    Abstract: A boring machine comprises a forward section, a rear section, a parallel link mechanism, stroke sensors, pressure sensors, and a controller. The parallel link mechanism includes eight thrust jacks that change the position and attitude of the forward section with respect to the rear section. The controller computes a target allocation force to be allocated to eight thrust jacks on the basis of the sensing result from the stroke sensors and the pressure sensors, and controls the thrust jacks to perform stroke control on six of the thrust jacks and perform force control on two of the thrust jacks.

    Abstract: A boring machine comprises a forward section, a rear section, an articulation point, a parallel link mechanism, an input component, an articulation point position computer, and a jack controller. The parallel link mechanism includes a plurality of thrust jacks that change the position of the forward section with respect to the rear section. The articulation point position computer computes the position of the articulation point on the basis of the control inputs received by the input component, and the positions of the center line and center point of the rear section and the center point of the forward section. The jack controller controls the stroke amounts of the thrust jacks to produce movement corresponding to a curve generated from the positions of the center point of the rear section, the articulation point, and the center point of the forward section.

    Abstract: A drill bit exchange device for a shield tunneling machine includes: a housing with an aperture; a valve body housed in a chamber of the housing, the valve body being pivotable about a pivot axis (Ob) inclined at a predetermined angle with respect to an axis perpendicular to the front of a cutter head; a bit-housing hole formed in the valve body to detachably accommodate a bit; and an exchange seal part located at the front of the chamber and at a symmetrical position from the aperture with respect to the pivot axis (Ob). The valve body is pivoted about the pivot axis (Ob) to move the bit, which faces the aperture, to the exchange seal part, allowing the bit to be removed from the bit-housing hole and exchanged.

    Abstract: A tunnel boring machine (100) includes a cutterhead assembly (102) rotatably mounted to a forward shield assembly (116) through a cutterhead support assembly (110). The cutterhead support assembly is configured to receive a variable number of drive assemblies (105), such that the number of drive assemblies may be selected after fabricating the cutterhead support structure (120). The cutterhead support structure includes a housing portion (121) that houses the main bearing assembly (101) and a drive gear (104). A plurality of drive mount stations (111) provide access to the drive gear, and are provided with a pinion housing (130) for stations that receive a drive assembly, or with a cradle cover (140) for stations that do not receive a drive assembly.
