Lifting steering device for standardizing iron tower assembling and erection

Abstract

The invention belongs to the technical field of power transmission line engineering iron tower construction tools, and particularly relates to a lifting steering device for standardizing iron tower assembling and erection. The lifting steering device for standardizing iron tower assembling and erection comprises a pulling force steering flange plate, a tower foot plate and a fire bending pulling force steering plate, wherein connecting holes are formed in the two sides of the fire bending pulling force steering plate; one end of the fire bending pulling force steering plate is directly connected with a construction hole formed in the tower foot plate; an eye hole is formed in the pulling force steering flange plate; a first U-shaped ring is connected outside the eye hole through a bolt; and a bearing rope is hinged between the first U-shaped ring and the fire bending pulling force steering plate. The lifting steering device for standardizing iron tower assembling and erection is simple in shape, low in cost, easy to machine and operate, time-saving, labor-saving, and capable of guaranteeing quality, standardizing safe and civilized construction and eliminating potential safety hazards of tower assembling and erection; and safe and civilized construction is standardized, the civilized production requirement is met, and the assembling and erection time of each foundation of iron tower can be greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of iron tower construction tools for electric power transmission line engineering, and in particular relates to a standard iron tower erection hoisting and steering device. Background technique [0002] At present, during the construction of iron towers in power transmission line projects, construction personnel analyze the difficulties in the construction of iron towers according to the design characteristics of transmission lines with different voltage levels. Completed the construction project on schedule, standardized the hoisting and steering accuracy of the iron tower assembly, and made countless optimization improvements in the first pass rate; in addition, in order to eliminate the uncivilized production behavior of tying steel wire ropes on the tower legs, the steel wire sleeves were sheared and broken. At the same time, corresponding improvements have been made to the defects of tower material wear...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a standardized hoisting and steering device for iron tower assembly, so as to solve the problem that the support rope binds the steel wire sleeve on the tower leg, which will cause wear and tear on the tower material, damage to the plating skin and motorized twisting and grinding of the reel in the direction of the rope. Potential safety hazards in the overlapping winding of the upper steel wire rope
