Abstract

The utility model discloses an automatic mast lowering mechanism which is characterized in that the automatic mast lowering mechanism is provided with a mast tabernacle and a mast; the lower end of the mast is rotationally articulated with the mast tabernacle; one side of the mast is provided with an eye plate, while the other side thereof is provided with two eye plates; a deck at the two sides of the mast is respectively and correspondingly provided with an electric winch and two electric winches; and steep ropes connected with the eye plates are arranged on reel plates of the electric winches. The automatic mast lowering mechanism can ensure a radar mast structure to be lowered automatically before passing a big bridge; the net height of a ship after the lowering of the mast is less than 34m; the top of a mast body can not be higher than the larboard and the starboard of a ship and can fast restore after the ship passes the big bridge so as to ensure the possibility and safety of continuing sailing.

Description

Automatic movable mast mechanism

Technical field:

The utility model relates to ship domain, automatic movable mast mechanism on a kind of specifically ship.

Background technology:

The geographic position of China a lot of shipbuilding enterprise is in zone, the middle and lower reach of Yangtze River, the height of water is bigger, the seagoing vessel of being built is in going to Huanghai Sea trial voyage or flight road, must stride Jiang Daqiao through too much seat, Nanjing Yangtze River Bridge (Nanjing bridge one bridge) particularly, because design and build the age early, body of a bridge Lijiang River face is lower, and is the harshest to the requirement for height of the large ship of dealing.For example domestic in recent years 12000 tons of high-mobility, multipurpose, wheeled vehicle series ships undertaking the construction of, on the Changjiang river, belonged to large ship, its hull baseline to Luo Jing altitude above deck is 27.60m, radar mast height 11.80m on the Luo Jing deck, both additions surpass 38m, and bridge one bridge in Nanjing requires the free height of boats and ships for guaranteeing that boats and ships can pass through bridge smoothly, must could assemble the radar mast structure by behind the bridge at this ship greater than 34m.In addition, during owing to ship trial, all running lights and indicator lamp must be intact, and a large amount of running lights is but arranged on the radar mast structure, are the integral type radar mast at original design, imagination customized design one split type automatic movable mast of cover and automatic restoring mechanism.Paved road for solving above-mentioned contradiction.

Summary of the invention:

For solving the problem that prior art exists, the utility model provides a kind of automatic movable mast mechanism, make the radar mast structure before crossing bridge, can fall automatically, fell the free height of back boats and ships less than 34m, and mast body top must not surpass the port and starboard of boats and ships, treat that boats and ships pass through bridge after, quick-recovery guarantees to continue the possibility and the safety of navigation soon.

The technical solution adopted in the utility model:

Automatic movable mast mechanism, it is characterized in that: have mast step and mast, described mast lower end is hinged on the mast step; Mast one side is equipped with an eye plate, and opposite side has two eye plates, on the boat deck of mast both sides respectively correspondence an electric winch, two electric winches are installed, install around the cable wire that is connected on the eye plate on the reel of electric winch.

Advantage of the present utility model:

The automatic movable mast mechanism that the utility model provides, can guarantee that the radar mast structure is before crossing bridge, can fall automatically, the free height of boats and ships was less than 34m after falling, mast body top must not surpass the port and starboard of boats and ships, after treating that boats and ships pass through bridge, quick-recovery guarantees to continue the possibility and the safety of navigation soon.
