Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of tower elevators, and in particular, to a circular tower elevator. Background Art

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the number of cars on the road is growing rapidly. This change has led to increasingly tight urban parking spaces and increasingly prominent parking challenges. Against this backdrop, multi-story parking garages, as a space-efficient parking solution, have garnered widespread attention and widespread promotion. Circular tower garage elevators, with their unique space utilization advantages and efficient vehicle access, have secured a prominent position in urban parking facilities.

[0003] The circular tower elevator uses a hoist to raise and lower the platform, transporting the vehicle to the designated parking height. The platform's transporter then moves the vehicle to the parking space. After parking, the transporter returns to the platform, and the elevator resets the platform, completing the entire parking process. This parking method effectively improves space utilization while providing users with a relatively convenient parking experience.

[0004] However, in actual use, the platform experiences an imbalanced force distribution as vehicles enter and exit the platform. When a vehicle enters, the force on the platform shifts toward the entrance; when a vehicle exits, the force on the platform shifts toward the exit. This imbalanced force, coupled with frequent and prolonged vehicle entry and exit, negatively impacts the platform's structural strength. Over time, the platform may experience localized deformation and structural fatigue, which not only reduces its service life but also poses safety risks.

[0005] Therefore, how to solve the problem of uneven force on the circular tower lift platform during the entry and exit of vehicles and enhance the structural strength and stability of the platform has become a key problem that urgently needs to be overcome in the current development of circular tower lift technology. Summary of the Invention

[0006] To overcome the above-mentioned defects, an embodiment of the present invention provides a circular tower elevator, which solves the technical problem in the related art that vehicles frequently enter and exit the platform, causing uneven force on the platform and affecting its strength.

[0007] According to one aspect, at least one embodiment of the present invention provides a circular tower elevator, comprising a lifting frame, a platform body, a module support plate, a weight sensing component, and a balancing counterweight, wherein the lifting frame is used to be connected to a lifting device and to be lifted and lowered under the drive of the lifting device, the platform body is rotatably mounted on the lifting frame, the module support plate is laid on the platform body along the length direction of the platform body, the weight sensing component is provided on both the inlet and outlet sides of the platform body, the weight sensing component is located below the module support plate, and the balancing counterweight is slidably mounted on the bottom surface of the platform body; The weight sensing component can collect the difference data of the weight borne by the module support plate on the inlet side and the outlet side, and transmit it to the controller of the power element that drives the balancing weight to slide, so that the balancing weight can be moved to the side with smaller weight when the difference data exceeds a preset value.

[0008] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: Four sets of guide rails are arranged on the infrastructure structure around the lifting frame, and the guide rails are arranged vertically. A set of sliders are arranged around each of the four sides of the lifting frame. The four sets of sliders slide on the four sets of guide rails respectively, and each set of sliders has two and are arranged vertically at intervals.

[0009] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: Four groups of positioning seats are also provided on the infrastructure structure around the lifting frame. Each group of positioning seats has multiple positioning seats and is arranged at vertical intervals. The positioning seats have positioning holes. Fixed guide sleeves are provided on all four sides of the lifting frame. Positioning plugs are slidably provided in the fixed guide sleeves. The four positioning plugs are used to be respectively inserted into the four positioning holes at the same height to position the lifting frame at that height.

[0010] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: Two sets of front wheel alignment wheels, a rear wheel alignment wheel set and a guide portion are symmetrically arranged along the central axis of the platform body; The front wheel alignment wheel set includes two rows of front alignment wheels rotatably arranged on the platform body, the two rows of front alignment wheels are parallel to each other and spaced apart, and are used to support and position the front wheels of the vehicle; The rear wheel alignment wheel set includes multiple rows of rear alignment wheels rotatably arranged on the platform body, the multiple rows of rear alignment wheels are parallel to each other and spaced apart, and are used to support and position the rear wheels of the vehicle through any two adjacent rows of the rear alignment wheels; The guiding parts are arranged to slide relative to the platform body, and the two groups of guiding parts can slide synchronously toward both sides of the platform body, abut against and push the inner sides of the vehicle tires, so that the vehicle is located on the central axis of the platform body.

