Novel anti-overturning and anti-rollover safety ladder for climbing up and down box girders
The invention relates to the technical field of civil engineering. The invention relates to a novel anti-overturning and anti-rollover safety ladder for climbing up and down box girders, and particularly aims at the using problem of safety ladders in construction sites in the field of civil engineering. Adjustable inclined supporting upper columns are added on two sides of an ordinary ladder so asto better improve the safety of the ladder and more stabilize the safety of the ladder. Bolts connected to lower columns are in cooperative connection with nuts fixedly arranged at the inner walls ofthe upper columns, and the lower columns can be rotated to achieve length adjustment along the direction of the lower columns so as to support the ladder when the length is affected by angle variation in different situations. The upper columns can be changed at any angle to achieve supporting through the self-rotation adjustment of rotating shafts, and at the same time, serrated antiskid teeth are designed at positions where the lower columns and a ladder body are in contact with the ground, so that the problem of on-site skid resistance is better solved.
本发明涉及土木工程技术领域，本发明涉及到一种新型上下箱梁的防倾覆侧翻的安全梯，尤其是土木工程领域针对施工现场的安全梯的使用问题，通过对普通梯子两侧增加可调节的斜支撑上柱子，以便更好的增加梯子本身的安全性，以便更加稳固梯子的安全性，下柱子连接的螺杆与上柱子内壁固定设置的螺母配合连接，可以转动下柱子使其下柱子沿着自身方向有一个长度的调节，以便对梯子适用于不同场合角度变化而影响长度的支撑，通过转轴的自身转动调节使其上柱子可以任意角度的变化支撑，同时在下柱子以及梯身本身与地面接触的部分设计有锯齿形防滑齿，以便更好的解决现场的防滑问题。
