【detailed description】

The technical features of the present invention will be further described in detail below in conjunction with the accompanying drawings to facilitate the understanding of those skilled in the art.

A folding barrel-shaped tower, as shown in Figures 1 to 10, includes a bottom flange 1 and a barrel-shaped cylinder 3 arranged on the bottom flange 1, the cylinder 3 is composed of multiple pieces It is spliced by longitudinally bent flaps. The upper and lower ends of the cylinder body 3 are open, forming a barrel shape together with the bottom flange 1 . The folded plate is a steel plate. The reason why the present invention is called a folded and assembled tower is because the tower is formed by bending and further assembling straight steel plates. By bending the steel plates, the original steel plate that cannot stand upright can be Standing upright greatly increases its strength. Using this splicing method, a tower with a length of more than 60 meters and a diameter of more than 3.6 meters can be produced, and it is very convenient to manufacture, hoist, and transport. Spraying is generally used for anticorrosion, and its service life is only a few years. This application adopts integral hot-dip galvanized anticorrosion, and the anticorrosion service life can be as long as 30 years.

Because the tower is assembled from multiple folded plates, the folded plates are small in size and convenient for road and sea transportation. The existing large-scale offshore wind turbine towers do not have super-high large-scale offshore cranes. Therefore need to use helicopter to lift the tower tube, but adopt the tower tube of the present invention, even can not need to adopt the hoisting of large-scale crane, can adopt the mode of segmental assembling fully, have reduced hoisting cost greatly.

As mentioned above, the folded barrel-shaped tower tube, the folded plate includes a connecting plate 2 located on both sides of the folded plate and bent toward the inside of the tube, and a tube wall plate 4 located between the two connecting plates 2. Two adjacent connecting plates 2 are bonded and fixedly connected by bolts 9, so as to splice a plurality of tube wall plates 4 into a tube shape. The connecting plate plays the role of connecting the flange, and this structure does not need to weld the flange, and the assembly is simple and fast. The folded plate is composed of a connecting plate 2 and a tube wall plate 4, and is one piece.

In the above-mentioned folded barrel-shaped tower, the cylinder body 3 includes multiple sections, and the two adjacent sections of the cylinder body 3 are connected and fixed by a plurality of bolts 9, and the connection ends of the adjacent two sections of the cylinder body 3 are respectively Two symmetrical notches 5 are cut, as shown in Figure 5, the main function of the notch 5 is to facilitate the sleeve installation between the upper and lower cylinders 3, because the connecting plate 2 will produce an inward The convex ribs will hinder the socket installation between the upper and lower cylinders 3, so it is necessary to reserve a gap 5; the secondary function of the gap 5 is to relieve part of the stress.

As for the above-mentioned folded barrel-shaped tower, there is also a semicircular opening 6 at the gap 5, as shown in FIG. 5 . The main function of the semicircular opening 6 is to eliminate stress and prevent the subsequent cracking and twisting of the folded plate; the secondary function is to facilitate the installation of the rib plate 7 described below.

Further, as shown in FIG. 1 , the cylinder 3 includes a first section of cylinder 301 connected to the bottom flange 1 , a second section of cylinder 302 connected to the upper end of the first section of cylinder 301 , and a second section of cylinder 302 connected to the upper end of the first section of cylinder 301 . The upper end of one section of cylinder 301 is fixed on the inner side of the second section of cylinder 302, and the second section of cylinder 302 is socketed on the first section of cylinder 301, just like a pen holder is socketed on a pen holder.

In the above-mentioned folded barrel-shaped tower, the bottom flange 1 is a folded flange, which is formed by splicing a plurality of flange components. The flange component includes a flange plate 101 and a welded flange. The folded plate on the blue plate 101 is specifically formed by splicing the folded plates to form the bottom flange 1, which is small in size, convenient for the overall hot-dip galvanizing process, and solves the problem of difficult transportation and lifting, as shown in FIG. 5 .

As for the above-mentioned split-type barrel-shaped tower, the barrel wall plate 4 is bent longitudinally at least once, and preferably bent once.

In this embodiment, the tube wall plate 4 is bent once to form a similar circle. Specifically, the tube wall plate 4 is bent into a left tube wall plate 401 and a right tube wall plate 402, and the left tube wall plate 401 and the The angle A between the left connecting plate 201 and the angle B between the right connecting plate 402 and the right connecting plate 202 are both in the range of 80°-90°. The value range of the angle C between the cylinder wall plates 402 is 165°-175°, as shown in FIG. 6 .

