Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional garages, and in particular to a movable double-layer three-dimensional parking garage. Background Art

[0002] With the acceleration of the urbanization process, the parking demand in densely populated areas (such as shopping malls, hospitals, office buildings, etc.) is increasing day by day. However, the space of underground parking lots is limited and it is difficult to meet the increasing vehicle parking demand. In order to improve the utilization rate of parking spaces, three-dimensional garages (especially double-layer mechanical parking equipment) are widely used in underground parking lots, effectively increasing the parking capacity by means of double-layer parking.

[0003] However, the existing three-dimensional garages have the following technical problems in actual use:

[0004] 1. The carrier frame of the three-dimensional garage usually requires the vehicle to reverse into it. However, the environment of the underground parking lot is dimly lit and the vision is limited. It is difficult for the driver to accurately judge the positional relationship between the vehicle and the carrier frame, and often needs to adjust the direction multiple times to complete the reverse parking into the garage, resulting in low efficiency.

[0005] 2. Since the width and length of the carrier frame are only slightly larger than the vehicle size, during the reverse parking process, if care is not taken, it is easy to cause the vehicle to scrape or collide with the columns, guardrails or other structures of the carrier frame, which not only affects the parking safety, but may also damage the vehicle or garage equipment.

[0006] 3. When storing and retrieving vehicles, additional dispatching space is required, which will cause waste of space resources.

[0007] Therefore, there is an urgent need for a technical solution that can optimize the reverse parking process of the three-dimensional garage to improve the parking efficiency, reduce the collision risk and enhance the user experience. Summary of the Invention

[0008] To solve the technical problems in the background art, the present invention discloses a movable double-layer three-dimensional parking garage.

[0009] The present invention provides a movable double-layer three-dimensional parking garage, including a parking rack and a liftable car carrier. At the lower end of the parking rack, there are a driving steering wheel, a steering wheel, a driving wheel and a driven wheel whose positions form a rectangle;

[0010] The driving steering wheel and the steering wheel are located close to the aisle;

[0011] The driving steering wheel and the driving wheel are driven by a straight-line reduction motor installed on the parking rack and move along the direction of the driving steering wheel and the driving wheel;

[0012] The driving steering wheel and the steering wheel are driven to rotate by a steering reduction motor installed on the parking rack;

[0013] The driven wheel is rotatably connected to the parking rack, so that when the parking rack rotates, the directional position of the driven wheel remains unchanged;

[0014] The parking rack successively undergoes operations of going straight to the aisle, rotating a certain angle around the driven wheel, and the car-carrying plate descending to the ground, so that the vehicle can drive onto the car-carrying plate in a forward manner.

[0015] Furthermore, it also includes a guide rail; the driven wheel is snap-connected to the guide rail; when the parking rack moves, the driven wheel remains snap-connected to the guide rail.

[0016] Furthermore, the driven wheel includes two rows of guide wheels; the guide rail is provided with two parallel and spaced-apart guide bars; each row of guide wheels is respectively snap-connected to a guide bar.

[0017] Furthermore, the active steering wheel and the driving wheel are respectively located in front of and beside the driven wheel.

[0018] Furthermore, an arc-shaped limiting groove arranged horizontally is provided on the parking rack; both the active steering wheel and the steering wheel are provided with limiting rods arranged vertically and snap-connected to the limiting groove.

[0019] Furthermore, it also includes a chain assembly driven by a lifting and decelerating motor; the chain assembly leads out fixed chains fixing the four corners of the car-carrying plate; the lifting and decelerating motor drives the fixed chains to lift and lower synchronously.

[0020] Furthermore, a hook is also provided on the parking rack; a hanger is provided on the car-carrying plate; when the car-carrying plate rises, the hanger is snap-connected to the hook.

[0021] Furthermore, the hanger snaps onto or disengages from the hook through rising and falling actions in sequence.

