Other devices, although possessing measurement capabilities, lack sufficient accuracy and flexibility, failing to meet the accurate measurement requirements for wind turbine pitch bolts of different diameters. Furthermore, existing devices struggle to guarantee bolt stability during inspection, and the accuracy of the results can be affected by shaking or tilting.

In the above bolt fixing structure, springs and clamps are used to fix the detection bolts. The shape of the clamps is fixed, and the fixing effect is not good.

[0027] 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.

[0028] Please see Figure 1-4 This utility model provides a wind turbine pitch bolt fracture detection device, comprising:

[0029] Mounting housing 1, with a conveyor belt 2 inside the mounting housing 1. Multiple evenly distributed detection bolts 5 are provided at the upper end of the conveyor belt 2, and a support assembly is provided on the conveyor belt 2 to support the detection bolts 5.

[0030] A rotating assembly 6 for driving the detection bolt 5 to rotate is provided on the side wall of the mounting housing 1.

[0031] A measuring component 8 for measuring the diameter of the inspection bolt 5 is provided on the side wall of the mounting housing 1.

[0032] Mounting housing 1 serves as the main structure, providing a platform for the installation and support of various components. Inside mounting housing 1 is a conveyor belt 2, a continuously operating conveying mechanism driven by a motor to achieve cyclic rotation. At the upper end of conveyor belt 2, multiple evenly distributed inspection bolts 5 are placed. These inspection bolts 5 are the objects to be inspected, passing through the inspection stage sequentially as conveyor belt 2 moves. To ensure the stability of the inspection bolts 5 during transportation, support components are also provided on conveyor belt 2 to support them. These components prevent the inspection bolts 5 from shaking or tipping over during transportation, ensuring the accuracy of the inspection.

[0033] The rotating assembly 6 includes a first electric push rod 61, a moving block 62, a second electric push rod 64, a lifting frame 65, a rotary motor 67, a rotating frame 68, and a magnetic disk 69.

[0034] The mounting housing 1 has a first electric actuator 61 fixedly connected to its side wall. A moving block 62 is fixedly connected to the output end of the first electric actuator 61. Two symmetrically distributed first guide rods 63 are fixedly connected to the side wall of the moving block 62. The two first guide rods 63 are slidably connected to the mounting housing 1. A second electric actuator 64 is provided inside the moving block 62. A lifting frame 65 is fixedly connected to the output end of the second electric actuator 64. A second guide rod 66 is fixedly connected to the lower end of the lifting frame 65. The second guide rod 66 is slidably connected to the moving block 62. A rotary motor 67 is provided at the upper end of the lifting frame 65. The output shaft of the rotary motor 67 is connected to a rotating frame 68 through a gearbox. The rotating frame 68 is rotatably connected to the lifting frame 65. A magnetic disk 69 is fixedly connected to the side wall of the rotating frame 68. The magnetic disk 69 is rotatably connected to the lifting frame 65.

[0035] When the first electric actuator 61 is energized, its output end extends or retracts, thereby driving the moving block 62 to move horizontally. To ensure the stability of the moving block 62, two symmetrically distributed first guide rods 63 are fixedly connected to the side wall of the moving block 62. These two first guide rods 63 are slidably connected to the mounting shell 1, restricting the direction of movement of the moving block 62 and preventing it from deviating during movement. A second electric actuator 64 is provided inside the moving block 62. A lifting frame 65 is fixedly connected to the output end of the second electric actuator 64. When the second electric actuator 64 is energized, its output end drives the lifting frame 65 to move vertically. To ensure the stability of the lifting frame 65, a fixed... A second guide rod 66 is connected to the lifting frame 65, which is slidably connected to the moving block 62. The sliding cooperation between the guide rod and the moving block 62 restricts the movement direction of the lifting frame 65 and prevents it from shaking during movement. A rotary motor 67 is installed at the upper end of the lifting frame 65. Its output shaft is connected to the rotating frame 68 through a gearbox. The function of the gearbox is to adjust the output speed and torque of the rotary motor 67 to meet the working requirements of the rotating frame 68. The magnetic disk 69 has a certain magnetism and can attract the detection bolt 5, making it rotate with the rotating frame 68. The magnetic disk 69 uses neodymium iron boron N52 grade or samarium cobalt high magnetic force magnets, and laser micro-textures are set on the contact surface with the detection bolt 5, with dense diamond-shaped pits to increase friction.

[0036] The measuring component 8 includes a connecting frame 81, a locking block 82, a fixing rod 83, and a fixing plate 84.

