Description
Technical field
The invention belongs to suspension hook equipment technical field, and in particular to a kind of self-locking crane hook.
Background technology
Hoisting machinery use universal in various engineering constructions, construction safety turn into the most important thing, so prevention is various
Unexpected is indispensable, is especially lifted on the weight in high-altitude, the article of suspension hook lifting is particularly important safely, tradition
Suspension hook lifting rope is locked using hand, this hand suspension hook needs using manually unlocking, using when in use
When it is very inconvenient, the labor intensity of worker is big, on the other hand, exploitation it is a kind of it is simple in construction, easy to use, labor intensity is small, operation into
This low self-locking crane hook tool is of great significance.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and provide a kind of simple in construction, easy to use, work
The self-locking crane hook that intensity is small, operating cost is low.
The object of the present invention is achieved like this：A kind of self-locking crane hook, it includes hook body, and described hangs
The bottom of hook body is provided with cavity, and spring base is connected with described cavity, and the upper end of described spring base is connected with load-bearing
Plate, described bearing plate are arcuate structure, and the bottom of spring base is connected with spring, and lower end and the hook body of described spring connect
Connect, layback plate is provided with the outer wall in the middle part of spring base, the lower hinge of described layback plate has self-locking plate, described self-locking plate
Bottom be connected by bearing pin with hook body.
Described spring base is connected by way of welding with bearing plate.
The bottom of described spring base is provided with the hollow cavity being engaged with spring.
Described layback plate is obliquely installed, and angle of inclination is 15 ° -30 °.
Described self-locking plate is arranged on the inside of cavity.
The opening being engaged with self-locking plate is provided with the medial surface of described hook body.
Beneficial effects of the present invention：In the use of the present invention, spring is in free elongation state, spring before hoisting heavy
Top is higher by the minimum point with hook body to seat under the action of the spring, when in hoisting heavy, effect of the bearing plate in weight
Under move down, i.e., spring base moves down with bearing plate, and spring is in compressive state, during spring base moves down
Layback strip is moved self-locking plate and rotated, when spring base is moved down into certain position, self-locking plate just opening hook body
Mouthful block, form the space of a closing, complete auto-lock process, when needing to unload loads, hook body moves down, when holding
When weight plate departs from the pressure of weight, spring base moves up under the elastic force of spring, while layback strip moves self-locking sheet reset, solution
Except self-locking, the present invention has the advantages of simple in construction, easy to use, labor intensity is small, operating cost is low.
Brief description of the drawings
Fig. 1 is a kind of structural representation of self-locking crane hook of the present invention.
In figure：1st, hook body 2, cavity 3, spring base 4, bearing plate 5, spring 6, layback plate 7, self-locking
Plate.
