Description

Arrangement of guide rails

The invention relates to an arrangement of guide rails for an elevator installation with at least one car which can be moved along the guide rails, with at least one first guide rail and at least two second guide rails, wherein the respective longitudinal sides of the first and second guide rails are each arranged in a plane which enclose an angle (a) with each other.

The invention is applicable to elevator installations and in particular to those elevator installations in which comparatively high forces are transmitted to the shaft wall via the guide rails.

Conventional guide rails used in elevator construction have a so-called "T" profile, in which the rail head provided with the guideways is formed integrally with the rail foot, the rail head being arranged in the middle of the rail foot so that the cross section of the rail head and rail foot is " T "results. Such a guide rail is attached to both sides of the rail head on the rail. An example of an arrangement with such guide rails is shown in FIG. There, the forces acting on the guide rails are also indicated in the form of arrows. In elevator systems in which comparatively high forces act on the guide rails, elastic deformations occur both on the rail foot and in the rail head, so that an accurate and comfortable passenger guidance of a car is no longer guaranteed. In the previously used "T" profile rails, the elastic deformation is further enhanced by the taper between the guideways arranged on the rail head and the rail foot taper, and in elevator systems using a linear motor for driving the elevator car, the guide is sufficiently rigid required to maintain the required tolerance for the engine air gap.

On this basis, the invention has the object to provide an improved arrangement of guide rails for an elevator system, which allows accurate and rigid guidance of the car and a linear drive.

To solve this problem, an arrangement of guide rails for an elevator installation according to claim 1 is proposed, as well as an elevator installation with such an arrangement of guide rails according to claim 14. Advantageous Embodiments emerge from the subclaims and from the following description.

The arrangement of guide rails according to the invention for an elevator installation has at least one car, which can be moved along the guide rails. The arrangement of guide rails has at least one first guide rail, which has a substantially rectangular cross section with two longitudinal sides and two broad sides. The arrangement of guide rails further comprises at least two second guide rails, which have a substantially rectangular cross-section with two longitudinal sides and two broad sides, and are arranged with respect to their longitudinal extent and with respect to the broad sides of their cross-sections parallel to each other. The respective longitudinal sides of the cross sections of the at least one first and the at least two second guide rails are each arranged in a plane which enclose an angle (a) with each other.

It is proposed that on a first broad side of the cross section of the at least one first guide rail, a first bearing for the positive bearing of the first broadside in both directions along the broad side is provided, and that at a first broad side of the cross section, each of the at least two second guide rails a second Bearings for positive storage of the first broadside in both directions along the broad side is provided.

In the context of this invention, a substantially rectangular cross-section is understood to mean a cross-section which essentially has two longitudinal and broad sides running parallel to one another, wherein one longitudinal side and one broad side are arranged substantially perpendicular to one another. Chamfers, fillets, offset or curved versions of one or more sides should also be covered by the definition of "substantially rectangular cross-section", as long as a four-sided basic shape is recognizable as the underlying Even if it does not result directly from the cross section itself, but because of its positioning in the proposed arrangement, which side is to be understood as a longitudinal or broadside.

The respective longitudinal sides of the cross sections of the at least one first and the at least two second guide rails are each arranged in a plane, which enclose an angle (a) with each other. In the proposed arrangement, the raceways or guide surfaces for the guide rollers are arranged on the longitudinal sides of the respective first and second guide rails. These lie in a plane whose one direction is defined by the longitudinal extension of the guide rails, and whose other direction results from the arrangement of the cross section of the first and second guide rails to each other. The respective planes thus include an angle (a), which is 0 ° in a parallel arrangement of the guide rails and 90 ° in a mutually perpendicular arrangement. Characterized in that between the guide rails and thus between the arranged thereon guideways, in particular a larger angle than α = 0 ° is arranged, forces acting in different directions can be transmitted from the car to the guide rails and absorbed by them. The angle (a) can have any appropriate value. In this case, mutually inclined rails are conceivable, which are arranged for example at an angle of 45 ° in particular to the zy plane, the rails to each other an angle α of 90 ° but also an angle α of 45 ° or may include another angle.

