Description

Marine elastic linkage suspension arm shelving device Technical Field The utility model belongs to the technical field of marine electric supply cranes, and particularly relates to a device for placing a marine elastic linkage suspension arm. Background The traditional suspension arm shelving device is mainly fixed by adopting rigid buckles or manual binding, and has the obvious defects that the rigid buckles are matched according to preset sizes, are difficult to adapt to suspension arms with different diameters, are easy to generate stress concentration due to rigid contact when a ship jolts, lead to structural fatigue, have low efficiency, are greatly influenced by experience of operators, and are easy to cause safety accidents due to unstable fixation. Disclosure of Invention The utility model aims to overcome the defects in the prior art, and provides the ship elastic linkage suspension arm shelving device which realizes the adaptive clamping of the suspension arm through mechanical linkage and an elastic suspension structure and improves the shelving stability of the suspension arm. The technical scheme is that the ship elastic linkage suspension arm shelving device comprises a suspension arm shelf with an expansion type shelving groove at the top, wherein a lower pillow is arranged at the bottom of an inner groove of the expansion type shelving groove, side pillows which are bilaterally symmetrical are arranged on the wall of the inner inclined groove in a sliding manner, a traction rope is connected between the side pillows and the lower pillow, and an elastic hanging piece is hung on the side pillow; The lifting force provided by the lower pillow through the elastic hanging piece is larger than the self weight of the lower pillow, and the lower pillow keeps a distance from the bottom of the inner groove in a normal state; When the suspension arm is placed, the lower pillow moves downwards by overcoming the lifting force, and the side pillow is driven to incline and slide downwards to clamp the suspension arm by pulling the pull rope to apply a tension component to the side pillow in the direction of the central line of the suspension arm.
