WITH

The invention relates to the construction of high-voltage power line poles in hard-to-reach areas with difficult ground conditions,

The aim of the invention is to reduce the material consumption of the support.

FIG. 1 shows the power line support, common Hades (about axometry); in fig. 2 - the same, view in the plane of the traverse; in fig. 3 - the same. view in the plane of the line.

The power line support includes two X-shaped connected racks 1, made D in the form of flat lattice trusses, with outer 2 and inner 3 by themselves. Racks 1 are installed on foundations 4, are interconnected by means of a cylindrical hinge 5 and are combined by a rigid horizontal lattice beam.

b below the node from the conjugation. Outside along the horizontal beam b are placed in one plane with the racks 1 themselves. The brace 7 is made in the form of a triangular truss with themselves, which at the bottom is attached to the foundation 4 by means of the hinge 8, and at the top by means of the hinges 9 at the point of attachment to the uprights 1. Traverse 10 is made flexible of wires of insulators 11, Flexible connections 12 connecting the top of each rack 1 with the base of the adjacent stand are provided with tensioning devices 13 (for example, lanyards). The upper ends of the uprights 1 are connected by a flexible thrust 14, and the intersection point of the uprights 1 is connected to the support assembly of the strut 7 on the Foundation 4 by a flexible link 15 to the tensioning device 16.

For me, the ends of the uprights 1 and the strut 7 are connected by flexible couplings 17 with tensioning devices 10, and the upper ends of the uprights 1 dll of the ground wire suspension are provided with rigid cantilever elements 19 arranged in the plane of the uprights 1,

Flexible links 17, 12, 15, which unite the bases of the uprights, the top of each rack with the base of the adjacent stand, and the node of the intersection of the stands with the base of the brace are made of steel cable and are equipped with tensioning devices, such as lanyard, with the help of which It is tentative,

Two intersecting pillars 1, joined by a beam G), flexible cross member 10, flexible tight 14, flexible connections 12, and one backbone 17, form a fairly rigid flat working face of the support.

During operation under the influence of loads in racks 1 of the support, longitudinal and transverse forces and bending moments arise, which lead to the appearance of longitudinal forces in the stack and the grid of racks.

The forces from the vertical load along the internal racks themselves are partially transmitted to the attachment points to them on the platform 7 and load them, resulting in the effect of the solution forces, which are perceived by flexible links 17. The forces from horizontal loads (wind loads perpendicular to the VL axles) are perceived by the elements of the X-shaped face of the sleepers on the samye racks 1 and beams 6, the flexible connections 12, the flexible tie 14 and the flexible connection 17), which causes 5 to form a rigid

core construction with elements that work only for tension - compression. These factors can reduce the material intensity of support elements (racks, beams, strut), as well as reduce the number of flexible connections, which will significantly reduce its cost, reduce labor intensity and increase power transmission lines on hard-to-reach roads with heavy ground conditions. A Kok support, which is a rigid spatial structure, can be assembled at the test site, with the help of helicopters, in working form, together with the foundations, can be transported to the road. Claims of the Power Line Support, including X-shaped connected racks, mounted on a foundation and joined by a rigid horizontal beam below their intersection node, attached to the beam brace, traverse, flexible connections, connecting the bases of the racks, the top of each rack with the base of the adjacent rack and the intersection of the posts with the base of the strut, and the insulation of the insulators, which, in order to reduce the consumption of materials, the strut, the strut and the horizontal beam are made of lattice, and the internal beams are placed in one plane with the racks themselves, and the internal beams above the beams are placed vertically, with the racks connected at the intersection hinge, and the strut is made in the form of a triangular truss hinged to the ends of the horizontal beam and to the foundation, and the upper the ends of the racks are combined by flexible pull.
