Description

[0001] The present invention relates to a climbing lift that can be scaled with the building's height for the construction of an elevator system. The climbing lift can be installed in an elevator shaft of a building under construction and can scale with the building's height.

[0002] A climbing lift can be used during the construction of a building to transport people and / or loads from one existing floor to another in an elevator shaft that has already been started but is not yet completed. This mode of operation of the climbing lift can also be referred to as "normal" operation of the climbing lift. As the building increases in height, the climbing lift can be gradually positioned higher and higher within the elevator shaft, which can also be referred to as climbing operation of the climbing lift, until the elevator shaft is completed and the climbing lift can be replaced by a "normal" or final lift. In other words, climbing operation is the mode of operation during the construction phase in which the climbing lift grows with the increasing building height using a lifting process.

[0003] Such a climbing lift is known, for example, from EP 3 548 413 B1. The climbing lift comprises an elevator car with which floors already used as residential or commercial spaces can be accessed during the construction phase of the building. The climbing lift also has a protective platform, a machine platform, and an assembly platform. The machine platform, which can be displaced upwards along the elevator shaft during climbing operation, has a drive motor for moving the elevator car. The protective platform can be inserted into the elevator shaft, which is open at the top, by means of a crane. During normal operation of the climbing lift, the protective platform is fixed and stationary in the elevator shaft. The machine platform is suspended in the elevator shaft by means of a support means on the protective platform in such a way that the machine platform can be displaced vertically in the elevator shaft during normal operation by means of the support means.For this purpose, the climbing lift has a lifting device that can be arranged on the machine platform and that is mechanically coupled to the support means such that the lifting device can move the support means, whereby the machine platform is displaced vertically. An assembly platform is arranged between the protective platform and the machine platform. The assembly platform is held by the protective platform by means of a further support means. The assembly platform is in particular suspended in the elevator shaft such that it is vertically displaceable, in particular by means of a further lifting device that is coupled to the further support means. The assembly platform can be used by a fitter to carry out assembly work in the elevator shaft vertically between the machine platform and the protective platform. Another example of a climbing lift is described in EP 3 019 428 B1.

[0004] Installation work in an elevator shaft inherently entails various risks and problems due to the height at which the installers are regularly located and the limited space within the elevator shaft. This applies even to a standard elevator system, i.e., not a climbing lift, and is even more so for climbing lifts. EP 3 325 396 B1 discloses an automated installation device for carrying out installations in an elevator shaft. The automated installation device serves to reduce the risk of personal accidents during installation processes within an elevator shaft. Furthermore, the installation device allows repetitive installation work to be carried out quickly and reliably.After completion of the elevator shaft, the automated assembly device can be suspended from the ceiling of the elevator shaft by means of a suspension device and moved vertically using a suitable lifting device mounted on the ceiling and mechanically coupled to the suspension device. This allows assembly work to be carried out in the completed elevator shaft.

[0005] Among other things, there may be a need for a climbing lift for the installation of an elevator system, which can contribute to the safety of assembly personnel during the installation of the elevator system, to the rapid installation of the elevator system and / or to the reliable installation of the elevator system.

[0006] Such a need can be met by the subject matter according to the independent claim. Advantageous embodiments are defined in the dependent claims and the following description.

[0007] One aspect of the invention relates to a climbing lift for erecting an elevator system having an elevator shaft in a building under construction. The elevator system has an at least partially completed elevator shaft that extends vertically through the building in an at least partially completed building.The climbing lift comprises: a protective platform arranged in the elevator shaft; a first support means mechanically coupled to the protective platform; a machine platform arranged in the elevator shaft below the protective platform and mechanically coupled to the first support means such that the machine platform is vertically displaceable in the elevator shaft by means of the first support means; and an installation arrangement suspended from the protective platform between the protective platform and the machine platform in the elevator shaft so as to be vertically displaceable and having a mechatronic installation device designed to mount at least one component of the elevator system in the elevator shaft.

