22 2 The invention relates to electrical engineering and can be used as a device for the continuous transmission of electricity from a fixed object to a mobile, for example, to a transformer means. A device for supplying energy from a stationary object to a movable one is known, comprising a chain with articulated but installed links, inside of which are cables connected by one end to a stationary object and others to a movable one, which guides the working section and the storage section guides. The hinge chain is connected to carriages moving along the guides of the work area. Some carriages are made with additional rollers to move along the guides of the storage area. In the hinge chain, flexible energy carriers are located associated with a moving object and a power supply point. At the border of the plots, the guideline is mounted. The guides of the storage area are located between the guides. When the moving object is moved, the carriages rollers, bypassing the guide roller, fall on the guides of the working area. When moving the Moving Object towards the storage area of the carriage roller on the border of the sections, they move away from the guides of the working section, while the links of the hinge chain and the carriage form loops under the action of gravity. Some carriages are made with additional rollers, which at the boundary of the sections fall onto the guides of the storage area. Carriages with additional rollers support loops, chains in the storage area of the Gp. The disadvantage of this device is that the cable undergoes numerous alternating bends during operation, and in the storage area the cable is laid with a lot of bends, which degrades its mechanical and electrical characteristics. about the process of operation. In addition, this device design requires an increase in the storage area in height and does not allow servicing the working area up to several tens of meters. i 2 The closest in technical essence to the invention is a device for supplying electric power from a stationary source to a mobile consumer located at different ends, containing a circuit with hinged links, inside which are located cables carrying rollers cantilevered with variable pitch along the sides of the chain, the upper branch of which is placed on the guides with notches for the passage of the carrying rollers, and the lower on the fixed base 2J. The guides and base are horizontal. The cutouts in the guides are designed in such a way that all bearing rollers cannot be simultaneously above them. Cables are not subject to numerous bends. In the device, the chain is laid in the interlocking area in two branches. If it is necessary to evacuate the device from the working area, the service area may be twice as long as the storage area. The task of increasing the service area more than twice the known device does not solve. The purpose of the invention is to increase the service area with limited dimensions of the storage area. The goal is achieved by the fact that a device for supplying electric power from a stationary source to a mobile consumer, located at different levels, contains a curved chain with hingedly connected links, inside of which are located cables carrying a roller, attached only in alternating pitch on the sides the chain, the upper branch of which is placed on guides with cutouts for transition of the rollers, and the lower one - on the fixed base, is provided with a tray fixed to the mobile consumer, parallel to the base, below the level of the guide, l-shaped guide lugs are installed at the end of the tray and the base; the chain is made with two outlets of different radius with the formation of a middle branch, the latter being laid on the tray. FIG. 1 and 2 show the device in the storage area, general view; in fig. 3 is a view A of FIG. one; in fig. node I in FIG. one; on

FIG. 5 is a diagram of laying the chain in the working area and the storage area; in fig. 6 is a section BB in FIG. one.

The device contains a hinge chain 1, in which the cables are located. 2, one end connected to a fixed source 3, and the other to a moving object:, moveable along the suspended path m 5

The hinge chain 1 is made from to. 6 links connected to each other on the hinges. 7.. .

Each half of the hinge chain 1 is made up of links that have a different bevel angle of the end / and. To ensure that the hinge chain 1 is laid in the storage area 8 in a spiral in three horizontal branches. The lower branch 9 is laid on the base 10 mounted on a stationary object 3, at one end of which the first link 11 of the hinge chain 1 is rigidly fixed and the power supply device 12 is installed, and at the other end is an equal L-shaped ledge made in the form of a bracket 13, spanning chain 1 to limit the bending motion of the hinge chain 1. The middle branch 15 is laid on a tray 1b fixed on a movable object t parallel to the base 10. On one end of which is rigidly fixed on: the last link 17 of the hinge chain 1 and the power supply receiver 18 is mounted, and on the other end is a guide protrusion made in in the form of a bracket 19 covering the hinge chain 1 to limit the movement of the bend 20 of the hinge chain 1.

