Description

Technical area

[0001] The following statements relate to a support frame for a car carriage with a secondary part of a linear drive and for rotatable fastening to a car cabin in an elevator system. Technical background

[0002] Elevator systems for transporting people and / or goods are an integral part of modern residential and commercial buildings. A typical elevator system comprises one or more elevator shafts in which one or more elevator cars are moved between landing positions by means of drives such as suspension drives or linear drives.

[0003] Under the name "MULTI," the applicant manufactures elevator systems with linear drives, in which multiple cars can be moved completely independently of one another in one or more elevator shafts and along differently oriented travel lanes. Such systems allow, among other things, a single elevator shaft to be utilized more efficiently than a single-car system, thus reducing waiting times.

[0004] In the aforementioned elevator systems with linear drives, it is known to suspend the elevator car from a car carriage. The car carriage comprises a secondary part of the linear drive and is guided in the elevator shaft by means of rollers on at least one guide rail. A car cabin is designed to be rotatable relative to the car carriage, so that the elevator car can be moved along vertical or horizontal guide rails or primary parts of the linear drive while maintaining a consistently upright orientation.

[0005] Such car carriages are complex and delicate components with considerable weight, making them difficult to handle during assembly, transport, and subsequent maintenance. DE 10 2024 102 273.6 discloses a method in which a guide rail attachment is installed on the car carriage during assembly and used to handle the car carriage during transport and for inserting the car carriage into the elevator shaft. Such a solution requires a guide rail attachment for each car and thus incurs relatively high costs.

[0006] From WO 2019 / 129541 A1, an elevator system with an elevator shaft and a car movable in the elevator shaft is also known, which comprises a service vehicle for picking up an elevator car located in a holding floor.

[0007] Based on this situation, the present task is to simplify the handling of a car carriage during assembly, transport and / or maintenance and to reduce associated costs. Description - Technical Solution

[0008] The present object is solved by the features of the independent claim. Advantageous embodiments are specified in the subclaims, the description, and the drawings. To the extent technically feasible, the teachings of the subclaims may be combined arbitrarily with the teachings of the main and subclaims.

[0009] In particular, the object is accordingly achieved by a receiving frame for a car carriage with a secondary part of a linear drive and for fastening, in particular, in a rotatable manner to a car cabin in an elevator system, the receiving frame comprising at least one U-shaped frame with a lower base leg and two side legs extending upwards from the base leg for receiving the car carriage with its furthest extent between the side legs and with its second furthest extent perpendicular to the base leg, wherein a space enclosed by the U-shaped frame completely encloses the car carriage in any case up to the height of the side legs when the car carriage is arranged upright, and wherein at least on the side legs there is a first attachment point for fastening, in particular for fastening rotatably about a longitudinal axis of the car carriage,of the car carriage.,

[0010] Advantageous aspects are explained below, and preferred modified embodiments are described further below. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be expressly stated.

[0011] Where ordinal numbers, such as "first", "second", etc., are used, for example to designate a component, an element, a method step, or a method action, these ordinal numbers are intended purely for differentiation in the designation and do not indicate any dependencies or sequences. This means, in particular, that, for example, a device does not have to have a "first component" in order to have a "second component". A device can also have a "first component" and a "third component" without necessarily having a "second component". Multiple units of the same ordinal number can also be provided, for example, multiple "first components".

[0012] According to the present understanding, an elevator system is designed, for example, with at least one vertical and / or horizontal elevator shaft and at least one car that can be moved in the elevator shaft, but can also have several vertical and / or horizontal elevator shafts, each with at least one car.

[0013] In the elevator systems encompassed by the present disclosure, a car is formed at least by a car cabin and a car carriage and is held and driven by a linear drive. A linear drive in an elevator system is formed, for example, from a primary part extending along the elevator shaft and a secondary part located on the car, in particular on the car carriage. The primary part is then formed from coils arranged one behind the other in a line, each of which is assigned a converter. The coil is energized to generate a magnetic field when the car is located in the region of the respective coil. The magnetic field is generated such that the car is attracted or repelled by the magnetic field according to its intended travel path.The secondary part is formed, for example, by a permanent magnet or electromagnet that interacts with the magnetic fields of the coil.

