Embodiment Construction

[0025] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0026] Such as figure 1 , figure 2 with image 3 Shown, a kind of fast lowering and recovering device by ball, it comprises boom 10; Boom 10 comprises two support arms 11 and transverse arm 12 that is fixed between two support arms, and support arm 11 is hinged on deck 20. The support arm 11 is a bent arm.

[0027] Two jib bases 14 are fixed on the deck 20 , and the bottoms of the two support arms 11 are respectively hinged to the two jib bases 14 .

[0028] The fast landing and recovery device by the ball also includes an oil cylinder 13 that can rotate the support arm and keep the support arm stationary relative to the deck; there are two oil cylinders 13, and the tops of the two oil cylinders are respectively hinged on the two support arms 11 , the bottoms of the two oil cylinders 13 are hinged to t...

Abstract

The invention discloses a quick descending and recovering device for a leaning ball. The quick descending and recovering device comprises an arm frame; the arm frame comprises two supporting arms and a transverse arm fixedly arranged between the two supporting arms, and the supporting arms are hinged to the deck; the quick descending and recovering device for the leaning ball further comprises oil cylinders which can enable the supporting arms to rotate and enable the supporting arms to be kept in a static state relative to the deck. The number of the oil cylinders is two, the tops of the two oil cylinders are hinged to the two supporting arms respectively, and the bottoms of the two oil cylinders are hinged to the deck respectively. And a hoisting mechanism for controlling the leaning ball to ascend or descend is arranged on the arm frame. According to the invention, the working efficiency is improved, the occupied deck area is reduced, and the working intensity of personnel is reduced; the investment cost is low.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a device for quickly lowering and recovering balls. Background technique [0002] As a clean energy source, the use of liquefied natural gas (LNG) has been adopted in all walks of life in the world. In the shipping industry, there are more and more LNG carriers and LNG-powered sailing ships. With the increasing tonnage of LNG carriers and LNG-powered sailing ships, most of the world's LNG bunkering The capacity of the terminal cannot be upgraded or replaced in a short period of time, so the LNG bunkering ship came into being. [0003] Before the operation of the LNG bunkering ship, ship-to-ship mooring operations are required so that the two ships can approach safely. [0004] The arrangement scheme of the existing bunkering ball is mainly determined by the use method, and there are three mainstream methods. [0005] The first method is centralized arrangement by means of balls,...
