Definitions

  • the invention relates to an unlocking device by means of which a safety cover for opening a maintenance opening can be released.
  • the invention relates to an elevator installation with this unlocking device and a method for actuating the unlocking device.
  • An elevator system has several components, such as a drive, guide rails, cabin guide shoes, braking systems or the like, which must be maintained at regular intervals in order to ensure trouble-free and safe operation.
  • a large number of these components are arranged in a shaft of the elevator installation.
  • a maintenance technician For the maintenance work, a maintenance technician must have appropriate access to the inside of the shaft. This is usually done via a maintenance opening, which is covered by a safety cover, such as a shaft door or a panel. Since an elevator car is moved inside the shaft, special security measures are required when entering the inside of the shaft.
  • a locking of a shaft door of an elevator system is described.
  • the lock is deactivated when two serially arranged switches are closed.
  • the first switch can be closed by a technician using a button.
  • the second switch is closed when an elevator car is in a fixed position. Further conditions do not have to be fulfilled for the locking to be deactivated.
  • the shaft access system comprises a control unit that controls access to the shaft, in particular via a shaft door.
  • the shaft access system can be operated in different modes, in particular in a normal operating mode and in a maintenance mode. The mode can only be changed by an authorized person, such as a maintenance technician, by entering a code on the control unit. When changing the operating mode, one or more landing doors are released for opening.
  • a disadvantage of this solution is that the mode can be changed due to a software error in the control unit or due to unauthorized manipulation of the control unit. In the event of such an unintentional change of mode, the shaft door is nevertheless released for opening. Accordingly, unauthorized people can enter the shaft.
  • the shaft door released for opening cannot always be arranged in the immediate vicinity of the control unit. For example, if access to the shaft pit is to be released via the lowest shaft door and the control unit is located in the area of the elevator control on the top floor of the building, the lowest shaft door released for opening is unattended for the duration of the walk between the control unit and this lowest floor door. For this period of time, an unauthorized person could gain access to the shaft through this floor door.
  • an unlocking device with an actuator, by means of which a safety cover of a maintenance opening can be released for opening.
  • the unlocking device has a safety circuit via which the actuator can be activated.
  • the safety circuit comprises at least a first switch contact and a second switch contact, the actuator when the switch is closed State of the first and the second switching contact can be connected to an energy source via the safety circuit.
  • the first switch contact and the second switch contact are arranged in series in the safety circuit.
  • Another aspect of the invention relates to an elevator device with said unlocking device and a method for operating the unlocking device.
  • the first switch contact can be switched by means of a control unit. According to the invention, the control unit is provided to make an authorization request before the switching contact is switched.
  • control unit can query or check other conditions that must be met for the release to open the safety cover. For example, it can be checked whether the elevator car is in a predetermined position or a predetermined area within the elevator shaft, whether shaft lighting is switched on, whether the elevator car is stationary and / or whether people or material are in the elevator cabin.
  • a safety cover is designed to prevent unauthorized persons from accessing the shaft.
  • a safety cover can be designed differently and includes both doors that cover, for example, a shaft door opening or a cabin door opening, or simple panels that cover a maintenance window or a hatch.
  • every second switching contact is arranged in series with the first switching contact.
  • the plurality of second switch contacts can be arranged in parallel and / or in series with one another.
  • a control unit is understood here to mean a unit which has at least one microprocessor, one working memory and one permanent memory. Such a control unit is thus designed to execute computer-aided programs and to control or switch the first switching contact.
  • the control unit can, for example, be designed as an elevator control which, in addition to the basic tasks intended for an elevator control, such as the registration of car calls or the assignment and execution of trips of the elevator car, also switches the first switching contact.
  • the control unit can also be configured as a safety control unit, which monitors the safety-relevant states of the elevator installation and, when an unsafe state occurs, brings the elevator installation back into a safe state.
  • control unit can also only be provided to switch the first switching contact.
