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 for moving the car. Furthermore, there may be a need for a guide rail consisting of multiple identical guide rail sections and a support supported on the guide rail, which enables the guidance of a car brake mounted on the car roof. These needs can be met by the subject matter of the independent claims. Advantageous embodiments are set forth in the dependent claims, the following description, and the accompanying figures.

[0009] A first aspect of the invention relates to a device for supporting a drive motor of an elevator system, 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, with a car brake attached to the car, and a support with a receptacle for attaching the drive motor to the support. A guide element for guiding the car brake is attached to the support.

[0010] The guide element enables the car brake(s) mounted on the car roof to be guided in the last section (while the car brake is at the height of the girder and the car approaches the girder height). This requirement arises when the girder is supported on the guide rail and the brake is arranged on the car roof. The guide element ensures that the car brake is safely guided in all possible positions in the shaft. The guide element is therefore essentially an extension of the guide rail running along the girder. This makes it possible to use a guide rail consisting of several identical rail sections and a girder supported on the uppermost rail section, while still allowing the car brake arranged on the car roof to be guided in all positions. This makes it possible to provide a modular low-head elevator with a car brake.

[0011] When installed, the device can be arranged at least partially in a shaft head, i.e., at the upper end of the shaft. The height of the shaft head can, for example, correspond to the vertical distance between the ceiling of the shaft and the floor of an uppermost floor. However, other installation locations are also possible.

[0012] The shaft can, for example, 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 can be attached to one of these four side walls when the device is assembled.

[0013] The support can be attached to the side wall, for example, by screwing. It is also possible for a section of the support to be recessed into the side wall, for example cast in concrete, while another section of the support protrudes from the side wall. The holder can be arranged, for example, at a free end of the support. The drive motor can be attached to the support via the holder in such a way 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 holder can also be arranged at a different point 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 assembled.

[0014] 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.

[0015] According to one embodiment, the guide element consists of a sheet metal profile attached to the support. The sheet metal profile has a guide section with a guide surface for guiding the cabin brake. Furthermore, the sheet metal profile has a fastening section with a fastening surface, preferably running substantially parallel to the guide surface, for fastening the guide element to the support.

[0016] According to one embodiment, the guide element further comprises a connecting section for connecting the guide section and the fastening section. The connecting section preferably runs perpendicular to the guide section and / or fastening section.

[0017] According to one embodiment, the guide element is designed as a one-piece and bent sheet metal stamping.

[0018] 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 another point in the shaft on the other.

[0019] According to one embodiment, the guide rail has a guide surface, wherein the guide section of the guide element is arranged substantially directly adjacent to the guide rail, so that the guide surface of the guide rail and the guide surface of the guide section are arranged substantially in one plane, and the guide surface of the guide element is thus essentially a direct continuation of the guide surface of the guide rail. According to one embodiment, the guide rail can be a hollow rail. Such a guide rail is particularly rigid and stable.

[0020] 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.

[0021] Preferably, the guide element is designed such that it can be inserted into the guide rail with the fastening section and can thus be connected or joined to the guide rail in a form-fitting manner.

[0022] According to one embodiment, the device is designed or configured such that, in the assembled state of the device, the carrier is fastened with one of its ends to a side wall of the shaft, and the receptacle is arranged on a section of the carrier projecting into the shaft.

[0023] 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.

[0024] 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.

[0025] The support can be designed to bear at least part of the weight of the beam attached to the side wall and comprising the drive motor (and additionally one or more further drive components). In the assembled state of the device, the support can be connected, for example, screwed and / or welded, to the beam on the one hand and to another point in the shaft on the other. It is possible for the beam to have a horizontal longitudinal direction in the assembled state of the device and / or for the support to have a vertical longitudinal direction in the assembled state of the device. A second aspect of the invention relates to a system for supporting multiple drive motors 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 motors.The system comprises a plurality of devices, each device being the device described above and below, and the carrier of each device having a receptacle for attaching one of the drive motors to the carrier.

[0026] 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.

[0027] It is possible that the supports are arranged at the same height in the shaft when the system is assembled.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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 receptacles.

