Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the utility model. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-2, the anti-drop device for the hoisting mechanism of the safety bridge crane according to the embodiment includes a hanger 1 connected with a hoisting rope, a positive hook 2 and two reverse hooks 3 on two sides of the positive hook 2 are hinged on the hanger 1, and the opening directions of the positive hook 2 and the reverse hooks 3 are opposite; the two lifting hooks in opposite directions are matched to lift a heavy object, the two lifting hooks simultaneously play a supporting role, and the two lifting hooks mutually play an anti-falling role, so that the stability is strong, the trouble that structures such as a spring plate, a buckle and the like need to be replaced periodically is avoided, and the lifting hook is convenient and practical; the two reverse lifting hooks 3 are symmetrically distributed on two sides of the positive lifting hook 2, so that the stress balance at the lifting hook is ensured, the lifting hook is prevented from inclining, and the anti-falling effect is improved;

preferably, the positive lifting hook 2 and the reverse lifting hook 3 are coaxially hinged;

preferably, support tables 4 are arranged on two sides of the positive lifting hook 2 and one side of the reverse lifting hook 3 close to the positive lifting hook 2, after the lifting hook lifts a heavy object, the positive lifting hook 2 and the reverse lifting hook 3 are tightly attached together, and the positive lifting hook 2 and the reverse lifting hook 3 can be supported by the support tables 4, so that the attachment stability between the positive lifting hook 2 and the reverse lifting hook 3 is ensured, and the phenomenon of uneven stress caused by dislocation and slippage is avoided;
