Automatic leveling device for house building construction

The invention is applicable to the technical field of buildings, and provides an automatic leveling device for house building construction, which comprises a bottom box, a moving component mounted in the bottom box, a supporting box mounted at the top of the bottom box, a hydraulic cylinder I mounted on the bottom wall in the supporting box, a shell arranged above the supporting box, and a hydraulic cylinder II mounted on the bottom wall in the shell. A mechanism body is arranged on the top of the shell. The moving assembly comprises two moving wheels and a telescopic assembly used for driving the two moving wheels to stretch out and draw back. By arranging the two scraping assemblies, when a third motor drives a bidirectional lead screw to rotate, two nuts drive the two scraping assemblies to get close to each other, and compared with one scraping assembly, the device can accelerate the cleaning efficiency; by arranging the electric cylinder, when the electric cylinder works, the output shaft of the electric
