Description

Technical Field

[0001] This utility model relates to the field of wind turbine impeller testing technology, and specifically to a wind turbine impeller testing platform. Background Technology

[0002] As a widely used power equipment in the industrial field, the machining accuracy and balance performance of the impeller, a core component of Roots blowers, directly affect the blower's operating efficiency and service life. Traditional impeller inspection usually relies on fixed inspection fixtures combined with handheld measuring instruments, which suffers from problems such as cumbersome operation, low inspection efficiency, and poor repeatability. Especially for impellers of different specifications, existing inspection platforms generally lack adaptive adjustment capabilities for height and clamping range, resulting in the need to change fixtures or manually adjust sensor positions during the inspection process. This not only increases labor intensity but also makes it easy for human error to affect the reliability of the inspection data.

[0003] In the existing technology, a fixed support platform is used in conjunction with a manually adjustable clamping mechanism. Although this achieves the basic clamping function, it cannot meet the rapid positioning requirements of impellers with different diameters and thicknesses. Furthermore, during the detection process, the sensor needs to be manually moved to perform multi-point measurements, making it difficult to ensure the consistency of the detection path.

[0004] For example, although a motor-driven slide rail structure is introduced into the inspection platform, its detection sensors can only move in a single direction, failing to achieve precise positioning in three-dimensional space and thus lacking adaptability for inspecting impeller surfaces with complex contours. Furthermore, traditional clamping mechanisms often use rigid contact surfaces, which can easily scratch the impeller surface during clamping, affecting the yield of finished products.

[0005] To address the aforementioned issues, a dedicated testing platform integrating height adjustment, multi-directional clamping adaptive design, and automated detection path planning needs to be designed to improve the accuracy and efficiency of Roots blower impeller testing, achieve clamping and testing of various impellers, and save production costs. Utility Model Content

[0006] The purpose of this invention is to provide a wind turbine impeller testing platform to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine impeller testing platform, comprising a base, a testing platform, a lifting assembly, and a clamping assembly, characterized in that: anchor bolts for fixing to the ground are provided below the base, and a lifting assembly and a processing table are respectively provided above it; the lifting assembly fixes and supports the testing platform above; a drive motor is provided at the center below the testing platform, and the output shaft of the drive motor passes through the testing platform and connects to a rotating seat provided above it; a clamping assembly is fixedly provided on one side above the testing platform; a first slide rail is provided above the processing table, one end of the first slide rail is driven by a first motor, and a testing support frame is provided above the first slide rail for sliding connection; the other end of the testing support frame is fixedly connected to a second slide rail, one end of the second slide rail is driven by a second motor, a slider is provided on the second slide rail for sliding connection, and a testing sensor is fixedly connected above the slider.

[0008] Preferably, the lifting assembly includes a lifting frame and a lifting hydraulic rod. The lifting hydraulic rod drives the lifting frame to slide and lift, thereby adjusting the lifting height of the detection platform to facilitate the detection of impellers at different heights.

[0009] Preferably, the clamping assembly includes a clamping slide rail, a first clamping plate, a second clamping plate, a first hydraulic rod, a second hydraulic rod, and clamping blocks. The clamping slide rail is fixedly disposed on one side of the upper surface of the detection platform, and the first clamping plate and the second clamping plate are slidably connected on its upper two sides. The first clamping plate is fixedly disposed on the first clamping plate, and the output end of the first hydraulic rod is fixedly disposed on one side of the clamping slide rail to drive the first clamping plate to move laterally on the clamping slide rail. Similarly, the second clamping plate is the same as the first clamping plate. Four clamping blocks are evenly disposed on the inner side of the first clamping plate and the second clamping plate for clamping the fan impeller.

[0010] Preferably, the first slide rail is horizontally fixed on the processing table, and the detection support frame slidably connected above it is an arc-shaped right-angle structure. The second slide rail connected at the other end is in a vertical state, which facilitates the detection of impellers of different heights by the vertical movement of the slider and the detection of impellers of different widths by the detection sensor.

[0011] Preferably, the drive motor is connected to the rotating base via an output shaft and is used to detect the rotation of the impeller.

