[0002] With the continuous growth of my country's national economy and the development of urban infrastructure construction, the construction of urban underground integrated utility tunnels has become a new trend in urban infrastructure construction and development. Especially with the gradual inclusion of high-voltage power lines and cables into integrated utility tunnels, power compartments and pipeline compartments need to be installed. Cables require support via cable brackets. Cable bracket construction often involves the installation of numerous embedded steel plates within the integrated utility tunnel structure. If these embedded steel plates are not installed correctly, it will affect the subsequent installation and stability of the brackets. Therefore, accurate positioning of the embedded steel plates is of paramount importance.

[0003] Currently, the installation of embedded steel plates mainly adopts welding, which involves directly welding the embedded steel plates to the main structural steel bars.

[0004] Existing methods for welding embedded steel plates often result in inadequate support of the embedded parts, affecting subsequent installation. Therefore, this invention proposes an installation and positioning device for embedded steel plates to solve the above problems. Utility Model Content

After the positioning frame 11 and the positioning plate 10 are engaged, the positioning frame 11 can connect the positioning plate 10 and the rotating rod 8 to block the rotation of the rotating rod 8 at the front side of the telescopic rod 9. This prevents the rotating rod 8 from rotating at the front side of the telescopic rod 9, thus preventing the control of the height of the top plate 4. This allows the positioning of the top plate 4 to be achieved, enabling the top plate 4 to stably position the embedded steel plate.

[0045] As a preferred embodiment of the present invention, the unlocking mechanism includes: a pull rod 14, a driving block 15, a sliding frame 16, and a control frame 17;

Sliding frame 16 is in slidable contact with driving block 15. Control frame 17 is in slidable contact with sliding frame 16. Control frame 17 is slidably connected to the top of sliding block 7 located at the lower position. After control frame 17 is pushed to the left, control frame 17 can push sliding frame 16 to slide on rotating rod 8 and fixed block 13, so that the movable driving block 15 of sliding frame 16 moves downward, so that driving block 15 can pull pull rod 14, so that pull rod 14 can pull positioning frame 11 to disengage from positioning plate 10, thereby unlocking rotating rod 8. When sliding block 7 at the lower position is pushed forward, sliding block 7 can push rotating rod 8 to rotate counterclockwise in front of telescopic rod 9, thereby lifting top plate 4 and pulling telescopic rod 9 upward, thus adjusting the height of top plate 4. Top plate 4 can support the pre-embedded steel plate to any height.

[0048] As a preferred embodiment of this utility model, horizontal sliding grooves are provided on the sides of the bottom and top plates 4 that are close to each other. Two sliding blocks 7 are slidably connected to the inner walls of the two horizontal sliding grooves respectively. The horizontal sliding grooves are used to install the sliding blocks 7, so that the sliding blocks 7 can stably lift the top plate 4.

[0049] As a preferred embodiment of this utility model, a matrix of limiting rods 3 are fixedly installed on the top of the base plate 1. There are four limiting rods 3, and the tops of the four limiting rods 3 are fixedly connected to the bottom of the top plate 4.

[0051] As a preferred embodiment of this utility model, four casters 2 are fixedly installed at the bottom of the base plate 1 in a matrix arrangement. The casters 2 have their own braking mechanism, similar to the braking mechanism on a stroller, which facilitates the movement of the base plate 1 and provides stable support for the base plate 1.

[0052] The working principle of this utility model is as follows: An embedded steel plate is placed on top of the top plate 4. Then, the threaded rod 5 drives the clamp 6 to descend, clamping the embedded steel plate. The sliding block 7 at the lower position is then unlocked. Simply push the control frame 17 to the left on the sliding block 7 at the lower position. After the control frame 17 is pushed to the left, it can push the sliding frame 16 to slide on the rotating rod 8 and the fixed block 13. This causes the movable driving block 15 of the sliding frame 16 to move downwards, allowing the driving block 15 to pull the pulling rod 14. The pulling rod 14 then pulls the positioning frame 11 away from the positioning plate 10, unlocking the rotating rod 8. When the sliding block 7 at the lower position is pushed forward, it can push the rotating rod 8 to rotate counterclockwise in front of the telescopic rod 9, thus unlocking the top plate. 4. By lifting and pulling the telescopic rod 9 upward, the height of the top plate 4 can be adjusted. The top plate 4 can support the embedded steel plate to any height, facilitating welding of the embedded steel plate. The position of the top plate 4 can also be positioned. Simply release the control frame 17, and the control frame 17 releases the positioning frame 11, so that the positioning frame 11 can automatically engage with the positioning plate 10. After the positioning frame 11 engages with the positioning plate 10, the positioning frame 11 can connect the positioning plate 10 with the rotating rod 8, thereby blocking the rotation of the rotating rod 8 on the front side of the telescopic rod 9. This prevents the rotating rod 8 from rotating on the front side of the telescopic rod 9, thus preventing the height of the top plate 4 from being controlled. This allows the top plate 4 to be positioned, stably supported, and stably welded to the embedded steel plate.
