Abstract

The invention discloses an improved fork type self-locking safety lifting hook. The upper end of a lifting hook body is provided with a lifting shaft and a lifting shaft locking pin, the middle part of the lifting hook body is connected with a hanging hook body by using a connecting shaft, and a closing opening is formed between the lower end of the lifting hook body and the lower end of the hanging hook body; and a lifting hook spring lock and a spring locking pin shaft are mounted in a groove in the left side of the hanging hook body. The improved fork type self-locking safety lifting hook has following beneficial effects: a lifting hook seal is automatically locked when cargos are hoisted such that a lifting rope does not fall down from the lifting hook; safety of operators and cargos on the scene is ensured; operation is performed conveniently and quickly; and the improved fork type self-locking safety lifting hook is also advantaged by being low in cost and high in efficiency.

Description

The V shape self-locking safety hook improved

Technical field

The present invention relates to the V shape self-locking safety hook of the rigging improvement that the industries such as a kind of applicable mining machinery, shipbuilding navigation use.

Background technology

At present hanging hook mostly be opened type, although mounting is convenient, but in hanging uses, very easily cause unhook when buffering, often repeatedly repeatedly to mount in one goods of hanging, not only bother but also there is potential safety hazard, be likely to result in goods drop damage and site operation personnel's personal injury, as hanging hook made machinery sealing type, using middle safety, but making troubles but to mounting, decoupling device, extending the lifting goods time, labor efficiency reduces. Summary of the invention

In order to solve problem set forth above, the present invention provides the V shape self-locking safety hook of the improvement of a kind of improvement, the V shape self-locking safety hook of this improvement, can when lifting goods automatically by suspension hook sealing locking, make lifting rope will not come off from suspension hook, guaranteeing the safety of Field Force and goods, convenient to operation, cost is low, efficiency is high.

The object of the present invention is achieved like this, the V shape self-locking safety hook improved, equipped with hanging axis and hanging axis locking pin on hook, middle part is connected with Hook with connecting axle, lower end and Hook lower end Guan Bi mouth, equipped with suspension hook springlock in groove on the left of Hook, springlock bearing pin, during use, hang on crane stay cord with hanging axis, moving downwards suspension hook springlock makes Hook separate opening and closing mouth with hook, the Guan Bi mouth opened between Hook and hook hangs up goods stay cord to Hook, close up the opening and closing mouth of Hook and hook, unclasp suspension hook springlock, suspension hook springlock self-return is by Hook and hook locking, lifting operation can be carried out, quick convenient, safe and reliable.

It is a feature of the present invention that the elastic self-locked of employing, manually pluck latch mechanism, mounting is sling and will not be broken off relations, it is ensured that hoisting process is safe and reliable, and decoupling device is quick.

Accompanying drawing explanation

Figure is the structural representation of V shape self-locking hook of the present invention.

In figure: 1, hanging axis; 2, hanging axis locking pin; 3, hook; 4, axle is connected; 5, suspension hook springlock; 6, springlock bearing pin; 7, Hook; 8, Guan Bi mouth.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

In the view, hook 3 upper end is equipped with hanging axis 1 and hanging axis locking pin 2, middle part connects axle 4 and is connected with Hook 7, lower end and Hook lower end Guan Bi mouth 8, equipped with suspension hook springlock 5 in groove on the left of Hook 7, springlock bearing pin 6, during use, hang on crane stay cord with hanging axis 1, moving downwards suspension hook springlock 5 makes Hook 7 separate opening and closing mouth 8 with hook 3, the Guan Bi mouth 8 opened between Hook 7 and hook 3 hangs up goods stay cord to Hook 7, close up the opening and closing mouth 8 of Hook 7 and hook 3, unclasp suspension hook springlock 5, Hook 7 and hook 3 are locked by suspension hook springlock 5 self-return, lifting operation can be carried out, quick convenient, safe and reliable.