As a bearing, which serves for the positive storage of a guide rail, a device is understood, which rests in particular directly on the guide rail mounted by the bearing. Such a bearing absorbs forces which are transmitted over a surface or edge or line on the guide rail from the guide rail to the bearing. As a result, the guide rail is mounted on the respective bearing surface, d. H. supported against the acting on the bearing surface, absorbed by the bearing force. In the present case, a bearing is used in particular for deriving the forces resulting from the driving operation of the car from the guide rail.

By arranging a form-fitting mounting on the first broad sides of the cross section of the guide rails, which supports this first broad side in each case in both directions along the broad side, in particular a higher rigidity of an arrangement of guide rails is achieved. In the proposed manner, elastic deformations of the guide rails are reduced and a more accurate and stiffer guidance of a car and linear drive is achieved. In one embodiment of the arrangement of guide rails, the arrangement has at least two first guide rails, which are arranged with respect to their longitudinal extension and with respect to the longitudinal sides of their cross-section parallel to each other. In an arrangement of, for example, at least two instead of only one first guide rail, the forces absorbed by the first guide rails can be divided into two guide rails.

In one embodiment of the arrangement of guide rails, at least one of the two longitudinal sides of the cross section of the at least one first guide rail and / or the at least two second guide rails at a distance from the first broad side, a third bearing for the form-locking storage of the longitudinal side in the corresponding direction of the broadside intended. Such a third bearing, which is provided at a distance from the first broad side, reduces elastic deformation of the substantially rectangular profile of the guide rail. In an advantageous embodiment, the distance of the third bearing from the first broad side is designed so that it is as close as possible to the distance of the track of the traveling on the first guide rail guide roller from the first broad side. If a guide rail has only one longitudinal side of a track or guide surface for a guide roller, the distance of the third bearing of the first broad side ideally corresponds to the distance of the track of the guide roller, which moves on the guide rail. The third bearing is arranged on the longitudinal side of the guide rail, which lies opposite the track of the guide roller.

In the same way can be provided on both longitudinal sides of the cross section of a guide rail at a distance from the first broad side third bearing for positive storage of the longitudinal side in both directions of the broad side. Opposedly disposed third bearings provided at a distance from the first broad side reduce elastic deformation of the substantially rectangular profile of the guide rail in both directions along the longitudinal sides of the cross section. In an advantageous embodiment, the distance between two oppositely disposed third bearing of the first broad side is designed so that this is as close as possible to the distance of the track of the traveling on the second guide rail guide rollers. At the respective longitudinal sides of the cross section of a guide rail opposite third bearing are provided in particular when moved to the guide rail oppositely arranged guide rollers. Generally, the smaller the distance of a third bearing from the track of the guide roller, the lower the elastic deformation of the bearing guide rail.

In one embodiment of the arrangement of guide rails, at least one bearing is formed on a bearing element. If the bearings described above are formed on individual bearing elements, then they can be arranged freely along the guide rails and thus flexibly connectable in particular to the shaft wall or a carrier structure. The respective extent of a bearing element in the longitudinal direction of the guide rails is flexibly selectable. For example, a bearing element may extend substantially over the entire length of a guide rail in its longitudinal direction. Short interruptions, especially for constructive reasons are of course also possible with such a design. A substantially over the entire length extending bearing element is particularly advantageous when high forces acting on the guide rail, which are to be absorbed by the bearing element in order to prevent an elastic deformation of the guide rail in particular continuously.

In a further embodiment of the arrangement of guide rails, a plurality of bearing elements are arranged along the longitudinal extent of a guide rail. In this way, a flexible mounting of the guide rail is possible. In this case, bearing elements extending to different lengths over the length of the guide rail can also be used, for example, depending on the respective load of a guide rail in different areas. In addition to the respective longitudinal extension of a bearing element and the embodiment, for example, with respect to the distance of a third bearing from the first broad side can be varied in particular, the distance between the individual bearing elements.

