る。2. Description of the Related Art In a vehicle having a structure having an upper revolving structure 1 and a lower traveling structure 2, since the upper revolving structure 1 is capable of turning 360 degrees,
It is often used at construction sites with various working devices 3,
The driver 4 who has boarded the upper revolving unit 1 can operate the lower traveling unit 2 regardless of the turning position to move the vehicle. In the method of operating the vehicle, when the traveling wheel 6 of the lower traveling body 2 is behind, the driver 4 tilts the traveling lever 5 forward to move the vehicle forward. At this time, the oil pressurized by the pump flows through the forward pipe by moving the traveling lever 5 forward, and moves the hydraulic motor of the traveling wheel 6 in the forward direction via the rotary joint 8, and the vehicle Advance. This type of vehicle is not a work at a fixed position, but a work in which the working device 3 scoops the soil, turns and loads / turns on a dump or the like, and the movement always overlaps with the movement and the turning. During this operation, the driver 4 checks the position of the traveling wheel 6 of the lower traveling body 2 when moving, and instantaneously determines the moving direction of the vehicle and the moving direction of the operation lever. However, when the driver 4 is neglected, the direction in which the driver 4 faces may be illusioned as the forward direction of the machine, and the traveling lever 5 may be operated to move the machine. If the revolving superstructure 1 has turned more than 90 degrees, regardless of whether the driver is facing the reverse direction of the machine, the driver 4 mistakes the direction of his or herself as the forward direction of the machine, and If 5 is knocked forward, the machine will move forward and move in the direction of the driver 4's back. The machine moves in the direction opposite to the purpose of the driver 4, and comes into contact with surrounding workers, machines and the like, causing property damage and personal injury. Many accidents of this kind due to misjudgment of the turning position have occurred.

The information is transmitted to the turning position determination device 12, and when it is determined that the vehicle has turned more than a predetermined range, the direction control valve 13 is operated.
When an instruction to stop traveling is received, the flow of oil from the traveling lever to the traveling wheels 6 is shut off by the direction control valve 13, and the traveling lever 5 is stopped.
Becomes invalid. When receiving the instruction to reverse the oil flow, the direction control valve 13 causes the oil flowing from the traveling lever 5 to flow in the forward circuit to the reverse circuit. In addition, the oil that has flowed through the backward circuit is flown into the forward circuit. The oil passing through the directional control valve 13 flows through the rotary joint 8 to the traveling motor of the traveling wheel 6 to move the machine.

となる。The position information of the upper revolving unit 1 is transmitted from the turning position detecting device 11 to the turning position judging device 12, and when it is judged that the upper turning body 1 has turned more than a predetermined range, the direction switching valve 13 is operated. If the upper-part turning body 1 turns within a certain range,
The driver 4 is in the same direction as the traveling direction of the machine, and the direction switching valve 13 does not operate, so that the oil flows as in the related art. When the upper-part turning body 1 starts turning and turns over a certain range, the driver 4 faces backward, opposite to the traveling direction of the machine. 180
A typical turn is typical. In this position, the direction control valve 13 is operated by the operation of the turning position detecting device 11. At this time, if the traveling lever 5 is tilted with the direction in which the driver 4 is facing forward, the conventional machine moves in a direction backward with respect to the driver 4. However, in the present invention, the pressurized oil flows to the forward circuit by the traveling lever 5, and the flow is switched to the reverse circuit by the built-in directional control valve 13. This causes the traveling motor of the traveling wheel 6 to move backward and the machine to move backward.
When viewed from the driver 4, the operation lever 5 is moved forward.
This means that the machine has moved in the operation direction of. Upper revolving superstructure 1
When the lower traveling body 2 and the lower traveling body 2 are at an angle of about 90 degrees, the direction control valve 5 does not operate, so that the traveling is stopped. In this state, the upper swing body 1 can be moved by swinging in any direction.
