Definitions

  • the field of the disclosed technology relates generally to a mounting device for shielding at least two ropes within an elevator roping arrangement.
  • connection points are attached within connection points of different parts of the elevator roping arrangement, such as the elevator car, the counterweight or dead end hitches of the elevator hoistway.
  • the connection points comprise regularly a shielding means, which ties the ropes together and therefore relative movements between the ropes are prevented.
  • a break or getting loose of a rope due to the movement or due to the rotation of the rope within the connection points cause stresses in the ropes and therefore reduces the lifetime of the ropes.
  • WO 2011/045215 A1 discloses an elevator system having a suspension and a suspension for supporting and/or moving at least one elevator car in an elevator system, wherein the suspension can be guided and driven at least by means of a sheave, in particular a traction sheave of a drive machine of an elevator system, and the suspension comprises a body made of a polymer and at least one tie beam extending in the longitudinal direction of the suspension and embedded in the body and made of wires and is present as a cord or rope.
  • US 2012/0132487 A1 discloses an elevator system that has at least one elevator car and at least one counterweight connected by a suspension device, both of which can be counter-directionally displaced at at least one guide rail in an elevator shaft via a traction sheave of a drive.
  • At least one pivotable suspension anchoring is adaptable to displacements of the suspension device according to a displacement angle wherein a rolling body moves on a holding plate.
  • US 7,086,217 B2 discloses a rope apparatus including two ropes of synthetic fiber strands arranged for taking up a force applied in a lengthwise direction.
  • the ropes are arranged a predetermined distance apart and are fixed by a rope sheathing forming a fixed link running in the lengthwise direction between the two ropes.
  • the rope apparatus also has at least one reinforcement element for the mechanical reinforcement of the rope sheathing.
  • US 2006/0016641 A1 discloses an elevator installation including an elevator car located in a hoistway and having a floor, and a rear wall extending upward from the floor.
  • a counterweight is located in the hoistway adjacent to the rear wall of the elevator car.
  • An underslung sheave assembly is located generally below the floor and preferably forms a V-shaped configuration that operatively engages the elevator car.
  • a drive machine is mounted in the upper portion of the hoistway, and a drive sheave operatively engages the drive machine and is located above the counterweight, with the drive sheave having a front edge.
  • a deflector sheave is also mounted in the upper part of the hoistway generally below the drive sheave and has a rear edge that vertically overlaps with the front edge of the drive sheave.
  • a first rope and a second rope each have a first end attached to one of a first and a second dead end hitch in the upper portion of the hoistway, with the under-slung sheave assembly operatively engaging the first and second ropes to support the elevator car and the counterweight operatively engaging the first and second ropes as the first and second ropes extend from the drive sheave to the counterweight, and with the first and second ropes extending from the underslung sheave assembly around the rear edge of the deflector sheave and the front edge of the drive sheave such that the first and second ropes wrap around the drive sheave greater than 180 degrees.
  • the present invention discloses a mounting device for shielding at least two ropes usable within an elevator roping arrangement, wherein the mounting device is connectable with the first of the at least two ropes and the other rope of the at least two ropes is freely movable within the mounting device.
  • a first component and at least another component are attachable with each other and form in combination a fixing means for the first rope and a shielding means for the at least one other rope.
  • the fixing means can be attachable with one of the at least two parallel ropes, but also other fixations of the shielding means with the rope arrangements are possible.
  • the shape of the first and of the at least further component define in combination the fixing means with a dimension close to the diameter of the first rope and an opening with a dimension greater than the diameter of the at least other rope.
  • Other dimensions of the openings and different dimensions and/or shapes for different openings of the shielding means can be used.
  • the second component of the mounting device can be the shielding means.
  • at least one element of the mounting device is attachable to a ground wall of the elevator roping arrangement and also at least two other ropes are freely movable within the opening and the first rope is fixed within the fixing means.

  • the connections 70a, 70b attach the at least two components 20, 30 to each other and are preferably a screw joint, click connections or other possible connectors of the components 20, 30.
  • the backside of the first component 20 is also attachable via the connection 70a with a hoistway wall, a ground wall or other parts of the elevator roping arrangement.
  • connections 70a, 70b can be used for attaching the first component 20 to the backside and/or with the second component 30 used as a shielding means 60 of the mounting device 10.

  • the mounting device 10 comprises one fixing means 40 for fixing the mounting device 10 to the at least one rope and the opening 50 in which at least another rope is freely movable.
  • the screw connection 70 of the mounting device 10 is removed, the mounting device 10 can easily be placed along the rope or be dismounted quickly from the rope.
  • the mounting device 10 can easily and quickly be placed, shifted or dismounted from the rope within the connections points.
  • the forms of the first component 20 and of the second component 30 of the mounting device 10 are different compared to the shapes of the first and second components 20, 30 according to Fig. 1 .
