Automatic travelling pipeline repair device and pipeline repair method

Abstract

The invention discloses an automatic travelling pipeline repair device and a pipeline repair method. The automatic travelling pipeline repair device comprises a repair device body used for repairing a pipeline with a sunken inner wall, a travelling oil cylinder used for driving the repair device body to travel, and a supporting oil cylinder used for keeping the traveling oil cylinder to arrange inside a to-be-repaired pipeline in parallel; the travelling oil cylinder is arranged inside the to-be-repaired pipeline in parallel; one end of the travelling oil cylinder is connected with the repair device body; and the other end of the repair device body is connected with the supporting oil cylinder. According to the automatic travelling pipeline repair device disclosed by the invention, the repair device body, the travelling oil cylinder and the supporting oil cylinder are arranged, the repair device body is used for repairing the sunken pipeline, the travelling air cylinder is used for travelling the whole device, and the supporting oil cylinder is used for balancing stability of the whole device, so that the whole device can automatically realize free travelling and pipeline repair work inside the pipeline.

Description

technical field [0001] The invention relates to a pipeline repair technology, in particular to an automatic walking pipeline repair device and a pipeline repair method, the device is used to repair damaged pipelines, weakened pipelines or leaking pipelines in areas that are difficult for workers to enter, such as sewage pipes, water supply pipes, etc. Main network, wells and gas pipelines. Background technique [0002] At present, many pipelines buried underground are intersected and intricate. Some pipelines have been used for many years, and leakage and rupture accidents frequently occur. Most of these pipelines are laid in densely populated and commercially prosperous urban areas. Excavation construction will Causing traffic jams, destruction of green spaces and gardens, the process of excavating and repairing pipelines often causes damage to other pipelines. Some pipelines have small diameters and no working faces, so personnel cannot enter the pipelines for repairs. Th...

[0002] At present, many pipelines buried underground are intersected and intricate. Some pipelines have been used for many years, and leakage and rupture accidents frequently occur. Most of these pipelines are laid in densely populated and commercially prosperous urban areas. Cause traffic jams, damage to green spaces and gardens, and the process of excavating and repairing pipelines often causes damage to other pipelines. Some pipelines have small diameters and no working surfaces, so personnel cannot enter the pipelines for repairs

There is another fatal problem in the pipelines in the city. Most of the underground pipelines are airtight and there is a lot of deadly poisonous gas. People cannot enter the pipeline network for repairs.
