Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heavy load / unload device for a continuous unloader. For example, loading and unloading coal, ore, and other bulk materials in a boat by a continuous unloader that uses a bucket elevator is performed by continuously driving the bucket at the scraper of the unloader. When the thickness becomes thin, or when the bulk material remains in the corner of the ship's hold, a bulldozer is carried into the ship's hold, the bulk is scraped by the bulldozer, and then unloaded by an unloader. And, the continuous unloader is also used for loading and unloading the bulldozer into the ship's hold. Also, if loose material adheres to the reinforcing material on the side wall of the ship's side, similar to the above, a heavy machine for scraping off the loose material on the side of the ship's wall and a heavy machine for washing off the adhered bulk on the side of the ship's wall by spraying water inside the ship's side It is necessary to carry in. Further, in addition to the above-mentioned heavy equipment, various heavy equipment needs to be carried in and out of the ship's hold. The present invention relates to a heavy load / unload device used in such a case. In the present specification,
"Heavy goods" refers to bulldozers, heavy equipment, and other heavy equipment.

[0002]

2. Description of the Related Art A conventional heavy goods loading / unloading apparatus for loading / unloading a bulldozer or the like by a continuous unloader will be described with reference to FIG. In the figure, 5 is a continuous unloader UL
With the scraping part of, the hanging piece 51 is attached at the appropriate place,
Connect four sling wire ropes (henceforth sled wires 52) for hanging the bulldozer to this suspension piece 51,
Bulldozer B was going up and down.

[0003]

However, the conventional example has the following drawbacks. Ie sling wire
It is necessary to manually transport 52 to the bulldozer B and the hanging piece 51, but if the unloader UL becomes large, not only the sling wire 52 becomes longer and heavier, but also the hanging point on the hanging piece 51 side becomes higher and the ground ( It will not be possible to install it directly from the bottom. For this reason, it is necessary to use a special equipment for mounting the sling wire 52, but even if it is used, the operability is poor and the labor is enormous.
Moreover, since a plurality of bulldozers are usually used, it is necessary to replace the sling wires 52 on the quay and inside the boat each time, so the labor is considerably large.

In view of such circumstances, the present invention greatly reduces the labor of slinging work for loading and unloading heavy objects such as bulldozers and other heavy machinery, and enables safe work in a short time.
It is also an object of the present invention to provide a heavy load carrying-in / out apparatus for a continuous unloader that does not require the use of special equipment.

[0005]

A heavy load carrying-in / out apparatus for a continuous unloader according to the present invention has a vertical transport unit for vertically transporting a bulk substance at the tip of a boom, and the bulk transport unit at the lower end of the vertical transport unit. In a continuous unloader provided with a scraping unit, a rope for suspending heavy objects, the base end of which is connected to an appropriate position of the scraping unit, and a lowering end of the rope for suspending heavy objects, whose lower end is freely connectable And the upper end of the sheathing wire rope is connected, and the sheathing wire rope can be wound and unwound freely, and the winder is installed at an appropriate position of the vertical transport unit. In the above-mentioned present invention, four ropes for suspending heavy objects and two ropes for sheathing wire are provided, and two ropes for suspending heavy objects are connected to both left and right side surfaces of the scraping unit, One winder is installed on each of the right and left sides of the vertical transport unit, and one right sheathing wire rope connected to the right winder is connected to two right heavy ropes. Thus, it is preferable that one left sheathing wire rope connected to the left winder is connected to two left heavy load ropes.

[0006]

In the present invention, during the loading and unloading work of the continuous unloader, if the tip of the rope for suspending heavy objects is connected to the lower end of the sheathing wire rope and the sheathing wire rope is wound up by the winder, the heavy object can be suspended. The hanging rope can be hung up at a high position that does not interfere with the scraping work at the scraping section. When suspending heavy objects,
When the winding wire rope is unwound by the winder, the rope for suspending heavy objects can be hung down on the ground or on the bottom of the ship, where the tip of the rope for suspending heavy objects is removed from the lower end of the rope for suspending heavy objects. It can be connected to the suspension bar. In this state, if the boom of the continuous unloader is raised and lowered and turned, heavy goods can be loaded and unloaded. In the present invention, the manual work is performed only by connecting the heavy object hanging rope that has come down to the ground surface (bottom surface) to the heavy object hanging rope at a low position, and transports the wire rope on the ground or in the ship's hold. Since it is not necessary, the labor is greatly reduced,
Moreover, since there are few wire rope connection points, it is possible to reduce slinging time and loading / unloading time of heavy objects. Further, according to the configuration in which the two ropes for suspending the heavy object are arranged on the right and left sides, the heavy object is hoisted in a balanced manner, so that it is possible to carry in and out in a stable state.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a side view of a heavy load carrying-in / out apparatus 10 according to an embodiment of the present invention, FIG. 2 is a front view thereof, FIG. 3 is an enlarged view thereof, and FIG.
FIG. 3 is an explanatory diagram of a continuous unloader UL to which the present invention is applied.

