Description

{Offshore access gangway}

The present invention relates to a damping type dipping apparatus, and more particularly, to a damping damping apparatus for supporting a maintenance structure for an offshore wind turbine such as an offshore wind turbine, which can minimize the shaking of the bridge The present invention relates to a damping type diving apparatus.

Recently, various structures are being constructed in the ocean. For example, large structures such as offshore plants or marine platforms such as FPSO, wind power or photovoltaic facilities are on the rise.

In particular, because wind power is renewable and does not cause greenhouse effect, it is attracting attention as an energy source to replace fossil fuels. And wind power generation is simple and easy to install, easy to operate and manage, and can be unmanned and automated.

In the past, wind turbines were mainly installed on the land, but due to environmental damage caused by noise and vibration, due to capacity enlargement, aesthetics and restrictions on places, wind power has recently been strong. It is a trend to build.

1 is a schematic view showing an offshore wind turbine generator.

The offshore wind power generator includes a wind power tower 1 fixed to the seabed and fixed to the underside of the wind power tower. The wind power generator 2 is rotatably coupled to the upper end of the wind tower to rotate by the wind, A generator for generating electricity from the power transmission device, and a docking facility (3) for allowing a ship loaded with manpower and equipment for repairing the wind power generator to be outside the wind power tower (1) .

As shown in the drawing, the docking station 3 includes four support pipes 3a installed on the outside of the wind tower, a pair of dock pipes 3b vertically installed apart from the support pipes, A connecting member 3c connecting the pipe and the eyepiece pipe, and a ladder provided on the side of the tower.

At this time, the two eyepiece pipes 3b and the support pipe 3a form a certain angle in the form of 'V'. Generally, the boat is tried to berth while the bow of the ship is drawn in between the two eyepieces.

However, in order to support the maintenance of the marine structures such as wind turbines, it is necessary for the support vessels to regularly berth.

The offshore support vessel is equipped with a gangway and a dynamic positioning system to compensate for changes in position due to swinging of the hull due to algae and wind direction, wind speed and wave height.

In this regard, various devices and equipments have been proposed, such as the following prior arts, which are used to navigate the offshore structure.

However, due to factors such as waves and winds during the docking, the support ship has three dimensional shaking.

More specifically, pitching, which is a rolling motion that rotates about the longitudinal axis passing through the center of the hull as a rotational motion, rolling, which is a rolling shaking around the transverse axis through the center of the hull, Yawing, which is a bow / stern swinging about the vertical axis through which the ball rotates.

As the linear motion, the hull is moved up and down along the longitudinal direction of the vertical axis, the swaying moves the hull to the left and right along the horizontal axis, and the forward and backward movement of the hull moves back and forth along the longitudinal axis occurs .

These fluctuations cause the yawing facility which is extended from the hull and which is seated on the structure to be shaken together, making it very difficult to stabilize the ship and also very dangerous when the operator crosses the bridge of the yawing facility. Particularly, in severe cases, the hull collided with the structure and the hull or structure was damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For a better understanding of the present invention, the description with reference to the drawings is not intended to limit the scope of the present invention. In the following description, a detailed description of related arts will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

FIG. 2 is a side view showing a damping type eyepiece apparatus according to an embodiment of the present invention, and FIG. 3 is a plan view of the present invention shown in FIG.

The present invention relates to an eyepiece facility for securing a ship by straddling a marine structure such as an offshore wind power generation facility and allowing a worker to safely access and perform work. More particularly, The present invention provides a damping type docking device having a structure capable of minimizing shaking caused by vibration.

Before explaining the present invention, a structure of an offshore wind power generation facility among the offshore structures attempting to breeze will be briefly described. A plurality of support pipes 10 are installed on the outside of a wind power tower, A pair of eyelet pipes 20 are vertically installed to be spaced apart from any one of the pipes 10 and the eyelet pipe 20 is connected to the connecting pipe 30.

At this time, the eyepiece pipe 20 is inserted into the eyepiece pipe 20 at an acute angle about the support pipe 10.

A plurality of the connecting members 30 connect and support the eyepiece pipe 20 and the supporting pipe 10 with a predetermined interval therebetween.

The present invention is installed on a bow of a ship as shown in the figure and may include a pedestal 100, a base bridge 200, a telescopic bridge 300, a clamping means 400 and a damping means 500 .

First, the pedestal is installed on the fore deck of the vessel s, and is shaped like a pillar. Accordingly, the pedestal 100 is vertically installed and fixed by bolting.

