Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a carrier mooring device for a work boat for mooring a carrier vessel such as an earth carrier to a work boat that requires swing work such as a sand carrier or a dredger. .

(Prior art) In general, when sand is supplied from an earth carrier to a sand carrier, or when earth and sand dredged by a dredger is loaded onto an earth carrier, the sand carrier, dredger, etc. Since the earth carrier has a longer mud hold than the ship, it is necessary to gradually move the earth carrier in the fore and aft direction relative to the work vessel when loading or unloading earth and sand.

In such cases, conventionally, the work boat and the earth carrier were moored to each other by lashing mooring ropes to several bollards installed on each ship, and workers could attach the mooring ropes as needed. The method used was to untie the mooring rope, move the earth carrier using a shift winch, and secure the mooring rope again.

(Problems to be solved by the invention) In such conventional mooring methods, it is necessary to manually lash and unlash the mooring ropes each time the earth transport vessel moves, and Ships have longer mud bays than work boats, so they have to work more frequently, which requires a lot of effort and danger, and the time it takes to travel is longer, resulting in lower work efficiency.

In view of these conventional problems, the present invention aims to provide a mooring device that allows relative movement of a carrier vessel such as an earth carrier with respect to a work boat without requiring the mooring rope to be unlashed and re-secured. .

(Means for solving the problem) The gist of the present invention in order to solve the above-mentioned conventional problems and achieve the intended purpose is to provide a slide rail along the side of the carrier ship of the work boat. , a plurality of slide pieces are slidably supported on the slide rail, each of the slide pieces is provided with a mooring rope fixing device, and the work boat includes:
A carrier boat mooring device for a work boat is provided with a plurality of shift winches that pull the carrier boat moored to the work boat in a direction of relative movement back and forth.

(Function) This transport ship mooring device connects the mooring rope lashing device of the slide piece and the mooring part such as a bollard of the transport ship with a mooring rope, and in this state, the transport ship is moved in the longitudinal direction with a shift winch. When the slide piece is moved to , the slide piece is slid while maintaining the moored state.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, 1 is a work boat for removing sand from the seabed and dredging sand from the seabed, and 2 is a work boat that comes alongside this work boat 1 and supplies sand to the work boat during sand removal work. , is a transport vessel that loads dredged sand during dredging work.

This work boat 1 normally has Christmas anchors 3a, 3a... thrown in on three sides, and regulates its own position by adjusting the length of each anchor rope 4a, 4a..., swing anchors 3b, 3b, etc. It is made to swing by ropes 4b, 4b. A slide rail 5 is fixedly installed on the upper surface of the carrier ship berth of the work boat 1 along its longitudinal direction. As shown in FIG. 3, this slide rail 5 has a rectangular cross section and is fixed onto the deck 7 with a fixture 6. A plurality of slide pieces 8, 8 are slidably fitted on the outside of the slide rail 5 via a sliding member 9, and a mooring rope fixture 10 is integrally protruded from each slide piece 8. There is. As shown in FIG. 3, the mooring rope fixture 10 is formed into a ring shape by horizontally suspending a rope hanging rod 10b between the tips of a pair of support pieces 10a, 10a protruding from the slide piece 8.

In addition, a slide rail 5 is installed on the deck 7 of the work boat 1.
Shift winches 11a and 11b are provided on the back of the ship, and shift ropes 12a and 12b wound around both shift winches 11a and 11b are wound around pulleys 13a and 13b on deck 7 so as to be extended toward the transport ship 2 side. ing.

In addition, 14 in the figure is a fender. Furthermore, in the above embodiment, the slide piece 8 is provided outside the slide rail 5.
are fitted together to allow free sliding, but in addition to this, there is also a fourth
As shown in the figure, the slide rail 5 may have a C-shaped channel shape, and the slide piece 8 may be slidably inserted into the slide rail 5.

When using the mooring device configured as described above, the carrier ship 2 is brought alongside the work boat as shown in FIGS. 1 and 5, and the mooring rope fixing devices 10, 10 of the slide piece 8 are Inserted mooring rope 1
5 and 15 are fixed and moored to the bollards 16 and 16 of the carrier ship 2.

Similarly, shift ropes 12a and 12b
The tips of the bollards 17a and 17b are fixed to the bollards 17a and 17b on the bow and stern sides of the transport vessel 2, respectively. and,
When it is desired to change the mooring position of the carrier ship 2 relative to the work boat 1, the shift winches 11a and 11b are operated to pull one shift rope 12a or 12b and extend the other shift rope 12b or 12a. As a result, the slide piece 8 is moved along the slide rail 5, and the carrier is moved while maintaining the moored state.

(Effects of the invention) The carrier mooring device for a work boat of the present invention is configured as described above, in which a slide piece having a mooring rope fixing device is slidably supported on a guide rail provided at the side of the carrier boat of the work boat, The mooring rope between the work boat and the carrier boat can be untied by mooring the carrier boat to this slide piece and equipping it with a shift winch that can pull the carrier boat in its longitudinal direction. This allows both ships to be moved relative to each other without causing any problems, and the work can be carried out in a short period of time without stopping the operation of the work ship, which is advantageous for navigation and reduces work costs.Furthermore, it is highly safe for workers. It is something that has become familiar.
