Description

Technical Field

[0001] This invention belongs to the field of wind power new energy construction technology, and more specifically, relates to a storage device and method applicable to multiple types of mixed tower sections. Background Technology

[0002] As the wind power market moves towards larger scales, wind turbine towers are increasingly adopting reinforced concrete structures. As the core component of the concrete tower, the composite tower sections need to be transported in batches to the construction site and stored upright; they cannot be laid horizontally or stacked. The quality of this storage directly affects the tower assembly accuracy, structural safety, and construction costs. Traditional on-site storage methods place the composite tower sections directly on the wind turbine platform, making the bottom of the sections susceptible to contamination and damage. This necessitates additional cleaning and reinforcement, and in cases of severe damage, flaw detection and return to the factory are required, significantly reducing assembly and installation efficiency and increasing construction costs.

[0003] Patent CN202323947887 discloses a wind turbine mixed tower segment stacking rack, which adopts an H-beam steel support, steel bar positioning, detachable guardrail and wooden wedge fixing structure, which can realize the vertical stacking of tower segments, prevent tipping and ground contact and contamination, and play a certain role in protecting the finished tower segments. However, the stacking rack is a fixed size structure, which cannot be adapted to mixed tower segments of different diameters and widths, and has poor versatility. When changing different models of tower segments on site, the support needs to be remade or adjusted, which is time-consuming and labor-intensive. At the same time, its support and positioning methods are simple, lacking adjustable support and modular quick disassembly and assembly design, resulting in low relocation and reuse efficiency, and making it difficult to meet the needs of batch storage and rapid turnover of multi-specification tower segments on construction sites.

[0004] Therefore, there is an urgent need at present for a simple, adaptable, safe and reliable mixed tower plate storage device and usage method to improve the construction quality and safety of mixed towers and achieve cost reduction and efficiency improvement. Summary of the Invention

[0005] To address the shortcomings of existing mixed-tower tray storage technologies, such as insufficient versatility, inconvenient adjustment, poor reusability, and weak on-site adaptability, this invention provides a storage device and method applicable to various types of mixed-tower trays to solve these problems.

[0006] To achieve the above objectives, the present invention provides a storage device suitable for various types of mixed tower trays, comprising a horizontally mounted telescopic support frame, which includes multiple sets of parallel telescopic crossbeams and telescopic longitudinal beams connecting the multiple sets of telescopic crossbeams; each telescopic crossbeam includes a horizontal sleeve, with horizontal sliding tubes slidably mounted at both ends of the horizontal sleeve cavity, and an end sleeve fixedly mounted at the outer end of the horizontal sliding tube, the horizontal sliding tube extending and retracting linearly along the horizontal sleeve to adapt to the diameter of the tower tray; each telescopic longitudinal beam includes multiple sets of longitudinal tubes with progressively increasing diameters, one end of which is vertically and fixedly connected to the middle of the telescopic crossbeam, and the other end passes through an adjacent telescopic crossbeam and is slidably nested within the larger diameter longitudinal tube, achieving longitudinal scaling. The tower plate features stepless inch adjustment; support platforms fixed at the top middle of the horizontal sleeve and the top of the end sleeve, which lift the middle and both ends of the tower plate and isolate the bottom of the tower plate from the ground; a positioning bracket located above the end sleeve, fixed on the top of the corresponding support platform, which horizontally limits the ends of the tower plate; and an anti-tipping mechanism, which includes a telescopic rod and a claw. One end of the telescopic rod is connected to the middle of the telescopic crossbeam. The telescopic rod raises the claw to the top middle of the tower plate by telescopic movement, and the angle of the claw is adjusted to engage the top of the tower plate, forming a flexible clamp and top limit. Together with the telescopic support frame and the tower plate, it forms a triangular support system to prevent the tower plate from tipping over during storage.

[0007] Furthermore, the anti-tipping mechanism also includes a lower connecting seat, which is fixedly mounted on the rear side of the support platform. It forms a rear rigid limit on the tower plate by the bottom middle section of the arc surface of the tower plate, and forms a front-to-back bidirectional constraint with the positioning card seat for the front limit on the end of the tower plate. The lower connecting seat has a lower pin hole through both sides for inserting a connecting pin shaft to achieve a hinge connection with the bottom end of the telescopic rod.

