Definitions

  • the invention relates to a method for mounting a suspension means according to the preamble of independent claim 1.
  • the object of the invention is therefore to improve the aforementioned method for mounting a support means, such that support means of elevator systems with underschlitchen elevator cars during the first assembly or in connection with maintenance work in a simple, fault-tolerant and efficient manner can be mounted.
  • a single height-adjustable working platform is used, which is formed on the elevator car itself, or the part of Elevator car is. It is not necessary that the elevator car is already complete is mounted. It is sufficient if the elevator car is present in structural form and has at least one lower surface or a lower structural part with the cabin deflection rollers and a kind of working platform.
  • the height adjustment of the work platform thus formed is preferably carried out by means of a Hilfshebezeuges that is effective in the elevator shaft.
  • Such an auxiliary hoist may already be present in the shaft, if in a previous step, the guide rails were mounted by a method, as for example in the parallel application EP05106323.8 is described.
  • the elevator car is temporarily coupled to the auxiliary hoist for the required assembly steps and disconnected from the auxiliary hoist after completion of the assembly, that is, when it can be carried by the support means.
  • a support means support straps are advantageously used, which are much lighter than steel cables, so that the auxiliary hoist and its mounting location are not stressed too much.
  • the lightweight straps are easier to handle, so that the assembly personnel can be reduced thanks to the inventive method in the ideal case to only one person. This is possible because the derailment protection effectively prevents derailment of the belt during hoisting of the elevator car.
  • An elevator system and suspension means mounted by means of this method are mounted in a short time and an assembly can be easily controlled.
  • the elevator installation 1 has an elevator shaft 10, which in the example shown is delimited by a floor 10.1 side walls 10.2, 10.3 and a ceiling 10.4.
  • a traction sheave 12 In the elevator shaft 10, a traction sheave 12, a schematically illustrated auxiliary hoist 14 and a first attachment point 16 and a second attachment point 18 for a belt-shaped support means 30 are provided.
  • the traction sheave 12 is fixed and rotatably mounted and is drivable in a conventional manner. It is preferably, as a blowing zone, integrated directly into a shaft of a drive unit.
  • the auxiliary hoist 14 is attached in the present example to the ceiling 10.4 of the elevator shaft 10.
  • the auxiliary hoist 14 is used to carry an elevator car 20 when assembly and, if necessary, maintenance work on the elevator installation 1 are carried out and in this case the elevator car 20 is not (yet) carried by the suspension element 30.
  • the auxiliary hoist 14 can optionally be used in a rational manner previously to facilitate the assembly of other components (for example, of guide rails) of the elevator system 1. After completion of the assembly, the auxiliary hoist 14 can be removed, but it can also, as a redundant support and drive means for emergencies, be left in the elevator shaft 10.
  • auxiliary hoist 14 is preferably in the highest shaft area attached flaschenzugieri device used. It would also be possible to use a fluid lifting device arranged in the lowest shaft area (eg a hydraulic system) or else a construction crane.
  • the elevator installation 1 furthermore has the already mentioned elevator cage 20.
  • the elevator car 20 is present at least in structural form. The final completion of the elevator car 20 can be done later.
  • the elevator car 20 has a bottom plate or a lower structural part with a lower surface 22 on which first cabin deflection pulleys 24.1 and second cabin deflection pulleys 24.2 are arranged, as well as a cover plate (or an upper structural part) which in the present example forms a kind of working platform 26 ,
  • the work platform 26 could also be formed by the bottom plate of the elevator car 20, in the event that the existing structural shape of the elevator car 20 does not yet include side walls.
  • the elevator car 20 can be coupled to the auxiliary hoist 14 and by this in the elevator shaft 10 up and down slidably. In Fig. 1, the elevator car 20 is shown in an upper shaft area.
  • the elevator installation 1 further includes the above-mentioned support means 30, a counterweight 32 and counterweight deflection means 34.
  • the support means 30 is formed by one or more support belts, which are also designated 30.
