Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to a car lifting and pin telescopic device, a translation and track changing mechanism, and related systems. Background Technology

[0002] 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, since traditional elevators occupy one shaft per car, the transportation efficiency of elevators decreases as the 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 more and more of the building area, thereby reducing the usable area of ​​the building and making it difficult to save costs.

[0003] The circulating elevator divides the vertical shaft into functional sections. Each vertical shaft is mainly used for going up or down. During track changing, the unhooking mechanism can easily connect and disconnect the traction rope from the car, allowing multiple cars to circulate in the vertical shaft. This changes the traditional elevator system where only one car can run in a single shaft, improving the operating quality of elevators in high-rise and super high-rise buildings.

[0004] However, in the existing technology, the safety and smooth comfort of the car during the switching of the vertical shaft in the circulating elevator cannot be effectively guaranteed due to the lack of a stable and reliable force transfer scheme. Summary of the Invention

[0005] This application provides a car lifting and pin telescopic device, a translational rail changing mechanism, and related systems to provide a force conversion scheme that can transfer the car's gravity from the traction steel wire rope to the translational rail changing mechanism during the car's vertical shaft switching process, thereby ensuring the safety and smooth comfort of the car during operation.

[0006] This application provides a car lifting and pin telescopic device, which is applied to a circulating elevator translational track-changing system. The circulating elevator translational track-changing system includes an elevator vertical shaft, a car, and a translational drive device. When the car is inside the elevator vertical shaft, it can be raised and lowered by a traction rope inside the shaft to reach the highest or lowest floor. The car lifting and pin telescopic device is configured to fix and lift the car when it reaches the highest or lowest floor, so that the traction rope is in an unloaded state. The translational drive device is configured to... After the car is fixed and lifted, the car lifting and pin extension device is driven to move horizontally along with the car as a whole. The car lifting and pin extension device includes a mounting frame and multiple lifting and pin extension device units. The multiple lifting and pin extension device units are symmetrically arranged on the mounting frame along the car lifting direction, and each lifting and pin extension device unit includes a lifting mechanism and a pin extension mechanism. The lifting mechanism is configured to lift the car when the car moves to the highest or lowest floor, and the pin extension mechanism is configured to fix the car and bear the weight of the car during the lifting process.

[0007] The lifting mechanism includes a lifting frame, a lifting guide assembly, and a first drive unit. The lifting frame is slidably mounted on the mounting frame in the direction of car lifting. The lifting guide assembly is disposed between the lifting frame and the mounting frame and is configured to guide the sliding direction of the lifting frame. The first drive unit is connected to the lifting frame and is configured to drive the lifting frame to slide in the direction of car lifting.

[0008] The lifting guide assembly includes a guide rail and a slider. The guide rail is mounted on the mounting frame along the car lifting direction, and the slider is fixed on the lifting frame and slidably connected to the guide rail. The lifting mechanism also includes a precision positioning plate, which is disposed between the mounting frame and the guide rail and includes multiple mounting surfaces. The multiple mounting surfaces are located on the side of the precision positioning plate facing the mounting frame and are connected to the mounting frame. The guide rail is mounted on the side of the precision positioning plate away from the mounting frame.

[0009] The latch telescopic mechanism includes a second drive unit and multiple latch assemblies. Each latch assembly includes a latch that is slidably connected to the lifting mechanism. The outer periphery of the car is provided with multiple latch positioning holes, which are respectively for the latches of the multiple latch assemblies to be inserted. The second drive unit is configured to synchronously drive the latches of the multiple latch assemblies so that the latches of the multiple latch assemblies can be simultaneously inserted into or disengaged from the multiple latch positioning holes.

[0010] The pin telescopic mechanism further includes a pin connecting plate, which is mounted on the second drive unit; and each pin assembly further includes a synchronization fixing block, wherein in each pin assembly, the pin is fixedly connected to the synchronization fixing block, and the synchronization fixing block is fixedly connected to the pin connecting plate.

[0011] Each of the pin assemblies further includes multiple copper sleeve seats and multiple guide copper sleeves; and in each pin assembly, the multiple copper sleeve seats are respectively fixedly connected to the lifting frame, the multiple guide copper sleeves are installed one-to-one inside the multiple copper sleeve seats, and the pins pass through the multiple guide copper sleeves and are respectively slidably connected to the multiple guide copper sleeves.

[0012] In each of the latch assemblies, the latch includes a square head, which is connected to the end of the pin shaft of the latch. The upper surface of the square head is provided with a fixing groove. The square head cooperates with the latch positioning hole. After the square head is inserted into the latch positioning hole, the fixing groove and the inner sidewall of the latch positioning hole form a limiting cooperation to fix the car.

