Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a parking lot with a two-tiered parking system, and is applicable to vehicle production line transportation, stock equipment, loading/unloading equipment for vehicles on ferries, etc. can also be applied.

[Conventional technology]

As a parking device that makes use of land in a multi-dimensional manner, there is a multi-story parking facility as shown in Fig. 5. In FIG. 5, 1 is a drive device, la is a cage, and 2 is a vehicle. The vehicle 2 enters and exits from the garage at the lowest position of the cage 1a that circulates in a vertical plane, and is stored by the upper cage 1a.

In addition, when parking on a flat surface such as a vacant lot, the driver has to arbitrarily choose a place to park, which requires a parking area that is nearly twice as large as the area occupied by a car.

[Problem to be solved by the invention]

(1) In the multi-level parking general facilities shown in Figure 5, □
In order to take one vehicle 2 out of the warehouse, all the vehicles 2 must be moved by the drive device 1, which causes problems such as energy loss and noise generation.

(2) In the case of conventional parking equipment that moves on a flat surface, a space is created below the parked vehicle to place the equipment, which requires ground excavation and drainage, resulting in large installation costs, and the need for a pallet to carry the vehicle. There are problems such as the structure is complicated and expensive! (3) Furthermore, with the conventional devices mentioned in (1) and (2) above, it is not easy to change the layout, especially to reduce the number of parking spaces, and it takes a lot of effort to restore the parking lot site to its original open space. There are problems such as the construction time and cost required.

An object of the present invention is to provide a planar parking type parking facility that is simple in structure and inexpensive in equipment.

[Means to solve the problem]

(1) The pallets on which the vehicles are placed are moved one by one independently, and the intermediate space between the upper and lower tiers is used as the transport space. Vehicles on pallets are loaded and unloaded using a self-propelled elevator.

(2) No mechanical mechanism is provided to the pallet, and equipment under the parking lot floor is not required. Running, going up and down.

All pallet lifting mechanisms will be incorporated into a self-propelled elevator.

(3) The upper pallet holding mechanism is a twist lock that attaches a one-touch type pallet holding device to the frame extended above the traveling rail gutter and holds the hook by rotating it 90' with the upward stroke of the self-propelled elevator.

(4) Item (1) above allows access to any palette.

[Function] (1) Energy saving and quiet operation are achieved by taking out each pallet individually without moving the entire pallet.

(2) Installation is easy because there is no mechanism on the bottom of the pallet.

(3) The lifting mechanism of the self-propelled elevator can raise and lower pallets to both the lower and upper tiers with a single lifting mechanism.

(4) Since the upper pallet holding mechanism is one-touch operation, it has a simple structure similar to that of the lower pallet.

In FIG. 1(b), a self-propelled elevator 3 travels on a traveling rail 4, and lifts and transports a pallet 5 together with a vehicle 6 placed on the pallet. When warehousing, after setting pallet 5 to the warehousing/unloading position (on the turntable),
The vehicle 6 enters and stops on the pallet 5, and the vehicle 6 placed on the pallet 5 is moved to the loading/unloading position and exits.

Next, the warehousing operation will be explained with reference to FIGS. 1(a) and 1(b).

A vehicle 6 enters and stops on the pallet 3 set on the loading/unloading position (on the turntable) 9.

When the vehicle driver gets off the vehicle, the turntable rotates 90 degrees and stops at the holding position of the self-propelled elevator. The lifting device lowers and holds the pallet 5, and the pallet 5 and the vehicle 6
is lifted up, moved through the intermediate space between the upper and lower parked vehicles, transported to a predetermined parking position, and unloaded the vehicle 6 together with the pallet 5. The lower pallet is only placed on the pallet support stand, but the upper pallet is held by the pallet holding devices 25 provided on the upper gutter 20a fitting into holes at the four ends of the pallet.

In preparation for the next warehousing vehicle, the self-propelled elevator 3 takes out an empty pallet 5 from either the upper or lower tier, sets it above the warehousing/unloading position 9, and waits. The above operations are repeated to continuously store vehicles.

Next, an example of the unloading operation will be explained with reference to FIGS. 1(a) and 1(b).

In response to the unloading command, the self-propelled elevator 3 travels to a predetermined parking position and lifts the relevant pallet 5 together with the vehicle 6 or, if it is on the upper stage, a pallet holding bag! 25, moves through the intermediate space between the upper and lower parked vehicles, stops at the loading/unloading position (above the turntable), and unloads the pallet 5 and loaded vehicle 6.

Next, the turntable rotates 90 degrees, the car faces the exit direction, the vehicle driver gets on the vehicle, and the vehicle 6 exits.

Next, the pallet 5 from which the vehicle 6 has left is rotated 90''' on the turntable, held again by the lifting device 16, and returned to its original position, completing the series of operations.

In this embodiment, a case is shown in which there is one home position for both warehousing and warehousing, but even when the warehousing position and the warehousing position are at each location, the warehousing and unloading can be performed with approximately the same movement of the rod.
