Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a parallel pit multistage parking apparatus that can park a large number of automobiles in a small area.
[0002]
[Prior art]
Parking facilities are an indispensable facility for recently built apartment buildings. However, apartment buildings built in the city often do not have enough land. For this reason, a parking apparatus that parks cars in two stages is used.
[0003]
[Problems to be solved by the invention]
Since such two-stage parking apparatus can be parked in one parking space, it is effective in saving space, but an apparatus capable of parking more cars in a small area is required. In addition, since such a parking device is a burden on the individual who purchases the apartment house, a low-priced one is required. For this reason, a simple device such as an automobile lifting device is also required.
[0004]
This invention is made | formed in view of this problem, and it aims at providing the parking apparatus which can park many motor vehicles in a narrow area. Moreover, it aims at providing the parking apparatus which raises / lowers a motor vehicle with a comparatively simple apparatus.
[0005]

When the first main shaft (11a) is rotationally driven, the second main shaft (11b) is also rotationally driven through the rotation transmission device, whereby the first, second, third and fourth The lowermost floor is raised or lowered via the main sprocket, the first and second chains, and the first, second, third and fourth auxiliary sprockets .
[0006]
By storing two cars in a row on one floor and stacking a plurality of floors, many cars can be parked in a small area. Since each floor can be stopped at the ground level, a car can be stored in each stage, and a car can be easily delivered from each stage. The top car is at the ground level, and the other car is stored in the underground pit, so it is highly resistant to strong winds and earthquakes and has a good appearance.
[0008]
When the rotary drive device is rotated, the first main shaft is rotated, and the second main shaft is also rotated in the reverse direction by the rotation transmission device. Accordingly, the first main sprocket, the first sub sprocket, the third sub sprocket, the first chain hung on the third main sprocket, the second main sprocket, the second sub sprocket, the second The second chain hung on the four sub sprockets and the fourth main sprocket is wound up or down depending on the rotation direction of the first main shaft. As a result, the lowermost floor connected to the sub sprocket moves up and down. Since all the parking shelves are attached to the lowermost floor, the parking shelves can be raised and lowered. By operating the rotary drive device so that the floor of each shelf is stopped at the ground level, it is possible to load and unload vehicles on each floor. Moreover, since all the parking shelves can be raised and lowered with one rotary drive device, it is a simple device.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a plan view of the parking apparatus of the present embodiment. Reference numeral 30 denotes a high-rise apartment house, which is a so-called high-rise apartment. Reference numeral 31 denotes a parking facility provided in the site of the high-rise apartment house 30. The parking facility is composed of a plurality (six in the figure) of parking units 32, and this parking unit 32 is the column pit multistage parking apparatus of the present invention. The automobile 1 enters and exits each parking unit 32 along a route indicated by an arrow.
[0010]
FIG. 2 is a cross-sectional view taken along the line XX of FIG. FIG. 3 is a cross-sectional view taken along the line YY of FIG. The parking shelf 3 is formed by stacking three floors 4 in accordance with the height of the automobile 1 and joining them with shelf columns 5. Two cars 1 are stored in each floor 4 in tandem. The two automobiles 1 are stopped at predetermined positions by car stops 6 provided on each floor 4. One pit 2 is provided for the entire parking facility 31. The pit 2 is dug in the ground and the inner surface is finished with concrete, and the depth of the pit 2 is deep enough to be one step lower than the number of steps of the parking shelf 3. That is, the uppermost floor 4 is at the ground level, and the uppermost automobile 1 is stored at the same height as parked on the ground. An underground strut 7 is provided in the pit 2 and supports a lifting device 10 that lifts and lowers the parking shelf 3.
[0011]
FIG. 4 is a three-dimensional view of the lifting device. In the lifting device 10, two main shafts 11a and 11b are arranged in parallel with the floor 4 interposed therebetween. An intersecting shaft 12 having bevel gears 13 at both ends is provided at the ends of the main shafts 11a and 11b, and the bevel gears 13 that mesh with the main shafts 11a and 11b at corresponding positions are also provided. Main sprockets 14a, 14b, 14c, and 14d are fixed to the front and rear ends of the main shafts 11a and 11b, and rotate integrally with the main shafts 11a and 11b. A driven sprocket 18 is fixed to the main shaft 11a, and the main shaft 11a is rotated by this rotation. A drive sprocket 19 is connected to the driven sprocket 18 via a chain 21, and the drive sprocket 19 is directly connected to the electric motor 20.
[0012]
Four sub-shafts 15 are provided at the front and rear ends in parallel with the main shafts 11a and 11b at the lower part of the lowermost floor 4, and sub sprockets 16a, 16b, 16c and 16d are provided at the tips of the sub-shafts 15. . A chain 17 is hung on the main sprocket 14a, sub sprocket 16a, sub sprocket 16c, and main sprocket 14c as shown in the figure. Similarly, the main sprocket 14b, sub sprocket 16b, sub sprocket 16d, and main sprocket 14d are also shown in the figure. Chain 17 is hung. The parking rack 3 shown in FIG. 2 is integrated with the bottom floor 4. The main shafts 11 a and 11 b are rotatably attached to the underground strut 7 by bearings, and the electric motor 20 is attached to a support base attached to the underground strut 7.
[0013]
Next, the operation of the driving device 10 will be described.
When the electric motor 20 is rotated, the drive sprocket 19 is rotated and the driven sprocket 18 is rotated via the chain 21. As a result, when the main shaft 11 a rotates, the main shaft 11 b also rotates through the intersecting shaft 12. The rotation directions of the two main shafts 11a and 11b are opposite to each other as shown in FIG. When both the main shafts 11a and 11b rotate, the chain 17 is wound up or down, and the auxiliary sprockets 16a, 16b, 16c and 16d are moved up or down while rotating. Thereby, the floor 4 can be raised / lowered. In the case of the rotation direction of the main shafts 11a and 11b shown in FIG. 4, the chain 17 is wound up and the floor 4 is raised. Thus, the floor 4 can be raised or lowered by changing the rotation direction of the electric motor 20. Moreover, by stopping when the position of each floor 4 of the parking shelf 3 reaches the ground level, the automobile 1 can be loaded into and unloaded from the floor 4.
[0014]
The parking shelf 3 described above has a case where six cars are parked in the case of three tiers, but if it is two tiers, it becomes four, and if it is four tiers, eight can be parked.
[0015]
【The invention's effect】
As described above, the present invention is a space for two cars, which is twice the number of floors, by raising and lowering a parking shelf having a plurality of floors in which two cars can be parked in a row in the pit. Can be stored. The parking shelf lifting device is a simple device that combines a shaft, sprocket, and gears, so it can be manufactured at low cost.
