Yawl withdrawing method and withdrawing and releasing device

Abstract

The invention discloses a yawl withdrawing method. The withdrawing method comprises the following steps that (1) a supporting device and a traction device are arranged on a hull of a mother ship, the supporting device comprises a bracket and at least two guide rails, and the traction device comprises a support and a winch; (2) the yawl sails from the water surface to the position in front of the at least two guide rails, the winch leads one rope out, and the rope is connected with the front end of the yawl; (3) a long rod is used to control the tail of the yawl to enable the yawl to be positioned in the bracket direction, and by rotating the winch and tightening the rope, the yawl is placed on the bracket through the at least two guide rails; and (4) the winch is locked, a blocking rod is inserted at the rear end of the bracket, and the yawl is fastened through another rope. A yawl withdrawing and releasing device comprises the supporting device and the traction device. The withdrawing and releasing device is simple and reasonable in structure, and an original deck space is not occupied; the withdrawing method has the characteristics that deck moving is not influenced, and safe operation performance is high; and the yawl withdrawing method and the yawl withdrawing and releasing device are especially suitable for ships with narrow decks, low ship rails and small tonnage.

Description

technical field [0001] Embodiments of the present invention relate to a recovery method and a retracting device for a ship-borne dinghy. Background technique [0002] According to the Maritime Safety Regulations on Ships, small boats must be carried on board, and small boats on board are necessary lifesaving and travel equipment. The existing ship-borne small boat retractable devices mainly include the lifting type and the stern slide type. Many small tonnage ships, especially some inland waterway ships, such as sightseeing boats, fishery and sea surveillance executive ships, and small construction operations Ships, the decks of these ships are narrow and small, and the sides of the ship are relatively low. It has always been unsatisfactory when using the lifting type and the stern slide type to support the small boat. , and the safety is not enough, the use of the stern slide type retractable operation will inevitably affect and block the observation line of sight and occu...

Problems solved by technology

The existing ship-borne small boat retractable devices mainly include the lifting type and the stern slide type. Many small tonnage ships, especially some inland waterway ships, such as sightseeing boats, fishery and sea surveillance executive ships, and small construction operations Ships, the decks of these ships are narrow and small, and the sides of the ship are relatively low. It has always been unsatisfactory when using the lifting type and the stern slide type to support the small boat. , and the safety is not enough, the use of the stern slide type retractable operation will inevitably affect and block the observation line of sight and occupy a limited deck space area, and it is not suitable, so the above-mentioned ships often use the leash to tow the small boat when traveling. method, but this method is not safe and does not comply with the regulations
