Definitions

  • the invention relates to a lift cabin with side maintenance window according to the preamble of claim 1.
  • Lifts must be regularly inspected and maintained to ensure adequate safety.
  • elevator components such as guides of counterweights, guides of the elevator car, trolleys, suspension cables, etc. must also be checked, which often run at least partially in the elevator shaft to the side of the elevator car.
  • a lift drive can be arranged laterally next to the elevator car in the elevator shaft.
  • a lift fitter can use the maintenance window to access the components on the corresponding side of the elevator shaft from the inside of the cabin check and if necessary to wait.
  • a corresponding maintenance window is for example from the WO 01/79104 A1 known. In this case, the lift fitter first drives the elevator car to a desired location and then opens the maintenance window to perform the required maintenance.
  • WO 2008/074167 A1 describes a lift cabin with maintenance window, in which a barrier is to ensure that the required safety distances are maintained.
  • the maintenance window is closed by a removable panel.
  • the panel is parked by the lift fitter after removal on the cabin floor and leaned as a safety barrier to the cabin wall, in which the maintenance window is formed.
  • a spacer such as a handrail is provided which determines a distance of the panel from the cabin wall.
  • a revision drive is released.
  • the security device does not ensure that the barrier is properly located and forms a safety barrier.
  • the barrier could fall over during the journey, if they z. B. is not properly hung on the handrail. Since only one position on the panel can be checked via the connection of the cable, the panel can, for. B. may be ajar, so that is fallen below on one side of the safety distance. The lift mechanic is thus exposed to unnecessary risks, since under certain circumstances, a revision drive is feasible with connected to the security device, but not correctly arranged barrier.
  • WO 2008/095324 A1 discloses a lift cabin with maintenance window.
  • This object is solved by the features of claim 1.
  • This relates to a lift cabin with a side maintenance window and a panel which covers an opening of the maintenance window openable in a normal position.
  • a spacer in particular when the maintenance window is open, can be brought into a maintenance position in the maintenance window in such a way that a barrier is provided at a safe distance from passing elevator components.
  • a safety device monitors whether the panel is in the normal position and whether the spacer is in the maintenance position.
  • the invention is characterized in that the safety device blocks a normal drive and a revision drive the elevator car when the panel is not in the normal position and the spacer is not in the maintenance position.
  • a revision drive can only be released by the safety device if the spacer is in the maintenance position.
  • the revision drive is automatically released when the spacer is in the maintenance position.
  • no further manipulations such as. B. the transfer of a released only in the maintenance position lock switch by the lift mechanic required.
  • the inventive solution has the advantage that a revision ride is only released when the spacer is actually in a maintenance position in which there is a barrier with safety distance.
  • the spacer z. B. automatically locked.
  • the spacer can be locked manually, z. B. by tightening a screw or inserting a cotter pin. But even without detection sufficient security is ensured according to the invention, since the revision drive would be interrupted immediately if the spacer deviates from a maintenance position. It is understood that in principle also several maintenance positions or a range of maintenance positions can be provided, in which a barrier is ensured with a sufficient safety distance.
  • the spacer may, for. B. be formed as a separate plate element or bracket element, which in the maintenance position z. B. is inserted from the inside of the cab in corresponding brackets of the elevator car. For this purpose, the spacer z. B. stowed in the elevator car. Likewise, the spacer may be attached to the elevator car and in the maintenance position z. B. be pivoted in the cabin interior. It is understood that the safety distance and a height above the cabin floor of the barrier provided by the spacer can be largely freely selected according to the requirements or the regulations.
  • the safety device comprises a first safety contact, which can be activated by bringing the panel into the normal position.
  • the safety contact can for example be designed as a switch or as a button, but also be activated magnetically or in another way.
  • the safety contact is as simple and robust as possible.
  • the first safety contact can be activated directly by the panel, if this comes to the normal position or is arranged in this. Basically, a simple electrical contact button is conceivable, which is closed when inserting the panel in the maintenance window.
  • a locking device is also present, via which the panel can be locked in the normal position, such.
  • the first safety contact can also be activated only via the locking device when the panel is locked in the normal position or is.
  • the panel may be designed, for example, as a one-part or multi-part pivoting wing.
  • the panel is designed to be removable for opening, so that an opening of the opened maintenance window is completely released.
  • the safety device comprises a second safety contact, which can be activated by the spacer is brought into the maintenance position.
  • the second safety contact can be designed largely analogously to the first safety contact.
  • the second safety contact is preferably activated directly by the spacer when it enters the maintenance position or is arranged in this.
  • a safety contact instead of a safety contact, other monitoring devices may be provided for both the panel and the spacer. For example, it could also be determined via optical or acoustic sensors whether the panel is in the normal position or the spacer is in the maintenance position.
  • the spacer is designed such that it is arranged in the maintenance position largely perpendicular to the cabin wall, on which the maintenance window is formed.
  • a size of the spacer can be used to the maximum.
  • this can also be arranged at any angle. It is conceivable z. B. arranged below the maintenance window, with an upper edge in the cabin space einschwenkbares further panel.
  • an arrangement of the spacer in which the spacer protrudes in the maintenance position through the maintenance window in the cabin interior.
  • fastening or holding means can be arranged outside the cabin interior, where they are accessible from the cabin interior only after the opening of the maintenance window.
  • the spacer is movably supported on the elevator car. He is in particular from the maintenance position in a rest position can be brought (and vice versa).
  • the spacer may be designed extendable, z. B. in the rest position, d. H. in normal operation of the lift, serve as a handrail, which can be pulled in the case of maintenance in longitudinal guides in the cabin interior in the maintenance position.
  • the spacer is designed as part of the cabin wall which can be pivoted into the cabin interior, z. B. as another panel.
  • the spacer can also be supported so movable that it is fixed in the rest position and the maintenance position each rigidly to the elevator car and is only movable to the transition from one to the other position.
  • the spacer between the rest position and the maintenance position is pivotally mounted on the elevator car.
  • the spacer is pivotable about a direction substantially parallel to the cabin floor and the cabin wall direction.
  • the spacer can be arranged in the rest position, for example, particularly space-saving parallel to the cabin wall, while it is pivoted in the maintenance position in the cabin interior.
  • the spacer in the rest position is advantageously arranged such that it can be covered by the panel when it is brought into the normal position.
  • the spacer may also be designed as a fold-out element of an inner wall lining of the cabin wall, for example as a fold-out bracket.
  • the spacer extends at least over the entire width of the clear opening of the maintenance window.
  • Width refers to a dimension in the direction parallel to the cabin wall and the cabin floor. In this way, it is ensured that it is not possible to fall below the safety clearance provided by the spacer from the position of the cabin interior to the maintenance window.
  • the spacer can be designed in different ways.
  • the spacer comprises a bracket, which is in particular U-shaped.
  • the bracket can be supported at its free arms in pivot bearings on the elevator car.
  • the bracket is mounted in a rest position in corresponding supports and arranged with the bracket plane largely parallel to the cabin wall.
  • the bracket can be attached via bolts in a maintenance position to a support structure of the elevator car, in which it protrudes largely perpendicular to the cabin wall in the cabin interior.
  • B. wing nuts are used, with free ends of the bracket can be angled to provide a good mounting surface.
  • the spacer is designed and arranged in the maintenance position such that the safety distance provided by the barrier to the car wall or to the passing elevator components is ensured at a predetermined height above a floor of the elevator car. It is understood that the barrier can extend to the floor at a constant distance and not only ensures the safety distance at a certain height.
  • the invention also relates to a lift, z. B. in a building, with a lift cabin as described herein.
