At the base end of the mounting body 1, a car stop 11 is projected. Further, a rear wheel holding device 7 for fixing a rear wheel of the container chassis s is provided near the base end of the mounting body 1, and a chassis main body of the container chassis s is provided near the tip end of the mounting body 1. There is provided a chassis holding device 8 for fixing the. The structures of the rear wheel holding device 7 and the chassis holding device 8 will be described in detail later.

Next, the fixing device 6 will be described with reference to FIG. This fixing device 6 fixes the container chassis s whose front end is raised in that state.
A pair of left and right upper frames 61 and front end fixing bodies 62 provided at equal intervals on the upper frame 61 are provided. The upper frame 61 is supported by many columns 63. Further, as shown in FIGS. 4 and 5, the front end fixing body 62 is rotatably provided on the upper frame 61, and is provided between an open state parallel to the upper frame 61 and a closed state orthogonal thereto. It rotates and allows the container chassis s to enter in the open state, and fixes the container chassis s in the closed state. In this embodiment, as shown in FIG. 1, front end fixing bodies 62 are provided on the left and right sides of the upper frame 61 so that the container chassis s can be parked on both sides of the upper frame 61. Of course, it is also possible to park the container chassis s only on one of the left and right sides.

Here, a parking method using the parking device for the container chassis will be described. First, a description will be given from the state where the parking device for this container chassis has no parking container chassis at all. In this state, the carriage 31 of the moving device 3
Is located at the front end of the moving device track 4, and the rotating arm 51 of the rising device 5 is in a substantially horizontal state as shown in FIG. It is almost horizontal.

From this state, the towing vehicle that has pulled the container chassis s is retracted, and as shown in FIG. 6, the rear wheels of the container chassis s are on the platform 1, and
The vehicle stops when it is in contact with the car stop 11. At this time, the rear wheel holding device 7 and the chassis holding device 8 are in a non-operating state, and the rear wheels and the chassis of the container chassis s are not fixed to the platform 1.

Next, the container chassis s and the towing vehicle t are separated, the towing vehicle t advances, and the container chassis s

The wheel 32 is rotated by the operation of the drive device, and the carriage 31 is moved backward while being guided by the moving device track 4. Moving.

By moving to the rear, the substantially upright container chassis s retracts in parallel with the upper frame 61 of the fixing device 6. At this time, all the front end fixed bodies 62 are in an open state, and the container chassis s extends to the rear end of the upper frame 61.

Next, as shown in FIG. 10, the mounting body 1 is
By the operation of the hydraulic cylinder, it moves downward along the rotating arm 51, and the rear end of the container chassis s is grounded. At this time, by mounting the rear end protection member 9 in advance, it is possible to prevent the rear end of the container chassis s from being damaged. Furthermore, if an appropriate protective member (not shown) is provided at this grounding position and the rear end of the container chassis s is grounded on this protective member, the rear end protective member 9 need not be attached one by one. The rear end can be protected, and the positional shift of the rear end of the container chassis s can be more reliably prevented.

After the grounding is completed, only the rearmost front end fixing body 62 is in the closed state, and abuts against the lower surface on the front end side of the substantially upright container chassis s to fix it. Then, the rear wheel holding device 7 is released and the rear wheel of the container chassis s is opened. Finally, the chassis holding device 8 is released and the chassis of the container chassis s is opened. As a result, the container chassis s is supported by the rearmost front end fixed body 62 of the upper frame 61, and parking is completed.

Next, as shown in FIG. 12, the platform 31 is moved forward while the platform 1 is further lowered by the operation of the hydraulic cylinder (arrow a) and guided by the moving device track 4. (Arrow b). Then, when the platform 1 moves to a position where it does not interfere with the container chassis s, the platform 1 is raised to the uppermost position in the initial state by the operation of the hydraulic cylinder (arrow c), and the carriage 31 continues to move further forward. (Arrow d).

After the carriage 31 moves forward, the start-up device 5 returns to the initial state. That is, the rod of the ascending / descending hydraulic cylinder 53 contracts so that the rotating arm 51 becomes substantially horizontal. Then, the next container chassis s is carried in by the tow vehicle, the above-described operation is repeated, and the container chassis s is fixed to the front end fixed body 62 which is the second from the rear. After that, in the same manner, a plurality, 10 in FIG.
Parking of the container chassis s is completed. In FIG. 1, a total of 20 container chassis s can be parked, 10 on each side of the upper frame 61.

