The Moyairan 7 is attached to the tip of the boat B, directly hooked to the movement guide device 2, and when reversed, it is pivoted to the wire drum 15 of the Moyaya winch 14, and as in the previous example, it can be automatically tracked while being constantly tensioned. Configure the Moyai net device.

(Operation of the Invention) The present invention will be described in detail according to the positions I, n, I, and IV of the boat shown in FIG.

(2) Storage position When the boat is stored, one end of the bowline net 7 is attached to the tip of the boat, and the other end is wound around the wire drum 15 of the bowline winch 14. Moyai net 7 is on the ship's deck. , the upper moving guide device 2 is red and white, and the necessary pulleys and the like are stretched to the twine winch 14 along the length 1.

In order to lower the boat suspended from the boat davit, when the operating lobe is pulled from inside the boat to lift the winch lever L of the boat winch W, the brake lever 15 of the moya net winch 14 linked to this is also lifted, and the band brake 28 is lifted. ] 3 f When the suspended cradle C is swung out to the side and boat B begins to descend, tension is applied to the moyai line 7 fixed to boat B, and the moyai line 7 is released from the moya net winch 14. The delivery begins.

However, since the restoring force of the mainspring spring 26 housed in the spring case 20 of the mower net winch 14 is adjusted in advance by an adjustment mechanism so that the spring rope 7 is reeled in when the tension is zero, the faster winch 7 is stronger than the restoring force of the spring. When it starts to freeze, it will start to move when the tension is large, but when it is small, it will roll in. It is a mechanism that always applies a constant tension to each piece 7 and prevents it from sagging on the deck etc.

■. The swinging position cradle Q (bow when it contacts the swinging cradle stopper 41 to the full four corners) descends to the acidic swinging position, and in the case of the first embodiment, in conjunction with the swinging angle of cradle 0, the cradle Q immediately below the cradle a. Deck D
The hydraulic pressure of the hydraulic circuit generated by the action of the throat 4 on the drive of the operating cylinder 3 protruding from above is introduced into the moving cylinder 5 of the moving guide device 2 installed on the deck D of the ship. The slide roller 6 attached to the tip of the drive head 30 is made to protrude in an acidic manner, and the bowline rope 7 guided by it is made to protrude in an acidic manner. This prevents the vehicle from descending in an unfavorable towing position. The movement time of the movement guide device 2 is adjusted by a throttle valve 37 in the hydraulic circuit.

Furthermore, when the brake lever L of the boat winch W is returned to its original position, the brake lever of the bowline winch 14 is also returned to its original position, so the band brake 28 is activated and the descent of the boat winch W is stopped, and the bowline 7 is also stopped. The edge of the rim is also stopped to hold the load.

In the case of the second embodiment in which the pulley frame 39 is provided with a rocking type movement guide device 2, a spring case 45 containing a return spring 44 is installed by a link device interlocking with a pin provided on a cradle stopper 41 when the cradle C is swung out. This embodiment is the same as the first embodiment except that the attached pulley frame 39 is swung in an acidic state to extend the boiling rope 7 in an acidic state.

■, When the boat is stored in the lowered position) As it descends, the bowline rope 7 attached to the tip of the boat B, which has been lowered by the hanger u41' suspended from D, is detached from the moving guide device 2 projected from above on the deck D0. The ship will continue to descend in the %6'C attitude, which is anchored to the deck end rollers 9 installed on board. In the case of the second practical example, the deck end roller 9 is omitted, so the installation position of the moving guide device 2 on the deck is well towards the bow so as not to cause strain on the towing attitude. When the lowered boat lands on the water, the boat winch lever L is put into the braking state by operating the rope inside the boat, so the brake lever 16 of the Rz winch works in conjunction with this.
Stops the feeding of the moyashi line 7 and moves it to the boat.
Even if the tension moves by 1, the load can be maintained, preventing the rope from being pulled diagonally by the main line 7, allowing safe towing.
It is towed by the t-1m removable net 7, and it becomes easy to proceed to the stage of starting the engine, starting, and leaving. 4 (Effects of the Invention) This invention has the following advantages since it is based on the above-mentioned purchase.

(1) Is it safe because in the event of an emergency using a boat, it is possible to fix Moyai 1 to the side of the boat, or to automate the dangerous work of supporting the Moyai net so that the boat does not drift away when landing on water? Be able to measure 7 fl.

(2) Since the movable guide device does not guide the mist/bow i1 by extending it acidically, the boat can be lowered safely without causing any damage to the towing position of the boat during the swing-out and descent of the boat.

(3) Since the winch can be operated in conjunction with the boat winch, it can be operated from inside the boat to follow the start of A'+'l, which is similar to A'+'l, and the constant tension can move the slack of the paulownia onto the deck. The boat can be held securely when landing on the water, and the boat can be safely evacuated in an emergency.
