Since the vehicles are coupled to their associated hoisting ropes, the movement of the vehicles is controlled by the drives of the hoisting ropes. Since the lengths of these hoisting ropes are limited, it is further known to provide at least two hoisting ropes in succession in each of the two directions of travel. This makes it possible, on the one hand, to design such systems for the transport of persons of any length. On the other hand, since the vehicles are coupled to the individual hoisting ropes, this also makes it possible to control the movement of the individual vehicles independently of one another. By stopping the drives of the hoisting ropes the vehicles coupled to these hoisting ropes are brought to a standstill, whereby they can be boarded or left by passengers.

In known systems of this kind, there is a requirement to decouple the vehicles at the end of a hoisting rope in the direction of movement from the latter and to couple them to the following hoisting rope. In order to make this possible, it is known to arrange the end regions of the two conveying ropes next to one another and furthermore to make the at least one coupling device provided on the vehicles adjustable transversely to the direction of movement of the vehicles. Once the vehicles have reached the end of the first hoisting rope, they are disconnected from the first hoist rope, the clamping device provided on these vehicles is further adjusted transversely to the course of the two hoisting ropes and the vehicles are coupled to the subsequent hoisting ropes, whereby they in the sequence this hoist rope to be moved.

a third embodiment of the device for adjusting the Seiltrume, in view and in different phases of the coupling process.

The in the FIG.1 and 1A shown plant for the transport of persons has two end stations 1 and 1a, between which two approximately parallel lanes 11 and 12 are located, along which by means of four hoisting ropes 21, 22, 23 and 24 four vehicles 3 are moved. From the end station 1, a first conveyor rope 21 goes away, which leads to a middle station 1b and to which a second conveyor rope 22 connects, which extends to the second end station 1a. Approximately parallel to this runs a third conveyor rope 23, which starts from the second end station 1a, which likewise extends to the middle station 1b and to which a fourth conveyor cable 24 leading to the first end station 1 connects. The hoisting ropes 21, 22, 23 and 24 are guided at their ends via deflection pulleys 20 and baffles 20a, which are mounted on approximately horizontally oriented axes. At least one of the deflection pulleys 20 of each of the hoisting ropes is assigned a drive motor 25. The vehicles 3 can be coupled to the respective upper Seiltrume the hoisting ropes 21 to 24.

The operation of this system takes place in that a vehicle 3 along the lane 11 1 is moved by the first end station 1 by means of the hoisting rope 21 to the middle station 1b. Subsequently, this vehicle 3 is coupled to the second conveyor rope 22, by which it is moved to the second end station 1a. As a result, this vehicle 3 is moved along the track 12 from the second end station 1a to the middle station 1b and from this to the first end station 1. *** " In an analogous manner, the other vehicles 3 are also moved along the carriageway 11 in a first direction by means of the hoisting ropes 21 and 22 between the terminal stations 1 and 1a and the middle station 1b and along the carriageway 12 in the opposite direction by means of the hoisting ropes 23 and 24. Since the individual vehicles 3 are each coupled to only one of the hoisting ropes 21 to 24, they are made individually by the drives 25 for the hoisting ropes 21 to 24 emotional. Thus, they are stopped by stopping the respective associated drives 25, where they can be boarded or left by the passengers.

Since on each route successively any number of hoisting ropes, to each of which a vehicle 3 or a group of vehicles can be coupled, are provided on the one hand a number of hoisting ropes corresponding number of vehicles 3 or groups of vehicles can be provided in the system and the system can arbitrary Have lengths.

In known such systems for the transport of persons, the coupling of the vehicles from a hoisting rope to a subsequent hoisting rope takes place in that the mutually associated end regions of the hoisting ropes are adjacent to one another and that the respective clamping device provided on the vehicles is adjustable transversely to the course of the hoisting ropes. The coupling of a haul rope on the subsequent hauling rope is carried out in that the vehicle in question is disconnected from a hoist rope by opening the clamping device, that then the clamping device is adjusted so that it passes to the further haul rope and that then brought the clamping device in its closed position is, whereby this vehicle is coupled to the further hoisting rope. For the operation of such a system is thus the requirement that each of the vehicles is formed with an adjustable clamping device.

In contrast, in a system according to the invention for the transport of persons adjusting devices for the dreams of the hoisting ropes are provided, through which the hoisting ropes are guided in the coupling areas in the located on the vehicles, located in its open position clamping devices. Thus, there is no need to make the clutch terminals adjustable transversely to the direction of movement of the vehicles.

In FIG.2 is one of those sections of the system according to the invention for the carriage of persons shown in which the vehicles 3 are reversed from one hoisting rope to another hoisting rope. In this section are the end portion of the first conveying cable 21, which is guided over a guide roller 20c and an eccentric disc 20a, and the end portion of the second conveying cable 22, which is guided over a deflection roller 20d and over a deflection plate 20b. Between the two deflection pulleys 20a and 20b there are at least two devices 4 for adjusting the respective upper runs 21a and 22a of the conveying ropes 21 1 and 22 in the horizontal direction. In addition, there are three devices 5 for adjusting the respective upper runs 21a and 22a of the conveying cables 21 1 and 22 in the vertical direction in this section. At the bottom of the vehicle racks 31 are four clamping devices, by means of which the vehicles 3 can be coupled to one of the conveying ropes 21 and 22.

