Two first sliders 13 are provided at both ends of the upper frame 1 and the lower frame 2. Track limit wheels 37 are provided on both sides of the upper frame 1 to ensure that when the upper frame 1 is in contact with the hanger track, the limit wheels 37 prevent the rollers 5 from disengaging from the hanger track. The lifting frame includes a second column 14 and a U-shaped frame 15. There are four second columns 14, arranged in pairs. The tops of two second columns 14 in the same group are connected by a connecting beam 38 to ensure the structural strength of the second columns 14 and thus ensure stability. Each second column 14 is provided with a first guide rail 16. The second columns 14 are slidably connected to the first sliders 13 at the ends of the upper frame 1 and the lower frame 2 through the first guide rail 16. The bottom ends of the second columns 14 and the U-shaped frame 15 are connected to the cross frame 17. The top of the U-shaped frame 15 is connected to the first lead screw 12 through a lead screw and nut pair. Both ends of the cross frame 17 are provided with a second lead screw 18 and a second right-angle steering box 19 along the length direction. One end of the second lead screw 18 is connected to the output shaft of the second right-angle steering box 19. The input end of the second right-angle steering box 19 is provided with a third motor 20. The two sides of the lower surface of the cross frame 17 are provided with second guide rails 21. Each of the four corners of the upper surface of the cross frame 17 is connected to a diagonal tie rod 22. The end of the diagonal tie rod 22 away from the cross frame 17 is connected to the corresponding second column 14. There are two flip clamping frames 23, each of which is engaged with the second lead screw 18 via a lead screw and nut pair. The top of the flip clamping frame 23 is slidably connected to the second guide rail 21 via the second slider 24. A fourth motor 25 is provided on the outside of the flip clamping frame 23.

The output shaft of the fifth motor 34 and the top of the third lead screw 31 are both provided with sprockets 35. The two sprockets 35 are connected by a chain 36. The third lead screw 31 is driven to rotate through the cooperation of the fifth motor 34, the two sprockets 35, and the chain 36. The third lead screw 31, in cooperation with the lead screw nut pair, drives the movable clamping seat 30 to rise and fall, thereby realizing the clamping of the end of the frame.

[0016] Working method and operating principle: The first motor 7, the first bidirectional steering box 6, and the two universal joints 8 work together to drive the two corresponding rollers 5 to rotate, thereby enabling the mobile frame to move along the suspended track. The second motor 10, the second bidirectional steering box 9, and the two first right-angle steering boxes 11 drive the two first lead screws 12 to rotate. The first lead screws 12 cooperate with the lead screw nut pair at the top of the U-shaped frame 15 to realize the lifting and lowering of the U-shaped frame 15. Since the U-shaped frame 15 is connected to the cross frame 17, the cross frame 17 is also lifted and lowered. The cross frame 17 is slidably connected to the sliders on the outside of the upper frame 1 and the lower frame 2 through four second columns 14 to ensure stability. The second lead screw 18 is rotated by the cooperation of the third motor 20 and the second right-angle steering box 19. The flip clamp 23 is engaged with the second lead screw 18 through the lead screw nut pair, and then with the second guide rail 21 on the lower surface of the cross frame 17 through the second slider 24, so that the flip clamp 23 can move along the second guide rail 21, thereby realizing the approach and distance of the two flip clamps 23. When the two flip clamps 23 are located at both ends of the frame, they move closer to each other, and the two ends of the frame are supported on the fixed base plate 29 of the gripper. The third lead screw 31 is rotated by the cooperation of the fifth motor, two sprockets 35 and a chain 36, thereby realizing the downward pressing of the movable clamp 30 and completing the clamping of the frame. The fourth motor 25 is started. The fourth motor 25 drives the driven gear 27 to rotate through the driving gear 26, thereby realizing the flipping of the clamping frame, and then realizing the gripper driving the frame to flip. The first lead screw 12, the second lead screw 18 and the third lead screw 31 are also connected to the lead screw seat to ensure the stability of each lead screw. This utility model has a reasonable structure. The movable frame enables the overall lateral movement, and the lifting frame drives the cross frame 17 to rise and fall. The two second lead screws 18 work together to move the two flip clamping frames 23 closer to or further away from the cross frame 17 to clamp the frame. The clamping jaws of each frame clamp the ends of the frame. Then, the fourth motor 25, the drive gear 26, and the driven gear 27 work together to flip the jaws and the frame, greatly improving flexibility. No additional flipping machine is needed, reducing costs and greatly improving efficiency. Each of the four corners of the upper surface of the cross frame 17 is connected to a diagonal tie rod 22. The end of the diagonal tie rod 22 away from the cross frame 17 is connected to the corresponding second column 14. The diagonal tie rod 22 greatly improves the stability of the second column 14, thereby ensuring the overall structural stability.
