Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to a wind turbine blade extension tooling. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. During the production process of wind turbine blades, the wind turbine blades need to be extended.

[0003] In the prior art, the patent with announcement number CN218407685U discloses a positioning tool for extending wind turbine blades, including a wind turbine blade assembly, wherein the wind turbine blade assembly includes a root blade, a tip blade, and a structural adhesive resin; and a positioning heating mechanism, wherein the positioning heating mechanism includes a root clamp, two extension plates, and a plurality of electric heating wires. The overall tooling frame of the utility model is made of aluminum alloy, which is light in weight and easy to operate. The overall frame does not need to be redesigned according to different wind turbine blades. It only needs to tighten the metal panel with bolts, and the root blades and tip blades of different sizes on the same arc surface can be fixed with rubber sleeves through the tightened metal panel. Then, the root blades and tip blades are fitted and heated by the electric heating wires pre-embedded in the root clamp, tip clamp, and extension plate, so that the connection is heated in all directions, thereby improving the heating effect and heating efficiency and avoiding the phenomenon of quality defects caused by inadequate heating. The technical solution proposed in the aforementioned patent technology requires tightening two metal panels by tightening several bolts during the actual extension process of wind turbine blades, which is labor-intensive. Furthermore, multiple bolts also need to be tightened during disassembly, which is very inconvenient and reduces work efficiency. In view of this, the present application proposes a wind turbine blade extension tool. Utility Model Content

[0046] By providing the rectangular plates 504 , the movement of the two rectangular plates 504 can drive the two T-shaped plates 501 to move simultaneously.

[0047] Please pay attention to Figure 5 In a preferred embodiment, a dual-axis motor 505 is fixedly installed on the inner bottom wall of the rectangular cavity, and threaded columns 506 are fixedly installed at the two output ends of the dual-axis motor 505, and cylindrical thread grooves 507 are respectively threadedly connected to the outer surfaces of the two threaded columns 506 at the ends of the two rectangular plates 504.

[0048] By providing a dual-axis motor 505 , the rotation of the dual-axis motor 505 can drive the two rectangular plates 504 to move toward the middle or to both sides at the same time.

[0049] Please pay attention to Figure 5 In a preferred embodiment, a limit block 508 is fixed on the upper surface of the end of the rectangular plate 504, and a limit opening 509 extending into the interior of the rectangular cavity for the limit block 508 to slide is opened on the inner bottom wall of the fixed frame 100.

[0050] By providing the limiting block 508 and the limiting opening 509 , the stability of the rectangular plate 504 during movement is effectively guaranteed.

[0051] In this embodiment, by setting up a moving component 500, the wind turbine blade body 200 and the wind turbine blade extension body 300 can be quickly connected before the wind turbine blade body 200 and the wind turbine blade extension body 300 are connected, and the wind turbine blade body 200 and the wind turbine blade extension body 300 can be effectively supported, thereby ensuring the stability of the wind turbine blade body 200 and the wind turbine blade extension body 300 during hot pressing connection, and ensuring the quality of the wind turbine blade after connection.

[0052] Working principle: Before connecting the wind turbine blade body 200 and the wind turbine blade extension 300, the tool can place the wind turbine blade body 200 and the wind turbine blade extension 300 on two support seats 503 on two T-shaped plates 501 respectively, and start the dual-axis motor 505. The rotation of the dual-axis motor 505 drives the two threaded columns 506 to rotate at the same time. The rotation of the threaded column 506 drives the two rectangular plates 504 to move toward the middle at the same time under the action of the cylindrical thread groove 507, thereby driving the wind turbine blade body 200 and the wind turbine blade extension 300 to move toward the middle at the same time, realizing The wind turbine blade body 200 and the wind turbine blade extension 300 can be quickly connected, and the wind turbine blade body 200 and the wind turbine blade extension 300 can be effectively supported during hot pressing connection, thereby ensuring the stability of the wind turbine blade body 200 and the wind turbine blade extension 300 during hot pressing connection, and ensuring the quality of the wind turbine blade after connection. At the same time, the angle of the wind turbine blade body 200 and the wind turbine blade extension 300 can be adjusted under the action of the hydraulic rod 502, so that the connection between the wind turbine blade body 200 and the wind turbine blade extension 300 can be fully aligned. The quality of the wind turbine blade after leveling is further guaranteed. At the same time, when the wind turbine blade body 200 is connected to the wind turbine blade extension body 300, the wind turbine blade body 200 can be connected to the ends of the wind turbine blade extension body 300 first, and then the driving motor 403 is started. The rotation of the driving motor 403 drives the rotating rod 406 to rotate, and the rotation of the rotating rod 406 drives the two active bevel gears 407 to rotate. The rotation of the active bevel gear 407 drives the driven bevel gear 408 and the bidirectional screw 405 to rotate, thereby driving the two bidirectional screws 405 to rotate synchronously. The rotation drives the two lifting plates 401 of a strip-shaped opening to move toward the middle at the same time, thereby driving the two metal connecting frames 402 to move toward the middle at the same time, effectively clamping and fixing the connection between the wind turbine blade main body 200 and the wind turbine blade extension body 300, and hot-pressing the connection between the wind turbine blade main body 200 and the wind turbine blade extension body 300 through the electric heating plate in the metal connecting frame 402, so that the tooling can quickly and effectively fix and connect the connection between the wind turbine blade main body 200 and the wind turbine blade extension body 300, thereby effectively improving work efficiency.
