摘要： PROBLEM TO BE SOLVED: To reduce a diameter of a cylinder for operation and shorten stroke of a cylinder for grip by providing a cylinder which sandwiches a wire body which is stretched and provided by operating a clamp arm and another cylinder which grips a wire body which presses and sandwiches the clamp arm. SOLUTION: A link 7 approaches a wire receiver 5 by elongating a cylinder 8 having a small diameter and a wire grip part of a clamp arm 6 moves to just below the wire receiver 5 as the link 7 approaches to realize a stand-by condition in which a wire 3 is gripped. Next, the clamp arm 6 sandwiches the wire 3 with the wire receiver 5 by elongating a cylinder 9 having a large diameter based on the principle of lever by using the link 7 as a support point, thereby completing the grip of the wire 3.

摘要： PURPOSE:To improve workability by a method wherein a wheel arranged in a vertical communication ditch in the central part of a chassis is lowered as the wheel is rotated, a ground is excavated by buckets on the outer periphery of the wheel, and excavated soil is discharged to the side by a discharge chute. CONSTITUTION:When a wheel 4 is rotated by a motor 6 and the wheel 4 is lowered by a jack 5, a ground is excavated by buckets 7 and excavated soil is inputted in the buckets 7. When the bucket 7 is positioned above, soil in the bucket 7 is dropped under its own weight and fed through a hole part 4a to a discharge chute 8 and discharged to the side of a chassis 1. Discharged soil is accumulated in a hole part without being scattered. After excavation to a given depth is effected, working of the jack 5 is stopped. When the position of an arm 3 is fixed and a crawler 2 is driven, a chassis 1 is run to dig a ditch 103. In this case, since the bucket 7 is positioned at the central part of the chassis l, stable running is performed. This constitution facilitates formation of a uniform ditch even in a ground where excavation resistance is changed and improves the efficiency of excavation and discharge.

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.

摘要： PURPOSE: To improve the accuracy of measurement by mounting an encoder measuring the length of a detecting wire delivered when an excavator vertically digs successively, a laser displacement sensor detecting displacement from the vertical place of the wire and a computer processing these data. CONSTITUTION: A detecting wire 2 fitted to an excavator 1 is delivered in the progressive direction of the excavator 1 while the delivery length of the wire 2 is measured by an encoder 5. When the excavator 1 is displaced from a vertical place, the wire 2 is displaced in proportional to the quantity of displacement. Since places, where the wire 2 shields the luminous flux of laser displacement sensors 7, are changed at that time, the quantity of displacement in a horizontal surface of the wire 2 and the directions are measured. Verticality is arithmetically operated by a computer 8 from the quantity of the delivery of the wire 2 measured by the encoder 5 and quantity of displacement measured by the sensors 7, and the result of arithmetic operation is transmitted to the direction controller of the excavator 1. Accordingly, the accuracy of measurement can be improved without being subject to the effect of the vibrations, etc., of the excavator.
