Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to a translation drive device, a translation track changing mechanism, and a circulating elevator translation track changing system. Background Technology

[0002] In modern society and economic activities, elevators have become an indispensable vertical transportation tool for carrying people or goods. With social development and the advancement of engineering technology, elevator technology is also developing rapidly to meet the transportation needs of high-rise buildings. However, because traditional elevators occupy one shaft per car, the transportation efficiency of elevators decreases as building height increases. In some super high-rise buildings, it is necessary to install dozens or even hundreds of elevators to meet transportation needs. Elevators occupy an increasingly large area of ​​high-rise buildings, thereby reducing the usable area of ​​the building and hindering cost savings.

[0003] Multi-car circulating elevators can solve the following problems in high-rise buildings: if the number of traditional elevators is too small, it will lead to insufficient carrying capacity; if the number of traditional elevators is too large, it will occupy a large building horizontal area, thus affecting the space utilization rate of the building.

[0004] However, existing multi-car circulating elevators have issues with the smoothness and comfort of the car translation and track changing process, which need to be improved. Summary of the Invention

[0025] Furthermore, the directional terms mentioned in the embodiments of this application, such as [up], [down], [front], [back], [left], [right], [inner], [outer], [side], etc., are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding the embodiments of this application, and not for limiting the embodiments of this application. In the various drawings, structurally similar units are represented by the same reference numerals. For clarity, the various parts in the drawings are not drawn to scale. In addition, some related parts may not be shown in the drawings.

[0026] The following detailed description is based on specific embodiments. It should be noted that the embodiments of this application can be presented in various forms, and some examples will be described below.

[0027] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the circulating elevator translation and track changing system provided in the embodiments of this application. Figure 2 This is a schematic diagram of the main structure of the circulating elevator translation and track changing system provided in an embodiment of this application. Figure 1 and Figure 2 As shown, the circulating elevator translational track-changing system includes a car 2 and any of the translational drive devices 10 provided in this application embodiment. The translational drive device 10 is configured to translate the car 2 in the circulating elevator translational track-changing system. Specifically, the circulating elevator translational track-changing system may also include an elevator vertical shaft (not shown in the figure). In this circulating elevator translational track-changing system, when the car 2 is inside the elevator vertical shaft, it can be raised and lowered by the traction of the traction rope inside the elevator vertical shaft and move to the highest or lowest floor. The translational drive device 10 may be specifically configured to drive the car 2 to move in the horizontal direction (e.g., the X direction in the figure) after the car 2 moves to the highest or lowest floor, so as to realize the translational track-changing of the car 2.

[0028] In this embodiment, as Figures 3 to 7As shown, the aforementioned translation drive device 10 may include a base 11, a frame 12, a drive unit, and an adjustment unit. The frame 12 is mounted on the base 11 and is slidable relative to the base 11 in a horizontal direction (e.g., the X direction in the figure). The drive unit is configured to drive the frame 12 to slide horizontally relative to the base 11 and includes a drive motor 14, a gear 15, and a rack 16. The rack 16 is fixedly connected to the base 11, the gear 15 is meshed with the rack 16, and the drive motor 14 is connected to the gear 15 and configured to drive the gear 15 to rotate, thereby moving the frame 12 along the length of the rack 16, thus enabling the frame 12 to slide horizontally relative to the base 11. The adjustment unit is configured to adjust the meshing clearance between gear 15 and rack 16 in the drive unit. When it is necessary to adjust the meshing clearance between gear 15 and rack 16 during car operation, the adjustment unit can adjust the meshing clearance between gear 15 and rack 16 to ensure that the meshing clearance between gear 15 and rack 16 is stable and reliable, ensuring the smoothness of the translational movement of car 2, reducing the vibration generated by mechanical transmission, and improving car comfort.

[0029] Specifically, the frame 12 can be mounted on top of the base 11, the length direction of the rack 16 is parallel to the sliding direction of the frame 11, and the gear 15 can be located below the rack 16 and mesh with the rack 16.

