Description

The invention relates to a method for mounting a support device in accordance with the general concept of the independent patent claim1.

The European patent application EP 0506323.8 describes a device and a method for mounting an elevator system which, unlike previous mounting methods, no longer requires special scaffolding or supporting platforms.

Err1:Expecting ',' delimiter: line 1 column 474 (char 473)

The purpose of the invention is therefore to improve the method of mounting a support device mentioned at the outset so that support devices of elevators with enclosed lifting cabins can be mounted in a simple, fault-tolerant and efficient manner during initial mounting or during maintenance.

The solution to this problem is given in accordance with the invention, according to the characteristics of the distinctive part of the independent claim 1.

Beneficial continuing training of the inventive step is defined by the patent claims dependent on claim 1.

Whereas, in the case of a lift system, the installation of a supporting structure in the lift shaft normally requires the installation of an auxiliary structure with work platforms at the required heights and subsequent removal, the method of the invention uses a single height-adjustable work platform, either formed on the lift shaft itself or part of the lift shaft. It is not necessary for the lift shaft to be fully installed. It is sufficient if the lift shaft already exists in a structural form and has at least one sub-surface or sub-structure with the cabin part-screw rolls and a type of work platform. The height-adjustable work platform is thus taken into account by means of a pre-configured aid device, for example, if the aid device is already in a structural form, as described in the EP6101080.03 manual.

The lifting cabin is temporarily attached to the auxiliary lift for the necessary assembly steps and, after the completion of the assembly, i.e. if it can be carried by the support, is disconnected from the auxiliary lift. It is advantageous to use as a supporting material load-bearing straps, which are much lighter than steel ropes, so that the auxiliary lift and its mounting station are not overly strained. In addition, the light load-bearing straps are easier to handle, so that the installation personnel can ideally be reduced to one person thanks to the method according to the invention. This is made possible by the fact that the removal of the railway track provides effective protection against derailment of the railway during the lifting of the elevator. A lifting system and supporting material assembled by this method are assembled in a short time and an assembly can be easily controlled.

The invention is described in detail below by means of examples and in relation to the schematic drawings.

The same and similar or similar components are shown in all figures with the same reference marks.

Figure 1 shows a lifting system 1.The lifting system 1 has a lift shaft 10 which in the example shown is bounded by a floor 10.1, side walls 10.2, 10.3 and a ceiling 10.4.The lift shaft 10 has a traction disc 12, a schematically illustrated auxiliary lifting device 14 and a first connection point 16 and a second connection point 18 for a belt-mounted load carrier 30.

The traction disc 12 is fixed and rotatable and can be driven in the conventional way.

In the present example, the 14th assistant lift is attached to the ceiling 10.4 of the 10th elevator shaft. The 14th assistant lift is used to support the 20th elevator cabin when installation and, if necessary, maintenance work is being carried out on the 1st elevator system, and the 20th assistant lift is not (yet) supported by the 30th support. The 14th assistant lift may be used in a rational way to facilitate the installation of other components (e.g. guide rails) of the 1st elevator system. After the installation has been completed, the 14th assistant lift may be removed, but it may also be considered to have some upper mass as a redundant support and propulsion device for emergency situations.

The elevator unit 1 also has the elevator cab 20 mentioned above. The elevator cab 20 is at least in structural form. The final completion of the elevator cab 20 can be made later. The elevator cab 20 has a floor plate or a lower structural part with a sub-surface 22 where the first cab perimeter coils 24.1 and second cab perimeter coils 24.2 are located, and a deck plate (or a top structure) which forms a kind of work platform in this example. The work platform 26 could also be formed by the floor plate of the elevator cab 20 if the existing structural form of the elevator cab 20 does not yet include seawalls.

The lifting cab 20 is attached to the auxiliary lifting device 14 and can be moved up and down in the lift shaft 10 by the lifting device.

The lifting device 1 also includes the above-mentioned support 30 and counterweight 32 and counterweight diversion device 34. The support 30 is formed by one or more load bearing straps, also designated by 30. The support or each load bearing strap 30 is long and flexible and has a first end 30.1 attached in the mounted state to the first connection point 16 and a second end 30.2 attached in the mounted state to the second connection point 18.

