Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to equipment for unloading earth and sand from a catamaran carrier.

The conventionally known unloading equipment from a catamaran carrier is related to the loading and unloading of extremely heavy objects such as molten iron and molten steel. When a guidance wharf with a guide and a catamaran carrier straddle it, the upper surface is lowered one step from the upper surface of the guidance wharf so that the loading platform guidance guide and that of the guidance wharf are continuous, and the upper surface is lowered to the sea side following the guidance wharf. It consists of a combination of a ship wharf extending over the
(See Publication No. 694).

However, due to the structure of such cargo unloading equipment, it is not possible to unload large quantities of earth and sand for landfill, garbage for disposal to artificial islands, and ores transported by sea.

The purpose of this invention is to provide a cargo unloading facility that can transport the above-mentioned earth and sand by sea using a catamaran carrier, and can reliably unload the earth and sand that has been carried in combination with this carrier. be.

This invention will be described in detail below based on embodiments shown in the drawings.

The unloading equipment from a catamaran carrier according to this invention is as follows:
A cargo receiving structure 2 that is built to protrude into the sea at a predetermined distance from
It consists of a duct 3 that communicates with the hollow interior and two rows of belt conveyors 4 that run from the bottom of the cargo receiving structure 2 through the duct 3 to the shore 1, and the cargo receiving structure 2 is a twin-hulled belt conveyor 4. It is formed to a size that can be straddled by the mold carrier 5, and a large number of bottom-opening poppers 11 equipped with opening/closing plates 12 are continuously provided within the surrounding wall 10 and above the conveyor 4. be.

The catamaran carrier 5 is self-propelled and includes a bottom-opening hopper 7 between the catamaran hulls 6.

The entire hopper 7 has two rows on the left and right in a rectangular shape when viewed from the plane in the longitudinal direction of the center of the ship, but a plurality of bulkheads 8 are provided at predetermined intervals, and a pair of left and right rows are provided for each compartment. An opening/closing plate 9 is provided.

The cargo receiving structure 2 is a rectangle that is long in the direction of the coast 1 when viewed from above.

The hoppers 11 are arranged in two rows on the left and right, and the front and rear opening/closing plates 12 are connected to the piston rond of the fluid pressure cylinder 13, as shown in FIG. It is designed to open and close.

Although not shown, the opening/closing plate 9 of the catamaran carrier 5 can be automatically opened and closed by a hydraulic cylinder in the same way.

In the above, to explain the case of unloading earth and sand, first, the catamaran carrier 5 is placed astride the cargo receiving structure 2, and then the opening/closing plate 9 of the hopper 7 of the catamaran carrier 5 is placed astride the cargo receiving structure 2.
is opened in the direction of the arrow in FIG. 3, and the earth and sand loaded therein are allowed to fall into the cargo receiving structure 2.

When the earth and sand are transferred to the cargo receiving structure 2, the opening/closing plate 12 of the hopper 11 is opened in the direction of the arrow in FIGS. 3 and 5, and the earth and sand are allowed to fall from the hopper 11 onto the conveyor 4.

Ru.

The earth and sand on the conveyor 4 passes through the duct 3 and is lifted to the shore 1.

Although not shown, the cargo receiving structure 2 is provided with a lid.

A roll-up type lid is best.

It is also convenient to submerge the base 1 of the duct 3 into the sea to the extent that the catamaran carrier 5 can pass over the cargo receiving structure 2 and change direction.

The unloading equipment from a catamaran carrier according to this invention is as follows:
A cargo receiving structure 2 built to protrude into the sea at a predetermined distance from the cargo receiving structure 2;
and the coast 1 and communicates with the hollow interior of the cargo receiving structure 2, and a conveyor 4 that runs from the bottom of the cargo receiving structure 2 through the inside of the duct 3 to the coast 1.
Therefore, the cargo receiving structure 2 is formed to a size that can be straddled by the catamaran carrier 5, and its surrounding wall 10
Since a large number of bottom-opening hoppers 11 equipped with opening/closing plates 12 are installed in a continuous manner inside the conveyor 4 and above the conveyor 4, the earth and sand are once removed from the catamaran carrier 5 as described above.
After being transferred to the cargo receiving structure 2, the cargo can be reliably unloaded using the conveyor 4 inside the hollow part.
Since the conveyor 4 passes through the duct 3, it is also advantageous in terms of pollution problems.
