Description

The subject invention relates to a cable car system with a support or hoisting rope, which are located on support rods driving equipment, such as armchairs or cabins, fastened by means of terminals, which is further guided in the stations via deflection plates, of which at least one is driven, and which Moreover, between the stations via support rollers or under hold-down rollers is guided, wherein a first strand of the support or conveying rope is guided over at least one deflection disc or a group of deflection rollers and the second strand is passed over at least one deflection drum, which is formed with at least one recess for receiving the support rod of the driving means, whereby the two strands are movable in a path having at least one bend.

Known cableway systems have a support and hoisting rope to which driving resources, such as chairs and cabs, are clamped. The driving equipment to the support and hoisting rope are either firmly clamped or they are releasably clamped, the driving resources are uncoupled in the stations of the support and hoisting rope and moved through this with respect to the speed of the support and hoisting rope significantly reduced speed , whereby they can be boarded or left by the passengers. The attachment of the driving equipment on the support and hoisting rope is carried out by means of clamping devices, which are formed at one of the two ends with jaws and at the other end of the upper portion of a support rod is fixed, at the lower end there is a driving means.

The carrying and conveying cable is guided in the stations via deflecting disks, of which at least one is drivable. Furthermore, the support and hoisting rope is held over the course of the route of the cable car system by means of carrying rollers or passed under hold-down rollers. The clamping devices or the support rods are located in relation to the Seilumlenkscheiben laterally outside of the support and hoist rope, which makes it possible to guide around the support and hoisting rope with firmly clamped driving equipment on the located in the stations deflecting.

Due to the topographic conditions in a terrain in which a cable car system is built, it would often be appropriate, the route of this cable car system form with at least one bend. Inasmuch as a first strand of the support and hoisting rope is affected, it is possible to guide this by at least one baffle or a group of baffles to which the inside of this Trumes the support and hoisting rope comes to rest, whereby the route with a bend can be provided. However, only such a bend is possible, in which the inside of the supporting and conveying cable rests against the deflecting disc, since on the outside of the supporting and conveying cable are the carrying rods for the driving means, which does not know about known from the prior art baffles can be moved away.

Even if one of the two strands of the carrying and conveying cable is guided along a path formed with at least one angled section, the fact remains that it is not possible due to the support rods located on the outside of the support and conveying cable, the second strand along a To lead approximately parallel to the first strand running route. Rather, there is then the need to guide the second strand along a deviating from the route of the first dream route. However, such a cable car system is so far very disadvantageous, since on the one hand requires an approximately doubled number of support posts and on the other hand, there is a significantly increased demand for footprint. For these two reasons, ropeway systems are usually built with a straight line course.

From the EP 556139 B1 is a cable car system with armchairs known, which is formed with a deflector, by which this problem is to be solved. This deflection device consists of a deflection disc, which is formed on the one hand with a recess for receiving a support rod and on the other hand with a plurality of deflection rollers. As long as there is no support bar for a chair on the support and hoisting cable, this deflecting disk is in a predetermined rotational position and the carrying and conveying cable is guided over the deflecting rollers. As soon as a support rod approaches, the baffle is rotated, the support and hoisting rope comes directly to this plant and the support rod for the armchair in question is taken up by the recess located in this. Subsequently, the baffle is rotated to its original position, in which it is stopped until the next support rod arrives.

This known device is disadvantageous for several reasons:
Since the carrying and conveying cable is guided over a plurality of deflection rollers with a very small diameter, very large pressure loads occur in the carrying and conveying cable, as a result of which it is subject to severe wear. In addition, these deflection rollers require a high maintenance, they are very prone to failure and cause them strong noise development. Furthermore, a minimum distance of the successive support rods from each other is required by the structural design of this deflector. In addition, this baffle must be assigned a drive motor, by which it is rotated from the rest position in rotation. Finally, it is not possible with this deflection device to move the carrying and conveying cable against the normal conveying direction.

The subject invention is therefore based on the object to provide a cable car system, the route is formed with at least one angling, but the disadvantages existing in known such cable car systems are avoided. This is inventively achieved in that the second Trum associated deflection drum, which is continuously rotated by the support or hoisting rope, is provided with a plurality of recesses distributed over the circumference of which received the support rods for the driving resources in their movement on this deflection drum become. Preferably, the deflecting drum provided with recesses distributed over its circumference is formed with a conical lateral surface and an adjusting device is provided, by means of which the deflecting drum can be adjusted in its vertical position. Preferably further groups of support and hold-down rollers are provided in the course of the second dream of the carrying or conveying cable before and / or after the deflection drum, through which the second strand is held in a predetermined altitude. Alternatively, the deflecting drum can be unadjustable in its vertical position and the carrying or conveying cable can be assigned at least one guide roller which can be adjusted in height by means of an adjusting device, by means of which the carrying or conveying cable can be adjusted in its vertical position relative to the deflecting drum.

