The statements herein merely provide background related to the present disclosure and may not necessarily constitute prior art.

With the technology of wind power generation becoming mature day by day and the development of wind resources for many years, most of wind fields of the plain class are developed and finished, and a grid-connected power generation mode is entered. The near phase begins to enter the development of high altitude, low wind speed areas. The tower height also gradually breaches 130 meters from 70 meters.

However, the increase of the height of the tower also corresponds to the sharp increase of the construction cost of the wind field in the mountainous area. The requirements for straightness and gradient of roads in the site are multiplied, and the expenses for road operation, post maintenance and the like in the site are increased along with the increase. And an increase in tower height, also corresponds to an increase in tower diameter. The main transportation mode of the existing tower is road transportation, the limit height of the existing road transportation is usually 5 meters, which means that the diameter of the tower exceeds 4.6 meters, a special transport vehicle is needed to meet the transportation requirement, and along with the increase of the diameter of the tower, the diameter required by the height of the existing tower must reach 6.7 meters to meet the use requirement and the safety performance, and if the traditional tower mode is utilized, the tower cannot reach a wind field. A novel segmented tower is generated, and the tower can be divided into three segments, so that the height of the tower in the transportation process can be reduced, and the transportation requirements can be met. And can be assembled in advance after arriving at the machine position and then hoisted.

The inventor understands that the emerging segmented tower can meet the requirement of on-site road transportation, but new requirements are put on the production of the tower, and the traditional production mode is required to be changed and upgraded. The process of separating the tower is required to be added, and because the tonnage of the tower is heavier, and the requirement of the tower on the flatness of the flange is within the range of 2mm, the flange is not damaged or deformed in the separation process, and the vertical flange in the cylinder is not damaged when the tower is placed after separation, so that the tower cannot collide with the flange. Most of the existing separated tower frame separation tools are fixed, corresponding protective measures cannot be taken during cutting and separation, and the separated tower frame needs to be manufactured with a tool again for supporting.

The working principle is as follows: when the device is used for clamping and positioning the tower before splitting:

the first step is as follows: and (3) assembling, namely assembling the tool after the tower frame finishes a circular seam process, fixing the tool by using the slotted hole and the flange hole on the sliding support plate 6 after the tower frame is integrated, fastening the tool on the flange surface by using bolts at least at 6 points, and needing one tool for each flange. And entering the second step.

Specifically, in the first step, the tool is firstly assembled, the components are tiled on the ground and assembled in advance, the tool can be divided into three pieces (namely three positioning pieces) and consistent with the slicing mode of the corresponding slicing tower, the three slicing tools are spliced into a complete circle, the three slicing tools are connected by using connecting plates and bolts, the connecting plates at the positions of the inner arc plates 5 are connected firstly, and the connecting plates of the outer roller plates 1 are connected after fastening.

After the initial assembly, the bolts are fastened to prevent loosening. And then the sliding support plate 6 is adjusted to a proper position, so that the tool positioning hole (namely the strip-shaped hole 4) on the sliding support plate 6 and the flange hole in the tower are positioned on the same circle of outer diameter. Currently, the outer diameter of a mounting flange hole is determined according to a drawing, and then adjustment is carried out according to scales on a main upright post. After the position is adjusted, the position is fixed by a pin shaft 3. Specifically, the pin shaft 3 penetrates through the side wall of the sliding sleeve and is tightly pressed on the outer wall of the upright post. The relative positions of the sliding bracket and the upright are positions when the first position and the second position are shown in fig. 9 and 10, respectively. Is suitable for towers with different diameter sizes.

The second step is that: and cutting, namely cutting the tower frame into the slicing and cutting process, and cutting the tower frame by using a cutting trolley according to a line drawn in advance, wherein the tower frame is not separated by itself after cutting because the tool is assembled into a whole, and the third step is carried out after all the tower frames are cut.

The third step: the first positioning member 9 is separated. And (3) installing a lifting ring in a round hole in the outer roller plate 1, decomposing the concave-convex structure and the outer roller plate 1, connecting the lifting ring by using a travelling crane, lifting the first positioning piece 9 to separate the tower frame to vertically lift, and entering the fourth step.

The fourth step: and (5) separating. And separating the rest two towers, utilizing the supporting legs 8 to ensure that the two towers are horizontally placed on the ground, and separating the concave-convex structure and the outer roller plate 1 to form two independent tools in a separated state. And then entering the fifth step.

The fifth step: can utilize frock direct contact ground for the continuation circulation of depositing or the subsequent handling of burst pylon, the going on of sanding spraying paint is carried out more easily to this kind of angle.

And a sixth step: and in combination, after the tower reaches a machine position after the tower is produced, the tower can be assembled by utilizing the tool on the segmented tower, and the concave-convex structure can be utilized to quickly position and combine, so that the size of the tower after integration is ensured.
