Description

Technical Field

[0001] This utility model belongs to the technical field of drill pipe cleaning equipment, and in particular relates to a drill pipe cleaning device for oil drilling. Background Technology

[0002] After the drill bit is connected to the head of the drill pipe, the other end of the drill pipe is connected to the drilling rig. The drilling rig drives the drill pipe to rotate, and the drill bit drills away rock cuttings. During the drilling process, a large amount of drilling fluid needs to be supplied to the drill bit to ensure the sequential drilling. After the drill pipe is removed, a large amount of drilling fluid and mud adheres to the outer cylindrical surface of the drill pipe, so it needs to be cleaned with a high-pressure cleaner to prepare for the next use. A search revealed that patent application number 202122201245.9 discloses an oil drilling drill pipe cleaning device, including a base. Lockable casters are rotatably installed at the four corners of the bottom of the base. A support is fixedly connected to the top left of the base, and a battery is fixedly connected to the top right of the base. A rectangular tube is fixedly connected to the top left of the support. Two L-shaped tubes are sealed and slidably sleeved inside the rectangular tube. The two L-shaped tubes extend to the outside of the rectangular tube on opposite sides. The two L-shaped tubes are symmetrically arranged, and a connecting pipe is connected and fixed to the left end of each L-shaped tube.

[0003] However, in actual use, the applicant found that the cleaning of drilling pipes is achieved by using long bristles and water spray holes set on the inner wall of the arc-shaped tube. Since only one layer of arc-shaped tube is set along the direction of drill pipe movement, the cleaning of drilling pipes is not sufficient. In view of this, we propose an oil drilling pipe cleaning device. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A drill pipe cleaning device for oil drilling includes a base 1, characterized in that: a frame seat 2 is fixedly connected to the top of the base 1, movable blocks 21 are symmetrically slidably connected to the front side of the frame seat 2, a double-ended screw 22 is rotatably connected to the inside of the frame seat 2 via bearings, the threads at both ends of the double-ended screw 22 have opposite directions, and the two ends of the double-ended screw 22 are respectively threaded through the two movable blocks 21, one end of the double-ended screw 22 extends to the outside of the frame seat 2 and is fitted with an adjusting disc 23, a drill pipe cleaning nozzle 3 is fixedly connected to the front side of the movable block 21, two drill pipe cleaning nozzles 3 are arranged vertically on the front side of the movable block 21, nozzles 31 are evenly arranged on the inner wall of the drill pipe cleaning nozzle 3, and a water inlet branch pipe 32 is provided at the tail end of the drill pipe cleaning nozzle 3. Two side inlet branch pipes 32 are connected through a vertical pipe 6. The lower end of the vertical pipe 6 is connected to the outlet of the booster pump 8 through a connecting hose 7. The booster pump 8 is fixedly installed on the top of the base 1 behind the frame 2. The inlet of the booster pump 8 is connected to an external water supply pipe through a water delivery pipe. The outlet of the booster pump 8 is equipped with two outlet branch pipes. A drill pipe brush holder 4 is fixedly connected to the front of the movable block 21 below each drill pipe cleaning nozzle 3. By setting two layers of drill pipe brush holders 4, arc-shaped brushes 5, and drill pipe cleaning nozzles 3, the cleaning of oil drilling drill pipes can be more fully realized, improving the cleaning effect of oil drilling drill pipes. An arc-shaped brush 5 is fixed on the inner wall of the drill pipe brush holder 4. Bristles 51 are evenly arranged on the inner side wall of the arc-shaped brush 5. A battery pack 9 is fixed to the top of the base 1 on the rear side of the water pump 8. The booster pump 8 is electrically connected to the battery pack 9. A pusher 11 is fixed to the top of the base 1. Four wheels 12 are fixedly installed at the four corners of the bottom of the base 1. In use, the adjusting disc 23 can be manually rotated counterclockwise to rotate the double-headed screw 22. The rotation of the double-headed screw 22 can drive the two movable blocks 21 to move away from each other, causing the two sets of drill pipe brush holders 4 and the two sets of drill pipe cleaning nozzles 3 to move away from each other. At this time, the base 1 is pushed to move the position of the device, placing the oil drilling drill pipe to be cleaned between the two sets of drill pipe cleaning nozzles 3 and the two sets of drill pipe brush holders 4. Then, the double-headed screw 22 is manually rotated clockwise to drive the two movable blocks 21 to move closer together, thereby... The movable block 21 drives the two sets of drill rod cleaning nozzles 3 and the two sets of drill rod brush holders 4 to move closer together, so that the bristles 51 on the arc-shaped brush 5 can effectively contact the drill rod wall. At this time, the water inlet of the booster water pump 8 can be connected to the external water supply pipe and the booster water pump 8 can be driven to rotate. The rotation of the booster water pump 8 can squeeze the water and deliver it to the two vertical pipes 6 through the two connecting hoses 7. The high-pressure water entering the two vertical pipes 6 can enter the two drill rod cleaning nozzles 3 through the two water inlet branch pipes 32, and finally spray it out from the nozzle 31 onto the drill rod wall to perform high-pressure washing of the drill rod. At the same time, when the drill rod moves up, the personnel can use the drilling machine to control the rotation of the drill rod to further improve the friction effect between the drill rod wall and the bristles 51, and achieve the washing of the drill rod wall.

