"Energy supply chain"

The invention relates to an energy supply chain for cables or wires with a stationary and a movable cable or wire end with articulated chain links made up of chain plates arranged parallel to one another and at a distance from one another, as well as webs connecting the plates in pairs.

Such energy supply chains are known to the person skilled in the art without the need for a method of manufacture.

The invention is based on the task of securing the area between the last chain link or the last chain links at the ends of the chain and the stationary or the movable line or cable connection, i.e. protecting the lines or cables emerging from the ends of the energy supply chain from entering the line connection. The means used here should not only be simple in their structural design, but also

be labor-saving in their installation such that the said gap between the line or cable connection and the last chain link or the last chain links is safely covered regardless of their connection.

According to the invention, in an energy supply chain according to the generic term of the main claim, the features of the characterizing parts of this claim are proposed. The features of the main claims characterize advantageous further developments of the features of the main claim.

The cover box of the energy supply chain according to the invention offers the advantage that the cover box is first placed on the chain due to the possibility of being moved lengthways on the chain, and then brought into its final or use position, where it rests with one of its front edges on the line or cable connection and is releasably clamped to one of these links in this position, covering the space between the last chain link or the last chain links. - To remove the cover box, it is sufficient to first detach the cover box from the last or one of the last chain links by unscrewing the clamping screw, in order to then gain the possibility of moving the cover box a little lengthways on the chain.

and then, if desired, remove from the chain.

The drawing shows exemplary embodiments of the inventive parts of the energy supply chain, namely

Cover box as used in the design of the chain links according to Fig. 2 to 6 and 8.

The energy supply chain K which accommodates the lines or cables N is made up of chain links 1, 2, 3, 4... which follow one another in the longitudinal direction of the chain and are connected to one another in an articulated manner and consist of parallel, spaced-apart plates 5, 6, between which webs 7 extend, the ends 7a, 8a of which are connected to the plates 5, 6. Due to the similarly designed chain plates, the chain K can bridge a section A in a self-supporting stretch, while it runs curved over a section ß. With its one

At the end KE it is connected to a stationary line or cable connection SA, while the second chain end KZ is connected to a movable line or cable connection BA. The lines or cables N enter the connections BA or SA, whereby the last chain links L3 or IA of the chain ends KE and KZ are kept at a fixed distance from the connection BA or SA, forming a gap Z. The last two chain links L3> L4 of the chain can be connected, for example, by angle pieces 9 to a support 10 of the line or cable connections BA or SA. Another type of fastening is explained in connection with the design of the chain links according to Fig. 9 and 10.

The gap Z between the front wall 11 of the cable or line connection BA or SA is covered by a cover box 12 (Fig. 11), the front edge 13 of which rests against the wall 11 of the connection BA or SA.

The cover box 10 can be placed on the chain at any point on the straight, stretched section A and then moved longitudinally on the chain into its position of use (Fig. 1 and 2) until the front edge 13 of the box lies flat against the front wall 11 of the connection. The front edge

of the box 1? can, if desired, also expand a seal, preferably an elastically flexible seal.

The plates 5» 6 of the successive chain links 1, 2, 3, ^ ... are provided in the embodiment according to Figs. 4 to 6 on the inside and outside with recesses 20 which are T-shaped in cross section and open to the outside, which are arranged in pairs near the upper edge 5a, 6a and the lower edge 5b, 6b of the plates and serve to receive the ends 7a, 8a of the webs 7, 8.

The cover box 12 used again has the shape shown in Fig. 11 and has a hole 21 at the level of the upper of the two outward-facing recesses 20 of one of the tabs, here the tab 5, through which the threaded shaft of a screw 22 projects, onto the end of which a nut piece 23 is screwed, the possible shapes of which are shown in Fig. 7. The nut piece has a square or oblong rectangular shape and is longitudinally displaced in the outwardly open T-shaped groove ^" C" so that the box 12 can be moved in the longitudinal direction of the chain until its front edge 13 comes to rest on the front wall 11 of the line or cable connections BA, SA in the manner described and the nut piece can initially slide in the recess 20. When tightening the

The box 12 is pulled and braced with its side wall 15 against the tab 6 using screw 22. For this purpose, an intermediate layer 40 can be provided on the inside of this wall at the height of the screw 22.

Fig. 8 shows an embodiment of a cover box 12 which has a box part 24 bent by 90° adjacent to its front edge 13, which can extend to a front edge 25 or a front edge 25a. In this box part, the lines or cables N are held by spacers (not shown) in the same way as between the tabs 5, 6.

As can be seen from the above, the cover box is connected to the end links of the chain independently of the fastening of these links to the moving or stationary machine part.
