Embodiment Construction

[0025] Attached below Figure 1-3 The present invention is further described with specific embodiments, and the peristalsis of this mechanism in a vertical pipeline is taken as an example below.

[0026] Such as figure 1 As shown, the foldable pipeline peristaltic mechanism includes two movable platforms 2 and a foldable link group 3 flexibly connecting opposite sides of the two movable platforms 2 .

[0027] The above-mentioned movable platform 2 is automatically expanded and contracted along the radial direction of the pipeline, supports the inner wall of the pipeline in the expanded state, and separates the inner wall of the pipeline in the contracted state. The movable platform 2 is equipped with various devices or tools, such as detection and flaw detection devices ; Welding tools can also be installed on the movable platform 2, so as to carry out the welding process in the pipeline.

[0028] The above-mentioned foldable link group 3 can be automatically folded, and the...

Abstract

The invention relates to a foldable pipeline peristaltic mechanism in the field of pipeline robots, comprising two movable platforms and a foldable connecting rod group flexibly connecting opposite sides of the two movable platforms; the movable platform is automatically expanded and contracted along the radial direction of the pipeline, Support the inner wall of the pipeline in the unfolded state, and separate the inner wall of the pipeline in the contracted state. Various devices or tools are mounted on the movable platform; the foldable connecting rod group can be automatically folded and set, and the folding direction is perpendicular to the unfolding of the movable platform , Shrinkage direction. The advantages are good rigidity and simple structure. After folding, the volume becomes smaller, which is convenient for people to carry and transport. After unfolding, it can be used for detection and flaw detection of large pipelines.

Description

technical field [0001] The invention relates to the field of pipeline robots, in particular to a peristaltic pipeline parallel mechanism. Background technique [0002] Today, with the continuous development of scientific and technological productivity, the continuous improvement of people's living standards and the growing needs of people, pipelines play a huge role in modern industry and agriculture and people's daily life, and are widely used in petroleum, chemical, natural gas, Nuclear industry, urban water and many other fields. These fields are related to the economic lifeline of the country. Once the pipeline leaks, it will bring huge losses to the country and the people. Therefore, it is of great significance to conduct regular inspection and maintenance of pipelines in various fields. [0003] The pipeline robot is a mechanism that can walk along the inner wall or outside of the pipeline. It can carry various detection devices and operating tools, and automatically ...
