Hydraulic manipulator with adjusting structure for ship maintenance

The hydraulic manipulator with the adjusting structure for ship maintenance comprises a base, a first mechanical arm is hinged to the top of the base, a second mechanical arm is hinged to the top of the first mechanical arm, a rotating arm is hinged to the right end of the second mechanical arm, and meanwhile, a bottom bearing of the rotating arm is connected with a grabbing hand; three through holes are formed in the front side of the fixed box, and the through holes are connected with the three oil conveying pipes correspondingly; a transverse groove is formed in the bottom of the grabbing hand, and grabbing claws are symmetrically connected into the transverse groove. According to the hydraulic manipulator with the adjusting structure for ship maintenance, the abutting rods on the grabhooks can be adaptively adjusted according to the shapes of parts or tools, the contact area of the grabhooks is increased, the stability during grabbing and holding is improved, the joints of the manipulator can be lubricate
