[0029] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0030] 1. A linkage type directional circulation cleaning mechanism is set up. Through the mutual cooperation between the components inside the linkage type directional circulation cleaning mechanism, the processing process of the roller is optimized. The driving motor cooperates with the driving screw to drive the bottom circulation box and the components on it to move synchronously. The impurities generated by the roller during grinding, coating and laser repair are collected through the collection tray, and the impurities are collected through the circulating water inside the collection tray to prevent the impurities from sticking to the inner wall of the collection tray;

[0031] At the same time, through the mutual linkage between the driving rack, the driving inner wheel, the transmission outer wheel and the rotating circular wheel, and through the gear ratio between the driving inner wheel, the transmission outer wheel and the rotating circular wheel to accelerate the rotating circular wheel, the bottom circulation box can also drive the rotating circular wheel to rotate at high speed during the slow movement, and then the bottom circulation box can quickly replenish the circulating water inside the collection tray through the output circular paddle during the translation process, ensuring that the liquid level inside the collection tray can be continuously maintained within a suitable range, and through the alternating opening and closing of multiple isolation valves, different impurities at different repair stages can enter different filter bottom boxes for collection, thereby effectively improving the convenience of the repair equipment to handle impurities generated during the adsorption process, and at the same time, through the characteristics of the elastic rubber edge corners deforming inward after colliding with the roller support frame, the corners of the collection tray have a higher liquid difference during the discharge of the mixed liquid, so that the precipitated impurities gathered at the corners of the collection tray can smoothly flow into the corresponding isolation valve, thereby effectively improving the smoothness of impurity collection inside the collection tray;

[0032] At the same time, the overall weight of the repair equipment is adjusted through the water storage side box. During the transportation of the repair equipment, the circulating water inside it can be discharged to reduce the overall weight of the repair equipment, thereby making the transportation of the repair equipment more convenient. After the repair equipment is assembled at the construction site, the cooling water can be filled inside the water storage side box at the construction site. By adjusting the volume of the circulating water inside the bottom circulation box, the overall gravity of the bottom circulation box can be increased, so that the overall center of gravity of the repair equipment is lowered, and the transmission structure design between the driving rack and the driving inner wheel increases the motion damping of the bottom circulation box and its components, so that the bottom circulation box fits more closely with the driving long box and the driving screw during movement, thereby effectively improving the transportation stability of the repair equipment, and effectively improving the overall energy utilization efficiency during the operation of the repair equipment, solving the problems of inconvenience and unclean cleaning of large coarse and medium rollers, and being more automated and environmentally friendly.

[0033] 2. A flexible multi-angle adjustment mechanism is provided. Through the mutual adjustment between the components inside the flexible multi-angle adjustment mechanism, the overall adjustment process of the repair equipment is optimized. Through the mutual cooperation between the connector, the sealing valve and the water supply jacking pipe, the directional and quantitative filling of the buffer end groove at the end of the top driving beam is realized, and then the lateral position of the driving slider is adjusted by the circulating fluid in conjunction with the telescopic sleeve and the reset spring. The multi-angle adjustment of the swing end frame is realized by adjusting the mutual cooperation between the upper swing rod, the lower swing rod and the rotating connecting plate, and then the quick adjustment of the tilt angle and direction of the laser head is realized. At the same time, after the laser head is removed, other functional components can also be quickly replaced to the end of the swing end frame, making the operation of the repair equipment more convenient during the function adjustment process, further improving the convenience of use of the repair equipment;

[0034] The splicing structural design of the sealing bottom plate and the central protective net makes it easier to install the adsorption equipment during the splicing process. In the process of circulating water flowing inside the telescopic sleeve and the buffer end slot, a small amount of impurities in the circulating water can be intercepted and collected through the central protective net. After the repair equipment is used, the central protective net can be pulled out to quickly clean the inside of the repair equipment, effectively preventing impurities from entering the telescopic sleeve and damaging its inner wall, thereby effectively improving the overall service life of the repair equipment.

[0035] 3. An exhaust gas circulation treatment mechanism is set up. Through the mutual cooperation between the various components inside the exhaust gas circulation treatment mechanism, the exhaust gas treatment process of the repair equipment is optimized. The circulating fan, the collection front pipe and the collection box can quickly and conveniently extract and collect the flue gas generated during the laser alloying process, and the circulating water on the inner side of the installation back plate can be used to adsorb and collect dust particles in the flue gas, so that the dust can be directly precipitated into the installation slide frame in the circulating water, and the upper layer of the bottom circulation box can be cleaned by removing the installation slide frame after a single processing is completed, thereby effectively improving the environmental protection of the repair equipment during use;

[0036] After the entire repair process is completed and the circulating water inside the repair equipment is discharged, starting the circulating fan can continuously introduce external air into the small diversion box and the long heating box, and heat the continuously circulating air through the electric heating tube, and then dry the inner cavity of the bottom circulation box through the continuous circulation of hot air, and directionally guide the hot air flow when closing the flip sealing plate, so that the hot air flow can enter the top driving beam through the pipe to achieve the drying of the telescopic sleeve and the buffer end groove, thereby effectively preventing the residual liquid inside the repair equipment after use, and optimizing the convenience of overall drying of the repair equipment.