[0013] Each of the latches further includes a proximity switch and a proximity switch plate. In each latch assembly, the proximity switch is installed at the end of the latch head, and the proximity switch plate is disposed on the car at a position corresponding to the latch positioning hole and is used to receive the signal from the proximity switch.

[0014] This application embodiment also provides a translational track-changing mechanism, which is applied to a circulating elevator translational track-changing system. The circulating elevator translational track-changing system includes an elevator vertical shaft and a car. When the car is inside the elevator vertical shaft, it can be raised and lowered and moved to the highest or lowest floor under the traction of the traction rope inside the elevator vertical shaft. The translational track-changing mechanism includes: a car lifting and pin telescopic device as described in any of the above claims, configured to fix and lift the car when the car moves to the highest or lowest floor, so that the traction rope is in an unloaded state; and a translational drive device, configured to drive the car lifting and pin telescopic device and the car as a whole to move horizontally after the car lifting and pin telescopic device fixes and lifts the car.

[0015] This application also provides a circulating elevator translation and track changing system, which includes the translation and track changing mechanism described above.

[0016] The beneficial effects of this application are as follows: The car lifting and pin telescopic device, translational track changing mechanism, and related system provided in this application are applied to the translational track changing system of a circulating elevator. The car lifting and pin telescopic device includes a mounting frame and multiple lifting and pin telescopic device units. These multiple lifting and pin telescopic device units are symmetrically arranged on the mounting frame along the car lifting direction. Each lifting and pin telescopic device unit includes a lifting mechanism and a pin telescopic mechanism. The lifting mechanism is configured to lift the car when it moves to the highest or lowest floor, and the pin telescopic mechanism is configured to fix the car and bear its weight during the lifting process. This system enables the car to rise and fall under the traction of the traction rope inside the elevator shaft and move to the highest or lowest floor. The car lifting and pin telescopic device then fixes and lifts the car, leaving the traction rope unloaded. This allows the car's weight to be transferred from the traction rope to the translational track-changing mechanism, ensuring the stability and safety of the car during the translational track-changing process. This effectively solves the problem in existing circulating elevators where, during the translational track-changing process when switching vertical shafts, the lack of a force conversion device to transfer the car's weight from the traction rope to the translational track-changing mechanism results in compromised safety and smooth comfort during car operation.

[0027] Please see Figures 1 to 7 , 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 the embodiments of this application.

Figure 4 yes Figure 3 Enlarged view of the structure inside the circular frame C1. Figure 5 This is a front view schematic diagram of the car lifting and pin telescopic device provided in this application embodiment applied to a circulating elevator translation and track changing system. Figure 6 This is a left-side structural schematic diagram of the car lifting and pin telescopic device provided in this application embodiment applied to a circulating elevator translation and track changing system. Figure 7 This is a top view schematic diagram of the car lifting and pin telescopic device provided in the embodiments of this application applied to a circulating elevator translation and track changing system. Figures 1 to 7As shown, the circulating elevator translational track changing system includes an elevator vertical shaft, a car 2, a translational drive device 20, and any of the car lifting and pin extension devices 10 provided in the embodiments of this application. The car lifting and pin extension device 10 and the translational drive device 20 together constitute a translational track changing mechanism for translating and changing the track of the car 2, and the translational drive mechanism can drive the car lifting and pin extension device 10 to move in the horizontal direction (for example, the X direction in the figure).

[0028] Specifically, in the above-mentioned circulating elevator translational track-changing system, when the car 2 is inside the elevator vertical shaft, it can be lifted and moved to the highest or lowest floor by the traction of the traction rope inside the elevator vertical shaft. The car lifting and pin telescopic device 10 is installed inside the elevator vertical shaft 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, so as to realize the transfer of the gravity of the car 2 from the traction rope to the translational track-changing mechanism. The translational drive device 20 is configured to drive the car lifting and pin telescopic device 10 and the car 2 to move horizontally together after the car lifting and pin telescopic device 10 fixes and lifts the car 2, so as to realize the translational track-changing of the car 2.

[0029] In this embodiment, the car lifting and pin telescopic device 10 may include a mounting frame 100 and a plurality of lifting and pin telescopic device units 200. The plurality of lifting and pin telescopic device units 200 are symmetrically arranged on the mounting frame 100 along the lifting direction of the car 2 (for example, the Z direction in the figure) to ensure that the car 2 can be smoothly and symmetrically fixed and lifted after moving to the highest or lowest floor, avoiding tilting or jamming caused by uneven force.

