The invention relates to a spherical concrete leveling device. The spherical concrete leveling device comprises a middle shaft, the bottom end of the middle shaft is fixed through a base steel plate,a rotating barrel close to the upper portion is hinged to the exterior of the middle shaft, and a movable clamping ring which is mounted on the middle shaft is arranged at the lower end of the rotating barrel; the upper end of the rotating barrel is fixedly connected with a belt pulley which is hinged to the middle shaft, the belt pulley is connected with a motor, a sleeve is mounted at the top end of the middle shaft, at least three uniformly-distributed supporting steel pipes are connected to the side face of the sleeve, and a clamping fixing steel plate is connected to the ends of the supporting steel pipes; and a plurality of connecting steel pipes stretch out from the two sides of the side face of the rotating barrel, the connecting steel pipes are symmetrically distributed on both sides of the rotating barrel and are tilted downwards and shortened in sequence, and the two sides of the rotating barrel are further provided with arc-shaped leveling frames which are connected throughthe connecting steel pipes and symmetrical. Compared with an existing manual leveling method, the spherical concrete leveling device can quickly find out the spherical concrete surface, the levelingprecision is high, the cost is low, and the appearance quality is good.
