Problems solved by technology

Selecting a pole with an appropriate length and lifting weight can meet the requirements of greater hoisting weight and longer longitudinal length of the hanger. However, since the pole in the prior art is arranged in the center of the tower position, and the inclination of the pole is limited, the size of the tower window of the iron tower In particular, the increase in the lateral dimension causes the hanger to be far away from the center of the tower, which is a difficult point to be solved in the hoisting scheme

Embodiment Construction

[0014] A kind of unit type assembly method of UHV transmission iron tower of the present invention, comprises the following steps:

[0015] Step 1. Clean up and arrange the construction site, construct the ground foundation, and transport the tower materials required for the erection of the iron tower

[0016] Put it in place; step 2, assemble the pole, erect the pole, and assemble the lower part of the tower leg. The section side width of the assembled pole is 800mm~900mm; when erecting the pole, first connect the four corners of the bottom of the pole to the On the basis, fix the stay wire and the pulley on the top of the pole to ensure that the center of the pole is on the same line as the traction ground anchor; step 3, assemble and erect the tower legs, lift the pole, and lift the components one by one. The binding points of the lifting components should be Set above the center of gravity of the suspended component, located at the symmetrical node between the two main mat...

Abstract

A unitary erection method of an ultra-high voltage transmission iron tower of the present invention, firstly cleans and arranges the construction site, constructs the ground foundation, and transports the tower materials required for erection of the iron tower; then assembles the poles, erects the poles, and assembles the tower For the lower part of the leg, the side width of the section of the assembled pole is 800mm~900mm; Pull the ground anchor on the same straight line; assemble and erect the tower legs, lift the pole, and lift the components one by one, lift the pole, hoist the tower head, install the ground wire bracket, hoist the tower cross arm piece by piece, install the tower accessories, Then remove the pole. The beneficial effects of the invention are: the invention provides technical support for the safe construction of the UHV test demonstration project, the improvement of work efficiency, and the realization of environmental protection goals.

Description

technical field [0001] The invention relates to a unitary assembling method of an ultra-high voltage transmission iron tower. Background technique [0002] At present, research on the erection process of UHV iron towers is rare in the existing technology, and there is little reference in the existing technology. A large winch is required to adjust the amplitude of the rocker arm so that the tower is installed in place, and the number of hoistings is high, the amount of high-altitude work is large, unsafe, and the stability of the hoisting system is difficult to guarantee. Compared with ultra-high voltage line towers, UHV towers increase in weight and vertical height, and changes in the size and shape of tower windows will inevitably lead to increased weight and length of hanging parts, and the hoisting position is far away from the center of the tower. Selecting a pole with an appropriate length and lifting weight can meet the requirements of greater hoisting weight and lon...
