Description

one

The invention relates to devices for supplying energy from a stationary object to a moving object and can be used in the electrical and machine tool industry.

A device is known for pbdvodv energy to mobile consumers, containing a chain with shirenno-connected links and a cable located inside the chain, and in the slots of the chain links are "floating axes 1 |.

A disadvantage of the prior art is the reduction in chain stiffness with increasing length of the upper leg.

It is also known a device for supplying energy to mobile consumers, comprising a chain with articulated joints and cables or hoses located inside the chain, on the sides of the upper branch of the chain are two pairs of supporting guide rails so that the distance between the upper guides smaller than / e than the distance between the lower guides, and on the chain links two rows of support rollers correspond, one of which is located on the upper part of the links, and the upper and lower rollers are shifted

relative to each other on step f2 |. The support guide bars have separate grooves for the passage of the support rollers at the appropriate place of deflection of the chain.

A disadvantage of this device is the complexity of the implementation of the mechanism for supporting the upper branch of the chain, which consists of two level support bars and two rows of rollers. In addition, a chain sag occurs in the device, since when the rollers are placed in one row, each pair of rollers alternates above the grooves, and when the rows of rollers are displaced, they are one above the grooves and do not support the chain in this area, this necessitates an increase in chain stiffness.

The purpose of the invention is to improve the reliability of the device.

This is achieved by the fact that in the proposed device, in each subsequent pair of support rollers, the distance between them is reduced by the width of the two rollers along the chain from the consumer to the source and the slots for the passage of the support rollers are respectively reduced.

I FIG. 1 The proposed device, the overall appearance; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 1. The device consists of a chain with pivotally connected links 1, between which pads 2 are installed with openings 3 for laying cables and hoses. At a distance determined by the rigidity of the chain, there are pairs of rollers 4, which are fixed on axles x 5, installed new links x 1 chains; The distance between the pair of rollers 4 is reduced along the length of the chain from the consumer 6 to the source 7. The device has two guide strips 8 with separate slots 9 for the passage of the rollers 4 located at the appropriate place of deflection of the chain and having the appropriate size. The power supply 7 is connected to the consumer by cables and wires (not shown in the figures). . The device works as follows. In the initial position, most of the chain is in the lower branch. When the consumer 6 moves, the links of the first chain from the lower branch go over the radius to the upper branch, while the pairs of rollers 4, moving, pass through the slots 9 and subsequently, not over the slots, roll along the guides 8, support of the upper branch of the chain from the deflection. Moreover, a pair of rollers 4, which is closer to the consumer and has the greatest width, is passed into the corresponding grooves, is further limited from falling out from the guide, since the subsequent grooves are smaller than the width of these rollers. The same thing happens during the operation of other pairs of rollers 4. When moving to the opposite side of the consumer, 6 pairs of rollers 4 roll freely along the guides 8, and at the moment of approach, the corresponding groove 9 comes out of the guide 8 and the radius goes -on the lower branch of the chain. Claims. A device for supplying energy from a stationary object to a mobile one, containing a chain with hinged links, on the sides of which, equally along the length of the chain, are several pairs of support rollers, two guide rails made from the sides of the upper branch of the chain and having grooves for the passage of the support rollers at the appropriate place of the chain deflection, a flexible pipe located inside the chain, characterized in that, in order to increase the reliability of the device, in each subsequent pair of support rollers DRA of therebetween is reduced by the width of the two rollers along the chain from the consumer to the source, and the slots for the passage of the supporting rollers respectively reduced.
