Description

Technical Field

[0001] The invention relates to the technical field of drill collar production, in particular to a drill collar thread laser processing device. Background Art

[0002] A drill collar is an engineering tool, usually used for cutting, drilling or grinding on hard materials. It has a wide range of applications in various fields. The standardization of drill collars is the key to ensuring their quality and performance, and is also an important factor in ensuring production efficiency and safety. The drill collar is located at the bottom of the drill string and is the main component of the lower drill bit assembly. The drill collar is provided with threads, which is a threaded drill collar. The threaded drill collar can prevent the differential pressure blockage of the drill bit during the drilling process. The spiral groove allows the mud to flow freely around the drill collar to balance the pressure and prevent the formation of blockage, thereby effectively preventing the occurrence of pressure differential sticking. In order to cut threads on threaded drill collars, one of the common production methods is to cut threads on threaded drill collars using a laser cutting machine, which can greatly improve the production efficiency of threaded drill collars.

[0003] At present, when laser cutting machines perform thread processing on drill collars, they will generate a large amount of dust and exhaust gas. The dust may contain harmful substances such as heavy metals and organic compounds. These exhaust gases and dust are not only harmful to human health, but may also pollute the environment. If dust and exhaust gas cannot be controlled and collected in time, the impact on human health and the working environment will be inevitable.

[0004] Therefore, it is necessary to provide a drill collar thread laser processing device to solve the above technical problems. Summary of the Invention

[0043] In this embodiment

[0044] The side box 37 is pre-filled with an appropriate amount of clean water. Drill collars are pre-fixed on the four transverse plates 12 through two inlet and outlet holes 27. When the drill collars need to be laser processed, the air pump 39 needs to be started first, and then the electric motor 3 17 on the left side is started. The electric motor 3 17 will drive the adapter rod 15 fixed to it, and the adapter rod 15 will drive the clamping block 16 connected to it. Since the two ends of the drill collar are firmly clamped by the two clamping blocks 16, the drill collar is driven by the electric motor 3 17 through the adapter rod 15. The cooperation of the two adapter rods 15 and the two clamping blocks 16 can drive the drill collar to rotate, and then start the electric motor four 20. The electric motor four 20 will drive the threaded rod two 19 fixedly connected to it. During the rotation of the threaded rod two 19, restricted by the two long rods, the connecting block 21 will drive the laser head 22 in the started state to gradually move to the right on the threaded rod two 19. During the movement of the laser head 22, the drill collar in the rotating state will be engraved with threads on the surface by the laser head 22 using laser.

[0045] During the laser processing of the drill collar, debris will be generated and scattered outward. The scattered debris will be gradually sucked into the two suction hoods 26 by the action of the vacuum pump 39, and then enter the bellows 24 through the two extension tubes 25 and a U-shaped tube 23, and flow into the L-shaped tube 38 through the bellows 24. Considering that the two inlet and outlet holes 27 are used for the drill collar to enter and exit the operating box 1, the two inlet and outlet holes 27 sometimes need to be opened for the movement of the drill collar. Therefore, suction hoods 2 35 are fixed on the two baffles 30. The missed debris will be introduced into the two bellows 2 36 through the two suction hoods 2 35, and then collected into the L-shaped tube 38. The air with debris in the L-shaped tube 38 will finally be discharged to the side box 37 through the conveying pipe 40 and mixed with water, so that the debris remains in the water, and the filtered air is discharged outward, completing a round of debris collection and processing.

[0046] After the connecting block 21 drives the laser head 22 to move to the predetermined position, the laser head 22 temporarily stops emitting laser. At this time, the processing of a drill collar has been completed. Then the output shaft of the electric motor 4 20 starts to rotate in the opposite direction, driving the connecting block 21 and the laser head 22 to move to the initial position. Then the electric motor 1 5 is started, and the output shaft of the electric motor 1 5 drives the bevel gear 6 fixedly connected to it. Under the mutual cooperation of the two bevel gears 6, the rotating rod 4 will rotate on the circular block 3, and the rotating rod 4 drives the circular plate 7. Through the circular plate 7, the position of the four drill collars can be adjusted, and the drill collar that has just completed the laser processing will be moved to one side and placed for a while, and the spare drill collar on the side will be moved to the bottom of the laser head 22 for the next round of laser processing.

[0047] When the drill collar that has completed laser processing is driven by the electric motor 5 to the side of the inlet and outlet hole 27 on the right, while other drill collars are being processed, the electric push rod 2 31 on the right is started, and the output rod of the electric push rod 2 31 will gradually output outward, thereby pushing the sliding plate 2 32 to slide downward, and the sliding plate 2 32 drives the rack 33. The rack 33 will drive the set block 45 to rotate counterclockwise with the U-shaped rod 28 as the center through the cooperation of multiple tooth grooves 29. The set block 45 drives the baffle 30 and the frame plate 41, so that the baffle 30 gradually moves away from one side of the operating box 1, and the inlet and outlet hole 27 on the right will gradually lose its obstruction and be in a smooth state. During the rotation of the baffle 30, the suction hood 2 35 is not affected by the bellows 2 36, and continues to absorb air with debris to prevent debris from floating out of the operating box 1.

