Description

Technical Field

[0001] The present invention relates to the technical field of fan blade recovery, and in particular to a cutting device and method for recovering fan blades. Background Art

[0002] Wind turbine blades are mostly made of glass fiber and polyester resin. Some high-end wind turbine blades contain carbon fiber with high recycling value. The carbon fiber is mainly distributed in the face plate and web of the main beam, and the web often contains a large amount of balsa wood. At the same time, the overall size of the wind turbine is large. When recycling, it usually needs to be cut and crushed before recycling.

[0003] For example, the Chinese patent with the announcement number CN219788468U discloses a device for cutting and separating the main beam and shell of retired wind turbine blades. The cutting power mechanism drives the cutting shaft and the cutting saw blade to rotate at high speed. At the same time, the water supply mechanism starts to work and sprays water to the cutting saw blade; the lifting power mechanism of the lifting mechanism drives the adjusting screw of the adjusting screw to rotate, so that the adjusting nut drives the chassis frame and the cutting fixed frame to descend, thereby slowly pressing down the cutting saw blade, and the cutting saw blade gradually cuts into the shell on both sides of the main beam, cutting and separating the shell from the main beam.

[0004] However, when recycling the main beam, the web and panel of the main beam are made of different materials, and it is difficult for existing equipment to accurately and continuously separate the web and panel of the main beam; if they are crushed together, material mixing will occur, affecting the recycling efficiency; and some main beam webs and panels have different resin systems, and different resins have different decomposition temperatures and chemical resistances.

[0027] like Figure 3 、 Figure 7 and Figure 8 As shown, the fixed cutting assembly 41 includes a cutting mounting frame 411 and a cutter 412, and the cutter 412 is fixedly mounted on the cutting mounting frame 411; The mobile slitting assembly 42 includes a slitting support frame 421, a slitting linear module 422, a slitting mounting plate 423 and a cutter 424.

[0028] The first cutter 412 and the second cutter 424 are water jets, which are mature commercially available equipment in this field.

[0029] In this embodiment, when the adjustable conveying mechanism 1, the lifting mechanism 2, the cutting positioning mechanism 3, and the cutting mechanism 4 are working normally, the movable linear module 121 drives the conveying support plate 122 to move horizontally, thereby driving the second roller conveyor 124 and the guide roller 10 to move horizontally through the second conveying support frame 123, so that the distance between the second roller conveyor 124 and the first roller conveyor 112 is smaller than the web width of the corresponding blade main beam 5; so that the web of the blade main beam 5 contacts the conveying rollers of the first roller conveyor 112 and the second roller conveyor 124, and at this time, the panel of the blade main beam 5 is located outside the guide roller 10; The roller conveyor 112 and the roller conveyor 2 124 drive the blade main beam 5 to be transported to the right. When passing through the cutter 1 412, the blade main beam 5 is cut by the cutter 1 412 along the position between the two webs. At the same time, the two sets of lifting linear modules 213 drive the extension mounting frame 214 to move vertically, thereby driving the extension mounting frame 214 to move vertically, so that the extension mounting frame 214 moves to the position facing between the two webs. The cylinder linear slide 212 drives the rotating arm 224 to move horizontally through the lifting linear module 213 and the extension mounting frame 214, so that the rotating arm 224 and the elastic lifting block 225 at the end of the rotating arm 224 are inserted between the two webs. The giving way cylinder 221 drives the synchronous block 222 to move. The synchronous block 222 synchronously drives the rotating arm 224 to rotate through the two connecting rods 223, so that the distance between the elastic lifting blocks 225 at the ends of the rotating arm 224 is increased. After the blade main beam 5 is cut, the lifting linear module 213 drives the rotating arm 224 and the elastic lifting block 225 to move vertically upward through the extension mounting frame 214; the upper web and the corresponding panel are lifted by the rotating arm 224 and the elastic lifting block 225, so that the panel corresponding to the upper web is just not in contact with the lower panel; the roller conveyor 112 and the roller conveyor 2 124 drive the lower web and the corresponding panel to move to the right; then the lifting linear module 213 drives the lower web and the corresponding panel to move to the right through the extension mounting frame 214 The movable rotating arm 224 and the elastic lifting block 225 move vertically downward. After the lower panel moves to the outside of the guide roller 10 and the upper web approaches the roller conveyor 112 and the roller conveyor 2 124, the cylinder linear slide 212 drives the lifting linear module 213, the extended mounting frame 214, the rotating arm 224 and the elastic lifting block 225 to move horizontally. Then, the lifting linear module 213 drives the extended mounting frame 214, the rotating arm 224 and the elastic lifting block 225 to move vertically upward without blocking subsequent transportation. The roller conveyor 112 and the roller conveyor 2 124 drive the web and the corresponding panel to move to the right. When they move to the position aligned with the positioning wheel 315, the spring 313 is in a compressed state in the initial state. The reset cylinders 316 on both sides drive the reset push plate 317 to contract, so that the reset push plate 317 is not in contact with the connecting plate 318. The spring 313 resets and drives the positioning mounting plate 314 to move horizontally under the limiting action of the guide rod 312, thereby driving the positioning wheel 315 to move horizontally and press against the outside of the panel. The position of the positioning wheel 315 is detected by the position sensor. The positioning wheel 315 is aligned with the web. The slitting linear module 422 drives the slitting mounting plate 423 and the second cutter 424 to move horizontally from the inside to the outside, thereby driving the laser distance sensor 321 on the slitting mounting plate 423 to move horizontally; the laser distance sensor 321 detects the distance corresponding to the corresponding position during the horizontal movement; in the initial state, the laser distance sensor 321 measures the distance to the web, the web is a plane, and the data measured by the laser distance sensor 321 is consistent; when the measurement position of the laser distance sensor 321 moves to the panel, the data measured by the laser distance sensor 321 will change; If the data measured by the laser distance sensor 321 changes suddenly, and the measured position is the top of the panel, then the upper side of the panel will converge inwardly toward the web. At this time, the slitting linear module 422 drives the slitting mounting plate 423 and the second cutter 424 to move, so that the output end of the second cutter 424 is aligned with the inner side of the top of the panel. As the data measured by the laser distance sensor 321 gradually increases, the upper side of the corresponding panel tilts toward the outer side of the web; when the laser distance sensor 321 measures the end cutting surface, the data of the laser distance sensor 321 remains unchanged; the distance where the corresponding laser distance sensor 321 measures the unchanged data is the thickness of the panel; the slitting linear module 422 drives the slitting mounting plate 423 and the second cutter 424 to move, so that the second cutter 424 moves to a position one panel thickness inside the positioning wheel 315 for cutting; After the panel and the web are cut, the panel falls onto roller conveyor three 132 and roller conveyor four 133, and the panel is driven to the right by roller conveyor three 132 and roller conveyor four 133 respectively, and roller conveyor one 112 and roller conveyor two 124 continue to drive the web to the right; thereby realizing the separation of the panel and the web.

