Abstract

PURPOSE:To raise safeness of an earthwork vehile when an operater becomes faint as well as make easier the backward and forward operations of the vehicle by remote control by using a system in which when an operation controller is actuated to make a transmission neutral, a service brake controller is automatically operated. CONSTITUTION:An earthwork vehicle 2, e.g., loader, etc., has a body 4 to be connected in a turnable manner through a connecting pin 10 at its front part 6 and its rear part 8, and the vehicle 2 is also provided with a service brake controller 20 to prevent the moving of the body 4 and a parking brake controller 22. The running and operation of the earthwork vehicle 2 are controlled by remote control. When a transmission is made neutral by an operation control signal, the service brake controller 20 is put into an operation condition. Only by operating the operation lever 28, the forward and backward operation of the earthwork vehicle body 4 can be switched, and even when an operator becomes faint, the operation lever 28 can be automatically set to neutral to prevent the movement of the vehicle body 4.

The transmission control device 24 includes a steering control means, a service brake actuation means, a parking brake actuation means, and an emergency stop actuation means. The operation control means is an operation lever 28f provided on the upper surface of the control device main body 26 so as to be tiltable in any direction.
: Contains. In such a steering control means, the operating lever 28 is placed in a neutral position (the position shown in FIGS. 2-A and 2-B, and when it is moved to this position, it becomes 0 neutral).
When tilted forward (upward in Figure 2-B) from the state of ``forward'', the forward signal becomes rLJ
When the control lever 28 is tilted backward (downward in Figure 2-B) from the neutral position to rHJ, the reverse signal changes from rLJ to rHJ, and the control lever 28 is moved backward (downward in Figure 2-B). When tilting from the neutral position to the right (to the right in Figure 2-B), the state of "right steering" occurs, and the right steering signal changes from r L J to r H J VC, and the operation leno (-28 full To the left from the neutral position (2nd-B)
When the steering wheel is tilted to the left (in the figure), it enters a "left steering" state and the left steering signal changes from r L J to r HJ. Furthermore, if the operation 1/bar 28 is tilted forward from the neutral position and then further tilted to the right (or left), the state is 0 forward right steering' (or forward pressure steering). The forward signal and right steering signal (or left steering signal) change from rLJ to I'
If you tilt it backwards from the above neutral position and then further tilt it to the right (or left), it will be in the state of 1 reverse right steering'' (or 6 reverse left steering). When the reverse signal and right steering signal (the left steering signal for me) are ““
"L" becomes "HJ."Furthermore, if the operating lever 28 is tilted to the right from the above-mentioned neutral position and then further tilted forward (or rear') 5), "forward right edge direction" (or single right steering The right steering signal and the forward signal (or reverse signal) change from rLJ to rHJ, and after tilting the operating lever 28 to the left from the neutral position, the steering wheel moves further forward (or backward). When tilted to ``forward pressure steering'' (or
Then, the left steering signal and forward signal (or reverse signal) change from rLJ to rHJ.

4, the emergency stop signal of the output signal rLJ is sent from the emergency stop signal 24 of the output signal rLJ to the NOT gate N0Tl and ORI, and from this NOTI, the signal of the output signal rHJ is further sent to the AND gate AND4 (
It is also sent to 1-LAND5). Therefore, when the rHJ forward signal (or backward signal) is sent to the AND gate AN
The output signal of D4 (or AND5) becomes rHJ, and the output signal r of this AND gate AND4 (or AND5)
Due to HJ, the transmitusiran 36 moves forward (or backward). Also, when the rHJ forward signal (or reverse signal) is sent to the Noah gate N0RI, the Noah game)
The output signal of NORI becomes rLJ, [this Noah game]

The output signal of RI becomes rLJ. In addition, the above Noah game) N
The rLJ output signal from the ORI is sent from the transmission control device 24 to the OR2 (to which the service brake signal of the output signal rLJ (because the automatic return type suppression switch 34 is not pressed) is sent), and this Or game) O
The output signal rLJ of R2 is sent to the AND gate AND3, and the output signal of AND3 becomes rLJ,
Due to the output signal [LJ of the AND gate AND3, the service brake braking device becomes inoperative. In this way, the earthmoving vehicle main body 4 is moved forward (or backward).

Further, the operation lever 28 is tilted as described above to move the steering control means (therefore, the transmission control device 24) one step forward and to the right.
Or, if the state is "forward left steering" (or 0 reverse right steering) or "reverse left steering", the forward signal (or reverse signal) and right steering signal or left steering signal are activated as described above. The signal is “H”
”. Therefore, in such a case, the vehicle main body 4 is steered toward the forward right edge or forward left edge (or toward the backward right edge or backward left edge), as can be easily understood from the above description. In this case, the service brake system ft20 is inactive due to the forward signal (or reverse signal) of "■(").

As described above, in the above-mentioned Sat=E vehicle 2, the transmission 36 is set to neutral V by the steering control means (in other words, the state of the transmission control device 20 is set to "neutral"). When the service brake braking device 20 is in the operating state, the earthmoving vehicle main body 4 is activated.
is forced to use the Zarbis brake. Therefore, when switching the earthmoving vehicle body 4 from forward to reverse or from reverse to forward, there is no need to press the suppression switch 34 as in the conventional case.
It is sufficient to simply tilt the entire operating lever 28 downward, which greatly simplifies the operation. Furthermore, even if the operator is in a state of fainting (Cnatsuf?), the control lever 28 is automatically placed in the neutral position and is in the "neutral" state, so that the driver and brake braking device 20 are not activated. As a result, the movement of the earthmoving vehicle body 4 can be completely prevented, making it extremely efficient from a safety standpoint.
