Detailed implementation manners
[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] In one embodiment, as Figures 1-5 shown, a temporary plugging device for the core of a pipe pile includes a plugging plate 11. A positioning ring groove 13 and a top groove 19 are opened at the upper end of the plugging plate 11, and the positioning ring groove 13 is located outside the top groove 19;
[0031] A rotating cavity 21 is opened inside the plugging plate 11. Four guiding sliding openings 20 are equally angularly opened at the bottom end of the plugging plate 11. A through hole is opened at the inner bottom of the top groove 19, and the top groove 19, the guiding sliding openings 20 and the inside of the rotating cavity 21 are connected and communicated;
[0032] It further includes an adaptation structure which is arranged inside the rotating cavity 21 and is used to adapt to core openings of different sizes.
[0033] In this embodiment, first, the plugging plate 11 is placed above the core opening to be plugged, ensuring that the plugging plate 11 is roughly aligned with the core opening. When facing core openings of different sizes, the user can achieve precise adaptation to the core opening by operating the adaptation structure.
[0034] In one embodiment, as Figures 4-5As shown, the adaptation structure includes a rotating square plate 22, which is installed inside a rotating cavity 21. At the bottom corner of the rotating square plate 22, an arc-shaped strip plate 25 is rotatably installed through a rotating shaft. The other end of the arc-shaped strip plate 25 is rotatably connected to a sliding block 26 through a rotating shaft. The sliding block 26 is slidably installed inside a guiding sliding opening 20. The bottom end of the sliding block 26 extends to the bottom end of a sealing plate 11 and is fixedly connected to a movable column 27. A rotating component is installed at the upper end of the rotating square plate 22.
[0035] The user can rotate the rotating square plate 22 by using the rotating component, which can drive the arc-shaped strip plate 25 at its bottom end to perform corresponding movements. The design of the arc-shaped strip plate 25 enables it to move along its arc trajectory during rotation, thereby pushing the connected sliding block 26 to slide inside the guiding sliding opening 20. Thus, the position of the movable column 27 can be adjusted to make it closely fit the inner wall of the pile core opening, achieving effective sealing. This design allows the adaptation structure to be flexibly adjusted according to the actual size of the pile core opening.
[0036] In one embodiment, as Figures 4-5 shown, the rotating component includes a connecting column 23, which is fixedly installed at the middle position of the upper end of the rotating square plate 22. The upper end of the connecting column 23 passes through a through hole and extends into a top groove 19 and is fixedly connected to a rotating handle 24.
[0037] The user can rotate the square plate 22 through the rotating handle 24, thereby driving the subsequent components to operate, and further adjusting the position of the movable column 27, ultimately ensuring that the device can adapt to pile core openings of different sizes.
[0038] In one embodiment, as Figure 3 shown, a cover plate 15 is installed at the upper end of the sealing plate 11, and a plurality of fixing holes 16 are formed through the upper end of the cover plate 15.
[0039] The cover plate 15 directly covers the upper part of the sealing plate 11, forming a protective layer, which can effectively prevent direct damage to the sealing plate 11 by external factors, such as wind, rain, and accidental collisions during construction, thereby extending the service life of the sealing plate 11.
[0040] In one embodiment, as Figure 3 shown, a positioning ring plate 17 that matches the positioning ring groove 13 is fixedly installed at the bottom end of the cover plate 15.
[0041] The design of the positioning ring plate 17 enables it to accurately fit into the positioning ring groove 13 on the sealing plate 11, thereby achieving precise positioning between the cover plate 15 and the sealing plate 11.
[0042] In one embodiment, as Figures 1-5As shown, an outer ring 12 is fixedly installed at the bottom of the outer side wall of the plugging plate 11. A plurality of fixing columns 14 are fixedly installed at the upper end of the outer ring 12. A threaded hole is formed at the upper end of the fixing column 14, and a bolt 18 is threadedly connected inside the threaded hole. The threaded hole corresponds to the fixing hole 16.
[0043] The threaded hole at the upper end of the fixing column 14 corresponds to the fixing hole 16 at the upper end of the cover plate 15. Through the threaded connection of the bolt 18, the precise fixation between the cover plate 15 and the plugging plate 11 can be achieved. This fixing method is not only simple to operate, but also has a reliable fixing effect, and can ensure that the plugging device always maintains a stable structural state during use.
[0044] In one embodiment, as Figures 1-5 shown, a rubber soft pad is installed at one end of the movable column 27 in contact with the pile core.
[0045] The soft material of the rubber soft pad can reduce the friction and impact on the inner wall of the pile core, and avoid scratching or damaging the pile core due to the hard contact of the movable column 27 during the plugging process. This is of great significance for protecting the integrity of the pile core and extending its service life.
[0046] In one embodiment, as Figures 1-5 shown, anti-slip lines are provided on the surface of the rubber soft pad.
[0047] The design of the anti-slip lines can increase the contact area between the rubber soft pad and the inner wall of the pile core, and generate greater friction through the concave-convex structure of the lines. This enhanced friction helps to prevent the plugging device from sliding or falling off under the action of external forces, and improves the stability and reliability of the plugging.
[0048] The above embodiment discloses a temporary plugging device for the pile core of a pipe pile. First, the plugging plate 11 is placed above the pile core opening to be plugged, and it is ensured that the plugging plate 11 is roughly aligned with the pile core opening. When the user needs to plug pile cores of different sizes, the rotating handle 24 can be rotated to drive the rotating square plate 22 to rotate in the rotating cavity 21. Due to the rotational connection relationship between the arc-shaped strip 25 and the sliding block 26, and the sliding restriction of the sliding block 26 in the guiding sliding opening 20, the rotation of the rotating square plate 22 will drive the movable column 27 to move outward or inward, thereby changing the position of the movable column 27 to adapt to pile core openings of different sizes. After installing the adaptation structure, the cover plate 15 is then fixed to the plugging plate 11 through the bolt 18 to complete the assembly and installation of the plugging device.
[0049] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
