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 traditional rust removal methods rely on the reciprocating motion of a rust brush to remove rust from the pipe's inner wall. However, this method is relatively inefficient and may leave some areas uncleaned, failing to meet the efficiency and quality requirements of modern industrial production. Utility Model Content

[0003] In view of the above-mentioned shortcomings of current rust removal devices, this utility model provides a pipe inner wall rust removal device, which can quickly clean the rust on the inner wall of the pipe under the synergistic action of the pipe rotation device and the rust removal device, thereby improving production efficiency and ensuring the cleanliness of the inner wall of the pipe.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pipe inner wall rust removal device includes a pipe rotating device 1 and a rust removal device 2. The pipe rotating device 1 includes a weighted base 11, on which a rotating shaft 15 passes. A support cylinder 12 is sleeved on the rotating shaft 15. The rotating shaft 15 is connected to a power drive device. A pipe clamping assembly 13 is arranged inside the support cylinder 12. One end of a pipe 5 is clamped by the pipe clamping assembly 13. The rust removal device 2 is arranged on the opposite side of the pipe clamping assembly 13. The rust removal device 2 includes a support base 21, on which a power rod 25 is arranged. A rust removal ring 26 is arranged at one end of the power rod 25. The power rod 25 is connected to a power mechanism. The power drive device drives the rotating shaft 15 to rotate, thereby driving the pipe 5 clamped by the pipe clamping assembly 13 to rotate. The power mechanism drives the rust removal ring 26 to reciprocate on the pipe 5. Under the friction of the steel wire brush of the rust removal ring 26, the inner wall of the pipe 5 can be effectively rusted, improving the rust removal efficiency.

[0028] In this embodiment, the rust-removing ring 26 can also be made of steel bars welded into a circle and directly connected to the power rod 25, with a wire brush on the outer ring of the steel bars; the rust-removing ring 26 can also include a threaded sleeve 261, with an external thread at one end of the power rod 25 and a stop block 27 at the other end, and a spiral line in the middle of the power rod 25 for easy engagement with the gear 23. The threaded sleeve 261 is threadedly connected to the power rod 25, and a connecting rod 262 is fixedly connected to the outer circumference of the threaded sleeve 261. A connecting ring is connected to the outside of the connecting rod, and a wire brush 263 is wrapped around the connecting ring. By setting 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 wire brush, the inner wall of the pipe 5 can be effectively derusted, improving the rust removal efficiency.

[0029] In this embodiment, a pipe support assembly 3 is also included. The pipe support assembly 3 is disposed at the other end of the pipe 5. The pipe support assembly 3 includes a pipe support base 31, on which a plurality of rollers 32 are disposed. The rollers 32 abut against the pipe 5, thereby fixing the pipe 5 in a relative position together with the pipe support assembly 3. Simultaneously, when the pipe 5 needs to rotate, the rollers 32 can rotate under the drive of an external force, thereby causing the pipe to rotate. Preferably, the top of the pipe support base 31 is V-shaped, and the rollers 32 are disposed on both sides of the V-shape.

[0030] In this embodiment, the pipe clamping assembly 13 includes an outer clamping arm 131, which is movably connected to the support cylinder 12. An inner clamping arm 134 is elastically connected to the outer wall of the rotating shaft 15. The outer clamping arm 131 and the inner clamping arm 134 are respectively clamped on the outer and inner walls of the pipe 5. Preferably, four outer clamping arms 131 and four inner clamping arms 134 are provided. The inner and outer clamping arms are arranged opposite to each other on the inner and outer walls of the pipe 5, and the pipe 5 is tightly clamped by the inner clamping arms 134.

