The invention relates to a track energy storage hydraulic tensioning device and a paver. The tensioning device comprises a hydraulic cylinder body and an oil cylinder piston rod, a transition body with a central through hole is arranged in the middle of the hydraulic cylinder body, an inner cavity of the hydraulic cylinder body is divided into two cavities, one cavity is located on the cylinder cover side of the hydraulic cylinder body, and the other cavity is located on the opening side of the hydraulic cylinder body and used for allowing a piston rod of the oil cylinder to stretch out and draw back. An isolation piston is embedded in the cylinder cover cavity in a sliding mode, and the cylinder cover cavity is divided into an air cavity and an oil cavity. An inflation valve and a hydraulic joint are arranged on the hydraulic cylinder body and are respectively connected with the air chamber and the oil chamber; the spreading machine is provided with the tensioning device. The device is simple in structure, high in reliability, easy to maintain and low in cost, and the stability, reliability and safety of the crawler walking system are improved.
