This invention relates to the field of intelligent machinery, and more particularly to a
robot for inspecting and repairing small- and medium-
diameter pipelines. The
robot includes: an inspection and repair module connected to a carrier plate, the carrier plate being mounted on top of a worm gear seat; a central
drive motor with an output shaft at each end, a central
bevel gear fixed on the output shaft, and four equally spaced subsidiary bevel gears meshing with the central
bevel gear along its circumference; each subsidiary
bevel gear being coaxially connected to a worm; a worm wheel and a driving synchronous
pulley meshing with the worm; one end of the worm gear seat being connected to a subsidiary plate, and the other end enabling the connection and rotation of the worm wheel, the driving synchronous
pulley, and the traveling
rocker arm; the driving synchronous
pulley and the driven synchronous pulley at the end of the traveling
rocker arm being connected via a synchronous
toothed belt; the driven synchronous pulley and the traveling wheel being coaxially and tightly fitted; and a
torsion spring fitted at the end of the traveling
rocker arm. The
robot of this invention exhibits strong
vertical climbing ability, bend-crossing ability, and dynamic adaptability to different pipeline diameters.
