Abstract

The utility model relates to the electric power industry, in particular, to the device of a rack made of bent profile for supports of overhead power transmission lines of 6-10 kV. The technical result of the proposed utility model is to increase strength, rigidity, and manufacturability. The technical result is achieved by the fact that the support of the power line support, comprising a housing of two segments, each of which is curved from sheet steel in the form of half the side surface of a multifaceted pyramid, two opposite faces of which are formed by two pairs of side faces lying in the same plane ( extreme segments), the body segments are rigidly interconnected at a distance between the said pairs of extreme sections lying in the same plane using a set of straight lines GOVERNMENTAL elements, each welded to opposite sides of the opposed lateral faces forming the lattice, characterized in that the rack is in the form piramidy.Vosmigrannaya octagonal pyramid can be formed and neravnougolnoy scalene. The width of the front face of the octagonal pyramid (a) can be greater than the width of the diagonal (b) and side faces (c), and the angle between the front and diagonal face (α) is larger than the angle between the diagonal and side face (β): a> b, a> c, α> β. The lattice connecting the parts from the metal profile can be made with parallel straight steel elements made of sheet or shaped (corner, channel, circle) rolled. The lattice connecting the parts of the metal profile can be made with straight steel elements located at an angle to each other (diagonal lattice). The specified implementation will allow to limit access to the top of the support due to the inconvenience of climbing on inclined elements.

Description

The utility model relates to the field of electrical equipment, and specifically to a kit for intermediate support overhead power lines.

The well-known "KIT FOR INTERMEDIATE SUPPORT OF THE AIRLINE OF ELECTRIC TRANSMISSIONS" RU PM 85182 [2], containing a stand made in the form of a hollow pyramid from sheet material, and the stand is made in the form of an octagonal pyramid.

The disadvantage of this device is the increased consumption of materials due to the continuous housing.

The closest technical solution is “RAILWAY CONTACT NETWORK SUPPORT RACK” RU PM 144974 [1], comprising a housing of two segments, each of which is curved from sheet steel in the form of half of the side surface of a polyhedral pyramid, two opposite sides of which are formed oriented towards each other with two pairs of side walls lying in the same plane, the body segments are rigidly connected to each other at a distance between the said pairs of extreme sections lying in the same plane using a set of straight steel elements, each of which are welded with opposite sides to the opposite side walls forming a lattice, the rack is made in the form of an octagonal pyramid, the octagonal pyramid is made unequal and unequal, the angle between the front and diagonal faces is greater than the angle between the diagonal and side faces.

The device has a reduced metal consumption compared to [2] due to the presence of direct steel elements that make up the two faces of the pyramid.

The disadvantage is reduced strength and stiffness with respect to efforts directed along the frontal face. The disadvantage of this device is the low adaptability, due to the need to produce faces that are remote from the edges of the segments.

The technical result of the proposed utility model is to increase strength, rigidity, manufacturability.

The technical result is achieved by the fact that the power transmission tower support, comprising a housing of two segments, each of which is bent from sheet steel in the form of half the side surface of a multifaceted pyramid, two opposite faces of which are formed by two pairs of side walls lying in the same plane ( extreme segments), the body segments are rigidly interconnected at a distance between the said pairs of extreme sections lying in the same plane using a set of straight lines elements, each of which are welded with opposite sides to the opposite side walls forming the lattice, the rack is made in the form of an octagonal pyramid, the octagonal pyramid is made unequal and unequal, the angle between the front and diagonal faces is greater than the angle between the diagonal and side faces, characterized in that the width of the front edge the octagonal pyramid is larger than the width of the diagonal and lateral faces.

The lattice connecting the parts from the metal profile can be made with parallel straight steel elements made of sheet or shaped (corner, channel, circle) rolled. The specified implementation will achieve savings in material elements.

The lattice connecting the parts of the metal profile can be made with straight steel elements located at an angle to each other (diagonal lattice). The specified implementation will limit access to the top of the support due to the inconvenience of climbing on inclined elements. The lattice formed by straight steel elements can be combined, for example, the lower elements are diagonal at an angle to the segments, and the upper elements (or element) are horizontal, depending on the strength requirements of the support and other requirements.

The rack is shown in FIG. 1 (total water) and in FIG. 2 (section), where:

1 - segments;

2 - side walls;

3 - frontal face;

4 - diagonal face;

5 - connecting elements;

6 - the angle between the frontal and diagonal faces;

7 - the angle between the diagonal and side faces.

The device operates as follows: The support consists of two segments 1, on the edges of which side walls 2 parallel to each other are formed and which are connected by connecting elements 5 welded to them. Diagonal faces 4 are adjacent to the side walls 2, the front face 3 is located in the middle of the segment. The angle between the frontal and diagonal faces 6 is greater than the angle between the diagonal and lateral faces 7.

EFFECT: increased strength and stiffness is achieved by a large value of the stiffness coefficient for the plate

frontal face with a wider width. EFFECT: obtaining manufacturability is achieved by shifting roll forming operations to the edge of the segment, which will simplify roll forming equipment.

Industrial application. The utility model can be successfully used for the manufacture of power transmission towers.
