Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine blade technology, and in particular to a positioning and inspection tooling for pultruded beams of wind turbine blades. Background Technology
[0002] Pultruded beams are the main structure of wind turbine blades and serve as the primary load-bearing component. During the manufacturing process of wind turbine blades, each blade requires positioning fixtures to hold the pultruded beam in place. With the rapid development of wind power technology, the aerodynamic shape of wind turbine blades is becoming increasingly complex, and the blade twist angle is increasing, resulting in a larger tilt angle for the pultruded beam. This makes the pultruded beam prone to displacement during shell forming.
[0003] Chinese utility model patent CN220690052U discloses a positioning and inspection fixture for pultruded beams of wind turbine blades, including a base, a fixture body, a sensor, and a display. The base is fixed to the steel frame of the blade shell. One side of the fixture body is fixed to the base, and the other side is placed inside the blade shell and can abut against the pultruded beam. The fixture body conforms to the blade profile. The sensor is located on the side of the fixture body that abuts against the pultruded beam, and the end of the sensor can abut against the pultruded beam. The sensor is used to detect the displacement data of the fixture body and send the detection result to the display. The sensor is connected to the display, and the display is used to display the detection result. This positioning and inspection fixture for pultruded beams of wind turbine blades can perform secondary inspection of the placement position of the pultruded beam using a sensor and a display, ensuring accurate placement without deviation and avoiding quality defects caused by pultruded beam deviation. However, since the main structure of the fixture body is fixed, different sizes of positioning and inspection fixtures are required for different models of wind turbine blades, resulting in poor versatility and increased positioning and inspection costs.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] This utility model embodiment provides a positioning and inspection fixture for pultruded beams of wind turbine blades, such as... Figure 1-2As shown, the fixture includes a main body 1 and a display 6. A base 2 is installed at one end of the main body 1, and the base 2 is fixed on the steel frame of the blade shell 3. A sensor 4 is installed at the other end of the main body 1. The sensor 4 is a displacement sensor, and the end of the sensor 4 can abut against the pultruded beam 5. The sensor 4 is used to detect the displacement data of the main body 1 and send the detection result to the display 6. The display 6 is used to display the detection result. The main body 1 includes a lateral telescopic component 11 for adjusting the lateral distance between the base 2 and the sensor 4 and a longitudinal telescopic component 12 for adjusting the longitudinal distance between the base 2 and the sensor 4, so that the positioning inspection fixture can perform positioning inspection of the pultruded beams of different types of wind turbine blades, which has strong versatility and can reduce the positioning inspection cost.
[0018] In this embodiment, the lateral telescopic component 11 includes a first telescopic tube 111 and a first telescopic rod 112 telescopically disposed inside the first telescopic tube 111. One end of the first telescopic rod 112 extends from inside the first telescopic tube 111 and is fitted with a base 2. A first bolt 113 is threaded onto the first telescopic tube 111 for fixing or loosening the first telescopic rod 112 inside or outside the first telescopic tube 111. The first telescopic rod 112 can extend and retract inside the first telescopic tube 111 to adjust the length of the lateral telescopic component 11. Simultaneously, the first bolt 113 can fix the first telescopic rod 112 inside the first telescopic tube 111, fixing the length of the lateral telescopic component 11, thereby adjusting the lateral distance between the base 2 and the sensor 4. The first telescopic rod 112 is also connected to a first drive mechanism for extending and retracting inside the first telescopic tube 111. More specifically, the first drive assembly 114 includes a first lead screw 1141, a first handle 1142 mounted on one end of the first lead screw 1141, a first lead screw nut 1143 threaded onto the first lead screw 1141, and the first lead screw nut 1143 mounted on one end of the first connecting block 1144. The side wall of the first telescopic tube 111 is provided with a first strip hole 1111 along its central axis. The other end of the first connecting block 1144 passes through the first strip hole 1111 and is connected to the first telescopic rod 112. By rotating the first handle 1142, the first lead screw 1141 can be rotated. The first lead screw 1141 can drive the first connecting block 1144 to slide inside the first strip hole 1111 through the first lead screw nut 1143, thereby allowing the first telescopic rod 112 to extend and retract inside the first telescopic tube 111, thus facilitating the adjustment of the length of the lateral telescopic assembly 11.