[0030] In some examples, such as Figure 1 and Figure 2 As shown, the number of lifting and pin telescopic device units 200 included in the above-mentioned car lifting and pin telescopic device 10 can be specifically two, and these two lifting and pin telescopic device units 200 (i.e., the first lifting and pin telescopic device unit 200A and the second lifting and pin telescopic device unit 200B) are symmetrically arranged on the mounting frame 100 along the lifting direction of the car 2.

[0031] In this embodiment, as Figures 3 to 7As shown, in the above-mentioned car lifting and pin telescopic device 10, each lifting and pin telescopic device unit 200 may include a lifting mechanism 11 and a pin telescopic mechanism 12. The lifting mechanism 11 is configured to lift the car 2 when the car 2 moves to the highest or lowest floor. The pin telescopic mechanism 12 is configured to fix the car 2 and bear the weight of the car 2 during the lifting process. This allows the weight of the car 2 to be completely transferred to the translation and track changing mechanism after the lifting of the car 2 is completed. This makes the traction rope currently pulling the car 2 up and down in an unloaded state, which facilitates the disengagement mechanism inside the elevator vertical shaft to disengage the traction rope from the car 2. At the same time, it provides safe and stable support for the subsequent translation and track changing operation, effectively reducing the risk of the car 2 shaking or deviating during the translation and track changing process, and improving the safety and smoothness of the car 2 during operation.

[0032] In some embodiments, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the lifting mechanism 11 may include a lifting frame 111 and a first drive unit 112. The lifting frame 111 is mounted on the mounting frame 100 in a manner that allows it to slide along the lifting direction of the car 2. The first drive unit 112 is connected to the lifting frame 111 and is configured to drive the lifting frame 111 to slide along the lifting direction of the car 2. The pin telescopic mechanism 12 is mounted on the lifting frame 111 of the lifting mechanism 11, for example, on the top of the lifting frame 111. This allows the lifting frame 111 of the lifting mechanism 11 to drive the pin telescopic mechanism 12 to slide synchronously along the lifting direction of the car 2 under the drive of the first drive unit 112.

[0033] Specifically, in the aforementioned car lifting and pin telescopic device 10, the working process of each lifting and pin telescopic device unit 200 can be as follows: when the car 2 moves to the highest or lowest floor, the lifting and pin telescopic device unit 200 drives the lifting frame 111 to rise through the first drive unit 112, causing the pin telescopic mechanism 12 mounted on the lifting frame 111 to approach the pre-set pin positioning hole 2A on the side of the car 2, thereby achieving the positioning of the pin telescopic mechanism 12 in the pin positioning hole 2A, thus completing the process. The car 2 is fixed in pairs. After the car 2 is fixed by the pin telescopic mechanism 12, the lifting and pin telescopic device unit 200 continues to drive the lifting frame 111 to rise through the first drive unit 112. At this time, the lifting frame 111 drives the car 2 to rise synchronously through the pin telescopic mechanism 12. As the car 2 rises, the traction rope, which was originally in a taut state, gradually loosens until the weight of the car 2 is completely borne by the pin telescopic mechanism 12 and the lifting frame 111, and the traction rope is completely unloaded. It can be understood that during the process of the lifting frame 111 of the lifting and pin telescopic device unit 200 driving the car 2 to rise synchronously through the pin telescopic mechanism 12, the pin telescopic mechanism 12 not only has to bear the weight of the car 2, but also needs to ensure that there is no relative displacement between the car 2 and the lifting frame 111 during the lifting process, so as to ensure the accuracy and stability of the subsequent translation and track changing operation.

[0034] Specifically, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the lifting mechanism 11 may further include a lifting guide assembly 113. The lifting guide assembly 113 is disposed between the lifting frame 111 and the mounting frame 100 and is configured to guide the sliding direction of the lifting frame 111 to ensure that the lifting frame 111 can make precise and stable linear movements along the lifting direction of the car 2 under the drive of the first drive unit 112, and avoid deviation or jamming.

[0035] In some examples, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the first drive unit 112 can be specifically a lifting electric cylinder 112. The lifting electric cylinder 112 is located at the bottom of the lifting frame 111, and the cylinder body and cylinder rod of the lifting electric cylinder 112 can be connected to the mounting frame 100 and the lifting frame 111 respectively. Thus, the lifting frame 111 can be driven to slide along the lifting direction of the car 2 by the telescopic movement of the lifting electric cylinder 112, thereby completing the lifting and fixing of the car 2.

