[0003] In the prior art, a mobile crane or a tower crane is often used. Since the boom and the wire rope of the mobile crane (tower crane) have a certain elasticity, the linear arc is large when the boom is raised and the rope is retracted, and repeated adjustments are required to basically meet the requirements, and the installation speed is slow;

[0004] Therefore, how to ensure the precise control of the installation angle of large-angle outward-inclined steel columns and speed up the installation speed is a difficult problem that technical personnel in this field have been thinking about. Utility Model Content

[0013] In some possible implementations, the driving mechanism is a jack, and a telescopic end of the jack is connected to the sliding frame.

[0014] In some possible implementations, the load-bearing rail is an H-shaped steel, including an upper flange plate, a web plate and a lower flange plate that are slidably matched with the sliding frame.

[0015] In some possible embodiments, the reaction frame is provided with a T-shaped slot with a T-shaped cross-section, including a small slot with an opening, and a large slot connected to the small slot at one end away from the opening and located in the reaction frame; the upper flange plate is located in the large slot, and the web plate passes through the small slot.
