Description

[Detailed Description of the Invention] [Field of Use of the Invention] The present invention relates to a container guide structure, and more particularly to a container guide structure for easily loading or unloading a container to or from a chassis in a container crane.

[Prior art]

In a container crane, there are operations for loading and unloading containers from a chassis for transporting containers.

That is, as shown in FIG. 11 in the container yard,
The container 2 transported by the ship 1 is loaded on the chassis 4 by the container crane 3 and transported by the chassis 4 to a predetermined position in the yard.

By the way, such container cranes are usually large
Since the height thereof is several tens of meters, it is difficult to align the trolley 5 and the chassis 4 with each other, and if the spreader 6 for hoisting the container 2 is swinging due to the influence of wind or the like, its position is swayed. Since the matching work is difficult, it takes a long working time, and the cargo handling efficiency is poor.

Therefore, it is conceivable to provide a guide device for aligning the chassis 4 and the spreader 6. As the guide device, for example, Japanese Patent Publication No. 54-31273
The one shown in the issue is known. However, since this guide device is fixed on the ground, there is a problem that the cargo handling position is limited, and therefore there is a practical problem.

[Purpose of device]

The present invention has been made to solve the problems of the above-described conventional device, and the purpose thereof is not limited to the loading position of the container crane, but the container can be easily attached to the chassis. The point is to improve the cargo handling efficiency by carrying out loading and unloading.

[Outline of device]

The container guide device according to the present invention supports a trolley 15 having a spreader 16 on the upper part of the main body of a container crane 11 so as to traverse freely on a horizontal beam, and is movable along a horizontal beam 17 provided below the horizontal beam. In the device supporting the above, the guide device 19 has a plurality of supports 21 arranged at intervals on both sides in the longitudinal direction of the container, and a vertical member for guiding the container at the lower end of the support 21.
25 supports the tilting member 23 at the lower end, and further supports the support member 21.
The vertical member 25 and the vertical member 25 are connected by a connecting member 30, and the lower end portion of the support body 21, the vertical member 25, the tilting member 23, and the connecting member 30.
And a parallelogrammatic link mechanism are formed by the guide device 19 and the guide device 19 is expanded and contracted by the drive device 26 so that the support member 21
It is configured to be individually swingable with respect to.

At the lower end of the
Is installed.

A plurality of such guide mechanisms 34 are provided in the longitudinal direction of the frame 35 (the direction orthogonal to the lateral beam 17), and each guide mechanism 34 has a rope 46 as shown in FIG. The interval L can be adjusted by the operation of the. That is, depending on the length of the container 14, the container 14 can be moved along the frame 35.

A guide 47 is attached to the second support 33 by a pin 48 and is rotated about the pin 46 by a drive device 49. The guide 47 is used for positioning the container 14 in the longitudinal direction. .

(Embodiment 3) FIG. 9 shows a further embodiment of the present invention, in which a horizontal beam 50 is supported at both ends by a pillar 51 to be erected, and a guide mechanism 52 is provided on the horizontal beam 50.
A support body 53 having the above is suspended by a roller 54 so as to be movable in the longitudinal direction of the cross beam 50.

It should be noted that in this embodiment, by setting the guide mechanism 52 in advance at an arbitrary position of the column 51, it is possible to easily load and unload the containers 14 on the chassis 27.

[Effect of device]

The container guide structure according to the present invention supports a trolley 15 having a spreader 16 on the upper part of a container crane 11 main body so that it can traverse freely, and a plurality of guides can be moved along a horizontal beam 17 provided below the horizontal beam. In the device supporting the device 19, the guide device 19 includes a plurality of supports 21 arranged on both sides in the longitudinal direction of the container at intervals.
A tilting member 23 that supports a vertical member 25 for guiding the container at the lower end is supported at the lower end of the support member, and the lower end of the support member 21 is further connected by a connecting member 30 between the support member 21 and the vertical member 25. A parallelogrammatic link mechanism is formed by the section, the vertical member 25, the tilting member 23, and the connecting member 30, and the guide device 19 is individually swung with respect to the support body 21 by the expansion and contraction of the drive device 26. It is configured to be possible.

Therefore, the guide device 19 is fitted to the container 14 on the chassis 27 or the chassis 27. Then, the tilting member 23 and the vertical member 25 of the guide device 19 act as guides and
It is possible to accurately load 14 on the chassis 27 while guiding it (Figs. 1 to 4).

The guide device 19 of the present invention forms the guide surface of the container 14 by the tilting member 23 and the vertical member 25, and this guide surface can be individually adjusted according to the posture of the chassis 27 located below the container crane 11. The container 14 can be accurately positioned on the chassis 27.

Similarly, when the container 14 on the chassis 27 is lifted, the tilting member 23 and the vertical member 25 form a guide surface for the container 14 to be lifted.

Therefore, the loading and unloading operations of the container 14 to and from the chassis 27 can be performed accurately and quickly.

In particular, in the present invention, since the chassis 27 is moved in accordance with the position of the container crane 11 to be loaded and unloaded, it is not necessary to perform loading and unloading at a specific location. The efficiency can be significantly improved.

Note that the reference numerals are given according to the first embodiment, and in the case of other embodiments, they should be read according to this.
