Description

Technical Field

[0001] The invention relates to the field of slice towers, and in particular to a processing method of a slice tower. Background Art

[0002] As a single wind turbine generator set develops towards large-scale development, it means that a single wind turbine generator set needs to absorb more wind energy. As an important supporting structure of the generator set, the tower tube bears an increasingly large load. The increase in wind turbine load causes the bottom diameter of the tower to become larger and larger, making transportation more difficult. In order to solve the transportation problem, the main wind power unit has developed a segmented tower, that is, the tower that is difficult to transport is divided into segments, transported to the site in segments, and then assembled into a complete tower by bolting the longitudinal flanges of the segmented tower tubes.

[0003] The existing production process basically adopts the method of false flange for production. The cylinder is placed on the roller frame through the false flange. The roller frame drives the cylinder to rotate through the false flange to cut the tower into pieces. After the slice cutting, due to the existence of the false flange, the entire cylinder can be sanded and the surface can be anti-corrosive. Then the anti-corrosion white tower can be taken out of the white tower workshop as a whole, and then opened into pieces and placed in the yard. However, the diameter of the false flange is often more than 8.5 meters, so the size of the general tower plant and related auxiliary equipment such as roller frames cannot meet the production requirements at all. At the same time, since wind power projects often have tight delivery periods, there is often no time to renovate the plant for the sliced ​​tower. Therefore, this situation seriously hinders the development of the sliced ​​tower. Summary of the invention

[0004] The main purpose of the present invention is to provide a method for processing a slice tower to solve the problem in the prior art that the processing of the slice tower has extremely high requirements on the size of the plant.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a method for processing a segmented tower, comprising: step S10: processing a tower assembly, the tower assembly comprising a tower body and flanges located at both ends of the tower body, the flanges comprising n segmented tower flanges connected to each other; step S20: cutting the tower body along the longitudinal direction of the tower assembly to divide it into n tower segments corresponding to the n segmented tower flanges one by one, the tower segments and the segmented tower flanges located at both ends of the tower segments forming a tower segment assembly, and two adjacent tower segment assemblies The parts are connected to each other; step S30: transport the tower assembly out of the workshop and place it on the opening tooling; step S40: open the tower assembly by opening the tooling, and place n tower segment assemblies on the sandblasting and rust removal tooling assemblies respectively; step S50: connect the tower segment assembly to the sandblasting and rust removal tooling assembly, and perform sandblasting and rust removal operation; step S60, perform anti-corrosion operation on the tower segment assembly; step S70: remove the tower segment assembly from the sandblasting and rust removal tooling assembly, and transport the tower segment assembly to the yard.

[0006] In one embodiment, step S30 also includes: connecting the slice tower flanges on the left and right sides in the radial direction of the flange to the opening tooling; step S40 also includes: step S41: canceling the connection relationship between the upper tower slice assembly and other tower slice assemblies, and placing it on the sandblasting and rust removal tooling assembly; step S42: canceling the connection relationship between the tower slice assemblies on the left and right sides, as well as the connection relationship between the slice tower flange of the tower slice assembly on the right and the opening tooling, and placing the tower slice assembly on the right on the sandblasting and rust removal tooling assembly; step S43: canceling the connection relationship between the slice tower flange of the tower slice assembly on the left and the opening tooling, and placing the tower slice assembly on the left on the sandblasting and rust removal tooling assembly.

[0007] In one embodiment, in step S40, each tower segment assembly is lifted by a crane and transported to the sandblasting and rust removal tooling assembly, wherein the lifting points of the upper tower segment assembly include four lifting points at the four corners of the tower segment assembly, and the lifting points of the tower segment assemblies on the left and right sides include four lifting points at the four corners of the tower segment assembly and one lifting point in the middle of the tower segment assembly.

[0008] In one embodiment, the opening tooling includes two first connecting plates that are relatively movable in the left and right directions, and the tower segment assemblies on the left and right sides are connected to the corresponding first connecting plates. In step S40, after canceling the connection relationship between the tower segment assembly and the corresponding first connecting plate, and before placing the tower segment assembly on the sandblasting and rust removal tooling assembly, the corresponding first connecting plate is moved to an avoidance position to avoid the tower segment assembly.

