Abstract

The invention provides a device for polishing a welding seam inside a pressure vessel. The device comprises a moving base; a first angle adjusting device, wherein the first angle adjusting device is arranged at the upper end of the moving base; a mounting base, wherein the mounting base is arranged at the working end of the upper end of the first angle adjusting device, the to-be-polished pressure vessel is mounted at the upper end of the mounting base, and a dust suction device is further connected to the mounting base or the moving base. a fixed base, wherein the fixed base is located on one side of the moving base, and the moving base is provided with a limiting block used for being inserted into a limiting groove in the fixed base and locked through a locking piece; a sealing cover, wherein the sealing cover is detachably connected to the upper end of the mounting base, a first opening is formed in the side, close to a sealing head, of the sealing cover, a sealing door capable of being opened or closed is connected to the first opening, and a dust suction pipe of the dust suction device is connected to the sealing cover; and a polishing device, wherein the polishing device is installed at the upper end of the fixed base, and the polishing end of the polishing device extends into the pressure vessel to be polished from the first opening. By arranging the automatic polishing device, automatic polishing is achieved, workers are prevented from entering the vessel for polishing, and the device is safe, environmentally friendly and high in polishing efficiency.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a welding seam grinding device inside a pressure vessel. Background technique [0002] According to the "Special Equipment Safety Law of the People's Republic of China" and the special equipment safety technical specification "Stationary Pressure Vessel Safety Technical Supervision Regulations", in-use pressure vessels must undergo regular inspections to determine whether the inspected pressure vessels can operate safely to the next level. a test cycle. The most important item in the inspection is the non-destructive testing of buried defects and surface defects of the weld. Ultrasonic flaw detection and magnetic particle flaw detection are usually used to detect within the range of 100mm along both sides of the weld inside the container. However, before the inspection, both sides of the weld must be polished to remove rust and reveal the metallic luster before the inspection c...
