Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a distributed steel belt traction machine. Background Technology

[0002] As an indispensable vertical transportation tool in modern buildings, elevators are receiving increasing attention for their safety and aesthetics. In recent years, with the innovation of architectural design concepts, glass-shaft elevators, due to their transparent, bright, stylish, and beautiful characteristics, have gradually become the preferred choice for high-end buildings. However, while glass-shaft elevators bring visual enjoyment, they also expose the technical defects of traditional traction systems in terms of exposed steel belts.

[0003] Traditional elevator traction systems typically use steel wire ropes or steel belts as the traction medium. Steel belts, due to their good flexibility and long service life, are widely used in machine-room-less elevators and elevators with small machine rooms. However, in glass shaft conditions, the steel belts of traditional traction systems are exposed inside the shaft as the car moves between different floors, compromising the overall transparency and aesthetics of the glass shaft. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a distributed steel strip traction machine that is simple in structure, highly adaptable, and aesthetically pleasing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] This application provides a distributed steel belt traction machine, comprising:

[0007] Base;

[0008] A central pivot is rotatably mounted on the base.

[0009] The base is fixedly provided with a stator coaxial with the central rotating shaft, and the central rotating shaft is fixedly provided with a rotor located at the corresponding position of the stator;

[0010] The two ends of the central rotating shaft protrude to the outside of the base, and a first pulley is fixed at one end and a second pulley is fixed at the other end.

[0011] Further specifying, in the aforementioned distributed steel strip traction machine, the two ends of the central rotating shaft are rotatably connected to the base via a first bearing and a second bearing, respectively.

[0012] Furthermore, in the aforementioned distributed steel strip traction machine, the base is also fixedly equipped with a sensing unit for monitoring the rotation parameters of the central rotating shaft.

[0013] Further specifying, in the above-mentioned distributed steel belt traction machine, the sensing unit includes an encoder base fixedly disposed at one end of the central rotating shaft, and an encoder sensing body fixedly disposed on the base and corresponding to the position of the encoder base;

[0014] The encoder base and the encoder sensing body can cooperate with each other to monitor the rotation parameters of the central shaft.

[0015] Further specifying, in the aforementioned distributed steel belt traction machine, a brake is fixedly provided between the base and the central rotating shaft.

[0016] Further specifying, in the above-mentioned distributed steel belt traction machine, the brake includes a brake disc fixedly mounted on the central rotating shaft and a brake pad fixedly connected to the base via an electromagnetic control unit;

[0017] The electromagnetic control unit can adjust the relative position between the brake pads and the brake disc to achieve friction braking between the brake pads and the brake disc.

[0018] Further specifying, in the above-mentioned distributed steel strip traction machine, the base includes a first base body and a second base body, and the central rotating shaft includes a first shaft portion rotatably disposed on the second base body and a second shaft portion rotatably disposed on the first base body;

[0019] Wherein, the first shaft portion is sleeved on the second shaft portion at one end near the second shaft portion and is splinedly connected to the second shaft portion;

[0020] Alternatively, the second shaft portion may be sleeved on the first shaft portion at one end near the first shaft portion and splinedly connected to the first shaft portion.

[0021] Further specifying, in the above-mentioned distributed steel strip traction machine, the second base body is sleeved on the first base body at one end near the first base body and is slidably connected to the first base body;

[0022] Alternatively, the first seat body may be fitted onto the second seat body at one end near the second seat body and slidably connected to the second seat body.

[0023] Further specifying, in the above-mentioned distributed steel strip traction machine, the second base body is provided with a plurality of adjustment holes arranged in a linear array along the central axis, and the first base body is provided with mounting holes.

[0024] It also includes fastening bolts, which can be threadedly connected to the mounting holes on the first body through the adjustment holes on the second body.

[0025] Further specifying, in the aforementioned distributed steel strip traction machine, a support portion is fixedly provided at the bottom of the base, and a fixing hole is provided through the support portion.

[0026] This utility model has at least the following beneficial effects:

[0027] 1. The first and second pulleys are set at both ends of the central shaft, corresponding to the position of the elevator car door frame. This makes all the longitudinal components of the steel belt hidden in the projection area of ​​the door frame, solving the visual discontinuity problem caused by the exposed steel belt in the glass shaft of the traditional traction system. It maintains the overall transparency and aesthetics of the glass shaft, meets the high requirements of modern buildings for elevator aesthetics, and has little impact on the thickness of the door frame, ensuring the lightweight design of the shaft.

