Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a rust removal device for the inner wall of a pipe. Background Technology

[0002] Given the environmental factors, particularly the effects of oxides, that affect steel pipes during storage, corrosion is a common occurrence. Typically, this corrosion falls under the category of chemical corrosion, a relatively slow process. However, over time, corrosion forms a thin, porous layer of brown rust on the pipe surface. Under the combined influence of air and moisture, this rust gradually leads to perforation on the pipe surface. Therefore, thorough rust removal before the steel pipes are put into use is crucial to prevent further corrosion. During machining, especially just before use, it is essential to ensure that the rust on the inner wall of the pipe is completely removed. Currently, most rust removal devices on the market are fixed designs, lacking the flexibility to effectively remove rust from pipes of varying lengths. Utility Model Content

At the same time, the inner clamping arm 134 can cooperate with the outer clamping arm 131 to securely clamp the pipe 5.

[0032] In this embodiment, the rust removal device 2 includes a support base 21. A movable slider 28 is provided at the bottom end of the support base 21. The movable slider 28 is sleeved on the lead screw 73 and slidably connected to the slide rail 72. In use, the slide rail drive motor 71 drives the lead screw 73 to rotate, thereby pushing the rust removal device 2 to slide within the slide rail 72. A power rod 25 is provided on the support base 21. One end of the power rod 25 has an external thread, and the other end has a stop block 27, which limits the extension and retraction position of the power rod 25. A helix is ​​provided in the middle of the power rod 25 for easy engagement with the gear 23. One end of the power rod 25 is threadedly connected to a rust removal mechanism 26, and the power rod 25 is connected to the power mechanism. Preferably, a power rod mounting bracket is provided on the support base 21. The power rod mounting bracket is installed on the support base 21 by fasteners. The power rod 25 passes through the power rod mounting bracket. The fasteners can be screws. When performing rust removal operations on pipes 5 of different lengths, the power rod mounting bracket and the power rod 25 can be replaced to flexibly adapt to pipes of various lengths.

[0033] In this embodiment, the power mechanism includes a rust-removing motor 24, a gear 23, and a driving worm gear 22. The rust-removing motor 24 is mounted on one side of the support base 21, and its output end is connected to the driving worm gear 22. The driving worm gear 22 passes through the support base 21 and meshes with the gear 23. The gear 23 is installed inside the support base 21 and meshes with the power rod 25. The rust-removing motor 24 drives the driving worm gear 22 to rotate, thereby driving the meshed gear 23 to rotate, which in turn drives the power rod 25 to extend and retract within the pipe.

[0034] In this embodiment, the rust removal mechanism 26 includes a threaded sleeve 261, which is threadedly connected to one end of the power rod 25. A rust removal ring is connected to the outer circumference of the threaded sleeve 261, and the rust removal ring is connected to the threaded sleeve 261 via a connecting rod 262. A steel wire brush 263 is wrapped around the rust removal ring. By providing the threaded sleeve 261, it is convenient to replace the brush of different sizes according to the pipe 5 of different sizes. Under the friction of the steel wire brush, the inner wall of the pipe 5 can be effectively derusted, improving the rust removal efficiency.

[0035] The beneficial effects of this embodiment are as follows: By incorporating a slide rail device, rollers, limit sliders, and moving sliders, the positions of the pipe support and rust removal device can be easily and quickly adjusted to meet the rust removal needs of pipes of various lengths, achieving convenient adjustment operations. The pipe rotation device allows the pipe to rotate, while the rust removal ring reciprocates against the inner wall of the pipe. The combined effect of rotation and reciprocating motion quickly cleans the inside of the pipe. The pipe can be installed and tightened according to its diameter by rotating the adjusting screw. The outer wall of the pipe abuts against the outer clamping arm, and the elastic element ensures close contact between the inner wall of the pipe and the inner clamping arm, resulting in a more uniform contact area and higher stability during rotation. Inner and outer protective pads on the inner and outer clamping arms prevent damage to the inner and outer walls of the pipe. A threaded sleeve on the rust removal ring, with an external thread at one end of the power rod, allows for easy assembly and disassembly of the rust removal ring, enabling repeated use. This design is easy to manufacture, low in cost, and convenient to use.

[0036] Example 2

[0037] The difference between this embodiment and Embodiment 1 is that this embodiment also includes a rust collection device 4, which includes a vacuum pump 41 and a collection pipe 42. The vacuum pump 41 is connected to the collection pipe 42. A through hole 141 is provided on the rotating shaft 14. The collection pipe 42 passes through the through hole 141 inside the rotating shaft 14 and extends into the pipe 5.

[0038] The working principle or operation process in this implementation is as follows: During use, the pipe 5 is placed inside the support cylinder 12. The pipe clamping assembly 13 and the pipe support assembly 3 work together to ensure that the pipe 5 remains horizontal. By adjusting the external adjusting screw 133, the external clamping arm 131 firmly fixes the pipe 5. The rotary motor 15 is started, driving the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the support cylinder 12 and the pipe clamping assembly 13 to rotate synchronously, thereby achieving synchronous rotation of the pipe 5, which is firmly clamped by the pipe clamping assembly 13. At the same time, the rust removal motor 24 is started, causing the active worm gear 22 to rotate, which in turn drives the power rod 25 to reciprocate, causing the rust removal mechanism 26 to reciprocate and clean the rust inside the pipe 5. Under the combined action of rotation and reciprocating motion, the rust inside the pipe 5 is quickly removed. At the same time, the vacuum pump 41 is started to quickly collect the rust debris cleaned from the inner wall of the pipe. When cleaning pipes of different lengths, first loosen the fasteners between the pipe support assembly 3 and the base 6, push the pipe support assembly 3 to adjust it to the preset position, and then fix the pipe support assembly 3 to the base 6 using the fasteners. Start the drive slide rail drive motor 71, slide the rust removal device 2 to the preset position, and the rust removal operation can begin.

[0039] The beneficial effect of this embodiment is that, by inserting a collection tube through the through hole and extending into the pipeline, rust debris can be collected in a timely manner during rust removal operations.

[0040] The advantages of this utility model are as follows: The installation of a slide rail device, rollers, limit sliders, and moving sliders allows for easy and quick adjustment of the pipe support components and rust removal device to meet the rust removal needs of pipes of various lengths, enabling convenient adjustment. The pipe rotation device allows the pipe to rotate, while the rust removal ring reciprocates against the inner wall of the pipe.