  • control unit is dedicated to the safety circuit.
  • the first switching contact can preferably be switched as a function of an operating mode of an elevator installation.
  • the first switch contact is when changing Switchable from a normal operating mode to a maintenance mode of the elevator installation by means of the control unit in a closed state.
  • the second switching contact can preferably be switched by manual manipulation.
  • Manual manipulation is understood to mean manual actuation on an actuation device, such as an actuation button, which is operatively connected to the second switch contact and via which the second switch contact can be switched.
  • the switching contact can take place due to a pressure or pressing movement of one hand of the maintenance technician.
  • the actuation device can also be implemented as an electromechanical actuation mechanism that is actuated manually via a button, touch-sensitive screen or the like.
  • the second switch contact is preferably arranged in an actuation area for opening the safety cover.
  • the second switching contact is arranged in such a way that the maintenance technician is already in one when switching the second switching contact Actuation area for opening the safety cover is located. This ensures that the safety cover is only opened in the presence of the maintenance technician and thus the probability of incorrect manipulation by an unauthorized person is reduced.
  • An actuation area is understood to mean an area in spatial proximity to the safety cover, in particular an area that is sufficiently close to the safety cover that a maintenance technician who is in this area can open or at least see the safety cover after the release to open the safety cover .
  • the second switching contact can optionally comprise a first two switching contact and a second second switching contact. Both second switch contacts can be switched by manual manipulation. It is particularly advantageous that in this optional embodiment of the second switching contact, both second switching contacts are arranged in the actuation area. In particular, both second switch contacts can be arranged such that when the safety cover is released, both hands of the maintenance technician are in a predefined position. In addition, the safety circuit can be configured in such a way that the safety cover is only released if both second switch contacts are switched manually at the same time. This ensures that both hands of the maintenance technician are actually in the predefined positions.
  • the actuator is preferably designed as a permanent electromagnet.
  • the permanent electromagnet is arranged with respect to the safety cover in such a way that it holds the safety cover in a position covering the maintenance opening in an inactive state and releases the safety cover for an opening in an active state.
  • the permanent electromagnet is fixedly mounted on the elevator car and exerts a magnetic attraction force on the safety cover which is opposite to a movement to open the safety cover.
  • the magnetic attraction is to be dimensioned such that the Safety cover from the permanent electromagnet holds reliably in the position covering the maintenance opening.
  • the actuator is designed as an electromagnetic pawl.
  • the electromagnetic pawl comprises a lever arm, preferably with a hook, which is designed to engage in a holding device and a controllable electromagnet for actuating the lever arm.
  • the holding device can for example be designed as a protruding bracket, stop, recess or the like.
  • the electromagnetic pawl is arranged with respect to the safety cover in such a way that, in an inactive state in which the electromagnet is separated from the energy source, it holds the safety cover in a position covering the maintenance opening and in an active state in which the electromagnet with the energy source connected, the safety cover for an opening.
  • the electromagnetic pawl is, for example, permanently mounted on the elevator car and engages in the holding device arranged on the safety cover by means of the lever arm.
  • the engagement of the pawl in the holding device creates a mechanical operative connection which counteracts a movement to open the safety cover.
  • the elevator installation comprises an unlocking device described above, a safety cover for covering a maintenance opening, an energy source for activating an actuator of the unlocking device, a control unit for switching a first switching contact of the unlocking device and a manually actuable actuating device for switching a second switching contact of the unlocking device.
  • the maintenance opening is preferably designed as a cabin roof hatch, cabin floor hatch, cabin maintenance window, cabin access opening or shaft access opening.
  • the safety cover is designed accordingly as a door, panel or the like.
  • the first switching contact is preferably closed by the control unit. Furthermore, the first switching contact is closed as a function of an operating mode of an elevator installation by the control unit, in particular when changing from a normal operating mode to a maintenance mode. Finally, the second switch contact is closed by manual manipulation