Since the pedestal 100 is equipped with the base bridge 200, the telescopic bridge 300, the clamping means 400 and the damping means 500, the pedestal 100 must be made of a material having rigidity and strength to withstand the weight , The deck should be fastened with sufficient fastening force.

Next, referring to FIGS. 4 and 5, the base bridge and the telescopic bridge will be described. FIG. 4 is a side view showing the detailed structure of the present invention shown in FIG. 2, and FIG. 5 is a plan view of the present invention shown in FIG.

The base bridge 200 is coupled to the pedestal 100 and the telescopic bridge 300 is installed to be inserted into the base bridge 200 so that the operator can actually go to the offshore wind power generation facility It is a composition that acts as a bridge.

The base bridge 200 and the telescopic bridge 300 are vertically formed with handrails 210 and 310 on both sides and have steps 220 and 320 at the bottom to form a passage shape like '┗.'.

At this time, the steps 220 and 320 may use a curved step as shown in the general form of '┏'. This is a form considering the slope because the slope of the bridge changes during actual docking.

However, when the elevation angle of the base bridge 200 and the telescopic bridge 300 is not large, that is, when the elevation angle is substantially horizontal, the elevation angle may be horizontal without a step on the floor.

Preferably, the base bridge and the surface of the bottom or step of the telescopic bridge are subjected to a non-slip treatment so as not to slip. For this purpose, the surface of the floor or stairs may have irregularities or non-slip pads.

A pair of wheels 230 and 330 are provided on both sides of both ends of the base bridge 200 and the rear end of the telescopic bridge 300 so that the telescopic bridge 300 is supported and supported in the base bridge 200, You can go back and forth to be able to go in while being guided.

Next, referring to Figures 6 and 7 together, the clamping means will be described. FIG. 6 is an enlarged view of an enlarged portion A showing a clamping means in FIG. 4, and FIG. 7 is an enlarged view of an enlarged portion B showing a clamping means in FIG.

The clamping means 400 is provided at the distal end of the telescopic bridge 300 to hook the hook 430 to one or both of the eyepiece pipes 20 when riding the telescopic bridge 300, Position.

To this end, the clamping means 400 may comprise a hook support 410, a hooking cylinder 420, a hook 430, a camera 440, a horizontal beam sensor 450, a vertical beam sensor 460 have.

The hook supporter 410 is a member that is coupled to both ends of the distal end of the telescopic bridge 300.

One end of the hook 430 is rotatably coupled to the hook support 410. At this time, the hook 430 is disposed to face the front and hooked while surrounding the outer periphery of the eyepiece pipe 20 while rotating, and the hooking is released while rotating.

The hooking cylinder 420 is installed for the operation of the hook 430.

The body of the hooking cylinder 420 is rotatably coupled to the end of the hook support 410 and the rod of the hooking cylinder 420 is rotatably coupled to one side of the hook 430. That is, the rod of the hooking cylinder 420 may be hinged to the back side of the hook 430.

Accordingly, as the rod of the hooking cylinder 420 moves back and forth, the hook 430 can be rotated to catch or release the eyepiece pipe 20.

For reference, the hooking cylinder 420 may be all operated or only one of them may be operated to hook the single eyepiece pipe 20.

Meanwhile, in order to check the position and the operation state of the hook 430 and the eyepiece pipe 20 in real time in the cabin c of the vessel during the hooking operation of the hook 430 to the eyepiece pipe 20, And a camera 440 for capturing and transmitting images.

The camera 440 may be a CCTV camera and may be installed on both sides of the front end of the telescopic bridge 300, specifically, on the rear side of the hook supports 410, respectively.

A horizontal beam sensor 450 may be attached to each of the hook supports 410.

The horizontal beam sensor 450 senses the position and distance in the horizontal direction (x, y direction) of the eyepiece pipe. The eyepiece pipe 20 is connected to the horizontal beam sensor 450 and the eyepiece pipe 20 reaches the set value, it can be determined that the hooking operation can be performed.

A vertical beam sensor 460 is attached to the hook 430. The vertical beam sensor 460 is a sensor for measuring the distance (height in the z direction) between the hook 430 and the connecting member.

The hooks 430 are hooked on the eyepiece pipe 20 and then put on one of the connecting members 30. For this purpose, the hook is adjusted to have a certain height above the connecting member 30 during the hooking operation, and then hooking is performed.

In addition, it is preferable that the inner diameter of the hook 430 is larger than the outer diameter of the eyepiece pipe 20. If the inner diameter of the hook 430 is the same as the outer diameter of the eyepiece pipe 20 and there is no clearance therebetween, abrasion may occur between the hook 430 and the eyepiece pipe 20 due to swinging, There is a problem of breakage.

In addition, a hook bracket 470 and a cushion spring 480 may be further inserted between the telescopic bridge 300 and the hook supporter 410. That is, the hook support 410 is not directly coupled to the telescopic bridge 300 but is coupled to the hook bracket 470 so that it can be disassembled or assembled. The hook bracket 470 is connected to the telescopic bridge 300, As shown in Fig.

The hook bracket 470 is formed in a flat plate shape and both ends of the hook bracket 470 are not fastened directly to the telescopic bridge 300 but fastened together with the cushion spring 480 inserted therebetween.

That is, it protects the equipment from damage due to overload caused by hull rolling and performs a cushion function.

Therefore, the clearance and cushion spring 480 can perform a function of attenuating or buffering a slight rolling (approximately 2 to 3 degrees) generated in the hull by compensating for it.

Next, the damping means will be described in detail with reference to FIGS. FIG. 8 is an enlarged view of the portion C showing the right and left rotary damping portions and the vertical damping portion in FIG. 4, and FIG. 9 is a DD sectional view showing a cross sectional structure of the front and rear damping portions in FIG.

The damping means 500 separately damps the left-right swing, the up-down swing, and the back-and-forth swing of the hull so that the swing of the bridge due to the shaking of the ship can be minimized during the docking operation so that the swing of the hull is transmitted to the bridge A left and right rotation damping unit 510, a vertical damping unit 520, and a front and rear damping unit 530. [

The left and right rotational dampers 510 are provided between the pedestal 100 and the base bridge 200 so that the base bridge 200 is rotated and rotated about the pedestal 100 within a range of right and left angles Or the transmission of the left-right rotation fluctuation of the hull can be attenuated.

The left and right rotational dampers 510 may include a swivel bearing 511, a swivel plate 512, a swivel driver 513, and a pivot pinion 514.

The swing bearing 511 is also called a slewing bearing and is divided into an outer ring 511a and an inner ring 511b and a ball or a roller is interposed between the outer ring 511a and the inner ring 511b So that they can rotate with each other.

At this time, gear teeth are formed on the outer periphery of the outer ring 511a, and the outer ring 511a is fixed to the upper portion of the pedestal 100.

A rotating plate 512 is coupled to the upper portion of the inner ring 511b and is rotatable.

The base bridge 200 is rotatably coupled to one side of the rotating plate 512.

A swivel driver 513 is provided on the other side of the swivel plate 512 to rotate together with the swivel plate 512. The swivel driver 513 may be a hydraulic motor.

A pivot pinion 514 is coupled to the axis of the swing driver 513 and driven to rotate. The turning pinion 514 is interlocked with the gear teeth of the outer ring 511a. Accordingly, the rotary plate 512 can be rotated forward or reverse within a predetermined angle range by the forward rotation or the reverse rotation of the turning pinion 514.

However, after the completion of the riding operation, the driving of the pivoting driver 513 is released to the free mode state. That is, in the free mode state in which the hydraulic pressure is not supplied, the rotary plate 512 is moved so as to freely turn without restraint, so that even when the hull is yawing to the left and right, it is transmitted to the base bridge 200 connected to the rotary plate 512 Or attenuated.

The vertical damping part 520 is provided between the rotary plate 512 of the left and right rotary dampers 510 and the base bridge 200 so that the base bridge 200 can be lifted up or down within a predetermined angle range, And the transmission of the upward and downward shaking motion of the hull can be damped.

To this end, the vertical damping unit 520 may include a hinge assembly 521, a support member 522, and a tilt control cylinder 523.

The hinge joint body 521 may be coupled to the side of the rotation plate 512 to be rotatable with the base bridge 200.

A support member 522 is vertically installed on the upper surface of the rotation plate 512. A pair is provided apart from each other.

The body of the inclination control cylinder 523 is horizontally rotatably coupled to the upper end of each support member 522. The rod of the tilt control cylinder 523 is rotatably coupled to the rear upper end of the base bridge 200.

Therefore, by driving the tilt control cylinder 523, the base bridge 200 can be heard or lowered by a required tilt angle.