The load carrier 30 runs in the mounted state from the first connecting point 16 down the side wall 10.2 of the lift shaft 10, is rerouted through the cabin winding coils 24.1 and passed under the lift shaft 20, then routed through the cabin winding coils 24.2 and then up the side wall 10.3 of the lift shaft 20 to the traction disc 12. From the traction shaft 12 the load carrier runs in a loop 30.4 to the second connecting point 18. In loop 30.4 the counterweight is the counterweight 34 to which the counterweight 32 is attached.

The load carrier 30 consists essentially of one or more load belts, also designated 30. Each load carrier 30 has two belt surfaces. The formation of the connecting points 16, 18, the cabin rolls 24.1, 24.2, the traction disc 12 and the counterweight diversion 34 correspond to the number of load carrier belts and their formation.

The strap surface of the 30 load-bearing strap is preferably a structured strap surface 30.1, as shown in Figure 8, usually with grooves running transversely or along the direction of movement of the 30 load-bearing strap. The strap 30 is arranged so that its structured strap surface 30.1 is always facing and adjacent to or in contact with the respective rotating strap device, in the case of the deflector rotating devices, i.e. the cabin deflector coils 24.1, 24.2 and the friction disc 12 (and, if necessary, the counterweight deflector 34) and is easily adjustable to the respective deflector rotating device. This is provided that the 30 load-bearing strap is easily installed between two deflector rotating devices which allow the strap to be moved in a direction of rotation of 180°, as opposed to a 7 degree rotating shaft, which is easily adjustable to a controlled position.

The lifting device 1 also includes a clamping device 40 for clamping the support device 30. The clamping device 40 is provided in the area of the first and/or second connecting point 18. Figure 8 shows an example of a clamping device 16, 18 with clamping device 40 for and with two carrying beams 30.

Fig. 9 shows a part of the drive 12 designed to drive two load bearing belts 30; of these load bearing devices 30 only one is shown in Fig. 9. The drum 30.5 of the load bearing belt 30 runs from the cabin transverse coil 24.2 up to the drive 12 and then from the drive 12 as drum 30.6 to the counterweight transverse bearing devices 34.

The following details the individual steps of the assembly process. The order of some of the steps is not mandatory as described, depending on the constellation, certain assembly steps can be carried out in a different sequence or simultaneously.

First, the lifting cab 20 is brought or mounted in the lift shaft 10 and temporarily suspended from the auxiliary lifting device 14; for the subsequent steps, the lifting cab 20 is located in a lower shaft area, but not quite below, but at a height (distance A in Fig. 2) where the necessary access to the cabin winding coils 24.1, 24.2 is provided.

The load medium 30 is then brought into the lift shaft 10 and deposited on or in the area of work platform 26 of the lifting cab 20. The load medium 30 is then led around the cabin rolls 24.1, 24.2. It is also possible to first lead the load medium 30 around the cabin rolls 24.1, 24.2 and then deposit the load medium 30 on or at the lifting cab 20. The rest of the load medium 30 is then temporarily deposited at the lifting cab 20 especially with the first end 30.1 and the second end 30.2 on or within reach of the work platform 26 or from this. The installation interval is visible after the procedure described above.

The procedure described above is carried out for the entire load medium 30, i.e. for each load bearing strap.

A derailment guard 25 which prevents the 30th support from derailing when the support is unloaded is fitted to the cabin winding coil 24.1, 24.2 as shown in Fig. 6 in the example of the 24.1th support. The derailment guard 25 is preferably stationary, i.e. attached to a casing of the winding coil. It has a lateral guard 25.1 which prevents the 30th support from sliding sideways and a radial guard 25.2 which prevents the 30th support from being derailed in the radial direction.In Fig. 6 the derailment protection 25 is shown on the right side in a mounting position and on the left side the final position 25a is shown when the mounting is completed. The derailment protection is particularly easy to achieve when using bearings with longitudinally sliding surfaces, which are engaged with the winding 24.1, 24.2.

The lifting cab 20 is then moved, as shown in Fig. 3, by means of the auxiliary lift 14 to an upper shaft area, but not quite upwards, but to a height which allows the installation personnel to work on the work platform 26 of the lifting cab 20. For example, the lifting cab 20 is moved to an elevation in which its bottom is about 1050 mm below an upper accessible station (distance B in Fig. 3). The first end of the 30 supporting device 30.1 is then attached to the first connection point 16. The selected distances A and B are determined taking into account the actual design and dimensions of a lifting system.

