The container 3 is unloaded between the container carrier 1 and the container carrier by lifting and moving the container 3 using a crane.

Next, in the case where the waste stored in a certain garbage storage site is transferred to a final disposal site or the like using the container 3 configured as described above, for example, the opening and closing which is a main part of the present invention is performed. A description will be given together with the opening and closing operation of the lid 43.

First, the open / close lid 43 of the container 3 placed on the container transport vehicle 1 is opened, and the waste in the garbage storage is stored through the input port 41.

More specifically, by operating the open switch of the operation section 75, the control device 9 first switches the first switching valve 81 from the neutral position to the right position, and retracts the securing cylinder 69. As a result, each lock device 6 is rotated by the interlocking mechanism 65 from the securing position shown in FIG. 5 to the release position shown in FIG. When each lock device 6 is arranged at the release position in this way, the release detection sensor 72
The controller 9 switches the first switching valve 81 to the neutral position and switches the second switching valve 82 from the neutral position to the left position based on the detection signal. Thereby, the opening / closing cylinder 52 is extended, and the opening / closing lid 43 is arranged at the open position as shown by a two-dot chain line in FIG. 4, and the charging port 41 is opened. Control device 9
, A detection signal is input from the opening detection sensor 73 to detect that the opening / closing lid 43 is normally arranged at the opening position.

Therefore, by putting waste into the container 3 through the inlet 41, the waste can be stored in the container 3. When the storage of the waste is completed, the open / close lid 43 is closed, and the open / close lid 43 is closed.
Is secured by each locking device 6.

More specifically, by operating the closing switch of the operating section 75, the control device 9 first switches the second switching valve 82 from the neutral position to the right position, and retracts the open / close cylinder 52. Thereby, the opening / closing cylinder 52 is contracted and the opening / closing lid 43 is arranged at the closing position as shown in FIG. When the inlet 41 is closed by the opening / closing lid 43 in this manner, a detection signal is input from the closing detection sensor 74 to the control device 9, and the control device 9 sets the second switching valve 82 to the neutral position based on the detection signal. And the first switching valve 81 is switched from the neutral position to the left position. As a result, the securing cylinder 69 extends to move each lock device 6 from the release position to the securing position, and firmly secures the open / close lid 43 in the closed state. At this time, the control device 9
A detection signal is input from the securing detection sensor 71 to detect that the lock device 6 has been normally placed at the securing position.

As described above, by controlling the expansion and contraction operation of the opening / closing cylinder 52 and the securing cylinder 69 by the control device 9 based on the detection signals of the respective detection sensors 71 to 74, the opening / closing cylinder 52 is reliably connected to the opening / closing cylinder 52 in the above-described procedure. The lashing cylinder 69 can be operated. Thereby, for example, the opening operation of the opening / closing lid 43 in a state where the locking device 6 does not release the locking is restricted, and the closing operation of the opening / closing lid 43 in a state where the locking device 6 is arranged at the locking position is performed. Therefore, accidents such as damage to each member caused by these can be reliably prevented.

Further, by closing the opening / closing cover 43 and securing it with a plurality of lock devices 6, the opening 41 can be tightly closed in an airtight state by the opening / closing cover 43 via the packing 44. For this reason, it is possible to reliably prevent the stored waste and the waste liquid of the waste from leaking outside during transportation, which is suitable for transporting dangerous industrial waste and the like.

Then, the container 3 containing the waste is transported to the port where the container carrier is anchored by the container transport vehicle 1, and the container 3 is transferred from the container transport vehicle 1 to the container transport vehicle by a crane. Transport to the nearest port of At the port, the container 3 is reloaded from the container carrier to the container transport vehicle 1 by a crane, and the container 3 is transported to the final disposal site by the container transport vehicle 1.

When the container 3 is transported as described above, since the inside of the container 3 is closed in a closed state by the opening / closing lid 43 and the discharge gate 45, the waste or odor inside does not leak to the outside. , The watertightness is ensured, so that no waste liquid etc. leaks out,
It can be transported hygienically without adversely affecting the surrounding environment.

When the waste in the container 3 is discharged, the container 3 is placed on the vehicle frame 11 via the tilting frame 2 and the discharge gate 45 is released.
By tilting the tilt frame 2 about the rear hinge 21,
The container 3 is tilted together with the tilting frame 2 as shown by a two-dot chain line in FIG. As a result, the discharge gate 45 opens downward around the upper hinge 46, and the waste inside is discharged from the discharge port 42 opened by the downward opening.

In the garbage storage site where waste is carried out,
Since there is no work to discharge waste by the container transport vehicle 1, the container transport vehicle 1 used in this garbage storage site
It is not always necessary to provide a mechanism for tilting the container 3.

[0043]

As described above, according to the waste transporting container of the present invention, the open / close lid closed via the sealing mechanism is secured by a plurality of lock devices, so that the lid is closed inside during transport. The stored waste and its waste do not leak to the outside and can be transported hygienically without adversely affecting the surrounding environment, especially for transporting dangerous industrial waste. It is suitable. In addition, by controlling the operation of the first actuator and the second actuator by the control device based on the detection of each detection sensor, a series of operations of securing and releasing the opening / closing lid and opening / closing can be performed smoothly and reliably. It is possible to prevent accidents such as damage to the lock device and the opening / closing lid due to erroneous operation.
