Zusammenfassung:	The utility model belongs to the technical field of mechanical transmission, and provides a hydraulic cylinder two-stage locking device under large load capacity, which comprises a locked hydraulic cylinder, a locking hydraulic cylinder, a piston rod sleeve, a sliding block, a piston rod head and the like. The piston rod sleeve is installed on the end face of the locked hydraulic cylinder, the supporting frame is installed on the piston rod sleeve, and the locking hydraulic cylinder is installed on the supporting frame. A piston rod of the locking hydraulic cylinder is connected with the sliding block through a piston rod head. A sliding way is arranged on the piston rod sleeve, the size of the sliding way is matched with that of the sliding block, the sliding block is guided, and the sliding block is installed on the sliding way of the piston rod sleeve. According to the two-stage locking device of the hydraulic cylinder, through the two-stage locking process, the locking action under the large external load
