Problems solved by technology

Deformed pipelines seriously affect medium transportation and pipeline safety. At present, there is no feasible repair technology for deformed pipelines. The only way to repair deformed pipe sections is to cut and replace them.
This repair method usually requires medium stoppage, long operation time and high maintenance cost

Embodiment Construction

[0017] The present invention is not limited by the following implementation examples, and specific implementations can be determined according to the technical solutions and actual conditions of the present invention. Combine below figure 1 , figure 2 , image 3 The present invention will be described below. The positional relationship of up, down, left and right is based on the instructions attached figure 1 The layout direction is determined.

[0018] The front end cover 2 is in the shape of a disk as a whole and a cylinder is arranged in the middle position. The base 4 is in the shape of a cylinder with a bottom cover as a whole. The base 4 is buckled at the center of the front end cover 2 and fits with the cylinder of the front end cover 2. An outer ring groove is arranged at the middle position on the outside of the cylinder of the base 4, and the front end cover 2 is provided with a screw at the corresponding position and the front end cover 2 and the base 4 are axially f...

Abstract

The invention relates to a radial stretching type concave pipe maintenance device used for reshaping repair construction of instable pipelines, locally deformed pipelines and deformed barrels. Through the technical scheme, an outer barrel is arranged outside an inner barrel, the inner barrel is arranged on a substrate, the substrate is sleeved in a front end cover, a hydraulic motor is arranged on the substrate, a first T-shaped groove is formed in the radial direction of the front end cover, reshapers are arranged in the radial direction of the front end cover, front oil cylinders are arranged between the front end cover and the reshapers, a second T-shaped groove is formed in the radial direction of a rear end cover, slips arranged in the radial direction of the rear end cover, rear oil cylinders are arranged between the rear end cover and the slips, one end of a middle oil cylinder is arranged at the central position of the substrate, and the other end of the middle oil cylinder is fixed in the outer barrel through a mounting plate. The slips and the reshapers are driven by the independent oil cylinders, the radial stretching distance can be adjusted independently, the rebounding of deformed parts of a pipeline can be taken into account in the reshaping process, and the reshaping effect is good.

Description

Technical field [0001] The invention relates to a radially open type concave pipe repairer, which is used for the plastic repair construction of unstable pipelines, partially deformed pipelines and deformed cylinders. Background technique [0002] In fluid medium transportation, compared with tank transportation, pipeline transportation has the advantages of large transportation volume, continuous transportation, and low operating cost. It is widely used in the transportation of oil, water, gas and other fluids. Generally, pipelines are laid buried in the ground. Under special working conditions such as landslides, mudslides, heavy-duty squeezing, etc., the pipelines will be squeezed and deformed, and even large deformations due to instability will occur. The deformed pipeline seriously affects the medium transportation and pipeline safety. Currently, there is no feasible repair technology for the deformed pipeline, and the deformed pipe section can only be repaired by cutting an...
