Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the improvement of a dredge boat equipped with a power shovel.

[Conventional technology]

A power shovel is mounted on the ship body so that it can rotate,
In a dredging vessel that performs dredging work using a power shovel, lubricating oil for the shovel attachment, fuel for the engine, cooling water, and the like are stored in tanks attached to the shovel.

[The problem that the idea aims to solve]

This type of equipment has the problem of being unable to perform long-term work on water due to limitations on lubricating oil, fuel, cooling water, and the like. For example, the grease on the bearings of a power shovel is washed away because the excavation is done underwater, so the grease must be injected in fairly short cycles, and when the work gets longer, it has to be frequently returned to the base.
Must receive grease reinforcement.

The object of the present invention is to improve the problems of the prior art as described above and to provide an improved dredge boat that can continue to work underwater.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the present invention installs tanks for storing lubricating oil, fuel, cooling water, etc., which have a larger capacity than the tanks in the power shovel, in the ship's body, and also connects each tank with the related information in the power shovel. The present invention is characterized in that it includes a means for supplying tank contents to equipment, and that the means for supplying tank contents is configured to be detachable between a connection stand installed in the ship body and a power shovel.

[Effect]

As mentioned above, the present invention installs tanks in the ship body that store lubricating oil, fuel, cooling water, etc. with a larger capacity than the tanks in the power shovel, and each tank stores tanks for the power shovel's related equipment. Since it is equipped with a means of supplying materials, when the contents of the tank on the power shovel become low, it can be refilled from the tank installed on the ship itself and continue work without having to return to the base. In particular, in the present invention, the means for supplying the tank contents is configured to be removable between the connection stand installed on the ship body and the power shovel, so that the connection stand and the power shovel can be connected only when replenishing, and the power shovel can be connected to the power shovel. During the work, the connection stand and the power shovel can be separated to facilitate work including turning the power shovel.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the accompanying drawings, reference numeral 11 indicates a ship body, and reference numeral 12 indicates a power shovel.

The ship body 11 has a known configuration. The power shovel 12 is installed near one end of the ship body 11, and a ballast is installed on the opposite side of the ship body to balance the ship.

The power shovel 12 has a configuration similar to that of a hydraulic excavator, which is a land-based device.The main body 13 is attached to a fixed base 14 installed on the ship main body 11 via a swivel device 15, and the front attachment 16 is attached to the main body 13. The bucket can be moved to any desired position by horizontal rotation of the main body and expansion and contraction of the boom, arm, and bucket cylinder that make up the front attachment.

In addition to tanks for grease for the front attachment, fuel for the engine, and cooling water that the power shovel is equipped with, the dredger according to the present invention also has a tank with a much larger capacity than the tank in the power shovel. It is installed in the ship body 11. In the drawing, of these, a tank 21 containing grease and a fuel tank 22 are shown.
Of course, a cooling water tank is also installed.

The ship body 11 is also provided with means for supplying the contents from these tanks to the tanks of the power shovel. This means includes a grease pump 23 for pumping grease and a fuel pump 24 for delivering fuel, and these inlets and outlets are connected to the tanks 21, 22 and the power shovel 12.
It is connected to a connection stand 25 installed on the ship's body in the vicinity of by suitable piping. Of course, the piping between each tank and the connection stand is independent.

The connection stand 25 has, for example, a female joint at the outlet of each pipe. Flexible hoses 27 and 28 are connected to these joints via male joints. Female joints 29, 30 are attached to the opposite ends of these hoses. The power shovel 12 is provided with a male joint that forms one joint with these female joints. In the figure, joint 29
31 is designated by reference numeral 31.

These male joints are connected to a tank in the power shovel via appropriate piping and valves.

The flexible hoses 27 and 28 are normally removed from the connection base 25. When supplying grease, connect the flexible hose 27 to the connection stand 2.
5 and the grease supply means of the power shovel 12 and operate the grease pump 23. In addition, the fuel is supplied with flexible hose 2.
8 is connected to the connection stand 25 and the fuel supply means of the power shovel 12, and the fuel pump 24 is operated.

The dredge boat according to the present invention has the following features:
Grease, fuel, etc. can be stored in the large-capacity tanks 21 and 22 installed in the ship's body, so by filling each tank with grease, fuel, etc., it is possible to carry out long-term or long-term Able to perform work on water. for example,
As mentioned above, grease is washed away by seawater, river water, etc., so it requires many times more daily inspections than on land, and must be injected after each inspection. Drilling vessels stock a large amount of grease and can supply as much grease as needed, allowing them to carry out heavy excavation work over long periods of time without failure. Furthermore, since the tank of the dredger itself has a considerable weight, the ballast for the power shovel 12 can be made smaller than that of the conventional type.

Further, by disconnecting the connection base 25 and the power shovel 12, the power shovel can be operated without any problems.

[Effect of idea]

As mentioned above, the dredge boat of the present invention has the following features:
Compared to traditional dredgers, it can carry much larger quantities of fuel, lubricants, cooling water, etc. for power shovels, allowing them to operate on the water for long periods of time without having to frequently return to base for reinforcements. It is possible to perform work using a power shovel, including turning, smoothly.