In the above-mentioned folded barrel-shaped tower, the connecting end of the folded plate is equipped with a reinforcing rib plate 7 for strengthening the connection with other folded plates, and the inner side of the reinforcing rib plate 7 is also provided with a reinforcing plate 8, The effect of reinforcing plate 8 and the holes on it is to facilitate the installation of accessories in the tower; Another folded plate adjacent to the folded plate on 301 is strengthened and connected, and may also be strengthened and connected with the folded plate on the second section of cylinder 302 above the folded plate, so the reinforcing rib plate 7 is also bent once. The reinforcing ribs 7 play a role in strengthening the connection, because the connecting end of the cylinder body 3 is subject to the largest shear force and is relatively weak, so it is necessary to set the reinforcing ribs 7 to increase its strength. If the stiffener plate 7 is not provided, the thickness of the cylinder wall will be greatly increased, so setting the stiffener plate 7 will save about 3% to 6% of material for the cylinder body, thereby saving costs.

Further, the lengths of the connecting plates 2 on each of the folding plates are approximately equal, which is convenient for rapid production in large quantities. A gap 10 is formed, that is, the connection plate 201 on the cylinder body 3 of the upper section is not in contact with the connection plate 201 on the cylinder body 3 of the next section.

Preferably, as shown in FIG. 10 , one side of the reinforcing plate 8 can pass through the rib plate 7 and enter the gap 10 to be in contact with the connecting plate 2 to form a positioning plate 11 with a positioning function, as shown in FIG. As shown, this method realizes the horizontal and vertical positioning of the connecting plate 2 and is very reliable. Of course, the two adjacent connecting plates 201 on the cylinder 3 can also be made with different lengths, so that the connecting plates 201 on the upper cylinder 3 can be docked with the connecting plates 201 on the next cylinder 3 and connected to the next cylinder. The adjacent connecting plates 201 on the body 3 overlap to realize the positioning function, but this method has the following disadvantages: first, the connecting plates 201 of different lengths need to cut larger slits, which will cause waste of materials and make the manufacturing process more complicated. The second is that this kind of positioning method is not as reliable as the above-mentioned positioning method using the positioning plate 11 after many tests; the third is that this kind of positioning method is only suitable for making a tapered tower, not suitable for making a straight tower .

As for the folded barrel-shaped tower mentioned above, the cylinder body 3 is straight or cone-shaped, and the material of the folded plate is high-quality high-strength steel plate, which is beneficial to the overall hot-dip galvanizing process.

The fabrication and assembly steps of the tower are as follows:

First, cut the steel plate into multiple pieces according to the required size;

Second, use a CNC cutting machine to cut multiple rows of bolt holes of the same size on both sides and the upper and lower ends of the steel plate;

Third, cut out the notch 5 and the semicircular opening 6 on the steel plate;

Fourth, use an 8,000-ton intelligent numerical control forming machine to bend the steel plate into a left connecting plate 201, a right connecting plate 202, a left tube wall plate 401 and a right tube wall plate 402 at a specific angle;

Fifth, welding and fixing the folded plate on the flange plate 101 to form a flange assembly;

Sixth, carry out the overall hot-dip galvanizing process;

Seventh, transport the flange components and multiple folded plates to the construction site;

Eighth, the bottom flange 1 and the single-section cylinder 3 are assembled into the bottom flange 1 and the single-section cylinder 3 through the rib plate 7 and the bolt 9, and finally hoisted and connected to form a complete tower;

In the fourth step, the left connecting plate 201 and the right connecting plate 202 are first bent on both sides of the steel plate, and then bent once in the middle of the tube wall plate 4 to form the left tube wall plate 401 and the right tube wall plate 402, which cannot be reversed. Conducive to the release of stress.

The tower can be used as the casing of large building foundation pits, the casing of large ocean engineering and artificial islands, the tower of large offshore and onshore wind power generators, the tower of ultra-high voltage transmission towers, the tower of urban landscape lighthouses, TV Tower tubes, super-large diameter storage silos for coal, ore, grain, etc., and main columns and main girder casings of various large-scale steel structure buildings, as shown in Figures 11 to 13.

The present invention has been described in detail above with reference to the embodiments of the accompanying drawings, and those skilled in the art can make various changes to the present invention according to the above description. Therefore, some details in the embodiments should not be construed as limiting the present invention, and the present invention will take the scope defined by the appended claims as the protection scope of the present invention.
