Description

[Detailed description of the invention] TECHNICAL FIELD This invention relates to a ship docking device.

When repairing a ship, after docking the ship,
First, the hull surface is washed with high-pressure water to remove salt and deposits, then the treads are plastered, and finally, it is painted. After completing this series of hull surface treatment work, the ship is docked outside the dock. let

Such docking and docking operations and surface treatment operations are the main operations in docks, and equipment for performing these operations is indispensable as dock equipment.

Surface treatment work has conventionally been carried out using self-propelled surface treatment carts installed on both side walls of a dock.

In addition, conventionally, ships have been docked and undocking by towing the ship with wire ropes, but with such rope-towing devices, ropes cannot be attached to or removed from the ship during docking. Since this is done manually by many workers, there is a temporary peak in the work and there are safety issues.

Additionally, as the docks expand, the ships entering and exiting the docks also become larger, and the diameter of the ropes increases, further increasing the peak of this work.

For this reason, it is conceivable to install a self-propelled adult docking truck on the side wall of the dock and tow the ship with this truck to carry out docking and undocking work.

However, surface treatment work in a dock and dock entry/exit work are not both performed at the same time, and while one work is being done, the other work is not done.

Therefore, providing two types of self-propelled carts separately as described above is uneconomical, and when one cart is in use, the other cart may get in the way.

It is also possible to use a single truck for both surface treatment work and docking/undocking work, but in this case, it would be necessary to increase the weight of the truck to tow the ship during loading/unloading work, and surface treatment work would be required. When doing this, the entire heavy truck must be moved.

Generally, the frequency of running a bogie for surface treatment work is greater than the frequency of running a bogie for input/output work, and running the entire heavy bogie during surface treatment work increases operating costs. It is uneconomical.

SUMMARY OF THE INVENTION An object of the present invention is to provide an economical ship docking and docking device that solves the above-mentioned problems and can save labor and improve safety in docking and docking operations.

In the ship loading/unloading device according to the present invention, a surface treatment truck equipped with a hull surface treatment device and a loading/unloading truck equipped with a hull suction cup that can move forward and backward run along the side wall of a dock in a substantially horizontal force direction. These carts can be connected and disconnected, and only the surface-treated cart is provided with a traveling drive device.

When performing docking/docking work, the surface treatment cart and the docking/docking cart are connected, the ship is adsorbed by the hull suction cup of the docking/docking cart, and both carts are driven by the surface treatment cart's travel drive device. , towing ships.

Therefore, there is no need to use a wire rope for traction as in the past.

Further, when performing surface treatment work, the surface treatment truck and the docking truck are separated, the loading and unloading truck is stopped at an appropriate position such as the entrance or back of the dock, and only the surface treatment truck is allowed to travel.

As described above, according to the present invention, by connecting the surface treatment truck and the docking/docking truck, ship loading/undocking work can be performed without using a wire rope for towing, and the work can also be automated. It is possible.

Therefore, it is possible to save labor and improve safety in input/output operations without requiring as many workers as in the past.

In addition, when performing surface treatment work, the surface treatment truck and the input/output truck can be separated and only the surface treatment truck can be run, which reduces operating costs for the frequently used surface treatment truck, making it economical. .

Furthermore, since only the surface treatment truck is provided with a traveling drive device and the input/output truck is not provided with a traveling drive device, it is economical.

A guide rail 42 extending vertically is provided on the opposite side surface of the vehicle-side vertical part 26 of the input/outlet platform, and an elevating body 43 is installed between these guide rails 42 .
are attached via a plurality of vertical rollers (paths shown).

An electric winch 45 is installed on the top of the upper horizontal part 27 of the input/outlet truck, and the electric winch 45 raises and lowers the elevating body 43 along the guide rail 42 of the vertical part 26. It's lowered.

One end of a horizontal arm 47 is attached to the elevating body 43 so as to be rotatable about a vertical axis, and both ends of an arm rotation cylinder 48 are attached to the intermediate portion of the arm 47 and the elevating body 43. .

