Anti-falling foundation pit escape ladder
The invention relates to the technical field of civil engineering safety facilities and discloses an anti-falling foundation pit escape ladder. The anti-falling foundation pit escape ladder comprisesa first ladder column, a first crosspiece, a second ladder column and a second crosspiece; a sliding strip is arranged on the first ladder column; a slide groove is formed in the second ladder column;the first ladder column is slidingly connected with the second ladder column; the first crosspiece is fixedly connected with the first ladder column; a connecting piece is arranged at the end part ofthe second crosspiece; the second crosspiece is detachably connected with the second ladder column through the connecting piece; a limiting groove is formed in the front side of the second ladder column; mobile rods and springs are mounted in the connecting piece; limiting holes are uniformly formed in the bottom of the limiting groove; and when the springs are in an extended state, the internalends of the mobile rods are inserted into the limiting holes after penetrating through rear through holes. The anti-falling foundation pit escape ladder has the advantages that the structure is simple; the design is skillful; length adjustment can be realized through sliding connection between the first ladder unit and the second ladder unit so that the anti-falling foundation pit escape ladder can adapt to foundation pits with different depths; and the second crosspiece can be assembled and disassembled to be adjusted through the connecting piece so that the mounting is very convenient.
本发明涉及土木工程安全设施技术领域，公开了防坠落基坑逃生梯，其包括第一梯柱、第一横档、第二梯柱和第二横档，第一梯柱上设置有滑条，第二梯柱上开设有滑槽，第一梯柱与第二梯柱滑动连接，第一横档与第一梯柱固定连接，第二横档的端部设置有连接件，第二横档通过连接件与第二梯柱可拆卸连接，第二梯柱的前侧开设有限位槽，连接件的内部安装有移动杆和弹簧，限位槽的槽底均匀开设有限位孔，当弹簧处于伸展状态时，移动杆的内端穿出后通孔后插接在限位孔内。本发明结构简单，设计巧妙，第一梯子单元和第二梯子单元滑动连接能够实现长度调整，从而能够适应不同深度的基坑使用，且通过连接件可以对第二横档进行拆装调整，安装十分方便。
