Technical Field

[0001] This utility model relates to the field of manufacturing technology of metal products for fire protection, specifically an automatic pressure groove device for main pipes in fire protection engineering. Background Technology

[0002] In fire protection engineering, the main piping system is a core component of fire water supply. Metal pipes in the main piping system typically use grooved connections for rapid installation and sealing. When using this connection method, annular grooves need to be pressed into the pipe ends. A grooving machine is a commonly used pipe grooving device that directly cold-forms grooves through mechanical rolling. However, in related technologies, grooving machines generally lack automatic grooving quality detection capabilities, relying on post-processing inspection. This leads to a lack of timely intervention when errors occur in grooving, increasing the pipe scrap rate. Furthermore, the edges of the grooving rollers are prone to wear, and replacing integral grooving rollers requires replacing the entire unit, resulting in resource waste. Therefore, this application proposes an automatic grooving device for main pipes in fire protection engineering. Utility Model Content

[0003] This utility model provides an automatic pressure grooving device for main pipes in fire protection engineering, which solves the problems mentioned in the background art, such as the inability to intervene in time when pressure grooving errors occur, which increases the pipe scrap rate; and the need to replace the entire pressure grooving roller when replacing the integral structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an embodiment: Please refer to Figures 1-6 An automatic pressure trough device for fire protection main pipes includes a base 1. A support plate 2, which is inverted L-shaped, is provided on one side of the top of the base 1. A clamping structure 10 adapted to the fire protection main pipe is provided in the middle of the vertical part of the support plate 2. A servo motor 3 is provided on the outer side of the vertical part of the support plate 2. The output shaft of the servo motor 3 is connected to the clamping structure 10 through a reducer. When the servo motor 3 rotates, it can drive the clamping structure 10 to rotate. A shock-absorbing pad is provided between the servo motor 3 and the base 1 to reduce the impact of the vibration of the servo motor 3 on the structure on the base 1.

[0022] The clamping structure 10 includes a fixed plate 14. The output shaft of the servo motor 3 is connected to the fixed plate 14. A guide plate 16 is fixedly connected to the inner side of the fixed plate 14. A double-headed cylinder 17 is provided on the inner side of the guide plate 16. Guide grooves are distributed circumferentially on the guide plate 16. A connecting rod 15 is movably connected in the guide groove. One end of the connecting rod 15 near the fixed plate 14 is connected to the output shaft of the double-headed cylinder 17. Two connecting rods 15 connected to the two output shafts of the double-headed cylinder 17 are arranged opposite to each other on the guide plate 16. The other end of the connecting rod 15 is fixedly connected to an inner support block 13 that is adapted to the inner diameter of the fire protection engineering main pipe. Under the action of the double-headed cylinder 17, the distance between the two symmetrically arranged inner support blocks 13 can be changed. The inner support blocks 13 can fit tightly against the inner wall of the fire protection engineering main pipe. The clamping structure 10 realizes the fixation of the fire protection engineering main pipe. Under the action of the double-headed cylinder 17, the inner support blocks 13 can be separated from the inner wall of the fire protection engineering main pipe, which facilitates the disassembly and assembly of the fire protection engineering main pipe. The outer diameter of the guide plate 16 is larger than the inner diameter of the fire protection main pipe. The size of the guide plate 16 can be set according to requirements and is not limited here.

[0023] Another clamping structure 10 is provided at the other end of the top of the base 1. The other end of the top of the base 1 is connected to a movable plate 8 via a hydraulic telescopic rod 7. The movable plate 8 is connected to the other clamping structure 10 via a bearing 9. The other clamping structure 10 and the movable plate 8 are in a movable connection state. The extension and retraction of the hydraulic telescopic rod 7 can change the position of the other clamping structure 10. The two guide plates 16 can position the fire protection engineering main pipe. When the pressure groove is placed, the pipe moves, improving the stability of the pipe. The cooperation of the two clamping structures 10 can realize the positioning and clamping of the fire protection engineering main pipe, so that the position of the fire protection engineering main pipe on the base 1 remains consistent and the processing accuracy is guaranteed.

[0024] A placement bracket 6 adapted to the fire protection main pipe is provided between the two clamping structures 10. The inner wall of the placement bracket 6 is provided with an isolation pad, which can be made of rubber, to prevent the coating on the surface of the fire protection main pipe from being scratched during movement and rotation, thus meeting the anti-corrosion requirements of the fire protection main pipe.

[0025] The bottom of the vertical inner side of the support plate 2 is evenly distributed with detection probes 12. During use, the detection probes 12 can be used to monitor the pressure groove in real time. The controller of this application can judge the quality of the pressure groove based on the detection data, and when the quality exceeds the tolerance, the controller of the device will automatically stop, which facilitates timely intervention by the staff and reduces the pipeline scrap rate. In one embodiment of this application, the detection probe 12 is a non-contact ultrasonic detector probe in the prior art. The non-contact ultrasonic detector connected to the detection probe 12 can be set at a suitable position of the device, which is not limited here.

