ABSTRACT:
A cart for inspecting a drill pipe having a platform with an ultrasonic inspection unit thereon, a first pair of wheels connected to the platform so as to move the platform longitudinally along the drill pipe relative to a rotation of the drill pipe, and a bearing connected to the platform at a location distal of the first pair of wheels. The bearing serves to support the platform above an adjacent drill pipe and allows the platform to move longitudinally along the adjacent drill pipe in correspondence with the movement of the first pair of wheels. The first pair of wheels are canted at an angle relative to the longitudinal axis of the drill pipe. A sensor wheel extends outwardly of the platform and rotates during the movement of the platform along the drill pipe. The platform has at least one handle extending upwardly from the platform. The bearing includes a pair of rollers that have an axis of rotation which is transverse to the longitudinal axis of the adjacent drill pipe.
