Description

Technical Field

[0001] The invention relates to the field of slice tower processing, and in particular to a sandblasting and rust removal tool, a sandblasting and rust removal tool assembly and a slice tower processing device. 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 sandblasting and rust removal tool, a sandblasting and rust removal tool assembly and a processing device for a slice tower, so as to solve the problem in the prior art that the processing of the slice tower has extremely high requirements on the size of the factory building.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a sandblasting and rust removal tool for a tower segment assembly is provided, comprising: a base; a first telescopic device, which is arranged on the base, and the first telescopic device has a supporting surface for supporting the tower segment assembly; a connecting plate, which is arranged on the base, and a connecting structure connected to the segment tower flange of the tower segment assembly is provided on the connecting plate.

[0012] In one embodiment, the mounting beam includes a beam body and a mounting plate arranged on the upper surface of the beam body, the plate body includes a mounting vertical plate and a mounting flat plate connected to each other, the mounting flat plate is provided with an adjustment hole extending along the direction z, and the connecting member passes through the adjustment hole and the mounting plate so that the mounting flat plate can be adjusted in position and connected to the mounting plate.

[0013] In one embodiment, the first telescopic device includes two second electric cylinders arranged at intervals along a preset direction y, and the upper surfaces of the second electric cylinders form supporting surfaces for supporting the end corners of the tower segment assembly.

[0014] In one embodiment, the sandblasting and rust removal tool further includes: a moving device, which is arranged on the base so that the sandblasting and rust removal tool can be movably arranged.

[0015] In one embodiment, the sandblasting and rust removal tool further includes: a third telescopic device, which is arranged on the base and extends upward.

[0016] According to another aspect of the present invention, a sandblasting and rust removal tooling assembly of a tower segment assembly is provided, comprising: two sandblasting and rust removal tools arranged at intervals, the sandblasting and rust removal tools being the above-mentioned sandblasting and rust removal tools.

DETAILED DESCRIPTION

[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein.

[0049] 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.

[0050] In order to solve the problem raised by the background technology, the false flange is no longer connected to the tower. After the tower segmentation step, the tower is moved out of the black tower workshop as a whole and opened by opening the tooling to form a multi-piece tower segment assembly. Then, each tower segment assembly is sandblasted and derusted by the sandblasting and derusting tooling. Then, each tower segment assembly is subjected to corrosion protection, and finally the single-piece tower segment assembly is transported out of the white tower workshop and transported to the yard. Since the false flange is no longer connected during the entire process of processing the tower, most tower manufacturers can process segmented towers without rectifying the original factory buildings and some processing auxiliary equipment, which is conducive to the promotion and development of segmented tower technology.

[0051] It should be noted that if Figure 5 and Fig. 9As shown, the tower actually includes a tower body and two flanges arranged at both ends of the tower body, wherein the tower body is welded by a plurality of cylinder sections, and the flange 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 is divided into three tower segments. Each tower segment and the two segmented tower flanges 121 at its two ends form a set of tower segment components 13.

[0052] Specifically, Figure 1 and Figure 4 As shown, the sandblasting and rust removal tooling of the tower segment assembly 13 of this embodiment includes a base 110, a first telescopic device 130 and a 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 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 arranged on the connecting plate 140.

[0053] By applying the technical solution of this embodiment, when a 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 connecting plate 140 is opposite to the segment tower flange 121. Then, the connecting plate 140 and the segment tower flange 121 are connected together 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 connecting plate 140 and the segment tower flange 121 are connected together, the fitting surface of the segment tower flange 121 and the connecting plate 140 is not sandblasted and rust removed. In order to enable the entire tower segment assembly 13 to be fully sandblasted and derusted, in this embodiment, the connection relationship between the 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 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. On the one hand, 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; on the other hand, the tower can be sandblasted and derusted smoothly through the sandblasting and derusting tooling without a false flange, so that most tower manufacturers can process segment towers, which is conducive to the promotion and development of segment tower technology.

[0054] 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. Figure 4 and Figure 8 As shown, the 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 connecting plate 140 is first rotated to a certain angle, so that the tower segment assembly 13 connected to the 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 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.

[0055] like Figure 4 and Figure 8 As shown, in this embodiment, the sandblasting and rust removal tooling 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 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 connecting plate 140 can rotate along the pivot structure pivotally connected to the base 110. The above structure is simple and low in cost.

[0056] like Figure 1 , Figure 4 and Figure 8 As shown, in this embodiment, 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.

[0057] like Figure 1 As shown, in this embodiment, the second telescopic device 150 includes a first electric cylinder. The above structure is simple, low in cost, and highly reliable.

[0058] like Figure 1 and Figure 6As shown, in this embodiment, 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 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 connecting plate 140 and the segment tower flange 121.

[0059] like Figures 1 to 3 As shown, in this embodiment, the 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 along an arc track and arranged on the fitting surface, and 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 connecting plate 140 when the tower segment assembly 13 is placed on the first telescopic device 130, which, on the one hand, facilitates the lowering of the tower segment assembly 13; on the other hand, prevents the connecting plate 140 from being worn out, thereby ensuring the service life of the sandblasting and rust removal tooling.

[0060] like Figure 1 and Figure 2 As shown, in this embodiment, 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.

[0061] Preferably, in this embodiment, 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 or fall.

[0062] like Figure 1As shown, in this embodiment, the first telescopic device 130 includes two second electric cylinders 132 arranged at intervals along the preset direction y, and the upper surface of the second electric cylinder 132 forms a supporting surface 131 for supporting the end angle of the tower segment assembly 13. The above structure is simple, low in cost, and highly reliable.

[0063] like Figure 1 As shown, in this embodiment, the sandblasting and rust removal tooling also includes: a moving device 170, which is arranged on the base 110 so that the sandblasting and rust removal tooling can be movably arranged. The above structure enables the sandblasting and rust removal tooling to be flexibly moved with the tower segment assembly 13 thereon, making the transportation of the tower segment assembly 13 time-saving and labor-saving.

[0064] 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 connecting plate 140 and the segmented tower flange 121 are realigned and then connected together. In order to shorten the time for the connecting plate 140 to realign with the segmented tower flange 121, in this embodiment, 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:

[0065] 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 connecting plate 140 is opposite to the segment tower flange 121. Then, connect the 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 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 connecting plate 140 are displaced from each other. 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 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 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.

[0066] The present application also provides a sandblasting and rust removal tooling assembly, such as Figures 5 to 8As shown, according to an embodiment of the sandblasting and rust removal tooling assembly of the present application, it includes two sandblasting and rust removal tools 180 arranged at intervals, and the sandblasting and rust removal tooling 180 is the above-mentioned sandblasting and rust removal tooling. Specifically, the two flanges of the tower segment assembly 13 are respectively connected to the connecting plates 140 of the two sandblasting and rust removal tools 180. Since the above-mentioned sandblasting and rust removal tooling has the advantages of making the sandblasting and rust removal and anti-corrosion effects of the tower segment assembly good, the sandblasting and rust removal tooling assembly having it also has the above-mentioned advantages. In addition, the sandblasting and rust removal tooling assembly includes two separate sandblasting and rust removal tools 180, which can be adapted to tower segment assemblies 13 of different lengths, thereby making the sandblasting and rust removal tooling assembly highly versatile.

[0067] Of course, in other embodiments, the sandblasting and rust removal tool may include two oppositely disposed connecting plates, and the two oppositely disposed connecting plates are disposed together on the same base.

[0068] The present application also provides a processing device for a slicing tower. The processing device for a slicing tower according to an embodiment of the present application includes: an opening tool 90 and a sandblasting and rust removal tool assembly 100. Figures 9 to 23 As shown, the tower of the segmented tower is opened by opening the tool 90 to form a plurality of tower segmented assemblies 13. The sandblasting and rust removal tool assembly 100 is the above-mentioned sandblasting and rust removal tool assembly. Since the above-mentioned sandblasting and rust removal tool assembly has the advantages of sandblasting and rust removal, good anti-corrosion effect and strong versatility, the processing device having it also has the above-mentioned advantages. In addition, by using the above-mentioned processing device to process the segmented tower, it is possible to no longer set a false flange, so that most tower production plants can process the segmented tower, which is conducive to the promotion and development of the segmented tower technology.

[0069] like Fig. 9 , Fig.10 , Fig.13 , Fig.14 , Figures 19 to 23 As shown, the tower opening tooling of this embodiment 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 connecting plates 52 arranged on the first bracket body 51, and each connecting plate 52 is connected to a different segmented tower flange 121.

[0070] Applying the technical solution of this embodiment, when it is necessary to open the tower, first place the tower 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 connecting plate bodies 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 connecting plate bodies 52 of the fixed bracket 50 on the corresponding side. Then, cancel the connection relationship between the longitudinal flange 12 of the upper tower segment assembly and the other longitudinal flanges 12, and hoist the upper tower segment assembly to the sandblasting and rust removal tooling assembly by a crane. Next, cancel the connection relationship between the longitudinal flange 12 of the right tower segment assembly and the longitudinal flange 12 of the left tower segment assembly, and remove the segment tower flange 121 of the right tower segment assembly from the connecting plate body 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 connecting plate body 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 connecting plate body 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.

[0071] It should be noted that, in the present embodiment, the upper segmented tower flange located on the upper side of the multi-slice tower flange 121 is not connected to any connecting plate body 52. ​​When the left tower segmented assembly is hoisted away, since the left and right segmented tower flanges are both connected to the connecting plate body 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 can be hoisted. 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.

[0072] It should also be noted that in other embodiments not shown in the figures, the number of connecting plates may be the same as the number of tower segment assemblies. What is different from this embodiment is that before the upper tower segment assembly is lifted off, the connection between the segment tower flange 121 of the upper tower segment assembly and the upper connecting plate 52 needs to be cancelled. When the number of connecting plates is the same as the number of tower segment assemblies, the order of lifting off the tower segment assemblies may also be different from the above order.

[0073] like Fig. 9 , Figures 14 to 17 As shown, in this embodiment, a plurality of connecting plates 52 are arranged at intervals along a direction x perpendicular to the preset direction w, and the connecting plates 52 are slidably disposed on the first bracket body 51, and the connecting plates 52 are connected to the first bracket body 51 through the first fasteners 60. Specifically, after the tower segment flange 121 of the tower segment assembly is removed from the corresponding connecting plate 52, the 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.

[0074] like Figures 14 to 17 As shown, in this embodiment, the first bracket body 51 is provided with a first slide groove 511 extending along the direction x, the connecting plate body 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.

[0075] like Fig.10 As shown, in this embodiment, a first handle 53 is provided on the connecting plate body 52. ​​The above structure facilitates the staff to move the connecting plate body 52 and improves the user experience.

[0076] like Fig. 9 and Fig.18 As shown, in this embodiment, 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.

[0077] like Fig. 9 and Fig.12 As shown, in this embodiment, 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.

[0078] like Fig. 9 and Fig.12As shown, in this embodiment, 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 and improves the user experience.

[0079] like Fig. 9 and Fig.18 As shown, in this embodiment, 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.