[0030] In practical applications, such as Figure 1 and Figure 2 As shown, the aforementioned circulating elevator translational track-changing system may further include a car lifting device 20. The car lifting device 20 and the translational drive device 10 together constitute a translational track-changing mechanism for translating and changing the track of the car 2. The translational drive mechanism can drive the car lifting device 20 to move in the horizontal direction (e.g., the X direction in the attached figure). Furthermore, in the aforementioned circulating elevator translational track-changing system, the car lifting device 20 can be installed inside the elevator vertical shaft of the circulating elevator translational track-changing system and is configured to fix and lift the car 2 when the car 2 moves to the highest or lowest floor, so that the traction rope is in an unloaded state, thereby realizing the transfer of the gravity of the car 2 from the traction rope to the translational track-changing mechanism. The aforementioned translational drive device 10 can be specifically configured to drive the translational drive device 10 and the car 2 to move together in the horizontal direction after the translational drive device 10 fixes and lifts the car 2, thereby realizing the translational track-changing of the car 2.

[0031] Thus, by applying the aforementioned translation drive device 10 to a multi-car circulating elevator, the elevator can switch car shafts during turning and track changing, ensuring smooth car operation without interference with the traction system. Simultaneously, it can effectively adjust the smoothness and comfort of the car's operation during track changing, solving the problem of inconvenient adjustment of car operation smoothness and comfort in existing multi-car circulating elevators.

[0032] Furthermore, in specific implementation, such as Figure 1 and Figure 2 As shown, when the above-mentioned circulating elevator translational track changing system also includes a car lifting device 20, the above-mentioned translational drive device 10 may also include a car lifting bracket 13. The car lifting bracket 13 is located below the base 11 and connected to the frame 12. The car lifting device 20 may be mounted on the car lifting bracket 13, thereby realizing the connection between the car lifting device 20 and the frame 12 in the above-mentioned circulating elevator translational track changing system. When the frame 12 slides horizontally under the drive of the above-mentioned drive unit, it can drive the car lifting bracket 13, the car lifting device 20 mounted on the car lifting bracket 13, and the car 2 fixed by the car lifting device 20 to move horizontally as a whole, thereby realizing the translational track changing of the car 2.

[0033] In some embodiments, the translation drive device 10 may further include a guide unit, and the frame 12 may be movably connected to the base 11 via the guide unit. The guide unit is configured to guide the sliding direction of the frame 12 to ensure that the frame 12 can slide smoothly and accurately relative to the base 11 along a preset horizontal trajectory under the drive of the drive unit. Specifically, as Figures 3 to 7 As shown, the guide unit can be disposed between the frame 12 and the base 11, and can include a guide rail 17 and a slider 18. The guide rail 17 is disposed on the base 11 and extends in a direction parallel to the sliding direction of the frame 12 (i.e., the horizontal direction mentioned above). The slider 18 is fixed on the frame 12 and slidably connected to the guide rail 17, so as to realize the movable connection of the frame 12 to the base 11 through the cooperation of the guide rail 17 and the slider 18, and at the same time provide reliable guidance for the sliding of the frame 12, thereby ensuring the stability and accuracy of the frame 12 during the sliding process, avoiding the collision or unstable operation of the car 2 during the translation and track changing due to offset or shaking, and improving the stability and reliability of the entire device operation.

[0034] Furthermore, in specific implementation, such as Figures 3 to 7As shown, the guide unit includes at least two guide rails 17. These two guide rails 17 are respectively arranged parallel to the length direction of the base 11 and symmetrically distributed on both sides of the top surface of the base 11 to provide balanced support and improve guiding stability. Each guide rail 17 can be slidably connected to multiple sliders 18. These sliders 18 are fixed to the bottom of the frame 12 and evenly distributed along the length direction of the guide rail 17 to further improve the load-bearing capacity and guiding accuracy of the frame 12 during sliding, ensuring a stable sliding trajectory even under varying load conditions during the translation of the car 2.

