DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Embodiment 1, as Figure 1-Figure 5 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a special guard plate structure for protecting the trailing edge of the wind turbine blade hoisting, including a support column 1 and a support member 2 connected to the top thereof, a sliding member 3 connected to the top of the support member 2, the sliding member 3 is connected to a transmission member 4, and the transmission member 4 is connected to a wrapping member 5.

[0034] The sliding component 3 includes a rotating motor 301 connected to the bottom of the supporting member 2 , a threaded rod 302 is connected to the output end of the rotating motor 301 , and a threaded member 303 is threadedly connected to the threaded rod 302 . The supporting member 2 is provided with a transmission groove 304 .

[0035] The threaded member 303 is slidably connected to the inner wall of the transmission groove 304 , a sliding member 306 is connected to the top of the threaded member 303 , a sliding rail 305 is connected to the top of the support member 2 , the sliding rail 305 is arranged on both sides of the transmission groove 304 , and the sliding rail 305 is slidably connected to the bottom of the sliding member 306 .

[0036] The transmission component 4 includes an electric telescopic rod 401 connected to the top of the sliding member 306, a sliding bracket 402 is connected to the side of the sliding member 306, the sliding bracket 402 is provided with a sliding groove 404, the telescopic end of the electric telescopic rod 401 is connected to the transmission member 403, and the bottom of the transmission member 403 is connected to a connecting rod 405.

[0037] The connecting rod 405 is slidably connected to the inner wall of the sliding groove 404 , and the bottom of the connecting rod 405 is connected to the wrapping component 5 .

[0038] The specific working principle is: the device can effectively improve the stability of lifting and handling of raw materials such as blades. When in use, the device can make the flexible wrapping member 506 fit the curved surface of the blade side, so that the device is in full contact with the blade.

[0039] When the device is in use, the sliding component 3 on the top of the support 2 can drive the subsequent transport device to slide horizontally linearly, and the transmission component 4 structure perpendicular to the sliding component 3 can realize the longitudinal linear movement of the subsequent transport device, thereby achieving the lifting and transporting effect of the device.

[0040] During the transportation process, the winding roller 504 is driven to rotate by the transmission motor, so that the wrapping piece 506 on the winding roller 504 is released. At this time, the length of the wrapping piece 506 under the wrapping bracket 501 increases, causing the lowest point of the wrapping piece 506 to drop. At this time, the blade is placed inside the wrapping piece 506 so that the trailing edge of the blade is facing upward. At this time, the transmission motor 503 is rotated in the opposite direction. The rotation of the transmission motor 503 can make the winding roller 504 reel in and rotate, thereby shortening the length of the wrapping piece 506, and then driving the blade to rise upward. After rising to a certain height, the trailing edge of the blade facing upward contacts with the arc-shaped abutment piece 508, thereby completing the vertical lifting effect of the device. At this time, the sliding component 3 and the transmission component 4 can achieve the effect of driving the blade to be transported, so that the blade is moved to the correct position.

[0041] Embodiment 2, as Figure 1-Figure 5 As shown, in order to solve the existing problems, in the present embodiment, based on the same concept as the above-mentioned embodiment 1, the special guard plate structure for protecting the trailing edge of the wind turbine blade hoisting also includes: the wrapping component 5 includes a wrapping bracket 501 connected to the bottom of the connecting rod 405, the top of the wrapping bracket 501 is connected to a motor bracket 505, the motor bracket 505 is connected to a transmission motor 503, the output end of the transmission motor 503 is connected to a winding roller 504, the winding roller 504 is rotatably connected to a rotating bracket 502 on the side, and the rotating bracket 502 is connected to the top of the wrapping bracket 501.

[0042] The winding roller 504 is wound and connected with a wrapping member 506 , and a plurality of anti-skid pads 507 distributed at equal intervals are connected to the inner side of the wrapping member 506 . The bottom of the wrapping bracket 501 is connected with an arc-shaped abutting member 508 .

[0043] The wrapping components 5 are symmetrically arranged on both sides of the transmission component 4 , and one end of the wrapping member 506 away from the winding roller 504 is connected to the bottom of the wrapping bracket 501 .

[0044] The specific working principle is: this device can effectively improve the efficiency and stability of lifting and handling of blades. Compared with traditional devices, the structure of the flexible wrapping member 506 can reduce problems such as wear on the blade surface, thereby improving the handling stability of the device.

[0045] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
