Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade manufacturing equipment, and in particular to a tensioning tooling for a blade pultruded beam cap. Background Art

[0002] Wind turbine blades (also known as wind generator blades or wind blades) are key components in wind turbine generators that capture wind energy. They are responsible for converting the natural wind energy into mechanical energy and then converting it into electrical energy through a generator. Their performance directly determines the power generation efficiency and economic benefits of the unit. The pultruded beam cap refers to the main beam part of the wind turbine blade manufactured by the pultrusion process, usually called the beam cap or the main beam. It is the main load-bearing structure of the wind turbine blade, similar to the keel of a ship, responsible for supporting the blade and bearing the loads generated by the wind.

[0003] Due to the change in the pultruded beam cap forming process, from prefabricated beam caps to integrated pouring of beam cap shells, before pouring, the pultruded plate needs to present the specific shape of the original prefabricated beam. To achieve this purpose, a tooling with a certain profile, that is, a tensioning tooling, needs to be designed. The tensioning tooling uses the profile of the tooling and the tension of the binding straps to make the pultruded plate present a specific tooling. When the existing tensioning tooling for blade pultruded beam caps is in use, generally, a certain pressure is applied to the pultruded beam cap through a pressing plate, and then the pultruded beam cap is tensioned through a tensioning belt. Its disadvantages are: 1. The two steps cannot be completed at one time, which prolongs the production cycle; 2. The pressing plate and the tensioning belt cannot apply pressure to the beam cap simultaneously, and there may be many pressure blind spots; 3. The step-by-step operation causes the stress of the pultruded beam cap to redistribute or the layers to be misaligned. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above technical deficiencies and propose a tensioning tooling for a blade pultruded beam cap to solve the technical problems that when the existing tensioning tooling for a blade pultruded beam cap is in use, generally, a certain pressure is applied to the pultruded beam cap through a pressing plate, and then the pultruded beam cap is tensioned through a tensioning belt. Its disadvantages are: 1. The two steps cannot be completed at one time, which prolongs the production cycle; 2. The pressing plate and the tensioning belt cannot apply pressure to the beam cap simultaneously, and there may be many pressure blind spots; 3. The step-by-step operation causes the stress of the pultruded beam cap to redistribute or the layers to be misaligned.

[0005] To achieve the above technical objectives, the technical solution of the present invention provides a tensioning tooling for a pultruded beam cap of a blade, which includes a cross beam and a pressing plate arranged below the cross beam. The pressing plate is connected to the cross beam through a lifting mechanism. The bottom of the pressing plate is provided with a pultruded beam cap profile. The tensioning tooling further includes a tensioning belt. One end of the tensioning belt is connected to one end of the cross beam, and the other end of the tensioning belt bypasses the pressing plate from below and is connected to a traction mechanism. The lifting mechanism includes a threaded sleeve installed in the middle of the cross beam through a bearing. A threaded rod is threadedly connected inside the threaded sleeve. The lifting mechanism further includes guide rods installed at both ends of the pressing plate. Guide holes are provided at both ends of the cross beam, and the two guide rods are respectively movably arranged inside the two guide holes. The traction mechanism includes a traction wheel rotatably installed on the cross beam through a bearing. The other end of the tensioning belt is wound around the traction wheel. A linkage assembly is connected between the traction wheel and the threaded sleeve. The linkage assembly can make the threaded sleeve and the traction wheel rotate synchronously, so that the pressing plate and the tensioning belt can apply pressure and tension to the pultruded beam cap simultaneously.

[0006] Further, the linkage assembly includes a worm gear installed on the threaded sleeve. The worm gear meshes with a worm. The worm is installed on the cross beam through a bearing. One end of the worm meshes with a first bevel gear. The first bevel gear meshes with a second bevel gear. The second bevel gear is connected to the traction wheel.

[0007] Further, the threaded sleeve is connected to a driving mechanism for driving the threaded sleeve to rotate.

