus reducing the operating efficiency of the horizontal directional drilling rig's guide drill pipe. Summary of the Invention

[0005] The purpose of this invention is to provide a guide drill rod for a horizontal directional drilling rig to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guide drill rod for a horizontal directional drilling rig, comprising: a concave frame; a motor is fixedly connected inside the positive end of the concave frame, the output shaft of the motor passes through the front end of the concave frame and is fixedly connected to an adjusting bracket, the motor can adjust the connection angle between the concave frame and the adjusting bracket, thereby changing the drilling angle, enabling smoother drilling during operation and improving the performance of the drilling rig; a positioning frame is movably connected to the top of the adjusting bracket, a mounting frame is fixedly connected to the upper left side of the positioning frame, a drive motor is fixedly connected to the center of the mounting frame, and a sleeve is fixedly connected to the output shaft of the drive motor, the inner cavity of the sleeve being magnetically connected. The drill rod has a movable groove on the upper right side of the positioning frame. The movable frame is slidably connected inside the movable groove. The rotational force of the drill rod is provided by the drive motor. Therefore, it changes the original drilling gear driving the mandrel to rotate. The mandrel then transmits the rotational power to the mandrel and coupling inside the steel pipe, so that the entire drill rod rotates. The rotational force transmission is more direct, and there is no leakage in the middle, which ensures the stable and continuous operation of the drill rod and improves drilling efficiency. In addition, the drill rod is connected to the drive motor through the intervention of the sleeve. The drill rod and the sleeve generate magnetic attraction, which not only ensures the connection is firm and the operation is stable, but also facilitates the replacement of worn drill rods. This makes the drilling rig more smooth and convenient to use, and further improves the utilization rate of the drilling rig.

[0007] As a further aspect of the present invention: a sealing ring is fixedly connected to the center of the movable frame, and the inner wall of the sealing ring is movably connected to the outer wall of the drill rod. By setting the sealing ring at the center of the movable frame, the drill rod is guided into the sealing ring, and the movable frame slides to the left along the moving groove set in the positioning frame, so that the drill rod is accurately guided into the sleeve. Thus, the drill rod rotates synchronously with the drive shaft of the drive motor. In addition, the movable frame slides to the right along the moving groove set in the positioning frame, and the drill rod is removed from the magnetic range of the sleeve. The worn drill rod can then be taken out from the sealing ring for replacement, making the drilling rig smoother and more convenient to use, and further improving the utilization rate of the drilling rig.

[0008] As a further embodiment of the present invention: a reduction motor and a connecting block are fixedly connected to the back of the adjusting bracket respectively. A drive bolt is rotatably connected to the center of the connecting block. The left side of the drive bolt is fixedly connected to the output shaft of the reduction motor. The connecting block is located on the right side of the rear end of the adjusting bracket, and the reduction motor is located on the left side of the rear end of the adjusting bracket. In addition, the center of the reduction motor and the center of the connecting block are symmetrically arranged. Therefore, the drive bolt moves horizontally, which plays a crucial role in the subsequent adjustment of the stability of the positioning frame movement.

[0009] As a further embodiment of the present invention: the outer wall of the drive bolt is threaded with a sliding frame, and the back of the adjusting bracket is provided with a sliding groove from the outside to the inside. The sliding frame is movably connected to the groove of the sliding groove at one end of the drive bolt. The sliding frame is disposed in the sliding groove, and a small part of the rear end of the sliding frame is exposed outside the adjusting bracket. The horizontal movement direction of the sliding frame in the groove is controlled by the drive bolt, and the direction of rotation of the drive bolt is controlled by the reduction motor.

[0010] As a further aspect of the present invention: a connecting frame is fixedly connected to one end of the sliding frame in the sliding groove. The top of the connecting frame is fixedly connected to the bottom of the positioning frame. The connecting frame moves around the upper groove of the adjusting bracket and acts as a series connection, enabling the sliding frame and the positioning frame to communicate. Therefore, the moving direction of the sliding frame directly controls the moving direction of the positioning frame, thereby adjusting the position of the positioning frame on the adjusting bracket. The drill rod moves smoothly with the adjustment of the positioning frame, achieving the function of changing positions. This allows for smoother drilling during operation and improves the effectiveness of the drilling machine.

[0011] As a further embodiment of the present invention: a fixed frame and a support frame are fixedly connected to the upper and lower ends of the concave frame, respectively. A drive frame is fixedly connected to the left side of both the fixed frame and the support frame. A traction frame is fixedly connected to the front of the drive frame. The fixed frame and the support frame are respectively located at the upper and lower ends of the left side of the concave frame, which can not only support the concave frame, but also ensure the stability of the concave frame during subsequent lifting and lowering, thereby improving the drilling stability and drilling guidance level of the drilling rig.

