Description

Technical Field

[0001] The invention relates to a method for butting and forming a duct of a wind turbine duct frame, and belongs to the technical field of offshore wind power construction. Background Art

[0002] Offshore wind power development can, to some extent, address the shortcomings of clean energy. Offshore wind turbines must be installed on the sea surface using a wind turbine jacket as a foundation. The jacket must withstand the static load of the turbine's upper weight and the dynamic load of the sea breeze.

[0003] When individual pipe segments (steel pipe piles) are butt-welded for wind turbine jackets, the quality of the girth weld layer determines the quality of the resulting jacket. Conventional methods involve placing the pipe segments on a rolling device for rolling, followed by welding to form the butt joints (see Chinese Patent Publication No. CN217452715U). However, manual welding can easily cause the pipe segments to roll, preventing them from maintaining a stable, fixed position. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for butting and forming ducts of a fan duct rack.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for butt-jointing and forming a duct of a fan duct frame, comprising: a butt-jointing and forming process in which two duct sections are placed in a stable and fixed posture on a duct butt-jointing and forming frame.

[0007] The catheter docking forming frame comprises:

[0008] Slide rails fixed on the ground of the dock building;

[0009] The rotating roller seat can be slidably matched on the slide rail, and rotating rollers are rotatably installed at the four corners of the rotating roller seat;

[0010] An external friction assembly for the pipe joint that frictionally clamps both sides of the outer periphery of the pipe joint;

[0011] The linked peristaltic tube is laid inside the two pipe sections.

[0012] There are two rotating roller seats, which slide on the slide rails pushed by hydraulic rods. The hydraulic rods are fixed on the ground of the dock factory building to control the width of the girth welds between the pipe sections.

[0013] The external friction component of the pipe segment is composed of a rotating seat, a rotating arm and a friction plate formed by a discarded outer tire.

[0014] The rotating arm is pulled by being connected through a hydraulic telescopic cylinder, and the hydraulic telescopic cylinder is fixed on the ground of the dock factory building.

[0015] The rotating arm can rotate in the rotating seat groove; the rotating arm cooperates with the inclined surface of the rotating seat to perform interference and limiting.

[0016] The linked peristaltic tube is connected with a liquid inlet valve and a liquid discharge valve.

[0017] The butt-jointing forming process includes the outer diameter surfaces of the two pipe segments being relatively frictionally clamped by the friction plates, and the inner and outer diameter surfaces of the two pipe segments being correspondingly limited by the linked peristaltic tube and the friction plates, so that the outer diameter surfaces of the two pipe segments are stabilized and fixed by the friction plates;

[0018] When the rolling position of the two pipe sections needs to be adjusted, the rotating arm opens outward with the friction plate, the linked peristaltic tube completely discharges the internal water, and the linked peristaltic tube is taken out from the pipe section. After the two pipe sections are rolled on the rotating roller to complete the adjustment, the linked peristaltic tube is re-laid into the inner diameter of the two pipe sections, and the rotating arm brings the friction plate inward to closely contact the outside of the pipe section.

[0019] The beneficial effect of the present invention is that the inner and outer diameter surfaces of the two pipe sections are limited by the linked peristaltic tube and friction plate, ensuring that the two pipe sections are in a stable fixed posture, solving the problem that the pipe sections are prone to rolling and cannot be in a stable fixed posture.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0027] like Figures 1 to 5 shown.

[0028] A method for butting and forming a duct of a fan duct frame according to the present application comprises:

[0029] The pipe section 1 of the catheter can roll on the rotating rollers 2 , and four rotating rollers 2 support one pipe section 1 .

[0030] The four rotating rollers 2 can be rotatably mounted on the four corners of the rotating roller seat 3. There are more than two rotating roller seats 3. The rotating roller seats 3 are pushed by the hydraulic rod 31 to slide on the slide rail 4, so that the pipe sections 1 slide relative to each other and dock to control the width of the girth weld 11.

[0031] The bottom of the rotating roller seat 3 is provided with a groove which can slidably cooperate with the slide rail 4, and the slide rail 4 is fixed on the ground 5 of the dock workshop.

[0032] The outer periphery of the pipe segment 1 is frictionally clamped by the external friction assembly 6, which consists of a rotating base 61, a pivoting arm 62, and a friction plate 63 made of discarded outer tires. The pivoting arm 62 is pulled by a hydraulic telescopic cylinder 63, tightening inward or expanding outward within the groove of the rotating base 61. The pivoting arm 62 cooperates with the inclined surface of the rotating base 61 to prevent positional interference. The rotating roller base 3, the slide rail 4, the external friction assembly 6, and the linked peristaltic tube 7 form the catheter docking and forming frame.

[0033] Inside the two pipe segments 1, a linked peristaltic tube 7 made from recycled automobile inner tubes is laid. The hollow interior of the linked peristaltic tube 7 allows water to flow in through an inlet valve 71 and out through a drain valve 72. The rubber material of the linked peristaltic tube 7 itself has a certain degree of elasticity. When the two pipe segments 1 tend to rotate relative to each other, the linked peristaltic tube 7 rubs against the inner diameter surfaces of the two pipe segments 1, keeping the inner diameter surfaces of the two pipe segments 1 in a stable position through the linked peristaltic tube 7.

[0034] The outer diameter surfaces of the two pipe segments 1 are frictionally clamped against each other by the friction plates 63, so that the outer diameter surfaces of the two pipe segments 1 are stabilized by the friction plates 63. When the rolling position of the two pipe segments 1 needs to be adjusted, the rotating arm 62 with the friction plates 63 is opened outward, and the linked peristaltic tube 7 completely drains the internal water. The linked peristaltic tube 7 is removed from the pipe segment 1. After the two pipe segments 1 are adjusted by rolling on the rotating rollers 2, the linked peristaltic tube 7 is re-laid into the inner diameter of the two pipe segments 1, and the rotating arm 62 with the friction plates 63 is moved inward to closely contact the outside of the pipe segment 1.

[0035] The inner and outer diameter surfaces of the two pipe sections 1 are limited by the linked creeping tube 7 and the friction plate 63, ensuring that the two pipe sections 1 are in a stable fixed posture, solving the problem that the pipe sections are prone to rolling and cannot be in a stable fixed posture; when manual welding is performed, the quality of the bad welds between the manually welded pipe sections is not affected, and the quality of the duct docking and forming of the fan duct frame is improved, thereby improving the stability of the fan foundation in the later stage.
