Description

Technical Field

[0001] This utility model relates to a three-dimensional parking device, and more particularly to an integrally mobile three-dimensional parking device suitable for cantilever beam parking platforms. Background Technology

[0002] Most current multi-level parking platforms are four-corner supported single-level platforms. These platforms have high construction costs and occupy a large space. Their corresponding multi-level parking devices are equipped with clamping, lifting, lateral movement and steering mechanisms, which are not only more complex in structure, but also have more transmission components and higher costs. The newly emerging cantilever beam parking platform has the advantages of occupying less space and having lower construction costs, but it is not suitable for existing multi-level parking devices. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned shortcomings of the existing technology by providing an integrated mobile three-dimensional parking system. It is not only simple in structure, low in cost, and reliable, but also highly efficient in operation and has a wide range of applications, and can be applied to cantilever beam parking platforms.

[0004] To achieve the above objectives, this utility model provides an integrated mobile three-dimensional parking device, comprising two parallel bottom beams, a front column and a rear column fixedly connected to each bottom beam, and both the front and rear columns connected by a fixed crossbeam; characterized in that: both the front and rear columns are connected to steering wheels; each of the opposite sides of the front and rear columns has a set of movable columns in the same group via longitudinal guide rails, and the two movable columns in the same group are fixedly connected by a lower crossbeam and an upper crossbeam; a dual-output reducer is fixedly connected to the middle of each bottom beam, the input shaft of the dual-output reducer is connected to a motor, and the two output shafts of the dual-output reducer are sequentially connected to their respective couplings, 90-degree shaft connectors, and longitudinal lead screws; the upper ends of the two longitudinal lead screws are connected to bearings on the fixed crossbeam, and a bearing cooperating with its respective lead screw is fixed on the lower crossbeam. Two nuts; a moving crossbeam is connected to the upper crossbeam and the bottom beam through a longitudinal traction connection mechanism. The moving crossbeam is equipped with two moving arm mechanisms. Each of the two moving arm mechanisms includes a horizontal slide rail fixed to the moving crossbeam and a reducer, a slider that cooperates with the horizontal slide rail, and a housing fixed to the slider. The input shaft of the reducer is connected to the drive motor, and the output shaft of the reducer is connected to the horizontal lead screw. Nuts that cooperate with the horizontal lead screw are fixed on the housing. A reducer is fixed in the housing and a horizontal transmission shaft and two longitudinal rotating shafts are fixed in the housing. The reducer motor is connected to the transmission shaft through a belt pulley mechanism. Two worm gears with opposite rotation directions are provided on the transmission shaft. Worm wheels that mesh with their respective worm gears are fixed on the two rotating shafts. Arms are fixed to the lower end of each rotating shaft.

[0005] The aforementioned longitudinal traction connection mechanism can be two sprockets fixed to the upper crossbeam and two chains wound around their respective sprockets in the middle, with the two ends of the chains fixed to the moving crossbeam and the bottom beam, respectively.

[0006] The aforementioned longitudinal traction connection mechanism can also consist of two pulleys fixed to the upper crossbeam and two steel wire ropes wound around their respective pulleys in the middle, with the two ends of the steel wire ropes fixed to the moving crossbeam and the bottom beam, respectively.

[0007] This utility model allows for arbitrary movement via four steering wheels. Two drive motors adjust the relative positions of two boxes on the same side of the moving crossbeam. Each box, via a reduction motor, pulley mechanism, worm gear, and meshing worm wheel, enables the two arm clamps to grip or release the wheels. It can be used on vehicles with different wheelbases, making it widely applicable. A motor, dual-output reducer, coupling, and 90-degree shaft connector drive two longitudinal lead screws to rotate. Matching nuts move the lower crossbeam, two moving columns, and the upper crossbeam—forming a single-sided frame that moves up and down. A longitudinal traction connection mechanism then drives the moving crossbeam to move synchronously up and down, enabling vehicle lifting or lowering and parking on the cantilever beam parking platform. The lifting distance of the moving crossbeam is twice that of the single-sided frame, resulting in high operational efficiency. Furthermore, the absence of a steering mechanism makes its structure simple and cost-effective. The worm gear and worm wheel meshing has a self-locking function, ensuring reliable wheel clamping.

