Abstract

The invention discloses a welding device and a welding method for a steel pipe pile shear ring. The welding device is used for a steel pipe pile which is horizontally arranged on a roller frame in a rolling manner, and comprises a supporting beam which horizontally penetrates through the steel pipe pile, wherein supporting bases which are fixed on the ground are arranged at the two ends of the supporting beam; a travelling trolley which moves in the axial direction of the steel pipe pile is arranged on the supporting beam; a positioning part which can swing in the axial direction of the steel pipe pile is mounted on the travelling trolley; the positioning part extends towards the inner wall of the steel pipe pile; the end part of the positioning part is equipped with a roller which rotatably abuts against the inner wall of the steel pipe pile; a swinging device which can swing in the axial direction of the steel pipe pile is arranged on the positioning part; and a welding gun which faces towards the inner wall of the steel pipe pile is mounted on the swinging device. The welding device for the steel pipe pile shear ring can improve welding efficiency of the steel pipe pile shear ring, and improves welding quality of the shear ring.

Description

technical field [0001] The invention relates to the technical field of offshore wind power equipment, in particular to a welding device and a welding method for a steel pipe pile shear ring. Background technique [0002] In offshore wind power projects, there are shear ring accessories on the top of the pile. The length of the shear ring on the top of the pile is about 6 meters, including a total of 21 rings, and the range of the shear ring at the bottom of the pile is 8 meters, including a total of 13 rings. The shear ring is The round steel, the shear ring and the pile wall are welded in the form of double-sided fillet welds. The diameter of the pile group is about 2400mm, and the workload of welding the shear ring in a single pile group is as high as 498 meters. The steel pipe pile is generally a round pipe with a diameter of about 2.5m and a length of about 70 meters. The welding of the shear ring on the steel pipe pile The length is about 10m. At present, manual weld...