[0008] Further, the driving mechanism includes a driven gear installed on the threaded sleeve. The driven gear is connected to a driving gear. The driving gear is connected to a driving device for driving the driving gear to rotate.

[0009] Further, the driving device adopts a motor.

[0010] Further, a pressure sensor is installed between the pressing plate and the threaded rod. A tension sensor is provided on the tensioning belt. The pressure sensor, the tension sensor and the driving mechanism are respectively electrically connected to a controller.

[0011] Further, one end of the tensioning belt is detachably connected to one end of the cross beam through a connection assembly.

[0012] Further, the connection assembly includes a connection post installed at one end of the tensioning belt. The connection assembly further includes inverted L-shaped connection blocks installed on both sides of the top of one end of the cross beam and cooperating with the connection post.

[0013] Further, adjusting bolts for pushing both ends of the connection post to move inside the two connection blocks are threadedly connected to both connection blocks.

[0014] Further, guide rollers are rotatably installed at both ends of the pressing plate. The tensioning belt is wound around the guide rollers.

[0015] The beneficial effects of the present invention include: 1. The linkage component can make the threaded sleeve and the traction wheel rotate synchronously, so that the pressure plate and the tensioning belt can apply pressure and tension to the pultruded beam cap at the same time, and can complete the pressurization of the pultruded beam cap at one time, shortening the production cycle and being suitable for batch manufacturing. The pressure plate provides local high pressure to the pultruded beam cap, and the tensioning belt provides overall uniform tension to the pultruded beam cap. The two work together to reduce the pressure blind area and also avoid stress redistribution or interlayer misalignment caused by step-by-step operation; 2. When the pressure value of the pressure sensor and the tension value of the tension sensor are respectively within appropriate ranges, the controller controls the driving mechanism to stop driving the threaded sleeve to rotate, so that the pressure value of the pressure sensor and the tension value of the tension sensor are maintained within appropriate ranges, thereby controlling the pressure of the pressure plate on the pultruded beam cap and the tension of the tensioning belt on the pultruded beam cap, and keeping the pressure of the pressure plate on the pultruded beam cap and the tension of the tensioning belt on the pultruded beam cap within appropriate ranges. Compared with the traditional manual operation method, it can not only save labor, reduce the intensity of the tensioning work of the pultruded beam cap, but also has high precision. Therefore, the pultruded beam cap can be better tensioned; 3. The adjusting bolt can push the connecting column to move inside the connecting block to adjust the tension of the tensioning belt, so as to adjust the tension of the tensioning belt on the pultruded beam cap, so that while controlling the pressure of the pressure plate on the pultruded beam cap within an appropriate range, the tension of the tensioning belt on the pultruded beam cap can be controlled within an appropriate range.

Detailed implementation mode

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0018] An embodiment of the present invention provides a tensioning tool for a blade pultruded beam cap, as Figure 1-2 described, including a cross beam 1 and a pressing plate 2 provided below the cross beam 1. The pressing plate 2 is connected to the cross beam 1 through a lifting mechanism 3. A pultruded beam cap profile is provided at the bottom of the pressing plate 2. The tensioning tool further includes a tension belt 4. One end of the tension belt 4 is connected to one end of the cross beam 1, and the other end of the tension belt 4 bypasses the pressing plate 2 from below the pressing plate 2 and is connected to a traction mechanism 5.