[0008] As a further improvement of this utility model, both the front and rear pillars are connected to a steering wheel via a shock-absorbing connecting seat. The shock-absorbing connecting seat includes a support fixed to the front or rear pillar, an upper fixed block and a lower fixed block fixed to the support, two guide pillars slidingly passing through the upper and lower fixed blocks, and a clamp with both ends fitted around the two guide pillars between the upper and lower fixed blocks and fixed to the two guide pillars. Springs are provided on the guide pillars between the upper fixed block and the two ends of the clamp, and the clamp is fixed to the steering wheel. During the movement of the steering wheel, if it encounters an obstacle, the shock-absorbing connecting seat can buffer and dampen the shock, improving the safety and reliability of the vehicle during the transfer process.

[0009] As a further improvement of this utility model, the front and rear columns of each bottom beam are fixedly connected to the side connecting rods by top reinforcing ribs, and the side connecting rods are fixedly connected by several transverse connecting rods; this can improve the load-bearing strength of the device.

[0010] In summary, this utility model not only has a simple structure, low cost, and good reliability, but also high operating efficiency and wide range of applications, and can be applied to cantilever beam parking platforms. Attached Figure Description

[0021] like Figures 1 to 9As shown, the integrated mobile three-dimensional parking device of this embodiment includes two parallel bottom beams 1, a front column 2 and a rear column 3 fixedly connected to each bottom beam, and the front column 2 and the rear column 3 are both connected by a fixed crossbeam 4; the front column 2 and the rear column 3 are both connected to a steering wheel 5 through a shock-absorbing connecting seat, the shock-absorbing connecting seat includes a support 6 fixed to the front column 2 or the rear column 3 by several bolts, an upper fixed block 7 and a lower fixed block 8 fixed to the support 6, two guide columns 9 slidingly passing through the upper fixed block 7 and the lower fixed block 8, and a clamp 10 with both ends sleeved on the two guide columns 9 between the upper fixed block 7 and the lower fixed block 8 and fixed to the two guide columns, and springs 11 are provided on the outside of the two guide columns 9 between the upper fixed block 7 and the two ends of the clamp 10. 5. Fixed connection; The front column 2 and the rear column 3 are respectively equipped with a set of movable columns 13 on the opposite side of the longitudinal guide rail pair 12. The two movable columns 13 in the same group are fixedly connected by the lower crossbeam 14 and the upper crossbeam 15; A double output reducer 16 is fixedly connected to the middle of the bottom beam 1. The input shaft of the double output reducer 16 is connected to the motor 17. The two output shafts of the double output reducer 16 are respectively connected to their respective couplings 18, 90-degree shaft connectors 19 (or 90-degree right angle transmission boxes) and longitudinal lead screws 20 in sequence. The upper ends of the two longitudinal lead screws 20 are connected to the bearings on the fixed crossbeam 4. Two nuts 21 that cooperate with their respective longitudinal lead screws 20 are fixed on the lower crossbeam 14; A movable crossbeam 22 is connected by longitudinal traction. The mechanism is connected to the upper crossbeam 15 and the bottom beam 1. This longitudinal traction connection mechanism includes two sprockets 23 fixed to the upper crossbeam 15 and two chains 24 wound around their respective sprockets 23 in the middle. The two ends of the chains 24 are fixed to the moving crossbeam 22 and the bottom beam 1, respectively. Both ends of the moving crossbeam 22 are provided with moving arm mechanisms. Each moving arm mechanism includes a horizontal slide rail 26 fixed to the moving crossbeam 22 and a reducer 28, two sliders 27 cooperating with the horizontal slide rail 26, and a housing 32 fixed to the two sliders 27. The input shaft of the reducer 28 is connected to the drive motor 29, and the output shaft of the reducer 28 is connected to the horizontal lead screw 30. The housing 32 is fixed with a component that cooperates with the horizontal lead screw 30. The housing 32 is equipped with a nut 31; a geared motor 33 is fixedly mounted inside the housing 32 via a mounting bracket 36, and a horizontal drive shaft 34 and two longitudinal rotating shafts 35 are mounted on the bearings inside the mounting bracket 36. The geared motor 33 is connected to the drive shaft 34 via a pulley mechanism 37. The drive shaft 34 is equipped with two worm gears 38 with opposite directions of rotation. The two rotating shafts 35 are fixedly connected with worm wheels 39 that mesh with their respective worm gears 38. The lower end of each rotating shaft 35 is fixedly connected with a retaining arm 40, and a support plate 41 fixedly connected to the housing is provided below the retaining arm 40. The front column 2 and rear column 3 of each bottom beam 1 are fixedly connected to the lateral connecting rod 43 via a top reinforcing rib 42. The two lateral connecting rods 43 are fixedly connected by several transverse connecting rods 46.

