摘要： PROBLEM TO BE SOLVED: To provide a thin tube maintenance and inspection apparatus which can improve working efficiency, can decrease the fatigue of a worker, can improve the work environment, has both a thin tube clamping function and a sealing function, and can carry out both the maintenance and inspection. SOLUTION: A plurality of cleaning guns are arranged on the same base plate, each cleaning gun being equipped with a gas/liquid pressure increase cylinder having a hollow piston rod. By the thrust force of the cylinder, a clamping collet attached to the tip of the piston rod is pressed via an elastic rubber arranged on the outer surface of the collet so that the outer surface of the rubber is pressed against the inner surface of a thin tube. Thus, the thin tube can be strongly fixed, the damage to the inner surface of the thin tube is prevented, and the leak of a cleaning liquid from the dividing plane of the clamping collet and from the contact section between the thin tube inner surface and the rubber to the thin tube opening side is prevented.

摘要： PROBLEM TO BE SOLVED: To safely maintain a large diameter bolt with excellent actuating efficiency by providing at least a pair of brushes which rotate in the mutually reverse direction and contact with different positions of the same bolt. SOLUTION: When a normally rotating brush 7 and a reversely rotating brush 8 are uniformly contacted with a bolt 9, since equal torques in the mutually inverse direction are applied to the bolt 9, the bolt 9 does not rotate. When the normally rotating brush 7 side is strongly pressed against the bolt 9, frictional force between the normally rotating brush 7 and the bolt 9 increases, and the bolt 8 reversely rotates. To the contrary, when the reversely rotating brush 8 is strongly pressed against the bolt 9, the bolt 9 normally rotates. When the normally rotating side is strongly pressed against it, maintenance is performed by the reversely rotating brush 8, and when the reversely rotating side is strongly pressed against it, the maintenance is performed by the normally rotating brush 7.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of chatter by fitting a cutting tool with a gradient to a rotating shaft of a cutting tool holder in such a manner that the tip edge position of the cutting tool is in the rear of the pressure receiving position of the cutting tool holder. SOLUTION: When a cutting tool holder 9 is rotated, a cutting tool 11 is elastically deformed backward, taking the pressure receiving position P2 of the cutting tool holder 9 as the center while cutting the cut surface. The cutting edge position Q2 of the cutting tool 11 is always in the rear of the pressure receiving position P2 of the cutting tool holder 9. Accordingly, even if the cutting tool 11 is returned to its initial attitude, only the force in the relief direction is always applied to the tip edge of the cutting tool 11. Accordingly, the cutting tool 11 is fluctuated in such a manner that the depth of bite of the tip edge is made smaller so as to reduce or prevent the occurrence of chatter.

摘要： PROBLEM TO BE SOLVED: To synchronously drive each independent control jack with each other even in the case of using plural independent control jacks by providing a booster, of which high-pressure side is connected to a hydraulic jack through a pipe and of which low-pressure side is connected to a hydraulic pump through a pair of pipes. SOLUTION: In a booster 4, an inner piston 7 is operated upward, and the oil, which is filled in a part P2 of a secondary side cylinder 6, is supplied as super high-pressure oil to a hydraulic jack 14 so as to project a piston 15. At this stage, the oil to be supplied to the hydraulic jack 14 is boosted up by the booster 4, and the supplied variable of the oil is accurately controlled. Furthermore, since quantity of the oil inside of the hydraulic jack 14 is controlled by the secondary side cylinder 6 and quantity of the oil of the secondary side cylinder 6 is accurately controlled by the fed variable of the oil of the hydraulic pump 2, lowering speed of the hydraulic jack 14 is accurately controlled. With this structure, even in the case of using plural independent control jacks, jack- down of the hydraulic jacks can be synchronized.

摘要： PROBLEM TO BE SOLVED: To dispense with fitting work to a back seat or to a guide plate and to shorten the time required for valve fitting work by rotating a roller through the driving of a power source via gear trains and by rotating a valve spindle installing frame, accompanying its up-and-down motion, via an annular cam with a wave form in the vertical direction. SOLUTION: In fitting a valve spindle 4, when a roller 11 stands on the bottom-position of a cam 12, a gap between a valve spindle operating bracket 9 and a valve spindle operating bracket receiver 9a is adjusted to an appropriate dimension first, and a compound is applied to a back seat receiver 3b and to a back seat 6. Next, a gap between a valve spindle operating bracket 9 installed in a gear 8 and a receiving seat 9a for the bracket 9 is adjusted so that the gap becomes 1 to 2mm, using adjusting bolts 23, 20. When the motor 5 is driven in this state, the valve spindle 4 is rotated, accompanying its up-and- down motion, via gears 7, 8, the operating bracket 9, an installing frame 10, and a valve spindle clamp 24, and fitting work can be conducted between the back seat 6 and the back-seat receiver 3b.
