It is characterized by.

  Further, a locking and unlocking fixture 22a is formed on an upper portion of one side surface of each upper column 22, and the locking and unlocking of each upper column 22 is performed with the opening / closing door 20 closed. The locking and unlocking cylinders 41 that are positioned close to the fixture 22a and are fixed to the barge body 10 are slid by the locking and unlocking cylinders 41, and the locking and unlocking cylinders 41 are slid. A locking and unlocking means 40 each comprising a locking and unlocking piston coupled to and separated from the locking fixture 22a to lock and unlock the upper column 22 of the door 20; To feature.

  Note that a pump is provided on the upper portion of the barge body 10 so that seawater flows into or drains into the air chamber 12 so that the buoyancy can be adjusted by the weight of the aggregate accommodated in the aggregate accommodating portion 11. 50; is further provided.

  In addition, a buoyancy auxiliary air sac 60 that can be attached to and detached from the lower part of the air chamber 12 of the barge ship body and adds buoyancy to the barge ship body 10 is further provided on both sides of the lower part of the air chamber of the barge ship body 10. Further, a detachment prevention plate 13 is further provided which can be folded by being hinged to the buoyancy assisting air bag 60 so as to prevent the buoyancy auxiliary air sac 60 from detaching.

The present invention closes the open / close door by an opening / closing means, and loads the aggregate to be stored in the aggregate receiving portion provided in the barge ship main body using a hoist or the like, and the barge ship main body is moved to the dropping place. After that, the aggregate is laid by opening the open / close door with the opening and closing means and dropping the aggregate stored in the aggregate storage section all at once into the water without using a separate hoist. There is a tremendous advantage that the time taken for laying can be greatly shortened, thereby shortening the construction period.

  Furthermore, since the aggregate is dropped into water all at once, the present invention is very advantageous in a place where the water force is fast. Moreover, since the opening / closing means for driving the opening / closing door is installed on the upper side of the barge, corrosion from seawater can be minimized, and repair is easy.

  In addition, even when the particle size of the aggregate is small, such as sand, the molding force between the aggregates is reduced so that the side surface shape of the aggregate container is inclined or a semi-arc structure. Aggregate accommodated in the material accommodating portion can be easily dropped onto the lower part outside the barge ship body.

  In the present invention, when the aggregate is accommodated in the aggregate accommodating portion, it can be stacked high like a truck, and a large amount of aggregate can be accommodated. Alternatively, when the aggregate is loaded on the aggregate accommodating portion, the opening / closing door is inclined from the lower stage to the lower portion of the aggregate accommodating portion, so that a larger amount of aggregate can be accommodated. In both cases, since the opening / closing door is inclined from the lower stage to the lower part of the aggregate housing portion, the impact of the aggregate on the opening / closing door when dropping the aggregate can be reduced.

  In addition, since the opening and closing door is formed in a lattice shape and many parts of the aggregate accommodated in the aggregate accommodating part are operated so as to be immersed in water, the load of the aggregate accommodated in the aggregate accommodating part Can be reduced, and can respond stably to waves. In addition, reducing the load on the aggregate improves the mobility of the barge, and reduces the capacity of the motor, engine, etc. that drive the barge. Alternatively, since the aggregate is dropped in a state where many parts of the aggregate are immersed in water, it is possible to reduce the impact applied to the open / close door when the aggregate is charged.

  In addition, it is possible to prepare for an emergency such as a failure occurring by installing three or more open / close means on the open / close door.

  In addition, when heavy aggregate is loaded or when the aggregate is loaded high on the upper part of the aggregate housing, it is stable by increasing the buoyancy of the barge using a removable buoyancy-assisted air sac. Loading is possible.

  In addition, when the height of the embankment in which aggregate is piled in the water located in the lower part of the barge ship main body 10 is high, the buoyancy is further increased in the barge ship main body 10 by the buoyancy auxiliary air sac 60, so that the barge ship main body 10 is increased. The aggregate can be thrown into the water surface as much as possible. As a result, the embankment can be loaded at a maximum height, and the entire construction period due to the accumulation of the embankment can be shortened.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  Hereinafter, an aggregate input device using a barge of the present invention will be described with reference to the accompanying drawings.

FIG. 5 is a cross-sectional view showing an operating state of the aggregate charging device using the barge ship according to the present invention, and FIG. 6 is an operating state of the buoyancy assist air sac of the aggregate charging device using the barge ship according to the present invention. FIG. 7 is a view showing the locking and unlocking means of the aggregate input device using the barge ship according to the present invention, and FIGS. 8 to 9 use the barge ship according to the present invention. It is the top view which showed the aggregate injection apparatus.

