The utility model has the advantages that the lifting hook lifts by crane in-process safe and reliable, proclaims oneself the rocking arm and only can open when the manual operation, easy operation has avoided being hung the accident that the thing drops from the hook groove.

Description

Pull open in the self-sealing and open suspension hook
Technical background
The utility model belongs to a kind of suspension hook, pulls open in particularly a kind of self-sealing and opens suspension hook.
Background technology
The existing load hook that uses generally adopts open type or reed seal type, in use the shortcoming of Cun Zaiing is: during by lifting object or object scratching on every side, because of making weight, the elastic reaction of steel rope produces inertia upwards, cause hanging object to collapse in the suspension hook groove or break reed, the particularly swipe of oil well in playing the lower tubular column operation, elevator is ejected in the suspension hook groove, lead to a disaster.
The utility model content
The purpose of this utility model provides to pull open in a kind of self-sealing and opens suspension hook, and suspension hook is safe and reliable in the lifting process, and self-styled rocking arm only could be opened when manual operation, and is simple to operate, has avoided suspended object to come off from the hook groove and has an accident.
The purpose of this utility model is achieved by the following technical solution: it comprises lifting ring, jam nut, spiral vertical shaft and suspension hook, it is characterized in that: at the hinged self-styled rocking arm of suspension hook opening part, an end of hinged spanner in suspension hook, the other end of spanner plate one end that is articulated and connected, the hinged self-styled rocking arm of the connecting panel other end is at the dorsal part assembling spring of spanner.
The utility model has the advantages that: suspension hook is safe and reliable in the lifting process, and self-styled rocking arm only could be opened when manual operation, and is simple to operate, the accident of having avoided suspended object to come off from the hook groove.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, concrete structure of the present utility model is: lifting ring 5 is by jam nut 6 and spiral vertical shaft 7 suspension hook 13 that is rotationally connected.13 opening part is by hinge 8 hinged self-styled rocking arms 12 on suspension hook.Assembling spanner 3 in suspension hook 13, package assembly is: an end of spanner 3 is hinged on the suspension hook 13 by hinge 1, and the other end of spanner 3 is by hinge 9 plate 11 1 ends that are articulated and connected, and connecting panel 11 other ends are by hinge 10 hinged self-styled rocking arms 12.Act on the leaf spring 4 of spanner 3 in the dorsal part assembling of spanner 3.Leaf spring 4 is to be assembled on the suspension hook 13 by adapter shaft 2.During use, because the effect of spring 4 is arranged, the interlock effect of spanner 3 by connecting panel 11 makes self-styled rocking arm 12 that the mouth of hook is self-styled.During unlatching, pull spanner 3 with hand, the interlock effect by connecting panel 11 is rotated self-styled rocking arm 12, and the mouth of hook is opened.
