Description
Technical Field
[0001] The utility model belongs to the field of trenchless repair of pipelines, and in particular relates to a trenchless integral repair device for large-diameter pipelines. Background Art
[0002] At present, underground pipelines are responsible for the important tasks of urban sewage and flood drainage, so the maintenance of underground pipelines is of great significance. If underground pipelines are damaged during long-term use, they need to be repaired in time. The traditional pipeline repair method is to replace new pipelines by excavation, which makes the project huge, costly, and long in construction period, and will also lead to problems such as traffic jams and environmental pollution. The trenchless pipeline repair method is to repair the pipeline partially or as a whole 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. At present, the common trenchless pipeline repair methods mainly include soft lining method, interlacing method and spiral winding method.
[0003] Among them, the spiral winding method is to simultaneously send the prefabricated strip profile in the factory into the spiral winding repair device pre-installed in the inspection well, and advance it in a spiral winding manner to make a new pipe inside the old pipe, and then pour cement slurry between the new pipe and the old pipe, finally forming a new type of pipeline with high strength and good water tightness.
[0004] The existing spiral winding repair device is provided with an annular bracket, on which a guide roller is installed. The strip profile is guided to spirally wind to form a new tube through the grooves of the guide roller. Therefore, during assembly, it is necessary to accurately adjust the position of each guide roller so that the connecting line of all the guide rollers finally forms a spiral line, so that the strip profile can form a new tube under the action of the spiral winding repair device.
[0005] With respect to the above-mentioned related technologies, during the assembly of the annular bracket device, since the position of each guide roller is fixed, it is difficult to quickly disassemble it when the pipeline size changes or the guide roller is damaged, which increases the complexity and cost of maintenance. At the same time, when faced with profiles of different sizes or types, it is difficult to quickly adjust the setting of the guide column, which limits the flexibility and adaptability of the winding machine. Therefore, a non-excavation integral repair device for large-diameter pipelines is proposed to solve the above problems. Utility Model Content

[0010] A limit bracket is installed on the side of the mounting seat, and a clamping slider is slidably arranged in the limit bracket;

[0012] As a further improvement of the present invention, the limiting bracket is arranged in a door shape and is detachably assembled on the side of the mounting seat by means of hexagon socket bolts.
[0013] As a further improvement of the utility model, the clamping slider is a rectangular block structure and a triangular notch is opened on its side; wherein two of the slide grooves are penetrated by positioning bolts, one end of the two positioning bolts passes through the mounting block and is threadedly connected with a nut, and the mounting block is detachably mounted on the mounting seat by the positioning bolts.
[0014] As a further improvement of the present invention, a base is also installed on the side of the mounting seat, and a shaft sleeve is integrally arranged at the center of the base. The shaft sleeve is engraved with a threaded line and is threadedly connected with an adjusting screw, one end of the adjusting screw passes through the side seat and abuts against the side of the clamping slider; a tensioning bolt member is arranged on the mounting seat, and the tensioning bolt member includes a rod body and a nut member matched therewith, and the base is detachably arranged on the mounting seat through the tensioning bolt member.

When the guide roller 4 is damaged, the guide rollers 4 in the two groups of positioning components 2 can be independently disassembled, assembled and replaced without affecting the work of the remaining guide rollers 4, thereby speeding up the overall construction efficiency and greatly reducing the repair cost.
[0032] Furthermore, in actual use, by opening a plurality of slide grooves 22 on the mounting seat 21, the installation position of the positioning assembly 2 can be freely adjusted on the positioning plate 1, so that two adjacent guide rollers 4 can be installed at different spiral angles, thereby better spirally guiding the pipeline repair profile.