[0008] The climbing lift can be used during building construction to transport people and / or loads from one floor to another in an elevator shaft that has already been started but is not yet completed. As the building grows taller, the climbing lift can be positioned higher and higher within the elevator shaft until the elevator shaft is completed and the climbing lift can be replaced with a "normal" elevator.

[0009] The installation assembly can, for example, be suspended from the protective platform by means of the first support means. For example, the first support means can be coupled to the installation assembly on the one hand and to the machine platform on the other. Alternatively, the installation assembly can be suspended from the protective platform by means of a second support means, independent of the machine platform.

[0010] The climbing lift can additionally have, for example, an elevator car, a counterweight, a first lifting device, and optionally a second lifting device and / or a drive machine. During normal operation of the climbing lift, the elevator car can serve to accommodate one or more persons and / or loads. The elevator car can have an enclosure surrounding an interior space on all sides and one or more elevator doors that can be opened and closed as desired. The elevator car can, for example, be suspended below the machine platform on the machine platform in a vertically displaceable manner, for example by means of a third support means that is mechanically coupled to the machine platform. The counterweight can be arranged in the elevator shaft and serve to vertically displace and / or hold the elevator car, or support this. The counterweight can, for example, be mechanically coupled to the elevator car via the third support means.For example, the third support means can run from the counterweight to the elevator car via one or more deflection pulleys arranged on the machine platform.

[0011] The first lifting device can, for example, be mechanically coupled to the first support means and serve to move the first support means, whereby the machine platform and / or the installation arrangement can be displaced vertically. If the installation arrangement can be displaced vertically independently of the machine platform by means of the second support means, the second support means can be moved by means of the second lifting device in order to displace the installation arrangement vertically. The drive machine can, for example, be mechanically coupled to the third support means and serve to move the third support means, whereby the elevator car can be displaced vertically. In this context, one or more elongated components such as ropes, belts, or straps that can withstand high tensile loads and are bendable transversely to a tensile direction can be used as the support means.

[0012] The climbing lift can assume various operating states. For example, in a first operating state, the protective platform and the machine platform can be fixed or stationary in their vertical positions in the elevator shaft, such that they cannot be moved vertically in the first operating state. In the first operating state, the elevator car below the machine platform can be moved vertically, for example, to transport people and / or loads. Furthermore, in the first operating state, the robot assembly can be moved vertically. The first operating state represents the "normal" operation of the climbing lift. In a second operating state, the protective platform can be fixed or stationary in its vertical position in the elevator shaft, and the machine platform can be moved vertically, for example, by means of the first support means and the first lifting device.In a third operating mode, the safety platform can be moved vertically. For this purpose, the safety platform can be mechanically coupled to a crane external to the elevator system through the elevator shaft, which is still open at the top, and can be moved vertically within the elevator shaft using the crane. The third operating mode represents the climbing operation of the climbing lift. In this case, one or more other components of the climbing lift can also be moved together with the safety platform. For example, during the third operating mode, the machine platform and / or the installation arrangement can also be moved within the elevator shaft. These components can, for example, be mechanically coupled directly to the safety platform to be moved and can therefore be moved together with it, for example by being lifted together using the crane.Alternatively, the components mentioned can be relocated independently of the protective platform or remain stationary within the elevator shaft during the third operating mode.

[0013] According to one embodiment, the installation arrangement comprises a support component on which the mechatronic installation device is arranged and by means of which the installation arrangement is mechanically coupled to the first support means. The support component thus supports the mechatronic installation device and is suspended from the protective platform. Optionally, the support component can serve to support one, two, or more further components of the climbing lift in addition to the mechatronic installation device. For example, the mechatronic installation device can be configured to use various tools, wherein the tools can be arranged on or at the support component. Furthermore, the mechatronic installation device can process material that can be stored on the support component.The material may include, for example, brackets, dowels, rivets, screws, bolts and / or guide rails for the elevator system.

