When the lift 30 is horizontal and the heights of the traveling rails 31 and 32 of the lift 30 are equal to the heights of the traveling rails 18 to 23 in the inspection room 12, the carriage 24a is moved from the inspection room 12 to the lift 30 by operating the control room 5. It can be moved to a position. Since the inspection chamber 12 is provided with the rails 15 and 16 and the X-ray shielding door 26, there is a gap between the traveling rails 18 to 23, but the gap and the size of the wheel 33 of the carriage 24a are different from each other. It goes without saying that the relationship is designed so as not to affect the movement of the carriage 24a. The lift 30 is formed integrally with the outer door, and when the lift 30 is closed, the examination room 12 is shut off from the outside. Lift 3
Controls such as opening / closing of 0 and adjustment of height are controlled by various control devices in the control room 5.

Next, the operation of the embodiment will be described.

The X-ray inspection vehicle is approached so that its rear side is on the platform 34 side, and is stopped when the distance between the vehicle and the platform 34 becomes approximately the length L of the lift 30. When the X-ray inspection vehicle is stopped, the lift 30 is opened by operating the control room 5 (the position shown by the solid line in the figure).
Together with the traveling rails 31 and 32 of the lift 30 and the inspection room 1
The height of the lift 30 is adjusted so that the heights of the two traveling rails 18 to 23 are equal. When the adjustment of the height of the lift 30 is completed, the carriage 24a is caused to travel on the travel rails 18 to 32 by a drive device (not shown) and moved to the position of the lift 30. When the carriage 24a moves onto the lift 30, the operator adjusts the heights of the traveling rails 31 and 32 of the lift 30 by the operation in the control room 5 so as to be equal to the height of the platform 34. When the adjustment of the height of the lift 30 is completed, the carriage 24b (the carriage having moved to the lift 30 is designated by reference numeral 24b) is moved onto the platform 34, and the carriage 24c (the carriage having been moved onto the platform 34 is designated as 24c). The object to be inspected 6a is mounted thereon by an operator or a forklift not shown. When the inspection object 6a is mounted on the carriage 24c, the worker
4c is moved from the platform 34 onto the traveling rails 31, 32 of the lift 30. The operator operates the control device 8 to adjust the heights of the traveling rails 31 and 32 of the lift 30 so as to be equal to the heights of the traveling rails 18 to 23 of the inspection room 12, and the carriage 24b inside the inspection room 12. It is moved by a driving device. The operator (or worker) is the X-ray shielding door 2
After closing 6, the X-ray source 13 irradiates the inspection object 6b with X-rays, and the X-ray source 13 is moved along the rails 15 and 16 so that the monitor 7b in the control room and the rear monitor 29 in the inspection room. The X-ray transmission image of the inspection object 6b is monitored. It should be noted that the inspection object 6b may be rotated by rotating the turntable 25 as needed, and the inspection object 6b may be subjected to an X-ray transmission inspection from another direction.

When the X-ray transmission inspection is completed, the operation of the X-ray source 13 is stopped, the X-ray shielding door 26 is opened, and the carriage 24a is moved to above the lift 30. When the carriage 24a stops on the lift 30, the traveling rail 3 of the lift 30 is moved as described above.
Adjust the height of 1, 32 to be equal to the height of platform 34. When the height adjustment of the lift 30 is completed, the carriage 24b is moved to the platform 34 and the inspection is completed.

In the above, according to this embodiment, the examination room 1
The running rails 18 not only on the floor in 2 but also on the lift 30.
32 are provided, the carriage 24a can be freely moved between the examination room 12 and the platform 34 by adjusting the height of the lift 30 even if there is a step between the X-ray examination vehicle and the platform 34. You can It is possible to easily mount the inspection object 6a on the carriage 24c that has moved onto the platform 34 and place it on the traveling rails 31 and 32 on the lift 30 by hand. The carriage 24b mounted on the lift 30 is guided into the traveling rails 18 to 32 and carried into the examination room 12. After the X-ray transmission inspection, the carriage 24a is easily carried out of the inspection room 12 through the lift 30 and onto the platform 34 by being guided by the traveling rails 18 to 32. Therefore, even if the object to be inspected 6a (6b) is a heavy object, the work of carrying in and out of the inspection room 12 and the platform 34 becomes easy.

The object to be inspected 6a (6b) is dolly 24a.
When mounted on (24b), the carriage 24a does not necessarily have to be moved onto the platform,
It goes without saying that it may be stopped and placed on the lift 30. Since the lift 30 can be lowered while the carriage 24b is placed on the lift 30, the inspection object 6a (6b) can be mounted at the ground level.

When the turntable 25 can rotate the inspection object 6b in the inspection chamber 12, the inspection object 6b can be inspected not only from one direction but also from a desired angle.

