Abstract
The present invention discloses an automatic grinding device for weld beading on the inner wall of a pipeline with a large length to diameter ratio. The automatic grinding device includes a supporting module, and a walking module, a working module and a control module which are arranged on the supporting module, where the walking module is used for moving the supporting module to the butt welding position of the pipeline; the working module is used for grinding the weld beading; and the control module is used for controlling the actions of the walking module and the working module. When the pipeline rotates along the axial direction, the position of the grinding device can remain at the bottom of the pipeline, rather than rotating together with the pipeline, and the elimination of weld beading on the whole circumference at the butt welding position of the pipeline is realized.
