Description

Technical Field

Due to the roughness of the blade surface, other employees vibrating the blade when repairing it, and people accidentally touching the scanner when passing by, all of these may cause the scanner to fall from the surface of the wind turbine blade. Scanner falling accidents often occur, frequently causing damage to the phased array scanner, and occasionally causing personnel safety accidents.

[0004] In order to solve the above problems, the trailing edge suspension tooling disclosed in the utility model patent with publication number CN219327597U can prevent the wind turbine blade phased array scanner from falling, better protect the instruments and equipment, reduce the damage to the phased array scanner, and effectively ensure the safety of personnel.

[0005] However, when the above-mentioned suspension tooling is actually used, when inspecting wind turbine blades of different sizes, when the wind turbine blade phased array scanner is inspecting at different heights and different positions, the suspension mechanism may not follow in time when moving, causing the phased array scanner to fall.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The embodiment of the present application discloses a wind turbine blade trailing edge suspension tool, specifically comprising a movable ring 1, wherein both sides of the movable ring 1 are fixedly connected with a rotating suspension mechanism;

[0041] The rotating suspension mechanism includes two arc-shaped clamping rings 2, three sleeves 3 are fixedly connected inside the two arc-shaped clamping rings 2, rolling balls 4 are movably connected inside the multiple sleeves 3, multiple movable seats 5 are fixedly connected to the outside of the movable ring 1, support arms 6 are movably connected to the outside of the multiple movable seats 5, guide wheels 7 are movably connected inside the multiple support arms 6, support plates 8 are fixedly connected to one side of the multiple movable seats 5, two springs 9 are fixedly connected to the other side of the multiple support plates 8, two fixed plates 10 are fixedly connected to the outside of the multiple support plates 8, and two hanging rings 11 are fixedly connected to the outside of the two fixed plates 10. Through the multiple rolling balls 4 and the multiple guide wheels 7, the movable ring 1 can be horizontally moved and rotated on the outside of the blade to maintain stability and improve the use efficiency of the movable ring 1.

[0042] Reference Figure 5 As shown, specifically, the movable ring 1 is fixedly connected with fixed blocks 12 on the upper and lower sides, and the two fixed blocks 12 are fixedly connected with telescopic racks 13 on one side, and a plurality of card slots 14 are arranged on the top of the telescopic racks 13, and the outer sides of the two telescopic racks 13 are movably connected with jack blocks 15, and the insides of the two jack blocks 15 are movably connected with screws 16, and the bottoms of the two screws 16 are fixedly connected with fixed card blocks 17, which can fix the trailing edges of blades of different sizes, thereby improving the applicability of the movable ring 1.

[0043] Reference Figure 4 As shown, specifically, three sleeves 3 are fixedly connected inside the two arc-shaped clamping rings 2, and rolling balls 4 are movably connected inside the multiple sleeves 3, so that the movable ring 1 can maintain stable rotation on the outer side of the blade.

[0044] The working principle of the utility model is as follows: when in use, first open the two jack blocks 15 on the upper and lower sides of the movable ring 1, then pull out the two telescopic racks 13 from the inside of the jack blocks 15, wrap the separated movable ring 1 with the outer side of the trailing edge of the wind turbine blade, and then reinsert the two telescopic racks 13 into the corresponding jack blocks 15. After that, when the separated movable ring 1 is fitted with the trailing edge of the wind turbine blade, the two jack blocks 15 are screwed downward again to plug the fixed card blocks 17 at the bottom of the two jack blocks 15 with the corresponding card slots 14 at the top of the telescopic racks 13, so that the separated movable ring 1 is fitted with the trailing edge of the wind turbine blade. Maintain a relatively close fit. When the phased array scanner inspects the outside of the wind turbine blade, it moves along the trailing edge of the blade. The second motor 23 inside the second fixed cylinder 22 on the other side of the movable ring 1 drives the second roller 24 to push the outside of the blade. Under the auxiliary guidance of multiple guide wheels 7 on both sides of the movable ring 1, the movable ring 1 maintains stable movement on the outside of the blade. At the same time, the first motor 20 inside the first fixed cylinder 19 drives the first roller 21 to allow the movable ring 1 to rotate on the outside of the blade, so that the movable ring 1 can better cooperate with the movement of the phased array scanner, thereby improving the safety of using the phased array scanner.
