Description

Technical Field

[0001] The following description relates to a fixing device for fixing one end of a position code strip in an elevator shaft of an elevator installation and an elevator installation. Background Art

[0002] Elevator installations for vertically transporting persons and / or goods are an integral part of modern residential and commercial buildings. Common elevator installations include one or more elevator shafts in which one or more carriages are moved between stopping positions by drive means (such as a support device drive or a linear drive).

[0003] In such elevator installations, it is known to detect the absolute position of a respective carriage by means of a position code strip installed along the movement path of the carriage in the elevator shaft and a sensor fixed to the carriage for reading the code strip. The detection of the absolute position is crucial for controlling the elevator installation.

[0004] The position code strip is here usually configured as a flat strip, on the flat side of which position markings are provided. The position code strip is fixed at its opposite ends, in particular under a prestress, at the top or in the pit of the elevator shaft. Disadvantageously, due to the vibrations of the elevator installation, the position code strip may be damaged in the fixing area, which in the worst case can lead to a tear in the position code strip and thus to a failure in the determination of the absolute position. Summary of the Invention

[0005] Based on this situation, the object of the present application is to avoid damage to the position code strip at the fixing part of the position code strip in the elevator installation.

[0006] The object is achieved by the features of the independent main claims. Advantageous embodiments are given in the dependent claims. As long as technically feasible, the teachings of the dependent claims can be combined arbitrarily with the teachings of the independent claims and the dependent claims.

[0007] Accordingly, the object is achieved in particular by a fixing device for fixing the end of a position code strip in an elevator shaft of an elevator installation, the fixing device having: a first receiving part for completely and fixedly receiving the end of the position code strip configured as a flat strip in a defined orientation; a first fixing part for fixing the fixing device in the elevator shaft; and a compensating element connecting the first receiving part and the first fixing part, wherein the compensating element has sufficient elastic deformability for compensation in a direction parallel to the plane of extension provided on the first receiving part of the flat side of the position code strip.

[0008] The advantageous aspects are described below, and further preferred improved embodiments are described below. In particular, the description of the advantages and definitions of the features is basically descriptive and preferred, rather than restrictive examples. If the description is restrictive, it will be explicitly mentioned.

[0009] If ordinal numbers ("first", "second", etc.) are used, for example, to denote components, elements, method steps or method operations, these ordinal numbers are only set for differentiation in name and do not imply a relationship or order. This particularly means that, for example, a device does not necessarily have to have a "first component" just because it has a "second component". In addition, a device can have a "first component" and a "third component", but does not necessarily have to have a "second component" compulsorily. Multiple units with the same serial number can also be provided. In addition, for example, there can be multiple "first components".

[0010] As currently understood, an elevator installation is configured, for example, to have at least one vertical and / or horizontal elevator shaft and at least one car, but can also have multiple elevator shafts and / or multiple cars.

[0011] The car is held and driven, for example, by a support device, where the drive device transmits the driving torque through the drive axial support device. In addition, the support device is preferably connected to a counterweight assigned to the car. The drive device is particularly arranged in a machine room above one or more elevator shafts or in the upper part of the elevator shaft (i.e., the so-called shaft top). The support device is particularly configured as a rope, a conveyor belt, a belt, a chain or a similar structure and bears a tensile load along its longitudinal extension direction.

[0012] Optionally, the car is held and driven by a linear drive device. The linear drive device in an elevator installation is formed, for example, by a primary part extending along the elevator shaft and a secondary part located on the car. The primary part is formed by coils arranged successively in a line, and each of these coils is assigned an inverter, which energizes the coil when the car is in the region of the corresponding coil in order to generate a magnetic field. The magnetic field thus generated causes the car to be attracted or repelled by the magnetic field according to its set travel path. The secondary part is formed by permanent magnets or electromagnets, and the permanent magnets or electromagnets interact with the magnetic field of the coils.

