Definitions

  • This invention relates to a lift which either has no pit at all, or only one lift pit pit with minimum pit depth.
  • the lift shaft is always at least a certain minimum longer than the effective travel path of the elevator car, and more specifically, longer than the effective maximum distance between the elevator car roof in the uppermost position of the elevator car down to the bottom of the elevator car in its lowermost position.
  • a special problem is the area below the lift cabin in the lowest level of access. Because it can happen traditionally that someone is in the pit, ie on the floor of the elevator shaft, either for maintenance or cleaning purposes, strictly prescribed temporary or permanent safeguards must be in place to reliably prevent that person from accidentally descending the elevator car can be injured or crushed.
  • the object of the present invention is therefore to provide a lift without lift shaft pit or with minimum lift pit depth, which nevertheless is able to meet the requirements of the elevator regulation with respect to the free space against the danger of crushing.
  • a lift with a lift cabin, which can be moved in a lift shaft on several levels of access, and with several shaft doors, which are arranged on the respective development levels and lock access to the elevator shaft.
  • the lift is characterized in that at least the shaft door of the lowest level of access has no emergency release or is permanently locked.
  • Emergency release is understood here to be an unlocking device that can be actuated by service personnel for inspection or maintenance purposes outside the elevator shaft in order to unlock a shaft door and thus release access to the elevator shaft.
  • the emergency release is designed so that service personnel can unlock the emergency release by means of a triangular key that can be inserted in the area of an openable shaft door in a Moscowöff.
  • the invention is not bound to this specific embodiment of an emergency release. It is open to the person skilled in the art to realize further known alternative embodiments of an emergency release.
  • a shaft door which has no emergency release. Accordingly, a permanently locked shaft door outside the lift shaft for inspection or maintenance purposes can not be unlocked.
  • a shaft door which is located on an approached by an elevator car access level, temporarily unlocked to release the access for passengers in or out of the elevator car.
  • the permanently locked shaft door from the interior of the elevator shaft or from the Liftkabineninnem be unlocked.
  • a permanently locked shaft door can also be unlocked via a control of the lift with appropriate equipment of the shaft door with an electromechanically actuated unlocking device.
  • the controller is preferably set by service personnel in an evacuation mode, in which the temporary unlocking a permanently locked shaft door is unlocked first.
  • a permanently locked shaft door In normal operation, therefore, a permanently locked shaft door always remains locked except for the above-mentioned exception of an opposite elevator car and can not be unlocked for inspection or maintenance purposes from outside the elevator shaft.
  • Under access to the lift shaft is understood in the context of the invention, a walk-in access to the elevator shaft on the shaft floor or on the car roof, the access to the shaft bottom is made impossible by technical measures. For example, a collapse in the elevator shaft below a lift cabin on the shaft floor from a development level above the lowest level of access is therefore not understood as access to the elevator shaft.
  • An advantage of the permanently lockable shaft door on the lowest level of access is that access to the shaft pit is denied and thus access to the area below the elevator car is impossible. As a result, no shelter is provided below the elevator car and a minimum lift pit pit depth is feasible. In a particularly advantageous design of the lift shaft, the pit can even be omitted.
  • the permanent shelter F consists of the entire interior of the elevator car itself or is formed above the elevator cabin.
  • one or more shaft doors have an emergency release above the shaft doors of the lowest access level.
  • only the shaft door of the uppermost access level has an emergency release or all shaft doors are underneath Access levels permanently locked. This ensures that access to the shaft can only take place above the elevator car or in the elevator cabin.
  • the required clearance or shelter for the service personnel is formed by the elevator car itself, if they are in the elevator car, or is formed above the same by the lift shaft head has a sufficient height, so that the required shelter is available when reaching the top level of access.
  • a shelter formed by the elevator car itself can only be mentioned if all maintenance from the interior of the elevator car out feasible and therefore a stay in the elevator shaft, whether above or below the elevator car, is never necessary and therefore this access is impossible from the outset with technical measures.
  • Figure 1 A lift with four levels of access, with minimum lift pit depth, with the elevator car in the top level of access;
  • FIG. 1 This lift with four levels of access, with the elevator cabin
  • FIG. 3 This lift with four levels of access, with the elevator cabin in the lowest
  • Urbanization level. 1 shows a cross section through a building with four floors 1 to 4, which are all developed by the elevator car 6 of the lift. Based on this drawing, the underlying this invention underlying principle is explained. But it is clear that such a lift can be run over less or even more floors. Also, the drive can be solved differently than shown here and includes all known drive variants with a. The embodiment shown here is therefore only an example embodiment and should not be understood in any way limiting the scope.