A hull suction cup 49 is attached to the rotating end of the arm 47, and this suction cup 49 can be tilted arbitrarily along the hull.

Moreover, a hydraulic unit 50 for driving the cylinder 48 and a vacuum pump unit 51 for driving the suction cup 49 are provided on the upper part of the elevating body 43.

Note that the input/outlet truck 5 is not provided with a traveling drive device.

The entry/exit device 3 on the back side of the dock also uses the same upper and lower rails 7 as above.
．． 8 is similarly attached.

The access/discharge device 3 on the back side of the dock is symmetrical to the access/discharge device 3 on the dock entrance side with respect to a vertical plane perpendicular to the dock side wall 2.

Moreover, the access/discharge device 3 of the dock side wall 2 on one side is symmetrical with the corresponding access/discharge device 3 of the side wall 2 on the opposite side with respect to the vertical plane of the dock 1 which is parallel to the side wall 2.

In the above, when loading and unloading work is not being performed, the two carts 4 and 5 of each loading and unloading device 3 are separated from each other, and each loading and unloading truck 5 is stopped at the entrance and back of the dock side walls 2. And waiting.

That is, the fixing block 31 of each input/outlet truck 5 is placed on the corresponding intermediate rail 29 for input/outlet truck standby,
By fitting the protrusions 30 of the rails 29 into the grooves 32 of the blocks 31, the input and output conduit truck 5 is fixed to the intermediate rail 29.

When carrying out the loading and unloading work, the two carts 4 and 5 of each loading and unloading device 3 are connected as shown in FIGS. 8 to 11 in the following manner.

That is, first, the surface treatment truck 4 is moved to a position where its vertical portion 12 approaches the corresponding input/output truck 5.

When the surface treatment truck vertical section 12 approaches the input/outlet truck 5,
The surface treatment truck horizontal section 11 moves along the outside of the input/output truck 5 without interfering with it, and eventually the connecting plate 17 of the surface treatment truck 4 enters between the connecting block 33 and the connecting plate 34 of the input/outlet truck 5. Therefore, the surface treatment truck 4 is stopped when the connecting holes 18,44 of these connecting plates 17,34 match.

After the connecting pin 38 is lowered by the connecting cylinder 36 and inserted into the connecting holes 18 and 44, the push-up cylinder 39 lowers the push-up pin 41 to lift the input/outlet truck 5.

The connecting pin 38 is connected to the connecting plates 17 and 34 of the two trolleys 4 and 5.
By inserting it into the hole 18° 44, the two carts 4,
5 are connected to each other, but with this alone, the fixing bracket 31 of the input/output truck 5 is still on the intermediate rail 29, so the input/outlet truck 5 cannot be moved.

Then, the fixing block 31 is separated upward from the intermediate rail 29 only by lifting the input/outlet truck 5 with the push-up pin 38, and as the surface treatment truck 4 travels, the input/outlet truck 5 also interferes with the intermediate rail 29. You will be able to drive without any problems.

The docking work of the ship 52 is performed in the following manner with the two carts 4 and 5 of each docking/undocking device 3 connected as described above.

That is, first, a tugboat (as shown) is used to guide the ship 52 to the vicinity of entering the dock, and the bow portion thereof is placed in the dock 1.

At this time, the four docking devices 3 on both side walls 2 of the dock are located near the entrance of the dock, and the elevating body 43 of the docking truck 5 is fixed to the upper part of the vertical part 26 by a stopper (path shown in the figure). The plate 49, ie, the arm 47, is rotated outward and retracted into the elevating body 43, as shown by the broken line in FIG.

Once the bow of the vessel 52 has entered the dock 1 to some extent,
The arms 47 of the two docking/undocking devices 3 on the back side of the dock are rotated inward to move the suction cups 49 to the ship 52 side, and the inclination of the suction cups 49 is adjusted appropriately to move the side shell plate on the bow side. is sucked by the suction cup 49.

