Description

Apparatus for leveling and leveling the foundation sandstone for offshore construction {Mound Leveling Apparatus}

The present invention relates to an apparatus capable of automating the flattening operation of a mound built on the seabed for the construction of offshore structures such as breakwaters.

Offshore structures such as caisson and jamje are constructed on the foundation sandstone layer built on the seabed. The foundation sandstone layer built on the seabed is a structure that is flattened by selecting sandstone.

Conventionally, the work of constructing the foundation rock layer was carried out in a way that the rock was dropped on the seabed, and the diver directly picked the rock and flattened it. The depth of the water for selecting the foundation stone is about 20m. Since the time that divers can actually work is short at these depths due to divers, a large number of divers personnel are required to build a mound. In addition, since the diver selects rocks by hand, the speed of the work was also slow.

Civil engineering works on land can be handled by heavy equipment. However, there is a problem that these heavy equipment cannot be used in the submarine environment.

The present invention has been devised to solve the above-described problems, and an object of the present invention is to provide a mound planarization apparatus capable of performing the planarization operation of the foundation sandstone layer with equipment rather than manpower.

In order to solve the above problems, the present invention includes a body frame 10 extending long in the front-rear direction; a pair of rail members 19 provided on both lower sides of the body frame 10 and extending in the front-rear direction; a moving device 30 installed on the pair of rail members 19 so as to be movable in the front-rear direction along the rail member 19; a power generating device (35) for providing a driving force for the moving device (30) to move in the front-rear direction along the rail member (19); and a blade 40 installed in front of the moving device 30 and moving in the front-rear direction together with the moving device 30; provides a mound flattening device comprising.

The blade 40 moves forward together with the moving device 30 and flattens the sandstone dropped in front of the blade 40 .

The body frame 10 includes: a pair of upper extension members 11 provided on both upper sides of the body frame 10 and extending in the front-rear direction; a lower extension member 12 provided on both lower sides of the body frame 10 and extending in the front-rear direction; a plurality of upper cross members 14 spaced apart in the front and rear directions and extending in the width direction to connect the pair of upper extension members 11; A plurality of column members (17) spaced apart in the front-rear direction and extending in the vertical direction to connect the upper extension member (11) and the lower extension member (12); and a plurality of lower cross members 15 spaced apart from each other in the front and rear directions and extending in the width direction to connect the pair of lower extension members 12 to each other.

The body frame 10 is composed of only long beam-shaped skeletons, so that it is possible to minimize the phenomenon that the body frame 10 is pushed or lifted by the current in the seabed environment where the current occurs.

The rail member 19 may be installed on the lower cross member 15 .

The lower cross member 15 includes: a pair of rail support members 151 connected to the lower extension member 12 and supporting the rail member 19; and a connection member 153 disposed between the pair of rail support members 151 and detachably connected to the pair of rail support members 151 .

In the process of flattening the gravel, the lower cross member 15 is placed on the gravel to be flattened, and a portion thereof may be buried in the gravel. The pair of rail members 19 support the moving device 30 to which a significant load is applied and guide the movement of the moving device 30 , so it is preferable to be installed on the lower cross member 15 .

In addition, in consideration of the possibility of wear of the central part of the lower cross member 15, which is likely to cause friction with the gravel in the process of flattening the gravel using the mound flattening device, the connecting member of the lower cross member 15 ( 153) can be configured to be replaceable.

The connecting member 153 may include a hollow circular tube 154 and flanges 155 provided at both ends of the circular tube 154 .

The circular tube 154, in the process of lifting the lower cross member 15 buried in the gravel, prevents the flattened gravel from being disturbed again, and also minimizes the frictional force with the gravel.

Outriggers 60 may be installed at two or more locations among the plurality of pillar members 17 . In mounting the long body frame 10 on the sea floor in the front-rear direction, when the body frame 10 is mounted on the sea floor with a difference in height and curve, the position where the plurality of pillar members 17 are placed Even if there is a difference in the height of the seabed, if the function such as adjusting the length of the column member 17 downward using the outrigger 60 is exerted, the body frame 10 can be stably mounted. The length adjustment of the outrigger 60 may be performed by a hydraulic cylinder.