[0011] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: The vehicle body further comprises a transport assembly, the transport assembly comprising a sliding frame, a lifting frame, a front wheel supporting bracket and a rear wheel supporting bracket, the sliding frame being slidably arranged on the platform body along the central axis of the platform body, the lifting frame being slidably arranged on the sliding frame, the front wheel supporting bracket and the rear wheel supporting bracket being slidably arranged on the lifting frame, the front wheel supporting bracket and the rear wheel supporting bracket being two groups and symmetrically arranged on both sides of the lifting frame, respectively used for lifting the front wheel and rear wheel of the vehicle, and the guide portion being provided on both the front wheel supporting bracket and the rear wheel supporting bracket.

[0012] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: The front wheel support bracket is provided with front wheel support comb teeth, which can be inserted under the front wheel of the vehicle at a position staggered from the front positioning wheel, so as to abut and lift the front wheel of the vehicle under the drive of the lifting frame; The rear wheel supporting bracket is provided with rear wheel supporting comb teeth, which can be inserted under the rear wheel of the vehicle at a position staggered from the rear positioning wheel, so as to abut and lift the rear wheel of the vehicle under the drive of the lifting frame.

[0013] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: The module support plate includes an entrance support plate, a middle support plate and an exit support plate, which are arranged in pairs and symmetrically distributed along the central axis of the platform body. The weight sensing component is arranged under the entrance support plate and the exit support plate. The entrance support plate, the rear wheel alignment wheel group, the middle support plate, the front wheel alignment wheel group and the exit support plate are arranged in sequence.

[0014] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: A lifting vehicle blocking plate is provided on the platform body for vertical sliding. The lifting vehicle blocking plate is located in front of the front wheel positioning wheel group and is used to block the front wheels of the vehicle so that the front wheels of the vehicle are stuck between the two rows of front positioning wheels. Limiting railings are provided on both sides of the platform body, and the limiting railings are used to limit the entry direction of the vehicle.

[0015] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: The platform body has a sliding groove in the direction of the central axis, and the sliding groove is used to accommodate the transport assembly.

[0016] For example, at least one embodiment of the present invention provides a circular tower elevator, further comprising: A running wheel and a guide wheel are rotatably provided on the sliding frame, the running wheel abuts against the bottom wall of the sliding groove, and the guide wheel abuts against the side wall of the sliding groove.

[0017] The beneficial effects of the embodiments of the present invention are: In the present invention, when a vehicle enters, the weight on the platform entrance side increases. If the weight difference between the two sides exceeds a preset value, it means that the force on the platform is significantly offset toward the entrance end, which may affect the structural strength and stability of the platform. At this time, the controller transmits an electrical signal to the power element that drives the balancing weight to slide. The power element drives the balancing weight to slide toward the platform exit side, thereby reducing the degree of force offset on both sides of the platform body and making the force on the platform as balanced as possible. Similarly, when a vehicle exits the platform, if the weight difference between the two sides exceeds a preset value, the controller controls the balancing weight to slide toward the entrance side to balance the force on the platform during the vehicle exit process.

[0018] By real-time monitoring of the weight difference between the platform's entrance and exit sides and adjusting the position of the balancing weight based on the difference, the force offset of the platform during vehicle entry and exit is effectively reduced, allowing the platform body to bear the vehicle's weight more evenly, avoiding local stress concentration caused by uneven force, thereby improving the platform's structural strength and stability.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0023] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

Therefore, it should not be understood as a limitation on the present invention.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 8 As shown, a circular tower elevator in one embodiment of the present invention includes a lifting frame 1, a platform body 2, a module support plate 3, a weight sensing assembly 4, and a counterweight 5. The lifting frame 1 is a component connecting the platform body 2 and the lifting equipment. The lifting equipment can be a traction machine or other form commonly used in the prior art. The platform body 2 is rotatably mounted on the lifting frame 1 via a slewing bearing, providing parking space for vehicles. The lifting frame 1 is equipped with a gear driven by a motor. The inner ring of the slewing bearing is fixedly connected to the lifting frame 1, and the outer ring gear meshes with the gear. The platform body 2 is mounted on the outer ring gear of the slewing bearing, thereby achieving rotation of the platform body 2.

