Definitions

  • the invention relates to an elevator installation for the transport of loads and / or persons in a lift shaft with the features of the preamble of claim 1.
  • a longitudinal guide rails movable elevator car is for example from the international publication WO 98/39242 known.
  • a support frame is provided for holding the elevator car to the guide rails, on which the elevator car is placed.
  • the elevator car is associated with a hydraulic cable drive with a hydraulic lifting cylinder, which is arranged between two guide rails.
  • the guide rails are held on a wall of the elevator shaft at a distance to this and are based directly on the bottom of the elevator shaft.
  • an elevator system in which the elevator car is held movable on two guide rails. Between the bottom of the elevator shaft and the bottom end of the guide rails, a receiving space is arranged for receiving a drive device in order to save installation space in this way.
  • the drive means is adapted to the design of the guide rails so that their width substantially coincides with the distance of the guide rails and their depth corresponds to practically the depth of the used counterweight.
  • the guide rails are in this case set in the vertical direction at a distance from the drive device in the elevator shaft.
  • Object of the present invention is to provide an elevator system of the type described above in such a way that it is inexpensive to produce and assemble, where it requires a small installation space.
  • An elevator system with such a configuration requires only a relatively small installation space. At least parts of the drive can be positioned below the guide rails, wherein at the same time it is ensured by the use of the support structure that the guide rails in a structurally simple, yet reliable manner in the elevator shaft can be fixed.
  • the weight of the guide rails and the forces acting on them by the elevator car are in this case essentially taken up by the support structure, so that additional holding means for aligning the guide rails within the elevator shaft, for example, retaining clips or brackets, structurally simple and inexpensive to manufacture can be configured.
  • the formation of a receiving space below the guide rails has the advantage that the positionable in the receiving space parts of the drive can be selected independently of the distance of the guide rails from each other and their distance from the shaft wall.
  • the drive means and the drive control are arranged at the level of the lowest holding position of the elevator car.
  • the drive means is received by the receiving space of the support structure and is thus positioned within the elevator shaft, while the drive control is positioned in a recess laterally next to the elevator shaft.
  • Drive means and control are thus arranged in the region of the lower end of the elevator shaft at the level of the lowest station of the elevator installation and thereby accessible in a simple manner for maintenance.
  • the installation of the elevator system is considerably simplified in such a positioning of the drive parts.
  • the elevator car can thus be positioned at the height of the receiving space.
  • a shaft pit receiving the drive device for the elevator shaft can therefore be dispensed with, as a result of which the design measures for installing an elevator installation in a building are considerably reduced. It can namely be provided that the elevator shaft extends downwards only to such a height that the cabin floor of the elevator car can be positioned at the level of the lowest floor of the floor.
  • the invention provides that the drive at the upper end of the elevator shaft comprises pulleys, which are arranged outside the path of the elevator car.
  • the elevator car can be positioned laterally next to or between the deflection rollers in its uppermost holding position.
  • a separate shaft head which extends above the ceiling of the uppermost floor, which is to be reached by the elevator installation, can be dispensed with for the elevator shaft. The cost of installing the elevator system in a building can be significantly reduced.
  • the elevator car is held displaceably by means of guide elements on the guide rails, wherein lower, the cabin floor associated guide elements are arranged offset in the vertical direction with respect to the cabin floor upwards.
  • the lower guide elements are thus arranged at a distance from the cabin floor, so that a gap remains free, which can be used for positioning of parts of the drive.
  • the cabin ceiling of the elevator car associated upper guide elements are arranged offset in the vertical direction relative to the cabin ceiling upwards, so that the greatest possible distance between the lower and the upper guide elements results, whereby the synchronization of the elevator car along the guide rails is improved.
  • the elevator car comprises buffer elements which can be placed on the support structure to limit the downward movement of the elevator car.
  • the support structure not only assumes the function of supporting the guide rails in the vertical direction, but it also serves as a support for the elevator car when the elevator car continues to lower starting from its lowest holding position.
  • the support structure may advantageously comprise a support element supporting the guide rails and optionally also the elevator car, for example in the form of a support plate, and the support element supporting support base at the bottom of the elevator shaft.
  • the support structure thus forms a stand on which the guide rails can be placed and on which the buffer elements of the elevator car can hit during the downward movement.
  • the support structure can be fixed solely to the shaft wall without supports to the ground, the space for receiving drive parts is still larger.
  • the drive comprises a traction sheave drive with a traction sheave and a counterweight.
  • a traction sheave drive with a traction sheave and a counterweight.
  • at least one traction sheave is within the receiving space arranged.
  • the counterweight is advantageously positioned between or adjacent to the car guide rails.
