Abstract

The invention relates to an automatic creeping detection device for welding seams of wind turbine towers and a detection method thereof. At present, the existing flaw detection for welding seams of wind turbine towers can only be performed by the inspection personnel on places such as platforms or ladders, and welding seams at the higher part inside the tower cannot be detected. The automatic creeping detection device for welding seams of wind turbine towers comprises: a controller (1), a trolley A (2) and a trolley B (3). The controller is mounted on the top of the trolley A. The controller is connected to one end of a connecting wire. A probe (5) is connected to the other end of the connecting wire (4). The trolley B and the trolley A are connected by a sliding rail. The sliding rail isinstalled at the bottom of the trolley B. The main structure of the trolley A and the trolley B are the same, but the size is different. The trolley A and the trolley B are placed on the wall of the wind turbine tower to be detected. The automatic creeping detection device for welding seams of wind turbine towers and the detection method thereof are applied to the flaw detection and detection of the wind turbine towers.

Description

Technical field: [0001] The invention relates to an automatic crawling fan tower welding seam flaw detection device and detection method. Background technique: [0002] The wind power tower is the tower pole of wind power generation, which mainly plays a supporting role in the wind power generation unit and absorbs the vibration of the unit at the same time. The welding seam detection of the wind turbine tower is a key inspection test in the operation stage of the wind farm. The connection of the weld seam is related to the safe operation of the wind turbine, and at the same time reflects the frequent changes in the operating conditions and the frequent changes in the tower load. Carrying capacity. At present, the flaw detection of the existing fan welds can only be carried out by inspectors on the platform or ladder, but the welds in the higher parts of the tower cannot be detected. Invention content: [0003] The object of the present invention is to provide an automat...
