Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing, and in particular to a segmented wind turbine tower internal platform structure. Background Technology

[0002] With the continued growth of global demand for clean energy, wind power, as a green and sustainable energy acquisition method, has been widely used and developed. As an important component of wind turbine generators, wind turbine towers bear the heavy responsibility of supporting key components such as nacelles and blades. During the manufacturing process of wind turbine towers, many necessary components need to be installed in the internal space of each tower section, such as ladders and cable fixing clips, to securely install them on the inner wall of the tower section, so as to ensure the safe and stable operation of the wind turbine generator and efficient power transmission. Currently, when installing components inside wind turbine tower sections, the common practice is to place and fix the sections horizontally. While this reduces the construction height and allows workers to directly access the interior, it still presents several challenges. Due to the large diameter of the tower sections, some components are installed at considerable distances from the ground, requiring workers to build assembly platforms. However, most existing assembly platforms are modular, necessitating relocation after each task, which is time-consuming, increases labor costs, and reduces construction efficiency. Furthermore, when installing components at higher positions on the inner wall of the tower, existing platforms cannot meet the height and work area requirements, necessitating additional splicing operations. This further increases the complexity and difficulty of construction and may pose safety hazards such as unstable splicing, severely impacting the progress and quality of component installation inside the wind turbine tower.

[0003] Therefore, it is necessary to provide a new segmented wind turbine tower internal platform structure to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a segmented wind turbine tower internal platform structure.

[0005] The segmented wind turbine tower internal platform structure provided by this utility model includes: a tower body, moving wheels, a traveling assembly, support wheels, extension plates, and expansion assemblies. Inside the tower body, there is a support plate for supporting workers' operations and a support frame installed below the support plate. Moving wheels for movement are installed inside the support frame. A traveling assembly is installed between the support frame and the moving wheels. The traveling assembly drives the moving wheels to rotate for movement inside the tower body during operations. Support wheels supporting the inner wall of the tower body are provided at opposite corners of the support frame. Extension plates are symmetrically installed at the bottom of the support plate. An expansion assembly is installed between the support frame and the extension plates. The expansion assembly drives the extension plates to move to expand the support area.

[0006] Preferably, the walking assembly includes: a motor, a worm gear, and a worm wheel. The motor is fixedly connected inside the support frame, the output end of the motor is fixedly connected to the worm gear, the worm wheel is meshed below the worm gear, and a transmission rod is fixedly connected to the shaft of the worm wheel, and the transmission rod is rotatably connected to the inside of the support frame.

[0007] Preferably, both ends of the transmission rod are fixedly connected to a drive sprocket, and both ends of the shaft of the moving wheel are fixedly connected to a driven sprocket. The drive sprocket and the driven sprocket are connected by a chain drive.

[0008] Preferably, threaded sleeves are rotatably connected at the diagonal corners of the support frame, and screws are threadedly connected inside the threaded sleeves. A square groove is opened at the axis of the screw, and a square rod is slidably connected to the inner wall of the square groove. The other end of the square rod passes through the inside of the threaded sleeve and is fixedly connected to the support frame.

[0009] Preferably, the extension assembly includes: an electric push rod, a slide rail, and a slide bar. A mounting plate is symmetrically fixedly connected to the bottom of the support plate. An electric push rod is rotatably connected to the bottom end of each mounting plate. The output end of the electric push rod is hinged to the corresponding extension plate. Two sets of slide rails are symmetrically fixedly connected to the bottom of the support plate. Slide bars are symmetrically fixedly connected to opposite sides of each extension plate. The slide bars are slidably connected to the corresponding slide rails.

[0010] Preferably, a hydraulic push rod is fixedly connected to the top of the support frame, the output end of the hydraulic push rod is fixedly connected to the bottom of the support plate, guide cylinders are fixedly connected to the top diagonal of the support frame, and guide rods corresponding to the guide cylinders are fixedly connected to the bottom of the support plate. The guide rods are all placed inside the corresponding guide cylinders and are slidably connected to their inner walls.

[0011] Preferably, guardrails are fixedly connected to both sides of the extension plate, and a controller is fixedly connected to the side wall of one of the guardrails.

