Description

[0001] Device for supporting a drive motor of an elevator system

[0002] The present invention relates to a device for supporting a drive motor of an elevator installation. Furthermore, the invention relates to a method for mounting the device. Furthermore, the invention relates to a system for supporting multiple drive motors of an elevator installation, as well as to an elevator installation.

[0003] An elevator system used to transport people and / or goods in buildings may include a drive motor for raising and / or lowering the car and / or a counterweight connected to the car. Such a drive motor may be arranged, for example, in a shaft head by means of a support structure.

[0004] EP 2 361 214 B1 describes a support structure formed by a cross member arranged in the shaft and a longitudinal member for supporting the cross member on a supporting element of the shaft.

[0005] US 6,006,865 describes a support structure that can be swung into the shaft for maintenance and repair purposes.

[0006] US 6,446,762 Bl describes a support structure in the form of a two-part frame that can be attached to an upper end of the shaft.

[0007] US 2004 / 0084251 A1 describes a support structure that can be attached to an upper end of a guide rail.

[0008] There may be a need for an alternative device for supporting a drive motor of an elevator system. Furthermore, there may be a need for a system for supporting multiple drive motors of an elevator system, for example, to enable the use of multiple smaller drive motors instead of a single larger drive motor to move the car.

[0009] These needs can be met with the subject matter of the independent claims. Advantageous embodiments are set out in the dependent claims, the following description and the accompanying figures. A first aspect of the invention relates to a device for supporting a drive motor of an elevator installation, which comprises a shaft connecting several floors of a building and a car that can be moved in the shaft between the floors by means of the drive motor. The device comprises a support with a receptacle for fastening the drive motor to the support. The device is designed or configured such that, in the assembled state of the device, the support is fastened by one of its ends to a side wall and / or ceiling of the shaft, and the receptacle is arranged on a section of the support that projects into the shaft.The mount is designed as a suspension for suspended mounting of the drive motor on the support. The mount is preferably hook-shaped so that a pin protruding from a housing of the drive motor can be hooked into the mount.

[0010] This simplifies the installation of the drive motor. In particular, it can be installed by a single person.

[0011] According to one embodiment, the device may further comprise a securing mechanism for securing the pin suspended in the receptacle.

[0012] This prevents the drive from accidentally coming loose from the mount.

[0013] According to one embodiment, the securing mechanism can comprise an arm which is mounted on the carrier and is in particular hook-shaped and can be moved, preferably rotatably, between a first position and a second position.

[0014] The hook-shaped design of the arm allows for a counterpart to the preferably hook-shaped receptacle. The preferably hook-shaped receptacle and the preferably hook-shaped arm can be configured or arranged / movably mounted on the support in such a way that the receptacle and the arm at least partially, preferably substantially completely, enclose / can enclose the pin of the drive motor.

[0015] Hook-shaped means a shape that runs at least partially with a certain radius. Hook-shaped refers, in particular, to a shape that is essentially semicircular.

[0016] This prevents the drive from being accidentally released from the receptacle. According to one embodiment, the arm can comprise an actuating portion and a securing portion, wherein the securing portion releases the receptacle in the first position, and the actuating portion is arranged in the first position such that the pin presses against the actuating portion when hooked into the receptacle, thereby moving the arm toward the second position, preferably into the second position. In the second position, the securing portion at least partially encompasses the pin hooked into the receptacle to prevent the pin from slipping out of the receptacle.

[0017] This allows the locking mechanism to be automatically activated when the drive motor is hooked into the mount. This simplifies the installation of the drive motor and also prevents installation errors that can occur when using a manually operated locking mechanism.

[0018] The drive motor can, for example, be suspended from the support when the pin is hooked into the receptacle. In other words, the center of gravity of the drive motor attached to the support can be below the pin hooked into the receptacle. In addition to the pin, the housing of the drive motor can be connected to the support at at least one other point (which can be located, for example, below the pin hooked into the receptacle), for example, to a connecting part connected to the support and / or the support (see above).

[0019] The pin can, for example, be part of a vibration-damping bearing for mounting the drive motor on the carrier.