[0009] In one embodiment, the sandblasting and rust removal tooling assembly includes two second connecting plates and a first telescopic device arranged relatively to each other, and step S50 includes: step S51: respectively connecting the two segmented tower flanges of the tower segment assembly to the two second connecting plates; step S52: performing sandblasting and rust removal operations on the tower segments; step S53: canceling the connection relationship between the tower segment assembly and the two second connecting plates, and moving the tower segment assembly through the first telescopic device to misalign the second connecting plates and the segmented tower flanges of the tower segment assembly; step S54: performing sandblasting and rust removal operations on the segmented tower flanges.

[0010] In one embodiment, step S60 includes: step S61: spraying paint on the slice tower flange of the tower slice assembly; step S62: moving the tower slice assembly through the first telescopic device so that the second connecting plate is opposite to the slice tower flange of the tower slice assembly, and reconnecting; step S63: spraying paint on the tower slices of the tower slice assembly.

Each piece of the tower tube slicing assembly is then sandblasted and rust-removed by the sandblasting and rust-removing tooling assembly. Each piece of the tower tube slicing assembly is then subjected to corrosion protection, and finally the single-piece tower tube slicing assembly is transported out of the white tower workshop and transported to the yard. Since no large false flange is connected during the entire process of processing the tower tube assembly, most tower tube production plants can process slicing towers without rectifying the original factory buildings and some auxiliary processing equipment, which is conducive to the promotion and development of slicing tower technology.

[0050] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0051] like Figures 1 to 27 As shown, the processing method of the segmented tower of this embodiment includes: step S10: processing a tower assembly 10, the tower assembly 10 includes a tower body 11 and flanges 12 located at both ends of the tower body 11, the flanges 12 include three segmented tower flanges 121 connected to each other; step S20: cutting the tower body 11 along the longitudinal direction of the tower assembly 10 to divide it into three tower segments 113 corresponding to the three segmented tower flanges 121 one by one, the tower segments 113 and the segmented tower flanges 121 located at both ends of the tower segments 113 form a tower segmented assembly 13, and two adjacent tower segmented assemblies 113 are connected to each other. 3 are connected to each other; step S30: transport the tower assembly 10 out of the workshop and place it on the opening tooling 90; step S40: open the tower assembly 10 by opening the tooling 90, and place the three tower segment assemblies 13 on the sandblasting and rust removal tooling assemblies 100 respectively; step S50: connect the tower segment assembly 13 with the sandblasting and rust removal tooling assemblies 100, and perform sandblasting and rust removal operations; step S60, perform anti-corrosion operations on the tower segment assembly 13; step S70: remove the tower segment assembly 13 from the sandblasting and rust removal tooling assemblies 100, and transport the tower segment assembly 13 to the yard.

[0052] By applying the technical solution of the present embodiment, after the tower tube cutting and slicing step is performed, the tower tube assembly 10 is moved out of the black tower workshop as a whole and opened by opening the tooling to form a multi-piece tower tube slicing assembly. Then, each piece of the tower tube slicing assembly 13 is blasted and rust-removed by the sandblasting and rust-removing tooling assembly 100. Then, each piece of the tower tube slicing assembly 13 is subjected to corrosion protection, and finally the single-piece tower tube slicing assembly 13 is transported out of the white tower workshop and transported to the storage yard. Since a larger false flange is no longer connected during the whole process of processing the tower tube assembly 10, most tower tube production plants can process slicing towers without rectifying the original factory buildings and some processing auxiliary equipment, which is conducive to the promotion and development of slicing tower technology.

[0053] It should be noted that, in the present embodiment, the flange 12 includes three segmented tower flanges 121 connected to each other. In other embodiments not shown in the figure, the number of segmented tower flanges 121 may be more than three.

