Then, on the lower surface side of the disc body 29, a lotion gear 30
Is formed, and the direction of the teeth is inclined with respect to the radial direction of the disc body.

In FIGS. 5 and 6, the rotary shaft 33 is arranged so as to be located on a line in the radial direction of the disc body, and is rotatably supported by the bearing device 34 on the pallet 3 side. At that time, the rotary shaft 33 becomes slidable in the radial direction of the disc body. And, a transmission gear that meshes with the lotus gear 30 at the inner end of the rotary shaft 33.
35 is fixed, and the teeth of the transmission gear 35 are also inclined in the same manner as the teeth of the lotus gear 30.

The rotary operation device 40 includes a passive chain wheel 41 fixed to the outer end of the rotary shaft 33, and a case body 42 which covers the passive chain wheel 41 and is fitted to the rotary shaft 33 so as to be relatively rotatable.

It comprises a brake receiving plate 53 fixed to the third side, an aluminum spring plate 44 for elastically urging the brake plate 52 so as to press the brake plate 52 against the brake receiving plate 53, and a fixing bolt 55.

Next, the parking operation in the above embodiment will be described. When the hand lever 46 is rotated in the reverse direction with the lock lever 47 released, the rotational force is changed to the operation shaft 43, the transmission chain wheel 44,
It is transmitted to the rotary shaft 31 via the chain 45 and the passive chain ring 41, and is transmitted to the small diameter gear 26 via the transmission gear 35, the lotion gear 30, the disc body 29, and the vertical axis 22. The rotation of the small-diameter gear 26 is transmitted to the ring gear 27 via the planetary gear 25, so that the drum portion 28
Is rotated in the feeding direction of the rope 15. Therefore, as each cord 15 is fed out, the pallet 3 is guided by the pillar 1 and descends, and lands and reaches the descending limit.

In this way, the vehicle is stopped on the support member 8 of the pallet 3 which is in the descending limit, and the hand lever 46 of the rotary operation device 40 is rotated in the reverse direction, that is, in the normal rotation. Then, the rotation of each part is performed in the opposite manner to the above, and thus the drum part 28 is rotated in the winding direction of the cord 15.

As a result, the length of the rope 15 above the guide portion 10 is gradually shortened, so that the pallet 3 is guided by each of the columns 1 and ascends. In this way, with the pallet 3 raised to the upper limit, the lock lever 47
Is rocked to the engaging position, and the hand lever 46 is engaged with the lock lever 47. Then, by stopping the car below the pallet 3, the two cars can be positioned vertically and parked.

As described above, when the pallet 3 supporting the vehicle reaches the upper limit and the manual rotation of the hand lever 46 is stopped, the pallet 3 side tries to lower due to the load. Then, the descending force acts on the cord 15 from the guide portion 10 and tries to rotate the drum 20 in the opposite direction to the above, that is, to the descending side.

Then, the descending side rotational force of the drum 20 finally becomes the rotational force of the lotus gear 30 via the disc body 29, and tries to rotate the rotary shaft 33 via the transmission gear 35. At this time, since the tooth directions of both gears 30 and 35 are inclined with respect to the radial direction, an outward thrust force A acts on the rotating shaft 33. This sliding force causes the brake plate 52 to move to the brake receiving plate 53.
The brake device 50 automatically applies a braking action to prevent the pallet 3 from descending.

The operating rotational force for lowering the pallet 3 overcomes the thrust force A described above, so that the braking can be automatically released to perform the lowering.

[0023]

According to the present invention having the above-mentioned structure, the car is stopped on the pallet at the lower limit, and the drum is rotated through the rotary shaft by the manual rotation of the rotary operation device to wind each cord. By doing so, the length of the upper rope can be gradually shortened from the guide portion, and the pallet can be guided and raised by each of the columns. In this way, by raising the pallet to the upper limit and then stopping the car below the pallet, the two cars can be parked vertically.

As described above, when the pallet supporting the vehicle reaches the upper limit and the manual rotation is stopped, the pallet side tries to descend due to the load, and the descending force acts on the rope body from the guide portion to move the drum. It tries to rotate in the opposite direction, that is, to the descending side. Then, the braking force is automatically applied to the brake device by the rotating force of the drum on the descending side, whereby the descending of the pallet can be prevented.

As described above, according to the present invention, by using a manually operated rotary operation device and employing a brake device that operates automatically, it is possible to provide a simple structure and assembly at low cost, and a simple structure. Therefore, abnormal (fault)
Is easy to understand and can prevent accidents.
