Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a parking lot system that allows cars to be parked in a multi-dimensional manner in a vacant lot or the like without requiring any building structure. (Conventional Technique IN) Conventionally, in order to make effective use of land, many parking lot systems have been adopted in which cars are parked vertically in a multi-dimensional manner. A typical example is a circulating multi-story parking lot in which an endless conveyor with trays on which cars are placed circulates up and down within a tower-like building. Since the circulating multi-level parking lot simply circulates trays in the vertical direction,
It is not possible to park cars in multiple rows, the storage efficiency per unit of equipment is poor, and the cost of buildings and other equipment increases, resulting in high costs.

On the other hand, multiple rows of one or more rows of box-shaped cases that can store cars are arranged vertically, and a crane is used to move the desired row up and down until the case containing the desired car reaches the floor. Parking systems that move the vehicle have also been proposed (for example, Japanese Utility Model Application Publication No. 59-22863, Japanese Unexamined Utility Model Publication No. 49-27036, Japanese Utility Model Application No. 51-16).
Publication No. 0376, etc.).

(Problems to be Solved by the Invention) However, all of the above proposals require above-ground or underground structures for storing storage cases in multiple stages.
Moreover, in order to lift all the cases in the same row all at once, a large lifting device is required, which requires a large amount of equipment cost and is relatively expensive, and the drawbacks of the above-mentioned circulating type multi-level parking garages have not yet been solved. In addition, handling was troublesome as the cases had to be connected and separated, and there was also the drawback that it took time to store and unload. The present invention was devised in view of the above-mentioned drawbacks of conventional parking lots, and allows car storage cases to be moved independently and stacked in any vacant space, without requiring a building and requiring no equipment costs. The purpose is to provide a parking system that is inexpensive and can accommodate a high number of parking spaces per unit area. (Means for solving the problem) The parking system of the present invention that achieves the above object
A plurality of car storage cases of a size that can store a car, a running rail laid in a parking lot space, a car running on the running rail, lifting the car storage case, and moving the car storage case in a vertical direction along the rail. and a traveling crane that can be moved to a desired position in the lateral direction.The vehicle is stored in the case at the warehousing position, and the case is lifted and moved by the traveling crane onto an empty space. Store by stacking them in multiple tiers. When leaving the garage, the cases containing the desired cars are lifted up again from the stacking position by the traveling crane and moved to the leaving position. (Function) The maximum parking capacity according to this method is Note: If the capacity of the first tier is N, and if the car is stacked in n tiers, and the car stored in the car storage case located at the bottom is to be taken out, there is a space to move the case located at the top. must be left empty, so the number of storage units on the top shelf is N-(n-
1), and the overall result is nXN-(n-1).
For example, when parking in two tiers, there is one empty space in the upper tier. Therefore, even if the case containing the car to be taken out is on the lower level, the case can be lifted up by the crane and transported to the delivery position. Once the case is empty after being unloaded, it is lifted up again and moved to the storage position, where it waits for the next car to arrive. ? An empty case is always waiting at the warehousing position unless it is a p4 cup, and the incoming car enters the case, and the crane moves according to the command from the main controller to place the case in the empty space. put. All warehouse entry and exit management in this system can be automated using computers. As described above, according to this system, cars are stored in cases and parked in multiple tiers in multiple widths and widths, so there is no need for a special building, and as long as there is an open space, cars can be parked in the open space. It can be easily implemented by simply installing a traveling crane, and the equipment cost is low and storage efficiency is high. The span of the crane and the length of the traveling rail can be set appropriately according to the size and shape of the plaza, and there are fewer restrictions on the topography of the installation location. There is no need for the driver to enter the parking space, and the vehicle is automatically transported unmanned, making it safe and easy to manage entry and exit. (Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

The drawings show an embodiment of the multi-level parking system of the invention. In the figure, 1 is a traveling gantry crane that runs on a rail 2 laid with an appropriate span in a vacant lot, etc., and its height is as follows: It has an appropriate height that allows it to be lifted and transported. A horizontal running rail 3 is provided at the top along the span direction, and a cart 4 having a lifting device 5 for hoisting a car storage case (described later) is automatically moved along the rail by electric power. ．． The lifting device 5 is composed of a suitable lifting device such as a hydraulic cylinder device installed on a rotary disk, and has an engaging device l! that engages with the car storage case. 6, which can automatically engage and lift the car storage case. The engaging device 6 may be, for example, as shown in the figure, a pair of opening/closing clamps that are electrically opened and closed to engage with a locking edge of the case, or an electromagnetic system, or any other appropriate device.