[0037] In summary, through the mutual cooperation between the linkage type directional circulation cleaning mechanism, the flexible multi-angle adjustment mechanism and the exhaust gas circulation treatment mechanism, the overall driving and use process of the repair equipment is optimized. Through the overall hollow splicing structure design of the equipment, the repair equipment is more convenient in the transportation process. After the repair equipment is spliced, the circulating water inside the water storage side box is introduced into the repair equipment through the front-end infusion pump, thereby realizing the adjustment of the overall weight of the repair equipment. The weight of the repair equipment is dynamically adjusted according to the different operation stages of the repair equipment, thereby ensuring the stable operation of the repair equipment while also collecting and treating the debris, waste and polluted flue gas generated in the adsorption process through the flow of circulating water, thereby optimizing the waste treatment process of the repair equipment and improving the environmental protection performance of the repair equipment. At the same time, the internal cavity of the repair equipment is dried by the continuous flow of hot air, which further improves the cleaning convenience and service life of the repair equipment. In addition, during the use of the repair equipment, the circulating fan and the front-end infusion pump at different processing stages can play a variety of different functions, simplifying the overall structure of the repair equipment and effectively expanding the function of the repair equipment.

[0074] After the entire repair process is completed and the circulating water inside the repair equipment is discharged, starting the circulating fan 501 can continuously introduce external air into the diversion box 505 and the heating long box 506, and heat the continuously circulating air through the electric heating tube 507, and then dry the inner cavity of the bottom circulation box 305 through the continuous circulation of hot air, and when the flip sealing plate 514 is closed, the hot air flow is directionally guided so that the hot air flow can enter the top driving beam 401 through the pipeline to achieve the drying of the telescopic sheath 410 and the buffer end groove 412, thereby effectively preventing the residual liquid inside the repair equipment after use, and optimizing the convenience of overall drying of the repair equipment.

[0075] Working principle and use process of the present invention: In the actual application process of the present invention, after determining the position of the roller to be processed, it is necessary to first transport the repair equipment to a suitable position, and then assemble the repair equipment around the roller to be processed, and then start to process the roller. In the process of successively grinding, cleaning and coating the outer side of the roller, the bottom plate 2 is installed to provide auxiliary support between the driving long box 301 and the components thereon, and at the same time, the components on the repair equipment are controlled by the central control console 1, and the driving motor 302 drives the driving screw 303 to rotate, and in the process of the driving screw 303 rotating, drives the driving mounting seat 304 to slide along the inside of the driving long box 301, and in the process of the driving long box 301 sliding, drives the bottom circulation box 305 and the components thereon to move synchronously;

[0076] During the movement of the bottom circulation box 305 along the top of the driving long box 301, the driving rack 310 and the driving inner wheel 311 cooperate with each other, so that the bottom circulation box 305 can drive the driving inner wheel 311 to rotate synchronously during the translation, and drive the transmission outer wheel 312 to rotate during the rotation of the driving inner wheel 311, and at the same time drive the rotating circular wheel 314 to rotate synchronously through the transmission outer wheel 312, and drive the output circular paddle 315 inside the conveying circular box 313 to rotate at a high speed during the rotation of the rotating circular wheel 314, and then transport the circulating liquid inside the conveying circular box 313 upward during the rotation of the output circular paddle 315, and enter the water supply hose 317 when the circulating liquid passes through the inside of the check bottom valve 316, so as to transport the circulating liquid upward through the water supply hose 317, and continuously supply liquid to the inside of the collection tray 318 from bottom to top through the water supply hose 317;

