The invention provides a double-shear-fork hydraulic lifting platform with a leveling device. A plurality of shear forks are symmetrically arranged on the front side and the rear side of the bottom of a workbench. The workbench is connected with a shear fork base through the shear forks. An upper connecting frame and a lower connecting frame are arranged between the shear forks symmetrically arranged on the two sides of the workbench, and a lifting oil cylinder is hinged between the upper connecting frame and the lower connecting frame. The leveling device is arranged below the shear fork base. According to the double-shear-fork hydraulic lifting platform with the leveling device, the platform is controlled to rise and fall through a hydraulic oil cylinder, and therefore the platform can stably rise and fall and can stop at any position. Four leveling oil cylinders make telescopic action reversely, and therefore the leveling action can be accurate, powerful and fast. The whole platform is installed on the top of a maintenance car, fast moves on a track along with the maintenance car and reaches a maintenance position in time, and the online work requirement can be met well.
