Definitions

  • the present invention relates to a carrier unit for an elevator installation.
  • the carrier unit is used to attach a deflection roller to a support structure, as it can be used in particular for supporting a car or a counterweight in an elevator system.
  • the invention relates to an elevator installation with such a carrier unit.
  • Elevator systems typically comprise at least one elevator car and one counterweight, which are arranged in an elevator shaft and can be moved in opposite directions.
  • the elevator car and the counterweight are held or moved by means of one or more suspension means, for example in the form of ropes or straps.
  • the suspension elements are usually connected at their ends to a fixed structure within the elevator shaft and run around deflection rollers, which are fastened as part of a carrier unit to a carrier structure of the elevator car or of the counterweight.
  • the support means can be driven by a drive, for example in the form of an electric motor.
  • a carrier unit for an elevator installation for fastening a deflection roller to a support structure which has two yoke spars and a bearing.
  • the Jochholme are arranged parallel to each other and to attach to the support structure. At least portions of the deflection roller are arranged in a space between the Jochholmen.
  • the deflection roller is rotatably supported by means of said storage with respect to the Jochholme.
  • the Jochholme, the guide roller and the bearing are adapted to transmit a suspension by the support means on the pulley carrying capacity in an upwardly directed support direction on the support structure to carry a fixed to the support structure mass against a gravitational force or move.
  • the carrier unit is characterized in that at least two retaining fuses are further provided on the carrier unit, which are each attached to the Jochholmen and which protrude into the space between the Jochholmen such that they form a stop in case of failure of the storage to the deflection roller to prevent a movement caused by the carrying capacity in the supporting direction.
  • the retention restraints should be designed as far as possible in terms of their positioning and in terms of their mechanical strength such that they protrude into the space between the Jochholmen, in which the deflection roller is arranged, such. in the event that the pulley dissolves from its storage, hold the pulley to the Jochholmen.
  • the retention fences and their attachment to the Jochholmen are designed such that they prevent the deflection roller at a by a load capacity of up to 250 kN, preferably at one by a by a load between 20 and 210 kN, effected movement in the supporting direction.
  • the restraint restraints should be designed in terms of their mechanical strength suitable that they can withstand the typically occurring in an elevator forces acting on a pulley and are normally absorbed by their storage, in case of failure of storage.
  • the restraint retainers should be sturdy enough that, in the event that the diverting pulley is no longer held by the support, they hold the diverting pulley and thus prevent it from coming off the carrier unit.
  • the retention devices are preferably attached directly to the Jochholmen.
  • the retention fences can intervene in provided in the Jochholmen holes or recesses. As a result, it can be ensured that the considerable forces that occur, for example, in the case of a bearing damage, which are then exerted on the restraint restraints by the deflection roller, are directly related to those in general be guided mechanically stable Jochholme.
  • the retention devices can be described as relatively simple components such as e.g. be formed bolt-like pins.
  • bolt-like pins in the form of screws, bolts, split pins or the like can be attached to the Jochholmen.
  • a material and a material thickness may be suitably selected to achieve required load capacities of the retention devices.
  • the retention devices may consist of metal, in particular steel or high-strength alloys. Typical material thicknesses may range from 0.2cm to 10cm, preferably 0.5cm to 3cm.
  • the retention devices are each attached to both opposing Jochholmen and each span the gap between the Jochholmen completely.
  • ends for example, bolt-like retention fuses are each attached to one of the Jochholme, so that the respective retention device is supported and held at both ends.
  • the retention devices are arranged in the supporting direction above the storage.
  • the retaining retainers may be attached to the yoke spars at a position to which the deflecting pulley moves in the event that it is no longer held by its bearing. If the bearing fails, the guide roller can thus move slightly up to the retention fences and is then prevented by these on a further movement and thus on a release of the carrier unit. The restraints are charged by the pulley primarily on pressure.
  • the deflection roller is at least approximately cylindrical and has a diameter D.
  • the retention fences should then, in relation to a direction parallel to the diameter D, protrude into the intermediate space at a distance d which is smaller than the diameter D, ie d ⁇ D.
  • the retention retainers can be arranged, for example, in the direction of support above the bearing of the deflection roller be, ie where a chord is shorter by the pulley in a direction parallel to the Jochholmen than the diameter of the pulley.
  • the retention fences can there relatively close to an outer circumference the deflection roller be arranged so that their distance d from each other in the direction parallel to the Jochholmen is shorter than the diameter D of the guide roller.
  • the distance d may be between 2% and 80%, preferably between 5% and 50%, and more preferably between 10% and 30%, smaller than the diameter D of the diverting pulley.
  • the pulley should, for example, be released from its storage, it will thus move slightly due to the forces acting on it in the upward direction of support, but then stopped by the retention fuses and quasi clamped between them. Due to their larger diameter D, the guide roller can not move between the spaced apart at the narrower distance d retention fuses and is thus held on the Jochholmen.
  • the storage is arranged below the Jochholme.
  • both the retention devices and the storage of the deflection roller are attached directly to the Jochholmen.
  • the Jochholme are preferably dimensioned so that they meet on the one hand load requirements, for example, for use within an elevator system, but on the other hand no unnecessary use of material, for example in the form of excessively wide or high Jochholme leads to unnecessary costs.
  • the storage of the deflection roller from the retention devices may therefore be advantageous to arrange the bearing of the deflection roller below the Joch bars.
  • the storage can only indirectly, i. For example, via additional intermediate elements, connected to the Jochholmen and held on this.
  • each of the Jochholme each be attached to a downwardly extending bearing support and bearings that form the storage, each attached to one of the bearing mounts.
  • the bearing mounts may be provided, for example in the form of sheets or profiles, which extend adjacent to both end faces of the guide roller and, for example, at one edge to the Jochholmen are attached.
  • the bearings can be kept in recesses, for example.
  • the bearings may be fastened to the bearing brackets, for example by means of suitable fastening devices.