[0020] For example, the housing of the drive motor can have a bearing bushing with a pin protruding from both sides. Accordingly, the support's receptacle can comprise two hook-shaped sections for hooking in the two pins. The securing mechanism can comprise a separate arm for each of the two hook-shaped sections. The pins can, for example, be the ends of an axle that passes through the bearing bushing and can be connected to the bearing bushing via an elastomer material (such a bearing is also referred to as a spherical bearing). In the assembled state, the device can be arranged at least partially in a shaft head, i.e. in an upper end of the shaft. The height of the shaft head can, for example, correspond to a vertical distance from a ceiling of the shaft to a floor of an uppermost storey. However, other installation locations are also possible.

[0021] For example, the shaft can be defined by four different side walls, which can be positioned opposite each other in pairs. In other words, the shaft can have a rectangular cross-section. The support and the bracket can be attached to one of these four side walls when the device is assembled.

[0022] The support and / or bracket can be attached to the side wall by screwing, for example. It is also possible for one section of the support and / or bracket to be embedded in the side wall, for example, by concrete, while another section of the support or bracket protrudes from the side wall.

[0023] The mount can, for example, be located at a free end of the support. The drive motor can be attached to the support via the mount such that, viewed in the longitudinal direction of the support, the drive motor protrudes beyond the free end of the support in a direction away from the side wall. However, the mount can also be located at a different location on the support, for example, between the free end and the (attached) end with which the support is attached to the side wall when the device is mounted.

[0024] The support can be designed to additionally support at least one further drive component of the elevator system, for example a drive battery, a brake chopper, an elevator control system, a gear, a traction sheave and / or a deflection pulley.

[0025] The support can be designed to bear at least part of the weight of the support attached to the side wall and containing the drive motor (and additionally one or more other drive components). In the assembled state of the device, the support can be connected, for example, by screwing and / or welding, to the support on the one hand and to the console on the other.

[0026] It is possible that the carrier has a horizontal longitudinal direction in the assembled state of the device and / or the support has a vertical longitudinal direction in the assembled state of the device.

[0027] Because the support and bracket are attached to the same side wall, the fixture is easier to install than with support structures whose components must be mounted on different side walls. This also allows for a more space-saving design.

[0028] A second aspect of the invention relates to a system for supporting multiple drive motors of an elevator system comprising a shaft connecting several floors of a building and a car movable within the shaft between the floors by means of the drive motors. The system comprises multiple devices, each device being the device described above and below, and the support of each device having a receptacle for attaching one of the drive motors to the support.

[0029] In other words, the system can include a separate device for each drive motor. The devices can, for example, be mountable independently of one another.

[0030] It is possible for the supports to be arranged at the same height in the shaft when the system is assembled. Additionally or alternatively, the brackets can be arranged at the same height in the shaft when the system is assembled. However, a design in which the height positions of the supports or brackets differ significantly from each other is also conceivable.

[0031] Such a system enables the simple and space-saving installation of multiple drive motors in the shaft, for example, in the shaft head. This allows several smaller drive motors to be used to move the car instead of a single larger drive motor, which can have a positive impact on manufacturing costs and / or maintenance and / or repair requirements.

[0032] A third aspect of the invention relates to an elevator system comprising a shaft connecting several floors of a building and a car that can be moved in the shaft between the floors.

[0033] The elevator system further comprises a drive motor for moving the car and the device described above and below, wherein the drive motor is attached to the support via the holder.

[0034] Alternatively, the elevator system further comprises a plurality of drive motors for moving the car and the system described above and below, wherein each drive motor is attached to one of the supports via one of the mounts. Furthermore, the elevator system can comprise a counterweight coupled to the car via support means, which is lowered when the car is raised and raised when the car is lowered. The drive motor(s) can be configured to displace the support means.

[0035] A fourth aspect of the invention relates to a method for mounting a device for supporting a drive motor of an elevator installation, in particular the device described above and below, wherein the elevator installation comprises a shaft connecting several floors of a building and a car movable in the shaft between the floors by means of the drive motor.The method comprises the following steps: providing a console, a support, and a beam with a receptacle for attaching the drive motor to the beam; attaching the console and the beam by one of its ends to the side wall, in particular the same side wall, and / or the ceiling of the shaft, wherein the console attached to the side wall is arranged below the beam, in particular attached to the side wall, and the receptacle is arranged on a section of the beam, in particular attached to the side wall, that projects into the shaft; connecting the support to the beam and the console, such that the support supports the section of the beam that projects into the shaft on a section of the console that projects into the shaft.

