DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ore fall prevention device attached to an unloader hopper used when wholesale ore and the like is unloaded from a wharf of an ironworks or the like.

[0002]

2. Description of the Related Art In a conventional unloader fall arrestor, an ore fall eliminator is provided on the ship side of a hopper such as an ore so as to be rotatable and deployable around a hinge shaft at a lower end as a fulcrum. To stop at.

[0003]

Considering that the ship moves up and down due to the high tide and the ship rises due to unloading, a gap must be provided between the side of the ship and the mining prevention plate. . Ore or the like leaked from the bucket often falls from the gap and pollutes the pier and the sea. The present invention is intended to prevent ores and the like from leaking through the gap between the port and the fallout prevention plate.

[0004]

The present invention will be described with reference to the drawings. The ore fall eliminator according to the present invention is provided with an ore fall elimination plate 20 on the ship 60 side of the ore hopper 12 so as to be rotatable and deployable around the hinge shaft 21 at the lower end as a fulcrum. An ore-dropping auxiliary plate 40 is provided so as to be rotatable and deployable with the horizontal hinge 41 provided at the edge as a fulcrum, and when the ore-prevention plate 20 is turned and stopped at a position close to the port 61, the ore-dropping auxiliary plate 40 is A winch which is configured to maintain a horizontal position on the ship 60, and a supporting frame 47 is extended from both ends of the mineral-removal auxiliary plate 40 in the direction of the mineral-removal prevention plate 20 and fixed to the side of the mineral-removal prevention plate 20. The wire 46 extending from 42 is passed through a sheave provided at the tip of the support frame 47, and the falling mine auxiliary plate 40 is always given an outward downward turning force by gravity, and when the wire 46 is wound up, the falling mine auxiliary plate 40 is formed. Rotate inward upwards,
When the wire 46 is rewound, the falling rock auxiliary plate 40 is configured to rotate downward.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 70 is a wharf, 60 ore carrier, 61 is a ship 6
A side of 0, 10 is an unloader, 13 is a machine frame of the unloader 10, 11 is a bucket, and 12 is a hopper.

[0006] The mining fall prevention plate 20 is pivotally supported at its lower end to the machine frame 13 by a hinge shaft 21. The winder 2 is mounted on the machine frame 13.
2, the first steel cable 23 and the second steel cable 24 are attached, and the falling steel plate 20 is provided with the support arm 28 and the third steel cable 25 is attached. The steel rope 26 coming out from the winding machine 22 is engaged with the second steel rope 24 via the first steel rope 23, the second steel rope 24, the third steel rope 25, the second steel rope 24, and the third steel rope 25. Is being worn.

Support frames 47 extend in the direction of the falling mine prevention plate 20 from both side ends of the falling mine auxiliary plate 40 pivotally attached to the upper edge of the falling mine prevention plate 20 by horizontal hinges 41. Brackets 48 and 49 projecting like wings are provided at the extended end of the support frame 47.

A support 27 is provided near the lower end of the ore fall-preventing plate 20 so as to protrude laterally, and a winch 42 is attached to the support 27. The first sheave 43 is provided on the upper side of the ore fall prevention plate 20 by disposing the support arm 28, the second sheave 44 is provided on the bracket 48, and the third sheave 45 is provided on the bracket 49. ing. The wire 46 exiting the winch 42 passes through the first sheave 43, the second sheave 44, and the third sheave 45, or the first sheave 43 and the third sheave 45 depending on the position of the fallen plate 40.
-It is bound to the ore fall prevention plate 20 near the first sheave 43 via the second sheave 44. Then, the falling rock auxiliary plate 40 is subjected to a downward force with the hinge 41 as a fulcrum due to gravity. Further, tension is always applied to the wire 46, and when the wire 46 is wound, the dropping auxiliary plate 40 is connected to the hinge 41.
Is pivoted upward with the fulcrum as a fulcrum, and if unwound, the ore drop assisting plate 40 is pivoted downward with the hinge 41 as a fulcrum.

[0009]

The position A in FIG. 4 is the position during the unloader operation. At the start of the work, first, the mineral-mineral assisting plate 40 is turned upward at this position, and as shown in a position D, the mineral-mineral assisting plate 40 is brought to the horizontal position. Next, set the minefall prevention plate 20 to port 6.
Stop at a position close to 1. During the unloader operation, if the falling ore auxiliary plate 40 is held in the horizontal position on the ship 60 as shown in the position C, ore and the like will not leak from between the port 61 and the prevention plate 20. The ore or the like deposited on the upper surface of the ore fall assist plate 40 is recovered toward the ore fall preventive plate 20 by rotating the ore fall assist plate as shown in the position B.

[0010]

According to the present invention, it is possible to reduce the amount of ore and the like leaking from the side of the ship 61 to the ore-prevention plate 20 and from a part of the deck of the ship to the pier 70 and into the sea. , And prevent pollution.
