Description

Technical Field

[0001] This utility model provides a grouting device for the joints of wind turbine towers, belonging to the field of wind turbine tower production and processing technology. Background Technology

[0002] Wind turbine towers are crucial supporting structures for wind turbine generators, typically composed of multiple steel sections connected by flanges or sleeves, with lengths ranging from tens to hundreds of meters. During manufacturing and installation, welding or grouting is required at the circumferential joints between the sections to ensure the overall structural stability and sealing. Because wind turbine towers are subjected to wind loads, vibrations, and environmental corrosion over extended periods, the filling materials at the joints must possess high strength, weather resistance, and fatigue resistance. Traditional methods utilize high-strength grout or epoxy resin for sealing and reinforcement.

[0003] After applying grout to wind turbine towers, small-area repairs or localized grouting are often required. Due to the large-diameter, curved structure of the tower, it is difficult for workers to quickly move the grouting tools, significantly reducing grouting efficiency. Furthermore, when grouting multiple locations, traditional grout brushes are difficult to apply, often requiring the brush to be removed from the grouting location, dipped in fresh grout, and then moved back, severely impacting construction efficiency. After grouting, if accelerated curing is needed (e.g., in low-temperature environments or to meet deadlines), existing technologies lack efficient and uniform drying methods, making it impossible to simultaneously dry the entire joint, resulting in uneven curing speeds and affecting the overall strength and durability of the joint. Therefore, there is an urgent need for a wind turbine tower joint grouting device to solve the problems of positioning, application, and rapid drying in circumferential joint construction, improving the installation efficiency and reliability of wind turbine towers. Utility Model Content

[0004] The technical problem this invention aims to solve is that the workpiece being repaired is difficult to move quickly, and it is also inconvenient to quickly apply the grout to the brush, resulting in low grouting efficiency and difficulty in simultaneously drying the entire joint.

[0005] To solve the above problems, the proposed technical solution is as follows: a grouting device for wind turbine tower joints, including a support frame located inside the tower; a central cylinder is fixedly connected above the support frame, the axis of the central cylinder coincides with the axis of the tower, and a brushing component capable of circumferentially brushing the joints on the inner wall of the tower is rotatably arranged around the central axis of the central cylinder; a sliding groove is provided inside the support frame, and a storage box capable of supplying material to the brushing component is slidably arranged in the sliding groove; several drying holes are provided on the outer wall of the central cylinder to dry the circumferential joints after grouting, and a wind turbine communicating with the drying holes is provided inside the central cylinder.

[0006] As an improvement, the drying holes are evenly distributed circumferentially on the central cylinder.

[0007] As an improvement, the brushing assembly includes a support plate, a first electric telescopic rod, and a grouting brush; the support plate is rotatably arranged around the central axis of the central cylinder, and the first electric telescopic rod is fixedly arranged on the support plate; the grouting brush is fixedly connected to the working end of the first electric telescopic rod, and the grouting brush is arc-shaped corresponding to the inner wall of the tower cylinder, and the grouting brush is in contact with the inner wall of the joint of the tower cylinder.

[0008] As an improvement, a fixing plate is fixedly installed inside the central cylinder, and a rotating motor is installed on the fixing plate, with the working end of the rotating motor fixedly connected to the support plate.

[0009] As an improvement, a second electric telescopic rod is provided on the support frame, and the working end of the second electric telescopic rod is fixedly connected to the storage box.

[0010] As an improvement, the support frame is provided with a moving wheel with a locking function.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model, by setting a central cylinder concentric with the tower and a rotatable brush assembly, enables the grout brush to automatically brush along the circumferential joints of the tower's inner wall, and allows for rapid repositioning of the grout brush while ensuring accurate positioning after repositioning, avoiding the tediousness and inefficiency of manual operation. The material storage box within the support frame slides and supplies material via a groove, allowing the grout brush to simply rotate to the position of the storage box during operation, significantly reducing grout replenishment time and improving construction efficiency.

[0013] 2. The outer wall of the central cylinder is equipped with evenly distributed drying holes. Combined with a built-in fan, this allows for simultaneous air drying of the entire joint area immediately after grouting, solving the problem of uneven drying in traditional processes. This design is particularly suitable for low-temperature environments or construction scenarios with tight deadlines, accelerating grout curing, improving the early strength of the joints, and ensuring the structural stability of the wind turbine tower.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This utility model provides a grouting device for the joint of a wind turbine tower: including a support frame 3, with a movable wheel with locking function installed below the support frame 3, and the support frame 3 is located inside the tower 1; a central cylinder 2 is fixedly connected above the support frame 3, the axis of the central cylinder 2 coincides with the axis of the tower 1, and a brushing component is rotatably arranged around the central axis of the central cylinder 2 to brush the circumference of the joint on the inner wall of the tower 1.

