The invention relates to a high-strength three-layer telescopic pallet fork mechanism. The technical problems that an existing conventional pallet fork mechanism is complex in structure and low in fork discharging speed, has multiple faults and difficulty in maintenance and is poor in rigidity are mainly solved. According to the technical scheme, the high-strength three-layer telescopic pallet fork mechanism comprises a bottom plate, two three-layer sliding pallet forks and a driving mechanism, the two three-layer sliding pallet forks are installed on the two sides of the bottom plate correspondingly, the driving mechanism is arranged in the middle of the bottom plate, and the two ends of a connecting rod in the driving mechanism are connected with the front ends of the middles of the outer surfaces of the inner sides of upper forks in the three-layer sliding pallet forks. The driving mechanism comprises a linear motor, a motor, a second-stage outer tooth internal thread wheel, a first-stage outer tooth internal thread wheel, a driving wheel, a second-stage lead screw, a first-stage lead screw, a connecting rod, a motor sliding support, a lead screw protection pipe, a protection pipe rear support, a protection pipe front support and a support. The high-strength three-layer telescopic pallet fork mechanism has the advantages of being simple in structure, convenient to install and maintain, high in synchronous fork discharging efficiency, capable of achieving multi-direction fork stretching and retracting when placed on a rotating table and the like.
