[0006] US 2004 / 0084251 A1 describes a support structure that can be fastened to the upper end of a guide rail. Summary of the invention

[0007] There is a need for an alternative device for carrying a drive motor for an elevator installation. In addition, there is a need for a system for carrying multiple drive motors for an elevator installation, for example, so that a car can be moved using multiple smaller drive motors rather than a single larger drive motor.

[0008] These needs are met by the subject matter of the independent claims. Advantageous embodiments are set forth in the dependent claims, the subsequent description and the drawings.

[0009] A first aspect of the invention relates to a device for supporting a drive motor of an elevator system, the elevator system comprising a shaft connecting a plurality of floors of a building to one another and a car in the shaft that can travel between floors by means of a drive motor. The device comprises: a carrier having a receptacle for fixing the drive motor to the carrier, a bracket and a support. The device is designed or configured such that, in the assembled state of the device, the carrier is fixed with one end to a side wall of the shaft, the receptacle is arranged on a section of the carrier that extends into the shaft, and the bracket is fixed to the side wall, in particular to the same side wall as the fixed carrier, and is arranged below the carrier. Here, the support supports the section of the carrier that extends into the shaft on the section of the bracket that extends into the shaft.

[0010] In the assembled state, the device can be arranged at least partially in the shaft head, ie in the upper end of the shaft. The height of the shaft head can correspond, for example, to the vertical distance from the shaft ceiling to the uppermost floor. However, other assembly positions are also possible.

[0011] For example, the shaft can be bounded by four different side walls, which can be arranged opposite each other in pairs. In other words, the shaft can have a rectangular cross section. When the device is in the assembled state, the carrier and the support can be fixed to one of the four side walls.

[0012] The fixing of carrier and / or support on the side wall can be for example screwed together by screws. It is also possible that a segment of carrier and / or support is embedded in the side wall, for example cast in concrete in the side wall, and another segment of carrier or support stretches out from the side wall.

[0013] For example, the receptacle can be arranged at the free end of the carrier. In this case, the drive motor can be fixed to the carrier via the receptacle in such a way that, viewed in the longitudinal direction of the carrier, the drive motor projects beyond the free end of the carrier in the direction away from the side wall. However, the receptacle can also be arranged at another location of the carrier, for example between the free end and the (fixed) end with which the carrier is fixed to the side wall in the assembled state of the device.

[0014] The carrier can be designed to additionally carry at least one further drive component of the elevator installation, for example a drive battery, a brake chopper, an elevator control, a transmission, a drive wheel and / or a deflection roller.

[0015] The support can be designed to bear at least part of the weight of a carrier fixed to the side wall and having a drive motor (and in addition one or more other drive components). The support can be connected to the carrier on the one hand and to the bracket on the other hand in the assembled state of the device, for example by screwing and / or welding.

[0016] It is possible that the carrier has a horizontal longitudinal direction in the assembled state of the device and / or that the support element has a vertical longitudinal direction in the assembled state of the device.

[0017] By means of the carrier and the support being fixed on the same side wall, the device can be assembled more easily than a carrier structure whose components must be assembled on different side walls. In addition, the device can also be designed to save space.

[0018] A second aspect of the invention relates to a system for carrying a plurality of drive motors of an elevator installation, the elevator installation comprising a shaft connecting a plurality of floors of a building to one another and a car in the shaft that can be moved between the floors by means of drive motors. The system comprises a plurality of devices, each of which is a device as described above and below, and the carrier of each device has a receptacle for fixing one of the drive motors on the carrier.

[0019] In other words, the system can include a separate device for each drive motor. These devices can, for example, be mounted independently of each other.

[0020] It is possible that in the assembled state of the system, the carriers can be arranged at the same height in the shaft. Additionally or alternatively, in the assembled state of the system, the supports can be arranged at the same height in the shaft. However, also conceivable are embodiments in which the height positions of the carriers or supports differ significantly from one another.

[0021] Such a system enables a simple and space-saving installation of a plurality of drive motors in a shaft, for example in the shaft head. Thus, a plurality of smaller drive motors can be used instead of a single larger drive motor to move the car, which can have a positive effect on manufacturing costs and / or maintenance and / or repair costs.

[0022] A third aspect of the invention relates to an elevator installation comprising a shaft connecting a plurality of floors of a building to one another and a car which can travel between the floors in the shaft.