The outrigger 60 includes an outer cover 61 fixed to the pillar member 17 and extending in the vertical direction; an inner cover (62) inserted into the outer cover (61), extending in the vertical direction, and guided by the outer cover (61) to slide up and down; a post cylinder (631) whose upper end is connected to the outer cover (61) through a cylinder hinge (631h); a post piston 632 inserted into the post cylinder 631 and protruding downward from the post cylinder 631 by hydraulic pressure; and a lower support 64 exposed under the inner cover 62 and connected to the lower end of the post piston 632 through a piston hinge 632h.

The outer cover 61 and the inner cover 62 guide the expansion and contraction in the vertical direction, and can protect the post cylinder 631 and the post piston 632 operated by hydraulic pressure. In addition, the cylinder hinge (631h) and the piston hinge (632h) are made of sandstone and when the lower support 64 is supported on an uneven seabed, the lower support 64 can be guided so that it can be positioned in a stable position by itself. .

The moving device 30 may be moved by hydraulic pressure, and for this purpose, a hydraulic hose H may be connected to the moving device 30 .

To this end, the body frame 10 includes: a curtain rail 113 connected to the lower portion of the plurality of upper cross members 14 and extending in the front-rear direction; a plurality of rollers 114 inserted into the curtain rail 113 and moving along the longitudinal direction of the curtain rail 113; and a hose fixture 115 connected to the roller 114 and supporting the hydraulic hose H connected to the moving device 30 .

Meanwhile, a rack 191 may be installed on the rail member 19 along its longitudinal direction.

The rail member 19 may be a C-shaped steel whose open portion faces outward, and the rack 191 may be installed on the ceiling surface in the inner space of the C-shaped steel. Accordingly, it is possible to minimize the possibility that the rubble may roll into the inner space of the rail member 19 or the rack 191 portion in the course of picking up the rubble.

The moving device 30 includes: a cross beam 31 extending in the width direction to reach the pair of rail members 19; A front that is rotatably installed at both ends of the crossbeam 31 , and is rollably mounted on the rail member 19 so that the moving device 30 can move in the front and rear directions along the rail member 19 . a wheel 341 and a rear wheel 342; and a pinion 382 engaged with the rack 191 .

Since the moving device 30 is supported by the front wheel 341 and the rear wheel 342 spaced apart in the front-rear direction, it can maintain itself stable in the front-rear direction.

The power generator 35 provides a driving force for rotating the pinion 382 , and may be a hydraulic motor 35 operated by hydraulic pressure.

The moving device 30 includes: a first shaft 36 extending in the width direction to reach the pair of rail members 19 and rotatably installed in the moving device 30 ; a first driving sprocket 351 axially installed on the hydraulic motor 35 to rotate by the hydraulic motor 35; a first driven sprocket (361) axially installed on the first shaft (36) to rotate together with the first shaft (36); a first chain (352) connecting the first driving sprocket (351) and the second driving sprocket (362); a pair of second driving sprockets (362) axially installed at both ends of the first shaft (36) to rotate together with the first shaft (36); a pair of second shafts (38) arranged parallel to the first shaft (36) and rotatably installed at both ends of the moving device (30); a second driven sprocket 381 axially installed on the second shaft 38; and a second chain 363 connecting the second driving sprocket 362 and the second driven sprocket 381 to each other.

When the hydraulic motor 35 rotates, the first driving sprocket 351 rotates, and the rotational force is transmitted to the first driven sprocket 361 through the first chain 352 . Then, the second driving sprocket 362 at both ends of the first shaft 36 that rotates integrally with the first driven sprocket 361 also rotates integrally, and the rotational force of the second driven sprocket 363 is the second driven through the second chain 363 . It is transmitted to the sprocket (381).

The pinion 382 is installed on the second shaft 38 and rotates together with the second driven sprocket 381 . Since the pinion 382 is engaged with the rack 191 at the lower portion of the rack 191 , when the pinion 382 rotates, the moving device 30 moves forward or backward.

If the height of the blade 40 is adjusted in the process of selecting the height of the gravel, it is possible to efficiently select the gravel without straining the drive system. Accordingly, it may be more advantageous to adjust the height of the blade 40 with respect to the moving device 30 .

The body frame 10 may be in the form of a skeleton of a rectangular parallelepiped elongated in the front-rear direction. The body frame 10 includes a left skeleton and a right skeleton, and an upper connecting member connecting the upper portions of the left and right skeletons, and a lower connecting member connecting the lower portions.

