Definitions

  • the present invention relates to a method for moving an elevator car of an elevator for evacuating passengers and a brake release device for moving an elevator car of an elevator for evacuating passengers.
  • the disadvantage here is that since the elevator car moves very slowly or not at all depending on the weight ratios between the counterweight and the elevator car with people, a large number of electrical impulses are necessary to move the elevator car appreciably. It can therefore take a very long time until the elevator car has been moved to a height at which the passengers can leave the elevator car. It is also disadvantageous that with such a method, if there are large differences in weight, the elevator system can reach a high speed within the time period and must be braked and brought to a standstill at the end of the time period. This leads to jerky movements which unsettle the passengers and possibly even endanger them.
  • a method for moving an elevator car of an elevator for evacuating passengers from the elevator car of the elevator in the event of a power failure by a brake blocking a vertical movement of the elevator car comprising the following steps: transmitting an electrical Power to the brake of the elevator for releasing the brake and releasing the vertical movement of the elevator car, wherein the brake can be moved and retained in a plurality of positions, which are between a fully closed position and a fully open position, depending on the transmitted electrical power; Determining an actual speed at which the elevator car is moving; Comparing the actual speed with a target speed; and setting, in particular increasing or reducing the electrical power which is transmitted to the brake as a function of a deviation of the actual speed from the setpoint speed, so that the actual speed essentially corresponds to the setpoint speed.
  • the advantage here is that the electrical power which is transmitted to the brake depends on an actual speed and a target speed.
  • the power that is transmitted to the brake determines the state, i.e. the position of the brake shoe and thus the braking force that the brake exerts on an object to be braked. Will there be enough electrical power to the brake transmitted, it opens from a closed position to an open position. On the way from the closed position to the open position, a large number of intermediate positions are passed through, i.e. the brake shoes are located in different positions in which they touch the brake disc or the shaft to different degrees and thus brake differently. In the closed position, the brake shoes press so hard against the object to be braked that the elevator does not move in height even when it is loaded with a nominal load.
  • the brake shoes are completely released from the object to be braked, so that even a small difference in weight between the elevator car and the counterweight causes the elevator to move under the action of gravitational force.
  • the positions can be used to regulate the speed of the elevator during evacuation. If the speed falls below a setpoint, the brake can be moved to an intermediate position, which is closer to the fully open position, and held there, as a result of which the braking effect decreases and the speed increases. If a target speed is exceeded, the brake can be moved from the current position in the opposite direction to the aforementioned and held in an intermediate position, which is closer to the fully closed state, whereby the braking effect is increased and the speed of the elevator system is reduced .
  • the braking effect is strongest in the fully closed position.
  • the braking effect decreases with every position which is closer to the fully open position (no grinding effect). If the power which is supplied to the brake is controlled as a function of the speed, then the speed can be set independently (at least within a certain weight spectrum) of the weight difference in the elevator system.
  • an evacuation of the elevator car can be achieved in which the elevator car is moved essentially at a constant speed and thus a feeling of comfort and safety can be achieved generated for the passengers in the elevator car in contrast to the evacuation process, in which abrupt braking processes take place at short intervals.
  • the elevator car can be evacuated without long waiting times, i.e. in a short time, without exposing passengers to a high risk, since the service technician starts the process by pressing a button and can then be sure that the car is being controlled, in particular is not moved at too high a speed.
  • the large number of acceleration / braking processes as are customary in the known methods, are bypassed without the safety of the passengers being endangered.
  • a brake release device for moving an elevator car of an elevator for evacuating passengers from the elevator car of the elevator in the event of a power failure in which a brake blocks vertical movement of the elevator car is proposed, the brake release device comprising: an electrical energy source for supplying the brake with energy, a semiconductor switch, in particular an IGBT for connecting the brake to the energy source, and a control device for controlling the switch.
  • an elevator for passengers comprising an elevator car for accommodating the passengers and a brake release device as described above and below.
  • the elevator car In the event of a power failure, the elevator car is usually braked or blocked by brakes, which are closed when there is no current, so that vertical movement along the elevator shaft is not possible as long as the brake is closed.
  • the brake To move the elevator car, the brake is released in the known methods by applying an electrical pulse to the brake once or several times, which completely opens the brake.
  • the brake typically remains in the fully open state, so that the elevator car can move freely, that is, without the action of the brake.
  • the lengths of the electrical pulses are the same, that is, each electrical pulse has the same length.
  • the elevator car begins to move and then moves under certain circumstances very slowly, so that the movement in height or the distance covered in height per electrical impulse is only very small.
  • the car can move at a very high speed and must then be braked sharply at the end of the electrical impulse in order to be brought to a standstill.
  • the elevator car is braked abruptly. Whether the car moves very slowly or quickly depends exclusively on the weight ratios between the elevator car and the counterweight. The possibly abrupt braking can put a heavy strain on the passengers in the elevator car.
  • the electrical power which is applied to the brake is set in such a way that the elevator car continues to travel at this setpoint speed after a setpoint speed has been reached. An evacuation is thus achieved in which the speed of the elevator car is essentially constant after a setpoint speed has been reached.
  • the electrical power that is transmitted to the brake is essentially regulated in such a way that the actual speed corresponds to a setpoint speed.
  • the brake is moved in the direction of the fully closed position by reducing the electrical power and, under the action of the springs, which completely closes the brake in the de-energized state, so that the brake shoes are more attached grind the object to be braked. This results in an increased braking effect.
