Next, the operation of the boat parking apparatus 10 having the above structure will be described. The boat A, which has been landed from the water by a crane or the like, is placed on the support portion 56 of the carriage 33,
It is moved to the lifter 31 of the boat parking device 10 by an appropriate transfer means.

This boat A is connected to the boat parking device 10 by, for example, the upper floor 1
5, when the boat A is to be accommodated in
After being lifted up to the upper floor 15, the cart 33 is placed on the corner portion where the vertical rail unit 21 and the horizontal rail unit 23 intersect by pushing the cart 33 through the loading / unloading opening 30 by the pushing mechanism.

Then, the carriage 33 is moved vertically or horizontally along the vertical rail unit 21 or the horizontal rail unit 23 toward the desired storage position. The vertical movement is performed by rotating the motor 98 of the vertical drive mechanism 91, and the horizontal movement is performed by rotating the motor 113 of the horizontal drive mechanism 92.

When the carriage 33 moves from the vertical rail unit 21 to the horizontal rail unit 24, or from the horizontal rail unit 23 to the vertical rail unit 22, the traveling direction of the carriage 33 changes by 90 °. At this time, only the traveling direction changes to a right angle without changing the direction of the carriage 33.

That is, the carriage 33 is the turntable 1
When the vehicle moves to the corner where 25 is provided, the carriage 33 stops temporarily, and the four casters 57
However, it stops at a predetermined position on the turntable 125 as shown in FIGS. In this state, when the driving mechanism 91 (or 92) applies a force in the direction for switching the traveling direction of the carriage 33 to the carriage 33 to the carriage 33,
The wheel 60 and bracket 121 of the No. 7 turn 90 ° with the turntable 125 about the vertical axis C1.

In this case, since the turntable 125 rotates about the vertical axis C2, the above turning motion of the casters 57 is made smooth, so that the four casters 57 all change their direction in the moving direction of the carriage 33. .. Therefore, the switching of the traveling direction is smooth, and the casters 5
7 and the drive mechanisms 91 and 92 are not unduly applied.

When the boat A accommodated in the boat parking apparatus 10 is to be unloaded, the boat A is placed in the loading / unloading port 30 contrary to the above.
Move towards. For example, if you want to leave the lower right boat A1 in FIG.
By moving in three directions, the second
An empty space is formed at the right end of the horizontal rail unit 24 in the figure.

Next, by moving the boat A2 located at the right end of the first lateral rail unit 23 in the direction of arrow F4 in FIG. 7, the desired boat A1 as shown in FIG.
Is put in a state in which it can be put out from the loading / unloading opening 30. The series of loading and unloading operations described above are automatically performed by commands issued by a control device (not shown) using a microcomputer or the like.

[0046]

According to the present invention, it is possible to continuously feed a dolly horizontally using a chain, and it is also possible to feed a plurality of dollies at the same time, if necessary. Since the chain may be arranged along the rail in the moving direction of the truck, the truck can be efficiently sent with a relatively simple structure that does not take up space, and the truck loading / unloading operation is easy.
