[0002] As a crucial piece of clean energy equipment, the installation stability of wind turbine generators directly impacts the long-term safety and reliability of their operation. During the overall installation of a wind turbine, the anchor bolt assembly plays a vital role in firmly connecting the tower base to the ground foundation.

Bolts and nuts are used to lock and secure the anchor bolts and anchor plates, forming an integral structure with sufficient prestress.

[0003] Currently, the industry generally adopts the following steps for assembling this assembly: First, the upper anchor plate is lifted and suspended in the air using hoisting equipment, while the lower anchor plate is pre-placed on the installation base on the ground, keeping them vertically aligned. Then, workers manually insert each anchor bolt into the corresponding installation holes of the two anchor plates from above, relying on the cooperation between ground personnel and workers on the upper anchor plate to ensure that the anchor bolts are roughly in place. After all the anchor bolts are placed, the nuts at both ends of each anchor bolt are tightened manually to complete the assembly and locking of the entire assembly.

[0004] However, the aforementioned traditional installation methods have the following significant drawbacks in practical engineering applications: the installation process requires multiple workers to operate on the suspended upper anchor plate, resulting in a complex high-altitude working environment that is prone to safety accidents such as falls and falling objects.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 6 As shown in the figure, a prestressed anchor bolt installation structure according to an embodiment of the present invention includes: An anchoring device, comprising an upper anchor plate 4, a lower anchor plate 4, and anchor bolt bodies 5 uniformly installed circumferentially between the two; The mounting platform assembly is used to limit and support the upper anchor plate 4 and the lower anchor plate 4 so that the anchor bolt body 5 can be installed between them; the mounting platform assembly includes a base plate 1, and side plates 2 are symmetrically arranged on both sides of the top of the base plate 1. A pair of support rollers 3 are arranged in parallel between the two side plates 2. Support wheels 19 for engaging the anchor plates 4 are respectively provided at both ends of the two support rollers 3; connecting rods 9 are respectively provided at both ends of the support rollers 3, and the connecting rods 9 are movably arranged in the movable grooves 12 provided on the side plates 2; The transmission components are located at both ends of the support roller 3 and are used to drive the two support rollers 3 to rotate.

[0024] During operation, the upper anchor plate 4 and lower anchor plate 4 are placed in the slots of the support rollers 19 on both sides, respectively. The distance between the two support rollers 3 is adjusted using the adjusting component to ensure that the upper anchor plate 4 and lower anchor plate 4 are securely engaged with the support rollers 19. Subsequently, the support rollers 3 are driven to rotate intermittently through the transmission component, which in turn drives the upper anchor plate 4 and lower anchor plate 4 to rotate synchronously by the support rollers 19. As the support rollers 3 rotate intermittently, the upper anchor plate 4 and lower anchor plate 4 also rotate intermittently to continuously install the anchor bolt body 5 until the assembly of the entire anchoring device is completed.

[0025] Throughout the installation process, the anchoring device operates horizontally on the ground, eliminating the need for high-altitude work, which greatly reduces installation difficulty and safety risks. Simultaneously, the intermittent rotation design of the support roller 3 allows each anchor body 5 to be precisely installed while stationary, effectively improving installation quality and efficiency.

[0026] The transmission assembly includes: A transmission rod 10 is positioned below the middle of the two support rollers 3 and is arranged along the length of the support rollers 3. Transmission shafts 14 are respectively provided at both ends of the transmission rod 10. A motor 13 is connected to one side of the transmission shaft 14, and the motor 13 is slidably connected to the adjacent side plate 2. A slide is rotatably connected to the other side of the transmission shaft 14, and the slide is slidably connected to the adjacent side plate 2. A sprocket 15 is fixed to each of the two transmission shafts 14. A second sprocket 18 is fixed to the connecting rod 9 at the ends of the two support rollers 3 respectively; a transmission chain 17 is sleeved on the first sprocket 15 and the second sprocket 18 on the same side.

[0027] When in operation, the motor 13 is started, and the motor 13 drives the transmission shaft 14 connected to it to rotate. The sprocket 15 on the transmission shaft 14 rotates accordingly, and the power is transmitted to the sprocket 18 on the connecting rod 9 at the end of the support roller 3 on the same side through the transmission chain 17, thereby driving the support roller 3 to rotate.

[0028] It also includes an adjustment component, symmetrically arranged at both ends of the support roller 3, for adjusting the distance between the two support rollers 3; the adjustment component includes an internally threaded sleeve 23 fixed to the connecting rods 9 on both sides, a hexagonal sleeve rod 26 is provided in the middle of the internally threaded sleeves 23 on both sides, and threaded rods 24 are fixed at both ends of the hexagonal sleeve rod 26 respectively, and the threaded rods 24 on both sides are respectively connected to the inside of the internally threaded sleeves 23 on the adjacent sides; a sprocket 3 25 is fixed on the hexagonal sleeve rod 26 on both sides, and the sprocket 3 25 on both sides are connected by a transmission chain 27.

