Description

Chain transmission unit for cooling bed steel arranging machine Technical Field The utility model relates to the technical field of large-scale bar conveying and transferring equipment, in particular to a chain transmission unit for a cooling bed steel arranging machine. Background In a steel production workshop, after related rolling, forging and other processes, the large-sized steel bar workpieces are transported to the next process station for operation in a direct transfer mode generally not easy due to the large size of the workpieces, so that large-area cooling beds are used for conveying, the structure of the conveying cooling bed is designed, a chain bracket is designed, large-sized transmission chains are adopted, and the circulation operation of a plurality of groups of transmission chains which are arranged in parallel is realized, the steel bar is supported to be transmitted forwards, but the conventional transmission chain structure on the cooling bed is in a loose or use fatigue state due to the fact that the tensioning mechanism is loose or is used for fatigue along with the use time, meanwhile, the transmission chain is relatively long, the transmission chain is easy to naturally loose and fall down, when the chain is loose, the steel bar entering the cooling bed steel arranging machine always turns and does not walk, and the transmission efficiency of the steel bar is seriously affected. Meanwhile, the tensioning adjustment of the transmission chain on the cooling bed steel arranging machine is basically in a rigid adjustment mode, and manual operation is often required for adjustment, so that the condition of adjusting the transmission chain in real time cannot be achieved, and the production is affected.