On the other hand, when carrying out the container chassis s while parked, the reverse procedure to the above may be followed. For more information,
The carriage 31 is retracted so that the rotary arm 51 and the mounting body 1 which are in a substantially upright state are along the frontmost container chassis s. The mounting body 1 is lifted a little, and the rear wheel of the container chassis s is brought into contact with the car stop 11 of the mounting body. The rear wheel holding device 7 and the chassis holding device 8 are operated to hold the container chassis s and open the front end fixing body 62. After the platform 1 is lifted, the rear end of the container chassis s is floated in the air, and the carriage 31 is advanced to the foremost position.
Is rotated to a horizontal state to ground the container chassis s in a horizontal state, and the rear wheel holding device 7 and the chassis holding device 8 are
To cancel. As a result, the container chassis s is brought into a free state, connected to the towing vehicle, and carried out.

Now, referring to FIG. 13, a preferred embodiment of the rear wheel holding device 7 will be described. This device is arranged on both sides of the mounting body 1, and the force points 71,
It has an action point 72 and a fulcrum 73. The right and left power points 71 are

It is something that is done. Incidentally, FIG. 13A shows a holding state and FIG. 13B shows an open state.

Next, referring to FIG. 14, a preferred embodiment of the chassis holding device 8 will be described. This device has first, second and third arms 81, 82, 8 respectively.
3, the first arm 81 is rotatably connected to a mounting body (not shown in FIG. 14). In addition, each arm 81,
The parts 82 and 83 are rotatably connected and can be rotated by a hydraulic cylinder or the like. Then, from the folded state shown in FIG.
After the state shown in (C), the holding projection 84 is projected on the second arm 82 by moving to the holding state shown in (D).
And the third arm, the chassis of the container chassis s is held.

Next, with reference to FIG. 15, a desirable example of the structure for opening and closing the front end fixing body 62 will be described. This front end fixing body 62 is, as shown in FIG.
The arm 621 and the second arm 622 are rotatably connected, and the first arm 621 is rotatably supported by the upper frame. Although the upper frame is not shown in FIG. 15, the first arm 621 and the second arm 622 are parallel to the upper frame in FIGS. 15A and 15B. In (D) of 15, the first arm 621 and the upper frame form a right angle. The first arm 621 is rotated by the electric motor 623 and the gear 624, and is
The arm 622 rotates with respect to the first arm by a connecting rod 625 that interlocks with a gear 624. Thereby, from the open state of FIG. 15B to the state of FIG.
(D) is in the closed state.

As will be understood from the above description of the operating state, the front end fixing body 62 is closed from the rear side when the container chassis s is carried in, and conversely when the container chassis s is carried out. The fixed body 62 is opened from the front side. Therefore, the structure for opening and closing the front end fixed body 62 is sufficient if it can satisfy such movement. Therefore, it is possible to use a cam or the like to sequentially open and close all the front end fixed bodies 62 with a single rotary drive source. Further, each front end fixed body 62 is provided with a hydraulic cylinder, and its opening and closing is performed by its operation.
The structure for opening and closing can be changed as appropriate.

After that, it is preferable to further start up the container chassis s and perform the above-described work of mounting on the vehicle stand 200. This is to prevent the rear end of the container chassis s from colliding with the vehicle stand when moving backward. Therefore, if the construction cost is not taken into consideration, the hollow portion may be dug deeper to lower the position of the vehicle stand. By doing so, the container chassis s may be retracted in an almost upright state from the beginning. You can Further, even if the vehicle stand is configured to be able to move up and down by the hydraulic cylinder, the container chassis s can be retracted in an almost upright state from the beginning.

Next, still another embodiment will be described with reference to FIG. In the previous embodiment, the mounting body was mounted on the trolley 31 of the moving device 3 in a state in which the mounting body was provided on the rotating arm 51 of the rising device 5, but in this embodiment, a plurality of moving mounting bodies 300 are mounted.

The parking method using this parking device will be described. The container chassis s stops with the rear wheels placed on the moving platform 300. Next, the raising device is actuated, the turning arm 51 is turned, and the front end side of the container chassis s is raised and raised. At this time, the chassis of the container chassis s rotates about the axle of the rear wheel on the moving mount 300. Next, when the carriage 31 moves backward, the moving mount 300 connected to the carriage 31 also moves backward, and the container chassis s is moved to a predetermined position. Thereafter, the front end side of the container chassis s is supported by the fixing device 6 as in the previous embodiment, the parking is completed, and the connection between the carriage 31 and the moving mount 300 is released.
Only the dolly 31 moves forward. Therefore, during parking, the container chassis s remains in a state where the rear wheels are placed on the moving platform 300.

In each of the above embodiments, the rotating arm 51 is rotated to raise the front end side of the container chassis s to raise the container chassis s. At this time, It is the rotating arm 51 or the transfer plate 52 between the rotating arms that is in contact with the front end side of the container chassis s. In the first and second embodiments, You may make it extend the mounting body 1 so that the front end side of the mounting body 1 may contact | abut to the front end side of the container chassis s.
