Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a pipe inner wall rust removal machine. 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 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, existing pipe rust removal machines with power drives can only clean the inner wall of one pipe at a time, resulting in energy waste. Utility Model Content

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pipe inner wall rust removal machine includes a pipe rotating device 1 and a rust removal device 2. The pipe rotating device 1 clamps one end of a pipe 5 and drives the pipe 5 to rotate. The rust removal device 2 reciprocates within the pipe 5. At least two pipe rotating devices 1 are included, with rust removal devices 2 corresponding to each other on opposite sides of the pipe rotating devices 1. A rotating power device 6 is provided on one side of each pipe rotating device 1. One of the pipe rotating devices 1 is connected to the rotating power device 6 via a transmission component 8. The pipe rotating devices 1 are connected to each other via the transmission component 8. The rotating power device 6 drives each pipe rotating device 1 to rotate synchronously, thereby rotating the pipe 5. A rust removal power device 7 is provided on one side of each rust removal device 2. One of the rust removal devices 2 is connected to the rust removal power device 7 via the transmission component 8. The rust removal devices 2 are connected to each other via the transmission component 8. The rust removal power device 7 drives each rust removal device to reciprocate within the pipe 5. The rotary power device 6 and the rust removal power device 7 are not specifically limited and can be electric motors, fuel engines, etc. The transmission component 8 can be belts, chains, etc.

[0028] In this embodiment, the pipe rotating device 1 includes a weighted base 11 and a rotating shaft 14. The rotating shaft 14 passes through the weighted base 11, and a support cylinder 12 is sleeved on the rotating shaft 14. A pipe clamping assembly 13 is disposed inside the support cylinder 12. The pipe clamping assembly 13 firmly clamps the pipe 5. The rotating shaft 14 is connected to the rotating power device 6 through a transmission component 8. The pipe clamping assembly 13 includes an outer clamping arm 131 and an inner clamping arm 134. An outer adjusting screw 133 is disposed on the outer clamping arm 131 and passes through the support cylinder 12. An elastic element 135 is connected to the inner clamping arm 134 and is connected to the rotating shaft 14. The elastic element 135 can be a helical compression spring, a disc spring, etc. The outer clamping arm 131 and the inner clamping arm 134 clamp the outer wall and inner wall of the pipe 5, respectively. Preferably, four outer clamping arms 131 and four inner clamping arms 134 are provided. The inner and outer clamping arms are positioned opposite 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. An outer protective pad 132 is provided on the outer wall side of the pipe 5. An inner protective pad 136 is provided 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, etc., 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 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.

[0029] In this embodiment, a rust collection device 4 is also included. Preferably, the pipe rotating device 1 and the rust collection device 4 are arranged in a one-to-one correspondence. The rust collection device 4 includes a vacuum pump 41 and a collection pipe 42. The vacuum pump 41 can be arranged 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 141 is provided in 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.

[0030] In this embodiment, the rust removal device 2 includes a support base 21, on which a power rod 25 is mounted. 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 a 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 a transmission mechanism. The transmission mechanism is connected to the rust removal power device 7 through a transmission component 8.

[0031] In this embodiment, the transmission mechanism includes a gear 23 and a driving worm gear 22. The driving worm gear 22 is meshed with the gear 23, and the gear 23 is meshed with the power rod 25. The driving worm gear 22 is connected to the transmission component 8. The rust removal power device 7 drives the driving worm gear 22 to rotate, thereby driving the gear 23 meshed with it to rotate, which in turn drives the power rod 25 to extend and retract within the pipe.

[0032] 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.