[0036] The above steps can be performed in the order given or in a different order than the order given.

[0037] It should be noted that features of the device as described above and below may also be features of the method (and vice versa).

[0038] Embodiments of the invention may be considered based on the ideas and findings described below. These embodiments are not to be construed as limiting the scope of the invention.

[0039] According to one embodiment, the support can be formed by a longitudinal section of a guide rail for guiding the car in the longitudinal direction of the shaft. When the device is assembled, the longitudinal section can be attached to the support on one side and to the console on the other. Thus, no additional component is required to support the support on the console. According to one embodiment, the guide rail can be a hollow rail. Such a guide rail is particularly rigid and stable.

[0040] According to one embodiment, the longitudinal section can be an end section of the guide rail. In other words, the support can be arranged at an upper end of the guide rail when the device is assembled. For example, the support can rest on the upper end of the guide rail.

[0041] According to one embodiment, the bracket, when the device is mounted, can be anchored in a floor and / or on a side wall directly at the floor of one of the floors. The bracket can be connected to the floor directly and / or indirectly, i.e., via at least one connecting part, for example, in the form of a support or a plate. The floor can be, for example, the floor of the topmost floor. This enables a particularly stable attachment of the bracket to the side wall.

[0042] According to one embodiment, the carrier can rest on an upper end of the support when the device is mounted. The upper end of the support can touch an underside of the carrier.

[0043] The underside of the support can also be connected to the upper end of the support via at least one connecting part, for example in the form of an intermediate plate arranged between the support and the support. When the device is assembled, the connecting part can be attached to the support and / or the support, for example, screwed and / or welded thereto. The connecting part can also include a fastening section for additionally fastening the drive motor to the connecting part. This enables statically determined mounting of the drive motor at two mounting points, namely the mount on the support and the fastening section.

[0044] According to one embodiment, the device can further comprise an additional support which, when the device is in the assembled state, additionally supports the section of the carrier projecting into the shaft on the section of the console projecting into the shaft. Similar to the support, the additional support can be connected to the carrier on the one hand and to the console on the other hand when the device is in the assembled state. The additional support can extend horizontally at least in sections between the support and the side wall and / or vertically at least in sections between the carrier and the console when the device is in the assembled state. By using several, i.e. two or more than two, supports for support, the supports can each be lighter and / or simpler than if only a single support is used. In addition, the support is therefore more secure.

[0045] According to one embodiment, the device may further comprise a plate-like wall element which is designed such that, in the assembled state of the device, it extends at least partially between the support and the side wall.

[0046] According to one embodiment, the wall element can be designed such that, in the assembled state of the device, it conceals at least 50%, preferably at least 75%, of an area bounded horizontally by the support and the side wall and vertically by the beam and the console. This can be advantageous for safety and / or aesthetic reasons.

[0047] According to one embodiment, the width of a section of the wall element extending between the support and the side wall can be at least 50%, preferably at least 75%, of the horizontal distance between the support and the side wall. This can be advantageous for weight and / or stability reasons.

[0048] According to one embodiment, the wall element can have a plurality of recesses, the respective width of which can be at least 25%, preferably at least 50%, of the width of the wall element and / or the respective height of which can be at least 10%, preferably at least 25%, of the height of the wall element. This allows the weight of the wall element to be significantly reduced.

[0049] According to one embodiment, the wall element can be a sheet metal part. This allows for cost-effective production of the wall element.

[0050] According to one embodiment, the additional support can be formed by the wall element. Thus, no additional component is required besides the wall element to additionally support the beam on the bracket.

[0051] According to one embodiment, the end of the support attached to the side wall and / or ceiling can be attached to the side wall and / or ceiling via at least one vibration-damping intermediate piece. Such an intermediate piece can be or comprise a rubber part, for example. Thus, unwanted vibrations and / or noise during operation of the drive motor can be noticeably reduced or eliminated.

