Definitions

  • the present invention relates to an electric elevator and more particularly to an elevator system that does not require a machine room, i.e. a so-called “machine-roomless” elevator system, and utilises a traction sheave for engaging the hoist ropes, directly driven by an electric motor in a so-called “gearless” traction unit.
  • the conventional hoisting ropes elevator systems substantially comprise an elevator car and a counterweight, each one suspended at one end of a rope assembly and driven, by adhesion, through a traction sheave rotated by a winch/electric motor.
  • the elevator car and the counterweight move into an appropriate elevator hoistway or shaft and the machinery, consisting of sheave, winch/motor and braking devices, is located in a suitable room usually placed above the elevator shaft and large enough for allowing the maintenance of the equipment.
  • hoisting ropes elevator systems have been suggested (operating by adhesion/friction) that do not require a machine room but house the machinery directly in the elevator shaft.
  • the machine unit and the sheave are either located in an upper extension of the elevator shaft (in this case without obtaining the required elimination of spaces of the machine room), or in the space between the wall of the elevator shaft and the elevator car itself.
  • this solution requires the use of substantially flat machine units and/or disk-shaped rotors and arranged parallely with the sheave plane. These machinery and components are therefore of a particular type.
  • Another aspect to be considered in elevator systems without a machine room is to ensure safe operating conditions for the maintenance personnel.
  • the present invention achieves the above objects through an elevator system with a frictional traction (adhesion) arrangement which does not require a machine room and is equipped with a traction unit arranged in the elevator shaft of the elevator system, as claimed in claims 1 and 3. Further advantageous features are recited in the dependent claims.
  • an elevator system comprises an elevator car 1, moving in a hoistway or elevator shaft 2, along elevator guides 3 formed as rails. More particularly, the elevator car is carried by an independent supporting frame 5 which is projecting from the plane of the elevator guide rails and slidable along the same guides through suitable rolling or sliding shoes 15.
  • the elevator car is a box-shaped component supported by or secured to a bearing structure comprising a car frame or car cage.
  • This arrangement renders the car insulation easier, differently from what occurs in the known elevator systems where a certain integration between the elevator car and the bearing structure is provided, such as for instance a direct fastening of the shoes to the car and/or a fastening of the diverting/suspending sheaves to the bottom of the elevator car.
  • the elevator system further comprises a counterweight 4, movable along guide rails 7 and a set of hoisting ropes 6 made-up of two or more suspension and traction ropes which connect the counterweight with the supporting frame 5 of the elevator car.
  • the counterweight 4 vertically moves between the corresponding guides through suitable rolling or sliding shoes 16.
  • a traction assembly or drive unit assembly 8 illustrated more in details in Fig. 3, comprises a traction sheave 10 which transmits by (frictional) adhesion the motion to the ropes 6.
  • the diameter of the sheave 10 is such to allow nevertheless the use of conventional steel ropes and meeting the requirements of the rules in force.
  • the drive unit assembly 8 further comprises a motor 11, preferably a permanent magnet synchronous motor having a small overall diameter and a brake 13, preferably a disc brake or a shoe brake.
  • a motor 11 preferably a permanent magnet synchronous motor having a small overall diameter and a brake 13, preferably a disc brake or a shoe brake.
  • an encoder (not illustrated in the Figures), either outside of or incorporated in the motor.
  • the suspension of the counterweight 4 and of the elevator car 1 is of the tackle type and therefore the rope ends are anchored at two fixed points, one indicated by 17 and formed in a baseplate 21 on which the drive unit is mounted and the other one, shown at 18, formed on the shaft side wall which is opposite to the guides 3.
  • the car guides 3 are preferably located on the same side of the shaft 2, or in other words they lie in a plane that does not cross the elevator car 1, and this latter is cantilevered in respect the guides, an arrangement known as "rucksack" configuration.
  • the guides 7 of the counterweight substantially lie in such a plane, as better shown in Fig. 5.
  • the guides 3, 7 are secured to the shaft wall through an adjustable bracket 23 of one type only. Thanks to this arrangement, the assembling of the guides is remarkably simplified and it is possible to assemble the guides sections directly at the factory, with an appreciable saving of time and equipment for the control.
  • the plane of the elevator guides 3 and the plane of the counterweight guides 7 cross each other at 90°.
  • the suspension (diverting) sheaves of the elevator car can be mounted either at the bottom of the car, as the sheaves 19 in the Figures 2 and 4, or at the top thereof. Thanks to the type of suspension and arrangement adopted by the invention, the lifting force is applied through the centre of gravity of the elevator car and the counterweight, thus avoiding overturning torques and limiting the stresses acting onto the guides and the structures only to the dynamic loads deriving from the motion.
  • the elevator car 1 can be completely insulated from the supporting frame 5 through appropriate pads or buffers for dampening vibrations which allow a better quality of the motion in respect of the quietness and the abatement of vibrations.
  • the ceiling and/or the side wall of the elevator car is equipped with one or more easily removable panels allowing for an easy maintenance of the drive unit assembly 8 from the inside of the elevator car.
  • FIG. 9A illustrates an elevator car 1 adapted to allow interventions on the drive unit assembly from the inside of the car.
  • the elevator car is equipped with ceiling panels 25 which can be easily removed and which, in Figure 9A, are shown in their positions when the elevator is operating.
  • the elevator car can be equipped with removable side panels or wall panels, such as those indicated by 27 in Fig. 9B which panels too allow for an intervention on the drive unit assembly from the inside of the elevator car.
  • the same Figure also shows a false ceiling 26 which covers the ceiling panels and can be displaced, for example rotated, when panels 25 are to be removed.
  • Figures 10A and 10B illustrate the elevator car 1 with the panels 25 and 27 removed, and the false ceiling 26 hinged at a side and lowered to allow the access to panels 25.
  • the drive unit assembly 8 is mounted with its axis parallel to the plane of the guide rails, so that the traction sheave 10 is disposed perpendicular to this plane. Besides, the size of the unit is pretty reduced in the direction perpendicular the plane of the guide rails thus allowing a reduction of the shaft dimensions.
  • the drive unit assembly 8, as illustrated in Fig. 3, is mounted on a baseplate 21 secured through rubber dampers 22 to a pair of side supports 23 that in turn can be fastened either to the shaft wall, or only to the guide rails 3,7, or to both the shaft wall and the guide rails.
  • the baseplate 21 is secured either to the shaft wall, or to the guide rails 3, 7 only, or to both to the shaft wall and the guide rails.
  • one (17) of the fixed anchorages for the traction ropes 6 is implemented.
  • a fastening clamp 24 for clamping the ropes is provided in the baseplate 21, which is very useful during the maintenance of the drive unit assembly.
  • the elevator system further comprises a controller or control panel which houses the control system of the elevator system, the drive unit assembly of the motor and several switches.
  • such a control panel is usually located at the topmost floor, at a side of the landing door, in a suitable independent box 14 as illustrated in Figure 6.
  • a suitable independent box 14 as illustrated in Figure 6.
  • it be located at any other floor, or inside the elevator shaft, and being or not extractable.
  • it can be formed by a plurality of sub-assemblies placed in the most appropriate positions.
  • the elevator system further comprises other components such as landing and car doors, a speed limiter, a take-up of the limiter, shock absorbers for the elevator car and the counterweight; control devices of the elevator car and floor, which are not illustrated in details since they can be of conventional design and are well known to the skilled of the art.