[0054] like Figures 11 to 15As shown, in the present embodiment, step S30 also includes: connecting the slice tower flanges 121 located on the left and right sides in the radial direction of the flange 12 with the opening tooling 90; step S40 also includes: step S41: canceling the connection relationship between the upper tower slice assembly 13 and other tower slice assemblies 13, and placing it on the sandblasting and rust removal tooling assembly 100; step S42: canceling the connection relationship between the tower slice assemblies 13 on the left and right sides, as well as the connection relationship between the slice tower flange 121 of the tower slice assembly 13 on the right and the opening tooling 90, and placing the tower slice assembly 13 on the right on the sandblasting and rust removal tooling assembly 100; step S43: canceling the connection relationship between the slice tower flange 121 of the tower slice assembly 13 on the left and the opening tooling 90, and placing the tower slice assembly 13 on the left on the sandblasting and rust removal tooling assembly 100. The above structure allows the positions of the tower segment assemblies 13 on the left and right sides to remain unchanged when the upper tower segment assembly 13 is lifted, without affecting the lifting of the upper tower segment assembly 13. When the right tower segment assembly 13 is lifted, the position of the left tower segment assembly 13 remains unchanged, without affecting the lifting of the right tower segment assembly 13. Therefore, the above steps allow the tower assembly 10 to be opened smoothly with high opening efficiency.

[0055] It should be noted that when the number n of the segmented tower flanges 121 is greater than 3, at least n-1 segmented tower flanges 121 should be connected to the opening tool 90. In this way, during disassembly, the tower segmented components 13 that have not been disassembled can be kept in the preset position, so that the tower assembly 10 can be opened smoothly.

[0056] like Figures 11 to 15 As shown, in this embodiment, in step S40, each tower segment assembly 13 is hoisted to the sandblasting and rust removal tooling assembly 100 by a crane, wherein the hoisting points of the tower segment assembly 13 located at the top include four hoisting points located at the four corners of the tower segment assembly 13, and the hoisting points of the tower segment assembly 13 located at the left and right sides include four hoisting points located at the four corners of the tower segment assembly 13 and one hoisting point located in the middle of the tower segment assembly 13. The above steps enable the tower segment assembly 13 to be stably placed on the sandblasting and rust removal tooling assembly 100.

[0057] like Figures 11 to 15As shown, in this embodiment, the opening tool 90 includes two first connecting plates 52 that can move relatively in the left and right directions, and the tower segment assemblies 13 on the left and right sides are connected to the corresponding first connecting plates 52. In step S40, after canceling the connection relationship between the tower segment assemblies 13 and the corresponding first connecting plates 52, and before placing the tower segment assemblies 13 on the sandblasting and rust removal tool assembly 100, the corresponding first connecting plates 52 are moved to the avoidance position of the tower segment assemblies 13. The above steps reduce the probability of the tower segment assemblies 13 hitting the first connecting plates 52 when lifting the tower segment assemblies 13 on the left and right sides, thereby ensuring the service life of the opening tool 90.

[0058] like Figure 20 to Figure 22 As shown, in this embodiment, the sandblasting and rust removal tooling assembly 100 includes two second connecting plates 140 and a first telescopic device 130 arranged relatively to each other, and step S50 includes: step S51: connecting the two segmented tower flanges 121 of the tower segment assembly 13 to the two second connecting plates 140 respectively; step S52: performing sandblasting and rust removal operation on the tower segment 113; step S53: canceling the connection relationship between the tower segment assembly 13 and the two second connecting plates 140, and moving the tower segment assembly 13 through the first telescopic device 130 so that the second connecting plate 140 and the segmented tower flange 121 of the tower segment assembly 13 are misaligned; step S54: performing sandblasting and rust removal operation on the segmented tower flange 121. The above steps enable the tower segments 113 of the tower segment assembly 13 and the segmented tower flanges 121 at both ends to be fully sandblasted and rust removed, thereby ensuring the processing quality of the tower segment assembly 13.

[0059] like Figure 20 to Figure 22 As shown, in this embodiment, step S60 includes: step S61: spraying paint on the segmented tower flange 121 of the tower segment assembly 13; step S62: moving the tower segment assembly 13 through the first telescopic device 130 so that the second connecting plate 140 is opposite to the segmented tower flange 121 of the tower segment assembly 13, and reconnecting; step S63: spraying paint on the tower segment 113 of the tower segment assembly 13. In the above steps, before performing the anti-corrosion operation (spraying paint) on the tower segment assembly 13, it is not necessary to remove the tower segment assembly 13 from the sandblasting and rust removal tooling assembly 100, and the anti-corrosion operation can be directly performed on the tower segment assembly 13 on the sandblasting and rust removal tooling assembly 100. The above steps are simplified, which can improve the processing efficiency of the tower segment assembly 13.

