Problems solved by technology
Coating drag reduction has the disadvantages of short service life, narrow application range and complicated process, and the effect of drag reduction of pipeline coating is very weak
The drag reduction of drag reducer has the disadvantages of fast consumption of drag reducer, toxicity and inconvenient transportation, and the use of drag reducer to reduce drag in pipelines will increase the drag reducer injection device, so that the operation volume and failure rate of the entire system will be greatly reduced. improve
Therefore, at present, there is no better drag reduction method for oil and gas pipelines.

Embodiment Construction
[0023] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0024] combine Figure 1-11 , the operating process of the present invention is mainly completed by two moving links of walking and processing, which are divided into two modules of power head and processing assembly according to their different functions. Among them, the power head is responsible for the walking function of the entire robot, and the processing components only need to complete the processing of the bionic drag reduction surface structure. Such as figure 1 As shown, the pipeline processing robot adopts the overall layout form of the power head in the front, the processing components in the rear, and the connection between the power head and the processing components in the form of docking bayonet.
[0025] The power head of the pipe processing robot adopts a peristaltic travel mode. The power head consists of three parts: the front walking part, ...

The invention aims to provide a processing device and method for the inner-wall resistance reduction structure of a pipeline. The processing device comprises a walking part, a walking part motor, a processing part and a processing part motor, wherein the walking part comprises a guidance walking part, a front-section walking part and a rear-section walking part; the lower half part of the front-section walking part has the same structure with the upper half part of the front-section walking part; the walking part motor is installed between the front-section walking part and the rear-section walking part; the walking part motor comprises a flexible rod; the flexible rod is connected with the rear-section walking part; the rear-section walking part and the front-section walking part have the same structure and are symmetrically arranged; and the guidance walking part, a mechanism formed by the processing part and the processing part motor, the front-section walking part, the walking part motor and the rear-section walking part are successively connected. The processing device disclosed by the invention has the advantages of big operation pipe diameter range, good centering and positioning function, simple structure layout and easiness in realization.
Description
technical field [0001] The invention relates to a pipeline processing device and processing method. Background technique [0002] At present, the drag reduction technology is rarely used in domestic oil and gas pipelines, and most of them use coating drag reduction and drag reduction agent drag reduction methods, which have great disadvantages. Coating drag reduction has the disadvantages of short service life, narrow application range and complicated process, and the drag reduction effect of pipeline coating is very weak. The drag reduction of drag reducer has the disadvantages of fast consumption of drag reducer, toxicity and inconvenient transportation, and the use of drag reducer to reduce drag in pipelines will increase the drag reducer injection device, so that the operation volume and failure rate of the entire system will be greatly reduced. improve. Therefore, there is no better drag reduction method for oil and gas pipelines at present. Some domestic researchers...