[0022] Furthermore, the hanger is located directly below the hook part of the hook; the hook is hinged to the parking rack through a hinge shaft, and the opening of the hook part of the hook faces upward; the hinge shaft is also hinged to one end of a weight rod, and a weight contacting the hook is provided at the other end of the weight rod; the weight freely hangs down under the action of gravity and drives the hook to rotate downward.

[0023] Furthermore, an automatic disengaging frame is connected to the hook; the automatic disengaging frame is provided with a plurality of rotationally symmetric connecting arms; the structure of the connecting arms is configured as follows: when the hanger needs to disengage from the hook and perform a rising action, one of the connecting arms is inclined upward, and its upper end abuts against the lower end of the weight, and the other connecting arm is inclined downward to close the groove of the hook.

[0024] The beneficial effects of the present invention are:

[0025] 1. Through the coordinated drive of the active steering wheel, steering wheel and reduction motor, the parking rack can move flexibly and adjust the angle, enabling the car-carrying plate to automatically move to the aisle position and descend to the ground. The vehicle can drive directly forward onto the car-carrying plate without reversing into the garage, significantly reducing the operation difficulty and avoiding the risk of collision with structures such as columns and guardrails, which not only protects the vehicle appearance but also extends the service life of the garage equipment; it is especially suitable for underground parking lots with dim light and limited space, greatly shortening the parking time.

[0026] 2. The ground is directly below the car-carrying plate. When the vehicle in the lower layer is parked in reverse, it can be directly parked on the ground directly below the car-carrying plate without height difference, making it easier to park.

[0027] 3. The space below the car-carrying plate, on both sides of the parking rack and the ground forms the lower vehicle parking space. This space is wider, with more margin, and the tolerance space for reversing into the garage is also larger, making it less likely to collide.

[0028] 4. When the parking rack rotates, the driven wheel serves as the center of rotation of the parking rack, and its position and direction remain unchanged. In this way, the driven wheel plays a positioning role, making the position accuracy of the parking rack higher when it is reset.

[0029] 5. The active steering wheel and the active wheel are arranged diagonally, making the driving force received by the parking rack more uniform, and there will be no phenomenon of local stress causing the parking rack to be distorted and deformed.

[0030] 6. When parking or retrieving a vehicle, only this three-dimensional parking garage needs to be operated, without involving other three-dimensional parking garages and without affecting other parked vehicles, saving time and reducing energy consumption.

[0031] 7. One three-dimensional parking garage corresponds to one ground parking space, and there is no need to reserve a position for dispatching like traditional three-dimensional garages. Therefore, the number of ground parking spaces can be doubled in this invention, and the utilization rate is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0052] The present invention will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0053] As Figure 1 and Figure 2 shown, the present invention discloses a movable double-deck stereo parking garage, including a parking rack 1 and a liftable vehicle-carrying plate 2. The top of the parking rack 1 is a rectangular and horizontally arranged top rack, and the top rack is equipped with a lifting deceleration motor 10 and a chain assembly to drive the lifting of the vehicle-carrying plate 2. Its specific structure is: As Figures 6 - 9As shown in the figure, a horizontally arranged rotating shaft 102 is installed on the same side of the top frame as the lifting reduction motor 10 and above the lifting reduction motor 10. The driving end of the lifting reduction motor 10 drives the rotation of the rotating shaft 102 through chain drive. First sprockets 103 are installed at both ends of the rotating shaft 102, and two rotatably connected second sprockets 104 are installed on the top frame on the opposite side of the rotating shaft 102. The first sprockets 103 and the second sprockets 104 on the same side are at the same height and are linked by a clamped annular chain 105. The chain assembly further includes four L-shaped lifting chains, and the corners thereof are limited by clamped steering sprockets 106. The vertical part of the lifting chain is set as a fixed chain 11, and the lower end of the fixed chain 11 is fixedly connected to the side of the car carrier plate 2. The horizontal part of the lifting chain is set as a connecting chain 107, and the connecting chain 107 extends towards the annular chain 105. The two connecting chains 107 on the same side as the annular chain 105 are respectively fixedly connected to the upper and lower sides of the annular chain 105. The positions of the four fixed chains 11 form a rectangle and are evenly arranged on the side of the car carrier plate 2. With such a setting, when the lifting reduction motor 10 is started, the four fixed chains 11 can achieve synchronous lifting, and driven by one lifting reduction motor 10, their synchronism is higher and the cost is lower.

