[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention is equipped with a pipe cleaning module. After the weld of the stainless steel pipe cracks, before the repair welding, the cleanliness of the weld and its surrounding areas will affect the welding quality, and even cause the repair welding to fail or the weld to crack again. The combined use of the cleaning brush, the wiping soft cloth and the stripping shovel can carry out targeted cleaning for different types of impurities. The cleaning brush is used to remove larger impurities and particles, the wiping soft cloth is used to remove fine impurities and oil stains, and the stripping shovel can penetrate into the inner wall of the stainless steel pipe to remove stubborn attachments. This multi-level cleaning method ensures the thorough cleaning of the weld area, laying a solid foundation for high-quality welding. The present invention can effectively clean the stainless steel by combining the cleaning brush, the wiping soft cloth and the stripping shovel. Various impurities on the inner wall of the pipe ensure the cleanliness of the weld area, thereby improving the success rate of repair welding and the quality of the weld. Through the integrated pipe cleaning module, multiple cleaning steps can be completed at one time, which greatly improves the cleaning efficiency and the preparation speed before welding, and improves work efficiency. And through the Velcro design, the wiping soft cloth can be easily replaced, which means that the operator can choose a suitable wiping soft cloth for cleaning according to the material, degree of contamination and cleaning requirements of the stainless steel pipe. This flexibility enables the present application to be widely used in the cleaning of various stainless steel pipes, improves its adaptability and practicality, and therefore can solve the problems of insufficient cleanliness in the weld area, low welding preparation efficiency and high risk of repair welding failure.

[0034] 2. The present invention is equipped with an impurity collection component. During the cleaning process of the inner wall of the stainless steel pipe, a large amount of impurities will be generated by the scraping of the stripping shovel, the wiping of the wiping core and the cleaning of the sweeping core. If these impurities cannot be effectively collected and managed, they will not only pollute the working environment, but also cause welding defects or quality problems due to the residual impurities. The design of the impurity collection component allows these impurities to be collected in real time during the cleaning process to keep the repair welding work area clean. At the same time, the impurity collection component can seal the impurities in the collection tank during the cleaning process to prevent them from spreading or polluting again. Since the impurities can be collected in real time, there is no need to stop frequently during the cleaning process to clean or process the impurities, thereby improving the efficiency of the entire cleaning process, and the gravity plate and the limit plate The design makes the impurity collection process almost unnecessary for human intervention, and the automatic collection and sealing of impurities can be achieved only through the drive of the servo motor. When the servo motor drives the repair welding support body to rotate, it drives the wiping core to rotate. When the limit plate is above the gravity plate, the gravity plate is perpendicular to the ground under the influence of gravity, so that the collection slot is in an open state, and impurities can enter the collection slot at this time. When the limit plate is below the gravity plate, the limit plate is used to limit the activity range of the gravity plate, so that the collection slot is in a closed state, and the impurities inside the collection slot will not flow back out, which greatly reduces the operation complexity and labor cost. Therefore, it can solve the impurity collection in the cleaning process, improve the cleaning efficiency and the repair welding quality, and at the same time ensure the cleanliness of the repair welding environment and the convenience of operation.

[0035] 3. The present invention is equipped with a high-temperature alloy arc support plate, a high-temperature resistant rubber cushion layer, a silicone elastic cushion layer, a metal stress dispersion sheet, a temperature sensor and a pressure sensor. During the repair welding process, due to the effect of welding thermal stress and mechanical stress, the stainless steel pipe is easily deformed. The high-temperature alloy arc support plate provides stable support for the stainless steel pipe with its high strength and high temperature resistance. At the same time, the high-temperature resistant rubber cushion layer and the silicone elastic cushion layer serve as a buffer layer, which can absorb part of the welding stress and thermal stress, further reducing the risk of deformation of the stainless steel pipe. The uniform arrangement of the metal stress dispersion sheet helps to disperse the stress generated during the welding process and avoid weld cracking or quality problems caused by stress concentration. In addition, through real-time monitoring of the temperature sensor and the pressure sensor, the operator can accurately grasp the temperature and pressure changes during the welding process, so as to adjust the welding parameters in time and ensure the stability and consistency of the welding quality. The introduction of the micro electric push rod enables the repair welding support module to adjust the support strength and position as needed, realize the precise control of the stainless steel pipe, and can be fine-tuned according to the actual situation during the welding process to ensure the optimization of the welding effect. Therefore, the problems of pipe deformation, unstable welding quality and difficulty in accurately controlling welding conditions during the repair welding process can be solved.

