The invention relates to a safety ladder from a box girder top end to a pier top support, in particular to the field of civil engineering. Up and down reciprocation motion is achieved based on the screw and nut principle, through rotation of a handrail by an operator, a small gear is driven to rotate, the small gear drives a large gear to rotate, the large gear rotates to drive a long screw to rotate, a screw nut connected to the long screw rotates, a pedal plate connected with the screw nut can move up and down along the long screw, the operator can achieve the whole operation process of upper and lower box girders by standing on the pedal plate, the process that for existing design, step up and down climbing layer by layer can be completely replaced, the danger of layer-by-layer climbingcan be effectively avoided, in the whole process, the effect of up and down while stopping is achieved, the operator can achieve the operation process of any corner on the uppers and the lowers of the box girders, the safety guarantee can be improved, and the construction efficiency and the proceed can be promoted.
本发明涉及到一种从箱梁顶端到墩顶支座的安全梯,尤其是土木工程领域,本发明通过丝杠螺母的原理实现上下的往复运动,通过操作人员对扶手的转动,带动小齿轮转动,小齿轮在带动大齿轮转动,大齿轮转动带动长丝杠转动,连接在长丝杠上的丝杠螺母转动,随之与丝杠螺母连接的踩踏板就会沿着长丝杠上下移动,那么操作人员站在踩踏板上就可以实现上下箱梁的整个操作过程,完全替代了由于现有设计的那种一层一层台阶化上下攀爬的过程,有效避免的一层一层攀爬的危险性,并且可以在整个过程中实现随停随上下的效果,有利于操作人员对箱梁的上下任何角落的操作过程,提高了安全保障,促进了施工效率以及进度。