[0028] 2. Since the first pulley and the second pulley are respectively located at both ends of the central shaft, by setting bearing structures connected to the base at both ends of the central shaft, the overall load of the central shaft can be balanced, the support capacity of the central shaft can be improved, and the rotational stability of the central shaft can be guaranteed.

[0029] 3. Because the central shaft adopts a split design, the spline connection does not affect the torque transmission between the two parts. At the same time, it realizes the axial relative position adjustment between the first shaft and the second shaft, thereby realizing the distance adjustment between the first pulley and the second pulley. This allows it to adapt to the door frame position of different elevator models, ensuring the positioning between the traction machine steel belt and the door frame, and further improving the overall applicability and practicality of the device.

Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0041] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0042] The distributed steel strip traction machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] like Figures 1 to 5 As shown, this application embodiment provides a distributed steel strip traction machine, including a base 100 and a central rotating shaft 200 rotatably disposed on the base 100. A stator 610 coaxial with the central rotating shaft 200 is fixedly disposed on the base 100, and a rotor 620 located at the corresponding position of the stator 610 is fixedly disposed on the central rotating shaft 200.

[0044] The central rotating shaft 200 has two ends that protrude to the outside of the base 100, and one end is fixedly provided with a first pulley 310 and the other end is fixedly provided with a second pulley 320.

[0045] It is understandable that the stator 610 and rotor 620 cooperate to drive the rotation of the central shaft 200, the brake 400 is used to brake the rotation of the central shaft 200 relative to the base 100, the first pulley 310 and the second pulley 320 are used to wind the steel belt, the steel belt is connected to the elevator car, and is used for the lifting drive of the elevator car.

[0046] In this embodiment, a distributed steel belt traction machine as described above is used, with the first pulley 310 and the second pulley 320 positioned at both ends of the central rotating shaft 200, corresponding to the position of the elevator car door frame. This allows all longitudinal components of the steel belt to be hidden within the projection area of ​​the door frame, solving the visual discontinuity problem caused by the exposed steel belt in the glass shaft of traditional traction systems. This maintains the overall transparency and aesthetics of the glass shaft, meeting the high aesthetic requirements of modern buildings for elevators. At the same time, it has minimal impact on the thickness of the door frame, ensuring the lightweight design of the shaft.

[0047] In a preferred embodiment, such as Figure 3 As shown, the two ends of the central rotating shaft 200 are rotatably connected to the base 100 through the first bearing 710 and the second bearing 720, respectively.

[0048] It is understandable that, since the first pulley 310 and the second pulley 320 are respectively set at both ends of the central shaft 200, by setting bearing structures connected to the base 100 at both ends of the central shaft 200, the overall load of the central shaft 200 can be balanced, the support capacity of the central shaft 200 can be improved, and the rotational stability of the central shaft 200 can be guaranteed.

[0049] In a preferred embodiment, such as Figures 1 to 3 As shown, a sensing unit 500 for monitoring the rotation parameters of the central rotating shaft 200 is also fixed on the base 100.

[0050] Understandably, the rotational parameters acquired by the sensing unit 500 include, but are not limited to, position parameters (by detecting the rotation angle and number of revolutions of the central shaft 200, the real-time position of the elevator car is calculated), speed parameters (by measuring the rotational speed of the central shaft 200 in real time, thereby monitoring the elevator's operating speed and ensuring that it conforms to the set operating curve), direction parameters (by detecting the rotational direction of the motor, thereby determining whether the elevator is going up or down, ensuring the accuracy of the operating direction), acceleration parameters (by indirectly calculating the elevator's acceleration through the rate of change of the pulse signal, used to monitor the smoothness of the elevator's start and stop), and distance parameters (by recording the number of revolutions and angles, calculating the distance the elevator car moves in the shaft, used for floor positioning and operation control), etc.

[0051] In a preferred embodiment, such as Figures 1 to 3 , Figure 5 As shown, the sensing unit 500 includes an encoder base 510 fixedly disposed at the end of the central rotating shaft 200, and an encoder sensing body 520 fixedly disposed on the base 100 and corresponding to the position of the encoder base 510.

