A lower clamping plate 4 is fixedly connected to the top of each fixing block 3. A limiting groove 5 is opened on the top right side of the movable base 1, and the limiting groove 5 extends left and right. A support rod 6 is provided on the top right side of the limiting groove 5. The support rod 6 is U-shaped, and the bottom end of the support rod 6 slides with the top of the movable base 1. A slider 7 is provided on the top left side of the limiting groove 5. The bottom of the slider 7 is inside the limiting groove 5. The bottom of block 7 slides within the limiting groove 5. The tops of support rod 6 and slider 7 are both fixedly connected to lower clamping plate 2 8. Lower clamping plate 1 4 and lower clamping plate 2 8 have the same shape. Several connecting rods 10 are fixedly connected between the opposite side walls of the two lower clamping plates 1 4 and between the opposite side walls of the two lower clamping plates 2 8. The connecting rods 10 are evenly distributed. The top front ends of lower clamping plate 1 4 and lower clamping plate 2 8 are rotatably connected to the bottom of opening and closing plate 11. Opening and closing plate 11 is U-shaped. Connecting plates are fixedly connected between the tops of the two opening and closing plates 11 on the left and between the tops of the two opening and closing plates 11 on the right. A socket 17 is formed at the top center of the opening and closing plate 11. A plug 18 is slidably inserted into the socket 17. The plug 18 extends vertically. The top center of the connecting plate 16 is rotatably connected to the bottom of the threaded rod 20. The threaded rod 20 passes through the center of the connecting plate 29. The outer wall of the threaded rod 20 is threadedly connected to the connecting plate 29. The left and right ends of the connecting plate 29 are fixedly connected to the tops of the plugs 18 on both sides. A throttle 21 is fixedly connected to the top of the threaded rod 20. A pressure plate 22 is fixedly connected to the bottom of the plug 18. The front and rear ends of the two pressure plates 22 on the left are fixedly connected to the inclined plates. The front and rear ends of the two pressure plates 22 on the right side are fixedly connected to the diagonal bracing plate 24. The diagonal bracing plate 23 and diagonal bracing plate 24 on the front side are inclined forward and downward, and the diagonal bracing plate 23 and diagonal bracing plate 24 on the rear side are inclined backward and downward. Four fixing holes 25 are opened on the outer wall of the diagonal bracing plate 24. The fixing holes 25 are arranged in a rectangular shape. Multiple fixing holes 26 are opened on the front and rear outer walls of the lower clamping plate 28. The fixing holes 26 are evenly distributed in two rows. Rollers 27 are provided in both the fixing holes 25 and the fixing holes 26. The rollers 27 are rotatably connected to the lower clamping plate 28 and the diagonal bracing plate 24.

[0016] The lower part of the lower clamping plate 4 is straight. The front and rear ends of the lower part of the lower clamping plate 4 extend upward and tilt outward. The right end of the moving seat 1 is fixedly installed with an electric push rod 9. The output shaft of the electric push rod 9 is fixedly connected to the right side wall of the slider 7. There is a gap between the outer wall of the electric push rod 9 and the support rod 6.

[0017] The outer rear wall of the opening and closing plate 11 is fixedly connected to the fixing plate 12. The outer rear walls of the lower clamping plate 14 and the lower clamping plate 28 are both fixedly connected to the fixing plate 23. The fixing plate 12 and the fixing plate 23 are staggered. The left and right outer walls of the fixing plate 12 and the fixing plate 23 are provided with insertion holes 14. The pins 15 are inserted into two adjacent insertion holes 14.

[0018] The ends of pipe 28 and pipe 29 are respectively equipped with flanges. Pipe 29 and pipe 28 are placed on lower clamping plate 4 and lower clamping plate 8 respectively. Since the position of lower clamping plate 4 is fixed, lower clamping plate 8 can slide in the limiting groove 5 through slider 7 and support rod 6.

[0019] In the initial state, the opening and closing plate 11 is in the open state, allowing tube 29 and tube 1 28 to be placed on the lower clamping plate 4 and lower clamping plate 2 8 respectively, and the opening and closing plate 11 is closed.

[0020] Use pin 15 to pass through the insertion holes 14 of fixing plate 12 and fixing plate 2 to fix the position of the opening and closing plate 11 and the flange.

[0021] Turning the handle 21 causes the threaded rod 20 to rotate, which in turn pushes the connecting plate 2 19 and the insert 18 to move downward. The pressure plate 22 at the bottom of the insert 18 presses the pipe 2 29 and the pipe 1 28 tightly onto the lower clamping plate 1 4 and the lower clamping plate 2 8, respectively.

[0022] Diagonal bracing plate 1 23 and diagonal bracing plate 24 provide additional support and stability, ensuring that pipe 2 29 and pipe 1 28 do not move during flange connection.

[0023] The electric push rod 9 is used to push the slider 7, which causes the lower clamping plate 2 8 and the tube 28 on it to move to the left until the two flanges are close together.

[0024] Rotate pipe 28 using external equipment to ensure that the holes on the two flanges are basically aligned.

[0025] By rolling the roller 27 within the fixing hole 25 and fixing hole 26, the pipe 28 on the lower clamping plate 28 can be rotated to ensure that the flange hole on the pipe 28 is aligned with the flange hole on the pipe 29.

[0026] Once the flange holes are fully aligned and secured, bolts or other fasteners can be used to fix the two flanges together through the flange holes. This utility model only protects the mechanical parts; functions implemented through software control are not within the scope of protection of this utility model.
