Large structural member sling system and hoisting method

Abstract

The invention discloses a large structural member sling system and a hoisting method. The sling system comprises at least one group of sling components, wherein each group of the sling components comprises two annular lifting ropes, and each lifting rope comprises a plurality of wires, a lifting hook and four lifting lugs; each wire is made from polyethylene plastic materials with ultra-high molecular weight; each lifting hook comprising four hooks; the four lifting lugs are arranged on a large structural member; when the large structural member is lifted, each annular lifting rope penetrates through two lifting lugs at one side of the large structural member; two parts, located between the two lifting lugs, of the lifting rope are hung on the two hooks, located at one side of the two corresponding lifting lugs, of the lifting hook separately. Compared with an existing hoisting method that steel wire ropes are directly wound the lifting hook, the hoisting method that annular steel wire ropes are directly hung on the lifting hook, and the hoisting method that the steel wire ropes are used for hoisting after the lifting hook is used for suspension aided by horizontal slings, the sling system has the advantages of easy hoisting, adjustment and leveling, and can be used for providing stable tensile force for the large structural member; and the hoisting stability and the hoisting efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting tool system and a hoisting method for large components. Background technique [0002] Existing large-scale components, such as large-scale T-beams and box girders of more than hundreds of thousands of tons, are generally hoisted by lifting equipment such as gantry cranes and beam lifters to realize movement and installation. When it comes to the installation of large components, whether the structural component remains stable and reliable when it is hoisted by a crane for a long time will directly affect the installation accuracy and efficiency of the large component. [0003] The existing hoisting methods for such large components generally adopt the following methods: [0004] 1. Directly wind the steel wire rope on the hook and then connect the large component; the problem brought by this method is that because the general large component exceeds 100 tons and weig...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the hoisting method of the existing hook directly winding the steel wire rope, the hoisting method of directly hanging the ring wire rope on the hook and the auxiliary horizontal rigging of the hook when hoisting the large components in the prior art. In the method of connecting large components by wire ropes, it is difficult to level the large components when the force of the sling is uneven, thus affecting the above-mentioned shortcomings of the stability of hoisting. A sling system for large components is provided, and a A kind of hoisting method of this large-scale component with sling system
