Abstract: The feeding device in ZDY1450LG all-hydraulic tunnel drilling rig was designed. The device uses double-rod and double-action with two extension cylinder, increasing the feeding stroke, saving auxiliary time and decreasing overall dimension of drilling rig. The stress and strain of double-rod and double-action with two extension cylinder are analyzed with the finite analysis software ABAQUS in the state of feed and draw force. The reliability design of feeding device was realized to provide a base for the design of feeding system. It also provided a reference for the design of feeding device in other type drilling rigs.
