Definitions

  • the present invention relates to a method for moving an elevator car of an elevator for evacuating passengers and a brake opening device for moving an elevator car of an elevator for evacuating passengers.
  • EP 3 216 735 A1 a method of gradually releasing the brake on an elevator car after a power failure to move the elevator car to a floor.
  • the electrical impulses for releasing the brake always have the same size or duration, for example a duration of 270 ms at intervals of 1000 ms.
  • 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 in which a brake blocks a vertical movement of the elevator car comprising the steps of: applying a electrical impulse or multiple electrical impulses to the brake of the elevator car to release the brake and enable the vertical movement of the elevator car, the brake being released as long as the respective electrical impulse is applied to the brake; Determination of a covered height (difference formation in relation to the height of the elevator car at the beginning of the application of the electrical impulse), which the elevator car has covered during and thus since the beginning of the application of the respective electrical impulse; comparing the determined altitude traveled to a predetermined distance; and terminating the application of the respective electrical pulse to the brake when the determined height traveled is equal to or greater than the predetermined distance.
  • the advantage of this is that typically the duration or time span of the electrical impulse to open the brake during which the brake is opened is not a predetermined time duration or span of time, but rather the duration or span of time of the electrical impulse or the application of the electric Impulse to the brake is variable and depends on the distance covered by the elevator car in height (ie along the elevator shaft).
  • the elevator car can move with people or passengers the same distance during the application of the electrical impulse for releasing the brake, regardless of the weight ratios between the counterweight and the weight of the elevator car. Consequently, the elevator car can usually be moved by a significant distance with a particularly small number of electrical impulses and moved to a level or a height at which the people or the passengers can safely leave the elevator car (e.g. at height one floor).
  • the comfort for the passengers in the elevator car typically increases, since the number of brake openings and brake closings is reduced.
  • the passengers can be evacuated from the elevator car within a short time.
  • the effort involved in evacuating the passengers from the elevator car typically decreases.
  • a brake opening 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 a vertical movement of the elevator car
  • the brake opening device comprising: a pulse generating device for Applying one or more electrical impulses to the brake of the elevator car to release the brake and enable the height movement of the elevator car, the brake being released as long as the respective electrical impulse is applied to the brake, and a determination device for determining a height traveled by the elevator car , which the elevator car has covered during the application of the respective electrical impulse, and for comparing the determined height with a predetermined distance, the brake opening device being designed in such a way that the application of the j respective electrical impulse to the brake is terminated when the determined distance traveled is equal to or greater than the predetermined distance.
  • an elevator for passengers comprising an elevator car for accommodating the passengers and a brake opening device as described above.
  • the elevator car is usually braked or blocked by one or more brakes that are closed when there is no power, so that a vertical movement along the elevator shaft is not possible as long as the brake or brakes is or are closed.
  • the brake or the brakes In order to move the elevator car, the brake or the brakes is or are thus released in that an electrical impulse is applied to the brakes once or several times, which opens the respective brake. During the electrical impulse, the brake typically remains in the open state, allowing the elevator car to move.
  • the lengths of the electrical pulses are the same, i.e. each electrical pulse has the same length.
  • the elevator car moves very slowly under certain circumstances, so that the movement in height or the distance covered in height per electric impulse is only very small. Therefore, in the prior art, moving a significant distance (e.g., a few centimeters or a few tens of centimeters) may take a very long time. Consequently, with conventional approaches, it may take a very long time before the elevator car has been moved to a level or a height at which the passengers can safely exit or be evacuated from the elevator car after the door or doors have been opened.
  • the distance covered along the elevator shaft or along the height is a termination criterion for ending the application of the electrical pulse or the opening of the brake.
  • ending criterion for covering the specified distance there can be other ending criteria for ending the application of the electrical pulse to the brake, which may occur earlier than the ending criterion for covering the specified distance.
  • a speed of the elevator car is also determined during the vertical movement during the application of the respective electrical impulse, the speed of the elevator car is compared with a predetermined speed, the application of the respective electrical impulse to the brake being terminated when the specific speed is equal to or greater than the specified speed.
