Description

Technical Field

[0001] This utility model relates to the technical field of welding slag treatment devices, and in particular to the treatment of welding slag inside pipe fittings, specifically referring to a device for treating welding slag inside pipes. Background Technology

[0002] Welding slag remains inside pipes after welding. If this slag is not cleaned promptly, it can negatively impact the normal operation of the pipeline system. Currently, most traditional pipe slag removal equipment uses a rotating cleaning brush inserted into the pipe for cleaning. While this method can meet routine cleaning needs to some extent, it has significant drawbacks. Because the inner diameters of pipes used in different projects vary considerably, a cleaning brush of the appropriate size must be selected for each pipe diameter. Furthermore, if the selected brush size does not perfectly match the pipe's inner diameter, the cleaning effect will be poor. Therefore, developing a pipe slag removal device that can adapt to pipes of different diameters and eliminates the need for frequent replacement of cleaning components is of significant practical importance. Utility Model Content

A support platform 2 is connected to the left side of the upper end face of the base 1 via a lifting mechanism. The upper end face of the support platform 2 has a groove 3 for placing pipe fittings. A clamping assembly for clamping and fixing the pipe fittings is fixed at the upper end of the support platform 2. A movable seat 4 is slidably provided on the right side of the upper end face of the support platform 2. Two T-shaped slide rails 21 are fixedly provided on the right side of the upper end face of the base 1. The movable seat 4 is slidably provided on the two T-shaped slide rails 21. An electric push rod 5 for driving the movable seat 4 to move horizontally is fixedly provided on the upper end face of the support platform 2. A vertical plate 6 is fixedly provided on the upper end of the movable seat 4. A rotating shaft 7 is rotatably provided on the inner side of the vertical plate 6. A motor 13 for driving the rotating shaft 7 to rotate is fixedly provided on the outer side of the vertical plate 6. A plurality of spring telescopic mechanisms distributed circumferentially are fixedly provided at the end of the rotating shaft 7 near the pipe fitting. A wire brush 8 for cleaning welding slag is fixedly provided at the outer end of the spring telescopic mechanism.

[0028] In this embodiment, as a preferred technical solution, the spring telescopic mechanism includes a cavity 9 fixedly mounted on a rotating shaft 7, a rod 10 inserted into the cavity 9, a limiting plate 11 fixedly mounted at one end of the rod 10 extending into the cavity 9, a spring 12 sleeved on the rod 10 and located between the limiting plate 11 and the outer end of the cavity 9, and a wire brush 8 fixedly mounted at the outer end of the rod 10.

[0029] In this embodiment, as a preferred technical solution, the clamping assembly includes an arc-shaped bracket 14 fixedly disposed on the upper end of the support platform 2. The upper end of the arc-shaped bracket 14 is threadedly connected with a fastening bolt 15. The lower end of the fastening bolt 15 is rotatably provided with an arc-shaped pressure plate 16. The upper end of the arc-shaped pressure plate 16 is fixedly provided with a guide rod 17. The upper end of the guide rod 17 passes through the arc-shaped bracket 14 and is clearance-fitted with the arc-shaped bracket 14.

[0030] In this embodiment, as a preferred technical solution, the lifting mechanism includes an electric push rod 18 fixedly disposed on the upper surface of the base 1, a support platform 2 fixedly disposed on the upper end of the electric push rod 18, and a guide assembly connected between the four corners of the bottom of the support platform 2 and the base 1. The guide assembly includes a guide rod 19 fixedly disposed on the upper end of the base 1, and a cavity 20 fixedly disposed on the four corners of the bottom of the support platform 2. The guide rod 19 and the cavity 20 are inserted into each other.

[0031] The working principle of this pipe slag treatment device is as follows: The device uses a lifting mechanism to adjust the height of the support platform, making the central axis of the pipe fitting and the central axis of the rotating shaft coincide as much as possible. The pipe fitting is securely fixed by a clamping assembly to prevent displacement during cleaning. An electric push rod 5 drives the moving seat 4 to move horizontally, allowing the wire brush 8 to move axially along the pipe fitting. A motor 13 drives the rotating shaft 7 to rotate at high speed. Under centrifugal force, the wire brush 8 in the spring telescopic mechanism connected to the rotating shaft 7 overcomes the elastic force of the spring 12 and extends outward, automatically conforming to the inner wall of pipe fittings of different diameters to clean the welding slag inside the pipe.

[0032] The working process of the pipe slag treatment device of this utility model is as follows:

[0033] 1. Equipment Preparation: Start the electric push rod 18 and use the lifting mechanism to adjust the height of the support platform 2 on the base 1, so that the central axis of the pipe fitting and the central axis of the rotating shaft are as close as possible. During the lifting process, the guide rod 19 in the guide assembly slides smoothly within the cavity 20, ensuring that the support platform 2 is raised and lowered smoothly.

[0034] 2. Pipe Fitting Fixing: Place the pipe fitting with the welding slag to be cleaned into the groove 3 on the upper surface of the support platform 2, and fix the pipe fitting using the clamping assembly. Rotate the fastening bolt 15 on the arc-shaped bracket 14 to move the arc-shaped pressure plate 16 connected to the lower end of the fastening bolt 15 downward until the pipe fitting is firmly pressed. The guide rod 17 slides synchronously in the arc-shaped bracket 14 to ensure that the arc-shaped pressure plate 16 presses down vertically and firmly clamps the pipe fitting.

[0035] 3. Adjust the cleaning position: Start the electric push rod 5. The electric push rod 5 pushes the moving seat 4 to move horizontally on the T-shaped slide rail 21, so that the rotating shaft 7 and the wire brush 8 on the upright plate 6 move to the position of the welding slag inside the pipe fitting.

[0036] 4. Cleaning Weld Slag: Turn on motor 13, which drives shaft 7 to rotate at high speed. As shaft 7 rotates, centrifugal force acts on the spring extension mechanism. Under the influence of centrifugal force, the insertion rod 10 overcomes the elastic force of spring 12 and slides outward within cavity 9, causing the wire brush 8 to extend outward and automatically and tightly adhere to the inner wall of the pipe fitting. At the same time, the electric push rod 5 continues to operate, causing the high-speed rotating wire brush 8 to move axially along the pipe fitting, gradually completing the cleaning of weld slag inside the entire pipe fitting.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
