Problems solved by technology

[0003] In the prior art, raising transmission line towers is often achieved by means of trusses. Because the trusses mainly bear tension or pressure, they can make full use of the strength of the material, thereby ensuring the firmness of the entire transmission line towers after being raised, but there are the following problems: The connection between the truss and the transmission line tower and tower foundation is a weak point, the connection position is easy to loose, and the connection position is also a corrosion weak point

Embodiment 1

[0024] The truss used for raising the transmission line tower described in this embodiment includes four base columns in an I-shaped structure and a connecting column connecting the four base columns, and the base columns and the connecting columns are coated with antirust paint. The base column includes a column 1, a bottom platform 3 at the bottom of the column 1 for connecting the foundation of the tower, and a top platform 2 at the top of the column 1 for fixing the supporting legs of the tower; the bottom platform 3, the top platform 2 and column 1 are an integral structure, the top platform 2 is surrounded by an outer guard plate 203 higher than the top surface of the top platform 2, the edge of the outer guard plate 203 is provided with an inner buckle edge, and the top surface of the top platform 2 is provided with a The platform 2 is a long stud 202 coated with anti-rust paint on the surface of an integral structure, and a permeable hole 201 is provided at the intersec...

Embodiment 2

[0029] This embodiment is the same as Embodiment 1 except the following features:

[0030] The antirust coating comprises the following raw material components in parts by weight: 10 parts of epoxy resin, 20 parts of N-methylpyrrolidone, 45 parts of polyether polyol (molecular weight is 4000, hydroxyl value 430mgKOH / g), isofor 15 parts of ketone diisocyanate, 7 parts of trimethylolpropane, 2 parts of ethylenediamine, and 3 parts of triethylamine.

Abstract

The invention discloses a truss for raising a power transmission line tower, and relates to the technical field of power towers. The problems of the connection firmness and corrosion of a raised structure and a tower when the tower needs to be raised in the prior art are solved. The truss comprises four foundation columns and connecting columns connected with the four foundation columns. Each foundation column comprises a stand column, a bottom table located at the bottom of the corresponding stand column and used for being connected with a tower base and a top table located at the top of thestand column and used for fixing a tower supporting leg. Each bottom table, the corresponding top table and the corresponding stand column are of an integrated structure. Outer guard plates which arehigher than the top surfaces of the top tables are arranged at the periphery of each top table. An inner buckling edge is arranged on the edge of each outer guard plate. A long stud which is in an integrated structure with the corresponding top table is arranged on the top surface of the top table. The truss is coated with antirust paint. The truss is used for raising the power transmission line tower and can solve the problems of the firmness and corrosion of the tower after being raised.

Description

technical field [0001] The invention relates to the technical field of power poles and towers, in particular to a truss for raising power transmission line poles and towers. Background technique [0002] With the development of infrastructure, when the buildings, structures, and roads in many cities and towns are raised, the distance between the transmission line and these buildings, structures, and roads will be reduced, resulting in insufficient safety distance and potential safety hazards. Re-erection of transmission line towers, firstly, the land resources are tight, and the erection environment is complicated; secondly, the number of re-erected towers is large, the distribution is wide, the erection is difficult and the cost is high; . Therefore, the way to solve this type of problem in the prior art is to raise the transmission line tower. [0003] In the prior art, raising transmission line towers is often achieved by means of trusses. Because the trusses mainly bea...
