Definitions

  • the present invention relates to a safety switching system for an elevator installation and a method for switching an elevator installation between a normal operating mode and an inspection operating mode. Furthermore, the invention relates to an elevator system with such a safety switching system.
  • An elevator system is used to transport people within buildings, with an elevator car being able to move between different floors in an elevator shaft.
  • safety-relevant current states of a number of its components should be monitored within an elevator system.
  • the elevator system is put into an inspection or maintenance mode in which either operation of the elevator car is blocked or the elevator car may only move under manual control at walking speed or only between certain floors can be moved.
  • a service technician In order to be able to carry out an inspection and maintenance work in an elevator shaft, a service technician must enter an elevator shaft via a shaft door, with a maintenance switch normally having to be actuated before entering the elevator shaft, which switch is usually located inside the elevator shaft next to the shaft door .
  • the maintenance switch can, for example, be referred to as an emergency stop switch which, when activated, can interrupt what is known as a safety chain—also known as a safety circuit.
  • the safety chain is a serially connected circuit with a discrete number of switches designed to indicate the status of the doors and the position of the elevator car.
  • a door switch is present on a car door of an elevator car and on each shaft door, which is closed as long as the respective door is closed.
  • the safety chain is a series circuit that has switches and contacts.
  • the safety chain operates relays that control power to the electric motor and brake. Some parts of the safety chain can be bypassed, other parts can be inserted to change the safety monitoring for special operations during inspection, maintenance and rescue operations.
  • the inspection or maintenance mode can be ended by actuating, e.g. deactivating the control device and the maintenance switch, and by closing or locking the shaft door and, as a result, by closing the safety chain, the elevator system can start regular driving operation be offset, in which the elevator control can move the elevator car. In regular driving operation, the elevator car can be moved, for example, despite the presence of personnel in the elevator shaft.
  • the EP 2033927 A1 relates to a safety device of an elevator system. If an elevator car with an open car door leaves a door zone or reaches a door zone with an impermissible acceleration or speed, a control signal for braking the elevator car is generated.
  • the EP 1159218 A1 describes an elevator safety system in which an electronic safety control device can communicate with a plurality of bus nodes via a safety bus.
  • the electronic safety controller processes the data received from the bus nodes and determines whether an unsafe condition exists and if so, the safety controller sends a stop signal to the drive and brake unit and also sends a status signal to the elevator controller.
  • the EP 2214998 A1 discloses a system for detecting the presence of a person within an elevator shaft.
  • the system includes a passive infrared detector positioned to detect infrared radiation from within the elevator shaft and a local processor that compares an infrared profile generated by signals from the passive infrared detector with a reference infrared profile to determine if a person is present in the elevator shaft.
  • DE 110201101050918 T5 relates to an elevator safety controller which controls elevator operation from a safety standpoint.
  • Two reset switches 11 and 12 are disclosed, which an elevator system can set from a maintenance operating mode to an automatic operating mode.
  • the elevator safety controller can use the reset switches to determine the presence of a service technician. Before a safety chain is then immediately connected to an electric motor, it must first be checked whether a already closed safety chain of the elevator system has really been completely closed. Such reset switches can be placed inside or outside the shaft of the elevator installation.
  • the object of the invention is to ensure the occupational safety of an elevator system not only during maintenance/inspection or installation work, but also afterwards when the elevator system is switched back to a normal operating mode.
  • a safety measure with which it can be ensured that service personnel can safely enter an elevator shaft and, in particular, also safely leave it.
  • a safety switching system of an elevator system which comprises an elevator car and an electric motor, wherein the electric motor can drive the elevator car to move in a shaft of the elevator system, and the shaft comprises at least one shaft door.
  • the shaft door can be opened both alone and together with a car door of the elevator car.
  • the safety switching system has a safety chain, which includes at least one door contact switch for determining or monitoring an open and/or closed state of the shaft door or the car door and an operating device in the shaft in a series connection.
  • the operating device has a changeover switch for changing over the elevator installation to a normal or inspection operating mode.
  • the safety chain is closed to drive the elevator car via the electric motor, whereby a current path can be established between an electrical supply source and the electric motor.
  • the safety chain is broken to break the current path and thereby hold the elevator car.
  • the safety switching system also has a manual switch outside the elevator shaft and at least one control element.
  • the series connection of the safety chain can be electrically closed or interrupted by activating or deactivating the control element, while the current path to the electric motor remains permanently interrupted until the hand switch is actuated if the changeover switch of the Operating device switches the elevator system from the inspection operating mode to the normal operating mode.
  • the or at least one of the control elements can be activated by actuating the manual switch.
  • the or at least one of the control elements can be deactivated by switching the elevator installation to the inspection operating mode using the changeover switch. Since the safety chain can be controlled from outside the elevator shaft with the help of a control element, it is possible for the elevator system to first be switched to a normal operating mode and then, when exit from the shaft by service personnel is confirmed, to be set to normal operation.
  • the safety chain When switching the elevator installation from the inspection mode to the normal mode by means of the switch of the control panel, the safety chain is closed, but first it remains disconnected to the electric motor. In other words, in this case the elevator installation is in the normal operating mode, but it is not yet directly set to normal operation. A distinction must be made here that a normal operating mode is not the same as normal operation. Switching the elevator installation to a normal operating mode means that the elevator installation is now suitable for normal operation but has not yet been put into normal operation.
  • the safety chain is only connected to the electric motor for driving the elevator car after the manual switch outside the shaft has been manually confirmed at least once. If one views the drive or the electric motor as part of the safety chain, it should be understood that the safety chain as a whole remains permanently interrupted until a service technician has operated the hand switch manually.
  • the elevator system switched to normal operation. It can thus be ensured that the technician remaining in the shaft is protected before he has exited the shaft.
  • the safety switching system can be of much help to the technician, especially when there is maintenance/inspection work to be performed in the pit or he wants to have the elevator car move when he is in the pit. Because of this, the elevator installation can be reliably switched to an inspection mode and a normal mode without a dangerous Movement of the elevator car is possible when personnel are present in the shaft or under certain circumstances with a potential risk.
  • the control element is a control relay that has a control unit and one or more switches.
  • a relay could be a current relay, for example, and is able to switch over all switches of this relay simultaneously when current flows through its control unit.
  • the control relay can control an operating switch connected in series with the safety chain in order to establish or interrupt the current path to the electric motor.
  • One or more switches from the control relay(s) may serve as the operating switch.
  • the electric motor By opening or closing the operation switch, the electric motor can be disabled or enabled for driving. If all switches of the safety chain are closed physically or electrically, nevertheless the safety chain is disconnected from the electric motor by the operating switch. Even if a software error or faulty signal communication occurs and consequently a function of an elevator control fails, the safety chain can be switched reliably as a series circuit as a whole.
  • control element has one or more electronic circuits for controlling the safety chain and/or the current path. That is, instead of the control relay or relays, a different type of electronic circuit can be used, such as a programmable electronic system in safety-related applications (PESSRAL), which has the same function as the control relay or relays.
  • PESSRAL programmable electronic system in safety-related applications
  • the operating device has a control switch.
  • the operator device can control the electric motor via the control switch only in the inspection operation mode to drive the elevator car.
  • a control switch can be a direction switch, for example, via which the elevator car can be controlled to move in an upward or downward direction.
  • the electric motor therefore drives the elevator car to move in the normal operating mode, for example under an elevator control, automatically and in the inspection operating mode under a manual operation using the operating device.
  • the safety chain has at least one further switch, which is provided for switching the safety chain, for deactivating the operating device, for preventing and/or interrupting a movement of the elevator car.
  • the further switch can be an emergency stop switch, which is fastened, for example, to an inner wall of the elevator shaft or in the vicinity of a shaft door and/or is arranged on the operating device. By pressing the emergency stop switch, immediate remedial action can be taken if the operator panel fails and there could be a hazard.
  • a method according to the invention for switching an elevator installation between normal and inspection operation which comprises an elevator car and an electric motor, the electric motor being able to drive the elevator car in a shaft of the elevator system for movement, and the shaft at least includes a landing door.
  • a safety chain is designed as a series connection of at least one door contact switch and an operating device that is in the shaft, with an open and/or closed state of the shaft door being determined by the door contact switch.
  • the elevator installation is switched to a normal operating mode or to an inspection operating mode by a changeover switch on the operating device.
  • a current path is established between an electrical supply source and the electric motor through the closed safety chain for driving the elevator car and interrupted by the broken safety chain for holding the elevator car.
  • the safety chain and/or the current path can be controlled by a hand switch, which is arranged outside the shaft (5), and at least one control element (K1, K2, K3) in such a way that the series connection of the safety chain (14) is switched off by activating or deactivating the Control element (K1, K2, K3) is electrically closed or interrupted, while the current path remains interrupted by the electric motor until the manual switch is actuated, when the switch of the operating device switches the elevator system from the inspection operating mode to the normal operating mode.

