Power supply and the switch for controlling on/off are connect, gag lever post is via switch control electromagnet apparatus on/off electricity in accommodating cavity
Limit function is realized in sliding between right flange.
Preferably, the length between the left and right flange is less than the length of accommodating cavity.
Preferably, the electromagnet apparatus includes iron core and the conductive winding that is wrapped in outside iron core.
Preferably, the switch is arranged in the operating room of crane.
The course of work: when crane need of work hook takes object, control switch makes to be located at the electromagnet apparatus at left flange
It being powered, the electromagnet apparatus power loss at right lugs position, electromagnet apparatus generates magnetic field control gag lever post and is moved to the left, this
When, it is hung in suspension hook wait hook the rope taken via the opening between left and right flange；When crane works transferring objects, this time control
System switch makes the electromagnet apparatus power loss at left flange, and the electromagnet apparatus at right flange is powered, and generates at electromagnet apparatus
Magnetic field controls gag lever post and is closed the opening between left and right flange, and suspension hook is enclosed a mouth by hook body and gag lever post
Shape structure, rope can not be detached from out of hook body.
Compared with prior art, the utility model has the following beneficial effects: dropping-proof hook provided by the utility model, in suspension hook
Ontology upper end is equipped with left and right flange and electromagnet apparatus, and gag lever post can realize that gag lever post is holding automatically under switch control
It sets and is slided between chamber and right flange, the opening between accommodating cavity and right flange is closed or opened, it is ensured that object is in transfer process
In will not be detached from from suspension hook, solving suspension hook in the prior art does not have disconnecting prevention structure bring security hidden trouble.

Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combination is specifically illustrating and embodiment, furthers elucidate the utility model.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of dropping-proof hook for crane, including it is whole concave around being formed via round steel
Hook body 1,1 both ends of hook body extend towards to form left and right flange 2,3, are additionally provided with vertical right flange 3 on right flange 3
And the connecting rod 4 far from 1 direction of hook body, the accommodating cavity 5 along left 2 direction of flange arrangement, accommodating cavity are additionally provided in left flange 2
Sliding is provided with gag lever post 6 between 5 left ends and right flange 3；The one end of end and accommodating cavity 5 far from right flange 3 of right flange 3 is also
Equipped with electromagnet apparatus 7,7 external power supply of electromagnet apparatus and the switch for controlling on/off, gag lever post 6 is via switch
Control 7 on/off electricity of electromagnet apparatus slides between accommodating cavity 5 and right flange 3 realizes limit function.
In the prior art, the suspension hook on crane is not provided with anti-drop structure, this is to bringing certain safety in actual job
Hidden danger, in order to avoid the rope on suspension hook falls off, also rotation is equipped with buckle on suspension hook, but the buckle needs artificial reversion, nothing
Method realizes automatic adjustment, high especially for a few thing intensity, and the working environment of pipelining is not applicable.The utility model mentions
