Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a landing method K13W for lifting large offshore floating bodies such as ships and plant barges onto land.

For example, repairs to a ship's tank were carried out in a dock, or if there was no dock nearby, repairs could not be easily carried out. Furthermore, for example, when unloading plant equipment, it is necessary to use a quay or, if there is no quay nearby, to construct a new quay from the land side, which increases the cost of construction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for landing a floating body on the ocean that can be easily and reliably landed even without a dock or quay.

In order to achieve the above object, the method for landing the offshore floating body in Kibashi J is to install a suction table capable of adhering to the bottom surface of the offshore floating body on the upper part of the main body which has a propulsion device and can float freely, and the main body is equipped with a jet injection type position/direction Lubrication control device and a position/direction detection device, and furthermore, a plurality of I/Os are installed on the bottom side of the main body.
A plurality of landing gears configured with g-cut half wheels are prepared, and these landing gears are first moved a predetermined distance from land to the offshore floating body under the control of a controller on land.
Then, it is fixed at a specific position txt on the bottom of the offshore floating body 1f11 while controlling the position direction, and then moved while controlling the position direction and fixed at a predetermined position on the bottom.By repeating this, the landing device of the landing platform is fixed on the bottom. This is a method in which the offshore floating body is lifted onto land 1 by the thrust of the propulsion device and the drive of the four wheels.

According to this landing method, the landing gear is moved from land to a set point near the offshore floating structure! Then, the landing device is moved from the set point while controlling the position direction to face a specific position on the bottom surface of the offshore floating body, and then fixed at the specific position by suction by the suction device. Next, the landing device at the specific position 1a is moved without controlling the positional direction so as to face the fixed position 15i' on the bottom surface, and then fixed at the predetermined position by suction by the suction device. By this reversing, the reversing landing gear is sequentially moved from the specific position i1 to the larger predetermined position 11't, and is fixedly arranged on the bottom surface. Thereafter, each propulsion device can be operated to move the offshore floating body toward the land side. Then, by driving the wheels after they come into contact with the seabed due to the gradually shallowing water depth, the axle 14A can be used to drive the ocean 1 floating body towards the land, thereby making it possible to land it.

The action will be explained below. As shown in Figs. 6 and 9, a ship (6), which is an example of an offshore floating body, is anchored at 11α. Then, the i-reeler 0 end equipped with the control device is stopped on land, and the control device i' is set at the absolute position of the wheel 11.'t. Next, on the line (Z) connecting the control device axis and the ship's position, set the position near the ship's position as the setting point (6), and set the distance (Ll) from the absolute position to the setting point's position. ) to measure. The landing gear (1) is then moved at high speed within this distance (Ll). This movement of the landing gear (1) is effected by the propulsion force of the propulsion device (3), in which case the landing gear (1) is submerged or in the overflow IJu. Further, the direction during movement is detected and controlled by toy 0, and the distance is detected and controlled by time (speed detection). The setting voice point (B
) When the landing gear (1)r reaches the ballast tank (4) and suddenly becomes floating, it will be submerged by pouring water into the ballast tank (4). The level of this submergence will be below (at the bottom of the ship). The landing gear (1) located at the set point (5) in a submerged situation is activated by the position direction 11i1J control device (b).
■ ~ (The position direction is corrected by the jet stream from any one of 15. Here, the distance (L2) from the set point) to the specific position (Q) on the bottom of the ship is measured, and the distance (L8) is Based on this, the landing device (1) is moved at low speed and stopped below the specific position (C).Then, the entire unit is raised by the jet stream from the lower injection port (LLυ), and the adsorption device (8) is placed on the bottom of the ship. ), the landing device (1) can be fixed (temporarily fixed) at a specific position (Q) by applying an adsorption action while in contact with the landing device (1).
), the distance (L3) and direction (angle) from the specific position (C) to the desired position (Dl) (
θ) is given. The landing device (1) to which these control signals are applied is activated by the non-operation of the adsorption device (8) and the upper injection port α◆
The jet stream leaves the bottom of the ship and descends once, and the position direction is controlled until it reaches a predetermined position (DI
) at low speed and stopped below the predetermined position IPZ(Di). After this stop, the landing gear (1)
I finally made a posture correction, and the cylinder (5)
The ballast tank (4) is raised by increasing buoyancy due to gas supply from the ballast tank (4). The landing device (1) can be fixed (fixed) at a predetermined position (Dl) by contacting the suction device (8) (or the bottom of the ship) by e-lifting and causing an adsorption action.

