Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a cargo conveyance method and apparatus.

[Conventional technology and its problems]

Conventionally, it has been customary to use buckets to transport bulk materials such as steel raw materials. However, sling work is required to suspend the bucket 1- from the crane, and efficient work requires a total of four workers, two on both the loading and receiving sides.

However, the worksite is not only dangerous, but also has an extremely poor working environment, as the footing is poor on ships, on vehicles, in warehouses, and in loading yards, and a large amount of dust is produced. Furthermore, in addition to simply transporting the bucket, the bucket is turned upside down to release the cargo, which not only doubles the danger, but also requires both a main hoist hook and an auxiliary hoist hook. Single-hook cranes also required modification to add auxiliary hoists, which increased costs.

[Means for solving problems]

Therefore, in the present invention, all work other than loading, such as loading the bucket, transporting it, discharging the load by inverting the bucket, and restoring the bucket, etc., is performed only by the crane operator, and the lifting is done by the crane operator. It eliminates the need for a harvester, eliminates the danger of work, eliminates the need to work in poor environments, and performs extremely efficient and low-cost transportation work through automatic work. By lowering the hook, the mooring part for the bucket provided on the baracerato lifting tongs is lowered, and the mooring part is rotated by the drive source to be moored to the loaded bucket, and after being hoisted and transported by a crane,
A method for transporting pickled vegetables characterized by releasing one side of the latching part at the destination, tilting the bucket by winding the crane hook, and releasing the transported goods, and a method of latching or fixing the bucket hanging tongs to the crane hook. In addition, the bucket hanging tongs are movably provided with a latching part for the bucket, and the latching part is connected to a drive source, while the bucket is provided with a latching part for the latching part. [Example] Next, the present invention will be explained in detail with reference to a specific example. .3 stand up.

It is a yellow indicator light. 42 is a control panel, 43 is a crane, and 44 is a crane hook. It is also possible to directly fix the hoisting rope of the crane 43 to the hook locking part 25 without using the crane hook 44.

Next, the method of use and operation will be explained. The crane hook 44 is lowered and suspended in the lock 4il112G of the hook locking portion 25. bucket hanging tongs l
The power is turned on via the control panel 42. At this time, the red indicator light 40 is turned on. The bucket lifting tongs 1 are lowered by lowering the crane hook 44 (Fig. 6 1), and the lifting guides 32, 32... The chevron-shaped piece 36 of the bucket 33 is guided and fitted into the groove 35 of the chevron. With this mating, the switch O
The NL yellow indicator light 41 is also turned on (Fig. 6, 2).

Therefore, the motor 7 is operated and the reducer 8. chain 45
The shaft 9 is rotated by the sprocket lO through the sprocket lO.

At that time, the small gear 22 fixed to the shaft 9 is rotated, and at the same time, the drive shaft J3 is rotated via the large gear 21 that meshes with the small gear 22.

As a result, the hook 12 set on the drive shaft 13 is rotated to bring the tip end to 1'111t. When lowering the hook 12, the alignment boss 16 allows the hook 12 to swing to the left (i) with respect to the axis. This hook 12 is designed to prevent the bucket 33 from moving.
When J2 reaches the lowest end, the locking rods 3B and 3g are stopped at a position where they can be locked, and the green indicator light 39 lights up (Fig. 6, 3). In the same way, the other hooks 12.12 are also locked:
Stop 18 and 38 at a position where they can be suspended.

Then, the bucket hanging tongs 1 are raised by an inching operation, and the hooks 12, 12, . . . hang the corresponding locking rods 3B, 38, . ). At this time, the yellow indicator light 41 is switched off and goes out.

Next, the bucket hoisting tongs 1 are raised -E by a single hoisting operation, and the bucket 33 is conveyed by traveling of the crane 43 (FIG. 6, 5). Land the bucket 33 at the destination,
The bucket lifting tongs 1 are further lowered to fit the chevron-shaped pieces 36 into the chevron-shaped grooves 35. At this time, the yellow indicator light 41 lights up. In this state, the hook 12.12 is attached to the locking rods 38, 38.
The engagement with... has been released.

Therefore, only one motor 7 is rotated and the shaft 9. The hook 12.12 on one side is rotated and raised by the shaft 13 (6th
Figure 6). Then, the - side green indicator light 39 goes out. When the bucket hanging tongs 1 is raised by the winding L operation, only the hook 12.12 on one side that cannot be rotated is locked to the locking rod 38.38 of the bucket seal, and the green indicator light 39 on the other side is connected to the fishing bucket. Pull up in one direction of 33. Further, by raising the bucket lifting tongs 1, the bucket seal is further tilted and the loaded cargo is dropped (FIG. 6, FIG. 7).

Also, one side of the bucket 33 is attached to the bucket hanging tongs-1,
For example, it is also possible to use a U-shaped hook or to pivotally connect it so that it can be rotated but not separated. In this case, the same operation can be accomplished by operating only one hook 12.12.

In the above, one mode of discharging bulk materials has been explained. It is also possible to load the equipment.

Alternatively, it is of course possible to expect a similar conveyance without using the bucket 33 and by having the locking rod protrude from the cargo.

Furthermore, it is of course possible to suspend the bucket lifting tongs ↓ directly on the lifting lobe without using the crane hook 44, thereby creating a crane exclusively for bucket lifting tongs.

In this case, the auxiliary hooks 37, 37 can be used to perform general cargo handling work.

〔Effect of the invention〕

As described above, according to the present invention, by lowering the crane hook, the mooring part for the bucket provided on the baracerato lifting tongs is lowered, and the mooring part is rotated by the drive source to be movable to the loaded bucket. At the same time, after being hoisted and transported by a crane, at the destination, one side of the latching section is unlatched, the bucket is hoisted by the crane hook, the bucket is tilted, and the transported object is released, so the bucket is slung onto the crane hook.

Preliminary work such as transport, overturning the bucket, releasing the load, and returning the bucket to its original state can only be done by the crane operator. As a result, slinging, which previously required two eutectic workers on the loading and receiving sides, is no longer necessary, eliminating environmentally hazardous and dangerous work, and making it possible to carry out efficient work at extremely low costs.

Furthermore, in the case of a single hook with an auxiliary winding, it was necessary to modify the hook to attach an auxiliary winding when the bucket overturned, but this is no longer necessary with the present invention. In addition, the device itself is extremely simple, can be used in ordinary cranes, and is inexpensive, so it has great practical effects.