[0036] In some specific embodiments, such as Figures 3 to 10As shown, in each lifting and pin telescopic device unit 200, the lifting guide assembly 113 may include a guide rail 1131 and a slider 1132. The guide rail 1131 is arranged on the mounting frame 100 along the lifting direction of the car 2, and the slider 1132 is fixed on the lifting frame 111 and slidably connected to the guide rail 1131. This allows the lifting frame 111 to be slidably mounted on the mounting frame 100 through the cooperation of the guide rail 1131 and the slider 1132, while providing reliable guidance for the sliding of the lifting frame 111, thereby ensuring the accuracy and smoothness of the lifting action.

[0037] Specifically, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the lifting guide assembly 113 includes multiple sliders 1132. These multiple sliders 1132 are divided into two groups. These two groups of sliders 1132 are arranged at intervals along a direction perpendicular to the lifting direction of the car 2 and fixed on the same side of the lifting frame 111. Each group of sliders 1132 can be composed of at least one slider 1132 arranged at intervals along the lifting direction of the car 2 to enhance the guiding rigidity and load-bearing capacity, effectively disperse the lateral force on the lifting frame 111 during the movement, and avoid wear or deformation caused by single-point force.

[0038] Specifically, such as Figures 3 to 7 As shown, in each lifting and pin telescopic device unit 200, the lifting mechanism 11 may further include a precision positioning plate 114. The precision positioning plate 114 is disposed between the mounting frame 100 and the guide rail 1131, and includes multiple mounting surfaces. These mounting surfaces are located on the side of the precision positioning plate 114 facing the mounting frame 100 and are fixedly connected to the mounting frame 100. The guide rail 1131 is mounted on the side of the precision positioning plate 114 away from the mounting frame 100. Thus, through the multi-faceted mounting structure of the precision positioning plate 114, the installation accuracy and stability of the guide rail 1131 are effectively improved, thereby ensuring the straightness and repeatability of the lifting frame 111 during movement.

[0039] For example, such as Figures 3 to 10 As shown, the number of mounting surfaces included in the aforementioned precision positioning plate 114 can be specifically three, and these three mounting surfaces are respectively in contact with and fixed to the surfaces of the mounting frame 100 in different directions. For example, they can be respectively fixedly connected to the surfaces of the mounting frame 100 in different directions by screws.

[0040] For example, the aforementioned precision positioning plate 114 can be made of high-strength metal material, which has good rigidity and durability, and can maintain structural non-deformation during long-term operation, further ensuring the stability and reliability of the movement of the lifting frame 111.

[0041] In the above embodiments, such as Figures 3 to 10As shown, in each lifting and pin telescopic device unit 200, the aforementioned pin telescopic mechanism 12 may include a second drive unit 121 and multiple pin assemblies 122. Each pin assembly 122 includes a pin 122A that is slidably connected to the aforementioned lifting mechanism 11 (e.g., the top of the aforementioned lifting mechanism 11). The outer periphery of the aforementioned car 2 may be provided with multiple pin positioning holes 2A, which are respectively for the insertion of the pins 122A of the aforementioned multiple pin assemblies 122. The aforementioned second drive unit 121 is configured to synchronously drive the pins 122A of the aforementioned multiple pin assemblies 122, so that the pins 122A of the aforementioned multiple pin assemblies 122 can be simultaneously inserted into or disengaged from the multiple pin positioning holes 2A, thereby ensuring that the pins 122A of each pin assembly 122 move in a consistent manner, avoiding structural jamming or uneven force due to insertion deviation, and improving safety and control accuracy. Furthermore, this method of multiple pins working together can effectively disperse the horizontal force that may be generated in the car 2, avoid excessive force on the pin 122A of a single pin assembly 122, which could lead to deformation or damage, and extend the service life of the pin telescopic mechanism 12.

[0042] Specifically, in each lifting and pin extension device unit 200, each pin assembly 122 can correspond to a pin positioning hole 2A, and can be inserted into or disengaged from its corresponding pin positioning hole 2A under the drive of the second drive unit 121, thereby achieving reliable locking and release of the lifted car 2.

[0043] Specifically, in each lifting and pin telescopic device unit 200, the second drive unit 121 can be connected to the top of the lifting frame 111, and the plurality of pin assemblies 122 can be slidably connected to the top of the lifting frame 111 and symmetrically arranged on both sides of the second drive unit 121 to ensure balanced force and synchronized movement.