  The aggregate input device using the barge ship of the present invention is roughly divided into a barge ship body 10, an opening / closing door 20, and an opening / closing means 30.

  The barge body 10 is provided with a square-shaped aggregate accommodating portion 11 penetrating vertically at the central portion at the upper portion, and air chambers 12 at lower portions on both sides of the aggregate accommodating portion 11. In addition, the barge body 10 is provided with a known drive device for sailing in the same manner as a general ship.

  Since the above-mentioned aggregate accommodation part 11 is in the state where the upper part was opened, when accommodating aggregate in aggregate accommodation part 11, it can pile up like a truck and can accommodate a lot of aggregates. An opening / closing door 20 is provided at the lower stage of the aggregate housing part 11.

  It is preferable that the inside of the air chamber 12 is inclined from the upper part to the lower part so that the area of the aggregate housing part 11 increases from the upper part to the lower part.

  When the particle size of the aggregate is small like sand, the aggregates stored in the aggregate storage part 11 generate cohesive force with each other, and the aggregate remains in the aggregate storage part 11 when dropped. be able to. Therefore, if the inner side of the air chamber 12 is formed so as to be inclined from the upper part to the lower part, the aggregate contained in the aggregate containing part 11 is transferred to the outside of the barge ship body 10. Dropping becomes easy.

  Thus, even when the aggregate particle size is small, such as sand, the forming force between the aggregates is reduced, and the aggregate shape of the side wall of the aggregate container is inclined or an arc-shaped structure. Aggregate accommodated in the accommodating portion can facilitate dropping to the outside of the barge ship body.

  At this time, a plate that is coupled to the door main body 21 and closes the gap between the horizontal member 21a and the vertical member 21b so that a small aggregate such as sand can be accommodated in the aggregate accommodating portion 11 ( (Not shown).

  A reinforcing bar is provided on the inner side wall of the barge body 10 that forms the aggregate housing part 11 in the form of a square bar that is spaced at a constant interval, so that the aggregate housing part is accommodated when the aggregate is housed and dropped. 11 to prevent the inner wall of the barge ship body 10 from colliding with the aggregate and being damaged.

  The opening / closing door 20 is positioned at the lower stage of the aggregate housing portion 11 and is hinged to the barge body 10 so as to be pivotable. The aggregate housing portion 11 accommodates the aggregate or the aggregate housing portion 11. It performs the role of opening and closing so that the aggregate accommodated in the container is dropped.

  The open / close door 20 is hinged to the lower side of the aggregate housing part 11 of the barge ship body 10 so as to be rotatable and can be integrated.

  The opening / closing door 20 can be divided into two on both sides.

  In the drawing, the opening / closing door 20 is hinged to both sides of the lower part of the aggregate housing part 11 of the barge ship body 10 so as to be pivotable, and the portion located between the hinge pivoting shafts is pivoted on the hinge. It was shown that it was divided into two with the same size parallel to the axis.

  The open / close door 20 includes a door body 21, an upper column 22, and a hinge coupling portion 23.

  The door body 21 is rotated so that the aggregate is accommodated in the aggregate accommodating portion 11 or the aggregate accommodated in the aggregate accommodating portion 11 is dropped.

  The door body 21 is preferably installed so as to incline from the lower stage to the lower part of the aggregate container 11.

  In addition, when loading the aggregate in the aggregate accommodating portion, the opening / closing door is inclined from the lower stage to the lower portion of the aggregate accommodating portion 11, so that a larger amount of aggregate can be accommodated. In both cases, since the opening / closing door is inclined from the lower stage to the lower part of the aggregate housing portion 11, the impact of the aggregate on the opening / closing door 20 when dropping the aggregate can be reduced.

  The upper column 22 is formed integrally with the upper portion of the door main body 21 and is installed at a predetermined interval. The upper column 22 is coupled with the opening / closing means 30 and is rotated so that the door main body 21 is rotated. To do.

  The hinge connecting portion 23 is provided at a portion where the door main body 21 and the upper column 22 are connected, and is hingedly connected to the barge ship main body 10 positioned at the lower stage of the aggregate housing portion 11.

  In the opening / closing door 20, it is preferable that the upper column 22 and the door body 21 form an obtuse angle. The reason why the upper column 22 and the door body 21 form an obtuse angle is to facilitate the operation of the opening and closing means.

  Aggregate is accommodated in the aggregate receiving portion 11 with the open / close door 20 closed, and in order to receive the aggregate, the aggregate is dropped into the aggregate accommodating portion 11 using a hoist or the like. To be. After moving the barge to the place where the aggregate is dropped in such a state, the opening / closing door 20 is opened so that the aggregate stored in the aggregate storage portion 11 is dropped all at once. To do.

  Thus, the present invention is advantageous where the water force is fast because the aggregate is dropped into water all at once by opening the door 20.