[0060] like Fig.23As shown, in this embodiment, the second connecting plate 140 is rotatably arranged, and in step S63, the second connecting plate 140 is rotated to a preset position to spray paint on the top and inner wall of the tower segment 113. The above steps enable the top and inner wall of the tower segment 113 to be evenly sprayed with paint, thereby ensuring the processing quality of the tower segment assembly 13.

[0061] like Fig.25 As shown, in this embodiment, step S10 includes: step S11: splicing three segmented tower flanges 121 into flanges 12; step S13: welding the flanges 12 to both ends of the tower body 11; step S15: positioning and welding multiple longitudinal flanges 14 to the inner wall of the tower body 11; step S16: welding the tower internal components to the inner wall of the tower body 11.

[0062] like Fig.25 As shown, in this embodiment, between step S11 and step S13, step S10 further includes: step S12: welding multiple cylinder sections 15 together to form the tower body 11. The above steps enable the length of the processed segmented tower to be adjusted according to actual needs.

[0063] In this embodiment, between step S13 and step S15, step S10 further includes: step S14: welding all the circumferential welds inside and outside. The above steps can improve the processing quality of the segmented tower.

[0064] It should be noted that if Figure 25 to Figure 27 As shown, the tower assembly 10 actually includes a tower body 11 and two flanges 12 arranged at both ends of the tower body 11, wherein the tower body 11 is welded by a plurality of cylinder segments 15, and the flange 12 is composed of three segmented tower flanges 121. Three pairs of longitudinal flanges 14 are arranged inside the tower, and the three pairs of longitudinal flanges 14 are respectively opposite to the joint seams of the three segmented tower flanges 121. The tower is segmented along the center line of each pair of longitudinal flanges 14, so that the tower body 11 is divided into three tower segments 113. Each tower segment 113 and the two segmented tower flanges 121 at both ends thereof form a set of tower segment assemblies 13.

[0065] The following is a detailed introduction to the specific structure of opening tooling 90:

[0066] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figures 11 to 15As shown, the opening tooling includes: a plurality of roller frames 40 and two fixed brackets 50. The plurality of roller frames 40 are arranged at intervals along a preset direction w and support the tower body 11. The two fixed brackets 50 are arranged at intervals along a preset direction w and are located outside the plurality of roller frames 40 in the preset direction w. The fixed bracket 50 includes a first bracket body 51 and two first connecting plates 52 arranged on the first bracket body 51. Each first connecting plate 52 is connected to a different segmented tower flange 121.

[0067] When the tower needs to be opened, the tower is first placed on a 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 segment tower flanges 121 (i.e., the left segment tower flange and the right segment tower flange) of the left and right tower segment assemblies 13 at one end of the tower are respectively connected to the two first connecting plates 52 of the fixed bracket 50 on the corresponding side. Next, the segment tower flanges 121 of the left and right tower segment assemblies 13 at the other end of the tower are respectively connected to the two first connecting plates 52 of the fixed bracket 50 on the corresponding side. Then, the connection relationship between the longitudinal flange 14 of the upper tower segment assembly and the other longitudinal flanges 14 is cancelled, and the upper tower segment assembly is hoisted to the sandblasting and rust removal tooling assembly by a crane. Next, cancel the connection relationship between the longitudinal flange 14 of the right tower segment assembly and the longitudinal flange 14 of the left tower segment assembly, and remove the segment tower flange 121 of the right tower segment assembly from the first connecting plate 52, and hoist the right tower segment assembly to the sandblasting and rust removal tooling assembly by a crane. Since 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 will not change during the hoisting of the right tower segment assembly, so that the tower can be opened smoothly. Finally, remove the segment tower flange 121 of the left tower segment assembly from the first connecting plate 52, and hoist the left tower segment assembly to the sandblasting and rust removal tooling assembly by a crane, and the purpose of opening the entire tower is completed. The above structure enables the tower to be opened smoothly by opening the tooling without a false flange, so that most tower production plants can process the segment tower, which is conducive to the promotion and development of the segment tower technology.