[0036] 4. The present invention is equipped with a fixing sleeve, a fixing frame, a hydraulic rod, a fixing block 1, a fixing block 2, an anti-skid pad, a bottom bracket and a side bracket. The fixing sleeve sleeved on the outer surface of the repair welding support body and the fixing frame are designed to be detachable, so that after the repair welding work is completed, the operator can easily disassemble and clean the repair welding support module, the pipe cleaning module and the impurity collection component, which not only improves the maintainability of the repair welding support device, but also prolongs the service life of the repair welding support device. The fixing block 2 is used to fix the hydraulic rod and the fixing frame on one side thereof, and the fixing block 1 is used to fix the bottom bracket. The bottom bracket and the side bracket are connected by a hinge to facilitate the opening and closing of the side bracket. At the same time, through the bottom bracket, the anti-skid pad and two groups of symmetrically arranged side brackets The combination of the frame and the connecting plate forms an external stable support structure, which can effectively fix the stainless steel pipe to be repaired, ensuring that the stainless steel pipe can maintain a stable position and shape during the repair welding process, thereby avoiding the deformation problem caused by welding heat. Since the stainless steel pipe is firmly fixed, it is easier to control the welding position and angle during the repair welding, thereby improving the accuracy and efficiency of the repair welding, and the stable support also reduces the problem of unstable welding quality caused by the movement of the stainless steel pipe, and also reduces the potential safety risks caused by the instability of the stainless steel pipe. Therefore, it can solve the problem of pipe deformation during the repair welding process, improve the accuracy and efficiency of the repair welding, facilitate cleaning and maintenance, and enhance the safety of the repair welding work.

[0058] Furthermore, the fixed shaft 4 is firmly mounted on one end of the repair welding support body 3, providing a rotation and movement reference for the sweeping core 5, the wiping core 6 and the stripping shovel 7, ensuring effective cleaning operations. The stripping shovel 7 is located on the far left and first contacts the inner wall of the stainless steel pipe 2. The stripping shovel 7 is used to remove stubborn impurities and larger particles attached to the inner wall, laying a foundation for subsequent cleaning work and ensuring the initial achievement of the cleaning effect.

[0059] The wiping core 6 is located behind the stripping shovel 7, and its outer surface is evenly arranged with hook-surface Velcro 9, and the outer surface of the hook-surface Velcro 9 is adhered with a fleece-surface Velcro 10, and a wiping soft cloth 11 is installed on the fleece-surface Velcro 10. The wiping soft cloth 11 is made of a soft and absorbent material, which can fit tightly against the inner wall of the pipe and effectively absorb and wipe the residual impurity particles, including water and oil. Through the quick replacement design of the hook-surface Velcro 9 and the fleece-surface Velcro 10, the operator can easily replace the dirty wiping soft cloth 11 to maintain the continuity and efficiency of the cleaning work;

[0060] The sweeping core 5 is located behind the wiping core 6, and cleaning brushes 8 are evenly arranged on its outer surface. The bristles of the cleaning brushes 8 can penetrate into the tiny gaps in the inner wall of the stainless steel pipe 2, and further remove the fine impurities and residues that the stripping shovel 7 and the wiping soft cloth 11 have not been able to completely remove. By rotating and moving, the cleaning brush 8 can achieve a comprehensive cleaning of the inner wall of the pipe, thereby improving the cleanliness;

[0063] Furthermore, the collecting tank 12 is provided inside the wiping core 6, and is used to collect impurities and particulate matter removed from the inner wall of the stainless steel pipe 2 by the cleaning brush 8 and the wiping soft cloth 11, so that the impurities can be smoothly introduced and temporarily stored inside the collecting tank 12, and the connecting block 13 is installed on one side inner wall of the collecting tank 12, and serves as a connecting bridge between the gravity plate 14 and the collecting tank 12, and the connecting block 13 ensures that the gravity plate 14 can be stably installed in the collecting tank 12, and allows the gravity plate 14 to perform necessary activities;

[0074] Furthermore, the servo motor is used to drive the rotation of the repair welding support body 3 and the fixed shaft 4, and provide power for the sweeping core 5, the wiping core 6 and the stripping shovel 7. The protective shell should have good heat dissipation performance and protection level to ensure that the servo motor does not overheat during long-term operation and prevent dust and splashing from entering the motor to extend its service life. The fixed sleeve 21 is sleeved on the repair welding support body 3 to provide additional support and stability. It is recommended to be made of high-strength and corrosion-resistant materials to adapt to the welding environment. The fixing frame 22 is connected to the fixing sleeve 21 by threads.

The two sets of connecting plates are connected by bolts, so that the side bracket 27 can be fine-tuned according to the diameter of the stainless steel pipe 2 and its position is fixed by tightening the bolts.

