Description

Technical Field

[0001] This disclosure relates to the field of elevator technology, and more specifically, to a damping component for a compensating chain, a compensating chain guiding device, an elevator, and a damping control method for a compensating chain. Background Technology

[0002] In elevator technology, especially in super high-rise elevators with floor heights exceeding 100 meters, the overall system stiffness is generally low, even when the steel wire rope configuration just meets the breaking force requirements, due to the influence of its length and number. When the car stops at the lowest floor and a passenger enters, the weight of a 75kg passenger can, in severe cases, cause a car sinking of nearly 8mm. If the elevator installation quality is good and the steel wire rope traction system, guiding system, and compensation system do not have excessive friction input, the car sinking will cause prolonged oscillations, resulting in passenger discomfort. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, this disclosure proposes a damping component for a compensation chain, a compensation chain guiding device, an elevator, and a damping control method for the compensation chain, which has the advantage of reducing car sway.

[0004] One aspect of this disclosure provides a damping assembly for a compensation chain, including a support member, two opposing damping groups and an electromagnetic group, the two opposing damping groups being movably disposed on the support member; each of the damping groups is provided with an electromagnetic group, wherein when the electromagnetic group is energized, an attractive force is generated between the electromagnetic groups located on the two opposing damping groups, driving the two opposing damping groups to move toward each other to clamp the compensation chain.

[0005] According to the damping assembly of the present disclosure, by energizing the electromagnetic group, an attractive force can be generated between the two opposing electromagnetic groups. The attractive force can drive the two damping groups to move toward each other, thereby clamping the compensation chain. When the car moves up and down, the compensation chain contacts and rubs against the damping group, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0006] In some embodiments, the damping assembly further includes a reset member connected between the two opposing damping groups to drive the two opposing damping groups to move away from each other.

[0007] In some embodiments, each of the damping groups has a first end and a second end, the first ends of the two damping groups are disposed opposite to each other, the second ends of the two damping groups are disposed opposite to each other, a reset member is provided between the two first ends, and a reset member is provided between the two second ends.

[0008] In some embodiments, a first mounting groove is provided at the first end of each damping group, a second mounting groove is provided at the second end of each damping group, the two ends of the reset member between the two first ends are disposed in the first mounting groove, and the two ends of the reset member between the two second ends are disposed in the second mounting groove.

[0009] In some embodiments, one of the electromagnetic groups located on the two opposing damping groups is an energized coil, and the other is an electromagnet.

[0010] In some embodiments, the support member has one of a groove and a rail, and the two opposing damping groups each have the other of a groove and a rail, the groove cooperating with the rail.

[0011] In some embodiments, the support member includes a bracket portion and a support portion, the support portion being disposed on the bracket portion, and the support portion having one of a groove and a rail.

[0012] Another aspect of this disclosure provides a compensation chain guiding device, comprising: a damping assembly, the damping assembly being a damping assembly according to the above description; and a compensation chain guiding assembly, the support member being disposed on the compensation chain guiding assembly.

[0013] According to the compensation chain guide device of the present disclosure, by energizing the electromagnetic group, an attractive force can be generated between the two opposing electromagnetic groups. The attractive force can drive the two damping groups to move toward each other, thereby clamping the compensation chain. When the car moves up and down, the compensation chain contacts and rubs against the damping groups, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0014] Another aspect of this disclosure provides an elevator, comprising: a compensating chain; and a compensating chain guide device, the compensating chain guide device being as described above, wherein the compensating chain passes through the compensating chain guide device to provide guidance and / or damping for the compensating chain.

[0015] According to the elevator of the present disclosure, by energizing the electromagnetic group, an attractive force can be generated between the two opposing electromagnetic groups. The attractive force can drive the two damping groups to move toward each other, thereby clamping the compensation chain. When the car moves up and down, the compensation chain contacts and rubs against the damping group, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0016] Another aspect of this disclosure provides a damping control method for a compensation chain, comprising: determining whether the floor where the car stops is a preset floor and whether the car door is in an open state; if the floor where the car stops is a preset floor and the car door is in an open state, determining the direction of movement of the car; when the car moves upward, controlling the energizing current of the electromagnetic group to be a first current, such that the attraction force generated between the electromagnetic groups is greater than the elastic force of the reset member, the attraction force driving the two opposing damping groups to move toward each other to clamp the compensation chain, wherein the electromagnetic group and the reset member are the electromagnetic group and reset member as described in claim 2; and when the car moves downward, controlling the energizing current of the electromagnetic group to be a second current, such that the attraction force generated between the electromagnetic groups is less than the elastic force of the reset member, the elastic force driving the two opposing damping groups to move away from each other to relax the compensation chain.

[0017] According to the damping control method for a compensation chain according to the embodiments of this disclosure, by passing different magnitudes of current through the electromagnetic groups, the magnitude of the attractive force generated between two opposing electromagnetic groups can be controlled, thereby controlling the direction of movement of the opposing damping groups, thereby achieving the clamping or loosening of the compensation chain.

[0032] The embodiments of this disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this disclosure. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this disclosure. Additionally, the various embodiments and technical features provided below can be combined with each other in any manner.

