Description

 Method for mounting rails in an elevator installation

The invention relates to a method for mounting rails in an elevator installation.

The invention is applicable to elevator systems with at least one car, in particular a plurality of cars, which can be moved in a shaft via guide rails. At least one fixed first guide rail is fixedly arranged in a shaft and is aligned in a first, in particular vertical, direction; at least one fixed second guide rail is fixed in a second, in particular horizontal, direction. A converter arrangement is provided for converting the car from the first rail to the second rail. Such systems are basically described in WO 2015/144781 A1 as well as in German patent applications 10 2016 211 997.4 and 10 2015 218 025.5.

The exact alignment of the converter arrangement relative to the rails in the shaft, which are firmly arranged in the shaft, represents a great challenge, which must be ensured under the above-mentioned conditions. The, in particular rotatable, rails of the converter assembly must be aligned in the respective rotational position during the entire operating time exactly with the fixed rails, respectively with the rails in both a first direction and with the rails in the second direction, at an angle to the first direction. Tolerances even in the direction of one of the rails are extremely low. A loose storage of parts of the rails is therefore only to a limited extent considered. Each of the converter arrangements, of which in particular a plurality are provided per shaft, thus constitute fixed points in the rail system of the elevator installation, which represents a significantly higher complexity in the assembly of the rails compared to conventional elevator installations without essential converter arrangements.

Elevator systems of the type mentioned were previously presented only as concept studies or constructed as prototypes. The invention has for its object to provide a suitable, production-ready method for mounting rails especially for an elevator system of the type mentioned.

The object underlying the invention is achieved by a method according Anspruchl; preferred embodiments will be apparent from the dependent claims and the description. The method is provided for an elevator installation, which comprises: at least one car which can be moved in a shaft via rails; the rails comprise at least one fixed first shaft rail, which is fixedly arranged in a shaft and in one first, in particular vertical, direction is aligned; at least one fixed second shaft rail, which is fixedly arranged in a shaft, is aligned in a second, in particular horizontal, direction; at least one converter arrangement with at least one converter rail for converting the car from the first shaft rail to the second shaft rail, in particular the converter arrangement comprises a relative to the shaft during operation movable, in particular rotatable, third Umsetzerschiene and / or fixed relative to the shaft during operation fourth and / or fifth converter rail. The method according to the invention comprises the following method steps: a first rail mounting step in which first-mounted rails, namely the shaft rails or the converter rails, are mounted in the shaft, a second rail-mounting step in which second-mounted rails, namely the converter rails or the shaft rails, are mounted in the shaft.

The rail mounting step is initially provided to at least provisionally secure the rails to the wall. In particular, the rails are not exactly aligned with each other after this step, so that too large gaps and steps may be present at transitions between two adjacent rails. In a subsequent rail alignment step, the pre-assembled rails can then be precisely aligned.

In one embodiment, in the first rail mounting step, the bay rails are mounted as first mounted rails, and in the second rail mounting step, the converter rails are mounted as second mounted rails.

In another embodiment, in the second rail mounting step, the tray rails are mounted as two-mounted rails, and in the first rail mounting step, the converter rails are mounted as first mounted rails.

In one embodiment, the translator bars comprise a fourth fixed and a fifth fixed translator track, wherein the fourth translator track and the fifth translator track are oriented in different directions, in particular that the fourth stationary translator track (56) is aligned in the first direction (z) and the fifth fixed translator track (57) in the second direction (y) is aligned.

In one embodiment remains after the first rail mounting step and before the second rail mounting step between two erstmontierten rails a gap, in particular a Umsetzerlücke between two bay rails or a slot gap between two Converter rails; in the second rail mounting step, at least one second mounted rail is inserted into the gap. In particular, a Umsetzerschiene is inserted into a Umsetzerlücke or a shaft rail is used in a slot slot.

In essence, therefore, the structure of the rail system is such that initially one type of rail (shaft rails or Umsetzerschiene) is installed and aligned, and then the other type of rail. The mounting and alignment of a rail type requires rail-specific methods and instrument, which are thus once completely used for one rail type; Subsequently, the rail-specific methods and instrument are used for the other rail type.

