Description

[Technical Field]

[0001] The present invention relates to a leveling barge equipped with a blade for leveling the bottom surface of the water, for example, in the sea or a river. [Background technology]

[0002] When leveling the bottom surface of the sea, river, etc. during dredging work, conventionally, as shown in Figures 7 and 8, an H-beam 3 suspended by a wire 2 from a leveling barge 1 is used as a blade 5, and the blade 5, which extends in the width direction (left and right direction) of the leveling barge 1, is moved forward in the leveling direction to level the uneven bottom surface.

[0003] Here, if the sediment on the bottom of the water is soft (silty), the blade 5 can scrape away the sediment well, but if the sediment is hard, the blade 5 will float up or rotate, preventing the sediment from being scraped away. For this reason, the weight of the blade 5 is increased by pouring concrete 4 into the H-shaped steel 3, or, as shown in Figure 9, the blade 5 is constructed by connecting four H-shaped steel pieces 3 with concrete 4 poured in them.However, even with this, the depth of the blade 5 may become unstable due to the blade 5 floating up or rotating, and construction may not be successful.

[0004] In contrast to this, as shown in Figure 10, a blade 15 is known which has a plate-shaped tip portion 12 fixed to the tip side of a main body portion 11 and multiple claw portions 13 spaced apart in the width direction at the lower end of the tip portion 12 (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4700761 Summary of the Invention [Problem to be solved by the invention]

[0006] Leveling the bottom of the water using the blade 15 shown in Figure 10 can prevent the blade 15 from floating up or rotating, but it only scrapes away the sediment on the bottom of the water, so although it can eliminate differences in the unevenness of the bottom of the water, it cannot smooth out the bottom surface. Furthermore, since the bottom is only leveled and not compacted afterwards, it is likely that unevenness will occur again over time.

[0007] Therefore, an object of the present invention is to provide a leveling barge that can more neatly level the bottom of the water by applying rolling compaction. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a leveling barge (100) in which one end (21) of a pair of left and right arms (20, 20) is rotatably attached to both left and right ends of the hull at the front side in the leveling direction, and the other end (22) is located underwater, and a blade (30) for leveling the bottom of the water is attached between the arms (20, 20) at the other end (22), and a wire (50) extending from a winch (40) provided at the rear side in the leveling direction of the hull has its tip fixed to the other end (22) of the arms (20, 20) or the blade (30), and the height position of the blade (30) in the water can be adjusted by changing the length of the wire (50), The blade (30) a main body (31) attached between the other ends (22) of the pair of left and right arms (20, 20) so as to be rotatable relative to the arms (20, 20), and having a receiving surface (31a) on its front surface, which is the front side in the smoothing direction; a plurality of cutting claw portions (32) provided at intervals in the left-right direction at the lower end of the receiving surface portion (31a) provided on the main body portion (31); The cutting tool is characterized by being provided with a rolling section (33) which is provided at the rear lower part of the main body section (31), has a curved surface (33a) protruding downward, and rolls the soil and sand cut by the cutting claw section (32).

[0009] The present invention is also characterized in that the cutting claw portion (32) is inclined downward from the rear side in the leveling direction to the front side in the leveling direction, and a space (Q) is provided between the cutting claw portion (32) and the rolling portion (33).

[0010] In addition, the present invention is characterized in that the main body portion (31) is inclined upward from the rear side in the leveling direction to the front side in the leveling direction.

[0011] The present invention is also characterized in that when the receiving surface portion (31a) of the main body portion (31) is in a vertical position, the tip position (P) of the cutting claw portion (32) is lower than the lowest surface position (S) of the rolling portion (33).

[0012] In addition, the present invention provides a method for adjusting the weight of a hull by adjusting the weight of the hull, the wires (50, 50) extending from the left and right rear sides of the hull in the leveling direction in correspondence with the pair of left and right arms (20, 20), The tip of the wire (50) is bifurcated, one (51) being connected to the upper front part of the main body (31), and the other (52) being connected to the upper rear part of the main body (31).

[0013] The symbols in parentheses above indicate corresponding elements or items described in the drawings and in the detailed description of the invention to be described later. [Effects of the Invention]

[0014] According to the leveling barge of the present invention, the blade that levels the bottom of the water is attached to the other end of a pair of left and right arms attached to the hull, and its height position underwater is adjusted via a wire.It is equipped with a main body with a receiving surface on the front, multiple cutting claws, and a rolling section, so that as the leveling barge moves forward in the leveling direction, unevenness in the bottom of the water is scraped away by the cutting claws, and the scraped soil and sand is received by the receiving surface, and as the leveling barge moves further forward, the bottom of the water is leveled horizontally. The horizontally leveled bottom surface of the water is then compacted by a compacting section having a curved surface protruding downward, so that the bottom surface of the water is compacted and maintained in a neat, horizontal state for a long period of time.

[0015] In the conventional example shown in Figures 7 to 10, the unevenness of the bottom surface of the water is simply scraped away, without any idea of ​​subsequently compacting it to make it level and level, so it is not possible to achieve a neat finish.However, in the present invention, the blade scrapes away the unevenness with the cutting claw section, and then immediately compacts it with the compacting section, so it is possible to level the bottom of the water more neatly and maintain that level state for a long period of time.

[0016] Furthermore, according to the present invention, the cutting claw portion is inclined downward from the rear side in the smoothing direction to the front side in the smoothing direction, so that irregularities on the water bottom surface can be sharply cut away. Furthermore, a space is provided between the cutting claw portion and the rolling portion, so that the soil scraped by the cutting claw portion enters the space and is successfully rolled by the rolling portion even if there is a large amount of soil.

[0017] Furthermore, according to the present invention, the main body is inclined upward from the rear to the front in the leveling direction, so that the front side of the blade, which is provided with multiple cutting claw portions, is prevented from floating up from the bottom of the water during leveling, allowing for stable leveling work.

