摘要： PROBLEM TO BE SOLVED: To simplify the structure, miniaturize the size, reduce the cost of an erector controller by enabling the erector controller to position protective segments accurately using a simple structure, and to improve assembly workability in implementing an assembly method for lining members using an erector controller. SOLUTION: Distances from ultrasonic sensors 41-44 to gripped segments S H and lined segments S F are measured as the sensors are swung. The measured swing angles θ 1 , θ 2 , θ 3 , θ 4 and distances L 1 , L 2 , L 3 , L 4 of respective sensors 41-44 are used by a level difference calculating section 52 to calculate respective vertical heights H 1 , H 2 of the segments S F , S H and a difference between both vertical heights to compute a level difference H between both segments, while a gap calculating section 53, using the above measurement, calculates respective gaps S 1 , S 2 of the segments S F , S H and the sum of both gaps to compute a gap S between both segments. The controller 20 drives and controls the erector 11 so as to reduce the level difference H and the gap S, moving the gripped segment S H to a prescribed position. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a cutter rotation controller for a shield excavator capable of eliminating troubles occurred in the conventional controller, such as a decrease in the rated load of a motor and a lowered power factor after the steady-state rotation of the conventional cutter head thereby making the driving electric power wasteful. SOLUTION: This cutter rotation controller detects the loads and power factors of a plurality of cutter turning motors performing the excavation of the ground; by these detected values, the cutter turning motors are set to a number of units performing the ground excavation at a state of 100% rated load, thereby improving the power factor of motors for the operation. In the case of cutter turning motor, a load per one unit decreases during the steady- state operation of the cutter head, the power factor of motor drops, the efficiency of operation drops relative to the power supply, the number of units is selected based on the detected values of the load and power factor of the cutter turning motor detected by wattmeter; the operation can be performed by setting the motor load and power factor of the cutter turning motor almost to 100%; and by rotating the cutter head and improving the operating efficiency with a small power supply for the ground excavation.

SOLUTION: A cutter head 12 is rotatably mounted to the front of a skin plate and a mount seat 32 is mounted to cutter spokes 13 radially fixed to the front of the cutter head 12 through a supporting axis 31 so as to be swingable forward and rearward in the excavation direction. A cutter bit 14 is mounted to the seat 32 through a bolt 33 so as to be turned between a projecting position and a replacing position. On the other hand, a fixing plate 35 holding the bit 14 at its projecting position is secured to the spokes 13 through a bolt 34 to fix the bit 14 at the projecting position.

摘要： PURPOSE:To improve safety and shorten construction time by measuring the distance between a shield excavator body and the reference face of a fixed point in the body, and the distance between the reference face and a segment so as to automate the measurement of a tail clearance. CONSTITUTION:The body distance L2 from the reference face P of a fixed point in the shield excavator main body 1 to the inner peripheral surface of the main body 1 is measured by a body distance sensor 2. The segment distance L3 from the reference face P to the inner peripheral surface of a segment 3 is then measured by a segment distance sensor 4 to obtain a tail clearance L1. As occasion calls, both distance sensors 2, 4 are moved in the axial direction of the segment 3 by slide mechanism 5. At the measuring time, the segment distance sensor 4 and the segment 3 are always opposed to each other, and at the non-measuring time, both sensors 2, 4 are accommodated in the shield excavator main body 1 to take refuge. With the adoption of two distance sensors 2, 4 and the slide mechanism 5, the reliability and reproducibility of the measured value can be improved.

摘要： PROBLEM TO BE SOLVED: To securely assemble retaining lining members in a correct position by appropriately detecting the position or the posture of existing lining members in the assembling method for the erector controller and the lining member. SOLUTION: Distance sensors 46a-46f, 47a-47i measuring the height up to segments S H ,S F and edge detection sensors 48a-48e detecting the joint of adjacent segments S H ,S F are provided. A first precise positioning means 52 calculates the level difference and gap between an existing segment S F and the holding segment S H and the controller 20 decides the first precise position of the holding segment S H so that the level difference and the gap decrease. Next, the second precise positioning means 53 estimates an assembling position and a posture where the bolt hole positions of the holding segment S H is correct against the bolt hole position of the existing segment S F . The controller 20 corrects the position and the posture of the holding segment S H whose first precise position is decided. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To facilitate the exchange of cutter bits when the cutter bit is worn by rotating a cutter bit holder provided with a plurality of cutter bits to evacuate a front cutter bit into a mounting groove, and advancing the cutter bit in the groove to the front. SOLUTION: A plurality of cutter spokes 13 are radially attached to a cutter head, and mounting grooves 13a are provided at a predetermined interval in the radial direction. A rotary shaft 31 is provided by directing a shaft center to the longitudinal direction of the cutter spoke 13 so as to rotate freely, and the rotary shaft 31 is exposed from the inside of the cutter spoke 13 in a mounting groove 13a part. A cutter bit holder 32 rotates integrally with the rotary shaft 31. A cutter bit and a preceding bit 33 bring one of them to the front of the cutter spoke 13 and evacuate the other into the mounting groove 13a due to the rotation of the cutter holder 32. While a tunnel is digged, the cutter bit holder 32 is rotated to exchange the worn cutter bit 14 with a new cutter bit 14 when the cutter bit 14 is worn, thereby facilitating the exchange work.
