Crawling ladder for hydraulic engineering maintenance

The utility model relates to the technical field of hydraulic engineering, in particular to a hydraulic engineering maintenance ladder stand which comprises a loading plate, a positioning base is arranged on the lower left side of the loading plate, a matched positioning guide rail is slidably installed at the bottom of the positioning base, and a ladder stand assembly is arranged on the right side of the bottom of the loading plate. The ladder stand assembly can be stably mounted and used through connection of the positioning base and the fixing face, and the loading plate can be movably used through sliding connection between the positioning guide rail and the positioning base, so that the ladder stand assembly is movably used, the use effect of the ladder stand assembly on water conservancy project maintenance is better, and the practicability is high. The hydraulic push rod can act on the first adapter plate, so that the connecting angle between the bearing plates between the ladder stand plates is change
