In order to solve the above-described problems, the present invention has the configuration as described in each claim of the claims.
According to the first aspect of the present invention, the lowermost deck has a road plate that supports the right wheel of the vehicle mounted on the deck and a road plate that supports the left wheel of the vehicle separately. The front side of each road plate is vertically movably supported by the front elevating means, and the rear side of each road plate is vertically movably supported by the rear elevating means.
That is, the lowermost deck has left and right road boards provided separately. The front and rear sides of each road plate are supported so as to be vertically movable.
[0006]
Accordingly, the lowermost deck can be provided at desired positions by separately providing the left and right road boards. For example, by providing the road plate at a position avoiding the frame of the vehicle carrier, the road plate can be easily moved downward.
In addition, the front side and the rear side of the road plate are separately movably supported by the front-side elevating means and the rear-side elevating means. Therefore, the road plate can move up and down while being horizontal, and can move up and down only on the front side or only on the rear side.
Therefore, the lowermost deck can be easily moved up and down. Further, the inclination of the road plate can be appropriately changed depending on the shape of the vehicle to be mounted.
[0007]
According to the invention described in claim 2, the vehicle carrier has a guide support member that guides and supports a guide portion formed at the front end or the rear end of the road plate.

And an arm extending from the shaft to the right road plate and supporting the right road plate from below. The two arms are provided integrally with the shaft, and are configured to swing together with the shaft about the shaft.
[0009]
That is, the tuning structure has an arm that supports the left road plate from below and an arm that supports the right road plate from below. These arms simultaneously swing about the shaft as the rotation axis, and simultaneously move the left and right road plates up and down.
Therefore, the left and right road boards move up and down synchronously by the synchronizing structure, and the vehicle mounted on the left and right road boards moves up and down without leaning in the vehicle width direction. The vehicle thus mounted can move up and down stably without falling off from the vehicle carrier.
[0010]
According to the invention described in claim 4, the vehicle carrier has a plate width inclination preventing structure for preventing the road plate from being inclined in the plate width direction. The plate width inclination preventing structure includes a shaft extending in a plate width direction of the road plate below the road plate and rotatably supported in a direction around an axis with respect to a frame of the vehicle carrier. And an arm extending from the shaft to the right end of the road plate and supporting the right end from below. The two arms are provided integrally with the shaft, and are configured to swing together with the shaft about the shaft. Also, rails are provided along the edges at both left and right ends of the road plate to support the front end of each arm movably in the front-rear direction.

[0014]
The road plate 20 is provided immediately behind the driver's seat 10 as shown in FIG. 1, and is fixedly attached to the frame (13). The road plate 22 is provided above the rear wheel 12 and attached to the frame (13).
The road plate 21 is provided between the front wheel 11 and the rear wheel 12, and is supported to be vertically movable with respect to the frame (13).
That is, as shown in FIG. 2, between the road plate 21 and the frame 13, front-side elevating means 5a and 5b for vertically supporting the front side of the road plate 21 and vertically supporting the rear side of the road plate 21. Rear elevating means 5c and 5d are provided.
[0015]
As shown in FIG. 3, the lifting means 5 a to 5 d include a shaft 6 extending below the road plate 21 in the vehicle width direction, and arms 50 and 51 extending from the shaft 6 toward the lower surface of the road plate 21. And a hydraulic cylinder 55 (for example, a hydraulic cylinder) for swinging the arms 50 and 51.
As shown in FIG. 5, the shaft 6 is rotatably supported on the lower surface of the center frame 13a around the axis. As shown in FIG. 3, one ends of the arms 50 and 51 are integrally attached to the shaft 6. Therefore, the arms 50 and 51 swing about the shaft 6 together with the shaft 6.
[0016]
The arms 50 and 51 have guide rollers 52 and 53 at their distal ends as shown in FIG. An axle 54 is attached to the distal ends of the arms 50 and 51 so as to be rotatable around the axis so as to straddle between them, and guide rollers 52 and 53 are attached to the axle 54. The guide rollers 52 and 53 are configured to be movable in the front-rear direction below the road plate 21 by rotating about the axle 54.
