Description
Technical Field
[0001] This utility model relates to the field of drilling equipment technology, specifically to a high-efficiency drill rod cleaning device. Background Technology
[0002] Drill pipe, as a core tool in drilling operations, is a key component connecting surface equipment and the bottom-hole drilling rig, and its performance directly affects drilling efficiency and safety. Structurally, drill pipe consists of a threaded steel tube at the end, connected end-to-end by a threaded joint to form a drill string. Drill pipe is generally made of high-strength alloy steel, with its mechanical properties improved through normalizing and tempering or quenching and tempering treatments. To address the friction and wear issues between the drill string and the borehole wall, the surface of the drill pipe undergoes high-frequency quenching treatment, with the hardened layer depth strictly controlled within 1 mm to avoid a decrease in fatigue resistance. For special working conditions, composite material drill pipes are gradually becoming a trend. Combining the advantages of metallic and non-metallic materials, they maintain high strength while reducing weight, making them suitable for extreme environments such as deep-sea drilling. Drill pipes are exposed to harsh environments such as moisture or corrosion for extended periods during drilling; therefore, they need to be cleaned after use to prevent strength reduction due to rust or corrosion.
[0003] Currently, cleaning drill pipes requires manual hand-held cleaning brushes to clean the outer wall of the drill pipe, which is inefficient and makes it difficult to achieve comprehensive cleaning, thus affecting the cleaning effect. 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] Please see Figure 1-4 The high-efficiency drill pipe cleaning device of this embodiment includes a frame 1. A motor 5 is fixedly connected to the bottom inner side of the frame 1. A drive wheel 6 is fixedly connected to the shaft of the motor 5. A pair of mounting seats 7 are fixedly connected to the top of the frame 1. A cleaning shaft 8 is rotatably connected between the pair of mounting seats 7. A driven wheel 9 is fixedly connected to the end of the cleaning shaft 8 facing the drive wheel 6. A transmission belt 10 is sleeved between the drive wheel 6 and the driven wheel 9. A mounting plate 12 is fixedly connected to the end of the cleaning shaft 8 away from the driven wheel 9. A through hole 11 is opened at the axis of the cleaning shaft 8. The side wall edge of the mounting plate 12 away from the cleaning shaft 8 is surrounded. The cleaning shaft 8 is evenly provided with several cleaning mechanisms 13 for cleaning the surface of the drill rod. Each cleaning mechanism 13 includes a connecting plate 1301. A movable plate 1302 is detachably provided on the side wall of the connecting plate 1301. A pair of movable shafts 1305 are slidably connected to the side wall of the movable plate 1302 facing the axis of the cleaning shaft 8. A cleaning disc 1306 is rotatably connected to the other end of the movable shaft 1305. A movable groove 1303 is provided at the connection between the connecting plate 1301 and the movable plate 1302. A bolt assembly 1304 is detachably provided between the movable plate 1302 and the movable groove 1303. During cleaning, the drill rod is clamped by the clamping mechanism to keep it coaxial with the cleaning shaft, and then the end of the drill rod is inserted between the cleaning mechanisms 13. At this time, the position of the movable plate 1302 on the side wall of the connecting plate 1301 is adjusted so that the cleaning disc 1306 moves to contact the outer side wall of the drill rod, and then the movable plate 1302 is fixed by the bolt assembly 1304. Then the motor 5 is started so that the drive wheel 6 starts to rotate. When the drive wheel 6 rotates, it drives the driven wheel 9 and the cleaning shaft 8 to rotate through the transmission belt 10. When the cleaning shaft 8 rotates, it drives the mounting plate 12 and the cleaning disc 1306 to rotate, cleaning the surface of the drill rod. During the cleaning process, the drill rod is driven to move into the through hole 11 at the axis of the cleaning shaft 8 through the clamping mechanism, so that the surface of the drill rod can be automatically cleaned in all directions, effectively improving cleaning efficiency and cleaning effect.
[0021] Each movable shaft 1305 has a slider 1307 fixedly connected to one end facing the movable plate 1302. The movable plate 1302 is rotatably connected to both ends of the side away from the cleaning disc 1306 by a two-way lead screw 1308. A pair of sliders 1307 are symmetrically threaded to both sides of the two-way lead screw 1308. The sliders 1307 are slidably connected to the movable plate 1302. The end of the two-way lead screw 1308 away from the connecting plate 1301 is fixedly connected to a handle 1309. A telescopic sleeve is horizontally connected between adjacent movable shafts 1305. The two-way lead screw 1308 and the telescopic sleeve are arranged parallel to the cleaning shaft 8. Before cleaning, adjust the spacing between the cleaning brushes 1306 according to the degree of dirt on the drill rod surface. During adjustment, turn the handle 1309 to start rotating the bidirectional lead screw 1308. When the bidirectional lead screw 1308 rotates, it drives the sliders 1307 on both sides to move accordingly, causing the spacing between the movable shaft 1305 and the cleaning disc 1306 to change accordingly. When the dirt on the drill rod surface is deeper, the spacing between the cleaning discs 1306 is smaller, and the drill rod moves faster, improving the cleaning effect. When the dirt on the drill rod surface is shallower, the spacing between the cleaning discs 1306 is larger, and the drill rod moves slower, which can improve the cleaning speed while ensuring the cleaning quality.
[0022] Several bases 3 are fixedly connected to the bottom of the frame 1, and a top cover 2 is detachably installed on the top of the frame 1. A pair of handrails 4 are symmetrically fixedly connected to the top of the side wall of the frame 1. The top cover 2 can protect the cleaning shaft 8, and the handrails 4 and bases 3 can support the frame 1 and reduce the vibration generated by the motor 5 during cleaning.
[0023] Working principle: During cleaning, the drill rod is clamped by the clamping mechanism, keeping the drill rod and the cleaning shaft coaxial. Then, the end of the drill rod is inserted between the cleaning mechanisms 13. At this time, the position of the movable plate 1302 on the side wall of the connecting plate 1301 is adjusted so that the cleaning disc 1306 moves to contact the outer side wall of the drill rod. The movable plate 1302 is then fixed by the bolt assembly 1304. Then, the motor 5 is started, causing the drive wheel 6 to start rotating. When the drive wheel 6 rotates, it drives the driven wheel 9 and the cleaning shaft 8 to rotate through the transmission belt 10. When the cleaning shaft 8 rotates, it drives the mounting plate 12 and the cleaning disc 1306 to rotate accordingly, cleaning the surface of the drill rod. During the cleaning process, the clamping mechanism drives the drill rod to move into the through hole 11 at the axis of the cleaning shaft 8, thereby achieving all-round automatic cleaning of the surface of the drill rod, effectively improving cleaning efficiency and cleaning effect.
[0024] Before cleaning, adjust the spacing between the cleaning brushes 1306 according to the degree of dirt on the drill rod surface. During adjustment, turn the handle 1309 to start rotating the bidirectional lead screw 1308. When the bidirectional lead screw 1308 rotates, it drives the sliders 1307 on both sides to move accordingly, causing the spacing between the movable shaft 1305 and the cleaning disc 1306 to change accordingly. When the dirt on the drill rod surface is deeper, the spacing between the cleaning discs 1306 is smaller, and the drill rod moves faster, improving the cleaning effect. When the dirt on the drill rod surface is shallower, the spacing between the cleaning discs 1306 is larger, and the drill rod moves slower, which can improve the cleaning speed while ensuring the cleaning quality.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
