Problems solved by technology

[0004] The purpose of the present invention is to provide a turbogenerator frame assembly welding concentricity guarantee device to solve the problem that the existing vertical ring plate proposed in the background technology needs to use a leveling device to level the base plate when assembling. Afterwards, the vertical ring plates on the inner side are leveled sequentially, which makes the assembly process of the vertical ring plates more cumbersome and inconvenient to assemble the vertical ring plates

Abstract

The invention relates to a concentricity guarantee device for assembly and welding of a steam turbine generator base, which includes a base, a first screw rod and a positioning rod. In the transmission slot, a turbine is connected to the inside of the column close to the first transmission slot, wherein a worm is penetrated on a side of the base close to the turbine, and a first motor is fixed on one side of the base. The base of the steam turbine generator is equipped with a welding concentricity guarantee device. After the ring plates are placed in sequence, the first screw rod drives the positioning block to move to the inner side of the ring plate, so that the positioning block drives the positioning rod to enter the interior of the positioning groove. , through the positioning rod and the positioning groove, it is convenient to fix the ring plate and the positioning block, and the positioning block is used to position the ring plate, so that the center of the ring plate coincides with the center of the column, so that the centers of the ring plates of different layers coincide. Position the welding of the ring plate.

Description

technical field [0001] The invention relates to the technical field of turbogenerators, in particular to a concentricity guarantee device for assembly and welding of a turbogenerator base. Background technique [0002] Turbogenerator refers to a generator driven by a steam turbine. The superheated steam generated by the boiler enters the steam turbine and expands to do work, turning the blades to drive the generator to generate electricity. The turbogenerator base is composed of 6 to 10 vertical ring plates. The design requires a concentricity of about 3mm. [0003] When the existing vertical ring plates are combined, it is necessary to use a leveling device to level the base plate, and then to level the inner vertical ring plates in turn, which makes the vertical ring plate assembly process more cumbersome and inconvenient for vertical ring plates. Therefore, we propose a welding concentricity guarantee device for turbogenerator frame assembly, so as to solve the problems ...
