Description

[Detailed Description of the Invention] (Field of Industrial Use) The present invention relates to a movable three-dimensional road end module end approach folding device applied to a temporary road at the time of road surface repair work on an elevated road or the like.

(Prior Art) An example of a conventional folding device of this type will be described with reference to FIGS. 12 and 13. A main girder (24) of the end approach has a hinge fitting on an end module (2) that comes into contact with the repair road surface. (15) and the link (23),
The floor plate (24) is folded over the fixing member (25) by the cylinder (11) connected to the link (23). Then, the folding link (23), the cylinder (11), and the fixing member (25) are installed in the main girder portion of the main body side structure, and the main body is folded with the widening operation of the ent approach floor plate (10). It has a structure that works with the widening operation on the side.

(Problems to be solved by the invention) Therefore, when the end module is installed at the road repair place, the folding link, the cylinder, and the fixing member are exposed at the main girders on the side of the end module. It is necessary to install a cover that protects these folding devices in order to minimize damage in case of contact or collision due to a passing vehicle. As a result, it is difficult to continuously install the gart rail from the end module side toward the central module direction, and there is a problem that the driver of the vehicle is given a narrow road width.

The present invention was developed to deal with such a problem, and its object is to install the folding device in the main girder.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 7 corresponding to the embodiments. A movable three-dimensional road consisting of E and F and an end approach that is foldably connected to the end modules E and F via a fold link (23) that is connected to a hinge fitting (15) and a cylinder (11). In the end module end approach folding device,
The cylinder (11) in the end module main girder (2)
And the folding link (23) and the stopper (16) for holding the end approach at the folding position are installed in the main girder (6) of the end approach.

(Operation) The present invention is that the cylinder and the folding link connected to the cylinder are incorporated into the main girder of the end module and the main girder of the end approach by the above means, and the stopper that holds the end approach in the folding position is also the end approach. Since it is incorporated in the main girder of the vehicle, the end module and the end approach have a small number of protrusions, and the narrow feeling to the driver of the vehicle can be reduced.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 7, where S is a work module and A, B, C, D, E, F, are modules, and a floor plate of each module. (1) and the main girder (2) are connected by a connecting device (3), and a traveling device (4) and a mobile traveling device (5) are provided on the lower surface of the main girder (2). . (6) shows a main girder of the end approach, and the main girder (6) is connected to the main girders (2) of the end modules E and F through a hinge fitting (15) having a center pin (20), A cylinder (11) installed in the main girder (2) of the end modules E, F, and a shaft (12) of the cylinder (11).
A link (13) connected to the link (13) via a pin (18) and a connecting fitting (1) connected to the link (13) via a pin (19).
A folding link (23) consisting of 4) is installed in the main girder (6) of the end approach, and the main girder (6) further includes a stopper (16) which holds the folded position when the girder is folded. ) Is pivotally supported by a pin (21), and the other end of the stopper (16) has a stop pin (22) on the main girder (2).
It was made to be supported by. The shaft (12) is guided by the cylinder shaft guide (17).

In the figure, (7) shows the telescopic support legs of each module, (8) shows the balustrade, (9) shows the widening device, and (10) shows the ent approach floor plate.

Thus, as shown in FIGS. 8 and 9, when the trailer is inserted, loading is completed, and the vehicle is running, the cylinder (11) is operated to move the cylinder shaft (12) to the cylinder shaft guide (17).
The end approach is rotated around the pin of the hinge fitting (15) by the link (13) and the connecting fitting (14) and folded toward the end module main body side. During transportation, the stopper (16) rotates by its own weight around the pin (21), descends downward, and is fixed to the end module main girder (2) with a pin (22). In addition, as shown in Fig. 10 and Fig. 11, when contacting with a road repair location, follow the procedure reverse to that for loading and transporting to the trailer.

(Effect of the Invention) As described above, according to the present invention, the folding cylinder is provided in the main girder of the end module, and the folding link connected to the folding cylinder and the ent approach are provided in the main girder of the end approach. Since the stopper for holding the folded position is provided, these folding members are installed in the main girders of the end modules and the main girders of the end approach without being exposed to the outside, and these members are not exposed. It has the effect of not contacting or colliding with a passing vehicle.
