The movement of the U-shaped movable bracket 202 is restricted by the slide groove 205 and the slider 206 and can only move within a fixed range. At this time, the pipe 106 can be placed between the paired conveying rollers 203. Since the movable plate 208 compresses the return spring 211 when it moves, when the movable plate 208 is released, the device can be automatically reset under the action of the return spring 211, so that the conveying roller 203 clamps the pipe 106. At this time, the conveying motor 204 is used to drive the conveying roller 203 to rotate, which can achieve the effect of driving the pipe 106 to move.

[0041] In an optional embodiment: the cleaning mechanism 300 includes a positioning rod 301, a cleaning brush 302 is slidably installed on the positioning rod 301, the cleaning brush 302 is in contact with the pipe 106, and a positioning groove 312 is provided on the side of the positioning rod 301 close to the cleaning brush 302, a positioning slider 313 is slidably installed in the positioning groove 312, and the positioning slider 313 is fixedly installed on the cleaning brush 302.

[0042] It should be noted that the output end of the flip motor 308 drives the flip drive rod 309 to rotate, and the rotating flip drive rod 309 drives the flip drive slot 310 to slide in the flip drive slider 311 on the flip shaft 304, thereby achieving the effect of driving the flip shaft 304 to flip and jump on the fixed rod 303.

[0043] In an optional embodiment: a fixed rod 303 is installed on the inner wall of the workbench 101, a flip shaft 304 is rotatably installed on the fixed rod 303, two connecting grooves 306 are provided on the side of the flip shaft 304, a connecting slider 307 is slidably installed in the connecting groove 306, a connecting rod 305 is installed on the cleaning brush 302, and the connecting slider 307 is fixedly installed on the connecting rod 305.

[0044] It should be noted that the rotating flip shaft 304 cooperates with the connecting sliders 307 and the connecting grooves 306 at both ends to drive the two cleaning brushes 302 to continuously repeat the lifting process, thereby achieving the purpose of using the cleaning brushes 302 to clean the pipe wire 106.

[0045] In an optional embodiment: a flip motor 308 is installed on the inner wall of the workbench 101, a flip drive rod 309 is fixedly installed on the output end of the flip motor 308, a flip drive groove 310 is opened on the side of the flip shaft 304, a flip drive slider 311 is slidably installed in the flip drive groove 310, and the flip drive slider 311 is fixedly installed on the flip drive rod 309.

[0046] It should be noted that the rotating flip driving rod 309 drives the flip driving slot 310 to slide in the flip driving slider 311 on the flip shaft 304 , thereby driving the flip shaft 304 to flip and jump on the fixed rod 303 .

[0047] Working principle of this utility model:

[0048] When using the device, first, it is necessary to place the pipe 106 on the conveying mechanism 200, and use the movable handle 209 to push the movable plate 208 to the movable position. The movable movable plate 208 drives the transmission rod 207 to rotate through the transmission hole 212 and the transmission shaft 213. The rotating transmission rod 207 drives the U-shaped movable bracket 202 to the movable position on the mounting plate 201 through another pair of transmission holes 212 and the transmission shaft 213. The movement of the U-shaped movable bracket 202 is restricted by the slide groove 205 and the slider 206 and can only move within a fixed range. At this time, the pipe 106 can be placed between the pair of conveying rollers 203. Since the movable plate 208 compresses the return spring 211 when it moves, when the movable plate 208 is released, the device can be automatically reset under the action of the return spring 211, so that the conveying roller 203 clamps the pipe 106. At this time, the conveying motor 204 is used to drive the conveying roller 203 to rotate, thereby achieving the effect of driving the pipe 106 to move;

[0049] After the pipe 106 enters the workbench 101, it is firstly cleaned by the cleaning mechanism 300 to avoid excessive attachments on the pipe 106 before processing, which would generate unnecessary smoke. The thickness of the rusted material would also affect the processing time, which could reduce the consumption of electric energy. After processing, the melted slag on the surface of the pipe 106 can be removed. The flip motor 308 is started, and the output end of the flip motor 308 drives the flip driving rod 309 to rotate. The rotating flip driving rod 309 drives the flip driving groove 310 to slide in the flip driving slider 311 on the flip shaft 304, so as to achieve the effect of driving the flip shaft 304 to flip and jump on the fixed rod 303. The rotating flip shaft 304 drives the two cleaning brushes 302 to repeatedly rise and fall through the connecting sliders 307 and the connecting grooves 306 at both ends, so as to achieve the purpose of using the cleaning brushes 302 to clean the pipe 106. The movable cleaning brush 302 is restricted by the positioning groove 312 and the positioning slider 313 on the positioning rod 301 and can only move on the positioning rod 301.

[0050] In the laser rust removal mechanism 400, a sliding mounting seat 402 is arranged on the track of the annular track 401, and the displacement motor 407 is started to drive the rotating gear 408 to rotate. The rotating rotating gear 408 rotates on the annular gear ring track 409 to achieve the effect of driving itself and the sliding mounting seat 402 to move on the annular track 401. The sliding mounting seat 402 is restricted by the annular limiting groove 410 and the annular limiting slider 411 during the movement to ensure the stability of the movement. After the position is determined, the output end of the positioning hydraulic rod 406 is squeezed on the annular track 401 to achieve the positioning effect. The protective cover 405 provided on the sliding mounting seat 402 can prevent the laser beam from passing through the pipeline and affecting the equipment or staff. The three groups of laser rust removal mechanisms 400 can be irradiated at different positions of the pipeline, thereby ensuring that the pipeline is fully irradiated while moving, avoiding the occurrence of processing dead angles, and facilitating the adjustment of the angle to further ensure the processing range;

[0051] When the laser rust removal mechanism 400 is used to treat the pipeline, the rust material will burn and melt to produce smoke and debris. The fan 501 is used to absorb the smoke and transport it to the purification box 503, and the activated carbon filter material 507 is used to filter it, thereby reducing the impact of the smoke generated when the rust material melts on the environment, making the device more environmentally friendly.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
