  • DEVICE TO INSERT A FLEXIBLE MEMBER INTO PRESSURIZED WELLHEAD HOUSING
    Publication number: 20100018721
    Abstract: A drive assembly for inserting hose within a wellhead housing that intermittently reciprocates the hose feed into the housing. The intermittent reciprocating action feeds the hose past obstacles in the wellhead housing, such as within annuluses between tubulars. The drive assembly includes rollers that frictionally contact the hose and when rotated drive the hose forward. The rollers are rotated by a drive sprocket that is rotated by a hand crank. An offset cam assembly between the hand crank and the drive sprocket adds an orbital/reciprocating motion to the drive assembly.
