In Non-Patent Document 1 described above, the inside of the container vehicle is inspected by X-ray vertical irradiation and horizontal irradiation in an X-ray inspection tunnel for irradiating X-rays. However, since the X-rays irradiated by a part of the transfer device (the first transfer device and the second transfer device) that lift and transfer the front wheels of the vehicle are blocked, there is a problem that the X-ray inspection of the entire container vehicle cannot be performed. It was.
Moreover, this X-ray inspection apparatus needs to inspect not only large vehicles such as container vehicles, but also small vehicles such as passenger cars and small trucks. However, particularly in the case of a small vehicle, there is a problem that the range in which X-rays are shielded by the transfer device is wide, and the reliability of the X-ray inspection is lowered.

Similarly, in both cases of Patent Documents 1 and 2, the transport device is equipped with devices such as a driving device for driving (motor and speed reducer), a mechanism for operating the transport lifting device, and a hydraulic cylinder.
Therefore, for a large vehicle such as a container vehicle, the transfer device can be arranged so as not to be shaded by X-rays. However, in small vehicles and medium-sized vehicles, a part of the transfer device is placed on the vehicle body to be inspected by horizontal irradiation of X-rays. Since they are projected in an overlapping manner, the range that becomes the shadow of X-rays cannot be inspected.
Moreover, in the transport device that travels underground, the range in which the structural portion of the transport device overlaps the vehicle to be inspected is wide, and the range that cannot be inspected is large.

Further, the vehicle is stopped at a predetermined position with respect to the vehicle 1 to be tested, and the horizontal fork 16b is turned to be positioned at a support position (front and rear of the front wheel 1a of the vehicle 1 to be tested). By raising 16c, the front wheel 1a of the vehicle 1 can be lifted.

FIG. 5 is a first embodiment diagram of the movable carriage 14 and is a partially enlarged view of FIG.
In this example, each traveling rail 12 includes a main rail 12a and a pair of auxiliary rails 12b and 12c which are parallel to each other. The auxiliary rail 12b is located at the outer lower portion of the main rail 12a, and the auxiliary rail 12c is located opposite to the upper portion of the auxiliary rail 12b. In addition, a U-shaped reaction force wall 13a is provided outside the carriage passage 13 to support the auxiliary rail 12b.
In FIG. 5, the movable carriage 14 has a main wheel 15a and an auxiliary wheel 15b. The main wheel 15a and the auxiliary wheel 15b are coaxial in this example, but may be on different axes. Moreover, it is preferable to provide a plurality of main wheels 15a and auxiliary wheels 15b according to the load to be supported.

The main wheel 15a and the auxiliary wheel 15b guide the movable carriage 14 along the main rail 12a and the auxiliary rail 12b while supporting a downward load during normal traveling when the front wheel 1a of the test vehicle 1 is not supported.
On the other hand, when the front wheel 1a of the test vehicle 1 is supported by the horizontal fork 16b, a counterclockwise moment M acts on the movable carriage 14 in the drawing. This moment M is supported by the supporting force of the auxiliary wheel 15b by the auxiliary rail 12c. Therefore, when traveling with the front wheel 1a of the test vehicle 1 lifted, the main wheel 15a supports the downward load and moves along the main rail 12a and the auxiliary rail 12c with the main wheel 15a and the auxiliary wheel 15b. A cart 14 is guided.

  That is, the moving carriage 14 of the first embodiment shown in FIG. 5 is provided with the reaction wall 13a on the base side of the moment M caused by the vehicle weight generated in the left and right moving carriages 14 so that the auxiliary wheel 15b receives the reaction force.

With the above-described configuration, the pair of traveling drive motors 19 are driven in synchronization, whereby the pair of movable carriages 14 can be moved along the traveling rail 12 in synchronization.

FIG. 6 is an operation explanatory view of the above-described transport apparatus 10 of the present invention.
In this figure, 2 is a horizontal X-ray generator, 3 is a collimator, 4 is a horizontal X-ray detector, 5 is a vertical X-ray generator, 6 is a collimator, and 7 is a vertical X-ray detector.

In the present invention, in order to avoid the drawbacks of the above-described conventional transfer devices 8 and 9, the traveling surface 11 of the vehicle 1 to be tested is disposed above the moving carriage 14 of the transfer device 10 and the front wheel lift device 16 is checked. The vehicle 1 is disposed outside both side surfaces.
Therefore, with this configuration, the movable carriage 14 and the front wheel lift device 16 are not hidden behind the vehicle 1 to be tested in the horizontal inspection. Further, since the front wheel lift device 16 is on the ground with respect to the vertical direction and is located outside both side surfaces of the vehicle 1 to be examined, there is no structure that blocks vertical X-rays. Thereby, in the vertical irradiation and the horizontal irradiation of X-rays, only the horizontal fork 16b of the front wheel lift device 16 is shaded, and almost 100% of the vehicle 1 to be inspected can be inspected.

FIGS. 7A and 7B are views of a second embodiment of the transport device according to the present invention, where FIG. 7A is a side view and FIG. 7B is a front view.

The portal frame 21 is configured to receive a tipping moment M (see FIG. 5) that acts on a pair of movable carriages 14 that are divided into left and right. Therefore, the pair of movable carriages 14 can be moved along the traveling rail 12 in synchronization with the portal frame 21.
Other configurations are the same as those of the first embodiment.