[0035] In some examples, the guide rail 17 can be a high-precision linear guide rail, and the slider 18 can be a linear slider with balls or rollers to effectively reduce frictional resistance during sliding, improve the smoothness and response speed of the frame 12 sliding, and at the same time ensure the guiding accuracy after long-term use.

[0036] In some examples, such as Figures 3 to 7 As shown, the guide unit includes two guide rails 17. These two guide rails 17 (i.e., the first guide rail 17A and the second guide rail 17B) are arranged parallel to each other on both sides of the top surface of the base 11 and extend along the length of the base 11.

[0037] In some embodiments, such as Figures 3 to 8 As shown, the adjustment unit is mounted on the frame 12 and may include a mounting plate 19. The drive motor 14 is fixed to the mounting plate 19, and the position of the mounting plate 19 is adjustable so that the mounting plate 19 drives the drive motor 14 and the gear 15 to move as a whole, so that the gear 15 moves closer to or further away from the rack 16, thereby achieving the purpose of adjusting the meshing gap between the gear 15 and the rack 16 in the drive unit.

[0038] Specifically, when the gear 15 is located below the rack 16, the mounting plate 19 can be set perpendicular to the horizontal plane, and the position of the mounting plate 19 in the direction perpendicular to the horizontal plane (e.g., the Z direction in the attached figure) is adjustable. That is, the mounting plate 19 can drive the drive motor 14 and the gear 15 to rise or fall together in this direction. When the gear 15 rises, it is closer to the rack 16, and when it falls, it is farther away from the rack 16, thereby realizing the adjustment of the meshing gap between the gear 15 and the rack 16.

[0039] In some specific embodiments, such as Figures 3 to 8As shown, the adjustment unit may further include a fixing plate 110 and at least one connector 111. The fixing plate 110 is fixedly connected to the frame 121, and the mounting plate 19 is mounted on one side of the fixing plate 110 in an adjustable manner via the at least one connector 111. By adjusting the mounting position of the mounting plate 19 on the fixing plate 110, the mounting plate 19 can drive the drive motor 14 and the gear 15 to move as a whole, causing the gear 15 to move closer to or away from the rack 16.

[0040] Specifically, such as Figures 3 to 8 As shown, the mounting plate 19 may have at least one position adjustment hole 112 on the side facing the fixing plate 110. Each connector 111 may correspond to one position adjustment hole 112. For example, the at least one connector 111 may correspond one-to-one with the at least one position adjustment hole 112.

[0041] Furthermore, for each connector 111, the connector 111 can be inserted into the corresponding position adjustment hole 112 and fixed to the aforementioned fixing plate 110, and the position of the connector 111 within its corresponding position adjustment hole 112 is adjustable.

[0042] In some embodiments, such as Figures 3 to 8 As shown, the aforementioned position adjustment hole 112 can specifically be an elongated through hole 112 (e.g., a waist-shaped through hole 112), and the length direction of the elongated through hole 112 can be perpendicular to the length direction of the rack 16 (e.g., the X direction in the figure). Specifically, for each connector 111, the dimension of the portion of the connector 111 within its corresponding elongated through hole 112 along the length direction of its corresponding elongated through hole 112 can be smaller than the length of its corresponding elongated through hole 112, thereby providing sufficient adjustment stroke for the mounting plate 19 to move in a direction perpendicular to the length direction of the rack 16 (e.g., the Z direction in the figure), facilitating precise control of the meshing clearance between the gear 15 and the rack 16 by adjusting the position of the mounting plate 19 in this direction.

[0043] Specifically, for each connector 111, the portion of the connector 111 within its corresponding elongated through hole 112 can have a dimension along the width direction of the corresponding elongated through hole 112 that is equal to or slightly smaller than the width of the corresponding elongated through hole 112. Thus, through the cooperation between the connector 111 and the corresponding elongated through hole 112, on the one hand, the position of the mounting plate 19 in the direction perpendicular to the length direction of the rack 16 is adjustable, and on the other hand, the displacement of the mounting plate 19 in other directions is restricted. This ensures that the drive motor 14 and gear 15 fixed to the mounting plate 19 will not undergo unnecessary offset during the adjustment process, thereby ensuring the meshing accuracy of the gear 15 and the rack 16.

