Specifically, the anti-falling hoisting clamp provided by the embodiment relatively mounts the eccentric clamping pieces on the hoisting frame 1 at preset intervals, so that when the relatively mounted eccentric clamping pieces are driven by the driving part to eccentrically swing close to each other, clamping of a hoisted object can be realized, and correspondingly, when the relatively spaced eccentric clamping pieces are eccentrically swung far away from each other, release of the hoisted object can be realized. Because the clamping end of the eccentric clamping piece is positioned at the upper side of the rotating center of the eccentric clamping piece, when the eccentric clamping piece which is relatively separately assembled swings eccentrically and approaches, the corresponding clamping end of the eccentric clamping piece can do eccentric motion from top to bottom and gradually approach until the clamping of a hoisted object is achieved, when the hoisted object is hoisted, the hoisted object has a tendency of descending motion under the action of the dead weight of the hoisted object, at the moment, the corresponding clamping end of the eccentric clamping piece generates vertical downward contact friction force which drives the eccentric clamping piece to continuously swing eccentrically and approach, so that larger clamping force is generated on the hoisted object, the contact friction force between the hoisted object and the clamping end of the eccentric clamping piece is correspondingly increased, the larger gravity of the hoisted object is formed, the larger tendency of the eccentric clamping piece to swing and approach is formed, and the larger clamping force is generated on the hoisted object, so guaranteed to implement effectual centre gripping to hoist and mount thing, prevented that hoist and mount thing from taking place the risk that drops at the in-process of hoist and mount.
It should be noted that the eccentric clamping member may be an eccentric wheel, an eccentric roller, an eccentric block, or the like capable of realizing eccentric oscillation, which is well known in the art, and is not particularly limited thereto.
