Definitions

  • An elevator installation normally comprises an elevator car, an elevator shaft in which the elevator car moves, and a drive unit for moving the elevator car.
  • an elevator system is designed so that at the bottom of the shaft a shelter in the form of a pit is to ensure that maintenance personnel in the shaft is not endangered when the elevator car moves to the lowest position in the shaft.
  • an elevator system is also designed to have a shelter at the top of the shaft, called the shaft head, so that maintenance personnel performing maintenance on the roof of the car is not endangered when the car is in the uppermost position in the bay.
  • the shelter at the lower end of the shaft now typically has a height of 50 cm plus the length of the maximum compressed buffers located at the bottom of the shaft located to cushion the counterweights or the elevator car.
  • An elevator system with a shelter at the lower and upper shaft ends is several meters longer than the actual floor height of the building, which is served by the elevator. This often leads to solutions in which the elevator shaft towers over the building.
  • a part of the drive unit was mounted in a machine room above the shaft, that is, one has either dimensioned the elevator system so that the top floor was not operated, since here was the engine room and shelter, or you have the engine room including shelter on the roof of the building realized.
  • European Patent Application EP 1052212-A describes a device which allows work to be carried out in a hoistway. According to this patent application, a shelter is realized at the upper end of the shaft by prematurely stopping the counterweight at the lower end of the shaft. As a result, the car - which is connected to the counterweight via a cable system - can not be driven to the shaft head.
  • US Pat. No. 6,223,861 describes a safety system for an elevator in which the elevator is moved only at reduced speed if a person is in the elevator shaft. Whether a person is in the elevator shaft is determined by sensors on the shaft doors. If the elevator moves at a reduced speed, special switches at the lower and upper shaft ends stop the car, preventing the car from entering the shelter.
  • EP 1 110 900 discloses a security system having the features of the preamble of claim 1.
  • the elevator installation according to the invention and the corresponding method offer various advantages, such as, for example, better use of the building or space. Elevator systems according to the invention are also better suited for particularly representative buildings and facilities, as they can be better integrated architecturally into an overall concept because of the shorter construction of the shaft. This is particularly important for freestanding elevator systems.
  • the elevator system according to the present invention is characterized by lower dead times, since the operation, albeit to a limited extent, is maintained during maintenance.
  • the present invention is essentially independent of the type of elevator disposition or the type of drive used. For this reason, the ropes or rails, counterweights and other elements are considered below as part of the drive unit and only as far as necessary individually described or resolved.
  • the control is also considered as part of the drive unit.
  • a conventional elevator installation 10 is shown in FIG.
  • the system 10 shown comprises a shaft 11 with a cabin 12, which can approach different floor levels 13.1 to 13.n.
  • the drive unit comprises the cable 14.1, the rollers or suspensions 14.2 to 14.6, the drive motor (not shown) and the control unit for controlling the drive motor (not shown).
  • a well pit 15 At the lower end of the shaft is a well pit 15, which serves as a lower shelter.
  • a shelter 16 is provided in order not to endanger a person 17 who is on the roof of the car 12.
  • FIG. 20 A system 20 according to the invention is shown in FIG.
  • the system 20 has an elevator car 21, which is movable in an elevator shaft 22, as indicated by the double arrow 23.

  • the cabin 21 is driven by a drive unit 25.
  • the drive unit 25 comprises a control unit 26 and a motor 27.
  • the control unit receives input signals via an input 28, for example from an operator keyboard (not shown) in the cab 21.
  • the speed curve can be specified, for example, in the form of setpoints, which are compared with the current actual values. If there are deviations between the actual and set values, a control loop is used to make corrections.
  • the control unit 26 controls the cabin 21 so that it can - depending on the requirements - stop in the different floors.
  • the elevator installation 20 comprises a detection device 29 which detects whether a person is in a critical zone of the elevator.
  • Critical zones are either the end zone 32 at the lower end of the shaft and / or the end zone 33 at the upper end of the shaft (shaft head).
  • the detection of the presence of a person on the cabin roof or its access to the cabin roof is preferably used.
  • the detection device 29 is connected to the drive unit 25 in such a way, for example via a line or a bus 31, that the elevator installation 20 can be converted into a special operating mode if a person is in the critical zone or is about to enter it ,
  • the drive unit 25 comprises a special control device 30, which may be integrated in the control unit 26 and in the special Operating mode, the elevator car stops, at the latest before it enters the critical zone 32 and / or 33.
  • the detection device 29 and the special control device 30 are safety-relevant designed to prevent in all circumstances the retraction of the elevator car 21 in the critical zone 32 and / or 33.
  • the special control device 30 allows undisturbed operation of the elevator car 21 in a zone outside the critical zone 32 and / or 33.
  • the elevator car 21 can continue to operate the storey levels 24.2 and 24.3, for example in the special operating mode.
  • safety-relevant is to be understood in the present context as meaning that it is an elevator system that is reliable and in particular reliable in that, for example, the essential components are redundant, important functions of the control device (30, 42) run in parallel and their Results are compared with each other and the data is transmitted over parallel lines or known methods for transmission error detection are applied.
  • a virtual protection zone at the shaft bottom and / or at the shaft head is created at the latest when entering a critical zone 32 and / or 33.
  • the virtual protection zone must be absolutely secure, in order to prevent the danger of persons or even personal injury. Only if this is guaranteed, you can do without a pit or an upper shelter.

