Definitions

  • the invention relates to a safety device for an elevator installation with at least one elevator car according to the preamble of the independent claims.
  • the invention relates to a corresponding elevator installation.
  • elevator cars in a multi-vehicle elevator system are each equipped with their own drive and their own braking system.
  • the electronic control of the entire elevator system is often designed so that there should be no collisions of the individual elevator cars. Particularly in the case of an emergency stop or even in the case of a normal floor stop of a cabin, it can not be ensured under all circumstances that a further elevator car situated above or below the same elevator shaft can still stop in time to avoid a collision. This could be avoided by giving the controller sufficient distances between the individual elevator cars and also adapted vertical speeds. Such a requirement, however, can not fully utilize the transport capacity of a multi-vehicle elevator installation, which has an impact on the cost-benefit efficiency.
  • a multi-mobile elevator system which includes means for opening the safety circuit of an elevator car, if it comes to an undesired approach to another elevator car.
  • security modules are present at each elevator car, which evaluate the car positions and speeds in order to be able to trigger braking operations on other elevator cars, if necessary.
  • the individual safety modules must always know and evaluate the cabin positions and speeds of the other elevator cars involved in order to be able to react correctly in an emergency. To it needs a special decision module, which is responsible for determining the stop commands in an emergency.
  • a first object of the present invention to provide a multi-vehicle elevator system, which are automatically stopped at an approach between two elevator cars, the cabs before driving without a complex exchange of information between the elevator cars is necessary.
  • a further object of the present invention is to prevent an undesired approach or collision of the car with the shaft ends in an elevator installation with at least one elevator car when the elevator car approaches the shaft ends.
  • the present invention is equally suitable for preventing a collision between two elevator cars that are relatively approaching and one for preventing a collision between an elevator car and a shaft end.
  • equivalent variants of the safety device according to the invention for an elevator installation will be described.
  • the safety device for an elevator installation with an upper elevator car and a lower elevator car both of which can be moved substantially independently along a vertical direction in a common elevator shaft of the elevator installation, comprises a first electro-optical detection system with a first light source in a lower area the upper elevator car and with a first detector.
  • the first detector has a photosensitive, first sensor area in an upper area of the lower elevator car.
  • the first light source outputs a collimated first light beam at a first angle with respect to the vertical direction. The first angle is predetermined so that when approaching the upper and lower elevator cars, the first light beam strikes the first sensor area and is thus detectable by the first detector and the first detector triggers a reaction to prevent a collision of the elevator cars.
  • the safety device has a second electro-optical detection system with a second light source in an upper region of the lower elevator car and a second detector in a lower region of the upper elevator car comprises.
  • the first variant can also be implemented with more than two elevator cars, which can be moved substantially independently vertically in a common elevator shaft. Where then between each of these elevator cars at least one light source and provided for this detector is present.
  • the safety device for an elevator installation with a lower shaft end and with at least one elevator car which is movable substantially independently along a vertical direction in an elevator shaft of the elevator installation, comprises a first electro-optical detection system with a first light source in a lower area of the elevator system Elevator car and with a first detector.
  • the first detector has a photosensitive, first sensor area in the region of the lower shaft end.
  • the first light source outputs a collimated first light beam at a first angle with respect to the vertical direction. The first angle is predetermined such that when the elevator car approaches the lower shaft end, the first light beam strikes the first sensor area and is thus detectable by the first detector and the first detector triggers a reaction to prevent a collision of the elevator car.
  • the safety device has a second electro-optical detection system with a second light source in the region of the lower shaft end and via a second detector in a lower region of the elevator car.
  • the safety device for an elevator installation with an upper shaft end and with at least one elevator car which is movable substantially independently along a vertical direction in an elevator shaft of the elevator installation, comprises a first electro-optical detection system with a first light source in the region of the upper shaft end and with a first detector.
  • the first detector has a photosensitive, first sensor area in the upper area of the elevator car.