The left skeleton and the right skeleton may have a symmetrical shape. The left skeleton and the right skeleton, respectively, are an upper extension member 11 provided on the upper portion and extending in the front-rear direction, a lower extension member 12 provided on the lower portion and extending in the front-rear direction, and the upper extension member 11 and the lower portion, respectively. It includes a plurality of column members 17 extending in the vertical direction to connect the extension member (12).

The upper extension member 11 and the lower extension member 12 may be arranged in parallel, and the plurality of pillar members 17 may be spaced apart from each other in the front-rear direction. The plurality of pillar members 17 may be disposed parallel to each other. The body frame 10 may further include a truss member 171 connecting the intersection of the column member 17 and the upper extension member 11 and the intersection of the column member 17 and the lower extension member 12 . .

The upper connecting member connecting the left skeleton and the right skeleton may be a plurality of upper cross members 14 that are spaced apart from each other in the front-rear direction and extend in the width direction to connect the pair of upper extension members 11 .

The upper cross member 14 and the lower cross member 15 may also be connected to the column member 17 .

Between the upper cross member 14 and the pillar member 17, a brace 141 for diagonally connecting them may be connected.

The body frame 10 is composed of only long beam-shaped skeletons in a range that can prevent deformation, so as to minimize the phenomenon that the body frame 10 is pushed or lifted by ocean currents in a seabed environment where ocean currents occur. can

The upper extension member 11 , the lower extension member 12 , the upper cross member 14 , the lower cross member 15 , and the column member 17 may be made of H-shaped steel, but are not necessarily limited thereto. .

The upper extension member 11 is provided with a ring member 111 for lifting the body frame 10 with a crane.

The rail members 19 extend in the front-rear direction, and are provided in pairs, one on the left and one on the right. The rail member 19 extending back and forth long may be installed on the plurality of lower cross members 15 .

The rail member 19 may be made of C-shaped steel. A horizontal portion provided at the lower portion of the C-beam may be fixed on the lower cross member 15 . A rack 191 may be installed on the bottom of the horizontal portion provided on the top of the C-beam. The teeth of the rack 191 may face downward.

The vertical portion of the C-beam may be disposed on the inside in the width direction. That is, the open portion of the C-beam may be disposed to face outward. In this way, it is possible to prevent the occurrence of burrs rolling into the inside of the C-beam.

A moving device 30 is placed on the rail member 19 , and the rail member 19 guides the forward and backward movement of the moving device 30 .

The pair of rail members 19 support the moving device 30 to which a significant load is applied and guide the movement of the moving device 30 , so it is preferable to be installed on the lower cross member 15 .

One of the lower cross members 15 includes a connecting member 153 and a rail support member 151 connected to both ends of the connecting member 153 , respectively. The rail member 19 is installed on the rail support member 151, and the rail support member 151 may be made of H-shaped steel to secure strength. On the other hand, the connecting member 153 is a member in which the tensile force and the compressive force in the longitudinal direction mainly act, while friction occurs with the sandstone, and may be in the form of a hollow circular tube. When the connecting member 153 is formed in a circular tube shape, it is possible to reduce friction with the sandstone. Since the connecting member 153 is placed in an environment where it is buried in a rock and lifted from it in the course of the work, it is necessary to replace it when the wear progresses. Accordingly, flanges 155 may be provided at both ends of the circular tube constituting the connection member 153 to be detachably fastened to the rail support member 151 by means such as bolts/nuts.

A curtain rail 113 extending in the front-rear direction is installed on the bottom surface of the upper cross member 14 . The curtain rail 113 is connected to the lower portion of the plurality of upper cross members 14 .

A plurality of rollers 114 are inserted into the curtain rail 113 . The roller 114 may roll in a longitudinal direction of the curtain rail 113 . And a hose fixture 115 for supporting the hydraulic hose H connected to the moving device 30 is connected to each of the rollers 114 .

The moving device 30 is installed on the pair of rail members 19 so as to be movable in the front-rear direction along the rail member 19 .

The moving device 30 includes a cross beam 31 extending in the width direction. The cross beam 31 may be an H-shaped steel. Two crossbeams 31 may be provided with a front and rear spaced apart from each other. The cross beam 31 may extend to an upper portion of the rail member 19 . Wheels may be provided at lower portions of both ends of the two crossbeams 31 . A front wheel 341 may be rotatably installed on the crossbeam 31 disposed in the front, and a rear wheel 342 may be rotatably installed on the crossbeam 31 disposed at the rear.

