Description
Technical Field
[0001] This utility model relates to the field of drill pipe cleaning technology, specifically a device for cleaning drill pipes during surface directional drilling. Background Technology
[0002] In surface directional drilling operations, the drill pipe, as a key component connecting the drill bit and the drill pipe drive unit, is responsible not only for transmitting driving and rotational forces but also for withstanding the complex underground environment and the influence of drilling fluids. Therefore, during the drilling process, a large amount of mud, debris, and other impurities often adhere to the drill pipe surface. These deposits not only increase the weight of the drill pipe but can also cause corrosion and wear, thus affecting its service life and drilling efficiency. More seriously, the mud and impurities adhering to the drill pipe can also be carried into the drilling fluid, adversely affecting its performance and further hindering the normal progress of drilling operations.
[0003] However, traditional drill pipe cleaning methods mainly rely on manual cleaning using tools such as mud scrapers, which is not only inefficient but also often unsatisfactory in cleaning results. Mud and impurities may still remain on the drill pipe surface. In addition, during manual cleaning, drillers are prone to getting mud on their hands, which not only increases their workload but also poses a potential threat to their health. To address these issues, the inventors have proposed a device for cleaning drill pipes during directional drilling on the surface. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-5As shown, this utility model provides a device for cleaning drill rods during directional drilling on the surface. It includes a base 1 and a drill rod 12.

A scraping component 3 is provided on the mounting frame 2 for scraping and cleaning the drill rod 12. A cleaning component 4 is provided on the mounting frame 2 and above the scraping component 3 for rinsing the drill rod 12. A drive component 5 is provided on one side of the mounting frame 2 for driving the scraping component 3 and the cleaning component 4 to work.
[0021] The coating assembly 3 includes a rotating ring 31, which is rotatably connected to the top of the mounting bracket 2. A threaded rod 32 is rotatably connected to one side of the top of the rotating ring 31. An annular plate 33 is threadedly connected to the outer side of the threaded rod 32. Three sets of centrally symmetrically distributed cross rods 34 are arranged between the annular plate 33 and the rotating ring 31. A push plate 35 is rotatably connected to the side of the cross rod 34 near the drill rod 12. A scraper 37 is fixedly connected to the side of the push plate 35 near the drill rod 12. The side of the scraper 37 away from the push plate 35 is in contact with the side of the drill rod 12.
[0022] By adopting the above technical solution, rotating the threaded rod 32 causes the annular plate 33 to move vertically relative to the rotating ring 31, and at the same time causes the cross rod 34 to rotate. The distance between the scraper 37 and the drill rod 12 is adjusted according to the diameter of the drill rod 12, so that the scraping surface of the scraper 37 is in contact with the outer side of the drill rod 12, which further improves the application range of the equipment.
[0023] The cleaning assembly 4 includes a retaining ring 41, which is connected to the mounting bracket 2 via a frame 6. The top of the retaining ring 41 is rotatably connected to an annular tube 42. The inner side of the annular tube 42 is fixedly connected to nozzles 43 that are centrally symmetrically distributed. The nozzles 43 are angled downwards. One side of the annular tube 42 is fixedly connected to a water inlet pipe 44 that communicates with the inside of the annular tube 42. The other end of the water inlet pipe 44 is fixedly connected to a flexible hose 11.
[0024] By adopting the above technical solution, the drill rod 12 is set up to rinse the surface of the drill rod 12. At the same time, the annular pipe 42 swings back and forth along the top of the fixed ring 41, driving the nozzle 43 to swing back and forth, so as to achieve a comprehensive cleaning of the side of the drill rod 12.
