Autonomously movable assembly type variable-cross-section continuous beam bridge overhauling hanging basket

The invention belongs to the technical field of constructional engineering, and discloses an autonomously movable assembly type variable-cross-section continuous beam bridge overhauling hanging basket. The overhauling hanging basket comprises a horizontal truss working table, vertical supporting columns, centering joints, horizontal rotating devices, vertical hydraulic telescopic devices and horizontal movement devices. Trusses serve as horizontal stress components, and the centering joints are arranged between the trusses, so the connection between the trusses at the two ends of each centering joint is realized. The horizontal rotating devices are arranged at the two ends of the horizontal truss working table, and the horizontal trusses and the vertical supporting columns are connected through the horizontal rotating devices. The vertical hydraulic telescopic devices are arranged on the vertical supporting columns and can be stretched out and drawn back, and the requirements of working platforms at different
