Description

[Detailed description of the invention] The present invention relates to a self-propelled floating bridge that can be moved to any location and erected an emergency bridge over a river, and in particular, it is a self-propelled floating bridge that can be moved to any location and used to construct a bridge over a river in an emergency manner. The present invention relates to the arrangement and structure of floating bodies suitable for quickly constructing bridges.

In conventional self-propelled floating bridges, the floating bodies 2 and 3 were installed side by side on the upper part of the vehicle body 1, as shown in Figure 1 as a side view of the vehicle when it is running on land, and Figure 2 as its cross-sectional view. As shown in Fig. 3, which is a cross-sectional view of the floating bodies 2 and 3 in the water bridge position, when the floating bodies 2 and 3 are deployed to the left and right of the car body 1 by the hinges 4, the total width is limited to about twice the car body width, and the floating bodies 2 and 3 are placed closely together. Since the number of vehicles (boats) would be significantly large in order to connect them to form a floating bridge, the vehicles are arranged at intervals and connected by bridge bodies 5, as shown in FIG. For this reason, the car body 1
After adding floating bodies 2 and 3 to increase buoyancy, a bridge body 5 is further loaded as shown in Figures 1 and 2,
In addition, a crane (not shown) is equipped to move the bridge body 5 from this loading position to the bridge position shown in Figure 3, which not only complicates the structure but also increases the weight of the vehicle and makes it difficult to maneuver. This has the disadvantage that the bridge construction time and the number of personnel required are increased because it requires operations and time to move the bridge body 5.

In addition, in FIGS. 1 and 2, since the bridge body 5 is loaded between the vehicle body 1 and the floating bodies 2 and 3 within the height limit of the vehicle, the height of the floating bodies 2 and 3 cannot be made very large.
In addition, in Fig. 3, the bridge body 5, the car body 1, the floating body 2,
In order to be able to transmit the bending moment between 3 and 3, it is necessary to connect them with pins 6 and rods 7, and it is difficult to make the top surface of the car body and the top surface of the floating body the same plane, so the top surface of the car body and the top surface of the bridge body 5 They form a passageway on the same plane.

Next, in other conventional self-propelled floating bridges, the bridge body 10 is attached to the upper part of the vehicle body 8 via a swing device 9, as shown in FIG.
The bridge body 10 is turned horizontally by 90 degrees with respect to the vehicle body 8 in the overwater bridge attitude as shown in the cross-sectional view in FIG. to form a floating bridge. This method had the disadvantage that the width of the vehicle when traveling on land was not smaller than the width of the bridge body, which caused a major hindrance to road traffic. In addition, in this system, a passageway is formed on the upper surface only by the bridge body 10, and the vehicle body 8 is used only as a buoyancy support, and the functions of the two are separated.

As mentioned above, none of the conventional bridges can make the vehicle width very large in the floating bridge position, so by using a separate bridge body, the distance between adjacent vehicles is increased and the number of vehicles required for the floating bridge is reduced. It is necessary to reduce the amount of water, which results in the above-mentioned drawbacks.

The purpose of this invention is to make it possible to form a floating bridge with a relatively small number of people by widening the width when unfolded, and
It is an object of the present invention to provide a self-propelled floating bridge whose structure can be simplified by using the floating body and the upper surface of the vehicle body as passage surfaces.

The present invention consists of a car body that runs on land and floats on water, and two floating bodies that have the same width as the car body and are mounted on the car body.One floating body is mounted on the top of the car body, and , on which the other floating body is mounted,
Each floating body is rotatably attached to the vehicle body at both sides in the vehicle width direction around a rotating shaft arranged in the longitudinal direction of the vehicle body, and the center of the rotating shaft is aligned between the passage surface of the vehicle body and the passage surface of each floating body. It is characterized by being placed in the central position.