  • An electric motor 12 drives an elevator car 8 in an elevator shaft 5 between different floors for transporting people.
  • a shaft door 11 is provided at each floor, and a car door (not shown) is provided at the elevator car 8 .
  • the shaft door 11 can be used alone or with the Cabin door can be opened or closed together.
  • At least one door contact switch 15 is provided on each of the shaft doors 11 and on the car door, with the aid of which it can be monitored whether the respective shaft or car door is currently closed or open.
  • the door contact switches 15 are connected in series, so that a part of the safety chain formed thereby is only closed as a whole when all door contact switches 15 are closed.

  • the safety chain 14 and the control circuit are fed separately from the current sources 10a and 10b.
  • the changeover switch 4 of the operating device 3 is in a normal operating switching position. Since a current flows through the control unit S1, the switches K1-1 and K1-2 are closed, as a result of which the safety chain 14 is closed.
  • the elevator installation 1 can now be driven by the electric motor 12 .
  • the safety chain 14 can be manually closed or interrupted by means of the operating device 3 during an inspection work. It is assumed that the operating device 3 is located in the pit 5a of the shaft 5 and the inspection work is to be performed in a pit 5a. After a technician (not shown) entered the chess pit 5a, he has the Switch 4 of the control unit 3 to switch to an inspection switching position.
  • the control relay K1 is activated when switching over, because a current flow from the current source 10b to the control unit S1 is interrupted.
  • the switches K1-1 and K1-3 are opened as a result of the activation of the control relay K1, whereas the switch K1-2 is closed. Thus, the safety chain 14 is broken first.
  • the safety chain 14 can be closed and interrupted again manually by the technician manually closing or opening the control switch or the direction switch 16 of the operating device 3 .
  • the elevator installation 1 or the elevator car 8 can thus be driven upwards or downwards in a controlled manner by the electric motor 12 .
  • the safety chain 14 remains interrupted for the time being when the technician switches the changeover switch 4 back to the normal operating switch position after the inspection work. At this moment he is still in the shaft 5.
  • the elevator system 1 has now been switched to normal operation, it cannot be set to normal operation in advance for safety reasons, because the safety chain 14 has been opened by the switches K1-1, K3-3 and the non-actuated control switch 16 always remains interrupted and the elevator car 1 can therefore not move automatically in the meantime.
  • the technician can then leave the shaft pit 5a and go to the outside of the shaft 5 via a shaft door 11 . In this case, the technician is safely protected on a stretch between the shaft pit 5 and the shaft door 11 .
  • 3.4 to 3.5 show how the safety switching system 2 switches when the technician exits the shaft 5 and has operated the manual switch 7 manually. Since the control unit S3 of the control relay K3 is fed by the current source 10b as a result of the manual switch 7 being switched on, the switches K3-1 and K3-5 are opened. At the same time, however, the switches K3-2, K3-3 and K3-4 are closed, as a result of which the safety chain 14 is connected to the second current source 10b through the switch K3-2. As a result of the closed switches K3-3 and K3-4, it in turn forms a continuous current path via the safety chain 14 to the control unit S2 of the control relay K2 ( 3.5 ). The activated control relay K2 then opens the switch K2-2. Since the switches K3-5 and K2-2 are opened, the electric motor 12 remains blocked in advance despite a closed safety chain 14.
  • the safety switching system 2 can then switch and set the elevator installation 1 back to normal operation. Now the technician releases the manual switch 7 or the manual switch 7 with a reset function releases itself. Then no more current flows through the control unit S3 and it is thus deactivated, whereby the switches K3-1, K3-5 are closed and K3-2, K3 -3 and K3-4 are opened.
  • the safety chain 14 is supplied again by the current source 10a via the closed switch K3-1.
  • the switching status of the safety chain 14 or of the safety switching system 2 corresponds to the switching status shown 3.1 match. That is, the safety switching system 2 has a closed safety chain 14, and the elevator system 1 is only reset to normal operation from this moment.
  • an elevator system 1 that has a safety switching system 2 according to the invention or is controlled by this system is ensured when switching from inspection mode to normal mode, because the elevator car 8 is prevented from moving unless it is determined whether a technician escaped from the shaft 5 of the elevator system 1 after inspection work. This is independent of whether the safety chain 14 is closed or interrupted. It can also be understood that, before a manual operation is carried out, the drive of the elevator car 8, for example the electric motor 12, is always disconnected from an electrical supply source 10a, 10b.