[0054] Rotating guide wheels 21 are also installed on the car carrier plate 2, and vertically arranged guide plates 17 are installed on the legs. The guide plates 17 are C-shaped steels, and the guide wheels are clamped in the grooves of the C-shaped steels to realize the lifting guidance of the car carrier plate 2, improve the stability of the lifting of the car carrier plate 2, and are not prone to shaking.

[0055] Four hooks 12 are also arranged on the top frame, and the positions of the four hooks 12 form a rectangle and are evenly arranged relative to the car carrier plate 2. The upper ends of the hooks 12 are hinged to the top frame, the hook parts are located at the lower ends of the hooks 12, and the grooves of the hooks 12 face upwards. Hook members 13 corresponding to the hooks 12 are evenly arranged on the car carrier plate 2. The hook members 13 are U-shaped with the opening facing downwards and are in the same vertical direction as the grooves of the hooks 12. When the hook members 13 need to be clamped with the hooks 12 to achieve the purpose of preventing the car carrier plate 2 from falling, first drive the hook members 13 to rise until they abut against the lower sides of the hook members 13. The lower sides of the hook members 13 are inclined, and their heights decrease from the hook parts to the roots; when the hook members 13 continue to rise, under the guiding action of the lower side surfaces of the hook members 13, the hook members 13 rotate away from the hook parts; when the hook members 13 continue to rise until they are separated from the hooks 12, the hooks 12 reset under the action of gravity. At this time, the hook members 13 are located directly above the grooves of the hooks 12; finally, drive the hook members 13 to descend, and the hook members 13 can be stably clamped on the hooks 12. With such a setting, when the car carrier plate 2 parks the vehicle in the upper parking space in the air, the car carrier plate 2 is fixed by clamping the hook members 13 with the hooks 12, which can avoid the risk of the car carrier plate 2 falling. At the same time, during this process, the lifting reduction motor 10 and the chains are not stressed, so that the lifting reduction motor 10 and the chains are not easily damaged and their service life is extended.

[0056] The hook 12 is hinged to the top frame through a hinge shaft 14, and a weight rod 15 is also hinged to this hinge shaft 14; the upper end of the weight rod 15 is hinged, and a weight 151 is arranged at the lower end, and the weight 151 abuts against the outer side wall of the hook 12 in the horizontal direction. With such an arrangement, the weight 151 swings freely downward under the action of gravity, and can also push the hook 12 to swing downward, so that when the hook 12 swings upward to a certain height and its gravity is difficult to overcome the resistance and it is difficult to swing downward stably, it can obtain the thrust of the weight 151 and rotate downward stably. As Figure 3 shown, a through groove is provided at the central position of the hook 12, dividing the hook 12 into two symmetrical parts, which are set as hook plates; the upper ends of the hook plates are fixedly connected by a welded connecting plate, and the inner sides of the lower ends are fixedly connected by a welded partition plate. The upper ends of the hook plates are all sleeved on the hinge shaft 14. The upper part of the weight rod 15 is inserted between the hook plates, and the weight 151 at the lower part is located outside the hook plates, and the weight 151 is of a symmetrical structure, and its two ends respectively abut against one hook plate, so that the hook 12 is evenly stressed.

