AI Technical Summary
The length of the existing foundation pit protection device for construction is fixed, which is inconvenient to adjust, and the protective net needs to be replaced as a whole when it is damaged, resulting in a large loss.
A foundation pit protection component for municipal construction is designed, and a protective net structure with adjustable length is controlled. The expansion and storage of the protective net is controlled through the worm gear and worm transmission. Combined with a slidable bracket and limiting rod, the local replacement and shape adjustment of the protective net are realized.
It realizes flexible adjustment of the length of the protective net, and the mesh cover can be replaced separately when partially damaged, reducing the loss of overall replacement and improving the stability and fit of the protective net.
