3, in the process of step 4, to position 2. (as shown in Figure 8) 1. rescue craft can rotate from position, and under the effect of rescue craft position limit auxiliary device of the present invention, rescue craft can be limited in a very little interior swing of scope all the time.When in-position 2. time, the spacing of horizontal support bar with balance under, rescue craft fore can reach the angle of release request very soon.
4, after reaching ideal position, just can directly discharge ship and hang hoist cable.In dropping process, auxiliary rod can not rotate with the decline of ship always, when auxiliary rod angle reaches capacity position, the collar will progressively from L-type hook Automatic-falling.Need not break off relations manually, not only convenient but also safety, and the time of release ship can not be increased.
Under the present invention utilizes horizontal support bar and ship to be hung in the effect of two disloyalty circumference, by the mutual balance of power, reach the auxiliary object rotating rescue craft, and rescue craft can be helped to limit hunting range, mutually collide to avoid ship and other equipment.
Compared with prior art, beneficial effect of the present invention is:
1, the present invention no longer needs manpower to control the trend of ship in rescue craft rotary course; avoid ship in rotary course because artificial origin causes the angular adjustment of ship excessive; in rotary course; owing to decreasing the swing of ship; avoid crewman to fall into water, the crewman on ship is played a very good protection.
2, decrease operating personal, only need a sailor just can complete the operation of release rescue craft.
