nent 1983 edition, pages 828 and 829 of the 1983 edition, when the rear wheels of the transport vehicle go into the water to the extent that the transport vehicle retreats at the water's edge, and the water depth at the rear end of the transport vehicle becomes deep, the floating body is removed from the rear end of the transport vehicle. Floating bodies are known to be lowered into the water by being dropped, and also to be loaded by lifting the floating body with an on-vehicle crane after the rear wheels of the carrier enter the water. However, in this case, there is a problem in that the bearing capacity of the ground at the water's edge and underwater is significantly reduced on a weak riverbank, making it difficult for the transport vehicle to move forward and escape from the water's edge.

As described on page 72 of the 2016 edition, the floating body is loaded onto a trailer, backed up, and when the water at the rear end of the trailer becomes deep, the frame of the trailer is tilted and the floating body is slid down into the water. There is also known a device that is loaded by the reverse operation. However, in this case, since it is a trailer system, the overall length of the vehicle when traveling on land becomes large, and there is a problem that mobility on the road is impaired. [Object of the Invention] The object of the present invention is to enable a floating body to be lowered into the water even if the transport vehicle does not go into the water at the river bank, and to load it onto a continuous shooting vehicle from underwater, and to improve the efficiency of the vehicle when traveling on land. It is an object of the present invention to provide a floating body loading device which reduces the overall length and a method for constructing the same. [T+1 essential points of the invention] The present invention provides a slide that can extend and contract and tilt in the space between the chassis of a transport vehicle and the loaded floating body, and the space in the height direction of the slide is reduced. This structure allows the floating body to be smoothly and stably placed on the slide and moved during sub-loading operations. [Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 11. Figure 1 is a side view of the lower part of the floating body, and Figure 2 is A of Figure 1 below.
- In the cross-sectional view taken along line A, a slide 5 is provided on the chassis 2 of the transport vehicle 1 via an elevation shaft 3 and a hydraulic cylinder 4. The slide 5 has an outer rail 6 and an inner rail 7 that is extendable and retractable.
Consists of. A roller 8 is provided on the upper surface of the outer rail 6, and rollers 9, 10 are provided on the upper surface of the inner rail 7, and the loaded floating body 11 rolls thereon in the direction of the arrow and is lowered into the water from above the transport vehicle 1. At the time of transportation, the transport vehicle 1 is on land as shown in FIG. When the floating body 11 plunges into the water, it is extended underwater to a position where the necessary water depth is obtained and is grounded on the river bottom. A roller shaft is provided at the bottom of the end surface of the floating body 11, so that when one end of the water side of the floating body 11 leaves the slide 5 in the water and starts floating and reaches the state shown by the two-dot chain line, one end of the land side of the floating body 11 can move on the slide 5 using rollers. When the floating body 11 is loaded onto the slide 5, the rollers 12 completely move the floating body 11 to the rollers 8, 9, etc. on the slide 5.
It is also used to support and roll one end of the floating body 11 on the land side until the floating body 10 is cut. 13 is a winch for lifting the floating body 11 when it is loaded. In Fig. 2, in order to obtain large buoyancy and trackbed width as a floating bridge, the floating body 11 needs to have a width that is considerably large compared to the vehicle width as shown in the figure, but as will be explained later, this is not the case when traveling on land. Fold it and make a small sound. Figure 9JS3 shows the plan view of Figure 1. The slide 5 is composed of the above-mentioned outer rail 6, inner rail 7, rack gear 14, inner rail extension/contraction drive device 15, and a crossbeam 16 connecting the left and right outer rails 6. Figure 4 shows C-C in Figure 3.
It shows the details of the line cross-section and at the same time shows the details of section 8 of FIG. The outer rail 6 has rollers 8 that support the floating body 11.
is rotatably provided, and rollers 9 and 10 are rotatably provided on the inner rail 7 provided in parallel therewith. When the inner rail 7 of the slide 5 is extended, the floating body 11 is supported by either the rollers 8 or rollers 9 and 10. The rollers 8 and 9.10 have 7 lunges, and the left and right movement of the floating body 11 is controlled by sandwiching a rail 17 provided on each side of the lower surface of the floating body 11 between the flanges of the left and right rollers 8 and 9.10. I'm restrained. The inner rail 7 has a plurality of rollers 18 arranged in the front and back direction on both left and right sides of the lower part. 19, and when this is fitted (formed at the bottom of the outer rail 6)

The left and right sides are independently supported by the outer rails 6 by means of the [ ) guide rails. 16 far across. The outer rail 6 and the crossbeam 16 are connected to the carrier chassis 2 via the elevation axis 3.
