A method of retracting and launching a small boat

Abstract

The invention discloses a device and method for storing small boats. Cabins for storing the small boats are arranged on a boat body of the device, a channel which tilts downwards is formed in the stern portion of the boat body, one end of the channel is connected with the cabins, and a stern door which can rotate downwards is hinged to the other end of the channel. The stern door, the channel and the cabins are respectively provided with an idler roller set which is composed of a plurality of pairs of idler rollers supporting the bottoms of the small boats from the two sides. The two sides of the idler roller set on the cabins are respectively provided with a mobile guide rail, the mobile guide rail on each side is provided with a trolley, and each trolley is provided with a traction device and a boat pushing device. According to the device and method for storing the small boats, the stern door can be rotated downwards, the small boats can slide to the boat body from the idler roller set on the stern door through the channel, then the trolleys are used for pushing the small boats to the corresponding positions of the small boats to be fixed, operation is convenient, the purpose that the storing device in one mother boat can be used for storing a plurality of small boats, operation is convenient, and the safety is high.

Description

technical field [0001] The invention relates to a device and a method for retracting small boats on a mother ship, in particular to a device and a method for retracting and storing multiple small boats on a mother ship. Background technique [0002] In order to make up for the low speed of large ships and the inability to perform tasks in shallow waters or narrow waters due to their large hulls, large ships are often equipped with some small working boats to meet the requirements of shallow and narrow waters. The launching and recovery of these small boats need to be carried out by special small boat retracting devices. Existing dinghy retractable device mainly contains hoisting type and stern slideway type. The hoisting type small boat retractable device places the small boat on the hanger, and realizes the small boat retraction by swinging the hanger along the side of the ship. It is cumbersome to carry out the retracting operation, the speed is slow, and the safety is n...

AI Technical Summary

Problems solved by technology

However, the existing stern slide type small boat retractable device and retractable method can only carry out retractable operations for a single small boat, and cannot yet carry out retractable operations for multiple small boats. With the development of ship operations , the mother ship often needs to be equipped with multiple working dinghies, so a dinghy retracting device and method capable of simultaneously retracting and retracting multiple dinghies has become a need.
