Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is intended to launch vessels such as work boats and patrol boats safely and reliably from a high place in dams, lakes, ponds, rivers, etc. The present invention relates to a mooring facility in a dam or the like that is pulled up from the water and stored, and a mooring method thereof.

[Prior Art] It is extremely difficult and difficult to launch a work boat or patrol boat from a high place on a lake shore of a dam to launch it or to pull it up from the water, but conventionally, a crane or winch was used. Then, a method of hoisting a ship with a chain block or the like and manipulating it manually has been common.

[Problems to be Solved by the Invention] However, such a conventional method is dangerous, and it is difficult to carry out the mooring work quickly and reliably and efficiently. When the water level changes drastically due to the increase or decrease of the water level, especially when the water level drastically decreases, there is a problem that the mooring work by manpower becomes more difficult and the risk becomes higher.

The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to lower a ship such as a work boat or a patrol boat from a high place at a lake shore of a dam or the like. All operations for launching or pulling up from the water can be performed safely, quickly and reliably and efficiently without using human-powered chain blocks, etc. It is an object of the present invention to provide a mooring facility and method in a dam or the like that can respond without any influence, and when the water surface is set to a preset water surface, the ship will be automatically stopped to launch the ship.

[Means for Solving the Problems] In order to achieve the above object, the mooring equipment such as a dam according to the present invention includes at least one or two units for laterally moving a ship on board at a pulling position above the water. A horizontal carriage, a horizontal rail for guiding the horizontal movement of the horizontal carriage, and a horizontal carriage that allows the horizontal carriage to freely transfer at the lifting position above the water. A possible installed incline carriage, a travel guide rail that guides the incline carriage along the slope, and a winding installed above the water so that the incline carriage is driven up and down by winding and lowering a wire rope. An upper device and a traverse driving device having a connecting portion so as to drive the traverse carriage with an endless chain driven by a motor to push and pull. Is.

Further, it is preferable that the above-mentioned incline carriage is equipped with a float under the vehicle body section so as to give a buoyant force when the incline trolley descends to the water surface and stop descending automatically by the buoyancy.

Further, as a mooring method for the dam or the like, a ship is mounted on a laterally movable traverse carriage, the whole carriage is pulled laterally to be mounted on an incline carriage, and the inkline carriage is hoisted by a hoisting device. There is a method in which buoyancy is applied by a float when it descends to the surface of the water to stop the descent, and at the same time, the vessel is launched from a traverse carriage in an Incline carriage.

[Operation] A case where two ships (a patrol boat and a work boat) are targeted will be described.

The patrol boats and work boats are individually loaded on the two horizontal trolleys No. 1 and No. 2 when they are at rest. And load it on the Incline carriage.

The incline carriage loaded with the traverse carriage is connected to the wire rope fed from the hoisting device, and the drum is driven by the electric motor to gradually lower the drum at the set slow speed.
Then, the Incline carriage descends on the slope along a slanted rail like a cable car, approaches the water surface, and then plunges into the water. A float is provided under the body of the Incline carriage, and since it floats in the water first, buoyancy occurs when it sinks to the surface of the water, and at the same time, the hoisting device stops when it detects it and the marine vessel progresses. Water is made.

The hoisting device is used to lift the lowered incline carriage. When the hoisting device pulls the incline carriage up to the rest position above the water, it automatically stops at a predetermined position.
In this stop position, the traverse carriage is automatically coupled to the connecting portion of the traverse drive device that is waiting in advance, and then the motor drives to drive the endless chain, and the previous traverse carriage is accompanied by the chain. It is returned to the original rest position again.

[Examples] Examples will be described with reference to the drawings.

The present embodiment shows a case in which two traverse carriages are moved laterally from each of the left and right sides with respect to one incline carriage so that two or more ships can be respectively lifted and lowered.