In one embodiment, after the first rail mounting step, and in particular before the second rail mounting step, a first rail alignment step takes place in which the first mounted rails are aligned in the shaft.

In one embodiment, a second takes place after the first rail alignment step

Rail alignment step, in which the second mounted rails are aligned in the shaft.

In one embodiment, the translator tracks include a moveable third translator track and a fixed fourth and / or fixed fifth translator track. The fixed fourth and / or fifth converter rail and the movable third converter rail are held on a common support frame of the converter assembly. The common support frame makes it possible that the orientation of the Umsetzerschienen can be made prior to installation in the slot and maintained during mounting. The Umsetzerschienen a converter arrangement thus provide an aligned

Rail unit.

In one embodiment, before, in particular first or second,

Rail mounting step, in which the Umsetzerschienen are mounted in the shaft, the movable third Umsetzerschiene are aligned with the fixed fourth and / or fifth Umsetzerschiene on the support frame.

In one embodiment, the movable translator track is thereby indirectly aligned with the stationary bay rail by aligning a fixed translator track directly opposite the bay rail (56, 57). This is special possible because the movable Umsetzerschiene already with the fixed

Transfer rail is aligned.

In one embodiment, direct alignment of two rails takes place,

in particular the second-mounted rails compared to the erstmontierten rails, characterized in that a transition measure in particular step size and / or a gap between the two rails is determined and this determined transition measure is then set to a predetermined nominal size. For this purpose, in particular, no consuming

metrological equipment required; Rather, this can be done by using, in particular applying simple gauges directly to the rails in the transition area. In one embodiment, a gap between two rails is set by one of the rails, in particular a fixed rail is changed in length, until the gap is set to a desired size.

In one embodiment, the elevator installation further comprises an adjustment arrangement for adjusting the alignment of converter rails relative to the shaft. In one embodiment, the elevator installation comprises a Halteeirichtung, the

Halteeirrichtung further comprises: at least one shaft attachment for securing the

Holding device in the shaft; a holding frame for at least indirectly attaching the Umsetzerschienen to the holding device; an adjustment arrangement, which is designed so that the orientation of the holding frame relative to the shaft attachment is variable. In the context of the present invention, parallels are basically considered to be the same direction.

The invention will be explained in more detail with reference to FIGS. Each show

FIG. 1 shows parts of an elevator installation 50 according to the invention. The elevator installation 50 comprises fixed first shaft rails 56, along which a car 51 can be guided on the basis of a backpack storage. The first shaft rails 56 are vertically aligned in a first direction z and allow the car 51 to be moved between different floors. Parallel to one another, arrangements of such first shaft rails 56 are arranged in two parallel shafts 52 ', 52 "along which the car 51 can be guided in the first direction z by means of a backpack storage. Carriages 51 in one shaft 52 'can move largely independently and unhindered by cars 51 in the other shaft 52 "on the respective first shaft rails 56.

The elevator installation 50 further comprises fixed second shaft rails 57, along which the car 51 can be guided on the basis of the backpack storage. The second shaft rails 57 are aligned horizontally in a second direction y and allow the car 51 to be moved within a floor. Furthermore, the second shaft rails 57 connect the first shaft rails 56 of the two shafts 52 ', 52 "to one another. Thus, the second tray rails 57 also serve to transfer the elevator car 51 between the two shafts 52 ', 52 ", e.g. to carry out a modern paternoster operation.

Via a converter arrangement 53 with converter rails 58, 59, 60, the car 51 can be transferred between the first shaft rails 56 and the second shaft rails 57. The converter rails include third converter rails 58 that are movable during operation. In this example, the third converter rails are rotatably movable with respect to a rotation axis A, which is in particular perpendicular to a yz plane, which is spanned by the first and the second guide rails 56, 57. The converter rails further comprise fixed fourth and fixed fifth converter rails 59, 60. The fixed ones Although converter rails 59, 60 and the stationary shaft rails 56, 57 are movable for the purpose of alignment during the construction of the elevator system; In operation, however, the fixed rails 56, 57, 59, 60 are permanently fixed, wherein between the fixed Umsetzerschienen 59, 60 and the adjacent stationary shaft rails 57, 58 each have a transition 55 is formed. In the course of the alignment of the rails, 55 gaps SP and step dimensions ST are set to a maximum value at the transition.

