The lifting plate 1 can be used for lifting the vehicle carrying plate in each three-dimensional parking space, the vehicle carrying plate is moved into the parking space through the transverse moving device of the three-dimensional garage after being lifted to the target position, and for the three-dimensional garage without the vehicle carrying plate, the lifting plate 1 can also be directly used for lifting the vehicle, and the vehicle is lifted to the height of the target parking space and then is driven into the parking space by a driver. The fixed point can be a fixed part on the garage frame, and can also be a fixed seat arranged on the ground or a fixed object near the garage frame. The first sling rope 21, the second sling rope 22, the third sling rope 23 and the fourth sling rope 24 can be connected with the fixed point 3, or can be combined into a steel rope and then connected with the fixed point 3, when the first sling rope 21, the second sling rope 22, the third sling rope 23 and the fourth sling rope 24 simultaneously pass around the driving pulley 2, the driving pulley 2 can select a four-groove pulley, when the first sling rope 21, the second sling rope 22, the third sling rope 23 and the fourth sling rope 24 are combined into a sling and pass around the driving pulley 2, the driving pulley 2 can select a single-groove pulley. The driving screw rod 4 can be fixedly arranged on the garage frame or on the ground or a fixed object near the garage frame, and the driving pulley 2 on the driving nut 6 can be used for realizing traction of each sling. The fixed pulleys for guiding and reversing each sling can be arranged by a person skilled in the art according to the actual installation position of the driving screw rod 4 and the actual structure of the garage frame, and are not necessary structures, so that the fixed pulleys are not shown in the attached drawings. When the driving screw rod 4 is arranged on the top of the garage frame, the invention basically does not need a fixed pulley for reversing and guiding, and the length of a sling used is shortest, the cost is lowest, and the resistance is smallest, so that the driving screw rod 4 is generally preferably arranged on the top of the garage frame except for a small number of areas with limited space or terrain. The driving nut 6 of the present invention is always subjected to the drag force by the weight of the elevating plate 1, and thus does not rotate together with the driving screw 4, and in order to enhance the stability of the driving nut in the lateral movement, the present invention may be provided with a guide such as a guide rail on one side of the driving nut 6 in the lateral movement direction thereof. The invention adopts the mode that the lead screw and the nut drag the pulley to drag the sling, can reduce the response time of starting and stopping the lifting plate, occupies smaller three-dimensional space, and is more beneficial to improving the space utilization rate of the three-dimensional garage. When the invention is used, as shown in fig. 2, when the stroke of the driving pulley 2 is L, the lifting plate 1 can be driven to complete a lifting stroke 2 times that of L, so that the lifting speed of the lifting plate can be effectively increased, and the waiting time for storing and taking the three-dimensional vehicles can be shortened.

On the basis of the basic scheme, the invention can realize more functions by increasing the number of the driving pulleys 2, and the specific technical scheme is as follows:

the number of the driving pulleys 2 is at least 2, the rotating shaft 7 of each driving pulley 2 is connected with a driving structure consisting of a set of independent driving motor 5, a driving screw rod 4 and a driving nut 6, and when each sling is wound around each driving pulley 2, the sling is wound around the adjacent driving pulleys 2 in an S shape from different sides of the two adjacent driving pulleys 2. This scheme is through the stack multiunit power pulley 2, realizes whole lifter plate 2 promotion in step. Because the length of conventional single parking space stereo garage frame is generally more than 7 meters (can satisfy basically that most domestic vehicles deposit), when drive lead screw 4 was installed at garage frame top, the stroke of power pulley 2 generally can reach 5 meters, and multiunit drive lead screw 4 sets up side by side at garage frame top, all can realize the stroke more than 5 meters.

The following example of the travel of the power pulley 2 being 5 meters and the height of the single-layer parking space being 2.5 meters introduces the superimposed effect of the multiple groups of power pulleys 2:

when the number of the power pulleys 2 is 2, a 9-storey stereo garage with the total height of 20 meters of the parking space can be served, and as shown in fig. 3, each sling is simultaneously S-shaped to pass by from different sides of the two driving pulleys 2. When the 1-layer parking spaces are used for storing and taking vehicles or taking and placing vehicle carrying plates, the lifting plate 1 is lowered to the ground without lifting; when the vehicle is stored and taken out or the vehicle carrying plate is taken and placed in the vehicle parking positions of 2-9 layers, the lifting of the lifting plate 1 is realized by simultaneously moving the two driving pulleys 2, for example: when the vehicle is stored and taken out or the vehicle carrying plate is taken out and put in the parking spaces of the 2-layer parking spaces, the two driving motors 5 simultaneously drive the driving pulley 2 to move 625mm, so that the lifting plate 1 can realize 4 times of displacement, namely 2.5 meters. When 3 layers of parking spaces parking stall access vehicle or get and put and carry the sweep, two driving motor 5 drive pulley 2 simultaneously and remove 1250mm, can make lifter plate 1 realize 4 times's displacement, 5 meters … … analogizes with this promptly, and when two driving motor 5 drove drive pulley 2 simultaneously and remove 5 meters, lifter plate 1 can realize 20 meters of maximum stroke. Above-mentioned drive mode can promote the lifting speed of lifter plate 1, reduce response time by a wide margin to driving motor 5's power can be halved, is favorable to promoting the efficiency of access car, reduces the garage cost.

When the number of power pulleys 2 is 3, the ropes are passed around the two adjacent drive pulleys 2 in an S-shape simultaneously from different sides of the two adjacent drive pulleys 2. The driving mode is basically the same as that when the number of the power pulleys 2 is 2, the lifting plate 1 can realize 6 times of displacement, the number of the storage spaces which can be served can be increased to 13 layers, 6 times of displacement can be realized, and the power of the driving motor 5 can be reduced to 1/3. The lifting speed of the lifting plate 1 can be further improved, the response time is shortened, the vehicle storing and taking efficiency is improved, and the garage cost is reduced.

When the number of the power pulleys 2 is 4, 5 or more, the number of the parking spaces which can be served is more, but in order to avoid the over-high speed of the lifting plate 1 and divide the power pulleys 2 into groups, every 2 or 3 power pulleys 2 are divided into one group, the driving mode of each group of power pulleys 2 is the same as that when the number of the power pulleys 2 is 2 or 3, and each group of power pulleys 2 completes the whole stroke of the lifting plate 1 in a segmented mode. For example, when the number of the power pulleys 2 is 5, the power pulleys can serve 21 layers of three-dimensional garages, two power pulleys 2 are divided into a group, and the group serves for vehicle storage and taking of 1-9 layers of parking spaces or vehicle carrying plate taking and placing; the other 3 power pulleys 2 are divided into a group to serve the vehicle storage and taking of the 10-21-layer storage spaces or the vehicle carrying plate taking and placing. When the target parking space is on the 1-9 layers, only the first group of power pulleys 2 simultaneously transversely move to drive the lifting plate 1 to lift, when the target parking space is on the 10 layers or more than 20 layers, the first group of power pulleys 2 drive the lifting plate 1 to lift to the 9 layers, then the second group of power pulleys 2 are simultaneously started to drive the lifting plate 1 to move to the height of the target parking space.

In order to further reduce the occupied space of the driving device and improve the space utilization rate, the driving motors 5 on the adjacent driving screw rods 4 can be respectively arranged at different ends of the respective driving screw rods 4. This structure can make the 4 compact settings of multiunit drive lead screw, and occupation space still less can set up more multiunit drive lead screw 4 in limited space such as garage frame top.