[0012] As a further embodiment of the present invention: the drive frame is threaded with an adjusting bolt at its center, a servo motor is fixedly connected to the top of the adjusting bolt, and a vertical support is fixedly connected to the outer wall of the servo motor. The drive frame is respectively set on the left side of the fixed frame and the support frame. The adjusting bolt can adjust the drive frame's movement on the vertical support. In addition, the direction of the adjusting bolt is controlled by the servo motor, so the user can control the direction of the drive frame's movement and control the drill rod to rise and fall, thereby changing the angle. This allows for smoother drilling during operation and improves the drilling machine's performance.

[0013] As a further embodiment of the present invention: the upper and lower ends of the vertical support are provided with a drive groove and a traction groove. The outer wall of the drive frame is movably connected to the groove of the drive groove. The traction frame is movably connected to the groove of the traction groove at one end of the drive frame. The traction frame is set on the front of the drive frame. The traction frame moves stably around the traction groove. Therefore, the drive frame moves synchronously and stably within the drive groove. Only by adjusting the bolt can the lifting and lowering of the drive frame be stably controlled.

[0014] As a further embodiment of the present invention: a support base is fixedly connected to the bottom of the vertical support, and tracked walking components are fixedly connected to both ends of the support base. This provides support for the drilling without affecting the drilling's position movement. The tracked walking component includes tracks, track wheels, track frames, and a drive motor. The track wheels are rotatably fitted onto the track frames and driven to rotate by the drive motor. The track wheels are sprockets that drive the tracks to rotate and move. The track frames serve as the base, which is fixedly connected to both ends of the support base. The tracks consist of track plates, track chains, and pins. Tracked walking devices are mature existing technologies and will not be described in detail. The tracked walking structure can adapt to complex downhole terrain and working environments, improving the applicable working conditions range of the drill pipe conveying device.

[0015] As a further embodiment of the present invention: both ends of the support base are fixedly connected to connecting frames, and a supporting hydraulic cylinder is fixedly connected inside the connecting frame. The output end of the supporting hydraulic cylinder is fixedly connected to a foot pad. The connecting frame, the supporting hydraulic cylinder and the foot pad are combined to form a telescopic support assembly. When the telescopic support is extended, the telescopic support assembly is supported on the ground, and the support base, the tracked walking assembly and other components are suspended in the air, providing a stable working environment for the guide drill rod of the horizontal directional drilling rig. When the telescopic support assembly is shortened, the walking device is supported on the bottom surface and can drive the frame assembly and other components to move.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Through the setting of concave frame, adjusting bracket and motor, the motor can adjust the connection angle between concave frame and adjusting bracket. The lower right side of the adjusting bracket can be adjusted to be tightly connected to the right side of the support base, so as to change the drilling angle, so that drilling can be carried out more smoothly during operation and the use effect of drilling rig is improved.

[0018] 2. By adjusting the settings of the bracket, positioning frame, mounting frame, moving slot, drive motor, drill pipe, sleeve, and moving frame, the rotational force of the drill pipe is provided by the drive motor. This changes the original method where the drilling gear drives the mandrel to rotate, and the mandrel then transmits the rotational power to the mandrel and coupling inside the steel pipe. This allows the entire drill pipe to rotate, making the force transmission more direct and eliminating any leakage. This ensures the stable and continuous operation of the drill pipe and improves drilling efficiency. In addition, the connection between the drill pipe and the drive motor is achieved through the sleeve. The drill pipe and the sleeve generate magnetic attraction, which ensures both a strong connection and operational stability, and facilitates the replacement of worn drill pipe. This makes the drilling rig easier and more convenient to use, further improving the utilization rate of the drilling rig.

[0019] 3. Through the arrangement of positioning frame, slide groove, connecting block, sliding frame, geared motor, drive bolt, connecting frame and adjusting bracket, the connecting frame moves around the upper groove of the adjusting bracket, and the connecting frame plays a connecting role, so that the sliding frame and positioning frame are connected. Therefore, the moving direction of the sliding frame directly controls the moving direction of the positioning frame, thereby adjusting the position of the positioning frame on the adjusting bracket. The drill rod moves smoothly with the adjustment of the positioning frame, achieving the function of changing the position, so that drilling can be performed more smoothly during operation, and improving the use effect of the drilling machine.