[0026] A lifting frame 11 is connected to the middle of the horizontal section of the support plate 2 via a hydraulic telescopic rod 4. The bottom end of the lifting frame 11 is equipped with a grooving roller adapted to the grooves processed in the fire protection engineering main pipe. The extension and retraction of the hydraulic telescopic rod 4 changes the position of the lifting frame 11. When the lifting frame 11 moves, it drives the grooving roller to move, allowing the grooving roller to groove the pipe. Furthermore, the controller of this device can dynamically adjust the grooving depth of the grooving roller based on the detection results of the detection probe 12, reducing the impact of pipe thickness tolerances.

[0027] The grooving roller has a split structure, including a central part 18 connected to the lifting frame 11 and a replacement part 5 connected to the central part 18 through a connecting structure. One end of the central part 18 is provided with a bearing 2 19. The grooving roller is connected to the lifting frame 11 through the bearing 2 19. The grooving roller and the lifting frame 11 are in a movable connection state.

[0028] The connecting structure is located on the central part 18, and a fixing groove is provided on the inner wall of the replacement part 5. This arrangement avoids the connecting structure affecting the use of the replacement part 5. In one embodiment of this application, the connecting structure includes a double-ended ball screw 20 movably connected to the inner cavity of the central part 18, a gear 22 fixedly connected to the middle of the double-ended ball screw 20, and a gear plate 23 meshing with the gear 22. The gear plate 23 is movably connected to the inner cavity of the central part 18. Ball nuts 21 are threadedly connected to the outer rings at both ends of the double-ended ball screw 20. A fixing tube 24 is fixedly connected to the end of the ball nut 21 away from the gear 22. The fixing tube 24 is adapted to the fixing groove. When the gear plate 23 moves, it can carry... The rotating gear 22 drives the connected double-ended ball screw 20 to rotate. The rotation of the double-ended ball screw 20 causes the threaded ball nut 21 to move in the direction of the double-ended ball screw 20. The ball nut 21 drives the connected fixed tube 24 to move. When the fixed tube 24 is inserted into the fixed groove, the replacement part 5 is connected to the center part 18. When the fixed tube 24 is separated from the fixed groove, the replacement part 5 is quickly removed from the center part 18, which facilitates the replacement of the replacement part 5.

[0029] The toothed plate 23 is connected to the center part 18 by bolts 25, which fixes the position of the toothed plate 23 and improves the reliability of the connection between the replacement part 5 and the center part 18.

[0030] In practical use, to facilitate the alignment of the fixing groove and the fixing tube 24, positioning arrows can be provided on the side walls of the central part 18 and the replacement part 5. When the two positioning arrows are aligned, the fixing groove and the fixing tube 24 are aligned.

[0031] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0032] In summary: When using the automatic pressure trough device for fire protection main pipes, the operator places the fire protection main pipe to be pressured on the placement bracket 6. The hydraulic telescopic rod 7 drives the moving plate 8 to move. The moving plate 8 drives another clamping structure 10 to approach the fire protection main pipe. The inner support block 13 in the other clamping structure 10 can be inserted into the inner cavity of the fire protection main pipe. When the guide plate 16 contacts the fire protection main pipe, the continued operation of the hydraulic telescopic rod 7 can push the guide plate 16 to move the fire protection main pipe horizontally until the other end of the fire protection main pipe is tightly fitted with the guide plate 16 in the clamping structure 10. The length of the hydraulic telescopic rod 7 remains unchanged. The double-headed cylinder 17 works, and the double-headed cylinder 17 drives the inner support block 13 connected to it to move until the inner support block 13 is tightly fitted with the inner wall of the fire protection main pipe. The cooperation of the two clamping structures 10 achieves the clamping and fixing of the fire protection main pipe. The hydraulic telescopic rod 4 drives the pressing roller to move downwards. After the pressing roller contacts the surface of the fire protection main pipe, the controller inside the device drives the servo motor 3 to work. The servo motor 3 drives the fire protection main pipe to rotate through the clamping structure 10 connected to it. The controller inside the device controls the hydraulic telescopic rod 4 to work. The hydraulic telescopic rod 4 drives the pressing roller to press the fire protection main pipe to achieve grooving. During the grooving process, the detection probe 12 monitors the grooving situation in real time. The controller inside the device can dynamically adjust the downward pressure of the hydraulic telescopic rod 4 according to the detection results to eliminate the influence of pipe thickness. In addition, when the deviation is exceeded, the controller inside the device controls the device to stop, so that the staff can intervene in time and reduce the pipe scrap rate.