  Also with the configuration of FIG. 7 (second embodiment), as shown in FIG. 6, the moving carriage 14 and the front wheel lift device 16 are not behind the vehicle 1 to be tested in the horizontal inspection. Further, since the front wheel lift device 16 is on the ground with respect to the vertical direction and is located outside both side surfaces of the vehicle 1 to be examined, there is no structure that blocks vertical X-rays. Thereby, in the vertical irradiation and the horizontal irradiation of X-rays, only the horizontal fork 16b of the front wheel lift device 16 is shaded, and almost 100% of the vehicle 1 to be inspected can be inspected.

In the case of the configuration shown in FIG. 7, one of the auxiliary rails 12b and 12c and the auxiliary wheels 15b and the pair of travel drive motors 19 of the movable carriage 14 shown in FIG. 5 can be omitted.
However, when the portal frame 21 of FIG. 7 is applied to an existing building, it cannot be adopted if there is no room in the building space.

  FIGS. 8A and 8B are views of a third embodiment of the transfer device according to the present invention, in which FIG. 8A is a side view and FIG. 8B is a front view. FIG. 9 is a second embodiment of the front wheel lift device 16, and is a partial plan view of FIG.

With the above-described configuration of the front wheel lift device 16, the front opening fork 22 a is retracted to the retracted position above the carriage passage 13, so that the transport device 10 can be moved back and forth along the rail 12 without interfering with the test vehicle 1. Can be moved to.
Further, the parallel link mechanism 22b is turned at a predetermined position with respect to the vehicle 1 to be tested, and the front-opening fork 22a is positioned at the support position (before and after the front wheel 1a of the vehicle 1 to be tested). By raising the open fork 22a, the front wheel 1a of the test vehicle 1 can be lifted.

That is, in the front wheel lift device 16 described above, the front-opening fork 22a that lifts the front wheel 1a of the vehicle 1 to be tested has a shape with a front-opening that opens and gradually narrows, and matches the front wheel 1a of the vehicle 1 to be tested. Thus, the front opening fork 22a can be moved to the front wheel 1a without moving the vehicle 1 to be tested by moving the carriage 14 back and forth by moving in parallel by the parallel link mechanism 22b so as to be inserted in parallel from the side. The front wheel 1a is scooped up by controlling the movement of the carriage and fork turning in combination so as to proceed to the center position of the vehicle.
When the front opening fork 22a enters the front wheel 1a, the lift cylinder 23 for lifting the front opening fork 22a is operated to lift the tip of the front opening fork 22a. Run.
When the test vehicle 1 is a large vehicle, the front-opening fork 22a is lifted at an outer position suitable for the large vehicle, and when the test vehicle 1 is a small vehicle, the front-opening fork 22a is small. Lift in an inward position suitable for the vehicle.
Further, when the front wheel 1a of the test vehicle 1 is lowered to the traveling surface 11 and the transport device 10 moves backward and returns to the original position, the test vehicle is turned by turning the front-opening fork 22a outward from the test vehicle 1. 1 can be avoided.

Further, as shown in FIG. 8B, in this example, as in the first embodiment (see FIG. 5), the main rail 12a, the auxiliary rails 12b and 12c, the reaction force wall 13a, the main wheel 15a, and the auxiliary wheel 15b, and when the front wheel 1a of the test vehicle 1 is supported by the front-opening fork 22a, the moment M acting on the movable carriage 14 is supported by the auxiliary wheel 15b and the auxiliary rails 12b and 12c. Yes.
Other configurations are the same as those of the first embodiment.

  In the third embodiment shown in FIGS. 8 and 9, the front wheel 1a is scooped up by a link mechanism (parallel link mechanism 22b and lift cylinder 23) that scoops up the front wheel 1a of the vehicle 1 to be tested by the front opening type fork 22a. It is the conveying apparatus 10 comprised so that it could move with the mobile trolley 14 located.

FIGS. 10A and 10B are diagrams of a fourth embodiment of the transfer device according to the present invention, where FIG. 10A is a side view and FIG. 10B is a front view. FIG. 11 is a plan view of FIG.
In this example, similarly to the third embodiment, the front wheel lifting device 16 shown in FIG. 8A is provided. Moreover, the portal frame 21 is provided similarly to 2nd Embodiment. In this example, a vehicle weight moment M acting on the front-opening fork 22a is received by connecting the left and right sides with the portal frame 21.
In this configuration, the mobile carriage 14 receives a moment M in the front-rear direction that acts on the front-opening fork 22a from the vehicle 1 to be tested, but is lifted by giving the mobile carriage 14 a weight equivalent to the reaction force of the vehicle. You can avoid it.
Other configurations are the same as those of the first embodiment.

  8 to 10 (third and fourth embodiments), as shown in FIG. 6, the movable carriage 14 and the front wheel lift device 16 are not hidden from the vehicle 1 to be tested in the horizontal inspection. Further, since the front wheel lift device 16 is on the ground with respect to the vertical direction and is located outside both side surfaces of the vehicle 1 to be examined, there is no structure that blocks vertical X-rays. Thereby, in the vertical irradiation and the horizontal irradiation of X-rays, only the horizontal fork 16b of the front wheel lift device 16 is shaded, and almost 100% of the vehicle 1 to be inspected can be inspected.

Moreover, in 1st-4th embodiment mentioned above, the movement of the mobile trolley | bogie 14 is comprised by the pulling by a wire, ie, a wire pulling type, and the movement of the mobile trolley | bogie 14 may be synchronized by the synchronizer 20. FIG.
