Description

High speed dredger for marine use

The present invention relates to a high speed dredger for marine use, more specifically, it is possible to smoothly transmit power using a long track to improve mobility in water and on land, and to adjust the length of the top and bottom of the spud by a hydraulic cylinder. The present invention relates to a newly improved high speed dredger for marine, which can be dredged more stably even at deep depths.

In general, sludge is deposited on the bottom of the surface of rivers or lakes by various wastewaters flowing from the land during rainy weather, or sludge is accumulated by artificial throwing. These sludges accelerate water pollution and destroy one's ecological environment. It is the cause. Therefore, a dredger is used to remove and dredge sludge accumulated on the bottom surface of a river or a lake.

The dredger is dredged to deepen the depth of rivers, canals, ports, and routes by mounting appropriate facilities and equipment according to the depth of the dredged water, the type of soil at the bottom, and the transport distance of dredged materials. It is used to collect soil, sand and minerals, including sludge under water, to build foundations for underwater structures, and to lift and remove sea waste.

However, when dredging the contaminated sediments deposited on the bottom of a river or reservoir using conventional dredging, there is a problem that the dredger floats out of the dredging work position due to the flowing water flow, and shakes from side to side during dredging work. There is a difficulty in dredging work, and there is a problem that a risk of safety accident occurs as the dredger is tilted.

As a related art to solve this problem, the present applicant can move on land and water using tracks such as caterpillar tracks, and an eco-friendly dredger which can fix a dredger at a dredging position without using a spud (10th) -2009-0052243) has already been filed.

However, due to the weak structure of power transmission to dredger tracks, it takes longer for the dredger to move from land to surface, and in particular for the small driving power delivered to the track, it is time to move from one point on land or water to another. This takes a long time.

In addition, the conventional dredger is a support means for fixing the dredger at the dredging position, provided a collapsible spud is provided at the rear end of the dredger, so when the dredger is fixed, the spud is vertically supported and supported on the underwater bottom, When the dredger was moved, the spud was refolded horizontally and settled along the longitudinal direction of the dredger, but since the length of the dredger was provided with a constant length, it was difficult to dredge because the support function of the stud was impossible at a deep depth.

In other words, the depth of the stud is shorter than the depth at the deep depth so that the spud does not touch the bottom of the water, there was a problem that can not be fixed in the dredging position dredger.

On the other hand, if the length of the spud is increased to a deep depth, the horizontal length becomes longer than the length of the dredger's hull when the spud is settled, which acts as an unstable element to the hull when the dredger is moved. There is a limit to increasing.

As shown in FIG. 1, the marine high speed dredger according to the present invention includes a buoyancy boat 100 and a fork lane 110 configured as a dredger based on a cutting means 200 based on a dredger blade. And, it is configured to include an air generating means 210, water jet generating means 220, vacuum suction unit 230, the depth gauge 240.

The high speed dredger for marine according to the present invention includes a buoyancy boat 110 having a predetermined area and internal volume, a propulsion engine mounted to generate a propulsion force of the buoyancy boat at a predetermined position inside the buoyancy boat, and the propulsion engine. A screw that is connected to provide a propulsion force to the buoyancy vessel and is rotated, a cab mounted at a front position on the upper surface of the buoyancy vessel, and a boom 101 connected to the front of the cab and operated hydraulically like a conventional excavator. do.

The boom 101 of the dredger of the present invention is configured as a three-stage collapsible articulated boom for dredging over a long distance, the support frame is mounted on the front end of the boom.

In addition, the support frame is provided with a blade 102 is integrally attached to the suction plate having a suction hole for sucking the dredged soil, a hose for supplying water to the blade cleaning means described later is fixed, in particular a hole for sucking dredged soil The net 104 for filtering large stones and the like is integrally attached.

A suction plate 105 having a suction hole for sucking the dredged soil is integrally attached to the rear of the blade 102, and the dredged soil extending to the rear predetermined position via the front of the buoyancy boat 100 is attached to the rear of the suction plate. A suction pipe is connected, and a dredged soil suction pipe is equipped with a centrifugal pump that provides suction power, and the dredged soil suction pipe serves to suck and move the dredged sludge and earth and sand sucked by the pumping force of the centrifugal pump to a desired position. .

