The invention relates to the technical field of supporting devices for ship components, and discloses a supporting device for berthing components, which comprises a
wharf, an embedded plate is embedded in the outer wall of the
wharf, and a movable groove is formed in the outer wall of the embedded plate. According to the supporting device for the berthing component, through the arrangement of a
wharf, an embedded plate, a stress plate, a sliding rod, a positioning hole, a first rotating rod, a second rotating rod, a first spring, a second spring and a limiting ring structure, in the using process of the device, the sliding rod drives a transverse rod to move together in the mode that the stress plate makes contact with a ship body; a spring I is used for counteracting
impact force, and a straight rod is matched with a positioning hole to limit a stress plate, so that the ship body and the stress plate are prevented from continuously and transversely moving to be in contact with a wharf, the influence of stress on a base layer of the wharf is reduced, and the supporting effect of the device on the ship body during berthing can also be guaranteed; and the supporting effect of the device is further improved.
