Abstract
The utility model discloses a kind of counterweight self-locking suspension hook, including by hook neck, hook body and the integrally formed suspension hook of gib head, neck is provided with the inner side of gib head, self-locking mechanism is hinged with hook neck, the self-locking mechanism includes the counterweight square frame being set on hook neck, the counterweight square frame is by hinge on hook neck, the grab being engaged with neck is integrally formed with counterweight square frame one end mutually close with gib head, in the presence of the deadweight of counterweight square frame, counterweight square frame rotates around bearing pin and grab end is stuck in neck；Counterweight square frame and grab form the lever using bearing pin as fulcrum, then in the presence of the deadweight of counterweight square frame, counterweight square frame rotates around bearing pin and causes grab end automatic clamping in neck, more more convenient than the use of original torsion spring, and the life-span is also grown.On the other hand, the more original tagger formula safety card of grab is more wear-resisting, and service life is also grown.Compact overall structure, it is practical.
Description
Technical field
The utility model belongs to technical field of crane equipment, more particularly to a kind of counterweight self-locking suspension hook.
Background technology
Traditional suspension hook blocking device is typically made up of safety card, double torsion spring and bearing pin.Under normal circumstances, in double torsions
In the presence of spring torsion, safety card is held out against on suspension hook gib head inwall, to prevent hoist cable from deviating from out of suspension hook, avoids handling thing
Therefore generation.It is tagger yet with safety card, after frequently being contacted with steel wire rope, hook, spring failure, peace often occurs
The problems such as full card deformation, so as to lose due barrier propterty.Need often to change and safeguard.
The content of the invention
The utility model is to provide a kind of counterweight self-locking suspension hook, to reach the technical scheme that above-mentioned purpose is taken
It is：A kind of counterweight self-locking suspension hook, including by hook neck, hook body and the integrally formed suspension hook of gib head, card is provided with the inner side of gib head
Groove, is hinged with self-locking mechanism on hook neck, and the self-locking mechanism includes the counterweight square frame being set on hook neck, the counterweight square frame
By hinge on hook neck, the grab being engaged with neck is integrally formed with counterweight square frame one end mutually close with gib head,
In the presence of the deadweight of counterweight square frame, counterweight square frame rotates around bearing pin and grab end is stuck in neck.
Preferably, the center of gravity of the counterweight square frame is located remotely from the side of gib head, and in one of counterweight square frame away from gib head
End is provided with handle.
Preferably, the curved shape of the grab is engaged with the shape on the inside of hook body.
Had the beneficial effect that possessed by the utility model：Counterweight square frame and grab form the lever using bearing pin as fulcrum, then
In the presence of the deadweight of counterweight square frame, counterweight square frame rotates around bearing pin and causes grab end automatic clamping in neck, than original
The use of torsion spring is more convenient, and the life-span is also grown.On the other hand, the more original tagger formula safety card of grab is more wear-resisting, uses
Life-span is also grown.Compact overall structure, it is practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of counterweight self-locking suspension hook, including by 1 integrally formed suspension hook of hook neck 4, hook body 7 and gib head,
Neck is provided with the inner side of gib head 1（Not shown in figure）, self-locking mechanism is hinged with hook neck 4, the self-locking mechanism includes set
The counterweight square frame 5 being located on hook neck 4, the counterweight square frame 5 is hinged on hook neck 4 by bearing pin 3, in counterweight square frame 5 and gib head 1
Mutually close one end is integrally formed with the grab 2 being engaged with neck, and in the presence of the deadweight of counterweight square frame 5, counterweight square frame 5 is around pin
Axle 3 rotates and so that the end of grab 2 is stuck in neck.
In order to realize auto lock, the center of gravity of the counterweight square frame 5 is located remotely from the side of gib head 1, and in counterweight square frame 5
One end away from gib head 1 is provided with handle（It is not drawn into figure）.
In order to which when lifting counterweight square frame 5, grab 2 is put into suspension hook closer to hook body 7 without influenceing hoist cable, the card
The curved shape of hook 2 is engaged with the shape of the upper inner 6 of hook body 7.
The utility model when in use, lifts counterweight square frame 5 with hand first, and grab 2 puts hoist cable close to the inner side of hook body 7
Enter in suspension hook, put down counterweight square frame 5, in the presence of the deadweight of counterweight square frame 5, counterweight square frame 5 rotates around bearing pin 3 and causes grab
2 ends are stuck in neck, so as to be played a protective role to hoist cable.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent change and modification that the technical essence of the utility model is made to above example, belongs to this reality
With the protection domain of new technique scheme.