Once the bow has been adsorbed in this way, the two docking devices 3, namely the surface treatment truck 4 and the docking truck 5, are moved to the back of the dock while adjusting the attitude of the vessel 52 using a tugboat. As a result, the ship 52 is pulled into the dock 1.

Once most of the ship 52 has entered the dock 1, the suction cups 49 of the two dock entry/exit devices 3 on the dock entrance side will suck the ship's side outer plate at the stern in the same manner as described above, and the four dock entry/exit devices 3 to the back of the dock, the ship 52 is further drawn into the dock 1 (see FIG. 1a).

Once the ship 52 has been pulled in to a predetermined position, the four docking/docking devices 3 are stopped, the ship 52 is braked and stopped by the tugboat connected to the stern, and the arms 47 of each device 3 are rotated as appropriate. By doing so, the vessel 52 is positioned in the width direction.

Then, the tugboat is separated from the ship 52 and the entrance gate of the dock 1 is closed.

A plurality of boards are placed at predetermined positions on the bottom 53 of the dock 1 before the ship 52 is brought in, and after the entrance gate is closed, the water in the dock 1 is drained at full speed.

As the water level in the dock 1 decreases, the ship 52 also gradually descends, but by removing the stopper that fixes the elevating body 43 to the vertical part 26 of the docking truck and by slipping the brake of the winch 45, the elevating body 43 is ship 52
, and the position of the ship 52 in the horizontal plane is maintained constant.

Then, when the vertical distance between the bottom of the ship and the center board reaches a certain value, the system switches to half-speed drainage, and when the bottom of the ship reaches the center board, the drainage is stopped and the position of the vessel 52 is inspected. .

If the ship 52 is not positioned correctly, water is poured into the dock 1 to slightly lift the ship 52 off the central board.
After adjusting the position of the ship 52, the same operation as above is performed.

If the ship 52 is positioned correctly, adjust the height of the boards on both sides to receive the ship 52 with all the boards, and
The suction cup 49 of the loading/unloading device 3 of the platform is separated from the vessel 52 and moved into and out of the elevating body 43, and the elevating body 43 is raised and fixed to the upper part of the vertical portion 26 of the loading/unloading cart.

Then, the water is drained again at full speed, and eventually all the water in the dock 1 is drained and the work is completed, and the ship 52 is supported on the board.

The above operations can be performed automatically by using various sensors and microcomputers that detect the horizontal position and vertical position of the ship 52, or can be performed semi-automatically by manual operation.

When the docking work of the ship 52 is completed, the two carts 4 and 5 of each docking device 3 are separated from each other in the following manner.

That is, first, the four docking devices 3 are moved to the entrance and the back of the dock side walls 2, and each is moved so that the fixing blocks 31 of the docking carts 5 are above both ends of the corresponding intermediate rails 29. The inlet/outlet device 3 is stopped.

Then, by raising the push-up pin 41 with the push-up cylinder 39, the input/outlet truck 5 is lowered.

As a result, the protrusion 30 of the intermediate rail 29 fits into the groove 32 of the fixing block 31, and the loading/unloading cart 5 is connected to the intermediate rail 2.
It is fixed at 9.

Next, the connecting pin 38 is raised by the connecting cylinder 36 and pulled out above the connecting plate 11 of the surface treatment truck 4, and the two trucks 4 and 5 are separated.

As a result, the surface treatment truck 4 is able to move freely away from the input/output truck 5, so the hull surface treatment work can be carried out in the same manner as before using only the surface treatment truck 4.
(See Figure 1).

When the ship 52 is to be docked after the hull surface treatment work is completed, the above-described docking work may be reversed.

In the embodiment described above, the docking and unloading carts 5 are provided on the side walls 2 on both sides of the dock 1, but the docking and unloading carts 5 may be provided only on one side wall 2.

Further, in the above embodiment, two docking and unloading trucks 5 are provided on one side wall 2 of the dock 1, but there is also a case where only one loading and unloading truck 5 is provided on one side wall 2.
