Pipeline inner wall cleaning robot

Abstract

The invention provides a pipeline inner wall cleaning robot, which comprises a main flow pipe and toggle pieces. A fixing ring is arranged in the middle of the outer side of the main flow pipe, the periphery of the fixing ring is connected with the front ends of movable rods correspondingly, first springs are arranged around the outer wall of the rear end of the main flow pipe correspondingly, ejector robs are arranged at the ends, away from the central point of the main flow pipe, of the first springs correspondingly, the ejector robs are connected with sliding grooves correspondingly, the sliding grooves are formed in the rear ends of the ejector robs, pulleys are arranged at the rear ends of the ejector rods, the front end of the main flow pipe is connected with the rear end of a fixingdisc, a jet hole is formed in the front side of the fixing disc, the outer side of the fixing disc is connected with a rotary table through a support rod, inner grooves are formed in the fixing disc,and second springs are arranged in the inner grooves correspondingly. According to the provided self-travelling oil pipeline internal cleaning device, the structure is simple, continuous working in aclosed pipeline is facilitated, the cleaning efficiency is effectively improved, thus the cleaning period is shortened, and the practicality is improved.

Description

technical field [0001] The invention relates to the technical field related to petroleum transportation, in particular to a pipeline inner wall cleaning robot. Background technique [0002] When oil is transported, it is usually transported through closed pipelines. Oil pipelines are pipelines for transporting crude oil and / or refined oil products. Special pipelines in oil fields are important infrastructures that ensure the transfer and storage of crude oil produced and the separation of sewage back into the ground. , and some impurities in crude oil are very easy to adhere to the inner wall of the oil pipeline, so it will affect the service life of the pipeline, and the oil pipeline needs to be cleaned regularly. [0003] At present, when cleaning the oil pipeline, it is necessary to stop the transportation of crude oil, which will greatly reduce the transmission efficiency, and the disassembly process needs to consume a lot of time and labor costs, which is inconvenient i...
