Definitions

  • the invention relates to a device for driving a handrail.
  • the handrail can be part of an escalator or a moving walkway.
  • the invention also relates to an escalator or moving walk with such a device.
  • Escalators or moving walkways comprise a revolving conveyor belt for the transport of persons or objects and a supporting structure.
  • the step band is bounded on both sides by a respective balustrade along its conveying direction, which balustrade is arranged on a balustrade base.
  • a circumferentially guided handrail is arranged along its upper end.
  • the return of the handrail is usually integrated in the balustrade base or may alternatively be arranged in the supporting structure of the escalator or the moving walk.
  • a handrail driving handrail drive is arranged.
  • US 5,295,567 shows such a handrail drive an escalator
  • the handrail drive is arranged in a truss of the escalator.
  • the handrail drive comprises a drive belt guided circumferentially over two pulleys.
  • a to be driven by the handrail drive handrail is guided by means of a counter-pressure roller on this drive belt.
  • the handrail is moved or driven due to a resulting frictional engagement between the drive belt and the handrail.
  • the escalator also has a baffle mounted on the truss of the escalator, which is needed due to the high dimensions of the truss for further guidance of the handrail.
  • the object of the invention is therefore to provide a device for driving a handrail for an escalator or for a moving walkway, which allows a reduced wear of the handrail and the drive belt.
  • a device for driving a handrail of an escalator or for driving a handrail of a moving walk comprising: a deflected over a first and a second guide roller and a contact zone forming drive belt, and at least one counter-pressure guide roller, which causes back pressure guide roller that the handrail along the entire contact zone adjacent to the drive belt feasible and drivable by means of friction between the drive belt and handrail of the drive belt "wherein the device tangent to the pulleys tangential parallel to the axis of rotation of the pulleys trained first tangent plane and the at least one counter-pressure roller or one of the pulleys tangent second tangent plane have, wherein the second tangential plane is arranged parallel to the first tangential plane and the first and the second tangential plane are formed such that the deflection rollers and the at least one counter pressure guide roller is disposed between the tangent planes, characterized in that the device comprises a deflector located between the first and
  • the object is also achieved by modernizing an escalator or moving walk with such a device.
  • the pulley provided for the drive belt must not be used in addition to the deflection of the handrail, although such use of the pulley would allow a very small footprint for the components for operating the handrail and an additional propulsion for the handrail due to the increased contact surface. That is, in the case of a limited availability of space for installation of the device provided for driving the handrail, it would be obvious to dispense with as many components as possible to guide the handrail.
  • the device for driving the handrail must contain an additional deflecting element.
  • the deflector on the one hand allows the space-saving leadership of the handrail due to its arrangement between the trained by device tangent planes, although the deflector itself takes up additional space.
  • the appropriately placed deflector allows a gentle detachment of the handrail from the drive belt.
  • the deflection element is by a deflection roller is formed.
  • a deflection roller is formed.
  • Such a low-friction guidance of the handrail is made possible via such a deflecting element, which allows a correspondingly smaller dimensions of other components of the device.
  • a development of the device comprises a second deflection roller, wherein one of the deflection rollers is adjustably arranged to tension the drive belt and to press it against the handrail.
  • the drive belt can be tensioned and pressed against the adjacent handrail. In this way, slip between the handrail and the drive belt in the region of the contact zone can be prevented, which slip can lead to a less effective drive of the handrail.
  • a development of the device comprises a counter-pressure guide roller, which counter-pressure roller causes the handrail in the contact zone on the drive belt fitting feasible and driven by friction between drive belt and handrail from the drive belt or movable.
  • this counter-pressure guide roller By means of this counter-pressure guide roller, it is possible to press the handrail on the drive belt, whereby a drive movement of the drive belt is transferable to the handrail. In this way, the frictional engagement between the drive belt and the handrail along the contact zone can be maintained.
  • the device may comprise at least two back pressure guide rollers, wherein the at least two back pressure guide rollers form a roller arch.
  • Such a plurality of counter-pressure guide rollers comprehensive roll bow has the advantage of being able to press the handrail over a relatively long contact zone measured on the drive belt without a single of the counter-pressure guide rollers for the same purpose would have a large space-consuming diameter.
  • the deflection roller are designed as a toothed belt pulley and the drive belt as a toothed belt.
  • the drive belt may be a V-belt, preferably a poly-V belt, and the pulley may form a guide surface corresponding to the V-belt.
