Problems solved by technology
Due to the limitation of the length of the steel pipe in the manufacturing of large-diameter steel pipe coiling, it is necessary to lengthen the segmental butt joint of the large-diameter and super-long round steel pipe. There is a problem of misalignment when the two segments of the same diameter steel pipe are butt-jointed. The local adjustment of single-section steel pipes makes it difficult to ensure the complete seamless connection of two-section steel pipes, which leads to difficulties in the connection of large-diameter steel pipes, and directly affects the precision and efficiency of large-diameter steel pipe connections, and also affects the performance and reliability of the entire equipment; at the same time There are many specifications of large-diameter round steel pipes required in offshore wind power equipment, and it is difficult to meet all the specifications of large-diameter round steel pipes that need to be adjusted, which limits the production and manufacturing of large-diameter steel pipes

Embodiment Construction
[0017] Now further illustrate how the present invention is implemented in conjunction with accompanying drawings:
[0018] The large-diameter round steel pipe butt joint adjustment device is composed of a mobile trolley 1, a trolley mobile platform 2 and an adjustment mechanism 3. The adjustment mechanism consists of a hydraulic cylinder fixing bracket 3-b, a hydraulic cylinder 3-c, and the adjustment of the fan-shaped arc surface The pad 3-a is composed of the hydraulic cylinder fixing bracket 3-b, which is composed of two groups of left and right symmetrical cross box beams, and the left and right groups of four sets of hydraulic cylinders 3-c are respectively connected to the top panels of the left and right two groups of cross box beams. The flange plate is connected, and the ball heads of each hydraulic cylinder 3-c are respectively connected with an adjustment pad 3-a; when the adjustment mechanism is working, between two butt-connected large-diameter round steel pipes, t...

The invention provides a large-diameter circular steel tube butt joint adjusting device, and belongs to the field of welding equipment. The large-diameter circular steel tube butt joint adjusting device is composed of a moving trolley, a trolley moving platform and an adjusting mechanism. The adjusting mechanism is composed of hydraulic oil cylinder fixing supports, hydraulic oil cylinders and adjusting cushion blocks. The hydraulic oil cylinder fixing supports are composed of a left set of cross-shaped box beams and a right set of cross-shaped box beams, wherein the left set of cross-shaped box beams and the right set of cross-shaped box beams are symmetrical. The left set of hydraulic oil cylinders and the right set of hydraulic oil cylinders respectively comprise four hydraulic oil cylinders which are connected with face plates at the top ends of the left set of cross-shaped box beams and face plates at the top ends of the right set of cross-shaped box beams through flange plates respectively, and ball heads of the hydraulic oil cylinders are connected with the adjusting cushion blocks respectively. The adjusting mechanism is arranged between two butt joint large-diameter circular steel tubes, two segments of the large-diameter steel tubes with the same diameter are synchronously adjusted through the four hydraulic oil cylinders which are symmetrical left and right, then, the apertures of the butt joint ends of the two segments of the large-diameter steel tubes completely coincide, the steel tubes are welded in a butt joint mode, and therefore butt joint accuracy and efficiency of the large-diameter steel tubes are remarkably improved. The large-diameter circular steel tube butt joint adjusting device is scientific and simple in design and convenient to operate, and meets the requirements for adjustment and butt joint of the large-diameter steel tubes of various specifications.
Description
technical field [0001] The invention discloses a large-diameter circular steel pipe butt joint adjustment device, which belongs to the field of welding equipment. Background technique [0002] Large-diameter round steel pipes (diameter ≥ 2m) are widely used in construction, especially in the manufacture of wind towers for offshore wind power equipment, large-diameter round steel pipes are widely used. Due to the limitation of the length of the steel pipe in the manufacturing of large-diameter steel pipe coiling, it is necessary to lengthen the segmental butt joint of the large-diameter and super-long round steel pipe. There is a problem of misalignment when the two segments of the same diameter steel pipe are butt-jointed. The local adjustment of single-section steel pipes makes it difficult to ensure the complete seamless connection of two-section steel pipes, which leads to difficulties in the connection of large-diameter steel pipes, and directly affects the precision and...