[0013] The elevator shaft is a continuous shaft that is located on multiple floors of a building and / or extends along multiple areas of the building and has a cross-section configured for the car to pass through. The elevator shaft of the elevator installation can extend in the vertical direction and / or the horizontal direction. In an embodiment, the elevator installation has at least one partial section in which an elevator shaft extends vertically and at least one partial section in which an elevator shaft extends horizontally in the elevator shaft, and the car can enter the horizontally extending partial section from the vertically extending partial section.

[0014] The position code strip extends strip-like along the elevator shaft and has a plurality of position markings, and the sensor can identify at which position the car is based on the position markings. That is to say, the position markings correspond one-to-one with the positions of the position code strip. The position code strip can be, for example, a metal strip or a plastic strip. The position markings can be, for example, optical markings (such as barcodes or QR (Quick Response) codes), but the position markings can also be markings that can be read magnetically, acoustically or in other ways. The optical markings can also be formed, for example, by perforations in the position code strip. The sensor for reading the position code strip is correspondingly configured as an optical sensor, a magnetic sensor, an acoustic sensor or a sensor corresponding to other forms of position markings, and is positioned relative to the position code strip such that the sensor can detect the position markings and can reliably read the position markings in order to determine the absolute position in the elevator shaft. The position code strip can also be formed by a carrier strip and position markings applied (for example, pasted) on the carrier strip, and in this case, in particular, different materials are connected to each other.

[0015] If the position code strip is configured as a flat strip, the position code strip has a flat side on which the position markings are provided, and the width of the position code strip extending in the plane of the flat side is significantly larger than the thickness perpendicular to this plane. That is to say, the position code strip extends substantially along its longitudinal direction and width direction in the plane of the flat side, and extends only in the depth direction at a thickness sufficient for the stability of the position code strip in its transverse direction. Understand the terms in the following text according to the above description: longitudinal direction (parallel to the plane of the flat side), width direction (parallel to the plane of the flat side) and depth direction (perpendicular to the plane of the flat side). At this time, the extending plane of the flat side is constituted by the longitudinal direction and the width direction. The position code strip is usually arranged to extend longitudinally along the main extending direction of the elevator shaft. Therefore, in a vertical elevator shaft (elevator section), the longitudinal direction extends vertically, while in a horizontal elevator shaft (elevator section), the longitudinal direction extends horizontally.

[0016] "Completely fixedly" is understood to mean that the position code strip is accommodated at the first accommodating part in such a way that the movement of the position code strip relative to the first accommodating part in all directions (i.e., in the longitudinal direction, width direction and depth direction) is blocked by fixation.

[0017] Since the position code strip is arranged in a defined orientation to be accommodated in the first accommodating part, the arrangement form of the position code strip arranged therein is determined by the first accommodating part. That is to say, the position code strip can be accommodated in the first accommodating part only along one orientation. Specifically, the first accommodating part guides the position code strip to extend in the corresponding spaces in the longitudinal direction, width direction and depth direction described above.

[0018] The compensating element is understood to be an element that connects the first receiving part to the first fixing part, in particular an element that connects the first receiving part to the first fixing part along a longitudinal direction preset parallel to the position code strip, wherein the compensating element allows relative movement in at least one direction due to elastic deformation. Here, if the elastic deformability is sufficient to compensate for the movement amplitude of the position code strip under the normal load conditions of the elevator equipment, while at the same time no internal stresses related to damage occur in the position code strip, then the said elastic deformability can be considered sufficient for compensation.

[0019] The solution to the problem achieved by using the fixing device described above now includes the following technical teaching, that is, the position code strip is received at the first receiving part released in the width direction by the compensating element. This is based on the recognition that due to its design as a flat strip and small thickness, the position code strip itself can compensate for the movement along the depth direction without stress and damage through elastic bending, while the movement along the width direction occurring at the connection part between the position code strip and the first receiving part cannot be compensated by the position code strip itself. By fully fixedly receiving the position code strip and due to the relatively wide extension dimension of the position code strip in the width direction, which results in a relatively high rigidity in the width direction, the uncompensated movement in the width direction leads to the occurrence of internal stresses and thus continuous damage to the position code strip. Through the elastic deformability of the compensating element, the compensating element is used to compensate for the relative movement in the width direction between the elevator shaft and the position code strip, so that no internal stresses are generated on the position code strip and damage is advantageously avoided.