[0033] The beneficial effects of this embodiment are as follows: By connecting the rotating power device 6 to one of the pipe rotating devices 1 via a transmission component 8, and connecting the pipe rotating devices 1 to each other via the transmission component 8, a single power device drives the synchronous rotation of multiple pipe rotating devices 1. Similarly, by connecting the rust-removing power device 7 to one of the rust-removing devices 2 via a transmission component 8, and connecting the rust-removing devices 2 to each other via the transmission component 8, a single rust-removing power device 7 drives multiple rust-removing devices to perform synchronous rust-removing operations. This allows for simultaneous rust removal of multiple pipes, saving energy and significantly improving production efficiency. Through the arrangement of the pipe rotating device 1 and the rust-removing device 2, the pipe rotating device 1 enables the pipe 5 to rotate, and the rust-removing mechanism 26 reciprocates within the pipe. The synergistic effect of rotation and reciprocating motion quickly cleans the interior of the pipe. The pipe 5 can be installed and secured 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. A threaded sleeve 261 is provided on the rust removal mechanism 26, 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 mechanism 26 for repeated use. This design is easy to manufacture, low in cost, and convenient to use. A collection pipe 42 passes through the through hole 141 and extends into the pipe 5, allowing for timely collection of rust debris during rust removal operations.

[0034] Example 2

[0035] The difference between this embodiment and embodiment one is that this embodiment also includes a pipe support component 3, which is disposed at the other end of the pipe 5, and the pipe support component 3 is disposed in a one-to-one correspondence with the pipe rotating device 1.

[0036] In this embodiment, 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 rollers 32 are disposed on both sides of the V-shape.

[0037] The working principle or operation process in this implementation is as follows: During use, pipes 5 are installed inside each support cylinder 12. The inner clamping arm 134 and the corresponding pipe support assembly 3 work together to ensure that pipes 5 remain horizontal. By adjusting the outer adjusting screw 133, the outer clamping arm 131 can firmly fix the pipes 5. After the pipes 5 are installed on each pipe rotating device 1, the rotating power device 6 is started to drive each rotating shaft 14 to rotate synchronously. The rotation of the rotating shaft 14 drives the support cylinder 12 and the pipe clamping assembly 13 to rotate synchronously together, thereby realizing the synchronous rotation of the pipes 5 firmly clamped by the pipe clamping assembly 13, thus realizing the synchronous rotation of multiple pipes 5. At the same time, the rust removal power device 7 is started to rotate the active worm gear 22, thereby driving the power rod 25 to reciprocate inside the pipes 5. Under the synergistic effect of rotation and reciprocating motion, the rust inside the pipes 5 is quickly removed, realizing the synchronous rust removal of multiple pipes. At the same time, the vacuum pump 41 is started to quickly suck up the rust debris cleaned from the inner wall of each pipe.

[0038] The beneficial effect of this embodiment is that by setting the pipe support component 3, one end of the pipe 5 that is far away from the pipe rotation device 1 can be effectively supported, thereby preventing the other end of the pipe 5 from shaking excessively during rotation and avoiding damage to the pipe during the rust removal process.

[0039] The advantages of this utility model are as follows: A single rotating power device drives multiple rotating pipe devices 1 to rotate synchronously via a transmission component. Similarly, a single rust-removing power device drives multiple rust-removing devices to perform synchronous rust removal operations via a transmission component. This allows multiple pipes to be rust-removed simultaneously, saving energy and significantly improving production efficiency. Through the arrangement of the rotating pipe device and the rust-removing device, the rotating pipe device 1 enables the pipe to rotate, and the rust-removing ring reciprocates on 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 secured according to its diameter by rotating the adjusting screw. The outer wall of the pipe contacts the outer clamping arm, and the elastic element ensures a tight 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. 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. A threaded sleeve is provided on the rust-removing ring, and one end of the power rod has an external thread. The threaded sleeve is threaded onto the outer surface of the power rod, allowing for easy disassembly and reassembly of the rust-removing ring for repeated use. This design is easy to manufacture, low in cost, and convenient to use. A collection pipe passes through the through hole and extends into the pipe, allowing for timely collection of rust debris during rust removal. A pipe support assembly effectively supports the end of the pipe furthest from the rotating device, preventing excessive shaking of the other end during rotation and avoiding damage to the pipe during rust removal. This utility model provides a pipe inner wall rust removal machine that uses a single rotating power unit to drive multiple pipe rotating devices and a single rust removal power unit to drive multiple rust removal devices, enabling simultaneous cleaning of rust from the inner walls of multiple pipes, saving energy and improving production efficiency.

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.
