Title:
PROCESSING DEVICE FOR INTERIOR OF PIPELINE
Document Type and Number:
WIPO Patent Application WO/2019/000648
Kind Code:
A1
Abstract:
A processing device for the interior of a pipeline, comprising: a flexible transmission shaft (100) having a first end and a second end opposite to the first end; a support (200) having a circular shape; and a driving device (300) connected with the second end. An axis of the support is connected with the first end, and several rollers coming into contact with the inner wall of the pipeline (1) are provided at intervals on the periphery of the support (200). The driving device (300) can transmit a twisting force to the support (200) by means of the flexible transmission shaft (100) so as to drive the support (200) to move in a length direction of the pipeline (1), thereby implementing cleaning, unclogging and polishing on the inner wall of the pipeline; and the driving device (300) can transport an object to be transported to a target position by means of the support (200), which is not influenced by the shape of the pipeline. The processing device for the interior of a pipeline can be applied to interior processing of the pipeline, and does not require dismounting or cutting the pipeline, thus saving a great amount of labor, time and material resources.