Like this from the 2A and 2B it can be seen, the means 4 for adjusting the upper strands 21a and 22a of the conveying cables 21 and 22 each have two these dreams 21a and 22a associated actuating lever 41, at their free ends in each case a control roller 42 is mounted, which by means of a hyraulische or pneumatic actuator cylinder 43 is pivoted to the Seiltrume 21a and 22a out, whereby either the Seiltrum 21a or the Seiltrum 22a is adjustable in the horizontal direction. According to these representations, the cable run 22a has been adjusted by the associated adjusting rollers 42 from the dot-dashed position in a middle position relative to the vehicle 3, whereby it is located below arranged on the vehicles 3 clamping devices.

In an analogous manner, the Seiltrum 21a can be adjusted by means of the respective other adjusting rollers 42 in this middle position.

Like this from the FIG.2c and FIG.2d it can be seen, the means 5 for vertical adjustment of a Seiltrumes, in the given case of Seiltrumes 22a, each having a lever 51, on which a control roller 52 is mounted, through which the Seiltrum concerned by means of a hydraulic or pneumatic actuator cylinder 53 in such an altitude it is adjustable that it reaches into the provided on the vehicle 3, located in its open position clamping device. The longitudinally of the system from each other at a distance devices 5 for height adjustment of Seiltrume are hinged to a common control rod 50.

In Figure 2c the starting position of the adjusting rollers 52 is shown. In Figure 2d is that position of the adjusting rollers 52 shown in which the Seiltrum 22a has been adjusted upwards. Instead of the adjusting cylinders 43 and 53, electric servomotors can be provided. The adjustment of the Seiltrume takes place in at least approximately horizontal or at least approximately vertical direction.

Like this FIG.3 it can be seen, the vehicles 3 chassis 31, on which vehicle tires 32 and guide rollers 33 are mounted, by means of which the vehicle 3 along rails 30 is movable. Furthermore, 31 damping elements 34 are provided in the chassis. On the underside of the chassis 31 there are four clamping devices 6, which are operated in those areas in which a reversal of the vehicles 3 takes place.

Each clamping device 6 has a frame-fixed clamping jaw 61 and a movable clamping jaw 62. The adjustment of the movable jaw 62, which is located on a lever 63, in its open position by a stationary hydraulic or pneumatic actuating cylinder 64 via a control lever 65, a control roller 66 and two actuating arms 67 and 68 against the action of a compression spring 69, through which the jaws 61, 62 are brought into their closed position.
Instead of the adjusting cylinder 64, an electric servomotor may be provided.

• Gemäß der FIG.3a ist ein Fahrzeug 3 mittels der an dieser befindlichen Klemmbacken 61 und 62, welche sich unter Wirkung der Druckfeder 69 in ihrer Schließstellung befinden, an das Seiltrum 21a angekuppelt, durch welches es längs der Schienen 30 verfahrbar ist.
• Gemäß der FIG.3b sind die Klemmbacken 61 und 62 mittels des Stellzylinders 64 entgegen der Wirkung der Druckfeder 69 geöffnet worden, wodurch das Seiltrum 21a aus diesen heraus gelangt ist und das Fahrzeug 3 vom Seiltrum 21a abgekuppelt worden ist.
• Um das Fahrzeug 3 an das obere Seiltrum 22a des zweiten Förderseiles 22 anzukuppeln, werden, wie dies aus FIG.3c ersichtlich ist, die in horizontaler Richtung verstellbaren Stellrollen 42 zum Seiltrum 22a hin bewegt, wodurch dieses in eine Lage unterhalb der geöffneten Klemmbacken 61 und 62 gelangt.
• Wie dies aus Fig.3d ersichtlich ist, werden in der Folge die Stellrollen 52 aufwärts bewegt, wodurch das Seiltrum 22a zwischen die in ihrer Offenstellung befindlichen Klemmbacken 61 und 62 hinein gelangt.
• Sobald hierauf der Stellzylinder 64 dahingehend gesteuert wurde, dass die Klemmbacken 61 und 62 durch die Druckfeder 69 wieder in ihre Schließstellung gebracht wurden, und weiters die Stellrollen 42 und 52 in ihre Ausgangslage zurückverstellt werden, wie dies in FIG.3e dargestellt ist, ist das Fahrzeug 3 an das obere Seiltrum 22a des Förderseiles 22 angekuppelt, wodurch es von diesem zur nächsten Station hinbewegt werden kann.

The following is based on the 3a . 3B . 3 c . 3 d and 3E the coupling process explains:

• According to the 3a is a vehicle 3 by means of the jaws located at this 61 and 62, which are under the action of the compression spring 69 in its closed position, coupled to the Seiltrum 21 a, by which it is movable along the rails 30.
• According to the 3B the clamping jaws 61 and 62 have been opened by means of the adjusting cylinder 64 against the action of the compression spring 69, whereby the Seiltrum 21 a has come out of these and the vehicle 3 has been uncoupled from Seiltrum 21 a.
• To couple the vehicle 3 to the upper Seiltrum 22 a of the second hoisting rope 22, as is apparent from 3 c it can be seen, the adjustable in the horizontal direction adjusting rollers 42 moves towards Seiltrum 22a, whereby this comes into a position below the open jaws 61 and 62.
• Like this 3 d it can be seen, the adjusting rollers 52 are moved upward in the sequence, whereby the Seiltrum 22 a between 61 located in its open position jaws 61 and 62 enters.
• Once thereupon the actuating cylinder 64 has been controlled to the effect that the clamping jaws 61 and 62 were brought by the compression spring 69 back into its closed position, and further the adjusting rollers 42 and 52 are zurückverstellt to its original position, as in 3E is shown, the vehicle 3 is coupled to the upper Seiltrum 22 a of the hoisting rope 22, whereby it can be moved from this to the next station.