  • reaching or exceeding a predetermined speed can be a further criterion for terminating the application of the electrical pulse to the brake.
  • the application of the electrical pulse to the brake can thus be terminated as soon as either the specific distance has reached or exceeded the predefined distance or the specific speed has reached or exceeded the predefined speed.
  • a period of time since the application of the respective electrical impulse to the brake to release the brake is also determined, the specific period of time is compared with a predetermined period of time, the application of the respective electrical impulse to the brake being terminated when the certain period of time is equal to or greater than the predetermined period of time.
  • the elapse of a predetermined period of time can be another criterion for terminating the application of the electrical pulse to the brake.
  • the application of the electrical pulse to the brake can thus be terminated as soon as either the specific distance has reached or exceeded the predefined distance or the specific time period has reached or exceeded the predefined time period. It is possible that the application of the electrical pulse to the brake is terminated as soon as either the specific distance has reached or exceeded the predefined distance or the specific speed has reached or exceeded the predefined speed or the specific period of time has reached or exceeded the predefined period of time .
  • the advantage of this is that the elevator car is typically not moved in one piece or uninterruptedly for too long. This tends to increase the comfort of the passengers in the elevator car, who might otherwise get the impression that the brake has failed, which could create anxiety among the passengers.
  • the electrical pulse is a square-wave pulse.
  • the electrical pulse can always have its maximum value or its minimum value. Values in between can generally only occur for a short period of time.
  • the electrical pulse is a voltage pulse.
  • the electrical pulse can have an increased voltage value (e.g. a high voltage for opening the brake compared to a low voltage or zero voltage for closing the brake).
  • the electrical impulse can thus include the application of an increased voltage to the brake.
  • the brake can usually have a particularly simple technical design.
  • the electrical impulse can usually be generated technically in a particularly simple manner.
  • the electrical pulse is generated by a controller, in particular a microcontroller.
  • a controller can apply the electrical pulse to the brake or a controller can generate the electrical pulse.
  • One advantage of this is that the electrical pulse can generally be generated technically in a particularly simple and reliable manner.
  • the brake opening device is designed to determine a speed of the elevator car during the vertical movement during the application of the respective electrical impulse and to compare the determined speed of the elevator car with a predetermined speed, the brake opening device being designed in such a way that the application of the electrical Pulse to the brake is terminated when the determined speed is equal to or greater than the predetermined speed.
  • the brake opening device can have a further termination criterion for the application of the electrical pulse to the brake.
  • the application of the electrical pulse can be terminated when either the determined distance is equal to or greater than the predetermined distance or the determined speed of the elevator car is equal to or greater than the predetermined speed.
  • a speed of the elevator car that is too high when the application of the electrical impulse is ended can typically lead to high negative accelerations when the elevator car is braked. Under unfavorable circumstances, these can adversely affect the comfort or health of the passengers in the elevator car.
  • a further advantage of this embodiment of the brake opening 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 opening device is designed to determine a period of time since the application of the respective electrical impulse to the brake to release the brake and to compare the determined period of time with a predetermined period of time, the brake opening device being designed in such a way that the application of the respective electrical pulse to the brake is terminated when the specific time period is equal to or greater than the predetermined time period.
  • the brake opening device can end the application of the electrical pulse to the brake as soon as either the specific distance has reached or exceeded the predefined distance or the specific period of time has reached or exceeded the predefined period of time. It is possible for the brake opening device to stop applying the electrical impulse to the brake as soon as either the determined distance exceeds the predetermined distance has reached or exceeded or the specific speed has reached or exceeded the predefined speed or the specific time period has reached or exceeded the predefined time period.
  • the advantage of this is that the elevator car is generally not moved in one piece or uninterruptedly for too long by the brake opening device. This tends to increase the comfort of the passengers in the elevator car, who might otherwise get the impression that the brake has failed, which could create anxiety among the passengers.
  • the electrical pulse is a square-wave pulse.