[0052] According to one embodiment, the supports of different devices can be attached to the same side wall of the shaft when the system is assembled. In other words, all supports and brackets of the system can be attached to the same side wall of the shaft.

[0053] Alternatively, at least one of the supports may be attached to a different side wall than the remaining support(s) and / or at least one of the brackets may be attached to a different side wall than the remaining bracket(s).

[0054] According to one embodiment, in the assembled state of the system, the beams can be connected to one another at their sections extending into the shaft via at least one connecting part to form a frame. The connecting part can be, for example, plate-shaped or beam-shaped. Thus, the rigidity of the beams can be significantly increased with minimal design effort compared to designs in which the beams are not connected to one another to form a frame.

[0055] Similarly, the brackets can be connected to one another in the assembled state of the system via a connecting part, for example, a plate- or beam-shaped one. In this case, the brackets can be attached to the side wall via the (common) connecting part. The connecting part can also be designed to anchor the brackets in a floor of one of the floors (see above). For this purpose, the connecting part can be at least partially attached to the floor, for example, to an end edge of the floor adjacent to the side wall or extending beyond the side wall into the shaft.

[0056] Another aspect relates to a method for mounting a drive motor to a device for supporting a drive motor of an elevator system. This method comprises the steps of providing a device as described above and below; and suspending a pin projecting from a drive motor into the receptacle.

[0057] Embodiments of the invention are described below with reference to the accompanying drawings. Neither the description nor the drawings are to be understood as limiting the scope of the invention. Fig. 1 shows a side view of an end section of a support of a device according to an embodiment of the invention, said end section having a hook-shaped receptacle, and a drive motor of an elevator system being hooked into the receptacle.

[0058] Fig. 2 shows the recording from Fig. 1 with the attached drive motor in side view.

[0060] Fig. 4 shows a perspective view of a system supporting two drive motors of an elevator installation according to an embodiment of the invention.

[0061] Fig. 5 shows a system supporting two drive motors of an elevator installation according to an alternative embodiment of the invention in a perspective view.

[0062] Fig. 6 shows a plan view of a support of a device according to an embodiment of the invention, which is fastened to a shaft wall via several vibration-damping intermediate pieces.

[0063] The drawings are purely schematic and not to scale. Where identical reference symbols are used in different drawings, these reference symbols indicate identical or equivalent features.

[0064] Fig. 1 shows an elevator system 1 comprising a shaft 7 connecting several floors 3 of a building 5 and a car 11 movable within the shaft 7 by means of a drive motor 9. Furthermore, the elevator system 1 comprises a device 13 for positioning the drive motor 9 in the shaft 7, here in a shaft head.

[0065] The device 13 comprises a support 15, a console 17 and a support 19. In the assembled state of the device 13 shown in Fig. 1, the support 15 is fastened by one of its ends to a side wall 21 of the shaft 7, so that a section of the support 15 projects from the side wall 21 into the shaft 7. In this section, which here has a horizontal longitudinal direction, the support 15 has a receptacle 23 for attaching the drive motor 9 to the support 15. As shown in Fig. 1, the receptacle 23 can be arranged at a free end of the section of the support 15 projecting into the shaft 7. The console 17 is attached to the same side wall 21 as the support 15 and is located below the support 15. The console 17 can be located below and the support 15 above a door opening through which the shaft 7 is accessible to people from one of the floors 3.

[0066] The support 19 is connected, for example, by screwing and / or welding, to the section of the beam 15 that extends into the shaft 7 and to a section of the bracket 17 that extends into the shaft 7. Thus, the beam 15 is supported on the bracket 17 via the support 19.

[0067] The drive motor 9 is attached to the support 15 via the mount 23. In this example, the drive motor 9 is carried exclusively by the device 13, i.e., held at a defined position in the shaft 7. The mount 23 can additionally be supported by the support 19 and / or the bracket 17.

[0068] The drive motor 9 may comprise a housing 25 and be secured to the receptacle 23 via its housing 25. Additional drive components, such as a gear and / or a traction sheave for displacing a support means 27 connected to the cabin 11 and / or a counterweight, may be arranged in and / or on the housing 25.