  • the elevator shaft 5 belonging to this lift is here practically the same height as the distance between the floor 7 of the lowest level of access 1 and the ceiling 19 of the floor of the uppermost access level 4.
  • the elevator car 6 is here in its uppermost position, that is to say on the uppermost level Development level 4.
  • the shelter F of this lift is always and permanently formed by the elevator car 6 itself, as will be explained.
  • the drive of this lift takes place in the example shown by a drive unit in the form of a gearless external rotor, which is mounted in a frame 9 on the shaft wall and is supported on rails, not shown.
  • the outer rotor forms a driving tube 16 and over this run the support means 10, on the one hand carry the elevator car 6 and on the other hand, the counterweights 15.
  • the elevator car 6 is guided as usual along rails, which are anchored to the lift shaft wall, but are not shown here.
  • the elevator car 6 can be moved past in the example shown on this drive unit.
  • a wall portion 18 of the elevator car 6 can be removed, and then the access to parts that need to be serviced, for the service personnel 20 is ensured, so that the maintenance of him from the elevator car 6 can be handled out, as in WO 2008 / 095324 is described in detail.
  • the shaft doors 1 1 to 13 with the exception of those 14 of the uppermost access level 4, can not be opened as long as the elevator car 6 stops on the corresponding level of access.
  • the shaft doors can usually be unlocked and opened with a triangular key. Depending on where the elevator car is currently located, you can then look at it from above with the shaft door open, or from below onto the lift cabin above, and access to the elevator shaft is possible through every shaft door, including access to the elevator shaft Lift shaft below the elevator cabin.
  • the technical precautions consist in that at least the shaft door 11 is always locked when the elevator car 6 is not exactly on the respective access level. So only if the elevator car 6 stops, for example, on the access level 1, the shaft door located there 11 can be opened. At least the lowermost shaft door 11 has even deliberately no emergency release at all and can therefore never be opened from the outside if the elevator car does not stop in front of this shaft door 11.
  • the elevator car 6 can only drive away when the previously open shaft door 1 1 is initially closed and locked again.
  • the chute door 11 only provides access to the interior of the elevator car 6, but never into the interior of the elevator shaft 17 above or below the elevator car. Only one or more shaft doors 12-14 above the lowermost shaft door 11 not only allow access to the interior of the elevator car 6, but also access to the area above the elevator car 6 each after whether these landing doors 12-14 have an emergency release or not. Of course, the access into the elevator cabin 6 makes it possible for the elevator car 6 to stop on one of the access levels 2-4.
  • the respective shaft door 12-14 makes it possible to access the elevator shaft 17 by means of a dedicated emergency release, if available, but only in the area above the lift cabin 6, but never below it!
  • a dedicated emergency release if available, but only in the area above the lift cabin 6, but never below it!
  • an emergency unlocking shaft door 12 directly above the bottom shaft door 11 and a position of the elevator car 6 above the shaft door 12 for example, access to the elevator shaft 17 is also impossible, as a fall into the pit not to be understood as access to the elevator shaft is.
  • the elevator shaft 17 is thus accessible only via upper shaft doors 12-14, by means of an emergency release, which is deliberately not present at least at the lowest shaft door 11. None can happen at all below the lift cabin 6, because this area is never accessible for technical reasons, and a shelter below the elevator cabin 6 is therefore unnecessary!
  • the service staff is located on the cabin with sufficient shelter or appropriate protective measures, or only inside the elevator cabin 6, which also forms the permanent shelter!
  • the special feature of a permanent shelter is that in the elevator cabin the full protection is guaranteed always and everywhere, without any measures that are to be taken first, and without any special precautions or changes that must occur first.
  • a shelter on the other hand which only partially protrudes into the elevator cabin, is considered to be a temporary and therefore not a permanent shelter, because at first something has to happen on the roof of the cabin so that it arises. Also, only a temporary shelter is present when, for example, a safety circuit must first be activated, or a drive must be blocked, or a support must be inserted or folded down, or any other measures must be taken to ensure the presence of a shelter.
  • one or more shaft doors 12-14 have an emergency release above the shaft door 11 of the lowest access level 11.
  • only the uppermost shaft door 14 has an emergency release.
  • all shaft doors 11-14 are permanently lockable. at This embodiment is neither an access below the elevator car 6 in the elevator shaft pit still access above the elevator car 6 in the elevator shaft 17 possible. For maintenance purposes, only the inside of the cabin can be reached. Accordingly, the elevator car 6 has a maintenance opening in order to allow maintenance work from the cabin interior of the elevator car 6.
