AI Technical Summary

Problems solved by technology

There are also the following problems: 1. Because the position of the super-long sling of the tower is close to the top of the tower, the body of the tower is subjected to excessive force when it is hoisted, which is easy to cause bending deformation; Dragging is easy to cause deformation and wear due to friction with the ground; 3. It is easy to cause the tower to sway during the lifting process, which has great potential safety hazards for people and mechanical equipment

Abstract

The invention relates to an integral hoisting method for a super-long tower, and belongs to the technical field of construction of power distribution lines. The technical scheme is as follows: a crane is matched with a four-wheel gun carriage; a lifting arm (15) of the crane (14) lifts the head of the tower; meanwhile, the four-wheel gun carriage moves towards the direction of a tower mounting foundation (23); in the moving process of the four-wheel gun carriage, the elevation angle of the root of the tower bound on a joist gradually increases, and the joist rotates along with the root of the tower; the tower is vertically lifted by the crane; the four-wheel gun carriage moves onto the tower mounting foundation (23); the tower is separated from the joist; and the tower is aligned on the tower mounting foundation (23) through the crane to finish installation of the tower. The integral hoisting method for the super-long tower has the beneficial effects of simple operation, labor and effort saving, high working efficiency, safety, stability, difficult suffering of the impact, friction and bending deformation phenomenon by all parts of the tower and an effective guarantee of personal safety and equipment safety.

Description

technical field [0001] The invention relates to an integral hoisting method of a super-long pole tower, which belongs to the technical field of power distribution line construction. Background technique [0002] At present, in the hoisting construction of ultra-long towers (more than 27 meters) for power transmission and distribution, people often use segmented group hoisting, and the overall hoisting construction often requires multiple cranes to cooperate with hoisting. The construction method of the background technology occupies many cranes, which is laborious and laborious, and the work efficiency is low. If a crane is used for overall hoisting. There are also the following problems: 1. Because the position of the super-long sling of the tower is close to the top of the tower, the body of the tower is subjected to excessive force when it is hoisted, which is easy to cause bending deformation; Dragging is easy to cause deformation and wear due to friction with the grou...
