The U-shaped plate 61 is slidably connected to the corresponding guide rails 14 through the sliding grooves 62 to ensure the stability and smoothness of the sliding process.

[0070] One end of each of the rotating rollers 63 is connected to the U-shaped plate 61 by a synchronous belt 2. The synchronous belt 2 is connected to the output end of the motor 2 installed inside the U-shaped plate 61, so that the motor 2 and the synchronous belt 2 can drive each of the rotating rollers 63 to rotate simultaneously, thereby supporting and correcting the lower flange plate of the H-shaped thin-walled steel structure 18 and conveying the entire H-shaped thin-walled steel structure 18.

[0071] In this embodiment, the bottom surface of the horizontal plate of the movable L-frame plate 3 is provided with a sliding groove 8 corresponding to the guide rail 4 15.

[0073] Specifically, when straightening the H-shaped thin-walled steel structure 18, the distance between the fixed L-frame plate 2 and the movable L-frame plate 3 is adjusted by hydraulic push rod four 17 according to the width of the flange plate of the H-shaped thin-walled steel structure 18, so that the distance between them corresponds to the width of the flange plate of the H-shaped thin-walled steel structure 18.

[0074] Based on the thickness of the web of the H-shaped thin-walled steel structure 18, the distance between the two web straightening mechanisms 6 is adjusted by hydraulic push rod 3 13 so that the distance between them corresponds to the thickness of the web.

[0075] Based on the thickness of the 18 flange plates of the H-shaped thin-walled steel structure, the distances between the corresponding lower flange plate straightening mechanism 5 and upper flange plate straightening mechanism 7 and the driven roller 32 and driven roller 42 are adjusted by hydraulic push rod 11 and hydraulic push rod 212 respectively, so that the distances between them correspond to the thickness of the 18 flange plates of the H-shaped thin-walled steel structure.

[0076] After adjustment, the upper flange of the H-shaped thin-walled steel structure 18 can pass between the upper flange straightening mechanism 7 and the driven roller 32; the lower flange of the H-shaped thin-walled steel structure 18 can pass between the lower flange straightening mechanism 5 and the driven roller 42; and the web of the H-shaped thin-walled steel structure 18 can pass between the two web straightening mechanisms 6, thus straightening the entire H-shaped thin-walled steel structure 18.
