Technical Field

[0001] The utility model relates to the technical field of lift anti-collision, in particular to a novel steel rolling rotary lift anti-collision device. Background Art

[0002] In the production of modern steel enterprises, the steel coils coming out of the rolling mill are moved to the conveyor roller by the rotary lift. When the rotary lift rotates upward 90 degrees, the rotary lift cooperates with the conveyor roller. Starting the roller motor can transfer the steel coils from the rotary lift to the conveyor roller. During the return process, the rotary lift descends quickly. The impact force generated by the collision between the rotary lift and the platform below will damage the equipment of the rotary lift and reduce the service life of the rotary lift. Some existing steel enterprises have set an anti-collision device with a leather pad fixedly connected to a steel plate on the rotary lift to avoid direct collision between the rotary lift and the platform. After the rotary lift returns from the end of the conveyor roller, it directly hits the anti-collision device. The leather pad on the anti-collision device can partially alleviate the impact force of the rotary billet transfer car.

[0003] However, in the anti-collision structure currently used in lifts, the leather pad is directly subjected to the impact and is also baked by the high temperature in the working environment, which will easily cause damage and aging, and thus shorten its service life. Utility Model Content

[0007] Preferably, one end of the first limit spring is welded to the circular baffle, and the other end of the first limit spring is welded to the fixing sleeve.

[0008] Preferably, one end of the long screw passes through the middle of the fixed connecting plate, and the fixing nut contacts a position of an end surface of the fixed connecting plate away from the fixing sleeve;

[0009] One end of the fixed connecting plate is welded to the rotary lift base.

[0010] Preferably, the fixing through hole is opened at a position on the outside of the outer sleeve corresponding to the long screw hole, and the fixing bolt passes through the middle of the fixing through hole.

[0014] 1. By arranging a long screw, a fixing nut, a round baffle, a first limit spring, an outer sleeve, a metal sleeve, an elastic block, a moving groove and a second limit spring, when the lift moves downward from a lifting state, the metal sleeve and the elastic block inside it will be squeezed first to perform preliminary buffering, and then the round baffle and the long screw will continue to be squeezed to squeeze the first limit spring to contract. At the same time, the long screw moves inside the fixed connecting plate, and the second limit spring inside the moving groove will be squeezed toward the position of the positioning plate as the long screw moves, and buffering is performed again. After double buffering, the impact is better dispersed, so that the lifting mechanism of the lift can be smoothly lowered without causing a large impact with the base of the lift, making the lift more stable to use and not easy to be damaged, thereby extending the service life of the lift and the anti-collision structure.
