Description

Technical Field

[0001] This utility model relates to the research and application of installation and construction technology for new energy projects, and in particular to an anchor bolt concentricity detection device. Background Technology

[0002] In the installation of wind turbine generator sets, the accuracy of anchor bolt concentricity is crucial. Deviation in anchor bolt verticality will cause the concentricity of the anchor plate edge to exceed the standard, which will damage the sealing of the tower flange connection, cause uneven bolt preload, and make the unit prone to vibration due to stress imbalance during operation. Over time, this will lead to bolt fatigue fracture. Therefore, an anchor bolt concentricity detection device has emerged. By measuring, it ensures that the verticality and concentricity of the anchor bolts meet the specifications during installation, avoids structural safety hazards caused by installation errors from the source, and ensures stable operation of the unit.

[0003] The anchor bolt concentricity detection device constructs a spatial reference using laser beams. The transmitter emits multiple parallel laser beams at a fixed angle towards the anchor bolt, covering key sections such as the top and middle. After the beams are projected onto the anchor bolt surface, the reflection angle changes due to the axis offset, which is captured by a high-precision receiver. The module analyzes the positional deviation of the reflected beams at different sections, calculates the offset of each point by combining the principle of triangulation, and then reconstructs the actual axis through three-dimensional fitting. After comparing with the design reference, the concentricity deviation data is output in real time.

[0004] While current anchor bolt concentricity testing devices have driven advancements in industry testing technology, they suffer from limitations in portability. High-precision devices, to ensure measurement stability, employ a metal frame and multi-sensor integrated design, resulting in a large overall size and the need for external equipment. This makes them difficult to carry in complex working conditions, especially in large-scale projects with frequent site relocation. The inconvenience of carrying the equipment directly impacts construction progress and testing costs. Therefore, an anchor bolt concentricity testing device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anchor bolt concentricity testing device, which aims to improve the problem that the inconvenience of carrying the device in the prior art directly affects the construction progress and testing cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anchor bolt concentricity testing device includes a support column, a support plate rotatably connected to the outer wall of the support column, a limit plate fixedly connected to one side of the support plate, a second support plate fixedly connected to the outer wall of the support column, a limit plate fixedly connected to one side of the second support plate, a stud threaded to the inner wall of the support column, a rotating plate fixedly connected to one side of the stud, a reinforcing plate threaded to the other side of the stud, a limit block fixedly connected to one side of the second support plate, a connecting block slidably connected to the inner wall of the limit block, a positioning ring fixedly connected to the other side of the connecting block, a screw threaded to the inner wall of the connecting block, a fixing component fixedly connected to one side of the first support plate, a fixing block fixedly connected to one side of the fixing component, and a laser emission source fixedly connected to one side of the fixing block.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes two protrusions, the inner wall of which has a locking hole, the outer wall of which is slidably connected to an outer plate, the inner wall of which has a positioning hole, the inner wall of which is slidably connected to a fixing plate, the inner wall of which is threadedly connected to two screws, and the outer wall of each screw is slidably connected to a washer.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the second screw is threadedly connected to the inner wall of the limiting block, and a protective shell is fixedly connected to the top of the positioning ring.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the stud is threadedly connected to the inner wall of the first limiting plate, and the outer wall of the stud is threadedly connected to the inner wall of the second limiting plate.

[0014] As a further description of the above technical solution:

[0015] One side of the rotating plate is in contact with one side of the second limiting plate, and one side of the reinforcing plate is in contact with one side of the first limiting plate.

[0016] As a further description of the above technical solution:

[0017] A fixing block is fixedly connected to one side of the two outer plates that are close to each other, and the outer wall of the fixing plate is slidably connected to the outer wall of the two card holes;

[0021] One side of the gasket is in contact with one side of the fixing plate, and the other side of the gasket is in contact with one side of the support plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by rotating the rotating plate, the stud is rotated and unscrewed from the inner wall of the reinforcing plate, the limiting plate one, and the support column, thus releasing the restriction of the limiting plate two on the limiting plate one. This allows the support plate one to rotate relative to the support plate two on the outer wall of the support column. After the two sides are in contact, the rotating plate is rotated again to drive the stud to screw in in the opposite direction, allowing the limiting plate two to relock the limiting plate one. The reinforcing plate enhances the stability of the stud threaded connection, thereby strengthening the locking of the limiting plate two on the limiting plate one. This makes the device foldable and structurally robust, greatly improving portability and making it suitable for various complex construction scenarios.