[0014] An elevator shaft is a continuous shaft that extends over multiple floors and / or along multiple areas of a building and has a cross-section designed for the passage of the elevator car. An elevator shaft of the elevator system can extend in a vertical and / or horizontal direction. In one embodiment, the elevator system has at least one partial section of the elevator shaft in which the shaft extends vertically and at least one partial section in which the elevator shaft extends horizontally, wherein the elevator car can pass from the vertically extending section into the horizontally extending section. In a further embodiment, several travel lanes, for example vertical and horizontal travel lanes, are arranged in an elevator shaft.

[0015] A car carriage is particularly designed as part of a backpack frame of the elevator car, thus extending mainly on one side of the elevator car, in particular the rear side opposite the car door. The car carriage is then guided on one or more guide rails on the corresponding side of the elevator shaft, with the primary part of the linear drive also being located on this side of the elevator shaft. The car carriage has a secondary part of the linear drive and is rotatable relative to the rest of the elevator car, in particular relative to the elevator car. The car carriage can then be transferred, for example on a transfer device, between a horizontal guide rail section and a vertical guide rail section of the elevator system and rotated for this purpose. A simultaneous rotation of the car carriage relative to the rest of the elevator car or to the car car keeps the car car upright.

[0016] A support frame is used primarily for transporting the car carriage and / or supporting it during assembly and / or maintenance. It serves, for example, to protect and support the car carriage and ensure its accessibility, for example for work on it and / or for removing it from the support frame or inserting it into the support frame, for example by means of a crane.

[0017] A U-shaped frame and a cross member described below are formed, for example, by interconnected profile struts and / or profiled sheets or plates. In particular, the design of the struts, sheets and / or plates and / or their interconnection makes them rigid overall, making them suitable for the aforementioned purposes without deformation. If the frame is U-shaped, the U-shape is evident in a cross-section of the frame.

[0018] Insofar as reference is made to the extension of the car carriage, this refers to three significant extensions of the car carriage in three mutually perpendicular spatial directions. In particular, the car carriage has a shape that can be used to define corresponding extensions. For example, the car carriage is essentially cuboid-shaped.

[0019] To the extent that the U-shaped frame completely encloses the car carriage, the car carriage does not protrude beyond the frame in that area. To the extent that the side legs only extend over part of the second-widest extent, the car carriage does not protrude beyond the frame in the vertical range of the side legs; rather, the frame merely protrudes vertically beyond the side legs. An upright arrangement is understood to be an arrangement in which the second-widest extent of the car carriage is perpendicular to the base leg. As an exception to this, the car carriage can be tilted within the frame for specific purposes, as described below.

[0020] An attachment point is defined as a point on the support frame that, in a given arrangement of the car carriage, is assigned to a point on the car carriage to form a connection for securing the car carriage in the support frame. This connection is then arranged and designed in such a way that all of the car carriage's weight forces to be absorbed are absorbed across the total number of attachment points.

[0021] The solution to the problem with the above-described support frame now includes the principle that the car carriage is held in a vertical position and completely enclosed. The car carriage can then be transported safely and with relatively little space requirement, whereby the support frame protects the car carriage and can be designed cost-effectively. Furthermore, the position in which the car carriage is held on the support frame, or the positions into which a rotatably mounted car carriage can be placed on the support frame, offer good accessibility for assembly and / or maintenance. The car carriage can therefore be mounted directly in the support frame and transported therein after completion.Furthermore, the support frame can be kept on the elevator system after the car carriage has been installed in the elevator system and can later be used for the maintenance of one or more car carriages with the advantages described above.

[0022] Another advantage is that the force is absorbed in the receiving frame directly on the car carriage. A guide rail attachment known from the prior art does not have to be attached to the car frame for transport, but can, for example, be attached to the car carriage only at the elevator installation in order to transfer the car carriage from the receiving frame into the elevator shaft. For example, the guide rail attachment can be attached to or removed from the car carriage when the car carriage is arranged in the receiving frame. A single guide rail attachment can then be used for multiple cars, both during the initial installation of the elevator system and during subsequent maintenance of cars or car carriages. It is then advantageously sufficient to only have a relatively expensive guide rail attachment available, even if the elevator system has multiple cars.

