MAINTENANCE SYSTEM FOR TUNNELIER AND ASSOCIATED TUNNELIER

摘要

This maintenance system (21), for a tunneling machine (1), comprises a garage (23) and a gripper (45), which comprises: - a base (47), through which the gripper is integrally linked to the garage, - a motorized kinematic chain (49, 55, 57, 71, 79, 83, 87, 89, 105), and - a gripping member of a tunneling wearer part connected to the base by the intermediate of the kinematic chain, the latter defining the position of the gripping member in space. The kinematic chain comprises at least one bent arm (89), a first pitch rotator which supports and drives the bent arm in rotation relative to the base (47), and a second pitch rotator which supports and rotates a front portion. of the kinematic chain that connects the crank arm to the gripping member.
