Well lid anti-falling net for municipal engineering
The well lid anti-falling net for municipal engineering comprises a well wall, a well lid body is installed at the top of the well wall, a bearing plate is installed in the well wall, a fixing column is installed on the upper surface of the bearing plate, and transmission screw rods are rotationally installed on the four surfaces of the outer portion of the fixing column; and the transmission screws are divided into two parts including forward screws and reverse screws, the bottom ends of the four sets of transmission screws penetrate through the bearing plate and extend to the bottom, and driven wheels are installed on the surfaces of the extending sections. A driven wheel is driven to rotate by rotating a driving wheel, a movable rod is driven to push a fixing plate outwards or inwards under the action of a transmission screw rod, so that the anti-falling net can adapt to hoistways of different specifications, meanwhile, the position of the fixing plate is adjusted outwards or inwards, and an anti-falling net body is fixed through one ends of pull ropes with the same length; and the other end of the spring is also mounted on the upper surface of the movable plate, so that the rigidity of the spring can be adjusted according to different use environments.
本发明公开了一种市政工程用井盖防坠网，包括井壁，所述井壁的顶部安装有井盖本体，所述井壁的内部安装有承载板，所述承载板的上表面安装有固定柱，所述固定柱外部的四个面均转动安装有传动螺杆，且传动螺杆分为正向螺杆和反向螺杆两个部分，四组所述传动螺杆的底端贯穿承载板延伸至底部，延伸段的表面安装有从动轮。本发明通过转动主动轮带动从动轮转动，在传动螺杆的作用下带动活动杆将固定板向外或者向内推动，使其能够适应不同规格的井道，同时通过向外或者向内调节固定板的位置，利用同等长度拉绳的一端固定防坠网本体，另一端同样安装在移动板的上表面，即可对弹簧的刚性进行调节，进而根据不同的使用环境，进行调节。