  • the first light source outputs a collimated first light beam at a first angle with respect to the vertical direction. The first angle is predetermined such that, when the elevator car approaches the upper shaft end, the first light beam strikes the first sensor area and is thus detectable by the first detector and the first detector triggers a reaction to prevent a collision of the elevator car.
  • the safety device has a second electro-optical detection system with a second light source in an upper region of the elevator car and a second detector in the region of the upper shaft end.
  • the elevator car of the second variant may be the lower of several elevator cars in a common elevator shaft of the elevator system of the first variant, both of which are substantially independently movable along a vertical direction in the elevator shaft.
  • the elevator car of the third variant can be the upper one of a plurality of elevator cars in a common elevator shaft of the elevator system of the first variant, both of which can be moved substantially independently along a vertical direction in the elevator shaft.
  • An advantage of the invention results from the simple arrangement of commercially available electro-optical components in order to prevent a collision of an elevator car in an elevator shaft. Another advantage is thesurgiigen detection of the distance by the detector and the triggering of an autonomous reaction to unwanted approach of the elevator cars. Furthermore, the detector in conjunction with a local computing unit is capable of triggering a collision-preventing reaction based on speed information with a small amount of computation. In addition, the redundant design of the safety device provides additional security and enables an autonomous and rapid collision-preventing reaction of all elevator cars.
  • a first embodiment of the invention is described in connection with the two snapshots in Figures 1A and 1B.
  • Shown is a simple multi-vehicle elevator installation 10 with an upper elevator car A1 and a lower elevator car A2, both of which can be moved substantially independently vertically in a common elevator shaft 11 of the elevator installation 10 along a vertical direction z.
  • the elevator cabs A1, A2 are provided with a drive and a holding brake per elevator car A1, A2, or, for example, can be individually coupled to a central drive system in order to allow individual movement in the elevator shaft 11.
  • a safety device which comprises a first electro-optical detection system 20 with a first light source 21, which is arranged in a lower area of the upper elevator car A1, as schematically indicated in FIGS. 1A and 1B.
  • Particularly suitable light sources are light-emitting diodes which emit concentrated light. Even better are laser diode or solid state laser.
  • the detection system 20 comprises a first detector 22, which comprises a photosensitive, first sensor area 22 in an upper area of the lower elevator car A2.
  • a first detector 22 which comprises a photosensitive, first sensor area 22 in an upper area of the lower elevator car A2.
  • sensor region 22 photodiodes, phototransistors or other photosensitive elements can be used.
  • the first light source 21 is designed and arranged to emit a collimated first light beam L1 at a first angle W1 with respect to the vertical direction z in.
  • the light beam L1 is directed downwards.
  • the light beam L1 strikes the sensor area 22 for the first time.
  • the first angle W1 is predetermined or adjusted such that, as the upper and lower elevator cars A1, A2 approach, the first light beam L1 strikes the first sensor region 22 as soon as the minimum distance S2 is reached. At this instant of impact, the light beam L1 is thus detectable by the first detector 22, 24, and this detector 22, 24 triggers a reaction R1, which is passed on to a controller or the like, for example via a line or connection 23.
  • the present invention now permits various forms of implementation or expansion stages of the safety device.
  • a reaction can be triggered immediately upon first contact of the light beam L1 with the sensor region 22.
  • the sensor region 22 has a size-in the sense of surface area-that makes it possible to ensure that reliable detection of the light beam L1 by the detector 22, 24 is possible despite the fluctuations in the elevator installation 10 ,
  • FIG. 1 Another embodiment of the invention is indicated in FIG. In this figure, a snapshot is shown shortly after the light beam L1 was first detected by a photosensitive portion 22.1 of the sensor portion 22.
  • the sections are preferably evaluable separately, i. They each have individual electrical connections.
