Definitions

  • the invention relates to an operating method for an elevator with two elevator cars and a counterweight according to the preamble of the independent claim.
  • Such lifts are for example from the EP 1 329 412 A1 known.
  • the elevator system described there has two elevator cars in a common elevator shaft, each with a drive and with a common counterweight.
  • the object of the present invention is to further improve an elevator system described above.
  • the inventive operating method is for an elevator with at least three elevator bodies, which can be moved along at least one roadway and via carrying and / or traction means are connected to each other.
  • the first and the second elevator body are suspended by means of the carrying and / or traction means 1: 1 and the third elevator body is suspended by means of the carrying and / or traction means 2: 1.
  • At least one of the three elevator bodies can be blocked by means of a controllable blocking device. When passengers are transported in a first of the three elevator bodies, a second elevator body is blocked. If there is an imbalance between the weights of the two unblocked elevator body, the first elevator body is moved to an evacuation position.
  • the evacuation position is preferably an evacuation floor in which trapped passengers leave the elevator body.
  • Another possible evacuation position is located at the upper or lower shaft end, the passengers rise, for example, a maintenance, ventilation, window or roof opening from the drawer.
  • the evacuation position can be any position in the shaft in which the passengers get out of the elevator body or elevator.
  • the advantage of the operating method is that after the motors have failed, an elevator car with passengers can continue to be moved immediately to an evacuation floor with the aid of the gravitational force. Trapped passengers thus arrive quickly and comfortably on an evacuation floor on which they can leave the elevator car. So no service people are needed to evacuate the passengers from the elevator car and unpleasant waiting times are largely avoided.
  • the operating method passengers are transported in the first and second elevator bodies.
  • the third elevator body is blocked and one of the other elevator bodies is moved into an evacuation position according to a determinable criterion in the event of an imbalance between the weight masses of the two unblocked elevator bodies.
  • the criterion includes e.g. at least one of the following criteria: less distance to the evacuation position, higher number of passengers, or presence of a passenger over which an identity profile is detected.
  • the elevator has an elevator control, which is preferably in communication with different system elements of the elevator.
  • system elements are e.g. a hoistway information system that generates, among other things, information about the car positions in the hoistway, a weight gauge that measures the current payload weight of an elevator car, an image capture device that monitors the interior or access room of an elevator car, or an access control unit, e.g. assigns an identity to an arriving passenger.
  • the advantage of the operating method is that, depending on the situation, optimal evacuation of the passengers of an elevator body takes place. If the situation requires, for example, the passengers of an elevator body to be evacuated particularly quickly, the passengers are evacuated from that elevator body which has the shortest travel distance to an evacuation position. Accordingly, the elevator controller compares the travel distance of the elevator cars to one based on information of the hoistway information system, in particular the position of the elevator cars in the hoistway Evacuation position and prioritized the evacuation of the elevator car with the shortest driving distance in the evacuation position.
  • the lift body in which there are more passengers can also be moved to an evacuation position in a targeted manner. Because in this elevator body, the space of the elevator body per passenger is smaller. Thus, waiting times in such an elevator body are particularly unpleasant for the passengers and the occurrence of panic reactions is above average. In addition, a larger number of passengers can be evacuated faster.
  • the elevator control Prioritizing the evacuation of an elevator car on the basis of the number of passengers, the elevator control preferably takes on the basis of a measurement of the loading weight by the weight measuring device, the detection of the number of passengers by the image acquisition device or the identification of the passengers by the access control unit.
  • the elevator control compares the identity profiles of the passengers detected by the access control unit and prioritizes the evacuation of that elevator car in which a passenger with a corresponding identity profile resides.
  • an evacuation position is determined by a control unit, preferably the elevator control.
  • a position along the roadway of an elevator car is suitable as an evacuation position, for example, based on the following criteria: spatial proximity to the elevator car to be evacuated, distance to building exits, availability of escape routes for leaving a building, safety aspects such as a fire or violent acts of rioters. and other situation-specific criteria.
  • the control unit has information collected from various systems of the elevator communicating with the control unit: a hoistway information system which reports the positions of the hoistcars to the control unit, surveillance cameras, infrared sensors, fire detectors or other building-side installations, the information for the availability of escape routes from the building or for the safety of passengers on one floor or a storage unit allocated to the control unit which has stored the position of floors and building exits.
  • a hoistway information system which reports the positions of the hoistcars to the control unit, surveillance cameras, infrared sensors, fire detectors or other building-side installations, the information for the availability of escape routes from the building or for the safety of passengers on one floor or a storage unit allocated to the control unit which has stored the position of floors and building exits.
  • an upper elevator body has a lowerable weight.
  • the lowerable weight is lowered onto a lower elevator body to effect a weight force difference between a first and second unblocked elevator body.
  • a lower elevator body can also have a lowerable weight, which is lowered onto the shaft bottom.
  • a weight force difference between a first and second unblocked elevator body is also brought about.
  • an elevator body preferably an elevator car, is equipped with a winch. This winch is arranged in the lower region of one of the elevator bodies. A suspension on which the weight is suspended is on the winch rolled up.
  • the winch is equipped with a motor, preferably an electric motor, to roll up or down the suspension means, lifting or lowering the weight attached thereto.
  • the winch motor has a manual mode operable from the interior of an elevator car.
  • the winch is controlled or regulated by a control unit, preferably the elevator control.
  • the winch sensor means that provides the control unit, for example, information about the suspension medium voltage or the torque of the motor.
  • the control unit accesses information of a shaft information system with information about the position and speed of the elevator cars and calculates therefrom, the length of the carrier to be unrolled.
  • the advantage of the lowerable weights in the operating method is that, regardless of the weight distribution of the different elevator bodies, an imbalance, which is necessary for moving the elevator bodies into an evacuation position, can always be brought about.
  • the elevator has an emergency power unit to ensure power for carrying out the operating procedure.
  • the emergency power unit is preferably a battery or an emergency generator. It supplies the elevator control system and the elevator systems involved in the operating method, such as holding brakes, cabin brakes, blocking units, information and display means, cabin and shaft doors and possibly the electric motor of the winch of the lowerable weight with power.
  • the advantage of the existing emergency power unit is that the operating method is feasible even in the event of a power failure.
