Method for assembling iron tower through high-voltage power transmission lines

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...

AI Technical Summary

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 difficult to control. The poles in the tower can only be single Fragment hoisting plus bulk two sides, the construction speed is too slow and requires a lot of people; 4. Bulk crane tower: large, medium and small towers can be assembled, but the construction speed is too slow, the work at height is difficult, the labor intensity is too high, and it is difficult to meet the construction requirements. Node requirements; 5. Internally suspended rotary pole and internally suspended small tower hoisting tower: mainly hoisting the cross-river tower, which requires too many tools, equipment, and personnel, and the operation of equipment erection is difficult, the construction speed is slow, and the cost is high; 6. Crane Helicopter tower: This is a method used in two extreme cases, one is very convenient for transportation and the other is very inconvenient; 7. The original integral tower is inverted: this method has been eliminated and not adopted