[0068] It should be noted that the upper segmented tower flange located on the upper side of the multi-slice tower flange 121 is not connected to any first connecting plate 52. When the left tower segmented assembly is hoisted away, since the left and right segmented tower flanges are both connected to the first connecting plate 52, the positions of the left and right tower segmented assemblies will not change. In addition, the above-mentioned opening process is to first hoist the right tower segmented assembly and then the left tower segmented assembly. In other embodiments not shown in the figure, the left tower segmented assembly can also be hoisted first, and then the right tower segmented assembly. In addition, when hoisting the left and right tower segmented assemblies, it is necessary to add a hoisting point in the middle of the tower segmented assembly.

[0069] like Figure 1 , Figures 6 to 9 , Fig.12 and Fig.14 As shown, a plurality of first connecting plates 52 are arranged at intervals along a direction x perpendicular to a preset direction w, and the first connecting plates 52 are slidably disposed on the first bracket body 51, and the first connecting plates 52 are connected to the first bracket body 51 through a first fastener 60. Specifically, after the tower segment flange 121 of the tower segment assembly is removed from the corresponding first connecting plate 52, the first connecting plate 52 can be slid away from the tower segment assembly, and then the tower segment assembly can be lifted off. The above structure avoids the phenomenon that the tower segment assembly hits the fixed bracket 50 when the tower segment assembly is lifted off, thereby ensuring the service life of the opening tooling.

[0070] like Figure 1 , Figures 6 to 9 , Fig.12 and Fig.14 As shown, the first bracket body 51 is provided with a first slide groove 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 passed through the bottom of the connecting rod 522 and the first slide groove 511. The above structure is simple, and on the one hand, the connection stability and reliability are strong, and on the other hand, it is convenient for the staff to adjust.

[0071] like Figure 1 , Figure 2 , Fig.12 and Fig.14 As shown, a first handle 53 is provided on the first connecting plate 52. The above structure facilitates the staff to move the first connecting plate 52, thereby improving the user experience.

[0072] like Figure 1 , Figure 4 and Fig.10 As shown, the opening tooling also includes: a plurality of auxiliary brackets 70. The plurality of auxiliary brackets 70 are arranged at intervals along a preset direction w and are located between two fixed brackets 50. The auxiliary bracket 70 includes a second bracket body 71 and a plurality of relative support plates 72 slidably arranged on the second bracket body 71 along a direction x, and the support plates 72 support the tower body 11. Specifically, the auxiliary bracket 70 is placed in the middle of the slicing tower to play an auxiliary supporting role, thereby preventing the longitudinal flange of the slicing tower from being difficult to remove due to excessive deformation during the entire opening process. In addition, the auxiliary bracket 70 is slidably arranged to reduce the probability of collision with the auxiliary bracket 70 during the process of lifting the tower slicing assembly, thereby ensuring the service life of the auxiliary bracket 70.

[0073] like Figure 1 and Figure 4As shown, the upper surface of the support plate 72 is a curved surface 721 adapted to the outer surface of the tower body 11. The above structure can better play the role of auxiliary support.

[0074] like Figure 1 and Figure 4 As shown, the auxiliary bracket 70 further includes a second handle 73 disposed on the support plate 72. The above structure facilitates the staff to move the support plate 72, thereby improving the user experience.

[0075] like Figure 1 and Fig.10 As shown, the second bracket body 71 is provided with a second slide groove 711 extending along the direction x, and the support plate 72 is connected to the second bracket body 71 through a second fastener 80, and the second fastener 80 is passed through the bottom of the support plate 72 and the second slide groove 711. The above structure is simple, and on the one hand, the connection stability and reliability are strong, and on the other hand, it is convenient for the staff to adjust.

[0076] The specific structure of the sandblasting and rust removal tooling assembly 100 is described in detail below:

[0077] like Figures 16 to 23 As shown, the sandblasting and rust removal tool assembly 100 includes two sandblasting and rust removal tools 180 arranged at intervals, and the sandblasting and rust removal tool 180 includes a base 110, a first telescopic device 130 and a second connecting plate 140. The first telescopic device 130 is arranged on the base 110, and the first telescopic device 130 has a supporting surface 131 for supporting the tower segment assembly 13. The second connecting plate 140 is arranged on the base 110, and a connecting structure connected to the segment tower flange 121 of the tower segment assembly 13 is provided on the second connecting plate 140. The two segment tower flanges 121 of the tower segment assembly 13 are respectively connected to the second connecting plates 140 of the two sandblasting and rust removal tools 180.

