Technical Field
[0001] The present invention relates to the technical field of wind power generation, and particularly to an automatic laying equipment for the web of a wind turbine blade. Background Art
[0002] The manufacturing technology of wind turbine blades is developing rapidly towards the direction of large-scale, lightweight and intelligent. As a key load-bearing component inside the wind turbine blade, the main function of the web is to connect the upper and lower skins, transfer shear forces and share part of the bending moment, so as to maintain the overall structural stiffness and stability of the blade. The laying quality of the web not only directly affects its own mechanical properties, but also plays a decisive role in the strength, stiffness and fatigue life of the entire blade. Especially in large blades, the length of the web increases and the shape is complex, which puts higher requirements on the consistency, accuracy and automation level of the laying process. Therefore, the stability and efficiency of the web laying quality have become one of the important links restricting the further improvement of the wind turbine blade manufacturing technology.
[0003] However, the current web laying equipment generally has problems such as large occupied space, heavy structure and being not conducive to a reasonable production layout. And most of them only have a single laying function and still rely on manual handling and transfer of materials, resulting in low overall production efficiency and long cycle. In addition, the cloth used for the web usually has a gradually changing width, and its shape has high matching requirements with the laying path. The existing equipment is difficult to achieve precise laying of the gradually changing cloth and cannot accurately position it in the specified area of the mold, thus affecting the web laying quality and directly affecting the structural strength and service life of the wind turbine blade. Summary of the Invention
[0004] The purpose of the present invention is to provide an automatic laying equipment for the web of a wind turbine blade, which has the advantages of small occupied space, light structure and flexible operation. It not only has an efficient automatic laying function, but also can realize automatic transfer of materials, effectively improving production efficiency and shortening the production cycle. At the same time, it can flexibly adapt to the change of the width of the web mold and accurately lay the cloth with a gradually changing width to the specified area of the mold, thus significantly improving the web laying quality and further enhancing the overall structural strength and service life of the wind turbine blade.

The dynamic centroid balance component can automatically detect the tilt state of the platform and automatically adjust the position of the counterweight to prevent uneven structural load caused by platform tilt, eliminating the need for large mechanical auxiliary support and improving operation flexibility. By sliding and fitting the anti-derailment wheel component with the edge of the web mold, derailment during operation is prevented, ensuring the stability and positioning accuracy of the device under high load conditions, which is beneficial for long-distance continuous cloth laying. The telescopic cloth feeding component can not only automatically lay the cloth but also expand and contract along the width direction of the web mold to automatically adjust the cloth boundary coverage area, adapt to different web mold profiles and width changes, and can synchronize cloth laying and width adjustment, effectively improving the efficiency and accuracy of cloth release and positioning, ensuring the efficiency and consistency of lamination, reducing human intervention factors, reducing errors, and reducing the risk of wrinkles and bubbles. Therefore, the automatic laminating device for the web of a wind turbine blade has the advantages of small occupied space, light structure, and flexible operation. It not only has an efficient automatic laying function but also can realize automatic material transfer, effectively improving production efficiency and shortening the production cycle. At the same time, it can flexibly adapt to the change of the web mold width and accurately lay the cloth with a gradually changing width to the specified area of the mold, thus significantly improving the web lamination quality and further enhancing the overall structural strength and service life of the wind turbine blade.

[0034] Please refer to Figures 1 to 5 As shown, this embodiment provides an automated layup device for a wind turbine blade web, which includes a unilateral walking mechanism 1 and a material transfer mechanism 2. The unilateral walking mechanism 1 includes an I-beam track 11, a transmission drive assembly 12, an anti-derailment wheel assembly 13 and a support frame. The I-beam track 11 is fixedly installed on the ground and extends along one side of the web mold 100. The transmission drive assembly 12 is installed on the I-beam track 11, and the output end of the transmission drive assembly 12 is connected to the anti-derailment wheel assembly 13 for driving the anti-derailment wheel assembly 13 to move along the I-beam track 11. The anti-derailment wheel assembly 13 is slidably and fittingly connected to the edge of the web mold 100 for preventing the unilateral walking mechanism 1 from derailing. The support frame is fixedly erected on the anti-derailment wheel assembly 13 and can move synchronously with it. The material transfer mechanism 2 includes a cantilevered material platform 21, a telescopic fabric laying assembly 22 and a dynamic centroid balance assembly. The cantilevered material platform 21 straddles above the web mold 100, and one side of it is perpendicularly connected to the support frame and moves with it. The telescopic fabric laying assembly 22 is installed on the cantilevered material platform 21 and is arranged along the width direction of the web mold 100 for automatically laying the fabric and being able to automatically adjust the fabric boundary coverage area. The dynamic centroid balance assembly is arranged on the cantilevered material platform 21 for detecting the inclination state of the cantilevered material platform 21 and adjusting the counterweight position to maintain the attitude balance of the cantilevered material platform 21.