[0014] According to one embodiment, the support component has a recess that extends vertically through the entire support component. The recess can be used to move the material and / or tools required for assembly in the elevator shaft from the machine platform onto or over the support component. For this purpose, the recess can form a continuous, preferably rectilinear path along which objects can be moved vertically, for example from a partial area of ​​the elevator shaft located below the support component, through the support component, into a partial area of ​​the elevator shaft located above the support component. The recess can have a sufficiently large cross-section to enable material and / or tools to be moved through the recess, for example.For example, the recess can be larger than 100 cm 2 , larger than 500 cm 2 , larger than 1000 cm 2 or even larger than 5000 cm 2 , but preferably smaller than 4 m 2 or smaller than 1 m 2 . The recess can be arranged laterally spaced from an outer circumference of the support component, for example at a distance of more than 10 cm, more than 20 cm or more than 50 cm. The provision of such a recess can be advantageous in particular when there is only little space between a lateral outer side of the support component, which faces a shaft wall of the elevator shaft, and the shaft wall in order to transport the material or tool past the outside of the support component. The recess can therefore serve toto lift the tool, which is initially arranged in the elevator shaft below the installation arrangement, through the installation arrangement so that the material is subsequently arranged in the elevator shaft above the installation arrangement.

[0015] According to one embodiment, the support component comprises a frame-like structure. The frame-like structure can be referred to, for example, as a frame, skeleton, cage, or simply as a structure. The frame-like structure can, for example, comprise a plurality of profile tubes and / or profile supports that are connected to one another, on which the corresponding support means for displacing the installation arrangement is arranged and to which the mechatronic installation device is fastened. These profile tubes or profile supports can be designed and connected to one another in such a way that they delimit the recess of the support component in the lateral direction. In other words, the support component, unlike an elevator car, typically does not require a housing surrounding it on all sides or movable elevator doors. Support components and / or guide components can be arranged on the support component.The support components can be used to support the support component, for example, within the elevator shaft, so that the support component can transfer forces acting on it, such as those caused by the installation layout, to the elevator shaft. The guide components can be used to guide the support component's movement within the elevator shaft.

[0016] According to one embodiment, the mechatronic installation device is designed as an industrial robot and has at least one adjustable robot arm. The industrial robot, and in particular the robot arm, can be designed such that elevator components can be mounted within the elevator shaft, in particular on the shaft walls of the elevator shaft, by means of the robot arm. The elevator components can have or be, for example, fastening means, clamps, brackets, and / or guide rails for vertically guiding the elevator car.

[0017] The robot arm can, for example, have two or more links that are connected to each other by means of corresponding joints and are movable relative to each other. For this purpose, the industrial robot can have one, two, or more electrically controllable actuators that are mechanically coupled to the links. The industrial robot can also have one, two, or more tools that can be used, actuated, and / or controlled by the robot arm. Examples of tools that can be used include drilling tools, milling tools, screwing tools, welding tools, etc.

[0018] Embodiments of the invention are described below with reference to the accompanying drawings, wherein neither the drawings nor the description are to be interpreted as limiting the invention.

[0019] Fig. 1 shows a climbing lift in an elevator shaft, according to an embodiment of the invention.

[0020] The figure is merely schematic and not to scale. Like reference numerals denote like or equivalent features.

[0021] Fig. 1 shows a climbing lift 1 in an elevator shaft 2, according to an embodiment of the invention. The elevator shaft 2 is located in a building 3 that is still under construction, with the elevator shaft 3 not yet completed.

[0022] The scalable climbing lift 1 can be used to construct an elevator system having an elevator shaft 2. The climbing lift 1 can be used, in particular, to transport people and / or loads from one floor of the building 3 to another floor of the building 3 in the elevator shaft 2 using an elevator car 28. For this purpose, a corresponding shaft opening 5 can be formed on each of the floors, through which the elevator shaft 2 can be entered or exited. Furthermore, assembly work in the elevator shaft 2 can be carried out automatically using the climbing lift, as explained in more detail below. As the height of the building 3 increases, the climbing lift 1 can then be positioned ever higher within the elevator shaft 2 until the building 3, and in particular the elevator shaft 2, are completed. The elevator shaft 2 extends vertically through the building 3.The elevator shaft 2 is bounded laterally by several shaft walls 4.