[0057] In this embodiment, the hook 13 can also be automatically disengaged from the hook 12 through the ascending and descending actions in sequence. To achieve this action, the specific structure is as follows: As Figures 20 - 24 shown, an automatic disengagement frame 16 is installed at the middle position between the hook plates, and the middle part of the automatic disengagement frame 16 is rotationally connected to the hook 12. The automatic disengagement frame 16 is also provided with a plurality of rotationally symmetric connecting arms 161. In this embodiment, the number of the connecting arms 161 is four forming a "cross" shape, which are sequentially set as the first connecting arm 1611, the second connecting arm 1612, the third connecting arm 1613 and the fourth connecting arm 1614. When the hook 13 is latched to the hook 12, the first connecting arm 1611 is located directly above the hook 13, the second connecting arm 1612 is located near the weight 151, and the third connecting arm 1613 is located below the hook 12. When the hook 13 needs to disengage from the hook 12, as Figures 17 - 20As shown, first drive the hook 13 to rise, and push the first connecting arm 1611 to rotate upward. At this time, the second connecting arm 1612 abuts against the weight 151 and drives the weight 151 to rotate upward. When the hook 13 rises to the position where the upper end of the second connecting arm 1612 abuts against the lower end of the weight 151, the third connecting arm 1613 rises to the position where it closes the opening of the groove of the hook 12 and forms a downwardly inclined state. Subsequently, drive the hook 13 to descend. At this time, the second connecting arm 1612 is obliquely upward, and the direction of the force exerted by the weight 151 on the second connecting arm 1612 coincides with the extension direction of the second connecting arm 1612. Therefore, the second connecting arm 1612 and the weight 151 are in a state of force balance and are fixed to each other. When the hook 13 abuts against the upper end of the third connecting arm 1613 and continues to descend, it will push the hook 12 and the automatic disengaging frame 16 to rotate away from the hook part of the hook 12 at the same time; when the hook 13 continues to descend, it can automatically disengage from the hook 12. When the hook 13 disengages from the hook 12, the hook 12 automatically resets under the combined action of its own gravity and the weight 151.

[0058] Four legs that are vertically led out downward from the vertex position of the top frame and whose positions form a rectangle are respectively installed with a driving steering wheel 3, a steering wheel 4, a driving wheel 5, and a driven wheel 6 at their lower ends. The driving steering wheel 3 and the steering wheel 4 are located near the aisle.

[0059] The driving steering wheel 3 is driven by a straight-line reduction motor 7 and moves along the direction of the driving steering wheel 3; the driving steering wheel 3 is also driven to rotate by a steering reduction motor 8, and its specific structure is: as Figures 10 - 13As shown in the figure, the lower end of the outrigger is fixedly connected with an upper support 108. The upper support 108 is in a box structure with an open upper end, and the open end is fixedly connected with the lower end of the outrigger. The steering reduction motor 8 is installed inside the upper support 108, and its driving end is equipped with a driving gear 109. The lower end of the upper support 108 is connected with a motor box 111 through a slewing bearing 110. The upper support 108 is fixedly connected with the inner ring of the slewing bearing 110, and the motor box 111 is fixedly connected with the outer ring of the slewing bearing 110. The outer ring of the slewing bearing 110 is also provided with a driven gear 112 that meshes with the driving gear 109. In this way, when the steering reduction motor 8 is started, the motor box 111 can be driven to rotate. Since the parking rack 1 also needs to rotate by 90°, only one end of the driven gear 112 is set as an arc, and its central angle is also set to 90°. To avoid the driving gear 109 and the driven gear 112 from disengaging due to errors, in this embodiment, the central angle of the driven gear 112 is preferably 120°, which can ensure that the driving gear 109 and the driven gear 112 do not disengage, and can also reduce costs and the load on the steering reduction motor 8. To prevent the steering reduction motor 8 from over-steering due to incorrect quality or damage, an arc-shaped limiting groove 101 is also opened at the bottom of the upper support 108. The upper end surface of the outer ring of the slewing bearing 110 is threadedly connected with a limiting rod 31 that extends upward and inserts into the limiting groove 101. The limiting rod 31 is limited by both ends of the limiting groove 101 to ensure the accurate steering angle of the parking rack 1.

