[0014] As described above, the retractable hanging basket for bridge maintenance of the present invention has the following beneficial effects:

[0015] The present invention designs the hanging basket into two interpenetrating parts, and the telescopic guiding mechanism forms an active connection with the left truss and the right truss that make up the hanging basket. In actual use, the left truss and the right truss that make up the hanging basket can be separated and approached according to the change of the transverse width of the bridge to achieve the widening function. The telescopic guiding mechanism provides guidance for the relative movement of the left truss and the right truss, ensuring the straightness of the relative movement of the left truss and the right truss, thereby improving the widening effect of the hanging basket; at the same time, the telescopic guiding mechanism can also form a connection between the left truss and the right truss, preventing the left truss and the right truss from being separated or damaged due to excessive relative movement, further improving the reliability of the widening of the hanging basket; the present invention can be applied to the maintenance of bridges with variable widths on the bridge deck and has good market application prospects.