  Further, the door main body 21 of the open / close door 20 is installed in the same direction as the rotational axis direction of the door main body 21, and is installed with a lateral member 21 a spaced apart at a predetermined interval, and the rotational axis of the door main body 21. It is preferably made of a vertical member 21b that is installed in a direction perpendicular to the direction and spaced apart at a constant interval, and is in a lattice shape so that seawater can flow into the aggregate housing part 11.

  As described above, when the door body 21 of the open / close door 20 has a lattice shape and seawater flows into the aggregate housing part 11, much of the aggregate housed in the aggregate housing part 11 is obtained. Therefore, the load of the aggregate accommodated in the aggregate accommodating part 11 can be reduced, and it can respond to a wave stably. Further, by reducing the load on the aggregate, the mobility of the barge ship is improved, and the capacity of the motor, engine, etc. that drive the barge ship can be reduced. Alternatively, since the aggregate is dropped in a state where many parts of the aggregate are immersed in water, it is possible to reduce the impact applied to the open / close door 20 when the aggregate is charged.

  Further, when the aggregate door 11 is loaded with aggregate in the aggregate accommodating portion 11, the open / close door is inclined from the lower stage to the lower portion of the aggregate accommodating portion 11, so that a larger amount of aggregate can be accommodated. However, when the amount of aggregate is small, the aggregate can be loaded in the aggregate housing portion 11 with the door body 21 of the open / close door 20 positioned horizontally. As described above, when the door body 21 of the open / close door 20 is positioned horizontally, the fork-shaped protrusions 21c are formed so that the ends of the door bodies 21 are engaged with each other. To do.

  As shown in FIG. 9, when the aggregate housed in the aggregate housing part 11 is dropped by opening the opening / closing door 20, the upper part of the upper pillar 22 is dropped while the aggregate located above the upper pillar 22 is dropped. In order to prevent the aggregate from impacting the upper stage of the upper column 22 and allowing it to fall along the inclined surface to the lower side, the triangular shape is formed behind the upper column 22. The impact preventing portion 22b is provided. The impact prevention unit 22b also serves to prevent the aggregate from penetrating behind the upper column 22 when the aggregate is dropped.

  The opening / closing means 30 opens and closes the opening / closing door, and includes a motor 31, a rotating shaft 32, a wire 33, and a pulley 34 as shown in FIGS. 3 to 5 and 7 to 9. .

  The motor 31 is installed in the upper part inside the barge body 10.

  The rotating shaft 32 is connected to the motor 31 to rotate and is provided with a winding unit 32a that winds a wire.

  One end of the wire 33 is connected to the winding portion 32a and wound or unwound by the rotation of the rotating shaft 32, and the other end is connected to the upper step of the upper column 22 and wound. The upper pillar 22 is rotated by being taken or unwound. When the wire 33 can be unwound, the door body 21 is turned by its own weight, and the upper column 22 formed integrally with the door body 21 is turned.

  The pulley 34 is wound around the wire 33 and fixed to the barge ship body 10 located behind the upper column 22, and the wire 33 is wound or unwound according to the rotation of the rotating shaft 32. The upper column 22 is rotated by being pulled or unwound.

  At this time, the opening / closing means 30 is installed at the upper part of the barge body 10 adjacent to the upper column 22.

  Thus, since the opening / closing means for driving the opening / closing door is installed on the upper side of the barge ship, corrosion from seawater can be minimized and repair can be easily performed.

  Although the opening / closing means 30 of the present invention is described as being actuated by winding the wire 33 using the motor 31, other forms of opening / closing means may be used to open and close the opening / closing door. For example, it is possible to use a chain instead of a wire, an opening / closing means using a hydraulic or pneumatic device using a cylinder and a piston, an opening / closing means using a gear, or the like.

  The upper column 22 is installed at three or more places at a certain interval in the length direction of the opening / closing door 20, and the wire 33 of the opening / closing means is also installed at three or more places so as to prepare for an emergency. Is preferred.

  7 and 8 with the opening / closing door 20 closed, if the rotating shaft 32 is rotated by the rotation of the motor 31 and the wire 33 can be unwound as shown in FIG. The upper column 22 is rotated about the hinge coupling portion 23 by the weight of the door main body 21 below the aggregate housing portion 11, and the door main body 21 is opened so that the aggregate Aggregate accommodated in the accommodating portion 11 drops and drops down along the door body 21 of the open / close door 20.