[0052] The encoder base 510 and the encoder sensing body 520 can cooperate with each other to monitor the rotation parameters of the central rotating shaft 200.

[0053] In a preferred embodiment, such as Figures 1 to 3 As shown, a brake 400 is fixedly installed between the base 100 and the central rotating shaft 200.

[0054] In a preferred embodiment, the brake 400 includes a brake disc fixedly mounted on the central rotating shaft 200 and a brake pad fixedly connected to the base 100 via an electromagnetic control unit.

[0055] The electromagnetic control unit can adjust the relative position between the brake pads and the brake disc to achieve friction braking between the brake pads and the brake disc.

[0056] In a preferred embodiment, such as Figures 1 to 3 As shown, a support part 110 is fixedly provided at the bottom of the base 100, and a fixing hole 111 is provided through the support part 110.

[0057] It is understandable that the support part 110 is used to support the base 100 as a whole, and the base 100 can be fixedly mounted on the installation platform by bolts through the fixing holes 111 on the support part 110, thereby realizing the overall fixation of the traction machine.

[0058] In a preferred embodiment, such as Figure 4As shown, the base 100 includes a first base body 101 and a second base body 102, and the central rotating shaft 200 includes a first shaft portion 210 rotatably disposed on the second base body 102 and a second shaft portion 220 rotatably disposed on the first base body 101.

[0059] Wherein, the first shaft portion 210 is sleeved on the second shaft portion 220 at one end near the second shaft portion 220 and is splinedly connected to the second shaft portion 220, or the second shaft portion 220 is sleeved on the first shaft portion 210 at one end near the first shaft portion 210 and is splinedly connected to the first shaft portion 210.

[0060] In this embodiment, a distributed steel belt traction machine is adopted. Since the central rotating shaft 200 adopts a split design, the spline connection does not affect the torque transmission between the two. At the same time, the axial relative position adjustment between the first shaft 210 and the second shaft 220 is realized, thereby realizing the distance adjustment between the first pulley 310 and the second pulley 320. This allows it to adapt to the door frame position of different elevator models, ensuring the positioning between the traction machine steel belt and the door frame, and further improving the overall applicability and practicality of the device.

[0061] In a preferred embodiment, such as Figure 4 As shown, the second seat 102 is sleeved on the first seat 101 at one end near the first seat 101 and is slidably connected to the first seat 101, or the first seat 101 is sleeved on the second seat 102 at one end near the second seat 102 and is slidably connected to the second seat 102.

[0062] It is understandable that when the first base 101 and the second base 102 are fixedly mounted on the mounting platform based on the relative positions of the first shaft portion 210 and the second shaft portion 220, the integration of the base 100 and the structural support strength can be improved because the first base 101 and the second base 102 adopt a sleeve structure.

[0063] In a preferred embodiment, such as Figure 4 As shown, the second base 102 is provided with a plurality of adjustment holes 103 arranged in a linear array along the central rotation axis 200, and the first base 101 is provided with a mounting hole 104.

[0064] It also includes a fastening bolt 105, which can be threadedly connected to the mounting hole 104 on the first seat 101 through the adjustment hole 103 on the second seat 102.

[0065] It is understood that the fixed connection between the first seat 101 and the second seat 102 is not limited to the one described above. For example, the adjustment holes 103 can be arranged linearly in an array along the central rotating shaft 200 on the first seat 101, and the mounting holes 104 can be arranged on the second seat 102. In this case, the fixing between the first seat 101 and the second seat 102 can also be achieved by the fastening bolts 105 between the adjustment holes 103 and the mounting holes 104. As long as the fixed connection between the first seat 101 and the second seat 102 can be satisfied after the relative positions of the first shaft portion 210 and the second shaft portion 220 are adjusted, it will not be elaborated here.

[0066] like Figures 1 to 3 , Figures 5 to 8 As shown in the embodiment of this application, an encoder mounting structure for a traction machine is also provided, which is applicable to the distributed steel belt traction machine in the above embodiment. It includes a base 100 and a central rotating shaft 200 rotatably mounted on the base 100. An encoder seat 510 is fixedly mounted at the end of the central rotating shaft 200. A support plate 560 is fixedly mounted on the base 100 at a position corresponding to the encoder seat 510. An encoder sensing body 520 that can cooperate with the encoder seat 510 is provided on the side of the support plate 560 away from the base 100.

