The shield tunneling machine body anti-skid steel plate step comprises a steel plate body, steel rhombic nets and inclined grooves, the multiple steel rhombic nets are arranged in the steel plate body, multiple threaded grooves are formed in the side, away from the steel rhombic nets, of the steel plate body, and fixing blocks are arranged in the threaded grooves; a spherical groove is formed in the fixing block, an inclined groove is formed in the top end of the spherical groove, an inclined block matched with the interior of the inclined groove is installed in the inclined groove, an arc-shaped stopping block is installed at the top end of the inclined block, and a plurality of arc-shaped positioning blocks are arranged on the two sides of the steel plate body; the outer wall of the arc-shaped positioning block is sleeved with a movable frame matched with the outer wall of the steel plate body, and a friction block is arranged on the outer wall of the movable frame. By the adoption of the technical scheme, the arc-shaped limiting blocks are driven to be inserted into the arc-shaped positioning blocks under the action of elastic force of the springs, and the length of the steel plate body is conveniently increased.
本发明公开了一种盾构机机体防滑钢板台阶,包括钢板本体、钢制菱形网和倾斜槽,所述钢板本体的内部设置有多个钢制菱形网,所述钢板本体远离钢制菱形网的一侧开设有多个螺纹槽,且螺纹槽的内部设置有固定块,所述固定块的内部开设有球形槽,且球形槽的顶端开设有倾斜槽,所述倾斜槽内部安装有与倾斜槽内部相匹配的倾斜块,且倾斜块的顶端安装有弧形阻挡块,所述钢板本体的两侧开设有多个弧形定位块,所述弧形定位块外壁套设有与钢板本体外壁相匹配的移动框架,且移动框架的外壁设置有摩擦块;采用本技术方案,通过在弹簧自身弹力作用下带动弧形限位块插入弧形定位块内,便于延长钢板本体的长度。
