Definitions

  • the present invention relates to a driving device for attachment to a cable of a cable car, a cable car comprising at least one driving device, a method for damping the deflection of a driving device of a cable car and the use of a driving device.
  • the driving resources of a cable car system are known.
  • a device for attaching a driving device to a cable car system on a hanger rod is known.
  • the cabin is suspended with two legs on a hanger rod.
  • Such a device has the disadvantage that the cabin can begin to vibrate above a certain driving speed. This can happen, for example, by causing the driving equipment to swing due to gusts of wind or by moving the cable car's driving equipment over a cable car support and then being carried again by the cable.
  • These oscillations can become stronger if the excitation frequency essentially corresponds to the natural frequency and the oscillations are superimposed.
  • Vibrations can pose a danger to the occupants of the cable car or to people who are in the vicinity of the cable car.
  • conventional cable cars can only be operated at a certain maximum speed. Maintaining the maximum speed ensures that the vibrations not be reinforced and the cable car can be operated safely. The maximum speed leads to long transport times and a low transport performance of the cable car.
  • a driving device for attachment to a cable of a cable car system a cable car comprising at least one driving device, a method for damping the deflection of a driving device of a cable car and the use of a driving device according to the independent claims.
  • the cabin is connected to the connector through a connecting device.
  • the hanging rod of the cable car has an upper longitudinal distance from the cable holder to the joint.
  • the joint has a lower longitudinal distance from the connecting device.
  • the ratio of the upper longitudinal distance to the lower longitudinal distance is essentially less than 3.5.
  • the ratio of the upper longitudinal distance to the lower longitudinal distance can be between 2.5 and 3.2.
  • the ratio of the upper longitudinal distance to the lower longitudinal distance can also be between 2.7 and 3.1.
  • the upper longitudinal distance is greater than the lower longitudinal distance.
  • Such a vehicle can be operated safely and quickly without excessive vibrations.
  • the transport or travel time of a cable car that is operated with such a vehicle is therefore very short and users and/or goods can be transported extremely quickly and comfortably.
  • the hanging rod and the connector can be made of steel.
  • the hanging rod and the connector can also be made from a different alloy. It is also possible that the hanging rod and the connector have several materials or are made from a different material.
  • the coupling with the cable holder can be designed so that the cable is clamped by the coupling when the coupling is in a closed state. When the clutch is in an open state, the rope will not be pinched by the clutch.
  • the clutch can have tensioning elements such as springs, which are essentially relaxed when the clutch is in the closed state. By opening the coupling, for example in the station of a cable car, the springs of the coupling are tensioned and the cable holder opens. Without one external force, the clutch is therefore in a closed state.
  • the opening for receiving and clamping a rope is preferably designed so that the center of the rope corresponds to the center of the rope holder. This puts even pressure on the rope.
  • the cabin can be equipped with seating for users. It is also possible that the cabin is a cabin for material transport. It is also possible that the cabin is suitable for transporting passengers as well as for transporting goods.
  • the joint with which the connector is connected to the hanging rod can have a longitudinal axis.
  • the longitudinal axis can be essentially aligned in the transport direction of the vehicle. It is crucial that the connector and the hanging rod can move relative to one another.
  • the joint can be equipped with bearings.
  • the joint may have ball bearings and/or needle bearings and/or tapered roller bearings or other types of bearings.
  • the upper longitudinal distance can be in the range of 1 to 2.5 meters.
  • the lower longitudinal distance can be between 0.1 and 1 meter. What matters is the ratio between the upper longitudinal distance and the lower longitudinal distance.
  • the hanging rod and the cabin can be connected by one or more dampers.
  • the damper is then connected to the cab at a damper base point and the damper is connected to the hanger rod at a damper hang point.
  • the arrangement of the damper minimizes the likelihood of vibrations occurring that endanger the safety or comfort of the user.
  • the damper also ensures that the natural frequency with which the Driving equipment oscillates, differs clearly from an excitation frequency with which the driving equipment is excited to oscillate. This allows the driving equipment to be operated safely and quickly.
  • the damper can be a hydraulic damper. It is also possible that the damper is a spring. It is also possible that the damper has a combination of a hydraulic damper and a spring. Other types of dampers or combinations of different damping elements are also conceivable.
  • a first angular axis can run from the damper base point to the opening center.
  • a second angular axis can extend vertically from the damper base point when the cabin is at a standstill.
  • a damper longitudinal axis can run from the damper suspension point to the damper base point. The angle between the damper longitudinal axis and the second angular axis can extend in a range of +/- 3° to the bisector of the first angular axis and the second angular axis.
  • damper results in an advantageous interaction of the damper with the cabin and the hanging rod. It is ensured that the relationship between the braking/damping and the deflection of the cabin is such that the cabin does not tilt excessively and is nevertheless not braked too abruptly. In addition, there is an advantageous distribution of force in the damper and in the other components. This allows the driving equipment to be operated safely and quickly.
  • the driving equipment can be designed such that the damper base point is at a distance from the connecting device that is greater than a distance between the opening center and the second angular axis.
  • damper ensures that the cabin of the driving equipment is comfortably damped for users, that the cabin is not braked too abruptly and that the cabin is not deflected excessively.
  • the distance between the damper base point and the connecting device can be at least 5 cm greater than the distance between the opening center and the second angular axis.
  • the distance can also be at least 10 cm, 20 cm or more than 30 cm larger.
  • a cabin joint can be arranged between the connector of the driving equipment and the cabin.
  • Such an arrangement with a cabin joint results in an advantageous interaction between the hanging rod, the connector, the cabin and the damper.
  • the mobility of the driving equipment through the joint, the cabin joint and the damper results in a quick and comfortable transport process. This means that the driving equipment can be moved quickly and with little vibration.
  • the cabin joint can be a normal swivel joint. It can also be a ball joint.
  • the joint can have bearings such as needle bearings or ball bearings or tapered roller bearings. Other types of warehouses are also possible.
  • the joint can have a joint axis.
  • the joint axis can essentially be in the direction of travel of the vehicle get lost.
  • the longitudinal axis of the cabin joint can be designed parallel to the longitudinal axis of the joint.
  • the object of the invention is further achieved by a cable car comprising at least one driving device as described above and a rope.
  • Such a cable car can be operated quickly, safely and comfortably for users.
  • the cable car can have several means of transport.
  • the cable of the cable car can have a cable center that corresponds to the opening center.
  • the transport equipment can be connected precisely and safely to the rope of the cable car.
  • the hanging rod of the cable car has an upper longitudinal distance from the cable holder to the joint.
  • the joint has a lower longitudinal distance from the connecting device.
  • the ratio of the upper longitudinal distance to the lower longitudinal distance is essentially less than 3.5.
  • the ratio can also be in the range between 2.5 and 3.2.
  • the ratio can also be between 2.7 and 3.1.
  • the cable car's operating equipment is slowed down from a speed of more than 8 meters per second to a speed of less than 2 meters per second when entering the station.
  • the vehicle can also be braked from a speed of more than 9 meters per second. In particular, the vehicle is braked to a speed of less than 1 meter per second.
  • the driving equipment is preferably uncoupled from the rope during the process.
  • Such a method allows a cable car to be operated safely and ensures that the users of the cable car can get on and off at a station safely and comfortably and can be transported quickly on the open route of the cable car. Goods can also be transported quickly and can be safely loaded or unloaded in the station when the vehicle has braked.
  • the object of the invention is further achieved by using a driving resource as described above for entering a station at a speed of at least 8 meters per second, in particular at least 9 meters per second, further in particular at least 10 meters per second.
