[0032] Example 1

[0033] This embodiment provides a technical solution: a pipe jacking construction sealing device for municipal pipeline engineering, such as... Figures 1-5 As shown, it includes a municipal pipeline top cover body 7, an intermediate contact sealing cover, a middle cover sealing rotation mechanism, a sealing and fixing outer ring, and a pneumatic expansion sealing mechanism.

[0034] The intermediate contact sealing cover is installed and connected to the inner upper part of the municipal pipeline top cover body 7. The intermediate contact sealing cover can seal and block the interior of the municipal pipeline top cover body 7. The intermediate cover sealing rotation mechanism is installed and connected to the middle of the upper part of the intermediate contact sealing cover. The intermediate contact sealing cover can be adjusted and installed through the intermediate cover sealing rotation mechanism. The sealing fixing outer ring is fixed to the periphery of the intermediate contact sealing cover. The intermediate contact sealing cover can be stably placed through the fixing of the sealing fixing outer ring. The sealing fixing outer ring is fixed to the municipal pipeline top cover. On the periphery of the main body 7, the sealing and fixing outer ring can be effectively fixed to the periphery of the municipal pipeline top cover 7. The pneumatic expansion sealing mechanism is installed and connected to the middle abutting sealing cover. The pneumatic expansion sealing mechanism is placed through the installation of the middle abutting sealing cover. The pneumatic expansion sealing mechanism is located in the middle of the interior of the municipal pipeline top cover 7. The pneumatic expansion sealing mechanism can receive gas and expand, so that the pneumatic expansion sealing mechanism can expand and be tightly installed inside the municipal pipeline top cover 7, thus achieving a tight sealing installation.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the intermediate blocking cover includes an intermediate blocking cover shell 1 fitted inside the municipal pipeline top cover body 7. The intermediate blocking cover shell 1 can effectively block the internal area of ​​the municipal pipeline top cover body 7. A rotating mechanism mounting groove 51 is opened in the middle of the interior of the intermediate blocking cover shell 1. The intermediate blocking cover shell 1 is threadedly connected to the intermediate cover blocking rotating mechanism through the rotating mechanism mounting groove 51. The intermediate cover blocking rotating mechanism can rotate on the intermediate blocking cover shell 1. A T-shaped post 13 is fitted on the inner side of the rotating mechanism mounting groove 51 on the intermediate blocking cover shell 1. When the intermediate cover blocking rotating mechanism rotates downward, it can contact the T-shaped post 13. A sloping groove 211 is opened on the upper side of the inner end of the T-shaped post 13. The T-shaped post 13 contacts the T-shaped post 13 through the sloping surface of the sloping groove 211, so that the T-shaped post 13 can move outward inside the intermediate blocking cover shell 1. The outer end of the T-shaped post 13 is located in the middle. An abutment post 12 is fitted inside the middle plug shell 1. The T-shaped post 13 drives the abutment post 12 to move outward, so that the abutment post 12 contacts the inner wall of the municipal pipeline top cover body 7. This allows for stable placement and ensures that the middle plug shell 1 can be stably placed for sealing. A metal spring 11 is provided at the connection between the T-shaped post 13 and the abutment post 12. When the abutment force of the middle cover sealing rotation mechanism disappears, the elasticity of the metal spring 11 allows it to drive the T-shaped post 13 and the abutment post 12 back to their original positions. A pneumatic expansion sealing mechanism is installed on the inner side of the middle plug shell 1. The pneumatic expansion sealing mechanism can be stably placed on the middle plug shell 1. A sealing fixing outer ring is fixed to the upper outer wall of the middle plug shell 1. The middle plug shell 1 can be installed and placed accordingly through the sealing fixing outer ring at the outer end.

[0036] The middle cover sealing rotation mechanism includes a rotating handwheel 2, which is convenient for personnel to hold and rotate. A rotating stud 5 is fixedly connected to the lower middle of the rotating handwheel 2. When the rotating handwheel 2 rotates in the forward direction, it can drive the rotating stud 5 to rotate and move downward in the forward direction. A rounded contact head 21 is fixedly connected to the lower end of the rotating stud 5. The rotating stud 5 can drive the rounded contact head 21 to move downward, so that the rounded contact head 21 can contact the inclined groove 211 of the T-shaped post 13. This can squeeze the T-shaped post 13 to move outward. The rotating stud 5 is threadedly connected to the middle cover shell 1, which facilitates the threaded rotation and lifting.

[0037] The sealing and fixing outer ring includes a sealing outer ring 6. The sealing outer ring 6 has an installation sleeve hole 61 inside. The sealing outer ring 6 is fixed to the middle plug shell 1 through the installation sleeve hole 61, so that the sealing outer ring 6 can be installed and connected accordingly. The inner circumference of the sealing outer ring 6 is threaded with a fixing screw 4. The sealing outer ring 6 can be fixed to the circumference of the municipal pipeline top cover body 7 through the fixing screw 4, so that the sealing outer ring 6 can stably drive the middle plug shell 1 to be placed and sealed. The outer wall of the fixing screw 4 is fixed with a screw handle 41, which makes it easy for personnel to hold and rotate.

[0038] An installation collar hole corresponding to the municipal pipeline top cover body 7 is provided between the middle plug shell 1 and the sealing outer ring 6, so that they can be installed and connected accordingly.

[0039] In use, the intermediate contact sealing cover can be adjusted and installed via the intermediate cover sealing rotation mechanism, allowing it to seal and block inside the municipal pipeline top cover body 7. The sealing fixing outer ring is fixed to the periphery of the municipal pipeline top cover body 7. The intermediate contact sealing cover can be stably placed by fixing the sealing fixing outer ring. The pneumatic expansion sealing mechanism is placed through the installation of the intermediate contact sealing cover. The pneumatic expansion sealing mechanism can receive gas and expand, so that the pneumatic expansion sealing mechanism can expand and be tightly installed inside the municipal pipeline top cover body 7, which can tightly seal the installation and prevent external substances from entering.

[0040] Example 2

[0041] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 and Figure 4As shown, to further better realize this utility model, the following configuration is specifically adopted: The pneumatic expansion sealing mechanism includes an air inlet pipe 32 fixedly connected to the intermediate plug housing 1. The intermediate plug housing 1 can receive the gas delivered by the air inlet pipe 32. A valve 3 is fixedly connected to the upper end of the air inlet pipe 32. When inflating, the valve 3 opens, allowing external gas to be added through the air inlet pipe 32. A flange connecting pipe 31 is fixedly connected to the upper end of the valve 3. The flange connecting pipe 31 is connected to an external gas pipe, and the valve 3 can receive the external gas pipe through the flange connecting pipe 31. The lower end of the gas inlet pipe 32 is fixedly connected to an assembly cover 8. The assembly cover 8 can be fitted inside the municipal pipeline top cover body 7 for sealing and blocking. An expansion ring groove 81 is opened on the inner side of the outer end of the assembly cover 8. The assembly cover 8 can receive gas through the expansion ring groove 81. An expansion air bladder 82 is fixedly connected to the inner side of the expansion ring groove 81 on the assembly cover 8. The gas inside the expansion ring groove 81 can cause the expansion air bladder 82 to expand, thereby pneumatically expanding and sealing the municipal pipeline top cover body 7. This makes the sealing tighter and effectively prevents the entry of external substances.

[0042] The air inlet pipe 32 passes through the expansion ring groove 81 inside the assembly cover 8, making it easy for gas to pass through and be transported.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
