please refer to fig. 4, which is a schematic diagram of a fourth stage working state of the novel stepping cooling bed 1. Finally, the first walking hydraulic cylinder 40 and the second walking hydraulic cylinder 42 are both retracted, the equipment returns to the initial state, namely, a movement cycle is completed, the movement is repeated, the billet 45 on the stepping cooling bed can be turned over and moved forwards, and the driving energy can be saved.

Therefore, the novel stepping cooling bed 1 adopts a positive and negative parallel four-bar structure as a driving structure, so that the overall structural layout is reasonable, the operation principle is simple, the manufacturing cost can be effectively reduced, and the use can be saved; the operation is convenient in a plurality of aspects of equipment installation, debugging, use, maintenance and the like, the driving energy can be effectively saved, and the use and maintenance cost is reduced; the longer the length of the stepping cooling bed in the structure is, the more obvious advantages of the structure can be embodied, and the efficiency of conveying the steel billet 45 can be effectively improved; the whole stepping cooling bed can also increase the number of cooling bed sections according to production requirements, and has wide application range.
