Abstract
The utility model relates to an antiskid mechanism for crane hooks, wherein the inner side of the rod of the hook is provided with a small hole in the direction vertical with the plane of the hook, the small hole is riveted with a pin sheathed by a tongue piece capable of swing around the pin, the pin is provided with a torsion spring whose one end abuts against the inner side of the rod of the hook and the another end abuts against the inner side of the tongue piece. Via the torsion spring, the end of the tongue piece abuts against the inner side of the hook sharp. When the rope of the crane hook overcomes the torsion force of the torsion spring and enters into the hook, via the torsion spring, the end of the tongue piece abuts against the inner side of the hook sharp to hold the rope in the hook effectively to realize safety and protection and protect devices or users.
Description
Affiliated technical field
The utility model relates to the anti-slip mechanism of crane hook.
Background technology
At existing crane hook, the anti-slip mechanism of suspension hook is not set, in the course of the work, the rope of Suspended Cargo might cause device damage or personnel casualty accidents from landing on the suspension hook.
The utility model content
The purpose of this utility model is the anti-slip mechanism that crane hook is provided in order to address the above problem, and in the course of the work, the rope of Suspended Cargo can not cause device damage or personnel casualty accidents from landing on the suspension hook.
The technical scheme that its technical matters that solves the utility model adopts is: there is an aperture bar portion inboard at suspension hook, and the direction of aperture is vertical with the plane of suspension hook.Bearing pin of riveted joint is with tongue piece on bearing pin on aperture, and tongue piece can be swung around bearing pin.Torsion spring is installed on bearing pin, and an end of torsion spring leans against the bar portion inboard of suspension hook, and the other end of torsion spring leans against the inboard of tongue piece.Under the effect of torsion spring, the end of tongue piece is against the inboard of suspension hook bill.When the rope of crane hook overcomes the torsion of torsion spring, enter the suspension hook the inside, at this moment, tongue piece is under the effect of torsion spring, and the end of tongue piece is against the inboard of suspension hook bill, makes rope be unlikely slippage in the suspension hook, has played the safety precaution effect.
Effective effect of the present utility model is, uses the anti-slip mechanism of crane hook of the present utility model, and the rope of Suspended Cargo can not cause device damage or personnel casualty accidents from landing on the suspension hook.
Description of drawings
Figure is the structural representation of the anti-slip mechanism of crane hook of the present utility model.1-suspension hook among the figure, 2-tongue piece, 3-bearing pin, 4-suspension hook bar portion, 5--torsion spring.
The specific embodiment
In suspension hook bar portion (4) inboard one aperture is arranged, the direction of aperture is vertical with the plane of suspension hook (1).A riveted joint bearing pin (3) is with tongue piece (2) on bearing pin (3) on aperture, and tongue piece (2) can be swung around bearing pin (3).Torsion spring (5) is installed on bearing pin (3), and an end of torsion spring (5) leans against suspension hook bar portion (4) inboard, and the other end of torsion spring (5) leans against the inboard of tongue piece (2).Under the effect of torsion spring (5), the end of tongue piece (2) is against the inboard of suspension hook (1) bill.When the rope of crane hook overcomes the torsion of torsion spring, enter the suspension hook the inside, at this moment, tongue piece (2) is under the effect of torsion spring (5), and the end of tongue piece (2) is against the inboard of suspension hook bill, and rope is unlikely from the interior slippage of suspension hook (1), has played the safety precaution effect.
Claims (1)
1, the anti-slip mechanism of crane hook, it is characterized in that: there is an aperture bar portion inboard at suspension hook, the direction of aperture is vertical with the plane of suspension hook, bearing pin of riveted joint on aperture, be with tongue piece on bearing pin, torsion spring is installed on bearing pin, an end of torsion spring leans against the bar portion inboard of suspension hook, the other end of torsion spring leans against the inboard of tongue piece, and the end of tongue piece is against the inboard of suspension hook bill.
