[0020] A method for using a wind turbine blade static load deflection tilt testing device includes the following steps:

[0021] S1: Clamping operation:

[0022] The wind turbine blade is transported to the clamping assembly. The two first pressure rods and the two second pressure rods clamp the left end of the wind turbine blade respectively. The two second hydraulic cylinders are activated until the clamp holds the right end of the wind turbine blade and then stops. The two first hydraulic cylinders are activated to fix the positions of the two first hydraulic cylinders and the clamp, thus completing the clamping of the wind turbine blade.

[0023] S2: Calibration operation:

[0024] Start the slide rail motor, and the two sliding blocks move to the right side, aligning the laser collimator with the calibration hole. Start the moving cylinder, and the scissor fork drives the lower platform to descend, activating the laser collimator. The laser is reflected by the calibration plate to the laser receiver, and the receiver receives the signal and transmits it to the controller, completing the calibration operation.

[0025] S3: Adjust the detection operation:

[0026] If calibration is required, start the rotating cylinder. The rotating cylinder drives the rotating connecting piece to rotate around the connecting rod support frame as the origin, which in turn drives the drive rod to rotate, causing the laser collimator to rotate around the laser support frame as the origin, thus adjusting the angle position of the laser collimator.

[0027] Start the slide rail motor, and the two sliding blocks move to the left to align the laser collimator with the position of each detection hole. Start the moving cylinder, and the scissor fork drives the lower platform to descend. Start the laser collimator, and the laser is reflected through each detection hole to the laser receiver. The receiver receives the signal and transmits it to the controller to complete the detection operation.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) By setting the moving component and the detection component, the technical effect that can be achieved is that the left and right ends of the sliding track are fixedly connected to the two columns respectively, and an auxiliary rod is fixedly set between the two columns. The auxiliary rod is located below the sliding track. Two sliding blocks are slidably set on the sliding track. The two sliding blocks are slidably connected to the auxiliary rod. A sliding track motor is fixedly set on the sliding track. The lower ends of the two sliding blocks are fixedly connected to the upper end of the upper platform. The upper right end of the scissor fork is rotatably connected to the upper platform. The lower right end of the scissor fork is rotatably connected to the lower platform. An upper sliding groove is opened on the upper platform. The upper left end of the scissor fork is slidably connected in the upper sliding groove.

[0030] If calibration is required, start the rotating cylinder. The rotating cylinder drives the rotating connecting part to rotate around the connecting rod support frame as the origin, which in turn drives the drive rod to rotate, causing the laser collimator to rotate around the laser support frame as the origin. Adjust the angle and position of the laser collimator. The moving component and the detection component can automatically adjust the laser collimator to a suitable angle and position and move the laser collimator without manual adjustment, making it more automated and convenient, and making the adjustment more accurate.

[0031] (2) By setting up receiving components and detection components, the technical effect that can be achieved is that the front and rear ends of the calibration plate are fixedly connected to the upper ends of the two side support plates respectively, the right end of the calibration plate is fixedly connected to the left side of the right column, the lower end of the calibration plate is fixedly provided with a bottom plate, the right side of the bottom plate is fixedly connected to the left side of the right column, the lower end of the laser receiver is fixedly provided with multiple receiving components, the laser receiver is provided with multiple detection holes and one calibration hole, the multiple detection holes are located to the left of the calibration hole, the laser receiver is fixedly provided with a controller inside, and the calibration hole is located above the calibration plate.

[0032] Start the slide rail motor, and the two sliding blocks move to the right side, aligning the laser collimator with the calibration hole. Start the moving cylinder, and the scissor fork lowers the platform, activating the laser collimator. The laser is reflected by the calibration plate to the laser receiver, which receives the signal and transmits it to the controller, completing the calibration operation. The receiving and detection components can perform automatic calibration tests and static load deflection tilt tests on the detection components. The laser receiver receives the laser signal and transmits it to the controller. The fixed calibration and detection holes determine the angle of the offset and calculate the required static load deflection tilt data.

[0033] (3) By setting the clamping assembly, the technical effect that can be achieved is that the lower ends of the two first support columns are fixedly connected to the ground rail, two first pressure rods are detachably set between the two first support columns, the lower ends of the two second support columns are fixedly connected to the ground rail, two second pressure rods are detachably set between the two second support columns, the lower ends of the two third support columns are fixedly connected to the ground rail, a first frame connecting rod is detachably set between the two third support columns, two second oil cylinders are fixedly set at the lower end of the first frame connecting rod, and the lower ends of the two fourth support columns are fixedly connected to the ground rail.

[0034] The wind turbine blade is transported to the clamping assembly. Two first pressure rods and two second pressure rods clamp the left end of the wind turbine blade. The two second hydraulic cylinders are activated until the clamp holds the right end of the wind turbine blade and then stops. The two first hydraulic cylinders are then activated to fix the positions of the two first hydraulic cylinders and the clamp, thus completing the clamping of the wind turbine blade. The clamping assembly can clamp wind turbine blades of various types and sizes without the need for parts replacement, making it more versatile. It can achieve fast and efficient clamping operations, reducing manual intervention and operation time. By evenly distributing the clamping force, it reduces the risk of damage to the wind turbine blade. Attached Figure Description