[0020] As an alternative to the features of the solution described above or provided in a preferred embodiment of the solution described above, the compensating element is configured as a metal plate, and the extending plane of the metal plate is perpendicular to the extending plane of the flat side of the position code strip provided on the first receiving part. Through the metal plate, an advantageous compromise can be achieved between, in particular, fully fixing the position code strip along the longitudinal direction of the position code strip on the elevator shaft and having sufficient elasticity in the width direction. The metal plate extends straight along the longitudinal direction under pre-tension, so that the position code strip is reliably held in its preset arrangement form in the elevator shaft. In addition, the metal plate can be configured as a stainless steel plate or an aluminum plate, for example, and only undergoes very little aging even under frequently occurring loads or deformations, so that a high service life can be achieved while reducing maintenance costs.

[0021] Alternatively to the directly preceding embodiment, the compensating element is designed as a rubber body. By using a rubber body, it is also possible to achieve an advantageous compromise, in particular, between a sufficient fixation of the position code strip along the longitudinal direction of the position code strip on the elevator shaft and sufficient elasticity in the width direction. The rubber body is oriented in the longitudinal direction under a pre-tension such that the position code strip is reliably held in its predefined arrangement in the elevator shaft. The rubber material can be designed in a particularly advantageous manner in a simple way for different loads or amplitudes of movement, so that the fixing device can be adapted in a simple way to different elevator installations, for example, according to the pre-tension of the position code strip.

[0022] Alternatively to the features of the directly preceding embodiment or as set in the preferred embodiment of the directly preceding embodiment, the first receiving part is connected to a second receiving part for receiving the compensating element in a fully fixed manner. The compensating element is then held on the second receiving part and can be separated from the first receiving part, if necessary, for maintenance or for replacement. In particular, depending on the design of the compensating element and the positional relationship between the position code strip and the compensating device, the first receiving part and the second receiving part can be connected to each other or designed jointly with each other. For example, for a metal plate with an extending plane arranged on the first receiving part perpendicular to the flat side of the position code strip, the first receiving part and the second receiving part are rotated 90° relative to each other.

[0023] Alternatively to the features of the directly preceding embodiment or as set in the preferred embodiment of the directly preceding embodiment, the first fixing part is connected to a third receiving part for receiving the compensating element in a fully fixed manner. The compensating element is then held on the third receiving part and can be separated from the first fixing part, if necessary, for maintenance or for replacement. In particular, depending on the design of the compensating element and the positional relationship between the fixing point on the elevator shaft and the compensating element, the first fixing part and the third receiving part can be connected to each other or designed jointly with each other. For example, for a metal plate with an extending plane arranged on the first receiving part perpendicular to the flat side of the position code strip, the first fixing part and the third receiving part are rotated 90° relative to each other.

[0024] Alternatively to the features of the directly preceding embodiment or as set in the preferred embodiment of the directly preceding embodiment, the first receiving part and the second receiving part are integrally formed with each other and / or the first fixing part and the third receiving part are integrally formed with each other. In this case, the fixing device is sequentially composed of a first receiving element having the first fixing part and the third receiving part, the compensating element, and a second receiving element having the second receiving part and the first receiving part. Since the integral formation of the first receiving element and / or the second receiving element can eliminate additional connection structures between the first receiving part and the second receiving part and / or between the first fixing part and the third receiving part, the assembly is made simple and the force transmission is reliably achieved through the receiving elements.

