Description

The invention relates to a method for installing a lift in an elevator shaft, as well as a device for installing a lift in an elevator shaft.

Elevators are often installed in elevator shafts of buildings. To optimally use the space of a building, a hoistway should be as small as possible, and an elevator should make fullest use of the hoistway. Therefore elevator shafts are tightly dimensioned, so that an optimal utilization of a building can be realized.

It may happen that a lift shaft is dimensioned such that a lift provided for it finds no room in it, or only finds place if it is arranged very precisely at a certain point in the elevator shaft. Therefore, an elevator shaft is often measured before installing a lift, so that an installer can be sure that the elevator can actually be installed. If it is determined during the measurement that the elevator shaft is too small, the elevator shaft can be adjusted if necessary, for example by tipping off shaft walls.

This measurement of the elevator shaft is conventionally accomplished with Lotschnüren. Here are mounted on a shaft ceiling at measured points suspensions, so that the leashes hang at designated positions in the shaft space. This However, the process takes a long time because the installer must make measurements, drilling and installation both in the shaft head and the shaft bottom.

In WO 2009/073010 For example, a method and apparatus for surveying elevator shafts is described. In this case, a platform is moved in the longitudinal direction of the elevator shaft, and distance sensors measure distances between this platform and the shaft walls. The platform is moved by a drive, and light sensors can be used to check a position of the platform. On the one hand, this solution provides more accurate data on the dimensions of the elevator shaft and eliminates the need to attach braids to the shaft ceiling. However, there is the disadvantage here that a drive and guide system for the platform must be installed. In addition, this solution is expensive and expensive to manufacture.

It is therefore an object of the present invention to provide a method for installing a lift in a hoistway, which is simple and quick to carry out, and which allows a sufficiently accurate check of the hoistway dimensions. In addition, installation points should be easily determined by the method.

A method according to the invention for achieving this object relates to a method for installing an elevator in an elevator shaft with the following steps: i) arranging a document in the elevator shaft, so that the arranged template images nominal dimensions of a plan of the elevator; ii) placing at least one light source at a nominal position of the original so that the light source is in shows an intended direction of travel of the elevator; iii) projecting a light beam from the light source, the light beam defining the nominal position along the intended direction of travel in the elevator shaft; and iv) using information of at least one layer of at least one projection point of the light beam in the elevator shaft for the installation of the elevator.

According to a preferred embodiment, the nominal dimensions correspond to a nominal depth and a nominal width of the elevator, so that it can be checked whether the elevator shaft provides sufficient space for the intended elevator.

According to a further preferred embodiment, the nominal position corresponds to an installation point. This makes it possible to easily determine installation points on the shaft bottom and / or on the shaft ceiling.

According to a further preferred embodiment, the light beam is used to align guide rails and / or shaft doors and / or a drive in the elevator shaft.

Another object of the present invention is to provide a device for installing an elevator in an elevator shaft, which does not have the above-mentioned disadvantages. The device should allow the implementation of the inventive method, and inexpensive to manufacture and easy to use.

An apparatus according to the invention for achieving this object relates to a device for installing an elevator in an elevator shaft, wherein the device comprises a template with a frame and means for spatial alignment of the frame. The template is suitable for mapping nominal dimensions of a floor plan of the elevator. A light source is provided for generating a light beam, template and light source being designed such that the light source can be arranged on the frame in a predefined manner, so that the light beam can be emitted in the direction of an intended direction of travel of the elevator.

FIG. 1 shows an elevator shaft 1 with a template 10 arranged therein with a light source 16 arranged thereon in a spatial representation. The elevator shaft 1 has a shaft bottom 2, a shaft ceiling 3 and shaft walls 4. The elevator shaft 1 has a shaft height 8 and a shaft depth 6 and a shaft width 7. The in FIG. 1 Lift shaft 1 shown is cuboid. The shaft bottom 2 and the shaft ceiling 3 have the same dimensions. In an alternative embodiment, the shaft bottom 2 and the shaft ceiling 3 do not have the same dimensions. It goes without saying for the person skilled in the art that elevator shafts 1 can be used with any number of storeys or manhole accesses (not shown).

In the illustrated embodiment, the template 10 is arranged on the shaft bottom. In an alternative embodiment (not shown), the template 10 is arranged at any height above the shaft bottom. The light source 16 sends a light beam 17 through the elevator shaft 1. If the template 10 is correspondingly spatially is aligned, formed on the shaft ceiling 3 of the elevator shaft 1, a projection point 21, which corresponds to a position of the light source 16 on the template 10.

The light source 16 can be moved on the original 10 along the arrows 22, which indicate a displacement movement of the light source 16. By such a displacement 22 of the light source 16 on the template 10, the projection point 21 is moved to the shaft ceiling 3, wherein the projection point 21 performs the same displacement movement as the light source 16. The arrows 23 a displacement movement of the projection point 21 is shown, which corresponds to a displacement movement 22 of the light source 16.