  • the electrical pulse can have the shape of a rectangle, i.e. the value of the electrical pulse can have either its maximum value or its minimum value or zero.
  • the brake or the material of the brake can generally be protected, since the brake is completely open when the electrical impulse is applied.
  • the electrical pulse is a voltage pulse.
  • applying the electrical pulse may include increasing the voltage applied to the brake.
  • the electrical impulse can thus have an increased voltage.
  • the brake can usually have a particularly simple technical design.
  • the electrical impulse can usually be generated technically in a particularly simple manner.
  • the pulse generating device includes a controller, in particular a microcontroller.
  • the electrical pulse can be generated by a controller or microcontroller.
  • the electrical pulse can typically be generated technically in a particularly simple and reliable manner.
  • the brake opening device can usually be designed particularly cost-effectively.
  • the controller or microcontroller is often present anyway for other tasks in the control of the elevator.
  • the distance covered by the elevator car during the respective electrical impulse can be determined or measured in different ways.
  • the distance can be determined by means of a magnetic tape with position information, the magnetic tape running along the height of the elevator shaft.
  • the height position of the elevator car can be determined by reading the information on the magnetic tape at the respective height at which the elevator car is currently located.
  • the distance or height covered since the application of the electrical impulse can be determined by forming the difference between the height at the beginning of the application of the electrical impulse and when the application of the electrical impulse has ended.
  • a further possibility for determining the distance or height covered is for the height of the elevator car to be determined by laser measurement or laser distance measurement.
  • the elevator car can have one or more laser devices for emitting a laser beam in the direction of the floor of the elevator shaft and/or in the direction of the ceiling of the elevator shaft.
  • the height of the elevator car or the distance of the elevator car from the floor or the ceiling can be determined by means of transit time measurement and/or interference.
  • the height or distance covered during the application of the electrical impulse can be determined by forming the difference in relation to the height of the elevator car at the beginning of the application of the electrical impulse.
  • the distance covered can be determined with a particularly high level of certainty and reliability. This means that there can be several checking levels or processes, so that the distance covered or the height of the elevator car can be determined with a particularly high degree of reliability. Errors in determining the height or the distance covered can thus essentially be ruled out.
  • the speed of the elevator car can be determined or measured in different ways. For example, the speed can be determined using the determined distance per unit of time (e.g. distance per second). It is also conceivable that the speed of the elevator car along the height is determined via the rotational speed of a disk or the like for moving the elevator car in height. The speed can also be determined using particularly reliable means. The specific speed can thus have a particularly high level of reliability.
  • the length of time since the respective electrical pulse was applied can be determined or measured in different ways.
  • a timer or an oscillator e.g., a quartz crystal or a piezoelectric oscillator, with a predetermined frequency can be used to determine the duration.
  • the timer or oscillator can be a device with a particularly high reliability. Errors in determining the time duration and/or in determining the speed are thus essentially ruled out.

  • Fig. 1b shows a speed-time diagram for the first embodiment of the method according to the invention.
  • the elevator car 10 of an elevator 5 is automatically braked by a brake 18 or a plurality of brakes and further movements of the elevator car 10 along the height of the elevator shaft 15 are blocked.
  • the brake 18 or brakes is de-energized in the locked or blocked state. If the elevator car 10 has not been braked to the height of a floor, the elevator car 10 must be moved to the height or level of a floor or other exit option so that the passengers can be evacuated from the elevator car 10 or can leave the elevator car 10 safely .
  • the brake 18 (or the brakes) of the elevator car 10 is repeatedly released by electrical impulses, so that the elevator car 10 can move incrementally or piecemeal along the height of the elevator shaft 15 during the respective release of the brake 18 .
  • the electrical impulses are usually triggered manually, i.e. by an operator or maintenance person.
  • the brake 18 While the electrical pulse is applied to the brake 18, the brake 18 remains open and the elevator car 10 can move by gravity. Alternatively or additionally, the elevator car 10 can be weighed down with weights and/or pulled with ropes along the direction of the elevator shaft 15 .
