Further, an air pump 51 is installed on the hanging beam 5; the air pump 51 is connected to each of the left suction cup 69 and the right suction cup 610 through the pipeline 52, so as to pump out the air in the left suction cup 69 and the right suction cup 610, so that the air in the rubber suction cup 693 is exhausted to generate negative pressure, and the effect of adsorbing the square pile 100 is achieved. Of course, the air in the rubber suction cup 693 can be extruded, so that the air is discharged from the suction cup, the air pressure in the suction cup is far smaller than the external air pressure, and the effect of adsorbing the square pile 100 can be achieved.
The anti-shaking device 7 is connected between the lifting trolley 4 and the lifting beam 5, can prevent the lifting beam from shaking, ensures lifting safety and improves lifting efficiency. The anti-shake device 7 includes a hinge rod I71, a hinge II72, and a connection shaft 73; wherein the top end of the hinge rod I71 is hinged to the lifting trolley 4; the connecting shaft 73 is connected with the hinge rod I71 and the hinge II72, so that the hinge rod I71 and the hinge II73 can rotate relatively to fold; the bottom end of the hinge II72 is hinged to the hanging beam 5.
The working principle of the square pile vacuum chuck bridge crane is as follows:
1. the bridge frame 1 is driven to walk through the bridge frame running mechanism 3, so that the sucker device 6 is positioned above the square pile 100.
2. The lifting trolley 4 drives the hanging beam 5 to descend so that the left sucker 69, the right sucker 610 and the square pile 100 of the sucker device 6 are in contact.
3. The left sucker 69 and the right sucker 610 sequentially push the guide joint 66 and the upright post 65, so that the upright post 65 moves upwards; at this time, the spring I64 is compressed and the spring II67 is extended, so that the impact force among the left sucker 69, the right sucker 610 and the square pile 100 can be absorbed, and the crane is not easy to damage; meanwhile, the air in the left sucking disc 69 and the right sucking disc 610 is discharged, so that the air pressure in the sucking disc is far smaller than the external air pressure, and the purpose of sucking the square pile 100 is achieved.
4. The lifting trolley 4 drives the hanging beam 5 to ascend, and the hanging beam 5 and the square pile 100 are prevented from shaking by the anti-shaking device 7;
5. the bridge frame 1 is driven to walk through the bridge frame running mechanism 3, so that the purpose of transferring square piles 100 is achieved.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the scope of the present invention.