  • a corresponding evaluation system 24 (or 24 and 28 in the case of FIG. 3) is preferably provided in order to be able to trigger an adapted reaction (R1, R2, R3, R4) depending on which of the sections 22.1-22 .n the first light beam L1 meets.
  • the safety device can now be configured, programmed or set such that upon the first impact on the section 22.1 of the sensor region 22 an advance warning is issued as a reaction or the elevator installation 10 or the elevator car A1 and / or A2 is transferred to a pre-warning mode. If the light point now exceeds a predetermined further section 22.4 of the sensor region 22, a final reaction can be triggered (for example an emergency stop by triggering the brake device or the safety brake of the upper and / or the lower elevator car A1, A2). This two-step approach adds security and helps prevent false tripping.
  • the light spot moves to the left at a speed v1 * when the relative distance between the elevator cars A1, A2 is reduced at a speed vI.
  • a further variant is shown. This variant is currently preferred because it offers the greatest security.
  • two electro-optical detection systems are used.
  • the first detection system is designed analogously to the system shown in the preceding figures.
  • the second Detection system can be identical, but sits almost mirrored in the upper part of the lower elevator car A2.
  • the corresponding second sensor area 26 is seated in the lower area of the upper elevator car A1.
  • the detectors trigger reactions in each case.
  • the nature of the reactions differs depending on the embodiment, programming or setting of the devices.
  • the detectors are capable of delivering signals or information via lines or other connections 23 or 27. These signals or information are then either processed before reactions are triggered, or they immediately trigger the responses, for example, by opening a switch that is part of a safety circuit.
  • the elevator installation 10 has its own safety circuit per elevator car A1, A2, the safety circuit of the upper and / or lower elevator car A1, A2 can be interrupted by the detector (s).
  • a multi-mobile elevator installation 10 preferably has one own safety circuit per elevator car A1, A2, in which several safety elements, such as safety contacts and switches, are arranged in a series connection.
  • the corresponding elevator car A1 or A2 can only be moved if the safety circuit and thus also all safety contacts integrated in it are closed.
  • the safety circuit is connected to the drive or the brake unit of the elevator installation 10 in order to interrupt the driving operation of the corresponding elevator car A1 or A2, if such a reaction is desired.
  • the invention can also be used in elevator systems which are equipped with a safety bus system instead of the mentioned safety circuit.
  • any catch brakes of the respective elevator cars A1, A2 can be triggered.
  • angles W1, W2 can be adjusted in a range of 0 to 90 ° with respect to the vertical direction z.
  • the angles W1, W2 are in the range between 0 and 60 degrees, and more preferably between 10 and 50 degrees.
  • the angle W1, W2 as a function of individual or several parameters, such as the position, speed or acceleration of an elevator car A1, A2, the distance, relative speed or relative acceleration of the elevator car A1, A2 to a reference point or the operating state of the elevator system 10, in time set variably.
  • the angle W1, W2 can be set smaller, so that the light beam L1, L2 falls on the detector 22, 24 at an earlier time and thus to it an earlier time a reaction R1, R2, R3, R4 can trigger.
  • the need for an early response R1, R2, R3, R4 is reduced, and thus a larger angle W1, W2 can be set.
  • the relationship between acceleration and angle is analogous.
  • the angle W1, W2 of the light beam L1, L2 can be increased already after the transfer of the elevator car A1, A2 into an inspection state, since the elevator car A1, A2 can only be moved at reduced speed.
  • the position of the elevator cars A1, A2 serves, for example, to determine the time of a variable adjustment of the angle W1, W2. Accordingly, a critical distance between the elevator cars A1, A2 or between an elevator car A1, A2 and the shaft end defined. If this value is undershot, the variable setting of the angle W1, W2 begins.
  • corresponding sensor areas can also be provided at the lower and / or upper shaft end of the elevator shaft 11 in order to prevent a dangerous approach of an elevator car to the respective shaft end.
  • the operating principle in this case is the same as described in connection with the other embodiments.