[0023] The elevator installation further comprises a drive motor for moving the car and the device described above, wherein the drive motor is fastened to the carrier via a receptacle.

[0024] Alternatively, the elevator installation further comprises a plurality of drive motors for moving the cage and the system described in this context, wherein each drive motor is fastened to one of the carriers via one of the receptacles.

[0025] In addition, the elevator installation can include a counterweight connected to the car via a sling, which lowers when the car is raised and rises when the car is lowered. Here, one or more drive motors can be designed to move the sling.

[0026] A fourth aspect of the invention relates to a method for assembling a device for carrying a drive motor for an elevator installation, in particular a device as described above, wherein the elevator installation comprises a shaft connecting a plurality of floors of a building to one another and a car in the shaft that can be moved between the floors by means of a drive motor. The method comprises the following steps: providing a support, a support element and a carrier having a receptacle for fixing the drive motor on the support; fixing the support and the carrier with one end thereof to a side wall, in particular to the same side wall and / or to the ceiling of the shaft, wherein the support fixed to the side wall is arranged below the carrier, in particular fixed to the side wall, and the receptacle is arranged on a section of the carrier, in particular fixed to the side wall, that projects into the shaft; connecting the support element to the carrier and the support element, so that the support element supports the section of the carrier that projects into the shaft on the section of the support that projects into the shaft.

[0027] The above steps may be performed in the order given, or in an order different from the order given.

[0028] It should be pointed out that features of the apparatus described above and below may also be features of the method (and vice versa).

[0029] The embodiments of the present invention can be considered to be based on the concepts and knowledge described below. These embodiments are not intended to limit the scope of the present invention.

[0030] According to one embodiment, the support can be formed by a longitudinal segment of a guide rail for guiding the car in the longitudinal direction of the shaft. In the assembled state of the device, the longitudinal segment can be fixed on the carrier on the one hand and on the support on the other hand. As a result, no additional components are required to support the carrier on the support.

[0031] According to one embodiment, the guide rail can be a hollow rail. Such a guide rail is particularly strong and stable.

[0032] According to one embodiment, the longitudinal segment can be an end segment of the guide rail. In other words, in the assembled state of the device, the carrier can be arranged on the upper end of the guide rail. For example, the carrier can be placed against the upper end of the guide rail.

[0033] According to one embodiment, in the assembled state of the device, the support can be anchored in the floor and / or in the side wall in the immediate vicinity of the floor of one of the floors. In this case, the support can be connected to the floor directly and / or indirectly, i.e. via at least one connecting element, for example in the form of a carrier or a plate. The floor can be, for example, the floor of the uppermost floor. This allows a particularly stable fixing of the support to the side wall.

[0034] According to one embodiment, in the assembled state of the device, the carrier can be placed against the upper end of the support element. Here, the upper end of the support element can contact the underside of the carrier.

[0035] However, the lower side of the carrier can also be connected to the upper end of the support via at least one connecting element, for example in the form of an intermediate plate arranged between the carrier and the support. In the assembled state of the device, the connecting element can be fixed to the carrier and / or the support, for example screwed thereto and / or welded thereto. The connecting element can also include a fixing section for additionally fixing the drive motor to the connecting element. This enables the drive motor to be supported in a statically defined manner at two assembly points, namely the receptacle on the carrier and the fixing section.

[0036] According to one embodiment, the device may further comprise an additional support member, which in the assembled state of the device additionally supports the section of the carrier extending into the shaft on the section of the support extending into the shaft. Similar to the support member, the additional support member can be connected to the carrier on the one hand and to the support on the other hand in the assembled state of the device. In the assembled state of the device, the additional support member can extend horizontally at least in sections between the support member and the side wall, and / or vertically at least in sections between the carrier and the support. By using a plurality of, i.e. two or more, support members for support, the support member can be made lighter and / or simpler than when only a single support member is used. This also makes the support more reliable.

[0037] According to one embodiment, the device can also include a plate-shaped wall element which is designed in such a way that, in the assembled state of the device, it extends at least in sections between the support and the side wall.

[0038] According to one embodiment, the wall element can be designed in such a way that, in the assembled state of the device, it covers at least 50%, preferably at least 75%, of the surface defined in the horizontal direction by the support and the side walls and in the vertical direction by the carrier and the support. This is advantageous for safety and / or aesthetic reasons.

