Description

Technical Field

[0001] This application relates to the field of wind turbine blade cutting equipment, and more specifically, to a fixed structure and a cutting machine. Background Technology

[0002] Wind turbine blades are one of the core components of wind turbines, accounting for about 15%-20% of the total cost of the wind turbine. Their design directly affects the performance and efficiency of the wind turbine.

[0003] After long-term use, wind turbine blades may become damaged due to external environmental factors, corrosion of the blades themselves, and other environmental issues. The damaged blades need to be recycled. However, wind turbine blades are very long, making overall transportation difficult. Therefore, cutting the blades before transport can prevent transportation difficulties. Currently, cutting machines are generally used for this purpose. For example, a cutting device for processing finger-jointed boards disclosed in application number 202123084984.0 only has one fixing method for the blades to be cut. Due to the long length of the wind turbine blades, blade misalignment occurs during cutting, leading to instability and affecting cutting efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, this application provides a fixing structure and a cutting machine, which can solve the problem that the long length of the fan blades causes the fan blades to deviate during cutting, resulting in instability and affecting the cutting efficiency of the fan blades.

The baffles are provided with vertical clearance grooves at the cutting groove.

[0011] In one specific implementation, the pressing component includes two second cylinders, which are respectively fixedly connected to the cylinder rod ends of the two first cylinders, and pressing blocks are respectively fixedly connected to the cylinder rod ends of the two second cylinders.

[0012] On the other hand, the technical solution adopted by the embodiments of this application to solve its technical problem is: a cutting machine, including the above-mentioned fixing structure and cutting components.

Detailed Implementation

[0024] The technical solution in this application embodiment is to solve the problem that the long length of the aforementioned wind turbine blades causes blade misalignment during cutting, resulting in instability and affecting the cutting efficiency of the wind turbine blades. The overall approach is as follows:

[0025] Please see Figures 1-5 The technical solution adopted by the embodiments of this application to solve its technical problem is: a fixed structure, including a frame 110 and a fixed component 20.

[0026] Please see Figure 1 and Figure 2 The frame 110 has a cutting groove 111.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing component 20 includes a first movable positioning component 210, which is mounted on the frame 110 at one end of the cutting groove 111. The positioning end of the first movable positioning component 210 is also provided with a pressing component 240. A fixing plate 220 is fixedly connected to the frame 110 at the other end of the cutting groove 111. The fan blade to be recycled is placed on the frame 110, so that the part to be cut is located at the cutting groove 111. At this time, one side of the fan blade is in contact with the side of the fixing plate 220. Then, the first movable positioning component 210 is activated, moving to limit the fan blade between the fixing plate 220 and the first movable positioning component 210. Then, the pressing component 240 is activated, so that the pressing end of the pressing component 240 presses against the upper surface of the fan blade, thereby achieving the limiting of the fan blade. The first movable positioning component 210 and the fixed plate 220 cooperate to achieve the first limiting of the wind turbine blade, and then the pressing component 240 achieves the second limiting of the wind turbine blade, thereby improving the multi-dimensional limiting of the wind turbine blade, improving the stability of the wind turbine blade during cutting, and improving the cutting efficiency of the wind turbine blade.

[0028] A second movable positioning component 230 is installed on the side of the frame 110 away from the cutting groove 111. The second movable positioning component 230 includes a limiting plate 231, a movable plate 232, a long screw 233, and a handwheel 234. The limiting plate 231 is installed on the side of the frame 110 away from the cutting groove 111. The movable plate 232 is slidably connected to the upper surface of the frame 110. One end of the long screw 233 is fixedly connected to the handwheel 234, and the other end of the long screw 233 is screwed through the movable plate 232 and rotatably connected to the limiting plate 231. When the fan blade is placed on the frame 110 and there is contact between the fan blade and the limiting plate 231, the handwheel 234 is rotated, causing the long screw 233 to rotate, which in turn causes the movable plate 232 to move, confining the fan blade between the limiting plate 231 and the movable plate 232, thereby achieving a third point of positioning of the fan blade and further improving the stability of the fan blade during cutting.

