[0031] The sling fixing mechanism 200 includes a reduction motor 210 and a sling 220 .
[0032] The reduction motor 210 is fixed on the upper side of the first side end of the sling support arm 110 , and a belt reel 230 is coaxially fixed to the output end of the reduction motor 210 .
[0033] The sling 220 is used to support the lower side of the wind turbine blade 400 , one end of the sling 220 is fixed to the second side end of the sling support arm 110 , and the other end of the sling 220 is fixed to the winding wheel 230 .
[0034] The present application adds a reduction motor 210 and a take-up wheel 230 to the support arm of the sling 220 of the original suction cup demolding tooling, and controls the motor 211 to drive the take-up wheel 230 to rotate forward and reversely, so as to accurately tighten and loosen the sling 220, making the whole process more convenient and efficient. This improvement not only greatly reduces the labor intensity of the operator, but also significantly improves the accuracy and safety of the operation. The application of the motor 211 makes the control of the sling 220 more flexible and the operation easier, thereby better adapting to the development trend of large-scale wind turbine blades 400 and meeting the higher requirements of the modern wind power industry for safety and efficiency. When the sling 220 is not in use, the sling 220 can be rolled up on the take-up wheel 230, which keeps the working environment clean and tidy, and also facilitates the storage and management of the sling 220.
[0035] In some embodiments, reference Figure 1 The reduction motor 210 specifically includes a motor 211 and a reduction box 212. The motor 211 is fixed on the upper side of the sling support arm 110. The output shaft of the motor 211 faces the first side end of the sling support arm 110. The reduction box 212 is fixed on the upper side of the sling support arm 110. The input shaft and output shaft of the reduction box 212 are perpendicular. The input shaft of the reduction box 212 is coaxially fixedly connected with the output shaft of the motor 211. The winding wheel 230 is coaxially fixed on the output shaft of the reduction box 212.
[0036] In order to realize the 90° turning and reduction transmission of the reduction box 212 , a helical gear reduction transmission mechanism is provided in the reduction box 212 . In other embodiments, a worm gear reduction transmission structure may also be provided in the reduction box 212 .
[0037] In some embodiments, a fixing member 240 is provided on one side of the first side end of the sling support arm 110, the belt reel 230 is located on the same side of the fixing member 240, and one end of the sling 220 is fixed on the fixing member 240. In order to facilitate the connection and disassembly between the sling 220 and the fixing member 240, the fixing member 240 includes a latch seat 241 and a latch 242, and one end of the sling 220 is fixed on the latch seat 241 through the latch 242.
[0038] In some embodiments, a forward and reverse control button is further included, which is used to control the forward and reverse rotation of the reduction motor 210, so as to control the forward and reverse rotation of the motor 211 to drive the sling 220 to tighten and loosen. The forward and reverse control button can transmit control signals to the reduction motor 210 in a wired or wireless manner.
[0039] In some embodiments, a control electrical cabinet 120 is disposed on the suction cup demolding tooling body 100 , and electronic components such as a power module, a control module, and a communication module are disposed in the control electrical cabinet 120 .
[0040] In some embodiments, the vacuum suction cup mechanism 300 includes two groups of vacuum suction cup assemblies symmetrically arranged on both sides of the sling fixing mechanism 200, each group of vacuum suction cup assemblies includes a clamp 310, a shoulder beam 320 and two vacuum suction cups 330, the clamp 310 is fixed to the outside of the suction cup demoulding tooling body 100, the shoulder beam 320 is arranged longitudinally, the middle part of the shoulder beam 320 is hinged to the lower part of the clamp 310, and the two vacuum suction cups 330 are respectively hinged to the lower part of both ends of the shoulder beam 320. The shoulder beam 320 of this embodiment can be swung up and down relative to the suction cup demoulding tooling body 100, and each vacuum suction cup 330 can be swung up and down relative to the shoulder beam 320, so that each vacuum suction cup 330 can be in contact with the surface of the wind turbine blade 400, thereby ensuring the adsorption effect of each vacuum suction cup 330.
[0041] In some embodiments, a lifting ear 311 is provided on the upper portion of each clamp 310 , and the lifting equipment lifts the suction cup demoulding tooling through the lifting ear 311 on the clamp 310 , so that the lifting force is better.
[0042] In some embodiments, both ends of the suction cup demolding tool body 100 are provided with brackets 130 extending laterally to both sides, and the suction cup demolding tool can be supported by the brackets 130 when not in use.
[0043] This embodiment can control the loosening, tightening and storage of the sling 220. The control of the loosening mode of the sling 220, the tightening mode of the sling 220 and the storage mode of the sling 220 are specifically as follows:
[0044] Loosening method of the sling 220: We have integrated forward and reverse control buttons in the system to achieve precise loosening operation of the sling 220. When the reverse control button is pressed, the motor 211 starts to rotate in the reverse direction, and drives the belt reel 230 to rotate counterclockwise through the reduction box 212. As the belt reel 230 rotates in the reverse direction, the sling 220 wound on the belt reel 230 is gradually loosened, so that the length of the sling 220 increases, which is convenient for further operation and adjustment. This design ensures that the loosening process of the sling 220 can be achieved by simple button operation, which is easy to operate and highly accurate.
[0045] Tightening method of the sling 220: Before tightening the sling 220, the sling 220 needs to be loosened to a suitable length that can support the blade. The specific steps are as follows: First, the motor 211 is controlled to rotate in the opposite direction by the reverse control button to loosen the sling 220 to the required length, and then one end of the sling 220 is firmly fixed to the latch seat 241 at the second end of the sling support arm 110 through the latch 242 to ensure that the sling 220 will not slide or shift during the tightening process. Next, press the forward control button to start the motor 211 to rotate forward, driving the winding wheel 230 to rotate clockwise. As the winding wheel 230 rotates, the sling 220 is gradually tightened, supporting and fixing the bottom end of the wind turbine blade 400 at a predetermined position. The entire process is achieved through the forward and reverse control buttons of the motor 211, ensuring the precise tightening of the sling 220, while also enhancing the safety and stability of the operation.
[0046] Storage method of the sling 220: When the sling 220 is not in use, in order to facilitate storage and keep the working environment clean, we have designed a storage method for the sling 220. The specific operation is: press and hold the forward control button of the motor 211 to make the motor 211 continue to rotate forward, driving the take-up wheel 230 to wind the sling 220 around the take-up wheel 230 in a winding manner. As the motor 211 rotates, the sling 220 is wound around the take-up wheel 230 layer by layer until it is wound around the take-up wheel 230. At this time, release the forward control button, the motor 211 stops running, and the sling 220 is stored. This design not only facilitates the storage of the sling 220, but also effectively prevents the sling 220 from being scattered and damaged when not in use, thereby improving the management efficiency and service life of the overall equipment.