[0044] In some specific embodiments, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the aforementioned pin telescopic mechanism 12 may further include a pin connecting plate 123, which is mounted on the aforementioned second drive unit 121. Furthermore, each pin assembly 122 may further include a synchronous fixing block 122B. In each pin assembly 122, the pin 122A may pass through the synchronous fixing block 122B and be fixedly connected to the synchronous fixing block 122B. The synchronous fixing block 122B is fixedly connected to the pin connecting plate 123, so that the pin 122A is fixedly connected to the pin connecting plate 123 through the synchronous fixing block 122B. This allows the pin connecting plate 123 to simultaneously drive the pins 122A of the aforementioned multiple pin assemblies 122 to telescopically move under the drive of the second drive unit 121, ensuring that the pins 122A of each pin assembly 122 maintain a consistent stroke and force during insertion or withdrawal.

[0045] Specifically, such as Figure 11 and Figure 12 As shown, in each pin assembly 122, a first keyway 12211 can be provided on the pin shaft 1221 of pin 122A, and a second keyway 122B1 can be provided on the synchronous fixing block 122B. The first keyway 12211 and the second keyway 122B1 are fixedly connected by a key 122C to achieve a fixed connection between pin 122A and synchronous fixing block 122B. This keyed connection method not only facilitates assembly and disassembly but also effectively absorbs vibration and impact during mechanical operation, reduces component wear, and improves the overall durability of the mechanism.

[0046] Specifically, such as Figure 11 and Figure 12 As shown, each pin assembly 122 may further include a clamp 122D. In each pin assembly 122, the clamp 122D is sleeved and fixed on the pin shaft 1221 of the pin 122A and fixedly connected to the synchronous fixing block 122B, so that the pin 122A is fixedly connected to the synchronous fixing block 122B through the clamp 122D. For example, the clamp 122D can be locked to the pin shaft 1221 of the pin 122A with screws. Along the axial direction of the pin shaft 1221 of the pin 122A, the clamp 122D and the synchronous fixing block 122B can be fixedly connected by screws. The clamp 122D not only enhances the guiding nature of the pin 122A during movement, but also effectively prevents the pin 122A from deflecting or shaking when subjected to force, further improving the action accuracy and reliability of the pin telescopic mechanism 12. Meanwhile, the bolt connection between clamp 122D and synchronous fixing block 122B facilitates disassembly and maintenance, ensuring structural strength while also facilitating later maintenance.

[0047] In some examples, the second drive unit 121 described above may specifically be a DC motor 121. The push-pull force converted from the power and torque of the linear motor 122, that is, the telescopic force that provides extension and retraction of the pin 122A, is much smaller than the frictional force between the pin 122A and the car 2.

[0048] In some examples, such as Figures 3 to 10 As shown, in each lifting and pin telescopic device unit 200, the number of pin components 122 included in the aforementioned pin telescopic mechanism 12 can be specifically two, and these two pin components 122 can be symmetrically arranged on both sides of the second drive unit 121, and are linked with the pin connecting plate 123 through two synchronous fixing blocks 122B respectively to ensure consistent operation.

[0049] In some specific embodiments, such as Figure 11 and Figure 12As shown, each pin assembly 122 may further include multiple copper sleeve seats 122E and multiple guide copper sleeves 122F. In each pin assembly 122, the multiple copper sleeve seats 122E are fixedly connected to the aforementioned lifting frame 111, and the multiple guide copper sleeves 122F are correspondingly installed inside the multiple copper sleeve seats 122E. Pins 122A pass through the multiple guide copper sleeves 122F and are slidably connected to them, thereby achieving a sliding connection between the pins 122A of each pin assembly 122 and the lifting frame 111, while ensuring the straightness and stability of the pins 122A during extension and retraction. The guide copper sleeves 122F are made of self-lubricating material, enabling continuous operation without additional lubrication and reducing maintenance frequency. The copper sleeve seats 122E are fixed to the lifting frame 111 with high-strength bolts, providing a firm connection and good vibration resistance. This structural design effectively distributes the force on the pins, avoids localized wear, and extends service life.

[0050] Specifically, in each pin assembly 122, the aforementioned plurality of copper sleeves 122E can be respectively arranged on both sides of the aforementioned synchronous fixing block 122B along the axial direction of the pin 122A, so as to balance the force distribution of the pin 122A in reciprocating motion and reduce the risk of wear and deformation caused by off-center load.

[0051] In some specific embodiments, such as Figure 11 and Figure 12 As shown, in each pin assembly 122, the pin 122A may include a pin head 1222, which is connected to the end of the pin shaft 1221 of the pin 122A. The upper end face of the pin head 1222 is provided with a fixing groove 12221. The pin head 1222 cooperates with the corresponding pin positioning hole 2A. After the pin head 1222 is inserted into the corresponding pin positioning hole 2A, the fixing groove 12221 forms a limiting cooperation with the inner side wall of the corresponding pin positioning hole 2A to fix the car 2.