[0037] The mounting housing 1 has a sliding connection of a connecting frame 81, and a locking block 82 is fixedly connected to the lower end of the connecting frame 81. The connecting frame 81 also has a sliding connection of a fixing rod 83, which is fixedly connected to the mounting housing 1. A fixing plate 84 is fixedly connected to the side wall of the connecting frame 81, and the fixing plate 84 is connected to the mounting housing 1 by bolts.

[0038] By loosening the bolts on the fixing plate 84, the limiting position of the fixing plate 84 is released, making it easier to adjust the height of the locking block 82 through the connecting bracket 81. The locking block 82 is locked in the rod of the detection bolt 5, and the diameter of the rod of the detection bolt 5 is measured.

[0039] The mounting housing 1 has scale lines on its side wall.

[0040] The scale line serves as a reference for the measuring component 8. When the locking block 82 locks the testing bolt 5, the operator can directly read the diameter value of the testing bolt 5 by observing the position of the connecting bracket 81 relative to the scale line. The accuracy of the scale line can be designed according to actual needs to ensure the accuracy of the measurement results.

[0041] The support components include an elastic plate 3 and a support frame 4.

[0042] Multiple elastic plates 3 are evenly distributed on the outer side of the conveyor belt 2. Support frames 4 are fixedly connected to the outer side of each elastic plate 3. The support frames 4 are in contact with the detection bolts 5.

[0043] The elastic plate 3 has a certain degree of elasticity and can deform when subjected to external force. When the external force disappears, it can return to its original shape. The upper end of the support frame 4 is V-shaped and matches the rod of the detection bolt 5, which can support the detection bolt 5. When the detection bolt 5 is placed on the conveyor belt 2, the support frame 4 will contact the detection bolt 5 to support detection bolts 5 of different diameters. At the same time, the elastic plate 3 can reduce vibration and impact during transportation and ensure the stability of the detection bolt 5.

[0044] A detection camera 7 is installed on the inner top of the mounting housing 1.

[0045] The inspection camera 7 is a device capable of capturing images. Its lens is directed towards the inspection bolt 5 on the conveyor belt 2. When the inspection bolt 5 moves with the conveyor belt 2 into the shooting range of the inspection camera 7, the inspection camera 7 will capture an image and transmit the captured image to the subsequent image processing system. The image processing system will analyze the image and use image recognition technology to detect whether there are defects such as cracks or breaks on the surface of the inspection bolt 5, thereby realizing the fracture detection of the inspection bolt 5. The resolution and shooting speed of the inspection camera 7 can be selected according to actual needs to ensure the accuracy and efficiency of the detection.

[0046] The working principle of this utility model is as follows: A mark is made on the end of the inspection bolt 5, and the inspection bolt 5 is placed on the upper end of the support frame 4 by a robotic arm. The conveyor belt 2 drives the support frame 4 and the inspection bolt 5 to move through the elastic plate 3. When the inspection bolt 5 moves to the working position of the rotating component 6, the first electric push rod 61 is energized, and its output end extends, driving the moving block 62 to move horizontally. The second electric push rod 64 is energized, and its output end extends, driving the lifting frame 65 to rise and fall, so that the center of the magnetic disk 69 is aligned with the center of the inspection bolt 5. The rotating motor 67 is started, and its output shaft drives the rotating frame 68 to rotate through the gearbox. The rotating frame 68 drives the magnetic disk 69 and the inspection bolt 5 to rotate synchronously, so that all surfaces of the inspection bolt 5 can be fully inspected. During the rotation, the inspection camera 7 will take pictures of the rotating inspection bolt 5 to obtain images of it from different angles for subsequent comprehensive defect inspection. When the mark on the end of the inspection bolt is captured twice, it means that the shooting is completed. The robotic arm classifies the inspected inspection bolt 5.

[0047] After the test is completed, the first electric push rod 61 is rotated to drive the rotating assembly 6 to move away from the test bolt 5. The support frame 4 limits the test bolt 5, so that the magnetic disk 69 can be separated from the test bolt 5.

[0048] When the detection bolt 5 moves to the working position of the measuring component 8, the bolts on the fixing plate 84 are loosened, releasing the limitation on the fixing plate 84, making it easier to adjust the height of the clamping block 82 through the connecting frame 81. The clamping block 82 is clamped on the rod of the detection bolt 5, and the diameter of the rod of the detection bolt 5 is measured. The diameter value is read through the scale line. Then the clamping block 82 is moved up and fixed. The device is suitable for large-scale testing of the same type of detection bolt 5. Otherwise, the diameter testing process will affect the testing efficiency.

[0049] In this application, the control method of the conveyor belt 2, the first electric push rod 61, the second electric push rod 64, the rotary motor 67, and the detection camera 7 is to be automatically controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0050] 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.