[0020] 4. The system consists of a vertical support, servo motor, drive frame, drive slot, traction frame, traction slot, adjusting bolt, fixed frame, support frame, and concave frame. The drive frame is located on the left side of the fixed frame and support frame. The adjusting bolt can adjust the drive frame's height on the vertical support. Furthermore, the direction of the adjusting bolt is controlled by the servo motor, allowing the user to control the direction of the drive frame's movement and the drill rod's height adjustment, thus changing the angle. This makes drilling smoother during operation and improves the drilling machine's performance.

[0021] 5. By setting up a support base, tracked walking assembly, connecting frame, foot pads and support hydraulic cylinders, the connecting frame, support hydraulic cylinders and foot pads are combined to form a telescopic support assembly. When the telescopic support is extended, the telescopic support assembly is supported on the ground, while the support base, tracked walking assembly and other components are suspended in the air, providing a stable working environment for the guide drill rod of the horizontal directional drilling rig. When the telescopic support assembly is shortened, the walking device is supported on the bottom surface and can drive the frame assembly and other components to move. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0031] Please refer to Figures 1-6. In this embodiment of the invention, a guide drill rod for a horizontal directional drilling rig includes: a concave frame 15; a motor 17 is fixedly connected inside the positive end of the concave frame 15, and the output shaft of the motor 17 passes through the front end of the concave frame 15 and is fixedly connected to an adjusting bracket 16. The motor 17 can adjust the connection angle between the concave frame 15 and the adjusting bracket 16, thereby changing the drilling angle and enabling smoother drilling during operation, thus improving the performance of the drilling rig.

[0032] Please refer carefully to Figures 2-6. The top of the adjusting bracket 16 is movably connected to a positioning frame 18. A mounting frame 19 is fixedly connected to the upper left side of the positioning frame 18. A drive motor 23 is fixedly connected to the center of the mounting frame 19. A sleeve 28 is fixedly connected to the output shaft of the drive motor 23. A drill rod 27 is magnetically connected to the inner cavity of the sleeve 28. A moving groove 20 is provided on the upper right side of the positioning frame 18. A moving frame 31 is slidably connected inside the moving groove 20. A sealing ring 30 is fixedly connected to the center of the moving frame 31. The inner wall of the sealing ring 30 is movably connected to the outer wall of the drill rod 27. The rotation of the drill rod 27... The force is provided by the drive motor 23, thus changing the original drilling gear driving the mandrel to rotate. The mandrel then transmits the rotational power to the mandrel and coupling inside the steel pipe, causing the drill pipe 27 to rotate. The force transmission is more direct, and there is no leakage in the middle, ensuring the stable and continuous operation of the drill pipe 27 and improving drilling efficiency. In addition, the connection between the drill pipe 27 and the drive motor 23 is through the intervention of the sleeve 28. The drill pipe 27 and the sleeve 28 generate magnetic attraction, which not only ensures the connection is firm and the operation is stable, but also facilitates the replacement of worn drill pipe 27. This makes the drilling rig more smooth and convenient to use, further improving the utilization rate of the drilling rig.

[0033] The working principle of this invention is as follows: the drill rod 27 is inserted into the sealing ring 30, the moving frame 31 slides to the left along the moving groove 20 set in the positioning frame 18, and the drill rod 27 is precisely inserted into the sleeve 28, so that the drill rod 27 rotates synchronously with the drive shaft of the drive motor 23. In addition, the moving frame 31 slides to the right along the moving groove 20 set in the positioning frame 18, and the drill rod 27 is removed from the magnetic range of the sleeve 28, so that the worn drill rod 27 can be taken out from the sealing ring 30 for replacement, making the drilling rig more smooth and convenient to use, and further improving the utilization rate of the drilling rig.

[0034] In other embodiments of the present invention, a reduction motor 25 and a connecting block 22 are fixedly connected to the back of the adjusting bracket 16, and a driving bolt 26 is rotatably connected to the center of the connecting block 22. The left side of the driving bolt 26 is fixedly connected to the output shaft of the reduction motor 25. The connecting block 22 is located on the right side of the rear end of the adjusting bracket 16, and the reduction motor 25 is located on the left side of the rear end of the adjusting bracket 16. In addition, the center of the reduction motor 25 and the center of the connecting block 25 are symmetrically arranged, so the driving bolt 26 rotates horizontally, which plays a crucial role in the subsequent adjustment of the stability of the positioning frame 18.