[0019] In this embodiment, the lifting mechanism 3 includes a threaded sleeve 31 installed in the middle of the cross beam 1 through a bearing. A threaded rod 32 is threadedly connected inside the threaded sleeve 31. The lifting mechanism 3 further includes guide rods 33 installed at both ends of the pressing plate 2. Guide holes are provided at both ends of the cross beam 1, and the two guide rods 33 are respectively movably arranged inside the two guide holes. When the threaded sleeve 31 rotates, the threaded sleeve 31 can drive the threaded rod 32 to lift or lower, and the threaded rod 32 can drive the pressing plate 2 to lift or lower, applying pressure to the pultruded beam cap. The traction mechanism 5 includes a traction wheel 51 rotatably installed on the cross beam 1 through a bearing. The other end of the tension belt 4 is wound around the traction wheel 51. When the traction wheel 51 rotates, the traction wheel 51 can traction the tension belt 4, and at the same time, the tension belt 4 applies a tension force to the pultruded beam cap. The traction wheel 51 and the threaded sleeve 31 are connected through a linkage assembly 6. The linkage assembly 6 can make the threaded sleeve 31 and the traction wheel 51 rotate synchronously, so that the pressing plate 2 and the tension belt 4 can apply pressure and tension force to the pultruded beam cap at the same time, which can complete the pressurization of the pultruded beam cap at one time, shorten the production cycle, and is suitable for batch manufacturing. The pressing plate 2 provides local high pressure to the pultruded beam cap, and the tension belt 4 provides overall uniform tension force to the pultruded beam cap. The two cooperate to reduce the pressure blind area, and at the same time, it can also avoid stress redistribution or interlayer dislocation caused by step-by-step operation.

[0020] It should be noted that an installation hole is provided in the middle of the cross beam 1, and the lower end of the threaded sleeve 31 is rotatably installed inside the installation hole through a bearing.

[0021] It should be noted that guide rollers 21 are rotatably installed at both ends of the pressing plate 2, and the tension belt 4 is wound around the guide rollers 21. By means of the guide rollers 21, the friction between the tension belt 4 and both ends of the pressing plate 2 can be reduced, avoiding the tension belt 4 from being worn out due to excessive friction between the tension belt 4 and both ends of the pressing plate 2 during the process of tightening the pultruded beam cap.

[0022] In this embodiment, the linkage assembly 6 includes a worm gear 601 installed on the threaded sleeve 31. The worm gear 601 meshes with a worm 602. The worm 602 is installed on the cross beam 1 through a bearing. One end of the worm 602 meshes with a first bevel gear 603. The first bevel gear 603 meshes with a second bevel gear 604. The second bevel gear 604 is connected to the traction wheel 51. When the threaded sleeve 31 rotates, the threaded sleeve 31 can drive the worm gear 601 to rotate. The worm gear 601 can drive the worm 602 to rotate. The worm 602 can drive the first bevel gear 603 to rotate. The first bevel gear 063 can drive the second bevel gear 604 to rotate, so as to drive the traction wheel 51 to rotate, that is, the threaded sleeve 31 and the traction wheel 51 can rotate synchronously.

[0023] For the linkage assembly 6, it only needs to meet the requirement of being able to make the threaded sleeve 31 and the traction wheel 51 rotate synchronously. Therefore, it is not limited to a certain specific structure. For example, in some other embodiments, such as Figure 3As shown in the figure, the linkage assembly 6 includes a first gear 611 installed on the threaded sleeve 31. The first gear 611 meshes with a second gear 612. The second gear 612 meshes with a third bevel gear 614 through a first connecting rod 613. The third bevel gear 614 meshes with a fourth bevel gear 615. The fourth bevel gear 615 is connected to a fifth bevel gear 617 through a second connecting rod 616. The fifth bevel gear 617 meshes with a sixth bevel gear 618. The sixth bevel gear 618 is connected to the traction wheel 51. When the threaded sleeve 31 rotates, the threaded sleeve 31 can drive the first gear 611 to rotate. The first gear 611 can drive the second gear 612 to rotate. The second gear 612 can drive the third bevel gear 614 to rotate through the first connecting rod 613. The third bevel gear 63 can drive the fourth bevel gear 615 to rotate. The fourth bevel gear 615 can drive the fifth bevel gear 617 to rotate through the second connecting rod 616. The fifth bevel gear 617 can drive the sixth bevel gear 618 to rotate, thereby driving the traction wheel 51 to rotate, that is, the threaded sleeve 31 and the traction wheel 51 can rotate synchronously.