[0029] The first movable positioning component 210 includes a mounting base 211, which is mounted on the frame 110 at one end of the cutting groove 111. Two first cylinders 212 are mounted on both sides of the mounting base 211 at the cutting groove 111. The cylinder rod ends of the two first cylinders 212 respectively movably pass through the mounting base 211 and are fixedly connected to baffles 213. The baffles 213 have vertical clearance grooves 2131 at the cutting groove 111. The pressing component 240 includes two second cylinders 241, which are fixedly connected to the cylinder rod ends of the two first cylinders 212 respectively. The cylinder rod ends of the two second cylinders 241 are fixedly connected to pressing blocks 242 respectively. When limiting the fan blades, the first cylinder 212 is activated, causing the baffle 213 to move and limit the fan blades between the fixed plate 220 and the baffle 213. Then the second cylinder 241 is activated, causing the lower block 242 to move down and position the second positioning point of the fan blades.

[0030] Please see Figures 1-5 The technical solution adopted by the embodiments of this application to solve its technical problem is: a cutting machine, including a fixed structure and a cutting component 30.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The cutting assembly 30 includes a movable component 310 and a cutting component 320. The movable component 310 is installed inside the frame 110, and the cutting component 320 is installed at the movable end of the movable component 310. A cutting blade 350 is installed at the driving end of the cutting component 320, and the cutting blade 350 is located inside the cutting groove 111. The movable component 310 drives the cutting component 320 to move. The movable component 310 drives the cutting component 320 to move, causing the cutting blade 350 to move within the cutting groove 111, thereby cutting the wind turbine blade.

[0032] A debris collection component 340 is installed at the bottom of the cutting blade 350. The movable component 310 includes a connecting seat 311, which is installed at the inner bottom of the frame 110. A movable seat 313 is slidably connected to the connecting seat 311. The cutting component 320 is installed on the movable seat 313. A third cylinder 312 is also installed on the connecting seat 311. The cylinder rod end of the third cylinder 312 is connected to the movable seat 313 and drives the movable seat 313 to move. Specifically, the cutting component 320... The system includes a drive motor 321, which is mounted on a movable base 313. The output end of the drive motor 321 is fixedly connected to a drive pulley 322. A driven pulley 323 is also rotatably connected to the movable base 313. A transmission belt 324 connects the drive pulley 322 and the driven pulley 323. The cutting blade 350 is fixedly connected to the driven pulley 323. A collection trough 341 with an open top is installed on the movable base 313. The bottom of the cutting blade 350 is located inside the collection trough 341. A connecting groove 342 is connected to the bottom of the collection trough 341. A fixing groove 343 with an open top is provided at the bottom of the frame 110. The material discharge point at the bottom of the connecting groove 342 extends to the opening of the fixing groove 343. Simultaneously, the third cylinder 312 and the drive motor 321 are activated. The third cylinder 312 drives the cutting blade 350 to move, and the drive motor 321 drives the cutting blade 350 to rotate, thereby realizing the cutting blade 350 moving and rotating at the same time, thus cutting off the fan blade.

[0033] When this application is used:

[0034] The fan blades to be recycled are placed on the frame 110, with the portion to be cut positioned at the cutting groove 111. At this point, one side of the fan blade contacts the side of the fixing plate 220. Then, the first moving positioning component 210 is activated, moving to limit the fan blade between the fixing plate 220 and the first moving positioning component 210. Next, the pressing component 240 is activated, causing its pressing end to press against the upper surface of the fan blade, thereby limiting the fan blade. Through the cooperation of the first moving positioning component 210 and the fixing plate 220, the first limiting of the fan blade is achieved. Then, the pressing component 240 achieves a second limiting of the fan blade, thereby improving the multi-dimensional limiting of the fan blade, enhancing the stability of the fan blade during cutting, and increasing the cutting efficiency of the fan blade.

[0035] It should be noted that the specific models and specifications of the first cylinder 212, the second cylinder 241, the third cylinder 312 and the drive motor 321 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and operating principle of the first cylinder 212, the second cylinder 241, the third cylinder 312 and the drive motor 321 are clear to those skilled in the art and will not be described in detail here.