In addition, the dredger of the present invention includes a buoyancy body (unsigned) that can balance the left and right balance of the buoyancy boat when the buoyancy boat is moved to the water, and at the same time absorb the shaking during the dredging work so that a stable dredging work can be performed, The buoyancy body is mounted on both sides of the buoyancy boat 100 so that it can be folded and unfolded, and it is in contact with the surface of the water while buoyant by buoyancy to balance the left and right balance of the buoyancy boat.

In particular, the dredger of the present invention is a means for fixing the buoyancy vessels do not move during the dredging operation, a total of four spud assemblies 120 are respectively installed in the front both sides and the rear both positions of the buoyancy vessel (100).

More specifically, the hollow guide tube for guiding the support bar 121 in the vertical direction of the configuration of the spud assembly 120 is fixed to the front both sides and the rear both sides of the buoyancy vessel 100, this hollow The support bar 121 is vertically erected in the guide tube and is inserted therethrough so as to be movable upward and downward, and a hydraulic cylinder having a piston is assembled to the outer surface of the medium light guide tube.

At this time, the front end of the piston is integrally assembled to the upper end of the support bar 121. As the hydraulic cylinder is driven, the piston moves forward or backward, so that the support bar coupled with the piston moves vertically upward or vertically downward.

That is, at low depths, the upward movement of the piston is operated to the maximum distance, and the support bar is moved upward in the upward direction, while the lower end of the support is supported on the bottom of the lower depth, and at deep depths, the upward movement distance of the piston is Minimal operation ensures that the bottom of the support bar is easily supported by the deep bottom of the water. By press-fitting and fixing the lower end of each support bar to the bottom surface of the water in the desired dredging position, it is possible to smoothly dredging work by preventing the buoyancy boat to move during dredging work.

In addition, the caterpillar assembly 130, which is a kind of caterpillar assembly, is mounted on both sides of the lower end of the buoyancy vessel 100, respectively.

As a means for providing a rotational driving force to the caterpillar assembly, the first and second sprockets are arranged at the front and rear ends on both sides of the lower end of the buoyancy vessel 100 and a plurality of driving wheels arranged between the first and second sprockets And a caterpillar which is covered with the first and second sprockets and the outer circumferential surface of the traveling wheel as being driven under rotational power by the first and second sprockets.

Therefore, when the power means connected to the traveling wheel of the caterpillar assembly 130 is driven, the caterpillar assembly 130 is also rotated. On the ground, each auxiliary wing formed on the outer surface of the caterpillar assembly 130 is grounded. Since the driving of the entire dredger serves as a contact plate for, it can be easily moved to the water without using a separate crane when moving from the land to the water as in the prior art.

In particular, when the dredger of the present invention is present in the water phase and wants to move from one point to another, if the distance is short, the water bass action of the auxiliary blade formed on the surface of the caterpillar assembly 130 or the caterpillar assembly 130 The water bass movement of the auxiliary blades formed on the side can be easily moved.

That is, since the separation distance between the distal end of each auxiliary blade is formed wide along the rotational direction of the caterpillar (the direction of dividing water), and the separation distance between the rear end of each auxiliary blade is narrow, a large amount of the distal end of each auxiliary blade Water is received and the water is separated and at the same time water is pushed through the narrow space between the rear end of each auxiliary wing is discharged, it can be made easy to move the dredger in the water.

Alternatively, the water bass operation of the auxiliary blade formed on the side of the caterpillar assembly 130 is made at the same time, so that the dredger can be easily moved in the water phase.

 Thus, when the dredger of the present invention moves a short distance from one point of the water phase to another point, it can be easily moved only by the water bass action of the auxiliary wing formed on the surface of the caterpillar assembly 130 or the auxiliary wing formed on the side thereof. Of course, when moving a long distance is moved by the driving force of the screw receives the power of the propulsion engine.

On the other hand, at the front and rear predetermined position of the buoyancy vessel 100, the mudguard plate to keep the water bass direction of the auxiliary wings formed in the caterpillar at the same time and to prevent foreign matter from penetrating into the blade side is integrally assembled.

Looking at the configuration of the cutting means 102, a rotating shaft mounted to the support frame in the horizontal axis, a plurality of rotating plates assembled at equal intervals along the rotating axis, and at equal intervals along the circumferential direction on both surfaces of each rotating plate It consists of a plurality of blades 102 to be mounted.

