The invention relates to the field of anti-falling nets, and aims at providing a well lid anti-falling net for municipal engineering. The well lid anti-falling net comprises a lid body and a well body, wherein clamping grooves distributed in an annular structure are formed in the outer side wall of the top of the lid body, inserting grooves distributed in an annular structure are formed in the inner side wall of the top of the well body, inserting blocks are inserted into the inserting grooves, barbs distributed in an annular structure are welded to the outer side walls of the inserting blocks, the barbs are installed inside the inserting blocks in a penetrating mode, sliding grooves are formed in the outer walls of the other ends, away from the inserting grooves, of the inserting blocks, sliding installation plates inserted into the clamping grooves are slidably connected to the interiors of the sliding grooves, and positioning grooves are formed in the middles of the outer walls of the two sides of the lid body. The well lid anti-falling net has the beneficial effects that through arrangement of positioning columns, when an operator rotates a first rotating rod, the first rotating rod pushes the positioning columns to be inserted into limiting inserting grooves through mutual matching use of first gears, second gears, second rotating rods, threaded columns and threaded grooves, and then the safety performance of the device is improved.
本发明涉及防坠网领域，目的在于提供一种市政工程用井盖防坠网，包括盖体和井体，盖体的顶部外侧壁上开设有呈环形结构分布的卡槽，且井体的顶部内侧璧上开设有呈环形结构分布的插槽，插槽的内部插接有插块，且插块的外侧璧上焊接有呈环形结构分布的倒钩，倒钩贯穿安装至插块的内部，插块远离插槽的另一端外壁上开设有滑槽，且滑槽的内部滑动连接有插接至卡槽内部的滑动安装板，盖体的两侧外壁中部开设有定位槽。本发明的有益效果在于通过设置的定位柱，当操作者转动一号转杆时，一号转杆通过一号齿轮、二号齿轮、二号转杆、螺纹柱和螺纹槽的相互搭配使用推动定位柱插接至限位插槽的内部，进而提升了该装置的安全性能。
