Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a web movable rib auxiliary angle adjustment tool. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of components such as blades, generators, towers, speed limit safety mechanisms, and energy storage devices. The blade is one of the core components of the wind turbine. The upper and lower shells of the blades are connected with leading edge webs and trailing edge webs, which are mainly used to support the blade shell and bear the bending load on the blade. Baffles are provided at both ends of the web, which are used to bond with the inner wall surfaces of the upper and lower shells of the blades with glue. Since the blade shell gradually becomes thinner from the root to the head, and the blade shell is a curved surface, the angle between the baffles at both ends of the web and the web should also be adjusted with the change of the curved surface of the inner wall surface of the shell, so as to ensure better bonding between the baffle and the inner wall surface of the upper and lower shells. Therefore, the angle adjustment between the baffle and the web is achieved by adjusting the angle between the baffle mold and the web through a specific tooling. The angle between the baffle and the web after demoulding is the same as the angle between the baffle mold and the web.

The rib adjustment device includes a fixed plate and an adjustment plate that can be lifted and lowered relative to the fixed plate. The adjustment plate is fixedly connected with at least three adjustment rods, each of which is fixedly connected to the back of the mold rib. Each adjustment rod can move inward and outward to adjust the inner and outer positions of the mold ribs, and adjust the angle of the mold ribs relative to the large mold surface by controlling the extension and contraction of each adjustment rod. The method of the present invention includes: setting the height of the blade web and the angle of the ribs on both sides; adjusting the angle of each mold rib to be consistent with the angle of the rib on the same side, and adjusting the inner and outer positions of each mold rib to be consistent with the height of the blade web, and pouring to obtain the web.

[0023] Among them, the fixing component 5 includes a connecting plate 501 connected to the ends on the same side of the slide rail 1 and the connecting plate 2, a U-shaped clamp 502 is arranged on the side of one end of the connecting plate 501, a rotating shaft 503 is arranged at the end of the U-shaped clamp 502, the rotating shaft 503 is rotatably arranged on the connecting plate 501, one end of the rotating shaft 503 passes through the connecting plate 501 and is rotatably connected to a pull ring 504, a nut 505 is arranged on the side surface of the U-shaped clamp 502, and a fastening bolt 506 whose end passes through the side wall of the U-shaped clamp 502 is rotatably connected inside the nut 505.

[0024] One end of the guide rod 306 is provided with an external thread, and one end of the adjustment member 305 is provided with an internal thread screw-on hole matched with the guide rod 306 .

[0025] The adjusting member 305 includes an adjusting shaft 3051 , one end of which is connected to a knob 3052 , and a surface of the knob 3052 is provided with an anti-slip protrusion.

[0026] The adjusting ruler 308 is provided with an arc-shaped through hole 3081 , and scales 3082 are provided on both sides of the arc-shaped through hole 3081 .

[0027] When in use, first clamp the U-shaped clip 502 of the fixing assembly 5 at the two ends of the web in the horizontal direction, and then twist the fastening bolt 506, so that the fastening bolt 506 rotates in the nut 505 and moves into the U-shaped clip 502, and then the end of the fastening bolt 506 will press the surface of the web, so that the entire tooling is fixed on the web, and then move the angle adjustment assembly 3 on the slide rail 1 to the middle of the slide rail 1, and turn the knob 3052 according to the design angle between the web section and the retaining edge, thereby driving the adjustment shaft 3051 connected to the knob 3052 to rotate, and the adjustment shaft 3051 rotates so that the thread in the threaded connection hole at one end of the adjustment shaft 3051 rotates on the external thread at the end of the guide rod 306.
