Definitions

  • the invention relates to a construction elevator with a vertically erectable elevator mast and with an elevator car that can be moved along the elevator mast in the vertical direction and has at least one motor drive with control.
  • Construction lifts of this type are known as passenger lifts or freight lifts, with the elevator cars being designed differently depending on the transport load (people or loads).
  • the elevator mast is usually to be anchored at the installation site on the floor surface, for which purpose it is equipped with an elevator platform which usually consists of a frame and which is set up on the floor surface and anchored if necessary.
  • the elevator platform is usually provided with a fence-like encirclement, which makes access to the platform impossible if the elevator car is not in the lowest position.
  • a construction elevator is known for example from DE 196 13 308 AI. - 2 -
  • Such protection of the elevator platform is relatively complex, namely both when setting up and dismantling such a construction elevator, and it can make access to the elevator car more difficult, in particular if the elevator car is designed as a load carrier. It is also necessary to have different containment sizes available for elevator cabins and elevator car platforms of different sizes.
  • the object of the invention is to further develop a construction elevator in such a way that it is ensured in the simplest possible way that no persons or objects can be located below the elevator car when the elevator car is descending.
  • This object is achieved according to the invention with a construction elevator of the type mentioned at the outset in that it is equipped with an optical monitoring device which acts on the space above the elevator platform and which is connected to the control of the motor drive in such a way that the motor drive can be stopped at least when the elevator car is moving downwards is when the space above the elevator platform is not free.
  • a particularly preferred embodiment is characterized in that the monitoring device is formed by light barriers, which are preferably designed as infrared light barriers.
  • the light barriers are arranged at least in regions around the outer edge of the elevator platform. It may be sufficient that light barriers are provided on two opposite outer edges of the elevator platform.
  • the light barriers are integrated in a frame element which is attached to the edge of the elevator platform.
  • existing construction lifts can also be retrofitted particularly simply by simply mounting a corresponding frame element equipped with light barriers on the edge of the elevator platform.
  • the light barriers are integrated in the elevator car.
  • At least one laser scanner can also be used as the optical monitoring device instead of light barriers.
  • a laser scanner is known, for example, from the magazine F + H Report 1994, Oct., pp. 46, 48 "Programmable laser scanner revolutionizes accident protection".
  • Fig. 1 shows a perspective view of an embodiment of a construction elevator according to the invention
  • Fig. 2 is a side view of a construction elevator, which is shown without a cabin.
  • FIG. 1 A construction hoist is shown in FIG. 1 only with the parts essential to the invention and is generally designated 1.
  • This construction hoist 1 initially has one at the installation site at the construction site or the like. on the floor surface to be set up, consisting of a base frame, on which an elevator mast 3 is preferably arranged in a corner area, - 6 -
  • an elevator car 4 can be moved, which in the exemplary embodiment shown is designed as a closed passenger elevator car.
  • the elevator mast 3 can be equipped, for example, with a toothed rack and the elevator car 4 with a motor drive, not shown, designed as a geared motor, with appropriate control.
  • the construction elevator 1 is provided with an optical monitoring device which acts on the space above the elevator platform 2. - 7 -
  • this monitoring device is formed by two light barriers 5, which are arranged on two opposite outer edges of the elevator platform 2. These light barriers 5 are preferably designed as infrared light barriers. These light barriers 5 are suitably connected in a manner known per se to the control of the motor drive 7 of the elevator car 4. If, when the elevator car 4 is moving downward, it is determined by means of the barrier 5 that there are people or opponents. If changes are located above the elevator platform 2, the control of the motor drive 7 is activated such that the elevator car 4 or its motor drive 7 is stopped immediately and the elevator car 4 cannot move further down. This is only possible again when the space above the elevator platform 2 is free again.
  • the light barriers 5 are preferably integrated in a frame element 6, which can be easily attached to the edge of the elevator platform 2, which also enables existing construction elevators to be retrofitted in a particularly simple manner.
  • the light barriers 5 are not arranged on the elevator platform 2, but are integrated in the elevator car 4. - 8th -
  • the invention is not limited to the exemplary embodiments shown. Further configurations are possible without leaving the basic idea.
  • the construction of the construction elevator 1 according to the invention is of course not only suitable for passenger elevators, but also for freight elevators in which the elevator car 4 is usually designed differently and the like. more.
  • the light barriers 5 described as an optical monitoring device at least one laser scanner can also be used, which is not shown in the drawings.

Abstract

L'invention concerne un monte-charge comportant un poteau réglable verticalement et une cabine déplaçable le long dudit poteau dans le sens vertical, ladite cabine étant munie d'au moins un moteur d'entraînement avec une commande. L'invention vise à perfectionner ce monte-charge, afin de garantir de la manière la plus simple possible qu'il ne puisse y avoir de personnes ou d'objets en dessous de la cabine lorsque celle-ci descend. A cet effet, le monte-charge (1) est équipé d'un système de surveillance (5) optique qui sollicite l'espace situé au-dessus de la plate-forme (2) du monte-charge. Ce système de surveillance est relié à la commande du mécanisme d'entraînement à moteur (7), de manière que ledit mécanisme d'entraînement à moteur (7) puisse être arrêté au moins lorsque la cabine (4) descend, si l'espace situé au-dessus de la plate-forme (2) du monte-charge n'est pas libre.