According to further preferred embodiments, the deflection drum is assigned at least one measuring device, by means of which a deflection drum approaching driving means is detectable and is further provided a control device by which the adjusting device for the deflection drum or for the at least one guide roller is controllable. Furthermore, the deflection drum can also be formed with a measuring device, by means of which the rotational position of the deflection drum can be determined and whose output signals are likewise guided to the control device. Finally, the adjusting device may be associated with a measuring device by which the height position of the deflection drum or the at least one guide roller for the support or hoist rope is determined and whose output signals are also guided to the control device.
In addition, other measuring devices are provided for checking or for supplementary control.

In the FIG.1 . FIG.2 and FIG.3 is a section of a cable car system shown, which is formed with a bend. This cable car system has a support and hoisting cable 1, which is guided in the stations via deflecting pulleys. To the support and hoisting rope 1 21 spaced armchair 2 are coupled by means of support rods. In this case, the chairs 2 coupled to the strand station 1 moving to the top station are occupied by persons, whereas the armchairs 2 coupled to the strand 1 moving to the bottom station are unoccupied. In order to effect an angling of the route, a plurality of supports 3 are provided, on which a plurality of groups of deflection rollers 4 are mounted, to which the moving to the top station strand 1a comes to rest, whereby this is deflected in the direction of movement to the mountain station to the right. This is possible because the support rods 21 for the chair 2 are located on the outside of Trumes 1a, whereas the inside comes to the deflection rollers 4 to the plant.

In order to be able to deflect the strand 1b moving in the corresponding manner to the valley station, a deflection drum 6 is provided on a support frame 5, which is formed with a plurality of equidistant recesses 61 over its circumference. These recesses 61 are therefore necessary because the support rods 21 are located on that side of the support and conveying cable 1, which comes to the deflection drum 6 to the plant. It must further be ensured that the deflection drum 6 is on arrival of a chair 2 in a position such that the support rods 21 of the armchair 2 in question are received by one of the recesses 61.

In order to achieve this, the outer surface of the deflection drum 6 is conical, with this conical surface tapering downwards, and furthermore the deflection drum 6 can be adjusted in its vertical position by means of an adjusting device. For this purpose, the deflection drum 6 is rotatably mounted about a vertical axis at a height adjustable support bar 51. Furthermore, the deflection drum 6 associated groups of support and hold-down rollers 7, through which the strand 1b of the support and hoisting rope 1 is held in a predetermined altitude. In addition, the deflection drum 6 is associated with a first sensor 81, by which the passage of a support rod 21 is detected. The output signal of this sensor 81 is applied to a control unit, by which, taking into account the rotational position of the deflection drum 6 existing at that time, the height of the conical deflection drum 6 must be calculated in order to ensure that the subsequently arriving support rod 21 is received by one of the recesses 61 of the deflection drum 6. To control a second sensor 82 is provided, which is located at a smaller distance from the deflection drum 6. In addition, there is a third sensor 83 after the deflection drum 6, through which after the passage of the respective support rod 21, the adjusting device for the height adjustment of the deflection drum 6 is released again.

Characterized in that the lateral surface of the deflection drum 6 due to their conicity has different diameters at different altitudes, is carried out by the height adjustment, a change in the distance of the recesses 61 relative to a carrier and conveyor rope 1 located support rod 21 which is adjustable such that the advancing support rod 21 in one of the recesses 61 of the Ablentrommel 6 arrived.

The adjustment of the support beam 51, on which the deflection drum 6 is mounted, takes place by means of two in particular FIG.3 apparent adjusting cylinder 9. Furthermore, there are four telescopic guides 9a between the support frame 5 and the support bar 51. Furthermore, there are four measuring devices 84 between the carrying device 5 and the support bar 51, by means of which the height position of the deflecting drum 6 can be detected and whose output signals are likewise guided to the control unit. Out FIG.4 is further seen that the deflection drum 6 is formed with a fifth measuring device 85, through which the rotational position of the deflection drum 6 is detected and whose output signals are also applied to the control unit.

