In figure, 1. hook, 2. wiring shell, 3. set pin, 4. rotor wheel, 5. moving pin, 6. sliding tray, 7. anticreep plate, 7.1. steel rope, rope 8. breaks off relations.

The specific embodiment

Below in conjunction with specific embodiment, such scheme is described further.Should understand these embodiment is for the utility model being described rather than limiting scope of the present utility model.The implementation condition adopting in embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.

Please refer to Fig. 1 to Fig. 2, the overall structure schematic diagram that Fig. 1 provides for the utility model embodiment; The side-looking structural representation that Fig. 2 provides for the utility model embodiment.

In a kind of specific embodiment, a kind of boats and ships automatic releasing hook is provided, hook 1 is made up of connecting portion, curve and suspension hook end, is provided with set pin 3 in the suspension hook end of hook 1, and described set pin 3 setting parties are to vertical with hook 1 direction; Wiring shell 2 is installed on curve; Be provided with rotor wheel 4 in the junction of curve and connecting portion, described rotor wheel 4 setting parties are to vertical with hook 1 direction; Described set pin 3 and rotor wheel 4 are arranged on respectively wire casing 2 two ends; Be provided with sliding tray 6 at curve top, moving pin 5 be installed in sliding tray 6, described sliding tray 6 and moving pin 5 setting parties to vertical with hook 1 direction, described moving pin 5 in the interior slip of sliding tray 6; Unhook rope 8 one end are fixedly connected on set pin 3, and the rope 8 rope bodies that break off relations are located in wiring shell 2 and pass successively rotor wheel 4 and moving pin 5, and the exit of the rope 8 that breaks off relations is connected with crane auxiliary hook; Connecting portion and suspension hook end at hook 1 are provided with anticreep plate 7, and anticreep plate 7 one end are arranged on connecting portion by rotating shaft and torsion spring, and anticreep plate 7 is connected with moving pin 5 by steel rope 7.1.

Concrete, described rotor wheel 4 is arranged on hook 1 both sides by rotational pin respectively, when use, weight connection cord is arranged in hook 1, anticreep plate 7 one end under torsion spring effect is stuck in suspension hook end, by suspension hook lifting, weight is moved to relevant position, after parking steadily, hook moves down, make connection cord absent-mindedness bending, now, rise by controlling crane auxiliary hook, the rope 8 that breaks off relations drives moving pin 5 to slide to top-direction from sliding tray 6 bottoms in the drop-down direct join of crane auxiliary hook effect, moving pin 5 moves and drives anticreep plate 7 to move in hook, the torsion spring of anticreep plate 7 is extruded, rotor wheel 4 rotates simultaneously, the unhook rope 8 of both sides pulls out from wiring shell 2, because suspension hook end is lower than rotor wheel 4 height, in the time that the rope 8 that breaks off relations is straightened between set pin 3 and rotor wheel 4, crane auxiliary hook is out of service, now, the rope 8 that breaks off relations has angle of inclination, connection cord is easy to skid off in hook, after connection cord is extracted, car auxiliary hook moves downwards, and anticreep plate 7 returns bullet to suspension hook end under the antagonistic force of torsion spring, and moving pin 5 slides to bottom direction from sliding tray 6 tops under the drive of anticreep plate 7, as can be seen here, hook 1 can be plucked rope automatically, simple to operation, improves safety in utilization.

Further, described wiring shell 2 is made up of sheet metal, wiring shell 2 is arranged on respectively hook 1 curve both sides, wiring shell 2 two ends extend to respectively hook 1 suspension hook end and connecting portion, the rope 8 that makes to break off relations can be straightened completely between suspension hook end and rotor wheel 4, reach certain angle of inclination, connection cord comes off at one's leisure.

Further, the steel rope 7.1 of described anticreep plate 7 is located at hook center, and described unhook rope 8 is arranged on respectively hook 1 both sides, as can be seen here, can avoid steel rope 7.1 and the rope 8 that breaks off relations in use to interfere with each other, and affects result of use.

Finally it should be noted that the only restriction for the technical solution of the utility model is described but not to the utility model protection domain of above embodiment.Although the utility model is explained in detail with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
