Definitions

• the invention relates to a suspension for the rail or the like.
• a hoist a carrier according to the preamble of claim 1.
• a redundancy suspension is from a brochure of Demag Material Handling Equipment known for rails (crane tracks and monorails), in which the track is additionally secured with a steel cable. Redundancy suspensions have the task if the actual suspension fails, which is usually caused by a Screw connection is formed to take over the supporting function. For this, the steel cable is turned around placed the upper beam and through the opening of an additional one on the running rail attached support element guided.
• the rope ends are designed as thimbles, which the Firmly connect the rope ends to each other, the rope forming a closed ring.
• the object of the invention is to provide a cable connection for a redundancy suspension to propose where the above Disadvantages are avoided.
• the invention provides that the rope ends releasably together by a connecting element are connected, which consists of two wedge locks connected to each other which are arranged in such a way that one wedge lock is 180 degrees from the other Wedge lock is twisted so that the rope ends entering from opposite directions after deflection around the wedges of the wedge locks, they can be returned against the direction of entry, can be clamped by the wedges at least under load and accordingly the effective directions of the the wedges jamming the rope ends are opposite.
• This ensures that the Rope when a sudden load against the frictional resistance of the Wedge lock tightens, which heats up and the sudden kinetic Absorbs energy.
• each wedge lock a base plate and a patch pocket with a wedge-shaped space for receiving of the corresponding insertable wedge is formed.
• the wedge is expediently freely displaceable in the direction of entry, so that the cable connection can easily be released in a load-free state.
• a simply constructed connector consists of two wedge locks, one have common base plate as a connecting element.
• the wedge angle be in an angular range between 10 degrees and 14 degrees lies.
• FIG. 1 shows the suspension of a running rail 1 on a carrier 2 by means of a bolt 3, which is pivotally connected at the top to a cross member 4 in a small angular range.
• the cross member 4 is fixed to the lower flange 6 of the screw connection 5 double-T-shaped carrier 2 connected.
• the cross member 4 lies with his upper bearing surface 7 on the lower outer surface 8 of the flange below Application of force.
• the bolt 3 is at its lower End also pivotable in a limited angular range with the travel rail 1 connected.
• a rope 9 is provided, via which the carrier 2 and the running rail 1 are connected to one another. This is what happens Rope around the carrier 2 and is passed through the suspension of the rail 1. The ends of the rope 9 are firmly connected to each other, so that the rope 9 a closed ring, which in the event of failure of the suspension holding the Track 1 on the carrier 2 takes over.
• the ends 9a, 9b of the rope are fixed together by a connecting element 10 connected.
• the connecting element 10 is more clearly shown in FIGS. 3 and 4 (top view) detect. It consists of a base plate 11 which carries a wedge lock 12, 13 on each side. So that the two wedge locks 12, 13 are simultaneously with one another via the base plate 11 connected.
• Each wedge lock consists of the common base plate 11 and one pocket 14, 15 fastened thereon, which is molded into a metal sheet.
• the wedge locks are each rotated by 180 degrees to each other; 4 is the top opening 16 of the Wedge lock 12 and the lower opening 17 of the wedge lock 13 can be seen.
• the interior the pockets 14, 15 are wedge-shaped and each have two side surfaces which in their imaginary extension at an acute angle, the wedge angle approach.
• the wedge angle is 14 degrees in the exemplary embodiment.
• In the pocket is one Side a correspondingly shaped wedge 18, 19 insertable, which is essentially the same Has wedge angle.
• the ends of the rope run from opposite directions in the wedge-shaped pockets and then around the wedge led around.
• the wedge 18, 19 is at least freely displaceable in the direction of entry.
• the rope lies in sections transverse to its longitudinal direction on both sides of it Outer circumference on the wedge and on the inner surfaces of the bag; it is after Deflection around the wedges 18, 19 of the wedge locks 12, 13 against their direction of entry returned.
• the rope 9 can be clamped by the wedges 18, 19 at least under load.
• the Directions of action of the wedges 18, 19 clamping the rope ends 9a, 9b are therefore opposite.
• rope clips 20a, 20b - as shown in FIG. 1 - intended.
