Description

Technical Field

[0001] The utility model relates to a hoisting device, in particular to a multifunctional movable adjustable truss hoisting device, belonging to the technical field of hoisting devices. Background Art

[0002] When a large truss is being hoisted, it will be split into multiple units, and the multiple units will be hoisted and spliced ​​one by one, which can reduce the difficulty of hoisting and splicing the truss. The existing hoisting and splicing is to lift the split truss to the same height as the fixed truss by a crane, and then adjust the position of the truss to align the splicing ends between the truss and the fixed truss, and then manually splice and fix it. In steel structure construction, the truss is usually connected to the steel column through a corbel. After the truss is assembled on the ground or hoisted after the whole frame is brought to the site, the webs on both sides of the truss are usually connected to the steel column and truss by a single filler to ensure that the truss reaches the designed state. However, when encountering a truss with a small number of webs, the webs on the far side of the truss are installed later, resulting in the inability to form a stable structural system when the truss is assembled, which brings great inconvenience to the on-site installation.

[0003] If the above situation occurs, the trusses can only be installed in bulk at high altitude, which will lead to slow construction speed and increase the amount of high-altitude work. In addition, the above method consumes relatively more time and manpower for the construction of the trusses, greatly increasing the risk sources and construction costs of on-site construction. Utility Model Content
