Description

Technical Field

[0001] The invention belongs to the technical field of drill rod joints, in particular to a novel high-torsion-resistant drill rod joint. Background Art

[0002] A drill pipe joint is a mechanical connector used to connect multiple drill pipes together to form a continuous drill string. It is used to transmit torque, withstand axial forces, and transport drilling mud to the drill bit during the drilling process. It is a key component of drilling equipment, ensuring that the drill pipe can work stably and continuously.

[0003] The patent with announcement number CN216240476U discloses a high-torsion drill pipe joint for mining, which relates to the technical field of drill pipe joints. The patent includes a drill pipe joint body, which is composed of a threaded section, an intermediate section and a tail section in sequence. The tail section is provided with an internal thread, and the outer surface of the threaded section is provided with an external thread. The circumference of the intermediate section is provided with an annular groove, and two annular slides and a runner are provided in the annular groove, and one runner is provided in the center of the two annular slides. The patent uses a runner with a diamond cutter head on the outer periphery of the intermediate section to rotate in the annular slide. Since the diamond cutter head is hard in texture, it can increase the friction between the drill pipe joint body and the rock chips during rotation, improve the ability to remove rock chips, and prevent rock chips from wearing the drill pipe joint body, thereby extending the service life of the joint. It can reduce the resistance of the rock, mud and soil layers to the drill pipe joint body during mining, and avoid deformation caused by excessive torque.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Since the drill rod joint is provided with a threaded section, when multiple drill rod joints are stacked together, the threaded section is easily damaged by collision, thereby affecting the firmness of its subsequent installation. In addition, under normal circumstances, the surface of the drill rod joint may have defects after being used for a period of time. Therefore, before using the drill rod joint, workers are required to conduct a visual inspection of its surface to determine whether the drill rod joint can continue to be used. When multiple drill rod joints are stacked together, it is not conducive to the inspection of workers and it is easy to get confused. In addition, each time the drill rod joint is inspected, the drill rod joint needs to be rotated to observe the various positions of the drill rod joint. Frequent rotation of multiple drill rod joints will also cause fatigue to the workers.

[0006] To this end, the present invention provides a novel high-torsion resistance drill pipe joint. Summary of the Invention

[0019] Preferably, the tube body is made of alloy steel.

[0020] Preferably, a mounting ring is sleeved on the outer ring of the tube body and mounted via bolts, and a plurality of diamond cutter heads are arranged on the surface of the mounting ring.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The novel high-torsion-resistant drill pipe joint described in the present invention utilizes a protective shell to cover the threaded section of the pipe body, thereby preventing the threaded section from being damaged due to collision when multiple pipe bodies are placed together, thereby affecting the firmness of subsequent pipe body connections. In addition, by utilizing a multi-section connection mechanism and a synchronous rotation component, when it is necessary to visually inspect the surfaces of multiple pipe bodies placed together, multiple protective shells are connected together by inserting the protruding block rod into the inner cavity of the remaining groove cylinders, and inserting the plug into the jacks of the connecting block 1 and the connecting block 2. The staff only needs to rotate the groove cylinder on any side to make the multiple groove cylinders, worm gear, protruding block rod, and turntable rotate synchronously, and the pipe body When the protective shell rotates in the inner cavity, the staff can see the surface of the tube through the protective shell to conduct quality inspection work. Moreover, since multiple tubes can rotate synchronously, there is no need to frequently rotate multiple tubes in sequence to see the various positions of the tubes, which reduces the inspection intensity of the workers. Moreover, the tubes are arranged in order and it is not easy to cause confusion during inspection. Moreover, when the tubes are placed into the protective shell, the positioning groove and the positioning rod cooperate with each other to make each tube in the inner cavity of the protective shell at the same angle. When multiple tubes rotate in unison, workers can use the positioning groove as a reference standard to record the positions of defects on the surface of the tubes in sequence, which is less likely to cause confusion in records.

[0023] 2. The novel high-torsion-resistant drill pipe joint described in the present invention has a pipe body made of alloy steel. Therefore, the pipe body has high strength and good toughness, and can withstand large torque without being easily broken.

[0024] 3. The novel high-torsion-resistant drill pipe joint described in the present invention has multiple diamond cutter heads arranged on the surface of the mounting ring. Due to the hard texture of the diamond cutter heads, when the diamond cutter heads rotate, they can significantly improve cutting efficiency and increase the friction between the drill pipe joint body and rock cuttings. At the same time, during the drilling process, the diamond cutter heads can more effectively remove rock cuttings and shavings to prevent them from clogging the drill hole or wearing the drill pipe joint body, helping to keep the drill hole clean and smooth, and improving drilling quality and efficiency.

