The winding state of the hoisting rope will be described below with reference to FIGS. 1 and 2, but the left-right direction indicates the left and right when facing the front, that is, the left and right in FIG. There are four hoisting ropes drawn around the pulleys corresponding to four moving pulleys on both sides of the pallet. The first hoisting rope W1 is provided on the front right side of the structure 1. The fixed end WE1 with the overwinding prevention mechanism is wound around the front right moving pulley A11 of the pallet 21b through the constant right pulley B11a, B11b provided on the middle trolley carriage 22b via the front right guide pulley G11. Further, after being wound around the movable pulley A12 on the front right side of the pallet 21a via the constant pulleys B12a and B12b provided on the transverse carriage 22a on the left side of the middle stage, it is provided on the opposite side of the fixed end WE1.

It is connected to the winding drum 51 via guide pulleys G14 and G15.

The second hoisting rope W2 has fixed pulleys B21a and B21b provided on the transverse carriage 22a on the left side of the middle stage from the fixed end WE2 on the opposite side of the fixed end WE1 through the guide pulley G21 on the front left side. It is wound around the moving pulley A21 on the front left side of the pallet 21a, and is wound on the moving pulley A22 on the front left side of the pallet 21b via the fixed pulleys B22a and B22b of the transverse carriage 21b on the right side of the middle stage, and then the guide pulley. Go up to the 3rd floor by G22 and G23, and wind around the moving pulley A23 on the front left side of the upper right pallet 11c via the constant pulleys B23a and B23b, and then through the constant pulleys B24a and B24b on the center of the upper tier. It is wound around a moving pulley A24 on the front right side of the pallet 11b, and further on the front left side of the pallet 11a on the upper left side via the constant pulleys B25a and B25b. It is wound around the movable pulley A25 on the side and finally connected to the winding drum 51 via the guide pulleys G24 and G25.

As shown in FIG. 2, the third hoisting rope W3 is wound around the rear moving pulley of each pallet on the same side as the first hoisting rope W1. That is, the fixed end W E3 is wound around the moving pulley A31 on the rear right side of the pallet 21b via the guide pulley G31, the constant pulleys B31a and B31b provided at the rear of the transverse carriage 22b on the right side of the middle stage, and further on the left side of the middle stage. After passing through the rear side of the traversing carriage 22a and the pallet 21a in the same manner as the first hoisting rope W1, the guide pulleys G32 and G33 move up to the third floor, and the pallet 11a on the upper left side and the pallet 11b on the upper center. The rear side of each of the above-mentioned hoisting ropes W1 is passed in the same manner as the first hoisting rope W1, and further, to the moving pulley A35 via the fixed pulleys B35a and B35b corresponding to the moving pulley A35 on the rear right side of the upper right pallet 11c. It is wound and finally connected to the winding drum 51 via a guide pulley G35.

The fourth hoisting rope (W4) (not shown) passes through the rear side of the second hoisting rope W2 in the same manner as the relationship between the first hoisting rope W1 and the third hoisting rope W3. And is connected to the winding drum 51.

Therefore, the hoisting ropes follow their respective paths from their respective fixed ends corresponding to the four front, rear, left and right moving pulleys provided on each pallet, and finally, the hoisting drum 51 of the hoisting device 5 is reached. Will be connected to.

Further, each pallet is provided with a pallet holding device 60 for holding the pallet in a raised position at four positions in the front, rear, left and right thereof, as in the moving pulley. The pallet holding device 60 is composed of a locking member 62 that is releasably engaged with an engaging portion 61 provided on the pallet, and an upper stopper 63 that regulates the rising limit of the pallet. The lock member 62 engages with the engaging portion 61 to prevent the pallet from falling.

Here, when vehicles are loaded and unloaded from the upper center pallet 11b, first, the middle trolley carts 22a and 22b and the lower pallets 31a and 31b are moved so that they move to both sides as shown in FIG. Open the central part. Then, after the lock member 62 of the palette holding device 60 of the upper stage central pallet 11b is rotated by hydraulic pressure or the like to release the engagement state with the engagement portion 61, the hoisting device 5 is operated and the winding drum 51 is operated. Rotate in the unwinding direction. When the hoisting ropes are paid out by the rotation of the winding drum 51, the pallets other than the upper central pallet 11b are held at the raised positions by the pallet holding device 60, respectively, so that the pallet holding device 60 is released. Only the central pallet 11b descends according to the amount of winding of the hoisting rope.

On the other hand, when the winding drum 51 is rotated in the hoisting direction in order to raise the lowered upper central pallet 11 b, the pallets other than the upper central pallet 11 b are respectively engaged with the engaging portions 61 of the pallet holding device 60. Contacts the upper stopper 63 and does not rise any further, so that only the upper central pallet 11b rises according to the amount of hoisting of the hoisting rope, and when it reaches a predetermined position, the lock member 62 engages with the engaging portion 61.

As described above, when lowering the upper or middle pallet, after moving the pallet below the pallet, only the pallet holding device 60 of the pallet is released to operate the hoisting device 5. Good.

By configuring the lifting device for the multi-level parking device in this way, the upper and middle pallets can be lifted and lowered by one hoisting device 5, and the number of hoisting devices can be significantly reduced. The device can be provided at low cost. Also, since the number of hoisting ropes can be reduced, the ropes can be easily managed.

Further, by disposing the hoisting device 5 in the central portion and dividing the hoisting rope into left and right, the rope tension entering the hoisting drum 51 can be made uniform, so that the fixing fitting of the hoisting drum 51 can be made small and the hoisting rope can be wound up. The device 5 can be downsized. Moreover, by providing the hoisting device 5 on the upper part of the front surface of the three-dimensional parking device, it is possible to effectively utilize the open space on the front surface.

In addition, since the pallet is hung at four places, the rope diameter and the pulley diameter can be reduced, and the pallet can be hung in a stable state. In addition, there is no need to loosen the rope because it is not significantly affected by the movement of the middle-level traverse truck.
