Abstract
A machine for pipe maintenance, which travels forward through a pipeline and effectively removes foreign substances sticking to the inside of a pipeline, using friction members 70 that are moved along the inside of the pipeline by a rotator assembly 30 and rotated by rotating shaft assemblies 50, which come in contact with the inside of the pipeline is disclosed. Further, rotating shaft assemblies 50 and a rotator assembly 30 are respectively rotated by first and second rotating units 40, 60, such that it is possible to maximize the effect of removing foreign substances in the pipeline by smoothly rotating the friction members 70, and also improve durability by preventing an erroneous operation and damage due to load that is applied during the operation.
Claims13
A machine for pipe maintenance comprising:
- a base housing that is provided with wheel at the lower portion;
- a traveling unit that is disposed in the base housing and moves the base housing through a pipeline by rotating the wheels;
- a rotator assembly that is rotatably connected to the front of the base housing;
- a first rotating unit that is disposed in the base housing and rotates the rotator assembly;
- rotating shaft assemblies that are rotatably connected to the outer side of the rotator assembly and protrude outside at predetermined distances;
- a second rotating unit that is disposed in the base housing and rotates the rotating shaft assemblies;
- and
- friction members that are disposed at the ends of the rotating shaft assemblies, and grind the inside of the pipeline while contacting with the inside of the pipeline,
- wherein the rotating shaft assembly includes:
- a rotating shaft that is rotatably connected to the rotator assembly and rotates;
- a length adjusting shaft that is movably connected to the rotating shaft, rotated by a rotational force transmitted through the rotating shaft, and provided with the friction member at the end;
- and
- a shaft support spring that is connected to the rotating shaft and elastically supports the length adjusting shaft.
