Background technique

With the increase of power supply load and the gradual increase of substations, the task of erecting transmission lines is getting heavier and heavier. In daily practical work, it is found that when assembling the 35-110kV iron tower, due to the small size of the tower, the construction basically adopts the method of directly pulling the tower material by manpower, which has certain potential safety hazards and requires a lot of time and manpower. If the pole tower is assembled with internal suspension holding poles, the poles themselves are heavy and the assembly is more complicated, which is not suitable for erecting small towers. According to statistics, Yiling District needs to erect more than 200 bases of 35-110kV iron towers every year due to various reasons such as overhaul, technical renovation, overhaul, and rush repair. Every construction task is accompanied by safety risks. It is imminent to change the traditional tools for erecting iron towers.

There are two commonly used methods at present:

Method 1: The construction personnel directly pull up the main material of the first iron tower, fix it and use it as a pole, and then lift other main materials and inclined materials.

The disadvantages of this method are: (1) when lifting the main material of the iron tower, the personnel stand on the top of the platform, and the safety belt is hung low and high, which has potential safety hazards; The main material has no anti-fall measures; (3) When assembling the main material, the screw holes are aligned manually, which is time-consuming and labor-intensive.

Method 2: Assemble the inner suspension pole inside the iron tower, and then use the winch to lift the tower material for assembly.

The disadvantages of this method are: (1) The assembly and disassembly of the inner suspension pole is complicated, and there are many ground coordinators; (2) The inner suspension pole is mostly used to assemble large iron towers, and the iron tower below 110kV is overkill; (3) The inner suspension pole higher cost.
