The invention discloses an improved crane for ship maintenance. The improved crane comprises a machine frame, wherein two frame openings are formed in the side wall of the machine frame, clamping mechanisms for clamping a ship are arranged in the frame openings, each clamping mechanism comprises a sliding plate slidably connected to the inner wall of the corresponding frame opening, and a T-shaped column is fixedly connected to the lower ends of the sliding plates; and the two ends of the T-shaped column are rotationally connected with two first connecting mechanisms, each first connecting mechanism is composed of two first connecting rods, and the side walls of the two first connecting mechanisms are rotationally connected with two second connecting mechanisms through rotating shafts. According to the improved crane, by arranging the clamping mechanism, a motor rotates to drive the sliding plates to slide upwards, two clamping plates get close to each other, and the ship is clamped, so that the situations that the ship shakes in the hoisting process, the ship and the crane are damaged due to the fact that the ship collides with the crane easily, and surrounding maintenance personnel are damaged easily, and in the maintenance process, the maintenance progress is influenced by the shaking of the ship, and the working efficiency is reduced are avoided.
本发明公开了一种改进型船舶维修用起重机,包括机架,所述机架侧壁开设有两个框口,所述框口内设有对船舶进行夹持的夹持机构,所述夹持机构包括滑动连接在框口内壁的滑板,所述滑板下端固定连接有T型柱,所述T型柱两端转动连接有两个第一连接机构,两个所述第一连接机构均由两个第一连杆组成,两个所述第一连接机构侧壁均通过转轴转动连接有两个第二连接机构。本发明通过设置夹持机构,电机转动带动滑板上滑使得两个夹板相互靠近,从而对船舶进行夹持,避免船舶被吊起过程中晃动,使得船舶不仅容易与起重机碰撞,导致船舶和起重机损坏,还容易对周围维修人员造成伤害,并且在维修过程中,船舶的晃动还会影响维修进度,降低工作效率。