[0025] As an alternative to the features of the previously described solution or provided in the preferred embodiment of the previously described solution, the first receiving portion is configured to positively fix the position code strip, in particular by means of two clamping blocks. In this case, the fixing of the position code strip on the first receiving portion can be simply established in the installed state. Such fixing is provided, for example, by fixing devices configured as bolts, which press the two clamping blocks against each other, and the position code strip is clamped between the two clamping blocks.

[0026] As an alternative to the features of the previously described solution or provided in the preferred embodiment of the previously described solution, the first receiving portion is configured to form - fit the position code strip, in particular by a fixing device passing through the position code strip. In this case, the fixing of the position code strip on the first receiving portion can be simply established in the installed state. In particular, the form - fit connection can be combined with the force - fit connection, for example, by means of clamping blocks, which have through - holes for fixing devices configured as bolts, wherein the bolts installed here pass through additional through - holes in the position code strip and are configured to press the clamping blocks and the position code strip against each other. At this time, the bolts establish both a force - fit and a form - fit simultaneously.

[0027] As an alternative to the features of the previously described solution or provided in the preferred embodiment of the previously described solution, the first receiving portion, the first fixing portion, the second receiving portion, and / or the third receiving portion has at least one threaded connection structure. In the installed state, the threaded connection can be established particularly simply and the threaded connection structure can establish a form - fit and a force - fit as described above.

[0028] As an alternative to the features of the previously described solution or provided in the preferred embodiment of the previously described solution, the first receiving portion is configured to be wound by the position code strip. By winding, it is possible to particularly reliably fix and accommodate the position code strip on the first receiving portion. In particular, such accommodation can simply and continuously adjust the pre - tension of the position code strip.

[0029] The object is further achieved by an elevator device having: at least one elevator shaft; at least one position code strip extending along the elevator shaft and configured as a flat strip; and at least one car movable along the elevator shaft, wherein the position code strip is fixed to the elevator shaft at at least one end by the fixing device described above. The advantages described above for the fixing device can be achieved in a corresponding manner by the elevator device. In particular, due to the movability of the first receiving portion relative to the first fixing portion in the width direction achieved by the compensation element, damage to the position code strip caused by the vibration of the elevator device is avoided, thereby ensuring a long service life of the position code strip and reliable absolute position identification.

[0030] In a preferred embodiment of the directly foregoing solution, it is provided that the position code strip is fixed to the elevator shaft at both ends by the fixing means described above. Thereby, the advantages of the fixing means described above can be achieved on both sides of the position code strip and thus for the entire position code strip.

[0031] As an alternative to the features of the directly foregoing solution or as provided in a preferred embodiment of the directly foregoing solution, the position code strip has at least one notch at at least one end for passing through at least one fixing device of the position code strip, and the fixing device is used to hold the position code strip on the first receiving part. In this way, the position code strip can be held in a form-fitting and / or force-fitting connection particularly simply by the fixing device, and the connection can be established particularly simply during installation.

[0032] As an alternative to the features of the directly foregoing solution or as provided in the features of the directly foregoing preferred embodiment, the position code strip is configured as a metal strip. For a metal strip with a relatively high rigidity, failure is relatively likely to occur when internal stresses occur periodically, so the advantages of compensation are achieved to a particularly high degree.

[0040] The described embodiments are merely examples and can be modified and / or supplemented in various ways within the scope of the claims. Each feature described for a defined embodiment can be used alone or in combination with other features in any other embodiment. Each feature described for an exemplary embodiment of a particular claim category can also be used in an exemplary embodiment of another claim category in a corresponding manner.

[0041] Figure 1 The elevator installation 1 is shown, which has an elevator shaft 2 and a car 3 that is movable in the elevator shaft 2 in the vertical direction V. The elevator shaft 2 has a shaft pit 2.1 and a shaft top 2.2 and extends below a machine room 4. The car 3 is guided in the elevator shaft 2 in guide rails (not shown in detail) and is held on a support device 5, which is guided by a deflecting device 6 and a drive device 7 and is furthermore connected to a counterweight 8.

