The diameter of the lower cylindrical structure is larger than that of the upper cylindrical structure. A maintenance door opening is arranged on the lower cylindrical structure. A ventilation window opening and a driver room opening are arranged on the middle conical structure. An air inlet window opening is arranged on the upper cylindrical structure. Reinforcing rings and reinforcing longitudinal bars are welded on the inner surface of the tower body.

[0011] The above method, when it is found that the lower part of the tower body cannot be installed on the rotary platform, forms a frame structure on one side and the other side of the tower body through two first supports and two second supports, and enables the height of the first support and the second support to reach the height of the cutting area, so as to facilitate the operator to split the tower body, then hoist the upper part of the tower body to the resting station to cut the groove, facilitate the reliable butt joint with the lower part of the tower body to be butt jointed, and remove the lower part of the tower body which does not meet the assembly requirements, realize the reuse of the local material of the tower body, and reduce the use cost; then move the two first supports and the two second supports to the periphery of the lower part of the tower body to be butt jointed to form a frame, and enable the height of the first support and the second support to reach the height of the upper end of the lower part of the tower body to be butt jointed, then weld through the first support and the second support, move the first support and the second support which are assembled in advance outside the tower body, so that the maneuverability of the operation is stronger, the process of splitting and reassembling the tower body can be effectively accelerated, and the assembly height can be reliably ensured, thereby improving the operation efficiency, saving time and manpower, enabling the reassembled tower body to meet the assembly requirements, and welding the fixing piece on the side of the upper part of the tower body before cutting, which can reduce the influence on the upper part of the tower body in the cutting process, thereby enabling the reliability of the connection between the upper part of the tower body and the lower part of the tower body to be butt jointed.

[0012] Further, the step S1 comprises S1.1~ S1.5,

[0013] S1.1 measures the distance from the upper end face of the sealing plate to the lower end face in the tower body, and then measures the distance from the lower end face of the sealing plate to the upper end face of the bottom plate of the lower part of the tower body;

[0014] S1.2 sets a mark line one and a mark line two horizontally on the outer side of the tower body, so that the distance from the mark line one to the upper end face of the bottom plate of the lower part of the tower body is equal to the distance from the lower end face of the sealing plate to the upper end face of the bottom plate of the lower part of the tower body, and the distance from the mark line two to the mark line one is equal to the distance from the upper end face of the sealing plate to the lower end face;

[0015] S1.3 sets a center line horizontally between the mark line one and the mark line two, so that the distance from the mark line one to the center line is equal to the distance from the mark line two to the center line, and then sets a mark line three horizontally in the range from one fourth of the distance from the mark line one to the center line to one half of the distance from the mark line one to the center line, and sets a mark line four horizontally in the range from one fourth of the distance from the mark line two to the center line to one half of the distance from the mark line two to the center line;

[0016] S1.4 determines the area between the mark line three and the mark line four as a cutting area;

[0017] S1.5weld the clamping plate at the lower end of the sealing plate, so that the clamping plate is connected with the sealing plate to form an integral body, then determine the cutting end face on the sealing plate, and cut the sealing plate along the cutting end face, so that the root is formed between the cutting end face and the inner side surface of the tower body after cutting, and the clamping plate and the sealing plate are removed after cutting.

[0018] The above arrangement determines the position of the sealing plate outside the tower body, thereby determining the cutting area outside the tower body, facilitating subsequent cutting of the tower body, and reserving the root during cutting of the sealing plate to prevent damage to the inner side of the upper part of the tower.

