[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The moving motor 103 drives the threaded rod 105, thereby driving the rust removal rod 107 to move back and forth. During the movement, the guide rod 106 provides guidance to ensure the precise movement of the rust removal rod 107. The rust removal steel brushes 108 can clean and remove rust from the inner wall of the composite pipe during the movement. The back-and-forth movement and cleaning improves the rust removal effect.

[0031] The clamping assembly 2 has an upper clamping block 215 mounted on its top. An electric telescopic rod 216 is connected to the side of the upper clamping block 215. A lower clamping block 213 is connected to the bottom of the electric telescopic rod 216. A pneumatic lifting rod 212 is mounted on the bottom of the lower clamping block 213. A rotating shaft 210 is mounted on the bottom of the pneumatic lifting rod 212. A rotary motor 208 is mounted on the bottom of the rotating shaft 210.

A rotating support 209 is provided on the inner side of the rotating track 207. The upper clamping block 215, in conjunction with the electric telescopic rod 216, connects the upper and lower clamping blocks 213. The lower clamping block 213 and the upper clamping block 215 can be combined by adjusting the extension and retraction of the electric telescopic rod 216 to clamp the composite pipe. The fixed support facilitates rust removal after the composite pipe is fixed. The bottom of the lower clamp 213 is equipped with a pneumatic lifting rod 212, which can adjust the lifting height.

[0032] like Figure 7 As shown, an acid and alkali solution tank 301 is installed at the bottom of the chemical rust removal mechanism 3. A delivery pump 302 is installed on one side of the acid and alkali solution tank 301. A right-angle pipe 303 is connected to the bottom of the delivery pump 302. One end of the right-angle pipe 303 is fixedly connected to the side of the acid and alkali solution tank 301. The acid and alkali solution tank 301 can be loaded with acid and alkali solution. The right-angle pipe 303 can be connected to the delivery pump 302 to extract the acid and alkali solution inside the acid and alkali solution tank 301, providing chemical rust removal function for subsequent rust removal work. This facilitates the delivery and spraying of acid and alkali solution onto the inner wall of the composite pipe before cleaning and rust removal, loosening the rust in advance, thereby improving the efficiency of rust removal and ensuring the effect of rust removal.

[0033] like Figure 7 As shown, one end of the delivery pump 302 is connected to an output pipe 304, and one end of the output pipe 304 is connected to a hose 305.

[0034] like Figure 7As shown, multiple spray heads 306 are evenly distributed on the outer side of the rust removal rod 107, and multiple high-pressure nozzles 307 are evenly distributed on the outer side of the spray heads 306. The distribution of the spray heads 306 on the outer side of the rust removal rod 107 makes it easier to place them on the inner side of the composite pipe while cleaning. The high-pressure spraying of the high-pressure nozzles 307 achieves the rust removal work on the inner wall of the composite pipe, which helps to improve the rust removal effect through multiple treatment methods.

[0035] like Figure 3 As shown, a side bracket 101 is installed at the bottom of the rust removal component 1, and a support ring 102 is fixedly installed on one side of the top of the side bracket 101. The support ring 102 is sleeved on the outside of the moving motor 103. The side bracket 101 can work with the support ring 102 to provide stable support for the moving motor 103, thereby ensuring stability during the cleaning process.

One end of the translation screw 204 passes through one end of the translation rail 201 and is connected to the translation motor 202. The translation rail 201 can provide guidance. With the help of the translation motor 202, the translation screw 204 is driven to rotate, thereby realizing the translation operation of the translation slider 205. The groove 203 is located on the top inner side of the translation rail 201, which helps to improve the precise guiding effect of the translation, thereby realizing the translation operation of the clamping component, and further driving the composite tube to realize the translation operation.

[0038] like Figure 5 and Figure 6 As shown, a translation slider 205 is movably mounted on the top of the translation track 201. The inner side of the translation slider 205 is threadedly connected to the outer wall of the translation screw 204. The top of the translation slider 205 is connected to the bottom of the circular tray 206. The translation slider 205 can provide support for the circular tray 206 and also provide a transmission function, which is conducive to realizing the movement operation of the clamped parts. The translation screw 204 can drive the translation slider 205 to achieve effective movement through a threaded connection.