[0035] Please refer carefully to Figures 2-6. Since the outer wall of the drive bolt 26 is threaded with a sliding bracket 24, a groove 21 is formed on the back of the adjusting bracket 16 from the outside in. One end of the sliding bracket 24 is movably connected to the groove 21 of the drive bolt 26. The sliding bracket 24 is disposed within the groove 21, with a small portion of its rear end exposed outside the adjusting bracket 16. The horizontal movement direction of the sliding bracket 24 within the groove 21 is controlled by the drive bolt 26, and the rotation direction of the drive bolt 26 is controlled by the reduction motor 25. A connecting bracket is fixedly connected to one end of the sliding bracket 24 in the groove 21. 29. The top of the connecting frame 29 is fixedly connected to the bottom of the positioning frame 18. The connecting frame 29 moves around the upper groove of the adjusting bracket 16 and acts as a series connector, causing the sliding frame 24 to connect with the positioning frame 18. Therefore, the moving direction of the sliding frame 24 directly controls the moving direction of the positioning frame 18, thereby adjusting the position of the positioning frame 18 on the adjusting bracket 16. The drill rod 27 moves smoothly with the adjustment of the positioning frame 18, achieving the function of changing positions, so that drilling can be performed more smoothly during operation, improving the use effect of the drilling machine.

[0036] The working principle of this invention is as follows: The lower part of the positioning frame 18 is sequentially connected to the connecting frame 29 and the sliding frame 24. The moving direction of the sliding frame 24 directly controls the moving direction of the positioning frame 18. The moving direction of the sliding frame 24 is controlled by the driving bolt 26, and the direction of the driving bolt 26 is controlled by the reduction motor 25. Therefore, the moving direction of the sliding frame 24 directly controls the moving direction of the positioning frame 18, thereby adjusting the position of the positioning frame 18 on the adjusting bracket 16. The drill rod 27 moves smoothly with the adjustment of the positioning frame 18, thus adjusting the length of the drill rod 27 extending out of the adjusting bracket 16, making it easier to drill during operation and improving the use effect of the drilling machine.

[0037] In other embodiments of the present invention, a fixed frame 13 and a support frame 14 are fixedly connected to the upper and lower ends of the concave frame 15, respectively. A drive frame 8 is fixedly connected to the left side of both the fixed frame 13 and the support frame 14. A traction frame 10 is fixedly connected to the front of the drive frame 8. The fixed frame 13 and the support frame 14 are respectively located at the upper and lower ends of the left side of the concave frame 15, which can not only support the concave frame 15, but also ensure the stability of the concave frame 15 during subsequent lifting and lowering, thereby improving the drilling stability and drilling guidance level of the drilling rig.

[0038] Please refer to Figures 1-3. The drive frame 8 has an adjusting bolt 12 threaded to its center. A servo motor 7 is fixedly connected to the top of the adjusting bolt 12. A vertical support 6 is fixedly connected to the outer wall of the servo motor 7. The drive frame 8 is located on the left side of both the fixed frame 13 and the support frame 14. The adjusting bolt 12 allows the drive frame 8 to move up and down on the vertical support 6. Furthermore, the direction of rotation of the adjusting bolt 12 is controlled by the servo motor 7. Therefore, the user can control the direction of movement of the drive frame 8 and control the raising and lowering of the drill rod 27, achieving the desired angle adjustment. The vertical support 6 has a drive groove 9 and a traction groove 11 at both the upper and lower ends. The outer wall of the drive frame 8 is movably connected to the drive groove 9. The traction frame 10 is movably connected to the traction groove 11 at one end of the drive frame 8. The traction frame 10 is located on the front of the drive frame 8 and moves stably around the traction groove 11. Therefore, the drive frame 8 moves synchronously and stably within the drive groove 9. The adjusting bolt 12 can stably control the lifting and lowering of the drive frame 8.

[0039] The working principle of this invention is as follows: the top left side of the concave frame 15 is connected to the bottom of the fixed frame 13, the bottom left side of the concave frame 15 is connected to the top of the support frame 14, and the drive frame 8 is respectively set on the left side of the fixed frame 13 and the support frame 14. The traction frame 10 is set on the front side of the drive frame 8. The traction frame 10 moves stably around the traction groove 11. Therefore, the drive frame 8 moves synchronously and stably within the drive groove 9. The adjusting bolt 12 can stably control the lifting and lowering of the drive frame 8. The direction of the adjusting bolt 12 is controlled by the servo motor 7, so the lifting and lowering of the drill rod 27 can be controlled.

This provides support for the drilling without affecting the positional movement of the drilling. The tracked walking assembly 2 includes a track, track wheels, a track frame, and a drive motor. The track wheels are rotatably fitted onto the track frame and driven to rotate by the drive motor. The track wheels are sprockets that drive the track to rotate and move. The track frame can serve as a base, which is fixedly connected to both ends of the support base 1. The track consists of track plates, track chains, and pins. The tracked walking device is a mature existing technology and will not be described in detail. The tracked walking structure can adapt to complex terrain and working environment downhole, improving the applicable working conditions range of the drill pipe conveying device.