In one embodiment of the arrangement of guide rails according to at least one of the preceding embodiments, at least one bearing or a bearing element is connected to the shaft wall, and in particular arranged on a support structure connected to the shaft wall. The execution of a bearing element and its integration in a supporting structure or attachment to the shaft wall is flexibly adaptable in the proposed arrangement. In one embodiment of the arrangement of guide rails, the form-fitting mounting is provided in the form of a form-fitting receptacle, in particular arranged on a bearing element, or in the form of a form-fittingly arranged fastening element. In a form-fitting trained recording is usually a arranged in a fitting recess or groove, which is adapted to the dimensions of the first broad side of a guide rail and has sufficient depth to provide a positive reception, without that in a particular lateral load the guide rail, the risk of tilting or the like. Such a recess can of course also be made in several parts in the context of the invention, for example, from at least two components which are held together by means of a screw and which form a positive receptacle between them.

A positive storage can also be provided in the form of a form-fitting arranged fastener. Such a fastening element may for example be a projection surrounding the guide rail, in which the guide rail is received in a form-fitting manner. Likewise, an additional form-fitting arranged fastener may be provided, for example in the form of a screw or riveting to produce a positive storage, wherein the forces to be dissipated via one or more arranged on such a fastener mold surface (s) are added.

In one embodiment, the arrangement of guide rails, a non-positive storage is provided in addition to the positive storage. Such additional frictional bearing can be advantageous if the storage should be suitable for receiving high forces. By means of a non-positive bearing, for example, a bias can be provided, which allows the inclusion of larger forces by the storage.

In one embodiment of the arrangement of guide rails, the planes in which the respective longitudinal sides of the cross sections of the at least one first and the at least two second guide rails are arranged enclose an angle (a) which in one embodiment is for example between 45 ° and 135 ° and in particular 90 °. At an angle of 90 °, the respective longitudinal sides of the at least two first and the at least one second guide rails are at right angles to each other arranged. The arrangement of these levels results in the direction of the transmitted from the car on the guide rails force components which act on the guide rail on the storage. Assuming that the same forces are transmitted horizontally from the car to the guide rails in all directions, the arrangement of the guide rails at an angle of α = 90 ° divides the absorption of the forces approximately equally on the guide rails. Even with an arrangement in a larger angular range such as 45 ° to 135 °, a largely uniform distribution of forces on the guide rails can also be achieved depending on the structure.

In one embodiment of the arrangement of guide rails, this has an axis of symmetry, which is arranged parallel to the longitudinal direction of the guide rails, and with respect to which the cross sections of the at least one first and / or the at least two second guide rails are arranged symmetrically. A symmetrical structure of the arrangement and thus a symmetrical absorption of forces that are transmitted from the car to the guide rails, reduces the risk of possible twisting and elastic deformation of the assembly due to uneven power transmission and thus supports in addition an accurate and rigid guidance of the car.

In one embodiment of the arrangement of guide rails, the cross section of a guide rail on the first broad side has a greater extent than the cross section of a guide rail on the second broad side, d. H. the cross section of the guide rail increases towards the first broad side. Such a configuration of the cross section of a guide rail can be advantageous, for example, if, for structural reasons, no third bearing can be arranged in order nevertheless to provide a sufficiently rigid design of the guide rail. However, if a third bearing can be arranged only at an unfavorable distance from the track of the guide roller, a design may be expedient, in particular for high-acting forces, in which the cross section of a guide rail on the first broad side has a greater extent than on the second broad side.

In one embodiment of the arrangement of guide rails, guide surfaces for guide rollers of the elevator installation are arranged on the longitudinal sides of the first and / or the second guide rails. In such an embodiment, on the long sides of the Guide rails additional material to be provided, which is to ensure that even after a reasonable period of expected wear and tear the broad side of the guide rails and thus their bending resistance torque does not fall below a required level. It is also possible to provide a different material for the guide surface, as the material of the guide rail, such as a material with better running and / or wear properties.