Since the original 10 shows nominal dimensions of a floor plan of an elevator, it can be checked in this way whether these nominal dimensions of the elevator on the entire height of the elevator shaft 1 find sufficient space. If the light source 16 is moved along the template 10, the projection point 21 should impinge on the shaft ceiling 3 at all times. If the light beam 17 is prevented from reaching the shaft ceiling 3 by a shaft wall 4, then the nominal dimension of the elevator will not be available over the entire height of the elevator shaft 1. If so, an attempt can be made to reposition the template 10. If no arrangement of the original 10 in the elevator shaft 1 can be found, in which the light beam 17 always reaches the shaft ceiling 3, then the nominal dimension of the elevator is not available on the entire height of the elevator shaft 1.

In the in Fig. 1 illustrated embodiment, correspond to a first side length of the rectangular template 10 of a nominal depth 24 of the elevator and a second side length of the rectangular template 10 of a nominal width 25 of the elevator. In an alternative embodiment, the original 10 is not rectangular, but circular, so that a hoistway can be checked for the nominal dimensions of an elevator having a circular layout.

For determining nominal positions, the original 10 with receiving elements 20 for receiving the light source 16, as shown in FIG Fig. 6 are shown to be configured.

FIG. 2 shows a template 10 in a spatial representation. The original 10 has a template broadside 11 and a document depth page 12. The template 10 is rectangular. In each case, two oppositely arranged original broad sides 11 and two oppositely arranged document depth sides 12 form the sides of a rectangle. Both template broad pages 11 as well as original pages 12 have a rectangular cross-section. On an upper side of the original broadside 11 and original page 12 a guide 13 is arranged. This guide 13 extends along the template broad sides 11 and the document depths 12, so that the guide 13 also has a rectangular shape.

In FIG. 3 a part of the template 10 and means for spatial alignment of the template 10 is shown in a spatial representation. A template broadside 11 and a document depth page 12 form a corner of the template 10. Again, the template 10, the guide 13 on her Top up. At a bottom of the template 10, a stand 15 is arranged. This stand 15 has a thread, so that it is height-adjustable connected to the template 10. On a laterally aligned surface of the template 10, a barrier 14 is arranged. Similar to the stand 15 and the lock 14 is adjustably connected to the template 10. In the illustrated embodiment, the lock 14 also has a thread.

On the template 10, a plurality of feet 15 and locks 14 may be arranged. The feet 15 allow a spatial orientation of the template 10 when it is placed on the shaft bottom. The barriers 14 allow spatial alignment of the template 10 when placed over the shaft bottom. Thus, the template 10 can be arranged at any height above the shaft floor in the elevator shaft and spatially aligned.

FIG. 4 shows a light source 16 and a portion of the template 10 in a spatial representation. The light source 16 is slidably disposed on the template 10. In the illustrated embodiment, the light source 16 along the guide 13 of the template 10 is displaceable. It is thereby achieved that a light beam 17 emitted by the light source 16 is displaced in parallel when the light source 16 is displaced.

FIG. 5 shows a guide 13 of the template 10 and a guide member 18 of the light source 16 in cross-sectional view. As in Fig. 4 illustrated, the light source 16 along the guide 13 is displaceable. According to the in Fig. 5 illustrated embodiment, engages the guide member 18, which is connected to the light source 16 is, in the guide 13 of the template 10 a. The guide element 18 and the guide 13 are dimensioned such that the light source 16 can be displaced essentially only in the intended direction, namely along the guide 13. The guide element 18 may be designed, for example, kiel-shaped or bolt-shaped.

In an alternative embodiment, the original 10 has a guiding element, and the light source 16 has a guide. It will be apparent to those skilled in the art that the guidance of the light source 16 along the template 10 can be made in a variety of ways. For example, the light source 16 may also contain guiding elements which grip around the template 10. It is important that the light source 16 can be moved on a predetermined line along the template 10.

The light source 16 is preferably guided on the original 10 such that a spatial orientation of the light source 16 and thus a direction of the emitted light beam from the light source 17, with a displacement of the light source 16 on the original 10 is always the same. The light source 16 is therefore preferably displaced parallel to its beam direction on the original 10.

FIG. 6 shows a template 10 with receiving elements 20 for receiving a light source 16 in plan view. In this representation, in turn, the guide 13 is visible, which is located on the top of the template 10. On the template 10, a support structure 19 is arranged. In turn, receiving elements 20 for receiving the light source are arranged on this support structure 19. As in Fig. 6 shown, these receiving elements 20 for receiving the light source may be formed as a half-open container with a rectangular cross-section. In this embodiment, a light source from above into the receiving elements 20 for receiving the light source can be inserted.