[0024] 2. In this utility model, when in use, rotating screw two allows the positioning ring and support plate two to separate quickly. The protective shell can protect the precision components inside the positioning ring. Rotating screw one releases the support plate from locking the fixing plate, allowing the fixing plate to slide out from the positioning hole and the locking hole. The outer plate, along with the fixing block and the laser emission source, can then be removed from the surface of the support plate, improving the portability of the device. Installation is done by reversing the operation. The positioning hole and the fixing plate work together to allow the laser emission source to be accurately positioned, while the gasket enhances the screw fixing effect, making the device stable and durable.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an anchor bolt concentricity testing device, including a support column 1. The support column 1 serves as the core support structure of the entire testing device, providing a foundation for the installation and connection of other components and ensuring the overall stability of the device. A support plate 2 is rotatably connected to the outer wall of the support column 1. The support plate 2 can rotate around the support column 1, and the device can be folded and unfolded through rotation, making it easy to carry and use. A limit plate 3 is fixedly connected to one side of the support plate 2. A support plate 4 is fixedly connected to the outer wall of the support column 1, providing additional support for the device. A limit plate 5 is fixedly connected to one side of the support plate 4. The limit plate 5 works in conjunction with the limit plate 3 to control the folding and unfolding state of the device. A stud 7 is threadedly connected to the inner wall of the support column 1. The stud 7 is a key component for realizing the folding function of the device. By rotating, it changes its connection state with the limit plate 3 and the limit plate 5, thereby controlling the rotation of the support plate 2.

[0033] A rotating plate 6 is fixedly connected to one side of the stud 7. The rotating plate 6 facilitates the operator to apply force to rotate the stud 7, making the operation more convenient and efficient, and improving the user experience of the device. A reinforcing plate 8 is threadedly connected to the other side of the stud 7. The reinforcing plate 8 enhances the stability of the connection of the stud 7 and further ensures the locking effect of the second limiting plate 5 on the first limiting plate 3, so that the device remains firm after folding. A limiting block 18 is fixedly connected to one side of the second supporting plate 4. A connecting block 19 is slidably connected to the inner wall of the limiting block 18. The connecting block 19 can slide within the limiting block 18. The other side of the connecting block 19 is fixedly connected to... The device includes a positioning ring 20, which is used to position the anchor bolt and is one of the key components for detecting the concentricity of the anchor bolt. The inner wall of the connecting block 19 is threaded with screw 22, which is used to fix the connecting block 19 and the limiting block 18 to ensure that the positioning ring 20 is stable and does not loosen after installation. A fixing component is fixedly connected to one side of the support plate 2, a fixing block 13 is fixedly connected to one side of the fixing component, and a laser emission source 14 is fixedly connected to one side of the fixing block 13. The laser emission source 14 emits laser light to detect the concentricity of the anchor bolt and is the core component for the device to realize the detection function.

[0034] The fixing assembly includes two protrusions 9, with locking holes 10 on the inner walls of the protrusions 9. An outer plate 11 is slidably connected to the outer walls of the two protrusions 9, and the outer plate 11 can slide on the protrusions 9. A positioning hole 12 is provided on the inner wall of the outer plate 11, and a fixing plate 16 is slidably connected to the inner wall of the positioning hole 12. The fixing plate 16, through cooperation with other components, realizes the fixing and disassembly of the outer plate 11, thereby controlling the installation and disassembly of the laser emission source 14. Two screws 15 are threadedly connected to the inner wall of the fixing plate 16. The screws 15 are used to fix the fixing plate 16, ensuring that the outer plate 11 is firmly installed and that the laser emission source 14 will not shift during the detection process. Washers 17 are slidably connected to the outer walls of the two screws 15. The washers 17 enhance the fixing effect of the screws 15, prevent them from loosening, and further ensure the stability of the installation of the laser emission source 14.

[0035] Reference Figures 2 to 4The outer wall of screw 22 is threaded to the inner wall of the limiting block 18. This connection method ensures that the positioning ring 20 is firmly connected to the support plate 24 and remains stable during the testing process. The top of the positioning ring 20 is fixedly connected to a protective shell 21. The protective shell 21 provides protection for the precision positioning components inside the positioning ring 20, preventing them from being damaged by the outside world and extending the service life of the components. The outer wall of stud 7 is threaded to the inner wall of the limiting plate 3 and also threaded to the inner wall of the limiting plate 25, so that stud 7 can connect the limiting plate 3 and the limiting plate 25 to lock the support plate 2. One side of the rotating plate 6 is in contact with one side of the limiting plate 25, which makes it convenient for the operator to rotate the stud 7 by rotating the rotating plate 6, thereby controlling the folding and unfolding of the device. One side of the reinforcing plate 8 is in contact with one side of the limiting plate 3, which enhances the connection strength between stud 7 and the limiting plate 3 and the limiting plate 25, making the device more secure after folding.

[0036] A fixing block 13 is fixedly connected to one side of the two outer plates 11, ensuring that the fixing block 13 and the laser emission source 14 can be installed and removed together with the outer plates 11, facilitating the carrying and assembly of the device. The outer wall of the fixing plate 16 is slidably connected to the outer wall of the two locking holes 10. This connection method allows the fixing plate 16 to slide within the locking holes 10, realizing the fixing and unlocking of the outer plates 11. The outer wall of the screw 15 is threadedly connected to the inner wall of the support plate 2. By tightening or loosening the screw 15, the fixing plate 16 can be locked and unlocked, thereby controlling the disassembly and installation of the outer plates 11. One side of the connecting block 19 is in contact with one side of the support plate 2, ensuring that the connecting block 19 and the support plate 2 are tightly connected, making the positioning ring 20 stable and reliable after installation. One side of the gasket 17 is in contact with one side of the fixing plate 16, and the other side is in contact with one side of the support plate 2. When the screw 15 is tightened, the gasket 17 increases the friction to prevent the screw 15 from loosening, ensuring that the laser emission source 14 is installed firmly.

[0037] Working Principle: When the entire device needs to be moved during operation, rotating plate 6 causes the stud 7 to rotate, thereby causing the stud 7 to rotate out from the inner wall of reinforcing plate 8, limiting plate 3, and support column 1 in sequence. This releases the stud 7 from the restriction of limiting plate 3 by limiting plate 2, allowing support plate 2 to rotate relative to support plate 4 on the outer wall of support column 1 until one side of support plate 2 contacts one side of support plate 2. At this point, rotating plate 6 is rotated again to cause the stud 7 to rotate, thereby causing limiting plate 2 to relock limiting plate 3. Thanks to the presence of reinforcing plate 8, the threaded connection of stud 7 is more stable, further reinforcing the locking of limiting plate 2 to limiting plate 3. This allows the entire device to fold securely, greatly improving its portability. Rotating screw 22 allows positioning ring 2 to... The device can be quickly separated from the support plate 24. Thanks to the protective shell 21, the precision positioning components inside the positioning ring 20 are well protected. Rotating screw 15 releases the locking restriction of the support plate 2 on the fixing plate 16, allowing the fixing plate 16 to slide out from the inner wall of the positioning hole 12 and the snap hole 10. This initially releases the restriction of the support plate 2 on the outer plate 11, allowing the outer plate 11 to slide out from the inner wall of the protrusion 9. The outer plate 11, along with the fixing block 13 and the laser emission source 14, can be removed from the surface of the support plate 2, further improving the portability of the entire device. When installing, the disassembly steps can be reversed to complete the quick assembly. Thanks to the cooperation of the positioning hole 12 and the fixing plate 16, the laser emission source 14 can be positioned in the predetermined position each time it is assembled. Thanks to the presence of the washer 17, the fixing and locking of screw 15 is more secure.