[0039] According to one embodiment, the width of the section of the wall element extending between the support and the side wall in the horizontal direction can be at least 50%, preferably at least 75% of the horizontal distance from the support to the side wall. This is advantageous for weight and / or stability reasons.

[0040] According to one embodiment, the wall element can have a plurality of recesses, the respective width of which can be at least 25% of the width of the wall element, preferably at least 50% of the width of the wall element, and / or the respective height of which can be at least 10% of the height of the wall element, preferably at least 25% of the height of the wall element. As a result, the weight of the wall element can be significantly reduced.

[0041] According to one embodiment, the wall element can be a sheet metal component. This enables cost-effective production of the wall element.

[0042] According to one embodiment, the additional support can be formed by a wall element. Thus, apart from the wall element, no further components are required to additionally support the carrier on the support.

[0043] According to one embodiment, the end of the carrier that is fixed to the side wall and / or the ceiling can be fixed to the side wall and / or the ceiling by at least one vibration-damping intermediate element. Such an intermediate element can be a rubber component or include a rubber component, for example. As a result, undesirable vibrations and / or noises generated during the operation of the drive motor can be significantly weakened or avoided.

[0044] According to one embodiment, in the assembled state of the system, the supports of the different devices can be fixed on the same side wall of the shaft. In other words, all supports and brackets of the system can be fixed on the same side wall of the shaft.

[0045] Alternatively, at least one carrier may be fastened to a different side wall than one or more of the remaining carriers and / or at least one support may be fastened to a different side wall than one or more of the remaining supports.

[0046] According to one embodiment, in the assembled state of the system, the carriers can be connected to one another on their sections extending into the shaft by at least one connecting element to form a frame. The connecting element can be, for example, plate-shaped or in the form of a carrier. Thus, the rigidity of the carrier can be significantly increased with little structural effort compared to a design in which the carriers are not connected to one another to form a frame.

[0047] Similarly, in the assembled state of the system, the supports can be connected to one another by connecting elements, for example in the form of plates or carriers. In this case, the supports can be fixed to the side walls by means of (common) connecting elements. The connecting elements can also be designed to anchor the supports in the floor of one of the floors (see above). For this purpose, the connecting elements can be fixed at least partially to the floor, for example to the front edge of the floor which adjoins the side wall or extends through the side wall into the shaft.

[0054] Figure 1 The elevator system 1 is shown, which comprises a shaft 7 connecting a plurality of floors 3 of a building 5 to one another and a car 11 which can be moved in the shaft 7 by means of a drive motor 9. The elevator system 1 also comprises a device 13 for positioning the drive motor 9 in the shaft 7, here in the shaft head.

[0055] The device 13 includes a carrier 15, a bracket 17 and a support 19. Figure 1 In the illustrated assembled state, the carrier 15 is fastened with one end to the side wall 21 of the shaft 7, so that a section of the carrier 15 projects from the side wall 21 into the shaft 7. In the longitudinal section, which is horizontal here, the carrier 15 has a receptacle 23 for fastening the drive motor 9 to the carrier 15. Figure 1 As shown, the receptacle 23 can be arranged at the free end of the section of the carrier 15 that projects into the shaft 7 .

[0056] The support 17 is fixed to the same side wall 21 as the fixed carrier 15 and is located below the carrier 15. In this case, the support 17 can be located below a door opening and the carrier 15 can be located above a door opening through which a person can enter the shaft 7 from one of the floors 3.

[0057] The support 19 is connected to the section of the carrier 15 extending into the shaft 7 on the one hand and to the section of the support 17 extending into the shaft 7 on the other hand, for example by screwing and / or welding. Thus, the carrier 15 is supported on the support 17 via the support 19 .

[0058] The drive motor 9 is fixed to the carrier 15 via a receptacle 23. In this example, the drive motor 9 is carried only by the device 13, ie held in a defined position in the shaft 7. The receptacle 23 can additionally be supported on the support 19 and / or the bracket 17.

[0059] The drive motor 9 can include a housing 25 and be fixed to the receptacle 23 by its housing 25. Additional drive components can be arranged in and / or on the housing 25, such as a transmission and / or a drive wheel for moving a sling 27 connected to the car 11 and / or the counterweight.

[0060] A so-called power supply block 29 (also referred to in English as a power block) can be additionally fixed to the protruding part of the carrier 15, for example, between the support 19 and the side wall 21. Such a power supply block 29 can, for example, include a battery, a brake chopper, an elevator controller or a combination of at least two of these examples.