[0033] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. Furthermore, the terms "comprising," "including," etc., as used herein indicate the presence of said features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components. All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0034] The following is for reference. Figures 1 to 7 This disclosure describes a damping assembly 10 for a compensation chain, a compensation chain guide device 200, an elevator 1000, and a damping control method for a compensation chain, according to embodiments of the present disclosure.

[0035] like Figures 1-4 As shown, the damping assembly 10 for a compensation chain according to an embodiment of the present disclosure includes a support member 1, two opposing damping groups 2, and an electromagnetic group 3.

[0036] Specifically, combined Figures 1-3Two opposing damping groups 2 are movably mounted on the support member 1; each damping group 2 is provided with an electromagnetic group 3, wherein when the electromagnetic group 3 is energized, an attraction is generated between the electromagnetic groups 3 located on the two opposing damping groups 2, driving the two opposing damping groups 2 to move toward each other to clamp the compensation chain 100.

[0037] Understandably, when the electromagnetic assembly 3 is energized, an attractive force is generated between the two opposing electromagnetic assemblies 3. The greater the current flowing through the electromagnetic assemblies 3, the stronger the attractive force between them. Since the two electromagnetic assemblies 3 are each located within a damping assembly 2, the attractive force can drive the two damping assemblies 2 to move closer to each other, thus clamping the compensation chain 100. This allows for quantitative adjustment of the frictional force on the compensation chain 100, thereby providing viscous damping for the system.

[0038] Especially during the elevator's shaking caused by passengers entering and exiting at the bottom floor, increasing the system damping can quickly reduce the elevator's oscillation time, decrease the car's vibration amplitude, and reduce passenger discomfort. For example... Figure 4 The diagram shows a comparison of vibration attenuation curves before and after the installation of the damping assembly 10 disclosed herein in the elevator. During the elevator car's up-and-down shaking, the response amplitude and response time decrease due to the increase in system damping. Here, a damping group 2 can be a single damping element or a combination of multiple parallel damping elements.

[0039] Especially in elevators in super high-rise buildings with a floor height exceeding 100 meters, the overall system stiffness is generally low, even when the steel wire rope configuration just meets the breaking force requirements, due to the influence of length and number of ropes. When the car stops at the lowest floor and a passenger enters, the weight of a 75kg passenger can cause a car sinking of nearly 8mm in severe cases. If the elevator installation quality is good and the steel wire rope traction system, guiding system, and compensation system do not have excessive friction input, the car sinking will cause prolonged oscillation, resulting in passenger discomfort.

[0040] According to the damping assembly 10 of the present disclosure, by energizing the electromagnetic group 3, an attractive force can be generated between the two opposing electromagnetic groups 3. The attractive force can drive the two damping groups 2 to move toward each other, thereby clamping the compensation chain 100. When the car moves up and down, the compensation chain 100 contacts and rubs against the damping group 2, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0041] According to some embodiments of this disclosure, such as Figures 1-3As shown, the damping assembly 10 also includes a reset member 4, which is connected between two opposing damping groups 2 to drive the two opposing damping groups 2 to move away from each other. Therefore, when damping is not required on the compensation chain 100, the current supplied to the electromagnetic group 3 can be reduced, making the attractive force between the two electromagnetic groups 3 less than the restoring force of the reset member 4. The restoring force can drive the two opposing damping groups 2 to move away from each other, thereby relaxing the compensation chain 100. The reset member 4 facilitates the reset of the two opposing damping groups 2.

[0042] In some embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, each damping group 2 has a first end 21 and a second end 22. The first ends 21 of the two damping groups 2 are arranged opposite each other, and the second ends 22 of the two damping groups 2 are arranged opposite each other. A reset member 4 is provided between the two first ends 21 and the two second ends 22. Thus, the reset member 4 can be set at both ends of the damping group 2 that are perpendicular to the direction of movement of the damping group 2, thereby making the movement of the damping group 2 more balanced and preventing jamming during movement.

[0043] Furthermore, combined Figure 1 and Figure 2 Each damping assembly 2 has a first mounting groove 211 at its first end 21 and a second mounting groove 221 at its second end 22. The reset member 4 between the two first ends 21 has both ends located in the first mounting groove 211, and the reset member 4 between the two second ends 22 has both ends located in the second mounting groove 221. This facilitates the placement of the reset member 4 at both ends of the damping assembly 2 perpendicular to its direction of movement.

[0044] In some embodiments of this disclosure, one of the electromagnetic groups 3 located on two opposing damping groups 2 is an energized coil, and the other is an electromagnet. When the energized coil is energized, the energized coil and the electromagnet attract each other, thereby facilitating the energization of the electromagnetic groups 3 to generate an attractive force between the two opposing electromagnetic groups 3. Each electromagnetic group 3 can be a single energized coil or an electromagnet, or it can be multiple energized coils or electromagnets; the number of electromagnetic components included in each electromagnetic group 3 is not limited.