[0044] In practical applications, when it is necessary to adjust the meshing clearance between gear 15 and rack 16 in the aforementioned drive unit, the connecting piece 111 can be loosened, allowing the mounting plate 19 to move freely relative to the fixed plate 110 along the length direction (i.e., the Z direction) of the elongated through hole 112. Subsequently, by moving the mounting plate 19, the drive motor 14 can move synchronously with the mounting plate 19, thereby driving the gear 15 to move closer to or away from the rack 16 until the required meshing clearance is achieved between the gear 15 and rack 16. Then, the connecting piece 111 is tightened again, so that the mounting plate 19 is re-fixed on the fixed plate 110, thus completing the precise adjustment of the meshing clearance. This adjustment method is simple to operate, requires no complicated disassembly process, and can quickly respond to and resolve meshing problems caused by long-term operation or accumulated installation errors, significantly improving the ease of maintenance and operational reliability of the equipment.

[0045] In some examples, the aforementioned connector 111 can be a bolt assembly, including a bolt and a nut. The bolt passes through the elongated through-hole 112 on the mounting plate 19 and connects to the threaded hole on the fixing plate 110, while the nut is tightened onto the bolt to fix the position of the mounting plate 19. When it is necessary to adjust the meshing clearance between the gear 15 and the rack 16 in the aforementioned drive unit, simply loosen the nut, move the mounting plate 19 to the appropriate position, and then tighten the nut to fix the mounting plate 19.

[0046] In some specific embodiments, such as Figures 3 to 8 As shown, the drive unit may further include a main shaft 113, which is connected between the drive motor 14 and the gear 15, and the drive motor 14 drives the gear 15 to rotate through the main shaft 113. Specifically, the two opposite ends of the main shaft 113 along its length are respectively connected to the output shaft of the drive motor 14 and the center hole of the gear 15 to ensure efficient and stable power transmission.

[0047] In some examples, such as Figures 3 to 8 As shown, the drive unit includes two racks 16, which are arranged in parallel and spaced apart. Correspondingly, the drive unit also includes two gears 15, which mesh with the two racks 16 respectively to form a two-point meshing drive structure, thereby improving transmission smoothness and load balance.

[0048] Furthermore, if the drive unit also includes a spindle 113, the number of spindles 113 included in the drive unit can also be two. One end of each of the two spindles 113 is connected to the two gears 15 respectively, and the other end is connected to the drive motor 14 respectively. The drive motor 14 drives the two spindles 113 to rotate, so as to drive the two gears 15 to rotate synchronously.

[0049] In some examples, the drive motor 14 may include a reducer fixedly connected to the mounting plate 19, and the two ends of the main shaft 113 may be connected to the output shaft of the reducer and the center hole of the corresponding gear 15, respectively. For example, the main shaft 113 may be connected to the output shaft of the reducer through a coupling 114.

[0050] In some embodiments, such as Figures 3 to 8 As shown, the drive unit may further include a bearing housing 115 and a bearing housing plate 116. The bearing housing 115 is sleeved on the outer periphery of the main shaft 113 and is mounted on the mounting plate 19 through the bearing housing plate 116, thereby realizing the rotational connection between the main shaft 113 and the mounting plate 19 through the bearing housing 115, so as to improve the stability and support strength of the main shaft 113 when rotating.

[0051] Specifically, the bearing housing plate 116 can be vertically fixed to one side of the mounting plate 19, and the bearing housing 115 is fixed on the bearing housing plate 116. The main shaft 113 passes through the bearing in the bearing housing 115, so that the main shaft 113 can rotate smoothly around its own axis under the drive of the drive motor 14, effectively reducing the radial runout and axial movement of the main shaft 113 when rotating at high speed or bearing load, thereby ensuring the meshing accuracy and transmission efficiency between the gear 15 and the rack 16, and reducing the noise and mechanical wear caused by the shaking of the main shaft 113.