[0012] Compared with related technologies, the segmented wind turbine tower internal platform structure provided by this utility model has the following beneficial effects: The platform is easily moved by its built-in walking components. Operators can efficiently transmit the power of the motor to the moving wheels by operating the controller. There is no need to manually disassemble and assemble the platform. The platform can be moved smoothly inside the tower body by operating the controller. This greatly shortens the time for changing work positions, reduces manpower input, and significantly improves construction efficiency. The height adjustment system, consisting of a hydraulic push rod, guide cylinder, and guide rod, provides stable and powerful lifting power through hydraulic transmission. Combined with the precise guidance of the guide rod and guide cylinder, this allows the support plate to rise and fall smoothly, effectively preventing swaying. Operators can adjust the height on the controller according to their actual working height requirements. The slide rails and slide rods in the extension assembly work together to allow the extension plate to expand smoothly, forming a larger support area with the support plate, further enhancing the platform's load-bearing capacity and stability without requiring complex additional splicing operations. This flexible adjustment method not only expands the platform's working range, covering working areas at different heights within the tower, but also reduces safety risks caused by unstable splicing, making working at heights safer and more efficient. By precisely adjusting the contact between the support wheels and the inner wall of the tower through threaded transmission, a stable four-point support structure is formed, effectively distributing the weight of the platform and workers, ensuring that the platform remains level and stable during operation, and is not prone to swaying or tilting even in complex working environments. At the same time, during platform movement, the support wheels and the moving wheels cooperate with each other, with the support wheels rolling or sliding on the inner wall of the tower, assisting the moving wheels in keeping the platform moving smoothly and preventing deviation. In addition, the guardrails installed on the extension plate provide all-round safety protection for workers, effectively preventing accidental falls. Compared with traditional platforms, the safety performance is greatly improved. Attached Figure Description

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 7 A segmented wind turbine tower internal platform structure includes: a tower body 1, casters 4, a traveling assembly, support wheels 5, extension plates 6, and an expansion assembly. Inside the tower body 1 is a support plate 2 for supporting workers, and a support frame 3 is positioned below the support plate 2. Casters 4 are installed inside the support frame 3 for movement. A traveling assembly is installed between the support frame 3 and the casters 4, driving the casters 4 to rotate for movement inside the tower body 1 during operations. Support wheels 5 are provided at opposite corners of the support frame 3 to support the inner wall of the tower body 1. Extension plates 6 are symmetrically installed at the bottom of the support plate 2. An expansion assembly is installed between the support frame 3 and the extension plates 6, driving the extension plates 6 to move and expand the support area. The traveling assembly includes a motor. 7. Worm 8 and worm wheel 9: A motor 7 is fixedly connected inside the support frame 3. The output end of the motor 7 is fixedly connected to the worm 8. The worm wheel 9 is meshed and connected below the worm 8. A transmission rod 10 is fixedly connected to the axis of the worm wheel 9, and the transmission rod 10 is rotatably connected to the inside of the support frame 3. Both ends of the transmission rod 10 are fixedly connected to the drive sprocket 11. Both ends of the shaft of the moving wheel 4 are fixedly connected to the driven sprocket 12. The drive sprocket 11 and the driven sprocket 12 are connected by chain drive. Threaded sleeves 13 are rotatably connected at the diagonal of the support frame 3. The threaded sleeves 13 are all threadedly connected to the inside of the threaded sleeves 13. A square groove is opened at the axis of the screw 14, and a square rod 15 is slidably connected to the inner wall of the square groove. The other end of the square rod 15 passes through the inside of the threaded sleeve 13 and is fixedly connected to the support frame 3.

[0018] It should be noted that: the support frame 3 is equipped with a battery to power the equipment; the connection between the support wheel 5 and the screw 14 can rotate slightly to adapt to the curvature of the inner wall of the tower body 1 of different sizes; by rotating the threaded sleeve 13, the support wheel 5 installed at the end of the screw 14 gradually approaches and finally makes tight contact with the inner wall of the tower body 1, forming a stable four-point support structure, which firmly fixes the platform inside the tower; the controller 23 controls the motor 7 to start, thereby driving the moving wheel 4 to roll on the inner wall of the tower body 1.

[0019] Please see Figures 3 to 7 The extension components include: electric push rod 16, slide rail 17 and slide rod 18. The bottom of the support plate 2 is symmetrically fixedly connected to the mounting plate. The bottom end of each mounting plate is rotatably connected to the electric push rod 16. The output end of the electric push rod 16 is hinged to the corresponding extension plate 6. The bottom of the support plate 2 is symmetrically fixedly connected to two sets of slide rails 17. The opposite side of each extension plate 6 is symmetrically fixedly connected to the slide rod 18. The slide rod 18 is slidably connected to the corresponding slide rail 17. The top of the support frame 3 is fixedly connected to the hydraulic push rod 19. The output end of the hydraulic push rod 19 is fixedly connected to the bottom of the support plate 2. The top diagonal of the support frame 3 is fixedly connected to the guide cylinder 20. The bottom of the support plate 2 is fixedly connected to the guide rod 21 corresponding to the guide cylinder 20. The guide rod 21 is placed inside the corresponding guide cylinder 20 and slidably connected to its inner wall. The opposite side of each extension plate 6 is fixedly connected to the guardrail 22, and one of the guardrails 22 is fixedly connected to the side wall of the guardrail 22. It should be noted that: the operator directly issues a lifting command on the controller 23, which causes the hydraulic system to start working. Combined with the cooperation of the guide rod 21 and the guide cylinder 20, the support plate 2 rises smoothly in the vertical direction. By controlling the start of the electric push rod 16, its output end pushes the extension plate 6 to move horizontally outward. Combined with the cooperation of the slide rail 17 and the slide rod 18, it provides guidance and support for the movement of the extension plate 6, ensuring that the extension plate 6 expands smoothly and steadily.

