Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a container carrier used primarily for transporting aircraft containers at airports.

[Conventional technology]

As an aircraft container carrier used at an airport, a horizontally rotatable turntable is installed on a trolley that is connected to a towing vehicle and is towed, and the turntable is used to load or lower containers. A device equipped with a row of rollers is known.

[Problem that the invention attempts to solve]

However, since the roller row provided on the turntable is oriented in one direction with respect to the turntable, there is a restriction on the direction in which containers can be loaded and unloaded. In other words, although the turntable has a rectangular shape to match the shape of the bottom of the container, the loading and unloading direction of the container is almost constant, so even if the stopping position and direction of the transport vehicle are fixed. However, there have been cases where it has not been possible to stop at the desired stopping position and direction due to surrounding conditions.

[Means to solve the problem]

Therefore, in the present invention, the roller rows are arranged in two directions, one direction with respect to the turntable and the other direction perpendicular thereto, and one of the roller rows is placed at a higher position and a lower position than the other roller row. The present invention is characterized in that it is supported so as to be movable, and its vertical movement is linked to the rotational movement of the turntable.

[Effect]

With this structure, the present invention allows containers to be loaded and unloaded from both the vertical and horizontal directions of the turntable.Moreover, the raising and lowering of the row of rollers that can be raised and lowered is performed in conjunction with the rotation of the turntable, making it easier to operate. becomes easy.

Rotating shafts 18, 18 having vertically moving rolls 17 that come into contact with the back surface of the roller frame 7c are disposed below the roller frame 7c, and these rotating shafts 18, 18 are connected to brackets 19, 1.
The link arms 20, 20 are interlocked and connected via the link arm 9. Then, the vertically moving roll 17
In the upright state as shown in the figure, the vertical feed roll row in the central portion 7a is higher than the height of the horizontal feed roll row 6, is at the same height as the end portion 7b of the vertical feed roller row, and rotates approximately 90 degrees. When it collapses, the central part 7
The height of the roll row a is lower than the height of the transverse feed rolls 6. This vertical movement roll 1
When 7 is laid down, rotation is prevented by the stopper 21. The intermediate portions of the link arms 20, 20 are pivotally connected to a pair of swing arms 22, 23 via pins 24. The swinging arms 22 and 23 have their respective bases pivoted to the pivot parts 25 and 25 so as to be horizontally rotatable, and their respective tips move while remaining in contact with each other up to a predetermined angle, as shown in detail in FIG. A cam roller 26 is provided at the tip of the swing arm 23 so as to project downward. A cam 27 projecting upward from the truck 1 contacts the cam roller 26 when the turntable 5 is orthogonal to the truck 1, and the swinging arms 22, 23 are connected to each other as shown by the solid line in FIG.