In this embodiment, the X-ray source 13 and the detector 14
Are formed so as to move in the left-right direction of the vehicle, but the present invention is not limited to this, and they may be formed so as to move in the front-back direction of the vehicle.

The X-ray tube voltage of the X-ray source 13 described above can be varied from 75 KV to 300 KV. In the conventional X-ray inspection vehicle of this type, the X-ray tube voltage is 14 KV.
Nothing that can be set to 0 KV or higher has been realized, and since the X-ray tube voltage of the X-ray source 13 can be set to 140 KV or higher as in the present embodiment, it is not limited to large cargo and the conventional X-ray tube can be used.
It is possible to obtain a transmission image of an object having a large specific gravity that could not be inspected by the line inspection vehicle. For reference, a comparative example when the X-ray tube voltage is 140 KV and when it is 300 KV is shown.

[Comparative Example] X-ray tube voltage (KV) Inspection object Penetration capacity (mm) 140 Iron 15 140 Water (ice) 200 300 Iron 65 300 Water (ice) 400 Image display of the above-mentioned X-ray inspection vehicle Since only the X-ray transmission image (silhouette) in one direction is displayed on the apparatus, the shape of the article inside may not be recognized depending on the arrangement state of the inspection object.

For example, the silhouette 40a of the pistol 40 as a forbidden article seen from the direction of the arrow A is clearly a pistol as shown in FIG. Although it is easy to find it by the X-ray transmission inspection, the silhouette 40b when viewed from the direction of the arrow B looks like a rod as shown in FIG. 2C, and therefore when it is hidden inside the inspection object. In the X-ray transmission inspection, the inspector may mistakenly recognize it as a prohibited item and may overlook it. 2A is a perspective view when the handgun is hidden inside the inspection object.

Therefore, the present inventors have proposed an X-ray inspection apparatus in which an inspector surely finds a forbidden item hidden in an object to be inspected.

This is an X-ray inspection apparatus for irradiating an inspection object 6b in an inspection room 12 formed in a vehicle or the like with X-rays to obtain a transmission image, in which the inspection object 6b is placed in a horizontal plane. Turntable 25 as a rotating mechanism
And the X-ray source 13 and the detector 14 are arranged with the turntable 25 as a boundary so as to change the orientation of the inspection object 6b and obtain a plurality of X-ray transmission images viewed from different directions. is there.

A vehicle having such an X-ray inspection apparatus is
The rear side is approached so as to be on the side of the platform 34, and is stopped when the distance between the vehicle and the platform 34 becomes substantially the length L of the lift 30. When the X-ray inspection vehicle is stopped, the lift 30 is opened by operating in the control room 5, and the height of the lift 30 is adjusted so that the inspection object 6a can be carried in from the platform 34. When the adjustment of the height of the lift 30 is completed, the carriage 24c is caused to travel on the traveling rail and is made to stand by at the position (24a) on the lift 30.
After the object 6a to be inspected is placed on the trolley 24b waiting for the lift 30, the trolley 24b is moved to the inspection position (24
After moving to a), the X-ray shielding door 26 is closed.

3 (a) and 3 (b) are layout diagrams showing the positional relationship between the object to be inspected, the X-ray source and the detector in the inspection chamber, and FIG. 3 (c) is the same as FIG. 2 (a). 3D shows a transmission image of the inspection object, and FIG. 3D shows a transmission image of the inspection object in FIG. 2B. The case where the pistol is hidden in the object to be inspected will be described.

In FIGS. 3B and 3D, when the X-ray source 13 and the detector 14 move in the arrow direction from the position shown by the solid line to the position shown by the broken line, X from the X-ray source 13
Since the lines are emitted along the lateral direction of the pistol 40, the transmission image displayed on the X-ray transmission image monitor 7b is shown in FIG.
It becomes the silhouette 40b of the pistol 40 like this. At this stage, the inspector can easily and surely find the handgun 40 hidden inside the inspection object 6b.

Therefore, even if it is not possible to find that the pistol 40 is hidden in the inspection object 6b by merely observing the image when the X-ray passes through the inspection object 6b from one side, By observing the image when the X-rays pass through the inspection object 6b from the other side, the handgun 40 hidden inside the inspection object 6b can be found.

As described above, according to this embodiment, a turntable for rotating the inspection object on a horizontal plane is provided, and the direction of the inspection object is changed by the turntable to obtain a plurality of X-ray transmission images viewed from different directions. Therefore, even if it is not possible to distinguish from other things only from an image from one direction, you can easily distinguish from other directions, so you can easily distinguish the handgun hidden inside the inspected object. The X-ray transmission inspection can be performed efficiently and reliably in a short time. still,
In the present embodiment, the rotation angle of the turntable is set to about 90 degrees, but it is not limited to this. Further, although the case where the inspection object is carried in from the platform has been described in the present embodiment, the present invention is not limited to this, and after the inspection object 6a is placed on the lift 30 by a hawk lift not shown,