[0035] As Figure 1As shown in the figure, since the width of the web die 100 gradually changes and the bending moment is large, by setting up a unilateral walking mechanism 1, which only sets the I-beam track 11 and the transmission drive assembly 12 on one side of the web die 100 to drive the equipment to move, it can effectively reduce the occupied space of the equipment; by arranging the cantilevered material platform 21 across the web die 100, the cloth can be laid across, eliminating the need for a double-track support structure, reducing the structural complexity, and also enabling the automatic transfer of materials, reducing manual operations and shortening the production cycle; the dynamic centroid balance assembly can automatically detect the tilt state of the platform and automatically adjust the position of the counterweight to prevent uneven structural loads caused by platform tilt, eliminating the need for large machinery for auxiliary support and improving operation flexibility; by slidingly fitting the anti-derailment wheel assembly 13 with the edge of the web die 100, derailment during operation can be prevented, ensuring the stability and positioning accuracy of the equipment under high-load conditions, which is beneficial to the long-distance continuous laying of the cloth. The telescopic cloth-releasing assembly 22 can not only automatically lay the cloth, but also expand and contract along the width direction of the web die 100 to automatically adjust the cloth boundary coverage area, adapting to different profiles and width changes of the web die 100, enabling the cloth laying and width adjustment to be carried out simultaneously, effectively improving the efficiency and accuracy of cloth release and positioning, ensuring the efficiency and consistency of the laying layer, reducing the influence of human intervention factors, reducing errors, and reducing the risk of wrinkles and bubbles. Therefore, the automatic layering equipment for the wind turbine blade web has the advantages of small occupied space, light structure, and flexible operation. It not only has an efficient automatic laying function, but also can realize the automatic transfer of materials, effectively improving production efficiency and shortening the production cycle; at the same time, it can flexibly adapt to the width change of the web die 100, accurately lay the cloth with a gradually changing width to the designated area of the die, thus significantly improving the web layering quality, and further enhancing the overall structural strength and service life of the wind turbine blade.
[0036] Optionally, a plurality of fixing members can be arranged at intervals on the lower flange surface of the I-beam track 11 to fix it to the ground. Among them, the fixing members can be, but are not limited to, dowel pins, etc., and no specific limitation is made here.
[0037] As Figure 3 shown in the figure, specifically, the transmission drive assembly 12 includes a gear 121, a rack 122, and a transmission drive member 123. The rack 122 is installed on the I-beam track 11 and arranged along its length direction; the transmission drive member 123 is fixedly connected to the anti-derailment wheel assembly 13, and a gear 121 is provided at the output end of the transmission drive member 123. The gear 121 is meshed with the rack 122, and the transmission drive member 123 is used to drive the gear 121 to rotate to drive the anti-derailment wheel assembly 13 to move; among them, compared with transmission forms such as belts and chains, the transmission method of meshing the gear 121 and the rack 122 has high precision, fast response, and no slipping; the rack 122 is fixed to the I-beam track 11, saving space and not affecting the load-bearing and guiding functions of the track.
[0038] Optionally, the transmission drive member 123 may, but is not limited to, a servo motor or the like, and no specific limitation is made here. Using a servo motor can accurately control the rotation speed and facilitate the precise positioning of the platform.
[0039] In some alternative embodiments, the transmission drive assembly 12 further includes a speed reducer 124. The output end of the drive member is connected to the input end of the speed reducer 124, and the output end of the speed reducer 124 is connected to the gear 121. By providing the speed reducer 124 between the transmission drive assembly 12 and the gear 121, the output speed of the transmission drive assembly 12 can be effectively reduced and the transmission torque can be increased, ensuring the smooth and precise operation of the anti - derailment wheel assembly 13 on the I - beam track 11, which helps to improve the laying accuracy and load - bearing capacity of the equipment. At the same time, the speed reducer 124 can also reduce the operating load of the drive member, extend its service life, and improve the operating stability and maintenance convenience of the equipment.
