The invention discloses a hydraulic locating pile lifting device with a good working performance. The device comprises an upper ring beam and a lower ring beam, wherein a lifting cylinder is arranged between the upper ring beam and the lower ring beam and connected with the upper ring beam and the lower ring beam through cylinder hinge shafts; bolts are matched with bolt holes formed in a locating pile; through a hinge, the lower ring beam is connected with a hinge seat, which is firmly welded on a deck; a self-lubricating spherical plain bearings are mounted in an upper hinging point and a lower hinging point of the hinge so that the hinge can swing to compensate inbalance caused by factors such as inclination of the locating pile, the deformation of a ship body and the like; and as the bolt on the lower ring beam is a supporting bolt and the bolt on the upper ring beam is a working bolt, one of the bolts on the upper ring beam and the lower ring beam must be always kept in the bolt hole to assure the safety during operation. The hydraulic locating pile lifting device with the good working performance, disclosed by the invention, has the advantages of reasonable structure and good working performance. The bolts on the upper ring beam and the lower ring beam are alternately inserted into the bolt holes in the locating pile and a piston rod of a hydraulic cylinder extends and retracts so as to lift and lower the locating pile; and meanwhile, the ship body is lifted and lowered.
