Problems solved by technology

[0005] In view of the above problems, the present invention provides a device and method for integrally assembling iron towers of overhead transmission lines. It is aimed at iron towers whose tower height is not very high, such as 12-30 meters. Drum type and other similar tower types, to solve the requirements that the overall assembly and disassembly assembly of the iron tower cannot take into account the construction efficiency, construction quality, and reduce high-altitude operations at the same time

Embodiment 1

[0062] Such as Figure 1-7 , a kind of overall assembly device for overhead transmission line iron tower fragmentation, which includes a long steel pipe 1, the first short steel pipe 2 and the second short steel pipe 3 are obliquely welded on the two side walls of the long steel pipe 1 respectively, and the long steel pipe 1 1. After the first short steel pipe 2 and the second short steel pipe 3 are welded, an X-shaped rigidity enhancement device 12 is formed, and the four ends of the X-shaped rigidity enhancement device 12 are welded with threaded joints 6, and the other end of the threaded joint 6 is processed There is a threaded column, and the threaded column and the threaded sleeve of the connecting sleeve 7 form a threaded connection. The connecting sleeve 7 adopts a double-ended threaded sleeve, and the other end is connected with a steel pipe 8 through threaded fitting to extend the X-shaped The length of the rigidity enhancing device 12.

[0063] Further, the first s...

Embodiment 2

[0072] Such as Figure 1-18 , The present invention provides a method capable of integrally assembling iron towers of overhead power transmission lines in pieces, and the method includes four parts: pre-construction preparation, arrangement of tools, erection of iron towers, and dismantling of tools.

[0073] The preparation steps before construction are as follows:

[0074] (1) Transport tower materials and construction tools to the construction site;

[0075] (2) Splice the "X" type joints delivered to the site with the standard joints through the threaded joint 6 and the connecting sleeve 7 to make an X-shaped stiffness enhancement device 12, and determine the connection according to the length of the required X-type stiffness enhancement device 12 The number of standard joints requires splicing two sets of X-shaped stiffness enhancement devices 12;

[0076] (3) Assemble the whole piece of tower material 9, 10 at a suitable position;

[0077] (4) Assemble side tower mate...

Abstract

The invention relates to an integral piece-assembling device and method for an overhead transmission line iron tower. The integral piece-assembling device comprises long steel pipes. A first short steel pipe and a second short steel pipe are obliquely welded to the two side walls of each long steel pipe; the long steel pipes, the first short steel pipes and the second short steel pipes are welded to form X-shaped rigidity strengthening devices; and thread joints are welded to the four tail ends of each X-shaped rigidity strengthening device correspondingly; a thread column is machined at the other end of each thread joint; the thread columns and thread sleeves of connecting sleeving tubes are in threaded connection; and the connecting sleeving tubes adopt double-head thread sleeving tubes, and the other ends of the connecting sleeving tubes are connected with steel pipes in a threaded matching mode to prolong the lengths of the X-shaped rigidity strengthening devices. The integral piece-assembling device aims at the tower not very high, such as the tower with the height being 12-30 m, and the tower shape is similar to the shape like a Chinese character ''shang'', the shape like a Chinese character ''gan'', the drum shape and the like. The problem that integral assembling and decomposition assembling of the iron tower cannot simultaneously take account of the requirements of construction efficiency, construction quality and aerial working reducing is solved.

Description

technical field [0001] The invention belongs to the technical field of iron tower construction, and in particular relates to a construction device and method for the integral assembly of iron towers in the form of fonts, dry fonts, drums and other similar tower-shaped towers on overhead transmission lines, which are used to reduce high-altitude operations, improve construction efficiency and Construction Quality. Background technique [0002] The iron tower is an important supporting part of the overhead transmission line, and its construction quality and construction efficiency have an important impact on the quality and construction period of the entire transmission line. At present, the construction methods of transmission line tower assembly mainly fall into two categories: decomposed assembly and overall assembly. The decomposed assembly is further divided into disassembled assembly towers with inner cable suspension holding poles, external cable suspension holding pole...