[0039] like Figure 5 and Figure 6As shown, a pneumatic pump 211 is installed at the bottom of the pneumatic lifting rod 212, and a driven roller 214 is movably installed on the inner side of the bottom of the lower clamping block 213. The lifting and lowering adjustment function of the pneumatic lifting rod 212 can be controlled by the pneumatic pump 211, and the driven roller 214 provides an auxiliary movement function when the composite pipe is transported and moved, thus improving the convenience of moving the composite pipe.

[0040] like Figure 5 and Figure 6 As shown, an active roller 217 is movably installed on the inner side of the upper clamping block 215. A drive motor 218 is installed at one end of the active roller 217, and one end of the drive motor 218 is connected to the outer side of the upper clamping block 215. The active roller 217 can cooperate with the drive motor 218 to drive the composite pipe to achieve effective displacement adjustment, which improves the convenience of rust removal work.

[0041] In this invention, the rust removal mechanism for the inner wall of the composite pipe is used by first driving the threaded rod 105 via the moving motor 103, which in turn drives the rust removal rod 107 to move back and forth. During the movement, the guide rod 106 provides guidance, ensuring the precise movement of the rust removal rod 107. The rust removal brush 108 cleans and removes rust from the inner wall of the composite pipe during the movement. The back-and-forth movement improves the rust removal effect. The side bracket 101, in conjunction with the support ring 102, provides stable support for the moving motor 103, thus ensuring stability during the cleaning process. The fitting ring 104 provides fitting support for the threaded rod 105, further enhancing the support stability. The translation track 2... 01 provides guidance, cooperating with the translation motor 202 to drive the translation screw 204 to rotate, thereby realizing the translation operation of the translation slider 205. The slide groove 203 is opened on the top inner side of the translation track 201, which helps to improve the precise guidance of the translation, thereby realizing the translation of the clamping parts, and further driving the composite tube to realize the translation operation. The translation slider 205 can provide support for the circular tray 206 and also provide a transmission function, which is conducive to realizing the movement operation of the clamped parts. The translation screw 204 can drive the translation slider 205 to achieve effective movement through a threaded connection. The upper clamping block 215 cooperates with the electric telescopic rod 216 to connect the upper and lower clamping blocks 213, and can then be moved by electric telescopic rod. The telescopic adjustment of rod 216 allows the lower clamping block 213 and upper clamping block 215 to merge, clamping and fixing the composite pipe. This facilitates rust removal after the composite pipe is fixed. Furthermore, the bottom of the lower clamping block 213 is equipped with a pneumatic lifting rod 212, which provides height adjustment. Rotation via the rotating shaft 210 and the rotary motor 208 allows for automatic reversal adjustment after cleaning one end of the composite pipe, especially when the pipe is long. This effectively improves the completeness of cleaning and rust removal, ensuring thorough rust removal. The rotary motor 208 is movably connected to the rotating track 207 on the top of the circular tray 206 via a rotating support 209, allowing the rotating support to... 209 provides lateral support during synchronous rotation in reversing direction, ensuring stability and facilitating stable use during rust removal. The pneumatic lifting rod 212 can be adjusted via the pneumatic pump 211. The driven roller 214 facilitates auxiliary movement during composite pipe transport, improving the ease of movement. The driving roller 217, in conjunction with the drive motor 218, effectively adjusts the displacement of the composite pipe, enhancing the convenience of rust removal. The acid / alkali solution tank 301 holds the acid / alkali solution, and the right-angle pipe 303, connected to the delivery pump 302, extracts the solution from the tank, providing chemical rust removal capabilities for subsequent processes.This allows for the application of acid and alkali solutions to the inner wall of the composite pipe before cleaning and rust removal, loosening the rust in advance and improving rust removal efficiency and effectiveness. The output pipe 304 connects to the hose 305, facilitating the connection between the delivery pump 302 and the rust removal section, enabling subsequent chemical pretreatment and improving the convenience of the rust removal process.
