Definitions
- the present invention relates to an elevator installation with a tensioning device.
- belt-like support means which have tension members and a jacket arranged around the tension members used.
- Such belt-like support means are, similar to conventional steel cables to
- belt-like support means are less well guided laterally than conventional steel cables on the pulleys or traction sheaves.
- belt-like support means laterally offset from pulleys or traction sheaves or slip off.
- Such lateral derailment of the belt-like support means are particularly favored by diagonal pull, by fluctuating stresses in the belt-like suspension means as well as by contamination or particles, which pass between the belt-like support means and a traction sheave or pulley.
- raised side edges are used on the pulleys.
- the device should be cost-effective and robust both in production and in use.
- This object is achieved by an elevator installation in which a belt-like suspension element is guided over a traction sheave of a drive and two deflection rollers of a cabin, wherein the belt-like suspension element between the two deflection rollers of the cabin is additionally guided via a tensioning element, through which the belt-like suspension element with a Force is applied.
- the clamping element is arranged to be movable, so that the belt-like support means is displaced when the tension is released from the clamping element and thereby tightened.
- Such an arrangement of a clamping element has the advantage that thereby the belt-like support means is tensioned between the pulleys, when the tension in the belt-like support means decreases momentarily. Such a brief release of the tension in the belt-type suspension element can occur, for example, when the car is stopped as necessary. By maintaining a certain tension in the belt-like support means prevents the support means loosely rests on the pulley and can easily move laterally.
- the arrangement proposed here also has the advantage that it can be retrofitted in a simple manner in already existing elevator systems.
- the clamping element is arranged substantially centrally between the two deflection rollers of the car.
- Such a central arrangement of the clamping element between the two pulleys of the car has the advantage that thereby by only one clamping element correct guidance of the belt-like
- Supporting means can be ensured on both pulleys of the cabin.
- the belt-like support means is acted upon by the clamping element with a force acting substantially perpendicular to a longitudinal direction of the belt-like support means force.
- the clamping element acts with a clamping force in a direction away from the cabin on the belt-like support means.
- the tensioning element acts on the belt-type suspension element with a tension force in a direction towards the cabin.
- an effective direction of the clamping force of the clamping element in one direction or in the other direction can be advantageous.
- one or the other arrangement may be advantageous.
- a clamping force of the clamping element is generated by a spring. This has the advantage that it can be provided in a cost effective and reliable way, a clamping force on the belt-like suspension means.
- the clamping element comprises a shaft.
- a shaft can be formed, for example, as a rotatably mounted element, so that wear on the belt-like support means and also on the clamping element are minimized.
- the clamping element is guided in a guide, so that a movement of the clamping element takes place in a direction predetermined by the guide.
- a roller is arranged on the shaft of the clamping element. This has the advantage that thereby the belt-like support means can be unrolled low-friction over the clamping element.
- the cabin of the belt-like support means underschlept, the two pulleys of the cabin are arranged below the cabin.
- the car is suspended from the two pulleys of the car, the two pulleys of the car being located above the car.
- one or the other arrangement of the belt-type suspension element on the cabin can be advantageous.
- the belt-like support means has a contoured side, in particular a traction side with longitudinal, V-shaped ribs. This has the advantage that thereby a traction of the belt-like support means can be improved on the traction sheave, and that by the
- At least two belt-like support means are arranged in the elevator system, wherein each belt-like support means is acted upon with a separate clamping element.
- at least two belt-like suspension elements are likewise arranged in the elevator installation, wherein the belt-like suspension elements are subjected to a common tensioning element.
- one or the other variant may be preferred.
- Clamping device is basically used in many different types of elevator systems.
- Figure 1 is a schematic representation of an exemplary elevator installation according to the prior art
- Figure 2 is a schematic representation of an exemplary cabin with an exemplary clamping element
- Figure 3 is a schematic representation of an exemplary cabin and an exemplary clamping element
- Figure 4 is a schematic representation of an exemplary clamping element
- Figure 5 is a schematic representation of an exemplary guide
- Figure 6 is a schematic representation of an exemplary belt-like
- the elevator installation 1 comprises a car 2, a counterweight 3, a drive 4 and a belt-like suspension element 5.
- the belt-like suspension element 5 is fixed by a first suspension element fastening 7 in the elevator installation 1, guided via a counterweight deflection roller 10, via a traction sheave of the drive 4 guided, guided over two cabin deflection rollers 8 and secured by a second support means attachment 7 turn in the elevator system 1.
- the elevator installation 1 is arranged in a shaft 6.
- the elevator installation is not arranged in a shaft but, for example, on an outer wall of a building.
- the exemplary elevator installation 1 in FIG. 1 comprises a counterweight 3.
- the elevator installation does not comprise one
- Lift system possible. 2 shows an exemplary embodiment of a car 2 with a
- Clamping element 9 shown.
- the cabin 2 is suspended from the belt-like suspension element 5 at the cabin deflection grooves 8.
- the KabinenumlenkroUen 8 are located above the car 2.
- the clamping element 9 comprises a roller 14 and a spring 11. In this embodiment, the clamping element 9 acts on the belt-like
- Supporting means 5 with a clamping force in the direction of the cabin 2. This has the advantage that thereby takes place by the clamping element 9 no additional counterbending of the belt-like support means 5. Counterbends considerably shorten the life of a belt-type suspension element. The arrangement shown, such additional wear of the belt-like support means 5 can be prevented.
- Figure 3 is an exemplary embodiment of a car 2 with a
- Clamping element 9 shown.
- the belt-type suspension element 5 extends below the cabin 2.
- the belt-type suspension element 5 extends below the cabin 2.
- the tensioning element 9 in turn comprises a roller 14 and a spring 11.
- the tensioning element acts on the belt-like suspension element in a direction away from the car 2.
- the tensioning element 9 shown here comprises a shaft 12 and two rollers 14 arranged thereon.
- the rollers 14 have flanged wheels 17 for lateral guidance of the wheels
- the clamping element 9 is equipped with springs 11. In each case, a spring 11 is disposed at one end of the shaft 12. As a result of such an arrangement, one of the two suspension elements running in parallel can be tensioned more strongly than the other one as required.
- elements of the clamping element 9 may be rotatably mounted.
- the rollers 14 may be rotatably mounted on the shaft 12, or the entire shaft 12 may in turn be rotatably mounted.
- By running along the rollers 14 and the shaft 12 with the moving belt-like support means can be an excessive Wear of these components can be prevented.
- FIG. 5 shows an exemplary embodiment of a guide 13.
- the shaft 12 of the clamping element 9 is guided in the guide 13. Thereby, a direction in which the shaft 12 at decreasing tension of the belt-like
- FIG. 6 shows an exemplary embodiment of a belt-type suspension element 5.
- the belt-like support means 5 has a plurality of mutually parallel tension members 15 which are embedded in a common jacket 16.
- the exemplary belt-like support means 5 has a contoured side, wherein on this contoured side longitudinal V-shaped ribs are formed.