[0041] In this embodiment, Figures 1-9 As shown, a second spring 24 is sleeved on one side of the second slide rod 23 , one end of the second spring 24 is fixedly connected to the insert block 22 , and the other end is fixedly connected to the outer wall of the protective shell 1 .

[0042] One end of the positioning plate 14 is threadedly connected to the bidirectional threaded rod 13 , and both ends of the bidirectional threaded rod 13 are rotatably disposed on the turntable 5 .

[0043] One end of the bidirectional threaded rod 13 is fixedly connected to a knob 29 , and the surface of the knob 29 is provided with an anti-slip texture.

[0047] A torsion spring 26 is sleeved on one side of the rotating shaft 25 , and the torsion spring 26 is used to reset the rotating shaft 25 .

[0048] Specifically, existing drill rod joints are usually provided with threaded sections 3. When multiple drill rod joints are stacked together, the threaded sections 3 are easily damaged due to collision, thereby affecting the firmness of their subsequent installation. In addition, under normal circumstances, after a period of use, the surface of the drill rod joint may have defects. Therefore, before using the drill rod joint, workers are required to visually inspect its surface to determine whether the drill rod joint can continue to be used. When the drill rod joints are stacked together, it is not convenient for workers to inspect and it is easy to get confused. In addition, each time the drill rod joint is inspected, it is necessary to rotate the drill rod joint to observe the various positions of the drill rod joint. Frequent rotation of multiple drill rod joints will also cause fatigue to the workers.

[0049] Therefore, in order to solve the above problem, in this embodiment, when in use, the threaded section 3 and the internal thread 10 are used to connect multiple pipe bodies 2 together to meet the actual required length and facilitate achieving the required drilling depth;

[0050] When placing the tube body 2, the tube body 2 can be placed into the protective shell 1, and the end with the internal thread 10 is fitted with the turntable 5. Then, the handle 29 is manually turned to make the two positioning plates 14 slide away from each other at the same time and fit with the inner wall of the tube body 2, so that the tube body 2 can be fixed. Then, under the action of the torsion spring 26, the shell cover 4 covers the end of the protective shell 1, thereby achieving a protective effect on the threaded segment 3 and avoiding the situation where the threaded segment 3 is damaged due to collision when multiple tube bodies 2 are placed together, thereby affecting the firmness of the subsequent connection of the tube bodies 2.

[0051] When it is necessary to visually inspect the surfaces of multiple tube bodies 2 placed together, multiple protective shells 1 can be connected together by inserting the protruding rod 8 into the inner cavity of the remaining groove cylinder 7. When the protruding rod 8 is inserted into the inner cavity of the remaining groove cylinder 7, the plug 22 is moved to remove it from the socket 28 of the connecting block 21. When the connecting block 21 is fitted with the connecting block 1 20 on the remaining protective shell 1, the plug 22 is loosened, and the plug 22 can be inserted into the two sockets 28 under the action of the spring 24, so that the connecting block 1 20 and the connecting block 2 21 can be connected together, and then repeated multiple times. Multiple protective shells 1 can be connected together in an arranged manner. At this time, the staff only needs to rotate the groove cylinder 7 on any side to make the multiple groove cylinders 7, the worm 6, and the protruding rod 8 rotate simultaneously, and the multiple turntables 5 also rotate synchronously. At this time, the tube body 2 rotates in the inner cavity of the protective shell 1, and the staff can see the surface of the tube body 2 through the protective shell 1. Moreover, since the multiple tube bodies 2 can rotate synchronously, there is no need to frequently rotate the multiple tube bodies 2 in sequence to see each position of the tube body 2, which reduces the inspection intensity of the workers. In addition, the tube bodies 2 are arranged in order and it is not easy to be confused during inspection.

[0052] When it is found that the tube body 2 has quality defects, the staff needs to record the defect position for subsequent processing. However, since the angle of each tube body 2 when it is inside the protective shell 1 is different, it is not easy to find a reference standard to record the defect position, and confusion in recording is likely to occur. Therefore, in order to avoid this problem, when the tube body 2 is placed into the protective shell 1, the positioning groove 11 of the tube body 2 is aligned with the positioning rod 19, and then the push block 16 is pushed to insert the positioning rod 19 into the positioning groove 11. At this time, the tube body 2 is slid into the inside of the protective shell 1. When the tube body 2 is positioned by the positioning plate 14, the push block 16 is released, and the positioning rod 19 is reset under the action of the spring 17. Through the above operation, each tube body 2 in the inner cavity of the protective shell 1 can be at the same angle. When multiple tube bodies 2 are rotated uniformly, workers can use the positioning groove 11 as a reference standard to record the position of surface defects of the tube body 2, and confusion in recording is not likely to occur.