To solve the problem, an elevator system is further proposed, which has a trained according to the foregoing description arrangement of guide rails.

An embodiment of the elevator installation has a plurality of arrangements of guide rails:

at least one fixed first arrangement of guide rails, which is fixedly arranged in a shaft and is aligned in a first, in particular vertical, direction,

- At least one fixed second arrangement of guide rails, which is fixedly arranged in a shaft and a second, in particular horizontal, direction is aligned, and

- At least one opposite the shaft rotatable third arrangement of guide rails, which is fixed to a rotary platform and is convertible between an orientation in the first direction and an orientation in the second direction.

Such arrangements of guide rails have elevator systems, in which in particular a plurality of cars can be moved in a shaft via guide rails. At least one fixed first arrangement of guide rails is fixedly arranged in a shaft and is aligned in a first, in particular vertical direction; at least one fixed second arrangement of guide rails is fixedly aligned in a second, in particular horizontal, direction, and at least one third arrangement of guide rails rotatable relative to the shaft is fastened to the rotary platform and can be moved therewith between an orientation in the first direction and an orientation in the second direction. A car of such elevator systems is attached via a hinge to a chassis, which can be moved along the guide rails rolling guide rollers along the guide rails is. In particular, in a central suspension of the car to the chassis, there are long levers between the suspension and the guide rollers, whereby relatively high forces act on the guide rails on the guide rails. The arrangement of guide rails according to the preceding description improves the guidance of the car or the chassis in particular by an improved absorption of acting on the guide rails high forces.

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

1a shows an exemplary arrangement of guide rails with guide rails 8 known in the prior art from above, and thus transversely to the longitudinal direction of the guide rails 8. The guide rails 8 are in a vertical (z) direction over a Supporting structure 53 attached to the shaft wall 52a in the shaft 52. As can be clearly seen in Fig. 1a, two guide rails 8 are arranged perpendicular to each other to absorb the forces acting during the process of the car. In Fig. 1a, the effective direction of these forces is indicated by arrows. In each case, forces act in both directions of the x-axis on the two outer guide rails 8 and forces in only one direction of the y-axis on the two inner guide rails 8, this being only schematically the direction of the main components of the forces acting on the guide rails 8 should show. The known guide rails 8 used in the illustrated arrangement are respectively attached to both sides of the rail head on the rail. In elevator systems in which comparatively high forces act on the guide rails 8, elastic deformation occurs in these guide rails 8 both on the rail foot and in the rail head. In Fig. 1 a, the viewing direction of the schematic representation in Fig. 1 b is further drawn on the basis of a section line with arrows.

1 b schematically shows an exemplary arrangement of a car 51 of an elevator installation 1. The car 51 can be moved on an arrangement of guide rails 10, which has first 1 1 and second 12 guide rails. During the vertical process, the car 51 is guided on the basis of the guide rails 1 1, 12. In the illustration in FIG. 1 b, the arrangement of guide rails 10 is fastened to the shaft wall 52 a of the elevator shaft 52 via a supporting structure 53. On the guide rails 11, 12 roll guide rollers 21, which are fixed to a chassis 16.

Fig. 2 shows an exemplary arrangement of guide rails 10 according to the invention, which is compared to the arrangement of guide rails of Fig. 1a suitable for receiving higher forces, which are of a car 51, which is movable along the guide rails 1 1, 12 transmitted. The guide rails 11, 12 are arranged symmetrically with respect to an axis of symmetry 20. The arrangement of guide rails 10 has two spaced-apart first guide rails 1 1, which have a rectangular cross-section 30 with two longitudinal sides 31 and two broad sides 32 (shown in Fig. 3a), and two second guide rails 12, which has a rectangular cross-section 40 with two longitudinal sides 41 and two broad sides 42 (shown in Fig. 3b), and with respect to their longitudinal extent (longitudinal direction of the guide rails) and with respect to the broad sides 42 of its cross-section 40 in parallel are arranged to each other. The respective longitudinal sides 31, 41 of the cross sections 30, 40 of the first 1 1 and the second 12 guide rails are each arranged in a plane 43, 44 which enclose an angle α with each other.

