摘要： A drilling machine for a railroad rail, in which the railroad rail is clamped crosswise with respect to a main body case by a catch frame and a clamp arm, includes a cutter advanced perpendicularly with respect to the middle part of the rail by turning the rotating handle of a link mechanism to drill boltholes is specific positions. The drilling position of the bolthole to be drilled in the middle part of the rail is set by a height gauge, secured on the catch frame, and a pitch gauge, mounted on the railroad rail.

摘要： A cutting machine for a railroad rail performs clamping by use of a screw to fasten a catch arm onto a gauge which indicates a cutting position and is fastened onto a railroad rail. The catch frame is connected to a main body block via slide shafts, and a rotating grinding disk saw, driven by an engine mounted on the main body block, is rocked by working a stroke handle to smoothly raise and lower the rotating grinding disk saw within a cut opening to cut the railroad rail crosswise. By varying the cut of the rotating grinding disk saw, frictional resistance to cutting is reduced and the generation of frictional heat is prevented, permitting use of a small-scale engine and improving the accuracy of the cut.

摘要： The present invention provides an impact wrench and a bolt-tightening method such that a spring force is applied, through the circumference of a spindle coupled with the output shaft of an electric motor, in the forward direction to a hammer which is capable of forward and rearward movement and rotational motion following the spindle. The hammer and an impact shaft are brought in coaxial mesh alignment by leaving a gap between them in the direction of rotation so that when a bolt to be tightened is inserted into a socket fixed to an end of the impact shaft to permit the bolt to be tightened, the mesh contact with the impact shaft is released as a result of the hammer being lifted up in the rearward direction against the reaction force due to the tightening of the bolt. An impact sensor detects release of the hammer from the impact shaft and an angle sensor measures the angle of rotation of the impact shaft. This permits measurement of the torque of the impact shaft by measuring the amount by which the angle of rotation of the impact shaft advances each time the impact force is generated. The amount by which the angle of rotation of the impact shaft advances from the time at which the measured torque has reached the previously set snug torque value can also be measured so that the power supply to the electric motor is disconnected when the amount of advancement of the rotational angle has reached a pre-defined value of the preset angle of rotation to stop the rotation of the impact shaft through a braking circuit.