[0079] See also Fig.10 The present invention provides an embodiment: a deformation-resistant stainless steel pipe weld crack repair welding support device, wherein the inner surfaces of the bottom bracket 26 and the side bracket 27 are installed with anti-slip pads 25, and the stainless steel pipe 2 is placed inside the anti-slip pads 25.

[0080] Furthermore, the anti-skid pad 25 is installed on the inner surface of the bottom bracket 26 and the side bracket 27, and is in direct contact with the stainless steel pipe 2, which significantly increases the friction between the stainless steel pipe 2 and the bottom bracket 26 and the side bracket 27, and effectively prevents the stainless steel pipe 2 from sliding or shifting during the welding process. The anti-skid pad 25 is made of soft and wear-resistant material, which not only has good anti-skid performance, but also forms a protective layer on the surface of the stainless steel pipe 2, reducing surface scratches or damage caused by direct contact with the bottom bracket 26 and the side bracket 27. With the support of the anti-skid pad 25, the stainless steel pipe 2 can maintain a more stable posture during the repair welding process. This helps to reduce the deformation of the pipe caused by welding thermal stress and improve the welding quality.

[0081] Further, the method of using the repair welding support device is as follows:

[0082] S1, fix the stainless steel pipe 2 that needs to be repaired by the stainless steel pipe fixing module;

[0083] S2, cleaning impurities inside the stainless steel pipe 2 by using the pipe cleaning module before repair welding;

[0084] S3, collecting impurities cleaned by the pipe cleaning module through an impurity collection component;

[0085] S4, supporting the stainless steel pipe 2 by means of a repair welding support module, and then performing repair welding.

[0086] Furthermore, in S2, the following steps are also included:

[0087] S21, driving the pipe cleaning module by the servo motor, first entering the stripping shovel 7 of the stainless steel pipe 2 to remove impurities on the inner wall of the stainless steel pipe 2;

[0088] S22, then wipe the impurity particles on the inner wall of the stainless steel pipe 2 with the soft cloth 11, and further clean the impurities on the inner wall of the stainless steel pipe 2 with the cleaning brush 8;

[0089] S23, displacement sensor and vibration sensor monitor the displacement and vibration during the repair welding process respectively.

[0090] Working principle: The stainless steel pipe 2 is placed on the bottom bracket 26, which is firmly mounted on the repair welding workbench 1 through a fixing block 23. The side bracket 27 is connected to the bottom bracket 26 through a hinge and is fine-tuned through a connecting plate and bolts to adapt to stainless steel pipes 2 of different sizes. The inner surfaces of the bottom bracket 26 and the side bracket 27 are installed with anti-skid pads 25 to increase the friction between the stainless steel pipe 2 and the side bracket 27 and the bottom bracket 26, so as to prevent the stainless steel pipe 2 from sliding or shifting during the repair welding process.

[0091] Before repair welding, the pipe cleaning module is driven by a servo motor, so that the fixed shaft 4 drives the sweeping core 5, the wiping core 6 and the stripping shovel 7 to enter the stainless steel pipe 2. The stripping shovel 7 first removes the large impurities on the inner wall of the stainless steel pipe 2, and then the wiping soft cloth 11 wipes the remaining impurity particles, and finally the cleaning brush 8 further cleans the fine impurities. During the whole cleaning process, the impurities are collected in the collection tank 12 inside the wiping core 6, and the gravity plate 14 and the limit plate 15 are used to ensure that the impurities will not overflow;

[0092] The repair welding support module is driven by a micro electric push rod 16 evenly installed on the outer surface of the repair welding support body 3. The micro electric push rod 16 pushes the high-temperature alloy arc support plate 17 to close to the outer wall of the stainless steel pipe 2. The high-temperature resistant rubber cushion layer 18, the silicone elastic cushion layer 19 and the metal stress dispersion sheet 20 inside the high-temperature alloy arc support plate 17 provide good support and buffering effects, effectively dispersing the thermal stress and mechanical stress during welding;

[0093] The temperature sensor and pressure sensor monitor the temperature and pressure during the repair welding process in real time to ensure the safety and stability of the repair welding process. The displacement sensor and vibration sensor embedded in the repair welding support body 3 respectively monitor the displacement and vibration during the repair welding process. The hydraulic rod is installed on the repair welding support body 3 through the fixing sleeve 21 and the fixing frame 22, which is used to further adjust the position of the repair welding support module. After completing the fixation and cleaning of the pipe, the repair welding support module starts and supports the stainless steel pipe 2. Then, the welding equipment starts to repair the weld. During the entire repair welding process, the repair welding support module and the pipe cleaning module work together to ensure the accuracy and stability of the repair welding. At the same time, the temperature sensor, pressure sensor, displacement sensor and vibration sensor monitor various parameters in the repair welding process in real time to provide real-time feedback to the operator.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
