The utility model discloses in the direction of each hoist cable, the switching-over is with fixed pulley can be set up by the actual structure of driving screw 4 actual mounted position and garage frame by technical personnel in the field, not necessary structure, consequently the utility model discloses an do not embody in the drawing. When drive lead screw 4 is installed at garage frame top, the utility model discloses need not set up basically and be used for the switching-over and the fixed pulley of direction, and used hoist cable length is the shortest, the cost is the lowest, the resistance is the minimum, consequently except that the limited region in a small number of spaces or topography, generally first-selected will drive lead screw 4 installs at garage frame top. Driving nut 6 receives the tractive force that lifter plate 1's weight brought all the time, consequently can not be along with the same rotation of drive lead screw 4, stability when for strengthening its sideslip, the utility model discloses also can driving nut 6 one side sets up guides such as guide rail along its sideslip direction. The utility model discloses a hoist cable is pull to the mode that lead screw, nut pull the pulley, can reduce the response time that the lifter plate starts and stops to it is less to occupy the cubical space, more does benefit to the space utilization who promotes stereo garage. The utility model discloses during the use, as shown in fig. 2, when 2 strokes of drive pulley are L, can drive lifter plate 1 and accomplish 2 times of lift stroke of L, consequently can effectively promote the lifting speed of lifter plate, shorten three-dimensional garage stock, the latency when getting the vehicle.

The utility model discloses on the basis of above-mentioned basic scheme, more functions are realized to the quantity that the accessible increases drive pulley 2, and concrete technical scheme is as follows:

the number of the driving pulleys 2 is at least 2, the respective rotating shaft 7 of each driving pulley 2 is connected with a driving structure consisting of a set of independent driving motor 5, a set of independent driving screw rod 4 and a set of independent driving nut 6, and when each sling is wound around each driving pulley 2, different sides of the two driving pulleys 2 are wound in an S shape between the 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.

When the number of the power pulleys 2 is 2-3, the driving pulleys 2 move simultaneously to realize the lifting of the lifting plate 1, the total number of layers of the garage is N, the number of layers to be moved is M, and the maximum stroke of each driving pulley 2 is L, so that the distance L1 of the simultaneous movement of each driving pulley 2 is obtained according to the following formula when the lifting plate 1 is lifted each time:

when the number of the power pulleys 2 is more than 3, the power pulleys 2 are grouped, 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 the power pulleys 2 of each group complete the whole stroke of the lifting plate 1 in a segmented mode.

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, the garage can serve 9 layers of three-dimensional garages with the total height of 20 meters of parking spaces, and as shown in fig. 3, each sling is S-shaped and bypasses 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 the power pulleys 2 is 3, each sling is S-shaped between the adjacent driving pulleys 2 to pass by different sides of the two driving 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.

The utility model discloses a further reduce drive arrangement's space area occupied, promote space utilization, can install driving motor 5 on the adjacent drive lead screw 4 respectively at the different ends of separately driving lead screw 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.