  As described above, according to the present invention, the opening / closing means 20 is closed by the opening / closing means 30 and the aggregate is received in the aggregate receiving portion 11 provided in the barge ship body 10 using a hoist or the like. After the barge ship body 10 is loaded and moved to the drop-off place, the opening / closing door 20 is opened by the opening / closing means 30 without using a separate hoist or the like, and the aggregate stored in the aggregate storage portion 11. However, since the aggregates are laid by dropping them into the water all at once, the time required for laying the aggregates is shortened, and the construction period can be shortened.

  3, 5 and 7 show a state in which the door main body 21 is in a horizontal state and the lower stage of the aggregate housing portion 11 is closed, and FIG. 8 shows the bone in a state in which the door main body 21 is inclined downward. The state which the lower stage of the material accommodating part 11 was closed is shown.

  In FIG. 8, the rotating shaft 32 is rotated by the rotation of the motor 31 in the state of FIG. 7 and the wire 33 is unwound, but the end of the protruding portion 21c formed at the end of the door body 21 is engaged with each other. A state in which the lower part of the aggregate housing part 11 is closed is shown.

  As shown in FIG. 8, when the lower stage of the aggregate housing part 11 is closed with the door body 21 inclined downward, the amount of aggregate housed in the aggregate housing part 11 is as shown in FIG. More than the amount of aggregate accommodated in the aggregate accommodating portion 11 shown in FIGS.

  As described above, the present invention allows the door body 21 to be positioned horizontally or tilted so that it can be variably adjusted depending on the amount of aggregate.

  When the amount of aggregate is small and the door body 21 is rotated from the state of FIG. 8 to the state of FIGS. 3, 5, and 7, the forks so that the end portions of the door bodies 21 mesh with each other. A protruding portion 21c having a shape is formed. FIG. 6 is a plan view of FIGS. 3, 5 and 7 showing that the protrusions mesh with each other.

  When the door main body 21 is installed to be inclined downward as shown in FIG. 8, the protruding portion 21 c can close the lower stage of the aggregate housing portion 11.

  7 and 8, when the rotating shaft 32 is rotated by the rotation of the motor 31 and the wire is completely unwound, the door body 21 is opened by its own weight as shown in FIG. As a result, the aggregate can be dropped into the water.

  When the opening / closing means 30 is inoperable, the opening / closing door 20 can be rotated and opened by its own weight. In such a case, a safety accident may occur in a state where the aggregate is stored in the aggregate storage portion 11.

  Therefore, in order to maintain the state in which the aggregate is accommodated in the aggregate accommodating portion 11, a lock and unlocking means 40 for maintaining the state in which the opening / closing door 20 is closed is provided. In both cases, a locking and unlocking fixture 22a is formed on the upper portion of one side surface of the upper column 22 of the opening / closing door 20.

  As shown in FIG. 3, the locking and unlocking means 40 includes a lock and unlocking cylinder 41 and a lock and unlocking piston 42.

  The lock / unlock cylinder 41 is fixed to the barge body while being positioned close to the lock / unlock fixture 22a of each upper column 22 with the open / close door 20 closed. The

  The locking and unlocking pistons 42 are slid by the respective locking and unlocking cylinders 41, and are coupled and separated from the locking and unlocking fixtures 22a to lock and lock the upper column 22 of the open / close door 20. Unlock.

  Further, the upper portion of the barge ship body 10 allows seawater to flow into the air chamber 12 or be drained so that the buoyancy can be adjusted by the weight of the aggregate accommodated in the aggregate accommodating portion 11. And a pump is further provided.

  When the aggregate is accommodated in the aggregate accommodating portion 11 of the barge body 10, a large amount of air is discharged by operating the pump inside the air chamber 12 to drain the seawater flowing into the air chamber. The buoyancy of the barge ship body 10 is increased so as to be satisfied by the above, and when the aggregate is dropped from the aggregate housing part 11 of the barge ship body 10 and is vacant, the pump 50 is operated to Seawater flows into the air chamber 12 and the buoyancy of the barge ship body 10 is adjusted by reducing the buoyancy of the barge ship body 10.

  When the aggregate loaded in the aggregate accommodating portion 11 is heavy, the buoyancy can be adjusted by using the buoyancy auxiliary air sac 60 (see FIG. 9) that adds buoyancy to the barge body 10.

  In this way, when a heavy aggregate is loaded or when a high aggregate is loaded on the upper part of the aggregate container, the buoyancy of the barge ship is utilized using the detachable buoyancy auxiliary air sac 60. As a result, the aggregate can be stably loaded into the aggregate accommodating portion 11.

  The buoyancy auxiliary air sac 60 can be attached to and detached from the lower part of the barge ship body 10 and plays a role of adding buoyancy to the barge ship body 10 and doubling it.

  When the height of the levee where aggregate is piled in the water located under the barge ship main body 10 is high, the buoyancy is further increased in the barge ship main body 10 by the buoyancy auxiliary air sac.