[0031] In this embodiment, an external adjusting screw 133 is provided on the outer clamping arm 131, and the external adjusting screw 133 passes through the support cylinder 12. An elastic element 135 is connected to the inner clamping arm 134, and the elastic element 135 is connected to the rotating shaft 15. The elastic element 135 can be a helical compression spring, a disc spring, or other elastic element. An outer protective pad 132 is provided on the outer clamping arm 131, and the outer protective pad 132 is located on the outer wall side of the pipe 5. An inner protective pad 136 is provided on the inner clamping arm 134, and the inner protective pad 136 is located on the inner wall side of the pipe 5. The material of the inner and outer protective pads is not limited and can be silicone, rubber, or other materials, which can protect the inner and outer walls of the pipe 5 from damage while increasing the friction between the inner and outer clamping arms and the pipe 5. Adjusting the outer adjusting screw 133 can adjust the outer circumferential size of the outer clamping arm 131 so as to firmly clamp or remove the pipe 5. At the same time, the inner clamping arm 134 can cooperate with the outer clamping arm 131 to firmly clamp the pipe 5.

[0032] 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.

[0033] In this embodiment, the power drive device includes a pipe rotary motor 14 and a transmission component 16. The pipe rotary motor 14 is disposed at any position on one side of the weighted base 11. The pipe rotary motor 14 is connected to the rotating shaft 15 through the transmission component 16. The transmission component 16 is not limited and can be a belt, chain, or other transmission component. A stop 27 is provided at the other end of the power rod 25, which can limit the extension and retraction position of the power rod 25.

[0034] The beneficial effects of this embodiment are as follows: By setting up the pipe rotating device 1 and the rust removal device 2, the pipe rotating device 1 enables the pipe 5 to rotate, and the rust removal ring 26 reciprocates on the inner wall of the pipe. Under the synergistic effect of rotation and reciprocating motion, the interior of the pipe can be quickly cleaned. The pipe 5 can be installed and tightened according to its diameter by rotating the adjusting screw. The outer wall of the pipe 5 contacts the outer clamping arm 131, and the elastic element 135 ensures close contact between the inner wall of the pipe and the inner clamping arm 134, resulting in a more uniform contact area and higher stability during rotation. The inner and outer clamping arms are equipped with inner and outer protective pads to prevent damage to the inner and outer walls of the pipe. The rust removal ring 26 is equipped with a threaded sleeve 261, and one end of the power rod 25 has an external thread. The threaded sleeve is threaded onto the outer surface of the power rod 25, allowing for easy disassembly and reassembly of the rust removal ring 26 for repeated use. This design is easy to manufacture, low in cost, and convenient to use.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that it also includes a rust collection device 4. The rust collection device 4 includes a vacuum pump 41 and a collection pipe 42. The vacuum pump 41 can be set on one side of the pipe rotating device 1 or on the weighted base 11. The vacuum pump 41 is connected to the collection pipe 42. A through hole 151 is provided in the rotating shaft 15. The collection pipe 42 passes through the through hole 151 and extends into the pipe 5.

[0037] 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 inner clamping arm 134 works in conjunction with the pipe support assembly 3 to ensure the pipe 5 remains horizontal. By adjusting the outer adjusting screw 133, the outer clamping arm 131 is ensured to firmly fix the pipe 5. Next, the pipe rotation motor 14 is started, driving the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 causes the support cylinder 12 and the pipe clamping assembly 13 to rotate synchronously, thus achieving synchronous rotation of the pipe 5, which is firmly clamped by the pipe clamping assembly 13. Simultaneously, the rust removal motor 24 is started, causing the active worm gear 22 to rotate, thereby driving the power rod 25 to perform reciprocating motion 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, immediately sucking up the rust debris cleaned from the inner wall of the pipe.

[0038] The beneficial effect of this embodiment is that, by passing the collection pipe 42 through the through hole 151 and extending into the pipe 5, rust debris can be collected in a timely manner during rust removal operations.

[0039] The advantages of this utility model are as follows: The pipe rotation device and rust removal device enable the pipe to rotate, while the rust removal ring reciprocates within the pipe. The combined effect of rotation and reciprocating motion quickly cleans the inside of the pipe. The pipe can be installed and secured 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 for repeated use. This design is easy to manufacture, low in cost, and convenient to use. A collection pipe inserted into the through hole and extending into the pipe allows for timely collection of rust debris during rust removal operations. This utility model's pipe internal rust removal device can quickly clean rust from the inner wall of pipes, enabling repeated use, improving production efficiency, ensuring the cleanliness of the inner wall of pipes, and timely cleaning of rust debris inside the pipes.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
