Description

[Detailed explanation of the idea] The present invention relates to an earth lifting device.

When disposing of the earth and sand transported by purging, for example, in a landfill, the biggest problem is how quickly the earth and sand can be disposed of.

In other words, if there is a landfill below the purge's stopping point, this purge can be carried out using a bottom removal method, but if the landfill is on the shore side, a packet crane or conveyor device must be used. The time it takes to lift the soil is enormous.

Furthermore, since the purge is in a floating state, the soil lifting operation becomes unstable.

The present invention proposes an earth lifting device capable of solving the above-mentioned problems when lifting earth to the shore side, and one embodiment thereof will be described below based on the drawings.

IA and IB are a pair of guide breakwaters erected from the seabed 2, and 3 is the guide breakwater IA.

18 shows a floating dock that can be raised and lowered and moved forward and backward.

This floating dock 3 has a tank 4 inside, and has support parts 6A and 6B on the left and right upper surfaces that can lift the purge 5, and a recess 7 with an open top between these support parts 6A and 6B. There is.

Furthermore, the floating dock 3 has overhanging parts 8A and 8B on both sides of the lower end, and these overhanging parts 8A and 8B are connected to the guide seawall IA.
, are fitted into notches 9A and 9B which have sufficient height in the vertical direction and are long in the front and back direction, and are formed inside the IB.

Since the overhanging portions 8A and 8B fit into the cutout portions 9A and 9B in this manner, the floating dock 3 can move up and down and move forward and backward within a certain range between the guide seawalls IA and IB.

At that time, the lower limit of the elevation is regulated by the lower surfaces of the overhangs 8A and 8B coming into contact with the lower step surfaces 10A and IOB of the notches 9A and 9B, and the upward root is regulated by the lower surfaces 10A and IOB of the notches 9A and 9B.
A plurality of idle rollers IIA arranged on the upper stage surface of 9B,
The upper surfaces of the projecting portions 8A and 8B come into contact with the projecting portion 11B, so that the projecting portions 8A and 8B are slidably regulated.

Note that the floating dock 3 is moved back and forth using a winch-type wire rope or by a self-propelled system.

One guide seawall 1A has a cutout part 13 with an open upper surface to allow movement of the operating part 12 integrated with the floating dock 3.

In addition, guide rollers 14A, 14B for guiding the movement of the purge 5 are provided on the inner surface of the upper end of the guide sea walls IA, IB.
is an array of multiple items.

The purge 5 is of a lower earth removal type, and the earth removal part 15 has a pair of left and right fixed bottom walls 16A, 1 facing diagonally downward to the center.
6B, and a pair of left and right movable bottom walls 17A and 17B diagonally downward and outward in the center, and these bottom walls 1
A ship capable of storing earth and sand 18 is formed above 6A, 16B, 17A, and 17B.

Reference numeral 19 denotes a floating conveyor device installed from the shore 20 to the guide seawalls IA and IB, and its starting end can plunge into the recess 7 of the floating dock 3 moving forward.

21 indicates the sea level. In FIGS. 1 and 4, the floating dock 3 is moved backward and separated from the floating conveyor device 19, and is further submerged by injecting water into the tank 4, so that the lower surface of the overhanging portions 8A and 8B is It is brought into contact with 10A and 10B.

In this state, the barge 5 is guided by the guide rollers 14A and 14B and moved between the guide seawalls IA and IB, and is stopped above the floating dock 3.

Thereafter, the inside of the tank 4 is drained, the floating dock 3 is raised, its support parts 6A and 6B are brought into contact with the bottom surface of the barge 5, and the barge 5 is moved to the sea surface 21 as shown in FIGS. 2 and 5. lift it up.

At this time, the concave portion 7 faces the earth removal portion 15, and the upper surfaces of the projecting portions 8A and 8B are brought into contact with the idle rollers IIA and IIB.

Next, the floating dock 3 is moved forward together with the barge 5, and as shown in FIGS. 3 and 6, the starting end of the floating conveyor device 19 is positioned within the recess 7 and opposed to the earth removal section 15.

In this state, move the movable bottom walls 17A and 17B to open the earth and sand 1.
8 is dropped onto the floating conveyor device 19.

The fallen earth and sand 18 are lifted onto the shore 20 by a floating conveyor device 19.

Note that by performing the above-mentioned reverse operation, the empty barge 5 can be floated on the sea surface 21 and towed.

As described above, according to the present invention, when the earth and sand in the barge is lifted to the shore side, the lower earth unloading section of the barge is moved to the starting end of the floating conveyor device while the barge is lifted by the floating dock. By positioning it above the section and opening the soil removal section in a closed position, falling soil can be lifted up by a floating conveyor system, which is faster and shorter than the conventional packet conveyor type. The soil can be lifted up.

Furthermore, since the floating dock on which the barge is lifted is prevented from rolling by a pair of guide seawalls, the above-mentioned soil lifting can be carried out stably under any sea conditions.