[0052] Specifically, the inner wall of the aforementioned pin positioning hole 2A can be provided with a protruding structure 2B that matches the fixing groove 12221. When the pin square head 1222 is fully inserted into the pin positioning hole 2A and raised to a predetermined height, the protruding structure 2B will be locked into the fixing groove 12221 on the upper end face of the pin square head 1222, forming a mechanical limit, thereby effectively preventing the car 2 from falling off due to the relative sliding between the pin 122A and the pin positioning hole 2A during the lifting or translation process. Even if the aforementioned second drive unit 121 (e.g., linear motor 121) malfunctions, the pin 122A will not detach from the car 2, effectively preventing the abnormal retraction of the pin 122A when it supports the car 2, which would cause the car 2 to fall, further improving the safety and comfort of the car 2 during operation. Furthermore, the way the fixed groove 12221 and the protruding structure 2B cooperate not only achieves vertical load-bearing limitation, but also limits the slight displacement of the car 2 in the horizontal direction to a certain extent, providing a more stable initial posture for subsequent translation and track changing operations.

[0053] It should be noted that in this embodiment, the design of the pin head 1222 increases the contact area with the pin positioning hole 2A, allowing the gravity of the car 2 to be transmitted more evenly to the pin telescopic mechanism 12, thus avoiding structural damage caused by local stress concentration. Furthermore, the dimension of the pin positioning hole 2A in the car 2's lifting direction is larger than the dimension of the pin head 1222 in the car 2's lifting direction, so as to reserve lifting space for the pin head 1222 to form a limiting fit with the protruding structure 2B after insertion. Specifically, when the square head of the pin 1222 is initially inserted into the pin positioning hole 2A, the upper surface of the square head of the pin 1222 (i.e., the surface where the fixing groove 12221 is located) is lower than the lower surface of the protruding structure 2B. At this time, the lifting mechanism 11 drives the lifting frame 111 to move the entire pin assembly 122 upward, so that the square head of the pin 1222 slides upward in the pin positioning hole 2A until the protruding structure 2B is engaged in the fixing groove 12221, completing the lifting and locking of the car 2. This step-by-step action design ensures the precise fit between the pin 122A and the pin positioning hole 2A, which not only facilitates the smooth insertion of the pin 122A, but also forms a reliable mechanical lock after lifting, further improving the safety and stability of the mechanism operation.

[0054] In some examples, for each pin assembly 122, the square head 1222 of the pin 122A in the pin assembly 122 can be connected to the pin shaft 1221 in an integrally formed structure to improve the overall structural strength and fatigue durability. The cross-sectional shape of the aforementioned fixing groove 12221 is designed to be rectangular, trapezoidal, or dovetail-shaped, which, together with the corresponding protrusion structure 2B on the inner wall of the pin positioning hole 2A, enhances the stability of the limiting engagement and prevents disengagement under long-term vibration conditions.

[0055] In some embodiments, such as Figures 1 to 12As shown, each latch assembly 122 may further include a proximity switch 122G and a proximity switch plate 122H. In each latch assembly 122, the proximity switch 122G is installed at the end of the latch head 1222, and the proximity switch plate 122H is disposed on the car 2 at a position corresponding to the latch positioning hole 2A. It is used to receive the signal from the proximity switch 122G so as to determine whether the latch 122A is extended into place or fully inserted into the latch positioning hole 2A based on the signal interaction between the proximity switch 122G and the proximity switch plate 122H, thereby ensuring that the car 2 is reliably fixed.

[0056] In practical applications, for each latch assembly 122, when the latch head 1222 of the latch assembly 122 is fully inserted into the corresponding latch positioning hole 2A and in place, the proximity switch 122G of the latch assembly 122 corresponds to the position of the proximity switch plate 122H. The proximity switch plate 122H receives the signal from the proximity switch 122G to confirm that the latch is correctly locked. This signal can be transmitted to the control system as the basis for judging the locking status of the car 2, ensuring the safety of subsequent operations. If the proximity switch plate 122H does not receive the signal from the proximity switch 122G, it is determined that the latch 122A is not in place, and the system will prohibit lifting or lateral movement, effectively preventing the risk of misoperation and further improving the automation level and safety reliability of the device.

