Lifting and feeding mechanism of hook core quenching production line

The utility model discloses a lifting and feeding mechanism for a shank quenching production line, which comprises a transport trolley and a lifting platform embedded below the ground of a plant, and a limiting side plate higher than the upper surface of a bearing platform is arranged on one side edge of the bearing platform of the lifting platform. A positioning component for the transport trolley to pass through is arranged at the central position, close to the bearing platform, of the limiting side plate on the upper surface of the bearing platform, and a positioning area for limiting movement of the transport trolley is formed between the positioning component and the limiting side plate. The utility model has the following advantages and effects: the distance between the feeding mechanism of the quenching production line and the ground is compensated in a mechanical manner, so that the stooping action of a worker in the carrying process is reduced, the body health of the worker is ensured, and the quench