[0040] As Figure 2 shown, in some embodiments, the support frame includes at least two vertically arranged columns 14. The lower end of each column 14 is connected with an anti - derailment wheel assembly 13, and the upper end is perpendicularly connected to the cantilever material platform 21. The anti - derailment wheel assembly 13 can drive the support frame to reciprocate along the I - beam track 11. Among them, multiple vertical columns 14 jointly support the cantilever platform, which can evenly share the platform load, reduce the problems of inclination or structural stress concentration caused by single - point suspension, and improve the overall operating stability.
[0041] As Figure 4 shown, in some alternative embodiments, the anti - derailment wheel assembly 13 includes an I - beam traveling wheel set 131 and a single - side anti - rollover wheel set 132. The I - beam traveling wheel set 131 is installed at the lower end of the column 14 and is in rolling contact with the I - beam track 11, which is used to support the equipment and clamp the upper flange of the I - beam track 11. The single - side anti - rollover wheel set 132 is installed on the side of the column 14 and is in rolling contact with the edge of the web die 100, which is used to resist the lateral offset force during the operation of the I - beam traveling wheel set 131. Among them, the anti - derailment wheel assembly 13 adopts a multi - anti - derailment wheel set structure of the I - beam traveling wheel set 131 and the single - side anti - rollover wheel set 132, where the I - beam traveling wheel set 131 is used for load - bearing and track guidance to ensure the smooth operation of the equipment along the track. The single - side anti - rollover wheel set 132 is in rolling fit with the edge of the web die 100, which can effectively offset the lateral offset force generated due to the operation of the equipment, prevent the equipment from tilting or rolling over, and effectively improve the operating stability and laying accuracy of the whole machine during the movement process.
[0042] Specifically, the I-beam traveling wheel set 131 includes traveling wheels 131a and pressing wheels 131b. The traveling wheels 131a are installed at the lower end of the column 14 and are in rolling contact with the upper flange surface of the I-beam track 11. The pressing wheels 131b are installed below the traveling wheels 131a and are in rolling contact with the lower flange surface of the I-beam track 11. The traveling wheels 131a and the pressing wheels 131b can clamp the upper flange surface of the I-beam track 11. The single-sided anti-rollover wheel set 132 includes upper pressing wheels 132a and side cutter wheels 132b. The upper pressing wheels 132a are arranged on the side of the column 14 and are in contact with the upper edge of the web die 100, and can press the web die 100 vertically downward to limit the vertical movement of the anti-drop wheel assembly 13. The side cutter wheels 132b are arranged on the side of the column 14 and are in contact with the side edge of the web die 100. Among them, the traveling wheels 131a and the pressing wheels 131b in the I-beam traveling wheel set 131 clamp the upper flange surface of the I-beam track 11 up and down, which can effectively prevent abnormal meshing between the gear 121 and the rack 122 during the traveling process, so that the equipment will not lift or shift even when accelerating, decelerating, vibrating or the local track is uneven. In the single-sided anti-rollover wheel set 132, the upper pressing wheels 132a are located on the side of the column 14 and are in rolling contact with the upper edge of the web die 100, providing a vertical pressing force for the web die 100, resisting the web die 100, and restricting the vertical floating of the equipment during operation. The side cutter wheels 132b are arranged on the side of the column 14 and are in rolling contact with the side edge of the web die 100, effectively resisting the lateral offset force during operation, ensuring that the laying equipment runs stably in contact with the web die 100, and can also improve its operation accuracy and operation reliability.
[0043] In order to further ensure the stability of the cantilever when it expands and contracts and the load changes, in some embodiments, the dynamic centroid balance component includes an inclination sensor and a counterweight adjustment member. The inclination sensor is installed on the cantilever material platform 21, and the output end of the inclination sensor is connected to the counterweight adjustment member. The counterweight adjustment member can adjust the position of its own counterweight block according to the detection result of the inclination sensor. When the inclination sensor detects that the inclination angle of the cantilever material platform 21 exceeds the set normal range value, it can drive the counterweight block in the counterweight adjustment member to move in the direction opposite to the inclination angle until the inclination sensor feedbacks that the inclination angle of the cantilever material platform 21 returns to the normal range. Therefore, the equipment can monitor the inclination change of the cantilever material platform 21 in real time, automatically adjust the center of gravity, realize real-time adaptive adjustment of the posture, avoid manual intervention, and save adjustment time.
