As shown in fig. 1 to 27, the processing method of the slicing tower of the present embodiment includes a step S10 of processing a tower assembly 10, the tower assembly 10 including a tower body 11 and flanges 12 at both ends of the tower body 11, the flanges 12 including 3 slicing tower flanges 121 connected to each other, a step S20 of cutting the tower body 11 in a longitudinal direction of the tower assembly 10 to divide into 3 slicing tower slices 113 corresponding to the 3 slicing tower flanges 121 one by one, the tower slices 113 and the slicing tower flanges 121 at both ends of the tower slices 113 forming one tower slice assembly 13, adjacent two tower slice assemblies 13 being connected to each other, a step S30 of transporting the tower assembly 10 out of the shop and placing it on an opening tool 90, a step S40 of opening the tower slice assembly 10 by opening the tool 90 and placing the 3 tower slice assemblies 13 on the sand blast tool assembly 100, a step S50 of connecting the tower slice assembly 13 to the sand blast tool assembly 100 and performing a sand blast rust removal operation, a step S60 of transporting the tower slice assembly 13 from the shop to the sand blast tool assembly 70.

After the tower cutting and slicing steps are performed, the tower assembly 10 is integrally moved out of the black tower workshop and opened by opening the tool, so that a plurality of tower slicing assemblies are formed. Each tower segment assembly 13 is then sand blasted through the sand blast derusting tool assembly 100. And then, carrying out corrosion prevention on each tower barrel slicing assembly 13, and finally, transporting the single tower barrel slicing assemblies 13 out of a white tower workshop and transporting to a storage yard. Because the whole process of processing the tower barrel assembly 10 is not connected with a false flange with larger volume, on the basis of not modifying the original factory building and some processing auxiliary equipment, most tower barrel production factories can process the slicing towers, and the popularization and development of the slicing tower barrel technology are facilitated.

In this embodiment, the flange 12 includes 3 pieces of the split tower flange 121 connected to each other, and in other embodiments not shown in the drawings, the number of pieces of the split tower flange 121 may be more than 3.

As shown in fig. 11 to 15, in the present embodiment, step S30 further includes connecting the split tower flange 121 located on the left and right sides of the flange 12 in the radial direction with the opening jig 90, step S40 further includes canceling the connection relationship of the upper tower split assembly 13 with the other tower split assemblies 13 and placing it on the sand blasting jig assembly 100, step S42 canceling the connection relationship of the left and right side tower split assemblies 13 and the connection relationship of the split tower flange 121 of the right side tower split assembly 13 with the opening jig 90 and placing the right side tower split assembly 13 on the sand blasting jig assembly 100, and step S43 canceling the connection relationship of the split tower flange 121 of the left side tower split assembly 13 with the opening jig 90 and placing the left side tower split assembly 13 on the sand blasting jig assembly 100. The structure ensures that the positions of the tower section-piece assemblies 13 at the left side and the right side are kept unchanged when the tower section-piece assemblies 13 at the upper part are lifted, and the lifting of the tower section-piece assemblies 13 at the upper part is not influenced. When the right tower section of thick bamboo subassembly 13 lifts by crane, the position of left tower section of thick bamboo subassembly 13 remains unchanged, does not influence right tower section of thick bamboo subassembly 13 and lifts by crane. Therefore, the steps described above enable the tower assembly 10 to be opened smoothly with high opening efficiency.

It should be noted that, when the number n of the segment tower flanges 121 is greater than 3, at least n-1 segments of the segment tower flanges 121 should be connected to the opening tool 90. In this way, when the tower segment assembly 13 is detached, the tower segment assembly 13 can be kept at a preset position, so that the tower assembly 10 can be opened smoothly.

As shown in fig. 11 to 15, in the present embodiment, in step S40, each tower segment 13 is hoisted to the sand blasting tool assembly 100 by a crane, wherein the hoisting points of the tower segment 13 located at the upper part include four hoisting points located at four corners of the tower segment 13, and the hoisting points of the tower segment 13 located at the left and right sides include four hoisting points located at four corners of the tower segment 13 and one hoisting point located at the middle part of the tower segment 13. The above steps enable the tower segment assembly 13 to be placed stably on the sand blasting tool assembly 100.

As shown in fig. 11 to 15, in the present embodiment, the opening tool 90 includes two first connection plates 52 that are relatively movable in the left-right direction, the tower segment assemblies 13 on the left and right sides are connected to the respective first connection plates 52, and in step S40, after the connection relationship between the tower segment assemblies 13 and the respective first connection plates 52 is canceled, and before the tower segment assemblies 13 are placed on the sand blasting tool assembly 100, the respective first connection plates 52 are moved to the avoidance position where the tower segment assemblies 13 are avoided. The above steps reduce the probability of the tower barrel split assembly 13 striking the first connecting plate 52 when the tower barrel split assembly 13 on the left side and the right side is lifted, and ensure the service life of the opening tool 90.