  • the carrier structure 13 of the elevator car 104 has side shields 116, which are fastened at their upper ends to bars 3 of the carrier unit 1. At the lower ends of the side shields 116, a lower yoke 118 is fastened, which supports the elevator car 104 via supports 120.
  • the support means 108 extends from an end 110 fixed to the support structure 112 coming first down and then around the guide roller 5 of the counterweight 106 around, is then returned upwards to the drive unit 114, where it passes over the traction sheaves. Subsequently, the support means 108 then further extends downwardly to and around the diverting pulley 5 on the elevator car 104 and finally back up to the support structure 112, where it is fastened with its opposite end 110.
  • FIGS. 2, 3 and 4 is a support unit 1 for an elevator car according to an embodiment of the present invention in a perspective view, side view and sectional view taken along the line AA FIG. 3 shown.
  • the carrier unit described below could in principle also be associated with a counterweight.
  • the carrier unit 1 has two Jochholme 3, a guide roller 5 and a bearing 7.

  • a material thickness of the steel profile used for the Jochholme 3 can significantly more than 2mm, preferably more than 5mm, have.
  • the two Jochholme 3 are arranged parallel to each other, so that between them, a gap 11 is formed.
  • a distance between the two Jochholmen 3 and thus a width of the intermediate space 11 may for example be in the range of 5 to 50cm, preferably 10 to 20cm, so that at least portions of the guide roller 5 can be accommodated in this gap 11.
  • a plurality of sheets 15, 17 are provided, which are part of a support structure 13, by means of which the support unit 1 and in particular their Jochholme 3, for example, to an elevator car 104 or a counterweight 106 can be attached.

  • the Jochholme 3, the guide roller 5 and the bearing 7 are cooperatively designed so that a caused by the support means 108 on the guide roller 5 carrying capacity can be transmitted to the support structure 13 ultimately.
  • the carrying capacity acts in an upwardly directed support direction 31 and can typically assume values of a few kN in lift installations.
  • the carrying capacity corresponds to a counterforce which is required, for example, to hold or move a mass of the elevator car 104 fastened to the carrier structure 13 counter to a weight force. Forces, such as in particular the said carrying capacity, are within the carrier unit 1 due to a sufficient dimensioning of all supporting components, ie in particular the Jochholme 3, the guide roller 5 and the bearing 7 forming components 20 to 30, of which the guide roller 5 embracing support means 108 finally transferred to the support structure 13.