[0030] Embodiment 3: In some embodiments, as Figures 1-8 As shown, as a preferred embodiment of the present invention, a blade main beam cutting method of a cutting device for wind turbine blade recovery comprises the following steps: Step 1: Move the linear module 121 to drive the conveying support plate 122, the second conveying support frame 123, the second roller conveyor 124 and the guide roller 10 to move horizontally, so that the distance between the second roller conveyor 124 and the first roller conveyor 112 is smaller than the web width of the corresponding blade main beam 5; and make the web of the blade main beam 5 contact with the conveying rollers of the first roller conveyor 112 and the second roller conveyor 124; Step 2: Roller conveyor 112 and roller conveyor 2 124 drive the blade main beam 5 to be transported to the right. When passing through cutter 1 412, the blade main beam 5 is cut by cutter 1 412 along the position between the two webs. At the same time, the two sets of lifting linear modules 213 drive the extension mounting frame 214 to move vertically, thereby driving the extension mounting frame 214 to move vertically, so that the extension mounting frame 214 moves to the position facing between the two webs. The cylinder linear slide 212 drives the rotating arm 224 to move horizontally through the lifting linear module 213 and the extension mounting frame 214, so that the rotating arm 224 and the elastic lifting block 225 at the end of the rotating arm 224 are inserted between the two webs. The giving way cylinder 221 drives the synchronous block 222 to move, and the synchronous block 222 synchronously drives the rotating arm 224 to rotate through the two connecting rods 223, so that the distance between the elastic lifting blocks 225 at the ends of the rotating arm 224 is increased. After the blade main beam 5 is cut, the lifting linear module 2 13 drives the rotating arm 224 and the elastic lifting block 225 to move vertically upward through the extended mounting frame 214; the upper web and the corresponding panel are lifted by the rotating arm 224 and the elastic lifting block 225 so that the panel corresponding to the upper web is just not in contact with the lower panel; the roller conveyor 112 and the roller conveyor 2 124 drive the lower web and the corresponding panel to move to the right; then the lifting linear module 213 drives the rotating arm 224 and the elastic lifting block 225 to move vertically downward through the extended mounting frame 214. After the lower panel moves to the outside of the guide roller 10 and the upper web approaches the roller conveyor 112 and the roller conveyor 2 124, the cylinder linear slide 212 drives the lifting linear module 213, the extended mounting frame 214, the rotating arm 224 and the elastic lifting block 225 to move horizontally, and then the lifting linear module 213 drives the extended mounting frame 214, the rotating arm 224 and the elastic lifting block 225 to move vertically upward; After the cam 314 is in the working state, the cam 315 is in the working state, and the cam 316 is in the working state, so that the cam 316 is in the working state, and the cam 316 is in the working state, so that the cam 316 is in the working state, and the cam 316 is in the working state, so that the cam 316 is in the working state, and the cam 316 is in the working state, so that the cam 316 is in the working state, and the cam 316 is in the working state. ; when the measuring position of the laser ranging sensor 321 moves to the panel, the data measured by the laser ranging sensor 321 will change; if the data measured by the laser ranging sensor 321 suddenly changes, the measured position at this time is the top of the panel, then the corresponding upper side of the panel converges toward the web; at this time, the slitting linear module 422 drives the slitting mounting plate 423 and the second cutter 424 to move, so that the output end of the second cutter 424 is aligned with the inner side of the top of the panel; if the data measured by the laser ranging sensor 321 gradually increases, the corresponding upper side of the panel tilts toward the outer side of the web; when the laser ranging sensor 321 measures the end cutting surface, the data of the laser ranging sensor 321 remains unchanged; the distance where the corresponding laser ranging sensor 321 measures the unchanged data is the thickness of the panel; the slitting linear module 422 drives the slitting mounting plate 423 and the second cutter 424 to move, so that the second cutter 424 moves to a position of one panel thickness inside the positioning wheel 315 for cutting; Step 4: After the panel and the web are cut, the panel falls onto roller conveyor three 132 and roller conveyor four 133, and the panel is driven to the right by roller conveyor three 132 and roller conveyor four 133 respectively, and roller conveyor one 112 and roller conveyor two 124 continue to drive the web to the right; thereby realizing the separation of the panel and the web.