At the center of the axle 54, a mounting portion 55a is mounted so as to be rotatable around the shaft, and the tip of the hydraulic cylinder 55 is mounted on the mounting portion 55a.
The other end of the hydraulic cylinder 55 is swingably attached to a support 13 b provided on the frame 13.
[0017]
Therefore, when the hydraulic cylinder 55 expands and contracts, the hydraulic cylinder 55 swings the arms 50 and 51 as shown in FIGS. At this time, the hydraulic cylinder 55 swings about the support portion 13b, and the arms 50 and 51 swing about the shaft 6. Then, the arms 50 and 51 move the road plate 21 up and down.
The arm 50 supports the right end of the road plate 21 as shown in FIG. 3, and the arm 51 supports the left end of the road plate 21. Thus, the left and right ends of the road plate 21 are supported by the arms 50 and 51.
[0018]
Also, rails 70 and 71 are provided at both left and right ends of the road plate 21 along the edges thereof.
The rails 70 and 71 are mounted on the lower floor of the road plate 21, and guide rollers 52 and 53 are mounted in the rails 70 and 71. The rails 70 and 71 support the guide rollers 52 and 53 so as to be movable in the front-rear direction, and regulate the movement of the guide rollers 52 and 53 in the plate width direction. Therefore, the arms 50 and 51 are prevented from coming off the road plate 21 by moving in the plate width direction, and stably support the left and right ends of the road plate 21.
[0019]
Further, guide portions 73 and 74 are attached to the leading end of the road plate 21 as shown in FIG. The guide portions 73 and 74 are attached to left and right ends of an axle 72 extending in the vehicle width direction of the road plate 21, and the axle 72 is attached to the rails 70 and 71 so as to be rotatable around the axis.
Therefore, the guide portions 73 and 74 are attached to the leading end of the road plate 21 via the axle 72 and the rails 70 and 71, and are located at the left and right ends of the road plate 21.
[0020]
As shown in FIG. 4, a guide support member 14 is provided between the road plate 21 and the road plate 20 to guide and support the guide portions 73 and 74 so as to be movable in the vertical direction. The guide support member 14 extends substantially vertically, and is attached to the frame (13) or the road plate 20.
The guide support member 14 supports the road plate 21 so as to be tiltable around the guide portions 73 and 74 as shown in FIGS. Further, the guide support member 14 regulates the movement of the road plate 21 in the front-rear direction.
On the other hand, the rear end of the road plate 21 has no guide portion as shown in FIGS. 3 and 4, and is not guided and supported by the guide support member. Therefore, the rear end of the road plate 21 is a free end, so that the vertical movement and the tilting of the road plate 21 are facilitated.
[0021]
Further, the vehicle carrier 1 has a tuning structure in which the left road plate 21a and the right road plate 21b are tuned up and down. This tuning structure includes the shaft 6 shown in FIG. 3, the arms 50a and 51a supporting the left road plate 21b, and the arms 50b and 51b supporting the right road plate 21a.
The shaft 6 extends in the vehicle width direction of the vehicle carrier 1 and extends across the left road plate 21a and the right road plate 21b.
[0022]
The arms 50a, 51a supporting the left road plate 21a and the arms 50b, 51b supporting the right road plate 21b are both attached at one end to the shaft 6, so that the shaft 6 It swings with the shaft 6 as the axis center.
Therefore, the arms 50a, 51a, 50b, and 51b oscillate synchronously via the shaft 6, and simultaneously move the right and left road plates 21a and 21b up and down.
Therefore, the left and right road boards 21a and 21b move up and down in synchronization with this tuning structure. Therefore, the vehicle mounted on the left and right road boards 21a and 21b is stably moved up and down without leaning in the vehicle width direction, and is prevented from falling off from the vehicle carrier 1.
