Steam turbine generator base assembling and welding concentricity guaranteeing device

Abstract

The invention relates to a steam turbine generator base assembling and welding concentricity guaranteeing device. The device comprises a base, a first lead screw and a positioning rod, a stand columnis rotationally connected to the top of the base, a first transmission groove is formed in the bottom, close to the stand column, of the base, a worm gear is connected to the interior, close to the first transmission groove, of the stand column, a worm penetrates through the side, close to the worm gear, of the base, and a first motor is fixed to one side of the base. According to the steam turbine generator base assembling and welding concentricity guaranteeing device, after annular plates are sequentially placed, the first lead screw drives a positioning block to move towards the inner sidesof the annular plates, so that the positioning block drives the positioning rod to enter the inside of a positioning groove conveniently, through the positioning rod and the positioning groove, the annular plates and the positioning block are fixedly connected conveniently, the annular plates are positioned through the positioning block, the circle centers of the annular plates coincide with thecircle center of the stand column, the circle centers of the annular plates on different layers coincide conveniently, and welding of the annular plates is positioned.

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 ...

AI Technical Summary

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
