Definitions

  • the invention relates to a method for monitoring a disembarking place for drag lifts, which is divided into three successive monitoring zones, the first of which forms an entry zone, the second an exit zone and the third a delimitation zone, monitoring signals being transmitted from sensors to central evaluation electronics, and if the transmitted signal sequence deviates from a signal sequence predetermined for the evaluation electronics, the drag lift drive is switched off, and a monitoring device for carrying it out.
  • Such a device has become known from DE-A-2516777, in which scanning beams, in particular modulated light beams, and interruptions of the beams by sensors detecting obstacles are used to monitor the alighting area. Furthermore, it is known from DE-A-2558695 to use a television camera to monitor the alighting area, which scans a patterned or striped control surface, changes in the pattern of the control image being detected by obstacles.
  • the invention has now set itself the task of creating a method and a non-disruptible monitoring device for the disembarking place of drag lifts, so that an operator can be effectively relieved.
  • this is achieved in that a magnetic field is assigned to each drag lift bracket, and the movement path of each occupied drag lift bracket is monitored by means of magnetic field sensors from the entry into the entry zone at least until the exit from the boundary zone.
  • the method according to the invention is therefore primarily able to monitor the timely release of the occupied stirrups as an essential prerequisite for the clearing of the disembarking place by the transported skiers, so that the operator is effectively relieved.
  • the magnetic field is used to monitor the correct sequence of movements of the occupied tow lift bracket Ordered sensors along its path of movement, ie in the entry zone in the ground or possibly also in a ground clearance corresponding to its towing position to the side next to the lane, and in the boundary zone behind a bar grate usually provided there.
  • a supplementary implementation of the method can provide that additional monitoring of the entry zone and the exit zone is carried out by means of capacitive presence sensors which, when a t-bar is in the entry zone and a person is present in the exit zone, produce a disturbance signal causing a deviation in the signal sequence.
  • a presence signal from the alighting zone only represents an interference signal when there is an entry signal from the entry zone, skiers can easily enter the disembarkation zone remain as long as subsequent drag lift bars are unoccupied.
  • the disembarking zone must only be cleared when a manned drag lift bracket enters the entry zone.
  • the top station of a drag lift (FIG. 1) has a rope deflection disk 18 for the tow rope 19, on which the hangers 9 of the drag lift bracket 11 are clamped at intervals.
  • the end of the drag lift route is formed, for example, by a slatted frame 22, behind which a conventional safety line can be stretched for switching off.
  • a conventional button 24 for switching off the lift system is provided at a suitable point.
  • the alighting area 1 is divided into monitoring zones and comprises at least one entry zone 2, one alighting zone 3 and one delimitation zone 4.
  • FIG. 3 shows an advantageous zone division for an alighting area with an exit on both sides.
  • a first magnetic field sensor 10 is arranged in the snow or in the ground 7 under the lane, possibly also laterally at the level of the occupied t-bar 11 (FIG. 2).
  • the magnetic field sensor 10 responds to a permanent magnet 12 (FIG. 4) that each drag lift bracket 11 is provided.
  • the first magnetic field sensor 10 is used to monitor whether the drag lift bracket 11 is occupied by skiers, since only then does the permanent magnet 12 pass the detection range of the first sensor 10, and thus to activate the monitoring device.
  • a speed sensor 13 (FIG. 5) is provided in the entry zone 2 in the area of a rope pulley 15 of the last lift support 16. This detects the speed of the pulley 15 and thus the driving speed of the drag lift.
  • the speed sensor 13 consists of a proximity switch 14 in which a signal is triggered by at least one pin 17 protruding eccentrically with each revolution of the pulley 15.
  • the signals are proportional to the driving speed and define the time intervals to all further monitoring signals, which must be emitted by further sensors until the exit place 1 if a occupied lifting bracket 11 is detected by the first magnetic field sensor 10.
  • Additional magnetic field sensors can be provided in the floor up to the exit area.
  • a necessary magnetic field sensor 10 is arranged behind or under the inclined grate 22 or at the end of the alighting area 1, with the aid of which it is monitored whether the bracket is released in time in the alighting zone 3 within the intended travel route. If a skier is caught on the bracket 11, the latter retracts late and passes the bar grating 22 with a delay.
  • a last sensor 10 which can also be a magnetic field sensor, can also be provided at a point near the deflection plate 18, at which the bracket 11 must be completely retracted into the hanger. If a magnetic field sensor is used, its arrangement can be based on a mast 23 according to FIG. 4. If the bracket 11 passes too low, the last sensor 10 does not respond and the drag lift drive is switched off.
  • Another device can also be used as a sensor at this point, for example a touch switch, which responds to a tow lift bracket 11 that has not yet calmed down.
  • a central evaluation electronics processes all signals coming from the individual sensors and compares them with the given signal sequence, switching off the lift drive in the event of deviations.
  • the assigned process computer is freely programmable.
  • the control of the movement path between entry and exit is switched to inactive, presence signals from the presence sensor 20 in the exit zone 3 being ignored. However, the presence signal from the exit zone 3 is taken into account if it is still present at the next entry signal.
  • An intercom system can be provided so that announcements and instructions can be given to the disembarkation point 1 from the embarkation point. If there is a presence signal from the limiting zone 4, the drive is switched off if either the magnetic field sensor 10 below the grating 22 has not emitted an exit signal or if there is a new entry signal from the entry zone 2.
