Description

[Detailed description of the invention] The present invention is a bridge type loader and a retractable crane two loader.

This invention relates to a swing suspension beam device that can be applied to bridge cranes, overhead cranes, etc.

FIG. 1 shows an overall view of a conventional bridge-type loader, and FIG. 2 shows a side view of FIG. 1. This crane is used to load cargo 4 from land into a cargo hold 6.It is used to load cargo 4 from land into a cargo hold 6.It is used to load cargo 4 from land into a cargo hold 6. Cargo is loaded into the hold 6 of the ship 5.

Further, FIG. 3 shows the configuration of a conventional hanging beam, and FIG. 4 shows a left side view of FIG. 3. In the figure, 7 indicates a wire rope for hoisting the bridge-shaped clay, 8 indicates a hook attached to the hanging beam 3, and 9 indicates a rope for slinging.

However, the conventional suspension beam has the disadvantage that not only can cargo be loaded within the width of the notch when loading cargo into the hold, but also the cargo cannot be turned. In addition, conventionally, when loading cargo under a deck in a ship's hold, the cargo was moved into the hold and then placed under the deck by a fireman. Furthermore, turning the cargo had to be done manually, which was extremely inconvenient and labor intensive. Therefore, there has been a demand for a swing suspension beam that can be loaded safely and efficiently using power.

The present invention has been proposed in response to the above-mentioned needs, and includes a head block suspended by a hoisting rope, a swingable head block provided at the bottom of the block, and a swingable head block that is rotatable from a motor on the block via a swing device. A hanging beam, a balanne beam fixed to the lower surface of the beam, having a balance weight at one end and extending laterally at the other end, and a hook attached to the other end of the beam for hoisting cargo. By using a balance beam, it is possible to suspend cargo at a position off the center of the suspension beam, and by suspending the balance beam below the swivel suspension beam, cargo can be suspended in any direction within the hold. It is an object of the present invention to provide a swinging suspension beam device that can accommodate the following.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 and FIG. 6 show a swing hanging beam according to an embodiment of the present invention.

In the figure, io is the head block.

Although not shown in this figure, by the four hoisting ropes 11,
It is suspended from a trolley as shown by numeral 2 in Fig. 2 at four points.

Reference numeral 12 denotes a swing suspension beam that is swingably attached to the bottom of the head block 1° via a swing device 13.

14 is a balance beam with a balance weight 15 at one end.
is provided with a hook 16 at the other end, and is detachably attached to the swing suspension beam 12 at a position near the balance weight 15 using four twist lock pins 17 on the swing amount beam 12. The hook 16 is attached to the tip of the balance beam 14, so that the load 4 can be lifted up. 18 is a turning motor provided on the hend block 10, 19 is a speed reducer, and 20 is an output gear, which meshes with the fixed gear 21 on the swing hanging beam 12 to rotate the swing hanging beam 12. .

Note that 5 is a cargo ship and 6 is a hold.

Next, to explain the operation of the embodiment configured as described above, the cargo 4 on land is lifted up by the hook 16 and placed in the hold.
Bring it inside. The cargo 4 carried into the hold 6 can freely rotate 360° by the rotation beam 12. Furthermore, when putting cargo under the deck, the cargo 4 is kept lifted to the deepest part of the hold 6 via the balance beam 14 even though the suspension beam 12 is within the hatch width as shown in Fig. 5. Can be imported.

The present invention is configured as described above.

The cargo can be loaded under the deck in the hold, and the cargo can be loaded in any direction by rotating the swing suspension beam.
