Description

[Detailed Description of the Invention] The present invention relates to a special vehicle transport vehicle, and more particularly to a transport vehicle for heavy special vehicles such as bulldozers equipped with caterpillars.

In general, vehicles with caterpillars such as bulldozers used for civil engineering work are slow, and when driven on roads covered with asphalt, the caterpillars damage the road surface, so they are moved using large transport vehicles. ing.

Transferring a special vehicle such as a bulldozer to a large transport vehicle can be carried out by suspending it using a large crane if available, but generally not every construction site has such a large crane, and However, it is not possible to move large cranes to the site one by one.

Therefore, a method was adopted in which a large, strong footboard was passed between the rear end of the truck's loading platform and the ground, and the bulldozer was guided onto the loading platform using the slope, but the footboard broke. There is a great danger that it may fall off or fall off.

In order to eliminate these drawbacks, improvements to the transport vehicle itself have been proposed.

FIGS. 1 and 2 illustrate this type of transport vehicle that is currently widely used. and 5 are correspondingly provided.

A rotating plate 7 is rotatably attached to the rear end of the loading platform 3 and can be tilted about a shaft 6 by a hydraulic cylinder (not shown).

Further, telescopic legs 8 are provided between the driver's seat 2 and the cargo platform 3.

The telescoping legs 8 are driven by a hydraulic cylinder 8a, and are retracted toward the cylinder 8a as shown in FIG. 1 when not in use.

When you want to load the bulldozer 9 on the structure described above, operate the cylinder 8a as shown in FIG.
Incline the whole so that the rear end is lower, then rotate the rotating plate 1 until the rear end touches the ground,
The bulldozer 9 is placed in a state where it is easy to place the bulldozer 9 on it.

In this state, the bulldozer 9 is operated and placed on the loading platform 3 from the rotating plate 7.

However, when the above structure is adopted, the height h of the high end of the rotating plate 7 from the ground must be strong enough to support a heavy bulldozer, etc., so the height is usually 20 cm or more. Even if you try to drive the bulldozer 9 over, it will get stuck and you will not be able to get on top of it.

Therefore, between the rear end of the rotating plate 7 and the ground,
A method was adopted in which the vehicle was tilted and a footboard (not shown) was handed over to the vehicle to enter the vehicle.

Therefore, there is a drawback that it takes time to attach and remove the footboards, making the work troublesome.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and provides a special vehicle transport vehicle configured to be able to ride on a bulldozer or the like without using footboards or the like.

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

FIGS. 3 and 4 illustrate an embodiment of the present invention, in which the same parts as in FIGS. 1 and 2 are designated by the same reference numerals.

In this embodiment, the rear end of the loading platform 3 is a frame 10 that is tilted downward and is fixedly provided.

As is clear from FIG. 4, this frame body 10 is approximately U-shaped when viewed from above, and has a stepped portion 11 at its rear edge.
is formed over the entire width except for a notch 13 for attaching the number plate 12.

The height of the stepped portion 11 is appropriately such that if the height of the edge of the frame body 10 is h, the height of the stepped portion 11 is approximately equal.
It is desirable that the amount of rearward protrusion of 1 is also approximately the same.

Incidentally, the rotating plate 1 is rotatably supported on the base of the frame 10 via a shaft 6, and is tilted by a hydraulic cylinder (not shown), but its size is similar to that of the frame 1.
The reinforcing frame 14 is provided on the lower surface of the reinforcing frame 14, and the non-slip member 15 is provided on the upper surface of the reinforcing frame 14.

Incidentally, in this embodiment, the number of steps 11 is illustrated as being only one, but it goes without saying that two or more steps may be provided; in this case, the height of the step portion is equal to the height of the frame 10 It is appropriate that the height is equal parts of the height of the edge.

Furthermore, it goes without saying that the anti-slip 15 may also be provided not only on the rotating plate 7 but also on the loading platform 3.

Since this embodiment is configured as described above, when in use, the entire loading platform 3 is tilted, and the rotating plate 1 is rotated with the lower rear end of the frame 10 touching the ground. and frame 1
Close the upper edge of 0.

If a bulldozer or the like is driven in this state, the rear edge of the frame 10 is formed with a step 11, so it is formed one step lower than when there is no step 11, and the end of the caterpillar can completely ride on the bulldozer and guide the bulldozer onto the rotating plate 7.

Since a non-slip surface 15 is formed on the rotating plate 1, the caterpillar does not slip and spin, and the bulldozer body can easily ride onto the loading platform 3.

When the bulldozer has completely climbed onto the platform 3, the platform 3 is returned to its original state by retracting the telescopic legs, the rotating plate 1 is also returned to the horizontal position, and the bulldozer is transported to the desired position.
What is necessary is to tilt the loading platform again toward the target position, tilt the rotary plate 1, and lower the bulldozer or the like.

As is clear from the above description, according to the present invention, an inclined frame is provided at the rear edge of the loading platform, a stepped portion is provided over the entire width of the edge of the frame, and the upper edge of the frame is closed. Because it is equipped with a rotating plate, it is possible to get on and off special vehicles such as bulldozers without the need for step boards, unlike conventional methods, and the transfer work of special vehicles is greatly simplified. Can be shortened.
