Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat parking lot, and more particularly to a flat parking lot capable of increasing the number of parked vehicles per unit area of land. There are a horizontal circulation type and a plane reciprocating type.

(I) In the horizontal circulation type, a car is loaded on pallets arranged on a plane, and the pallets are sequentially rotated to store the cars. The vertical type, in which the cars are parked in the traveling direction, and the horizontal type, There is a horizontal type in which the pallets move linearly at the conversion part, and a type in which the pallets move in a curved manner is called a circular circulation type.

(Ii) The plane reciprocating type transports and stores a vehicle in a plane, and there are a transport type and a retractable type. The transport type is for loading a car on a single pallet that moves in a plane, moving the pallet and dropping the car at a predetermined position and parking it.The retractable type prepares a number of pallets that can move in a plane. A car is loaded on the pallet, the car is transported together with the pallet, and a predetermined space is stored as it is.

Problems to be Solved by the Invention The conventional circular circulation type (i) requires a large area in the left and right turning parts, and when a plurality of the same parts are arranged in the horizontal direction, waste of space in the turning parts increases. However, there is a disadvantage in that the car must be cycled all the time when the car is entered. Similarly, the box-type circulation type (i) has a drawback that it is necessary to make a full circulation of the vehicle whenever the vehicle is to enter.

In addition, the conventional retractable type (ii) has a drawback that the driver needs to enter a parking room because the driving vehicle gets on the vehicle and puts the vehicle on the pallet, which is dangerous. (I
The transport type i) has a drawback in that the driving vehicle needs to move on the pallet with the entire vehicle, and an accident with the pallet may directly lead to personal injury.

The problem to be solved by the present invention is to provide a flat parking lot free from the above-mentioned drawbacks, in other words, to provide a flat parking lot that is safe and can increase the number of parked vehicles per unit area of land. .

Means for Solving the Problems The configuration of the present invention arranges a plurality of self-propelled transport vehicles in a space facing a side serving as an entrance / exit port of a parking lot, and in a parking lot other than the space where the self-propelled transport vehicles are arranged.

Driving bodies composed of motors or the like for driving the vehicle supporting surfaces may be provided on the vehicle-mounted portions of the self-propelled transfer vehicle and the self-propelled mounting vehicle. However, this method is not very economical because the number of self-propelled trolleys is much larger than the number of self-propelled trolleys.

In addition, the self-propelled transfer vehicle is provided with an in-vehicle mounting portion having a vehicle support surface and a first driver for driving the support surface, and a second drive device for driving the vehicle support surface of the in-vehicle mounting portion of the self-propelled mounting table. When the vehicle is transferred, the self-propelled transfer vehicle and the self-propelled mounting vehicle are joined together, and the driving force of the second driver of the self-propelled transfer vehicle is self-propelled via a clutch or the like. The light may be transmitted to the vehicle supporting surface of the mounting portion of the mounting vehicle. This method is very economical because it is not necessary to attach an expensive motor or other driving body to each of a large number of self-propelled mounting vehicles.

Note that the first driver and the second driver may be configured by one driver.

In the self-propelled transfer vehicle and the self-propelled mounting vehicle, the in-vehicle mounting portions may be arranged in multiple stages in the vertical direction. In this case, a plurality of in-vehicle mounting portions are vertically arranged in multiple stages on the self-propelled mounting vehicle, and the in-vehicle mounting portions are mounted on the self-propelled transfer vehicle so as to be able to move in the up and down direction. At the time of transfer, the height of the vehicle-mounted part of the self-propelled transfer vehicle is configured to match the height of the vehicle-mounted part to which the vehicle of the self-propelled vehicle is transferred. It is preferable to provide a driving body for driving the vehicle supporting surface of the vehicle-mounted portion of the self-propelled mounting vehicle in the section or the like.

When the vehicle is transferred, the vehicle supporting surface that supports the vehicle and moves in a predetermined direction may be any one that can transfer the vehicle with the self-propelled transfer vehicle and the self-propelled mounting vehicle stabilized. Although such a configuration may be used, a vehicle can be transferred in a stable state by using a vehicle support surface provided with free roller conveyors at both ends of the belt conveyor.

Instructions such as the operation of the self-propelled transfer vehicle and the self-propelled mounting vehicle for entering and exiting the vehicle can be made using a control unit provided with a computer.

The present invention provides a plurality of self-propelled transport vehicles in a parking space other than the space where the self-propelled transport vehicles and the like are arranged, leaving an empty space for forming a passage for one self-propelled transport vehicle. By arranging in a row, a part of a large number of self-propelled trolleys can be moved by self-propelling to quickly form an empty space for one self-propelled transfer trolley, and self-propelled to transfer vehicles The self-propelled transfer vehicle can be made to approach the mounting vehicle directly through the empty space. For this reason, the self-propelled transport vehicle and the vehicle supporting surface provided on the self-propelled transport vehicle are moved by a driver to transfer the vehicle from the self-propelled transport vehicle to the self-propelled transport vehicle, It is possible to quickly perform a transfer operation of transferring from the storage cart to the self-propelled transfer cart, and it is possible to reduce the time and energy required for entry and exit.

Advantageous Effects of the Invention The present invention moves a part of a large number of self-propelled trolleys in a parking lot to form an empty space through which one self-propelled transfer trolley passes and attempts to transfer the vehicles. Since the self-propelled transfer vehicle can be made to approach the mounting vehicle directly, the number of self-propelled mounting vehicles to be moved is small, and the time and energy required for entry and exit can be reduced.

The driver does not need to enter the space in the parking lot where a large number of self-propelled trolleys are located, and is safe.

When entering, transfer the car directly from the self-propelled transfer trolley to the self-propelled transfer trolley, and when entering, transfer the car directly from the self-propelled transfer trolley to the self-propelled transfer trolley. Can be operated efficiently.

It is only necessary to create an empty space that becomes one passage for one self-propelled transfer vehicle, and all other spaces will be storage space for cars (self-propelled mounting vehicles), so high-density parking is possible. is there.

If the drive of the driving body such as the motor installed on the self-propelled transfer vehicle is transmitted to the car support surface of the vehicle transfer section of the self-propelled mounting vehicle via a clutch or the like, the motor is often used for a large number of transfer mount vehicles. It is not necessary to attach a driving body such as the above, and the cost of the parking lot can be reduced.

Since the self-propelled mounting vehicle and the self-propelled transfer vehicle need only be moved in one of the x direction (opening direction) and the y direction (depth direction), the structure is simplified and the probability of failure is reduced. .

Since the moving distance of the self-propelled vehicle is only the width (the width of the self-propelled transport vehicle and the width of the self-propelled vehicle are the same) and the positional relationship of the self-propelled vehicle does not change, control by address is performed. Is easier to do.