[0024] In this embodiment, the threaded sleeve 31 is connected to a driving mechanism 7 for driving the threaded sleeve 31 to rotate. More specifically, the driving mechanism 7 includes a driven gear 71 installed on the threaded sleeve 31. The driven gear 71 is connected to a driving gear 72. The driving gear 72 is connected to a driving device 73 for driving the driving gear 72 to rotate. The driving device 73 is installed on the top of the cross beam 1. By the driving device 73, the driving gear 72 can be driven to rotate. The driving gear 72 can drive the driven gear 71 to rotate, thereby driving the threaded sleeve 31 to rotate.

[0025] In this embodiment, the driving device 73 adopts an electric motor.

[0026] For the driving device 73, it only needs to be able to drive the driving gear 72 to rotate. Therefore, it is not limited to the form of an electric motor. For example, in some other embodiments, the driving device 73 adopts a hydraulic motor or a pneumatic motor and other driving parts that can drive the driving gear 72 to rotate.

[0027] In this embodiment, a pressure sensor 22 is installed between the pressing plate 2 and the threaded rod 32. Through the pressure sensor 22, the pressure exerted by the threaded rod 32 on the pressing plate 2 can be detected to facilitate controlling the pressure exerted by the pressing plate 2 on the pultruded beam cap. A tension sensor 41 is provided on the tension belt 4. Through the tension sensor 41, the tension of the traction wheel 51 on the tension belt 4 can be detected to facilitate controlling the tension force exerted by the tension belt 4 on the pultruded beam cap, such as Figure 4As shown, a pressure sensor 22, a tension sensor 41, and a driving mechanism 7 are electrically connected to a controller 8 respectively. The pressure sensor 22 and the tension sensor 41 can send the detected signals to the controller 8, and the controller 8 can control the driving mechanism 7 according to the detected signals. When the pressure value of the pressure sensor 22 and the tension value of the tension sensor 41 are respectively within appropriate ranges, the controller 8 controls the driving mechanism 7 to stop driving the threaded sleeve 31 to rotate, so that the pressure value of the pressure sensor 22 and the tension value of the tension sensor 41 are maintained within appropriate ranges, thereby controlling the pressure of the pressing plate 2 on the pultruded beam cap and the tension of the tension belt 4 on the pultruded beam cap, and keeping the pressure of the pressing plate 2 on the pultruded beam cap and the tension of the tension belt 4 on the pultruded beam cap within appropriate ranges. Compared with the traditional manual operation method, it can not only save labor, reduce the intensity of the tensioning work of the pultruded beam cap, but also has high precision. Therefore, the pultruded beam cap can be tensioned better.

[0028] In this embodiment, one end of the tension belt 4 is detachably connected to one end of the cross beam 1 through a connecting component 9. More specifically, the connecting component 9 includes a connecting column 91 installed at one end of the tension belt 4. The connecting component 9 further includes inverted L-shaped connecting blocks 92 installed on both sides of the top of one end of the cross beam 1 and cooperating with the connecting column 91. Both ends of the connecting column 91 are respectively clamped inside the two connecting blocks 92. When the pultruded beam cap is tied to the bottom of the pressing plate 2, both ends of the connecting column 91 are taken out from inside the two connecting blocks 92, and then the tension belt 4 can be detached from one end of the cross beam 1. After the tension belt 4 is detached from one end of the cross beam 1, the pultruded beam cap is placed at the bottom of the pressing plate 2. After the pultruded beam cap is placed at the bottom of the pressing plate 2, both ends of the connecting column 91 are respectively inserted into the two connecting blocks 92, thereby connecting one end of the tension belt 4 to one end of the cross beam 1, and the pultruded beam cap can be pre-fixed at the bottom of the pressing plate 2. The operation is convenient. At the same time, after the tension belt 4 is used for a period of time, the tension belt 4 can be stretched and cannot be restored. Therefore, while the pressure of the pressing plate 2 on the pultruded beam cap is controlled within an appropriate range, the tension of the tension belt 4 on the pultruded beam cap cannot be controlled within an appropriate range. In this embodiment, as Figure 5 shown, adjusting bolts 921 for pushing both ends of the connecting column 91 to move inside the two connecting blocks 92 are threadedly connected to both of the connecting blocks 92. When the adjusting bolts 921 are rotated, the adjusting bolts 921 can push the connecting column 91 to move inside the connecting blocks 92 to adjust the tension of the tension belt 4, thereby adjusting the tension of the tension belt 4 on the pultruded beam cap, so that while the pressure of the pressing plate 2 on the pultruded beam cap is controlled within an appropriate range, the tension of the tension belt 4 on the pultruded beam cap is controlled within an appropriate range.