The receiving elements 20 for receiving the light source are arranged on the support structure 19 such that an inserted light source occupies a nominal position. As a nominal position, for example, an installation point of a guide rail can be selected, or a spatial position of a guide rail.

The receiving elements 20 for receiving the light source can be configured such that a light source fits into the receiving element 20 only in a predetermined orientation. This can for example be achieved in that the light source has a trapezoidal cross-section, and the receiving element 20 has a corresponding trapezoidal cross-section which is slightly larger than the cross section of the light source. In an alternative embodiment, the receiving elements 20 for receiving the light source are not formed as a container, but as a bolt on which a light source can be plugged with a corresponding indentation.

As in Fig. 6 shown, a plurality of support structures 19 and a plurality of attached receiving elements 20 for receiving the light source 16 may be arranged on a template 10. The number and position of the receiving elements 20 depends on the number and position of the required installation points or alignment points.

• Bei der ersten Option wird gemäss Schritt S8 die Vorlage aus dem Schacht entfernt, und das Verfahren zur Installation des Aufzuges im Aufzugsschacht ist damit beendet. In der zweiten Option gemäss Schritt S5 werden nun Installationspunkte festgelegt. Dies kann beispielsweise mittels Mitteln zur Aufnahme der Lichtquelle, wie in Fig. 6 dargestellt, ausgeführt werden. Die Installationspunkte können dabei sowohl an der Schachtdecke als auch am Schachtboden eingezeichnet werden. Sind die Installationspunkte fertig festgelegt, stehen gemäss Schritt S6 zwei Optionen zur Auswahl:
  • In der ersten Option gemäss Schritt S8 wird die Vorlage aus dem Schacht entfernt, und das Verfahren zur Installation des Aufzuges im Aufzugsschacht ist abgeschlossen. In der zweiten Option gemäss Schritt S7 werden nun Führungsschienen oder andere Aufzugsbestandteile ausgerichtet. Dazu wird die Lichtquelle an die gewünschte Nennposition der Vorlage gebracht. Die Führungsschienen, Schachttüren oder andere Aufzugsbestandteile können nun anhand des Lichtstrahls im Schacht ausgerichtet werden. Sind alle Führungsschienen, Schachttüren oder andere Aufzugsbestandteile ausgerichtet, wird die Vorlage gemäss Schritt S8 aus dem Schacht entfernt und das Verfahren zur Installation des Aufzuges in einem Aufzugsschacht ist abgeschlossen.

FIG. 7 shows a flowchart of a method for installing a lift in a hoistway. In a first step S1, the original is arranged in the elevator shaft. In a second step S2, the manhole dimensions are checked. In this check of the manhole dimensions, for example, it can be checked whether a nominal depth of the elevator and a nominal width of the elevator (as in FIG Fig. 1 shown) are available on the entire height of the elevator shaft. If the pit dimensions are negative, the original must be re-positioned in the elevator shaft. If necessary, the shaft must also be adapted in a further step S3, for example, in which material is removed from a shaft wall. On the other hand, if the check of the pit dimensions is positive, two options are available in step S4:

• In the first option, according to step S8, the original is removed from the shaft, and the process for installing the elevator in the elevator shaft is thus completed. In the second option according to step S5 installation points are now set. This may, for example, by means for receiving the light source, as in Fig. 6 shown, executed. The installation points can be drawn both on the shaft ceiling and on the shaft floor. Once the installation points have been determined, there are two options available in step S6:
  • In the first option according to step S8, the original is removed from the shaft and the process for installing the elevator in the elevator shaft is completed. In the second option according to step S7 now guide rails or other elevator components aligned. For this purpose, the light source is brought to the desired nominal position of the template. The guide rails, landing doors or other elevator components can now be aligned with the light beam in the shaft. If all guide rails, landing doors or other elevator components are aligned, the template is removed from the shaft according to step S8 and the procedure for installing the elevator in a lift shaft is completed.

The light source shown in the illustrated embodiments is preferably a laser. In this case, several lasers can be arranged simultaneously on a template 10, or only one laser, which is moved accordingly on the template 10. Alternatively, lasers can be used, which can align themselves with the help of a built-in spirit level, so that the light beam is directed vertically in the height.

The template 10 may be configured as an aluminum profile. As in Fig. 2 illustrated, the template 10 may be integrally formed. In an alternative embodiment, the template 10 consists of several components. Preferably, the original pages consist of two parts which are slidable into one another. This has the advantage that a nominal width or a nominal depth of the original 10 can be changed, so that one and the same original 10 can be used for different elevator types. The template 10 may be configured such that the displaceable template page components engage at intended positions.
