Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Bayonet lifting hook anticreep device, as shown in figure 1 and figure 2, including couple 1, couple 1 a side surface top fixedly connected with hollow steel pipe 2, the inboard fixedly connected with at the prong position of couple 1 extends to the arc gag lever post 3 at 1 prong position one side of couple, arc gag lever post 3 can adopt the reinforcing bar to fix at the prong position of couple 1 through the welded mode, hollow steel pipe 2's inside alternates has conflict kelly 4 in 3 bottoms of arc gag lever posts, kelly 4 can adopt the diameter to be greater than the reinforcing bar of 2 internal diameters of hollow steel pipe, and kelly 4 is close to the handle 5 that hollow steel pipe 2's one end fixedly connected with was used for preventing kelly 4 and drops, can utilize handle 5 to carry out the plug to kelly 4, and block kelly 4 through handle 5, make handle 5 support and keep off on hollow steel pipe 2's top, avoid kelly 4 to drop.

As shown in attached drawings 1 and 2, the hollow steel pipe 2 is obliquely arranged at the top of the side face of the hook 1, and the hollow steel pipe 2 and the arc-shaped limiting rod 3 are arranged in parallel, so that the clamping rod 4 can be conveniently clamped with the arc-shaped limiting rod 3 after being inserted into the hollow steel pipe 2.

As shown in fig. 1 and 2, one end of the arc-shaped limiting rod 3 is fixedly connected to the inner side of the hook tip of the hook 1, and the other end of the arc-shaped limiting rod 3 is fixedly connected to one side of the hook tip of the hook 1, so that the end of the arc-shaped limiting rod 3 extending to one side of the hook tip of the hook 1 can be clamped with the clamping rod 4.

As shown in fig. 1 and 2, two pulleys 6 are fixedly connected to the top of the hook 1, and a lifting rope 7 is wound inside the two pulleys 6, so that the hook 1 can be suspended by the pulleys 6 and the lifting rope 7.

As shown in fig. 1 and 2, a lifting appliance 8 is suspended in the hook 1, and the lifting appliance 8 is located below the clamping rod 4, so that the lifting appliance 8 can be suspended on the hook 1, and meanwhile, the lifting appliance 8 is blocked by clamping between the clamping rod 4 and the arc-shaped limiting rod 3, and the lifting appliance 8 is prevented from falling off.
