Technical Field
[0001] This application relates to the field of bridge construction technology, specifically to a pre-embedded positioning device for bridge cable anchor cylinders. Background Technology
[0002] Currently, in the construction of large bridges, the anchoring of stay cables is one of the key aspects to ensure the safety and stability of the bridge structure. Traditional anchor pre-embedding methods mainly involve manual measurement and layout, manual adjustment, and fixing. While these methods are simple and easy to implement, they have significant limitations in terms of accuracy and efficiency. With the continuous expansion of bridge engineering scale and the increasing technical requirements, traditional manual pre-embedding methods can no longer meet the needs of modern bridge construction. Therefore, a bridge stay cable anchor pre-embedding positioning device is needed.
[0003] Regarding the aforementioned technologies, the applicant believes that when the positioning device is working, the support base is first moved to the location where the anchor tube is pre-embedded, and then the anchor tube can be fixed on the support base. The anchor tube is then fixed with fixing bolts, thereby enabling the pre-embedded positioning of the anchor tube. However, when the anchor tube is fixed on the support base, due to the influence of the anchor tube's own weight, the connection between the anchor tube and the support base is prone to deviation, causing the anchor tube installation position to be easily offset, thus leading to the problem of inaccurate anchor tube positioning. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solution: a pre-embedded positioning device for a bridge cable-stayed anchor cylinder, comprising a flange body and an adjustment mechanism. The adjustment mechanism is located at the bottom of the flange body and includes a fixed seat located at the top of the flange body. A threaded rod is threaded through the internal thread of the fixed seat. A snap-fit seat is provided at one end of the threaded rod near the center point inside the flange body, for the threaded rod to drive the snap-fit seat to move left and right. A snap-fit block is threaded through the top of the snap-fit seat, and the anchor cylinder body is located at the top of the snap-fit block. Threaded holes are evenly opened at both ends of the snap-fit seat, and locking bolts are threaded through the internal threads of the threaded holes.

[0008] By adopting the above technical solution, the support column can be conveniently used to support the flange body, effectively improving the stability of the flange body during operation.
[0009] Preferably, the bottom end of the support column is provided with a support base, and the support base is provided with fixing holes evenly distributed around its perimeter.
[0010] By adopting the above technical solution, the support base can be fixed by passing expansion bolts through the fixing holes.

[0012] By adopting the above technical solution, the threaded rod can be conveniently limited.
[0013] Preferably, the end of the threaded rod away from the locking seat is provided with a rotating handle, and the locking seat is provided with a U-shape.
[0014] By adopting the above technical solution, the threaded rod can be rotated by rotating the handle.
[0015] Preferably, the threaded rod has uniformly spaced limiting holes inside, which match the limiting pins.
[0016] By adopting the above technical solution, the limiting pin can be easily inserted into the limiting hole.
[0017] Preferably, the snap-fit block has uniformly spaced mounting holes inside, which engage with locking bolts.
[0018] By adopting the above technical solution, the pre-embedded position of the anchor cylinder body can be easily adjusted by inserting the locking bolt into the mounting holes at different positions.
[0019] Preferably, the limiting pin is L-shaped and passes through the interior of the limiting block and the limiting hole respectively.
[0020] By adopting the above technical solution, the threaded rod can be easily fixed by inserting the limiting pin through the limiting block into the limiting hole inside the threaded rod, thus avoiding movement of the threaded rod during operation and effectively improving the stability of the device during operation, thereby effectively improving the positioning accuracy of the anchor cylinder body.

Furthermore, the system includes a limit block, limit hole, and limit pin. Inserting the limit pin through the limit block into the limit hole inside the threaded rod further secures the rod, preventing movement and enhancing stability, thus improving the positioning accuracy of the anchor body.

Detailed Implementation
[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0030] Example 1
[0031] Please see Figures 1 to 4 This embodiment provides a technical solution: a pre-embedded positioning device for a bridge cable-stayed anchor cylinder, including a flange body 1 and an adjustment mechanism 5. The adjustment mechanism 5 is located at the bottom end of the flange body 1. The adjustment mechanism 5 includes a fixed seat 501 fixedly connected to the top end of the flange body 1. The fixed seat 501 is provided with a rectangular block. A threaded rod 503 passes through the internal thread of the fixed seat 501. A snap-fit seat 504 is rotatably connected to one end of the threaded rod 503 near the center point inside the flange body 1. The snap-fit seat 504 is U-shaped. A rotating handle 509 is fixedly connected to one end of the threaded rod 503 away from the snap-fit seat 504. By rotating the rotating handle 509, the threaded rod 503 can be rotated, which is used to move the snap-fit seat 504 left and right. A snap-fit block 506 is provided through the top end of the snap-fit seat 504. An anchor cylinder body 502 is fixedly connected to the top end of the snap-fit block 506. The snap-fit block 506 at the bottom end of the anchor cylinder body 502 is directly inserted into the anchor cylinder body 502. The anchor body 502 can be easily installed on the top of the flange body 1 by the snap-fit seat 504, which improves the installation speed of the anchor body 502. The anchor body 502 can be easily connected to the bridge cable stays. The snap-fit seat 504 has threaded holes 508 evenly distributed at both ends. The threads of the threaded holes 508 are threaded through the threaded holes 508 and the locking bolts 505 are engaged with the threaded holes 508. The snap-fit block 506 has mounting holes 507 evenly distributed inside. By inserting the locking bolts 505 into the mounting holes 507 at different positions, the pre-embedded position of the anchor body 502 can be easily adjusted. The mounting holes 507 are engaged with the locking bolts 505. By inserting the locking bolts 505 into the threaded holes 508 and the mounting holes 507, the anchor body 502 can be easily fixed. The anchor body 502 can be easily installed on the device, thereby effectively improving the positioning accuracy of the anchor body 502.
[0032] The overall effect of this embodiment is as follows: by rotating the handle 509, the threaded rod 503 can be moved, which in turn moves the locking seat 504, making it easy to adjust the position of the anchor body 502. Then, the locking block 506 at the bottom of the anchor body 502 can be directly inserted into the locking seat 504, and the locking bolt 505 can be inserted into the threaded hole 508 and the mounting hole 507, which makes it easy to fix the anchor body 502 and install it on the device, minimizing the risk of the anchor body 502 shifting during installation and effectively improving the stability of the anchor body 502 during installation.
[0033] Example 2
[0034] The bottom of the flange body 1 is uniformly fixedly connected with support columns 2. The support columns 2 are made of 60mm steel pipe, made of Q235 steel, and the surface is hot-dip galvanized to improve the corrosion resistance of the support columns 2 and effectively extend the service life of the support columns 2. There are four sets of support columns 2, which are symmetrically distributed about the internal center point of the flange body 1. This allows the support columns 2 to easily support the flange body 1 and effectively improve the stability of the flange body 1 during operation. The flange body 1 is made of cast iron and is welded to the support columns 2. The bottom of the support columns 2 is fixedly connected with a support base 4, which can provide load-bearing capacity. The support base 4 is uniformly provided with fixing holes 3 around its perimeter, which can facilitate the installation of the support base 4 on the ground.
[0035] The effect achieved by the entire second embodiment is as follows: the support base 4 is moved to the designated position, and the support base 4 can be fixed by passing the expansion bolts through the fixing hole 3. Then, the four support columns 2 are inserted into the reserved holes on the support base 4 and fixed with fixing bolts. Subsequently, the flange body 1 is installed on the support columns 2.
[0036] Example 3
[0037] A limiting block 510 is fixedly connected above the end of the fixed base 501 near the rotating handle 509. A limiting pin 512 is provided through the inside of the limiting block 510. The limiting pin 512 is L-shaped, which can facilitate the movement of the limiting pin 512 by the operator. Limiting holes 511 are evenly opened inside the threaded rod 503. The limiting holes 511 match the limiting pin 512, which can be easily inserted into the limiting hole 511. The limiting pin 512 passes through the inside of the limiting block 510 and the limiting hole 511 respectively.
[0038] The effect achieved by the entire embodiment 3 is as follows: when the card seat 504 is moved to the appropriate position, by inserting the limiting pin 512 through the limiting block 510 into the limiting hole 511 inside the threaded rod 503, the threaded rod 503 can be easily fixed, and the movement of the threaded rod 503 during operation can be avoided as much as possible, which effectively improves the stability of the device during operation, thereby effectively improving the positioning accuracy of the anchor body 502.
[0039] Working principle: First, move the support base 4 to the designated position and fix it by passing expansion bolts through the fixing holes 3. Then, insert the four support columns 2 into the reserved holes on the support base 4 and fix them with fixing bolts. Then, weld the flange body 1 to the support columns 2. Then, by rotating the handle 509, the threaded rod 503 can be moved, which can also move the snap-fit seat 504, which can facilitate the adjustment of the position of the anchor body 502. Then, the snap-fit block 506 at the bottom of the anchor body 502 can be directly inserted into the snap-fit seat 504. Then, the locking bolt 505 is inserted from the threaded hole 508 and the mounting hole 507, which can facilitate the fixing of the anchor body 502 and the installation of the anchor body 502 on the device. This avoids the anchor body 502 from shifting during installation and effectively improves the stability of the anchor body 502 during installation.
[0040] Secondly, after the locking seat 504 is moved to the appropriate position, the limiting pin 512 is inserted into the limiting hole 511 inside the threaded rod 503 through the limiting block 510, which can easily fix the threaded rod 503 and minimize the movement of the threaded rod 503 during operation, thereby effectively improving the stability of the device during operation and thus effectively improving the positioning accuracy of the anchor cylinder body 502.
