Foldable automatic telescopic mast system and working method thereof

Abstract

The invention relates to a foldable automatic telescopic mast system and a working method thereof. The system comprises a mast body whose lower end is hinged to the hull and can be made in an uprightor down state by swinging. The mast body comprises a plurality of mast sections with the diameters gradually decreased section by section from bottom to top, and every two vertically-adjacent mast sections are connected together in a sleeved mode and can slide relatively to achieve stretching and retracting; a plurality of winches distributed on the periphery of the mast body are installed on thehull; towropes of the winches are connected to the top of the mast body; and two winches are located on the two sides of the mast body in the swinging direction respectively. The foldable automatic telescopic mast system is adjustable in overall height and can be folded and put down, the passing height of a ship is greatly reduced, the passing ability is improved, the practicability is high, use is convenient, and operation is easy; the mast system can be folded after being contracted, so that the occupied space is reduced, and the size of the placing platform is greatly reduced.

Description

technical field [0001] The invention relates to a foldable automatic telescopic mast system and its working method. Background technique [0002] The mast is used to install equipment such as navigation lights, signal flags, lights, and sirens. Most ships only have a bow mast, and a few have a stern mast. It affects the traffic capacity of ships, increases the wind area, and is relatively difficult to maintain. [0003] Most of the existing masts are fixed, and there are certain requirements for the height of the masts, which are relatively high. When driving in some height-limited rivers and seaways, the traffic capacity of the ship will be affected; in addition, due to the signal lights installed on the mast, Navigation lights, electronic instruments, signal flags and aerosol horns need to install a lot of steel structures, which increases the wind area and affects the stability of the ship; due to the relatively high height of the mast, this increases the difficulty of m...

AI Technical Summary

Problems solved by technology

However, the telescopic mechanisms of these masts are all in the mast section, which takes up a lot of space, affects the actual telescopic space, and cannot be installed and maintained. In addition, there is no mechanical limit and reinforced mast, only the hydraulic system itself. If the hydraulic system fails , The mast retracts downward due to gravity, which seriously affects the safety of the ship and personnel. At the same time, due to safety issues, when it is actually in the stretched state, it is afraid to arrange personnel to go up for maintenance.
