An intelligent welding robot arm for power plant boiler maintenance

Abstract

The present invention relates to the technical field of welding manipulators, in particular to an intelligent welding manipulator for power plant boiler maintenance, including a bottom plate, a placement mechanism is fixedly connected to the bottom plate, and a first adjustment mechanism is provided on the placement mechanism. The first adjustment mechanism is provided with a second adjustment mechanism, the bottom plate is provided with a limit mechanism, the limit mechanism is provided with an auxiliary mechanism, and the limit mechanism is provided with a spraying mechanism; through the placement mechanism, it is convenient to realize The flexible up and down adjustment of the mechanical arm makes the maintenance work more convenient; the first adjustment mechanism is set on the placement mechanism to facilitate the flexible front and rear adjustment of the mechanical arm, and the second adjustment mechanism is set on the first adjustment mechanism to facilitate realization The flexible left and right adjustment of the mechanical arm further makes the maintenance work more convenient; the auxiliary mechanism is set in the limit mechanism, so that it is convenient and better to limit the uneven parts on the boiler, so as to ensure the limit of the boiler during welding. bit effect.

Description

technical field [0001] The invention relates to the technical field of welding manipulators, in particular to an intelligent welding manipulator for power plant boiler maintenance. Background technique [0002] In actual operation, power plant boilers are basically cylindrical. During long-term work, any part of the surface may need to be repaired by welding. Traditional manipulators similar to the arm of an excavator have relatively large differences in welding repair positions. In addition, after long-term use of power plant boilers that need to be overhauled, there may be some burrs or dirt on the surface, resulting in uneven surfaces, which will affect the limit effect during welding; Further, in the actual operation process, when it is necessary to add flux, it is inconvenient to add flux at any time because the welding part may be located on any part of the boiler surface. Contents of the invention [0003] Aiming at the problems in the prior art, the invention prov...

[0002] In actual operation, power plant boilers are basically cylindrical. During long-term work, any part of the surface may need to be repaired by welding. Traditional manipulators similar to excavator arms have relatively large differences in welding repair positions. In addition, after long-term use of power plant boilers that need to be overhauled, there may be some burrs or dirt on the surface, resulting in uneven surfaces, which will affect the limit effect during welding; Further, in the actual operation process, when it is necessary to add flux, since the welding part may be on any part of the boiler surface, it is inconvenient to add it at any time as needed
