Description

Technical Field

[0001] The invention relates to the technical field of electric power facilities, and in particular to a load-bearing iron component structure for a tower body of an electric power tower. Background Art

[0002] Power towers are transmission line towers, which are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. The entire tower is composed of angle steel, connecting steel plates and bolts. Individual components such as tower feet are welded from several steel plates into an assembly. The structure of the power tower is generally divided into tower head, tower leg and tower body. The use of such a spatial truss structure design can effectively disperse and bear loads from all directions. The connection between its various parts mainly adopts rough bolt connection, which is simple and reliable and can withstand shear force; the tower head is the part where the cross-section of the tower changes sharply from the tower leg to the top. If there is no sharp change in the cross-section, the part above the lower chord of the lower cross arm is the tower head; the tower leg is the first section of the tower above the foundation; and the tower body is the part between the tower leg and the tower head. The load-bearing iron structure of the tower body of the power tower is a vital component of the power transmission system. It is directly related to the safety and stability of the power line. Therefore, the load-bearing iron structure of the tower body of the power tower is an important guarantee for ensuring the safe operation of the power line because of its durability, easy installation and maintenance, etc.

[0003] The parts that make up the tower structure can be divided into main materials, diagonal materials, horizontal materials, auxiliary materials and the bolt fastener structure that connects them; the main materials are the angle steels that bear the main force of the tower and the materials that constitute the main frame of the tower, the diagonal materials are the cross materials that connect the two main materials, and the horizontal materials are the horizontal materials that connect the two main materials. The auxiliary materials are the angle steel materials other than the main materials, diagonal materials and horizontal materials.

[0004] The load-bearing main iron member of the tower structure is the main material structure, that is, the main frame structure of the tower body, which directly acts on the load-bearing hand force of the tower body. The load-bearing main iron member of the tower body is generally a single equilateral right-angle steel. Bolt assembly holes for connecting angle steels are opened near the ends of the load-bearing main iron member, and then the angle steels are fixed with bolts through the assembly holes at the ends, so as to realize the connection between the main materials and the main materials, as well as the connection between the main materials and the oblique materials and the cross materials. Assembly holes are often opened in the middle of the load-bearing main iron member to provide angle steels for assembly of the main materials and the oblique materials. The assembly holes opened at the ends and the middle of the load-bearing main iron member must be distributed along the same center line (the center line of the hole), and the center line distance (the distance between the back of the angle steel and the center line of the hole) is generally half of the width of the load-bearing main iron member to ensure uniform force load.

[0005] At present, the main load-bearing material of the tower body of the power tower adopts right-angle steel iron components as the frame load-bearing structure, which needs to be reinforced by setting a plurality of horizontal cross members and obliquely installed diagonal members. However, its own load-bearing quality is poor, and its deformation resistance and tensile strength are also poor, which is not conducive to ensuring its own structural stability under the working conditions of increased load-bearing and strong wind weather conditions; and because the iron components of the main load-bearing materials of the tower body are connected to other main materials or diagonal and horizontal materials through angle steels, the connection and assembly points are basically side walls, which makes it difficult to assemble and fix from the ends of the angle steels, which is not conducive to enhancing the load-bearing quality and structural strength of the connection parts.

[0059] Working principle:

[0060] When assembling the entire tower body load-bearing main iron member 1, the first angle steel assembly through hole 2 at the end of the tower body load-bearing main iron member 1 is installed with the angle steel fixed to other main materials and horizontal and oblique iron members. When assembling the conventional two side walls, the end of the angle steel is pressed against the first angle steel end assembly frame 5. By assembling the end face of the angle steel with the first angle steel end assembly frame 5, if the end face against which the angle steel is pressed is through and lacks an end sheet structure, the end face of the angle steel can be welded with a pre-punched hole. The iron sheet component can also increase the installation points from the end face of the angle steel; similarly, when assembling the angle steel connecting the horizontal material and the oblique material at the second angle steel assembly through hole 3 in the middle of the tower body load-bearing main iron component 1, the angle steel is also abutted against the end face of the second angle steel end assembly plate frame 10 to assemble and fix the end face structure. If the angle steel lacks an end face fixing structure, the above-mentioned welding operation of the additional end plate structure of the angle steel connected to the first angle steel assembly through hole 2 is repeated, thereby realizing the assembly operation of increasing the connection structure points.