First, a continuous unloader to which the present invention is applied
The UL will be described with reference to FIG. 4. 1 is a traveling frame, 2 is a swivel base, 3 is a boom that can be raised and lowered, and 4 is a vertical transport unit that vertically transports loose objects (an example is a bucket elevator continuous unloader, Hereinafter, referred to as a bucket elevator) 5 is a scraping portion, 6 is an elevator casing, and these are known configurations. Loading / unloading device 10 of the present invention
Is attached using the scraping part 5 and the elevator casing 6.

The structure of the loading / unloading device A will be described with reference to FIGS. Reference numeral 7 is a scraping frame of the scraping unit 5.
On each of the left and right sides of the scraping frame 7, two bases of heavy-weight suspension ropes 11 (referred to as heavy-weight suspension ropes; hereinafter the same) are connected by shackles, etc., and a total of four weights are attached. Suspended rope 11 is prepared. And
At the tip of this heavy object rope 11,
A shackle 12 for connecting with 17 (referred to as a sheathing wire rope; the same applies hereinafter) and for connecting with the suspension bar of the bulldozer B is attached.

On the other hand, a mounting floor 8 is formed at an appropriate position of the elevator casing 6, and a winding machine 13 is installed on each of the left and right sides of the mounting floor 8. This winder 13
A known device including a motor 14, a speed reducer 15 and a drum 16 may be used. An upper end of a sheathing rope 17 is connected to the winding drum 16 of each winding machine 13, and an intermediate portion thereof is wound up, and a connecting fitting 18 is attached to a lower end of the sheathing rope 17. The connecting fitting 18 may be an iron plate-like fitting in which a hole for the bolt of the shackle 12 is formed, or the same shackle as the shackle 12. A guide 20 for passing the sheathing rope 17 may be provided, and the guide 20 may be attached to the elevator casing 6 or the scraping section 5 at an appropriate position.

Next, the hoisting and carrying work of the bulldozer according to this embodiment will be described. The work is carried out in the order of FIGS. The state shown by the solid line in FIG. 5 (I) is a state in which the heavy object lifting rope 11 is lifted up through the sheathing rope 17, and the scraping work by the unloader UL is performed in this state. When the winding machine 13 is driven and the sheathing rope 17 is lowered, the heavy object hanging rope 11 is lowered to the ground (or the bottom of the ship) as shown by the dotted line. Figure 5 (II) shows a heavy lifting rope 11
The shackle 12 is removed from the sheathing rope 17 and the sheathing rope 17 is wound up. This leaves only the heavy load rope 11 on the ground. Then, as shown in FIG. 6 (III), the boom is hoisted and swung to raise the scraping unit 5 to move it directly below the bulldozer B, or the boom is hoisted to raise the scraping unit 5 and The bulldozer B is moved below the scraping unit 5, and the shackle 12 of the heavy load rope 11 is connected to the suspension bar of the full dozer B. This work can be performed with a light force because the tip of the heavy load rope 11 is down to the suspension bar of the bulldozer B, and since it is not necessary to carry any suspension equipment, the labor is small.

In FIG. 6 (IV), the boom of the unloader UL is raised and lowered, the bulldozer B is lifted and swung, and the ground (berth) is shown.
It shows the state of moving from to the bottom of the ship and vice versa. In this case, bulldozer B has four heavy lifting ropes.
Since it is supported by 11 points at 4 points, it can be stably lifted and the transportation work is safe. As shown in FIG. 7 (V), the bulldozer B is lowered to the target position on the ship bottom or the quay, the heavy load rope 11 is slightly slackened, and the shackle 12 is removed. Then, the winder 13 is driven to lower the sheathing rope 17. As shown in FIG. 7 (VI), the boom is hoisted and swung to move the scraping unit 5 or the bulldozer B, and the heavy load rope 11 is connected to the seeping rope 17. As shown in FIG. 8 (VII), the winding rope 13 is used to wind up the sheathing rope 17, and the heavy object lifting rope 11 is lifted up to its original position and stored. As a result, the state returns to FIG.

As described above, according to this embodiment, the unloader UL is always provided with the heavy load rope 11,
Since there is no need to transport the heavy lifting rope 11 on the ground or onboard, it is no longer necessary to attach the heavy lifting rope 11 to the lifting piece on the unloader side at a high place. The number of connecting points of the rope 11 is reduced and the slinging time can be shortened and the work efficiency is improved.

Although the carrying-in / out of the bulldozer B has been described in the above embodiment, the same procedure can be applied to heavy equipment such as heavy equipment other than the bulldozer B and other heavy equipment. Further, in the above-mentioned embodiments, the present invention is applied to the bucket elevator unloader, but the present invention can also be applied to a continuous unloader in which the vertical conveyor is a double belt sandwich type or a screw conveyor type.

[0015]

According to the present invention, in the manual work, the rope for suspending heavy objects that has come down to the ground surface (bottom surface of the ship) is simply connected to the suspending rope for heavy objects at a low position, and the wire rope is connected. Since it does not need to be transported on the ground or on the boat, labor is greatly reduced, and since there are few wire rope connection points, slinging time and loading / unloading time of heavy goods can be shortened. Therefore, the loading and unloading of heavy objects between the ground and the bottom of the ship by the continuous unloader can be safely performed in a short time with a small amount of labor.