[0029] During operation, the hexagonal sleeve 26 is rotated using a tool. The threaded rods 24 at both ends of the hexagonal sleeve 26 rotate within the internal threaded sleeves 23. Since the internal threaded sleeves 23 on both sides are relatively fixed to the connecting rod 9, as the hexagonal sleeve 26 rotates, the internal threaded sleeves 23 on both sides will move closer or further apart, thereby causing the distance between the two support rollers 3 to change, adapting to the installation requirements of upper and lower anchor plates 4 of different sizes. When the appropriate distance is adjusted, the rotation of the hexagonal sleeve 26 is stopped. At this time, the distance between the two support rollers 3 is fixed, and subsequent anchor bolt installation operations can be carried out. Furthermore, through the cooperation of sprocket 3 25 and transmission chain 2 27, rotating only one side of the hexagonal sleeve 26 can synchronously drive the rotation of the other side of the hexagonal sleeve 26, realizing the synchronous adjustment of the distance between the two support rollers 3. This makes the operation more convenient and ensures the consistency of the adjustment distance of the two support rollers 3, ensuring the stability and accuracy of the installation of the upper and lower anchor plates 4.

[0030] The connecting rods 9 at the ends of the two support rollers 3 are rotatably connected to the transmission shaft 14 on the same side via movable rods 16.

[0031] During operation, when the distance between the two support rollers 3 increases or decreases, the drive shaft 14 on the same side is driven to move via the movable rod 16. Due to the sliding connection structure between the slide table or motor 13 and the side plate 2, the drive shaft 14 can only move in the vertical direction without affecting its normal rotational function. In this way, the transmission chain 17 between sprocket 15 and sprocket 18 is always taut and will not come loose, ensuring that the transmission assembly can operate stably and reliably to continuously provide power for the rotation of the support rollers 3.

[0032] A vertical groove is provided in the middle of the top of the side plate 2. A movable plate 21 is slidably provided in the middle of the vertical groove. A lead screw 22 is rotatably installed in the middle of the vertical groove. The lead screw 22 is threadedly connected to a threaded hole in the middle of the movable plate 21. A pressure rod 20 is horizontally installed on the movable plate 21. The pressure rod 20 is slidably provided in a sliding hole on the movable plate 21.

[0033] During operation, the pressure rod 20 is pushed and pulled to move laterally along the sliding hole, thereby adjusting the positional relationship between the pressure rod 20 and the anchor plate 4. After the anchor plate 4 is installed in the slot of the support wheel 19, the pressure rod 20 is pushed to move towards the center, so that the pressure rod 20 moves to the area above the anchor plate 4. Then, the screw 22 is rotated. Since the screw 22 is threadedly connected to the threaded hole in the middle of the movable plate 21, the movable plate 21 will move downward along the vertical groove under the limiting action of the vertical groove, thereby driving the pressure rod 20 to move downward, so that the pressure rod 20 is pressed tightly against the inner ring side wall of the upper anchor plate 4 and the lower anchor plate 4, which further fixes the upper anchor plate 4 and the lower anchor plate 4, preventing the upper anchor plate 4 and the lower anchor plate 4 from shaking or shifting during the intermittent rotation of the upper anchor plate 4 and the lower anchor plate 4 driven by the support roller 3 to install the anchor bolt body 5, thus ensuring the stability and accuracy of the installation. Furthermore, the pressure rod 20 can rotate in the sliding hole and can rotate together with the anchor plate 4. The normal rotation of the anchor plate 4 will not be affected by the obstruction of the pressure rod 20, thus ensuring the continuity and smoothness of the installation process.

[0034] A U-shaped plate 33 is fixed on the side wall of the movable plate 21 facing the anchoring device. Movable frames 35 are symmetrically arranged on the upper and lower sides of the U-shaped plate 33. A spring 34 is arranged between the movable frame 35 and the side wall of the U-shaped plate 33. Rollers 36 are respectively arranged on the opposite side walls of the movable frames 35 on both sides. A turntable 37 is rotatably installed in the middle of the U-shaped plate 33. The edge of the turntable 37 is symmetrically arranged with grooves 38. Top rods 39 are respectively fixed on the opposite side walls of the movable frames 35 on both sides. The top rods 39 correspond to the grooves 38.

[0035] During operation, the spring 34 pushes the movable frame 35 and roller 36 to move, causing the roller 36 to press tightly against the side wall of the pressure rod 20. Since the roller 36 and pressure rod 20 rotate in the same direction, as the pressure rod 20 rotates with the anchor plate 4, the roller 36 rolls along the side wall of the pressure rod 20 without interfering with its rotation. Furthermore, the clamping of the pressure rod 20 by the rollers 36 on both sides makes it more stable and prevents wobbling during rotation. When the length of the pressure rod 20 needs to be adjusted, rotating the turntable 37 moves the end of the top rod 39 out of the groove 38, thus pushing the movable frame 35 and roller 36 away from the pressure rod 20. At this time, the spring 34 is compressed, and the pressure rod 20, no longer clamped by the roller 36, can slide smoothly in the sliding hole, achieving length adjustment. After adjusting to the appropriate length, rotate the turntable 37 in the opposite direction to allow the end of the top rod 39 to re-engage in the groove 38. Under the reset action of the spring 34, the movable frame 35 drives the roller 36 to press tightly against the side wall of the pressure rod 20 again, restoring the stable clamping state of the pressure rod 20 and ensuring that the pressure rod 20 can function stably during subsequent installation.

