Description

Technical Field

[0001] This utility model relates to the field of flange repair technology, and in particular to a reactor flange sealing surface repair device. Background Technology

[0002] Reactor flanges often use tongue and groove or complex surface seals to adapt to the harsh working conditions of high temperature, high pressure, high corrosion and flammable and explosive media. However, these types of seals have high requirements for machining and fitting precision, are easy to damage and difficult to repair.

[0003] There are two existing repair methods: manual repair using forming milling cutters, which is inefficient and has poor precision; and machine tool operation using CNC floor-type milling and boring machines, which has higher precision but a longer cycle and higher cost, making it difficult to balance efficiency and cost. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a reactor flange sealing surface repair device, which aims to improve the problem that traditional repair methods are difficult to balance between efficiency and cost.

The position is determined by the laser rangefinder, and the limiting structure on one side of the mounting block is opened to limit the inner wall of the flange. The servo motor drives the protective box, connecting rod, and moving structure to rotate.

[0013] Preferably, one side of one of the protective covers is fixedly connected to the top of the slider, and one side of the other protective cover is fixedly connected to one side of the mounting block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the flange is placed into the limiting structure at the top of the slider for limiting. The slider is slid to a suitable position, and the lifting machine drives the limiting structure on one side of the mounting block to descend to a suitable position.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-5 This utility model provides an embodiment of a reactor flange sealing surface repair device, including a base plate 1, a slide rail 2 symmetrically fixedly connected to the top of the base plate 1, a slider 3 slidably connected to one side of the slide rail 2, a lift 11 fixedly connected to one side of the base plate 1, a servo motor 10 fixedly installed on one side of the lift 11, a protective box 9 fixedly connected to the output end of the servo motor 10, a moving structure fixedly connected to one side of the protective box 9, a laser rangefinder 16 fixedly connected to the inner wall of the protective box 9, a connecting rod 8 fixedly connected to the bottom of the protective box 9, an mounting block 7 rotatably connected to the outer wall of the connecting rod 8, and a limit structure fixedly connected to one side of the mounting block 7 and the top of the slider 3.

[0026] Specifically, by placing the flange into the limiting structure at the top of the slider 3 to limit the outer wall of the flange, the slider 3 is slid on the slide rail 2 to a suitable position. The lifting platform 11 drives the servo motor 10, which in turn drives the connecting rod 8 and the mounting block 7, causing the limiting structure on one side of the mounting block 7 to descend to a suitable position. The laser rangefinder 16 determines the position accuracy, and the limiting structure on one side of the mounting block 7 is opened to limit the inner wall of the flange. By turning on the servo motor 10, the servo motor 10 drives the protective box 9, the connecting rod 8, and the moving structure to rotate. The moving structure drives the milling cutter or welding head mounted on the moving structure to the position that needs to be repaired, completing the turning or welding. This improves the problem of the traditional repair method's difficulty in balancing efficiency and cost.

[0027] Reference Figure 1 , Figure 3 The movable structure includes a second connecting block 18. One side of the second connecting block 18 is fixedly connected to one side of the laser rangefinder 16. A second servo motor 17 is fixedly installed on the other side of the second connecting block 18. A lead screw 15 is fixedly connected to the output end of the second servo motor 17. The lead screw 15 is rotatably connected to the inner wall of the protective box 9. A limit block 13 is fixedly connected to one end of the lead screw 15. A connecting frame 12 is fixedly connected to one side of the protective box 9. The outer wall of the limit block 13 is rotatably connected to one side of the connecting frame 12. A first connecting block 14 is threadedly connected to the outer wall of the lead screw 15. One side of the first connecting block 14 is slidably connected to one side of the connecting frame 12.

[0028] Specifically, by starting the servo motor 17, the lead screw 15 is driven to rotate inside the protective box 9. The connecting bracket 12 is used to limit the movement, so that the connecting block 14 moves forward or backward on the outer wall of the lead screw 15 according to the rotation direction of the lead screw 15. This drives the milling cutter or welding head installed on the connecting block 14 to move to the appropriate position. The laser rangefinder 16 installed on the protective box 9 can help to accurately detect and locate damage on the flange.

[0029] Reference Figure 4 , Figure 5The limiting structure includes two protective covers 4. A connecting plate 5 is fixedly connected to one side of the protective cover 4. A servo motor 26 is fixedly installed on one side of the connecting plate 5. A worm 24 is fixedly connected to the output end of the servo motor 26. A limiting block 25 is rotatably connected to the outer wall of the worm 24. One side of the limiting block 25 is fixedly connected to one side of the connecting plate 5. A worm wheel 23 is meshed with the tooth end of the worm 24. A rotating shaft 22 is fixedly connected to one side of the worm wheel 23. The outer wall of the rotating shaft 22 is rotatably connected to the inner wall of the connecting plate 5. A limiting block 21 is fixedly connected to one side of the rotating shaft 22. A connecting rod 20 is slidably connected to the inner wall of the limiting block 21. A curved panel 6 is fixedly connected to one side of the connecting rod 20. A connecting plate 29 is fixedly connected to one side of the rotating shaft 22. One side of one protective cover 4 is fixedly connected to the top of the slider 3, and one side of the other protective cover 4 is fixedly connected to one side of the mounting block 7.

[0030] Specifically, the servo motor 26 inside the two limiting structures of different sizes drives the worm gear 24 to rotate, which in turn drives the worm wheel 23 to rotate, causing the rotating shaft 22 to rotate on the inner wall of the connecting plate 5. Through the tooth end structure of the worm wheel 23 and the worm gear 24, the worm wheel 23 can drive the rotating shaft 22 to rotate, while the rotating shaft 22 cannot drive the worm wheel 23 to rotate, achieving a non-reverse effect. The rotating shaft 22 drives the limiting block 21 to rotate, and the connecting rod 20 sliding in the groove of the limiting block 21 drives the curved plate 6 to expand outward or contract inward. The connecting plate 29 lifts the flange, and the curved plate 6 contracts inward or expands outward to lock the flange, thus completing the limiting of the flange.

[0031] Working principle: In use, the flange is placed on the connecting plate 19 on the top of the slider 3. The servo motor 26 drives the worm gear 23 to rotate, which in turn drives the limit block 21 to rotate, causing the curved panel 6 to retract inward and lock onto the outer wall of the flange. The slider 3 is slid to the appropriate position, and the lifting machine 11 drives the curved panel 6 on one side of the mounting block 7 to descend to the appropriate position. The laser rangefinder 16 confirms the position accuracy. The servo motor 26 on one side of the mounting block 7 is turned on to lock onto the inner wall of the flange. The servo motor 10 is turned on, causing the protective box 9, connecting rod 8, and lead screw 15 to rotate. The servo motor 17 is started to drive the lead screw 15 to rotate. The connecting bracket 12 limits the movement, causing the connecting block 14 to move forward or backward, which moves the milling cutter or welding head installed on the connecting block 14 to the appropriate position. The laser rangefinder 16 installed on the protective box 9 can help to accurately detect and locate damage on the flange, completing the repair of the reactor flange sealing surface.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
