Problems solved by technology

However, as the erection and equipment method of the infrastructure iron tower of the high-voltage transmission line, the methods usually adopted so far mainly include: 1. Pulling the external pole tower: mainly assembling small iron towers, because the external pole is short and small , Light, large and medium-sized towers are wide, large and heavy, so it is not suitable for erecting large and medium-sized special towers; The pickling pole is inside the tower, and it can only be hoisted in a single segment and added to the two sides in bulk, so the speed is slow, the high-altitude pickling pole is heavy, difficult to control, and difficult to transport in transition; For iron towers, 12 steel ropes need to be pulled up and held down by the middle hoop to fix the poles in the tower. The poles need to be raised once for each hoisting section. The coordination and coordination of 12 steel ropes are required to raise the poles, which is ...

Embodiment 1

[0049] Two light-duty aluminum alloy poles are used, and the top is connected with a steel rope as a sealing rope. On the outside of the two poles, four steel ropes are used to hold the pole at 30 degrees and the ground at less than 60 degrees. The ground anchor pile is fixed on the wire, and then a double-drum motorized winch mill is used to lift the vertical tower with two sets of wire ropes.

[0050] Such as figure 1 As shown, taking the hoisting of the whole section of the small tower as an example, first, the bottom section of the tower is bulked on the ground according to the traditional method, and then the two poles are erected on the second main material of the bottom section of the tower, and the top of the two poles is connected with a sealing rope. And two temporary stay wires are fixed on the ground anchor pile wires respectively, and the motorized winch is fixed in an appropriate position. The two pulleys are respectively installed at the bottom of the main mater...

Embodiment 2

[0054] Such as Figure 7 to Figure 13 As shown, take the example of a single twisting mill and single pole with 4 landings and 8 branch pulls inside and outside, high point lifting and low point positioning, and changing to a large vertical tower. Such as Figure 1 to Figure 7 As shown, lifting the small tower: still use the original method of pulling the pole outside. Hoisting of medium-sized towers: In the bottom section, a single pole is placed in the ABCD four foundations of the tower, and the 4 external pulls are generally two along the line and two vertical lines, and the anchor piles are fixed at less than 60 degrees to the ground. According to the hoisting load capacity of the tools and equipment, hoist the two large sides in sections and complete the two sides in bulk, (or a whole section in bulk on the ground) lift the pole on the inner side of the D foot with spikes, tilt slightly to the A side, and lift it up in sections After the second segment, use the 4 upper ...

Abstract

The invention discloses a method for assembling an iron tower through high-voltage power transmission lines. The method resolves the problems that when existing large and medium iron towers are erected and installed, many tools and workers are needed, the occupied space is large, it is troublesome to transfer the large and medium iron towers to another site, the construction procedures are complex, the construction speed is low, and the safety coefficient is low. The method is characterized in that tools such as light aluminum alloy derrick masts, traction steel ropes and a winch grinder are adopted, and large, medium and small special-shaped high-voltage power transmission line iron towers are assembled through the methods that four branches are on floor and eight branches are pulled, high points are hoisted and low points are in place, a large surface is used for hoisting, and derrick masts are arranged inside and outside. The method has the advantages of being wide in application range, needing a few tools and constructors, convenient and rapid to transfer to another site, safe and efficient to install and the like, and can be widely used for assembling various large, medium and small special-shaped iron towers.

Description

1. Technical field [0001] The invention belongs to the construction of electric power infrastructure, and in particular relates to a method for assembling high-voltage transmission line iron towers of various specifications by using existing basic tools such as poles, twisting mills, steel ropes, ground drills, corner piles, and pulleys. 2. Background technology [0002] As a scientifically developed clean energy, electricity is constantly reforming, innovating, accelerating, consolidating, and improving with the rapid development of society. In order to meet the needs of the rapid development of social sciences, hard-working electric workers have built tens of thousands of high-voltage transmission line iron towers to transmit electric energy for thousands of high-voltage lines and stand proudly on the land of the motherland, sending electricity to every corner of the motherland. Let people live a happy, joyful and healthy life. However, as the erection and equipment metho...
