Description

[Detailed description of the invention] The present invention relates to a soil lifting device, and its purpose is to lift up the entire barge to the landfill, for example, when unloading soil transported by sea by barge to a landfill. The purpose is to facilitate and speed up the unloading work.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a purge for transporting soil that has been transported by sea, and a soil discharge door 2 is provided at one end, for example, the front.

That is, the lower part of the door 2 is connected to the barge 1 via the shaft 3.
It is rotatably attached to the front part, and its upper side protrusions 2a are connected to winches 5 provided on both sides of the barge 1 via cables 4, so that they can be opened and closed forward.

6 is on the ground of the landfill 7 and underwater 8 below the barge 1
A guide body (for example, a pair of rails) is laid over the area, and the part from underwater 8 to the ground is an inclined part 6a having an inclination angle θ, and the part above ground is a horizontal part 6b.
is being used.

Reference numeral 9 denotes a truck which is movable on the guide body 6 by a hoisting device (for example, a winch) 10 and has a support portion 11 capable of horizontally supporting and fixing the barge 1 at the inclined portion 6a of the guide body 6. .

That is, the above-mentioned trolley 9 is connected to a hoisting device 10 provided on the ground via a cable (for example, a wire rope, a chain, etc.) 12.
It is connected to the.

Further, the support part 11 includes a contact part 13 that comes into contact with the bottom of the barge 1 to horizontally support the barge 1, and a corresponding contact part 13.
A fixing device 14 is provided at the front and rear of the barge 1 to fix the barge 1, and guide rollers 16 are provided which are attached to holders 15 provided at a plurality of locations on both sides of the barge 1 and guide the barge 1 onto the trolley 9. There is.

17 is a hopper installed in landfill 7, and barge 1
This is for guiding the soil discharged from the soil onto the discharge conveyor 18.

19, when the barge 1 was pulled up to the ground by the trolley 9,
This is a stopper for positioning the cart 9.

20 is a turning pulley for the cable body 12.

As shown in FIG. 2, when the barge 1 is pulled up to the ground by the trolley 9, the contact portion 13 of the trolley 9 that supports the barge 1 is at the same angle as the inclination angle θ of the inclined portion 6a of the guide body 6. Therefore, in order to discharge the soil loaded on the barge 1 with its own weight, the above-mentioned inclination angle θ is set to be greater than the angle of repose of the soil loaded on the barge 1.

According to the above configuration, the soil transport purge 1 transported to the sea near the landfill 7 is first horizontally supported on the trolley 9 located in the sea 8 as shown by the imaginary line in FIG. 2. Fixed with.

Then, the hoisting device 10 on the ground is activated, and the barge 1
Both the truck 9 and the truck 9 are pulled up in the direction of arrow A while keeping it horizontal.

When the truck 9 is pulled up to the horizontal part 6b on the ground, the barge 1 tilts at an angle of inclination θ, as shown by the solid line in FIG. 2, and the truck 9 is stopped by the stopper 19 at a position corresponding to the hopper 17. It will be done.

Then, when the soil discharge door 2 of the barge 1 is opened in the direction of arrow B, the loaded soil is naturally discharged into the hopper 17 as shown by arrow C.

The soil placed in the hopper 17 is transported to a predetermined location by a discharge conveyor 18.

After the soil has been discharged, the cart 9 and the barge 1 are moved back to the slope 6a by mechanical means, and then returned to the sea by their own weight.

In addition, a part of the ground is scraped off so that the bottom part does not come into contact with the ground when the cart 9 moves from the inclined part 6a to the horizontal part 6b of the guide body 6.

As described above, according to the soil lifting device of the present invention, the barge can be directly moved from the sea to the ground, and the barge can be tilted when on the ground, so all that is required is to open the soil discharge door of the barge. This allows the soil cargo to be discharged very easily and quickly.