[0008] Furthermore, the bottom end of the telescopic rod is hinged to the lower connecting seat via a connecting pin, and the top end is hinged to the pawl. It includes a support tube and an adjusting tube. The support tube is made of high-strength seamless steel pipe, with a hinge hole at the bottom end, and is hinged to the lower pin hole of the lower connecting seat via a pin. The side wall of the support tube is evenly provided with multiple sets of equally spaced positioning holes along the axial direction for locking and fixing after length adjustment. The adjusting tube is slidably nested in the cavity of the support tube, and its side wall is evenly provided with multiple sets of adjusting holes along the axial direction. The diameter and spacing of the adjusting holes are perfectly matched with the positioning holes. After adjustment to the target length, the positioning pin is inserted into the aligned positioning hole and adjusting hole to complete the length locking of the telescopic rod.

[0009] Furthermore, the claw is located at the top of the regulating tube and has an inverted U-shaped structure. Its front end has an upper pin hole and is hinged to the top of the regulating tube through a connecting pin. The inverted U-shaped groove of the claw completely engages with the top surface and the inner and outer arc surfaces of the tower plate to form a stable surface contact clamping.

[0010] Furthermore, the transverse sleeve is a hollow tubular structure, and the cavity inside provides sliding guidance and force support for the transverse sliding tube; there are two sets of transverse sliding tubes, which are slidably embedded at both ends of the transverse sleeve cavity, and the transverse beam can be infinitely adjusted in the lateral dimension by synchronous linear telescopic displacement along the axial direction of the transverse sleeve; the end sleeve is fixedly set at the outer end of a single transverse sliding tube, and its inner and outer diameters are the same as those of the transverse sleeve, so that the transverse beam remains horizontal.

[0011] Furthermore, the telescopic longitudinal beam includes multiple sets of longitudinal tubes with progressively increasing diameters. One end of a single longitudinal tube is vertically and fixedly connected to the middle position of the transverse sleeve of the corresponding telescopic crossbeam, and the other end passes through the adjacent telescopic crossbeam and is slidably embedded in the cavity of the adjacent longitudinal tube with a larger diameter.

[0012] Furthermore, the main body of the support platform is made of high-strength steel, and the top supporting surfaces of multiple support platforms are all on the same horizontal plane. A first buffer pad is provided on the top of the support platform, which is made of flexible materials such as rubber or geotextile.

[0013] Furthermore, the positioning bracket is fixedly mounted on the support platform at the top of the end sleeve. It has a U-shaped structure with the U-shaped opening facing the end of the tower plate, thereby limiting the left, right and front sides of the end of the tower plate.

[0014] Furthermore, the top and U-shaped opening of the positioning card seat are chamfered, and a second buffer pad is provided on the inner side. The second buffer pad is made of flexible materials such as rubber or geotextile.

[0015] According to another aspect of the present invention, a method for storing multi-type mixed tower trays is also provided, comprising the following steps: S1: Horizontally lay the telescopic load-bearing frame to the preset position on the wind turbine platform according to the tower plate specifications, and build a modular load-bearing base; S2: Adjust the telescopic beam to achieve stepless lateral expansion and contraction, adapt to tower plates of different diameters, and synchronously drive the support platform to align. S3: The sliding telescopic longitudinal beam enables stepless longitudinal adjustment, adapting to tower sections of different widths and ensuring precise support spacing; S4: Hoist the tower sections so that their ends are embedded in the positioning brackets to complete the bottom horizontal limit and ground isolation protection; S5: Raise the telescopic rod upward around the lower connecting seat and adjust the length to match the height of the tower plate; S6: Adjust the angle of the claws to engage the top of the tower plate, forming a flexible clamp and top limit; S7: Locking telescopic rod, together with the tower plate and telescopic load-bearing frame, forms a stable triangular support, completing safe storage in all dimensions.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The storage device of the present invention achieves universal compatibility with all specifications through a bidirectional stepless telescopic design, completely breaking the application limitations of traditional fixed-size stacking racks; the telescopic bearing frame of the device can adapt to mixed tower plates of different diameters through the synchronous telescopic expansion and contraction of the telescopic crossbeams, and adapt to tower plates of different widths through the nested sliding of the telescopic longitudinal beams. Components such as the support platform and positioning card can move synchronously with the telescopic structure. The adjustment process does not require secondary disassembly and assembly or drilling for positioning on site, nor does it require custom-made special brackets for different models of tower plates. One set of devices can cover the storage needs of the entire series of mixed tower plates in the project, greatly improving the flexibility and adaptability of on-site operations.