[0044] Specifically, the dynamic centroid balance component further includes a control unit and a proximity switch. The inclination sensor is used to detect the inclination angle of the cantilever material platform 21 in real time and feedback the detection result to the control unit. The control unit calculates the required compensation torque based on the received inclination data and controls the counterweight block in the counterweight adjustment component to move in the opposite direction of the inclination direction for attitude correction. The proximity switch is used to detect whether the counterweight block has moved to the preset target position and feedback the position status to the control unit. After the proximity switch confirms that the counterweight block has reached the position, the inclination sensor continues to monitor the inclination angle of the cantilever platform. When the detected angle returns to the set normal range, the control unit controls the system to maintain the current counterweight state and drives the cantilever platform to enter the normal operation state. Among them, the counterweight adjustment component includes a counterweight block and an electric push rod. The electric push rod is electrically connected to the control unit and can drive the counterweight block to move precisely along the set direction under the command of the control unit to realize the real-time adjustment of the platform centroid.
[0045] As Figure 5 shown, in some embodiments, the telescopic fabric unwinding component 22 includes a linear lead screw assembly 221, a fabric roll shaft 222, and a fabric roll guide 223. The linear lead screw assembly 221 is arranged along the width direction of the web die 100. The fabric roll shaft 222 and the fabric roll guide 223 are both arranged in parallel with the linear lead screw assembly 221. The fabric roll shaft 222 is located below the linear lead screw assembly 221. The fabric roll guide 223 and the fabric roll shaft 222 are arranged at intervals along the length direction of the web die 100. The fabric roll shaft 222 is used to install and release the fabric. The fabric roll guide 223 is used to guide the fabric to spread along the length direction of the web die 100. The output end of the linear lead screw assembly 221 is connected to the fabric roll shaft 222 and is used to drive the fabric on the fabric roll shaft 222 to stretch along the width direction of the web die 100. Among them, the linear lead screw assembly 221 can drive the fabric roll shaft 222 to move along the width direction of the web die 100, control the fabric roll shaft 222 to flexibly stretch between different die widths, adapt to the change of the web die 100 from wide to narrow, realize the automatic spreading of the fabric across the die, eliminate the manual adjustment process, significantly improve the fabric spreading efficiency, save manpower, and is suitable for the laying of fabrics with gradually changing structures such as the webs of wind turbine blades. The fabric roll guide 223 is arranged along the length direction, which helps the fabric to maintain uniform tension and unfold during the release and spreading process, realizes the automatic release, positioning, and spreading of the fabric, prevents the deviation or wrinkling and stacking of the fabric laying path, improves the laying quality, and significantly improves the automation level and operation efficiency.
[0046] Specifically, the linear ball screw assembly 221 includes a lead screw 221a, a slider 221b, a lead screw driving member 221c, and a frame 221d. The frame 221d is arranged along the width direction of the web die 100. The lead screw 221a is disposed within the frame 221d, and they are arranged in parallel. The slider 221b is screwed onto the lead screw 221a. The slider 221b is connected to the fabric unwinding roller 222. The lead screw driving member 221c is installed at one end of the frame 221d, and the output end of the lead screw driving member 221c is connected to the lead screw 221a for driving the slider 221b on the lead screw 221a to slide along the width direction of the web die 100. Among them, the slider 221b is connected to the lead screw 221a by screwing, and the sliding process is stable without jitter, having high-precision positioning ability, which is beneficial to fine laying; the frame 221d provides support and installation position for the lead screw 221a and defines the overall movement direction.
[0047] Optionally, the lead screw driving member 221c can be, but is not limited to, a servo motor, and no specific limitation is made here.
[0048] More specifically, the telescopic fabric unwinding assembly 22 further includes a limiting member 224. The limiting member 224 is disposed on the fabric unwinding roller 222 and is located at one end of the fabric unwinding roller 222 in the length direction away from the single-side traveling mechanism 1 for restricting the telescopic range of the fabric unwinding roller 222. When the fabric unwinding roller 222 approaches the limit position, the unsupported side will sag, bend, or suffer from structural fatigue due to its own weight or the weight of the fabric; the setting of the limiting member 224 can effectively limit its maximum displacement range and avoid abnormal stress or deformation of the mechanical structure from the source.
[0049] Among them, the limiting member 224 can be, but is not limited to, a limiting baffle, and no specific limitation is made here.
[0050] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
