[0025] In this embodiment, Figure 1-2 A wind turbine blade conveying and fixing platform with anti-seismic function is provided. The present invention includes two horizontal plates 1 distributed upper and lower, an anti-seismic mechanism 2 is provided between the two horizontal plates 1, a plurality of laterally distributed frames 3 are provided above the upper horizontal plate 1, and a fixing mechanism 5 is provided on the inner side wall of the frame 3. Connecting seats 6 are provided on both sides of the top of the upper horizontal plate 1, and a circular shaft 7 passing through the lower ends of the plurality of frames 3 is provided between the two connecting seats 6. A fixing mechanism is provided on the top of the upper horizontal plate 1 for positioning the frame 3.

[0026] In this embodiment, the device is installed on the transport equipment, and the blades are passed through multiple frames 3 and the positions of the frames 3 are adjusted according to the lengths of the blades. Then, the frames 3 can be positioned by the fixing mechanism to prevent them from moving, and the blades are placed on the inner bottom wall of the frames 3. At this time, the blades are clamped and fixed by the fixing mechanism 5, which can be quickly fixed. During transportation, the anti-vibration mechanism can be used to reduce shock to avoid excessive vibration of the blades and reduce friction and collision between the blades and the contact objects.

[0027] Preferably, as another embodiment of the present invention, the anti-seismic mechanism 2 includes a damper 21, a spring 22, a slider 23, a connecting block 24, a slide rail 25 and a buffer rod 26.

A buffer rod 26 is hinged between the slider 23 and the upper horizontal plate 1, and a damper 21 is provided between the two horizontal plates 1.

[0028] In this embodiment, the vibration generated by the blades during transportation will act on the upper horizontal plate 1. When the upper horizontal plate 1 is subjected to external vibration or impact, the lower end of the buffer rod 26 moves, and drives the slider 23 to move on the slide rail 25, so that the slider 23 squeezes or stretches the spring 22. The spring 22 absorbs and stores energy through deformation, thereby reducing the amplitude and speed of the vibration, playing a role in buffering and shock absorption. The damper 21 provides damping force to suppress the free vibration of the spring 22, and converts the stored energy into heat energy for consumption, so that the vibration of the system gradually weakens and transitions smoothly. The damper can effectively control the vibration process of the structure, avoid destruction or damage caused by vibration, improve the stability and safety of the system, and thus achieve the effect of shock absorption.

[0029] Preferably, as another embodiment of the present invention, the fixing mechanism 5 includes a motor 51, a bracket 52, a threaded rod 53, an internally threaded barrel 54, a limiting rod 55 and an arc block 56.

[0030] In this embodiment, due to the elasticity and softness of the rubber itself, it has good shock absorption and buffering capabilities. At the same time, the rubber has soft characteristics, which prevents the frame 3 and the arc block 56 from scraping the surface of the blade, and can protect the contacted blades. The motor 51 can drive the threaded rod 53 to rotate, and the threaded rod 53 will be connected to the internal threaded barrel 54 in a transmission manner, so that the internal threaded barrel 54 moves vertically downward, and the arc block 56 connected to the internal threaded barrel 54 moves downward under the limit of the limit rod 55 to clamp the blades in the frame 3.

[0031] Preferably, as another embodiment of the present invention, the frame fixing mechanism includes a positioning block 81, a fixed block 82, a movable plate 83, a bidirectional screw 84, an extension port 85, a positioning slot 86, a through hole 87 and a driving mechanism 9. A plurality of through holes 87 are equidistantly provided on the front of the upper horizontal plate 1. The front and rear sides of the inner wall of the through hole 87 are provided with a fixed block 82. The front of the front fixed block 82 is rotatably connected to a bidirectional screw 84 that passes through the front of the front fixed block 82. The front and rear sides of the inner top wall of the through hole 87 are provided with an extension port 85. The thread rotation directions of the two ends of the bidirectional screw 84 are opposite to each other. The two ends of the bidirectional screw 84 are Both are transmission connected with a movable plate 83 extending to the top of the protruding port 85 on the same side.

