Description

Technical Field

[0001] This utility model relates to the field of drilling pipes, and more particularly to a drilling pipe sand removal tool. Background Technology

[0002] Drill pipe cleaning tools are engineering equipment specifically designed to remove sand, gravel, and rock cuttings from the surface of drill pipes and inside the wellbore. They are mainly used to solve problems such as stuck drill pipe and wellbore instability caused by rock cuttings deposition during the drilling process.

[0003] Existing drilling pipe sand removal tools lack high-pressure flushing capabilities. Without this function, mechanical friction alone may not be sufficient to completely remove highly adhesive mud or small particles, leading to the formation of rock cuttings deposits on the inner or outer wall of the drill pipe. This can affect the flowability of drilling fluid and the pressure transmission efficiency of the drilling tools.

[0004] Therefore, given that existing drilling pipe sand removal tools lack high-pressure flushing capabilities and rely solely on mechanical friction to thoroughly remove highly adhesive mud or small particles, thus affecting subsequent drilling results, there is an urgent need to design a new type of drilling pipe sand removal tool. Utility Model Content

[0005] To overcome the problem that existing drilling pipe sand removal tools lack high-pressure flushing capabilities, relying solely on mechanical friction is insufficient to thoroughly remove highly adhesive mud or tiny particles, thus affecting subsequent drilling results.

[0006] The technical solution of this utility model is as follows: a drilling rod sand cleaning tool, including a movable frame; it also includes a motor, a screw, a slider, a water tank, a water pump, a water pipe, a diversion chamber, and nozzles. The motor is located on the right side of the front surface of the movable frame. The output end of the motor passes through the front surface of the movable frame and is connected to the screw. The rear surface of the screw is rotatably connected to the inner rear surface of the movable frame. The outer surface of the screw is threadedly connected to the slider. The upper surface of the slider is equipped with a water tank. The upper surface of the water tank is equipped with a water pump. One end of the water pipe is connected to the upper surface of the water pump. The other end of the water pipe is connected to the diversion chamber. Several nozzles are located on the left surface of the diversion chamber.

[0007] Preferably, by setting up a motor, the motor drives the screw to rotate when it runs. When the screw rotates, it restricts the rotation of the slider by a movable frame, thereby moving the slider. When the slider moves, it moves the water tank and its connecting parts together. Then, by starting the water pump, the water source in the water tank is pumped into the water pipe, and then the water pipe is transported to the distribution chamber. Finally, the distribution chamber distributes the water source to each nozzle and sprays it out under pressure, thereby achieving the purpose of high-pressure flushing. This solves the problem that existing drilling pipe sand cleaning tools lack high-pressure flushing function. Without high-pressure flushing function, it may be difficult to completely remove the highly adhesive mud or small particles by relying solely on mechanical friction, resulting in rock cuttings forming a sediment layer on the inner or outer wall of the drill pipe, affecting the fluidity of the subsequent drilling fluid and the pressure transmission efficiency of the drill string.

[0008] Preferably, a limiting rod is provided on the left side of the inner front surface of the movable frame one, and a slider two is slidably connected to the outer surface of the limiting rod. A connecting rod is installed on the left surface of the slider one, and the left surface of the connecting rod is connected to the right surface of the slider two. An installation plate is installed on the upper surface of the slider two, and an electric push rod is provided on the left surface of the installation plate. The telescopic end of the electric push rod passes through the left surface of the installation plate and is connected to a sponge brush.

[0009] Preferably, the upper surface of the movable frame one is provided with mounting brackets on both the front and rear sides, and a sliding rod is connected between the two mounting brackets. A fixed seat is provided on the rear side of the outer surface of the sliding rod, and a sliding seat is slidably connected to the outer surface of the sliding rod. The lower surfaces of the fixed seat and the sliding seat are both provided with movable frame two. A rotating handle is installed on the left surface of movable frame two. The right surface of the rotating handle passes through the left surface of movable frame two and is connected to a double-acting screw one. The right surface of the double-acting screw one is rotatably connected to the inner right surface of movable frame two. The outer surface of the double-acting screw one is threaded with two symmetrical clamping arms. The interior of each clamping arm is provided with a mounting groove, and several rollers are rotatably connected inside the mounting groove.

[0010] Preferably, a rocker arm is provided on the left surface of both handles, and a crank handle is rotatably connected to the lower side of the left surface of the rocker arm.

[0011] Preferably, the rear surface of the rear mounting bracket is provided with a mounting platform, the upper surface of the mounting platform is equipped with a motor two, the front surface of the motor two is provided with a movable frame three, the upper surface of the movable frame three is equipped with a motor three, the output end of the motor three passes through the upper surface of the movable frame three and is connected to a bidirectional lead screw two, the lower surface of the bidirectional lead screw two is rotatably connected to the inner lower surface of the movable frame three, and the outer surface of the bidirectional lead screw two is threaded with two symmetrical clamps.