[0023] The first attachment points are arranged, in particular, coaxially with a longitudinal axis, in particular at a center of gravity of the car carriage. If the car carriage is mounted so as to be rotatable about the longitudinal axis of the car carriage, the car carriage can be arranged upright in the support frame for transport and tilted for assembly and maintenance. In the tilted position, the car carriage then protrudes from the space enclosed by the support frame. The support frame can advantageously be used for maintenance in such a way that particularly good accessibility to all components of the car carriage is achieved.

[0024] Alternatively or additionally, at least a second attachment point for securing the car carriage can be provided on the base leg. Particularly for transporting the car carriage, force can then be introduced into the support frame at another point to evenly distribute the load on the support frame. Furthermore, the car carriage is additionally secured in its upright transport position in this way.

[0025] Alternatively or additionally, the side legs can extend over the entire second-longest extent of the car carriage, so that the space enclosed by the U-shaped frame completely encloses the car carriage. Such an arrangement is particularly advantageous for transporting the car carriage.

[0026] Alternatively or additionally, it can be provided that the side legs are each divided into two parts, with a first part extending between the base leg and the respective first attachment point and a second part extending between the first attachment point and an upper end of the second furthest extent of the car carriage when the car carriage is arranged upright. In particular, it can be provided that the first part and the second part can each be detachably connected to one another. Particularly advantageously, the receiving frame can then be configured with the first and second parts of the side legs in order to transport the car carriage, while the receiving frame is configured with only the first part of the side legs in order to assemble and / or maintain the car carriage with advantageously increased accessibility. The second part can, for example, also be permanently connected to the first part after assembly for transport.

[0027] Alternatively or additionally, the support frame may further comprise a cross member arranged opposite one another between the side legs and the base leg. The cross member terminates the U-shaped frame at the top, is detachably connectable to the side legs, and forms at least a third attachment point for securing the car carriage. The support frame then completely encloses the car carriage on all sides for particularly good protection, particularly during transport. By detaching the cross member, the support frame can be opened upwards, for example, to insert or remove the car carriage.

[0028] Alternatively or additionally, it can be provided that the at least one third attachment point is designed to support the entire weight of the car carriage, such that the car carriage is completely held on the cross member. The cross member can then remain attached to the car carriage for removal and insertion of the car carriage and can be moved with it. In this case, crane attachments, in particular crane eyes, can be formed in a simple and conveniently positioned manner on the cross member, while the car carriage is arranged on the cross member under defined conditions. The cross member can also have third attachment points for receiving different components, for example different car carriages, in order to be able to handle these different components in the same way during the same crane attachments.

[0029] Alternatively or additionally, it may be provided that means for rotating the car carriage are arranged at the first attachment points. The car carriage can then be rotated for assembly and / or maintenance using the rotating means to improve accessibility.

[0030] Alternatively or additionally, the support frame can be designed as a transport frame and furthermore has cover plates to enclose the space enclosed by the support frame on all sides. The car carriage is then completely covered and thus completely protected against damage and / or contamination.

[0031] Alternatively or additionally, at least one cover plate may have at least one recess for the passage of a crane attachment, in particular a crane attachment on the crossbeam. A crane attachment can then be formed directly on the support frame, so that the cover plates have no force-transmitting effect and a complex and expensive, highly rigid design of the cover plates can be dispensed with.

[0032] Alternatively or additionally, it can be provided that the receiving frame is designed as an assembly frame and further comprises an assembly receptacle arranged between the first attachment points. An assembly receptacle can be provided, for example, for arranging first components and / or certain components which, in turn, cannot be arranged at the attachment points. An assembly receptacle can be used, in particular, at the beginning or at an early stage of the assembly of the car carriage and can then remain on the receiving frame, form part of the car carriage, and / or be removed after the car carriage has been independently received at the attachment points.

[0033] Alternatively or additionally, the mounting fixture can be designed as a non-magnetic assembly table for mounting the secondary part of the linear drive to the car carriage. The secondary part can then be mounted on the assembly table without interacting with the table, allowing the pre-assembled car carriage to be placed on the secondary part and then connecting the car carriage and secondary part to each other.

[0034] Alternatively or additionally, feet and / or casters can be arranged on the base leg. This allows the support frame to be easily movable for simplified transport and / or designed for access by a forklift, for example. Short description of the drawings

[0035] A preferred technical solution is explained in more detail below with reference to the accompanying drawings using preferred embodiments. The term "figure" is abbreviated to "Fig." in the drawings.

