Problems solved by technology

[0002] Steel components such as long-span steel trusses have become a fast-growing structure type due to their small weight, short construction period, high safety, and especially the characteristics of maximizing building functions, and their installation and manufacturing requirements are high. The installation is difficult, and the vertical rotation of the steel member needs to be realized by using a sliding jacking system. At present, during the vertical rotation, there will be a large additional load on the steel member, which makes the force uneven and affects the vertical rotation of the steel member. Stability; in addition, it is necessary to use a hydraulic lifter to lift the steel member. The installation stability of the existing hydraulic lifter is poor, which affects the bearing reliability of the steel member during the lifting process

Abstract

The invention discloses a vertical rotation lifting system for steel members. The vertical rotation lifting system involves a vertical rotation pushing device and a lifting device, wherein the vertical rotation pushing device comprises a hydraulic crawler, a hydraulic oil cylinder, a sliding rail and a sliding shoe, and the lifting device comprises two hydraulic lifters and a lifting tower; and the lifting tower comprises six tower main limbs, a first supporting rod, a second supporting rod, a triangular first supporting frame, a triangular second supporting frame, a lifting beam and a plurality of first connecting rods. In this way, according to the vertical rotation lifting system for the steel members, the additional load on the steel members such as a steel truss is small, uniform stress is guaranteed, and therefore the vertical rotation stability of the steel members is guaranteed; and the bearing reliability of the steel members in the lifting process can be guaranteed.
