It is characterized in that it is provided with a rotating piece for holding the engagement between the engaging member received in the concave portion of the holding member and the lock piece when in the stop position.

<Operation> When the carrier-side lower connecting member is in the lowered position in the column device and the carrier-side upper connecting member descends and abuts against the carrier-side lower connecting member, the lower surface of the carrier-side upper connecting member includes the rotating piece. The lock piece is pressed and rotated downward to open the recess in the lock piece. Therefore, the engaging member of the container-side lower connecting member can be easily fitted into or separated from the recess of the holding member of the carrier-side lower connecting member.
On the other hand, when the carrier-side lower connecting member is in the lowered position in the column device and the carrier-side upper connecting member rises and separates from the carrier-side lower connecting member, the lower surface of the carrier-side upper connecting member separates from the rotating piece. Then, the rotating piece is locked at the locking position so that the lock piece holds the engagement of the recess. Therefore, when the carrier-side upper and lower connecting members come into contact with each other, the engaging member of the container-side lower connecting member fitted into the holding member of the carrier-side lower connecting member is disengaged from the holding member. There is no. That is, by vertically moving the carrier-side upper connecting member, the carrier-side lower connecting member and the container-side lower connecting member are automatically connected or released. Therefore, there is no risk that the container will be dropped and damaged during lifting.

Therefore, it can be driven up and down according to the movement of the piston rod 71a. Also,
In this case, the carrier-side upper connecting member 61 and the carrier-side lower connecting member 91 are both at the lowest point (hereinafter, referred to as “down position”) in the column 55 as shown in FIG. 5 (a). Only close up and down when there is, and on the contrary, the fifth
As shown in FIG. 2B or FIG. 2C, when at least one of them is in a position other than the lowered position, the tube 71b and the piston rod 71a are regulated by the length and separated from each other. Therefore, when the carrier-side upper connecting member 61 and the carrier-side lower connecting member 91 are in the lowered position in the column device 51, the operating pin 69 and the connecting rod 92,
The operation of the lower part 63b of the clevis 63 and the pressing plate 109 releases the connection between the clevis 63 and the clevis 95. On the other hand, when the carrier-side upper connecting member 61 or the carrier-side lower connecting member 91 is in a position other than the lowered position, the clevis 63 and the clevis 95 are connected by the connecting pin 95 and the lock piece 105, respectively.

The container handling vehicle configured as described above operates as follows.

Now, the carrier 45 and the container 1 are in the same state as shown in FIG. 6 (a), the container-side lower connecting member 16 is in the raised position, and the supporting member 3 is in a state of being retracted in the rear column 5. . Further, the carrier-side upper connecting member 61 and the carrier-side lower connecting member 91 are in the lowered position in the column device 51 as shown in FIG.
Clevis 63 and 95 are assumed to be in a disconnected state. In this state, the container-side upper connecting member 11 is fitted into the recess 63c of the clevis 63 of the carrier-side upper connecting member 61. Since the clevis 63 has the connecting pin 65 removed, it can be easily fitted or separated. Further, the engaging member 17 of the container-side lower connecting member 16 is fitted into the recess 95c of the clevis 95 of the carrier-side lower connecting member 91. The lock piece 105 of the carrier-side lower connecting member 91 is in a state where it does not come into contact with the rotating piece 103 and is simply hung by the weight of the shaft 8 under its own weight. It is possible to easily fit the recess 95c of the clevis 95 by repelling the lock piece 5 at the position shown in FIG. Note that the lock pieces 5 can be flipped in the opposite direction to easily separate them. Next, when the hydraulic cylinder 71 is extended as shown in FIG. 5 (b), the tip of the piston rod 71a is supported by the pedestal 48,
Ascends to the tube 71b, and the upper sprocket 82 rises. Since the upper chain 84 is fixed to the bridge 53 on one end, the carrier-side upper connecting member 61 attached to the other end of the upper chain 84 rises as the upper sprocket 82 rises. on the other hand,
The carrier-side lower connecting member 91 remains stationary in the lowered position of the column 55. Then, by separating the carrier-side upper connecting member 61 and the carrier-side lower connecting member 91,
The operating pin 69 is separated from the connecting rod 92, and the clevis
63 is automatically closed by the connecting pin 65. At the same time, the rotation piece 103 abuts the lock piece 105 to prevent the rotation in the direction of opening the recess 95c, so that the clevis 95
Is automatically closed by the lock piece 105. Thus, the carrier-side upper connecting member 61 and the container-side upper connecting member 11, and the carrier-side lower connecting member 91 and the container-side lower connecting member 16 are automatically connected to each other. Then, as shown in FIG. 6B, the front part of the container 1 is lifted by the carrier-side upper connecting member 61 through the container-side upper connecting member 11, and at the same time, the rear part of the container 1 is supported. It is lifted by the member 3 as follows. That is, since the container-side lower connecting member 16 is stationary with respect to the ground by the stationary carrier-side lower connecting member 91, when the container-side lower connecting member 16 rises, the container-side lower connecting member 16 is moved relative to the container main body 2. It moves down relatively and its movement projects downwards by the chain 21 and the chain 40, raising the rear part of the container 1. That is, the front part of the container 1 is pulled up by the container-side upper connecting member 11 and the rear part is raised by the supporting member 3, and the movements thereof are synchronized, so that FIG.
As shown in, the container 1 rises in the horizontal direction. When the main girder 32 provided at the bottom of the main body 2 of the container 1 is at the same level as the level of the subframe 47 of the carrier 45,
The operation of the hydraulic cylinder 71 on the carrier side is stopped. At this time, the column device 51 is in the state shown in FIG. 5 (b). The ascending movement of the column 1 is stopped, the hydraulic motor is driven to move the column device 51 forward, and the container 1 is moved forward in the same manner as shown in FIG. 6 (c). At this time, the rear part of the container 1 is supported on the ground by the roller 7 at the lower end of the support member 3, and the front part of the container 1 is supported by the carrier-side upper connecting member 61 and the carrier-side lower connecting member 91. And, it is pulled via the container side lower connecting member 16. Then, after the horizontal movement of the container 1 is completed, the container 1 is moved to the carrier.
The hydraulic cylinder 71 is contracted while it is placed on 45. At this time, since the carrier-side upper connecting member 61 is connected to the container-side upper connecting member 11, the container-side upper connecting member 61 is connected.
Held at a height of 11. Therefore, the tube 71b is vertically restrained by the lower chain 85 and the upper chain 84,
It is kept at the same height. Therefore, as shown in FIG. 5 (c), the tip of the piston rod 71a rises away from the pedestal 48 of the vehicle body 46, and the carrier-side lower coupling member 91 coupled to the tip of the piston rod 71a is raised. To be Then, similarly to the case shown in FIG. 6 (d), the container-side lower connecting member 16 engaged with the carrier-side lower connecting member 91 is raised, and the supporting members 3 are pulled up from the ground by the chains 21 and 40. To be The container body 2
The guide part 201 and the guide part 201