The front wheel 341 and the rear wheel 342 may be placed on the rail member 19 so as to be rolled in the front-rear direction. Specifically, the front wheel 341 and the rear wheel 342 may constitute a concave groove with a central portion having a diameter smaller than that of both ends in the width direction, and the member provided on the rail member 19 is located in the groove. can be accepted. Accordingly, the front wheel 341 and the rear wheel 342 can freely roll in the front-rear direction on the rail member 19 , but are structurally prevented from leaving the rail member 19 laterally.

The front wheel 341 and the rear wheel 342 are axially installed on a wheel housing 34 connecting the ends of the two cross beams 31 in the front-rear direction. The wheel housing 34 may be a “∩”-shaped steel extending in the front-rear direction and opened downward. The front and rear sides of the wheel housing 34 may be connected to two crossbeams 31 disposed at the front and rear, respectively.

Since the moving device 30 is supported at four points by the front wheel 341 and the rear wheel 342 spaced apart from each other in the front-rear direction at both ends, it is possible to maintain a stable posture.

A hydraulic motor 35 as a power generating device may be installed on the pair of cross beams 31 . The hydraulic motor 35 may be installed to be disposed in the middle of the width of the cross beam 31 .

A first driving sprocket 351 is installed on the rotating shaft of the hydraulic motor 35 . That is, when the hydraulic motor 35 generates rotational force, the first driving sprocket 351 rotates together with the rotation shaft.

A first shaft 36 is installed between the two crossbeams 31 disposed before and after. The first shaft 36 extends in the left-right direction, and the vicinity of both ends thereof is supported by a bearing 37 . The bearing 37 may be fixed to the upper surface of the wheel housing 34 exposed between the two crossbeams 31 .

A first driven sprocket 361 is axially installed in a portion of the first shaft 36 facing the first driving sprocket 351 . The first driven sprocket 361 is fixed to the first shaft 36 so as to rotate integrally with the first shaft 36 .

The first driving sprocket 351 and the first driven sprocket 361 are wound around the first chain 352 . Accordingly, the rotational force of the first driving sprocket 351 may be transmitted to the first driven sprocket 361 through the first chain 352 .

Second driving sprockets 362 may be axially installed at both ends of the first shaft 36 . The second driving sprocket 362 is fixed to the first shaft 36 so as to rotate integrally with the first shaft 36 . The second driving sprocket 362 is disposed adjacent to the bearing 37 , and disposed laterally outward from the bearing 37 .

The moving device 30 includes a housing 32 for accommodating and protecting the components for driving the moving device 30 therein. For example, the housing 32 may cover the pair of crossbeams 31 , the hydraulic motor 35 , the first shaft 36 , and the like.

At both ends of the housing 32, side plates 33 extending further downward than the cross beam 31 and not interfering with the rail support member 151 of the lower cross member 15 are provided. And a second shaft 38 is installed under the side plate 33 . The height at which the second shaft 38 is installed may be about a height corresponding to the inside of the C-shaped steel of the rail member 19 .

A second driven sprocket 381 is installed at a position corresponding to the position of the second driving sprocket 362 in the second shaft 38 . The second driven sprocket 381 is connected to the second driving sprocket 362 with a second chain 363 . Accordingly, the rotational force of the second driving sprocket 362 is transmitted to the second driven sprocket 381 .

A pinion 382 is installed on the second shaft 38 . The pinion 382 is accommodated in the rail member 19 and is engaged with the rack 191 .

The pinion 382 may rotate integrally with the second driven sprocket 381 . As an example, for this, the pinion 382 may be directly connected to the second driven sprocket 381 and fixed. In this embodiment, the pinion 382 and the second driven sprocket 381 may be rotatably rotatably installed with respect to the second shaft 38 or may be rotatably constrained with respect to the second shaft 38 .

As another example, the pinion 382 may be connected to the second driven sprocket 381 through the second shaft 38 . In this embodiment, since the second driven sprocket 381 must be delivered to the pinion 382 through the second shaft 38 , the pinion 382 and the second driven sprocket 381 are positioned relative to the second shaft 38 . It is pivoted so as to be rotationally constrained.

An upper portion of the rail member 19 is interposed between the front wheel 341 , the rear wheel 342 , and the pinion 382 . Accordingly, the moving device 30 is properly constrained to the rail member 19 , so that a phenomenon of separation from the rail member 19 can be prevented.

The side plate 33 of the housing 32 includes the first shaft 36 , the second shaft 38 , the second driving sprocket 362 , the second driven sprocket 381 , and the second chain 363 . It accommodates and protects the inside, and covers the inside of the rail member 19 so as not to be exposed to the outside.

