Problems solved by technology

The existing screw moving device drives the drive frame with the drive wheel to rotate, and then the drive frame drives the drive wheel mounted on the edge of the drive frame to spiral along the inner wall of the pipeline to generate axial propulsion to make the robot go straight forward. The energy loss of this structure is large, and the transmission motion is unreliable
The existing pneumatic peristaltic crawling device has a relatively slow speed and a relatively complicated control system

Abstract

The invention discloses a peristaltic pipeline robot, which belongs to the technical field of pipeline robots. The present invention includes a fixed housing, a front airbag and a rear airbag. A rotary screw sleeve is arranged inside the fixed housing, a screw is arranged on the inner ring of the rotary screw sleeve, and front airbags are respectively connected to both sides of the fixed housing. Air bag and rear air bag, the outer side of front air bag and rear air bag are respectively provided with end cover, and the end cover of front air bag side is equipped with screw drive motor, and screw drive motor drives screw rod through bevel gear. The invention can adapt to pipes with different pipe diameters within a certain range. It is easy to use and has good flexibility. It adopts a modular design and can form a serial peristaltic pipe robot to improve the pushing and pulling capabilities, thereby improving the carrying capacity of task loads and effectively Improve the convenience of pipeline inspection and maintenance.

Description

technical field [0001] The invention relates to the technical field of pipeline robots, and more specifically, relates to a peristaltic pipeline robot. Background technique [0002] After a period of operation, the pipeline will be damaged such as corrosion, cracks, dents or deformation. Due to the narrow space inside the pipeline, pipeline robots are required to replace manual inspections of pipelines and repair damaged pipelines. Due to the needs of the environment and operating conditions, pipeline robots with various driving modes have gradually been developed. There are 8 basic types: pipeline pig, wheel, crawler, support, walking, peristaltic, spiral and snake. [0003] For example, Chinese patent 2007100500568 discloses a pipeline robot driven by a screw. Its DC motor shaft is equipped with a driving wheel frame. The end is equipped with a drive wheel, the angle between the axis of rotation of the drive wheel and the axis of the body is 3 to 30 degrees, and a guide w...