  • the actual speed of the elevator system decreases and therefore approaches the target speed. If the actual speed is lower than the target speed, the electrical power which is transmitted to the brake is increased so that the brake opens further, i.e. moves in the direction of the fully open position, so that the grinding effect of the brake shoes decreases on the object to be braked and the elevator system can move faster with a low braking resistance.
  • the transmitted electrical power is also set by opening or closing a switch which connects the brake to an electrical energy source.
  • the electrical power can be switched on and off continuously of the switch can be checked. If the switch is switched on, the brake, in particular the electromechanical actuator of the brake, is electrically connected to the energy source, so that a current is established from the energy source to the brake. By turning the switch on and off, this current and thus also the electrical power that is transmitted to the brake is modulated.
  • the brake can assume any number of intermediate positions between the two end positions (completely closed and completely open). In these intermediate positions, the grinding force of the brake linings changes, so that a smaller or greater braking effect arises depending on the granted intermediate position. With a corresponding control of the switch it can thus be achieved that the elevator car moves at a constant speed, namely the setpoint speed.
  • the electrical power is also transmitted to the brake in the form of an electrical pulse, the transmitted electrical power being adjusted by increasing or decreasing a pulse width and / or pulse amplitude and / or pulse frequency of the electrical pulse.
  • the opening state of the brake can thus be set by a combination of one or more of the parameters mentioned above. If the pulse width and / or pulse amplitude and / or pulse frequency are controlled, this results in a simple way of adjusting the power transmitted to the brake.
  • the pulse width here is the length of a pulse, i.e. the period of time in which a certain voltage is applied to the brake. In the case of a voltage pulse, the pulse amplitude is the voltage value (in volts).
  • the pulse frequency is the reciprocal of the period in which a pulse is repeated.
  • the electrical pulse is a voltage pulse, in particular a DC voltage pulse.
  • the electrical pulse is a square pulse.
  • the method starts when a switch is actuated.
  • the evacuation can thus be started by a service technician who operates a switch. This enables the service technician to start the evacuation process only when the system is in a safe state that allows evacuation.
  • the method steps are repeated while a switch is actuated.
  • a switch To carry out the method, a switch must therefore be pressed constantly. This has the advantage that the evacuation can only be carried out under the supervision of a service technician can be carried out. The technician must operate the switch during the entire on-site procedure. A safety element is built into the evacuation and thus a safe evacuation is made possible.
  • the method is ended as soon as the car reaches a floor.
  • the method is automatically stopped when a floor is reached on which the passengers can be evacuated. It is thus made impossible that the evacuation operation can be continued after reaching the floor. This makes it impossible to miss the floor in the evacuation operation. This simplifies the evacuation process.
  • the transmission of the electrical power to the brake is stopped when a speed limit is exceeded, so that the brake is closed.
  • Such a method has an additional safety function in that the method is automatically terminated if too high a speed is detected. Since the actual speed has to be measured at regular intervals for the process, the implementation of such a safety function is possible without great additional effort. In this way, a safe method is achieved that is easy to implement.
  • the transmission of the electrical power to the brake is stopped when a speed limit is undershot, so that the brake is closed.
  • the brake release device comprises an electrical energy source for supplying the brake with energy, a semiconductor switch, in particular an IGBT, for connecting the brake to the electrical energy source, and a control device for controlling the switch.
  • the brake release device in this embodiment can connect / disconnect the brake to / from the power source at a high frequency by the presence of a semiconductor switch and a control device for controlling this semiconductor switch.
  • the flow of energy into the brake can thus be modulated by the switch-on behavior.
  • This allows the holding position of the brake to be set precisely by the brake release device according to the invention.
  • a semiconductor switch enables higher switching frequencies, which only enables the transmitted power to be modulated to achieve a large number of different braking positions in which the brake exerts different braking effects on the object to be braked, as described above.
  • the braking resistance of the brake which it exerts on the object to be braked, can be finely adjusted by checking the position of the brake shoes.
  • fine adjustment of the braking position and thus the braking effect it can be ensured in a technically simple manner that the elevator car does not reach or exceed excessive speed.
  • the speed of the Elevator car is kept essentially constant during the evacuation. Constant in this context is to be understood as meaning that the elevator car is moved at an essentially constant speed after an acceleration phase until a deceleration phase is initiated shortly before reaching the next floor, in which the elevator car moves from the essentially constant speed to zero -Speed, i.e. to a stop, is brought.
  • abrupt braking of the elevator car also leads to a reduction in the comfort of the passengers in the elevator car.
  • Another advantage of this embodiment of the brake release device is that the brakes for braking the elevator car are usually spared, since the forces that occur when braking the elevator car can be kept particularly low.
  • the brake release device further comprises a speed determination device for determining a speed of an elevator car.
  • the presence of a speed determining device enables the brake release device to regulate the speed in a closed control loop.
  • the brake release device can thus keep the speed of the elevator car essentially constant during the evacuation process.
  • the speed determination device comprises a magnetic reading device on the elevator car and a magnetic tape in the shaft.
  • the speed is determined by the Speed determination device, that is, determined by the magnetic reader, which reads out a magnetic field pattern along a magnetic tape.
  • the brake release device can thus determine the speed of the elevator car without a separate speed-determining device being required exclusively for the brake release device. This leads to a cost-effective design of the brake release device.
  • the speed determination device comprises an encoder on the machine of the elevator.
  • the speed of the elevator car can be deduced from the speed of rotation of the shaft of the machine.
  • an elevator for passengers comprising an elevator car for accommodating the passengers and a braking device, as described above and below.