[0069] A so-called power block 29 can additionally be attached to the section of the support 15 that extends into the shaft 7, for example, between the support 19 and the side wall 21. Such a power block 29 can, for example, comprise a battery, a brake chopper, an elevator control system, or a combination of at least two of these examples.

[0070] In this example, the support 19 is formed by a longitudinal section of a guide rail 19, preferably in the form of a hollow rail, for guiding the car 11 in the longitudinal direction of the shaft 7. The support 15, as shown here, can rest on the upper end of the guide rail 19. The guide rail 19 can be designed to additionally support the bracket 17.

[0071] The bracket 17 can be anchored in a floor 33 of one of the floors 3, here the top floor 3. Alternatively or additionally, the bracket 17 can be anchored in a section of the side wall 21 located outside the floor 33, for example, adjacent to the floor 33. The elevator installation 1 can also comprise two or more than two (preferably identical) examples of the device 13 described above, which then form a system 35 for supporting two or more than two drive motors 9 of the elevator installation 1 (see Fig. 2 and Fig. 3). Each of the drive motors 9 can be connected to one of the supports 15 via one of the receptacles 23, i.e., each drive motor 9 can be supported by its own device 13.

[0072] As can be seen in Fig. 2 and Fig. 3, the supports 15 of the system 35 can be connected to one another at their sections projecting into the shaft 7 via at least one connecting part 37, here in the form of a connecting plate, to form a particularly torsion-resistant frame.

[0073] Similarly, the brackets 17 of the system 35 can be connected to one another via at least one connecting part, here in the form of a cross member 39. In this example, each bracket 17 is connected to the cross member 39 at one of its ends, while the cross member 39 can be attached to the side wall 21, preferably anchored to the floor 33. At its other end, however, the bracket 17 is connected to one of the supports 19, here to one of the guide rails 19.

[0074] It is possible for each support 15 to be supported on the respective bracket 17 via an additional support 41, wherein the additional support 41 can be attached, on the one hand, to the section of the support 15 projecting into the shaft 7 and, on the other hand, to the section of the bracket 17 projecting into the shaft. Furthermore, the additional support 41 can be attached to the support 19 and / or the side wall 21.

[0075] The additional support 41 can, as shown in Fig. 2, be designed as a largely closed, plate-like wall element 41 in the form of a sheet metal part which, in the assembled state of the device 13, covers a large part, ie at least 50% or even at least 75% of an area which is delimited in the horizontal direction by the support 19 and the side wall 21 and in the vertical direction by the carrier 15 and the console 17.

[0076] In this case, a section of the wall element 41 extending between the support 19 and the side wall 21 can have a width which is at least 50% or even at least 75% of a horizontal distance A (see Fig. 1) between the support 19 and the side wall 21. As shown in Fig. 3, for reasons of weight and / or stability, the wall element 41 can have several (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 a vertical distance of the console 17 to the support 15).

[0077] The supports 15 of different devices 13 can be arranged at the same height in the shaft 7 when the system 35 is assembled. Additionally or alternatively, the brackets 17 of different devices 13 can be arranged at the same height in the shaft 7 when the system 35 is assembled.

[0078] In the assembled state of the system 35, the cabin 11 can be arranged between the supports 19 or guide rails 19.

[0079] As shown in Fig. 4, the support 15 can also be coupled to the side wall 21 at its attached end via at least one vibration-damping intermediate piece 59. In this example, the support 15 has a flange 61 at its attached end, which can be screwed to a counterplate 63 attached to the side wall 21. In the screwed state, the flange 61 and the counterplate 63 do not directly touch each other, but are coupled to each other via several intermediate pieces 59. The intermediate pieces 59 can, for example, be designed as rubber spacers, through each of which a screw can be passed.

[0080] Finally, it should be noted that terms such as "comprising," "including," "including," "having," etc., do not exclude other elements or steps, and indefinite articles 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 features or steps described with reference to other of the above embodiments. Reference signs in the claims are not to be understood as limiting the scope of the subject matter defined by the claims.