[0067] The support plate 560 is located on the side of the encoder base 510 away from the base 100 and has a clearance hole 563 through it. The encoder sensing body 520 is fixedly provided with a mounting ear 521.

[0068] The encoder sensing body 520 can be detachably connected to the end face of the support plate 560 away from the base 100 in a first angle state via the mounting ear 521. The encoder sensing body 520 and the mounting ear 521 can pass through the relief hole 563 axially along the central rotating shaft 200 in a second angle state.

[0069] The second angle state is specifically set so that the encoder sensing body 520 rotates a predetermined angle in the first angle state, and the predetermined angle is less than 360°.

[0070] Understandably, during encoder installation, the encoder housing 510 is first fixed to the end of the central rotating shaft 200, and then the support plate 560 is fixed to the base 100, as follows: Figure 7 As shown, the encoder sensing body 520 is finally mounted on the end face of the support plate 560 away from the base 100 at the first angle. At this time, the encoder base 510 and the encoder sensing body 520 are in a mating state. When disassembling the encoder, first disconnect the connection between the support plate 560 and the base 100, and then disconnect the connection between the encoder sensing body 520 and the support plate 560, as shown. Figure 8As shown, when the encoder sensing body 520 is rotated to the second angle state, the support plate 560 can move axially away from the base 100 along the central rotating shaft 200. The encoder sensing body 520 and the mounting ear 521 can pass through the relief hole 563, so as not to interfere with the disassembly of the support plate 560. After the support plate 560 is disassembled, the fixed connection between the encoder base 510 and the central rotating shaft 200 is released. At this time, the encoder base 510 and the encoder sensing body 520 can be disassembled as a whole.

[0071] In this embodiment, the encoder mounting structure for a traction machine described above is adopted. The encoder sensing body 520 is supported by the support plate 560. Through the matching design of the mounting ear 521 and the clearance hole 563, the encoder sensing body 520 can be fixed on the support plate 560 in the initial state, and can pass through the support plate 560 after rotating a certain angle to achieve quick disassembly of the support plate 560. While realizing the overall disassembly of the encoder, the axial space occupied by the base 100 is small, which optimizes the space utilization inside the glass shaft, solves the problem of difficult disassembly and assembly of traditional encoder mounting structures in narrow shafts, and improves maintenance efficiency.

[0072] In a preferred embodiment, such as Figure 5 , Figure 7 , Figure 8 As shown, two mounting ears 521 are fixedly provided on the encoder sensing body 520, and the two mounting ears 521 are symmetrically arranged about the central axis of the central rotating shaft 200.

[0073] Among them, the predetermined angle is less than 180°.

[0074] In a preferred embodiment, such as Figure 5 , Figure 7 , Figure 8 As shown, the clearance hole 563 is specifically set to be elliptical.

[0075] Specifically, the first angle state is set so that the two mounting ears 521 are located at the short axis position of the relief hole 563, and the second angle state is set so that the two mounting ears 521 are located at the long axis position of the relief hole 563.

[0076] Understandably, at the short axis position of the clearance hole 563, the distance between the two mounting ears 521 is greater than the short axis length of the clearance hole 563, thereby enabling a detachable connection between the mounting ears 521 and the support plate 560; at the long axis position of the clearance hole 563, the distance between the two mounting ears 521 is less than the long axis length of the clearance hole 563, thereby ensuring that the encoder sensing body 520 and the mounting ears 521 can pass through the clearance hole 563.

[0077] In a preferred embodiment, such as Figure 5As shown, the encoder housing 510 has a through first connection hole 511, and the end of the central rotating shaft 200 has a second connection hole 540 corresponding to the position of the first connection hole 511.

[0078] It also includes a positioning bolt 550, which is threadedly connected to the second connecting hole 540 on the central rotating shaft 200 through the first connecting hole 511 on the encoder housing 510.