The upper branch 21 is located on the storage rails 22 of the storage section 8 using rollers 23 mounted cantileverly on the sides of the hinge chain 1 and having a spherical end surface to prevent sticking as the hinge chain 1 moves, guides 22 of the storage section 8 and 2 working sections 25, along which the rollers 23 roll over, have a channel-like shape to limit the vertical movement of the rollers 23. To ensure the movement of the hinge chain 1 in the storage area 8 in the guide rails 22 The storage box 8 is provided with openings 26. The entry portions of the edges of the opening 26 are rounded to allow movement of the rollers 23 of the hinge chain 1 without hardening 4

Denmark if it sags. The spacing of the rollers 23 is uniformly decreasing from the fixed end of the chain 1 to the movable one by a multiple of the step of the links 6 of the chain 1. The spacing of the openings 26 of the guides 22 of the storage area 8 is made in accordance with the spacing of the rollers 23. Irregularity

The positioning of the rollers 23 along the chain 1 is caused by the fact that when the articulated chain 1 moves in the storage area 8, the rollers 23 are not all simultaneously above the openings 26 of the guides 22 of the storage area 8. The roar is the numbered change in the pitch of the rollers 23 by a multiple of the step 6 the hinge chain 1 provides for the unification of the fastening of the rollers 23 to the links 6 of the chain 1. The frequency of location of the rollers 23 increases from the fixed end of the chain 1 (fixed on the stationary object) to the movable one (fixed to the movable object) to limit the amount of bending of the upper branch 21 of the chain 1, as the moving object k moves from the zone of the working section 25 to the zone of the section By storing 8, the longitudinal load on links 6 of chain 1 increases in the direction from the fixed end of the chain to the moving and most loaded section of chain 1 (in the area near the moving end of the chain)

5 swelling.

The design of the links of the hinge chain 1 is as follows. The end part of the links 6, which lies above the axis of the hinges 7, is right, and the end part, which lies below the axis of the hinge 7, has a bevel at an angle that bends the hinge chain 1 in one direction with a given radius R. The angle is determined from the ratio 5

where a is the distance between the axes of the hinges;

R is the bending radius at the hinge centers.

This design of the links 6 allows the chain 1 to carry both its own and additional (useful) weight loads, which allows for the presence of openings in the guide working areas 25, -hack and in the guide sections of the storage area 8. The width of the openings 26 (FIG. .) is equal to, determined from the ratio IT () (2R4-4r-h) / -radius of the roller; -the thickness of the guide; R., is the radius of the circle approximating the cycloid along which the most distant point of the roller moves when the chain 1 moves from the guides 22 to the middle tray 1b. / П f ly .--. (Rt where R is the bending radius of the chain along the centers of the rollers. The device operates as follows. When moving the moving object 4 from the area of the storage area 8 in the direction of the working section 25 of the hinge, chain 1 is folded up and begins to spread in the storage area B into a flat helix , folding from the base and the tray in mutually opposite directions, taking the position shown in Fig. 6. When moving the moving object 4 out of the working storage area, the hinge chain 1 starts to fold, for example, rolls 16 until the bend of AND reaches the bracket 13. Next, the movement of chain 1 is transmitted through the upper branch 21 and the hinge chain 1 is folded, rolling on the base 10 until the movable object k reaches its extreme position in the storage area 8. When moving the hinge chain 1 along the guides 22 of the storage area 8, the rollers 23 are or rolled into the above directions in the direction of movement of the moving object, thereby moving the links 6 of the hinge circuits 1 with guided 4 and 22 storage areas 8 to base 10 and back. The stops 27 and 28 restrict the movement of the moving object i in the extreme left and right positions. As can be seen from FIG. 1, the direct section of the hinge chain 1 of the upper branch 21 does not experience bends during chain movements to the area of the working section 25 and back. Therefore, a chain section can be made rigid, for example, from a section of a rectangular pipe (Fig. 3).
