Abstract
The utility model discloses a lifting suspension hook dropping-prevention safety device, comprising a suspension hook, a hook head, a holt hoop iron and pawls, a magnet is fixed on the suspension hook by the holt hoop iron, the pawls are connected with the hook head by a pin, one end of the pawls abuts against the magnet, the other end abuts against the hook head, in this way, the pawls automatically reset and close by the magnetic force effect of the magnet, the pawls can rotate inwards and can not rotate outwards, thereby achieving the dropping-prevention effect, and being durable, convenient and economic and reliable.
Description
Technical field
The utility model relates to a kind of safety device of load hook.
Background technology
Suspension hook is a suspender commonly used in the weight-lifting equipment, and the quality 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 hook, 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-rope releaser of this kind form is: because the frequent unlatching of ratchet makes spring tired easily, 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.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of load hook anticreep rope safety device of more durable, convenient and economic and reliable.
In order to solve the problems of the technologies described above, a kind of load hook anticreep rope safety device of the present utility model, comprise suspension hook, gib head, anchor ear, ratchet, be fixed with magnetic substance by anchor ear on the described suspension hook, described ratchet is connected with gib head by bearing pin, one end of ratchet is near magnetic substance, and the other end is near gib head.
The beneficial effects of the utility model are: this load hook anticreep rope safety device is owing to adopted said structure, can make the ratchet closure that automatically resets by the magnetic action of magnetic substance, ratchet can only inwardly rotate and can not be to inner rotary, thereby played the effect of anticreep rope, and more durable, convenient and economic and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of load hook anticreep rope safety device of the present utility model, comprise suspension hook 6, gib head 5, anchor ear 1, ratchet 4, be fixed with magnetic substance 2 by anchor ear 1 on the described suspension hook 6, described ratchet 4 is connected with gib head 5 by bearing pin 3, one end of ratchet 4 is near magnetic substance 2, and the other end is near gib head 5.This load hook anticreep rope safety device is owing to adopted said structure, can make ratchet 4 closure that automatically resets by the magnetic action of magnetic substance 2, ratchet 4 can only inwardly rotate and can not be to inner rotary, thereby played the effect of anticreep rope, and planted more durable, convenient and economic and reliable.