[0023]
The vehicle carrier 1 also has a plate width inclination prevention structure for preventing the road plate 21 from being inclined in the plate width direction. This plate width inclination prevention structure includes the shaft 6 shown in FIG. 3, an arm 51 supporting the left end of the road plate 21, and an arm 50 supporting the right end of the road plate 21. Since both arms 50 and 51 are provided integrally with the shaft 6, the arms 50 and 51 swing together with the shaft 6 around the shaft 6.
Therefore, the arms 50 and 51 simultaneously swing about the shaft 6 as a rotation axis, and simultaneously move the left and right ends of the road plate up and down. Therefore, the left and right ends of the road plate 21 move up and down synchronously by the plate width inclination preventing structure, and are prevented from being inclined in the plate width direction. Therefore, the vehicle mounted on the road board 21 moves up and down stably without leaning in the board width direction.
[0024]
The guide rollers 52 and 53 provided at the distal ends of the arms 50 and 51 are supported by rails 70 and 71 provided at both left and right ends of the road plate 21 so as to be movable in the front-rear direction. For this reason, the distal ends of the arms 50 and 51 are prevented from being detached from the road plate 21 by the rails 70 and 71, and the left and right ends of the road plate 21 are stably supported by the arms 50 and 51.
[0025]
Next, the usage of the road plate 21 will be described.
As shown in FIG. 6, the road plate 21 is normally used at a position where the heights of the road plates 21 and 22 are the same. When the height of the vehicle mounted on the road plate 21 is high, the road plate 21 is lowered as shown in FIG.
For example, the front plate 5 and the rear plate 5c and 5d are simultaneously operated to lower the front and rear sides of the road plate 21 at the same time, thereby lowering the road plate 21 in a horizontal state. Alternatively, the road plate 21 is lowered by lowering one end side of the front side or the rear side of the road plate 21 first and lowering the other end side thereof (see FIGS. 7 and 8).
[0026]
Further, the road plate 21 can be in a state where only the rear side is lowered and inclined as shown in FIG. 7, and a state where only the front side is lowered and inclined as shown in FIG.
Therefore, the road plate 21 can be used in various modes, and the mode can be changed depending on the shape of the vehicle to be mounted.
The lifting means 5a to 5d operate by extending and retracting the hydraulic cylinder 55, and therefore easily operate.
[0027]
The upper deck 3 has a road plate 30 provided above the driver's seat 10 and a road plate 31 provided above the lowermost deck 2 in series as shown in FIG.
The road plate 31 has a structure in which the rear side can be lowered by the wire 32 and the vehicle can be mounted along the road plate 31 by lowering the rear side to make the vehicle slant.
[0028]

The left side of the road plate 21a is vertically movably supported by the front elevating means 5a, and the rear side is vertically movably supported by the rear elevating means 5c. The right side of the road plate 21b is supported by the front elevating means 5b so as to be vertically movable, and the rear side is supported by the rear elevating means 5d so as to be able to move vertically.
Accordingly, the lowermost deck 2 can be provided at desired positions by separately providing the left and right road boards 21a and 21b. For example, by providing the road plates 21a and 21b at positions avoiding the center frame 13a of the vehicle carrier 1 as shown in FIG. 2, the road plates 21a and 21b can be easily moved downward as shown in FIG.
[0029]
The road plate 21 is supported so that the front side and the rear side can be moved up and down separately by front-side elevating means 5a and 5b and rear-side elevating means 5c and 5d. Therefore, the road plate 21 can move up and down in the horizontal direction, and can move up and down only on the front side or only on the rear side.
Therefore, the lowermost deck 2 can be easily moved up and down. In addition, the inclination of the road plate 21 can be appropriately changed depending on the shape of the vehicle to be mounted.
[0030]
The leading end of the road plate 21 is guided and supported by the guide support member 14 as shown in FIGS. The road plate 21 is supported by the guide support member 14 so that the movement in the front-rear direction is restricted, thereby preventing the road plate 21 from coming off the frame 13 of the vehicle carrier 1.
One end of the road plate 21 is supported, and the road plate 21 is tilted about the guide portions 73 and 74. Therefore, the road plate 21 can be easily inclined.