At this time, the end of the blade 102 is provided in a curved shape bent at a predetermined angle in order to increase the contact area to the dredging object.

In particular, the blades mounted on the one side rotating plate of the plurality of rotating plates are adopted with the longest radial length, and the blades 46 mounted on the opposite rotating plates are adopted with their radial lengths sequentially shortened.

That is, in view of the size (length) of the entire blades 102, it is adopted to have a length that gradually decreases from one side to the other, because the longest blade 102 when crushing the solid ground or lumped sludge When the first blade is crushed first and the shorter blades are crushed second and third continuously, the grinding efficiency can be increased.When the entire blade touches a solid dredging object at the same time, the blades are damaged or twisted due to the grinding impact. This is to prevent the occurrence.

On the other hand, the cutting means driving means is a gear box installed on the side of the support frame, the hydraulic motor 52 is fixed to the front end side of the boom, the output shaft of the gear box associated with the hydraulic motor and the rotating shaft of the cutting means Can be configured directly.

Therefore, when the rotational force of the hydraulic motor is transmitted to the rotating shaft through the gearbox, the blades mounted on the rotating shaft are to ground the sludge of solid ground or lump form, as described above, the longest blade is a solid ground or lump sludge The first grinding is performed, and gradually shorter blades are continuously grinding second and third.

As shown in FIG. 6, the dredger of the present invention is dredged by the blade 102, and dredged soil and crushed sludge, which are dredged, are sucked through the suction plate and at the same time, a large volume in the net. Is first filtered and sucked into the dredged soil suction pipe, and then is discharged through the discharge pipe protruding to one side of the buoyancy vessel, wherein the discharge hose (not shown) for transporting the dredged soil and sludge to the desired land treatment site In the end, dredged soil and sludge are easily transported to the land treatment site through the discharge pipe and the transport hose.

In another one of the main configurations of the present invention, the blade cleaning means for performing the next dredging work immediately by proceeding the water washing work for the blade using the vortex nozzle after the dredging work is the upper end of the support frame That is, it is mounted above the cutting means.

The blade cleaning means is composed of a plurality of vortex jet nozzles mounted at positions facing each blade, and a water pump connected to the vortex jet nozzle by a hose to supply water.

In particular, the vortex jetting nozzle is a means for rotating the sprayed water while increasing the water jetting force, the upper end is formed with a fastening portion having a screw thread to be engaged with the hose, the hollow conical body downward from the fastening portion Is formed integrally extending, the conical body is formed through a plurality of injection holes which are holes for the final injection of water along the spiral direction.

Cutting means 100 according to another embodiment of the present invention is divided into a body portion 102 and a blade 104, the body portion 102 is a cylindrical shape and the front end is formed in a convex ellipse shape and at the same time forms a mesh shape. It is provided with a lattice structure.

In addition, the body portion of the cutting means 200 as a pointed shape extending in all directions, a plurality of blades are integrally formed.

The cutting means 100 of another embodiment provided as described above is rotatably mounted via a bearing (not shown) to a mounting frame mounted at the end of the three-fold collapsible articulated boom 101.

That is, the rear end of the body portion of the cutting means 200 is rotatably mounted to the front of the mounting frame, a motor (not shown) for rotating the body portion is built in the mounting frame, the dredged soil suction pipe at the rear of the mounting frame Are joined.

Therefore, when the body portion of the cutting means 200 is rotated by the driving of the motor, the blade is ground to a solid ground or agglomerate sludge, and subsequently dredged soil and crushed sludge through a dredged soil suction pipe connected to the mounting frame It is sucked in, and since the body part is lattice-shaped, a large volume of dredging rock and the like are filtered out.

On the other hand, the high speed dredger according to the present invention is configured to further include a depth gauge 240 that can automatically measure the depth of the working depth. Depth meter is located in the suction plate to perform dredging work, if the depth value that satisfies the set value (depth value) set in advance by the operator comes out to provide an alarm sound to the alarm generating means located in the worker space To ensure that the work of the depth that satisfies is performed. This has the advantage that the operator can perform the correct work early depending on the setpoint dredging depth.

In addition, the depth meter configured in the suction plate is installed in a sufficiently covered state through a separate cover body in order to solve problems such as contamination or damage in the dredging operation there is an advantage that can ensure the mechanical stability.
