A feeding cylinder lifting device for a secondary feeding device

Abstract

The application relates to a feeding cylinder lifting device for a secondary feeding device, which comprises a lifting beam and a plurality of lifting hooks arranged at the lower end of the lifting beam, the lifting hook comprises a hook handle, a hook bend and a hook tip, a hook opening is formed between the hook handle and the hook tip, a lifting ring is arranged at the upper end of the lifting beam, an anti-unhooking piece is arranged on the lifting hook, the anti-unhooking piece comprises a locking rod hingedly arranged on the hook handle, a limiting protruding part capable of abutting against the locking rod is arranged on the hook tip, an auxiliary rod is arranged at the rear end of the locking rod, a plurality of auxiliary rods are connected through a counterweight rod, the locking rod can abut against the limiting protruding part under the gravity of the counterweight rod, so as to realize the locking rod closing the hook opening. The counterweight rod naturally falls under the gravity, linkage is realized through the auxiliary rod, the locking rod is forced to rotate around the hinge point, the front end of the locking rod is automatically abutted against the limiting protruding part on the hook tip, rigid blocking is formed, the locking rod can automatically close the hook opening, unhooking is effectively realized, and operation safety is ensured.
