This application claims the priority, under 35 U.S.C. §119, of Austrian patent application A 1930/2010, filed Nov. 22, 2010; the prior application is herewith incorporated by reference in its entirety.
The present invention relates to a system for conveying persons, having at least one track along which a plurality of vehicles may be moved by means of a plurality of continuous conveying cables, wherein at least two mutually successive conveying cables are provided in each direction of travel, with each of which at least one drive is associated, as a result of which they may be driven independently of one another, and to which the vehicles may be coupled by means of clamping devices and which overlap one another in the mutually associated end regions, as a result of which coupling of the vehicles may be transferred from a first conveying cable to the successive conveying cable.
Prior systems of the generic kind for conveying persons are described, for example, in U.S. Pat. No. 5,419,261 and its counterpart European patent EP 0 611 220 B1 and in European patent EP 1 193 153 B1. Those systems have two tracks along which vehicles may be moved by way of continuous conveying cables with which drives are associated. Because the vehicles are coupled to the conveying cables associated therewith, movement of the vehicles is controlled by the drives of the conveying cables. Because these conveying cables are limited in length, it is further known to provide, in each of the two directions of travel and mutually successively, at least two conveying cables. This makes it possible on the one hand to construct such systems for conveying persons to have any desired length. Because the vehicles are coupled to the individual conveying cables, on the other hand this also makes it possible to control the movement of the individual vehicles independently of one another. Stopping the drives of the conveying cables brings the vehicles coupled to these conveying cables to a standstill, whereupon the passengers can disembark and embark on the vehicles.
In the case of prior art systems of this kind, it is necessary to uncouple each of the vehicles from a conveying cable at the end thereof which is in the direction of movement and to couple them to the successive conveying cable. To make this possible, it is known to arrange the end regions of the two conveying cables next to one another and furthermore to construct the at least one coupling device that is provided on the vehicles to be movable transversely to the direction of movement of the vehicles. As soon as the vehicles reach the end of the first conveying cable, they are uncoupled from the first conveying cable, the clamping device provided on these vehicles is furthermore moved transversely to the course of the two conveying cables and the vehicles are coupled to the next conveying cables, as a result of which, as the procedure continues, they are moved by this conveying cable.
The prior art systems for conveying persons are disadvantageous in that the individual vehicles each have to be constructed to have a device for moving the coupling device. These assemblies require maintenance and they increase the weight of the vehicles.
It is accordingly an object of the invention to provide a system for transporting persons which overcomes the above-mentioned disadvantages of the heretofore-known devices and methods of this general type.
With the foregoing and other objects in view there is provided, in accordance with the invention, a system for conveying persons, comprising:
at least one track and a plurality of vehicles to be supported on the at least one track;
a plurality of continuous conveying cables for driving the vehicles along the at least one track, the conveying cables including a first conveying cable and at least one successive conveying cable disposed successively to the first conveying cable and with an overlap region therebetween;
at least one drive associated with each of the successive conveying cables for independently driving each of the conveying cables;
the vehicles each carrying clamping devices configured for clamping the vehicles to respective the conveying cables;
the cables having cable run s overlapping one another in mutually associated end regions thereof to form the overlap region, enabling a coupling of a respective the vehicle to be transferred from the first conveying cable to a successive the conveying cable; and
at least one servo device disposed in the overlap region at which the first conveying cable and the successive conveying cable overlap one another, and configured to move the cable run of the successive conveying cable into the clamping device of a vehicle to be coupled, while the clamping device is in an open position.
In other words, the objects of the invention are achieved in that there is provided, in those regions in which a conveying cable is adjoined by a further conveying cable, at least one servo device which enables the cable run of the further conveying cable to which the vehicle is to be coupled to be moved into the clamping device of this vehicle, which is in the open position.
Preferably, the vehicles are constructed to have at least one clamping device which has two clamping jaws that may be moved into their open position by means of a servo cylinder in opposition to the action of a servo spring.
According to a first embodiment, the servo device may have at least one servo roll or the like by means of which the cable run of the further conveying cable to which the vehicle is to be coupled may be moved in the horizontal direction and, furthermore, may have at least one servo roll or the like by means of which this cable run of the further conveying cable may be moved in the vertical direction. Preferably, the servo device for moving cable runs horizontally has at least one pair of servo rolls or the like, by means of which a respective one of the two cable runs of two conveying cables which are located next to one another may be moved in the horizontal direction, and the servo device for moving cable runs vertically has at least one servo roll or the like, by means of which a respective one of the two cable runs of two conveying cables which are located next to one another may be moved in the vertical direction. Here, the servo device for moving cable runs horizontally may have a plurality of pairs of servo rolls or the like which are located spaced from one another in the longitudinal direction of the system, by means of which a respective one of the two cable runs of two conveying cables which are located next to one another may be moved in the horizontal direction, and the servo device for moving cable runs vertically may have a plurality of servo rolls or the like which are located spaced from one another in the longitudinal direction of the system, by means of which one of the two cable runs of two conveying cables which are located next to one another may be moved in the vertical direction. Here, the servo rolls or the like which are located spaced from one another for moving the cable runs vertically may be movable together by means of a servo rod which extends in the longitudinal direction of the system. Here, furthermore, the servo rolls or the like for moving one of the cable runs in the horizontal or vertical direction may be movable by at least one hydraulic or pneumatic servo cylinder or an electric servo motor.
