Description

Technical Field

[0001] This utility model relates to a metal mesh laying device for wind turbine blades, which belongs to the technical field of lightning protection network laying. Background Technology

[0002] Metal mesh, due to its advantages such as good flexibility, high conductivity, and good conformability, is widely used in wind turbine blades for lightning protection. During the wind turbine blade manufacturing process, it is laid on the surface of the mold. Currently, the laying method is all manual. Operators slowly walk on the mold to unroll and unfold the mesh. The mold surface is curved, and the metal mesh roll is quite heavy, making it difficult for personnel to operate on it, resulting in low laying efficiency and difficulty in guaranteeing the laying effect. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a metal mesh laying device that can be used with molds of different leaf shapes, is simple to operate, and has high laying efficiency.

[0004] The technical solution adopted by this utility model is: a metal mesh laying device for wind turbine blades, which includes a metal mesh and a drum. The device includes a support and fixing component, a telescopic component and a moving and lifting component. In the support and fixing component, the drum supports the metal mesh and the drum. Bearing heads are provided at both ends of the drum. The bearing heads are set on the drum through set screws.

[0005] The telescopic component uses a telescopic shaft, one end of which is connected to a reel, and the other end of which is fixed to the movable lifting component.

[0006] The top of the lifting platform in the mobile lifting assembly is provided with a retaining ring and screws, and the end of the telescopic shaft is placed in the retaining ring and fixed with screws;

[0007] The movable lifting assembly is located on the flange side of the mold, and the support and fixing assembly is located above the wind turbine blade mold.

[0008] The telescopic shaft includes a telescopic end and a fixed end.

[0009] The telescopic end of the telescopic shaft is threaded to the end of the reel.

[0010] The fixed end of the telescopic shaft is fixed to the movable lifting assembly.

[0011] A level is installed at the top of the fixed end.

[0012] The bottom of the lifting platform is equipped with movable rollers.

[0013] The device uses two sets of telescopic components and a movable lifting component, which are respectively set on both sides of the supporting and fixed component.

[0014] The metal mesh has a roll inside, and the metal mesh is rolled up and packaged on the roll.

[0015] A bearing head is installed on each of the left and right sides of the reel, and the inner diameter of the bearing head matches the outer diameter of the reel. A set screw is installed on each bearing head to secure it to the reel.

[0016] The reel is provided with internal threads at both ends.

[0017] The telescopic shaft is telescopic, and one end of the telescopic shaft is provided with an external thread. The external thread of the telescopic shaft and the internal thread of the reel are matched with each other.

[0018] The lifting platform is equipped with movable rollers that can roll, and a retaining ring is provided on the lifting platform to hold one end of the telescopic shaft and fix it with screws.

[0019] The level is placed at the top of the telescopic shaft.

[0020] The lifting platform is placed on the edge of the mold flange.

[0021] The method of using the metal mesh laying device is as follows: Place the rolled metal mesh in the middle of the roll, adjust the bearing top to lock the metal mesh roll, and fix the bearing top to the roll with the set screw; install the telescopic shaft on both sides of the roll, insert one end of the telescopic shaft into the lifting platform retaining ring and fix it with screws, place the lifting platform on the edge of the mold flange, and adjust the height of the lifting platform by observing the level to ensure that the laying roll is kept at a uniform height and in a horizontal state. Pushing the lifting platform can release the metal mesh rolled on the wind turbine blade mold.

[0022] Because the front and rear flange edges of the wind turbine blade mold are at different heights, and the height and width of the mold vary along its length, a lifting platform and a telescopic shaft are required. Changes in mold width can be accommodated by adjusting the telescopic shaft, and changes in mold height can be accommodated by adjusting the lifting platform.

[0023] The present invention has the following advantages: the device includes a support and fixing component, a telescopic component, and a moving and lifting component. The support and fixing component is used to support the drum and the metal mesh. The telescopic component uses the extension and shortening of the telescopic shaft to adjust and adapt to changes in the laying width direction. The moving and lifting component uses a lifting platform, which adapts to changes in the mold height direction by lifting and lowering the platform. At the same time, the bottom of the lifting platform is equipped with moving rollers, which can drive the laying device to move along the mold flange edge to lay the metal mesh.

[0024] This device replaces manual labor in laying the mesh on the mold, saving manpower and ensuring that the roller remains horizontal during laying, guaranteeing the laying effect and improving efficiency. It is also not limited by blade shape and can be used with any type of mold, adapting to different shapes by adjusting the telescopic shaft and lifting platform. Attached Figure Description

Bearing heads 4 are installed at both ends of the drum 2, and the bearing heads 4 are mounted on the roller 3 via set screws 5. The telescopic assembly uses a telescopic shaft 6, one end of which is connected to the roller 3, and the other end is fixed to the movable lifting assembly. The telescopic shaft 6 includes a telescopic end 6a and a fixed end 6b. The telescopic end 6a of the telescopic shaft 6 is threadedly connected to the end of the roller 3. The fixed end 6b of the telescopic shaft 6 is fixed to the movable lifting assembly. A level 10 is installed at the top of the fixed end 6b.

The mobile lifting assembly is set on the mold flange edge 12, and the support and fixing assembly is set above the wind turbine blade mold 11.

[0033] Specifically, Fig. 1 This is a schematic diagram of metal mesh packaging. Inside the metal mesh 1 is a roll 2, and the metal mesh 1 is rolled up and packaged on the roll 2.

[0034] Fig. 2Exploded view of the metal mesh laying device. A bearing head 4 is installed on each of the left and right sides of the reel 3. The inner diameter of the bearing head 4 matches the outer diameter of the reel 3. A set screw 5 is installed on the bearing head 4 to secure it to the reel 3. Internal threads are provided at both ends of the reel 3. The telescopic shaft 6 is extendable in length. One end of the telescopic shaft 6 has an external thread, which matches the internal thread of the reel.

[0035] The lifting platform 7 is equipped with wheels for rolling. A retaining ring 8 is also installed on the lifting platform 7, which can hold one end of the telescopic shaft 6 and is secured with screws 9. A level 10 is placed on the top of the telescopic shaft 6. The lifting platform 7 is placed on the mold flange edge 12.

[0036] When using the above technical solution, the method of using the metal mesh laying device is as follows: place the rolled metal mesh 1 in the middle of the roller 3, adjust the bearing top 4 to lock the metal mesh roll 2, and fix the bearing top 4 on the roller 3 by the top screw 5; install the telescopic shaft 6 on both sides of the roller 3, insert one end of the telescopic shaft 6 into the locking ring 8 of the lifting platform 7 and fix it by the screw 9, place the lifting platform 7 on the mold flange edge 12, and adjust the height of the lifting platform 7 by observing the level 10 to ensure that the laying roller 3 is kept at a uniform height and in a horizontal state.
