Then, by supplying the compressed gas discharged from the gas compressor 7 into the container 1 to be inspected through the gas hose 9B, the pressure in the container 1 to be inspected is increased to generate a pressure difference between the container 1 and the alternative container 2. The pressure difference causes the liquefied gas in the container 1 to be inspected to pass through the liquid hoses 10B and 10A.
And transferred into the alternative container 2. When the transfer operation of the liquefied gas is completed, the gas hoses 9A, 9B and the like are detached from the substitute container 2, the container 1 to be inspected, and the gas compressor 7, and are withdrawn.

Hereinafter, a method for inspecting a liquefied gas filled container using the exchange vehicle 11 will be described. In the present inspection method, the same components as those in the above-described conventional inspection method are denoted by the same reference numerals, and description thereof will be omitted.

First, when the owner of the container 1 to be inspected requests re-inspection, in the alternative container transporting step shown in FIG. A replacement vehicle 11 having the replacement container 2 to be mounted on the carrier 14 is dispatched, and the replacement vehicle 11
The alternative container 2 is transported to the vicinity of the container 1 to be inspected installed in the container.

Next, in the first liquefied gas transfer step shown in FIGS. 5 and 6, the liquefied gas remaining in the container 1 to be inspected is transferred into the substitute container 2 using the gas compressor 22 as described below.

First, only the alternative container 2 mounted on the carrier 14 is transferred to the vicinity of the consuming facility A by using the crane 32. In this case, since the crane 32 is disposed on the rear side of the vehicle body 13, even if the crane 32 turns while the alternative container 2 is suspended, for example, the alternative container 2
2. It can prevent interference with the gas compressor 22 etc.

Further, by keeping the gas compressor 22 mounted on the loading platform 14, the operation of transferring the gas compressor 22 between the loading platform 14 and the consuming facility A can be omitted.

Next, the gas hoses 29A and 29B and the liquid hoses 31A and 31 stored in the hose storage 19 are shown.
B is taken out from the hose storage 19. Then, as shown in FIG. 3, the distal end of the gas hose 29A is connected to the vapor discharge pipe 30A of the alternative container 2, and the distal end of the gas hose 29B is connected to the vapor discharge pipe 30B of the container 1 to be inspected. The distal end of the liquid hose 31A is connected to the liquefied gas introducing pipe 32A of the alternative container 2, and the distal end of the liquid hose 31B is connected to the liquefied gas introducing pipe 32B of the container 1 to be inspected.

In this case, the gas hoses 29A, 29B,
Since the base ends of the liquid hoses 31A and 31B are always connected to the gas compressor 22 fixed on the carrier 14, the distal ends of the gas hoses 29A and 29B and the liquid hoses 31A and 31B are used as substitute containers. 2 and the container 1 to be inspected, the gas compressor 22 can be quickly connected to the alternative container 2 and the container 1 to be inspected.

In this manner, the gas hose 2 is connected between the gas compressor 22 and the alternative container 2 and the container 1 to be inspected.

After being introduced into the inspection container 1, the pressure in the container 1 to be inspected rises and a pressure difference is generated between the container 1 and the alternative container 2.

Thus, the liquefied gas G in the container 1 to be inspected is
However, the liquefied gas introduction pipe 32B, the liquid hose 31B, the liquid pipe 27, the liquid hose 31A, and the liquefied gas introduction pipe 32A
To the alternative container 2 through the Then, the operation of the gas compressor 22 is stopped when the container 1 to be inspected becomes empty, whereby the transfer operation of the liquefied gas from the container 1 to be inspected to the alternative container 2 is completed.

Thus, the gas compressor 2 replaces the container 1 to be inspected in place of the container 1 to be inspected.
By transferring the liquefied gas G remaining in the container 1 to be inspected by using the tank 2, a tank truck or the like for filling the liquefied gas G into the empty alternative container 2 can be prepared without any additional arrangement.
The operation of transferring the liquefied gas from the inspected container 1 to the substitute container 2 can be performed in a short time, and the continuous supply state of the liquefied gas G in the consumption facility A can be maintained.

Thereafter, as shown in FIG. 2, the gas hoses 29A, 29B and the liquid hoses 31A, 31B are stored in the hose storage 19 in an extended state. The alternative container 2 to which the liquefied gas G has been transferred is transferred to the consumption facility A using the crane 32, and the container 1 to be inspected removed from the consumption facility A is transferred to the loading platform 14 using the crane 32. The container 1 to be inspected is transported to the inspection station B separated from the consumption facility A.

In this case, the gas hoses 29A, 29B,
Since the base ends of the liquid hoses 31A and 31B are always connected to the gas compressor 22 fixed on the carrier 14, the distal ends of the gas hoses 29A and 29B and the liquid hoses 31A and 31B are used as substitute containers. By simply removing the hose from the container 2 and the container 1 to be inspected, the hose can be quickly removed.