[0029] The modular support plate 3 is laid on the platform body 2 along its length, and the counterweight 5 is slidably mounted on the bottom surface of the platform body 2. The counterweight 5 is slidably connected to the bottom surface of the platform body 2 via a combination of a guide rail 6 and a slider 7. The power element driving the sliding of the counterweight 5 is preferably a screw-nut mechanism. A motor mounted on the bottom surface of the platform body 2 drives the screw to rotate, and the screw threadedly engages with the nut structure on the counterweight 5 to drive the counterweight 5.

[0030] Weight sensing assemblies 4 are installed on both the inlet and outlet sides of the platform body 2, located beneath the module support plate 3. These are preferably pressure sensors. Each weight sensing assembly 4 comprises a sensing plate and a sensor connected to it. The sensing plate contacts the bottom of the module support plate 3, providing real-time data on the weight applied to the module support plate 3 at that location. The sensor converts the weight information collected by the sensing plate into an electrical signal, which is then transmitted to the controller of the power element that drives the sliding counterweight 5.

[0031] The weight sensing component 4 on the platform entrance side collects the weight information borne by the module support plate 3 on the entrance side in real time; at the same time, the weight sensing component 4 on the exit side also collects the weight information borne by the module support plate 3 on the exit side. When the difference in weight borne by the entrance side and the exit side exceeds a preset value, an electrical signal is transmitted to the controller.

[0032] When a vehicle enters, the weight on the platform's entrance increases. If the weight difference between the two sides exceeds a preset value, the platform's force is significantly offset toward the entrance, potentially affecting the platform's structural strength and stability. At this point, the controller transmits an electrical signal to the power element that drives the balancing weight 5 to slide. The power element drives the balancing weight 5 to slide toward the platform's exit, thereby reducing the degree of force offset between the two sides of the platform body 2 and maximizing the balance of forces on the platform. Similarly, when a vehicle exits the platform, if the weight difference between the two sides exceeds a preset value, the controller controls the balancing weight 5 to slide toward the entrance to balance the forces acting on the platform during the vehicle's exit.

[0033] By real-time monitoring of the weight difference between the platform's entrance and exit sides and adjusting the position of the balancing weight 5 according to the difference, the degree of force offset of the platform during the vehicle's entry and exit is effectively reduced, so that the platform body 2 can bear the vehicle's weight more evenly, avoiding local stress concentration caused by uneven force, thereby improving the structural strength and stability of the platform.

[0034] In some examples, such as Figure 1 、 4As shown in Figure 5, four groups of guide rails 6 are arranged vertically on the infrastructure structure around the lifting frame 1. A group of sliders 7 are arranged on each side of the lifting frame 1, and each group of sliders 7 contains two sliders, and the two sliders 7 are arranged at intervals along the vertical direction. Four groups of positioning seats 8 are also arranged on the infrastructure structure around the lifting frame 1, and each group of positioning seats 8 has multiple positioning seats, which are distributed at intervals along the vertical direction. The positioning seats 8 are set according to the heights of different parking spaces in the tower library to ensure that the lifting frame 1 has a corresponding positioning seat 8 for positioning when it reaches the height of each parking space. Fixed guide sleeves 9 are provided on all sides of the lifting frame 1, and the positioning plug 10 is slidably arranged in the fixed guide sleeve 9 to provide guidance for the positioning plug 10. The four positioning plugs 10 are respectively inserted into the four positioning holes 801 at the same height to position the lifting frame 1 at that height. The two ends of the electric push rod are respectively hinged on the lifting frame 1 and the positioning plug 10 to drive the positioning plug 10 to slide.

[0035] When lifting equipment (such as a traction machine) drives the hoist frame 1 to move upward or downward, the sliders 7 around the hoist frame 1 slide on the guide rails 6, providing a vertical motion trajectory, ensuring that the hoist frame 1 moves vertically up and down without deviation or tilt. The two sliders 7 in each set of sliders 7 are spaced vertically apart, ensuring that each side of the hoist frame 1 has two upper and lower contact points with the guide rails 6. This prevents shaking of the hoist frame 1 during the lifting process, thereby ensuring the stability of the platform body 2 during the lifting process and ensuring the safe lifting of the vehicle.

