Active speed-adjustable intelligent pipeline plugging robot

Abstract

The invention discloses an active speed-adjustable intelligent pipeline plugging robot. The robot comprises a first parking sealing mechanism, a crawling mechanism, a second parking sealing mechanism, a pigging speed regulating mechanism and the like, the pigging speed regulating mechanism is located at the lowest end, and the second parking sealing mechanism is connected to the upper portion of the pigging speed regulating mechanism through a connecting rod. The crawling mechanism is connected between the first parking sealing mechanism and the second parking sealing mechanism through a connecting rod, a plugging mechanism conducts plugging and anchoring through slip opening and closing and rubber deformation, and the crawling mechanism is matched with a front plugging mechanism body and a rear plugging mechanism body through hydraulic pistons to conduct crawling movement. The pigging speed regulating mechanism controls the overall movement speed through rubber deformation and compensates movement abrasion of rubber. According to the robot, intelligent plugging of an oil and gas transportation pipeline can be achieved, the robot can smoothly pass through complex pipeline conditions through rebound of rolling wheels, pigging rubber can continuously and efficiently conduct pigging speed regulation, the robot can accurately move to a designated working point through the crawling mechanism, and rapid, safe and accurate plugging in the oil and gas transportation pipeline first-aid repair and maintenance operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of maintenance and rescue of oil and gas pipelines, and in particular relates to a pipeline intelligent plugging robot of a rubber flow control and speed regulation type. Background technique [0002] Pipeline transportation is the most economical and reasonable transportation method for oil and gas. At present, my country has formed a number of oil and gas regional pipeline networks, and with the rapid development of the energy industry, my country's oil and gas pipeline construction will continue to make great progress. With the increase of pipeline laying length and service life in our country, it is necessary to carry out planned maintenance on pipelines. During the maintenance process, it is inevitable to use pipeline sealing technology to isolate the conveying medium inside the pipeline. At present, the pressurized opening and sealing technology is widely used in China to seal maintenance pipelines. ...