Since the container 1 to be inspected is transported to the inspection station B by the exchange vehicle 11 in an empty state, for example, a float type liquid level gauge (not shown) is provided in the container 1 to be inspected. Even in this case, it is possible to reliably prevent the liquid level gauge from being damaged by the fluctuation of the liquid level at the time of conveyance.

The inspection container 1 transported to the inspection station B by the replacement vehicle 11 is subjected to, for example, an appearance inspection, an internal inspection, a pressure resistance inspection, an airtightness inspection in the inspection process shown in FIG.
We undergo various inspections such as valve inspection.

Next, the container 1 to be inspected transferred to the inspection station B
Is completed, the inspected empty container 1 ', which has been inspected, is transferred onto the carrier 14 of the exchange vehicle 11 using the crane 32 in the inspected container transporting step shown in FIG. 1 ′ is transported by the exchange vehicle 11 to the vicinity of the alternative container 2 installed in the consumption facility A.

Then, in the second liquefied gas transfer step shown in FIGS. 10 and 6, the liquefied gas remaining in the alternative container 2 is transferred into the inspected container 1 'using the gas compressor 22 as described below.

Also in this case, as in the first liquefied gas transfer step described above, the operation of transferring the gas compressor 22 between the loading platform 14 and the consuming facility A can be omitted. In addition, since the base ends of the gas hoses 29A and 29B and the liquid hoses 31A and 31B are always connected to the gas compressor 22, these gas hoses 29A and 29B are connected.
B. It is possible to quickly connect the gas compressor 22 with the inspected container 1 'and the alternative container 2 simply by connecting the distal ends of the liquid hoses 31A and 31B to the inspected container 1' and the alternative container 2. it can.

Thereafter, the liquefied gas G in the alternative container 2 is transferred into the inspected container 1 'by operating the gas compressor 22 to increase the pressure in the alternative container 2, and the empty state of the alternative container 2 is maintained. Gas compressor 22
Is stopped, the operation of transferring the liquefied gas from the alternative container 2 to the inspected container 1 'is completed.

Thus, also in the second liquefied gas transfer step, the liquefied liquid remaining in the alternative container 2 is replaced with the inspected container 1 ′ installed in the consuming facility A by using the gas compressor 22 instead of the alternative container 2. By transferring gas G,
The transfer operation of the liquefied gas from the alternative container 2 to the inspected container 1 'can be performed in a short time without separately arranging a tank truck or the like for filling the empty inspected container 1' with the liquefied gas G. Liquefied gas G at the consumption facility A
Supply can be maintained.

Then, as shown in FIG. 2, after the gas hoses 29A and 29B and the liquid hoses 31A and 31B are stored in the hose storage 19 in an extended state, in the alternative container take-out step shown in FIG. The inspected container 1 ′ to which the liquefied gas G has been transferred is transferred to the consumption facility A using the crane 32, and the alternative container 2 removed from the consumption facility A is transferred to the loading platform 14 using the crane 32, Take the alternative container 2 back to the laboratory B.

In this case, the gas hoses 29A, 29B,
Since the base ends of the liquid hoses 31A and 31B are always connected to the gas compressor 22 fixed on the carrier 14, the distal ends of the gas hoses 29A and 29B and the liquid hoses 31A and 31B have been inspected. By simply removing the hose from the container 1 'and the alternative container 2, the hose can be quickly withdrawn.

As described above, according to the exchange vehicle 11 of the present embodiment, the gas compressor 22 remains on the inspection container 1 (alternate container 2) using the gas compressor 22 while the gas compressor 22 is mounted on the carrier 14. The liquefied gas can be transferred into the alternative container 2 (the inspected container 1 '). For this reason, at the time of the transfer operation of the liquefied gas, the operation of transferring the gas compressor 22 between the loading bed 14 and the consumption facility A can be made unnecessary, and the inspection target container 1 ( The workability when replacing the alternative container 2) with the alternative container 2 (the inspected container 1 ') can be improved.

The liquefied gas transfer operation is performed while the gas compressor 22 is mounted on the carrier 14,
Gas hoses 29A and 29B, liquid hoses 31A and 3
The base end of 1B can always be connected to the gas compressor 22. Therefore, each gas hose 29A,
29B, by simply attaching and detaching the distal ends of the liquid hoses 31A, 31B to and from the container 1 to be inspected (alternate container 2) and the alternative container 2 (inspected container 1 '), the hose can be quickly attached and detached. Therefore, the workability when replacing the container to be inspected 1 (alternate container 2) installed in the consumption facility A with the alternative container 2 (inspected container 1 ') can be further improved.
