Definitions

  • the subject matter of the invention relates to an energy supply unit for guiding lines between a fixed connection point and a connection point movable around a central axis and on a spatially curved path.
  • EP 0 277 389 B1 discloses an energy supply unit for guiding lines between a stationary connection point and a connection point which is movable about a vertically running central axis and on a spatially curved path.
  • This energy supply unit is formed by articulated chain links.
  • Each chain link has two sides arranged approximately parallel to one another. The sides are connected by a base plate. Furthermore, the sides of the chain links are connected to each other by removable webs.
  • Each side of a chain link has an engagement connector at one end area and a slot-shaped receptacle at the other end area. The engagement connectors of one chain link engage in the slot-shaped receptacles of the adjacent chain link. Two adjacent chain links are connected using dowel pins.
  • each chain link is at an angle to each other.
  • the intersection of the axes defines a center of curvature of the energy supply unit, so that it is movable about a central axis and on a spatially curved path.
  • the outside of the chain links are longer than the inside of the chain links.
  • the energy supply unit assumes an inclined position.
  • WO 98/31950 discloses a further embodiment of an energy supply unit for guiding lines between a fixed connection point and a connection point which is movable about a central axis and on a spatially curved path.
  • This energy supply unit has link plates which are connected to one another in an articulated manner and can be angled against one another.
  • the hinge axes of the link plates intersect, so that movement of the energy supply unit on a spatially curved path is made possible. During the movement of the energy supply unit on a spatially curved path, it assumes an inclined position.
  • the chain links are formed by only one side. Support means are provided on at least some sides to accommodate the lines to be routed.
  • the formation of an energy supply unit with a single strand, which is formed by side plates of the chain links, is known from GB 1, 073.438.
  • the individual chain links have suspension elements for receiving lines
  • the energy supply units known from EP 0 277 389 B1 and from WO 98/31950 have the disadvantage that the path radius is always determined by the angle at which the joint axes of each chain link intersect.
  • energy supply units are necessary in which the joint axes intersect at different angles.
  • the energy supply unit should make use of the fact that practically the entire load of the energy supply chain is absorbed by the outer side strand, so that it is transferred to another
  • the present invention is based on the objective of developing the known energy supply unit in such a way that the energy supply unit can follow spatially curved paths with different radii without the expenditure for adapting the energy supply unit to this requirement being high.
  • Another object of the invention is to develop the known energy supply unit in such a way that it can be moved without guide channels essentially independently of the size of an angle of rotation.
  • an energy supply unit for guiding lines between a fixed connection point and a connection point which is movable about a central axis and on a spatially curved path, with the features of claim 1.
  • Advantageous further developments and refinements of the energy supply unit are the subject of the dependent claims.
  • the power guide unit according to the invention for guiding lines between a fixed and a connection point movable about a central axis and on a spatially curved path with articulated link plates which form at least one strand and with suspension means arranged on at least some link plates is distinguished by that the hinge axes - first and second hinge axes - of adjacent chain links are offset by a circumferential angle of 90 ° to one another and the link plates can be pivoted essentially only in the direction of the central axis and back about the first link axes.
  • This configuration of the energy supply unit according to the invention has made it possible to use such an energy supply unit even if the radius of the spatially curved path changes or the energy supply unit is to be used for other rail radii.
  • This configuration of the energy guide chain according to the invention essentially has two articulated axes which allow the link plates to be deflected independently of one another. While the first link axes allow the link plates to be deflected in a plane that is essentially parallel to the link plates, as is the case with conventional energy guiding chains, the second link axes create the possibility of seeing the link plates essentially transversely and thus to pivot towards and away from the central axis.
  • the energy supply unit according to the invention also permits relatively large angles of rotation of the connection point, in particular angles of rotation of> 180 °, without a guide channel having to be provided.
  • the inventive configuration of the energy supply unit provides an inexpensive possibility of producing energy supply units for guiding lines between a fixed connection point and a connection point which is movable about a central axis and on a spatially curved path.
  • the energy supply unit can be constructed from standard link plates.
  • the pivoting angles about the first joint axes are essentially the same. This configuration has the advantage that the energy supply unit runs relatively smoothly.
  • swivel angle limiters are provided, by means of which the swivel angles of the link plates about the first joint axes are limited.
  • swivel angle limiters have the advantage that the deflectability of the Chain links around the first joint axes within a well-defined swivel angle is made possible. It is not absolutely necessary that the swivel angle limiters are always the same.
  • the arrangement of the swivel angle limiter and the swivel angle permitted by the swivel angle limiter can be different, so that the energy supply unit is also suitable for describing a path which is spatially curved with a changing radius. Such a movement of an energy supply unit is not possible either by an energy supply unit according to EP 0 277 389 B1 or according to WO 98/31950.
  • the swivel angle limiters are each detachably connected to at least one link plate.
  • the energy supply unit is expediently constructed in such a way that adjacent link plates partially overlap one another and are connected to one another by articulated openings and articulated pins, the articulated openings and the articulated pins being formed coaxially with respect to the second articulated axis.
