The pressure self-locking formula crane hook tool high, operating cost is low is of great significance.
The content of the invention
The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, easy to use, safe
The pressure self-locking formula crane hook that performance is high, operating cost is low.
The object of the present invention is achieved like this：A kind of pressure self-locking formula crane hook, it includes hook body, described
The lower part of hook body be provided with spring groove, spring is connected with the spring groove, the upper end of the spring is connected with
Bearing seat, the bearing seat are connected on the outer wall of hook body lower part, and self-locking is socketed with the outer wall on hook body top
Device, the self-locking device are made of self-locking arm and the fixed seat hinged with self-locking arm, and the self-locking arm is L-type knot
There are connecting rod in structure, one end of the self-locking arm by bolted splice, and the other end of the connecting rod is connected with bearing seat, institute
The fixed seat stated is half ring type structure.
It is provided with the outer wall of the hook body lower part and the matched slideway of bearing seat.
The quantity of the self-locking arm is 2, and is bolted.
The quantity of the fixed seat is 2, and is symmetrical arranged.
The middle part of the connecting rod is arcuate structure.
Beneficial effects of the present invention：In the use of the present invention, fixed seat is fixed on hook body top using bolt
On outer wall, while self-locking device is connected with bearing seat using connecting rod, when hoisting heavy, effect of the steel wire cable in weight
Lower pushing bearing seat, bearing seat are being subjected to displacement after receiving pressure under, while drive one end of self-locking arm to send out by connecting rod
Give birth to bottom offset, be hinged since self-locking arm is L-type structure, and with fixed seat, when one end of self-locking arm occurs to bottom offset,
The another side of self-locking arm shifts up, and then realizes auto-lock process, and when unloading loads, bearing seat contacts the work of weight pressure
With, then reset is shifted up under the force of a spring, while connecting rod drives self-locking arm to reset, and then realize contact self-locking,
The present invention has the advantages that performance rational in infrastructure, easy to use, safe is high, operating cost is low.
