A hook device for integral erection of a high-voltage transmission line iron tower and its use method

Abstract

The invention discloses a hook device for the overall assembly of a high-voltage transmission line iron tower, which includes a hoisting frame. The top is equipped with a winding device, a hook device for the overall assembly of a high-voltage transmission line iron tower and its use method. The present invention provides a hook device capable of automatic bridging and unhooking of the integrated assembly of the Kono circuit. , using the steel cable structure that can be rolled up, the internal steel cable can be automatically extruded when decoupling, so as to realize automatic decoupling. With a lifting steel cable structure that does not need to be disassembled, the hook and the lifting steel cable can be connected on the ground Separation, minus the long time brought by the construction personnel on the tower to remove the hook, seriously affects the construction period, which is equivalent to reducing the number of iron towers by 40%. The working link of installation is not conducive to the problem of safety production.

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.