[0019] It should be noted that the first telescopic rod 112 and the base 2 are provided with pin holes at opposite positions, and the pin holes of the first telescopic rod 112 and the base 2 are provided with pins for fixing the first telescopic rod 112 and the base 2.
[0020] In this embodiment, the longitudinal telescopic component 12 includes a second telescopic tube 121 and a second telescopic rod 122 telescopically disposed inside the second telescopic tube 121. One end of the second telescopic rod 122 extends out of the second telescopic tube 121 and is fitted with a sensor 4. A second bolt 123 is threaded onto the second telescopic tube 121 for fixing or releasing the second telescopic rod 122 inside or from the second telescopic tube 121. The second telescopic rod 122 can extend and retract inside the second telescopic tube 121 to adjust the length of the transverse telescopic component 12. Simultaneously, the second bolt 123 can fix the second telescopic rod 122 inside the second telescopic tube 121, fixing the length of the transverse telescopic component 12, thereby adjusting the longitudinal distance between the base 2 and the sensor 4. The second telescopic rod 122 is also used to drive its extension and retraction within the second telescopic tube 121. The second drive assembly 124 is connected, more specifically, the second drive assembly 124 includes a second lead screw 1241, a second handle 1242 is installed at one end of the second lead screw 1241, a second lead screw nut 1243 is threaded onto the second lead screw 1241, the second lead screw nut 1243 is installed at one end of the connecting block 1244, the side wall of the second telescopic tube 121 is provided with a second strip hole 1211 along its central axis, the other end of the connecting block 1244 passes through the second strip hole 1211 and is connected to the second telescopic rod 122. By rotating the second handle 1242, the second lead screw 1241 can be driven to rotate, and the second lead screw 1241 can drive the connecting block 1244 to slide inside the second strip hole 121 through the second lead screw nut 1243, thereby allowing the second telescopic rod 122 to extend and retract inside the second telescopic tube 121, thus facilitating the adjustment of the length of the transverse telescopic assembly 12.
[0021] It should be noted that a mounting bracket 13 is installed between the first telescopic tube 111 and the second telescopic tube 121. The two ends of the first lead screw 1141 are rotatably mounted on the mounting bracket 13 through the first bearing 1145. The two ends of the second lead screw 1241 are rotatably mounted on the mounting bracket 13 through the second bearing 1245. The display 6 is mounted on one side of the mounting bracket 13.
[0022] Specific principle: When performing positioning inspection on the pultruded beam 5, the base 2 is fixed on the steel frame of the blade shell 3. Rotating the first handle 1142 causes the first lead screw 1141 to rotate. The first lead screw 1141, through the first lead screw nut 1143, drives the first connecting block 1144 to slide inside the first slotted hole 1111, thereby extending and retracting the first telescopic rod 112 inside the first telescopic tube 111. This adjusts the length of the lateral telescopic assembly 11, thus adjusting the lateral distance between the base 2 and the sensor 4. Rotating the second handle 1242 causes the second lead screw 1241 to rotate. The second lead screw 1241, through the second lead screw nut 1243, drives the connecting block 1244 inside the second slotted hole 1211. The second telescopic rod 122 can slide and extend inside the second telescopic tube 121, thereby adjusting the length of the longitudinal telescopic component 12. This allows adjustment of the longitudinal distance between the base 2 and the sensor 4, so that the end of the sensor 4 can abut against the pultruded beam 5. After adjustment, the first telescopic rod 112 is fixed inside the first telescopic tube 111 by the first bolt 113, and the second telescopic rod 122 is fixed inside the second telescopic tube 121 by the second bolt 123. This fixes the overall structure of the tooling body 1. The sensor 4 can detect the displacement data of the tooling body 1 and send the detection results to the display 6. The display 6 is used to display the detection results and determine whether the position of the tooling body 1 has shifted. Based on this data, the position of the pultruded beam 5 is checked a second time.
[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
