Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a tunnel parking system that utilizes a laterally extending tunnel provided underground as a parking space.

(Prior Art) A parking device that utilizes the basement of a building as a parking space is generally known. For example, JP-A-60-7
Publication No. 3972 discloses that an upper and a lower parking area is formed in the basement of a building in which pallets for carrying vehicles can be horizontally transferred, and the pallets are circulated between the two parking areas. , a vehicle is described in which a lifting means is provided at the end of the lateral transfer path for lifting and lowering a vehicle on a pallet between the entrance and exit on the ground and both parking sections.

In addition, vehicles can be parked on a dolly as a parking device built on the ground.
It is known that parking sections are provided on both sides of the transport lane for vehicles to be transported on a dolly, and vehicles are transferred between the above-mentioned dolly and the parking section (for example, Utility Model No. 59-185).
(See Publication No. 366).

That is, in this device, the dolly is provided with a movable platform equipped with a comb-shaped fork for supporting the tires of the vehicle, while a comb-shaped receiver for vertically passing the fork through each parking section is provided. The movable platform on the dolly is moved above the parking section, and the movable platform and the parking section are moved up and down relative to each other. Vehicles are transferred at the station.

(Problem to be solved by the invention) In recent years, it has become difficult to obtain land for parking lot construction, making it impossible to construct large-scale public parking lots, and roads in urban centers have become paralyzed due to illegal parking. .

Therefore, focusing on the effective use of underground space under roads and rivers, research is being conducted on forming tunnels and using the interior space for parking lots, much like the construction of subway lines.

However, when constructing an underground tunnel-type parking lot, the construction cost is several times higher than when constructing it above ground, so in order to quickly recover this construction cost, the number of parking spaces per unit space should be reduced. It is desirable to improve the efficiency of parking in a limited space by increasing the number of parking spaces and allowing vehicles to enter and exit quickly.

The present invention has been made in view of the above, and an object of the present invention is to divide the space inside the tunnel in the vertical direction to form a plurality of parking floors, and to park vehicles in each of the parking floors in the tunnel. By taking appropriate measures to park in multiple rows in a longitudinal direction, the number of parking spaces per unit space can be increased, and vehicles can be entered and exited quickly.
The aim is to improve the efficiency of parking in limited spaces.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention includes a tunnel provided underground extending in the horizontal direction, and a tunnel provided in layers in the vertical direction within the tunnel. The target is a tunnel parking system in which vehicles are parked on multiple parking floors.In this case, a large number of dollies that transport vehicles in the longitudinal direction of the tunnel are installed in each parking floor in an empty space for an appropriate number of vehicles. A plurality of rows are provided in a tandem arrangement in the longitudinal direction of the tunnel so as to form a plurality of tunnels. Furthermore, a traverser for transporting the vehicle in the tunnel width direction while crossing between the columns of each dome 9,
Provided at predetermined pitches on each of the above parking floors. Further, a lifting means is provided for vertically transporting the vehicle between each of the parking floors and the vehicle loading/unloading section.

(Function) With the above configuration, in the present invention, when a vehicle enters or exits between the vehicle entry/exit section and each parking floor column directly below the vehicle entry/exit thick section, the dolly moves directly under the vehicle entry/exit thick section. , the vehicle is transferred between the dolly and the elevating means. Also,
When a vehicle enters or exits between a vehicle entry/exit section and a column of each parking floor located laterally (in the tunnel width direction) from the vehicle entry/exit section, the vehicle located at the vehicle entry/exit section is moved by an elevating means. After passing the uke to the traverser waiting directly below,
Due to the traversal movement of the traverser, the receiver is laterally removed from the vehicle entry/exit section and is passed to a waiting dolly and stored therein, while the vehicle is entered in the column of each parking floor that is laterally removed from the vehicle entry/exit section. After the dolly is moved to the side of the vehicle entrance/exit section, the platform is passed to the traverser waiting at that position, and then the traverser moves sideways to the elevating means waiting just below the vehicle entrance/exit thick section. The receipt is handed over and the goods are taken out.

In this way, vehicles are arranged in tandem in the longitudinal direction of the tunnel at each of the plurality of parking floors, which are formed by dividing the space inside the tunnel in the vertical direction. Because parking is arranged in multiple rows, the number of parking spaces per unit space increases.

Moreover, since a large number of Dor9-s are arranged in tandem in the longitudinal direction of the tunnel to create an appropriate number of empty spaces, parking on the floor above is possible immediately after the vehicle is delivered downstairs. If the elevating space on the floor is left empty, the elevating operation of the elevating means will not be hindered, and therefore, while vehicles are being delivered on the upper and lower parking floors, vehicles can be entered by running a dolly on the upper parking floor. This allows the vehicles on the floor to enter and leave the warehouse quickly without getting stuck.

Therefore, the efficiency of parking in a limited space can be improved.
