Abstract

The invention relates to electrical engineering and can be used for laying cables in electrical substations and industrial plants. The goal is to increase the cable capacity while reducing material consumption. The device contains rigidly longitudinal elements 2 fixed on supports and a zigzag-like continuous element 3 in the form of a flexible thread connected to them, forming cross-beams 4 for laying cables 5. Making cross-beams in the form of a flexible thread changes the nature of the stressed state, since flexible threads work tensile and rigid bending. This leads to a more complete use of the material of the cross-pieces, which makes it possible to reduce their cross-section and, consequently, reduce the metal consumption of the device 1 Cp f-ly, IIil. i (/)

The invention relates to electrical engineering and can be used for laying cables at electrical substations and industrial plants.

The purpose of the invention is to increase the cable capacity while simultaneously reducing material consumption by changing the nature of the stress state in the device.

A cable laying device containing rigid longitudinal elements 2 fixed on supports 1 and zigzag-shaped connected with them zigzag like 11 continuous element 3 forming cross-beams 4 for laying cables 5, Zig-zag element 3 is formed by a flexible thread made of wire or non-metallic material, nprnmer layer. (assy. The fastening of the longitudinal elements 2 on the supports 1 is rigid. The supports 1 consist of shelves 6 and racks 7 and are fixed above the ground. The shelves 6 function as rigid connections between the longitudinal by the elements 2. On their side of the longitudinal elements 2 along their height there are stops 8 connected to them in the upper part and to the shelves 6. If necessary, to increase the overall stability of the longitudinal elements 2 under them establish additional rigid connections 9 and stops 8. Zigzag-like element 3 mounted on the longitudinal elements 2 with the help of housings 10 arranged on them. Depending on the location of the hooks 10, as well as on the manufacturing technology, various embodiments of a continuous zigzag element are possible, in particular, elements 11 and 12.

When laying cables on the ground surface, the supports are made of reinforced concrete bars 13 laid on the ground surface. On bars 13 longitudinal elements 2 are installed, on which metal covers 14 are laid. Hard connections 9 and lateral stops 8 are installed in a similar way. The connection of the lugs 8 with the bars 13 is carried out by welding the lugs 8 to the embedded parts 15.

Possible device option for

cable laying on the surface

3eNLnn, in which the longitudinal elements are made of reinforced concrete bars 16, laid on the transverse bars 13 o. The supports 8 are welded to the mortgage parts 15 and 17 in bars 13 and 16. Installation of additional cross-links is not required here. The longitudinal element 16 has a reinforcement cage including longitudinal

18 and transverse 19 and 20 rods. The transverse rods 20 are provided with outlets 21, serving to fasten the zigzag element 12. At bars 16, a cover 22 is laid, made, for example, of asbestos cement.

In the proposed device, the weight of the cables 5 is applied to the flexible transverse elements 4 and causes tensile forces in them, which are transmitted to the longitudinal elements 2 or 16. An increase in the cable capacity of the device causes an increase in these efforts, which, together with vertical loads, can lead to a loss of overall stability longitudinal elements. Increased stability is achieved by rigidly fixing the longitudinal elements.

on supports. If it is necessary to further increase the stability of the use of tats, additional rigid cross-links and side stops.

The use of flexible elements instead of rigid crossbars for laying cables changes the nature of the stress state in the cross pieces, since flexible elements work on stretching, and rigid elements bend. This will lead to more complete use.

the material of the crossbars, which makes it possible to reduce their cross section and, consequently, reduce the metal consumption of the device.
