Combined safety protection structure for urban municipal engineering construction

NAKA HAKYO / QIAN LIQUN

The invention relates to the field of municipal engineering construction, in particular to a combined safety protection structure for urban municipal engineering construction, a mounting groove is formed in the ground, the combined safety protection structure comprises a baffle and a mounting shell, and the baffle and the mounting shell are both located in the mounting groove; the baffle is closer to the ground than the mounting shell and higher than the mounting groove, the bottom end of the baffle is located in the mounting shell, a height adjusting mechanism and a rotating mechanism are arranged in the mounting shell, the rotating mechanism is rotationally connected with the baffle, and the rotating mechanism is used for rotating the baffle to be staggered with the mounting groove; the height adjusting structure is used for driving the baffle to lift; a plurality of pulleys and sliding rods are rotationally mounted on the baffle, and mounting clamping grooves for mounting the pulleys and the sliding rods are formed in the baffle; and when the baffle rises until the bottom end of the baffle is higher than the ground, the pulley can rotate to abut against the ground through the sliding rod, and the pulley can also rotate into the mounting clamping groove. The device has the effect of improving the operation efficiency.

本申请涉及市政工程建设的领域，尤其是涉及一种城市市政工程建设施工用组合式安全防护结构，地面上开设有安装凹槽，其包括挡板和安装壳，挡板和安装壳均位于安装凹槽内，挡板相较于安装壳靠近地面且挡板的高度高于安装凹槽的高度，挡板的底端位于安装壳内,安装壳内设置有高度调节机构和转动机构，转动机构与挡板转动相连,转动机构用于将挡板转动至与安装凹槽交错设置；高度调节结构用于驱动挡板升降；挡板上转动安装有多个滑轮和滑杆，挡板上开设有供滑轮和滑杆安装的安装卡槽；当挡板升高至挡板的底端高于地面时,滑轮可通过滑杆转动至与地面相抵接，所述滑轮亦可转动至安装卡槽内。本申请具有提高作业效率的效果。