[0032] 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. A fourth aspect of the invention relates to a method for assembling a device for supporting a drive motor of an elevator system, in particular the device described above and below, wherein the elevator system 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 support and a carrier with a receptacle for fastening the drive motor to the carrier; fastening the carrier with one of its ends to the side wall, in particular the same side wall, and / or the ceiling of the shaft, wherein the receptacle is arranged on a portion of the carrier, in particular fastened to the side wall, that projects into the shaft.

[0033] The above steps can be performed in the order given or in a different order than the order given.

[0034] It should be noted that features of the device as described above and below may also be features of the method (and vice versa).

[0035] Embodiments of the invention may be considered to be based on the ideas and findings described below. These embodiments are not to be understood as limiting the scope of the invention. According to one embodiment, the supports of various devices can be attached to the same side wall of the shaft when the system is assembled. In other words, all supports of the system can be attached to the same side wall of the shaft.

[0036] Alternatively, at least one of the supports may be attached to a different side wall than the remaining support(s).

[0037] 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.

[0038] 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 portion of an elevator system according to an embodiment of the invention.

[0039] Fig. 2 shows a drive motor of an elevator system supporting system according to an embodiment of the invention in a perspective view.

[0040] Fig. 3 shows a partial section of the system from Fig. 2.

[0041] Fig. 4 shows a plan view of a partial section of the system from Fig. 3.

[0042] Fig. 5 shows a plan view of a system supporting two drive motors of an elevator installation according to an embodiment of the invention.

[0043] 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.

[0044] 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.

[0045] The device 13 comprises a support 15, a console 17, and a support 20. 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.

[0046] 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.

[0047] The support 20 is on the one hand connected to the section of the

[0048] The support 15 is connected, for example, by screwing and / or welding, to a section of the bracket 17 extending into the shaft 7. Thus, the support 15 is supported on the bracket 17 via the support 20.

[0049] 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 20 and / or the console 17.

[0050] 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.

[0051] 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 20 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.

[0052] In this example, the support 20 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.

[0053] 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.

[0054] As can be seen in Fig. 2, a guide element 69 is attached to the support 15. This guide element 69 is arranged directly above the guide rail 19 and thus represents an extension of the guide rail 19. In the exemplary embodiment shown, the guide element 69 comprises a fastening section 73, to which the guide element 69 is fixed to the support 15 by four screws, for example, as shown in the exemplary embodiment, on a section running parallel to the support 15. Furthermore, the guide element 69 has a guide section with a guide surface 71, wherein the guide surface 71 is designed such that it runs parallel to a guide surface 77 of the guide rail 19. The guide surface 71 of the guide element 69 thus essentially represents a continuation of the guide surface 77 of the guide rail 19.A car brake 67 mounted on the car 11 (see Figure 5), which is guided along the guide rail 19 during travel in the shaft, can thus be guided by the guide element 69 when approaching the top floor, in which the device 13 is mounted, during the last section of the travel (namely when the car brake is at the same height as the support 15). The guide element 69 further has a connecting section 75. In the illustrated embodiment, this connecting section 75 runs perpendicular to both the fastening section and the guide section and serves to connect these two sections. In the illustrated embodiment, the guide element 69 is designed as a one-piece sheet metal part.

[0055] Fig. 3 shows that the fastening section is designed such that, in addition to the section running parallel to the support (fastening surface 73), it also has a section running perpendicular thereto, with which the fastening section can be inserted or is inserted into the guide rail 19. By inserting the fastening section into the guide rail 19, the guide element 69 can be fastened or secured to the system (guide rail 19) with a positive fit. Furthermore, this section helps to position or align the fastening element 69 relative to the guide rail 19.

[0056] In Fig. 4 it can be seen how the fastening element 69 essentially represents an extension of the guide rail 19 along the support 15.

[0057] 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. 5). 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.

[0058] As can be seen in Fig. 5, 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. The supports 15 of various devices 13 can be arranged at the same height in the shaft 7 when the system 35 is assembled. Additionally or alternatively, the consoles 17 of various devices 13 can be arranged at the same height in the shaft 7 when the system 35 is assembled. The cabin 11 can be arranged between the supports 20 or guide rails 19 when the system 35 is assembled.

[0059] 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.