[0060] A straight-line reduction motor 7 and a wheel rack 113 are installed on the motor box 111. The driving steering wheel 3 is installed on the wheel rack 113, and the straight-line reduction motor 7 drives the driving steering wheel 3 to roll through a chain drive.

[0061] The driving wheel 5 is driven by the straight-line reduction motor 7 and rolls along the direction of the driving wheel 5. Its specific structure is: the lower end of the outrigger is fixedly installed with a motor box 111. A straight-line reduction motor 7 and a wheel rack 113 are installed on the motor box 111. The driving wheel 5 is installed on the wheel rack 113, and the motor drives the driving wheel 5 to roll through a chain drive.

[0062] The steering wheel 4 is driven to rotate by a steering reduction motor 8. Its specific structure is as follows: The lower end of the support leg is fixedly connected with an upper support 108. The upper support 108 is in a box structure with an open upper end, and the open end is fixedly connected with the lower end of the support leg. The steering reduction motor 8 is installed inside the upper support 108, and a driving gear 109 is installed at its driving end. The lower end of the upper support 108 is connected with a wheel frame 113 through a slewing bearing 110. The upper support 108 is fixedly connected with the inner ring of the slewing bearing 110, and the wheel frame 113 is fixedly connected with the outer ring of the slewing bearing 110. An arc-shaped driven gear 112 that meshes with the driving gear 109 is also arranged on the outer ring of the slewing bearing 110. In this way, when the steering reduction motor 8 is started, the motor box 111 can be driven to rotate. Since the parking rack 1 also needs to rotate 90°, only one end of the driven gear 112 is set as an arc shape, and its central angle is also set to 90°. To avoid the driving gear 109 and the driven gear 112 from disengaging due to errors, in this embodiment, the central angle of the driven gear 112 is preferably 120°, which can ensure that the driving gear 109 and the driven gear 112 do not disengage, reduce costs, and reduce the load of the steering reduction motor 8. To prevent the steering reduction motor 8 from oversteering due to incorrect quality or damage, an arc-shaped limiting groove 101 is also opened at the bottom of the upper support 108. A limiting rod 31 that extends upward and is inserted into the limiting groove 101 is threadedly connected to the upper end surface of the outer ring of the slewing bearing 110. The limiting rod 31 is limited by both ends of the limiting groove 101 to ensure the accurate steering angle of the parking rack 1.

[0063] The driven wheel 6 is rotatably connected to the support leg. Its specific structure is as follows: As Figure 4 and Figure 5 shown, a slewing bearing 110 is connected between the support leg and the driven wheel 6. The lower end of the support leg is fixedly connected with the inner ring of the slewing bearing 110, and the upper end of the driven wheel 6 is fixedly connected with the outer ring of the slewing bearing 110. Guide rails 9 are installed on the ground of the parking garage, and the guide rails 9 extend along the straight-line direction of the parking rack 1. The driven wheel 6 is clamped with the guide rail 9; when the parking rack 1 moves, the driven wheel 6 remains in a clamped state with the guide rail 9. The specific clamping structure between the driven wheel 6 and the guide rail 9 is as follows: The driven wheel 6 includes two rows of guide wheels 61; the guide rail 9 is provided with two parallel and spaced-apart guide strips 91; each row of guide wheels 61 is respectively clamped with a guide strip 91. With such a setting, the support strength of the driven wheel 6 for the support leg is higher and more stable. The distance between the guide strips 91 is configured such that the active steering wheel 3 can just be clamped between the guide strips 91, which can also improve the moving accuracy of the active guide wheel 61. A limit switch 114 is also installed on the driven wheel 6, and a limit block 115 corresponding to the limit switch 114 is installed on the guide rail 9 at a position close to the aisle; when the parking rack 1 moves straight to a set distance, the limit block 115 triggers the limit switch 114 and controls the straight-line reduction motor 7 to stop, so as to improve the accuracy of the moving position of the parking rack 1.

