Crane is widely used when carrying, hoisting large-size or heavy object; if the suspension hook of crane guarantees lifting safety; important safety guard is generally installed on the suspension hook of crane; namely it is Anti-hook releasing device; but the Anti-hook releasing device used by crane at present; in the process used when rope is too thick; tongue pressure is not gone down; rope can not be won out; workplace altofrequency is linked up with, won, in order to improve work efficiency, hook is often destroyed by workman by force; win, cause great potential safety hazard.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of Anti-hook releasing device.
Invention thought of the present utility model is: this utility model Anti-hook releasing device used by current crane, in the process used when rope is too thick, tongue pressure is not gone down, rope can not be won out, altofrequency is linked up with, the workplace won, in order to improve work efficiency, hook is often destroyed by workman by force, win, cause great potential safety hazard, and then propose a kind of Anti-hook releasing device, including the hook body being made up of suspension hook and suspension hook handle, at described suspension hook upper opening portion, bearing pin is set, two the aerofoil profile gag lever posts being rotating shaft with described bearing pin are set at described bearing pin two ends, described bearing pin both ends are also respectively sleeved on torsion spring, one end of described torsion spring connects described gag lever post, other end connecting shackle handle.
A kind of Anti-hook releasing device, including the hook body being made up of suspension hook and suspension hook handle, wherein, at described suspension hook upper opening portion, bearing pin is set, two the aerofoil profile gag lever posts being rotating shaft with described bearing pin are set at described bearing pin two ends, described bearing pin both ends are also respectively sleeved on torsion spring, and one end of described torsion spring connects described gag lever post, other end connecting shackle handle.
Said two aerofoil profile gag lever post lays respectively at described suspension hook opening both sides.
Said two aerofoil profile gag lever post is respectively provided with the link of fixing described one end.
Described suspension hook is provided with the link connecting the described torsion spring other end.
The banking stop hindering described torsion spring to come off is set at described bearing pin two ends.
When this utility model uses, when rope is linked in suspension hook by needs, hands rotating airfoils gag lever post, under the effect of torsion spring, aerofoil profile gag lever post being placed in suspension hook side, suspension hook opening is opened, rope is linked in suspension hook, hands rotating airfoils gag lever post, aerofoil profile gag lever post is placed in suspension hook opening both sides, and suspension hook opening closes, when rope won by needs, aerofoil profile gag lever post is placed in suspension hook side, and suspension hook opening is opened, and is won by rope.
The beneficial effects of the utility model are: facilitate the hook of rope and win, solve in use when rope is too thick, obstruction because of tongue, do not enter the problem can not won out in suspension hook with rope, the workplace link up with for rope altofrequency, won, improves work efficiency, it is to avoid suspension hook is destroyed by workman by force, realize winning of rope, cause great security hidden trouble.
