[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flywheel housing lifting tool, including a welding assembly, the welding assembly including a steel plate and a cylinder, the cylinder is arranged at the lower end of the steel plate, a connecting bolt passes through the cylinder, the connecting bolt is threadedly connected to the threaded hole on the upper part of the flywheel housing, and a threaded lifting ring is arranged at the upper end of the steel plate.

[0005] As a preferred technical solution of the utility model, through holes are evenly distributed around the steel plate, and the cylinder is arranged at the corresponding position of the through holes.

[0006] As a preferred technical solution of the utility model, the cylinder and the steel plate are connected by welding.

[0007] As a preferred technical solution of the utility model, a center hole is provided at the center position of the steel plate, the upper end of the threaded lifting ring is a lifting ring, a stud is welded to the lower end of the threaded lifting ring, the stud passes through the center hole, and a nut is threadedly connected to the outer side of the stud.

[0008] As a preferred technical solution of the utility model, a small gasket is arranged between the head of the connecting bolt and the steel plate.

[0009] As a preferred technical solution of the utility model, a large gasket is arranged between the nut and the steel plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the flywheel housing lifting tool is reasonably designed and ingeniously conceived. By arranging a cylinder on the welding assembly and connecting the threaded holes on the flywheel housing with connecting bolts, the welding assembly and the flywheel housing are stably fixed without damaging the flywheel housing. By arranging a threaded lifting ring on the welding assembly, it is convenient to lift the flywheel housing with a jumping vehicle and a crane, thereby improving the safety of the lifting process.
