Description

A pipeline repair device

technical field

The utility model is applicable to the technical field of pipeline repair, in particular to a pipeline repair device.

Background technique

At present, many municipal pipes such as underground drainage pipes and power pipes have different damage phenomena such as deformation, misalignment, and disjoint.

However, when using a repair mechanism to repair a deformed pipeline, it is necessary to use the corresponding conical head to expand and push the inner wall of the pipeline, so that the deformed position can be pushed to restore the deformation. For pipelines with different inner diameters, the outer side of the simple conical head cannot fully contact the inner wall of the pipeline, and when it is pushed, it cannot provide sufficient driving force for the deformed position of the pipeline to restore its deformation, thereby affecting the repair quality of the deformed pipeline. Therefore, we propose a pipeline repair device.

As an optional solution of the technical solution of the present application, the top surface of the extension pipe and the top surface of the connecting rod are both fixedly installed with a connecting sleeve, and the outside of the bottom of the fixed pipe is screwed to the inside of the connecting sleeve.

By adopting the above-mentioned technical solution, by connecting the sleeve to ensure that the arc plate is stretched, it can carry out squeeze recovery treatment on different positions inside the pipeline to be repaired, and further improve the applicability of the whole device.

Compared with the prior art, the utility model has the following beneficial effects:

A pipeline repair device according to the technical solution of the present application uses a fixed rod to rotate and install the adjusting frame on the inner surface of the stretching arc plate, and connects the side of the fixing rod to the outside of the adjusting sleeve through a rotating shaft, so that when the adjusting sleeve is lifted vertically along the outside of the fixing tube, it can provide an inward driving force to the four sets of stretching arc plates located on the outside of the mounting plate under the driving action of the push rod, so that the inside of the stretching arc plate can be pushed against the inner side, and then the center of the hinged joint with the mounting plate is used as the center of the stretching arc. It is fitted to the inner wall of the pipeline to be repaired with different inner diameters, and the inner wall of the pipeline is resisted to perform deformation restoration and repair treatment, so as to improve the applicability of the whole device;

With the connecting sleeve provided on the top of the extension tube, the bottoms of multiple sets of extension tubes can be sequentially screwed into the corresponding connecting sleeves, and then multiple sets of extension tubes can be spliced and extended to further increase the moving distance of the fixed tube inside the pipeline to be repaired, and ensure that different positions inside the pipeline to be repaired can be squeezed and restored, further improving the applicability of the entire device.
