Hose cleaning robot

Abstract

The invention provides a hose cleaning robot and relates to the field of pipeline inner wall crawling robots. In order to meet the requirements for crawling and cleaning of the inner wall of a hose, the robot for crawling on and cleaning the inner wall of the hose is designed. The robot comprises an upper fixing mechanism, a lower fixing mechanism and a middle heading mechanism. The two fixing mechanisms are located at the two ends of the middle heading mechanism respectively to achieve the fixing effect. The middle heading mechanism is in charge of connecting a whole machine, pushes the upper fixing mechanism to move forwards and pulls the lower fixing mechanism to ascend. Both the upper fixing mechanism and the lower fixing mechanism are designed as slider crank mechanisms to achieve the expanding, fixing, shrinking and separating functions. Curved face supporting boards driven by the upper fixing mechanism form a bud shape when folded, so that a road is opened; and when unfolded, the curved face supporting boards make tight contact with the inner wall of the hose to achieve the fixing effect. The two ends of a supporting board of the lower fixing mechanism are provided with telescopic rods, so that linear motion of the supporting board is guaranteed, and the supporting board is supported stably when fixed. A lead screw slider module is adopted for designing the middle heading mechanism, so that the heading function is achieved.

Description

technical field [0001] The invention relates to the field of pipeline inner wall crawling robots, in particular to a hose inner wall cleaning robot used for crawling and cleaning in flexible pipelines. Background technique [0002] At present, the existing pipeline robots can be roughly divided into eight types according to different driving modes. They are mobile robots, which have no driving device, and only follow the fluid flow in the pipe. They are passive robots that do not need to consume energy, but their movement modes are quite limited; wheeled robots, this type of robot is widely used in pipeline inspection. At present, many commercial robots are of this type; tracked robots, which use crawlers instead of wheels; The robot moves through mechanical feet, but this type of robot requires a large number of drivers and is difficult to control; the sixth type is the peristaltic robot, which moves forward through the expansion and contraction of the body like an earthwo...
