Abstract
The utility model discloses lifting hook anticreep rope safeties relates to jack-up hoist technical field. The magnetic body is installed on the lifting hook by using the hoop, the pawl is fixed by using the pin shaft, and the pawl is reset by magnetic force, so that the rope is limited to slide out, and the lifting hook is used for various lifting hooks.
Description
Affiliated technical field
The utility model load hook anticreep rope safety device relates to the hoisting sling technical field.
Background technology
Suspension hook is a suspender commonly used in the weight-lifting equipment, is important components, and the good job of its safety performance directly influences the safe in utilization and operating personnel's of weight-lifting equipment personal safety.The countries concerned's standard or industry standard all require load hook to have and prevent the anti-rope releaser that hoist rope skids off from suspension hooks, and the mode that present load hook adopts ratchet to add extension spring or torsion spring is usually formed anti-rope releaser.The shortcoming of the anti-drop device of this kind form is: because the frequent unlatching of ratchet makes spring very easily tired, cause inefficacy, need often to keep in repair or change, bring very big inconvenience to use, increased the safety hazard of use cost and use.Therefore in use be sought after a kind of more durable, and anti-rope releaser convenient, economic and reliable.
Summary of the invention
In order to overcome existing the problems referred to above in the existing anti-rope releaser, it is a kind of by magneto motive load hook anticreep rope safety device that the utility model provides.
The technical scheme that its technical matters that solves the utility model adopts is: fix a magnetic substance with anchor ear on suspension hook, ratchet is connected with gib head by bearing pin, because the effect of magnetic force, an end of ratchet is all the time near magnetic substance, the other end is then near gib head, and suspension hook is in closure state.When the lanyard rope, as long as on ratchet, apply certain power, ratchet is opened, thereby make rope enter gib head, again owing to the effect of magnetic force, the ratchet closure that will automatically reset, ratchet can only inwardly rotate, can not be to inner rotary, thus played the effect of anticreep rope.
The beneficial effects of the utility model are that ratchet can automatically reset economy and durability when the lanyard rope.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
This figure is a design sketch of the present utility model.
1. anchor ears among the figure, 2. magnetic substance, 3. bearing pin, 4. ratchet, 5. gib head.
The specific embodiment
Magnetic substance among the figure (2) is close together by anchor ear (1) and gib head (5), and ratchet (4) is connected with gib head (5) by bearing pin (3), and ratchet (4) is connected with gib head (5) by bearing pin (3).
When rope from gib head (5) when entering, on ratchet (4), apply certain power, overcome the magnetic action of magnetic substance (2), ratchet (4) is Unscrew inwardly, thereby make rope enter gib head (5), external force is cancelled, because the effect of magnetic substance (2) magnetic force, ratchet (4) will automatically reset, and rope is played the anticreep effect.
Claims (2)
1, a kind of load hook anticreep rope safety device, it comprises: anchor ear (1), magnetic substance (2), bearing pin (3), ratchet (4), gib head (5), it is characterized in that: on suspension hook, fix a magnetic substance with anchor ear, ratchet is connected with gib head by bearing pin, magnetic force makes an end of ratchet all the time near magnetic substance, and the other end is then near gib head.
2, load hook anticreep rope safety device according to claim 1 is characterized in that: prevent that rope from coming off in the suspension hook is magnetic action by magnetic substance.
