[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0028] Please refer to Figures 1-5 , the utility model provides a technical solution:

[0029] A reaming device for repairing a municipal drainage pipe network, including a first reaming column 1. One end of the first reaming column 1 is fixedly connected with a connecting column 2. The other end of the connecting column 2 is fixedly connected with a second reaming column 3. The second reaming column 3 is in a tapered shape. The outer surface of the connecting column 2 is provided with a plurality of annularly and equidistantly distributed reaming plates 6. The plurality of reaming plates 6 are all arranged in an arc structure and are movably connected to the outer surface of the connecting column 2. It further includes:

[0030] An expansion component, which is located inside the connecting column 2 and is used to drive the plurality of reaming plates 6 to expand, so as to ream the inside of pipes of different sizes;

[0031] A synchronization component, which is located inside the first reaming column 1 and is used to drive the expansion component and the second reaming column 3 to work simultaneously. As the reaming plates 6 expand and the second reaming column 3 advances, the entire device moves forward in the pipe while continuously expanding the inner diameter of the pipe.

[0032] Further, the expansion component includes a connecting frame 5 and sliding grooves 16. A plurality of annularly and equidistantly distributed sliding grooves 16 are formed inside the connecting column 2. A connecting frame 5 is slidably connected inside each of the plurality of sliding grooves 16. The plurality of connecting frames 5 are fixedly connected to the corresponding reaming plates 6. As the connecting frame 5 slides, the reaming plates 6 are gradually pushed outwards, changing from a state of being close to the connecting column 2 to an unfolded state, and starting to ream the inner wall of the pipe.

[0033] Further, a fourth gear 13 is rotatably connected to the center inside the connecting column 2. A third gear 12 is rotatably connected inside the connecting column 2. The third gear 12 is meshed with the fourth gear 13. A plurality of annularly and equidistantly distributed limiting grooves 14 are formed on the outer surface of the fourth gear 13. A movable column 15 is movably connected inside each of the plurality of limiting grooves 14. The plurality of movable columns 15 are fixedly connected to the corresponding connecting frames 5. The rotation of the fourth gear 13 causes the positions of the limiting grooves 14 on its outer surface to shift, thereby driving the movable column 15 to slide inside the limiting groove 14. Since the movable column 15 is fixedly connected to the connecting frame 5, the connecting frame 5 will slide inside the connecting column 2 along the sliding groove 16.

[0034] Further, the synchronization component includes a driving motor 7, a first gear 8 and a second gear 9. The inner wall of the other end of the first reaming column 1 is rotatably connected with the first gear 8 and the second gear 9. The first gear 8 is meshed with the second gear 9. The driving motor 7 is fixedly installed at the end of the first reaming column 1. The output end of the driving motor 7 is fixedly connected with the first gear 8. The driving motor 7 drives the first gear 8 to rotate. Since the first gear 8 is meshed with the second gear 9, the second gear 9 rotates accordingly.

[0035] Furthermore, a first rotating shaft 10 is rotatably connected inside the first reaming column 1. The first rotating shaft 10 passes through the connecting column 2 and extends to the outer surface of the second reaming column 3 and is fixedly connected to the second reaming column 3. The first rotating shaft 10 is fixedly connected to the first gear 8. The first rotating shaft 10 is fixedly connected to the first gear 8. The first rotating shaft 10 will also rotate as the first gear 8 rotates. The first rotating shaft 10 passes through the connecting column 2 and is fixedly connected to the second reaming column 3. Therefore, the tapered part of the second reaming column 3 will also rotate synchronously. The rotation of the second reaming column 3 can clean some blockages in the pipeline.

[0036] Furthermore, a second rotating shaft 11 is rotatably connected inside the first reaming column 1. The second rotating shaft 11 is fixedly connected to the second gear 9. The second rotating shaft 11 is fixedly connected to the third gear 12. The second rotating shaft 11 then drives the third gear 12 to rotate.

[0037] Furthermore, two symmetrically distributed handles 4 are fixedly connected to both sides of the end of the first reaming column 1. The device is sent into the pipeline to be repaired by operating the handles 4 on the first reaming column 1.

[0038] Working principle: When the staff needs to use the reaming device for repairing municipal drainage pipe networks, the device is sent into the pipeline to be repaired by operating the handles 4 on the first reaming column 1, and the driving motor 7 is started. The driving motor 7 drives the first gear 8 to rotate. Since the first gear 8 meshes with the second gear 9, the second gear 9 rotates accordingly. The rotation of the second gear 9 drives the second rotating shaft 11 fixed to it to rotate. The second rotating shaft 11 then drives the third gear 12 to rotate. The third gear 12 meshes with the fourth gear 13. Therefore, the fourth gear 13 also starts to rotate. As the fourth gear 13 rotates, the position of the limiting groove 14 on its outer surface shifts, thereby driving the movable column 15 to slide in the limiting groove 14. Since the movable column 15 is fixedly connected to the connecting frame 5, the connecting frame 5 will slide inside the connecting column 2 along the sliding groove 16. As the connecting frame 5 slides, the reaming plate 6 is gradually pushed outwards, changing from a state of being close to the connecting column 2 to an unfolded state, and starts to ream the inner wall of the pipeline. Since the first rotating shaft 10 is fixedly connected to the first gear 8, the first rotating shaft 10 will also rotate as the first gear 8 rotates. The first rotating shaft 10 passes through the connecting column 2 and is fixedly connected to the second reaming column 3. Therefore, the tapered part of the second reaming column 3 will also rotate synchronously. The rotation of the second reaming column 3 can clean some blockages in the pipeline. As the reaming plate 6 expands and the second reaming column 3 advances, the entire device moves forward in the pipeline while continuously expanding the inner diameter of the pipeline.

[0039] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
