摘要： PURPOSE: To measure and record bolt tightening operation automatically by measuring and recording tightening torque and a tightening time on the basis of a signal from a nut runner, by which tightening operation is conducted, and synthesizing tightening torque and the tightening time with operation reservation. CONSTITUTION: In a centralized controller 18, reservation data containing the place of operation, the order of operation, target torque, etc., by which tightening is conducted, are prepared, and transmitted to controller slave stations 17a, 17b. Tightening torque target values are transmitted to nut runner controllers 16a, 16b in each slave station 17a, 17b, and tightening torque at the time of tightening operation is measured and recorded. A bolt box 13 is rotated and tightening operation is performed when an operation switch 14 for nut runners 11a, 11b is depressed, and the revolution of the bolt box is stopped when a load current reaches a target value or more. When operators 11a, 11b depress a tightening completion switch 15, the maximum value of the current during a time when the switch 15 is pushed next is conserved as tightening torque, and measured data are prepared and transmitted to the centralized controller 18, and synthesized with the reservation data, thus preparing operation recording.

摘要： PURPOSE:To accurately and efficiently perform operations of extending a piping by allowing a dolly to travel forward in the direction of piping elongation until an end sensor senses the cut end of the already laid piping. CONSTITUTION:An expansion/contraction mechanism 3 is installed ahead of a dolly 2 which travels in the direction of pipe elongation. After separated from the already laid piping Pa, the mechanism 3 is shrunk, and meantime the dolly 2 is advanced in the direction of extending until and end sensor 7 senses the cut end of the old piping Pa. A new piping Pb prepared in the neighborhood of the connecting position is lifted by crane mechanisms 4, 4 down to the connecting position and held in the specified position by gripping mechanisms 5, 5. In this condition, connecting mechanisms 6, 6 are operated to connect the new piping Pb with the old piping Pa. This operating cycle is repeated, and the piping is extended into the specified length.

摘要： PURPOSE:To make a work easy and to promote efficiency by detecting displacement of an anvil against a casing in the case of striking, and controlling automatically the drop height of a ram based on the displacement. CONSTITUTION:When a pile 7 is struck by a ram 2 through an anvil 3, the pile 7 and anvil 3 instantaneously drop, and then a causing 1 is in a state of floating for a moment, but when a striker 11 provided to the anvil 3 reaches two detectors 10A and 10B on a mounting table 9 fixed to the casing 1, signals are detected. A ram height of next striking is automatically adjusted in accordance with the detected signals. In the case both of detectors 10A and 10B detect signals, the height of the ram is lowered one step, in the case both of detectors don't detector signals, by contraries, the height is raised one step, and in the case one of them only detects signals, the height of the ram is maintained.

摘要： PURPOSE:To allow even an operator with less experience to perform certain excavating operations easily and enhance the rate of service of an excavating machine by automating excavating operations among a series of operations with the machine. CONSTITUTION:An excavating machine control device includes a rotation sensor 17 for a winch in an excavating machine, a sensor 19 for the pressure of a hydraulic motor 16 to drive the winch, a sensor 20 to sense a bucket 6 at true top of a casing tube, and a calculator 22 to perform control calculation of the winch can the basis of signals from the sensors and a signal given by a setting device to set the excavation conditions. When the bucket is wound up or unwound down, the wire slackening amount at the time of bucket grounding and the bucket moving amount are sensed on the basis of the pressure of the hydraulic motor and the signal given by the winch rotation sensor, and thereupon start/stop of the winch and its speed are controlled. The winch brake signal output timing is controlled so that the wire slackening amount at the time of bucket grounding becomes appropriate from the wire slackening amount at the time of bucket grounding, max. speed of bucket fall, and the relation of the falling distance with the time in the event of falling.
