Description

The present invention relates to a system for transporting people with at least one lane, along which several vehicles or groups of vehicles can be moved by means of self-contained conveyor ropes, with at least two consecutive conveyor ropes being provided, each of which is assigned at least one drive, making them independent can be driven from one another and to which the vehicles or vehicle groups can be coupled by means of clamping devices.

Known such systems for the transport of people who, for example, from the EP 611220 B1 and the EP 1193153 B1 or the EP 0 461 098 A1 are known, have two lanes along which vehicles can be moved by means of self-contained conveyor ropes to which drives are assigned. Since the vehicles are coupled to the conveyor ropes assigned to them, the movement of the vehicles is controlled by the drives of the conveyor ropes. Since the length of these hoisting ropes is limited to a maximum of about 2000 m, it is also known to provide at least two self-contained hoisting ropes in each of the two directions of travel. This makes it possible, on the one hand, to design such systems for transporting people of any length. Since the vehicles are coupled to the individual conveyor ropes, this also makes it possible to control the movement of the individual vehicles independently of one another. By switching off the drive of one of the hoisting ropes, the vehicles coupled to this hoisting rope are brought to a standstill, so that passengers can get on or leave them.

In known systems of this type, when the vehicles are moving, it is necessary to uncouple them at the end of a conveyor rope located in the direction of movement and to couple them to the subsequent conveyor rope. In order to make this possible, it is known to arrange the end regions of the two conveyor ropes next to one another and, furthermore, to design the at least one clamping device provided on the vehicles to be transversely adjustable with respect to the direction of movement. As soon as the vehicle in question has reached the end of the first hoisting rope, it is uncoupled from the first hoisting rope, the clamping device is also adjusted transversely to the course of the two hoisting ropes and the vehicle is coupled to the subsequent hoisting rope, causing it to pass through this hoisting rope is moved.

The present patent application is based on the object of creating a system for transporting people in which it is not necessary to arrange two successive conveyor ropes next to one another in their end regions and to provide a transversely adjustable coupling device. According to the invention, this is achieved in that the at least two successive conveyor ropes are arranged in the longitudinal direction of the system, at least approximately in a line, that the vehicles are designed with at least two clamping devices spaced apart from one another in the longitudinal direction of the system, and that a control device is provided , through which at the transition of a vehicle from one hoisting rope to the following hoisting rope at least the first clamping device located in the direction of travel is uncoupled from the first hoisting rope and then coupled to the following hoisting rope and subsequently the at least one further clamping device is also uncoupled from the first hoisting rope and then attached the following hoist rope is coupled.

The control device is preferably formed by a control rail, by means of which the clamping devices located on it are brought into their open position when the vehicle moves, whereby the vehicle is uncoupled from the first hoisting rope and subsequently coupled to the following hoisting rope. The control rail can be designed with preferably wedge-shaped control ramps at both ends.

Furthermore, the two control ramps can preferably be pivoted and adjusted in height by means of adjusting devices.

Furthermore, each of the clamping devices is preferably assigned a control roller mounted on a control lever, which runs onto the control rail, whereby the clamping devices are brought into their open positions.

The vehicle is preferably brought to a standstill in the area of a control rail and the conveyor ropes are also stopped, whereupon control ramps are pivoted, whereby at least the first clamping device in the direction of movement of the vehicle is coupled to the conveyor cable and the following clamping devices are uncoupled from the first conveyor cable and becomes the following Conveyor rope driven, whereupon the other clamping devices are successively coupled to the following conveyor rope. Alternatively, the two hoisting ropes can be driven at the same speeds, the individual clamping devices being successively uncoupled from the first hoisting rope and being coupled to the following hoisting rope by moving the vehicle over a control rail.

Like this from the FIG. 1 to FIG. 4 As can be seen, a self-contained hoisting rope 1 and a second self-contained hoisting rope 2 following this approximately in a straight line are provided in a system according to the invention for transporting people. Such a system can have any number of successive hoisting ropes in each of the directions of travel.

The ends of the first hoisting rope 1 are laid over rope drums 10, which are rotatably mounted about an at least approximately horizontally aligned axis, the hoisting rope 1 having an upper run 11 and a lower run 12. The second hoisting rope 2 is placed at its ends over rope drums 20, which also around a at least approximately horizontally aligned axles are rotatably mounted, the second hoisting rope 2 also having an upper strand 21 and a lower strand 22. At least one of the cable drums 10 and 20 is assigned a drive, by means of which the two conveyor cables 1 and 2 can be moved. The two upper strands 11 and 21 of the two conveyor ropes 1 and 2 are guided over rope support rollers 13 and 23. By means of the two conveyor ropes 1 and 2, several vehicles 3 can be moved along a roadway. For this purpose, the vehicles 3 are designed with several clamping devices 31, 32, 33, 34 and 35 arranged at a distance from one another in the direction of movement, which can be coupled to the respective upper cable strands 11 and 21 of the hoisting ropes 1 and 2, whereby the vehicles 3 in the direction of the arrow A are movable. In the area of the transition of the vehicles 3 from the first hoisting rope 1 to the following hoisting rope 2, a device 4 for controlling the clamping devices 31 to 35 is also provided.

In the operation of such a system, when the vehicles 3 move from the first hoisting rope 1 to the second hoisting rope 2, the clamping devices 31 to 35 are opened one after the other, as a result of which they are uncoupled from the upper run 11 of the first hoisting rope 1 and become one after the other closed again, whereby they are coupled to the upper run 21 of the second hoisting rope 2, whereby the vehicles 3 are initially moved by the first hoisting rope 1 and then by the second hoisting rope 2.

At the in FIG.1 In the operating phase shown, the vehicle 3 is coupled to the upper cable run 11 of the first hoisting cable 1 by means of all coupling devices 31 to 35.

