Detailed Implementation
[0026] The present invention will be further described in detail below with reference to specific embodiments.
[0027] like Figures 1-8As shown, this embodiment provides a bidirectional lateral moving three-dimensional parking garage based on rolling helical transmission, comprising: a parking garage frame 1, which includes a first parking frame 11 and a second parking frame 12, the first parking frame 11 and the second parking frame 12 being spaced apart and parallel to each other, and each of the first parking frame 11 and the second parking frame 12 having multiple parking spaces 13, the parking spaces 13 of the first parking frame 11 corresponding to the parking spaces 13 of the second parking frame 12; a bidirectional lateral moving mechanism 3, which includes a first-direction vehicle-carrying moving component 32 and a second-direction vehicle-carrying moving component 31, the first-direction vehicle-carrying moving component 32 being disposed on the second-direction vehicle-carrying moving component 31, the first-direction vehicle-carrying moving component 32 being able to carry a vehicle to move towards the first parking frame 11, and the second-direction vehicle-carrying moving component 31 being able to drive the first-direction vehicle-carrying moving component 32 to carry a vehicle to move towards the second parking frame 12; and a lifting mechanism 2, which is able to drive the second-direction vehicle-carrying moving component 31 to move in the horizontal and vertical directions. Specifically, the lifting mechanism 2 is located between the first parking rack 11 and the second parking rack 12. The lifting mechanism 2 can move in the area enclosed between the first parking rack 11 and the second parking rack 12. The lifting mechanism 2 can drive the bidirectional lateral movement mechanism 3 and the car parked on the bidirectional lateral movement mechanism 3 to rise and fall between the first parking rack 11 and the second parking rack 12. The first direction vehicle moving component 32 can carry the car to move towards the first parking rack 11. The second direction vehicle moving component 31 can drive the first direction vehicle moving component 32 to carry the car to move towards the second parking rack 12, respectively parking the car in the parking space of the first parking rack and the second parking rack.
[0028] The lifting mechanism 2 includes a horizontal moving mechanism, a lifting mechanism, and a fixed vehicle platform 27. The lifting mechanism is mounted on the horizontal moving mechanism, and the fixed vehicle platform 27 is slidably connected to the lifting mechanism. The lifting mechanism is used to drive the fixed vehicle platform 27 to move in the height direction. The second direction vehicle moving component 31 is mounted on the fixed vehicle platform 27.
[0029] The horizontal movement mechanism includes a fixed frame 21, wheel sets 22, and a first drive motor 23. There are two fixed frames 21, which are spaced apart and parallel to each other. There are four wheel sets 22, with two wheel sets 22 rotatably connected to both ends of each fixed frame 21. There are two first drive motors 23, which are respectively connected to two wheel sets 22 located on different fixed frames 21.
[0030] The lifting mechanism includes four columns 20, a drum 24, a wire rope 26, guide wheels 29, pulley blocks 2822, crossbeams, and second drive motors 25. There are four columns 20, with two columns 20 fixedly connected to both ends of each fixed frame 21. The columns 20 are vertically arranged relative to the fixed frame 21. There are two crossbeams, with both ends of each crossbeam fixedly connected to the tops of two columns 20 on the same fixed frame 21. There are two pulley blocks 2822 and two guide wheels 29, with two pulley blocks 2822 respectively located at one end of two crossbeams, and two guide wheels 29 respectively located at the other ends of two crossbeams. There are two second drive motors 25. Two drive motors 25 are fixed on two columns 20 respectively. The output shaft of each second drive motor 25 is connected to a reducer. There are four drums 24. The output shaft of each reducer is connected to two drums 24 to form a double drum 24. There are four wire ropes 26. One end of each of the four wire ropes 26 is wound around two double drums 24. The other end of one wire rope 26 of the same double drum 24 passes through the pulley block 2822 and the guide wheel 29 in sequence and is fixedly connected to one end of the fixed platform 27. The other end of the other wire rope 26 of the same double drum 24 passes through the pulley block 2822 and is fixedly connected to the other end of the fixed platform 27. Specifically, four uprights 20 are rectangularly distributed on two fixed frames 21. A crossbeam is connected to the top of the two uprights 20 on the same fixed frame 21. That is, the crossbeam, the fixed frame 21 and the two uprights 20 form a rectangular structure. The other ends of the four steel wire ropes 26 are fixedly connected to the four corners of the fixed platform 27. When the two double rollers rotate, the four steel wire ropes 26 are simultaneously wound up or unwound, so that tension can be applied to the four corners of the fixed platform 27 at the same time, ensuring that the fixed platform 27 is subjected to uniform force.
[0031] In this embodiment, the lifting mechanism employs two drums 24 to lift the fixed vehicle platform 27. Specifically, a single drive motor drives both drums 24 in synchronized motion, and each drum 24 in turn drives two steel wire ropes 26 for lifting. A second drive motor 25 uses a reducer to reduce speed and increase torque. Two drums 24 are positioned at the output shaft of the reducer, each controlling a steel wire rope 26, which in turn controls the lifting of both ends of the vehicle platform. When moving left and right during vehicle storage or retrieval, a large torsional torque is generated. Using a single column 20 could easily cause tipping accidents. Therefore, safety is improved by adopting a lifting method with two columns 20 on each side and four steel wire ropes 26 linked together, which significantly enhances safety performance.

[0033] The first-direction vehicle-carrying moving assembly 32 includes a first roller track 322, a first roller connecting angle steel 324, a first-direction vehicle-carrying plate 321, a first lead screw 326, a first lead screw bearing seat 327, and a first lead screw slider 328. Multiple first roller tracks 322 are distributed at intervals on the second-direction vehicle-carrying plate 311. Multiple first roller connecting angle steels 324 are also present, each rotatably connected to a first roller 323. The multiple first rollers 323 are respectively connected to multiple first roller tracks 326. 2. Rolling connection: Multiple first roller connecting angle steels 324 are fixedly connected to the bottom of the first direction vehicle plate 321; there are two first lead screw bearing seats 327, which are fixed at intervals on the second direction vehicle plate 311; the two ends of the first lead screw 326 are rotatably connected to the two first lead screw bearing seats 327 respectively; one end of the first lead screw 326 is connected to a fourth drive motor 325; the first lead screw slider 328 is threadedly connected to the first lead screw 326; and the bottom of the first direction vehicle plate 321 is fixedly connected to the first lead screw slider 328.
[0034] The first-direction vehicle moving assembly 32 and the second-direction vehicle moving assembly 31, through the cooperation of the lead screw and lead screw slider, and the cooperation of the roller and roller track, ensure that the frictional energy consumption of the first-direction vehicle moving assembly 32 and the second-direction vehicle moving assembly 31 is small, the transmission efficiency is high, and the operation is smooth and without shaking. There is no crawling even at low operating speeds. Depending on the application, when a suitable pre-tightening installation method is selected, better position control accuracy can be obtained.
[0035] The parking spaces 13 of the first parking rack 11 and the second parking rack 12 have the same structure.

The support assembly is used to support the car.
[0036] The support assembly includes a first support rod and comb teeth 14. There are two first support rods, which are fixed to both sides of the first parking frame 11. There are multiple comb teeth 14, which are divided into four groups.

In terms of construction, they have a short construction period, can be built quickly, and do not cause dust or other pollution.