A driving mechanism 9 is provided between the bidirectional screw rod 84 and the upper horizontal plate 1. The driving mechanism 9 includes a second motor 91, a worm gear 92 and a worm 93. The front end fixing sleeve of the bidirectional screw rod 84 is provided with a worm gear 92. The front side of the upper horizontal plate 1 is provided with a second motor 91. The output shaft of the second motor 91 is coaxially connected with a worm gear 93 which is transmission-connected to the worm gear 92. The other end of the worm gear 93 is rotationally connected to the front side of the upper horizontal plate 1.

[0032] In this embodiment, the motor 2 91 outputs torque, which can drive the worm 93 to rotate. During this process, the worm 93 will engage with the worm wheel 92 on the bidirectional lead screw 84 to drive the bidirectional lead screw 84 to rotate, so that the movable plates 83 on both sides move relative to each other, and the positioning blocks 81 thereon can move accordingly. When the positioning block 81 corresponds to the positioning groove 86 on the frame 3, the positioning block 81 can enter the positioning groove 86 to complete the positioning operation of the frame 3, so that the frame 3 is fixed.

[0034] In this embodiment, the housing 10 can isolate the running components from the outside world to avoid injuries caused by accidental collisions and damage to the components. At the same time, it can prevent impurities from entering the device and causing damage to the components, thereby extending the service life of the product.

[0035] Preferably, as another embodiment of the present invention, both ends of the top of the lower horizontal plate 1 are provided with positioning shafts 11 that penetrate to the top of the upper horizontal plate 1 .

[0036] In this embodiment, the positioning shaft 11 can limit the upper horizontal plate 1 to prevent the upper horizontal plate 1 from shaking horizontally, so that the upper horizontal plate 1 can only move vertically.

[0037] Preferably, as another embodiment of the present invention, a T-shaped slot 121 is provided on the top of the upper horizontal plate 1 , and a T-shaped block 122 whose upper end is connected to the bottom of the frame 3 is slidably connected inside the T-shaped slot 121 .

[0038] In this embodiment, the T-shaped block 122 connected to the frame 3 can slide in the T-shaped slot 121. When the frame 3 is positioned and stationary, the T-shaped block 122 can support the frame 3 to prevent the weight of the frame 3 from acting on the circular shaft 7.

[0039] Working principle: Fix the lower horizontal plate 1 on the transport equipment, then pass the blades through multiple frames 3, and adjust the position of the frame 3 according to the length of the blades. Then, the motor 1 51 can drive the threaded rod 53 to rotate, and the threaded rod 53 will be connected to the internal threaded cylinder 54 for transmission, so that the internal threaded cylinder 54 moves vertically downward, and the arc block 56 connected to the internal threaded cylinder 54 moves downward under the limit of the limit rod 55 to clamp the blades in the frame 3. At the same time, the motor 2 91 drives the worm 93 to rotate, and the worm 93 will engage with the worm gear 92 on the bidirectional lead screw 84 to drive the bidirectional lead screw 84 to rotate, so that the movable plates 83 on both sides move relative to each other, and the positioning blocks 81 thereon can move accordingly. When the positioning block 81 corresponds to the positioning groove 86 on the frame 3, the positioning block 81 can enter the positioning groove 86 to complete The positioning operation of the frame 3 keeps the frame 3 stationary. During transportation, the vibration on the blades will act on the upper horizontal plate 1. When the upper horizontal plate 1 is subjected to external vibration or impact, the lower end of the buffer rod 26 moves, and drives the slider 23 to move on the slide rail 25, so that the slider 23 squeezes or stretches the spring 22. The spring 22 absorbs and stores energy through deformation, thereby reducing the amplitude and speed of vibration, playing a role in buffering and shock absorption. The damper 21 provides damping force to suppress the free vibration of the spring 22, and converts the stored energy into heat energy for consumption, so that the system vibration gradually weakens and transitions smoothly. The damper can effectively control the vibration process of the structure, avoid destruction or damage caused by vibration, improve the stability and safety of the system, and thus achieve the effect of shock absorption.