[0029] It should be noted that the connecting block 92 includes a longitudinal part installed on the top of the cross beam 1 and a transverse part provided at the upper end of the longitudinal part. The longitudinal part and the transverse part are integrally formed and form an inverted L-shaped structure. A threaded hole is provided on the longitudinal part, and the adjusting bolt 921 is threadedly connected inside the threaded hole.

[0030] Specific principle: Pre-fix the pultruded beam. Take out both ends of the connecting column 91 from inside the two connecting blocks 92, so as to remove one end of the tensioning belt 4 from one end of the cross beam 1. Place the tensioning tool above the pultruded beam and make the profile at the bottom of the pressing plate 2 coincide with the upper surface radian of the pultruded beam cap. Pass one end of the tensioning belt 4 around the bottom of the pultruded beam cap, and respectively snap both ends of the connecting column 91 into the two connecting blocks 92, then the pultruded beam cap can be pre-fixed at the bottom of the pressing plate 2.

[0031] Tension the pultruded beam: Drive the threaded sleeve 31 to rotate through the driving mechanism 7. The threaded sleeve 31 can drive the threaded rod 32 to move up and down, and the threaded rod 32 can drive the pressing plate 2 to move up and down to apply pressure to the pultruded beam cap. At the same time, the threaded sleeve 31 can drive the worm gear 601 to rotate, the worm gear 601 can drive the worm 602 to rotate, the worm 602 can drive the first bevel gear 603 to rotate, and the first bevel gear 603 can drive the second bevel gear 604 to rotate, thereby driving the traction wheel 51 to rotate. When the traction wheel 51 rotates, the traction wheel 51 can traction the tensioning belt 4, and at the same time the tensioning belt 4 applies a tensioning force to the pultruded beam cap. Thus, the pressing plate 2 and the tensioning belt 4 can apply pressure and tensioning force to the pultruded beam cap at the same time. The tension sensor 41 can detect the tension of the traction wheel 51 on the tensioning belt 4 to facilitate controlling the tensioning force applied by the tensioning belt 4 to the pultruded beam cap. The pressure sensor 22 and the tension sensor 41 can send the detected signals to the controller 8. The controller 8 can control the driving mechanism 7 according to the detected signals. When the pressure value of the pressure sensor 22 and the tension value of the tension sensor 41 are respectively within appropriate ranges, the controller 8 controls the driving mechanism 7 to stop driving the threaded sleeve 31 to rotate, so that the pressure value of the pressure sensor 22 and the tension value of the tension sensor 41 are maintained within appropriate ranges, thereby controlling the pressure of the pressing plate 2 on the pultruded beam cap and the tensioning force of the tensioning belt 4 on the pultruded beam cap, and keeping the pressure of the pressing plate 2 on the pultruded beam cap and the tensioning force of the tensioning belt 4 on the pultruded beam cap within appropriate ranges to tension the pultruded beam cap.

[0032] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included within the protection scope of the claims of the present invention.
