[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the contents described in the following embodiments. Furthermore, the components in the embodiments described below include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the embodiments described below may be combined as appropriate, or may be selected and used as appropriate.

[0015] As shown in the plan view of FIG. 1(A) and the front view of FIG. 1(B) when in use, and in the front view of FIG. 2 when stored, the embodiment of the bridging device 40 according to the present invention comprises a receiving platform 42 disposed on the gate 32 of the loading platform 30 of the road-rail vehicle, a pair of clamps 44 for fixing the receiving platform 42 to the gate 32, a fixed scaffold 46 that slides from the inside of the gate 32 upward (to the left in FIG. 1), and a clamp 44 for clamping the receiving platform 42 to the gate 32. and a tip support 50 rotatably arranged at the tip of the sliding scaffolding 48 by a hinge 49. When the gate board 32 is rotated counterclockwise in FIG. 2 around the axis 31 and tilted outward, and the tip support 50 is opened by the hinge 49, the gate board 32, the fixed scaffolding 46, the sliding scaffolding 48 and the tip support 50 form a bridge plank between the loading platform 30 and the platform 10.

[0016] In the figure, 52 is a lock pin for fixing the fixed scaffolding 46 in a retracted storage state by sliding it relative to the receiving base 42 and in an extended use state, and 54 is a lock pin for fixing the sliding scaffolding 48 in a retracted storage state by sliding it relative to the fixed scaffolding 46 and in an extended use state.

[0017] 3, the receiving stand 42 is composed of a pair of side plates 42A each having an L-shaped guide groove 43 formed therein, and a connecting plate 42B that connects the side plates 42A. In the figure, 42C denotes a coated wire that connects the lock pin 52 to the side plate 42A to prevent it from being lost. Like the lock pin 52, the lock pin 54 can also be connected to the side plate 42A or the like by a coated wire, for example, to prevent it from being lost.

[0018] As shown in detail in FIG. 4, the clamp 44 is composed of a generally C-shaped main body 44A, an adjuster 44B that is pressed against the gate plate 32, a knob 44C for moving the adjuster 44B, and a spring pin 44D for urging the adjuster 44B in a direction away from the gate plate 32 (upward in the figure).

[0019] The fixed scaffolding 46 is adapted to slide along a guide groove 43 formed in the receiving stand 42. This guide groove 43 is L-shaped and includes a groove 43A parallel to the gate plate 32 and a groove 43B directed outward from the gate plate 32 (downward in FIG. 1(B) and leftward in FIG. 2). Note that the shape of the guide groove 43 is not limited to an L-shape, and the intersection angle between the groove 43A and the groove 43B may be other than 90°, for example, a V-shape.

[0020] The surfaces of the fixed scaffolding 46 and the sliding scaffolding 48 are treated with anti-slip materials such as non-slip braces, and the tip support 50 is made of, for example, a checkered plate.

[0021] 5 shows an example of the shape of the hinge pin 49A for fixing the hinge 49 to the sliding platform 48 or the tip receiver 50. Note that the shape of the hinge pin 49A is not limited to this.

[0022] The tip support 50 is designed to form a slope when opened, allowing smooth movement from the bridging device 40 to the surface of the platform 10.

[0023] The state in which this embodiment is attached to the loading platform 30 of the road-rail vehicle 20 and used as a gangway is shown in Fig. 6(A) as a plan view and Fig. 6(B) as a front view.

[0024] 7(A) is a front view and (B) is a side view showing the state in which this embodiment is stored inside the tailgate 32 of the road-rail vehicle 20. In FIG. 7, 22 is a driver's seat of the road-rail vehicle 20, and 24 is a tire.

[0025] The installation procedure for using the bridging device 40 is shown in FIG.

[0026] In step S1000, from the stored state shown in Figure 9(A), the lock pin 52 of the fixed scaffolding 46 is removed, and as shown in Figure 9(B), the fixed scaffolding 46 is pulled upward and the lock pin 52 is fixed in the position for use where it is pulled upward from the gate board 32.

[0027] Next, proceed to step S1100, remove the lock pin 54 of the sliding scaffold 48, extend the sliding scaffold 48 upward, and lock the lock pin 54 in the position for use when the sliding scaffold 48 is pulled upward from the fixed scaffold 46, as shown in Figure 9 (C).

[0028] Next, the process proceeds to step S1200, where the tailgate 32 is rotated around the axis 31 relative to the loading platform 30 of the road-rail vehicle 20 and tilted outward (to the left in FIG. 9(D)).

[0029] Next, the process proceeds to step S1300, where, as shown in FIG. 9(D), the tip receiver 50 is opened by the hinge 49 and placed on the platform 10, thereby setting it into a usable state.

[0030] In the above embodiment, the present invention is applied to a road-rail vehicle consisting of a dump truck, but the application of the present invention is not limited to this, and it is clear that the present invention can be applied to road-rail vehicles other than dump trucks. Furthermore, it can be used not only between road-rail vehicles and platforms, but also as a bridge between truck beds. [Explanation of symbols]
