Abstract

The invention discloses an automatic leveling device used for ends of a supporting box girder in a jacking formwork system. The automatic leveling device comprises leveling hydrocylinders, a gravity sensor level measuring instrument and a control center, wherein the leveling hydrocylinders are symmetrically and fixedly arranged at the two ends of the supporting box girder; the gravity sensor level measuring instrument is arranged in the middle of the supporting box girder. The gravity sensor level measuring instrument collects data of the level of the supporting box girder and transmits a signal to the control center, and the control center controls the two hydrocylinders to ascend and descend. When the supporting box girder is supported on supports of which the elevations have deviations, the gravity sensor level measuring instrument installed on the box girder collects the data and transmits the data to the control center, and the leveling hydrocylinders installed at the ends of the box girder ascend or descend to achieve automatic leveling; in this way, manual measurement and adjustment aiming at guaranteeing the level of the supporting box girder are avoided, a lot of labor and time are saved, and safety risks and the construction cost are lowered.
