Telescopic adjustable weld joint grinding machine

Abstract

The invention discloses a telescopic adjustable weld joint grinding machine. The middle portion of a walking wheel platform is in an arch shape. The arch portion is provided with holes, and hooks are installed in the holes. A dust suppression apron is arranged on the hooks. Sliding wheels are arranged on a base plate below the walking wheel platform. All connecting plates of each linkage mechanism are hinged. The head ends of the connecting plates are fixedly connected with locating blocks welded to the inner face of an operation platform. The tail ends of the connecting plates are fixedly connected with locking blocks welded to the walking wheel platform. The two linkage mechanisms are connected in the mode that levers penetrate through hinged holes. The upper end of a threaded limiting device is connected with the operation platform. The lower end of the threaded limiting device is connected with the walking wheel platform. The middle portion of the threaded limiting device is provided with a screw-type limiter and a damping rod in a screw thread fit mode. A motor and a spirit level are arranged on the face of the operation platform. The motor conveys power through a belt wheel to drive a flying wing wheel to rotate. The periphery of the whole telescopic adjustable weld joint grinding machine is comprehensively sealed through aluminum alloy sheets.

Description

Technical field: [0001] The invention relates to a telescopic and adjustable welding seam grinding machine, which is suitable for welding seam and grinding of containers, and is especially suitable for welding seam grinding of long and large equipment such as towers. Background technique: [0002] With the rapid development of pressure vessel design and manufacturing technology, more and more medium and high pressure vessels are designed by stress analysis. In consideration of specification requirements and reducing stress corrosion, most of the equipment designed by stress analysis requires that all welds be ground Flat (not lower than the base material, and the residual height is 0-0.5mm), which undoubtedly increases the manufacturing cycle and cost. At the same time, the traditional grinder grinding, because of its poor quality and low efficiency, is no longer suitable for the requirements of modern manufacturing technology. .
