Description

[Detailed Description of the Invention] The present invention relates to a container fixing device for a container transportation trolley.

Containers, especially aviation containers, are provided with engagement grooves on both sides of the lower part, and when mounted on a trolley, the container is fixed by engaging a holding device provided on the trolley with the engagement groove of the container. That's what I do.

Incidentally, containers are loaded onto carts by loaders, but the direction in which the containers are loaded is not constant and changes depending on the loader.

Therefore, the holding device on the trolley must be able to hold containers no matter which direction they are loaded.

The present invention seeks to provide a holding device that can hold containers stacked in one direction and acts as a guide for containers stacked at a 90 degree displacement in the other direction.

Explaining the following with reference to the drawings, in Figs. 1 and 2, 1 is a container transport trolley, and 2 is a turntable rotatably supported on the trolley, on which containers can be easily loaded. Therefore, a large number of rollers 3 are provided.

Container holding devices 4 are provided at both ends of the roller row in the transfer direction.
is provided.

The holding device has protruding pieces 7 that engage with engaging grooves 6 provided on both sides of the lower part of the container 5, and is provided so that the entire holding device is buried in the turntable when not in use.

Holding devices A according to the present invention are provided on opposite sides of the roller row.

As shown in FIGS. 3 and 4, this device is installed symmetrically at both ends of two shafts 9 that are slidably supported on the frame 8 of the turntable, and is fixed to the ends of the shafts. It has a receiving plate/guide plate 12 supported by an end support plate 10 and a support plate 11 fixed to a shaft inside the frame 8, and a holding plate 13 is rotatably supported on this.

That is, the shaft 14 fixed to the lower side of the holding plate 13 is connected to the guide plate 12.
It is rotatably inserted into a hole provided in the shaft, and a removal stopper plate 15 is fixed to the shaft end, and a U-shaped guide plate for rotating and fixing...
The bundle 16 is slidably inserted into a hole 17 provided in the guide plate 12, and the tip of the bundle is inserted into a hole 18 provided in the guide plate 12, and the guide plate is fixed by the bundle so as not to rotate. There is.

In the state shown in FIGS. 3 and 4, the engagement end 13a of the holding plate 13 is in a holding position in which it protrudes inward, and from this state the bundle 1
6 and remove the tip of the handle from the hole 18 of the guide plate 12, the holding plate will be able to rotate freely.

Therefore, when the holding plate is rotated 180 degrees by the bundle,
The engaging end 13a of the holding plate is located on the outside, there is no protrusion inside the turntable, and it is on the same plane as the end surface 12a of the guide plate 12.

Next, the operation when loading a container will be explained.

As shown in FIG. 5, when the container is loaded onto the turntable with the engagement groove 6 of the container 5 positioned in the front-rear direction, the holding plate 13 is placed in the retracted position and the guide plate 12 guides the loading of the container. to play the role of

At this time, the pair of left and right holding devices are connected by a shaft 9,
Since the distance between the end plate 10 and the frame 8 shown in FIG. 4 can move together in the left and right directions, it is possible to compensate for slight positional discrepancies between the container and the holding device, as shown by the chain lines in FIG. can be guided by the holding device following the movement.

After loading, the holding device 4 is raised and the protruding piece 7 is engaged with the engagement groove 6 to hold the container.

When loading a container with the engagement grooves 6 positioned on the left and right sides as shown in FIG. 6, the holding plate 13 is placed in the protruding position as shown in the figure, and is engaged with the engagement groove 6 to hold the container. be able to.

As is clear from the above, according to the present invention, one set of devices acts as a holding device or a guide device depending on the loading direction of the container, so separate devices are required for each function. There is no need to provide a , and the configuration can be simplified.