2 also shows (for details, see FIGS. 3 a, 3 b) that on a first broad side 32 a of the cross section 30 of the first guide rail 11, a first bearing 35 for the positive bearing of the first broad side 32 a in both directions y along the broad side 32 a is provided, and that on a first broad side 42a of the cross section 40 of the second guide rails 12, a second bearing 45 is provided for positively supporting the first broad side 42a in both directions x along the broad side 42a.

At the two first guide rails 1 1, a third bearing 55 is arranged on one of the two longitudinal sides 31 of the cross section 30 at a distance a1 from the first broad side 32a, which is provided for positive bearing of the longitudinal side 31 in the y direction of the broad side 32. Likewise, a third bearing 55 is provided on the second guide rails 12 at a distance a2 from the first broad side 42a for positively locking the longitudinal side 41 of the second guide rail 12 in the x direction of the broad side 42.

FIG. 3 a shows an exemplary embodiment according to the invention of a first guide rail 1 1 with an exemplary bearing element 36 arranged thereon in a larger representation. As already shown in Fig. 2, but in Fig. 3a is better seen, is on the first broad side 32a of the cross section 30 of the first guide rail 1 1, a bearing element 36 with a first bearing 35 in the form of a recess for positive storage of the first broadside 32a provided in both y-directions along the broad side 32. Further, on a longitudinal side 31 of the cross section 30 of the first guide rail 11, a third bearing 55 for positive storage of the longitudinal side 31 of the first guide rail 1 1 in the y-direction relative to the running in the longitudinal direction of the guide rail track 22 of a guide roller whose acting force by an arrow 21 a is provided.

3b shows an exemplary embodiment according to the invention of a second guide rail 12 with an exemplary bearing element 46 arranged thereon in a larger representation. As already shown in FIG. 2, but can be better seen in FIG. 3 b, a bearing element 46 with a first bearing 45 for the form-fitting bearing of the first is provided on the first broad side 42 a of the cross section 40 of the second guide rail 12 Broadside 42 a provided in both x-directions along the broad side 42. Furthermore, on the first broad side 42a of the cross section 40 of the second guide rail 12, two third bearings 55 for positively supporting the longitudinal sides 41 of the second guide rail 12 in both x-directions relative to the raceways 22 of the guide rollers, which by arrows 21 b, 21 c, which indicate the direction of the acting force. The two third bearings 55 are produced by the bearing element 46 and a fitting 47 connected thereto. The screw connection is arranged at a distance a2 from the first broad side 42a of the cross section 40 of the second guide rail 12. The screw head 47a forms in this embodiment, a third bearing 55 for the positive storage of the longitudinal side 41st

FIG. 4 a shows another exemplary embodiment of a guide rail 12 according to the invention, in particular for arranging a second guide rail 12 in a groove or recess 45 of a bearing element 46, which constitutes a second bearing 45. This embodiment is used, for example, when forces 21b, 21c are transmitted to a guide rail 12 on both sides of guide rails 12 on both sides and, for reasons of space in particular, no third bearing 55 can be arranged on the longitudinal sides 41 of the guide rail 12 , The exemplary second guide rail 12 therefore has only one arranged on its first broad side 42 a second bearing 45. The substantially rectangular cross-section 40 of the second guide rail 12 is formed wider (b2) toward the first broad side 42a in order to increase the bending resistance torque of the guide rail 12 in relation to an elastic deformation of the cross-section 40. The second broad side 42b has a width b1 in the exemplary embodiment, and the first broad side 42a has a correspondingly increased width b2. The guide track 22 of the guide rollers extends at a distance d1 from the first broad side 42a.