[0078] When the sandblasting and rust removal process is required, the four corners of the tower segment assembly 13 are first placed on the support surface 131 of the first telescopic device 130, and then the first telescopic device 130 is moved until the second connecting plate 140 is opposite to the segment tower flange 121. Then, the second connecting plate 140 is connected to the segment tower flange 121 through the connecting structure. After the connection is completed, the tower segment assembly 13 can be sandblasted and rust-removed. After the sandblasting and rust removal is completed, since the second connecting plate 140 is connected to the segment tower flange 121, the fitting surface of the segment tower flange 121 and the second connecting plate 140 is not sandblasted and rust-removed. In order to fully sandblast and derust the entire tower segment assembly 13, the connection between the second connecting plate 140 and the segment tower flange 121 is cancelled, and the first telescopic device 130 is driven to move so that the segment tower flange 121 and the second connecting plate 140 are mutually offset. At this time, the surface of the segment tower flange 121 that has not been sandblasted and derusted can be sandblasted and derusted. The above structure enables the tower segment assembly 13 to be sandblasted and derusted in all directions, so that the sandblasting and derusting effect of the tower segment assembly 13 is good.

[0079] Since the tower segment assembly 13 is large in size and high in height, it is difficult for the staff to process the top of the outer surface of the tower segment (spraying paint, anti-corrosion), which affects the processing effect of the tower segment assembly 13. Fig.19 and Fig.23 As shown, the second connecting plate 140 is pivotally arranged on the base 110. When the staff processes the top of the outer surface of the tower segment, the second connecting plate 140 is first rotated to a certain angle, so that the tower segment assembly 13 connected to the second connecting plate 140 is rotated to a certain angle, and the top of the outer surface of the tower segment of the tower segment assembly 13 is lowered, so that it is convenient for the staff to process the top of the tower segment. In addition, when it is necessary to process the inner surface of the tower segment, the second connecting plate 140 can also be rotated to lift one side edge of the tower segment assembly 13, so that it is convenient for the staff to enter the inner side of the tower segment assembly 13 from the lifted side of the tower segment assembly 13, so as to facilitate the processing of the inner surface of the tower segment.

[0080] like Fig.16 , Fig.19 and Fig.23As shown, the sandblasting and rust removal tool also includes: a second telescopic device 150, the second telescopic device 150 has a fixed end and a telescopic end 151, the fixed end is pivotally connected to the base 110, and two pivot structures are provided on the second connecting plate 140, and the two pivot structures are pivotally connected to the telescopic end 151 and the base 110 respectively. Specifically, when the telescopic end 151 of the second telescopic device 150 is extended and retracted, the second connecting plate 140 can rotate along the pivot structure pivotally connected to the base 110. The above structure is simple and low in cost.

[0081] like Fig.16 , Fig.19 , Fig.21 and Fig. 22 As shown, the base 110 includes a base body 111 and a support frame 112 disposed on the base body 111 and extending upward, and the pivot structure is pivotally connected to the top of the support frame 112. The above structure is simple and low in cost.

[0082] like Fig.16 and Fig.23 As shown, the second telescopic device 150 includes a first electric cylinder. The above structure is simple, low in cost, and highly reliable.

[0083] like Fig.16 , Fig.19 and Fig.21 As shown, a limiting groove 133 is provided on the support surface 131. Specifically, the four corners of the tower segment assembly 13 are all limited in the limiting groove 133 to prevent the tower segment assembly 13 from moving during the lifting process. On the one hand, it ensures that the tower segment assembly 13 can be stably limited on the first telescopic device 130 to avoid falling; on the other hand, after the surface of the segment tower flange 121 that has not been subjected to the sandblasting and rust removal operation is sandblasted and rust-removed, it is also necessary to retract the first telescopic device 130 so that the second connecting plate 140 and the segment tower flange 121 are reconnected together for subsequent anti-corrosion operations. If the tower segment assembly 13 is displaced during the lifting process, it will increase the difficulty of reconnecting the second connecting plate 140 and the segment tower flange 121.