[0052] Furthermore, in specific implementation, for each spindle 113, multiple bearing seats 115 can be fitted around its outer periphery, and these multiple bearing seats 115 can be fixedly connected to a bearing seat plate 116 corresponding to that spindle 113. This design can further improve the stability of the spindle 113 during high-speed rotation, distribute the radial force borne by each spindle 113, avoid shaft deformation or increased vibration caused by single-point support, thereby extending the service life of the spindle 113 and related transmission components, and ensuring the long-term stable operation of the drive unit.

[0053] In some examples, such as Figures 3 to 8 As shown, for each spindle 113, two bearing seats 115 can be sleeved on the outer periphery of the spindle 113. These two bearing seats 115 can be respectively located at one end of the spindle 113 near the corresponding gear 15 and the other end of the spindle 113 near the drive motor 14 (e.g., reducer), forming support for both ends of the spindle 113. This allows the spindle 113 to maintain good coaxiality when transmitting torque, reducing the impact and noise during the meshing process of the gear 15 and rack 16 corresponding to the spindle 113, and further ensuring the smoothness and reliability of the translation drive device 10.

[0054] In some specific embodiments, such as Figures 3 to 8As shown, the adjustment unit may further include an inter-plate connector 117, and the fixed plate 110 has a first side plate 110a, the bearing seat plate 116 has a second side plate 116a, the first side plate 110a and the second side plate 116a are arranged at intervals relative to each other in a direction perpendicular to the horizontal plane (for example, the Z direction in the figure), and are connected together by the inter-plate connector 117. Furthermore, the length of the inter-plate connector 117 between the first side plate 110a and the second side plate 116a is adjustable. By adjusting the length of the inter-plate connector 117 between the first side plate 110a and the second side plate 116a, precise displacement of the bearing seat plate 116, bearing seat 115 and main shaft 113 as a whole in a direction perpendicular to the horizontal plane can be achieved, thereby fine-tuning the meshing clearance between the gear 15 and the rack 16.

[0055] Specifically, at least one bolt hole may be provided on the first side plate 110a, and the inter-plate connector 117 may be connected to the corresponding bolt hole on the first side plate 110a.

[0056] Specifically, at least one bolt hole may be provided on the second side plate 116a, and the inter-plate connector 117 may be connected to the corresponding bolt hole on the second side plate 116a.

[0057] In some examples, the inter-plate connector 117 can be a screw 117 (e.g. Figure 5 As shown), the two opposite ends of the screw 117 can be connected to the corresponding bolt holes on the first side plate 110a and the second side plate 116a respectively through nuts.

[0058] Specifically, the screw 117 can pass through the corresponding bolt holes on the first side plate 110a and the second side plate 116a. The length of the portion of the screw 117 passing through the corresponding bolt hole on the first side plate 110a and / or the length of the portion of the screw 117 passing through the corresponding bolt hole on the second side plate 116a can be adjusted to adjust the length of the screw 117 between the first side plate 110a and the second side plate 116a. After adjusting the length of the screw 117 between the first side plate 110a and the second side plate 116a, the screw 117 can be tightened and fixed to the corresponding bolt hole on the first side plate 110a and the corresponding bolt hole on the second side plate 116a using a nut.

