Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 to 4, the utility model provides an anti-unhooking device applied between a hanger hook and a grab bucket, which comprises a grab bucket and two connecting ear plates 1 fixedly connected on the grab bucket, wherein the two connecting ear plates 1 are both provided with a through mounting hole 101, a connecting shaft 2 for hooking the hanger hook is arranged in the mounting hole 101, and an anti-unhooking shell 3 is rotatably arranged on the connecting shaft 2 between the two connecting ear plates 1; the anti-disengaging shell 3 and the circumferential surface of the connecting shaft 2 enclose a limiting cavity channel 4 for limiting a hanger hook; when the hanger hook is hung on the connecting shaft 2, the hanger hook is limited in the limiting cavity channel 4 by rotating the anti-falling clamp shell 3, so that the lifting steel wire rope of the crane can be ensured not to incline and slip after being released, and the effect of safe limitation is achieved.

Wherein, anticreep card shell 3 includes two rotor plates 31 that are parallel and be fan-shaped structure, and the lower extreme rigid coupling of two rotor plates 31 has cambered plate 32, has seted up concentric rotation hole 33 on two rotor plates 31, installs whole anticreep card shell 3 back on connecting axle 2 through rotating hole 33, can realize the rotation of anticreep card shell 3, is convenient for let cambered plate 32 can form good laminating state with the hoist couple after rotating, forms stable spacing to the hoist couple.

In the hoisting process, the stable installation of the connecting shaft 2 is ensured, the connecting shaft 2 comprises a shaft body 30, one end of the shaft body 30 is fixedly connected with a limiting plate 37, the other end of the shaft body 30 is provided with a limiting groove 36, and an anti-falling clamping plate 34 is arranged in the limiting groove 36; after the shaft body 30 penetrates through the two connecting ear plates 1, the position of the shaft body 30 is limited through the action of the limiting plate 37, and meanwhile, the shaft body 30 is limited through the clamping action between the anti-falling clamping plate 34 and the limiting groove 36; in order to further ensure that the position of the anti-falling clamping plate 34 does not change, the shaft body 30 is provided with an external thread structure 35 at the rear end of the limiting groove 36, and the external thread structure 35 is rotatably sleeved with a locking nut, so that the anti-falling clamping plate 34 is more stable when the whole connecting shaft 2 is mounted on the two connecting lug plates 1 under the action of the locking nut.

Simultaneously for the ease of installation or dismantle anticreep cardboard 34, let anticreep cardboard 34's shape be "C" shape structure to let anticreep cardboard 34's internal diameter be less than the tank bottom diameter of spacing groove 36, so that let anticreep cardboard 34 can the chucking.
