A steel truss hoisting tool

Abstract

The invention discloses a steel truss hoisting tool, which is composed of a hoisting ring. A hanging plate is mounted on the hanging shaft of the hoisting ring. There is an insertion hole penetrating through the plate body from the thickness direction on the hanging plate. A hoisting pallet is installed, and both ends of the hoisting pallet protrude from the hanging board.

Description

technical field [0001] The invention relates to a hoisting tool and a hoisting process thereof, in particular to a steel truss hoisting tool and a steel truss hoisting process thereof. Background technique [0002] Due to the short construction period of steel structure construction, high degree of mechanization, high processing precision and high efficiency, and the recyclable use of steel is beneficial to environmental protection, more and more steel structures are used in the construction industry. [0003] At present, steel trusses in industrial buildings mostly adopt the process of hoisting in place as a whole. When hoisting, cranes (or masts), hooks, wire ropes and rigging shackles (commonly known as hoisting rings) are usually used to bind the upper and lower chords of hoisting steel trusses. Hoisting process method. This process method has two defectives: 1, because the edge angle of shaped steel cuts steel wire rope, so need to protect steel wire rope with sleeper ...

AI Technical Summary

Problems solved by technology

This process method has two defects: 1. Since the edges and corners of the section steel cut the wire rope, sleepers need to be used to protect the wire rope during hoisting, and iron wires are used to bind both sides of the section steel at the lifting point before hoisting

During translation and hoisting construction, it is necessary to change the position of the lifting point several times. If the position of the lifting point changes, it is necessary to re-bind the sleepers or bind the sleepers in multiple places, so the construction is very troublesome

2. The installation position of the steel truss is mostly inclined at a certain angle. When hoisting a single vehicle, the position of the lifting point and the length of the steel wire rope are determined by calculation, and the inclination angle of the truss is adjusted by using the difference between the lengths of the steel wire ropes at both ends. However, due to the structural characteristics of the truss, during the hoisting process It is particularly ideal to use the length of the wire rope to adjust the inclination angle of the truss, which is difficult to control. When the truss is hoisted in place, both ends of the truss cannot be in place at the same time. There is a safety hazard in the truss shaking caused by distribution
