As shown in FIG. 7 , the limit switch 21 is installed on the housing 16 in such a manner that it contacts the corresponding baffle 19 when the baffle 19 reaches the upper limit position. The limit switch 21 outputs an ON/OFF signal representing contact/non-contact with the baffle 19 for monitoring the lifting status of the baffle 19 .

The limit switch 21 may be installed on the housing 16 in such a manner that it contacts the corresponding baffle 19 when the baffle 19 reaches the downward limit position. In addition, the limit switch 21 may not be installed on the housing 16 , but may be installed on a component of the link mechanism 20 , as long as the limit switch 21 can detect the lifting state of the baffle 19 .

The ramp 22 is made of a metal material such as iron, and is detachably mounted to the vehicle front side and the vehicle rear side of the housing 16 as shown in FIGS. 1 to 5 .

As shown in FIGS. 3 to 5 , each ramp 22 includes a body 60 and an insert 61 . The body 60 includes an inclined surface 60 a configured to guide the tire 4 to the roller 15 . The insert 61 includes an end that is inserted into a corresponding slot 37 of the housing 16 . The body 60 has a cross section shaped into a substantially right-angled triangle in which the inclined surface 60 a is the hypotenuse of the triangle, and serves as a continuous surface connecting the top surface of the housing 16 with the floor surface of the place where inspection is performed.

The insert 61 has a substantially L-shaped cross section and includes a flat portion 61 a protruding from the body 60 and an insert portion 61 b extending downward in the vehicle height direction (ie, in the downward direction in FIG. 5 ) from the flat portion 61 a. The insert 61 is formed by bending a rectangular plate into an L shape, for example.

As shown in FIG. 3 , each ramp 22 is formed by inserting the insertion portion 61 b of the insert 61 into the corresponding slot 37 of the housing 16 at a position displaced relative to the position in which the support 35 b of the support device 35 is inserted. Removably mounted to housing 16. The insert 61 is positioned closer to the vehicle in the vehicle width direction than the support 35 b of the support device 35 . The insertion portion 61 b of the insertion member 61 is inserted into the groove 37 at a position closer to the vehicle than the support member 35 b of the support device 35 .

Therefore, the ramp 22 and the side roller 17 are installed into the same groove at different positions.

Each pair of tire support devices 2 whose positions are different from each other in the front-rear direction of the vehicle 3 is different from each other with respect to the length of the slope 22 mounted to each pair of tire support devices 2 in the vehicle front-rear direction. In other words, the length of the slope 22 mounted on the pair of left and right tire support devices 2a for the front wheels of the vehicle 3 in which the tires 4 for the front wheels of the vehicle 3 idle is the same as the length in the vehicle front-rear direction of the left and right pairs of tires 4 mounted on the rear wheels of the vehicle 3. The slopes 22 on the pair of tire supports 2b are different.

As mentioned above, the inspection device 1 (ie, the tire support device 2) may be provided or mounted on a flat surface (ie, a floor surface) on which the vehicle 3 may travel.

Therefore, the inspection device 1 eliminates the need to prepare pits or recesses on the floor for accommodating various components (for example, the link mechanism 20 for raising and lowering the baffle 19) when installed, and helps to improve selection Flexibility in where inspections are conducted.

The inspection device 1 (tire support device 2 ) includes a baffle 19 configured to interface with the tire 4 . This allows the vehicle 3 to ride on and off the inspection device 1 by means of a self-propelled propulsion without the need for additional devices such as a winch.

The inspection device 1 (tire support device 2) is configured such that the baffle 19 is provided between the rollers 15 and fills the gap between the rollers 15. This helps prevent the roller 15 from pinching the operator's fingers. Therefore, the inspection device 1 (tire support device 2) contributes to increased operational safety since the baffles 19 are provided between the rollers 15.

The inspection device 1 (tire support device 2) includes a limit switch 21. This is useful for understanding whether the tire 4 of the vehicle 3 is allowed to ride on or off the roller 15 .

Each tire support device 2 includes three moving rollers 25 rotatably mounted to the housing 16 . This allows each tire support device 2 to be easily moved by the rotation of the moving roller 25 while maintaining the attitude of the housing 16 horizontally. In particular, when the tire supporting device 2 is moved by the rotation of the moving rollers 25, the three moving rollers 25 allow the tire supporting device 2 to move in a direction inclined relative to the rolling direction of the rollers 15 in a plan view (in other words, along a direction in the plan view). moving the tire support device 2 in the direction of rotation). This facilitates fine-tuning of the arrangement of the tire support device 2 .

Each pair of tire supporting devices 2 aligned in the vehicle width direction is coupled to each other via a coupling 24 which is an elongated rectangular plate.

This allows each pair of tire supports 2 aligned in the vehicle width direction to match the center position of the left and right pair of housings 16 , and allows the left and right pair of housings 16 to match the positions of the bulges and depressions caused by the rollers 15 match. This allows each pair of left and right tires 4 to spin under substantially the same conditions when idling on the roller 15 . Therefore, the inspection device 1 allows each pair of left and right tires 4 to idle under substantially the same conditions, thereby helping to improve the accuracy of inspection.

The inspection device 1 (tire support device 2) includes side rollers 17. This suppresses the vehicle 3 from moving in the vehicle width direction (ie, rushing out) during the inspection, thereby suppressing the vehicle 3 from falling from the inspection device 1 (tire support device 2).

The inspection device 1 (tire support device 2) is configured to allow the installation position of the side roller 17 to be changed according to the tread width of the vehicle 3, thereby adapting to vehicles with various tread widths.

Each tire support device 2 is removable in the state in which the ramp 22 has been removed. This facilitates mounting of the tire support device 2 according to the wheelbase length of the vehicle 3 .

The ramp 22 is detachably mounted to the tire support 2 . This facilitates moving and storing the tire support device 2 .

Each pair of tire support devices 2 whose positions are different from each other in the vehicle front-rear direction differs from each other with respect to the length of the slope 22 mounted to each pair of tire support devices 2 in the vehicle front-rear direction.

This results in a different contact time between the ramp 22 and the tires 4 of the front wheels of the vehicle 3 than between the ramp 22 and the tires 4 of the rear wheels of the vehicle 3 and reduces the force required for the vehicle 3 to ride onto the ramp 22 .

This allows the vehicle 3 to easily ride on the tire support device 2 through a self-propelled device or through an operator's manpower without requiring additional devices, and facilitates inspection using the inspection device 1 .

Each tire support device 2 includes a support 35 b of the support device 35 and an insert 61 of the ramp 22 , both of which are inserted in a groove 37 of the housing 16 .

Therefore, each tire support device 2 is configured so that the ramp 22 and the side roller 17 are mounted into the same groove. This helps to simplify the structure of the tire support device 2 for mounting the ramp 22 and the side roller 17, thereby increasing productivity while reducing costs.

Each tire support device 2 includes a safety barrier 18 removably mounted at an outer position relative to the side rollers 17 . This ensures safety and prevents the rotating tire from becoming entangled during inspection 4. Therefore, the inspection device 1 helps ensure safety during inspection.

Although specific embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, but may be variously modified without departing from the intent of the present invention.

For example, the inspection device 1 may be modified to provide tire support devices 2 for only part of the tires 4 of the vehicle 3 .

Furthermore, the number of rollers 15 in each housing 16 is not limited to four, but may be a plural number other than four.
