Description

Technical Field

[0001] The utility model relates to the technical field of pipe network winding repair, in particular to a pipe network winding repair device. Background Art

[0002] At present, urban sewage pipes are the "underground lifeline" of the city, shouldering the important task of urban sewage and drainage. However, due to the complex underground environment, the pipes are prone to aging and corrosion after long-term use; in addition, there are sometimes some corrosive chemical components in the sewage transported by the pipes; these factors can easily lead to water leakage in the pipes, causing problems such as road waterlogging and collapse, so the pipes need to be repaired.

[0003] The trenchless pipeline repair method is to repair the pipeline partially or completely without excavating the pipeline. Compared with the traditional pipeline excavation repair, it has the advantages of less pollution, shorter construction period, and less impact on traffic. The more mature trenchless pipeline repair methods in China mainly include soft lining method, interlacing method and spiral winding method. The spiral winding method is to simultaneously send the prefabricated strip profiles in the factory to the winding machine pre-installed in the inspection well, and advance it in a spiral winding manner to manufacture a new pipe in the old pipe, and then pour cement slurry between the new pipe and the old pipe, so as to finally form a new type of pipeline with high strength and good water tightness.

[0004] Publication number "CN212004760U" provides a spiral winding pipe repair device, in which the guide port on the guide frame can limit the movement of the profile, reduce the deviation of the profile due to shaking during movement, and further improve the stability of the profile during transportation. By setting a connecting piece, the transportation of the winding cage into the manhole can be more convenient, and by setting a guide frame, the transportation of the profile can be smoother.

[0005] However, the above technical solutions and the prior art have the following defects:

[0006] Firstly, the spiral winding pipe repair device does not have a corresponding auxiliary support structure to support and position the winding cage, which causes the circular winding cage to easily roll back and forth during use, thereby affecting the folding spiral winding stability of the internal profile of the winding cage. Secondly, the conveying component in the spiral winding pipe repair device does not have the ability to scrape and clean impurities and dust on the outer surface of the profile. Since the profile needs to be inserted into the manhole before entering the conveying component, during this process, the profile is very easy to touch the inner wall of the manhole and adhere to dust and impurities. If the adhered dust and impurities are not cleaned in time, it will affect the smoothness of the subsequent guiding of the profile. Therefore, its practicality needs to be improved.

[0035] Working principle: After the winding cage body 4 is transported to the required position in the underground manhole by external lifting equipment, the staff first sets the multiple connecting seats 57 on the annular side surfaces of the multiple extension screws 55. At this time, the multiple support rods 53 are swung back and forth respectively to adjust the use angle of the support rods 53. After the adjustment is completed, the multiple locking nuts 56 are fixed to the annular side surfaces of the multiple extension screws 55 with the help of an external wrench to lock the multiple connecting seats 57. Then, the multiple extension struts 51 are respectively set on the lower sides of the annular side surfaces of the multiple support rods 53. At this time, the extension struts 51 can be telescopically adjusted to adjust the use position of the extension struts 51. After the adjustment is completed, the multiple fixing screws 54 are fixed in the multiple internal threaded through holes 511 with the help of an external wrench, so that the multiple extension struts 51 can be fixed. At this time, the extension struts 51 and the support rods 53 will assist in supporting the winding cage body 4 through the connecting seats 57 and the extension screws 55 (reference Figure 2 ), to prevent the winding cage 4 from rolling forward and backward during use, thereby ensuring the stability of the winding cage 4; when it is necessary to guide the strip profile 1 into the winding cage 4, the staff first passes one end of the strip profile 1 through the primary guide roller 25, the active guide roller 26 and the secondary guide roller 28 respectively, and then the low-speed motor 29 can be started to drive the active guide roller 26 to rotate at a low speed (the rotation direction of the active guide roller 26 is Figure 2 ), so that the active guide roller 26 rotating at a low speed actively guides the strip profile 1 downward to the winding cage 4 and spirally winds it into a tubular shape (reference Figure 1 ) Repair the inside of the external pipe network. During this process, the first-level guide roller 25 and the second-level guide roller 28 can limit and guide the strip profile 1 to avoid large deviation or shaking of the strip profile 1 during the guiding process. At the same time, the front scraper seat 23 and the rear scraper seat 24 can scrape off most of the dust and impurities adhered to the front and rear ends of the strip profile 1 to avoid dust and impurities affecting the smoothness of the guiding of the strip profile 1. When all the strip profiles 1 are guided to the inside of the winding cage 4, the low-speed motor 29 can be turned off.