As shown in fig. 20 to 22, in the present embodiment, the sand blasting and derusting tool assembly 100 includes two second connection plates 140 and a first telescopic device 130 which are oppositely arranged, the step S50 includes a step S51 of connecting two segment tower flanges 121 of the tower segment assembly 13 to the two second connection plates 140 respectively, a step S52 of performing sand blasting and derusting operation on the tower segment 113, a step S53 of canceling the connection relationship between the tower segment assembly 13 and the two second connection plates 140 and moving the tower segment assembly 13 through the first telescopic device 130 to enable the second connection plates 140 to be dislocated with the segment tower flanges 121 of the tower segment assembly 13, and a step S54 of performing sand blasting and derusting operation on the segment tower flanges 121. The steps enable the tower barrel fragments 113 of the tower barrel fragment assembly 13 and the fragment tower flanges 121 at the two ends to be sufficiently subjected to sand blasting and rust removal, so that the processing quality of the tower barrel fragment assembly 13 is ensured.

As shown in fig. 20 to 22, in the present embodiment, step S60 includes a step S61 of paint spraying the segment tower flange 121 of the tower segment 13, a step S62 of moving the tower segment 13 by the first telescopic device 130 so that the second connection plate 140 is opposite to the segment tower flange 121 of the tower segment 13 and reconnected, and a step S63 of paint spraying the tower segment 113 of the tower segment 13. In the above steps, before the corrosion prevention operation (paint spraying) is performed on the tower section assembly 13, the tower section assembly 13 on the sand blasting rust removal tool assembly 100 is directly subjected to the corrosion prevention operation without removing the tower section assembly 13 from the sand blasting rust removal tool assembly 100. The steps are simplified, and the processing efficiency of the tower barrel slicing assembly 13 can be improved.

As shown in fig. 23, in the present embodiment, the second connection plate 140 is rotatably provided, and in step S63, the second connection plate 140 is rotated to a preset position to paint the top and inner side walls of the tower segment 113. The steps enable the top and inner walls of the tower segment 113 to be uniformly coated with paint, and ensure the processing quality of the tower segment assembly 13.

As shown in fig. 25, in the present embodiment, step S10 includes a step S11 of splicing 3 pieces of the split tower flange 121 into flanges 12, a step S13 of welding the flanges 12 to both ends of the tower body 11, a step S15 of positioning and welding a plurality of longitudinal flanges 14 to the inner side wall of the tower body 11, and a step S16 of welding the tower inner part to the inner side wall of the tower body 11.

In the present embodiment, as shown in fig. 25, between step S11 and step S13, step S10 further includes a step S12 of welding the multi-segment shell ring 15 together to form the tower body 11. The length of the processed slicing tower can be adjusted according to actual needs.

In this embodiment, between step S13 and step S15, step S10 further includes a step S14 of welding all girth welds inside and outside. The processing quality of the slicing tower can be improved through the steps.

As shown in fig. 25 to 27, the tower assembly 10 actually includes a tower body 11 and two flanges 12 disposed at two ends of the tower body 11, wherein the tower body 11 is formed by welding a plurality of shell segments 15, and the flanges 12 are formed by splicing three split tower flanges 121. Three pairs of longitudinal flanges 14 are arranged in the tower barrel, and the three pairs of longitudinal flanges 14 are respectively opposite to the splicing seams of the three segmented tower flanges 121. The tower is sliced along the midline of each pair of longitudinal flanges 14 to divide the tower body 11 into three tower slices 113. Each tower segment 113 forms a set of tower segment assemblies 13 with two segment tower flanges 121 at each end.

The following describes the specific structure of the opening tool 90:

As shown in fig. 1, 2, 5, 6 and 11 to 15, the opening tool comprises a plurality of roller frames 40 and two fixing brackets 50. The plurality of roller frames 40 are arranged at intervals along the preset direction w and support the tower body 11. The two fixing brackets 50 are arranged at intervals along the preset direction w and are positioned on the outer sides of the roller frames 40 in the preset direction w, the fixing brackets 50 comprise a first bracket body 51 and two first connecting plates 52 arranged on the first bracket body 51, and each first connecting plate 52 is correspondingly connected with different fragment tower flanges 121.