By repeating such operations, multiple landing devices (1) are moved to specific positions as shown in FIG. Starting from (C), they are sequentially moved to predetermined positions (DI to Dlo) and fixed to the bottom of the ship <n, resulting in the state shown in FIG. After that, by operating each propulsion device (3), each ship is moved to land (
Move it towards c). Then, as the water depth gradually becomes shallower, the wheel (129) comes into contact with the seabed, and then, by driving the wheel (129 with hydraulic pressure), the ship (6) is directed toward land with the driving force of the wheel. It can be run and then landed as shown in FIG. After that, whether the boat 1'4 is driven to a predetermined location or not, the trailer is
Also runs. Before driving as described above, the trailer (
(b) Give instructions to the pressure setting device 1) from the control device N- on the side. Then, the pressure in the pressure setting device (Ove line) is detected (A), and based on that, the exhaust injection switching valve (To) is
output (to) to the exhaust injection switching valve) to switch to the injection invoice. As a result, the fluid in the cylinder (1) is injected into the pressurizing chamber (6 seconds), and the pressure in the pressurizing chamber (2) becomes the desired pressure. As a result, the boat was able to travel only once, and was once a hydraulic Tanabata (7)
The ship (6) can be self-propelled by driving and rotating each wheel (G). There are irregularities on the seabed and on the surface of the road, so when a depression is encountered while driving, the wheel (G) facing the depression is lowered by the fluid pressure in the pressurizing chamber (2) and comes into contact with the four parts.

At this time, whether the pressure in the expanded pressurized chamber Q is below the desired pressure,
This is done by switching the exhaust injection switching valve to the injection state based on the output based on detection (a), and the fluid in the cylinder is injected into the pressurizing chamber (2). The pressure inside the chamber Q is adjusted to a desired pressure. When the wheel (G) attached to the cylinder device with the desired pressure in the fourth part moves to the normal running surface, or when the wheel (G) on the normal running surface moves to a convex part, the wheel (G) (into the corresponding pressurized chamber) is compressed and raised above the desired pressure. Detection at this time (a)
The output (0) based on this causes the exhaust switching valve (Q) to switch to a poor exhaust condition, and the fluid in the pressurized chamber (Q) is released to the atmosphere, and the pressure inside the pressurized chamber (Q) is adjusted to the desired pressure. . When the ship ω4 comes to a curved path, the rotary drive device (2) is activated and the cylinder device f:'? Rotate ) around ) around the vertical axis,
Therefore, the direction of the wheel 14+ (181) is changed.The direction is changed from the front side of the vehicle, and in the left and right direction, the angle on the side of the turn is larger. The array position (distance) of θ~ is the control device (goods)
It is preset to .

When the load at each location on the plane of the ship (6) is constant and approximately constant, the desired set pressure of each pressurizing chamber 64 may be constant.However, in the case of an uneven load, the pressurizing chamber (
The desired set pressure for 2) will be varied pointwise or linearly.

According to the method for landing and landing of an offshore floating body according to the present invention described above, the following effects can be expected. 1--move the landing gear from land to a set point, i.e. near the offshore floating structure;
Then, by controlling the positional direction from the set point and moving the landing device to cause it to stick to the sea, the landing device can be fixed at the specific position. Next, the landing gear at a specific position is moved without controlling its positional direction so that it faces a predetermined position on the bottom surface, and then the suction device is applied to adsorb it, so that the landing gear can be fixed at the predetermined position. . By repeating this process, the plurality of landing devices can be sequentially moved from a specific position to a large number of predetermined positions, and can be fixedly arranged on the bottom surface of the Ocean E floating body. after that,
By operating each propulsion device, the offshore floating body can be moved toward the bottom. Then, by driving the wheels after the wheels come into contact with the seabed due to the gradually shallowing water depth, the floating body can be driven toward land using the vehicle's driving force, and then landed. This makes it possible to easily and easily land a floating object on the ocean even without a dock or quay.