[0036] The drawings show Fig. 1 a highly schematic view of an elevator system with linear drive; Fig. 2 is a perspective view of a receiving frame with a car carriage received therein according to the present disclosure; Fig. 3 an exploded view of a support frame according to Fig. 1; Fig. 4 a perspective view of a cross member of a receiving frame according to Fig. 1 with the car carriage attached to it; Fig. 5 a perspective view of a receiving frame according to Fig. 1 with cover plates arranged thereon; Fig. 6 a perspective view of a receiving frame according to Fig. 1 with the car carriage accommodated therein in an assembly / maintenance position; Fig. 7 is a perspective view of a receiving frame according to the present disclosure with a car carriage received therein in an assembly / maintenance position; and Fig. 8 is a perspective view of a receiving frame according to the present disclosure with a mounting receptacle arranged thereon and components of a car carriage during assembly. Detailed description of the drawings

[0037] The described embodiments are merely examples that can be modified and / or supplemented in a variety of ways within the scope of the claims. Each feature described for a specific embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a specific claim category can also be used correspondingly in an embodiment of another claim category.

[0038] Fig. 1 shows a highly simplified illustration of a lift installation 1 with a lift shaft 2, wherein the lift shaft 2 has a plurality of shaft doors 2.1, each assigned, for example, to floors of a building. In the lift shaft 2, a guide rail 3 is arranged on a wall opposite the shaft doors 2.1, which is held to the wall by means of a plurality of brackets 4. A lift car 5 is arranged on the guide rail 3 so as to be movable between the shaft doors 2.1, wherein the lift car 5 is held on a lift car frame 6. The lift car frame 6 is formed from a lift car carriage 6.1 guided on the guide rail 3 and a support part 6.2 rotatably connected to the lift car carriage 6.1. For the rotatable connection, a Fig. 4, Fig. 6, Fig. 7 and Fig. 8 shown car car holder 19. The car carriage 6.1 also has a Fig. 2 and Fig. 8 shows a secondary part 9 of a linear drive, which interacts with primary parts of the linear drive (not shown) in the elevator shaft 2 to drive the elevator car 5 and in Fig. 2 partially illustrated guide means 18 for guiding on the guide rail 3. The car carriage 6.1 can also have a schematically illustrated service brake 7, by means of which the car carriage 6.1 and thus the car cabin 5 can be fixed relative to the guide rail 3.

[0039] To insert the relatively complex and heavy elevator car carriage 6.1 with little play relative to the guide rail 3 or the primary part on the guide rail 3, a guide rail attachment 8 can be arranged, for example, at the upper end of the guide rail 3. This guide rail attachment 8 is inserted into the elevator shaft 2 together with the elevator car carriage 6.1 held thereto by the service brake 7 and is secured to the split bracket 4.1 and the attachment bracket 4.2. When inserting the guide rail attachment 8, it is positioned by the brackets 4.1, 4.2 or by the adjustment means provided thereon such that the guide rail attachment 8 is aligned with the guide rail 3, so that the carriage 6.1 can be moved onto the guide rail 3 without obstruction after the service brake 7 is released.

[0040] Fig. 2 shows a receiving frame 10 with a car carriage 6.1 accommodated therein. The receiving frame 10 serves, for example, to transport the car carriage 6.1 from a manufacturing location to a place of use, wherein, for example, at the place of use immediately before the car carriage 6.1 is introduced into the elevator shaft 2, the guide rail attachment 8 is mounted on the car carriage 6.1, while the car carriage 6.1 is still accommodated in the receiving frame 10. The receiving frame 10 has, as also shown in the Fig. 3, a U-shaped frame 10.1 with a base leg 11 designed as a frame construction and two side legs 12.1, 12.2 standing perpendicular to it, each designed as a frame construction. Furthermore, the receiving frame 10 has a cross member 13 extending between the side legs 12.1, 12.2, which is also designed as a frame construction. The components of the U-shaped frame 10.1 are, for example, permanently connected to one another, for example joined together, while the cross member 13 is designed to be detachable from the frame 10.1. First attachment points 14.1 are formed on the side legs 12.1, 12.2, to which the car carriage 6.1 is attached, in particular coaxially with its axis of rotation. Furthermore, second attachment points 14.2 are formed on the base leg 11 and third attachment points 14.3 are formed on the cross member 13, to which the car carriage 6.1 is attached to the receiving frame 10. The car carriage 6.1 is held firmly and sufficiently rigidly in the receiving frame 10 via the attachment points 14.1, 14.2, 14.3, for which purpose appropriately designed fastening points (not shown in detail) are provided on the car carriage 6.1.

