Abstract

The invention provides a basic guide rail for a helicopter assembly transmission line iron tower leg section, which comprises a guide plate, a guide plate rib plate, a hoop and a small rib plate, wherein the guide plate rib plate is arranged under the guide plate; the hoop is arranged at the lower end of the guide plate rib plate; and the small rib plate is arranged between the guide plate rib plate and the hoop. The guide plate provides guiding function for hoisting and positioning a tower leg section by a helicopter; the guide plate rib plate provides support for the guide plate and transmits the impact force of the hoisted tower leg section stressed by the guide plate to the hoop; the hoop is used for connecting the guide rail and a tower leg base; and the small rib plate can improve the local impact resistance of the guide rail. The basic guide rail has the advantages of simple structure, convenience of manufacture, load transmission without connecting piece with the tower leg base, installation of the basic guide rail without modification of the tower leg base, use for helicopter assembly for various self-supporting iron tower leg sections, high universality and wide application range.

Description

technical field [0001] The invention belongs to the field of construction equipment for erecting iron towers of overhead transmission lines, and in particular relates to a basic guide rail for erecting the leg sections of iron towers of electric transmission lines by helicopters. Background technique [0002] According to the structural form, size, weight and terrain conditions of the transmission line iron tower, there are generally two construction methods for its hoisting and assembly, that is, the overall tower method and the disassembled tower method. The integral tower method refers to a construction method in which the iron tower is pulled up into place by using poles, cranes and other equipment after the iron tower is laid flat on the ground and assembled. This method is generally suitable for simple structure and light weight cable towers At the same time, a certain range of flat sites is required for assembly and tower erection. The method of decomposing and assem...
