Auxiliary measuring equipment for urban rail

The invention discloses auxiliary measuring equipment for urban rail. The equipment comprises a first supporting beam, a second supporting beam, a supporting frame, a rail wheel, a positioning rod, arail inclination angle measuring assembly, a distance checking assembly and a positioning spring. The first supporting beam and the second supporting beam are arranged side by side. Rail wheels are installed on the bottom sides of the first supporting beam and the second supporting beam respectively, the distance checking assembly is installed on the top side of the first supporting beam, the railinclination angle measuring assembly is installed on the bottom side of the second supporting beam, and by arranging the distance checking assembly, when the first supporting beam and the second supporting beam advance along a rail, if the distance between the tracks is increased or decreased, electrode balls deviate to be in contact with conductive poking pieces on the two sides, an access is achieved between a battery a