[0018] Furthermore, according to the present invention, when the receiving surface of the main body is in a vertical position, the tip position of the cutting claw portion is lower than the lowest surface position of the compacting portion, so that the soil and sand can be firmly compacted from above.

[0019] Furthermore, according to the present invention, the wires extend from the left and right rear sides of the hull in the leveling direction corresponding to the pair of left and right arms, and the ends of the wires are split into two, one connected to the front upper part of the main body and the other connected to the rear upper part of the main body, which also prevents the front side of the blade from floating up from the bottom of the water when leveling.

[0020] The configuration of a leveling barge with such a blade is not something that has existed in the past, including Patent Document 1, and is therefore extremely unique. [Brief explanation of the drawings]

[0022] A leveling barge 100 according to an embodiment of the present invention will be described with reference to FIGS.

[0023] As shown in FIG. 1, the leveling barge 100 according to the embodiment of the present invention has a pair of left and right arms 20, 20 at both ends in the left-right direction, which is the width direction of the hull, and a blade 30 is attached between the pair of left and right arms 20, 20. One end 21, 21 of a pair of left and right arms 20, 20 is attached to the left and right of the hull so as to be able to rotate freely, and the other ends 22, 22 of the arms 20, 20 are located in the water, and a blade 30 for leveling the bottom of the water is attached between the arms 20, 20 on the other ends 22, 22. The tip of a wire 50 extending from the rear side of the hull in the leveling direction is fixed to the blade 30, and the height position of the blade 30 in the water can be adjusted by changing the length of the wire 50. The wires 50, 50 extend from a winch (not shown) installed in the center of the top surface of the hull (not particularly limited) corresponding to the pair of left and right arms 20, 20, and are attached to the blade 30 below via pulleys 40 installed on the left and right rear sides of the hull in the leveling direction. The leveling barge 100 normally moves forward by being pushed from the rear of the hull in the leveling direction to the front of the leveling direction (right side in Figure 1) by a push barge (not shown), but it is also possible to make the leveling barge self-propelled without a push barge.

[0024] As shown in FIGS. 2 to 4, the blade 30 includes a main body 31 serving as a base, a plurality of cutting claws 32, and a rolling portion 33.

[0025] The main body 31 is inclined upward from the rear side in the leveling direction to the front side in the leveling direction, and a receiving surface 31a is provided on the front surface which is the front side in the leveling direction. The other ends 22 of the pair of left and right arms 20, 20 are rotatably attached to the upper front portions of both left and right sides of the main body 31 in the leveling direction. The ends of the wires 50, 50 extending from the left and right sides of the rear side of the hull in the leveling direction are bifurcated, with one end 51 connected to the left-right center at the front upper part of the main body 31 and the other end 52 connected to the left-right center at the rear upper part of the main body 31. One end 51 of the wire 50 is connected rearward of the position of the receiving surface 31a provided on the main body 31, and the other ends 22 of the pair of left and right arms 20, 20 are connected forward of the position of the receiving surface 31a. The method of connecting the wire 50 to the blade 30 is not particularly limited and other methods may be used.

[0026] The cutting claws 32 are provided at intervals in the left-right direction at the lower end of the receiving surface 31a of the main body 31. The cutting claws 32 are provided so as to protrude from the lower end of the receiving surface 31a obliquely downward relative to the receiving surface 31a extending vertically, from the rear side in the leveling direction to the front side in the leveling direction.

[0027] The rolling unit 33 is provided at the rear lower part of the main body 31, has a curved surface 33a protruding downward, and rolls the soil and sand cut by the cutting claws 32. The rolling unit 33 extends continuously in the left-right direction (the width direction of the leveling barge 100), and its left-right width (length) is equal to the left-right width (length) of the blade 30 provided between the pair of left and right arms 20, 20. A space Q is provided between the cutting claw parts 32 and the rolling part 33, into which the earth and sand scraped by the cutting claw parts enters, and the earth and sand that has entered the space Q through the gap between the adjacent cutting claw parts 32 is compacted by the rolling part 33.

[0028] Furthermore, when the receiving surface portion 31a of the main body portion 31 is in a vertical position, i.e., in the state shown in Figure 2, the tip position P of the cutting claw portion 32 is lower than the lowest surface position S of the rolling portion 33. This allows the rolling section 33 to strongly compact the soil from above.

[0029] With the leveling barge configured in this manner, as shown in Figure 5, as the leveling barge 100 moves forward in the leveling direction, unevenness on the bottom surface of the water is scraped off by the cutting claw portion 32, and the scraped-off soil and sand are received by the receiving surface 31a, and as the leveling barge 100 moves further forward, the bottom surface of the water is leveled horizontally. The horizontally leveled bottom surface of the water is then compacted by the compacting section 33 having a curved surface 33a projecting downward, so that the bottom surface of the water is compacted and maintained in a neat, horizontal state for a long period of time.

[0030] Furthermore, since the main body 31 is inclined upward from the rear side to the front side in the leveling direction, the front side of the blade 30 provided with the multiple cutting claw parts 32 is prevented from floating up from the bottom of the water during leveling, and stable leveling work can be performed.

[0031] In this embodiment, as shown in Figure 4, the multiple cutting claw portions 32 are linear in the left-right direction from the left end to the right end of the blade 30 in a plan view (when viewed from above), and the rolling portion 33 is also arranged parallel to this from the left end to the right end of the blade 30. However, this is not limited to this. For example, as shown in Figure 6, the multiple cutting claw portions 32 may be linear in the left-right direction in the center of the blade 30 but bent or curved at both ends, or the rolling portion 33 may be arranged in the center of the blade 30 but not at both ends.