[0022] The arc-shaped brush 5 is locked and fixed to the drill rod brush holder 4 by the anti-loosening nut 42. The inner side wall of the drill rod brush holder 4 is provided with an installation groove 41. The arc-shaped brush 5 is installed in the installation groove 41. A stud 52 is fixedly installed in the middle of the outer side wall of the arc-shaped brush 5. One end of the stud 52 passes through the through hole opened on the drill rod brush holder 4 and is threadedly engaged with the anti-loosening nut 42. By unscrewing the anti-loosening nut 42 from the stud 52, the arc-shaped brush 5 can be removed from the drill rod brush holder 4 for individual replacement, which is more effective. After a period of time, when the bristles 51 are severely worn and need to be replaced, the anti-loosening nut 42 can be rotated from the stud 52, and then the arc-shaped brush 5 can be taken out from the installation groove 41. The arc-shaped brush 5 can then be removed from the drill rod brush holder 4. Then, a new arc-shaped brush 5 is installed in the installation groove 41, and the anti-loosening nut 42 is screwed onto the stud 52, which completes the quick replacement of the arc-shaped brush 5.

[0023] Working Principle: During use, the adjusting disc 23 can be manually rotated counterclockwise to rotate the double-headed screw 22. The rotation of the double-headed screw 22 causes the two movable blocks 21 to move away from each other, thus distancing the two sets of drill pipe brush holders 4 and the two sets of drill pipe cleaning nozzles 3. At this time, the base 1 is pushed to move the device position, placing the oil drilling pipe to be cleaned between the two sets of drill pipe cleaning nozzles 3 and the two sets of drill pipe brush holders 4. Then, the double-headed screw 22 is manually rotated clockwise to move the two movable blocks 21 closer together. This, in turn, causes the two sets of drill pipe cleaning nozzles 3 and the two sets of drill pipe brush holders 4 to move closer together, ensuring effective contact between the bristles 51 on the arc-shaped brush 5 and the drill pipe wall. At this point, the inlet of the booster pump 8 can be connected to an external water supply pipe, driving the booster pump 8 to rotate. The rotation of the booster pump 8 squeezes and distributes the water. The high-pressure water is delivered to the two vertical pipes 6 through the two connecting hoses 7. The high-pressure water entering the two vertical pipes 6 can enter the two drill rod cleaning nozzles 3 through the two water inlet branch pipes 32 respectively, and finally spray out from the nozzles 31 onto the drill rod wall to perform high-pressure flushing of the drill rod. At the same time, when the drill rod is moved upward, the personnel can use the drilling machine to control the rotation of the drill rod to further improve the friction effect between the drill rod wall and the bristles 51, thereby achieving the cleaning of the drill rod wall. After a period of time, when the bristles 51 are severely worn and need to be replaced, the anti-loosening nut 42 can be screwed off the stud 52, and then the arc-shaped brush 5 can be taken out from the mounting groove 41. The arc-shaped brush 5 can then be removed from the drill rod brush holder 4. Then, the new arc-shaped brush 5 is installed in the mounting groove 41, and the anti-loosening nut 42 is screwed onto the stud 52 to complete the quick replacement of the arc-shaped brush 5.
