Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example.

Referring to Figures 1-3, this solution provides an embodiment: a safe and reliable bridge crane, including:

The bridge crane body 1 and the hook 1, the hook 2 are fixed on the bridge crane body 1;

Therefore, the anti-off U-shaped bar 4 is rotatably provided on the hook 2. Side bars 9 are slidingly provided on both sides of the anti-off U-shaped bar 4. Both side bars 9 are fixedly provided with plug-in shafts 12. The two plug-in shafts 12 are all plugged into the hook 2.

Referring to Figure 2, in this embodiment, the hook 2 is fixed with a clamping shaft 3, and the anti-falling U-shaped strip 4 is rotatably connected to the clamping shaft 3, so that the anti-loosing U-shaped strip 4 can be conveniently rotated on the hook 2.

Referring to Figure 2, in this embodiment, two L-shaped openings 5 are provided on the anti-falling U-shaped bar 4, and L-shaped rods 6 are slidably provided in the two L-shaped openings 5. Both ends of the two L-shaped rods 6 Both extend to the outside of the anti-falling U-shaped bar 4, and the two L-shaped rods 6 are fixedly connected to the corresponding side bars 9. One end of the two L-shaped rods 6 is fixedly provided with a push block 7, and the two push blocks 7 are fixedly connected to each other. Both sides are fixedly provided with anti-slip strips 8, which can facilitate the movement of the two side strips 9 away from each other.

Referring to Figure 2, in this embodiment, the limit rods 10 are fixedly installed on both sides of the anti-falling U-shaped bar 4, and the two side bars 9 are slidably sleeved on the outside of the corresponding limit rods 10, so that the two side bars can be Strip 9 plays a limiting role.

Referring to Figure 2, in this embodiment, the two side bars 9 are fixedly provided with return springs 11, and the two return springs 11 are fixedly provided on the anti-falling U-shaped bar 4, which can facilitate the return movement of the two side bars 9. .

Referring to FIG. 3 , in this embodiment, the hook 2 is provided with an insertion hole 13 , and both insertion shafts 12 are inserted into the insertion holes 13 , so that the two insertion shafts 12 can be inserted into the hook 2 conveniently.

The working principle is that when lifting heavy objects, you can first push the two push blocks 7 so that they can drive the two side bars 9 to move away from each other through the two L-shaped rods 6, and stretch the return spring 11, so that The two side bars 9 can drive the two plug shafts 12 to slide out of the sockets 13 opened on the hook 2. Then, the anti-off U-shaped bar 4 can be rotated, and then the heavy object can be hung on the hook 2, and then rotated. Return to the U-shaped strip 4 to prevent the removal, and release the two push blocks 7. Through the elastic deformation of the two return springs 11, the two side strips 9 can be moved closer to each other and reset, and drive the two insertion shafts 12 to reset. , so that the two insertion shafts 12 can slide into the insertion holes 13 provided on the hook 2, which can prevent the heavy objects from slipping during hoisting.
