Description

TECHNICAL FIELD The present invention relates to a container spreader equipped on a container crane, a transfer crane, a forklift, a straddle carrier, etc. on a quay or in a yard. .

(Prior Art) A conventional example of the container spreader used for cargo handling of a container will be described with reference to FIGS. 10, 11, and 12. The spreader frame (1) includes a fixed frame (1a) and a fixed frame (1a). ) Adjustable beam (1b) protruding from both sides
And an end beam connected between the ends of the beam (1b)
(1c), etc., so that it can be operated by being suspended by the main winding wire (2) of the crane, and the four corners of the spreader frame (1), that is, the end beams (1c) (1c). Twist locking devices (3) are projected below both ends of each of the end beams (1c) (1c), and the corner flipper guide (5a), guide roller (5b) and slide plate (5
Each of the twisting devices (3) is equipped with a corner guide mechanism (5) consisting of c), as shown in FIGS. 10 and 12, for example, in the width direction of the spreader.
(1c) A standard standard size container shown in Fig. 13 mounted at a position inside a distance (G ₁ ) from the end and at a position inside the distance (C) from the end of the end beam (1c) in the longitudinal direction.
The distance between the center of each receiving money (b) provided in (a) and the outer edge of the container (a) is equal, and when the spreader frame (1) is aligned and overlapped on the container (a). Each twist lock device (3) is structured so as to be aligned with each receipt (b) and connected to the container.

Further, each corner flipper guide (5a) is turned downward in the direction shown by the arrow in FIG. 10 to face downward to engage with each corner of the container (a) to align the spreader frame on the container. The guide roller (5b) and the slide plate (5c) play a role, and are arranged so as to engage with and guide the cell guide of the hold when the container is loaded.

In addition to the standard size container (a) shown in FIG.
Deformable size container (a ₁ ) formed long as shown in Fig. 4,
As shown in FIG. 15, there are long and wide deformation size containers (a ₂ ), etc., and the deformation size containers (a ₁ ), (a
_{In 2} ), the receiving money (b) is arranged at the same intervals as the standard size container (a), and the distance (E) from each receiving money (b) to the container edge (E),
The distance (G ₂ ) from each receipt (b) to the side edge of the container is longer than the standard size container (a) (c) and (G ₁ ), but the deformed size container (a ₁ ) In the present situation, the container spreader shown in FIG. 10 for standard size containers is also used in the cargo handling of (a ₂ ).

The spreader is provided with a telescopic beam, but there is also a beam fixed type.

(Problems to be solved by the invention) In the conventional spreader for a container, the spreader can be positioned on the container by a corner flipper guide for loading and unloading a standard size container, and the guide roller or the guide plate is guided to the cell guide of the hold. However, in the case of the deformed size container shown in FIGS. 14 and 15, the distance from each receiving member to the container edge and the container side edge is long, and the length D of the standard size container is
Since the deformed size containers are F and H ₂ with respect to the width H _1, there is a problem that the corner flipper guide, the guide roller, and the guide plate cannot perform the guide function.

(Means for Solving Problems) The present invention provides a spreader for a container for addressing the above-mentioned problems, in which a twister locking device that engages with a container money is provided at four corners. By providing a corner guide block that can be moved forward and backward from the four corners independently of the twist lock device, and by disposing a corner guide mechanism for the container on the corner guide block, the corner guide block can be made to correspond to the size of the container. The corner guide mechanism can be arranged at each corner portion of the container by advancing / retreating to eliminate the above-mentioned problems.

(Operation) When loading a standard size container, the corner guide block is retracted to the four corners of the spreader frame, and the corner guide mechanism provided in the corner guide block positions the spreader and holds the cargo in the same manner as before. It is used as a guide for the guide cells of the container, and when handling deformed size containers, the corner guide blocks are advanced from the four corners of the spreader frame according to the container size, and the corner guide mechanism is installed at each corner of the container. Correspondingly arranged, cargo handling is performed without corner guides as in the above.

(Embodiment) A first embodiment of the present invention is shown in FIGS. 1 to 4, in which (11) shows a fixed frame (not shown) and a beam (projected from both sides of the fixed frame). 11b) A spreader frame (stretchable or fixed) and an end beam (11c) fixed between the tip ends of the beam (11b), etc., which is suspended by a main winding wire. The spreader frame (11) Twist lock devices (3) are respectively provided at the four corners of the end beam (11c) (11c) below the ends of the end beams (11c) (11c) so as to be opposed to the container receiving money.

Further, as shown in FIG. 4, the four corners, that is, the upper surface of each end of the end beams (11c) and (11c) are formed into a plate-like sheet portion (1) formed inward and in the longitudinal direction of the spreader.
2) are continuously provided, and a guide rail (13) and a skid rail (1) oriented in the longitudinal direction of the spreader are provided on the seat portion (12).
4) (14) are provided in parallel, a corner guide block (15) having a groove (16) is fitted to the guide rail (13), the end beam (11c) and the corner guide block (15)
Connect the fluid pressure cylinder (17) with a bracket, pin, etc. between them, and use the fluid pressure cylinder (17) to guide the corner guide block (15) through the guide rails (13) and skid rails (14) (14). It is designed to be operated from the four corners of the spreader frame.

Further, a corner flipper guide (18a) and a guide roller (18b) are provided on the tip of the corner guide block (15) by pins (19) respectively, and guides are provided on the end face of the tip of the corner guide block (15). Plate (18c) (18
c) is provided and the corner guide mechanism (18) is provided.

The first embodiment of the present invention is configured as described above, and in the case of the standard size container (a) shown in FIG. 13,
Extend the fluid pressure cylinder (17) to retract the corner guide block (15) to the stroke end as shown by the solid line in the figure, and set the corner flipper guide (18a) and guide roller.
(18b) and guide plate (18c) to end beam (11c)
The corner flipper guide (18a) is rotated to form a downward chain line and can be placed in the corner of the standard size container (a) to position the spreader with respect to the container and the guide roller (18b). Alternatively, the guide plate (18c) is used as a guide for the cell guide of the hold.

Further, in the case of the deformed size container (a ₁ ) shown in FIG. 14, the tip of the corner guide block (15) moves from the end of the end beam (11c) to the spreader length due to the shortening operation of the fluid pressure cylinder (17). Of the corner guide block (18a), the guide roller (18b), and the guide plate (18c), i.e., the corner guide mechanism (18), which are arranged at the tip of the corner guide block (15) The container (a ₁ ) is brought into contact with a predetermined position corresponding to the corner portion of the container (a ₁ ), and can be guided by the corner guide mechanism (18) as described above. First
In the case of the embodiment, the standard size container and the deformed size container in the length direction can be used as cargo.

(Other Embodiment) FIGS. 5 to 9 show a second embodiment of the present invention, in which (11b) is a beam (expanding or fixing) which is projected from both sides of a fixed frame (not shown). ), (11c) is the beam