Installed to. A rack gear 14 is fixed over almost the entire length of the inner moss of the inner rail 7, and its upper surface serves as a tread for a roller provided at the lower end of the floating body 11. The rack gear 14 is driven in the backward direction by the rotation of the inner rail extension/retraction drive device fixed to the outer rail 6 or the crossbeam 6 and the binion gear B connected thereto, thereby causing the inner rail 7 to extend or retract. 5-7 show other embodiments of the inner rail drive portion shown in FIG. 4. In Fig. 5, the flanges of the rollers 8, 9, and 10 are all placed in the same direction (in this case, both are on the outside), and in Fig. 6, the flanges of the roller 8 are placed on the inside, and the flanges of the rollers 9, 10 are placed in the same direction. A flange is provided on the outside. In contrast to the one shown in FIG. 4, in FIG. 7, rollers n with flanges that fit into guide rail devices provided on the outer rail 6 are arranged in parallel with rollers 12 on both front and rear end surfaces of the floating body 11, and one roller n is installed in each of the front, rear, left, and right directions. In addition, rollers 9 are not provided on the inner rail 7, and rollers 10 are provided only at one location each on the left and right of the tip. Next, the operation will be explained with reference to FIGS. 8 to 11 and FIGS. 1 and 2. FIG. 8 is a side view of the land traveling state, and FIG. 9 is a cross-sectional view of FIG. It is closely attached to the chassis 2, and a floating body 11 is loaded thereon via rollers 8 or 12. The cross section of the floating body 11 is shown in Figure 9 below, for example, it is divided into 5 parts horizontally into 3 parts.
By not folding it into stacks, etc., the width dimension B and height dimension H, which are restricted when traveling on land, are kept within the limits. Here, in order to keep the height H within the limit, the height h of the slide 5 must be made as small as possible. When traveling on land in this state and reaching the bridge point, the slide 5 is extended and tilted, and the floating body 11 is thrown into the water by its own weight as shown in FIGS. 1-2 described above. here,
In the embodiments shown in FIGS. 4 to 6, when the floating body 11 is completely on the slide 3, it is initially supported by the rollers 8 of the outer rail 6, and as it descends, it is supported by the rollers 9 and 10 of the inner rail 7. Ru. When the floating body 11 further slides down and begins to float as shown by the two-dot chain line in FIG. is supported by the rollers of the floating body ■. In addition, in the embodiment shown in FIG. 7, when the floating body 11 is completely on the slide 5, it is initially supported by the outer rail 6 by the rollers n at both the front and rear ends of the floating body U, and as it slides down, it is parallel to the rollers n. A roller hill provided on the floating body 11 is supported by the upper surface of a rack gear 14 fixed to the inner rail 7. Therefore, the rollers 8 of the outer rail 6 and the rollers 9 of the inner rail 7 in FIGS. When a-ra passes the tip of the rail 7, the water side end of the floating body 11 cannot be supported by the roller hill. It is set up. When the floating body 11 further slides down and the one end on the water side starts to float as shown by the two-dot chain line in FIG. 1, the one end on the land side of the floating body 11 is supported only by the rollers 12. In this way, after the floating bodies 11 are submerged in the water and bridged, the four bodies 11 are withdrawn and loaded onto the transport vehicle l.
lO, do as shown in Figure 11. FIG. 10 is a side view showing a loading state on a sloped riverbank similar to that in FIG. 1, in which a cable soffit is connected to a floating body 11 in a bridged state shown by a two-dot chain line, and is hoisted up by a winch 13 in the direction of the arrow. Slide 5 and rollers 8-1
The effect of 0.12 is the same as in the case of rejection in FIG. 1, and the operation is performed in reverse. Figure 1E11 shows that loading can be carried out on a stepped riverbank as well as on a sloped riverbank.Although I have omitted the illustration, the rejection on a stepped riverbank is the same as in Figure 11, and the opposite is true. This can be done through motion. If it is necessary to use a crane to move the floating body 11 in the water onto the transport vehicle l, please use the third method in advance.
It is assumed that the crane 2 is installed in the space between the slide 5 and the floating body 11 as shown by the two-dot chain line in Figure 4. According to the above embodiment, a slide that can extend and contract and tilt is provided in the small space between the transport vehicle and the loaded floating body, making it easy to dismiss and load the floating body, and to move the floating body away from the transport vehicle. This allows the river to be abandoned at a certain location, and is less constrained by riverbank conditions. Furthermore, since the outer and inner rails of the slide are arranged side by side, all the rollers can be made to have the same height, making it easy to move the floating body and transfer from the outer rail to the inner rail. Furthermore, since the inner rails are supported by the outer rails on the left and right sides, there is no need for crossbeams between the inner rails, and the upper surface of the rub gear is also used as a roller tread, so the overall height of the slide can be reduced and the carrier It becomes easy to keep the total height of the vehicle within the limit dimensions for road driving. If a floating body in the water needs to be hoisted onto a carrier by a crane, it is also possible to install the crane in the space between the slide and the floating body. In addition, since rollers are provided at the recovery end of the floating body in addition to the rollers of the slide, there is an effect that the floating body can be easily moved when one end of the floating body is floated during a battle. [Effects of the Invention] According to the present invention, it is possible to form a slide in a small space and extend the slide to a large extent, and the floating body rolls smoothly and reliably on the slide so as to be thrown into or out of the water. Since it can be loaded onto a transport vehicle, it is possible to dismiss or load the floating object at the river bank without the need for the transport vehicle to enter the water, making it easy to construct floating bridges on river banks with soft or stepped river banks. There is a certain effect. Furthermore, since the slide can be completely built into the transport vehicle, the overall length of the vehicle can be made smaller when traveling on land compared to the trailer system, making it easier to travel on the road.
