Embodiment 1

[0037] Such as Figures 1 to 6 Shown is an embodiment of a ship's reversible radar mast adopting a gravity self-resetting structure of the present invention, including a main mast body platform 1, a pair of spaced apart reversible masts arranged on the main mast body platform 1 The base 2 is erected to set the inverted mast 3 between the pair of inverted mast bases 2, and the inverted mast 3 is respectively rotatably connected with the pair of inverted mast bases 2 through the rotating shaft 4. The lower end of the inverted mast 3 is connected with a counterweight 5 , and the main mast body platform 1 is also erected with an inverted mast shelf 6 , which is supported on the inverted mast shelf 6 when the inverted mast 3 falls down. Above, the main mast body platform 1 is provided with a hand winch 7, the retractable wire rope 8 of the hand winch 7 is connected with the upper end of the inverted mast 3, through the hand winch 7 and the The pulling of the retractable wire rope ...

Embodiment 2

[0057] A ship's reversible radar mast adopting a gravity self-resetting structure in Example 1 was applied to a 7,000-ton wood chip ship, which effectively improved the navigation of the ship, and the use of a manual winch combined with gravity to realize the dumping of the reversible radar mast Compared with electric winch and hydraulic equipment, it has remarkable economy. This scheme can also be generally applied to other ships with similar needs.

Abstract

The invention relates to the technical field of ship radar masts, and discloses a ship's reversible radar mast adopting a gravity self-resetting structure, including a main mast body platform and a pair of spaced apart reversible radar masts arranged on the main mast body platform. The mast base, the upright mast between the pair of upright mast bases, the upright mast is respectively rotatably connected with the pair of downmast bases through the rotating shaft, and the lower end of the downmast is connected There is a counterweight, and a downmast shelf is erected on the main mast body platform, and the backmast body platform is supported on the backmast shelf when the downmast is down, and the main mast body platform is provided with A hand winch, the retractable steel wire rope of the hand winch is connected with the upper end of the upright mast, and the falling down of the downmast is realized by pulling the hand winch and the retractable wire rope. The invention simplifies the structure of the existing reversible radar mast, reduces the cost of the radar mast and facilitates the maintenance of the radar mast.

Description

technical field [0001] The invention relates to the technical field of ship radar masts, in particular to a reversible ship radar mast adopting a gravity self-resetting structure. Background technique [0002] The radar mast is an important configuration of the ship, which integrates various equipment such as radar, antenna, signal light, and siren. In order to meet the specification requirements of signal lights, antennas, and radars, the radar mast is generally very high and needs to be installed on the top of the ship's superstructure, at the highest point of the ship. And some ships need to pass under some bridges during navigation. When the height below the bridge is less than the height of the ship at the maximum draft, the radar mast will collide with the bridge, causing a major accident. Therefore these impassable ships will not be able to operate in this area. [0003] In view of the above problems, the prior art has also developed a radar mast with a reversible s...