[0041] The car carriage 6.1 is arranged with its furthest extent E.1, which can also be referred to as the longitudinal extent, between the side legs 12.1, 12.2, with the second furthest extent E.2, which can also be referred to as the transverse extent, in the Fig. 2 shown configuration perpendicular to the base leg 11 in a vertical direction V. A shortest extension E.3 of the car carriage 6.1, which can also be referred to as depth extension, lies in a depth direction T of the receiving frame 10. The car carriage 6.1 is therefore in the configuration of Fig. 2, which is provided in particular for transporting the car carriage 6.1, on one short side and thus extends essentially in an upright plane, wherein the car carriage 6.1 lies, in particular in the depth direction T, completely within the space enclosed by the U-shaped frame 10.1; the receiving frame 10 thus encloses the car carriage 6.1.

[0042] Furthermore, the base leg 11 has feet 15, so that the base leg 11 is sufficiently spaced from a subsurface (not shown in detail) to allow a forklift to grip underneath the base leg 11. Alternatively, but not shown, heavy-duty rollers for moving the receiving frame 10 can be arranged on the base leg 11. The cross member 13 also has crane attachments 16, by which the cross member 13, in particular with the car carriage 6.1 attached thereto, or the entire receiving frame 10, in particular with the car carriage 6.1 accommodated therein, can be lifted. Fig. Figure 4, for example, shows a crossbeam 13 held by a crane 17, to which the car carriage 6.1 is held. The third attachment points 14.3 and corresponding fastening points of the car carriage 6.1 are then designed such that the entire weight of the car carriage 6.1 can be carried thereon. The car carriage 6.1 can be lifted by means of a crane 17, as shown in Fig. 4, can be inserted into and / or lifted out of the receiving frame 10, wherein the cross member 13 is connected to the side legs 12.1, 12.2 or detached from the side legs 12.1, 12.2.

[0043] Fig. 5 further shows a transport configuration of the receiving frame 10, wherein it is covered on all sides by cover plates 20 with the car carriage 6.1 accommodated therein. The car carriage 6.1 is then completely enclosed by the cover plates 20, with the upper cover plate 20 having recesses 20.1 for the crane handles 16 to pass through, so that the crane handles 16 protrude upwards out of the housing through the recesses 20.1. The cover plates 20 and the receiving frame 10 protect the car carriage 6.1 during transport and allow it to be easily handled, for example, by means of a crane 17 or a forklift.

[0044] Fig. Figure 6 shows a maintenance and / or installation configuration of the support frame 10, wherein the car carriage 6.1 is only supported at the first attachment points 14.1 on the two side legs 12.1, 12.2. The attachment points 14.1 are located in a rotation axis of the car carriage 6.1, allowing it to rotate for easy access to all components of the car carriage 6.1.

[0045] Fig. 7 shows a Fig. 6 shows a configuration of the support frame 10 for the maintenance and / or installation of the car carriage 6.1. The side legs 12.1, 12.2 extend only between the base leg 11 and the first attachment points 14.1 and thus only over half of the second-longest extension E.2 of the car carriage 6.1. This configuration has, compared to the configuration shown in Fig. 6, the configuration shown provides improved accessibility to the components of the car carriage 6.1. The illustrated parts of the side legs 12.1, 12.2 can be designed as a first part, to which a second part (not shown) can be attached upwards in order to change the configuration of the Fig. 7 in a configuration as in Fig. 2 or Fig. 6 shown. In Fig. 7, means 22, designed as an electric motor, are also arranged for rotating the car carriage 6.1 at the first stop point 14.1 of the first side leg 12.1. The car carriage 6.1 can be rotated or positioned easily and precisely using the means 22.

[0046] Fig.Figure 8 shows another possible configuration of the support frame 10 during assembly of the car carriage 6.1. A mounting support 24, designed as a non-magnetic assembly table, is mounted between the first attachment points 14.1. For example, the secondary part 9 can be placed on this support frame in order to place the correspondingly pre-assembled car carriage 6.1 onto it using a crane 17. The crossbeam 13 can already be used as a crane frame.