[0045] According to some embodiments of this disclosure, such as Figures 1-3As shown, the support member 1 has one of a groove 121 and a slide rail 23, and each of the two opposing damping groups 2 has the other of a groove 121 and a slide rail 23, with the groove 121 engaging with the slide rail 23. It can be understood that when the support member 1 has a groove 121, both opposing damping groups 2 have slide rails 23; and when the support member 1 has a slide rail 23, both opposing damping groups 2 have grooves 121. This facilitates the sliding of the damping groups 2 on the support member 1, allowing the two opposing damping groups 2 to move towards each other or away from each other.

[0046] In some embodiments of this disclosure, such as Figure 3 As shown, the support member 1 includes a bracket portion 11 and a support portion 12. The support portion 12 is disposed on the bracket portion 11 and has one of a slide groove 121 and a slide rail 23. The bracket portion 11 can support and fix the support portion 12, and the support portion 12 can facilitate the provision of a motion environment for the damping assembly 2. Specifically, the support portion 12 can be conveniently provided with one of the slide groove 121 and the slide rail 23.

[0047] like Figure 5 As shown, the compensation chain guide device 200 according to an embodiment of the present disclosure includes a damping component 10 and a compensation chain guide component 20, wherein the damping component 10 is the damping component 10 as described above; and the support member 1 is disposed on the compensation chain guide component 20.

[0048] According to the compensation chain guide device 200 of the present disclosure, by energizing the electromagnetic group 3, an attractive force can be generated between the two opposing electromagnetic groups 3. The attractive force can drive the two damping groups 2 to move toward each other, thereby clamping the compensation chain 100. When the car moves up and down, the compensation chain 100 contacts and rubs against the damping group 2, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0049] like Figure 6 As shown, the elevator 1000 according to an embodiment of the present disclosure includes a compensation chain 100 and a compensation chain guide device 200. The compensation chain guide device 200 is as described above. The compensation chain 100 passes through the compensation chain guide device 200 so that the compensation chain guide device 200 provides guidance and / or damping for the compensation chain 100.

[0050] According to the elevator 1000 of this disclosure embodiment, by energizing the electromagnetic group 3, an attractive force can be generated between the two opposing electromagnetic groups 3. The attractive force can drive the two damping groups 2 to move toward each other, thereby clamping the compensation chain 100. When the car moves up and down, the compensation chain 100 contacts and rubs against the damping group 2, absorbing the energy of the car's up and down swaying, reducing the amplitude and duration of the car's swaying, and reducing passenger discomfort.

[0051] like Figure 7 As shown, the damping control method for the compensation chain according to an embodiment of this disclosure includes: determining whether the floor where the car stops is a preset floor and whether the car door is in an open state; if the floor where the car stops is a preset floor and the car door is in an open state, determining the direction of movement of the car; when the car moves upward, controlling the energizing current of the electromagnetic group 3 to be a first current, so that the attraction force generated between the electromagnetic groups 3 is greater than the elastic force of the reset member 4, and the attraction force drives the two oppositely arranged damping groups 2 to move toward each other to clamp the compensation chain 100, wherein the electromagnetic group 3 and the reset member 4 are as described above; and when the car moves downward, controlling the energizing current of the electromagnetic group 3 to be a second current, so that the attraction force generated between the electromagnetic groups 3 is less than the elastic force of the reset member 4, and the elastic force drives the two oppositely arranged damping groups 2 to move away from each other to relax the compensation chain 100.

[0052] Understandably, in high-rise elevators (1000) with a floor height exceeding 100 meters, the overall system stiffness is generally low due to the influence of length and number of steel wire ropes, even if the breaking force requirement is just met. Therefore, when the car stops at a lower floor, the car is prone to vertical vibration when a customer enters. Based on this, applying damping to the compensation chain 100 when the car stops at a lower floor maximizes energy efficiency while still ensuring customer comfort. Specifically, floors can be preset so that applying damping to the compensation chain 100 only occurs when the car stops at the preset floor and the car door is open, thus saving control energy. When the car stops at a floor other than the preset floor and / or the car door is not open, the control electromagnetic group 3 is de-energized.

[0053] Furthermore, considering the motion characteristics of the compensation chain 100, if the compensation chain 100 cannot automatically slide down and reset under the action of the guide wheel in the stopping area but instead moves upward and becomes tensioned, the magnitude of the current can be controlled according to the direction of the car's movement. Specifically, when the car moves upward, the energizing current of the control electromagnetic group 3 is the first current, so that the attraction force generated between the electromagnetic groups 3 is greater than the elastic force of the reset member 4. The attraction force drives the damping groups 2, which are arranged opposite to each other, to move towards each other to clamp the compensation chain 100. When the car moves downward, the energizing current of the control electromagnetic group 3 is the second current, so that the attraction force generated between the electromagnetic groups 3 is less than the elastic force of the reset member 4. The elastic force drives the damping groups 2, which are arranged opposite to each other, to move away from each other to relax the compensation chain 100.

[0054] According to the damping control method for the compensation chain according to the embodiments of this disclosure, by passing different magnitudes of current through the electromagnetic group 3, the magnitude of the attraction force generated between the two opposing electromagnetic groups 3 can be controlled, thereby controlling the moving direction of the opposing damping group 2, thereby achieving the clamping or loosening of the compensation chain 100.
