摘要： When a longitudinal straight traveling mode position A, an oblique traveling mode position B, a transverse traveling mode position C, or spin turning mode position D is selected by a traveling mode changeover switch 21, a signal corresponding to the selection is input to a controller 27. The controller outputs signals to turning actuators 15a and 15b for orienting driving wheels 11a and 11b toward the selected position. With this signal, the turning actuators 15a and 15b cause turning of the driving wheels 11a and 11b. At the same time, turning angle detection sensors 16a and 16b input signal indicative of turning angle of the driving wheels. When the turning angle becomes coincident with a preliminarily set angle, a signal for terminating turning is output to the turning actuators 15a and 15b. By this control, turning action of the turning actuators 15a and 15b is terminated with setting the driving wheels 11a and 11b at the position of the selected orientation.

摘要： The present invention is concerned with an apparatus for controlling a straight excavating operation with a hydraulic excavator such as a power shovel or the like machine including three working units, i.e., a boom, an arm and a bucket. When the straight excavating operation is performed, a hydraulic pressure of hydraulic oil in a hydraulic chamber on the boom lowering side of a boom cylinder is conducted to a drain tank while maintaining a predetermined set pressure, and a hydraulic pressure of hydraulic oil in a hydraulic chamber on the boom raising side of the boom cylinder is conducted to the drain tank via a check valve which serves to inhibit the hydraulic oil from flowing from the hydraulic chamber on the boom raising side of the boom cylinder to the drain tank, whereby the boom is held in the so-called floated state so as to enable a straight excavating operation to be performed merely by actuating the arm and bucket. In addition, according to the present invention, the apparatus is provided with an automatic bucket driving system for automatically controlling the present bucket angle so as to coincide with a preset bucket angle. This system contributes to remarkable reduction of a load to be borne by an operator while a straight excavating operation is performed.

摘要： Hydraulically-operated equipment such as travelling equipment or working equipment for use in construction machinery such as a power shovel, shoveldozer and bulldozer. The hydraulically-operated equipment comprises a hydraulic driving mechanism actuated by hydraulic pressure, a hydraulic pressure supplying device for supplying hydraulic pressure to a hydraulic pipeline system for the hydraulic driving mechanism and a controller for controlling the hydraulic pressure supplying device such that the supplying rate at which hydraulic pressure is supplied to the hydraulic pipeline system according to the supply of hydraulic pressure is decreased in a specified period after a dead zone period in which hydraulic pressure starts to rise. This arrangement prevents an operational lag in the hydraulic driving mechanism as well as a shock at the time of start-up and shut-down.

摘要： A teaching and playback method for a work machine that is applicable to construction equipment such as a hydraulic excavator to automatize operation. Data on the operator's operation of work machine actuators is stored, and the stored data is reproduced so that the same operation as that by the operator is automatically performed. The method is adapted to effect exactly the same operation as what has been taught even when, during playback, the load on the actuators has varied from the level applied during the teaching. For this purpose, the pump discharge amount and the amounts of flow supplied to the actuators which are present during the teaching are stored. During playback, when the load has varied, and the pump discharge has changed, the engine output is controlled in such a manner that the actual pump discharge becomes equal to the amount stored during the teaching. When the flows supplied to the actuators have changed, the flow control valve provided in an inflow circuit is controlled in such a manner that the actual flows become equal to the amounts stored during the teaching. Thus, even when the load during playback has varied from the level during the teaching, the actuators can operate exactly as taught, without involving a discrepancy in the locus of operation.

摘要： A hydraulic apparatus for a construction machine, which is adapted to prevent the number of revolutions of an engine from increasing when the flow of the fluid discharged by a variable displacement hydraulic pump driven by the engine is cut off. The hydraulic apparatus comprises a proportional solenoid (11) connected to a fuel supply control lever (13) so as to vary the horsepower characteristics of the engine, which are set by the action of a governor (12) based on manipulated variable of the fuel supply control lever (13) when the flow of the fluid discharged by said pump is cut off, and a controller (10) for controlling the proportional solenoid (11). In this apparatus, a decrement (.DELTA.Nr) in a target number of revolutions per minute (Nr) of the engine, which can be obtained by subtracting a target number of revolutions per minute (Nrb) of the engine at the desired engine horsepower characteristics (l.sub.2) from a target number of revolutions per minute (Nra) at the initial engine horsepower characteristics (l.sub.1) is computed, and said proportional solenoid (11) is operated in accordance with this decrement.

摘要： An operator's actions for achieving a desired operation of a machine's actuator can be memorized in a teaching mode and the memorized information can be used for automatically reproducing the desired operation in a play back mode, to alleviate the operator's burden. A failure in the play back mode caused by the difference in the conditions under which the play back mode and the teaching mode are conducted can be eliminated, and the operation can be allowed to be continued in the manual mode even if a failure occurs in an automated operation control system. In order to achieve these, when a correction operation by the operator is detected in the play back mode, the play back mode is interrupted and the correction operation is processed with priority to the play back operation. Such correction operation is implemented by a correction signal priority circuit provided on a signal path from a signal converting device for converting the operator's operation into an electrical signal and an electronic controller for interrupting reading-out of the teaching operation data from the memory and for inputting the operator's operation to the electronic controller.

摘要： A service valve circuit of a hydraulic excavator connected beforehand for use in controlling a special attachment in addition to a prescribed actuator control valve. The service valve circuit comprises a confluence valve 17 for performing electromagnetic proportional flow rate control, disposed in a confluence circuit 16 in communication with the section between inflow circuits 3F and 3R of two variable pumps 2F and 2R, an electrical switch 21 for switching the confluence valve 17 on or off according to a required flow rate and a volume 22 for adjusting the quantity of flow after passing through a confluence valve 17 in a range of flow for a maximum of one to two pumps. Since the requirement of confluence with respect to a required quantity of flow for a special attachment e and the quantity of confluence are set in advance, there will be no excess or shortage of the quantity of confluence. Therefore, the adjustment of flow rate using the number of rotations of an engine is not required and the action will not be slowed down even if switched from a special attachment control to a pivoting or traveling control.