All rails 56, 57, 58, 59, 60 are at least indirectly attached to at least one shaft wall of the shaft 52. The shaft wall defines a fixed reference system of the shaft. The term "shaft wall" is to be understood broadly and also comprises, as an alternative to a shaft wall formed from stone or concrete, a stationary frame structure of the shaft which carries the guide rails. The rotatable third guide rails 58 are mounted on a not explicitly designated rotary platform. The rotary platform is or the rotatable rails 58 are rotatably supported by means of a platform pivot bearing 4 (see Figures 4c and 6c).

Such systems are basically described in WO 2015/144781 A1 as well as in German patent applications 10 2016 211 997.4 and 10 2015 218 025.5. The 10 2016 205 794.4 describes in this context in detail an arrangement with integrated platform pivot and a drive unit for rotating the rotating platform, which can also be used in the context of the present invention for storage and as a rotary drive for the rotatable third rails.

Figure 2 shows one of the rails 56-60. Each rail has a defined rail axis S. The rail axis S represents an auxiliary object of the rail, by means of which the relative orientation of two rails to be aligned can be quantified. If the rail axis of the two rails are collinear, ie congruent, then the two rails are aligned with each other. If the rail axis Sl, S2 of two rails is not collinear, then a step dimension ST greater than zero is present at the transition 55 between the two rails (FIG. 2b). A lead role will then overcome an appreciable level when crossing the transition between the rails. However, the relative alignment of two rail axes to each other says nothing about the gap SP of a gap between the two rails.

A first embodiment of the method according to the invention will be described with reference to FIGS. 3 and 4. In a first rail mounting step, the first and second fixed shaft rails 56, 57 mounted in the shaft (Figure 3 and Figure 4a). On the basis of current alignment aids, the first and second shaft rails are aligned sufficiently precisely with respect to one another in a first rail alignment step, so that the rail axes S1 of initially mounted adjacent first chess rails 56 of a shaft are aligned collinear with one another. The term "collinear" also encompasses a given one

Tolerance deviation. The same applies to the second shaft rails 57, without the

Rail axes are referred to in the figures. After the first rail mounting step and the first rail alignment step remains in the region of a shaft crossing a

Translator gap 54 between two adjacent first shaft rails 56 and two

adjacent second shaft rails 57th

In the subsequent second rail mounting step Umsetzerschienen 58,59,60 are inserted into the Umsetzerlücke 54 and temporarily secured (Figure 4b). In particular, the converter rails 58, 59, 60 are already correctly aligned with one another within the converter arrangement 53 before this second rail mounting step. However, the translator bars 58, 59, 60 are not yet aligned with the chute rails 56, 57 after this step so that the rail axes S1 of the first mounted stationary chute rails 56, 57 and the rail axes S2 of the second mounted stationary translator bars 59, 60 are not collinear with each other , In addition, there is a gap SP at the transition between the Umsetzerschienen 59, 60 and the shaft rails 56, 57, which is above a predetermined limit. A guide role would currently roll over the transition from the Umsetzerschiene on the shaft rail over a too large gap, even if the rail axes Sl, S2 are aligned collinear to each other.

Through suitable adjustment means, in a second rail alignment step, the second mounted fixed rails 58, 59 are aligned with the first mounted rails 56, 57. As shown only in FIG. 4c, the second-mounted rails, namely the rotatable third converter rail 58 and the fixed fourth and fifth converter rails 59, 60 are fastened together to a flange frame 2. The Flalterahmen 2 is omitted in the remaining illustrations of Figure 4 for reasons of clarity. The orientation of the Flalterahmens 2 can be changed via adjustment with respect to a shaft attachment and thus with respect to the shaft and adjusted it. The change in the position of the Umsetzerschienen is highlighted in Figure 4b by arrows PI. A suitable adjustment possibility of Flälahmens with a Umsetzerschiene is described in detail in International Patent Application PCT / EP2018 / 050265. Figure 4c shows the state in which the rail axes Sl, S2 are aligned with each other, but the rails are still not completely aligned with each other. The step dimensions ST are now set to a predetermined maximum dimension. However, there still remains a gap with comparatively large gap SP at the transition 55. In order to set the gap SP to a predetermined maximum dimension, at least one of the fixed rails is adjusted in their length. In this example, the length of the fixed shaft rails 56, 57 is increased so that the gap SP is set to a predetermined maximum value. The change in the length of the shaft rails is highlighted in Figure 4c by arrows P2. In the same way, alternatively, the fixed Umsetzerschienen 59, 60 are changed in length accordingly. One possibility for changing the length of a rail is described in WO 2016/113434 A2. Now, the second mounted rails 58,

59, 60 fully aligned with the first mounted rails 56, 57.

