Abstract

The invention discloses a crawler for non-excavation repair of a pipeline. The main points of the technical scheme are that the crawler for the non-excavation repair of the pipeline comprises a main body; a mounting frame is arranged at the first end of the main body; a camera device is arranged on the mounting frame; a storage cavity is also formed in the main body; the storage cavity is filled with a pipeline repair agent; the storage cavity is connected with a pipeline pump through the pipeline; a spraying head is also arranged on the mounting frame; the spraying head is connected with the pipeline pump through a guide pipe; therefore, an image in the pipeline is shot through the camera device; when a crack in the pipeline is found, the pipeline pump is controlled to start; the pipeline pump pumps the pipeline repair agent in the storage cavity; the pipeline repair agent is pressurized and is sprayed out from the spraying head under the action of the pipeline pump so as to be sprayed on the crack to achieve the purpose of repairing the crack. Compared with a conventional crawler, the crawler for the non-excavation repair of the pipeline is more energy-saving, environment-friendly, low-carbon and resource-saving, and contributes to green development.

Description

technical field

[0001] The invention relates to the field of crawlers, in particular to a crawler for non-excavation repair of pipelines. Background technique

[0002] With the rapid development of my country's economy, the total length of various existing pipelines has been very long. Due to the long laying time of many underground pipelines, and the poor construction technology and pipeline materials at that time, these pipelines have been damaged due to corrosion and overload during the perennial operation. , Foundation subsidence or human factors cause partial damage, road surface subsidence and other accidents, resulting in huge economic losses. At present, the commonly used pipeline repair method is the lining repair method, and the main technologies for partial repair of trenchless pipelines include stainless steel thin plate welding lining and pipeline spraying lining.

[0003] When performing partial repair of non-excavation pipelines, firstly, the pipeline crawler ...
