Deflection device on tow or hanging cableway

The invention relates to a deflection device on the towing or suspension cableway for the conveyor cable provided with load carriers a circulating member supporting the hoisting rope at the deflection point.

Since, especially in chair lifts and drag lifts for people, the load carrier or rope clamps attacking the hoisting rope each have a transverse arm protruding from the rope to one side, the rope can only be deflected to the opposite side and is therefore used in previously known deflection devices with its from the ge called the transverse arm on the side facing away from the horizontal deflection wheel or circulating element. In the case of a self-contained hauling rope, this can be easily achieved for one of its two strands that characterize the railway line, whereas a deflection with several deflection wheels is required for the other strand Ί so that this strand of the rope can also be supported on the side _{facing away from the cross arm.} However, such diversion bars are structurally complex.

The present invention seeks to avoid these disadvantages and consists in the fact that the circulating element has a large number of circulating ' direction carries a number of forming support bodies for the hoisting rope, each in the same way out of alignment in their support position for the row formed by the rope are movable, and that to hold the support bodies in and to move them out of and into their apes » support position control means are provided, weleh © with the respective Entry of each load carrier protruding against the support body on the hoisting rope into the deflection point required © Lüoke in the Open the row of support bodies by moving at least one of them away.

An exemplary embodiment of the subject matter of the invention is given below explained in more detail using the accompanying drawing » Show it

Fig. 3 is a horizontal section along the line III - III of Fig.2, through part of the periphery of the deflection wheel with side by side located support bodies, and

Fig. 4 is a vertical section corresponding to Fig.2 with from the Support position raised support body.

On the hoist rope 1 of a towing or suspension cableway, the load suspension 2 are each attached by means of a rope clamp 3, which has a transverse arm 4 protruding from the rope 1 to one side _o To deflect the rope from the feed direction to the side of these arms 4 is a horizontal deflection wheel 5 stored in the usual way on a support, not shown. At its periphery, the wheel 5 carries a large number of identical support bodies 6, which form a row in the direction of rotation, for the rope 1, each with a T-Fro »-ill 7 (FIG. 3) in a corresponding courage 8 of the wheel rim of the .. , Abieiikrades 5 are guided axially displaceable and other -,.

Between each "Ab st Ut 25-body 6 of the whole row and one © above this arranged retaining ring 10, which rotates together with the deflection wheel 5, - a compression spring 11 is installed, the pressure from above on the corresponding support body 6 seeks to keep the same in the support position required for the entry of the hoisting rope 1 into the groove 9 _o In this position (FIG. 2) the support body with a shoulder 12 protruding toward the wheel lies on the raised edge 13 of a stationary above the deflection wheel 5. The ring-shaped edge 13 serves as a control cam for vertically moving the stem bodies, which slide with their shoulder 12 along the upper edge of the edge when the wheel 5. is turned, Deflecting wheel located point of the disc circumference an increase 15 on ( _{Fig. 4) s} through which the -darüb © rgl @ itenden support bodies are raised so far that in the

Gap 16 created underneath in the rest of the row of support bodies if necessary, a rope clamp 3 approaching with the rope 1 can enter unhindered with its transverse arm 4. The support bodies sink on the slope of the elevation 15, which decreases at the point of entry under the pressure of their helical springs 11 gradually back into the support position so that their groove 9 is the incoming Can accommodate rope 1. However, if a rope clamp 3 in the Gap 16 has occurred, this rope clamp holds back one or more of the raised support bodies as it descends until the rope clamp exits after the deflection point for the rope from the deflection device and now also this or this support body in the Get back support position.

In the case of the support bodies, the shoulder 12 can have a role or be formed by one which rolls on the upper side of the edge 13 when the deflection wheel 5 rotates. The fixed control cam but can also only consist of the gradually increasing and decreasing elevation 15 over which the support bodies slide or roll, whereas they stand in the support position on the deflection wheel itself in the axial direction.

Instead of this stationary control cam, control means can just as well be rigidly attached to each cable clamp of the load suspension system each consisting, for example, of a shield-like arched shoe that protrudes sideways from the rope clamp and is located directly in front of the Entry of the rope clamp into the area of the support body of the deflection wheel pushes under the support body (s) that can be reached and, as a result of further penetration, lifts over its inclined surfaces. This creates the support body at the right place in the row the required gap that is created when the rope clamp runs out of the area of the deflection point as a result of the The shoe closes again in that the raised support body or bodies automatically sink into the starting position.

Instead of the deflection wheel, a revolving element in the manner of a caterpillar, a belt or a chain could be provided on which the support bodies could be slidably mounted or each rotatable about an axis, but in the latter case locking means must be available, which normally hold the support body non-rotatable and only when a rope clamp enters release their area.