[0017] 2. The storage device of this invention achieves full-cycle protection of the finished tower sections, improving the construction quality of the mixed tower from the source. It completely isolates the bottom of the tower sections from the ground through a three-point support platform, avoiding ground contamination and impact damage. At the same time, flexible buffer pads are set on the contact surfaces of the support platform, positioning card seat, and claws with the tower sections, completely eliminating the rigid direct contact between metal components and concrete tower sections. This effectively avoids damage such as chipping and scratches on the tower sections, significantly reducing the additional processes of subsequent tower section cleaning, reinforcement, flaw detection, and even return to the factory. It ensures the shape and position accuracy of the tower sections and lays a solid foundation for the subsequent high-precision assembly of the tower.

[0018] 3. The storage device of the present invention forms a horizontal bidirectional limit at both ends of the tower section through the U-shaped positioning bracket, resisting the risk of lateral slippage and tilting of the tower section; a stable triangular support system is formed by the anti-tipping mechanism and the bottom support point, locking the degree of freedom of the top of the tower section to overturn; at the same time, the front limit of the positioning bracket and the rear limit of the lower connecting seat form a front-to-back bidirectional closed-loop constraint along the axial direction of the tower, which can effectively resist various external forces such as on-site wind load, hoisting aftershocks, and personnel contact, completely eliminating safety accidents such as tower section slippage, movement, and tilting. The structure has high load-bearing rigidity and stable stress, and has sufficient safety redundancy for long-term storage, fully meeting the safety production requirements of wind power construction sites.

[0019] 4. The storage device of this invention adopts an integrated prefabricated modular structure, with no complex and easily damaged parts. It requires no welding or secondary processing on site, and can quickly complete the assembly, size adjustment and array arrangement of the device. The installation and adjustment of the anti-tipping mechanism can be completed by a single person without the assistance of large equipment. The telescopic load-bearing frame can be folded and retracted, making it convenient for relocation and transportation. It can be reused across projects without the need to customize special storage equipment for different projects, which greatly reduces equipment investment costs and on-site installation and dismantling time, effectively shortens the construction preparation cycle, and perfectly adapts to the construction needs of wind power projects with multiple work sites and fast turnover.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1-7As shown, this invention provides a storage device suitable for various types of mixed tower plates, including a telescopic support frame 1, a support platform 2, a positioning bracket 3, and an anti-tipping mechanism 4. The telescopic support frame 1 is horizontally positioned on the ground and includes multiple sets of parallel telescopic crossbeams 11 and a telescopic longitudinal beam 12 connecting the multiple sets of telescopic crossbeams 11. Each telescopic crossbeam 11 includes a horizontal sleeve 111, with two sets of horizontal sliding tubes 112 slidably disposed at both ends within its cavity. An end sleeve 113 is fixedly disposed at the outer end of each horizontal sliding tube 112. By synchronously pushing the two sets of horizontal sliding tubes 112 to perform linear telescopic displacement along the horizontal sleeve 111, the telescopic crossbeam 11 adapts to the diameter of the tower plate 5. The telescopic longitudinal beam 12 includes multiple sets of longitudinal beams with progressively increasing diameters. One end of each longitudinal beam is vertically fixed to the middle of the telescopic crossbeam 11, and the other end passes through an adjacent telescopic crossbeam 11 and slidably is disposed on the side with the larger diameter. Within the longitudinal tube, the longitudinal dimension is infinitely adjustable through the sequential nesting and sliding of multiple sets of corresponding longitudinal tubes. The support platform 2 is fixedly installed at the top middle of the horizontal sleeve 111 and the top of the end sleeve 113, respectively, to support the middle section and both ends of the arc-shaped tower plate 5, isolating its bottom from the ground. The positioning bracket 3 is fixedly installed on the top of the support platform 2, located directly above the end sleeve 113, and horizontally limits the ends of the tower plate 5. The anti-tipping mechanism 4 includes a telescopic rod 41 and a claw 42. One end of the telescopic rod 41 is located at the middle of the telescopic beam 11, and the other end lifts the claw 42 to the top middle of the tower plate 5 through telescopic movement for clamping and limiting, thereby forming a triangular support system to prevent the tower plate 5 from tipping over during storage. The storage device of this invention is suitable for storing mixed tower plates of different sizes, solving the problems of poor versatility of traditional fixed-size platforms, time-consuming and laborious replacement and adjustment, and the need for additional customized platforms to adapt to tower plates of different sizes, thus achieving the effect of improving construction efficiency and reducing equipment investment costs.

[0024] like Figure 1-4 As shown in the embodiment of the present invention, the telescopic bearing frame 1 provides a stable bearing base for storing different types of tower plates 5, and includes a telescopic crossbeam 11 and a telescopic longitudinal beam 12.

[0025] The telescopic crossbeam 11 is arranged in multiple sets horizontally and parallel to accommodate arc-shaped mixed tower plates 5 of different diameters, adjusts the lateral support span of the device, and matches the support point requirements of the middle and both ends of the tower plate 5. It includes a horizontal sleeve 111, a horizontal sliding tube 112, and an end sleeve 113. The horizontal sleeve 111 is a hollow tubular structure, and through its internal cavity, it provides sliding guidance and force support for the horizontal sliding tube 112. Furthermore, a support platform 2 is fixedly installed at the middle position of the top of the horizontal sleeve 111 to support the middle section of the arc-shaped tower plate 5, achieving complete isolation between the bottom of the tower plate 5 and the ground, and preventing the tower plate from being contaminated or damaged by impact. Furthermore, the middle part of the tube body of the horizontal sleeve 111 is vertically and fixedly connected to the telescopic longitudinal beam 12, thereby achieving a fixed connection between the telescopic crossbeam 11 and the telescopic longitudinal beam 12, forming a stable ground support structure for the device. Two sets of transverse sliding tubes 112 are provided, respectively slidably embedded at both ends of the cavity of the transverse sleeve 111. By synchronously extending and retracting along the axial direction of the transverse sleeve 111, the transverse beam 11 can be infinitely adjusted in lateral dimension. By synchronously pushing the two sets of transverse sliding tubes 112 to extend or retract along the transverse sleeve 111, the overall lateral span of the transverse beam 11 can be flexibly adjusted, precisely matching tower plates 5 of different diameters. This eliminates the need to remake supports for different tower plate models, greatly improving the versatility of the device and on-site construction efficiency. The end sleeve 113 is fixedly installed at the outer end of the single horizontal sliding tube 112, and its inner and outer diameters are the same as those of the horizontal sleeve 111, so that the telescopic beam 11 remains horizontal. A support platform 2 is fixedly installed on the top of the end sleeve 113 to support the two ends of the arc-shaped tower plate 5, forming a three-point stable support system with the support platform 2 on the top of the horizontal sleeve 111. At the same time, a positioning bracket 3 is fixedly installed on the support platform 2 on the top of the end sleeve 113, facing the end of the tower plate 5, which can horizontally limit the two ends of the tower plate 5, prevent horizontal slippage of the tower plate during storage, and improve storage stability.

[0026] The telescopic longitudinal beam 12 connects multiple sets of parallel telescopic crossbeams 11 into one unit, while simultaneously enabling stepless adjustment of the longitudinal dimensions of the device, adapting to tower plates 5 of different widths, and ensuring precise matching between the longitudinal spacing of multiple support platforms 2 and the width of the tower plates 5. The telescopic longitudinal beam 12 includes multiple sets of longitudinal pipes with progressively increasing diameters. One end of a single longitudinal pipe is vertically and fixedly connected to the middle position of the transverse sleeve 111 of the corresponding telescopic crossbeam 11, and the other end passes through the adjacent telescopic crossbeam 11 and is slidably embedded in the cavity of the adjacent longitudinal pipe with a larger diameter. In one embodiment of the present invention, the telescopic longitudinal beam 12 includes a first longitudinal pipe 121, a second longitudinal pipe 122, and a third longitudinal pipe 123. The two ends of the first longitudinal pipe 121 are vertically and fixedly connected to the middle ends of two adjacent sets of telescopic crossbeams 11, respectively. The second longitudinal pipe 122 and the third longitudinal pipe 123 are nested sequentially and are vertically and fixedly connected to the middle ends of two other telescopic crossbeams 11, respectively. By sequentially nesting and sliding multiple sets of corresponding longitudinal tubes, the longitudinal dimension of the telescopic load-bearing frame 1 can be infinitely adjusted to accommodate tower plates 5 of different widths. Simultaneously, it ensures that the multiple sets of telescopic beams 11 remain parallel during adjustment, guaranteeing uniform stress and structural stability of the entire device. This nested telescopic design, combined with the lateral adjustment of the telescopic beams 11, achieves bidirectional flexible adaptation on the horizontal plane of the device. Furthermore, the modular splicing design allows for rapid disassembly, assembly, and reuse, meeting the needs for bulk storage and rapid turnover of tower plates 5 of various specifications on the construction site.

[0027] The support platform 2 is used to separate the tower section 5 from the ground and directly bears all the vertical load of the tower section 5. The support platform 2 has three sets on the telescopic beam 11. The first set is fixed at the top middle of the horizontal sleeve 111 of the telescopic beam 11, corresponding to the middle section of the arc bottom of the arc-shaped tower section 5, providing central support for the tower section. The second set is fixed at the top of the end sleeves 113 at both ends of the telescopic beam 11, corresponding to the two end support points of the arc-shaped tower section 5, providing symmetrical and stable support for both ends of the tower section. The support platform 2 and the telescopic beam 11 are prefabricated and integrated, allowing for synchronous adjustment of the distance between the two end support platforms 2 and the middle support platform 2 as the horizontal sliding tube 112 expands and contracts along the horizontal sleeve 111, precisely matching the support points of tower sections 5 with different diameters. Simultaneously, with the longitudinal expansion and contraction of the telescopic beam 12, the longitudinal spacing of multiple sets of support platforms 2 is adjusted synchronously to adapt to tower sections 5 of different widths, eliminating the need for secondary disassembly and repositioning on-site, significantly improving construction efficiency.

[0028] Furthermore, the main body of the support platform 2 is made of high-strength steel, possessing excellent vertical bearing capacity, bending resistance, and deformation resistance. It can withstand the long-term static load of heavy mixed tower plates, preventing settlement and deformation during storage, ensuring the positional accuracy of the tower plates, and eliminating problems such as tower plate cracking and assembly deviation caused by support deformation. The bottom of the support platform 2 is rigidly connected to the telescopic bearing frame 1 by welding or high-strength bolts, ensuring that the vertical load can be evenly and stably transferred to the ground, avoiding local stress concentration. The top supporting surfaces of multiple sets of support platforms 2 are all on the same horizontal plane. With the overall leveling of the telescopic bearing frame 1, the vertical load of the tower plates 5 can be evenly distributed at each support point, avoiding local overload of the tower plates due to differences in the height of the support surfaces. At the same time, it ensures the verticality of the tower plates during upright storage, providing a basic condition for the stable limiting of the anti-tipping mechanism 4. Preferably, the top of the support platform 2 is provided with a first buffer pad layer, which is made of flexible materials such as rubber or geotextile. This not only avoids the damage caused by direct contact between the concrete surface of the tower plate and the rigid component, such as bumps, scratches, and chipping, but also increases the friction of the contact surface, preventing the tower plate 5 from slipping during storage. This reduces the additional procedures of subsequent tower plate cleaning, reinforcement, flaw detection, or even return to the factory for treatment from the source, thereby reducing construction costs.

[0029] In this embodiment of the invention, the positioning bracket 3 is used to precisely limit the horizontal position and lateral constraint of both ends of the arc-shaped mixed tower plate 5. It has a U-shaped structure and is fixedly installed on the support platform 2 at the top of the end sleeve 113. One set is set at each end of each telescopic beam 11. The U-shaped opening of the positioning bracket 3 faces the end of the tower plate 5, thereby limiting the left, right and front sides of the end of the tower plate 5. The opening width of the positioning bracket 3 is 2-5mm larger than the designed wall thickness of the tower plate 5, which ensures that the tower plate 5 can be smoothly embedded into the slot cavity when it is hoisted and placed, realizing rapid guidance and alignment, and avoids rigid hard contact damage to the concrete end of the tower plate 5 through a small gap. Preferably, the top of the positioning bracket 3 and the U-shaped opening are chamfered to avoid sharp edges scratching the surface of the tower plate 5 when it is hoisted and placed, and at the same time further improves the guidance and alignment efficiency. Furthermore, the inner side of the positioning bracket 3 is provided with a second buffer layer, which is made of flexible materials such as rubber or geotextile, to completely isolate the concrete end of the tower plate 5 from direct rigid contact with the metal bracket.

[0030] The positioning bracket 3 is integrally fixed to the support platform 2 at the top of the end sleeve 113. It can move synchronously with the axial expansion and contraction of the transverse sliding tube 112 along the transverse sleeve 111, automatically adapting to the end support points of tower pieces 5 of different diameters. No secondary disassembly and drilling for positioning is required on site, matching the stepless adjustment capability of the telescopic bearing frame 1. After the tower piece 5 is lifted and its position is adjusted, its two ends are aligned with the corresponding positioning bracket 3. Under the guidance of the chamfer on the positioning bracket 3, it is smoothly embedded into the U-shaped groove cavity. When the tower piece 5 is subjected to external forces such as on-site wind load, hoisting aftershock, or personnel contact, it will move outward. When the tower plate 5 tends to slip or tilt, the inner side of the positioning bracket 3 fits against the outer arc surface of the end of the tower plate 5, providing a reverse constraint limiting force to restrict its outward displacement. When the tower plate 5 is subjected to external load and tends to move forward along the tower axis, the positioning bracket 3 forms a rigid limit on the front side of the end of the tower plate 5, and at the same time, the lower connecting seat 43 of the anti-tipping mechanism 4 forms a reverse limit on the rear side of the middle section of the tower plate 5. The two work together to form a two-way constraint system along the tower axis, effectively preventing the tower plate 5 from axially shifting and overturning, and greatly improving the stability and safety of the tower plate 5 during storage.

[0031] like Figure 5-6 As shown, the anti-tipping mechanism 4 forms a rigid clamping limit on the middle section of the top of the tower piece 5, which, together with the bottom support point, constitutes a stable triangular support system to prevent the tower piece 5 from tipping over due to external forces, thereby preventing safety and quality accidents. The anti-tipping mechanism 4 includes a lower connecting seat 43, a telescopic rod 41, and a claw 42.

[0032] The lower connecting seat 43 is fixedly mounted on the rear side of the support platform, directly facing the bottom middle section of the rear arc surface of the tower plate 5. It can directly form a rear rigid limit on the tower plate 5, and together with the positioning card seat 3, it forms a front-to-back bidirectional constraint on the front limit of the end of the tower plate 5, preventing the tower plate 5 from moving along the axial direction of the tower. Furthermore, the connecting seat 43 has a lower pin hole 431 through on both sides for inserting a connecting pin shaft to achieve a hinge connection with the bottom end of the telescopic rod 41, providing a rotation fulcrum for the telescopic rod 41. It can adapt to different angles of lifting adjustment, thereby adapting to tower plates 5 with different arc curvatures.

[0033] The bottom end of the telescopic rod 41 is hinged to the lower connecting seat 43 via a connecting pin, and the top end is hinged to the claw 42, which can realize stepless length adjustment and adaptive angle adjustment. It includes a support tube 411 and an adjustment tube 412.

[0034] The support tube 411 is made of high-strength seamless steel pipe, with a hinge hole at the bottom end. It is hinged to the lower pin hole 431 of the lower connecting seat 43 through a pin shaft, providing the bottom rotation fulcrum and force support for the entire telescopic rod. Furthermore, the side wall of the support tube 411 is evenly provided with multiple sets of equally spaced positioning holes 413 along the axial direction for locking and fixing after length adjustment.

[0035] The regulating tube 412 is slidably nested in the cavity of the support tube 411, and can make linear telescopic displacement along the axial direction of the support tube 411 to achieve stepless adjustment of the overall length of the telescopic rod 41, and accurately adapt to the tower plates 5 of different heights; multiple sets of regulating holes 414 are evenly distributed along the axial direction on the side wall of the tube body. The hole diameter and hole spacing of the regulating holes 414 are completely matched with the positioning holes 413. After adjusting to the target length, the length of the telescopic rod 41 can be locked by inserting the positioning pin through the aligned positioning holes 413 and regulating holes 414, ensuring the support rigidity and preventing the rod from shrinking back under force.

[0036] The claw 42 is located at the top of the adjusting tube 412 and has an inverted U-shaped structure. Its front end has an upper pin hole 421. Hinged to the top of the adjusting tube 412 via a connecting pin, the angle of the claw 42 can be adaptively adjusted to maintain a horizontal position. The inverted U-shaped cavity of the claw 42 completely engages with the top surface and inner and outer arc surfaces of the tower plate 5, forming a stable surface contact clamping mechanism, avoiding stress concentration and tower plate damage caused by point contact. Furthermore, a third buffer layer is provided on the inner side of the claw 42. This third buffer layer is made of flexible materials such as rubber or geotextile, isolating the middle of the concrete top of the tower plate 5 from direct rigid contact with the claw 42.

[0037] In this embodiment of the invention, when the anti-tipping mechanism 4 is in operation, after the tower piece 5 is lifted and its position adjusted by the lifting equipment, its two ends are smoothly embedded into the U-shaped cavity under the guidance of the chamfered groove of the positioning seat 3, completing the bottom positioning and horizontal pre-limiting; the operator then pushes the telescopic rod 41 to rotate upward around the hinge point of the lower connecting seat 43, and moves the top claw 42 smoothly to the middle position of the top of the tower piece 5 along the inner arc surface of the tower piece 5; the hinge angle of the claw 42 is adjusted so that its inverted U-shaped cavity is completely engaged and fits against the top surface and inner and outer arc surfaces of the tower piece 5, completing precise clamping and positioning; then the length of the telescopic rod 41 is finely adjusted so that it is in a tensioned state, and the positioning pin is inserted into the aligned positioning hole 413 and adjustment hole 414 to lock the length of the telescopic rod 41. At this time, the telescopic rod 41, the tower piece 5, and the telescopic crossbeam 11 together form a stable triangular support system, completely restricting the tilting and rotational freedom of the tower piece 5.

[0038] By incorporating an anti-tipping mechanism 4, when the tower section 5 is subjected to external forces such as on-site wind load, hoisting aftershocks, or personnel contact, causing it to slip or tilt outwards from the center of the tower, the outer limiting plate of the positioning seat 3 provides a reverse constraint, limiting its outward displacement. When it tends to tilt inwards, the rigid support of the telescopic rod 41 and the clamping limit of the claw 42 provide a reverse support force, completely limiting its inward tilt. When the tower section 5 is subjected to external loads and tends to move forward along the tower axis, the positioning seat 3 forms a rigid limit on the front side of the end of the tower section 5, while the front limiting face of the lower connecting seat 43 forms a reverse limit on the rear side of the middle section of the tower section 5. The two work together to form a two-way closed-loop constraint along the tower axis, effectively preventing the tower section 5 from axially shifting and overturning.

[0039] When storing mixed tower plates, the storage device of this invention first arranges multiple sets of storage devices horizontally at preset points on the fan platform according to the specifications and array arrangement requirements of the mixed tower plates to be stored. Based on the diameter of the tower plate 5, the two sets of horizontal sliding tubes 112 of the telescopic beam 11 are simultaneously pushed to extend and retract axially along the horizontal sleeve 111, adjusting the transverse support span of the device. Based on the width of the tower plate 5, the longitudinal dimensions of the device are adjusted by the nesting and sliding of multiple sets of longitudinal tubes with progressively increasing diameters of the telescopic beam 12, completing the bidirectional stepless adjustment of the telescopic support frame 1, so that the support platform 2 at the top of the horizontal sleeve 111 and the end sleeve 113 precisely corresponds to the bottom support point of the tower plate 5. Then, the tower plate 5 is lifted by a lifting device and its lowering posture is adjusted so that the two ends of the tower plate 5 are aligned with the positioning brackets 3 at the top of the corresponding end support platforms 2. Guided by the chamfered groove of the positioning bracket 3, it smoothly embeds into its U-shaped groove cavity. Simultaneously, the bottom middle section of the arc surface of the tower plate 5 connects with the lower connecting seat 43. The system touches the limit position, thereby completing the vertical lifting and horizontal pre-limiting of the bottom of the tower plate 5. The three-point lifting system formed by multiple sets of support platforms 2 completely isolates the bottom of the tower plate 5 from the ground, achieving finished product protection. The operator pushes the telescopic rod 41 of the anti-tipping mechanism 4 upward around the hinge point of the lower connecting seat 43, moves the claw 42 at the top of the telescopic rod 41 to the middle position of the top of the tower plate 5, adjusts the hinge angle of the claw 42 so that its contour surface completely fits and clamps the top surface of the tower plate 5, and finely adjusts the length of the telescopic rod 41 to the tensioned state. Then, the length of the telescopic rod 41 is locked by inserting the positioning pin through the aligned positioning hole 413 and adjustment hole 414, so that the telescopic rod 41, the tower plate 5 and the telescopic bearing frame 1 form a stable triangular support system. At the same time, the positioning card seat 3 limits the front side of the end of the tower plate 5 and the lower connecting seat 43 limits the rear side of the middle section of the tower plate 5, forming a two-way closed-loop constraint along the tower cylinder axis, and finally completes the full-dimensional safe storage operation of the mixed tower plates.

[0040] The storage device of this invention achieves universal compatibility across all specifications through a bidirectional stepless telescopic design, completely breaking the application limitations of traditional fixed-size stacking racks. The telescopic load-bearing frame of this device can adapt to mixed tower plates of different diameters through the synchronous telescopic expansion and contraction of the telescopic crossbeams, and adapt to tower plates of different widths through the nested sliding of the telescopic longitudinal beams. Components such as the support platform and positioning card can move synchronously with the telescopic structure. The adjustment process does not require secondary disassembly and assembly or drilling for positioning on site, nor does it require custom-made special brackets for different models of tower plates. One set of devices can cover the storage needs of the entire series of mixed tower plates in a project, greatly improving the flexibility and adaptability of on-site operations.

[0041] The storage device of this invention achieves full-cycle protection of the finished tower sections, improving the construction quality of the mixed tower from the source. It completely isolates the bottom of the tower sections from the ground through a three-point support platform, avoiding ground contamination and impact damage. At the same time, flexible buffer pads are set on the contact surfaces of the support platform, positioning card seat, and claws with the tower sections, completely eliminating the rigid direct contact between metal components and concrete tower sections. This effectively avoids damage such as chipping and scratches on the tower sections, significantly reducing the additional processes of subsequent tower section cleaning, reinforcement, flaw detection, and even return to the factory. It ensures the shape and position accuracy of the tower sections and lays a solid foundation for the subsequent high-precision assembly of the tower.

[0042] The storage device of this invention forms a horizontal bidirectional limit at both ends of the tower section through a U-shaped positioning bracket, resisting the risk of lateral slippage and tilting of the tower section; a stable triangular support system is formed by the anti-tipping mechanism and the bottom support point, locking the degree of freedom of the top of the tower section to overturn; at the same time, the front limit of the positioning bracket and the rear limit of the lower connecting seat form a front-to-back bidirectional closed-loop constraint along the axial direction of the tower, which can effectively resist various external forces such as on-site wind load, hoisting aftershocks, and personnel contact, completely eliminating safety accidents such as tower section slippage, movement, and tilting. The structure has high load-bearing rigidity and stable stress, and has sufficient safety redundancy for long-term storage, fully meeting the safety production requirements of wind power construction sites.

[0043] The storage device of this invention adopts an integrated prefabricated modular structure, with no complex and easily damaged parts. It requires no welding or secondary processing on site, and can quickly complete the assembly, size adjustment and array arrangement of the device. The installation and adjustment of the anti-tipping mechanism can be completed by a single person without the assistance of large equipment. The telescopic load-bearing frame can be folded and retracted, making it convenient for relocation and transportation. It can be reused across projects without the need to customize special storage equipment for different projects, which greatly reduces equipment investment costs and on-site installation and dismantling time, effectively shortens the construction preparation cycle, and perfectly adapts to the construction needs of wind power projects with multiple work sites and fast turnover.

[0044] The present invention also provides a method for storing multi-type mixed tower trays, comprising the following steps: S1: Horizontally lay out the telescopic load-bearing frame 1 to the preset position on the wind turbine platform according to the tower plate specifications, and build a modular load-bearing base; S2: Adjust the telescopic beam 11 to achieve stepless lateral telescopic expansion and contraction, adapt to different diameter tower plates 5, and synchronously drive the support platform 2 to align. S3: The sliding telescopic longitudinal beam 12 enables stepless longitudinal adjustment, adapting to tower plates of different widths 5 and ensuring precise support spacing; S4: Hoist the tower plate 5 so that its end is embedded into the positioning bracket 3 to complete the bottom horizontal limit and ground isolation protection; S5: Raise the telescopic rod 41 upward around the lower connecting seat 43 to adjust the length to match the height of the tower plate 5; S6: Adjust the 42-degree angle of the chuck to engage the top of the tower plate 5, forming a flexible clamp and top limit; S7: Locking telescopic rod 41, together with tower plate 5 and telescopic load-bearing frame 1, forms a stable triangular support, completing safe storage in all dimensions.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