[0012] Preferably, a dust storage bin is provided on the lower surface of the movable frame, and a drawer is slidably connected inside the dust storage bin.

[0013] Preferably, the dust storage bin has sliding grooves on both the left and right sides, and the drawer has slide rails on both the left and right sides, with the slide rails slidably connected to the sliding grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up motor one, the screw is driven to rotate by starting motor one. During the rotation of the screw, the rotational degree of freedom of slider one is constrained by the moving frame one, thereby pushing slider one to produce linear displacement. The translational movement of slider one synchronously pulls the water tank and its connecting parts to move as a whole. At this time, the water pump is activated to draw the liquid in the water tank into the water pipe. The water pipe delivers the liquid to the distribution chamber to complete the fluid distribution. Finally, the water flow is pressurized and sprayed through each nozzle to achieve the purpose of high-pressure flushing. This solves the problem that existing drilling pipe sand cleaning tools lack high-pressure flushing function. Without high-pressure flushing function, it may be difficult to completely remove the highly adhesive mud or small particles by relying solely on mechanical friction, resulting in rock cuttings forming a sediment layer on the inner or outer wall of the drill pipe, affecting the fluidity of the subsequent drilling fluid and the pressure transmission efficiency of the drill string.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a drilling pipe sand-removing tool, including a movable frame 1; it also includes a motor 2, a screw 3, a slider 4, a water tank 5, a water pump 6, a water pipe 7, a flow divider 8, and a nozzle 9. The motor 2 is located on the right side of the front surface of the movable frame 1. The output end of the motor 2 passes through the front surface of the movable frame 1 and is connected to the screw 3. The rear surface of the screw 3 is rotatably connected to the inner rear surface of the movable frame 1. The outer surface of the screw 3 is threadedly connected to the slider 4. The upper surface of the slider 4 is equipped with a water tank 5. The upper surface of the water tank 5 is mounted with a water pump 6. The upper surface of the water pump 6 is connected to... One end of the water pipe 7 is connected to a diversion chamber 8, and the other end of the water pipe 7 is connected to a diversion chamber 8. Several nozzles 9 are provided on the left surface of the diversion chamber 8. A motor 2 is provided, which drives the screw 3 to rotate when it runs. When the screw 3 rotates, the rotation of the slider 4 is restricted by the moving frame 1, thereby driving the slider 4 to move. When the slider 4 moves, it drives the water tank 5 and its connecting parts to move together. Then, the water pump 6 is started to pump the water source in the water tank 5 into the water pipe 7, and then the water pipe 7 delivers it to the diversion chamber 8. Finally, the diversion chamber 8 distributes the water source to each nozzle 9 and sprays it out under pressure, thereby achieving the purpose of high-pressure rinsing.

[0023] Please see Figures 1-3In this embodiment, a limiting rod 10 is provided on the left side of the inner front surface of the movable frame 1. A slider 2 11 is slidably connected to the outer surface of the limiting rod 10. A connecting rod 12 is installed on the left surface of slider 1 4. The left surface of the connecting rod 12 is connected to the right surface of slider 2 11. An mounting plate 13 is installed on the upper surface of slider 2 11. An electric push rod 14 is provided on the left surface of the mounting plate 13. The telescopic end of the electric push rod 14 passes through the left surface of the mounting plate 13 and is connected to a sponge brush 15. By setting slider 2 11, since slider 2 11 and slider 1 4 are connected by the connecting rod 12, slider 1 4 moves... When activated, the slider 11 moves, and an electric push rod 14 extends the sponge brush 15 to contact the drill rod surface, thus achieving friction cleaning. Mounting brackets 16 are provided on both the front and rear sides of the upper surface of the moving frame 11. A slide rod 17 connects the two mounting brackets 16. A fixed seat 18 is provided on the rear side of the outer surface of the slide rod 17. A sliding seat 19 is slidably connected to the outer surface of the slide rod 17. Moving frame 20 is provided on the lower surfaces of both the fixed seat 18 and the sliding seat 19. A rotating handle 21 is installed on the left surface of the moving frame 20. A bidirectional lead screw 22 is connected to the left surface of the movable frame 20 through the right surface. The right surface of the bidirectional lead screw 22 is rotatably connected to the inner right surface of the movable frame 20. Two symmetrical clamping arms 23 are threadedly connected to the outer surface of the bidirectional lead screw 22. Each clamping arm 23 has an installation groove 24 inside, and several rollers 25 are rotatably connected inside the installation groove 24. By setting a rotating handle 21, rotating the rotating handle 21 drives the bidirectional lead screw 22 to rotate. When the bidirectional lead screw 22 rotates, the rotation of the two clamping arms 23 is restricted by the movable frame 20, thereby driving the two clamping arms 23 to move forward. The relative movement of the two moving frames 20 is achieved by setting rollers 25 to rotate the clamped drill rod. Finally, by setting sliding seat 19, the distance between the two moving frames 20 can be adjusted to achieve the purpose of clamping drill rods of different lengths. The left surface of each of the two rotating handles 21 is provided with a rocker arm 26. The lower side of the left surface of the rocker arm 26 is rotatably connected to a crank handle 27. By setting the rocker arm 26, the torque applied to the rotating handle 21 by the operator can be increased. By setting the crank handle 27, the operator can have a gripping point when rotating the rocker arm 26, thereby achieving the purpose of rotating the rotating handle 21 in a labor-saving and comfortable manner.

