[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets.

[0003] However, the existing steel structure straightening machines can only perform limit correction on both sides, without limiting the upper surface of the steel structure, which may cause the steel structure to shake or vibrate during transportation, affecting the accuracy and stability of the correction, and the guide plates on both sides of the front end face cannot be adjusted, which may not be able to adapt to steel structures of different sizes and shapes.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a steel structure straightening machine is proposed. Utility Model Content

The first roller 205 not only serves as a support point to limit the steel structure on the upper end surface, but also can be used as a conveying device to help the steel structure move in the straightening machine. Then, due to the design of the roller, the friction with the steel structure can be reduced, making the conveying smoother and ensuring that the steel structure maintains a stable posture during the conveying process to avoid up and down shaking and causing deviation.