However, after the riding operation is completed, the operation of the tilt control cylinder 523 is released to enter a free mode. That is, in the pre-mode state in which the hydraulic pressure is not supplied, the base bridge 200 moves so as to be freely lifted or lowered without restraint, so that even if the hull is pitching, Or attenuated.

The front and rear damping portions 530 may be provided between the base bridge 200 and the telescopic bridge 300 so that the telescopic bridge 300 is driven to move forward or backward in the base bridge 200, It is possible to attenuate the transmission of the fluctuation.

To this end, the front and rear damping portions 530 may be composed of a rack gear 531, a telescopic driver 532, a shaft 533, and a telescopic pinion 534.

The rack gears 531 are continuously installed on both lower surfaces of the telescopic bridge 300 along the longitudinal direction.

The telescopic driver 532 is horizontally installed at one end of the base bridge 200. The telescopic driver 532 may be a hydraulic motor.

A shaft 533 is coupled to the shaft of the telescopic driver 532 by a coupler. At this time, the shaft 533 is horizontally rotatably disposed across the base bridge 200 in a transverse direction.

Further, a telescopic pinion 534 is coupled to both ends of the shaft 533 to be rotationally driven. Here, the telescopic pinion 534 is interlocked with the rack gear 531. In other words, the rack gear 531 is placed on the telescopic pinion 534 so as to be interlocked with the rack gear 531.

Therefore, when the telescopic driver 532 drives the telescopic pinion 534, the telescopic bridge 300 provided with the rack gear 531 is driven forward and backward in the base bridge 200.

After the eyepiece is completed, the telescopic driver 532 is released from the free mode. That is, the telescopic bridge 300 can freely move forward or backward in a free mode in which no hydraulic pressure is supplied, so that even if the hull is swung back and forth, the telescopic bridge 300 is not transmitted to the telescopic bridge 300 connected to the base bridge Or attenuated.

The operation of the present invention will be described below with reference to FIGS. Fig. 10 is an operational state diagram showing the damping of the left and right rotational shaking in the present invention, Fig. 11 is an operational state diagram showing the damping of the up and down motions in the present invention, and Fig. 12 is an operational state diagram showing the front and rear swing damping in the present invention.

In the present invention, the respective components are operated and controlled as a whole in the cab (c) of the ship.

First, the ship is controlled so that the athlete is drawn into the eyepiece pipe 20, and the position is precisely adjusted while viewing the image transmitted from the camera 440.

At this time, the distal end of the telescopic bridge 300 is positioned on the upper side of the necessary connecting member 30 among the connecting members positioned at various heights, and the distal end of the telescopic bridge 300 is connected to the connecting member 30 at an appropriate height.

The hooking cylinder 420 may be operated by adjusting the eyepiece pipe to be positioned within the hook by judging from the measured value of the horizontal beam sensor 450 so that the hook 430 hooks the eyepiece pipe 20, .

Here, as soon as the clamping is completed, that is, when the hooking is completed, the supply of the hydraulic pressure is stopped to be controlled so as to be switched to the free mode state.

10, the outer ring 511a coupled to the pedestal 100 is rotatably coupled to the outer ring 511a even if the outer ring 511a rotates sideways, The rotation plate 512 coupled to the inner ring 511b is not largely rotationally pivoted since it is not transmitted to the ring 511b. Therefore, the base bridge 200 is hardly transmitted to the left and right rotation swing, so that attenuation is achieved.

11, the pedestal 100 and the rotating plate 512 are rotatably coupled to the rotating plate 512 even when the pedestal 100 and the rotating plate 512 swing up and down, Since the tip of the telescopic bridge 300 is fixed to the eyepiece pipe 20, the amplitude of the telescopic bridge 300 is greatly reduced toward the distal end of the base bridge 200 to be attenuated.

12, the pedestal 100 and the base bridge 200 swing forward and backward while the telescopic bridge 300 is fixed to the eyepiece pipe 20, The telescopic bridge 300 has little back and forth swing and is damped.

The left and right rotary dampers 510, the upper and lower dampers 520, and the front and rear dampers 530 are simultaneously operated simultaneously to form the three- Dimensional attenuation can be performed.

In the case of rolling, damping and buffering can be achieved to some extent due to the gap between the hook and the eyepiece pipe and the cushion spring without a separate damping structure.

If the rolling is severe, the base bridge may be driven to rotate at an angle of 90 [deg. That is, in such a state, rolling can be attenuated by the vertical damping portion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, as well as the appended claims.