[0021] like Figure 3 As shown, the coating assembly includes a support plate 6, a first electric telescopic rod 5, and a grouting brush 4. The support plate 6 is rotatably arranged around the central axis of the central cylinder 2, and the first electric telescopic rod 5 is fixedly mounted on the support plate 6. The grouting brush 4 is fixedly connected to the working end of the first electric telescopic rod 5. The grouting brush 4 is arc-shaped, corresponding to the inner wall of the tower cylinder 1, and the grouting brush 4 is in contact with the inner wall of the joint of the tower cylinder 1. Since the axis of the central cylinder 2 coincides with the axis of the tower cylinder 1, the entire coating assembly rotates around the center of the tower cylinder 1, which can play a positioning role. At the same time, the setting of the first electric telescopic rod 5 can not only control the contact between the grouting brush 4 and the inner wall of the tower cylinder 1, but also facilitate the docking and feeding with the subsequent storage box 8.

[0022] A fixing plate 10 is fixedly installed inside the central cylinder 2. A rotating motor 11 is installed on the fixing plate 10, and the working end of the rotating motor 11 is fixedly connected to the support plate 6. The rotating motor 11 can easily drive the support plate 6 to rotate, and the range of rotation of the support plate 6 is 360° reciprocating rotation, avoiding the tangling of the wiring of the first electric telescopic rod 5.

[0023] like Figure 4 As shown, a groove 7 is provided inside the support frame 3, and a storage box 8 for supplying material to the brush assembly is slidably disposed in the groove 7. The storage box 8 stores a high-viscosity slurry to prevent the slurry from dripping from the slurry brush 4 after application. A second electric telescopic rod 13 is provided on the support frame 3, and the working end of the second electric telescopic rod 13 is fixedly connected to the storage box 8. The second electric telescopic rod 13 can be used to easily control the sliding of the storage box 8, allowing it to be slid below the slurry brush 4 for easy application of material to the slurry brush 4.

[0024] like Figure 3As shown, the outer wall of the central cylinder 2 has several drying holes 9 for drying the circumferential joints after grouting, and a fan 12 connected to the drying holes 9 is installed inside the central cylinder 2. The drying holes 9 are evenly distributed circumferentially on the central cylinder 2, which can perform all-round and uniform drying of the joints after grouting or patching.

[0025] The principle of this utility model

[0026] When using this device, firstly, after the grouting is completed, push the device into the tower cylinder 1 using the movable wheels under the support frame 3, and adjust it to the joint position for grouting. Secure the device using the locking function of the movable wheels to ensure stability during construction. Then, fill the pre-prepared grout into the storage box 8, such as... Figure 2 , 3 The state shown. (As indicated) Figure 4 As shown, the rotating motor 11 on the fixed plate 10 is started, driving the support plate 6 and the brushing assembly to rotate around the axis of the central cylinder 2. After rotating the grouting brush 4 to the position to be grouted, the first electric telescopic rod 5 is activated to push the grouting brush 4 to fit tightly against the joint of the inner wall of the tower cylinder 1. The arc-shaped grouting brush 4 can perfectly adapt to the curved surface structure of the tower cylinder 1, enabling uniform and continuous automatic brushing operations. It is also very convenient to move the working position of the grouting brush 4. Simply activate the first electric telescopic rod 5 to prevent the grouting brush 4 from fitting against the inner wall of the tower cylinder 1; restart the rotating motor 11 to rotate the grouting brush 4 to another position to be grouted, and then use the first electric telescopic rod 5 to make the grouting brush 4 fit tightly against the joint of the inner wall of the tower cylinder 1 to apply the grout. When it is necessary to apply grout to the brush 4, first use the first electric telescopic rod 5 to retract the brush 4 and rotate the brush 4 to a position close to the storage box 8. Then, activate the second electric telescopic rod 13 to slide the storage box 8 to a position below the brush 4. Use the first electric telescopic rod 5 to insert the brush 4 into the storage box 8 and re-apply new grout.

[0027] After the grouting or patching work is completed, the device can be slightly moved so that the drying holes 9 align with the joint. Immediately start the fan 12 inside the central cylinder 2. The airflow generated by the fan 12 is blown towards the joint through the evenly distributed drying holes 9, achieving simultaneous air drying of the entire joint. This design is particularly suitable for low-temperature environments or construction scenarios requiring tight deadlines. It can significantly accelerate the grout curing process, improve the early strength of the joint, and ensure the structural stability of the wind turbine tower 1.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