[0061] In this example, the support 19 is formed by a longitudinal segment of a guide rail 19, which is preferably in the form of a hollow rail for guiding the car 11 in the longitudinal direction of the shaft 7. Here, the carrier 15 can rest on the upper end of the guide rail 19 as shown. The guide rail 19 can be designed to additionally support the support 17.

[0062] The bracket 17 can be anchored in the floor 33 of one of the floors 3, here the uppermost floor 3. Alternatively or additionally, the bracket 17 can be anchored in a section of the side wall 21 which is located outside the floor 33, for example adjacent to the floor 33.

[0063] The elevator installation 1 may also comprise two or more (preferably identical) instances of the above-mentioned device 13, which then form a system 35 for carrying two or more drive motors 9 of the elevator installation 1 (see Figure 2 and Figure 3 ). In this case, each drive motor 9 can be connected to one of the carriers 15 via a receptacle 23 , ie each drive motor 9 can be carried by its own device 13 .

[0064] like Figure 2 and Figure 3 As shown, the supports 15 of the system 35 can be connected to one another at their sections projecting into the shaft 7 by at least one connecting element 37 , here in the form of a connecting plate, in order to form a particularly rotationally rigid frame.

[0065] In a similar manner, the supports 17 of the system 35 can be connected to one another by at least one connecting member, here in the form of a transverse carrier 39. In this example, each support 17 is connected at one of its ends to a transverse carrier 39, which on the other hand can be fixed to the side wall 21, preferably anchored in the floor 33. On the other hand, at its other end, the support 17 is connected to one of the supports 19, here to one of the rails 19.

[0066] It is possible that each carrier 15 can be supported on the corresponding support 17 by means of an additional support element 41, wherein the additional support element 41 can be fixed on the one hand to the section of the carrier 15 extending into the shaft 7 and on the other hand to the section of the support 17 extending into the shaft. Furthermore, the additional support element 41 can be fixed on the support element 19 and / or the side wall 21.

[0067] like Figure 2 As shown, the additional support member 41 can be designed as a substantially closed plate-like wall element 41, which is in the form of a plate component and which, in the assembled state of the device 13, covers a large part of the surface defined in the horizontal direction by the support member 19 and the side walls 21 and in the vertical direction by the carrier 15 and the bracket 17, i.e. at least 50% or even at least 75%.

[0068] Here, the width of the section of the wall element 41 extending between the support 19 and the side wall 21 can be the horizontal distance A from the support 19 to the side wall 21 (see Figure 1 ) of at least 50% or even at least 75%.

[0069] like Figure 3 As shown, for reasons of weight and / or stability, the wall element 41 can have a plurality (here three) relatively large recesses 43, the respective width of which can be at least 25% or even at least 50% of the width of the wall element 41 (or the distance A), and / or the respective height of which can be at least 10% or even at least 25% of the height of the wall element 41 (or the vertical distance from the bracket 17 to the carrier 15).

[0070] In the assembled state of the system 35, the carriers 15 of the different devices 13 can be arranged at the same height in the shaft 7. Additionally or alternatively, in the assembled state of the system 35, the supports 17 of the different devices 13 can be arranged at the same height in the shaft 7.

[0071] In the assembled state of the system 35 , the car 11 can be arranged between the supports 19 or guide rails 19 .

[0072] like Figure 4 As shown, the carrier 15 can also be connected to the side wall 21 at its fixed end by at least one vibration-damping intermediate piece 59. In this example, the carrier 15 has a flange 61 at its fixed end, which can be screwed with a matching plate 63 fixed to the side wall 21, wherein the flange 61 and the matching plate 63 are not in direct contact in the screwed state, but are connected to each other through a plurality of intermediate pieces 59. The intermediate pieces 59 can be designed, for example, as rubber washers, and the screws can pass through these rubber washers respectively.

[0073] Finally, it should be pointed out that terms such as "comprises", "comprising", "having", "with" etc. do not exclude other elements or steps, and indefinite articles such as "a" or "an" etc. do not exclude a plurality. It should also be noted that features or steps described with reference to one of the above embodiments may also be used in combination with features or steps described with reference to other above embodiments. Reference signs in the claims shall not be construed as limiting the scope of the subject matter defined by the claims.
