Description
Technical field
This utility model relates to a kind of crown block hook, particularly relates to a kind of crown block hook hook
Head.
Background technology
General, crown block hook is made up of gib head, hook bell, hook cap, outer housing, assembly pulley.
Directly being contacted by gib head and be lifted thing, being lifted thing is the most all the weights such as iron and steel, such as figure
Shown in 1, between the suspension hook shank 10 and the suspension hook 20 that are connected with suspension hook, bayonet socket 30 opens
Mouth degree is 55 °, and bayonet socket 30 be shaped as square aperture, when handling, the most right
Rib mouth produces and coughs up damage, causes rib mouth to damage.During such as handling steel pipe, steel pipe groove after chamfered edge
Easily it is deformed.
Summary of the invention
Technical problem to be solved in the utility model is to provide one can be by pipe end
Groove foremost and root face just can snap in suspension hook nest mouth in make its most squeezed buckling
The crown block hook gib head of shape.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of
Crown block hook gib head, the shank being connected with suspension hook including integral part of, hook portion, connection should
Shank and the kink of hook portion, described kink is oblique connection at the connection end of described shank
One end of described hook portion, and form nest mouth with described hook portion.
Described nest mouth Opening length is 6mm.
Between described kink and described hook portion, the opening degree of bayonet socket is 55 °.
The beneficial effects of the utility model are: suspension hook bayonet socket opening is that the nest mouth of 55 ° makes steel pipe
Root face and suspension hook contact site leave vacancy, directly do not contact with suspension hook, protect steel pipe rib mouth
It is not extruded, it is ensured that during handling, steel pipe groove is complete.

Detailed description of the invention
With detailed description of the invention, this utility model is made the most below in conjunction with the accompanying drawings
Bright:
Fig. 2 is schematic diagram of the present utility model.A kind of crown block hook gib head, including a bodily form
Become the shank 1 being connected with suspension hook, hook portion 2, connect this shank 1 and the bending of hook portion 2
Portion 3, described kink 3 is the described hook portion of oblique connection 2 at the connection end of described shank 1
One end, and form nest mouth 4 with described hook portion 2.Described nest mouth 4 Opening length is 6mm.
Between described kink 3 and described hook portion 2, the opening degree of opening 5 is 55 °, steel during handling
Pipe root face and suspension hook contact site leave vacancy, directly do not contact with suspension hook, protect steel pipe rib
Mouth is not extruded, and protects steel pipe rib mouth quality.
During use, suspension hook gib head is stuck in the two ends treating handling steel pipe, it is ensured that before steel pipe groove
End snaps in fishhook nest mouth, then runs overhead traveling crane handling steel pipe, and handling steel tubes is to specifying position
After, after steel pipe is kept steady, take off gib head, handling completes.