Accordingly, when the hydraulic motor 35 rotates in one direction to advance the moving device 30 , the first driving sprocket 351 rotates in one direction, and the rotational force is applied to the first through the first chain 352 . It is transmitted to the driven sprocket (361). Then, the second driving sprocket 362 at both ends of the first shaft 36 that rotates integrally with the first driven sprocket 361 also rotates in one direction, and the rotational force is transmitted through the second chain 363. It is transmitted to the two driven sprocket 381, and the pinion 382 also rotates in one direction.

Similarly, when the hydraulic motor 35 rotates in the other direction to move the moving device 30 backward, as a result, the pinion 382 also rotates in the other direction so that the moving device 30 moves backward.

A blade 40 is disposed in front of the crossbeam 31 . The blade 40 has a “>” shape in which the central portion protrudes further forward. When the moving device 30 is flattened while pushing the rubble piled up in front of it, if a lot of rubble is piled up, it can act as a large load on the drive system. In such a working environment, flattening while pushing the upper part of the piled high stones first, and flattening while pushing the lower part further than that, the planarization operation can be divided into two or more steps.

To this end, the blade 40 may be installed in the moving device 30 so as to be able to move up and down with respect to the moving device 30 . Accordingly, a front elevation guide member 311 extending in the vertical direction is installed on the front surface of the cross beam 31 provided in front of the moving device 30 . A plurality of the front elevation guide members 311 may be provided, and the plurality of front elevation guide members 311 are spaced apart from each other in the width direction.

In addition, the blade 40 is provided with an upper support 42 and a lower support 43 extending rearward from the upper and lower portions, respectively. A plurality of the upper support 42 and the lower support 43 may also be spaced apart from each other in the width direction. A lifting member 41 extending in the vertical direction to connect the upper support 42 and the lower support 43 may be provided at rear ends of the upper support 42 and the lower support 43 . The lengths of the upper support 42 and the lower support 43 may also vary according to the degree of the front protrusion of the blade 40 . That is, the upper support 42 and the lower support 43 may extend further forward from the edge in the width direction toward the center.

The blade 40, the plurality of upper supports 42, the lower support 43, and the elevating member 41 may act integrally.

The vertical length of the elevating member 41 may be longer than the vertical length of the front elevating guide member 311 . The front elevation guide member 311 may have a substantially square square tube shape, and the elevation member 41 may have an H-beam shape having a smaller cross section than the front elevation guide member 311 as shown. However, their cross-sections are not limited thereto, and as long as the elevating member 41 has a shape that can be guided in the vertical direction by the inner circumferential surface of the front elevating guide member 311, it can be changed to various other cross-sectional shapes.

An elevation support member 312 is fixedly connected to the front of the front elevation guide member 311 . The lifting support member 312 is spaced apart from the lower portion of the upper support 42 . The lift driving unit 44 for elevating the blade 40 may be a hydraulic cylinder. The hydraulic cylinder may include a blade cylinder 45 and a blade piston 46 . The blade cylinder 45 may be hingedly connected to an upper portion of the elevating support member 312 , and the blade piston 46 may be hingedly connected to a lower portion of the upper support 42 .

Accordingly, when the hydraulic cylinder is extended, the blade 40 rises, and when the hydraulic cylinder is contracted, the blade 40 descends.

In order to apply hydraulic pressure to the lifting drive unit 44 and the power generating device 35 , a hydraulic hose H may be connected to the moving device 30 . Since the moving device 30 moves relatively back and forth with respect to the body frame 10, the hydraulic hose H is fixed to a plurality of hose fixtures 115 that can move along the curtain rail 113, As shown, it can move along the moving device 30 as if walking or hitting a curtain.

On the other hand, the body frame 10 is mounted on a mound formed on the bottom of the sea to perform the work of selecting a gravel. Since the body frame 10 is mounted on the mound before proceeding with the work of flattening the stone yet, the surface on which the body frame 10 is mounted has poor flatness. Therefore, the body frame 10 having a predetermined width and a length in the front-rear direction longer than that must first be placed horizontally on the mound.

Accordingly, the mound flattening device of the embodiment includes a plurality of outriggers 60 so that the body frame 10 can be horizontally mounted on the mound.

The body frame 10 is provided with a plurality of column members 17 spaced apart from the left and right in the front-rear direction.