[0042] Furthermore, a position code strip 9 is provided in the elevator shaft 2 along the movement path of the car 3. The position code strip 9 has position markings 9.1, which are only schematically shown in the drawing, on its flat side 9.2 facing the car 3 over its entire length. Here, the position markings 9.1 are each configured as QR codes. The position markings 9.1 are each different from one another and each have a unique identification feature, such that the position in the elevator shaft 2 can be identified based on the respective position marking 9.1. Furthermore, a sensor assembly 10 is fixed to the car 3. The sensor assembly 10 is only shown exemplarily on the car top of the car 3. By reading the respective position marking 9.1 and its unique identification, the corresponding sensors of the sensor assembly 10 identify the absolute position of the position marking 9.1 in the elevator shaft 2 and thereby the absolute position of the car 3 in the elevator shaft 2. The position code strip 9 is held in the elevator shaft 2 by a fixing device 11, which is described in detail below.

[0043] Figure 2 A fixing device 11.1 according to the prior art is shown. As with all fixing devices 11.1 described below, the fixing device 11.1 is described in a coordinate system composed of the longitudinal direction L, the width direction B, and the depth direction T of the position code strip 9. The fixing device 11.1 is mainly formed by a fixing plate 12. The position code strip 9 is wound around the fixing plate 12 at a connecting plate 12.1 and is folded over itself and adhered to the fixing plate 12, and is held here in a completely fixed manner by a cable connector 12.2.

[0044] Figure 3A perspective view of the fixing device 11.2 according to the present disclosure is shown. The fixing device 11.2 has a first receiving portion 13 on a first receiving element 15.1 and a first fixing portion 14 on a second receiving element 15.2. The position code strip 9 is held in the first receiving portion 13 between two clamping blocks 13.1, 13.2, and the clamping blocks 13.1, 13.2 are clamped against each other in the depth direction T by a threaded connection structure provided beside the position code strip 9. That is to say, the clamping blocks 13.1, 13.2 clamp the position code strip 9 on the flat side 9.2, and the flat side 9.2 extends in the width direction B and the longitudinal direction L in the plane in which it extends. The first fixing portion 14 has a first fixing side 14.1, and the first fixing portion 14 is fixed (specifically, screwed) to a component 16 of the elevator shaft 2 by means of the first fixing side 14.1.

[0045] The compensating element 20 configured as a metal plate is held between the first receiving element 15.1 and the second receiving element 15.2, specifically, between the second receiving portion 17 and the third receiving portion 18. The compensating element 20 mainly extends in the longitudinal direction L and the depth direction T and has only a small thickness in the width direction B. Since the compensating element 20 is bendable in the width direction B, the first receiving element 15.1 and the second receiving element 15.2 are movable relative to each other in the width direction B by means of the compensating element 20. Therefore, the width direction B is parallel to the plane of extension (BxL) provided on the first receiving portion 13 of the flat side 9.2 of the position code strip 9. Like the first receiving portion 13, the second receiving portion 17 and the third receiving portion 18 are each formed by two opposing clamping blocks 17.1, 17.2 or 18.1, 18.2 respectively, and the clamping blocks 17.1, 17.2 or 18.1, 18.2 are clamped against each other in the width direction B by a threaded connection structure. The receiving elements 15.1, 15.2 are integrally formed by two mutually perpendicular regions for this purpose.

[0046] Figure 4a and Figure 4b The fixing device 11.2 is shown in another view. Figure 4a is the front view of the fixing device 11.2. Figure 4b is the side view of the fixing device 11.2. Here, the features of the fixing device 11.2 that have been described are not described again. In addition, Figure 4a and Figure 4b show the tensioning device 21 provided in the elevator shaft 2, and when viewed from the perspective of the fixing device 11.2, the tensioning device 21 is assigned to the elevator shaft 2. The tensioning device 21 has a tensioning element 22, and the tensioning element 22 acts on the component 16 and thus on the entire fixing device 11.2 in order to pre-tension the position code strip 9.