[0053] In this embodiment, Figure 1 As shown, the tube body 2 is made of alloy steel.

[0054] Specifically, since the tube body 2 is made of alloy steel, the tube body 2 has high strength and good toughness, and can withstand large torque without being easily broken.

[0055] In this embodiment, Figure 1 As shown, a mounting ring 12 is sleeved on the outer ring of the tube body 2 and mounted via bolts, and a plurality of diamond bits 27 are provided on the surface of the mounting ring 12 .

[0056] Specifically, when the tube body 2 rotates, the diamond cutter head 27 is hard in texture. Therefore, when the diamond cutter head 27 rotates, the cutting efficiency can be significantly improved, and the friction between the drill pipe joint body and the rock chips can be increased. At the same time, during the drilling process, the diamond cutter head 27 can more effectively remove rock chips and cuttings to prevent them from clogging the drill hole or wearing the drill pipe joint body, which helps to keep the drill hole clean and smooth, and improve the drilling quality and efficiency.

[0057] Working principle: Utilize the threaded section 3 and the internal thread 10 to connect multiple pipe bodies 2 together to meet the actual required length and facilitate the achievement of the required drilling depth. Since the pipe body 2 is made of alloy steel, the pipe body 2 has high strength and good toughness and can withstand large torque without breaking easily. When the pipe body 2 rotates, the diamond cutter head 27 is hard in texture. Therefore, when the diamond cutter head 27 rotates, it can significantly improve the cutting efficiency and increase the friction between the drill pipe joint body and the rock cuttings. At the same time, during the drilling process, the diamond cutter head 27 can more effectively remove rock cuttings and cuttings to prevent them from clogging the drill bit. The hole or wear of the drill pipe joint body helps to keep the drill hole clean and smooth, and improve the drilling quality and efficiency. When the pipe body 2 is placed, the pipe body 2 can be placed in the protective shell 1, and the end with the internal thread 10 is fitted with the turntable 5, and then the screw handle 29 is manually turned to make the two positioning plates 14 slide away from each other at the same time and fit with the inner cavity wall of the pipe body 2, so that the pipe body 2 can be fixed. Then, under the action of the torsion spring 26, the shell cover 4 covers the end of the protective shell 1, thereby achieving a protective effect on the threaded section 3, avoiding damage to the threaded section 3 due to collision when multiple pipe bodies 2 are placed together, thereby affecting the subsequent pipe When it is necessary to visually inspect the surfaces of multiple tube bodies 2 placed together, multiple protective shells 1 can be connected together by inserting the protruding rod 8 into the inner cavity of the remaining groove cylinder 7, and when the protruding rod 8 is inserted into the inner cavity of the remaining groove cylinder 7, the plug 22 is moved to move it out of the socket 28 of the connecting block 21. When the connecting block 21 is fitted with the connecting block 1 20 on the remaining protective shell 1, the plug 22 is loosened, and the plug 22 can be inserted into the two sockets 28 under the action of the spring 24, so that the connecting block 1 20 and the connecting block 2 21 can be connected together, and then After repeating this process several times, multiple protective shells 1 can be connected together in an arranged manner. At this time, the staff only needs to rotate the groove cylinder 7 on any side to make the multiple groove cylinders 7, the worm 6, and the protruding rod 8 rotate simultaneously, and the multiple turntables 5 also rotate synchronously. At this time, the tube body 2 rotates in the inner cavity of the protective shell 1, and the staff can see the surface of the tube body 2 through the protective shell 1. Moreover, since the multiple tube bodies 2 can rotate synchronously, there is no need to frequently rotate the multiple tube bodies 2 in sequence to see each position of the tube body 2, which reduces the inspection intensity of the workers. In addition, the tube bodies 2 are arranged in order and it is not easy to be confused during inspection.When a quality defect is found in the tube body 2, the staff needs to record the defect location for subsequent processing. However, since the angle of each tube body 2 when it is inside the protective shell 1 is different, it is not easy to find a reference standard to record the defect location, which easily leads to confusion in the record. Therefore, in order to avoid this problem, when the tube body 2 is placed inside the protective shell 1, the positioning groove 11 of the tube body 2 is aligned with the positioning rod 19, and then the push block 16 is pushed to insert the positioning rod 19 into the positioning groove 11. At this time, the tube body 2 is slid into the protective shell 1. When the tube body 2 is positioned by the positioning plate 14, the push block 16 is released, and the positioning rod 19 is reset under the action of the spring 17. Through the above operation, each tube body 2 in the inner cavity of the protective shell 1 is at the same angle. When multiple tube bodies 2 are rotated uniformly, the worker can use the positioning groove 11 as a reference standard to record the location of the surface defect of the tube body 2, which is less likely to cause confusion in the record.
