  • the object of the invention is to overcome the above-mentioned drawbacks.
  • a specific object of the invention is to disclose an arrangement for driving a handrail belt that is as simple, cheap and reliable in construction as possible and that additionally enables a low-construction travelator, moving ramp or escalator suitable to be mounted on a fixed base without a pit formed in the fixed base.
  • the travelator, moving ramp or escalator f the invention is characterized by the features of claim 1.
  • Preferred embodiments of the invention are characterized by what is disclosed in the dependent claims. Inventive embodiments are also presented in the description part and drawings of the present application.
  • the travelator, moving ramp or escalator of the invention comprises a people mover for supporting and transporting people; a balustrade extending alongside the people mover throughout its length, said balustrade comprising a handrail belt implemented as an endless loop and having an upper handhold portion that the passenger can grasp with a hand for support, and a lower return portion; and a drive means for moving the handrail belt, said drive means comprising a drive pulley mounted with bearings at the end of the balustrade so as to be rotatable about a first axis of rotation, over which drive pulley the handrail belt is bent by about 180° between the handhold portion and the return portion, and a power means having a drive shaft rotating about a second axis of rotation to impart rotation to the drive pulley.
  • the first axis of rotation and the second axis of rotation coincide coaxially.
  • the drive pulley and the power means are coaxial.
  • the travelator, moving ramp or escalator is of a low-construction design and intended to be mounted on a fixed base, such as a floor or other support.
  • the power means is a gearless electric motor that has a flat shape in the direction of the drive shaft and can be installed in a small space.
  • the drive means comprises pressure rollers arranged to apply spring pressure to the handrail belt to press it against the drive pulley.
  • the drive means comprises a tensioning roller arranged within the return portion of the handrail belt at a point near the drive pulley to engage the handrail belt and deflect it to form a bend immediately after the drive pulley so as to tension the handrail belt.
  • the invention has the advantage that the drive arrangement of the handrail belt is simple, cheap and reliable enabling a low-construction travelator, moving ramp or escalator that is suited to be mounted on a fixed base without requiring a pit to be made in the fixed base for the drive machinery.
  • the drive pulley is mounted directly on the drive shaft of the power means.
  • the power means is a permanent-magnet synchronous motor.
  • the drive means is disposed at the exit end of the travelator, moving ramp or escalator as seen in the transport direction.
  • the drive means is disposed at the entry and exit ends of the travelator, moving ramp or escalator.
  • Fig. 1 presents a low-construction travelator designed to be mounted on a fixed base, such as a floor or other support, which means that no pit has to be made in the fixed base for the travelator machinery.
  • a fixed base such as a floor or other support
  • the travelator comprises a people mover 1, which may be e.g. a pallet conveyor or a belt conveyor, which is supported on a frame 14.
  • the frame 14 lies on a floor throughout its length.
  • the frame 14 comprises two elongated frame parts 15, 16, which are connected by a number of transverse members 17 extending transversely between the frame parts to hold them parallel to each other at a distance from each other.
  • the travelator comprises two balustrades 2, one on either side of the conveyor 1.
  • Each balustrade 2 comprises a balustrade frame 18 preferably made of glass or some other transparent material and fastened to profiled metal members serving as frame parts 15, 16.
  • the balustrade comprises a handrail belt 3 formed as an endless loop having an upper handhold portion 4, which the passenger can grasp with a hand for support, and a lower return portion 5.
  • the upper edge of the balustrade frame 18 functions as a guide bar on which the upper handhold portion 4 of the handrail belt 3 slides.
  • the lower return portion 16 has been arranged to run inside the frame part 15, 16.
  • a drive means 6 for driving the handrail belt 3 is provided at that end of the handrail belt 3 which is the exit end of the handhold portion 4 of the handrail belt and correspondingly the exit end of the conveyor 1 as seen in the transport direction.
  • the drive means may be disposed at the entry end of the balustrade or at both the entry and exit ends.
  • the drive means 6 comprises a drive pulley 7 having a relatively large diameter and mounted with bearings so as to be rotatable about a first axis 8 of rotation.
  • the handrail belt 3 is bent over the drive pulley 7 by 180° from handhold portion 4 into return portion 5.
  • the drive pulley 7 is driven by a power means 9 having a drive shaft 11 rotating about a second axis 10 of rotation, the drive pulley 7 being secured directly to the drive shaft, so that the first axis 8 of rotation and the second axis 10 or rotation coincide coaxially.
  • the power means 9 is of flat construction and takes up little space in the direction of the drive shaft 11.
  • the power means 9 is preferably an axial frequency-controlled permanent-magnet synchronous motor (e.g. standard elevator motor KONE EcoDisc ® , manufactured by Kone Corporation, Finland) which is of a flat construction and can therefore be installed in a small space.
  • KONE EcoDisc ® motor uses no oil at all, thus eliminating the risk of fire and reducing environmental risks.
  • the KONE EcoDisc ® motor has a very high efficiency: it only requires half of the energy required by corresponding traditional geared machines. The required starting current is only about 40 percent of the current required by an ordinary frequency-converter controlled motor.
  • the weight of the KONE EcoDisc ® motor is only half the weight of corresponding traditional geared machines.
  • the compact size of the motor minimizes the space required by it, thus increasing the productive useful area of the building.
  • the KONE EcoDisc ® motor has only one moving part. Being of gearless type, the motor has a longer service life than traditional geared electric motors.
  • the gearless KONE EcoDisc ® motor ensures an exceptionally smooth and quiet operation of the handrail belt.
  • the small amount of materials and only one moving part in the motor facilitate maintenance, the service life is long and fault diagnosis and preventive maintenance are made easier as compared with traditional handrail belt drives.
  • As the KONE EcoDisc ® motor is gearless, it has a very low frictional resistance.
  • the energy consumption is only about half of the energy consumption of a corresponding geared motor.
  • the oil-free motor reduces environmental risks and the risk of fire.
  • the drive means 6 comprises a number of pressure rollers 12, in Fig. 3 five rollers, which have been arranged to apply spring pressure to the handrail belt 3 to press it against the drive pulley 7 in order to achieve a sufficient frictional contact between the inner surface of the handrail belt 3 and the circumferential surface of the drive pulley 7.
  • the drive means 6 further comprises a tensioning roller 13, which is arranged within the return portion 5 of the handrail belt 3 in the immediate vicinity of the drive pulley 7 and in contact with the outer surface of the handrail belt so that the handrail belt is deflected and forms an upward bend immediately after the drive pulley 7.
  • the tensioning roller 13 ensures a sufficient tension of the handrail belt 3.
