The invention relates to an inspection well repairing
machine, in particular to a spherical inspection well repairing
machine. The spherical inspection well repairing
machine comprises a dragging device and a working device; the working device comprises a skeleton structure, a
fuel oil engine, a
power control device, a saw blade device, a rotary rolling disc device and a hydraulic device; the skeleton structure comprises a
chassis, a rotary rolling disc, a rotary disc, a horizontal moving support, a vertical moving support, a wheel lifting rack, wheels, a support, a water tank, a lifting guide rail and an engine cover; the
power control device comprises a PLC, a rotary rolling disc driving
hydraulic motor, an accelerator driving motor, a hydraulic lifter and a storage battery. According to the spherical inspection well repairing machine, a hydraulic
power station is arranged, the size of the
cutting circumference can be adjusted, and therefore the spherical inspection well repairing machine can meet the
cutting requirements with various sizes; in addition, a circumferential groove
cut by a spherical arc-shaped saw blade is shaped like a big-end-up pan bottom, a repaired base body is not liable to sink through the interaction force between an entirety formed by filled auxiliary materials and the machine, and then the repairing quality is improved.
