Description

Technical Field

[0001] This utility model relates to the field of anchor bolt installation technology, specifically to an installation tool for prestressed anchor bolt components in wind turbine foundation engineering. Background Technology

[0002] Prestressed anchor bolt assemblies for wind turbine foundations are crucial components ensuring the stable installation of wind turbines on the foundation. They primarily consist of anchor bolts, upper anchor plates, lower anchor plates, anchor nuts, and PE pipes. During construction, the anchor bolt positions are precisely determined and installed in the foundation according to design requirements. Then, prestressing equipment is used to apply pre-tightening force to the anchor bolts, creating tensile stress between the anchor bolts and the foundation, significantly improving the foundation's tensile strength. Its working principle utilizes prestressing to effectively resist the enormous horizontal loads and overturning moments generated by the wind turbine during operation, limiting foundation deformation, preventing stress concentration, and ensuring long-term stable operation of the wind turbine. This assembly is suitable for various wind power projects, including onshore and offshore wind farms. Different specifications and models can be selected according to different site and geological conditions, reducing the amount of steel reinforcement and concrete used, improving construction efficiency, and saving costs. It is widely used in the wind power industry.

[0003] Currently, anchor bolts need to be kept vertically stable during installation to facilitate subsequent concrete pouring. However, anchor bolt installation is generally done manually by binding or welding, which is not suitable for installing multiple anchor bolts and is time-consuming and labor-intensive. Therefore, a prestressed anchor bolt assembly installation tool for wind turbine foundation engineering is needed to solve the above problems. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a prestressed anchor bolt assembly installation tool for wind turbine foundation engineering, including a bracket 1. A side plate 101 is fixedly connected to the bottom side of the bracket 1. A ground nail 102 is installed between the top and bottom of the side plate 101, which facilitates the installation of the bracket 1 on the ground. Several insertion holes are opened at the top of the bracket 1. A magnet 105 is fixedly connected to the top of the bracket 1 at the position of each insertion hole. An anchor bolt 5 is inserted into the inside of each insertion hole. A nut 501 is threaded to the outer end of each anchor bolt 5. A straight groove 103 is opened at the right side of the bracket 1, and a straight groove 104 is opened at the left side of the bracket 1. A rotating assembly is provided inside the straight groove 103. Part 2, the side end of the bracket 1 is provided with a limiting component 3 for limiting the rotation of the rotating component 2, and the outer end of the rotating component 2 is provided with a clamping component 4 for fixing the anchor bolt 5. By threading the nut 501 to the outer end of the anchor bolt 5, the anchor bolt 5 is inserted into the insertion hole, so that the nut 501 can be magnetically attracted to the top of the magnet 105. At this time, the anchor bolt 5 can be initially vertically fixed. Then, the rotating component 2 drives the clamping component 4 to clamp and fix several anchor bolts 5 at the same time. The limiting component 3 can prevent the rotating component 2 from rotating back. At this time, the anchor bolt 5 can be kept in a vertical state, which is convenient for subsequent concrete pouring. No manual binding or welding operation is required, and it is suitable for installing multiple anchor bolts 5, saving time and effort.

[0017] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the rotating assembly 2 includes a bidirectional threaded rod 201, which is rotatably disposed between the outer end of the bracket 1 and the inner end of the straight groove 103. A knob 202 is fixedly connected to the side end of the bidirectional threaded rod 201, and a gear 203 is fixedly connected to the outer end of the knob 202. A guide rod 204 is fixedly connected between the inner ends of the straight groove 104. The clamping assembly 4 includes two clamping plates 401, both of which are threaded to the outer end of the bidirectional threaded rod 201. The side end of each clamping plate 401 is sleeved on the outer end of the guide rod 204. Each side end of each clamping plate 401 has several arc-shaped grooves 402. Each anchor bolt 5 is fixedly connected with an anti-slip pad 403. During implementation, rotating the knob 202 can drive the bidirectional threaded rod 201 to rotate. Due to the limiting of the guide rod 204, the two clamping plates 401 can be easily driven to approach each other at the outer end of the bidirectional threaded rod 201. At this time, the anti-slip pad 403 in each arc groove 402 can fit and clamp the outer end of each anchor bolt 5. When the knob 202 is not rotated, the two clamping plates 401 can be tightly clamped on the side end of the anchor bolt 5 to prevent the anchor bolt 5 from tilting. Therefore, it is easy to keep the anchor bolt 5 in a vertical state, which is convenient for subsequent concrete pouring. No manual binding or welding operation is required, and it is suitable for installing multiple anchor bolts 5, saving time and effort.

[0018] As one implementation method in this embodiment, such as Figure 3 As shown, the limiting component 3 includes a limiting plate 301, which is rotatably mounted on the side of the bracket 1. A mounting platform 302 is fixedly connected to the side of the limiting plate 301. A lever 303 is fixedly connected to the right side of the limiting plate 301. An extension plate 304 is fixedly connected to the side of the bracket 1. A spring 305 is fixedly connected between the bottom of the extension plate 304 and the top of the mounting platform 302. The lever 303 is inclined, with its bottom end located within a toothed groove. In practice, rotating the knob 202 drives the gear 203 and the bidirectional threaded rod 201 to rotate. When the gear 203 rotates counterclockwise, the teeth push against the limiting plate 301, causing it to rotate and move upwards. The mounting platform 302 then retracts against the spring 305. The knob 202 and the bidirectional threaded rod 201 can continue to rotate. Since the guide rod 204 limits the movement, it is easy to drive the two clamping plates 401 to approach each other at the outer end of the bidirectional threaded rod 201. When the knob 202 stops rotating, the two clamping plates 401 can be tightly clamped on the side end of the anchor bolt 5 to prevent the anchor bolt 5 from tilting. At this time, since the gear 203 stops rotating, the limiting plate 301 is limited in the tooth groove due to the spring 305. At this time, when the knob 202 is rotated without pressing the lever 303, the lever 303 will be limited in the tooth groove, so that the knob 202 and the bidirectional threaded rod 201 cannot rotate back. Therefore, the clamping plate 401 can be stably clamped on the side end of the anchor bolt 5.

[0019] Working principle: By threading the nut 501 onto the outer end of the anchor bolt 5, the anchor bolt 5 is inserted into the insertion hole, allowing the nut 501 to be magnetically attracted to the top of the magnet 105, thus initially fixing the anchor bolt 5 vertically. Next, rotating the knob 202 drives the gear 203 and the double-threaded rod 201 to rotate. When the gear 203 rotates counterclockwise, its teeth push against the limiting plate 301 and move upwards, causing the mounting platform 302 to retract against the spring 305. The knob 202 and the double-threaded rod 201 can continue to rotate. Due to the limiting effect of the guide rod 204, the two clamping plates 401 can easily move closer together at the outer end of the double-threaded rod 201. At this time, the anti-slip pads 403 in each arc groove 402 can adhere and clamp onto each... When the knob 202 stops rotating, the two clamping plates 401 can tightly clamp the side end of the anchor bolt 5, preventing the anchor bolt 5 from tilting. At this time, since the gear 203 stops rotating, the limiting plate 301 is limited in the tooth groove due to the spring 305. When the knob 202 is rotated clockwise without pressing the lever 303, the lever 303 will be limited in the tooth groove, preventing the knob 202 and the bidirectional threaded rod 201 from rotating back. Therefore, the clamping plate 401 can be stably clamped on the side end of the anchor bolt 5, which makes it easy for the anchor bolt 5 to maintain a vertical state, which is convenient for subsequent concrete pouring. No manual binding or welding is required, and it is suitable for installing multiple anchor bolts 5, saving time and effort.

[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
