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] The drill pipe joint is a mechanical connector used to connect multiple drill pipes together to form a continuous drill string so as to transmit torque, withstand axial force, 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 a drill pipe joint technical field. 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 circumferential side of the intermediate section is provided with an annular groove, and two annular slides and a rotating wheel are provided in the annular groove, and a rotating wheel is provided in the center of the two annular slides. The patent uses a rotating wheel 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 cuttings during rotation, improve the ability to remove the cuttings, and prevent the cuttings from wearing the drill pipe joint body, extending the service life of the joint, and can reduce the resistance of the rock, sand and soil layer 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: Since the drill pipe joint is provided with a threaded section, when multiple drill pipe joints are stacked together, the threaded section is easily damaged by collision, thereby affecting the firmness of its subsequent installation. In addition, usually, after the drill pipe joint has been used for a period of time, there may be defects on its surface. Therefore, before the drill pipe joint is used, workers are required to conduct a visual inspection of its surface to determine whether the drill pipe joint can continue to be used. When multiple drill pipe joints are stacked together, it is not convenient for workers to inspect and it is easy to confuse them. In addition, each time the drill pipe joint is inspected, the drill pipe joint needs to be rotated to observe various positions of the drill pipe joint. Frequent rotation of multiple drill pipe joints will also cause fatigue to the workers.

[0005] To this end, the present invention provides a novel high torsion resistance drill pipe joint. Summary of the invention

[0014] Preferably, a torsion spring is sleeved on one side of the rotating shaft, and the torsion spring is used to reset the rotating shaft.

[0015] Preferably, the tube body is made of alloy steel.

[0016] Preferably, a mounting ring is sleeved on the outer ring of the tube body and installed via bolts, and a plurality of diamond cutter heads are arranged on the surface of the mounting ring.

[0017] The beneficial effects of the present invention are as follows: 1. A novel high-torsion-resistant drill pipe joint described in the present invention can cover the threaded section of the pipe body with a protective shell, 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 using a multi-segment 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, the worm, the protruding block rod, and the 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 body through the protective shell to conduct quality inspection work, and because multiple tube bodies can rotate synchronously, there is no need to frequently rotate multiple tube bodies in sequence to see each position of the tube body, which reduces the inspection intensity of the workers. In addition, the tube bodies are arranged in order and it is not easy to be confused during inspection. Moreover, when the tube body is placed into the protective shell, the positioning groove and the positioning rod cooperate with each other to make each tube body in the inner cavity of the protective shell at the same angle. When multiple tube bodies rotate in unison, the workers can use the positioning groove as a reference standard to record the positions of surface defects of the tube body in sequence, which is not easy to cause confusion in recording.

[0018] 2. The novel high-torsion-resistant drill pipe joint described in the present invention has a pipe body made of alloy steel, so the pipe body has high strength and good toughness and can withstand large torque without being easily broken.

[0019] 3. The novel high-torsion-resistant drill pipe joint described in the present invention has a plurality of diamond cutter heads arranged on the surface of the mounting ring. Since the diamond cutter heads are hard in texture, when the diamond cutter heads rotate, the cutting efficiency can be significantly improved, and the friction between the drill pipe joint body and the rock cuttings can be increased. 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 borehole or wearing the drill pipe joint body, which helps to keep the borehole clean and smooth and improve the drilling quality and efficiency.

[0025] In this embodiment, Figure 1-Figure 9 As shown, a spring 24 is sleeved on one side of the slide rod 23 , one end of the 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 .

[0026] One end of the positioning plate 14 is threadedly connected to a bidirectional threaded rod 13 , and both ends of the bidirectional threaded rod 13 are rotatably disposed on the turntable 5 .

[0031] 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 .

[0032] Specifically, the existing drill pipe joints are usually provided with a threaded section 3, and when multiple drill pipe joints are stacked together, the threaded section 3 is easily damaged due to collision, thereby affecting the firmness of the subsequent installation. In addition, usually, after the drill pipe joints have been used for a period of time, there may be defects on the surface. Therefore, before the drill pipe joints are used, workers are required to visually inspect their surfaces to determine whether the drill pipe joints can continue to be used. When the drill pipe joints are stacked together, it is not convenient for workers to inspect and it is easy to confuse them. In addition, each time the drill pipe joints are inspected, the drill pipe joints need to be rotated to observe the various positions of the drill pipe joints. Frequent rotation of multiple drill pipe joints will also cause fatigue to the workers. Therefore, in order to solve the above problems, in this embodiment, when used, the threaded section 3 and the internal thread 10 are used to connect multiple pipe bodies 2 together to meet the actual required length, so as to achieve the required drilling depth; When placing the tube body 2, the tube body 2 can be placed in the protective shell 1, and one end with the internal thread 10 is fitted with the turntable 5, and 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, and 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, avoiding the situation where the threaded segment 3 is damaged due to collision when multiple tube bodies 2 are placed together, thereby affecting the subsequent connection firmness of the tube body 2; 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 block 22 is moved to be removed from the insertion hole 28 of the connecting block 21. When the connecting block 21 is fitted with the connecting block 1 20 on the remaining protective shells 1, the plug block 22 is loosened, and the plug block 22 can be inserted into the two insertion holes 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. The 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 at the same time, 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. In addition, since the multiple tube bodies 2 can rotate synchronously, it is not necessary 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 an orderly manner, and it is not easy to be confused during inspection. When it is found that the tube body 2 has quality defects, the staff needs to record the defect position for subsequent processing. 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 easy 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 protective shell 1. After 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 rotate uniformly, workers can use the positioning groove 11 as a reference standard to record the position of the surface defects of the tube body 2, and confusion in recording is not easy to occur.

[0033] In this embodiment, Figure 1 As shown, the tube body 2 is made of alloy steel.

[0034] 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.

[0035] In this embodiment, Figure 1 As shown, a mounting ring 12 is sleeved on the outer ring of the tube body 2 and installed by bolts, and a plurality of diamond bits 27 are arranged on the surface of the mounting ring 12 .

[0036] Specifically, when the tube body 2 rotates, since the diamond cutter head 27 is hard in texture, the diamond cutter head 27 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 shavings to prevent them from clogging the borehole or wearing the drill pipe joint body, which helps to keep the borehole clean and smooth and improve the drilling quality and efficiency.

[0037] 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, so as to achieve 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, so 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 the rock cuttings and cuttings to prevent them from clogging the drill. The hole or wear of the drill pipe joint body helps to keep the drilling 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 hand 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, and then under the action of the torsion spring 26, the shell cover 4 covers the end of the protective shell 1, thereby achieving the protection effect of the threaded segment 3, avoiding the damage of the threaded segment 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 block rod 8 into the inner cavity of the remaining groove cylinder 7, and when the protruding block rod 8 is inserted into the inner cavity of the remaining groove cylinder 7, the plug block 22 is moved to be removed from the insertion hole 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 block 22 is loosened, and the plug block 22 can be inserted into the two insertion holes 28 under the action of the spring 24, so that the connecting block 1 20 and the connecting block 21 can be connected together, and then After repeating for 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 block rod 8 rotate at the same time, 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, it is not necessary 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 it is found that the tube body 2 has quality defects, the staff needs to record the defect position for subsequent processing. 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 it is easy to have a confusing 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. After 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, the worker can use the positioning groove 11 as a reference standard to record the position of the surface defects of the tube body 2, and it is not easy to have a confusing record. ;