[0059] In some examples, the aforementioned fixing plate 110 can be composed of a horizontal fixing plate (i.e., the aforementioned first side plate 110a) and a vertical fixing plate fixedly connected together. The horizontal fixing plate is fixedly connected to the aforementioned frame 12 to achieve a stable connection between the fixing plate 110 and the frame 12. The vertical fixing plate is set perpendicular to the horizontal fixing plate, and the aforementioned mounting plate 19 is mounted on the vertical fixing plate to provide a mounting reference surface for the mounting plate 19, ensuring that the mounting plate 19 maintains a stable posture during adjustment. Specifically, threaded holes for mounting connectors 111 can be provided on the vertical fixing plate as needed. The position and number of these threaded holes match the elongated through holes 112 on the mounting plate 19 to achieve position adjustment of the mounting plate 19. Through this structural design, the fixing plate 110 not only provides a reliable mounting carrier for the drive unit and adjustment unit but also effectively disperses and transmits the forces generated during the drive process, preventing excessive local stress on the frame 12 and thus ensuring the structural rigidity and operational stability of the entire translation drive device 10.

[0060] In some embodiments, such as Figures 3 to 10 As shown, the aforementioned translation drive device 10 may further include an oil box 122. The oil box 122 is located directly below the gear 15, and has an opening at its top. The oil box 122 is fixedly connected to the bearing seat 115 near the gear 15, and is used to collect the lubricating oil dripping during the meshing of the gear 15, preventing the lubricating oil from dripping directly onto components such as the base 11 or guide rail 17 and causing contamination. It also facilitates the recycling and reuse of the lubricating oil, reducing maintenance costs. The inner wall of the oil box 122 may have an inclined surface to allow the lubricating oil to collect at the bottom of the oil box 122, facilitating regular cleaning and replacement. Furthermore, the opening size of the oil box 122 is slightly larger than the outer diameter of the gear 15, ensuring that all lubricating oil splashed out during the rotation of the gear 15 can be collected, further improving the cleanliness of the device's operating environment.

[0061] In some specific embodiments, such as Figures 3 to 10As shown, the aforementioned translation drive device 10 may further include a lubricating felt wheel, which is fixedly connected to the mounting plate 19 and configured to lubricate the rack 16. Specifically, the lubricating felt wheel and the gear 15 are located on the same side of the rack 16, and the outer circumferential surface of the lubricating felt wheel contacts the tooth surface of the rack 16. The lubricating felt wheel contains lubricating oil. When the gear 15 drives the mounting plate 19 to move along the rack 16, the lubricating felt wheel rolls accordingly, evenly applying the absorbed lubricating oil to the tooth surface of the rack 16, thereby continuously lubricating the meshing parts of the gear 15 and the rack 16. This design effectively reduces friction and wear between the gear 15 and the rack 16, reduces transmission noise, extends the service life of transmission components, reduces the workload of regular manual lubrication, and improves the convenience of equipment maintenance. The installation position of the lubricating felt wheel can be adjusted according to the specific position of the rack 16 to ensure good contact with the tooth surface of the rack 16, guaranteeing the uniformity and reliability of the lubrication effect.

[0062] In some examples, such as Figures 3 to 10 As shown, the aforementioned lubricating felt wheel may include a felt gear 123 and an oil supply shaft 124. The oil supply shaft 124 is fixedly connected to the mounting plate 19. The felt gear 123 is mounted on the oil supply shaft 124 and rotatably connected to it. Multiple oil outlet holes 125 are evenly distributed on the radial circumferential surface of the felt gear 123. The oil supply shaft 124 is provided with an oil passage hole 126, and the oil outlet holes 125 communicate with the oil passage hole 126. Furthermore, the felt gear 123 meshes with the rack 16, thereby allowing the felt gear 123 to move with the mounting plate 19. When the gear moves and meshes with the rack 16, the lubricating oil in the oil supply shaft 124 enters the oil outlet 125 through the oil passage shaft hole 126 and penetrates to the tooth surface of the felt gear 123. As a result, during the meshing process between the felt gear 123 and the rack 16, the lubricating oil is evenly brushed onto the tooth surface of the rack 16, achieving a real-time lubrication effect. This effectively reduces the friction and wear between the gear 15 and the rack 16, extends the service life of the transmission components, and ensures the smoothness of the meshing transmission. Therefore, it improves the operational stability of the translation drive device 10 and enhances the smoothness of the car 2's translation and track changing.

