Compared with prior art, the advantageous effect of the major-minor hook limiting device of double girder crane provided by the utility model It is：The utility model is utilized replaces traditional weight through the horizontal steel plate of main hook and auxiliary hook both sides steel wire rope, makes connection steel Silk is detached with the steel wire rope of main hook and auxiliary hook, avoids the security risk of the winding initiation of connection steel wire and steel wire rope, structure letter Single, significant effect, eliminates security risk.

Description of the drawings

It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Other attached drawings are obtained, wherein：

Fig. 1 is the structural schematic diagram of the major-minor hook limiting device of double girder crane provided by the utility model；

Fig. 2 is the structural schematic diagram of the major-minor hook limiting device of existing double girder crane.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The all other embodiment obtained, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the major-minor hook limiting device 1 of the double girder crane includes 11 He of main hook set on trolley 10 Auxiliary hook 12 and for main hook 11 and auxiliary hook 12 limit limiting device, the limiting device includes main hook limiter 13, auxiliary hook Limiter 14, steel plate 15, connection steel wire 16, steel pipe 17, the steel pipe 17 are vertically welded in the bottom plate of trolley 10, and described Steel pipe 17 is between the main hook 11 and auxiliary hook 12, and the steel plate 15 includes two, and one is horizontally through 11 liang of the main hook The steel wire rope of side, one end are connect by connecting steel wire 16 with main hook limiter 13, and the other end is fixed on the steel pipe 17, another A steel wire rope for being horizontally through 12 both sides of the auxiliary hook, one end is connect by connecting steel wire 16 with auxiliary hook limiter 14, another The steel pipe 17 is fixed at end, and the main hook limiter 13 and auxiliary hook limiter 14 are set to the bottom plate of trolley 10.