  • further shaft doors 12-14 can be permanently locked. Accordingly, these additionally permanently lockable shaft doors 12-14 open only when a lift cabin 6 moves in the area of the respective access level 2-4 or holds on this level of access 2-4. Those shaft doors 12-14, which have an emergency tread, then give access to the elevator shaft 17 to the area above the elevator car 6 free, when the elevator car 6 is positioned on a development level 11-13 below the respective shaft door 12-14.
  • the shaft door 11 Due to the design, at least the lowest shaft door 11 can not be unlocked, if the elevator car 6 is not at the height of the relevant shaft door.
  • one or more upper shaft doors 12-14 are unlockable from the outside, depending on whether they have an emergency release.
  • the shaft door opens in a conventional manner. In this state, the service personnel can enter the interior of the elevator car 6 and check everything at the shaft door and the elevator car door, which is also visible to the ordinary lift user. However, the service personnel can not check or repair at least the mechanics and control of the shaft doors 11 in this position of the elevator car.
  • the elevator car 6 for example, have a removable ceiling, wall or light part, behind which hides the control it lift drive for the service mode, for example in the form of a stationary control bar, or a removable control bar that hangs on a cable, so the service personnel gets freedom of movement and can be located in any position inside the closed elevator car and still be able to easily operate the controller and drive up and down in the service mode.
  • the control unit can also be installed in a niche in the interior of the elevator cabin, which can be closed by a sliding or hinged door, or by a separate, attachable cover.
  • the control unit can also be realized by Slots are provided on the inside of the elevator cabin, for example, USB slots.
  • the service personnel then bring their control unit, or such is deposited at a suitable location in the elevator, and it then makes the electrical connections to the drive and its control electronics through the slots, so that it can drive up and down in the closed elevator cabin in the service mode .
  • the control unit can also be implemented wirelessly.
  • the service staff will then have an encoder which acts via a wireless interface on the lift cabin.
  • the control unit for driving the closed elevator car in the service mode can also function by a specific combination of keys on the already existing key board, or by specific key combinations on a separate, hidden in the elevator cabin in a niche key board.
  • the service mode allows you to drive the lift as slowly as you like and stop it at any point.
  • the service personnel from a certain level of access in service mode from the closed elevator cabin can slowly ramp up something, for example, about one meter, and then open the elevator car door. It is located directly in front of the shaft door drive in the upper area of the shaft doors of the associated access level.
  • the shaft doors are now slightly lower down the elevator car and service personnel are given ideal access to all components of the landing door drive. If necessary, it can close the cabin door again and drive up or down a few inches, to any point it desires. And at any desired point, the lift cabin doors can be opened again later and work carried out. And should fall for some reason, an object between the car door and the shaft door in the elevator shaft, it can be recovered by the fact that the bottom of the elevator car 6 from the elevator cabin can be partially or completely removed.
  • the floor of the elevator cabin can have slides or folding doors which can be opened into the elevator cabin 6, so that the entire elevator shaft floor can be reached with a tool and objects can be retrieved from it. Even if, for example, a liquid was spilled, or oil would have run out, it could easily be removed through this opening hatch from the bottom of the shaft.

Abstract

L'ascenseur selon la présente invention ne comporte pas de cuvette de gaine d'ascenseur, ou une cuvette d'une profondeur minimale lorsque la cabine se trouve au niveau d'accès le plus bas, mais répond néanmoins aux prescriptions de l'ordonnance sur les ascenseurs concernant les espaces libres destinés à la protection contre l'écrasement. La cabine d'ascenseur (6) est déplaçable dans une gaine (17) dotée de portes palières (11-14) sur plusieurs niveaux d'accès (1-4). Les travaux de maintenance peuvent être effectuées aussi bien sur la cabine d'ascenseur (6) que depuis l'intérieur de celle-ci. La particularité réside en ce que l'accès à la zone (17) située sous la cabine d'ascenseur (6) est rendu impossible. À cette fin, au moins la porte palière (11) la plus basse est verrouillée de manière permanente, tandis que toutes les portes palières (12-14) des niveaux supérieurs peuvent être équipées d'un système de déverrouillage de secours. Ladite au moins une porte palière (11) la plus basse est ainsi verrouillée en permanence, sauf dans la situation dans laquelle la cabine (6) est sur le point de s'arrêter ou est arrêtée en face d'elle. L'espace de sécurité permanent (F) est constitué de tout l'intérieur de la cabine d'ascenseur (6) elle-même.