[0084] like Fig.16 , Figure 20 to Figure 23As shown, the second connecting plate 140 includes a mounting beam 141 extending along a preset direction y and a plate body 142. The plate body 142 includes a fitting surface that fits with the end surface of the segmented tower flange 121. The connecting structure is a plurality of connecting holes 143 arranged on the fitting surface and arranged along an arc track. The plate body 142 is adjustably arranged on the mounting beam 141 along a direction z perpendicular to the preset direction y. The above structure enables the segmented tower flange 121 to maintain a distance from the second connecting plate 140 when the tower segment assembly 13 is placed on the first telescopic device 130. On the one hand, it is convenient to lower the tower segment assembly 13; on the other hand, it prevents the second connecting plate 140 from being worn out, thereby ensuring the service life of the sandblasting and rust removal tooling.

[0085] like Fig.16 and Fig.17 As shown, the mounting beam 141 includes a beam body 144 and a mounting plate 145 disposed on the upper surface of the beam body 144, the plate body 142 includes a mounting vertical plate 146 and a mounting flat plate 147 connected to each other, the mounting flat plate 147 is provided with an adjustment hole 148 extending along the direction z, and the connecting member 160 passes through the adjustment hole 148 and the mounting plate 145 so that the mounting flat plate 147 is adjustably connected to the mounting plate 145. The above structure is simple, low in cost, and easy to operate.

[0086] Preferably, the limiting groove 133 extends in a direction z perpendicular to the preset direction y. The above structure enables the limiting groove 133 to limit the tower segment assembly 13 in the preset direction y, preventing the tower segment assembly 13 from moving in the preset direction y. When the connection hole 143 is aligned with the connection hole on the segment tower flange 121, it is not necessary to consider whether the two are aligned in the preset direction y, and it is sufficient to adjust the first telescopic device 130 to rise and fall.

[0087] like Fig.16 As shown, the first telescopic device 130 includes two second electric cylinders 132 arranged at intervals along a preset direction y, and the upper surfaces of the second electric cylinders 132 form support surfaces 131 for supporting the end corners of the tower segment assembly 13. The above structure is simple, low in cost, and highly reliable.

[0088] like Fig.16 As shown, the sandblasting and rust removal tool also includes: a moving device 170, which is arranged on the base 110 so that the sandblasting and rust removal tool can be movably arranged. The above structure enables the sandblasting and rust removal tool to move flexibly with the tower segment assembly 13 thereon, making the transportation of the tower segment assembly 13 time-saving and labor-saving.

[0089] It should be noted that after the sandblasting and rust removal operation is performed on the surface of the segmented tower flange 121 that has not been subjected to the sandblasting and rust removal operation, it is necessary to retract the first telescopic device 130 so that the second connecting plate 140 and the segmented tower flange 121 are realigned and then connected together. In order to shorten the time for the second connecting plate 140 to realign with the segmented tower flange 121, the sandblasting and rust removal tooling also includes a third telescopic device (not shown in the figure), which is arranged on the base 110 and extends upward. The working process of the sandblasting and rust removal tooling is described in detail below:

[0090] First, place the four corners of the tower segment assembly 13 on the support surface 131 of the first telescopic device 130, and then move the first telescopic device 130 until the second connecting plate 140 is opposite to the segment tower flange 121. Then, connect the second connecting plate 140 and the segment tower flange 121 together through the connecting structure. After the connection is completed, the tower segment assembly 13 can be sandblasted and derusted. After the sandblasting and derusting are completed, drive the third telescopic device to extend to the position against the inner surface of the tower segment assembly 13. Then, cancel the connection relationship between the second connecting plate 140 and the segment tower flange 121, drive the first telescopic device 130 to move, so that the segment tower flange 121 and the second connecting plate 140 are mutually displaced. At this time, the surface of the segment tower flange 121 that has not been sandblasted and derusted is sandblasted and derusted. After the sandblasting and derusting are completed, the end face of the segment tower flange 121 is sprayed with paint (anti-corrosion). Then, the first telescopic device 130 is driven to retract until the third telescopic device and the inner surface of the tower segment assembly 13 are again in contact with each other. Then, the second connecting plate 140 is connected to the segment tower flange 121, and the tower segments of the tower segment assembly 13 are subjected to the final anti-corrosion work by sandblasting and rust removal tooling. As mentioned above, the second telescopic device 150 can be used to rotate the second connecting plate 140 to achieve the purpose of uniform spraying of paint. Finally, the treated tower segment assembly 13 is sent to the yard by the moving device 170.