[0048] Then the electric motor 2 11 on the right side will start, and the output shaft of the electric motor 2 11 will drive the threaded rod 10 fixedly connected thereto. During the rotation of the threaded rod 10, the driving plate 44 will gradually slide to the right on the threaded rod 10 due to the cooperation restriction of the docking rod 1. The driving plate 44 pushes the transverse plate 12, so that the drill collar located on the top of the transverse plate 12 will gradually be moved to the outside of the operating box 1 through the inlet and outlet hole 27 on the right side. After the drill collar is exposed, the corresponding electric push rod 13 will be started again, and the output rod of the electric push rod 13 will gradually output outward. This will drive the sliding plate 14 to slide. During the movement, the sliding plate 14 will drive a connecting rod 15 and a clamping block 16 connected to it away from the drill collar. After one end of the drill collar loses support, it will be removed from the transverse plate 12. After that, the drill collar to be processed is placed on the two clamping blocks 16, and the electric push rod 13 is started again to fix the two ends of the drill collar between the two clamping blocks 16 again. Then, the electric motor 2 11 is started in the opposite direction to move the drill collar back into the operating box 1. The replacement of the drill collar can be completed, ensuring that the drill collar is continuously laser processed in turn.

[0049] Compared with related technologies, the drill collar thread laser processing device provided by the present invention has the following beneficial effects:

[0050] In the present invention, four drill collars that need to be laser processed are set on the circular plate 7. The positions of the four drill collars can be adjusted by the drive of the electric motor 1 5, so that the drill collars can be processed in turn. The four electric motors 2 11 can push the drill collars to slide. After the drill collars are laser processed, they can slide out of the operation box 1 one by one through the access hole 27 under the drive of the electric motor 2 11, so that the drill collars that have been processed can be removed and replaced with the drill collars that need to be processed, ensuring the continuous operation of the equipment and reducing the loss time while completing the replacement of the drill collars, thereby relatively improving the use efficiency of the equipment and being closest to the debris generation area. Two suction hoods 26 are set at the position to collect the debris as soon as possible when the debris is generated. In order to prevent the debris from scattering, two suction hoods 35 are installed on both sides of the operation box 1 to assist in collecting the debris in the operation box 1, thereby reducing the amount of debris in the operation box 1 to a greater extent. The two suction hoods 35 are fixedly connected to the two baffles 30, so that the two suction hoods 35 can always perform adsorption work while the two baffles 30 rotate, preventing the debris from escaping from the operation box 1 through the inlet and outlet holes 27, reducing the impact of the external environment, and controlling the debris in the operation box 1.

[0051] Second embodiment:

[0052] Based on the drill collar thread laser processing device provided in the first embodiment of the present application, the second embodiment of the present application provides another drill collar thread laser processing device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0053] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation plans.

[0054] Please refer to Figure 12-16 In the drill collar thread laser processing device: a lifting mechanism is provided on each of the four transverse plates 12, and each of the four lifting mechanisms includes: a support plate 46, four two-bar blocks 47, two round rods 48, two moving blocks 49, two electric push rods 50, two hinged rods 51, and two square blocks 52. The two support plates 46 are arranged above the corresponding transverse plates 12, and the four strip blocks 47 are fixedly installed on the top of the corresponding transverse plates 12. The four strip blocks 47 correspond to each other in pairs, and the four strip blocks 47 are each provided with a transverse hole. The two round rods 48 are slidably installed on the four strip blocks through the four transverse holes. 47, the two moving blocks 49 are fixedly mounted on the two circular rods 48, the bottoms of the two moving blocks 49 are inlaid with rolling balls three, the two rolling balls three are in contact with the top of the transverse plate 12, the two electric push rods three 50 are arranged on the top of the corresponding transverse plate 12, the output rods of the two electric push rods three 50 are respectively fixedly connected to one side of the two moving blocks 49, the two hinged rods 51 are rotatably mounted on the two moving blocks 49, the two square blocks 52 are fixedly mounted on the bottom of the support plate 46, and the two square blocks 52 are respectively rotatably connected to the two hinged rods 51 at one end away from the two moving blocks 49.

[0055] In this method, in order to ensure the stability of the installation of the electric push rod three 50, the output rod of the electric push rod three 50 is fixedly connected to the predetermined position on the moving block 49, two pads are fixedly installed on the top of the four horizontal plates 12, and two U-shaped clamps six are fixedly installed on the eight pads. Multiple U-shaped clamps six are fixedly connected to the eight electric push rods three 50 respectively, and the top of the four support plates 46 are provided with a placement groove, which is used to place the drill collar to prevent the drill collar from rolling easily on the support plate 46.

[0056] In this embodiment

[0057] In order to facilitate the placement of the drill collar and ensure that the two ends of the drill collar are accurately fitted with the corresponding two clamping blocks 16, when the drill collar is located outside the operating box 1 and needs to be placed, the corresponding two electric push rods 3 50 are started, and the output rods of the two electric push rods 3 50 will be output outward at the same time, pushing the two moving blocks 49 to slide between the four bar blocks 47, and the distance between the two moving blocks 49 will gradually increase. During the movement of the two moving blocks 49, they will produce rotational contact with the two hinged rods 51, and the cooperation of the two square blocks 52 will push the support plate 46, so that the support plate 46 gradually moves upward. After the support plate 46 is moved to an appropriate height, the two electric push rods 3 50 will temporarily stop driving, and the support plate 46 will maintain the same height. Then, the drill collar to be fixed will be placed in the recessed groove on the top of the support plate 46, and then the corresponding electric push rod 13 will be started again to ensure that the drill collar is placed stably, thereby preventing the drill collar from being offset and affecting subsequent laser processing.