[0063] Furthermore, in specific implementation, an oil connector 127 can be provided on the aforementioned oil supply shaft 124. The oil connector 127 is connected to an oil pipe and supplies oil to the aforementioned felt gear 123 through an oil pump. A sealed arrangement is provided between the felt gear 123 and the oil supply shaft 124 to ensure that no oil leakage occurs during the rotation of the felt gear 123 around the oil supply shaft 124.

[0064] In a specific application scenario, the aforementioned circulating elevator translation and track-changing system includes multiple elevator vertical shafts, comprising at least one elevator vertical shaft for upward travel (hereinafter referred to as the upward shaft) and at least one elevator vertical shaft for downward travel (hereinafter referred to as the downward shaft). Accordingly, as... Figure 1 and Figure 2 As shown, the operation process of the above-mentioned circulating elevator translation and track changing system may include: (1) The upward step includes: the traction rope in the upward shaft is connected to the car 2, the traction rope in the downward shaft is unloaded, and under the balancing effect of the counterweight, the traction machine drives the traction rope in the upward shaft and the downward shaft at the same time, thereby driving the car 2 to move upward in the upward shaft.

[0065] (2) Upward to downward transition steps: After the car 2 runs along the upward shaft to the top floor, the traction machine stops working. The limiting device 30 in the upward shaft fixes the position of the traction rope to prevent the traction rope from slipping due to the weight imbalance on both sides of the traction machine when the car 2 is subjected to subsequent force conversion. Then, the car lifting device 20 fixes the car 2 and lifts it a distance, so that the traction ropes in both the upward and downward shafts are in an unloaded state. Then, the unhooking mechanism located in the upward shaft causes the traction rope in the upward shaft to detach from the car 2. The translation drive device 10 drives the car lifting device 20 and the car 2 to move horizontally to the top floor of the downward shaft. Subsequently, the unhooking mechanism located in the downward shaft connects the traction rope in the downward shaft to the car 2. The car lifting device 20 drives the car 2 to descend a distance, so that the traction rope in the downward shaft is subjected to force and is no longer fixed to the car 2, allowing the car 2 to descend, thus completing the track change.

[0066] (3) Downward step: The traction rope in the downward shaft is connected to the car 2, and the traction rope in the upward shaft is unloaded. Under the balancing effect of the counterweight, the traction machine drives the traction ropes in the upward shaft and the downward shaft at the same time, thereby driving the car 2 to move downward in the downward shaft.

[0067] (4) Downward to Upward Step: After the car 2 runs along the downward shaft to the lowest floor, the traction machine stops working. The limiting device 30 in the downward shaft fixes the position of the traction rope to prevent the traction rope from slipping due to the weight imbalance on both sides of the traction machine when the car 2 is subjected to subsequent force conversion. Then, the car lifting device 20 fixes the car 2 and lifts it a distance, so that the traction ropes in the upward and downward shafts are in an unloaded state. Then, the unhooking mechanism located in the downward shaft causes the traction rope in the downward shaft to detach from the car 2. The translation drive device 10 drives the car lifting device 20 and the car 2 to move horizontally to the lowest position of the upward shaft. Subsequently, the unhooking mechanism located in the upward shaft connects the traction rope in the upward shaft to the car 2. The car lifting device 20 drives the car 2 to descend a distance, so that the traction rope in the upward shaft is subjected to force and is no longer fixed to the car 2, allowing the car 2 to rise, thus completing the track change.

The configuration adjusts the meshing clearance between the gear and rack in the drive unit. By adjusting the meshing clearance between the gear and rack, it can effectively solve the problems of unstable transmission, reduced positioning accuracy, and abnormal vibration caused by the increased meshing clearance between the gear and rack in the existing circulating elevator translation drive system after long-term operation due to factors such as installation errors and component wear. This effectively improves the smoothness and comfort of the translation drive during the translation of the car, thus improving the smoothness and comfort of the car translation and track changing process in multi-car circulating elevators, ensuring the safety and smooth comfort of the car operation, and enhancing the passenger riding experience.
