Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention enables a spreader device used for promptly lifting a shipping container in a container yard or the like to be used for both a standard container and a large container. The present invention relates to a spreader device for a container equipped with a corner flipper and a side flipper.

[Conventional technology]

Conventionally, standard containers for ships that have been generally used include those with lengths of 20, 35, 40, and 45 ㎛, all of which have a uniform width dimension of 8 ㎛. The spreader device used for hoisting is one spreader device for each length container by adjusting the telescopic frame that can expand and contract in the length direction through the chain driven by the hydraulic motor. It was enough to deal with.

In such a spreader device, at the bottom of the four corners,
After inserting into the long holes provided at the four corners of the container
There is a twist lock that locks by twisting 90 °, and guides called corner flippers are provided at the lower parts of the four corners of the spreader device for use in aligning this twist lock with the long hole of the container. ing.

However, in recent years, as a special large-sized container other than the above-mentioned standard container, for example, a large container having a length of 48-ga and an 8-ga 6-ga width of the American President Line has been developed and used.

As described above, even in a large container with a width of 8 inches and 6 inches, the position of the slot into which the twist lock is inserted is 45 inches long and 8 inches wide.
It is the same as the position of the hole in the standard container of the rabbit. For example, as shown in FIG. 8, struts 2 are exposed in the middle of both ends of a large container 1 having a length L of 48 g, and the length 1 between these struts 2 is the length of a conventional standard container. For example, the length is 45 ㎛, and moreover, at the upper part of these stanchions 2, inside the full width W of this large container 1 = 8㎎6 inch,
Elongated holes 3 for inserting twist locks are provided at the same intervals as the standard container having a width of w = 8 liters.

Therefore, the above-mentioned large-sized container 1 cannot be handled by the corner flipper provided in the conventional spreader device for a standard container, and it takes time to align the twist lock of the spreader device, which lowers the container lifting work efficiency. There is a problem of doing.

[Problems to be solved by the device]

The present invention has been made in order to solve the above-mentioned conventional problems. In addition to the standard container size, it can accommodate a large container width with a wide container width, but the mechanism is simple and the number of parts is also small. It is an object of the present invention to provide a spreader device for a container that is less in number and excellent in economical efficiency and maintainability.

[Means for solving the problem]

As a means for solving the above problems, the container spreader device of the present invention is provided with movable frames slidable in the longitudinal direction at both ends of a fixed frame, and twist locks are provided on the lower surfaces of the corners of the movable frame. In a spreader device for a container, which is provided with a corner flipper for a standard container size that can be set in a downward guide position and an upward storage position on the upper surface of the corner part, a large-sized container with a wide container width is provided at the corner part of the movable frame. The feature is that a dedicated side flipper that supports only the container is pivotally supported.

As described above, a corner flipper guides the twist lock for a standard container, and a large flip container is guided by a side flipper while the corner flipper is stored in a large container. It is possible to guide the twist lock alignment to the container in a short time.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall perspective view of a spreader device for a container according to an embodiment of the present invention, FIG. 2 is a side view of the spreader device, and FIG. 3 is a plan view of the spreader device. When hoisting, insert the twist locks 5 provided at the bottoms of the four corners into the long holes provided at the tops of the four corners of the container (not shown), and then twist by 90 ° to lock and lock the container with this spreader device. It is lifted by a crane.

Further, this device is composed of a fixed frame 6 at the center and telescopic frames 7 on both sides in the length direction thereof, and is extendable and contractible in the length direction E through a chain 9 driven by a hydraulic motor 8. , Its stretched state is second
It is indicated by a two-dot chain line in the drawings and FIG.

Therefore, as shown in FIG. 2, the twists provided at the four corners of the conventional standard container of 20, 35, 40, and 45 hogs are expanded and contracted in the direction of arrow E and locked according to the length of each standard container. With the four corner flippers 10 for the lock guides set in the downward guide state, the alignment for the twist lock guides of the standard container is performed.

An enlarged view of the corner flipper 10 at the guide position is shown in FIG. 6, and the corner flipper 10 guides the vertical columns at the four corners of the standard container to provide the long length provided on the upper portion of the twist lock 5 container. Alignment with holes can be performed.

Next, when not using this corner flipper 10,
Using the pin portion 11 shown in FIG. 7 as a fulcrum, it is pulled up to the upper portion of the spreader as shown in FIG.

That is, the corner flipper 10 is provided so as to be vertically rotatable between the downward guide position and the upward storage position of the spreader, and is locked by a stopper or the like at each of these positions. There is.

Next, as shown in FIG. 8, for example, the length L is 48
In order to apply this spreader device to a large container 1 having a total width W of 8 inches and 6 inches, the corner flipper 10 is raised to the storage position and is held on the side of the spreader device. The twist lock 5 is rotated by 180 ° in the lateral direction R of FIG. 1 so that the side flipper 13 in the storage position shown in FIGS. Is used as a guide for alignment with the long holes 3 provided at intervals of the width w of the columns 2 on the upper portion of the large container 1 in FIG.

That is, at the guide position of the side flippers 13, the distance between the pair of side flippers 13 in the width direction corresponds to the total width W of the left and right columns 2 provided in the middle of both sides in the length direction of the large container 1. The size of the side flipper 13 is such that the side flipper 13 is locked by a stopper or the like at the storage position and the guide position, though it functions as a twist lock position adjustment for the large container 1.

The corner flipper 10 and side flipper
At each storage position, 13 is stored within a range that is sufficiently within the plane size of the container to be suspended so that it will not be an obstacle when this spreader device goes in and out of a ship's hold.

[Effect of device]

As described above, according to the present invention, the movable frame that is slidable in the longitudinal direction is provided at both ends of the fixed frame, the twist lock is provided on the lower surface of the corner portion of the movable frame, and the downward guide is provided on the upper surface of the corner portion. In the spreader device for containers equipped with a corner flipper for standard container size that can be set in the storage position and the storage position facing upwards, the corner part of the movable frame is equipped with a dedicated side flipper that supports only large containers with a wide container width. Since it is rotatably supported, it can be used not only for standard size containers, but also for large containers with a wide container width, but the mechanism is simple, the number of parts is small, and it is economical and easy to maintain. It is extremely useful for improving cargo handling efficiency.
