Definitions

  • the invention relates to a cable elevator system with an elevator car which can be moved along spaced-apart car guide rails by means of a drive motor having a traction sheave for a car cable and which is connected by means of the car cable to a counterweight which can be moved along spaced-apart counterweight guide rails.

  • DE 1 740 974 describes a cable lift system, ie an engine arrangement for such a system, in which the engine is accommodated in an independent box-like frame construction.
  • This drive arrangement is characterized in that a vertical, closed, approximately rectangular frame is connected on one side in its upper part with a box-like frame for receiving the drive with the drive motor, controller, switching elements, cable guide, etc., on the side of the elevator shaft outside the same, and on the the the drive

  • the car guide rails span a first level that runs alongside the elevator car.
  • the training with corner stands and with cross struts, which connect the corner stands to the elevator scaffold, results in a considerable expenditure of material and assembly.
  • the counterweight guide rails are attached to the U-brackets in this known elevator installation in such a way that they span a second plane perpendicular to the first plane.
  • the counterweight guide rails are provided on one side of the U-bracket, so that the space available for the counterweight in the projection area is limited to the elevator shaft floor.
  • the invention has for its object to provide a cable elevator system of the type mentioned, which can be easily formed with a counterweight of the desired mass with a simple structure.
  • This object is achieved according to the invention in a cable-and-elevator system of the type mentioned at the outset in that the car guide rails lie opposite one another at the side of the elevator car, so that the first level extends through the elevator car in that the one guide rail follows the car guide rails from the portal device stands at the top and is shortened accordingly in length, and that the cable traction sheave is oriented perpendicular to the first plane spanned by the cabin guide rails, the second plane spanned by the counterweight guide rails being oriented perpendicular to the first plane and separated from the cable Traction sheave axially spaced is provided on the side of the cable traction sheave facing away from the drive motor.
  • the inventive design of the cable elevator system has the advantage that the path of the counterweight is not hindered by the drive motor, so that the height of the counterweight can be made comparatively long. This means that the corresponding additional space is available for additional counterweight inserts which are required for larger elevator car weights for the purpose of weight compensation.
  • the portal device can have a base plate, from which a pair of front and a pair of rear pillars stand upwards, the respective front and rear pillars Stand column is connected to one another on the top side by means of an associated first connecting element, and the drive motor is fixed on the base plate and between the two front stand columns.
  • This definition can be realized by screwing.
  • the pillars and the two first connecting elements can be designed as profile elements in order to be able to achieve the desired mechanical stability with the lowest possible weight.
  • Cross member is attached to which the shortened first guide rail is attached with its lower end portion.
  • This cross member can be designed as a gusset plate, which is welded to the two connecting elements, for example.
  • the shortened first guide rail is expediently fastened to the cross member by screw connections.
  • the second guide rail which extends as far as the elevator shaft floor, can have at its lower end a base element which is connected to the base plate of the portal device by means of a connecting part.
  • This can be a one-piece design, in which the base element, from which the second guide rail stands upwards, the base plate of the portal device and the connecting part provided between them are integrally connected to one another or formed.
  • the base surface element and the base plate at their mutually facing edge sections and the one provided between them Connection part are formed with mutually adapted positive locking elements.
  • These can be dovetail recesses on the edge sections of the base element and the base plate and dovetail end sections of the connecting part which are matched thereto, or any other form-fit elements which form suitable undercuts.
  • a suitable fixation of the base element and the base plate to the building floor means that intercepting forces are easily absorbed upwards and dissipated in the building floor.
  • the relatively long second guide rail is connected to the portal device and thus to the first guide rail, which is shortened in comparison to the second guide rail, the particular advantage being that assembly is simple because the so-called pitch dimension, i.e. the distance between the two guide rails from each other is automatically determined by the connecting part. This advantageously means that installation is easier.

Abstract

L'invention concerne un système d'ascenseur à câble (10) comportant une cabine d'ascenseur qui peut se déplacer le long d'un premier et d'un deuxième rail de guidage (12, 14) se faisant face latéralement, au moyen d'un moteur d'entraînement (20) présentant une poulie motrice (22) pour un câble de cabine. La cabine d'ascenseur est reliée à un contrepoids. Le moteur d'entraînement (20) est placé à l'extrémité inférieure de la cage d'ascenseur (26), à l'intérieur des surfaces de projection (28), délimitées par les rails de guidage (12, 14), de la cabine d'ascenseur sur le fond de la cage d'ascenseur (26). Ce moteur d'entraînement (20) est placé sur un ensemble portique (18) à partir duquel, le premier rail de guidage (12), raccourci d'une valeur équivalente à la hauteur dudit ensemble portique (18), s'étend verticalement vers le haut. La poulie motrice à câble (22), raccordée au moteur d'entraînement (20) de façon à transmettre le couple de rotation, est située sur le deuxième côté (30) du moteur d'entraînement (20), opposé au deuxième rail de guidage vertical (14).
