Definitions

  • the present invention relates to a room-less equipment for persons and goods particularly suitable for limited pay-load, speed and car travel.
  • the hydraulic lifts needs an additional space where to locate the pump unit and, as far as the electric lift with lifting ropes is concerning, the geared motor with the traction pulley which has got to have a diameter of 40 times that of the traction ropes, by all the existing codes, requires a considerable reservation of space inside or outside the lift well; last but not least the a.c. geared motor cannot operate in the case of a power failure and, hence, doesn't allow any automatic rescue operation if passengers are trapped in the car because of that.
  • the present invention has been developed with the aim of overcoming the above drawbacks of the prior art.
  • the general purpose of present invention is to realize a machine room-less lifting equipment having the following improved characteristics:
  • the room-less lifting equipment for persons and goods comprises:
  • a room-less lifting equipment as above described, with:
  • the cabin and its frame form a compact structure having as upper side a console-wise beam 17, which holds the total load.
  • This compact structure consents to minimize both its weight and the depth of the pit (indicated with 19 in Fig. 1b), so allowing the access to the car from the lower floor through a ramp (indicated with 20 in Fig.1b) not higher e.g. than 50 mm from the basement floor, being 50 mm the depth of the pit.
  • the self-supporting, cantilever type, chassis consists of a bolted metal frame where the upper console-wise beam holds the loading platform through four uprights which represent the four corners of the car-cage.
  • the upper beam incorporates the idle pulleys on which the total load is hauled by the traction belts.
  • the two uprights in correspondence of the car guide rails are fitted with shoes which guide the car along the hoistway on the relevant guide rails.
  • Fig.4 shows a preferred embodiment of the two hauling belts 3.
  • any belt comprises a polyurethane covering embedding a number of metal wires 23 positioned parallel to the sides of the belt and connected in serial at the two ends of the belt.
  • the number of metal wires and their diameter are calculated in accordance with the indication of EN81-1, which represents the European code for the lifts.
  • the integrity of the metal wires, embodied into the toothed belt, is permanently monitored by a detecting circuit.
  • the two terminals of the metal wires series are serially connected to a voltage feeder 24 and to a detector circuit 25. If the wire chain becomes interrupted by a broken wire, the detector emits alarm signals and switches off the traction motor.
  • Fig.5 is a perspective enlarged view displaying the upper and lower parts of the lifting equipment of figs.1a-1b in more details.
  • this figure 15 represents a tensioner, a device which is normally associated to a speed governor (see speed governor 5), while 11 (even isolately represented in Fig.5a for a better comprehension) represents a fastening device 11 which ensures the anchoring of the diverting pulleys 10 to the upper beam 17 of the load car.
  • every diverting pulleys 10 is supported by a rocker bearing 18 which can pivot on a shaft 21, fixed to the upper beam 17.
  • a spring device prevents an excessive pivoting of the rocker bearing caused by value variations of the load, as long as the value of the load supported by the pulley remains in a regular range.
  • the rocker bearing pivots in clockwise or counterwise direction activating one of two different switches, which immediately prevents the gear motor from moving.
  • Figs.6a, 6b, 6c show side views of fastening device 11 displaying the position of the rocker bearing 18 in case of normal load (Fig.6a), or in case of belt slack (Fig.6b), or in case of overload (Fig.6c).
  • FIG.7 Another preferred embodiment is represented in Fig.7.
  • This figure shows a bar 22 installed over the traction pulleys near the houling belts.
  • This bar represents a safety provision foreseen in order to prevent possible slippings of the belts out of the pulleys due to possible shocks whatsoever caused during the car motion.
  • a variant could concern the number of the hauling belts which could be more than two.
  • FIG.3a Another variant could e.g. concern the arrangement of the belts which instead the one of Fig.3a could be the one of Fig.3b, i.e. without the diverting pulleys 10 and 12b, being the ends of the belts directly attached to the load car and to the counterweight (this means, for a same speed and a same load of the car, a sliding speed of the belts which is an half the one of Fig.3a and a load of the belts which is twice).