At the in FIG.2 The operating phase shown, the clamping devices 31 to 33 have been opened one after the other by the control device 4, whereas the clamping devices 34 and 35 are still coupled to the upper cable strand 11 of the hoisting cable 1.

At the in FIG.3 During the further movement of the vehicle 3, the clamping devices 31 to 34 were successively coupled to the upper strand 21 of the second hoisting rope 2 and the clamping device 35 was opened, whereby the vehicle 3 is coupled to the upper strand 21 of the second hoisting rope 2 and is uncoupled from the upper run 11 of the first hoisting rope 1.

At the in FIG.4 operating phase shown, all clamping devices 31 to 35 have been closed, whereby the vehicle 3 is coupled by means of all clamping devices 31 to 35 to the upper run 21 of the second conveyor rope 2 and is moved by this.

Instead of individual vehicles, vehicle groups can also be provided.

A first embodiment of a system according to the invention is explained in more detail below.

Like this from the FIG.5 and FIG.5a As can be seen, the system has a track 5, which is preferably formed by two rails and along which at least one vehicle 3 can be moved. For this purpose, a first hoisting rope 1 is provided, which at its end shown in the drawing is guided over a deflection drum 10 and over a deflection drum 10a. This first hoisting rope 1 is followed in a straight line by a second hoisting rope 2 which, at its beginning shown in the drawing, is guided over a deflection drum 20 and a deflection drum 20a. The two conveyor ropes 1 and 2 each have an upper rope run 11 and 21 and a lower rope run 12 and 22, respectively. The vehicle 3 is designed with pairs of clamping devices 31, 32, 33, 34 and 35, by means of which it can be coupled to the respective upper run 11 or 21 of the two conveyor ropes 1 and 2. To actuate the clamping devices 31 to 35, a control rail 4 is provided, at the two ends of which control ramps 41 and 42 are provided which can be pivoted about horizontal axes 43a and 44a by means of actuating cylinders 43 and 44 assigned to them.

When the system is in operation, the vehicle 3 is moved in the direction of arrow A in the area of the transition between the two conveyor ropes 1 and 2. Control rollers of the clamping devices 31 to 34 run successively over the first control ramp 41, which is in its lower pivot position, onto the control rail 4 and onto the second control ramp 42, which is in its upper pivot position, whereby the clamping devices 31 to 34 are brought into their open position and held in this, whereas the clamping device 35 remains coupled to the first hoisting rope 1. In this position of the vehicle 3, the first hoisting rope 1 is stopped.

This is the position which is in the FIG.5 and FIG.5a is shown.

Subsequently, the second control ramp 42 of the control rail 4 is pivoted into its lower pivot position, whereby the clamping devices 31 move from their open position to their closed position, whereby the vehicle 3 is coupled to the second hoisting rope 2, which is also not moved. This position is in the FIG.6 and FIG.6a shown.

The first control ramp 41 is then pivoted into its upper position, as a result of which the clamping devices 35 are also uncoupled from the first hoisting rope 1. This position is in the FIG.7 and FIG.7a shown.

As soon as the second hoisting rope 2 is driven again, the vehicle 3 is moved further in the direction of the arrow A. Thereupon the clamping devices 32 to 35 also successively move into their closed position, whereby the vehicle 3 is also coupled to the second hoisting rope 2 by means of the clamping devices 32 to 35. In the FIG.8, FIG.8a and FIG.8b The second embodiment shown, the control rail 4 is formed at its beginning and at its end with fixed control ramps 41 and 42, by which the pairs of clamping devices 31 to 35 are controlled by the movement of the vehicles 3 over the control rail 4. Here the two Conveyor ropes 1 and 2 driven at the same speed, the vehicle 3 being moved at the speed of the two conveyor ropes 1 and 2 during the transition from the first conveyor cable 1 to the second conveyor cable 2. When driving over the control rail 4, the clamping devices 31 to 35 are successively brought into their open position by the first control ramp 41, whereby they are uncoupled from the first hoisting rope 1, and they are held in the open position by the control rail 4. As soon as they come into the area of the second control ramp 42, they are brought back into the closed position, as a result of which the vehicle 3 is coupled to the second hoisting rope 2.

In this embodiment it is imperative that the two conveyor ropes 1 and 2 are moved synchronously. In this embodiment too, the vehicle 3 can be stopped by switching off the drives for the hoisting ropes 1 and 2 in order to enable the passengers to get on or off.

In the FIG.9 and FIG.9a In the area of the transition from the first hoisting rope 1 to the second hoisting rope 2, at least one conveyor device 6 is provided by means of which the vehicle 3 is not yet connected to the second hoisting rope 2 at the stage in which it is uncoupled from the first hoisting rope 1 and not yet connected to the second hoisting rope 2 is coupled, as long as it is moved in the direction of arrow A until it is coupled to the second hoisting rope 2. The conveying device is formed by two drive motors 61, by which at least one drive roller 63 is driven via wedge rims 62 and comes into effect on a drive surface 64 of the vehicle 3.

Like this from the FIG.10 and FIG.10a As can be seen, the clamping devices 31 to 35 located on the vehicle 3 are designed with a control lever 7 on which a control roller 71 is mounted. The control roller 71 is under the action of a compression spring 72, by means of which the clamping devices 31 to 35 are brought into their closed position. As soon as the control roller 71 runs onto the control rail 4, the control lever 7 is adjusted against the compression spring 72 so that the clamping devices 31 to 35 reach their open position, whereby the vehicle 3 is uncoupled from the conveyor ropes.

The vehicle 3 is designed with a vehicle frame 81, with running wheels 82 which roll on rails 51 and 52 of the roadway 5, with guide rollers 83 and with damping elements 84.
