The invention belongs to the technical field of steam turbine generator maintenance in the power industry, and particularly relates to a steam turbine generator rotor pulling traction support and a ground anchor device, which comprises an anchor bottom plate, a bolt A, a gasket A, a traction support, a traction cross beam and a middle lifting lug plate. The anchor bottom plate is connected with the traction support through the bolt A. The gasket A is further arranged between the anchor bottom plate and the traction support. The traction cross beam is fixedly connected with the traction supportthrough bolts, and the middle lifting lug plate is installed in the middle of the traction cross beam. A traction end A and a traction end B are respectively arranged at the left end and the right end of the traction cross beam; and a traction end C is also arranged on the middle lifting lug plate. The single-point and two-point traction functions are achieved, the traction mode can be selected according to the actual situation so as to guarantee stable operation in the rotor pulling process, a coupler is prevented from touching a stator iron core, and equipment damage is effectively prevented. In addition, the traction center is adjustable, and the support is detachable.
