[0040]
The earth and sand transport device 1 is configured as described above, and is used as described below.
[0041]
First, the case where earth and sand are conveyed using the earth and sand conveyance apparatus 1 is demonstrated.
[0042]
(1) When the earth and sand transport device 1 is not in use, the transport vehicle 5 is stopped at a position approximately 2 m above the bottom of the excavation hole 3.
[0043]
(2) Next, when the operator continues to press the lower button of the remote controller, the transport vehicle 5 is lowered, and when the worker stops pressing the lower button of the remote controller, the transport vehicle 5 is stopped.
[0044]
(3) Next, the excavated earth and sand are loaded into the bucket body 37.
[0045]
(4) Next, the operator raises the transport vehicle 5 by pressing the ascent button of the remote controller.
[0046]
(5) As described above, when the transport vehicle 5 passes through the support frame 58, the bucket 6 automatically reverses and discharges the earth and sand.
[0047]
At that time, the bucket reversal detection sensor 36 detects that the bucket 6 has been reversed, and the transport vehicle 5 is automatically stopped.
[0048]
(6) After that, after a predetermined time has elapsed (for example, after 3 seconds), the transport vehicle 5 is automatically moved in the opposite direction to return the bucket 6 to the normal state.
[0049]
At this time, when the bucket reversal detection sensor 36 detects that the bucket 6 is still reversed without returning to the normal state, the transport vehicle 5 is stopped and a warning sound is generated. . On the other hand, when the bucket 6 has returned to the normal state, the transport vehicle 5 is lowered again and stopped at a position approximately 2 m above the bottom of the excavation hole 3.
[0050]
Next, the case where a person is conveyed using the earth and sand conveyance apparatus 1 is demonstrated.
[0051]
(1) Similarly to the above, when the earth and sand transport device 1 is not in use, the transport vehicle 5 is stopped at a position approximately 2 m above the bottom of the excavation hole 3.
[0052]
(2) Next, when the operator continues to press the lower button of the remote controller, the transport vehicle 5 is lowered, and when the worker stops pressing the lower button of the remote controller, the transport vehicle 5 is stopped.
[0053]
(3) Next, the operator changes the step 65 from the standing state to the lying state, and gets into the upper part of the step 65.
[0054]
At this time, if it is detected by the step storage detection sensor 68 that the step 65 is in a lying state, the transport vehicle 5 cannot be remotely operated by the remote controller and is provided in the drive vehicle 18. The operation vehicle 69 also prevents the transport vehicle 5 from being operated.
[0055]
Therefore, after the operator has stepped down step 65 and got on top of it, even if the external remote controller is operated by mistake or the operator's body accidentally touches the operation switch 69, The transport vehicle 5 does not rise or fall against the operator's will, and safety can be improved.
[0056]
(4) Next, the operator changes the protection bar 76 from the standing state to the lying state.
[0057]
At this time, if the protection bar storage detection sensor 70 detects that the protection bar 76 is in a lying state, the transport vehicle 5 can be operated only by the operation switch 69 provided on the drive vehicle 18. .
[0058]
Therefore, the transport vehicle 5 is raised or lowered only when the protective bar 76 is lying down to protect the body of the work vehicle, and this can also improve safety.
[0059]
(5) Next, when the operator continues to press the lift button of the operation switch 69, the transport vehicle 5 is raised, and when the worker stops pressing the lift button of the operation switch 69, the transport vehicle 5 is stopped. Let
[0060]
(6) Then, the operator raises the protection bar 76 from the lying state to the standing state, gets off the step 65, and changes the step 65 from the lying state to the standing state.
[0061]
As a result, the operation by the remote controller becomes possible again, and when the lowering button of the remote controller is pressed, the transport vehicle 5 is lowered again and stopped at a position about 2 m above the bottom of the excavation hole 3.
[0062]