The second end 30.2 is then fixed as shown in Figure 4, a part of the load medium 30 lying between the cabin transverse coil 24.2 and the second end 30.2 of the load medium 30 is conveniently lowered in a loop 30.3 into the lift shaft 10 - as this makes it easier to detect an unwanted twisting of the load medium - and then the second end 30.2 is led around the traction disc 12 and the load medium 30 or the load beams 30 are kept preferably at 180° between the cabin transverse coils 24.2 and the traction beam 12. The second end 30.2 of the load medium 30 can be fixed at the end of the second tube 18 or 20 instead of the second end 24.

The load-bearing equipment so mounted can be easily mounted by one person.

Now, seen from the lifting cabin 20, beyond the traction disc 12, a second loop 30.4 is lowered into the lower shaft area of the lifting shaft 10, so that the side wall 10.3 of the lifting shaft 10 is brought closer to the drum 30.6 and 30.7 (see also Fig. 9 and Fig. 10) within any mounting structures of these side walls 10. This loop 30.4 is formed between the drive drive 12 and the second 30.2 end of the load bearing device 30, as shown in Fig. 5.

The second loop 30.4 is lowered and the first loop 30.3 is naturally raised.

In particular, as explained above when mounting the 30 to the cabin roll 24.1, 24.2, a deflection guard is fitted in the area of the load shifting at the drive wheel 12. This deflection guard (not shown) prevents the 30 from derailing in the case of a failure of the 30 to the load shifting. A guiding function of the 30 is to be performed in normal operation of the lifting system 1 by the structured belt surface 30.1, which is directly in contact with the 12 to the drive wheel or a drive zone. If, for example, a slip of the 32 to the load shifting weight or the 20 to the lifting wheel is due to a slip of the 20 to the load shifting, the structured belt 30.1 may no longer be operated for a short time without interference from the 30 to the lifting system. For example, if a deflection guard is fitted directly in front of the 12 to the load shifting weight or the 12 to the load shifting weight, the structured belt 30.1 may no longer be able to be deflected without a short break. For example, if a deflection guard is fitted in front of the 12 to the load shifting weight or the 12 to the load shifting wheel, the 30 to the load shifting wheel or the 12 to the load shifting wheel, the 30 to the load shifting wheel, the 30 to the wheel.

The lifting cab 20 is now preferably left in the upper shaft area, while in the lower shaft area the counterweight diverter 34 is installed in the second loop 30.4 and the counterweight 32 is attached. Since the lifting cab 20 is in the upper shaft area, the loop 30.4 is suspended with the counterweight 32 and the counterweight diverter 34 in the lower shaft area. This mounting force is shown in Fig. 5. Preferably, in the same work step, a possible derailment guard is installed on the intermediate counterweight diverter 34.

When lowering the loop 30.4 into the lift shaft 10, a small weight may be temporarily attached to the load medium 30 to ensure that the load medium 30 hangs down far enough into the lift shaft 10.

Next, the second end 30.2 of the support 30 is attached to the second connecting point 18 in the upper shaft area and the support 30 is clamped. The connecting points 16, 18 direct a load-bearing force of the load-bearing equipment (30) into an surrounding building.

After this step, the lifting cab 20 is supported by the supporting medium 30 and can therefore be detached from the auxiliary lifting device 14.

Figure 10 shows the load bearing material formed by two load belts 30 in the area of loops 30.4 intended to accommodate the counterweight diverter 34. In Figure 10 this counterweight diverter 34 is not yet inside loops 30.4.

The new method makes the installation considerably easier, since the lifting cab 20 is itself used as a work platform, so that temporary work platforms or scaffolding are not necessary. However, the necessary safety measures must be taken, i.e. 26 rails or a crash barrier must be provided in the height-adjustable work platform area. The new method is made possible in particular by the use of 30 load bearing bars as load bearing means, which are much lighter and therefore easier to handle than steel ropes, requiring only one person to install the load bearing. A lifting system installed in this way can also be easily controlled. A load-bearing medium in the form of a load-bearing belt is light, a layout in the shaft can be easily controlled, so that, for example, a rollover of load-bearing belts can be easily detected and thus avoided.