The car storage case 10 has sufficient rigidity to store and stack cars, and is constructed like a box or cage with openings at the front and back, so that the cars stored inside will not move unexpectedly. Appropriate safety devices such as wheel chocks are installed to prevent this from happening. In addition, appropriate identification marks and the like are provided at appropriate locations on the case for managing entry and exit.

Next, a method of entering and exiting the garage using the above-mentioned apparatus will be described, for example, in the case where the vehicles are parked in a vacant lot in four rows and three rows, stacked in two tiers, as shown in the figure. In that case, the site size basically includes a parking space with a flat area of AX12 for a car storage case, a space for running a gantry crane with rails on both sides, and an entrance space for entering and exiting the warehouse. It's good to have. The maximum parking capacity of the parking lot is 23 cars in this embodiment.

Therefore, with 23 cars currently parked, there is space for one case in the upper row. When leaving the garage from this state, for example, the location of the case in which the car is stored is stored in the storage card, and by inputting this card into the controller, the case in which the car is stored is moved to the upper stage. In some cases, the gantry crane travels on the rails, and the cart moves along the transverse rails until it reaches the upper part where a given case is located, and the lifting device is activated to lower the engagement device. Then, the crane engages with the engaging edge of the car storage case to lift the case, the crane returns to the unloading position, and above the crane, the rotary disk supporting the lifting device on the truck rotates 180 degrees, After reversing the direction of the car, the car is lowered to the exit position 12.

Therefore, the car can move forward directly from the case and leave the garage. can.

On the other hand, if the case containing the car to be taken out is on the lower level and another case is placed on top of it, you will need to move the case above it to another location and open the top part. ．． Therefore, in the present invention, at least one case is always placed on the upper stage so that the case placed on the upper part can be moved to another place.
There are several empty spaces available. The location of the empty space is always input to the main controller, and the case located above the predetermined case to be delivered is lifted by a lifting device and moved to the empty space by a crane according to instructions from the main controller. Moving. If there are multiple empty spaces, the main controller selects the closest empty space and moves the case there. After the upper case is moved in this way, a predetermined case is lifted up and moved to the exit position using a method similar to that described above, and the car is exited from the garage. Once the case is empty after being unloaded, it is lifted up again and moved to the storage position, where it waits for the next car to arrive. Also, if an empty case is already waiting at the standby position,
Move the case to the parking space section again and place it in an empty space.

In addition, when entering the parking lot, as mentioned above, unless the parking space is full, there is always an empty case waiting at the parking location, so a car with a passenger can enter the case directly. However, tires and the like are fixed by appropriate means so that they do not move within the case. Then, after the driver evacuates from the case, when he presses the activation button on the controller, the lifting device is activated to lift the case, and the crane moves based on commands from the main controller to store the case in an empty space. ,Then, the crane returns to its home position, the warehousing position, and waits.

In the illustrated example, the crane travels on a straight track, and the loading and unloading positions are located on the same side, but the loading and unloading positions may be located on opposite sides, or if the parking space is In the case of an irregular shape such as a circle, the design can be changed as appropriate, such as arranging the rails in a curved line, to match the shape.

(Effects) The present invention has the above-described configuration and provides the following special effects.

Since cars are stored in cases and parked in the open in multiple tiers across multiple widths, there is no need for a special building, and if there is an open space, it can be easily implemented by simply installing a traveling crane in the open space. The equipment cost is low and the storage efficiency is high. The span of the crane and the length of the running rail can be set appropriately according to the size and shape of the plaza.
There are fewer restrictions on the topography of the installation location. There is no need for a driver or the like to enter the parking space, and the vehicle is automatically transported unmanned, making it safe and easy to manage entry and exit.
