Abstract
A motorized apparatus for use in maintaining a pipe includes at least one drive portion including a body assembly, a plurality of leg assemblies coupled circumferentially around the body assembly, a plurality of drive mechanisms coupled to the plurality of leg assemblies, and a drive portion coupling mechanism. The motorized apparatus also includes at least one maintenance portion including a body, at least one maintenance device coupled to the body, and a maintenance portion coupling mechanism configured to engage the drive portion coupling mechanism. The at least one drive portion is releasably coupled to the at least one maintenance portion by engaging the drive portion coupling mechanism with the maintenance portion coupling mechanism. The drive portion coupling mechanism and the maintenance portion coupling mechanism are each configured to engage another coupling mechanism when the drive portion coupling mechanism and the maintenance portion coupling mechanism are uncoupled from each other.