[0036] When the lifting frame 1 is raised to the designated parking space, the electric push rod is activated, extending the push rod and driving the hinged positioning insert 10 to slide within the fixed guide sleeve 9. The positioning insert 10 is inserted into the positioning hole 801 of the positioning seat 8 at the corresponding height. The lifting frame 1 is positioned at this height, facilitating the subsequent transport machine to move the vehicle to the parking space. When the vehicle is parked and the platform body 2 needs to be lowered, the electric push rod reverses its action, removing the positioning insert 10 from the positioning hole 801, and the lifting frame 1 continues to descend under the action of the lifting equipment.

[0037] In some examples, such as Figure 1 、 6As shown in Figures 7 and 8, the platform body 2 is the basic structure of the entire lifting platform. Two groups of front wheel alignment wheels 11 are symmetrically arranged along the central axis of the platform body 2. Each group of front wheel alignment wheels 11 includes two rows of front alignment wheels 1101 that are rotatably arranged on the platform body 2. The two rows of front alignment wheels 1101 are parallel to each other and spaced apart. They can adapt to the width of the vehicle's front wheels, allowing the vehicle's front wheels to be stuck between the two rows of front alignment wheels 1101, thereby playing a positioning role for the front wheels and preventing the front wheels from sliding during parking or adjusting the position of the vehicle. The rear wheel alignment wheels 12 are symmetrically arranged along the central axis of the platform body 2. Each group of rear wheel alignment wheels 12 includes multiple rows of rear alignment wheels 1201 that are rotatably arranged on the platform body 2. The multiple rows of rear alignment wheels 1201 are parallel to each other and spaced apart. When the vehicle is parked, the rear wheel is stuck between two adjacent rows of rear alignment wheels 1201 according to its wheelbase, achieving rear wheel positioning. The guiding portion 13 is slidably arranged relative to the platform body 2, and two groups are also symmetrically arranged along the central axis of the platform body 2. The two groups of guiding portions 13 can slide synchronously to both sides of the platform body 2, thereby abutting and pushing the inner side of the vehicle tire.

[0038] When a vehicle enters the lift platform, the driver maneuvers the front wheels between the two rows of front aligning wheels 1101 and positions the rear wheels between two adjacent rows of rear aligning wheels 1201, appropriately sized for the vehicle's wheelbase. At this point, the vehicle is initially positioned on the lift platform, but there may be lateral misalignment. The two sets of guides 13 are then caused to slide synchronously toward either side of the platform body 2. The guides 13 approach and abut the inner side of a tire on one side of the vehicle, applying thrust to the tire. During this process, the front and rear aligning wheels 1101, 1201 roll relative to each other, causing the entire vehicle to shift on the platform body 2. Because the two sets of guides 13 are symmetrically arranged along the central axis of the platform body 2 and slide synchronously outward, the vehicle can gradually move toward the central axis of the platform body 2 until each set of guides 13 abuts the inner wall of the tire on its corresponding side, at which point the vehicle reaches a centered position.

[0039] Through the front wheel alignment wheel set 11, the rear wheel alignment wheel set 12 and the guide part 13, the vehicle can be adjusted to the central axis of the platform body 2, so that when the vehicle is subsequently transported to the parking space, the parking accuracy in the parking space can also be guaranteed, ensuring that the mechanical parts are evenly stressed, extending the service life of the equipment, and improving the reliability and stability of the tower elevator.

[0040] In some examples, such as Figure 6 、 7As shown in Figure 8, the vehicle also includes a transport assembly 14, which comprises a sliding frame 1401, a lifting frame 1402, a front wheel support bracket 1403, and a rear wheel support bracket 1404. The sliding frame 1401 is slidably mounted on the platform body 2 along the central axis, providing basic support for the movement of the entire transport assembly 14. The lifting frame 1402 is slidably mounted on the sliding frame 1401. The front wheel support bracket 1403 and the rear wheel support bracket 1404 are both slidably mounted on the lifting frame 1402. There are two sets of these supports, symmetrically arranged on either side of the lifting frame 1402. The front wheel support bracket 1403 is used to lift the front wheels of the vehicle, while the rear wheel support bracket 1404 is used to lift the rear wheels of the vehicle. Both the front wheel support bracket 1403 and the rear wheel support bracket 1404 are equipped with a guide 13 for adjusting the vehicle's position during transport. During operation, the guide 13 abuts and pushes against the inner side of the tires to ensure the vehicle is centered.

