(See FIG. 1).

The elevating operation of each of the elevating posts 13 is simultaneously controlled by the operation of a hydraulic cylinder 16 as an actuator. The hydraulic cylinder 16 for lifting and lowering is
The telescopic rods 16a are vertically erected along the respective elevating posts 13. The ends of the telescopic rods 16a are connected to the respective elevating posts 13, and the lower ends of the cylinder portions 16b are connected to the lower ends of the post frames 12. It is. Each of the lifting posts 13 is provided with a vehicle lift (hereinafter simply referred to as a “ lift ”).
G ". ) 17 is supported in a cantilevered state, and the lifting operation of the lift 17 is guided.

The lift 17 is mounted on each of the lifting posts 13.
And two column-shaped vertical portions 18 are provided. These vertical portions 18 are connected to each other by a connecting member 18a extending in the left-right direction. As shown in FIG. 4, each of the vertical portions 18 is rotatably supported by a guide roller 20 which abuts on a guide surface 19 formed on each of the elevating posts 13 to roll. Wherein the lower position of the vertical portion 18, the carriage base body 8 with parallel horizontal portion 21 is firmly fixed. As a result, the lift 17 is substantially L-shaped when viewed from the left and right sides in the traveling direction of the bogie base body 8.

The lifting drive means of the lift 17 is as follows.

As shown in FIG. 3, each of the lifting posts 13
A lifting drive shaft 22 is rotatably mounted in the left-right direction between the upper end portions of the two. An elevating drive motor 24 with a speed reducer, which is rotatable in the forward and reverse directions, is fixed between the upper ends of the elevating posts 13 by using an appropriate bracket 23 using an appropriate bracket 23. This motor 2

It is connected to a vertical portion 18 of the lift 17.

In such a configuration, when the motor 24 is rotated in the winding direction of the chain 29, the lift 17 is pulled up via the chain 29.
Conversely, when the motor 24 is rotated in the unwinding direction of the chain 29, the lift 17 is lowered by its own weight.

In the drawing, reference numeral 30 denotes a balance weight connected to the other end 29b of each chain 29.

A turntable 31 for reversing the direction of the vehicle C on the lift 17 is provided on the horizontal portion 21 of the lift 17. This turntable 31
This is for enabling the vehicle C that has entered the vehicle forward to leave the vehicle forward. In the illustrated example, the direction of the vehicle C is reversed in advance before the vehicle C is stored in the parking space 4. The roller conveyor 7 is provided on the turntable 31.

Since the vehicle transport device 5 is configured as described above, the lift 17 can be raised in two stages. That is, the lift 17 is raised by one step by the operation of the motor 24 along the elevating post 13 which is retracted in the post frame 12. This is an ascending operation between the level of the first floor F1 and the level of the second floor F2. Further, along with the post frame 12, the lift 17 is raised by another step by the operation of the hydraulic cylinder 16 for driving up and down.
This is an ascending operation performed only in the vehicle entrance / exit space 3, and is used when the vehicle C is transferred to and from the ground GL. When the lift 17 rises in two stages, the lift 17 is higher than the upper end of the post frame 12 (see FIG. 1).

In the vehicle transport device 5 constructed as described above, when the vehicle C gets on the turntable 31 on the lift 17, the post-flagging occurs due to the load of the vehicle C. The deflection of the arm 12 may occur. Therefore, when not subjected whatsoever measures, data on the lift 17 - integrators - table 31 by tilting, is expected the risk of the vehicle C is dropped, where the onset
In order to correct the inclination of the turntable 31 due to the deflection of the post frame 12, the following configuration is adopted.

Each of the post frames 12 is attached to the bogie base 8 via a left-right pivot 32 so that the upper part thereof can be rotated in the front-rear direction (the running direction of the bogie base 8). I have. A hydraulic cylinder 33 as an actuator is provided between each of the post frames 12 and the bogie body 8. The hydraulic cylinders 33 automatically operate in synchronization with each other according to the degree of deflection generated in each of the post frames 12 when the vehicle C rides on the turntable 31, so that the turntable 31 is always horizontal. It acts to adjust the angle between each of the post frames 12 and the bogie base 8 so as to maintain the state (see FIG. 5). When there is no vehicle C on the turntable 31, the hydraulic circuit of the angle adjusting hydraulic cylinder 33 is closed, whereby the upright state of each post frame 12 is maintained.

In FIG. 6, reference numeral 34 denotes a berth for storage,
Reference numeral 35 denotes a berth for delivery. These berths are provided with roller conveyors 36 and 37, respectively. The incoming berth roller conveyor 36 is used for the incoming vehicle C
When the lift 17 rises two steps in the vehicle entrance / exit space 3 to reach 1, it is connected to the roller conveyor 7 provided on the turntable 31 of the vehicle transport device 5. Similarly, when the lift 17 rises two steps in the vehicle entrance / exit space 3 in order to send out the vehicle C2 to be exited, the exit berth roller conveyor 37 turns the turntable 3 of the vehicle transport device 5.
1 and is connected to the roller conveyor 7 provided thereon.

