Description

Technical Field

[0001] This utility model belongs to the technical field of grouting nozzle structure, and in particular relates to a grouting nozzle structure for grouting to plug water in tunnels. Background Technology

[0002] Water inrush is a common geological hazard during tunnel construction, especially when crossing water-rich faults, fracture zones, or highly permeable rock layers. High-pressure water flow can rush into the working face through cracks and pores, which not only affects the construction progress but may also cause safety accidents such as collapse and piping. Therefore, grouting technology is needed to inject grout into the water inrush channel to form a seepage prevention curtain. As a key component connecting the grouting equipment and the tunnel rock mass, the performance of the grouting nozzle directly determines the water blocking effect.

[0003] However, the existing grouting nozzle structures have fixed sealing strength settings or can only be adjusted roughly during use, making it difficult to accurately adapt to the actual size of the injection port or working conditions. If the sealing strength is insufficient, gaps may appear due to pressure fluctuations, leading to grout leakage, which not only wastes materials but may also pollute the construction environment. Utility Model Content

[0004] The purpose of this utility model is to provide a grouting nozzle structure for grouting to plug water in tunnels. By setting a fixing part, it solves the problem that the sealing force is mostly fixed or can only be adjusted in a rough way, making it difficult to accurately adapt to the actual size of the injection port or working conditions. If the sealing force is insufficient, gaps are easily formed due to pressure fluctuations, resulting in grout leakage, which not only wastes materials but may also pollute the construction environment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a grouting nozzle structure for grouting and plugging water in tunnels, comprising an injection-molded pipe, and further comprising: a fixing part, the fixing part being installed on the injection-molded pipe; an anti-detachment part, the anti-detachment part being disposed on the injection-molded pipe; the fixing part comprising a sealing component, the sealing component being installed on the injection-molded pipe; and an inner support component, the inner support component being disposed on the sealing component; the sealing component comprising a turntable rotatably connected to the outer wall of the injection-molded pipe, the outer wall of the injection-molded pipe being fixedly connected to the fixing plate, the fixing plate being in contact with the turntable, the turntable having a plurality of limiting holes, and the injection-molded pipe being provided with a sealing element; wherein, four limiting holes are provided and arranged in a circumferential array, and the sealing element comprising a sealing plate fixedly connected to the rear side of the turntable; wherein, the sealing plate is provided with a sealing gasket.

[0007] Furthermore, the anti-detachment part includes a rotating assembly mounted on the injection molding tube; and a limiting assembly disposed on the rotating assembly; wherein the limiting assembly is located inside the rotating assembly.

[0008] Furthermore, the inner support assembly includes a T-shaped slide rod fixedly connected to the rear side of the fixed disk, a slider slidably connected to the T-shaped slide rod, and a transmission component 1 provided on the turntable; wherein, the slider is slidably connected to the T-shaped slide rod through a T-shaped groove, and the transmission component 1 includes a vortex groove fixedly connected to the turntable, and the slider engages with the vortex groove.

[0009] Furthermore, the rotating assembly includes a connecting ring disposed on the rear side of the turntable, a toothed ring 1 fixedly connected to the rear side of the connecting ring, and a transmission component 2 disposed on the outer wall of the toothed ring 1; wherein, the toothed ring 1 is provided with tooth blocks arranged in a circumferential array, and the transmission component 2 includes a handle fixedly connected to the outer wall of the toothed ring 1; wherein, the handle is provided with an anti-slip pad.

[0010] Furthermore, the limiting component includes a rotating ring rotatably connected to the inner wall of the first toothed ring, and a second toothed ring fixedly connected to the outer wall of the injection molding tube. The second toothed ring meshes with the first toothed ring, and a spring is provided inside the second toothed ring. The front side of the spring is fixedly connected to the rotating ring, and the rear side of the spring is fixedly connected to the second toothed ring; wherein the spring is in a stretched state.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a fixed part, the rotation of the handle is used as the power input, and the torque is transmitted to the turntable through the connecting ring, so that the turntable rotates synchronously; when the turntable rotates, the vortex groove on the inner wall of the turntable generates radial thrust on the slider using its curved trajectory, forcing several sliders to move away from each other along the guiding action of the T-shaped slide bar; during the movement, the slider extends out from the limiting hole and finally comes into close contact with the inner wall of the injection port. With the help of the friction between the slider and the inner wall of the injection port and the constraint of the limiting hole on the slider, the sealing plate is fixed, thereby achieving a seal. This avoids leakage caused by being too loose and prevents damage to the components caused by being too tight, and is suitable for injection ports of different sizes or working conditions.

[0013] 2. By setting an anti-detachment part, first insert the turntable into the injection port until the sealing plate contacts the wall to complete the initial positioning; when pushing the handle forward, the toothed ring one moves synchronously with it, driving the rotating ring to stretch the spring. When the toothed ring one and the toothed ring two disengage, the restriction on the rotation of the handle is released, and the handle can be rotated freely to perform the sealing operation; after sealing is completed, release the pushing force on the handle, and the spring's rebound force pulls the rotating ring back to its original position. The toothed ring one and the handle then retract, and finally the toothed ring one and the toothed ring two re-engage, locking the rotation of the toothed ring one again, avoiding accidental contact that could cause the seal to loosen or the parts to shift. During operation, simply push the handle to unlock, and after the operation is completed, the spring will automatically drive the lock, reducing the risk of forgetting the locking step.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The sealing assembly 21 includes a turntable 211 rotatably connected to the outer wall of the injection molding tube 111, and a fixing plate 212 fixedly connected to the outer wall of the injection molding tube 111. The fixing plate 212 contacts the turntable 211. The turntable 211 has several limiting holes 213. A sealing element is provided on the injection molding tube 111. Among them, four limiting holes 213 are provided and are distributed in a circumferential array. The inner support assembly 22 includes a component fixedly connected to the fixing plate 212. The T-shaped slide bar 221 on the side has a slider 222 slidably connected to it, and a transmission component is provided on the turntable 211. The slider 222 is slidably connected to the T-shaped slide bar 221 through a T-shaped groove. The sealing component includes a sealing plate 214 fixedly connected to the rear side of the turntable 211. A sealing gasket is provided on the sealing plate 214. The transmission component includes a vortex groove 223 fixedly connected to the turntable 211. The slider 222 engages with the vortex groove 223. By setting the fixing part 2, leakage caused by excessive looseness is avoided, and damage to the components caused by excessive tightness is prevented. It is suitable for injection ports of different sizes or working conditions.

[0026] The anti-detachment part 3 includes a rotating assembly 31, which is mounted on the injection molding tube 111; and a limiting assembly 32, which is disposed on the rotating assembly 31. The limiting assembly 32 is located inside the rotating assembly 31. The rotating assembly 31 includes a connecting ring 311 disposed on the rear side of the turntable 211, and a toothed ring 312 is fixedly connected to the rear side of the connecting ring 311. A transmission component 2 is disposed on the outer wall of the toothed ring 312. The toothed ring 312 has toothed blocks arranged in a circumferential array. The limiting assembly 32 includes a rotating ring 321 rotatably connected to the inner wall of the toothed ring 312. The outer wall of the injection molding tube 111 is fixedly connected to... There is a second toothed ring 322, which meshes with a first toothed ring 312. A spring 323 is installed inside the second toothed ring 322. The front side of the spring 323 is fixedly connected to the rotating ring 321, and the rear side of the spring 323 is fixedly connected to the second toothed ring 322. The spring 323 is in a stretched state. The transmission component 2 includes a handle 313 fixedly connected to the outer wall of the first toothed ring 312.

As the toothed ring 312 continues to move, it will disengage from the toothed ring 322. After the toothed ring 312 and the toothed ring 322 disengage, the handle 313 can be rotated. When the handle 313 rotates, it will cause the connecting ring 311 and the turntable 211 to rotate. When the turntable 211 rotates, it will cause the vortex groove 223 on its inner wall to rotate accordingly. When the vortex groove 223 rotates... Several sliders 222 will be pushed away from each other and slide on the T-shaped slide bar 221. As the sliders 222 move away, they will extend out from the limiting hole 213 and contact the inner wall of the injection port. After the sliders 222 contact the inner wall of the limiting hole 213, the sealing plate 214 can be fixed, thereby achieving the sealing effect. After the sealing is completed, stop pushing the handle 313. At this time, the spring 323 will pull back the rotating ring 321. When the rotating ring 321 is pulled back, the toothed ring 312 and the handle 313 will also be pulled back. After the toothed ring 312 is pulled back, it will mesh with the toothed ring 322 again, thereby achieving the effect of restricting the rotation of the toothed ring 312 again.