[0023] The climbing lift 1 comprises a protective platform 12, a machine platform 10, at least one first support means 14, and an installation arrangement 16. The protective platform 12 is arranged in the elevator shaft 2. The first support means 14 is mechanically coupled to the protective platform 12. The machine platform 10 is arranged in the elevator shaft 2 below the protective platform 12 and is mechanically coupled to the first support means 14 such that the machine platform 10 can be vertically displaced in the elevator shaft 2 by means of the first support means 14.

[0024] The installation arrangement 16 is suspended in the elevator shaft 2 so as to be vertically displaceable in the vertical direction between the protective platform 12 and the machine platform 10. The installation arrangement 16 can be suspended from the protective platform 10, for example, by means of the first support means 14. For example, the first support means 14 can be coupled to the installation arrangement 16 on the one hand and to the machine platform 10 on the other. Alternatively, the installation arrangement 16 can be suspended from the protective platform 12 by means of a second support means 15. The second support means 15 can be a section of the first support means 14, wherein the first support means 14 is arranged on one side of a deflection pulley 18 and the second support means 15 is arranged on another side of the deflection pulley 18. Alternatively, the second support means 15 can be a support means independent of the first support means 14.The latter allows the mechatronic installation arrangement 16 to be suspended from the protective platform 12 independently of the machine platform 10.

[0025] The installation arrangement 16 comprises a mechatronic installation device 20, which is designed for the automatic assembly of at least one component of the elevator system in the elevator shaft 2. The mechatronic installation device 20 can be designed as an industrial robot and has at least one adjustable robot arm 22. The robot arm 22 can, for example, have two or more links that are connected to one another by means of corresponding joints and are movable relative to one another. For this purpose, the industrial robot can have one, two or more electrically controllable actuators that are mechanically coupled to the links. The industrial robot can also have one, two or more of the tools 23 that can be used and / or actuated by means of the robot arm 22.The industrial robot and in particular the robot arm 22 can be designed such that, by means of the robot arm 22, elevator components can be mounted within the elevator shaft 2, in particular on the shaft walls 4 of the elevator shaft 2. The elevator components can, for example, have or be fastening means, clamps, the brackets 6 and / or the guide rails 7 for vertically guiding the elevator car 28.

[0026] The installation arrangement 16 can have a support component 24 on which the mechatronic installation device 20 is arranged and by means of which the installation arrangement 16 is mechanically coupled to the first support means 14. The support component 24 thus supports the mechatronic installation device 20 and is suspended from the protective platform 12. Optionally, the support component 24 can serve to support one, two, or more further components of the climbing lift 1 in addition to the mechatronic installation device 20. For example, the mechatronic installation device 20 can be configured to use various tools 23, wherein the tools 23 can be arranged on or at the support component 24. Furthermore, the mechatronic installation device 20 can process material that can be stored on the support component 24.The material may, for example, comprise brackets 6, dowels, rivets, screws, bolts, and / or one or more guide rails 7 for the elevator system. The mechatronic installation device 20 may, for example, be configured to arrange the guide rails 7 on one of the shaft walls 4 by means of the brackets 6.

[0027] The support component 24 can have a recess 26 that extends vertically through the entire support component 24. The recess 26 can serve to move the material and / or the tools 23 required for assembly in the elevator shaft 2 from the machine platform 10 onto or over the support component 24. The support component 24 can have a frame-like structure 25. The frame-like structure 25 can be referred to, for example, as a frame, skeleton, or cage. The frame-like structure 25 can, for example, have a plurality of profile tubes and / or profile supports that are connected to one another, on which the corresponding support means 14, 15 for displacing the installation arrangement 16 is arranged, and to which the mechatronic installation device 20 is fastened. These profile tubes orProfile supports can be configured and connected to one another in such a way that they laterally delimit the recess 26 of the support component 24. The support component 24 can have a suspension 26, for example, an eyelet, by means of which the support component 24 is mechanically coupled to the first and / or second support means 14, 15. For example, the corresponding support means 14, 15 can be mechanically coupled to the suspension 26 via a hook 29.