[0019] Further, the step S2 further comprises:

[0020] Before lifting, the first gantry and the second gantry are assembled, and the support seats are welded at the bottom of the first gantry and the second gantry respectively; the two second gantries are lifted to one side of the lower part of the tower body, and the two second gantries are aligned in the direction perpendicular to the horizontal line, then the two first gantries are lifted to the other side of the lower part of the tower body, and the two first gantries are aligned in the direction perpendicular to the horizontal line,

[0021] After the two second gantries are aligned, the support seats of the second gantries are fixed, then the connecting pieces are installed at the bottom of the two second gantries, and the connecting plates are installed at the top of the two second gantries, so that the two second gantries form an integral body through the connecting pieces and the connecting plates after connection;

[0023] The above arrangement ensures that the two first gantries and the two second gantries are at the same height by aligning the two first gantries and the two second gantries in the direction perpendicular to the horizontal line, facilitating the movement of the first gantry and the second gantry to the outside of the tower body, thereby facilitating the walking operation of the workers between the first gantry and the second gantry, saving time and improving the operation efficiency.

[0024] Further, the step S3 further comprises:

[0025] The fixing pieces are sequentially welded on the outer side surface of the upper part of the tower body, then the fixing pieces are welded between them, so that the fixing pieces on the outer side surface of the upper part of the tower body form an integral body fixed on the outer side surface of the upper part of the tower body, before carbon planing cutting, the crane is controlled to make the steel wire rope for lifting the tower body in a taut state, then the circular carbon rod and the flat carbon rod are used to perform carbon planing cutting in a clockwise direction around the tower body in the cutting area on the outer side surface of the tower body.

[0027] Further, the step S4 further comprises:

[0028] The connecting pieces and connecting plates between the two first racks, between the two second racks, and between the first and second racks are removed, and then the first and second racks are removed in sequence.

[0030] Further, the step S4 further comprises:

[0031] The slope is opened on the upper part of the tower body at the end of the carbon planer cutting, and the slope is inclined to the carbon planer cutting surface, and the inclination angle between the slope and the carbon planer cutting surface is 30°-50°.

[0032] The above arrangement facilitates the upper part of the tower body to be connected to the lower part of the tower body to be connected through the slope.

[0033] Further, the step S4 further comprises:

[0034] If the carbon planer cutting end of the upper part of the tower body after splitting is damaged and cannot be opened with a slope, a marking line five is horizontally arranged on the outer side of the upper part of the tower body within a range of 400-600 mm from the carbon planer cutting surface, and carbon planer cutting is performed at the marking line five, and the slope is opened after cutting.

[0035] The above arrangement facilitates removing the unqualified carbon planer cutting end of the upper part of the tower body after splitting, and then connecting the upper part to the lower part of the tower body to be connected.

[0036] Further, the step S5 further comprises:

[0037] In the step S4, the upper part of the tower body with the opened slope is lifted to above the connection position, the upper part of the tower body is aligned with the lower part of the tower body to be connected on the same axis, and the upper part of the tower body is moved downward along the axis direction, and the work of the crane is stopped when the slope of the upper part of the tower body abuts against the upper end of the lower part of the tower body to be connected.

[0038] The above arrangement can align the upper part of the tower body with the opened slope with the lower part of the tower body to be connected, thereby facilitating welding at the slope.

[0039] Further, the step S5 further comprises

[0040] After the two second stands are aligned, the support bases of the second stands are fixed, then connecting pieces are installed at the bottom of the two second stands, and connecting plates are installed at the top of the two second stands, so that the two second stands are connected to form an integrated body through the connecting pieces and the connecting plates;

[0042] After the two first stands are aligned, the support bases of the first stands are fixed, then connecting pieces are installed at the bottom of the two first stands, and connecting plates are installed at the top of the two first stands, so that the two first stands are connected to form an integrated body through the connecting pieces and the connecting plates, then connecting pieces and connecting plates are respectively installed at the bottom and the top of the first stand and the second stand on the same side, so that the two first stands and the second stand are connected to form an integrated body through the connecting pieces and the connecting plates, thereby improving the stability.

[0043] The above arrangement can ensure that the two first stands and the two second stands are at the same height, the bottom of the first stand and the second stand is fixed by the connecting piece, and the connecting plate fills the gap between the top of the first stand and the second stand, thereby facilitating the movement of the workers between the first stand and the second stand for work.

[0044] Further, the step S5 further comprises:
