Description

AREA OF TECHNOLOGY

[0001] The present invention relates to an elevator system, and in particular an elevator system that facilitates the replacement of the motor. STATE OF THE ART

[0002] In elevator systems without a machine room, where the motor is mounted on the guide rail, it may be necessary to replace the motor due to its service life or for other reasons. The new motor is likely to have a different design than the old one, meaning the existing mounting structure on the guide rail will not be compatible with the new motor's mounting structure. Therefore, it may be necessary to replace the guide rail to install the new motor, which is more expensive and complex.

[0003] Therefore, the object of the present invention is to propose an elevator system that improves upon the aforementioned disadvantages of the prior art. DESCRIPTION OF THE INVENTION

[0004] According to one aspect of the present invention, an elevator system is proposed comprising: a guide rail; a cabin configured to move along the guide rail; a motor configured to drive the cabin, the motor being provided with a motor installation hole; the elevator system further comprising an adapter plate arranged between the motor and the guide rail, the adapter plate being attached to the guide rail, and the adapter plate having a first mounting hole aligned with the motor installation hole for attaching the adapter plate to the motor.

[0005] According to this concept, attaching the adapter plate to both the motor and the guide rail ensures that replacing the motor does not require replacing the guide rail, thus reducing the maintenance costs of the elevator system and simplifying the motor replacement process.

[0006] In some embodiments, the adapter plate may have a second mounting hole, and the guide rail may have a guide rail mounting hole, with the second mounting hole being aligned with the guide rail mounting hole to secure the adapter plate to the guide rail.

[0007] In some embodiments, the guide rail extends in a vertical direction, and the motor may have multiple motor installation holes, wherein the motor installation holes include an upper installation hole on the upper part of the motor and a lower installation hole on the lower part of the motor; the adapter plate may have multiple first mounting holes, wherein the first mounting holes include a first upper mounting hole on the upper part of the adapter plate and a first lower mounting hole on the lower part of the adapter plate; the first upper mounting hole is aligned with the upper installation hole and the first lower mounting hole is aligned with the lower installation hole.

[0008] In some embodiments, the guide rail may have multiple guide rail mounting holes, wherein the guide rail mounting holes comprise an upper mounting hole on the upper part of the guide rail and a lower mounting hole on the lower part of the guide rail; the adapter plate may have multiple second mounting holes, wherein the second mounting holes comprise a second upper mounting hole on the upper part of the adapter plate and a second lower mounting hole on the lower part of the adapter plate; the second upper mounting hole is aligned with the upper mounting hole and the second lower mounting hole is aligned with the lower mounting hole.

[0009] In some embodiments, the first lower mounting hole and the second lower mounting hole may overlap.

[0010] In some embodiments, the elevator system may further include a clamping device, wherein the adapter plate is attached to the guide rail via the clamping device, and wherein the clamping device at least partially clamps a part of the guide rail.

[0011] In some embodiments, the clamping device may have a mounting section and a clamping section, wherein the mounting section is attached to the adapter plate and the clamping section is configured to clamp the guide rail.

[0012] In some embodiments, the adapter plate can comprise a main body and a widened section, wherein the widened section is arranged above the main body and has a greater width compared to the main body, and wherein the mounting section is attached to the widened section.

[0013] In some embodiments, the second upper mounting hole may be located in the widened section, with a hole in the adapter plate interacting with the mounting section located outside the second upper mounting hole and the first upper mounting hole located in the main body.

[0014] In some embodiments, the adapter plate may comprise a main body and two extension sections located on either side of the main body, with each of the two extension sections extending in the direction of the guide rail and the guide rail being arranged between the two extension sections.

[0015] According to this concept, the extension sections increase the strength of the adapter plate while preventing excessive displacement of the guide rail in the transverse direction.

DETAILED DESCRIPTION OF THE REVELATION

[0016] To clarify the objectives, solutions, and advantages of the technical concept of the present invention, the technical concept of the embodiments of the present invention is described clearly and completely below with reference to the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have their customary meanings in the field. Identical fastening symbols in the accompanying drawings represent identical components.

[0017] Fig. Figure 1 shows a schematic representation of an elevator system 100 according to a first embodiment of the present invention. The elevator system 100 mainly comprises a guide rail 110, a cabin (not shown), and a motor 120. The guide rail 110 extends, for example, in a vertical direction and serves as a track along which the cabin moves vertically. The cabin moves along the guide rail 110 to transport passengers in the cabin, for example, from the first floor of a building to the tenth floor. The motor 120 is configured to move the cabin along the guide rail 110; for example, the output shaft of the motor 120 can be connected to the cabin via a gear system.

[0018] As in Fig. As shown in Figure 2, the motor 120 is provided with motor installation holes 122 and 124 for attaching it to the guide rail 110. It may be necessary to replace the motor due to the end of its service life or for other reasons. However, during the replacement process, it may happen that the new motor 120 cannot be mounted directly to the guide rail 110 in the same way as the old motor because it is a different model (not shown). For example, the position of the installation holes of the new motor 120 may differ from that of the old motor. If the installation holes of the old motor were aligned with the mounting holes of the guide rail 110, the installation holes of the new motor 120 will no longer be perfectly aligned, resulting in incompatibility between the new motor 120 and the guide rail 110.

[0019] To improve upon the aforementioned problem of incompatibility between the new motor 120 and the guide rail 110, the elevator system 100 proposed in this disclosure further comprises an adapter plate 130 arranged between the motor 120 and the guide rail 110. The adapter plate 130 is attached to both the guide rail 110 and the motor 120, so that the motor 120 is attached to the guide rail 110 via the adapter plate 130.

[0020] Optionally, the adapter plate 130 can include a first upper mounting hole 134-U on its upper part and a first lower mounting hole 134-L on its lower part. The first upper mounting hole 134-U and the first lower mounting hole 134-L are each aligned with the upper installation hole 122 on the upper part of the motor 120 and the lower installation hole 124 on the lower part of the motor 120, respectively. A fastener (e.g., a screw) passes through the first upper mounting hole 134-U and the upper installation hole 122 to secure the upper part of the motor 120 to the adapter plate 130. A fastener (e.g., a screw) passes through the first lower mounting hole 134-L and the lower installation hole 124 to secure the lower part of the motor 120 to the adapter plate 130.

[0021] Optionally, the adapter plate 130 can include a second upper mounting hole 136-U on its upper part and a second lower mounting hole 136-L on its lower part. The second upper mounting hole 136-U and the second lower mounting hole 136-L are each aligned with the upper mounting hole 112 on the upper part of the guide rail 110 and the lower mounting hole 114 on the lower part of the guide rail 110, respectively. A fastener (e.g., a screw) passes through the second upper mounting hole 136-U and the upper mounting hole 112 to secure the upper part of the guide rail 110 to the adapter plate 130. A fastener (e.g., a screw) passes through the second lower mounting hole 136-L and the lower mounting hole 114 to secure the lower part of the guide rail 110 to the adapter plate 130.

[0022] Optionally, the first lower mounting hole 134-L and the second lower mounting hole 136-L can overlap. A fastener passes sequentially through the lower mounting hole 114, the first lower mounting hole 134-L (which is also the second lower mounting hole 136-L), and the lower installation hole 124 to attach the motor 120 to the guide rail 110 via the adapter plate 130. In other words, the hole configured to attach the lower part of the adapter plate 130 to the lower part of the guide rail 110 and the hole configured to attach the lower part of the adapter plate 130 to the lower part of the motor 120 can be identical.Alternatively, the elevator system 100 can also be designed such that the first upper mounting hole and the second upper mounting hole overlap, with a fastening element passing successively through the upper mounting hole 112, the first upper mounting hole (which is also the second upper mounting hole), and the upper installation hole to attach the motor 120 to the guide rail 110 via the adapter plate 130. It is understood that, although described above, dual-purpose holes (for attachment to the guide rail 110 and for attachment to the motor 120) can be provided on the upper or lower part of the adapter plate 130, this disclosure is not limited to such possibilities, and it is also possible that no dual-purpose holes are provided on the upper or lower part of the adapter plate 130.

[0023] It goes without saying that, although Fig. 2 Four first upper mounting holes 134-U, four second upper mounting holes 136-U and eight first lower mounting holes 134-L (which are also second lower mounting holes 136-L) shows that the present disclosure does not intend to limit the number of holes (guide rail mounting holes, first mounting holes, second mounting holes, motor installation holes).

[0024] Fig. 3 to Fig. Figure 5 shows a motor system 200 according to a second embodiment. For the sake of brevity, only the differences between the second and first embodiments are described in detail below, while the similarities between the second and first embodiments are not discussed again. In addition to the method in which fastening elements are guided through the guide rail mounting holes 212, 214 and the second mounting holes 236-U, 236-L, the fastening of the adapter plate 230 to the guide rail 210 can also be achieved by a clamping device 240.It is understood that the present disclosure does not intend to restrict the specific fastening method between the adapter plate 230 and the guide rail 210; the fastening between the adapter plate 230 and the guide rail 210 can be effected by screws, clamping devices or a combination of screws and clamping devices, as well as in any other suitable manner.

[0025] Specifically, the clamping device 240, as shown in Fig. Figure 4 shows a mounting section 242 and a clamping section 244. The mounting section 242 is attached to the adapter plate 230, and the clamping section 244 is configured to clamp the guide rail 210. For example, the mounting section 242 can be attached to the adapter plate 230 via an interacting hole 238, which can also be referred to as the interacting hole 238.

[0026] Furthermore, the adapter plate can be used as described in 230. Fig. Figure 5 shows a main body 231 and a widened section 232. The widened section 232 is located above the main body 231 and is wider than the main body 231. The interaction hole 238 and the second upper mounting holes 236-U are located in the widened section 232. The first upper mounting holes 234-U are located in the main body 231. The interaction hole 238 can be located outside the second upper mounting holes 236-U, so that the fastening section 242 of the clamping device 240 is attached to the outer part of the widened section 232 of the adapter plate 230, which makes it easier for the clamping section 244 of the clamping device 240 to extend inward from the fastening section 242 to clamp the guide rail 210.

[0027] Fig. 6 to Fig.Figure 8 shows a motor system 300 according to a third embodiment. For the sake of brevity, only the differences between the third embodiment and the previous embodiments are described in detail below, while the similarities between the third embodiment and the previous embodiments are not discussed again. The adapter plate 330 can further comprise a main body 331 and two extension sections 333 located on both sides of the main body 331. The two extension sections 333 each extend in the direction of the guide rail 310, and the guide rail 310 is arranged between the two extension sections 333. The extension sections 333 increase the strength of the adapter plate 330 and simultaneously prevent excessive lateral displacement of the guide rail 310.

However, those skilled in the art will understand that various modifications and changes can be made to the specific embodiments mentioned above without departing from the creative idea of ​​the invention, and that the various technical features and structures proposed by this invention can be combined without exceeding the scope of protection of the invention.
