Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically a ball-passing cleaning device for the inner wall of a bent pipe. Background Technology

[0002] In industrial production, bends are widely used in petroleum, chemical, and food processing industries. During the manufacturing or use of bends, burrs easily form on the inner wall, affecting the flow efficiency of the medium and the quality of the product. Traditional cleaning methods usually involve manual grinding or chemical cleaning, which are inefficient and costly. Therefore, there is an urgent need for a highly efficient and automated cleaning device to solve these problems.

[0003] A search revealed Chinese patent publication number CN206305139U, which discloses a pipe cleaning device. This device includes: a drive shaft; a rotating mechanism connected to the drive shaft; and a cleaning brush mounted on the drive shaft. The pipe cleaning device provided by this invention uses the rotating mechanism to drive the cleaning brush to remove iron slag adhering to the pipe wall, thoroughly removing the slag while saving time and effort.

[0004] However, the device lacks a dedicated clamping mechanism. The cleaning brush is only fixed by the drive shaft and the rotating mechanism, which cannot stably clamp the pipe. During the cleaning process, the pipe may be displaced due to the vibration of the rotating mechanism or external interference, resulting in unstable cleaning effect. Furthermore, the lack of a gripper or similar structure makes it unsuitable for pipes of different diameters, requiring additional pipe fixing during cleaning, which increases operational complexity and manual intervention. The device also lacks a pressure rod or similar structure, so the cleaning force of the cleaning brush depends entirely on the rotation speed of the rotating mechanism and the hardness of the bristles. It cannot flexibly adjust the pressure according to cleaning needs. For stubborn slag or thick impurities, the cleaning brush may not be able to provide sufficient pressure, resulting in poor cleaning effect. Utility Model Content

[0022] Please see Figure 1-4This utility model provides a ball-cleaning device for burrs on the inner wall of a bent pipe, including a first mounting frame 1, a first gripper 5, a second gripper 9, and a push rod 20. The first mounting frame 1 has a first gripper 5 on one side and a second gripper 9 on the side below the first gripper 5. A push rod 20 is located on one side of the first mounting frame 1, above the first gripper 5. A first hydraulic cylinder 6 is located on one side of the first mounting frame 1. Mounting seats 7 are fixedly connected to the outer walls of both sides of the first hydraulic cylinder 6. The first hydraulic cylinder 6 is installed into the mounting seats 7 and fixed to the first mounting frame 1 by screws. A first hydraulic cylinder 6 has a first... The hydraulic rod 8 has one end fixedly connected to the clamping arm 3, and the clamping arm 3 has one end fixedly connected to the first gripper 5. The push rod 20 has an iron ball 23 below it. The first gripper 5 is used to clamp the opening of the bent pipe, and the second gripper 9 is used to clamp the tail of the bent pipe. The push rod 20 is used to push the cleaning iron ball 23 through the bent pipe to remove burrs from the inner wall. Driven by the first hydraulic cylinder 6, the first hydraulic rod 8 can extend and retract, thereby driving the clamping arm 3 and the first gripper 5 to move laterally to clamp the opening of the bent pipe. The push rod 20 pushes the iron ball 23 downward along the pipe to clean the burrs in the pipe.

[0023] Example 2

[0024] Please see Figure 1-4 In this embodiment, the lower end of the first mounting bracket 1 is fixedly connected to the base 4, and the upper outer wall of the base 4 is fixedly connected to the limiting plate 15. The limiting plate 15 is provided with a rack 14 and a gear 22. The gear 22 meshes with the rack 14. The outer wall of one side of the limiting plate 15 is fixedly connected to the second mounting bracket 13. The second mounting bracket 13 is provided with a rotating motor 12 on one side. The rotation center of the rotating motor 12 is fixedly connected to the rotation shaft of the gear 22. One side of the gear 22 is connected to the bearing 16, and one side of the bearing 16 is connected to the limiting plate 15. The upper outer wall of the rack 14 is fixedly connected to the fixing bracket 17. The rotating motor 12 drives the gear 22 to rotate, and the gear 22 meshes with the rack 14, driving the rack 14 to move up and down, thereby adjusting the height of the second gripper 9 so that the second gripper 9 can adapt to bent pipes of different sizes.

[0025] A second hydraulic cylinder 11 is fixedly connected to one side of the fixed frame 17. The second hydraulic cylinder 11 is equipped with a second hydraulic rod 10. A second gripper 9 is fixedly connected to one end of the second hydraulic rod 10. Driven by the second hydraulic cylinder 11, the second hydraulic rod 10 can extend and retract, thereby driving the second gripper 9 to perform clamping or releasing operations, thus realizing the clamping of the tail of the bent pipe.

[0026] The upper outer wall of the first mounting bracket 1 is provided with a third hydraulic cylinder 18, and the third hydraulic cylinder 18 is provided with a third hydraulic rod 19. The third hydraulic rod 19 is fixedly connected to the counterweight 21. Driven by the third hydraulic cylinder 18, the third hydraulic rod 19 can extend and retract, driving the counterweight 21 to move up and down, thereby realizing the pressure adjustment of the push rod 20.

[0027] The lower end of the counterweight 21 is provided with a push rod 20, which is fixed to the counterweight 21 by screws. By replacing the push rod 20 with different sizes, it can adapt to the bends of different diameters, ensuring that the cleaning iron ball 23 can pass through the bend smoothly and clean the burrs.

[0028] A support rod 2 is fixedly connected to one side of the first mounting frame 1. The support rod 2 is fixedly connected to the base 4. The support rod 2 is used to enhance the stability of the first mounting frame 1 and ensure that the device remains stable during operation.

[0029] It should be noted that, in this embodiment, when using this device, firstly, the dimensions of the bent pipe to be deburred are measured, the first hydraulic cylinder 6 is driven to extend and retract the first hydraulic rod 8, causing the clamping arm 3 and the first gripper 5 to move laterally and clamp the opening of the bent pipe. Next, the rotary motor 12 is driven to rotate the gear 22, causing the rack 14 to move upward, so that the center of the second gripper 9 reaches the horizontal diameter height of the end of the bent pipe. Then, the second hydraulic cylinder 11 is driven to extend and retract the second hydraulic rod 10, causing the second gripper 9 to clamp the end of the bent pipe, completing the double clamping of the bent pipe. According to the dimensions of the bent pipe, the push rod 20 of the corresponding size is replaced, and the push rod is... The push rod 20 is fixed to the bottom of the counterweight 21 with screws. In traditional devices, workers need to manually re-fix the counterweight 21 each time it is pressed down. Replacing and installing different pressure rods can maximize the maximum pressure that the pressure rod can withstand, which not only ensures the smooth completion of the cleaning work, but also ensures the safety of the workers. Driving the third hydraulic cylinder 18 causes the third hydraulic rod 19 to extend and retract, which drives the counterweight 21 and the push rod 20 to move, pushing the cleaning iron ball 23 out of the bend pipe, completing the cleaning of the burrs in the pipe. Finally, driving the first hydraulic cylinder 6 and the second hydraulic cylinder 11 releases the first clamp 5 and the second clamp 9, and the pipe is replaced for the next cleaning work.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