Out FIG.5 the formation of the deflection drum 6 can be seen. As can be seen, the deflection drum 6 is formed with a hub 62, from which radially erstrekkende web plates 63 go out, wherein between two mutually associated web plates 63 each have a recess 61 for receiving the support rods 21 of the chair. 2 located. Furthermore, it can be seen that the outer circumferential surface 64 is tapered downwards conically. The conicity of the deflection drum 6 is about 17 °. Depending on the altitude of the deflection drum 6, the adjacent strand of the support and conveying cable 1 is in different areas of the lateral surface 64, wherein upper portions of the lateral surface 64 of the rotational axis relative to lower portions of the lateral surface 64 are at greater radial distances. The lateral surface 64 of the deflection drum 6 is formed with a rubber pad.

• In den FIG.6, FIG.6a und FIG.6b sind das Trum 1b des Trag- und Förderseiles 1, eine Tragstange 21, die mit Ausnehmungen 61 ausgebildete Ablenktrommel 6 und die drei Sensoren 81, 82 und 83 schematisch dargestellt.
• In FIG.6 befindet sich die Tragstange 21 im Bereich des erstens Sensors 81, wodurch der Abstand dieser Tragstange 21 zur Drehachse der Ablenktrommel 6 bestimmt ist. Durch das vom ersten Sensor 81 abgegebene Ausgangssignal und unter Berücksichtigung der durch den fünften Sensor 85 ermittelten Drehlage der Ablenktrommel 6 zu diesem Zeitpunkt wird von der Steuereinheit berechnet, in welcher Höhenlage sich die konische Ablenktrommel 6 befinden muss, dass die sich zur Ablentrommel 6 hin bewegende Tragstange 21 in eine der Ausnehmungen 61 der Ablenktrommel 6 hineingelangt.
• In FIG.6a befindet sich diese Tragstange 21 im Bereich des zweiten Sensors 82, durch welchen an die Steuereinrichtung ein Signal abgegeben wird, durch welches mittels der Steuereinheit eine Überprüfung der Drehlage der Ablenktrommel 6 dahingehend vorgenommen wird, dass diese Tragstange 21 in eine der Ausnehmungen 61 der Ablenktrommel 6 hineingelangt. Sofern dies nicht gewährleistet ist, wird die Seilbahnanlage abgeschaltet. In der Folge erfolgt vorerst keine weitere Höhenverstellung der Ablenktrommel 6.

The following is based on the FIG.6, FIG.6a and FIG.6b the function of this deflection drum 6 is described:

• In the FIG.6, FIG.6a and FIG.6b are the strand 1b of the support and hoisting rope 1, a support rod 21, which formed with recesses 61 deflection drum 6 and the three sensors 81, 82 and 83 shown schematically.
• In FIG.6 is the support rod 21 in the region of the first sensor 81, whereby the distance of this support rod 21 is determined to the axis of rotation of the deflection drum 6. By the output from the first sensor 81 output signal and taking into account the determined by the fifth sensor 85 rotational position of the deflection drum 6 at this time is calculated by the control unit, in which high position the conical deflection drum 6 must be that moving towards the Ablentrommel 6 out Support rod 21 in one of the recesses 61 of the deflection drum 6 in it.
• In 6A is this support rod 21 in the region of the second sensor 82, through which a signal is output to the control device, by means of the control unit, a check of the rotational position of the deflection drum 6 is made to the effect that this support rod 21 in one of the recesses 61 of the deflection drum. 6 enters. If this is not guaranteed, the cable car system will be switched off. As a result, no further height adjustment of the deflection drum 6 takes place for the time being.

After the support rod 21 has been received by one of the recesses 61 of the deflection drum 6, has been moved with this and has left this recess 61 again, it enters the region of the third sensor 83, through which an output signal is delivered to the control unit, that subsequently a height adjustment of the deflection drum 6 can be made again to thereby allow the required height adjustment for the support rod 21 of another chair 2.

Alternatively, the deflecting drum 6 can be unchangeable in its vertical position, wherein the supporting and conveying cable is assigned at least one guide roller which can be adjusted by means of an adjusting device in its vertical position, through which the carrying and conveying cable in its altitude relative to the conical deflection drum 6 is adjustable. This also causes the necessary control to the effect that the support rod 21, which moves toward the deflection drum 6, enters one of the recesses 61 of the deflection drum 6.
By these controls it is ensured that the moving towards the deflection drum 6 support rods 21 for armchair 2 always get into one of the recesses 61 of the deflection drum 6. In this way, the second strand 1b of the carrying and conveying cable 1 can be deflected analogously to the first strand 1a of the carrying and conveying cable 1.

With such a device can thus be built cableway systems with any number of bends in any direction, whereby the course of the cableway systems can be adapted to any topographical conditions. In such a cable car system also the direction of movement can also be changed, ie it can also be made backward movements.
Such a device can also be provided in a cable car installation with a fixed carrying cable and with a pulling cable, wherein the pulling cable is guided over the deflection drum formed with recesses.