[0020] The working principle of the segmented wind turbine tower internal platform structure provided by this utility model is as follows: I. Initial positioning and support

[0021] When operations need to be carried out inside the horizontally fixed tower body 1, the platform is first positioned and stabilized. The threaded sleeve 13 at the diagonal of the support frame 3 is a key adjustment component. By rotating the threaded sleeve 13, the screw 14 extends outward along the axial direction based on the principle of thread transmission. Since the square groove at the axis of the screw 14 slides with the square rod 15 fixed on the support frame 3, the square rod 15 restricts the rotational freedom of the screw 14, allowing it to move only along the axial direction. As the screw 14 extends, the support wheel 5 installed at its end gradually approaches and eventually makes close contact with the inner wall of the tower body 1. The four support wheels 5 form a stable four-point support structure, firmly fixing the platform inside the tower, effectively distributing the weight of the platform and the operators, ensuring that the platform remains horizontal and stable in the initial state, and providing a safe foundation for subsequent operations.

[0022] II. Platform Migration Process

[0023] When the platform needs to be moved to different working positions inside the tower, the walking assembly is activated by the controller 23. The controller 23 sends a command to the motor 7. After the motor 7 is powered on, its output shaft begins to rotate, driving the worm 8 fixed at the output end to rotate synchronously. The helical teeth of the worm 8 mesh with the teeth of the worm wheel 9, converting the rotational motion of the worm 8 into the rotational motion of the worm wheel 9. The transmission rod 10 fixed at the shaft of the worm wheel 9 rotates accordingly. The driving sprockets 11 at both ends of the transmission rod 10 are connected to the driven sprockets 12 at both ends of the shaft of the moving wheel 4 through the chain, forming a chain drive system. When the driving sprocket 11 rotates, the tension of the chain drives the driven sprockets 12 to rotate, thereby driving the moving wheel 4 to roll on the inner wall of the tower body 1. During the movement, the support wheel 5 not only plays a supporting role, but also rolls on the inner wall of the tower, cooperating with the moving wheel 4 to ensure that the platform moves smoothly inside the tower and avoids deviation or swaying. III. Height Adjustment Mechanism

[0024] When work needs to be carried out at a higher position on the inner wall of the tower, the platform height is adjusted by hydraulic push rod 19. The operator directly issues a rising command on the controller 23, and the hydraulic system of hydraulic push rod 19 starts to work. Since the output end of hydraulic push rod 19 is fixedly connected to the bottom of support plate 2, it drives support plate 2 to move upward synchronously. During the rising process of support plate 2, the guide rod 21 fixed at its bottom slides in the guide cylinder 20 at the top of support frame 3. The cooperation between guide rod 21 and guide cylinder 20 effectively limits the radial displacement and rotation of support plate 2 during the rising process, ensuring that support plate 2 rises smoothly in the vertical direction and avoiding loss of balance of the operator due to swaying. When support plate 2 rises to a suitable height, hydraulic push rod 19 locks the current position through hydraulic locking system to maintain height stability and provide a reliable support platform for high-altitude operations. IV. Support Area Expansion

[0025] To meet the support area requirements of different work scenarios, the platform achieves flexible adjustment of the support area through expansion components. When it is necessary to expand the support area, the operator activates the electric push rod 16 on the controller 23. The electric push rod 16 is installed on the mounting plate at the bottom of the support plate 2 and is rotatably connected to the bottom end of the mounting plate through a rotating shaft. Its output end is hinged to the extension plate 6, forming a movable linkage mechanism. When the output end of the electric push rod 16 extends, it pushes the extension plate 6 to move horizontally outward through the hinge point. During the movement of the extension plate 6, the slide rod 18 fixed on its opposite side slides within the slide rail 17 fixed at the bottom of the support plate 2. The cooperation between the slide rail 17 and the slide rod 18 provides guidance and support for the movement of the extension plate 6, ensuring that the extension plate 6 expands smoothly and steadily, avoiding jamming or tilting. When the extension plate 6 expands to a suitable distance, the electric push rod 16 stops working. At this time, the extension plate 6 and the support plate 2 together form a larger working platform. Combined with the protective function of the guardrail 22, it provides a safer and more spacious working space for the operators.