[0024] Please see Figures 1-4In this embodiment, a mounting platform 28 is provided on the rear surface of the rear mounting bracket 16. A motor 29 is mounted on the upper surface of the mounting platform 28. A movable frame 30 is provided on the front surface of the motor 29. A motor 31 is mounted on the upper surface of the movable frame 30. The output end of the motor 31 passes through the upper surface of the movable frame 30 and is connected to a bidirectional lead screw 32. The lower surface of the bidirectional lead screw 32 is rotatably connected to the lower inner surface of the movable frame 30. Two symmetrical clamping plates 33 are threadedly connected to the outer surface of the bidirectional lead screw 32. By setting the motor 31, when the motor 31 runs, it drives the bidirectional lead screw 32 to rotate. When the bidirectional lead screw 32 rotates, the rotation of the two clamping plates 33 is restricted by the movable frame 30, thereby driving the two clamping plates 33 to move relative to each other. Motor 29 drives the moving frame 30 to rotate during operation, thereby achieving the purpose of automatically rotating the rotating rod. The lower surface of the moving frame 1 is provided with a dust storage bin 34, and a drawer 35 is slidably connected inside the dust storage bin 34. The dust storage bin 34 is used to collect the sand and dirt washed down. The drawer 35 can be pulled out to clean the sand and dirt accumulated inside. The left and right sides of the interior of the dust storage bin 34 are provided with sliding grooves 36, and the left and right sides of the drawer 35 are provided with slide rails 37. The slide rails 37 are slidably connected to the sliding grooves 36. The slide rails 37 move inside the sliding grooves 36 and are restricted by the sliding grooves 36. Since the slide rails 37 are connected to the drawer 35, the stability of the drawer 35 when it is pulled out is enhanced.

[0025] During operation, slider 21 is set up. Since slider 21 and slider 14 are connected by connecting rod 12, slider 21 moves when slider 14 moves. Electric push rod 14 extends sponge brush 15 to contact the drill rod surface, thus achieving friction cleaning. Rotating handle 21 drives double-acting screw 22 to rotate. When double-acting screw 22 rotates, it restricts the rotation of two clamping arms 23 through moving frame 20, thereby causing the two clamping arms 23 to move relative to each other. Roller 25 allows the clamped drill rod to rotate. Finally, sliding seat 19 allows the distance between the two moving frames 20 to be adjusted, thus allowing for clamping drill rods of different lengths. Rocker arm 26 increases the torque applied to rotating handle 21 by the operator. 27 provides a gripping point for the operator when rotating the rocker arm 26, thus achieving effortless and comfortable rotation of the handle 21. A motor 31 drives a double-acting screw 32 to rotate. The rotation of the double-acting screw 32 restricts the rotation of the two clamping plates 33 via a moving frame 30, causing the two clamping plates 33 to move relative to each other. A motor 29 then drives the moving frame 30 to rotate, achieving automatic rotation of the lever. A dust collection bin 34 is provided to store the washed-off sand and dirt. A drawer 35 can be pulled out to clean the accumulated sand and dirt. A slide rail 37 moves within a groove 36, its movement restricted by the groove 36. Since the slide rail 37 is connected to the drawer 35, the stability of the drawer 35 during operation is enhanced.

[0026] Through the above steps, by setting up motor 2, the screw 3 is driven to rotate by starting motor 2. During the operation of screw 3, the rotational freedom of slider 4 is constrained by moving frame 1, thereby pushing slider 4 to produce linear displacement. The translational movement of slider 4 synchronously pulls water tank 5 and its connecting parts to move as a whole. At this time, water pump 6 is activated to draw the liquid in water tank 5 to water pipe 7. Water pipe 7 delivers the liquid to distribution chamber 8 to complete fluid distribution. Finally, water flow is pressurized and sprayed through each nozzle 9 to achieve the purpose of high-pressure flushing. This solves the problem that existing drilling pipe sand cleaning tools lack high-pressure flushing function. Without high-pressure flushing function, it may be difficult to completely remove highly adhesive mud or small particles by relying solely on mechanical friction, resulting in rock cuttings forming a sediment layer on the inner or outer wall of the drill pipe, affecting the fluidity of subsequent drilling fluid and the pressure transmission efficiency of the drilling tool.
