Description

Technical Field

[0001] This utility model relates to the technical field of workpiece transfer devices, and in particular to a wind turbine blade web transfer device. Background Technology

[0002] The blade profile of wind turbine blades is developing at an increasingly rapid pace, and the length of the web and the angle of the side webs are becoming more and more diverse. Existing web transfer and lifting fixtures occupy a large area, lack rotating pin devices, take a long time to transfer, and have poor performance. Occasionally, vacuum failure will occur, causing significant delays in production and posing significant safety hazards.

[0003] In the prior art, patent (CN113895881B) proposes a wind turbine blade web transfer device, including at least two movable supports for supporting the wind turbine blade web. An omnidirectional trolley is located below the movable supports, with an automatic lifting mechanism at the top of the omnidirectional trolley for lifting the movable supports, and omnidirectional wheels at the bottom of the omnidirectional trolley. This application provides a more efficient, accurate, and intelligent transfer device for wind turbine blade web transfer. For manufacturers, using an intelligent transfer device that is omnidirectionally movable, autonomously positioned and navigates with obstacle avoidance, and remotely controlled can significantly improve transfer efficiency, reduce labor costs, lower the risk of workplace injuries, increase labor productivity, and enhance economic benefits.

[0004] However, in the aforementioned prior art, the movable support is limited to automatically adjusting the deflection angle to adapt to the blade web, resulting in poor clamping and stability of the blade web, and it is not suitable for transporting webs of various specifications. Summary of the Invention

The support rods 115 are fixedly connected, and the lower end of each support rod 115 is fixedly connected to the swing plate 114. The swing plate 114 is rotatably connected to the bracket 104. Each sleeve 119 is fixedly connected to the vehicle body 117. Each universal wheel 118 is fixedly connected to the vehicle body 117. The vehicle body 117 is fixedly connected to two cylinders 103. The dual-axis motor 112 in the adjustment assembly 107 drives two threaded rods 113 to drive the two side plates 110 in the swing assembly 108, thereby adjusting the clamping and stabilizing effect of the two side plates 110 and the corresponding uprights 111 on the web plate. Accompanied by the height adjustment of the two cylinders 103, the practicality is better. This design is convenient to operate and use, and solves the problem that the moving bracket is limited to automatically deflecting the angle to adapt to the blade web plate, has poor clamping and stability of the blade web plate, and is not suitable for transporting web plates of various specifications.

The pull plate 109 gradually moves from the swing disk 114 under the threaded drive of the corresponding threaded rod 113, but will not disengage from the swing disk 114, thus playing the role of maximizing movement limit.

[0023] Secondly, each of the uprights 111 is located above the side plate 110, the side plate 110 is located on one side of the drawer plate 109, the drawer plate 109 is located on one side of the rocker assembly 108, the periphery of the two threaded rods 113 is located on the inner side of the corresponding side plate 110, and the dual-axis motor 112 is located on the inner side of the rocker assembly 108. When the bracket 104 moves under the drive of the two cylinders 103, each of the sliding rods 105 below the bracket 104 slides up and down on the inner side of the corresponding sleeve 119 to limit the movement trajectory of the bracket 104. Similarly, each of the universal wheels 118 is provided with a shock-absorbing spring on the inner side above to reduce the pressure on the vehicle body 117 after the web plate is placed on the placement plate 116.

The inner side of each side plate 110 has a thread that is compatible with the corresponding threaded rod 113. The two adjust the clamping tension of the web plate by rotating the thread, and can adapt to the front and rear end deflection of the web plate. The placement plate 116 and the swing plate 114 are provided above the bracket 104, so the swing plate 114 can deflect around the rotating shaft to adapt to the changes of the web plate. Then, the two cylinders 103 raise or lower the height of the bracket 104 according to the transportation situation, so as to pass through different scenarios.

[0025] In this embodiment, limit frames are provided on both sides of the sway plate 114. The pull plate 109 gradually moves from the sway plate 114 under the threaded drive of the corresponding threaded rod 113, but will not disengage from the sway plate 114, thus playing a role in maximizing movement limitation. When the bracket 104 moves under the drive of the two cylinders 103, each of the sliding rods 105 below the bracket 104 slides up and down on the inner side of the corresponding sleeve 119, limiting the movement trajectory of the bracket 104. Similarly, a shock-absorbing spring is provided on the inner side above each universal wheel 118 to reduce the pressure on the vehicle body 117 after the web plate is placed on the placement plate 116, thus limiting the movement of the wind turbine blade. When the web plate is transferred, at least two or more of these devices are required. Under the action of the tower crane, the web plate is placed above the placement plate 116, and the dual-shaft motor 112 is started. The inner side of each side plate 110 has threads that are compatible with the corresponding threaded rod 113. The two adjust the clamping tension of the web plate by rotating the threads, and can adapt to the front and rear end deflection of the web plate, the placement plate 116 and the swing plate 114.
