Technical Field

[0001] This utility model belongs to the field of wind turbine nacelle processing technology, specifically relating to a jig structure for batch processing of wind turbine nacelles. Background Technology

[0002] In recent years, wind power generation has developed rapidly worldwide as a clean energy source. Continuous design optimization has led to the maturity of the technology for applying composite materials to wind turbine nacelle covers. During the processing of wind turbine nacelle covers, clamps are needed to hold and fix them to facilitate subsequent processing.

[0003] Current fixtures cannot simultaneously clamp and fix wind turbine nacelle covers in batches. At the same time, they cannot position the wind turbine nacelle covers during the clamping process, resulting in low clamping accuracy and affecting the accuracy of subsequent processing. To address this, we propose a fixture structure for batch processing of wind turbine nacelles. Utility Model Content

[0011] Preferably, a connecting sleeve is provided at the bottom of the nacelle body, the connecting sleeve being used to connect with the tower of the wind turbine.

[0012] Preferably, the bottom plate on one side of the gripper also has positioning holes, which correspond one-to-one with the connecting sleeves, enabling the connecting sleeves to be positioned.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a jig structure for batch processing of wind turbine nacelles, including a base plate 1, a support rod 5 on the base plate 1, a top plate 3 on the top of the support rod 5, and multiple sets of clamping components 2 for synchronously fixing multiple sets of nacelle bodies 4 are equidistantly arranged on the base plate 1. This application can increase or decrease the clamping components 2 according to the actual processing situation.

[0025] The clamping assembly 2 includes a hydraulic cylinder 21, which is rotatably mounted in a first ear seat 28 via a rotating shaft. The first ear seat 28 is located on one side of the base plate 1. One end of the piston rod of the hydraulic cylinder 21 is provided with a clamping head that automatically rotates with the extension and retraction of the piston rod. The clamping head is used to clamp and fix the inner wall of the cabin body 4.

[0026] Furthermore, the clamping head includes a connecting frame 23, which is rotatably connected to the end of the piston rod. The other end of the connecting frame 23 is provided with a clamping claw 24. Through the extension and retraction of the piston rod, the clamping claw 24 can be rotated to complete the clamping and fixing of the cabin body 4.

[0027] Furthermore, a connecting ring 22 is provided at one end of the piston rod. The connecting ring 22 is rotatably connected to the connecting frame 23 through a rotating shaft, which improves the stability of the connecting frame 23 when it rotates.

[0028] Furthermore, ear plates 26 are provided on both sides of the bottom of the gripper 24. The ear plates 26 are rotatably connected to the second ear seat 27 via a rotating shaft. The second ear seat 27 is located on one side of the base plate 1, which improves the stability of the gripper 24 when it rotates.

[0029] Furthermore, an arc-shaped claw 25 is also provided on one side of the gripper 24. The arc-shaped claw 25 fits against the inner wall of the cabin body 4, which can fit against the inner wall of the cabin and improve the stability of the cabin fixation.

[0030] Furthermore, a connecting sleeve 7 is provided at the bottom of the nacelle body 4. The connecting sleeve 7 is used to connect with the tower of the wind turbine. The bottom plate 1 on one side of the gripper 24 also has positioning holes 6. The positioning holes 6 correspond one-to-one with the connecting sleeve 7, which can position the connecting sleeve 7.

[0031] The multiple sets of hydraulic cylinders 21 in this application are all connected to the same servo hydraulic control system, which can synchronously control the extension and retraction of the multiple sets of hydraulic cylinders 21.

[0032] Working principle and usage process of this utility model:

[0033] First, the connecting sleeves 7 on multiple sets of cabin bodies 4 are placed sequentially into the positioning holes 6 on the base plate 1. Then, the piston rod of the hydraulic cylinder 21 is extended synchronously through the servo hydraulic control system. The bottom of the hydraulic cylinder 21 rotates in the first ear seat 28. At the same time, the extension of the piston rod drives the connecting frame 23 to rotate. The connecting frame 23 drives the ear plate 26 to rotate in the second ear seat 27. The connecting frame 23 also drives the gripper 24 to rotate. The arc-shaped claw 25 on the gripper 24 fits against the inner wall of the cabin body 4, thereby synchronously and batch fixing multiple sets of cabin bodies 4 and batch processing of the cabin bodies 4.

[0034] After the engine compartment body 4 is processed, the hydraulic cylinder 21 is operated to retract the piston rod of the hydraulic cylinder 21. During the retraction of the piston rod, the connecting frame 23 drives the gripper 24 to reset and rotate, and the arc-shaped chuck 25 on the gripper 24 separates from the inner wall of the engine compartment body 4, releasing multiple sets of engine compartment bodies 4 simultaneously, which facilitates the unloading operation of the engine compartment body 4.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