  • the support means or each carrying strap 30 is elongated and flexible and has a first end 30. 1, which in the mounted state at the first connection point 16 is attached, and a second end 30.2, which is mounted in the assembled state at the second attachment point
  • the support means 30 runs in the mounted state of the first connection point 16 along the side wall 10.2 of the elevator shaft 10, is deflected by the cabin deflection rollers 24.1 and passed under the elevator car 20, subsequently deflected again by the cabin deflection rollers 24.2 and along the side wall 10.3 the elevator shaft 20 up to the traction sheave 12 out. From the traction sheave 12, the support means runs in a loop 30.4 to the second attachment point 18. In the loop 30.4 is the counterweight deflection means 34, on which the counterweight 32 is mounted.
  • the support means 30 consists essentially of one or more support straps, which are also designated 30. Each strap 30 has two belt surfaces.
  • the formation of the connection points 16, 18, the cabin deflection pulleys 24.1, 24.2, the traction sheave 12 and the counterweight deflection means 34 correspond to the number of straps and their training.
  • one belt surface of the carrying straps 30 is preferably a structured belt surface 30. 1, usually with grooves running transversely or longitudinally to the direction of movement of the carrying belt 30.
  • the support belt 30 is arranged so that its structured belt surface 30.1 in the deflection-rotation devices, ie in the cabin pulleys 24.1, 24.2 and at thekultur stresssscale 12 (and, if necessary, the counterweight deflection means 34) always faces the respective deflection-rotation device and is applied to it or is in engagement therewith.
  • the carrying strap 30 is twisted by 180 ° about its longitudinal central axis between two deflection rotary devices, which rotate in opposite directions of rotation when the carrying strap 30 moves, as shown in FIG.
  • Such a belt is easy to install because it is lightweight and the structured belt surface 30.1 allows easy control of belt alignment.
  • the elevator installation 1 further comprises a tensioning device 40 for tensioning the suspension element 30.
  • the tensioning device 40 is provided in the region of the first attachment point and / or the second attachment point 18. 8 shows an example of a connection point 16, 18 with a tensioning device 40 for and with two carrying straps 30.
  • the tensioning takes place by means of a screw device (for example by means of a threaded rod and counter nut).
  • Fig. 9 shows a part of the traction sheave 12, which is designed for driving two carrying strap 30. Of these support means 30 is shown in Fig. 9 only one.
  • the strand 30.5 of the support belt 30 extends from the cabin deflection pulley 24.2 up to the traction sheave 12 and then from the traction sheave 12 as a strand 30.6 to the counterweight deflection means 34. From Fig. 9 it can be seen that the structured belt surface 30.1 is engaged with the traction sheave 12 is.
  • the elevator car 20 is brought into the elevator shaft 10 or mounted there and temporarily suspended on the auxiliary hoist 14.
  • the elevator car 20 is located for the subsequent process steps in a lower shaft area, but not at the bottom, but at an altitude (distance A in Fig. 2), in which one has the necessary access to the cabin pulleys 24.1, 24.2.
  • the support means 30 is brought into the elevator shaft 10 and deposited on the work platform 26 of the elevator car 20 or in its area. Then, the support means 30 is guided around the cabin deflection rollers 24.1, 24.2. It is also possible first to guide the suspension elements 30 about the cabin deflection pulleys 24. 1, 24. 2 and then deposit the suspension element 30 on or on the elevator cage 20. Provisionally, then the remaining part of the support means 30, in particular with the first end 30.1 and the second end 30.2 on or on the working platform 26 or from this reachable from the elevator car 20 deposited.
  • the assembly intermediate state after carrying out the method steps described so far is shown in FIG. 2.
  • a derailment protection 25 which prevents derailment of the suspension element 30 in the case of suspension elements, is installed in the cabin deflection roller 24.1, 24.2 as shown in FIG. 6 using the example of the cabin deflection roller 24.1.
  • the derailment protection 25 is advantageously stationary, that is, attached to a housing of the deflection roller. It has a lateral guide 25.1, which prevents a lateral slippage of the support means 30 and it has a radial guide 25.2, which prevents a suspension medium loose in the radial direction. Unthreaded is inevitable during the installation of the suspension element 30, since the suspension element (not yet) is tensioned.
  • suspension medium loose can also result during operation if, for example, when the elevator car 20 ascends to the usually present final buffer, a short-term relief of suspension elements 30 takes place.
  • the derailment protection 25 is shown on the right side in a mounting position and on the left side, the end position 25a can be seen when the assembly is completed.