[0077] In the process of the collecting tray 318 moving along the bottom of the roller to be processed, the collecting tray 318 can collect the debris falling off the outer side of the roller, and the elastic rubber edge 319 can protect the edge of the collecting tray 318. After the collecting tray 318 collects the debris for a period of time, the bottom circulation box 305 will drive the collecting tray 318 and the elastic rubber edge 319 to move along the bottom of the roller to the edge of the roller support. When the elastic rubber edge 319 contacts the inner side of the roller support, it will elastically deform toward the inner side of the collecting tray 318, while buffering the side of the collecting tray 318 through the elastic The deformation of the rubber edge 319 pushes the transmission cross plate 329 and the center push plate 328 to stir the liquid inside the collection tray 318, so that the liquid inside the collection tray 318 can carry away the impurities precipitated at the corners during the disorderly flow, and after the elastic rubber edge 319 is separated and compounded with the roller support, the circulating water inside the collection tray 318 is reciprocally stirred through the elastic deformation of the elastic rubber edge 319 and the connecting rubber strip 327, so that the circulating water can continue to flow disorderly inside, so that the precipitated impurities gathered at the corners of the collection tray 318 can gather towards the center of the collection tray 318;

[0078] Then, the corresponding isolation valve 322 is opened to guide the circulating liquid inside the collection tray 318 together with the collected dirt in a directional manner, so that the mixed liquid enters the corresponding filter bottom box 324 through the reflux hose 323, and the solid impurities in the mixed liquid are intercepted and collected by the filter square box 325, and the filtered circulating liquid inside the filter bottom box 324 is guided back to the bottom circulation box 305 through the supporting bottom pipe 326 to realize the circulation of the circulating liquid. At the same time, the liquid required for use during the operation of the equipment can be stored through the water storage side box 306, and the liquid inside the water storage side box 306 can be transported through the front-end infusion pump 307, so that the circulating liquid inside the water storage side box 306 can enter the water replenishment bottom pipe 309 through the front-end water diversion valve 308, and the circulating liquid is added to the bottom circulation box 305 through the water replenishment bottom pipe 309 to replenish the circulating liquid inside the repair equipment;

[0079] When the position of each component on the top driving beam 401 needs to be adjusted, the circulating liquid is introduced into the water supply top pipe 416 through the front water diversion valve 308, and the circulating water in the water supply top pipe 416 can smoothly enter the buffer end tank 412, and when the circulating water flows through the buffer end tank 412, the impurities in the circulating water are centrally intercepted and collected through the central protection net 413 inside the buffer end tank 412, so as to improve the overall cleanliness of the circulating water;

[0080] Circulating water is continuously filled into the corresponding telescopic sheath 410 through the buffer end groove 412. As the amount of circulating water in the telescopic sheath 410 increases, the pressure inside the telescopic sheath 410 at the corresponding end increases and overcomes the elastic force of the return spring 411 to drive the driving slider 404 to slide along the top of the sealing bottom plate 402. The driving slider 404 is limited and guided by the guide groove 403 to prevent the driving slider 404 from deflecting during the sliding process. At the same time, during the sliding process of the driving slider 404, the components connected to the bottom thereof are synchronously driven to move synchronously, thereby realizing the adjustment of the lateral position of the laser head 409.

[0081] When the direction of the laser head 409 needs to be adjusted, the upper swing rod 405 and the lower swing rod 406 are adjusted to a suitable position by directional pulling, and the upper and lower sections of the upper swing rod 405 and the lower swing rod 406 are twisted relative to each other by rotating the connecting plate 407, so as to adjust the tilt angle and direction of the swing end frame 408, thereby adjusting the direction of the laser head 409;

[0082] In the process of alloying and repairing the roll, it is necessary to collect and process the smoke generated by the laser. A continuous airflow is generated inside the collection front pipe 502 through the circulation fan 501, and the inside of the collection small box 504 is continuously sucked through the cooperation between the connection box 503 and the pipeline. Then, the smoke generated during the laser alloying process is collected by the suction of the collection small box 504, and the waste gas is respectively introduced into the heating long box 506 through the diversion small box 505. Then, the waste gas is introduced into the heating long box 506 through the heating long box 506. Inside the guide side pipe 508, the exhaust gas can enter the inside of the installation back plate 509 through the guide side pipe 508, and the exhaust gas is washed by the circulating water on the upper layer of the bottom circulation box 305, and then the dust in the flue gas is adsorbed and collected by the circulating water, and the upper and lower layers of the bottom circulation box 305 are separated by the installation slide frame 510 and the collection fine mesh 511, and after a single processing is completed, the installation slide frame 510 is pulled out for cleaning, and the treated exhaust gas is introduced into the exhaust side box 513 through the exhaust side port 512;

[0083] After using the equipment, when it is necessary to clean the internal cavity of the equipment, first drain the internal circulating water, then start the electric heating tube 507 inside the heating long box 506, and use the electric heating tube 507 to quickly heat the natural air flow flowing through the heating long box 506. When the hot air flow flows through the bottom circulation box 305 and the top driving beam 401, the inside of the cavity can be quickly dried to prevent the liquid from remaining for a long time and causing damage to the inside of the equipment, thereby improving the convenience of cleaning the repair equipment.

[0084] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
