Gib head rotates the number of turns and coordinated more than with suspension hook locknut after the number of turns, and suspension hook gib head drops the goods together with lifting, there is pole
Big potential safety hazard.To prevent the generation of such security incident, it is quite necessary to which existing suspension hook is improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device for preventing crane hook gib head from releasing, this
Planting device can also prevent suspension hook gib head from occurring with suspension hook locknut relative in the case of suspension hook locknut clamp bolt looseness
Rotate, therefore reach and prevent the purpose of suspension hook gib head loose or dislocation.
Solving the technical scheme of above-mentioned technical problem is：
A kind of device for preventing crane hook gib head from releasing, it by suspension hook gib head, suspension hook locknut, suspension hook locknut clamp,
Suspension hook locknut clamp bolt is constituted, and suspension hook locknut is connected with suspension hook gib head spiral, and suspension hook locknut clamp is located at suspension hook locknut and hung
The upper surface of hook gib head, suspension hook locknut clamp two ends are bolted on the top surface of suspension hook locknut by suspension hook locknut clamp, and it changes
Entering part is, the section of suspension hook locknut clamp is trapezoidal, on the upper surface of suspension hook gib head and the upper surface of suspension hook locknut respectively
It is machined with the trapezoidal dovetailed cross section and suspension hook locknut clamp of trapezoidal dovetail groove, suspension hook gib head upper surface and suspension hook locknut upper surface
Trapezoid cross section match, suspension hook locknut clamp is inlaid in the trapezoidal dovetail groove of suspension hook gib head upper surface and suspension hook locknut upper surface
In.
The above-mentioned device for preventing crane hook gib head from releasing, the suspension hook gib head upper surface and suspension hook locknut upper surface
The trapezoid cross section upper bottom edge of trapezoidal dovetail groove is trapezoidal short side, upper bottom edge and suspension hook gib head upper surface and suspension hook locknut upper surface
Flush.
The above-mentioned device for preventing crane hook gib head from releasing, the trapezoidal dovetail groove and suspension hook of the suspension hook gib head upper surface
The trapezoidal dovetail groove of locknut upper surface is integrated machine-shaping, trapezoidal dovetail groove, the suspension hook of suspension hook locknut clamp and suspension hook gib head
The trapezoidal dovetail groove of locknut is tight fit.
The beneficial effects of the utility model are：
The utility model processes trapezoidal dovetail groove, suspension hook locknut card in suspension hook gib head upper surface and suspension hook locknut upper surface
The section of plate is trapezoidal, and suspension hook locknut clamp is embedded in the trapezoidal dovetail groove of suspension hook gib head and suspension hook locknut, by suspension hook gib head
Connected as one with suspension hook locknut, the trapezoidal dovetail groove of suspension hook locknut clamp and suspension hook gib head and suspension hook locknut is fitted close, tool
There is very big frictional force, greatly limit the possibility of suspension hook locknut clamp axial float, even if suspension hook locknut clamp bolt is sent out
Raw to loosen or come off, suspension hook locknut clamp will not also be deviate from from trapezoidal dovetail groove, can be by suspension hook gib head and suspension hook locknut firmly
Locking, makes suspension hook gib head and suspension hook locknut not to unscrew and releases, it is ensured that the safe handling of suspension hook.The utility model structure
Simply, it is easy to use, anti-loose to work well, there is the value promoted the use of well.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：Suspension hook gib head 1, lifting beam with hook 2, suspension hook locknut 3, suspension hook locknut clamp 4, suspension hook locknut clamp
Bolt 5.
Embodiment
The utility model is made up of suspension hook gib head 1, suspension hook locknut 3, suspension hook locknut clamp 4, suspension hook locknut clamp bolt 5.
Shown in figure, suspension hook locknut 3 is connected with suspension hook gib head 1 using spiral, suspension hook locknut clamp 4 is located at suspension hook locknut 3
With the upper surface of suspension hook gib head 1, the two ends of suspension hook locknut clamp 4 are fixed on the top surface of suspension hook locknut 3 by suspension hook locknut clamp bolt 5
On, suspension hook gib head 1 and suspension hook locknut 3 are fastened, prevents suspension hook gib head 1 and suspension hook locknut 3 from relatively rotating, causes pine
It is de-.
In order to prevent relative turn in the loose or dislocation rear hanger gib head 1 of suspension hook locknut clamp bolt 5 and suspension hook locknut 3
Dynamic, the utility model is improved suspension hook gib head 1, suspension hook locknut 3 and suspension hook locknut clamp 4.
Shown in figure, first, suspension hook locknut clamp 4 is changed to section for trapezoidal strip clamp, meanwhile, in suspension hook hook
Trapezoidal dovetail groove is processed respectively on first 1 upper surface and the upper surface of suspension hook locknut 3, makes the upper surface of suspension hook gib head 1 and suspension hook
The trapezoid cross section of the trapezoidal dovetailed cross section of the upper surface of locknut 3 and suspension hook locknut clamp 4 matches.
Shown in figure, the trapezoid cross section upper bottom edge of the trapezoidal dovetail groove of the upper surface of suspension hook gib head 1 and the upper surface of suspension hook locknut 3
For trapezoidal short side, upper bottom edge is flushed with the upper surface of suspension hook gib head 1 and the upper surface of suspension hook locknut 3.Suspension hook locknut clamp 4 is inlaid in
In the trapezoidal dovetail groove of the upper surface of suspension hook gib head 1 and the upper surface of suspension hook locknut 3.Suspension hook gib head and suspension hook locknut are connected as one
Body.
Shown in figure, the trapezoidal dovetail groove of the upper surface of suspension hook gib head 1 is one with the trapezoidal dovetail groove of the upper surface of suspension hook locknut 3
Body machine-shaping, suspension hook locknut clamp 4 is closely to match somebody with somebody with the trapezoidal dovetail groove of suspension hook gib head 1, the trapezoidal dovetail groove of suspension hook locknut 3
Close.During processing, trapezoidal dovetail groove is processed after suspension hook gib head 1 and suspension hook locknut 3 are assembled, to prevent what is do not coordinated
Situation occurs.
Because the trapezoidal dovetail groove of suspension hook locknut clamp 4 and suspension hook gib head 1 and suspension hook locknut 3 is fitted close, with very big
Frictional force, the possibility of the axial float of suspension hook locknut clamp 4 is greatly limit, even if pine occurs for suspension hook locknut clamp bolt 5
Move or come off, suspension hook locknut clamp 4 will not also be deviate from from trapezoidal dovetail groove, can firmly lock suspension hook gib head 1 and suspension hook locknut 3
Tightly, make suspension hook gib head 1 and suspension hook locknut 3 not to unscrew to release, it is ensured that the safe handling of suspension hook.
