[0030] The installation and use process of the C-type flipping frame structure for the flipping and repositioning device of this utility model is as follows:

[0031] 1. The installation process is as follows:

[0032] 1.1 First, the installer can assemble the C-shaped frame 1. Specifically, side plates 12 can be welded to both sides of the connecting plate 16. Then, a C-shaped frame 11 is attached along the outer edge of the side plate 12. The C-shaped frame 11 enhances the overall processing strength of the C-shaped frame 1. The C-shaped frame 11 is welded to the side plate 12. Next, a limiting frame 2 for limiting the frame is installed inside the U-shaped working space 6 of the C-shaped frame 1. Simultaneously, the beam clamping mechanism 3 is installed. Specifically, the bottom of the mounting support 31 is connected to the lower inner part of the U-shaped working space 6. Bearing seats 33 are installed on both sides of the mounting support 31. Support bearings supporting the adjusting screw 32 are installed inside the bearing seats 33. Then, both ends of the adjusting screw 32 are installed on the support bearings. Finally, the left clamping part 34 and the right clamping part 3 are installed on the adjusting screw 32. 5. Installation: First, the movable block 351 can be threaded onto the adjusting screw 32 through the threaded through hole. Then, the bearing plate 352 is installed on the movable block 351, and the positioning block 353 is installed on the bearing plate 352. The positioning block 353 is used to clamp and position the lower side of the crane beam, and the positioning block 353 has an L-shaped structure. After the above installation is completed, the mounting bracket 5 is installed in the opposite direction of the beam clamping mechanism 3. The pressing mechanism 4 is installed on the mounting bracket 5. Specifically, the working cylinder 41 can be installed on the mounting bracket 5, the cylinder rod 42 can be installed in the working cylinder 41, and the top of the pressing seat 43 can be installed at the outer end of the cylinder rod 42. At the same time, the guide sleeve 7 is installed on the mounting bracket 5, the guide rod 8 is installed in the guide hole in the guide sleeve 7, and the bottom of the guide rod 8 is connected to the pressing seat 43. Thus, the installation process of this utility model is completed.

[0033] 2.2.1 In practical use, the operator can use the external hoisting mechanism to lift the crane beam frame into the U-shaped working space 6 of the C-shaped frame 1. At this time, the bottom of the crane beam frame is on the mounting support 31 between the left clamping part 34 and the right clamping part 35. Then, the adjusting screw 32 in the beam clamping mechanism 3 can be controlled to rotate clockwise. At this time, under the action of the threaded pushing force, the moving block 351 in the left clamping part 34 on the adjusting screw 32 moves to the right, and the right clamping part 35 on the adjusting screw 32 moves to the right. The movable block 351 in part 35 moves to the left. When the movable block 351 moves, it can drive the bearing plate 352 and the positioning block 353 on it to move. When the positioning block 353 in the left clamping part 34 and the right clamping part 35 contacts and clamps the lower side of the crane beam frame (the operator can adjust the opening distance of the left clamping part 34 and the right clamping part 35 according to the use needs to meet the clamping of crane beam frames of different widths), the rotating adjustment screw 32 can be stopped. At this time, the clamping action of the beam clamping mechanism 3 on the lower side of the crane beam frame is completed.

[0034] 2.2 Subsequently, the operator can control the working cylinder 41 in the clamping mechanism 4 to start. The working cylinder 41 can control the cylinder rod 42 installed on it to move downward and extend outward. At this time, driven by the cylinder rod 42, the clamping seat 43 moves downward and contacts the top of the crane beam frame in the U-shaped working space 6, pressing the crane beam frame into the U-shaped working space 6. At this time, under the coordinated action of the beam clamping mechanism 3, the clamping mechanism 4 and the C-shaped frame 1, the stable clamping and positioning operation of the crane beam frame is completed, effectively avoiding the crane beam frame from falling when the C-shaped flipping frame structure flips, and ensuring the accuracy of the welding point. The above shows and describes the basic principle, main features and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principle of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
