Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking apparatus for storing vehicles arranged vertically.

[0002]

2. Description of the Related Art An elevator type mechanical parking system which is relatively low in noise is known as one of the facilities for efficiently parking a vehicle on a limited site.

The elevator type mechanical parking device is
As shown in an example in FIG. 5, a hoistway 3 communicating with an entrance / exit 2 is vertically formed in a central portion of a building 1 standing on the ground, and a storage space 1 is provided at a position sandwiching the hoistway 3 left and right.
Shelf 7 which is formed with 0 and can support both ends of the pallet 5 for loading the vehicle 4 in the storage space 10 in the longitudinal direction (front-rear direction) via the transverse feed device 6, has a required arrangement pitch. A roll-up cage 9 provided in the vertical direction in a multi-tiered manner and provided with a transverse feed device 8 corresponding to the transverse feed device 6 is arranged in the hoistway 3 and installed at the top of the building 1. The chain 11 of the upper device 12 is suspended and supported, and the chain 11 is wound up and down so that the lift cage 9 can move up and down the hoistway 3.
A pit 13 for suspending the lift cage 9 is dug at the bottom of the building 1, and the lift cage 9 is suspended in advance in the pit 13, and the pallet 5 is set on the lift cage 9. When the vehicle 4 loaded from the loading / unloading port 2 is loaded in the loading / unloading port 2, the lift cage 9 is lifted to raise the pallet 5 to the position of the shelf 7 of the required stage, and then the feeding device 8 of the lift cage 9 drives the vehicle. 4 is made to traverse with the pallet 5 and can be stored in the shelf 7.

[0004]

However, with the recent increase in the number of automobiles, it is considered to increase the number of cars to be accommodated as much as possible, and it is possible to increase the height of the elevator type mechanical parking device. However, even if the number of shelves is increased by increasing the number of shelves in this mechanical parking apparatus, if there are shelves 7 on both sides, it takes a lot of time to transfer the vehicle 4 between the shelves 7 and the lift cage 9. Therefore, in order to be able to put in and take out all the vehicles in a limited time, the height is limited, and it is the actual situation that the height cannot be increased. In addition, if the drive system fails and the lift cage 9 cannot be moved up and down in the case of increasing the number of layers, it becomes impossible to store and retrieve the lift cage 9 at that time. It is an important problem that 5 can not be issued. Therefore, at present, it is not possible to simply increase the number of layers.

Therefore, the present invention focuses on the fact that a space called a void is formed in the center of a building in a recent urban high-rise house (for example, about 150 m), and by utilizing this space, a relatively low space is formed. The elevator mechanical parking system, which has the advantage of being noisy, has a high-rise structure to enhance the accommodation capacity, and also has the function of backing up even if a part of the drive system should fail. By doing so, it is intended to prevent the vehicle loading / unloading work from being hindered.

[0006]

In order to solve the above problems, the present invention provides a plurality of storages in which shelves capable of supporting a pallet for loading a vehicle are vertically arranged in multiple stages at a required pitch. The shelving groups are arranged side by side at required intervals so that hoistways are formed on one side in the left-right direction of each of the shelving groups, and the shelving of each of the shelving groups is provided in the hoistway on one side of each of the shelving groups. A lift cage is arranged so that it can be raised and lowered to and from the other side during normal delivery of pallets between
In addition, a backup function for allowing the lift cage in the hoistway at a position sandwiched by the storage shelf group among the above-mentioned lift cages to transfer the pallet to the shelf of the adjacent storage shelf group from the opposite side. It will be a configuration that has been given.

Further, a hoistway is formed outside the storage rack group at the end where transfer of the pallet to the shelf is performed only from one side, and the hoistway is connected to the rack of the storage rack group at the end. It is advisable to adopt a configuration in which a backup lift cage that allows the pallets to be delivered from the outside is arranged so that it can be moved up and down.

[0008]

The pallets are normally transferred to and from the shelves of each storage rack group with the lift cage in the hoistway formed on one side of each storage rack group. Delivery of pallets in the event of a failure is backed up by the use of a lift cage in the opposite hoistway.

Furthermore, by forming a hoistway outside the storage rack group at the end where the pallets are transferred only from one side of the lift cage, and arranging the lift cage in the hoistway, The delivery of pallets to the shelves of the storage shelving group will be backed up by a lift cage in another hoistway.