  • the electrical pulse can be applied or generated to the brake 18 by a controller or a microcontroller.
  • the controller can be a controller or microcontroller, which takes on additional tasks for controlling the movement of the elevator car 10 in the normal case. However, it is also conceivable that a special controller or microcontroller is present.
  • the pulse generating device 30 or the controller can be a device with a particularly high level of reliability, so that errors when applying the electrical pulse or when ending the electrical pulse are essentially ruled out.
  • individual components of the pulse generating device 30 or the controller or even an entire brake opening device 20 designed therewith can be designed as safe components which, for example, meet a safety requirement level (Safety Integrity Level - SIL) SIL-2, SIL-3 or even SIL-4 .
  • a safety requirement level Safety Integrity Level - SIL
  • the temporal lengths or durations or time spans of the electrical pulses can be of different sizes.

  • the electrical impulse can in particular be a square-wave impulse. This means that the electrical impulse is either at its maximum level or at its minimum level (e.g. zero level). Values in between only occur for a very short time, if at all.
  • the electrical pulse can be a square-wave voltage pulse.
  • the electrical impulse is the interruption of a current signal or voltage signal, which current signal or voltage signal is normally present at the brake 18 during the power failure.
  • the electrical impulse then interrupts the current signal or voltage signal which ensures that the brake 18 is closed, and in this way opens the brake 18.
  • the brake release device 20 has a pulse generating device 30 and a determination device 40 .
  • the pulse generating device 30 is designed to apply the electrical pulse to a brake 18 of the elevator car 10 to release the brake 18 , the brake 18 being released as long as the electrical pulse is present at the brake 18 .
  • the determination device 40 is designed to determine or detect a distance covered by the elevator car 10 during a vertical movement of the elevator car 10 while the respective electrical pulse is being applied to the brake 18 .
  • the speed of the elevator car 10 can also be determined or calculated by means of the determination device 40 . It is also possible for the determination device 40 to determine the length of time since the electrical pulse was applied.
  • the brake opening device 20 can function as a pulse electric brake opening device (PEBO).
  • the application of the electrical impulse to the brake 18 is terminated when the elevator car 10 has moved a predetermined distance d max along the elevator shaft 15 while the brake 18 is released by the application of the electrical impulse. After the application of the electrical pulse to the brake 18 is terminated, the brake 18 closes again and thus brakes the elevator car 10 so that the elevator car 10 can no longer move until the brake 18 is released again.
  • Fig. 1a the time t is plotted on the x-axis and the distance d covered by the elevator car 10 along the elevator shaft 15 is plotted on the y-axis.

  • variable pause in which no electrical pulse is applied to the brake 18 .
  • the variable pause may depend, for example, on how long the brake 18 was open during the immediately preceding electrical impulse. If the brake 18 was opened for a longer period of time, the pause before the next electrical pulse can be longer accordingly. Also, the variable pause may depend on the distance traveled during the immediately preceding electrical impulse. It is also conceivable that the variable break depends on the distance covered within a specified period of time (e.g. within the last minute).
  • the speed v of the elevator car 10 increases in Fig. 1b slightly faster than linear.

  • the application of the electrical impulse is ended when the elevator car 10 has covered the predetermined maximum distance d max during the opening of the brake 18 or when the electrical impulse is (at least) for the time period or time span t max on the brake 18 plant. If at least one of these two termination conditions is met, the application of the electrical pulse is terminated in the method or the brake opening device 20 .

  • the further termination condition is met if the specific period of time is equal to or greater than the specified period of time t max .
  • the maximum or predetermined time period or time span t max can be in the range of seconds, for example 10 s. This ensures that the elevator car 10 does not move longer than the time period or time span t max at a time, ie without interruption emotional. Consequently, it is ensured that the passengers in the elevator car 10 are not frightened. If the brake 18 is opened for any length of time or for a very long time, ie until the specified distance d max has necessarily been covered, under unfavorable circumstances the passengers could get the impression that the brake 18 is no longer working.
