Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair equipment, in particular to a pipeline repair equipment based on laser calibration technology. Background Art

[0002] There are two main methods for repairing underground pipelines: one is excavation repair and replacement of pipelines, and the other is trenchless repair. Currently, trenchless repair methods mainly include in-situ solidification method, interlacing method, pipe bursting method, folded lining method and spraying method to solve structural defects and leakage problems.

[0003] Therefore, it is necessary to use a pipeline repair equipment based on laser calibration technology to repair the pipeline.

[0004] For example, the prior art Chinese patent publication number "CN213065101 U" provides a pipeline repair equipment based on laser calibration technology, including a hydraulic device, the hydraulic device includes a bottom plate and a sliding shoe connected to the bottom plate, the sliding shoe includes a connecting column connected to the bottom plate and a chassis, the chassis is protruding with a connecting block, the side of the connecting block away from the chassis is provided with an embedding groove for the connecting column to be embedded, the connecting block is provided with a connecting hole connected to the embedding groove, and a connecting screw connected to the connecting block by a thread is passed through the connecting hole.

The connecting column is embedded in the mounting groove of the chassis, and the connecting column and the chassis are connected by connecting screws, so that the connecting column and the chassis are detachably connected. After the chassis is damaged, the chassis is removed from the connecting column and replaced.

[0006] In the existing pipeline repair equipment based on laser calibration technology, the bottom plate and top plate parts at the upper and lower ends of the hydraulic cylinder are directly fixedly connected to the top and bottom ends of the hydraulic cylinder. The hydraulic cylinder is an important structure and is frequently used, which makes it inconvenient to disassemble and replace the hydraulic cylinder after a failure of the hydraulic cylinder. In addition, no connecting and positioning structure is provided between the top plate and the bottom plate, which easily causes shaking and misalignment and tilting between the top plate and the bottom plate, resulting in inaccurate deviations in pipeline repair. At the same time, due to the large degree of concavity and bending of the pipeline, the height of the pipeline repair equipment is too high to enter the pipeline repair site for repair, and an adjustment structure is not provided at the bottom end of the pipeline repair device to adjust the height of the pipeline repair device.