[0057] Furthermore, in specific implementation, such as Figure 11 and Figure 12 As shown, for each pin assembly 122, the pin 122A of the pin assembly 122 may be provided with a proximity switch cable hole 122I for the proximity switch 122G cable to pass through. The proximity switch cable hole 122I extends axially along the pin 122A to the end of the pin square head 1222, ensuring that the proximity switch 122G cable is reliably connected to the external control system after passing through the pin 122A, and avoiding cable exposure causing wear or interference.

[0058] 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). Furthermore, as... Figures 1 to 12As shown, the lifting and pin telescopic device 10 includes two lifting and pin telescopic device units 200. These two lifting and pin telescopic device units 200 (i.e., the first lifting and pin telescopic device unit 200A and the second lifting and pin telescopic device unit 200B) are symmetrically arranged on the mounting frame 100 along the lifting direction of the car 2. In each lifting and pin telescopic device unit 200, the pin telescopic mechanism 12 includes two pin components 122. These two pin components 122 are symmetrically arranged on both sides of the second drive unit 121 and are linked with the pin connecting plate 123 through two synchronous fixing blocks 122B to ensure consistent operation.

[0059] Accordingly, the operation process of the aforementioned 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.

[0060] (2) Upward to downward transition step: 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 weight imbalance on both sides of the traction machine when the car 2 is subjected to subsequent force conversion. Then, the two lifting and pin extension device units 200 included in the car lifting and pin extension device 10 work simultaneously, so that the pins 122A of the four pin components 122 in the car lifting and pin extension device 10 are synchronously inserted into the corresponding pin positioning holes 2A on both sides of the car under the drive of the second drive unit 121. At the same time, the lifting frames of the two lifting mechanisms in the car lifting and pin extension device 10 are also lifted. 111 Under the drive of the first drive unit 112, the four pin assemblies 122 are lifted a certain distance to ensure that the pin square heads 1222 at the ends of the four pin assemblies 122 engage with the protruding structures 2B on the inner wall of the pin positioning holes 2A on both sides of the car 2, thus fixing the car 2. After the car 2 is fixed by the four pin assemblies 122, the lifting frame 111 of the two lifting mechanisms in the car lifting and pin extension device 10 continues to lift the four pin assemblies 122 under the drive of the first drive unit 112, so that the four pin assemblies 122 drive the car 2 to move upward synchronously. As the car 22 is lifted synchronously, the shaft connected to the car 2 and The traction ropes, initially taut, gradually slacken until the weight of the car 2 is entirely borne by the four pin assemblies 122. At this point, both lifting and pin telescopic device units 200 simultaneously stop lifting, and the traction ropes in both the ascending and descending hoists are unloaded. Then, the unhooking mechanism in the ascending hoist causes the traction ropes in the ascending hoist to detach from the car 2. The translation drive device 20 drives the car lifting and pin telescopic device 10 and the car 2 as a whole to move horizontally to the top of the descending hoist. At this point, the translation drive device stops working. Subsequently, the unhooking mechanism in the descending hoist connects the traction ropes in the descending hoist to the car 2, and the car lifts... The lifting frame 111 of the two lifting mechanisms in the lifting and pin telescopic device 10 lowers the four pin assemblies 122 under the drive of the first drive unit 112. The four pin assemblies 122 first descend synchronously with the car 2 for a certain distance. After the weight of the car 2 is completely borne by the traction rope connected to the car 2 in the descending shaft, the four pin assemblies 122 continue to descend until the pin square heads 1222 at the ends of the four pin assemblies 122 are completely disengaged from the protruding structures 2B in the pin positioning holes 2A on both sides of the car. Then, the four pin assemblies 122 retract synchronously under the action of the second drive unit 121, disengaging from the pin positioning holes 2A, allowing the car 2 to descend, thus completing the rail change.

[0061] (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.

