Detailed Description

As shown in fig. 1-3, relate to an anti-disengaging structure of tower crane lifting hook, which comprises a bracket, the inside of support 1 is provided with slide 3, slide 3 bottom fixedly connected with lifting hook 5, the bottom of lifting hook 5 passes the outside that extends to support 1, the surface cover of lifting hook 5 is equipped with compression spring 4, compression spring 4's both ends respectively with slide 3's lower surface, the interior diapire fixed connection of support 1, one side of slide 3 is provided with guide bar 9, one side of guide bar 9 is provided with heterotypic anticreep board 8, wherein compression spring 4's both sides still are provided with a plurality of springs the same rather than the model, make single spring bearing capacity littleer, extension anti-disengaging structure's life.

An opening 2 is formed in one side of the bottom end of a support 1, the bottom end of a special-shaped anti-disengaging plate 8 penetrates through the opening 2 and extends to the outside of the support 1, the bottom end of the special-shaped anti-disengaging plate 8 is separated from or contacts with a lifting hook 5, when an article is lifted and taken, the special-shaped anti-disengaging plate 8 is closed to achieve an anti-disengaging effect, after the lifting and taking are completed, the special-shaped anti-disengaging plate 8 is separated from the lifting hook 5 to facilitate taking off the article, two sides of a guide rod 9 are rotatably connected with two inner side walls of the support 1 through second rotating pins 11, two sides of the special-shaped anti-disengaging plate 8 are rotatably connected with two inner side walls of the support 1 through first rotating pins 10, one end of the guide rod 9 is contacted with a sliding plate 3, the other end of the guide rod 9 is contacted with the special-shaped anti-disengaging plate 8 to facilitate adjusting the direction of the special-shaped anti-disengaging plate 8 through rotation of the guide rod 9, a jacking spring 7 is arranged at one end, which the special-disengaging plate 8 is contacted with the guide rod 9, the one end of shoring spring 7 is fixed with the interior roof of support 1, and the other end of shoring spring 7 is fixed with heterotypic anticreep board 8, can shoring heterotypic anticreep board 8 under the effect of the restoring force of shoring spring 7 for heterotypic anticreep board 8 breaks away from the article that will hang and get with lifting hook 5 and takes off, and the inside fixedly connected with slide bar 6 of support 1, slide 3 cover are established at the surface of slide bar 6, have improved the stability that slide 3 removed.
