The application discloses a leveling device and method for bridge support assembly and belongs to the technical field of bridge support assembly; the leveling device comprises a supporting frame, a conveyor and a pressure applying and leveling assembly; the pressure applying and leveling assembly applies pressure through a leveling oil cylinder, then height adjustment and state detection are realized with the help of the leveling oil cylinder and a distance sensor, and a pressure sensor is arranged between the leveling oil cylinder and a horizontal fixing plate to monitor pressure; manual operation is replaced by mechanical automation, the efficiency of bridge support assembly is remarkably improved, accurate measurement and control are realized through the sensor, human errors are avoided, leveling precision and assembly quality are improved, human cost and labor intensity are reduced, and reliable guarantee is provided for bridge support assembly.

The utility model relates to the technical field of furniture surface paint film physical and chemical performance tests, in particular to a paint film impact resistance test grid drawing template which comprises a transverse drawing plate and a vertical drawing plate which are used in cooperation, a transverse line groove is formed in the transverse drawing plate, a vertical line groove is formed in the vertical drawing plate, and the transverse line groove is communicated with the vertical line groove. A plurality of transverse line grooves and a plurality of vertical line grooves are arranged at intervals, and the transverse line grooves and the vertical line grooves are mutually perpendicular when used in cooperation, a worker only needs to align the transverse marking plate and the vertical marking plate to the upper left corner of a test piece in sequence, and transverse lines and vertical lines which are perpendicular to each other are rapidly drawn through the transverse line grooves and the vertical line grooves; by means of the mode, the grid drawing process is greatly simplified, the grid drawing time is greatly shortened, the test efficiency is remarkably improved, meanwhile, due to the prefabricated transverse line grooves and the prefabricated vertical line grooves, it is ensured that the line positions are accurate, manual measurement errors are avoided, it is ensured that the drawn grids strictly meet the standard requirements, and the grid drawing accuracy is improved.