[0064] The working principle of this embodiment is as follows:

[0065] S1. Start the straight-line reduction motor 7. As shown in Figure 14 the figure, move the parking rack 1 to the aisle. Under the action of the limit switch 114 triggered by the limit block 115, control the straight-line reduction motor 7 to stop;

[0066] S2. Start the steering reduction motor 8 to make the active steering wheel 3 and the steering wheel 4 rotate by a certain angle respectively; in this embodiment, the positions of the four legs form a square. Therefore, as shown in Figure 16 the figure, the active steering wheel 3 rotates 90°, and the steering wheel 4 rotates 45°;

[0067] S3. Start the straight-line reduction motor 7. As shown in Figure 15 the figure, make the parking rack 1 rotate with the driven wheel 6 as the center. The rotation angle range of the parking rack 1 is 70 - 90°, so as to ensure that the vehicle can drive steadily onto the loading board 2 when moving forward; in this embodiment, the rotation angle of the parking rack 1 is 90°;

[0068] S4. Start the lifting reduction motor 10 to drive the loading board 2 to descend to the ground;

[0069] S5. The vehicle drives straight forward onto the loading board 2;

[0070] S6. Start the lifting reduction motor 10 to drive the loading board 2 to rise to the set position, where the lower end surface of the loading board 2 is higher than the top of the vehicle;

[0071] S7. The parking rack 1 resets;

[0072] S8. Another vehicle enters the area below the loading board 2 by reverse parking to achieve double-vehicle parking.

[0073] In summary, the advantages of this embodiment are as follows:

[0074] 1. Through the coordinated drive of the active steering wheel 3, the steering wheel 4 and the reduction motor, the parking rack 1 can move flexibly and adjust the angle, so that the loading board 2 can automatically move to the aisle position and descend to the ground. The vehicle does not need to reverse into the garage and can directly drive forward onto the loading board 2, significantly reducing the operation difficulty and avoiding the risk of collision with structures such as columns and guardrails, which not only protects the vehicle appearance but also extends the service life of the garage equipment; it is especially suitable for underground parking lots with dim light and limited space, greatly shortening the parking time.

[0075] 2. The ground is directly below the loading board 2. When the vehicle in the lower layer is parked in reverse, it is directly parked on the ground directly below the loading board 2 without a height difference, making it easier to park;

[0076] 3. A vehicle parking space is formed below the loading board 2, on both sides of the parking rack 1 and the ground. This space is wider, with more margin, and has a larger error tolerance space for reverse parking, making it less likely to collide.

[0077] 4. When the parking rack 1 rotates, the driven wheel 6 serves as the center of rotation of the parking rack 1, and its position and direction remain unchanged. In this way, the driven wheel 6 plays a positioning role, and the guide rail 9 also limits the movement of the driving wheel and the active steering wheel 3, making the position accuracy of the parking rack 1 higher when it returns to its original position.

[0078] 5. The active steering wheel 3 and the driving wheel 5 are arranged diagonally, making the driving force received by the parking rack 1 more uniform, and preventing the phenomenon of local stress causing the parking rack 1 to be distorted.

[0079] 6. When parking or retrieving a vehicle, only this three-dimensional parking garage needs to be operated, without involving other three-dimensional parking garages and without affecting other parked vehicles, saving time and reducing energy consumption.

[0080] 7. One three-dimensional parking garage corresponds to one ground parking space, and there is no need to reserve a position for dispatching as in traditional three-dimensional garages. Therefore, the number of ground parking spaces can be doubled in this invention, and the utilization rate is greatly improved.

[0081] Based on the ideal embodiments of the present invention as described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
