Abstract

This invention relates to electrical engineering, in particular to flexible current leads. The goal is to increase reliability and simplify the design while expanding operational capabilities. The device contains parallel flexible tapes 1 and 2, between which the energy carrier 3 is placed. The tapes 1 and 2 are interconnected by means of a flexible elastic element 10 passed through holes in the bends of the tapes. To enforce restriction of the vertical dimension of the loop, the plane 7 was used. Such an implementation allows laying energy carriers on a section with a complex profile, as well as increasing reliability as a result of ensuring a constant bending radius of the loop. 1 hp f-ly, 4 ill.

Description

The invention relates to electrical engineering, in particular, to devices for powering mobile consumers.

The purpose of the invention is to improve the reliability and simplify the design while expanding the operational capabilities,

FIG. 1 shows the device, a general view; in fig. 2 — node I in FIG. one; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - scheme.

A device for transmitting electrical energy from a stationary object to a mobile one contains a carrier device, made in the form of two parallel flexible elastic bands 1 and 2, between which the energy carrier 3 is placed along the entire length, one end fixed on the stationary 4, and the movable 5 object moving along the suspension paths 6, and the device for the forced formation of a loop 7, In each of the flexible elastic bands 1 and 2 along the longitudinal edges, the limbs 8 with a hole 9 are made, which are cross constraints. Each of the bends 8 is perpendicular to the plane of the flexible elastic tape and its longitudinal edges, and the center of the hole in it is located in the longitudinal symmetric plane (in the neutral plane) of the bearing device, the plane of each limb 8 is parallel to the longitudinal edges of the flexible elastic tape. Flexible elastic tapes 1 and 2 are connected along the length by means of a long flexible elastic element 10, passed through the holes in the limb 8 and embedded at the ends in the form of a flat spiral 11.

The energy carrier 3 is located freely between the flexible elastic elements 1 and 2 and the bends 8 (transverse limiters) and is fixed in front of the leads to the stationary object 4 and the movable 5 on the flexible elastic band 1 by means of the clamps 12. Between the edges and the bend plane 8, the size 1, which excludes contact of the energy carrier 3 with the edges of the limb 8, i.e. excludes damage. Flexible elastic ribbons 1 and 2 together with energy carrier 3 are laid in two branches: fixed 13 and movable 14 and form a loop 15 of radius R, equal to

dimensional minimum permissible radius of the bend of the energy carrier 3. The fixed branch 13 is laid on the base 16, and the transverse edges of the flexible elastic bands 1 and 2 are rigidly fixed on the bracket 17 of the base 16. The transverse edges of the flexible elastic bands 1 and 2 of the moving branch 14 are fixed on the bracket 18 of the moving object 5. The loop 15 is enclosed between the device for forming the loop 7 and the base 16. The flexible elastic bands 1 and 2 are arranged so that between the bends 8 a step t is maintained, at which their mutual contact in the loop 15 section is eliminated avoid their deformation.

The device works as follows.

When moving the movable object 5, the branch 14 moves with it, shortening or lengthening (depending on the direction of movement) - and pushes or drags the loop 15 respectively. When the movable branch 14 is extended, under the action of its own weight G, it forms an acceptable natural deflection f, the maximum value of which is limited by the size L. The cross section of flexible elastic bands 1 and 2 is chosen so that, with a maximum weight G of the moving branch 14 (at its maximum length), the bending stress in the flexible, elastic bands 1 and 2 in the loop section 1 5 less than yield stress. This means that the radius R of the bend of the loop 15 remains constant. The base 16 is laid parallel to the movable track 6, and the device for the forced formation of a loop 7 is designed as a plane, laid parallel to the base 16 and is located above it at a distance L defined by the radius R of the loop 15.