An embodiment of the present invention will be described below with reference to FIGS. 7 to 11. Fig. 7 is a side view of the vehicle in the land running position, and Fig. 8 is a sectional view taken along line A-A in Fig. 7, with the vehicle body 1
A right floating body 13 (left and right may be reversed; the following is omitted) having a width approximately equal to the width of the vehicle body is installed on the upper part of the vehicle body 12, and this and the vehicle body 12 are rotatably connected via a hinge pin 14 and pins 15 and 16. has been done.
In addition, a cylinder 17, an arm 18, and a cylinder 19 are provided between the vehicle body 12 and the vehicle body 12 in order to deploy the vehicle. The center of the hinge pin 14 is at the height of the center point between the lower surface of the right floating body 13 (which becomes the upper surface when unfolded) and the upper surface of the vehicle body 12, and is located near the right side surface of the vehicle body 12 at the front and rear of the vehicle body. A left floating body 20 having a width approximately equal to the width of the vehicle body is installed above the right floating body 13, and is rotatably coupled to the vehicle body 12 via a hinge pin 21 and pin receivers 22, 23. Also, in order to expand this, a cylinder 24,
An arm 25 and a cylinder 26 are provided between the arm 25 and the vehicle body 12. The center of the hinge pin 21 is at the height of the center point between the lower surface of the left floating body 20 (which becomes the upper surface when unfolded) and the upper surface of the vehicle body 12, and is located near the left side surface of the vehicle body 12 at the front and rear of the vehicle body. 27 is a land traveling device, and 28 is a water propulsion device.

FIG. 9 is a cross-sectional view of the water bridge attitude with the left and right floating bodies developed in the same cross section as in FIG.
0 and the car body 12, 31 is a metal fitting for connecting the floating body of the adjacent car body, and 32 is a receiving metal fitting. 3
3 indicates the water surface. In FIG. 9, the lower surface of the car body 12 and the lower surfaces of the floating bodies 13 and 20 are not on the same plane, but they can be made on the same plane by reducing the height of the car body and increasing the height of the floating bodies. However, the necessity, advantages, and disadvantages thereof are not directly related to the present invention, so their explanation will be omitted.

Figure 10 is a plan view when the floating bridge is configured, and Figure 11 is a front view of the same.
and each vehicle body 12, floating body 13,
The upper surface of 20 forms a continuous passage surface 34. At the end of the floating bridge, the lower surface of the floating body 20 can be grounded to allow passing vehicles to ride onto the floating body 20 from the riverbank.Furthermore, as shown in FIGS. Combine 35,
It is also possible to allow passing vehicles or the like to board from the river bank 36 without touching the lower surface of the floating body 20 to the ground. In addition,
A water propulsion device 28 is used to hold the floating bridge against the water flow.

According to this embodiment, the width of the vehicle in the bridge position with the floating body deployed can be increased to about three times the vehicle width in the land position, and the upper surface of the vehicle body and the upper surfaces of the left and right floating bodies can be made on the same plane, and the width of the vehicle can be This has the effect of directly connecting the floating bodies and forming a continuous passage surface on their upper surfaces.

Therefore, according to the above configuration, the width of the entire floating bridge when the floating body is deployed can be significantly increased, so that the floating bridge can be constructed with a relatively small number of vehicles. In addition, by making the upper surfaces of the car body and the floating body on the same plane as a passage surface, and directly connecting the floating bodies of adjacent vehicles to form a continuous passage surface,
There is no need for a separate structure, and only the vehicle body and floating body provide buoyancy against the load of passing vehicles.
It can also serve as a passageway, and the structure can be simple and lightweight. This improves maneuverability on land and water, and eliminates the need for operations and time to move a separate bridge body, reducing bridge construction time and personnel requirements.

As explained above, according to the present invention, it is possible to form a floating bridge with a relatively small number of people by widening the width when unfolded.
In addition, the structure is simplified by using the floating body and the upper surface of the vehicle body as the passage surface.
