Overall assembly lifting hook device for high-voltage transmission line iron tower and use method of overall assembly lifting hook device

Abstract

The invention discloses a high-voltage transmission line iron tower integral assembly lifting hook device which comprises a lifting frame, a lifting hook is welded to the lower surface of the lifting frame, a connecting steel cable is assembled on the arc-shaped inner wall of the front end of the lifting hook in an attached mode, and a winding device is assembled at the top end of the connecting steel cable. According to the lifting hook device capable of achieving automatic bridging and unhooking for the high-field circuit overall assembly, when the lifting hook device is used, the steel cable structure capable of being rolled is utilized, the steel cable in the lifting hook device can be automatically extruded out during unhooking, and therefore automatic unhooking is achieved. The lifting hook and the lifting steel cable can be separated on the ground, and the problems that time is long, the construction period is seriously affected, the number of iron tower assemblage is equivalently reduced by 40%, economical efficiency is poor, the working link that constructors repeatedly climb to the tower to disassemble and assemble is increased, and safety production is not facilitated are solved.

Description

technical field [0001] The invention relates to the field of integral assembly of iron towers for high-voltage transmission lines, in particular to a hook device for integral assembly of iron towers for high-voltage transmission lines and a method for using the same. Background technique [0002] The method of erecting the iron tower as a whole on the traditional transmission line is to use the crane hook to hang on the steel wire rope that binds the tower head position, and then carry out lifting and erection. The work of overall assembly, but because the construction personnel take a long time to disassemble the steel wire rope on the tower, it seriously affects the construction period, which is equivalent to reducing the number of iron tower assembly by 40%, and the economy is poor. And it increases the work link of the construction personnel repeatedly going up and disassembling the tower, which is not conducive to safe production. In view of the above problems, a hook d...

Problems solved by technology

[0002] The method of erecting the iron tower as a whole on the traditional transmission line is to use the crane hook to hang on the steel wire rope that binds the tower head position, and then carry out lifting and erection. The overall assembly work, but because the construction personnel take a long time to disassemble the steel wire rope on the tower, it seriously affects the construction period, which is equivalent to reducing the number of iron tower assembly by 40%, and the economy is poor

In addition, it increases the construction personnel's repeated steps of dismantling and disassembling the tower, which is not conducive to safe production. In view of the above problems, a hook device and its use method for the overall assembly of the iron tower of the high-voltage transmission line are proposed.