[0079] It is understandable that the mounting method of the encoder housing 510 on the central rotating shaft 200 is not limited to the one mentioned above. For example, a snap-fit ​​structure can also be set between the two, but the connection strength between the central rotating shaft 200 and the encoder housing 510 in the rotating state must be guaranteed, which will not be elaborated here.

[0080] In a preferred embodiment, such as Figure 5 As shown, multiple second connecting holes 540 are provided on the central rotating shaft 200, and the multiple second connecting holes 540 are arranged in a ring array about the central axis of the central rotating shaft 200.

[0081] The encoder housing 510 has multiple first connection holes 511, and the multiple first connection holes 511 correspond to the multiple second connection holes 540 respectively.

[0082] In a preferred embodiment, such as Figure 5 , Figure 7 , Figure 8 As shown, a plurality of positioning posts 530 are fixedly provided on the end face of the base 100 near the encoder body 510, and the plurality of positioning posts 530 are arranged in a ring array about the central axis of the central rotating shaft 200.

[0083] The support plate 560 is provided with multiple positioning guide holes 561 corresponding to the positions of the positioning posts 530, and the positioning posts 530 are provided with stepped portions.

[0084] In the installation state of the support plate 560, the positioning post 530 passes through the corresponding positioning guide hole 561, the end face of the support plate 560 near the base 100 abuts against the stepped part on the positioning post 530, and the end of the positioning post 530 away from the base 100 is threadedly connected to a locking nut 570 that abuts against the end face of the support plate 560 away from the base 100.

[0085] It is understood that the mounting form of the support plate 560 on the base 100 is not limited to the one described above. For example, a protrusion can be provided on the base 100, and the support plate 560 can be set to abut against the protrusion and fixedly connected to the base 100 by bolts. As long as the relative position between the support plate 560 and the base 100 can be fixed, it will not be elaborated here.

[0086] In a preferred embodiment, such as Figures 1 to 3 , Figure 5 As shown, a pulley for winding the steel strip is fixed on the central rotating shaft 200.

[0087] The pulley is located on the side of the base 100 near the support plate 560, and the encoder housing 510 is located on the side of the pulley away from the base 100.

[0088] In a preferred embodiment, such as Figure 5 , Figure 7 , Figure 8 As shown, three positioning posts 530 are fixedly provided on the base 100, and three positioning guide holes 561 are provided on the support plate 560, corresponding to the positions of the three positioning posts 530 respectively.

[0089] It is understandable that the number of positioning posts 530 is not limited to the one mentioned above. Since the pulley is located between the base 100 and the support plate 560, and a steel belt is wound on the pulley, multiple positioning posts 530 need to provide clearance for both ends of the steel belt. In order to ensure the clearance of the steel belt, the number of positioning posts 530 should not be too large, and they should not interfere with the steel belt. This will not be elaborated here.

[0090] In a preferred embodiment, such as Figures 5 to 8 As shown, the support plate 560 has two third connecting holes 562 that are symmetrical about and pass through the central axis of the central rotating shaft 200.

[0091] The two mounting ears 521 are respectively provided with limiting holes 522. When the encoder sensing body 520 is in the first angle state, the two limiting holes 522 correspond to the positions of the two third connecting holes 562 respectively, and the mounting ears 521 and the support plate 560 can be fixedly connected by bolts.

[0092] It is understood that the detachable connection between the mounting ear 521 and the support plate 560 is not limited to the one mentioned above. For example, a stud can be provided on the support plate 560. After the stud on the support plate 560 passes through the limiting hole 522 on the mounting ear 521, a nut is provided on the side of the mounting ear 521 away from the support plate 560 that is threaded to the stud. In this way, the encoder sensing body 520 can also be fixed on the support plate 560. This will not be elaborated here.

[0093] In a preferred embodiment, such as Figures 6 to 8 As shown, the limiting hole 522 is specifically designed as a waist-shaped hole.

[0094] The center of the waist-shaped hole is located on the central axis of the central rotating shaft 200.

[0095] It is understandable that by setting the limiting hole 522 as an oblong hole, when the mounting ear 521 is connected to the support plate 560 by bolts, a certain angular deviation is allowed between the support plate 560 and the encoder sensing body 520, which facilitates the installation of the encoder sensing body 520 on the support plate 560 and improves the overall installation efficiency of the encoder.

[0096] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0097] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