Reference numeral 38 denotes an opening / closing gate for partitioning between the parking device and the road.

The parking berth 34 and the parking berth 35 are not essential in this parking device. These berths 34 and 35 may be abolished and the vehicle C1 may run on the roller conveyor 7 of the turntable 31 at the same level as the ground GL by self-propelled.

The parking device constructed as described above is used as follows.

First, the operation at the time of storage will be described. The entering vehicle C1 passes through the opened gate 38 and gets into the entrance berth 34 from the roadway. After the driver gets off the vehicle and gets out of the berth 34, the gate 38 closes. At this time, the vehicle transport apparatus 5 raises the lift 17 by two steps and stands by in the vehicle entrance / exit space 3. The roller conveyor 7 on the turntable 31 of the vehicle transport device 5 is connected at the same level as the entrance berth roller conveyor 36. These roller conveyors 7 and 36 simultaneously operate in the same direction to transfer the vehicle C1 from the entrance berth 34 to the turntable 31 in the lateral direction.

When the vehicle transport device 5 receives the vehicle C1, the post frame 12 bends due to the load of the vehicle C1. Then, as shown in FIG. 5, the post-frame 12 and the bogie base body 8 are moved so that the angle adjusting hydraulic cylinder 33 automatically operates as necessary and the turntable 31 is kept horizontal. Adjust the angle between.

The vehicle transporting device 5 receiving the vehicle C1
Moves the lifting post 13 down to the lowest position along the post frame 12 by the operation of the lifting driving hydraulic cylinder 16. Here the turntable 3
1 is operated, and the direction of the vehicle C1 is reversed in advance to the exit standby state.

Thereafter, a predetermined parking section 4 serving as a parking target
The carriage body 8 runs to the side of. Second floor parking floor F2
, The bogie base body 8 travels with the lift 17 raised. On the other hand, when the vehicle is stored in the first-floor parking floor F1, the bogie base 8 travels while lowering the lift 17 along the elevating post 13.

When the truck base 8 stops beside the parking section 4 which is a parking target, the roller conveyor 6 in the parking section 4 and the roller conveyor 7 on the turntable 31 are connected to each other at the same level. The roller conveyors 6 and 7 operate in the same direction at the same time to transfer the vehicle C1 from the vehicle transport device 5 to the parking compartment 4 in the lateral direction. This completes the storage operation.

Next, the operation at the time of leaving the warehouse will be described. The vehicle transporting device 5 moves to the side of the parking section 4 in which the vehicle C2 to be left is stored. Then, the roller conveyor 6 in the parking section 4 and the roller conveyor 7 on the turntable 31 of the vehicle transport apparatus 5 work to move the vehicle transport apparatus 5 from the parking section 4.
The vehicle C2 is transferred upward.

The vehicle transporting device 5 which has received the vehicle C2
Moves to the vehicle entrance / exit space 3. When leaving from the first-floor parking floor F1, the bogie base 8 travels while raising the lift 17 along the elevating post 13. On the other hand, when the car leaves from the second-floor parking floor F2, since the lift 17 has already been lifted, the bogie base 8 travels with the lift 17 raised.

The vehicle transport device 5 raises the lifting post 13 along the post frame 12 by operating the lifting drive hydraulic cylinder 16 in the vehicle entrance / exit space 3. As a result, the lift 17 is raised, and the roller conveyor 7 on the turntable 31 is at the same level as the delivery berth roller conveyor 37, and they are connected to each other. Then, by the cooperation of these roller conveyors 7 and 37, the vehicle C2 is transferred from the vehicle transport device 5 to the berth 35 for retrieval.

Since the vehicle C2, which has been transferred into the exit berth 35, is already facing the exit direction, as soon as the opening / closing gate 38 is opened and the driver gets on the vehicle, the vehicle can be immediately exited by forward operation. Thus, the unloading operation is completed, and the opening / closing gate 38 is closed.

According to the parking device acting as described above,
Since the vehicle transport device 5 performs both the horizontal transport and the vertical transport of the vehicle C, the integration of the configuration is achieved as compared with the conventional configuration. Further, the ascending / descending post 13 which rises along each of the post frames 12 so as to protrude upward from the post frame 12 and fits within the height of the post frame 12 when in the lowest position is provided. Since the lift 17 moves up and down along the lift post 13, the lift post 13 is lowered to the lower limit position in the vehicle storage space 2, and the lift 17 moves up and down along the lift post 13. Various operations for loading and unloading can be performed only by the operation. For this reason, the height of the vehicle storage space 2 can be suppressed to a necessary minimum range in accordance with the height of the post frame 12. Since the parking device is thus made compact, it is less likely to be restricted by the area and height of the installation location.

Further, the lift 17 of the vehicle transport device 5
Data on - integrators - lever comprises a table 31, a vehicle C has receipts in advance, it is possible to goods issue in advance from a single entrance. Therefore, the convenience of use is good.

Furthermore, since the parking device according to the present invention has a simpler structure than a conventional parking device, the manufacturing cost and the construction cost are low.