[0025] The drive assembly 5 includes a gear ring 51, which is fixedly connected to the outside of the rotating ring 31. A servo motor 52 is fixedly mounted on one side of the mounting bracket 2. A gear 53 is fixedly connected to the outside of the drive end of the servo motor 52. The gear 53 meshes with the gear ring 51. An extension rod 54 is fixedly connected to the drive end of the servo motor 52. A fixing rod 55 is fixedly connected to the top of the extension rod 54. A guide post 56 is fixedly connected to one side of the top of the fixing rod 55. A connecting plate 57 is fixedly connected to the bottom end of the water inlet pipe 44. A guide groove 58 is provided on the connecting plate 57. The guide post 56 is movably engaged in the guide groove 58.
[0026] By adopting the above technical solution, the servo motor 52 drives the gear 53 to rotate, and the gear 53 meshes with the gear ring 51. At the same time, the gear ring 51 and the rotating ring 31 rotate along the top of the mounting frame 2, thereby driving the scraping assembly 3 to rotate along the outside of the drill rod 12 to scrape the mud adhering to the surface of the drill rod 12. At the same time, the fixed rod 55 and the guide post 56 rotate. By utilizing the cooperation between the guide post 56 and the connecting plate 57, the annular pipe 42, the nozzle 43 and the water inlet pipe 44 are driven to periodically reciprocate, so as to achieve comprehensive cleaning of the surface of the drill rod 12.
[0027] Two compensating rods 7 are fixedly connected to the side of the mounting plate 36 near the push plate 35. The end of the compensating rod 7 away from the mounting plate 36 extends movably to the side of the push plate 35 and is fixedly connected to a limit block 9.
[0028] By adopting the above technical solution and setting the limit block 9, the movement of the compensation rod 7 can be limited, preventing the compensation rod 7 from being pulled out from the inside of the push plate 35.
[0029] Two springs 8 are provided between the side of the mounting plate 36 away from the scraper 37 and the push plate 35. The springs 8 are movably sleeved on the outside of the corresponding compensation rod 7.
[0030] By adopting the above technical solution and setting the spring 8, the displacement of the scraper 37 can be compensated, so that the scraper 37 and the outer side of the drill rod 12 have a better fit.
[0031] A guide wheel 10 is rotatably connected to the bottom end of the mounting plate 36 near the drill rod 12, and the side of the guide wheel 10 is in contact with the side of the drill rod 12.
[0032] By adopting the above technical solution, when the guide wheel 10 comes into contact with the variable diameter section of the drill rod 12, the guide wheel 10 guides the movement of the frame 6, thereby avoiding the problem of the drill rod 12 getting stuck when lifting the drill.
[0033] Two guide rods 38 are fixedly connected to the top of the rotating ring 31, and the annular plate 33 is slidably engaged between the outer sides of the guide rods 38.
[0034] By adopting the above technical solution and setting the guide rod 38, the movement of the annular plate 33 can be guided, thereby improving the stability of the annular plate 33 during movement.
[0035] Working principle: When lifting the drill rod 12, the mounting bracket 2 is placed on the top outer side of the drill rod 12, and the threaded rod 32 is rotated to drive the annular plate 33 to move vertically relative to the rotating ring 31, while the cross rod 34 is rotated. The distance between the scraper 37 and the drill rod 12 is adjusted according to the diameter of the drill rod 12 so that the scraping surface of the scraper 37 is in contact with the outer side of the drill rod 12.
[0036] During the drilling process, the servo motor 52 drives the gear 53 to rotate. The gear 53 meshes with the gear ring 51, which in turn drives the gear ring 51 and the rotating ring 31 to rotate along the top of the mounting frame 2. This causes the scraping assembly 3 to rotate along the outside of the drill rod 12, scraping the mud adhering to the surface of the drill rod 12 to achieve initial cleaning of the surface of the drill rod 12. At the same time, when the gear 53 rotates, it drives the fixed rod 55 and the guide post 56 to rotate. Utilizing the cooperation between the guide post 56 and the connecting plate 57, it also drives the annular pipe 42, the nozzle 43, and the water inlet pipe 44 to oscillate periodically, achieving comprehensive cleaning of the surface of the drill rod 12.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
