Pipe bending device for overhauling steam turbine of thermal power plant

The utility model discloses a pipe bending device for overhauling a steam turbine of a thermal power plant, which comprises a supporting rod acting on installation basic equipment, the top of the supporting rod is connected with a first limiting plate, the top of the first limiting plate is provided with a second limiting plate, and the second limiting plate is connected with the supporting rod. A bending wheel is connected between the second limiting plate and the first limiting plate and acts on a bent steel pipe; and the hydraulic rod is fixedly connected to the top of the supporting rod. According to the pipe bending device for overhauling the steam turbine of the thermal power plant, firstly, the first sliding block is pulled to move through the two-way threaded rod, the first sliding block can drive the bending wheels to be close to each other, and therefore the distance between the bending wheels can be conveniently adjusted, then the contact area between the supporting rod and the ground can be increa