  • the derailment protection is particularly easy to implement when support means are used with longitudinally grooved surface, which are in engagement with the guide roller 24.1, 24.2.
  • the derailment protection in this case only prevents a suspension element loose in the radial direction. As a result, a lateral displacement is prevented, since the longitudinal grooves of the belt, which are engaged with corresponding counter-grooves of the guide pulley prevent this.
  • the elevator car 20 is brought as shown in FIG. 3 by means of the auxiliary hoist 14 in an upper shaft area, but not quite upwards, but in an altitude that allows the assembly personnel to be active on the working platform 26 of the elevator car 20.
  • the elevator car 20 is in this case, for example, brought to an altitude in which its bottom is about 1050 mm below an uppermost approachable station (distance B in Fig. 3).
  • the first end 30.1 of the support means 30 is attached to the first attachment point 16.
  • a definition of the mentioned distances A, B is carried out taking into account the actual design and dimensions of an elevator installation 1.
  • the statements made in connection with the present patent application are examples of a concrete embodiment.
  • the second end is held 30.2, a part of the support means 30, which lies between the cabin deflection roller 24.2 and the second end 30.2 of the support means 30 is advantageously lowered in a loop 30.3 in the elevator shaft 10 - since at This procedure makes it easier to detect an unwanted twisting of the suspension element - and then the second end 30.2 is guided around the traction sheave 12.
  • the support means 30 and the carrying strap 30 are preferably twisted selectively between the cabin deflection pulleys 24. 2 and the traction sheave 12 by 180 °.
  • the second end 30. 2 of the suspension element 30 can be provisionally fixed to the second connection point 18 or to the cabin 20.
  • the support means so mounted can be easily mounted by a person.
  • a second loop 30.4 is lowered into the lower shaft area of the elevator shaft 10, in such a way that its side wall 10.3 of the elevator shaft 10 is closer to 30.6 and 30.7 (see also FIG. 9 and Fig. 10) is guided within any mounting structures of this side wall 10.
  • This loop 30.4 is formed between the traction sheave 12 and the second end 30.2 of the suspension element 30, as shown in FIG.
  • Mounting structures of the side wall 10 are, for example, brackets, which are guided around the counterweight 32 to allow attachment of a cabin guide.
  • this derailment as shown by the example of the cabin pulleys 24.1 in Fig. 6, mounted stationary is.
  • the traction sheave 12, or a pulley can be designed with small dimensions if such a derailment is used.
  • a traction sheave may then be integrated directly into a shaft or roller, for example, without protruding shoulders.
  • the elevator car 20 is now preferably left in the upper shaft area, while in the lower shaft area the counterweight deflection means 34 is installed in the second loop 30.4 and the counterweight 32 is attached. Since the elevator car 20 is located in the upper shaft area, the loop 30.4 hangs with the counterweight 32 and the counterweight deflection means 34 in the lower shaft area.
  • This assembly intermediate state is shown in FIG. 5.
  • a possible derailment is attached to the counterweight deflection means 34.
  • connection points 16, 18 introduce a carrying capacity of the support means (30) into a surrounding building.
  • the connection point 16, 18 is for example attached to a wall of the elevator shaft or they are arranged on guide rails or they are connected to structures of a drive.
  • FIG. 10 shows the support means formed by two carrying straps 30 in the region of the loops 30.4, which are intended to receive the counterweight deflection means 34.
  • this counterweight deflection means 34 is not yet within the loops 30.4. It is introduced prior to attachment to the counterweight 32, see Fig. 10, in the loops 30.4.
  • the new method substantially simplifies assembly because the elevator car 20 itself is used as a work platform so that temporary work platforms or scaffolds to be temporarily installed are not necessary.
  • the necessary safety measures must be taken, which means that it is necessary to provide railings or fall protection devices in the area of the height-adjustable working platform.
  • the new method is made possible, in particular, by using support straps 30 as carrying straps which are much lighter and therefore easier to handle than Steel cables, whereby only one person is needed to mount the carrying straps.
  • Such a mounted elevator system can be easily controlled in the following.
  • a support means in the form of a support belt is easy, an arrangement in the shaft can be easily controlled, so that, for example, a rollover of shoulder straps easily detected and thus can be avoided. This allows the entire installation of the elevator installation in a short time and without complex auxiliary structures in the elevator shaft or in the building.