[0028] The climbing lift 1 can additionally have, for example, the elevator car 28, a counterweight 22, a first lifting device 34 and optionally a second lifting device and / or a drive machine 36. The elevator car 28 can serve to accommodate one or more persons and / or loads during normal operation of the climbing lift 1. The elevator car 28 can be suspended, for example, below the machine platform 10 on the machine platform 10 in a vertically displaceable manner, for example by means of a third support means 30 that is mechanically coupled to the machine platform 10. The counterweight 22 can be arranged in the elevator shaft 2 and serve to vertically displace and / or hold the elevator car 28. The counterweight 22 can be mechanically coupled to the elevator car 28, for example via the third support means 30.For example, the third support means 30 can extend from the counterweight 22 via one or more further deflection pulleys 18 arranged on the machine platform 10 to the elevator car 28.

[0029] The first lifting device 34 can, for example, be mechanically coupled to the first support means 14 and serve to move the first support means 14, whereby the machine platform 10 and / or the installation arrangement 16 can be displaced vertically. If the installation arrangement 16 can be displaced vertically by means of the second support means 15 independently of the machine platform 10, the second support means 15 can optionally be moved by means of the second lifting device (not shown) in order to displace the installation arrangement 16 vertically. The drive machine 36 can, for example, be mechanically coupled to the third support means 30 and serve to move the third support means 30, whereby the elevator car 28 can be displaced vertically. For example, the lifting device 36 can be mechanically coupled to the third support means 30 via a traction sheave 38.In contrast, the first support means 14 may be wound more or less on an extension of a motor shaft of the first lifting device 34 depending on a vertical position of the installation arrangement 16.

[0030] The climbing lift 1 can assume various operating states. For example, in a first operating state, the protective platform 12 and the machine platform 10 can be fixedly arranged—in other words, secured, fixed, or attached—at their vertical positions in the elevator shaft 2, so that they cannot be vertically displaced in the first operating state. For example, the protective platform 12 and / or the machine platform 10 can each have two or more support elements 42, by means of which the protective platform 12 or the machine platform 10 can be fixedly coupled to the elevator shaft 2. For example, the support elements 42 can protrude laterally from the protective platform 12 or the machine platform 10 and be placed on supports 40 formed in the shaft walls 4.In the first operating state, the elevator car 28 can be displaced vertically below the machine platform 10, for example, to transport people and / or loads. Furthermore, in the first operating state, the installation assembly 16 can be displaced vertically so that the mechatronic installation device 20 can automatically perform the assembly work in the elevator shaft 3 at different height levels vertically between the machine platform 10 and the safety platform 12. The first operating state represents the "normal" operation of the climbing lift 1.

[0031] In a second operating state of the climbing lift 1, the protective platform 12 can be fixedly arranged at its vertical position in the elevator shaft 2, and the machine platform 10 can be displaced vertically, for example, by means of the first support means 14 and the first lifting device 34. This makes it possible to vary a vertical range to which the persons and / or loads can be transported by the elevator car 28, depending on the construction progress of the building 3.

[0032] In a third operating state, the protective platform 12 can be displaced vertically. For this purpose, the protective platform 12 can be mechanically coupled to the crane (not shown), which is arranged externally with respect to the elevator system, and displaced vertically within the elevator shaft 2 by means of the crane. This makes it possible, depending on the construction progress of the building 3 in the elevator shaft 2, to vary, on the one hand, the vertical range to which the people and / or loads can be transported by the elevator car 28 and, on the other hand, the vertical range in which the mechatronic installation device 20 can automatically perform the assembly work. The third operating state represents a climbing operation of the climbing lift 1.

[0033] The protective platform 12 can have a closable opening (not shown), for example in the form of a hatch, through which components such as guide rails and parts for the shaft equipment can be brought to and transferred from the mechatronic installation arrangement. The closing mechanism of the opening can be controlled by a control unit in such a way that newly arriving nearby components are detected and the closed opening is automatically opened.

[0034] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