[0041] The lifting frame 1402 can be raised and lowered by vertically arranging a rack on the lifting frame 1402 and arranging a gear driven by a motor on the sliding frame 1401, so that the gear drives the rack to move vertically, thereby realizing the lifting and lowering of the lifting frame 1402; the two sets of front wheel support brackets 1403 and rear wheel support brackets 1404 can be realized by installing a motor on the lifting frame 1402, the motor drives a gear, and racks are arranged on the support brackets on both sides, so that the two racks are respectively located on both sides of the gear and mesh with the gear, thereby realizing that the gear drives the support brackets on both sides to move toward or away from each other.

[0042] Once the lift platform reaches the designated parking height, the transport assembly 14 begins operation. First, the carriage 1401 slides along the central axis of the platform body 2, moving the front wheel support combs 1405 to a position offset from the two rows of front locating wheels 1101. Simultaneously, the rear wheel support combs 1406 move to a position offset from the multiple rows of rear locating wheels 1201. This ensures that the front and rear wheel support combs 1405, 1406 can be inserted under the vehicle tires without interfering with the front and rear locating wheels 1101, 1201.

[0043] The two sets of front wheel support brackets 1403 and rear wheel support brackets 1404 slide synchronously outward on the lifting frame 1402. During this sliding process, the guides 13 on the front wheel support brackets 1403 and rear wheel support brackets 1404 approach the inside of the vehicle tires, abutting and pushing against the inside of the tires, adjusting the vehicle's position and aligning it. Simultaneously, the front wheel support combs 1405 gradually insert under the vehicle's front wheels, staggered between the two rows of front aligning wheels 1101. The rear wheel support combs 1406 insert under the vehicle's rear wheels and into the gaps between the multiple rows of rear aligning wheels 1201.

[0044] After the vehicle's position is adjusted, the lifting frame 1402 rises. As the lifting frame 1402 rises, the front wheel support combs 1405 engage and lift the vehicle's front wheels, while the rear wheel support combs 1406 engage and lift the vehicle's rear wheels, thereby lifting the vehicle off the platform body 2. At this point, the vehicle is completely supported by the transport assembly 14. Next, the sliding frame 1401 slides, moving the transport assembly 14 carrying the vehicle above the parking space. Once the vehicle reaches the parking space, the lifting frame 1402 descends, placing the vehicle in the space. Finally, the sliding frame 1401 returns to its initial position on the platform body 2, completing the parking process. A comb structure can be provided on the parking space, interlaced with the front wheel support combs 1405 and rear wheel support combs 1406. This allows the vehicle to be loaded onto the comb structure above the parking space after the front wheel support combs 1405 and rear wheel support combs 1406 are lowered, enabling transfer.

[0045] During transport, the guides 13 on the front and rear wheel support brackets 1403 and 1404 adjust the vehicle's position, ensuring it remains centered during transport to the parking space, ensuring accurate parking and stability. The staggered arrangement of the front wheel support combs 1405 and front locating wheels 1101, and the staggered arrangement of the rear wheel support combs 1406 and rear locating wheels 1201, prevents interference between the support combs and the locating wheels during transport, ensuring smooth handling.

[0046] In some examples, such as Figure 6 As shown, the entrance support plates 301 are arranged in pairs and are symmetrically distributed on the entrance side of the platform body 2 along the central axis of the platform body 2. A weight sensing component 4 is provided below the entrance support plate 301 for real-time monitoring of the weight information borne by the entrance side when the vehicle enters. The middle support plates 302 are also arranged in pairs and are symmetrically distributed in the middle position of the platform body 2 along the central axis of the platform body 2 to provide a stable support force when the vehicle is traveling. The exit support plates 303 are arranged in pairs and are symmetrically distributed on the exit side of the platform body 2 along the central axis of the platform body 2. A weight sensing component 4 is also provided below the exit support plate 303 for real-time monitoring of the weight information borne by the exit side when the vehicle exits.

