Abstract

PURPOSE:To reduce the space lifting or lowering a pallet at a vehicle access section by providing a rotatable rotary table having a coupling section couplable from below with a coupled section provided on the pallet and a pallet mount section driven by the rotation of the rotary table on a rotating device. CONSTITUTION:When a vehicle enters a vehicle access section, the horizontal attitude of a pallet 3 is maintained by a carrying section. When the rotary table 10 of a rotating device 8 is rotated while a pallet mount section 11 is lifted by the lift system 12 of the rotating device 8, the pallet 3 mounted with the vehicle is mounted on the pallet mount section 11. The coupling section 10a of the rotary table 10 is coupled with the coupled section 3a of the pallet 3. After the pallet 3 is rotated by the rotating device 8 and the attitude of the vehicle is changed, the vehicle is lifted to the desired shelf. The drive source of the rotating device 8 can be made small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilevel parking facility,
More specifically, an elevating and lowering transfer device whose main part is an elevating table with a transfer device at the side of a vehicle accommodating rack in which a plurality of shelves for accommodating a vehicle placed on a pallet are provided in upper and lower stages. By providing the elevating path of the vehicle, the vehicle is raised and lowered while being carried by the elevating table while being placed in the above described state, and is transferred to the shelf by the transfer device to construct a three-dimensional parking structure. TECHNICAL FIELD The present invention relates to a multi-story parking facility in which a pallet on which a vehicle is placed is provided at a central portion of a pallet on which a vehicle is placed at an entrance floor portion or an exit floor portion of a structure for changing a vehicle posture while a turning device is provided.

[0002]

2. Description of the Related Art In a conventional multi-storey parking facility, as shown in FIG. 7, the entrance floor or the exit floor portion (in this conventional equipment, the vehicle entrance / exit portion 7 in which the entrance floor portion and the exit floor portion are the same). In order to maintain the horizontal posture of the pallet 3 with the vehicle A moving in or out of the pallet 3 on the upper side,
A pair of lifters 31 and 32 was arranged. The lifters 31 and 32 have a structure capable of moving the pallet 3 up and down from the height of the entry floor portion or the exit floor portion, and by the lowering operation of the lifters 31 and 32, the vehicle A The pallet 3 on which is mounted is lowered to the height of the mounting surface of the swivel carrier 8 which rotatably supports the pallet 3 in the center. Then, after it is transferred to the turning carrier 8 at that height, the posture of the vehicle A is changed by the turning operation.

[0003]

In the conventional equipment, the space for the pallet 3 in the vehicle entrance / exit portion 7 is increased and decreased by the amount of raising and lowering the pallet 3 from the height of the entry floor portion or the exit floor portion to the lower portion thereof. Had to be installed in. Then, there is a problem that an extra cost is required to secure the space. The present invention has been made in view of such an actual situation, and provides a means capable of reducing the above space while making the drive source of the turning device as small as possible, thereby reducing the cost. Has a purpose.

[0004]

A characteristic structure of a multi-level parking facility according to the present invention is to maintain a horizontal posture of a pallet on which an ingress or egress vehicle is placed on the entry floor portion or the exit floor portion in order to maintain its horizontal end. And a swivel table provided with an engaging portion capable of engaging the engaged portion provided on the pallet from below with a supporting portion for supporting a portion at a predetermined height, The pallet is mounted in a state in which the pallet is locked in the revolving direction, and the pallet mounting part is freely rotatable following the revolving of the revolving table, and the pallet mounting part is moved up and down within a set range. Is combined with an elevating mechanism for elevating from a height supported by the carrying portion to a set height above it, and relative vertical movement of the engaging portion and the engaged portion is allowed. To be And, in that the pallet mounting portion are constituted to have engagement is maintained even when raised to the upper limit of the set range.

[0005]

In the multi-storey parking facility of the present invention having the above structure,
When the vehicle enters the entry floor portion, the horizontal posture of the pallet on which the vehicle under entry is placed is maintained by the carrying unit. Then, when the turning table of the turning device is turned while the pallet placing part is raised to the upper limit of the set range by the lifting mechanism of the turning device, the pallet on which the vehicle is placed is the pallet placing part. The pallet is turned on because the engaging portion of the turning table and the engaged portion of the pallet are engaged with each other even when the pallet is placed on the pallet. Is done. Then, the vehicle is lifted up to the height of the shelves to be carried while being carried by the elevating table of the elevating and transferring device. Further, when the vehicle exits from the exit floor portion, the pallet on which the vehicle to be exited is placed from the height of the storage shelf to a position just above the exit floor portion while being carried by the elevator of the elevator transfer device. Be lowered. Then, when the pallet mounting portion of the swivel device is raised to the upper limit of the set range to mount the pallet thereon and the swivel table of the swivel device is swiveled, the swivel table is also in that state. Since the engaging portion of and the engaged portion of the pallet are engaged with each other, the pallet is turned to change the posture of the vehicle. Then, when the pallet mounting portion is lowered by the elevating mechanism of the turning device, the pallet mounted on the pallet mounting portion is mounted on the carrier portion. Then, the carrying portion maintains the horizontal posture of the pallet on which the vehicle exiting from the exit floor portion is placed.

[0006]

As described above, when a vehicle enters or exits at the entry floor or the exit floor, the pallet on which the vehicle is entering or exiting is mounted on the entrance floor or exit floor as in the conventional case. Therefore, it is no longer necessary to raise and lower it, and a vertical space for raising and lowering it is not required unlike the conventional case. As the space is saved, the extra cost for securing the space can be reduced. Further, in the above-mentioned configuration, although it is necessary to raise and lower a part of the turning device (that is, the pallet mounting portion), the turning table itself of the turning device does not move up and down. There is no need to raise or lower the drive source that turns the table. Therefore, the drive source of the lifting mechanism of the turning device can be made smaller by the amount that the drive source of the turning table is not moved up and down, and thus the drive source of the turning device can be made as small as possible.
