Definitions
- the invention relates to a tensioning device for conveyor ropes of cable cars and drag lifts with a measuring device for the force with which the conveyor rope is tensioned, and a control device for driving the tensioning device, the drive of the tensioning device being actuated by the control device such that the Basic tension in the hoisting rope is kept constant.
- Conveyor rope is tensioned by measuring the rope tension force in the tension rope.
- a tensioning device of the type mentioned at the beginning as with a weight tensioning device and with a hydraulic one
- Tensioning device of the known type only possible to keep the basic tensioning force constant in the conveyor cable in the tensioning station, that is to say in the station with a movable drive or deflection disk.
- the measuring device for the clamping force is arranged in the opposite station (station with the fixed drive or deflection disc).
- This arrangement differs fundamentally from previously known tensioning devices in that, in the tensioning station, the conveyor cable is tensioned by the tensioning device with a variable tensioning force which is dependent on the loading condition of the cable car or the drag lift.
- An advantage of the invention is that the station in which the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning (course of the rope tensioning forces, size and location of the occurrence of the largest and smallest rope tensioning forces) with a fixed drive or deflection sheave can be.
- This can be an operational requirement for chairlifts with a disc exit, for example, or at least an operational advantage, e.g. for chairlifts with window entry.
- structural or topographical conditions for example a size of a station location that is too small for a tensioning station with regard to the required tensioning path, can make the use of the tensioning device according to the invention appear advantageous.
- Another advantage of the invention is that in that station in which the basic tensioning force of the conveyor rope is to be kept constant for reasons of rope dimensioning, no energy supply for one
- Clamping device of the type mentioned is required.
- the invention becomes particularly important if the top station is designed as a tensioning station and the bottom station is designed as a counter station, the conveyor cable being driven in the top station.
- the measuring device according to the invention in the valley-side counter station of the cable car technology, known, favorable case can be simulated, according to which the drive in the mountain station with a fixed drive pulley and the cable tension in the valley station take place with the aid of a weight tensioning device.
- this avoids the disadvantage of the movable deflection plate in the valley station, which is an issue when entering the valley station.
- the complex structural measures for the weight tensioning device which disturb the landscape, can be dispensed with.
- the invention can also achieve significant advantages if the valley station is designed as a tensioning station and the mountain station as a counter station, the conveying cable being driven in the valley station. This corresponds to the conventional, from course of
- Rope tensioning forces also favorable arrangement of the drive in the valley station via a fixed drive pulley and the rope tension in the mountain station with the help of a movable deflection pulley and a weight tensioning device.
- this case is particularly advantageous for mountain and valley transportation.
- realizing this case according to the invention by arranging the measuring device in the mountain-side counter station brings the additional advantage of a fixed deflection plate in the mountain station, which in particular offers the possibility of using a small mountain-side station location.
- the rope tension can expediently be carried out with the aid of a rope winch, the electric drive motor of which is controlled by the control device.
- the advantage of a winch tension lies in the tension path that can be freely selected within wide limits, while a hydraulic tensioning device has a narrower stroke limitation.
- the motor of a tension cable winch operates in intermittent operation, so it is not permanently loaded, in contrast to the hydraulic pump of a hydraulic tensioning device that is usually in continuous operation.
- the invention is not limited to a tensioning device with a tension cable winch, but comprises e.g. also hydraulic clamping devices.
- Fig. 1 shows in schematic form in plan view a cable car or drag lift system to illustrate the inventive principle of the solution
- FIGS 2 and 3 show two different chairlift systems in side view, also schematically simplified, to illustrate two preferred implementation solutions.
- the tensioning station 1 In the tensioning station 1 is the drive or movable in the longitudinal direction of the cable car or the drag lift Deflection pulley 2 for the conveyor cable 3 is connected to an electric motor driven cable winch 5 via a tensioning cable 4.
- a force measuring device 7 arranged in the counter station 6, the tensioning force in the conveyor cable is measured on the fixed drive or deflecting pulley 8.
- the cable winch in the tensioning station is actuated in such a way that the basic tensioning force of the conveyor rope on the fixed drive or deflection pulley of the opposite station is kept constant.
- the electronic control device 9 consists essentially of an amplifier which amplifies the signals from the measuring device and a servo relay which compares the setpoint and actual value of the clamping force and controls the contactors of the winch motor with a delay (e.g. 4 to 5 seconds) with a delay.
- a safety shutdown device can be provided, by means of which the system switches off in the event of certain deviations in the clamping force from the nominal value, e.g. with deviations of ⁇ 15%.
- the force measurement in the force measuring device 7 can e.g. with the aid of strain gauges arranged on the axis of the deflection disk 8, or other resistance sensors or with capacitive or inductive sensors.
- FIG. 2 illustrates a particularly advantageous application of the principle of the solution according to the invention on a chairlift in terms of cable car technology.
- the mountain station is designed as a tensioning station 1 with a movable drive pulley 2.
- the drive motor 10 of the conveyor cable 3 is also arranged in the mountain station.
- the valley station is provided as a counter station 6 with a fixed deflection plate 8.
- the rope tension in the mountain station is done by the tension rope 4 with the help of the winch 5.
- the Electric motor 11 of the cable winch 5 is switched by the control device 9, which is connected to the force measuring device in the opposite station 6.
- the valley station of a chair lift is designed as tension station 1.
- the conveyor cable 3 is also driven in the valley station, with the aid of the drive motor 10 which drives the movable drive pulley 2.
- a tension rope 4 with winch 5 is again provided, which is operated by the electric motor 11.
- the electric motor is switched via the control device, which is connected to the measuring device 7 for the tensioning force of the conveyor cable 3, the measuring device 7 being arranged in the top station, which is designed as a counter station 6 with a fixed deflection disk 8.