[0022] This utility model allows for arbitrary movement of four steering wheels 5, facilitating the placement of two bottom beams 1 on either side of a vehicle and, after clamping the vehicle, moving it above a cantilever beam parking platform for three-dimensional parking. Two drive motors 29 adjust the relative positions of the two boxes 32 on the same side of the moving crossbeam 22. The two clamping arms 40 on each box 32 correspond to the positions of their respective wheels. A reduction motor 33 and a pulley mechanism 37 drive the transmission shaft 34 to rotate forward or backward. Because the two worm gears 38 rotate in opposite directions, the worm gears 38 mesh with the worm wheel 39, causing the two clamping arms 40 to clamp or release the wheels. Two sets of clamping arms 40 on the same bottom beam 1 can clamp the front and rear wheels on the same side, making it suitable for vehicles with different wheelbases and offering a wide range of applications. Figure 4 As shown, the dual-output reducer 16, coupling 18, and 90-degree shaft connector 19 can drive the two longitudinal lead screws 20 to rotate. Through the mating nuts 21, they can drive the frame composed of the lower crossbeam 14, two movable columns 14, upper crossbeam 15, lateral connecting rod 43, and transverse connecting rod 45 to move upward. When the upper crossbeam 15 moves upward, its two fixed sprockets 23 drive the movable crossbeam 22 to move upward synchronously through two chains 24, which can lift the vehicle onto the cantilever beam parking platform. The entire vehicle can be moved by the four steering wheels 5. The device places the vehicle directly above the cantilever beam parking platform, then lowers the moving crossbeam 22 appropriately and releases the two sets of clamping arms 40 to complete the three-dimensional parking. Since one end of the chain 24 is fixed to the bottom beam 1, the lifting distance of the moving crossbeam 22 driven by one end is twice the lifting distance of the frame, which has high operating efficiency and can reduce the height of the longitudinal screw 20. In addition, there is no need for a steering mechanism, so its structure is relatively simple and low cost. The worm 38 and worm wheel 39 have a self-locking function to ensure the reliability of clamping the wheel.

[0023] During the movement of the steering wheel 5, if it encounters an obstacle, the shock absorption connecting seat can buffer and absorb the shock through the spring 11, thereby improving the safety and reliability of the vehicle during the transfer process; the frame composed of the lateral connecting rod 43 and several transverse connecting rods 46 can improve the load-bearing strength of the device, and the support plate 41 can improve the support strength of the clamping arm 40 clamping the tire.

[0024] This utility model is not limited to the above-described embodiments. For example, the longitudinal traction connection mechanism can also be replaced by two pulleys and two steel wire ropes wound around their respective pulleys in the middle. The two ends of the steel wire ropes are respectively fixed to the moving crossbeam and the bottom beam, which can also achieve high lifting efficiency. The lifting mechanism consisting of motor 17, dual output reducer 16, coupling 18, 90-degree shaft connector 19, longitudinal lead screw 20, and two mating nuts 21 can be replaced by hydraulic cylinder or electric lifting rod. The pulley mechanism 37 can be replaced by sprocket and chain mechanism. They are all equivalent technology replacements.
