Combined lifter for lifting steel parts

Abstract

The invention discloses a combined lifter for lifting steel parts, which comprises two side beams, a foundation beam and extended boards, wherein the two side seams are respectively provided with at least one connecting hole, a top beam arranged on the top ends of the side beams is symmetrically welded on the side beams together, a lug plate for connecting rings is welded on the upper surface of the top beam corresponding to the side beams, at least two inner thread holes on which puller bolts are penetratively arranged are arranged at the middle of the top beam, the extended boards are connected to both sides of the foundation beam through pin shafts, connecting holes corresponding to the side beams are arranged on the extended boards, and the extended boards are connected with the side beams through fasteners penetratively connected to the connecting holes. The invention has the advantages of simple structure, simple and easy operation, flexible assembly and disassembly, reuse capability, uniform force for steel parts and high lifting safety factor and no damage to steel parts, avoids follow-up remediation due to base material damage, simplifies lifting process, reduces labor intensity, increases work efficiency and saves construction cost.

Description

technical field [0001] This invention relates to load-hanging elements or devices attached to or connected to crane lifting, lowering or traction mechanisms for transmitting lifting forces to objects, and in particular to a Spreaders for steel members of various shapes and sizes. Background technique [0002] At present, for the hoisting methods of steel components, the following three schemes are usually adopted, all of which will have different effects on the quality and safety of components, and all have some defects: [0003] The first is to directly put the steel member on the steel member for lifting with a steel wire rope. The disadvantage is that due to the small contact area, it is easy to wear the paint surface of the steel member and is prone to decoupling. The second is to directly put the steel member on the lifting belt for lifting, such as figure 1 As shown, although this method can effectively protect the appearance of the steel member, it is also prone to ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the technical problem that the steel components in the prior art are prone to slipping, or the paint surface of the steel components is easily worn, or the operation is complicated. It provides a combined hoisting tool for hoisting steel components.