[0036] In addition, the roller 36 is made of rubber or silicone, which can increase the friction between it and the pressure rod 20 and prevent the pressure rod 20 from sliding laterally outward.

[0037] The support wheel 19 is sleeved on the support roller 3. A connecting ring 28 is fixed to the side wall of the support wheel 19. The connecting ring 28 is provided with a first mounting hole. The side wall of the support roller 3 is provided with a second mounting hole. The first mounting hole and the second mounting hole are fixedly connected by bolts.

[0038] During operation, after fitting the support wheel 19 onto the corresponding position on the support roller 3, align the mounting hole one on the connecting ring 28 with the mounting hole two on the side wall of the support roller 3, then insert and tighten the bolts. This securely fixes the support wheel 19 onto the support roller 3. This fixing method not only facilitates installation and disassembly, making subsequent maintenance and replacement of the support wheel 19 easier, but also allows adjustment of the distance between the two support wheels 19 to accommodate the installation requirements of upper and lower anchor plates 4 of different sizes, further enhancing the versatility and flexibility of this prestressed anchor bolt installation structure.

[0039] The support roller 3 has slots 29 at the middle of both ends, and the connecting rod 9 has a hexagonal plug 30 at its end, which is inserted into the slot 29. The transmission rod 10 has a sliding cavity 32 inside, and the transmission shaft 14 has a sliding rod 31 at its end, which is slidably disposed in the sliding cavity 32. The base plate 1 has hydraulic cylinders 11 fixed at both ends for driving the side plate 2 to move laterally.

[0040] During operation, the combination of hexagonal plug 30 and slot 29, slide rod 31 and sliding cavity 32 ensures a more stable and flexible connection between connecting rod 9 and support roller 3, and between drive shaft 14 and drive rod 10. When support wheel 19 wears down due to prolonged use and needs replacement, the hydraulic cylinder 11 is activated, driving side plate 2 to move outward. This drives drive shaft 14 and connecting rod 9. Because the length of slide rod 31 is greater than the length of plug, when plug detaches from slot 29, slide rod 31 always slides within sliding cavity 32, ensuring that drive shaft 14 and drive rod 10 do not separate. At this time, the worn support wheel 19 can be removed from the end of support roller 3, replaced with a new support wheel 19, and the hydraulic cylinder 11 is activated again, driving side plate 2 to move inward, allowing hexagonal plug 30 to re-insert into slot 29, achieving a stable connection between connecting rod 9 and support roller 3. The entire replacement process is simple to operate, requiring no complicated disassembly and installation steps, greatly improving maintenance efficiency.

[0041] Example 2: Figure 1As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a support platform 6 is fixed in the middle of the base plate 1, the support platform 6 is located below the support roller 3, a limiting plate 7 is fixed on the top of the support platform 6, an annular limiting groove 8 is opened in the middle of the support roller 3, and the limiting plate 7 is movably engaged in the limiting groove 8.

[0042] During operation, the support roller 3 is supported by the support platform 6, and the limiting plate 7 is engaged in the annular limiting groove 8 in the middle of the support roller 3, which restricts the horizontal movement of the support roller 3. During the replacement of the support wheel 19, the support roller 3 will not shift horizontally due to the movement of the side plate 2, and will always remain in the correct position, ensuring the stability of the entire installation structure. Furthermore, this limiting method does not affect the normal rotation of the support roller 3. Driven by the transmission component, the support roller 3 can still rotate smoothly intermittently, driving the upper anchor plate 4 and lower anchor plate 4 to rotate synchronously, thereby achieving continuous installation of the anchor bolt body 5. At the same time, the cooperation between the limiting plate 7 and the annular limiting groove 8 can also share the pressure borne by the support roller 3 to a certain extent, reducing the deformation of the support roller 3 caused by long-term stress, extending the service life of the support roller 3, and reducing the maintenance cost of the equipment.

[0043] like Figure 7 As shown, the present invention provides a method for installing prestressed anchor bolts, applicable to the aforementioned prestressed anchor bolt installation structure, comprising the following steps: S1. Install the upper anchor plate 4 and the lower anchor plate 4 into the slots of the two side support wheels 19 respectively; S2. Adjust the position of the pressure rod 20, and then rotate the screw 22 to drive the movable plate 21 and the pressure rod 20 to move downward, so that the pressure rod 20 presses tightly against the inner ring side wall of the upper anchor plate 4 and the lower anchor plate 4. S3. Install a pair of anchor bolt bodies 5 at corresponding positions on the upper anchor plate 4 and the lower anchor plate 4; S4. The support roller 3 is driven to rotate intermittently by means of the transmission component, which in turn drives the upper anchor plate 4 and the lower anchor plate 4 to rotate intermittently, so as to continuously install the anchor bolt body until the assembly of the anchoring device is completed.
