The invention relates to the technical field of cable laying ships, in particular to a large-angle pitching cable laying portal frame which comprises a portal frame with a transverse moving roller, and the bottom of a stand column on the portal frame is coaxially hinged to a base. A variable-amplitude oil cylinder is arranged on the transverse outer side of the stand column; the hinge points of the upper ends of the two variable-amplitude oil cylinders and the stand column are located in the same transverse direction, and the hinge points of the lower ends of the two variable-amplitude oil cylinders and the base are staggered in the longitudinal direction; when one variable-amplitude oil cylinder reaches the dead point position, the other variable-amplitude oil cylinder can continuously drive the portal frame to move, so that the overall variable-amplitude angle of the portal frame is effectively increased, the maximum variable-amplitude angle can reach 150 degrees, meanwhile, the overall structure is simple, the manufacturing cost is reduced, and the variable-amplitude oil cylinder is suitable for cable laying ship cable collecting and releasing equipment and other heavy equipment devices.
本发明涉及铺缆船技术领域,特别涉及一种大角度俯仰铺缆门架,包括带有横移滚筒的龙门架,该龙门架上的立柱底部同轴铰接在底座上;立柱沿横向的外侧设有变幅油缸;两个变幅油缸的上端与立柱的铰接点处于同一横向上,两个变幅油缸的下端与底座的铰接点沿纵向相互错开;当其中一个变幅油缸到达死点位置时,另一个变幅油缸能够继续带动龙门架运动,从而有效提高龙门架整体的变幅角度,最大变幅角度可达到150°,同时,整体结构简单,降低了制造成本,适用于铺缆船收放铺缆设备以及其他重型设备装置。
