Special lifting tool for horizontal type clamp and method

Abstract

The invention discloses a special lifting tool for a horizontal type clamp and a method using the special lifting tool for lifting heavy weights apart from steel coils. The lifting tool comprises lifting cross beams, a lifting hook cross beam and a lifting hook. The lifting cross beams are symmetrically arranged left and right and the opposite ends of the lifting cross beams are provided with shaft holes. The two ends of the lifting hook cross beam are connected between the two lifting cross beams through the shaft holes. The lifting hook is hung in the middle of the lifting hook cross beam. The two ends of each lifting cross beam are of a square hollow structure matched with the sizes of hook-heads of the clamp. The special lifting tool for the horizontal type clamp is matched with the horizontal type clamp to be used; when the horizontal type clamp is not disassembled, the lifting hook of the special lifting tool is capable of lifting and conveying the heavy weights such as spare parts, equipment and waste side crops apart from the steel coils conveniently, safely and reliably. The special lifting tool is particularly suitable for production occasions where an original horizontal type clamp needs to be disassembled and assembled so that the heavy weights apart from the steel coils can be lifted and conveyed, and the phenomenon that the production efficiency is influenced by disassembling and assembling the horizontal type clamp is reduced. The special lifting tool for the horizontal type clamp and the method have the advantages of being reasonable in design, safe, reliable, easy to operate, and capable of improving the labor productivity effectively.

Description

technical field [0001] The invention relates to a hoisting device and a hoisting method, in particular to a special hoisting device and method for a horizontal tong, belonging to the technical field of cranes. Background technique [0002] In the production of the cold rolling production line, it is very frequent to use the crane horizontal clamp to lift steel coils. The production links such as the storage of steel coil raw materials, the loading and unloading of each unit production line, and the delivery of finished coils are all hoisted by horizontal clamps. When transporting steel coils, the horizontal clamp is connected to the crane hook through a pin shaft, and the control cable of the horizontal clamp is connected to the control system of the crane through the control box. Since the horizontal clamp can only be used to lift steel coils, on-site When it is necessary to lift heavy objects such as spare parts, equipment and waste materials, it is necessary to remove the...

AI Technical Summary

Problems solved by technology

The disassembly and assembly of the horizontal clamp is very troublesome and time-consuming. It is necessary to disassemble the pin shaft connecting the horizontal clamp and the crane hook, and the control circuit of the clamp needs to be disassembled. The operation is time-consuming and laborious, which affects the on-site production rhythm and output. When the site is busy, sometimes when the site operation is lifting heavy objects other than steel coils such as re-separated coils, scrap edge wire coils, etc., the steel wire rope is directly hung on the hook head of the horizontal clamp without removing the horizontal clamp. , it is easy for the wire rope to scratch the hook head of the horizontal clamp and the wire rope slips from the hook head of the horizontal clamp, causing the lifting object to fall and damage the equipment or cause personal injury, which poses a great safety hazard
