Safety protection mechanism for overhauling and maintaining road bridge pier column
The invention relates to the technical field of roads and bridges, and discloses a safety protection mechanism for road bridge pier stud overhaul and maintenance. The mechanism comprises a bridge pier stud; annular slide rails fixedly sleeve the outer walls of the upper and lower parts of the bridge pier stud, and a ladder stand is arranged between the two annular slide rails; the crawling ladder is formed by combining two parallel handrails and a plurality of pedals distributed at equal intervals, and the left end and the right end of each pedal are fixedly connected to the inner side walls of the two handrails. When hands and feet of an operator press a pedal downwards, the pedal is inserted into an arc-shaped insertion cavity of a handrail through a movable shaft and a semicircular support arm, so that a spring is compressed, and at the moment, a safety clamping arm is moved and rotated by the semicircular support arm; therefore, it is guaranteed that the safety lock head ascends and descends from the gap formed by the safety clamping arm and the handrail. In this way, the problem that an operator needs to move the safety lock body manually without climbing one step and the safety is lower is solved.
本发明涉及道路桥梁技术领域，公开了一种道路桥梁墩柱检修养护用安全防护机构，包括桥梁墩柱，所述桥梁墩柱上下两部外壁均固定套接有环形滑轨，位于两个所述环形滑轨之间设置有爬梯，爬梯有两个相互平行的扶杆和多个等距分布的踏板组合而成，每个所述踏板的左右两端部均固定连接在两个所述扶杆内侧壁。本发明操作人员的手部和脚部对踏板进行向下受压时，踏板通过活动轴以及半圆形支臂在扶杆的弧形插接腔内进行插接，从而对弹簧进行压缩，此时的安全卡臂被半圆形支臂进行移动旋转，从而保证安全锁头从安全卡臂和扶杆形成的间隙进行提升，下降也是这种道理，这种方式无需操作人员没攀爬一步都需要动手将安全锁体移动位置，安全性较低的问题。