[0062] (4) Downward to Upward Transition Step: After the car 2 travels 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 weight imbalance on both sides of the traction machine during subsequent force conversion of the car 2. Then, the two lifting and pin extension device units 200 included in the car lifting and pin extension device 10 work simultaneously, so that the pins 122A of the four pin components 122 in the car lifting and pin extension device 10 are synchronously inserted into the corresponding pin positioning holes 2A on both sides of the car under the drive of the second drive unit 121. At the same time, the lifting frames of the two lifting mechanisms in the car lifting and pin extension device 10 are also lifted. 111 Under the drive of the first drive unit 112, the four pin assemblies 122 are lifted a certain distance to ensure that the pin square heads 1222 at the ends of the four pin assemblies 122 engage with the protruding structures 2B on the inner wall of the pin positioning holes 2A on both sides of the car 2, thus fixing the car 2. After the car 2 is fixed by the four pin assemblies 122, the lifting frame 111 of the two lifting mechanisms in the car lifting and pin extension device 10 continues to lift the four pin assemblies 122 under the drive of the first drive unit 112, so that the four pin assemblies 122 drive the car 2 to move upward synchronously. As the car 22 is lifted synchronously, the shaft connected to the car 2 and The traction ropes, initially taut, gradually slacken until the weight of the car 2 is entirely borne by the four pin assemblies 122. At this point, both lifting and pin telescopic device units 200 simultaneously stop lifting, and the traction ropes in both the ascending and descending hoists are unloaded. Then, the disengagement mechanism in the descending hoist causes the traction ropes in the descending hoist to detach from the car 2. The translation drive device 20 drives the car lifting and pin telescopic device 10 and the car 2 to move horizontally to the bottom of the ascending hoist. At this point, the translation drive device stops working. Subsequently, the disengagement mechanism in the ascending hoist connects the traction ropes in the ascending hoist to the car 2, and the car lifts. Under the drive of the first drive unit 112, the lifting frame 111 of the two lifting mechanisms in the pin telescopic device 10 lowers the four pin assemblies 122, so that the four pin assemblies 122 first descend synchronously with the car 2 for a certain distance. After the weight of the car 2 is completely borne by the traction rope connected to the car 2 in the descending shaft, the four pin assemblies 122 continue to descend until the pin square heads 1222 at the ends of the four pin assemblies 122 are completely disengaged from the protruding structures 2B in the pin positioning holes 2A on both sides of the car. Then, under the action of the second drive unit 121, the four pin assemblies 122 retract synchronously, disengage from the pin positioning holes 2A, and allow the car 2 to descend, thus completing the rail change.

[0063] As can be seen from the above, the car lifting and pin telescopic device provided in this embodiment is applied to a circulating elevator translation and track changing system. The circulating elevator translation and track changing system includes an elevator vertical shaft, a car, and a translation drive device. When the car is inside the elevator vertical shaft, it can be raised and lowered by the traction rope inside the elevator vertical shaft and move to the highest or lowest floor. The car lifting and pin telescopic device is configured to fix and lift the car when it moves to the highest or lowest floor, so that the traction rope is in an unloaded state. The translation drive device is configured to drive the car lifting and pin telescopic device and the car as a whole to move horizontally after the car lifting and pin telescopic device fixes and lifts the car. Furthermore, the car lifting and pin telescopic device includes a mounting frame and multiple lifting and pin telescopic device units. The multiple lifting and pin telescopic device units are symmetrically arranged on the mounting frame along the car lifting direction, and each lifting and pin telescopic device unit... Each retraction device unit includes a lifting mechanism and a pin telescopic mechanism. The lifting mechanism is configured to lift the car when it reaches the highest or lowest floor. The pin telescopic mechanism is configured to fix the car and bear its weight during the lifting process. This allows the car to be lifted and fixed by the lifting and pin telescopic mechanism when it moves to the highest or lowest floor under the traction of the traction rope inside the elevator shaft. This leaves the traction rope unloaded, allowing the car's weight to be transferred from the traction rope to the translational track-changing mechanism. This ensures the stability and safety of the car during the translational track-changing process, effectively solving the problem in existing circulating elevators where the lack of a force conversion device to transfer the car's weight from the traction rope to the translational track-changing mechanism during vertical shaft switching results in compromised safety and smooth comfort during car operation.

The circulating elevator translational track-changing system includes an elevator vertical shaft and a car 2. When the car 2 is inside the elevator vertical shaft, it can be raised and lowered and moved to the highest or lowest floor under the traction of the traction rope inside the elevator vertical shaft. Furthermore, the translational track-changing mechanism includes a car lifting and pin telescopic device 10 and a translational drive device 20, as described in any of the above embodiments. The car lifting and pin telescopic device 10 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. The translational drive device 20 is configured to drive the car lifting and pin telescopic device 10 and the car 2 to move horizontally as a whole after the car lifting and pin telescopic device 10 fixes and lifts the car 2.

[0068] Specifically, the circulating elevator translation and track changing system may also include an elevator vertical shaft and a car 2, and when the car 2 is inside the elevator vertical shaft, it can be raised and lowered and moved to the highest or lowest floor under the traction of the traction rope inside the elevator vertical shaft.

[0069] Furthermore, the translational track-changing mechanism includes the car lifting and pin telescopic device 10 and the translational drive device 20 of any of the above embodiments.
