The invention belongs to the technical field of shipbuilding, and discloses a novel spiral staircase protective cover which comprises a central column, a spiral staircase, a groove-shaped wall and a protective cover body, the protective cover body comprises a main steel pipe, a reinforcing steel pipe and a base plate, and the main steel pipe is bent according to the shape of the spiral staircase;after bending manufacturing of the main steel pipe is completed, the main steel pipe is fixedly placed in parallel, reinforcing steel pipes are welded, the reinforcing steel pipes should be evenly arranged, and stress balance is guaranteed; after manufacturing of the protective cover is completed, matching is carried out by using tooling, the protective cover is lifted, installation of the protective cover can be completed by welding the base plate to the groove-shaped wall. The invention aims to provide the protective cover for the spiral staircase, which is only arranged at the position of the spiral staircase protruding out of the cargo hold groove-shaped wall, namely the spiral staircase structure, and the position with extrusion risk of personnel, not only can be well matched with thespiral staircase, but also greatly reduces the weight of an empty ship, and has the advantages of simple design, convenience in use, good universality and the like.

    本发明属于船舶制造技术领域,公开了一种新型盘梯保护罩,其包括:中心柱、盘梯、槽型壁和保护罩本体,其中保护罩本体包括主钢管、加强钢管和垫板,根据盘梯造型,对主钢管进行弯曲制作;完成主钢管弯曲制作后,将主钢管平行固定放置,焊接加强钢管,注意加强钢管应均匀布置,保证受力均衡;完成保护罩的制作后,使用工装进行配合,将保护罩吊起,通过垫板焊接于槽型壁处即可完成保护罩的安装,本发明的目的是提供一种用于盘梯的保护罩,仅在盘梯突出货舱槽型壁处,即盘梯结构、人员存在受挤压风险处安装,既能与盘梯良好地配合,又大大减轻了空船重量,具有设计简单,使用方便,通用性好等优点。