  • the drive comprises a drum drive. It is advantageous if the drum drive comprises at least one arranged within the receiving space drive drum. It is particularly advantageous if the drum drive comprises two drive drums arranged in the receiving space. It can be provided that the two drive drums are rotatable about a common axis of rotation. The latter can for example be aligned perpendicular to the shaft side walls of the elevator shaft.
  • a particularly space-saving arrangement can be achieved in that the two spaced apart within the receiving space arranged driving drums are coupled to a drive motor which is arranged between the two drive drums within the receiving space.
  • the receiving space may include transmission and / or brake elements connected to the engine and / or drive drums.
  • the associated drive or elevator control can be arranged directly above the drive between the guide rails, where it can be reached through an opening in the shaft wall.
  • connection of the drive device with the elevator car can be done by means of suspension cables. It is to achieve a particularly space-saving design of the elevator system advantageous if the Support cables run laterally next to and / or behind the elevator car. This has the advantage that the elevator car can be moved along the entire zugsschachtes on.
  • a further saving in installation space can be achieved in that the elevator car is a car door and a cabin rear wall opposite the car door comprises, wherein the elevator car tapers in the direction of the cabin rear wall.
  • This allows a configuration in which the width of the elevator car in the region of the car door substantially corresponds to the width of the elevator shaft, while a smaller width is selected for the area of the cabin rear wall so that a free space remains in the rear area between the elevator car and the shaft side walls. for example, allows the positioning of pulleys and / or support cables laterally next to the elevator car.
  • the embodiment of an elevator car with an outer contour seen from above in the form of a substantially isosceles trapezoid has proven to be structurally particularly advantageous.
  • the drive comprises supporting cables, which are fixed via a lever mechanism to the elevator car, wherein the lever mechanism is coupled with a slack rope and / or overload monitoring for stopping the drive of the elevator car when slack or Overloading the suspension cables.
  • the lever mechanism in particular allows a suspension of the elevator car in or near its center of gravity.
  • the elevator installation according to the invention is characterized in particular by an optimized use of space.
  • the elevator car has at least one wall part which is designed to be at least partially transparent and also air-permeable.
  • the wall part can be made for example of a perforated plate.
  • Such a configuration has the advantage that a good ventilation of the elevator car is ensured without additional ventilation devices.
  • the use of the perforated plate enables partial transparency of the walls delimiting the elevator car laterally, by means of which the user is given the feeling of a generous design of the elevator cage.
  • at least two opposing side walls of the elevator car are made of perforated metal. Additionally or alternatively, it may be provided that also perforated plate is used for the design of the cabin rear wall and / or the cabin ceiling.
  • the elevator car is preferably held in a suspended arrangement on a support frame.
  • a support bracket in backpack design can be used with a horizontal support extending above the car ceiling and a vertical support extending parallel to the guide rails.
  • the vertical support in this case allows a mechanically stable guidance of the elevator car to the guide rails, and the use of the horizontal support makes it possible to set the elevator car on a support cable so that tilting moments are reduced to a minimum, since the force attack on Support frame can be made in height of the center of gravity of the elevator car.
  • the attachment of the cabin can be made such that the back of the cabin floor is attached to the vertical support and the front part of the cabin with the load-bearing cabin floor on the cabin walls and / or the car door or hanging on the cabin walls and / or the car door parts , z. B. at the door portals.
  • a cabin apron is arranged on the elevator car below the threshold of the car door. It is particularly advantageous if the extent of the cabin apron in the vertical direction between a maximum length and a minimum length is variable. It may preferably be provided that the cabin apron automatically assumes its minimum length when retracting the elevator car in its lowest holding position and automatically moves into the maximum length when extending from the lowermost holding position. Such a construction makes it possible to provide a cabin apron during the travel of the elevator car, the length of which fulfills the safety requirements and, for this purpose, protrudes more than 50 cm, in particular approximately 75 cm, from the cabin floor.
  • the length of the cabin skirt automatically to a minimum length, which preferably corresponds to less than 20 cm, in particular about 10 cm.
  • a minimum length allows the use of a cabin apron even in the event that the elevator shaft has not significantly below the lowest floor of the building floor extending pit.
  • the length of the cabin apron increases until it has reached its maximum length at a predefinable distance to the lowermost holding position. This maximum length can be maintained during the further journey of the elevator car.
  • a particularly advantageous construction is characterized in that the cabin apron has a fixed skirt portion and a variable in length in its vertical direction apron part.
  • the cabin apron is formed in two parts, wherein a minimum length is predetermined by the fixed skirt part, while the variable skirt part defines the maximum length of the cabin apron.
  • the cabin apron in the bottom region of the elevator shaft is associated with a apron Aufsetzpuffer on which the cabin apron when retracting the elevator car can be placed in its lowest holding position, so that the cabin apron assumes its minimum length.
  • the cabin apron may, for example, have a scissors joint.
