The operation of the operating device, which is another operating device for electrically operating the operating lever of the embodiment, will be described with reference to the wiring diagram of the electric circuit shown in FIG. For convenience of operation explanation, when operating the operating lever for starting,
It is called a start lever, and when operated to stop, the expression stop lever is used. Therefore, the operating lever uses the expressions of the start lever and the stop lever. (1) Initial operation When the main switch is turned off during the operation of the electric cylinder, the stroke position of the electric cylinder is arbitrary, so by turning on (turning on) the main switch, both for starting and stopping. The cylinder waits in the retracted position. (Explanation of operation) When the starting lever 3 is at the stop position and the main switch is turned on for one stage, the IG circuit is connected, and no electricity is flowing through the relay R3 coil of the starting lever portion. Therefore,
Electricity flows from the B contact to the relay R3 of both the start button system and the stop button system, and the relay R1 coil and the relay R2 coil are energized, and both form a self-holding circuit. When the relay R1 coil is excited, the relay R1A contact is connected, and the starting electric cylinder 24 moves to the contraction side and stands by. By exciting the relay R2 coil, the relay R2A contact is connected, and the stop electric cylinder 8 is
Move to the shrink side and wait. Since both sides are on standby on the contraction side, starting and stopping operations can be performed manually, which gives priority to manual operation and is safe. (2) Start operation By pressing the start button, the stroke of the start electric cylinder 24 is extended, the start levers 3 and 25 are moved to the start position, and then the start lever is contracted again and stands by. (Description of operation) When the start button of the start button system is pressed while the self-holding circuit is formed on the contraction side and waiting by the initial operation, the electric circuit is cut off, and at the same time the self-holding is released, so the relay R1B contact The circuit is switched to the side, the electric cylinder 24 moves in the extension direction, and the lever pin 4 that is interlocked with the starting lever 3 is pushed to bring it to the starting position.
The machine is in a running state. At this time, the electric cylinder 24 is
Operate the return limit switch at the fully extended position. By turning on the return limit switch,
Once again, the start button system self-holding circuit becomes the standby state on the contracted side, and the state becomes the same as the initial operation. (3) Stopping operation By pressing the stop button, the starting lever 3 of the electric stopping cylinder 8 is pushed back to the stop position, and then contracted again and stands by. (Description of operation) A self-holding circuit is formed on the contracted side in the initial operation, and when the machine is in the running state while waiting, pressing the stop button shuts off the electric circuit, and at the same time self-holding can be released. , The circuit is switched to the relay R2B contact side, the electric cylinder 8 moves in the extension direction, and the lever pin 4 interlocked with the starting lever 3 is pushed to the stop position, so that the machine stops. At this time, the electric cylinder 8 operates the return limit switch at the fully extended position. When the return limit switch is turned on, the stop button system becomes a self-holding circuit again, and the contraction side enters the standby state.
By providing a plurality of switches in the stop button system circuit, it is easy to add a safety device such as a bumper stop or an emergency stop.

[0022]

According to the present invention, since the operation levers provided on the power vehicle are provided on the left and right sides of the towing vehicle which is the power vehicle, the operation can be performed from both the left and right sides of the rail, so that the operation on the truck is
You can easily operate the lever regardless of the course.

Even in unmanned transportation, the operator can stop the carrier regardless of the left or right side of the rail.
Safety is improved because there is no dangerous activity on slopes such as traversing rails.

Since the trolley is provided with another manual lever in which a push / pull wire is connected to the operation lever provided on the towing vehicle, starting and stopping operations can be easily performed from the top of the trolley. The push-pull wire that connects the operation lever provided on the towing vehicle and the manual lever provided on the trolley can be operated in the pushing direction and pulling direction even if the position of the power vehicle and the trolley changes due to the curve of the track. It transfers the load and does not impair its function. Thus, for example, when the manual lever is stopped from the cart, the power transmission of the power vehicle is released by the push-pull wire, and the stop brake of the power vehicle is activated. Further, since the operation lever is provided with a cam, the stop position is detected and the stop brake of the truck is operated. For this reason, a stop position detection switch is provided which is operated by being pushed by the same cam. The stop position detection switch is pushed by the cam of the operation lever of the motor vehicle, the release current of the electromagnetic brake of the truck is cut off, and the truck brake is activated.

In the operation by the operation box, when the start switch is pressed, a relay current flows through the electric cylinder, and this cylinder pushes the lever operation arm (front) in the start direction to
After the operating lever is in the starting position, the cylinder is contracted to return the lever operating arm (front) to the original position and wait. The lever operation arm (rear) is also controlled to perform the same operation.

Therefore, after the operation lever is electrically operated, the manual operation is prioritized from the start to the stop position operation or from the stop position to the start operation.

Even if the electric system fails, the lever operation arms (front) (rear) can be manually operated because the cylinders are stopped at the positions where the cylinders are contracted.

From the above, it is possible to operate two systems, this and electric operation, while giving priority to the operation of a plurality of levers.
Even if there is a failure in the electrical system, the function will be fulfilled by manual operation, and an efficient carrier can be provided. The operation lever itself of the motor vehicle can be operated by operating the manual lever of the truck or the button on the operation panel. Therefore,
Without releasing the power and stopping the engine, the cams are actuated by the operation of the operating lever to brake and brake, and safe and comfortable driving operation is possible without impact at the time of stop.
