The invention discloses a shear type lifting
machine locking
assembly. The
assembly comprises a base, a first
locking mechanism comprises a first resetting spring, an inclined plate and a supporting plate, two ends of the first resetting spring are connected with a lifting
machine and the bottom plate of the inclined plate, a rack is arranged on the inner wall of the bottom end of a shell of a second
locking mechanism, one side of the rack is connected with an adjusting bolt extending to the outer side of the second
locking mechanism, the upper end of the rack is connected with a gear engagedwith the rack, and a limiting block is connected to the top end of the supporting rod. When the lifting
machine ascends, a
pulley rightwards moves in the base, a connecting rod is locked through the limiting block, the phenomenon that due to sliding, the lifting machine falls can be prevented, the structure is simple, the mechanical motion stability is good, under the effect of the first resettingspring, the inclined plate is ejected, the supporting plate is placed in a clamping groove, the secondary fixing effect is achieved, front and back moving of a vehicle is prevented, safety of the lifting machine is improved, and the accident rate is reduced.
