    A suspension clamp for connecting suspension cables (1) and catenaries (2) for electrically operated rail vehicles by means of a hanger rope (3), with two jaws (6, 7), wherein a screw (8) passing through both jaws (6, 7) for clamping the two jaws (6, 7) is arranged. The screw (8) has transversely to its longitudinal extent a through hole (9) through which the hanger rope (3) is inserted. A screwed onto the screw (8) nut (14) clamps the hanger rope (3) in the bore (9). Thus, the length of the hanger rope (3) can be easily changed.

    Description The invention relates to a suspension clamp for connecting suspension cables and overhead contact lines for electrically operated rail vehicles by means of a suspension cable with two clamping jaws which clamp a suspension cable or a contact wire via grippers, with a screw penetrating both clamping jaws and nut for clamping the two Clamping jaws is arranged.
    In many cases it is necessary to change the distance between the suspension cable and the contact wire and thus the length of the hanger rope. When using known hanging clamps, such as e.g. However, this is only possible to a very limited extent in EP 1 243 460 A1 and AT 410 197 B.
    The invention has set itself the goal of creating a hanging clamp with which a change in the effective length of the hanging rope is possible within wide limits.
    This is achieved in that the screw has a through hole transverse to its longitudinal extension, through which the hanging rope is inserted, and that a nut screwed onto the screw clamps the hanging rope in the hole.
    With a hanging clamp according to the invention, the clamping force on the hanging rope can be easily changed by means of the screw and the hanging rope can be moved. This means that its effective length can be changed within wide limits.
    In one embodiment of the invention, two tensioning disks are arranged, each having a semicircular opening for receiving the hanger rope and are movable relative to one another by the nut arranged for clamping the two clamping jaws.
    The screw is advantageously a hinge screw.
    In an expedient embodiment of the invention secure outwardly projecting reinforcing ribs of the clamping jaws against the tensioning discs.
    In a further embodiment of the invention, the locking washers for securing against rotation have the square area of the hinge screw adapted openings.
    In the event of improper operation, the two clamping jaws could be opened so far that the contact wire was no longer held when loosening the clamping of the hanger rope.
    This is avoided in a further improved embodiment of the invention in that the nut arranged for clamping the hanging rope (3) between the two. Clamping jaws (6, 7) is arranged.
    This nut can therefore be operated independently of the nut acting on the clamping jaws, so that the contact wire cannot accidentally slip out.
    The invention is described in more detail with reference to embodiments shown in the drawings, without being limited to these examples. The show:
    1 and 2 in side and front view the suspension of a contact wire; Fig. 3 a partial section through a hanging clamp according to the invention of a first embodiment Fig. 4 a side view of a hanging clamp according to the invention according to Fig. 3; Fig. 5 a section along the line V-V in Fig. 3 and the 6 and 7 Side and front views of a second embodiment of the invention.
    1 and 2, a contact wire 2 is suspended from a supporting cable 1. The suspension takes place via a hanger rope 3, which is fastened to the suspension cable 1 via a hanger clamp 4 known per se and to the contact wire 2 via a hanger clamp 5 according to the invention in a first embodiment.
    The hanging clamp 5 has two clamping jaws 6 and 7, which are connected to one another on their side opposite the contact wire 2.
    A gate screw 8 with nut 8 'acts on the two jaws 6 and 7 and has in its square area a transverse bore 9 through which the hanger rope 3 is inserted.
    Two clamping washers 10 and 11 each have a groove for receiving the hanging rope 3. The clamping washers 10 and 11 are arranged in the square area of the gate screw 8 and have this square area adapted openings 12. As a result, they are secured against rotation.
    The reinforcing ribs 13 of the jaws 6, 7 also secure the clamping disks 10 against rotation.
    CH 714 208 A2 If the height of the contact wire 2 is to be changed, the nut 8 'of the gate screw 8 is loosened, with which the hanging cable 3 is movable and vertically displaceable, so that the ideal desired height of the contact wire 2 can be set exactly above the top edge of the rail.
    6 and 7 for the clamping of the suspension cable 1 and the contact wire 2 identically designed hanging clamps 5 with their jaws 6 and 7 are arranged.
    As in the embodiment of FIGS. 1 to 5, a screw 8 with a nut 8 'is arranged, through which the supporting cable 1 or the contact wire 2 are clamped via jaws 6, 7.
    The screw 8 also has a bore 9 through which the hanging rope 3 is inserted.
    A nut 14 is screwed between the jaws 6 and 7 on the screw 8, which clamps the suspension cable 3 between a washer 15 and the head of the screw 8. The clamping jaw 7 has a groove 7 'in which the hanging rope 3 is guided.
    The operation of the nut 14 is completely independent of the nut 8 ', an unintentional opening of the jaws 6.7 is therefore excluded.
    [0025] Numerous modifications are possible within the scope of the invention.