[0012] Preferably, the surface of the clamping block is provided with a rubber protective layer to improve the stability of the impeller detection clamping.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model employs a lifting assembly that links the lifting hydraulic rod with the lifting frame, combined with a bidirectional slide rail structure on the processing table, to achieve three-dimensional linkage adjustment of the height of the detection platform and the spatial position of the detection sensor. Through the coordinated operation of the lateral movement of the first slide rail and the vertical movement of the second slide rail, the detection sensor can automatically complete a full circumferential scan of the impeller along a preset trajectory, effectively solving the measurement blind zone problem present in traditional single-degree-of-freedom detection systems. It is particularly suitable for detecting impeller profiles with complex curved surface features.

[0015] 2. The innovative clamping assembly uses dual hydraulic rods to drive the clamping plate to make symmetrical displacement on the slide rail. Combined with the four-jaw clamping block with a rubber protective layer on the surface, it achieves radial adaptive compensation while ensuring clamping rigidity. This structure is compatible with impellers of different specifications. The clamping contact area is significantly increased compared with traditional clamps. It can avoid surface damage caused by rigid clamping and eliminate assembly gaps through elastic deformation compensation, thereby improving the positioning accuracy of the impeller.

[0016] 3. The coaxial arrangement of the testing platform and the drive motor forms a rotary testing station. Through spatial coordination with the movable detection sensor, a combined dynamic and static testing mode is constructed. When the rotating seat drives the impeller to rotate at a constant speed, the detection sensor can simultaneously perform axial displacement, realizing continuous measurement of dynamic eccentricity and end face runout. This method is several times more efficient than the traditional static testing method and can capture instantaneous vibration data.

[0017] 4. The overall design adopts a modular approach. The base, secured by anchor bolts, forms a stable testing reference surface with the processing table. The lifting assembly, clamping assembly, and slide rail system constitute an expandable functional unit. This structure ensures system rigidity during heavy-duty impeller testing and allows for rapid adaptation to new impeller specifications by adjusting the slide rail stroke parameters, reducing equipment modification time and production costs.

[0023] The detection assembly includes a first slide rail 9 arranged horizontally on the upper surface of the processing table 5. The first slide rail 9 is driven by a first motor 10. An arc-shaped right-angle detection support frame 11 is slidably connected to the first slide rail 9. The end of the detection support frame 11 is fixedly and vertically connected to a second slide rail 12. The second slide rail 12 is driven by a second motor. A slider 14 is provided on the second slide rail 12 for sliding connection. A detection sensor 15 is installed on the top of the slider 14.

[0024] The top end of the lifting assembly is rigidly connected to the detection platform 4. A drive motor 6 is fixedly installed below the center of the detection platform 4. The output shaft of the drive motor 6 vertically passes through the detection platform 4 and is connected to the rotating seat 7. A clamping assembly is installed at the rear end of the upper surface of the detection platform 4.

[0025] The lifting assembly consists of a lifting frame 31 composed of four columns and at least two lifting hydraulic rods 32 arranged in parallel. The piston end of the lifting hydraulic rod 32 is hinged to the middle section of the lifting frame 31. The lifting frame 31 is vertically raised and lowered along the guide rail of the base 1 by a synchronous hydraulic system, so that the height of the detection platform 4 can be adjusted when the height cannot be adjusted.

The first hydraulic rod 84 is fixedly installed on the first clamping plate 82, and its output end is fixedly installed on one side of the clamping slide rail 81. The first clamping plate 82 is hydraulically driven by the first hydraulic rod 84 to move laterally on the clamping slide rail 81. Similarly, the second clamping plate 83 works on the same principle as the first clamping plate 82. Four clamping blocks 86 are evenly arranged on the inner side of the first clamping plate 82 and the second clamping plate 83. Each clamping block 86 has a 3mm thick anti-slip rubber layer 861 on its surface to improve the stability of the clamping effect. The movement adjustment of the first clamping plate 82 and the second clamping plate 83 can adapt to different diameter fan impellers, thereby improving work efficiency and reducing production costs.

[0027] Working principle: First, start the lifting hydraulic rod 32 to adjust the detection platform 4 to the appropriate height for impeller installation. Then, operate the first hydraulic rod 84 and the second hydraulic rod 85 on the clamping slide rail 81 to make the clamping blocks 86 on the first clamping plate 82 and the second clamping plate 83 clamp the impeller hub. Drive the detection support frame 11 to move laterally to the impeller frame through the first motor 10. Adjust the slider 14 and the detection sensor 15 to move vertically to the center of the impeller. The detection sensor 15 touches the impeller frame. Finally, start the drive motor 6 to drive the impeller to rotate, thereby performing a comprehensive inspection of the impeller.
