Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stuttering adjustment device for an amphibious vehicle.

(Prior Art) As shown in Fig. 7, in an amphibious vehicle A which obtains buoyancy by a vehicle body a and wheels and tires b, the surface of the water line C has a complicated uneven shape, and the vehicle body a The length of the IAC fluctuates greatly due to fluctuations in the IAC. Also, due to the structure of the vehicle body a, when people are on board or cargo is loaded on the cargo platform d,
The center of gravity tends to be higher than the center of buoyancy of the vehicle in the water, making it more unstable to drive on water than a normal ship.

FIG. 8(a) shows the amphibious vehicle A in an upright state, and in this state, the left and right sides are evenly hunched as indicated by diagonal lines in FIG. 8(b).

However, when the slope is moderate as shown in Figure 9, the water surface is biased to one side (to the left in the figure), and when the slope becomes even larger, the water surface is biased to the right, resulting in an extremely unstable condition.

(Problems to be Solved by the Invention) To maintain a vehicle body horizontally on water even when the cargo is unevenly loaded. In other words, we have developed a device that can improve the ability to recover on water even when the center of gravity rises due to cargo, and also allows the g* of the waterline to be suitable for landing on sandy or muddy ground from the water. The purpose is to provide.

(Means for solving the problem) Vertical position adjustment racks are fixed to both sides of a gate-shaped support frame provided on both the front and rear sides of an amphibious vehicle.

It consists of two left and right floaters that are removably attached to this vertical position adjustment rack via a floater support rod, and the floater support rod has one end attached to a two-part mounting bracket and the other end attached to a lower mounting bracket. The upper mounting bracket can be adjusted up and down with respect to the vertical position adjustment rack, and the lower mounting bracket can be adjusted in front and back and left and right positions with respect to the adjustment rack attached to the top surface of the floater, and can be attached and removed. It can be installed on.

The floater and support rod can be stored at the top or front of the vehicle.

(Example) This will be explained based on the drawings. FIG. 1 shows an amphibious vehicle (hereinafter referred to as vehicle) in which the present invention is implemented. Six wheels 1 on the left and right serve as propulsion devices when on the water. A floater 2 is attached to a pair of front and rear gate-shaped support frames 3 fixed between both sides of the loading platform of the vehicle A.

4 is the upper and lower floater i fixed to the side of the support frame 3
The adjustment rack is provided with a plurality of holes 4a in the vertical direction.

The floater 2 has a warped shape and consists of two pieces on one side (one on each side).
(Of course, it is also possible to use it with a book), three floater support rods (hereinafter referred to as support rods) at the front and rear (hereinafter referred to as support rods) 5a, 5b
, 5c. The three support rods 5a to 5C are pin-coupled at both ends to an upper mounting bracket 6a and a lower mounting bracket 6b, respectively. And L part mounting bracket 6
a is attached to the hole 4a of the vertical position adjustment rack 4 with a bolt so that the vertical position can be adjusted. Also, lower mounting bracket 6
b is attached to the longitudinal and lateral position adjustment rack 7 between the two floaters 2. The front/rear/left/right position adjustment rack 7 is composed of a front/back position adjustment bracket 7a fixed to the upper surface of the two floaters 2 in the longitudinal direction, and a left/right position adjustment bracket 7b orthogonal to the front/rear position adjustment bracket 7a, and the left/right position adjustment bracket 7b is a front/rear position adjustment bracket. The front and rear positions of the bracket 7a can be adjusted, and the bracket 7a is positioned by inserting bolts into a number of holes provided in the bracket 7a.

To adjust the left-right position, slide the lower mounting bracket 6b relative to the left-right position adjustment bracket 7b, and position it at the appropriate position by inserting a bolt into a hole provided in the left-right position adjustment bracket 7b.

Of the three support rods, one support rod 5a is pin-coupled to the upper end of the upper mounting bracket 6a and the outer side of the lower mounting bracket 6b. The other two support rods 5b and 5c are pin-coupled to the lower end of the upper mounting bracket 6a, and the other end is pin-coupled to the inner and outer sides of the lower mounting bracket 6b, respectively, and once they are fixed after positioning, they are firmly fixed at that position. It is now possible to do so.

Reference numeral 8 denotes a floater storage rack, which is fixed to the top of the support frame 3, and when the floater 2 is not in use, it is stored there using a floater front/rear left position adjustment rack (FIG. 2). 9 is a floater support rod storage rack, and the support rods 5a, 5b,
5c is disassembled and stored here as shown in FIG.

(mWJ of floater according to cargo load> Now, Fig. 3 shows the installation state of the floater under light load. In this case, floater 2 is installed one on the left and one on the left. On the other hand, under heavy load, As shown in the figure, two floaters 2 on the left and right sides are installed to support heavy loads.

(Adjustment of the floater in case of uneven load) When the load is evenly distributed on the loading platform as shown in Figure 5 (a), the left and right floaters 2 are at the front, and the center of gravity of the load is biased toward the rear on the loading platform. In this case, the floater 2 is adjusted by shifting it backwards as shown in FIG. 5(b).

The stiff floater can be increased or decreased or adjusted in its longitudinal position by using the holes in the upper and lower wvas racks 4 and the longitudinal and lateral position adjustment racks 7.

(Setting a shallow hiatus depending on the water/land soil quality) In this case, the height of the floater for the standard hiatus is as shown in Figure 6 (a), and when the height of the floater is shallow as shown in Figure 6 (b), the vertical position adjustment frame 4 is Lower the upper mounting bracket 6a to make it easier to generate buoyancy.

The floater of the present invention can also be applied to small-sized transport vessels used at small and medium-sized underwater civil engineering construction sites such as lakes, marshes, and rivers. It is also possible to run at high speed without installing a floater when the load is light, and to provide a stable restoring force by installing the floater only when the load is heavy.

(Effect 9) The floater can be attached to both sides of the amphibious vehicle via support rods.The position of the floater can be adjusted up and down, forward and backward, and left and right. This allows you to keep the vehicle level.

2) Even if the center of gravity increases due to cargo, the ability to recover on water can be improved.

3) Also, when landing on sandy or muddy ground from the water, the water line can be adjusted, making it possible to run smoothly under optimal conditions.

4) Furthermore, when not in use, the float and its support rod can be disassembled and stored at the top or front of the vehicle, making it convenient and out of the way.6