Here, the cable runs are moved in the at least approximately horizontal direction or the at least approximately vertical direction.
According to a second embodiment, the servo device is formed by a servo frame which is movable in translational motion by means of a servo cylinder or an electric servo motor and which is constructed to have two receiving faces for a respective one of two cable runs which are located next to one another, these receiving faces being able to grasp one of the two cable runs and move it into the clamping device, which is in its open position. Preferably, here, the piston rod of a servo cylinder or the servo motor is articulated to the servo frame, and the servo frame is articulated to two rotatably mounted pivotal arms. Furthermore, the servo frame is preferably constructed to have two prolonged portions which project toward the cable runs and are constructed to have a respective shoulder on the mutually facing sides, these shoulders being able to grasp a respective cable run and move it into the clamping device, which is in its open position.
According to a third embodiment, the servo device is formed by two servo rolls or the like which are guided in slideways by means of a servo cylinder or an electric servo motor, wherein the movement thereof allows one of the two cable runs to be grasped and moved into the clamping device, which is in its open position. Preferably, here, the servo rolls or the like are moved by means of a respective servo lever, which is articulated to a rotatably mounted angled lever, wherein a common servo lever, to which the piston rod of the servo cylinder or the electric servo motor is articulated, is associated with the two angled levers. Furthermore, the two angled levers may preferably each be pivoted clockwise and counterclockwise by the servo cylinder or the electric servo motor, wherein one of the two servo rolls or the like may be moved toward the associated cable run or away therefrom.
In the case of these two further embodiments, it is possible for servo devices located spaced from one another in the longitudinal direction of the system to be connected mechanically to one another for movement together.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a system for conveying persons, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
Referring now to the figures of the drawing in detail and first, particularly, to
This system is operated in that a vehicle 3 is moved along the track 11 from the first end station 1 to the middle station 1b by means of the conveying cable 21. As the procedure continues further, this vehicle 3 is coupled to the second conveying cable 22, which moves it to the second end station 1a. As the procedure continues, this vehicle 3 is moved along the track 12 from the second end station 1a to the middle station 1b and from that to the first end station 1. Similarly, the other vehicles 3 are also moved along the track 11 between the end stations 1 and 1a and the middle station 1b by means of the conveying cables 21 and 22 in a first direction, and along the track 12 by means of the conveying cables 23 and 24 in the opposite direction. Since the individual vehicles 3 are in each case coupled only to one of the conveying cables 21 to 24, they are moved individually by the drives 25 for the conveying cables 21 to 24. Thus, they are stopped if the respectively associated drives 25 are stopped, whereupon passengers can get on or off.
Because any desired number of conveying cables, to which in each case a vehicle 3 or a group of vehicles may be coupled, is provided mutually successively on each section, it is possible to provide in the system on the one hand a number of vehicles 3 or groups of vehicles that corresponds to the number of conveying cables and the system may have any desired length.
In the case of known systems of this kind for conveying persons, coupling of the vehicles is transferred from one conveying cable to a successive conveying cable in that the mutually associated end regions of the conveying cables are located next to one another and the respective clamping device that is provided on the vehicles may be moved transversely to the course of the conveying cables. Here, coupling is transferred from one conveying cable to the successive conveying cable by uncoupling the vehicle concerned from a conveying cable by opening the clamping device, thereupon moving the clamping device such that it reaches the further conveying cable, and thereupon putting the clamping device in its closed position, as a result of which this vehicle is coupled to the further conveying cable. Thus, for operation of a system of this kind it is necessary for each of the vehicles to be constructed to have a movable clamping device.
By contrast, in a system according to the invention for conveying persons, servo devices are provided for the runs of the conveying cables, as a result of which in the coupling regions the conveying cables are guided into the clamping devices located on the vehicles, which are in their open position. Thus, there is no necessity for the coupling clamps to be constructed such that they are movable transversely to the direction of movement of the vehicles.
As can be seen from
Similarly, the cable run 21a may be moved into this central position by means of the respectively other servo rolls 42.
As can be seen from
The cable runs are moved in at least approximately the horizontal or at least approximately the vertical direction.
As can be seen from
Each clamping device 6 has a clamping jaw 61 that is fixed to the bogie and a clamping jaw 62 that is movable. The movable clamping jaw 62, which is located on a servo lever 63, is moved into its open position by a fixed hydraulic or pneumatic servo cylinder 64 by way of a servo lever 65, a servo roll 66 and two servo arms 67 and 68, in opposition to the action of a pressure spring 69 which puts the clamping jaws 61, 62 into their closed position.
Instead of the servo cylinder 64, an electric servo motor may be provided.

The servo frame 71 is constructed to have two prolonged portions 74 and 75 which project toward the clamping device 6 and are constructed to have shoulders 74a and 75a on mutually facing side faces. These shoulders 74a and 75a serve to grasp one of the two cable runs 21a and 22a and guide it into the clamping jaws 61 and 62, which are in their open position. In this embodiment too, the clamping device 6 is operated by means of the servo cylinder 64 which is illustrated in
