Title: Drive method for cutter head
Inventor: MINAMI YOSHITO
IPC: E21D9/087
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency of excavation corresponding to the ground condition in a wide range by setting the basic frequency of an electric motor high in the case of excavation of a hard rock layer and setting it low in the case of the excavation of a weak layer, while inverter-controlling the motor. SOLUTION: For instance, a cutter head provided on a front side is rotated and driven by four high torque four-pole electric motors 4 attached to the supporter 2 of a cutter head drive part 1. High torque is obtained in a low rotation area by switching a basic frequency and lowering of the efficiency of output torque is prevented even in a high rotation area. As the result, the ground of the wide range of a weak layer to a hard rock layer is efficiently excavated by a rotating speed and torque corresponding to each ground quality condition. In addition, a low frequency lower than a commercial frequency is made the basic frequency, so that even when the electric motor of the small number of the poles is driven, the equivalent high torque as the electric motor of the large number of the poles can be obtained.  Thereby ground correspondence of a tunnel excavator used for the excavation of a hard rock part can be improved.