FIG. 4d shows a detail of the completely aligned rail system in the area of a converter arrangement 53.

A second embodiment of the method according to the invention will be described with reference to FIGS. 5 and 6. In a first rail mounting step, the fourth and fifth fixed converter rails 59, 60 are mounted in the shaft together with the rotatable converter rail 58 (Figure 5 and Figure 6a). Based on the possibility described in PCT / EP2018 / 050265, in a first rail alignment step, the converter rails 59, 60 of the different converter arrangements 53 are aligned sufficiently precisely with respect to one another so that the first rail axes Sl of adjacent fourth converter rails 59 of a shaft are aligned co-linearly with one another. The same applies to the fifth converter rails

60, without the rail axes are designated. There remains between the shaft intersections a slot gap 64 between two adjacent Umsetzeranordnungen 53rd

In the subsequent second rail mounting step, the first and second shaft rails 56, 57 are inserted into the slot rail gap 64 and provisionally secured (Figure 6b). However, the shaft rails 56, 57 after this step are not yet aligned with the transfer rails 58, 59, 60, so that the rail axes Sl of the first mounted fixed Umsetzerschienen 59, 60 rails and the rail axes S2 of the second mounted fixed shaft rails 56, 57 not collinear are aligned. In addition, there is a gap SP at the transition between the Umsetzerschienen 59, 60 and the shaft rails 56, 57, which is above a predetermined limit. A Guide roller would currently roll over the transition from the Umsetzerschiene on the shaft rail over a too large gap, even if the rail axes Sl, S2 are aligned with each other, so in particular are collinear.

By means of suitable adjusting means, in a second rail alignment step, the second-mounted shaft rails 56, 57 are aligned with respect to the first-mounted converter rails 59, 60. As shown only in Figure 6c, the first mounted rails, a converter assembly 53, namely the rotatable third converter rail 58 and the fixed fourth and fifth converter rails 59, 60, are fastened together to a holding frame 2. The support frame 2 is omitted in the other illustrations of Figure 6 for reasons of clarity. The change in the position of the shaft rails 56, 57 is highlighted in Figure 6b by arrows P3. The adjustability of the shaft rails 56, 57 is possible as in conventional elevator systems, in particular by the use of retaining plates with slots.

Figure 6c shows the state in which the rail axes Sl, S2 are aligned with each other, but the rails are still not completely aligned with each other. The step dimensions ST are now set to a predetermined maximum dimension. However, there still remains a gap with comparatively large gap SP at the transition 55. To set the gap SP to a predetermined maximum size, at least one of the fixed rails is set in the length thereof. In this example, the length of the fixed shaft rails 56, 57 is increased so that the gap SP is set to a predetermined maximum value. The change in the length of the shaft rails is highlighted in Figure 6c by arrows P4. In the same way, alternatively, the fixed Umsetzerschienen 59, 60 are changed in length accordingly. One possibility for changing the length of a rail is described in WO 2016/113434 A2. Now the second mounted rails 56, 57 are fully aligned with the first mounted rails 58, 59, 60.

FIG. 4d now shows the detail of the completely aligned rail system in the area of a converter arrangement 53.

For reasons of clarity, the illustration of the rails 57 has been omitted in FIG.

For the alignment of the second mounted rails, so both for the adjustment of the gap dimension as well as for the adjustment of the step dimension ST, no complex technical measuring device (laser plummet, etc.) is more necessary if the erstmontierten rails already aligned correctly in the slot. The alignment can be done locally using gauges that are applied to the respective reference edges of the rails. The adjustment means is then adjusted only by trial and error until the maximum values are reached.
