Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sediment transport apparatus suitable for water transport of landfill soil, dredged soil, and the like.

(Prior Art) Conventionally, for example, the transportation of landfill sand to the sea is generally carried out by using an earth transporter, but there is a certain limit to the amount of transportation, and expansion of the landfill scale is not possible. There was a problem that we could not respond. Further, for example, in the case of transportation of dredged soil, generally, a transportation pipe was arranged on the sea and the slurry was transported through the transportation pipe by driving a dredging pump.However, the inner surface of the pipe is greatly worn and a large amount of water is contained. However, there is a problem in that the post-processing is troublesome because it is included in.

Therefore, various studies have been made to utilize a belt conveyor which is frequently used on land as a transportation means in place of the above-mentioned soil transportation or slurry transportation. For example, in Japanese Patent Publication No. 51-45152, there is mutual vertical swing or horizontal movement. A floating conveyor has been proposed in which a common belt conveyor is arranged on a plurality of floats that are swingably connected.

(Problems to be solved by the invention) However, according to the above-mentioned conventional floating conveyor, since a general-purpose flat belt is used as a belt conveyor to be mounted on the float, a plurality of base belts are used when changing the direction (curving). There is the trouble of having to transfer the belt conveyor of many times, and in addition to this, because both sides of the belt are open, the float tilts due to the influence of waves, etc. However, there is a problem in that it is difficult for the soil to be transported stably because the soil easily falls off from the belt.

The present invention has been made to solve the above-mentioned conventional problems. The purpose of the present invention is to change the direction in the middle of the water, to reduce the restrictions on use, and to realize stable mass transport of earth and sand. It is to provide an earth and sand transport device.

(Means for Solving the Problems) In order to solve the above problems, the present invention connects a plurality of floats floated in a row on the water so as to be horizontally rotatable with respect to each other. Is provided with a common belt conveyor having a U-shape, and the belt conveyor divides the conveyor frame into float units, and
The gist is that each conveyor frame is provided with a guide roller that guides the belt in a U-shaped cross section.

(Operation) In the above-mentioned waterborne earth and sand transport device configured as described above,
Since the belt is guided in a U-shaped cross section, the belt easily follows the direction in which the floats are arranged, and the belt conveyor can be bent at any position. Also, the walls on both sides of the belt can cover the earth and sand to prevent the earth and sand from being scattered to the outside.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 to FIG. 5, 1 is a plurality of floats floated in a row on the water, and each float 1 is made up of two drums 2, 2 arranged in a twin barrel type, which are integrally connected by a fixed frame 3. ing. One side (end side) 2 of each float 1
The two floats 1a and 1b are straight pipes 4 and 4 provided at one end of each.
Butt and fixedly connected, other floats 1c, 1d,
1e ... are connected to each other so as to be rotatable in the horizontal direction and slightly rotatable in the vertical direction by connecting the hinges 5, 5 provided at one end thereof with a pin 6.
Figure). A support frame 7 extending between the drums 2 and 2 is provided at an appropriate position on the upper surface of each float 1 (Fig. 3), and the belt conveyor 10 is provided above the float 1 with the support frame 7 as a scaffold. Is provided.

The belt conveyor 10 is formed by disposing a common endless belt 12 inside a conveyor frame 11 having a divided structure, and is arranged in the middle of both drums 2 and 2 in order to maintain the balance in the left-right direction. Further, in the belt conveyor 10, the portions corresponding to the two floats 1a and 1b on the one side are inclined.
The tip of this inclined portion serves as a discharge port for earth and sand, and the entire length of this inclined portion is formed by an integral conveyor frame 11, and the two floats 1a, 1b that are directly connected to each other are connected.
By supporting with, the rigidity in this range is increased and it is considered that it can be stably connected to other work equipment. The other parts of the conveyor frame 11 are each float 1
Is divided according to. A pavement plate 8 is laid on the upper surface of each float using the support frame 7, and a handrail (not shown) provided on the pavement plate 8 can guide a person to move.

As shown in detail in FIG. 5, the belt conveyor 10 divides the inside of the conveyor frame 11 into upper and lower sections, and holds the ears 13 at both side ends of the belt 12 in the upper section by sandwiching the belts 12.
Is a U-shaped cross section, first guide rollers 15 and 15 are in contact with both side surfaces of the U-shaped belt 12, and third guide rollers are in contact with the lower surface of the belt 12. , And the first and second guide rollers 14 and 15 excluding the third guide roller 16 are arranged on the lower stage.
Are installed. However, the belt 12 has an inverted U-shaped cross section on the lower side. The belt 12 includes these guide rollers 14,1
It is guided while maintaining a U-shape by 5, 16 and rotates the upper and lower stages in the conveyor frame 11 endlessly. Belt 12
Is hung on the driving roller or the driven roller 17 (FIG. 1) at both ends of the belt conveyor 10, but in this part, it is released from the guide rollers and becomes flat (FIG. 2), so that it can be easily inverted. Has become.

Hereinafter, the operation of the above-described earth and sand transport device will be described by taking the case of using it for landfill as an example.

First, a large number of floats 1 are connected and floated on the water. The float 1a (Fig. 1) on one side of the float 1 is brought close to the landfill and extended to a seawall (not shown). After mooring them with anchors, Build belt conveyor 10 on top. The belt conveyor 10 may be composed of one line, but may be divided into a plurality of lines for transfer if necessary. In the case of division, one side of the belt conveyor is lifted to an inclined state as shown in FIG. 1, and this inclined portion is wrapped on the other side of the partner belt conveyor. In transporting earth and sand, first, the belt 12 is rotated by driving the driving roller 17, and earth and sand are put into one end of the rotating belt 12.
At this time, since one end of the belt 12 is flat,
As with a general-purpose belt, it is possible to easily add earth and sand. Immediately after loading the soil, the belt 12
It is guided to the U-shaped groove of and is transported to the landfill where both sides are covered with the wall of the belt 12. Therefore, for example, even if the float 1 is greatly inclined due to the influence of waves or the like, the earth and sand are not scattered from the belt 12 and can be stably transported.

In the case where the belt conveyor 10 needs to be bent due to the layout, each float 1 is horizontally rotated by a predetermined angle as shown by a virtual line in FIG. By the rotation of the float 1, the conveyor frame 11
Although the direction is changed by a predetermined angle, the belt 12 is U-shaped, so that the direction is easily followed, and the direction of the belt conveyor 10 is adjusted.

Note that the present invention can be applied to the transportation of various types of sediment other than the above-mentioned landfill sediment, but when applied to the transportation of dredging sediment, for example, it is possible to transport a large amount of sediment in a drained state, so post-treatment It will be easier and the cost of dredging will be reduced.

(Effects of the Invention) As described in detail above, according to the above-mentioned water transporting apparatus for water and sand, one belt conveyor can be bent at any position in any direction, The degree of freedom in designing the water transportation line is significantly improved, and the installation is extremely simple. In addition, it is possible to prevent the sediment from being dissipated during transportation, and it is possible to obtain the effect of significantly improving the stability of sediment transportation.