When the tower is required to be opened, the tower is firstly placed on the plurality of roller frames 40, and the three tower segment assemblies 13 are respectively an upper tower segment assembly, a left tower segment assembly and a right tower segment assembly. Then, the split tower flanges 121 (i.e., the left split tower flange and the right split tower flange) of the left and right split tower assemblies 13 at one end of the tower are respectively connected with the two first connection plates 52 of the fixing bracket 50 at the corresponding side. Next, the split tower flanges 121 of the left and right tower split assemblies 13 at the other end of the tower are connected to the two first connection plates 52 of the corresponding one-side fixing brackets 50, respectively. Then, the connection relation between the longitudinal flange 14 of the upper tower barrel splitting assembly and other longitudinal flanges 14 is canceled, and the upper tower barrel splitting assembly is lifted to the sand blasting derusting tool assembly through a crane. Then, the connection relation between the longitudinal flange 14 of the right tower section of thick bamboo burst assembly and the longitudinal flange 14 of the left tower section of thick bamboo burst assembly is canceled, and the burst tower flange 121 of the right tower section of thick bamboo burst assembly is detached from the first connecting plate 52, and the right tower section of thick bamboo burst assembly is lifted to the sand blasting derusting tool assembly through a crane. Because the segment tower flange 121 of the left tower segment assembly is still connected to the first connecting plate 52, the position of the left tower segment assembly is not changed during the process of hanging the right tower segment assembly, so that the tower can be smoothly opened. Finally, the segment tower flange 121 of the left tower segment assembly is detached from the first connecting plate 52, and the left tower segment assembly is lifted to the sand blasting rust removing tool assembly through a crane, so that the aim of opening the whole tower is fulfilled. The structure enables the tower barrel to be opened smoothly under the condition that no false flange exists, so that most tower barrel production factories can process the slicing towers, and popularization and development of the slicing tower barrel technology are facilitated.

The upper fragment tower flange located on the upper side among the plurality of fragment tower flanges 121 is not connected to any of the first connection plates 52. When the left tower section of thick bamboo burst subassembly is hung to the lift-off, because left and right burst tower flange all is connected with first connecting plate 52, the position of left and right tower section of thick bamboo burst subassembly can not change. In addition, the opening process is to suspend the right tower section of thick bamboo burst subassembly first and then suspend the left tower section of thick bamboo burst subassembly, and in other embodiments not shown in the figure, the left tower section of thick bamboo burst subassembly may also be suspended first and then suspend the right tower section of thick bamboo burst subassembly. In addition, when the left tower section of thick bamboo burst subassembly about lifting, need increase the hoisting point in tower section of thick bamboo burst subassembly middle part.

Specifically, after the splitting tower flange 121 of the tower splitting assembly is detached from the corresponding first connecting plate 52, the first connecting plate 52 can slide away from the tower splitting assembly, and then the tower splitting assembly is lifted off, so that the phenomenon that the tower splitting assembly impacts the fixing support 50 when the tower splitting assembly is lifted off is avoided as much as possible, and the service life of the opening tool is guaranteed.

As shown in fig. 1, 6 to 9, 12 and 14, the first bracket body 51 is provided with a first chute 511 extending along the direction x, the first connecting plate 52 includes a plate body 521 and a connecting rod 522 connected to the plate body 521, and the first fastener 60 is disposed through the bottom of the connecting rod 522 and the first chute 511. The structure is simple, on one hand, the connection stability and the reliability are strong, and on the other hand, the adjustment of staff is convenient.

As shown in fig. 1, 2, 12 and 14, a first handle 53 is provided on the first connection plate 52. The above structure facilitates the movement of the first connection plate 52 by the worker, improving the use experience.

As shown in fig. 1, 4 and 10, the opening tool further comprises a plurality of auxiliary brackets 70. The plurality of auxiliary brackets 70 are arranged at intervals along the preset direction w and are positioned between the two fixed brackets 50, the auxiliary brackets 70 comprise a second bracket body 71 and a plurality of opposite supporting plates 72 slidably arranged on the second bracket body 71 along the direction x, and the supporting plates 72 support the tower body 11. In particular, the auxiliary support 70 is placed in the middle of the turret to provide auxiliary support, preventing the turret from being undesirably removed due to excessive deformation during the entire opening process. In addition, the auxiliary bracket 70 is arranged in a sliding manner, so that the probability of collision with the auxiliary bracket 70 is reduced in the process of lifting the tower barrel slicing assembly, and the service life of the auxiliary bracket 70 is ensured.

As shown in fig. 1 and 4, the upper surface of the support plate 72 is a cambered surface 721 that is adapted to the outer surface of the tower body 11. The structure can better play a role in auxiliary support.

As shown in fig. 1 and 4, the auxiliary bracket 70 further includes a second handle 73 provided on the support plate 72. The above structure facilitates the movement of the support plate 72 by the worker, improving the use experience.

As shown in fig. 1 and 10, the second bracket body 71 is provided with a second chute 711 extending along the direction x, the support plate 72 is connected to the second bracket body 71 by a second fastening member 80, and the second fastening member 80 is disposed through the bottom of the support plate 72 and the second chute 711. The structure is simple, on one hand, the connection stability and the reliability are strong, and on the other hand, the adjustment of staff is convenient.

The following describes in detail the specific structure of the sand blasting assembly 100:
