Description

Technical Field

[0001] This utility model belongs to the field of storage tooling technology, and in particular relates to a quick-assembly modular tooling rack for fans. Background Technology

[0002] Wind turbines, as core equipment for converting wind energy into electricity, are widely used in wind farms and are key devices for achieving sustainable energy development. They capture wind energy through a rotor, transmit it to a generator via a transmission system, and thus generate electricity. Wind turbines consist of numerous complex components, among which the turbine tower is an indispensable and crucial part. The main function of the turbine tower is to support the rotor, nacelle, and other components at a certain height to obtain more stable and powerful wind energy. Because their height can typically reach tens or even hundreds of meters, and their weight is considerable, the storage of the tower requires specific storage racks to ensure safety and order. Suitable storage racks not only effectively protect the turbine tower from damage during storage but also make efficient use of storage space, facilitating subsequent transportation and installation.

[0003] Existing storage racks for turbine towers are primarily constructed from simple steel plates. To ensure sufficient load-bearing capacity to support the heavy tower, these steel plates are solid. In use, the steel support plates are first placed in their designated positions, and then the tower is smoothly placed onto the support plates using a lifting device. However, this type of storage rack has several drawbacks. Because the steel support plates are solid, the entire rack is extremely heavy and difficult to assemble and disassemble. During transportation, the heavy rack requires significant resources, increasing transportation costs and placing high demands on the load-bearing capacity of transport vehicles and road conditions, leading to transportation inconvenience.

[0004] Therefore, there is an urgent need to design a quick-assembly modular tooling frame for wind turbines to solve the problems mentioned above. Utility Model Content

[0005] To address the technical problems mentioned in the background section regarding the excessive weight and difficulty in disassembling existing tooling frames, a quick-assembly modular tooling frame for fans is provided.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a quick-assembly modular tooling frame for fans is as follows: A quick-assembly modular tooling frame for supporting wind turbine towers includes an arc-shaped support frame. The side walls of the arc-shaped support frame are provided with multiple vertical horizontal and longitudinal reinforcing bars. The inner edge of the arc-shaped support frame is also provided with a first reinforcing component. The first reinforcing component includes a clearance position to avoid the connection between the horizontal and longitudinal reinforcing bars and the arc-shaped support frame. The quick-assembly modular tooling frame for wind turbines also includes a second reinforcing component. The second reinforcing component passes through the longitudinal reinforcing rod and is parallel to the extension direction of the transverse reinforcing rod. The second reinforcing component can move laterally, thereby engaging with the arc-shaped support frame to improve the support strength of the longitudinal reinforcing rod.

[0007] Furthermore, the curved support frame includes: The base includes an arc-shaped section for supporting the wind turbine tower. The edges of the base are provided with extensions perpendicular to the base surface so that the cross-section of the base is "I" shaped. The insertion rod is set on the base and has a insertion hole for insertion and mating with the second reinforcing component.

[0008] Furthermore, the second reinforcement component includes: A sliding rod is inserted through the longitudinal reinforcing rod and is parallel to the extension direction of the transverse reinforcing rod, allowing the sliding rod to move laterally. The locking block is set on the sliding rod and can move together with the sliding rod. Multiple locking blocks are set at intervals. The locking blocks can follow the movement and be inserted into the socket on the plug rod.

[0009] Furthermore, the second reinforcing component also includes a locking rod, which is rotatably mounted on the arc-shaped support frame. The sliding rod has a positioning hole, and the locking rod can rotate into the positioning hole to lock the sliding rod.

[0010] Furthermore, the substrate also includes a T-shaped block, which is disposed on the outside of the substrate. The long end of the T-shaped block is disposed on the extension of the substrate and extends in a direction away from the substrate. The locking rod is rotatably disposed on the short end of the T-shaped block, and the positioning hole is disposed on the part of the sliding rod that extends out of the substrate.

[0011] Furthermore, a sliding groove is provided on the extension, and the T-shaped block can slide in the sliding groove so that the sliding rod approaches or moves away from the positioning hole located on the sliding rod.

[0012] Furthermore, the substrate also includes a buffer pad, which is laid on the outside of the arc-shaped part and abuts against the wind turbine tower.

[0013] Furthermore, a support seat is provided on the inner side of the extension at the bottom of the base, and multiple bolts are threadedly connected to the support seat on both sides and in the middle.

[0014] Furthermore, the bottom of the buffer pad fits into the top of the arc-shaped support frame, and multiple screws are threaded to both the front and rear sides of the top of the buffer pad. The bottom ends of the multiple screws penetrate the buffer pad and are threaded to the arc-shaped support frame.

[0015] Furthermore, the first reinforcing component includes two sets of reinforcing ribs, which are spaced apart to form a clearance for avoiding the transverse reinforcing rod and the longitudinal reinforcing rod.

[0016] This utility model of a quick-assembly modular wind turbine jig has the following advantages: By incorporating clearance spaces in the first reinforcing component, it effectively protects critical connection points of the arc-shaped support frame, such as welds, and avoids localized stress accumulation caused by additional reinforcing structures, thus significantly extending its service life. Furthermore, the second reinforcing component can be quickly inserted laterally on-site and interlocked with the main structure, greatly improving assembly efficiency. Therefore, this quick-assembly modular wind turbine jig adopts a modular design, reducing the weight of individual components, facilitating transportation and disassembly, effectively solving the problems of difficult transportation and high costs associated with traditional solid steel frames, and significantly improving longitudinal support stiffness, effectively preventing deformation or instability caused by the tower's own weight during storage.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 8 This utility model describes a quick-assembly modular tooling frame for fans.

[0022] This embodiment provides a quick-assembly modular tooling frame for supporting the wind turbine tower 100. Figure 1 This is a schematic diagram of the quick-assembly modular tooling frame for the wind turbine and the supporting wind turbine tower in this embodiment; Figure 2 This is a schematic diagram of the structure of the quick-assembly modular tooling frame for wind turbines in this embodiment. The quick-assembly modular tooling frame for wind turbines includes an arc-shaped support frame 1. The side wall of the arc-shaped support frame 1 is provided with a plurality of vertical transverse reinforcing rods 2 and longitudinal reinforcing rods 3. The inner edge of the arc-shaped support frame 1 is also provided with a first reinforcing component 4. The first reinforcing component 4 includes a clearance position 42 to avoid the connection between the transverse reinforcing rods 2 and longitudinal reinforcing rods 3 and the arc-shaped support frame 1. The quick-assembly modular tooling frame for wind turbines also includes a second reinforcing component 5. The second reinforcing component 5 passes through the longitudinal reinforcing rod 3 and is parallel to the extension direction of the transverse reinforcing rod 2. The second reinforcing component 5 can move laterally, thereby interlocking with the arc-shaped support frame 1 to improve the support strength of the longitudinal reinforcing rod 3.

[0023] Understandably, this quick-assembly modular jig for wind turbines, by incorporating a clearance 42 in the first reinforcing component 4, effectively protects critical connection points of the arc-shaped support frame 1, such as welds, and avoids localized stress accumulation caused by additional reinforcing structure coverage, thus significantly extending its service life. Furthermore, the second reinforcing component 5 can be quickly inserted laterally on-site and interlocked with the main structure, greatly improving assembly efficiency. Therefore, this quick-assembly modular jig for wind turbines adopts a modular design, reducing the weight of individual components, facilitating transportation and disassembly, effectively solving the problems of difficult transportation and high costs associated with traditional solid steel frames, and significantly improving longitudinal support stiffness, effectively preventing deformation or instability caused by the tower's own weight during storage.

[0024] Figure 3 This is a side view of the quick-assembly modular tooling frame for the fan in this embodiment; Figure 4 This is a schematic diagram of the structure of the base, buffer pad, and sliding rod in this embodiment.

[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the arc-shaped support frame 1 includes a base 11 and a plug rod 12. The base 11 includes an arc-shaped portion 111 for supporting the wind turbine tower 100. The edge of the base 11 is provided with an extension portion 112 perpendicular to the surface of the base 11, so that the cross-section of the base 11 is "I" shaped. The plug rod 12 is provided on the base 11 and has a plug hole 121 for plugging and engaging with the second reinforcing component 5.

[0026] Understandably, the "I"-shaped cross-section structure possesses excellent bending resistance, effectively reducing material usage and overall weight while ensuring load-bearing capacity, thus contributing to lightweight design; furthermore, this structure enhances scalability. The meticulously designed insertion hole 121 on the insertion rod 12 provides precise positioning and a stable insertion interface for the locking block 512 of the second reinforcing component 5, ensuring a secure and reliable connection. The arc-shaped portion 111 fits tightly against the outer wall of the wind turbine tower 100, resulting in uniform load distribution and effectively avoiding localized pressure loss caused by point contact.

[0027] Figure 5 This is an exploded view of the quick-assembly modular tooling frame for the wind turbine in this embodiment; Figure 6 This is an exploded view of the base, buffer pad, and sliding rod in this embodiment. In this embodiment, as Figure 5 and Figure 6 As shown, the arc-shaped support frame 1 is composed of two bases 11 spliced ​​together, and has a plug hole for installing the plug rod. The plug rod 12 is inserted into the plug hole to connect the two bases 11.

[0028] Figure 7This is a schematic diagram of a partial structure of the quick-assembly modular tooling frame for fans of this utility model; Figure 8 for Figure 7 A magnified view of a portion of point A in the middle.

[0029] Furthermore, such as Figure 7 and Figure 8 As shown, the second reinforcing component 5 includes a sliding rod 51 and a locking block 512. The sliding rod 51 passes through the longitudinal reinforcing rod 3 and is parallel to the extension direction of the transverse reinforcing rod 2. The sliding rod 51 can move laterally. The locking block 512 is disposed on the sliding rod 51 and can move together with the sliding rod 51. Multiple locking blocks 512 are disposed at intervals. The locking blocks 512 can follow the movement and be inserted into the insertion hole 121 on the insertion rod 12.

[0030] Understandably, the sliding rod 51 penetrates the longitudinal reinforcing rod 3 and is parallel to the transverse reinforcing rod 2, constructing a spatial cross-reinforcing system that significantly enhances the overall rigidity and resistance to lateral deformation of the longitudinal reinforcing rod 3. Multiple locking blocks 512 are arranged at intervals to effectively distribute the force, preventing excessive load on a single connection point and thus improving connection safety. The insertion method between the locking blocks 512 and the insertion holes 121 eliminates the need for bolts 62, enabling rapid assembly, simplifying operation, and saving manpower and time. This design supports tool-free rapid installation and disassembly on-site, meeting the needs of frequent relocation of wind power equipment storage sites. The structure has strong interlocking properties, making it difficult to loosen even under vibration conditions, ensuring long-term reliability.

[0031] Furthermore, the second reinforcing component 5 also includes a locking rod 52, which is rotatably mounted on the arc-shaped support frame 1. The sliding rod 51 is provided with a positioning hole 511, and the locking rod 52 can rotate into the positioning hole 511 to lock the sliding rod 51.

[0032] Understandably, the locking lever 52 mechanism effectively prevents the sliding lever 51 from accidentally slipping or disengaging during use, thus significantly improving the safety and stability of the connection. The rotating locking lever 52 is easy to operate; locking or unlocking can be completed simply by manual rotation, without the need for additional tools. The precise fit between the positioning hole 511 and the locking lever 52 constitutes a mechanical self-locking structure, providing reliable anti-loosening functionality, making it particularly suitable for complex outdoor environments such as wind, sand, and vibration. Furthermore, this mechanism also improves the dynamic stability of the entire tooling frame when bearing heavy tower sections, effectively preventing structural failure caused by the accumulation of minute displacements.

[0033] Furthermore, the base 11 also includes a T-shaped block 113, which is disposed on the outside of the base 11. The long end of the T-shaped block 113 is disposed on the extension 112 of the base 11 and extends in a direction away from the base 11. The locking rod 52 is rotatably disposed on the short end of the T-shaped block 113, and the positioning hole 511 is disposed on the part of the sliding rod 51 that extends out of the base 11.

[0034] Understandably, the T-block 113 serves as a support for the locking rod 52, with a robust structure and a clear force transmission path, effectively transferring the locking force to the main frame. Pushing the locking rod 52 outwards avoids interference with other internal structures, facilitating manual operation and daily maintenance. The positioning hole 511 is located on the exposed section of the sliding rod 51, allowing for easy observation of alignment and insertion status, thereby improving installation accuracy and visibility. The overall structural layout is scientifically sound and reasonable, emphasizing both functionality and ergonomic design, making it highly suitable for large-scale application.

[0035] Furthermore, such as Figure 7 As shown, a sliding groove 114 is provided on the extension 112, and the T-shaped block 113 can slide in the sliding groove 114 so that the sliding rod 51 approaches or moves away from the positioning hole 511 located on the sliding rod 51.

[0036] Understandably, the fine-tuning alignment between the locking rod 52 and the positioning hole 511 effectively solves the docking problem caused by machining errors or assembly deviations; the sliding adjustment mechanism significantly improves the assembly tolerance rate, and locking can be successfully achieved even with slight dimensional deviations; this design can flexibly adapt to the assembly needs of different batches or slightly different components, greatly enhancing the versatility and interchangeability of the tooling fixture; in addition, it also helps to accurately control the preload, further improving the overall connection quality and safety redundancy.

[0037] Furthermore, the substrate 11 also includes a buffer pad 13, which is laid on the outside of the arc-shaped portion 111 and abuts against the wind turbine tower 100.

[0038] Understandably, the buffer pad 13 can effectively absorb the impact energy when the tower is placed, thereby reducing the damage to the tower surface coating or base material caused by rigid collisions; it can also prevent scratches, indentations and other problems caused by direct metal-to-metal contact, ensuring the integrity of the tower's appearance; in addition, the buffer pad 13 can also increase the coefficient of friction, preventing the tower from sliding or tipping over on the tooling rack, further improving the safety of storage.

[0039] Preferably, the material of the cushioning pad 13 can be a highly elastic material such as rubber or polyurethane, which is not only wear-resistant but also has good weather resistance.

[0040] Furthermore, a support seat 61 is provided on the inner side of the extension 112 at the bottom of the base 11, and multiple bolts 62 are threadedly connected to the support seat 61 on both sides and in the middle.

[0041] Understandably, the reinforced design of the support base 61 effectively enhances the strength of the bottom structure, preventing the base 11 from bending or collapsing under heavy loads. The multi-point bolt connection 62 not only provides adjustable height and levelness but also adapts to uneven ground conditions. Fine-tuning of the bolts 62 allows for precise control of the support height, ensuring the curved support surface is in an ideal position, thus enabling stable tower placement. Furthermore, this connection method is detachable, facilitating disassembly during transportation and storage, fully aligning with the design concept of quick assembly and disassembly. Overall, this design significantly enhances the stability of the entire machine, performing particularly well on soft soil foundations or temporary sites.

[0042] Furthermore, such as Figures 2-7 As shown, the bottom of the buffer pad 13 is attached to the top of the arc-shaped support frame 1, and multiple screws 14 are threaded to both the front and rear sides of the top of the buffer pad 13. The bottom ends of the multiple screws 14 pass through the buffer pad 13 and are threaded to the arc-shaped support frame 1.

[0043] Understandably, the screw 14 connection method ensures that the buffer pad 13 is firmly fixed, preventing it from shifting or falling off during use; the multi-point fixing on both the front and rear sides forms a bidirectional constraint, effectively resisting the shear force generated by the rolling or sliding of the tower; the through-type design of the screw 14 makes the connection strong and not easy to loosen due to vibration or temperature changes; maintenance and replacement are convenient, and the buffer pad 13 can be replaced as a whole simply by unscrewing the screw 14, thereby extending the overall service life of the tooling frame; maintaining the integration of the buffer layer and the support structure improves the overall coordination and safety of the system.

[0044] Furthermore, such as Figure 6 As shown, the first reinforcing component 4 includes two sets of reinforcing ribs 41, which are spaced apart to form a clearance position 42 for avoiding the transverse reinforcing rod 2 and the longitudinal reinforcing rod 3.

[0045] Understandably, the split arrangement of stiffener 41 not only strengthens the structure but also preserves the necessary space for maintenance and inspection; the design of the clearance position 42 effectively avoids the welding heat-affected zone being covered, which is beneficial for subsequent flaw detection and anti-corrosion treatment; the split structure reduces the risk of stress concentration and improves the fatigue life of the joint area; the manufacturing process is simplified, and it can be directly installed through standard welding process without the need for complex openings or embedded structures; while enhancing the edge stiffness, it does not affect the integrity of the main load-bearing structure, achieving the optimization goal of "strengthening without obstruction".

[0046] The working principle of this quick-assembly modular tooling frame for wind turbines is as follows: When storing the tower, first select an appropriate number of tooling racks according to the length of the tower. After arranging multiple tooling racks at equal intervals, place the tower on top of multiple arc-shaped support frames 1. Above the arc-shaped support frames 1, two arc-shaped support frames 1 with I-shaped cross sections constitute the main structure of the tooling rack.

[0047] When assembling the tooling frame, first fix the insert rod 12 to the arc-shaped support frame 1. Then, install the sliding rod 51 so that the sliding rod 51 located on the inner wall of the arc-shaped support frame 1 can slide to one side. Since multiple locking blocks 512 are fixed to one side of the top of the sliding rod 51, the locking blocks 512 will move together with the sliding rod 51 until the multiple locking blocks 512 are simultaneously inserted into the corresponding insertion holes 121 of the insert rod 12, which to a certain extent restricts the insert rod 12 and the sliding rod 51. Then, insert the two locking rods 52 into the positioning holes 511 opened on the two sliding rods 51 respectively, fix the position of the two sliding rods 51, thereby completing the quick fixation of the arc-shaped support frame 1 and realizing the convenient assembly of the tooling frame.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
