Problems solved by technology
[0003] However, when welding or pouring the second gap C2' between the connecting pipe 3 and the second vertical tubular busbar 2 below, it is necessary to weld or pour the gap upwards, and the solder or pouring material is not easy to enter the gap under the action of gravity and It is easy to move down, and due to the limited space in the wind power tower, and the welding or pouring of the tubular busbar needs to be seamless around, the welding or pouring operation is difficult, and the welding or pouring takes a long time

Embodiment Construction
[0020] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.
[0021] see figure 2 with image 3 , the method for connecting two vertical connecting pipes of the present invention connects the first vertical connecting pipe 1 and the second vertical connecting pipe 2 through an intermediate connecting pipe 3 . The intermediate connecting pipe 3 has a wide-body pipe 31 and a narrow-body pipe 32 communicated with the wide-body pipe 31. The diameter of the wide-body pipe 31 is greater than the diameter of the narrow-body pipe 32, including the following steps:
[0022] First of all, S1, insert the lower part of the narrow body tube 32 of the intermediate connecting tube 3 into the upper lumen of the second vertical connecting tube 2, and a first opening facing upward is formed between the narrow body tube 32 and th...

The invention discloses a method for connecting two vertical connecting pipes. A first vertical connecting tube and a second vertical connecting tube are connected by an intermediate connecting tube,and the intermediate connecting tube is provided with a wide-body tube and a narrow body tube. The method includes the following steps: inserting a lower portion of the narrow-body tube of the intermediate connecting tube into a pipe cavity of the upper end of the second vertical connecting tube, and forming a first step gap with an opening facing upward between the narrow-body tube and the secondvertical connecting tube; inserting the lower end of the first vertical connecting tube into the wide-body tube of the intermediate connecting tube, and forming a second step gap with the opening facing upward between the wide-body tube and the first vertical connecting tube; and respectively welding or pouring the first step gap and the second step gap. According to the method, since the openings of the first step gap and the second step gap are all facing upward, solder or the castable easily enters the gaps from above under the gravity force during welding or pouring, so that the welding or pouring is easy, and the welding and pouring time are short and effects are good.
Description
technical field [0001] The invention relates to a method of connecting two vertically connected pipes. Background technique [0002] see figure 1 , in the field of wind power, the upper and lower vertical tubular busbars 1 and 2 of the wind power tower are butt welded together through a connecting pipe 3, wherein the lower end of the first vertical tubular busbar 1 located above is sleeved on the connecting pipe 2 There is a first slit C1' formed in the upper lumen, and the upper end of the second vertical tubular busbar 2 located below is sleeved in the lower lumen of the connecting pipe 3 and a second slit C2' with the opening facing downward is formed, and then The first gap C1' and the second gap C2' are respectively welded or cast. [0003] However, when welding or pouring the second gap C2' between the connecting pipe 3 and the second vertical tubular busbar 2 below, it is necessary to weld or pour the gap upwards, and the solder or pouring material is not easy to en...