  • the detection device 29 supplies one or more signals or information to the special control device 30.
  • the special control device 30 is linked to the control unit 26 or integrated into the same, so that an immediate switchover to the special operating mode takes place automatically.
  • the elements of the detection device can be arranged at different locations inside or outside of the shaft 22 and / or on the cabin 21.
  • detection device 29 It is advisable to carry out the detection device 29 separately and independently of the usual sensors and control means of the elevator installation 20 in order to ensure increased safety.
  • the connection between the detection device 29 and the special control device 30 should be carried out autonomously by other systems, or special safety measures should be taken.
  • a safety bus as known from US Pat. No. 6,173,814 may be used.
  • FIG. Here are the Sensors 40.1, 40.2 and 40.3 of a detection device 43 connected to the nodes of a safety bus 41.

  • the special controller 42 may be programmable to allow for certain adjustments and subsequent updates. Rules can be specified which lead to switching to the special operating mode. The emphasis is on the greatest possible security, as shown by the following example.
  • FIG. 5 shows by means of an exemplary curve 51 how a conventional elevator can be controlled.
  • the curve 51 shows the speed as a function of the path x traveled by the elevator.
  • the path length corresponds to the distance between the lowest and the highest floor level served by the elevator. Both when starting, and when braking the elevator car, the drive is controlled so that low acceleration forces occur.
  • the curve 51 is a speed setpoint curve for driving over the maximum travel path of the elevator car, for example for a drive from the floor above the shaft pit to the floor below the shaft head.
  • a speed setpoint curve can also be generated only over a floor distance or a few floor distances.
  • an elevator installation is equipped with encoders which continuously measure actual values of cabin position and cabin speed and forward it to the control unit (eg the control unit 26 in FIG. 2). The actual speed values are then compared with the speed setpoints. From this, the control unit determines whether further acceleration is required, whether the elevator can continue to run at the current speed, or whether it must be braked.
  • the elevator system automatically switches to a special operating mode as soon as someone is in the shaft or intends to enter the shaft.
  • a system according to the invention is characterized in that the special operating mode makes it possible to autonomously influence certain control variables.
  • the special control device 30 is connected downstream of the actual control unit 26 of an elevator installation, in such a way that the special operating mode always has priority over the normal operating mode.
  • the mode of operation of an advantageous embodiment is shown in FIG.
  • the speed setpoint curve 51 for the maximum possible travel path of the elevator is shown in the uppermost box.
  • a curve is usually a velocity setpoint curve.

  • the travel path area to which the maximum speed setpoint curve refers is reduced by the shaft areas to be protected. If no changeover to the special operating mode takes place, the speed setpoint curve 51 continues to be used.
  • the speed setpoint curve 51 is adapted to the operating mode. If the elevator installation is in the normal operating mode, the speed setpoint curve 51 is used. In contrast, in the special operating mode, the distance which the elevator car can travel maximum is shortened. This is shown schematically by the curve 52 in FIG. In the example shown, the characteristic curve of the velocity curve continues to be used. This means that the elevator car is accelerated and decelerated as in normal operation. The normal speed v n also remains unchanged in the example shown. By shortening the distance two virtual protection zones 53 and 54 are created at the shaft foot and the shaft head. In the example shown, the height of the two virtual protection zones 53 and 54 is 2 m each.
  • Such an embodiment, which provides only one virtual protection zone 62 at a time, may be used if the detection device is designed to be able to distinguish whether a person is in the lower or upper shaft area stops, or is about to gelarigen in the lower or upper shaft area.

  • a special control device can be used which automatically assumes control of the drive control during the entire duration of the special operating mode. In this case, it is not assumed that the speed setpoint curve active in the normal operating mode, but the special control device provides an appropriate curve. Such a curve can be taken from a memory or generated from a table with parameters or with setpoints. If the elevator system is in the special operating mode, then In the presently described embodiment, the special controller takes control of the drive control. Also in this embodiment, a control mechanism is typically used which measures the actual values on the elevator installation and compares them with the desired values in order to determine control variables for the drive control.
