Operation principle:
1, lifeboat safety hook is in locking state:
See Fig. 2-Fig. 8, during lifting, with hands rotation manual nut 3.4, the second cursor 3.3 in second rotary shaft 3.1 makes retaining mechanism 4 be in locked position, main suspension hook 5, under the effect of rope pulling force F1, is in vertical operating mode, and the lower surface of main suspension hook 5 contacts with the upper fixture block 4.2.1 on locking arm 4.2, at this moment, main suspension hook 5 arm 4.2 that is locked blocks.Control bar 2.7 to be connected with hydraulic system, control bar 2.7 by downward pulling force F2, controlling bar 2.7 drives the first cursor 2.3 to make the first rotary shaft 2.1 rotate 27.5 degree, arrow on instruction block 2.2 points to symbol word marking " lock ", drive link 2.6 can move along the arc orbit 3.2.1 of rotation dish 3.2, plays a part locking.At this moment, the upper involute surface on cam 2.6 gradually contacts with rotation dish 3.2 outer round surface, and is gradually increased wedging power and frictional force, so that lifeboat safety hook is in double security insurance situation.
2, lifeboat safety hook is in released state:
See Fig. 9-Figure 15, after slinging work terminates, to discharge rope in time, control bar 2.7 and be subject to thrust F3 upwards, it makes the first rotary shaft 2.1 rotate clockwise 27.5 degree, arrow on instruction block 2.2 points to symbol word marking " unlock ", drive link 2.6 departs from the arc orbit 3.2.1 of rotation dish 3.2, and when rotation dish 3.2 rotates 90 degree, the second rotary shaft 3.1 also rotates 90 degree, locking arm 4.2 can rotate clockwise about 15 degree, and contacts with the second rotary shaft 3.1.Owing to locking arm 4.2 has rotated clockwise 15 degree, main suspension hook 5 under external force, can rotate counterclockwise about 60 degree, and rope departs from.Second rotary shaft 3.1 can only rotate 90 degree, this is because, when the second rotary shaft 3.1 turns to 90 degree, the lower involute surface on cam 2.4 can gradually periphery with rotation dish 3.2 contact, and the frictional force on two surfaces is rotated further stoping the second rotary shaft 3.1.