4b shows a further exemplary embodiment according to the invention of a guide rail 12 in accordance with the framework conditions described for FIG. 4a. Compared with the bearing element 46 shown in Fig. 4a, the bearing element 46 of Fig. 4b, a first bearing 45 in the form of a recessed recess 45a with further along the longitudinal sides of the cross section 40 of the guide rail 12 extending bearing flanks 45b. The fact that the recess 45a is arranged close to a side surface of the bearing element 46, there is a risk of deflection of the bearing edge 45b, as shown in dashed lines in Fig. 4b. At the same time there is the danger of a deflection of the Guide rail 12, as also indicated by dashed lines. In order to prevent such a deflection of the bearing flank 45b, in the embodiment in FIG. 4b, in addition to the positive-locking bearing 45, a further positive and non-positive bearing 48 (the screw connection is also prestressed in addition to the positive connection) is provided in the form of a screw connection. The guideway 22 of the guide rollers 21 extends at a distance d2 from the first broad side 42a.

FIG. 5 shows a schematic representation of parts of an exemplary elevator installation 50. The elevator installation 50 comprises a fixed first arrangement of guide rails 56, along which a car 51 can be guided on the basis of a backpack storage. The fixed first array of guide rails 56 is vertically aligned in a first direction z and allows the car 51 to be moved between different floors. Arranged parallel to one another in two parallel shafts 52 ', 52 "are arrangements of such fixed first guide rails 56 along which the car 51 can be guided. <br /> <br /> Cars in the one shaft 52' can be largely independent and unhindered by cars in the other shaft 52 "on the respective first guide rails 56 move.

The elevator installation 50 further comprises a fixed second arrangement of guide rails 57, along which the car 51 can be guided. The second array of guide rails 57 is aligned horizontally in a second direction y, and allows the car 51 to be moved within a floor. Further, the second arrangement of guide rails 57 interconnect the first arrays of guide rails 56 in the two shafts 52 ', 52 "., Thus, the second arrays of guide rails 57 also serve to transfer the car 51 between the two shafts 52', 52".

Via a rotatable third arrangement of guide rails 58, the car 51 can be transferred from the first arrangement of guide rails 56 to the second arrangement of guide rails 57 and vice versa. The third guide rails 58 are rotatable with respect to a rotation axis A which is perpendicular to a y-z plane which is spanned by the first and second guide rails 56, 57.

All arrangements of guide rails 56, 57, 58 are fastened at least indirectly to at least one shaft wall 52a of the shaft 52. The shaft wall defines a fixed reference system of the shaft. The term shaft wall alternatively also includes a stationary frame structure of the shaft which carries the guide rails. The rotatable third arrangement of guide rails 58 is attached to a turntable 53.

FIG. 6 shows a three-dimensional illustration of an exemplary arrangement 10 according to the invention of two first 11 and two second 12 guide rails, which are fastened to a suspension 61 on the shaft wall 52a via a rotatable support structure 53. As shown in Fig. 2, the first guide rails 11 are held in a bearing member 36, as shown in Fig. 3a. As is apparent from Fig. 6, the guide rails 11 are secured in this bearing element 36 by means of screw 49. The second guide rails 12 are analogous to the embodiment shown in Fig. 3b by means of fittings 47, which represent second 45 and third 55 bearings, positively and additionally mounted non-positively on a bearing element 46.

The suspension 61 has at the four corners externally arranged brackets 61 a, which are fixedly connected to the shaft wall 52a. In Fig. 6, it will be readily appreciated that the support structure 53 is circular and rotatable to translate the rotatable third array of guide rails 58 between the orientation shown in Fig. 6 in the z-direction to an orientation in the y-direction , In this case, the support structure 53 can rotate both in a clockwise and counterclockwise direction about an axis of rotation arranged in the x-direction.