[0047] The modular support plate 3 is designed as an inlet support plate 301, a middle support plate 302 and an outlet support plate 303, and each support plate is spliced together by multiple separate plate modules. This modular design allows for individual treatment of specific support plate modules with problems during equipment maintenance and overhaul, without the need for large-scale repairs or replacements of the entire platform's support structure, reducing the difficulty and cost of maintenance.

[0048] In some examples, such as Figure 6 、 7As shown, the lifting and stopping plate 15 is vertically slidably arranged on the platform body 2, in front of the front wheel alignment wheel set 11. The lifting and stopping plate 15 can be raised and lowered by a telescopic member installed on the platform body 2, and can be raised and lowered by a screw-nut structure. The limiting railings 16 are arranged on both sides of the platform body 2 to limit the entry direction of the vehicle and ensure that the vehicle can travel in the direction defined by the limiting railings 16 when entering the platform body 2. The diagonal support rod 17 is arranged on the lifting frame 1 and is made of metal profiles. Its two ends are respectively connected to the top and bottom of the lifting frame 1 to form a triangular support structure, which improves the load-bearing capacity and stability of the lifting frame 1.

[0049] When a vehicle enters the lifting platform, the lifting stop plate 15 is in the raised state, extending out of the platform body 2. The vehicle enters the platform body 2 in the direction defined by the limit railing 16 to avoid being hit by the handling assembly 14 in the middle of the platform body 2. At this time, the lifting stop plate 15 plays a blocking and guiding role, helping the driver to clamp the front wheels of the vehicle between the two rows of front locating wheels 1101, and at the same time, clamp the rear wheels between two adjacent rows of rear locating wheels 1201 according to the vehicle wheelbase. Then the lifting stop plate 15 is lowered and retracted to avoid obstruction to the subsequent transfer operation of the vehicle.

[0050] The provision of a lifting stop plate 15 and a limiting rail 16 guides vehicles accurately into the vehicle and positions the front wheels between the two rows of front positioning wheels 1101, improving parking accuracy and ensuring more standardized parking on the platform body 2, while fully utilizing the platform space. The lifting frame 1 and the diagonal braces 17 work together to provide a stable support structure for the platform body 2. This triangular support structure enhances the stability of the platform body 2.

[0051] In some examples, such as Figure 6 As shown, a sliding groove 201 is provided along the central axis of the platform body 2 and extends along the length of the platform body 2. The sliding groove 201 is rectangular in shape, ensuring that the transport assembly 14 can be accommodated within the sliding groove 201. The sliding frame 1401 is rotatably provided with running wheels 1407 and guide wheels 1408. The running wheels 1407 are driven by a motor mounted on the sliding frame 1401 to achieve the movement of the sliding frame 1401, while the guide wheels 1408 are passively rotated.

[0052] The sliding groove 201 provides a storage space for the transport assembly 14. When the transport assembly 14 is not working, it can be stored in the sliding groove 201. When the vehicle enters the lifting platform, the risk of the transport assembly 14 protruding from the surface of the platform body 2 and scratching the vehicle chassis is avoided. The walking wheel 1407 abuts the bottom wall of the sliding groove 201, and plays the role of supporting and driving the sliding frame 1401. The guide wheel 1408 abuts the side wall of the sliding groove 201, and its function is to guide the sliding frame 1401 to move accurately along the direction of the sliding groove 201. During the sliding process of the sliding frame 1401, the guide wheel 1408 always maintains contact with the side wall of the sliding groove 201, ensuring that the transport assembly 14 slides along the central axis direction in the sliding groove 201, thereby improving the accuracy of the operation of the transport assembly 14.

[0053] The design of the sliding groove 201 to accommodate the handling assembly 14 prevents vehicles from rubbing against the handling assembly 14 when entering the lifting platform, improving safety during vehicle entry. The running wheels 1407 ensure smooth sliding of the sliding frame 1401, reducing vehicle sway and equipment vibration, and extending the service life of the equipment. The guide wheels 1408 cooperate with the side walls of the sliding groove 201 to guide the sliding of the sliding frame 1401, ensuring that the vehicle can be accurately placed in the parking space and improving the accuracy of vehicle handling.
