Description

[Detailed description of the invention] The present invention relates to the floor structure of containers and the like, and in particular, a floating floor is formed on a fixed floor via a cushioning material, and the floating floor is guided by a guide mechanism. The present invention relates to a floor structure for cargo transport vehicles such as containers that reduces vibration as much as possible.

Conventionally, when transporting cargo that is sensitive to shocks and vibrations, such as precision electronic products such as video cameras, by truck or trailer, the shock absorbers of these vehicles are generally hard, and the vibrations of the floor are directly affected. From the point of view of the cargo, strict packing and wrapping with sufficient cushioning material is required, or the traveling speed of the vehicle must be restricted, which increases transportation costs and reduces transportation efficiency. It was the cause.

The present invention was developed in view of the above circumstances, and includes a floating floor installed on a fixed bed via a cushioning material, and the floating floor being guided in the vertical direction by an id mechanism. The object of this invention is to provide a floor structure that prevents direct transmission of vibrations to cargo.

In order to achieve this objective, the present invention has a fixed floor and a floating floor positioned above the fixed floor for the floor on which cargo is to be placed, such as a container or the loading platform of a cargo transport vehicle. and a cushioning material disposed between the fixed bed and the floating bed to support the floating bed, and in contact with a side wall surface erected on the side of the floor. This is because a guide mechanism is provided that allows the floating floor to move freely in the vertical direction.

Thus, according to the present invention, the cushioning material is placed between the fixed bed and the floating bed, and the guide mechanism guides the vertical movement of the floating bed without contacting the side wall surface. , the floating floor is only allowed to move up and down, and movement in other directions is prevented.This effectively prevents direct transmission of vibrations from the floor, and the cushioning material reduces vibrations and shocks. effectively relieved,
Therefore, damage to the cargo due to this will be significantly reduced.

Therefore, there is no need for strict packing and packaging as in the past, making it possible to reduce packaging costs, and furthermore, the restrictions on traveling speed are relaxed, resulting in an excellent effect of improving transportation efficiency.

Hereinafter, a more detailed explanation will be given based on some embodiments shown in the drawings.

First, in FIG. 1, reference numeral 2 is an airtight pan body of a normal pan type truck, and a floating floor 8 is disposed on a fixed bed 4 constituting the lower surface of the pan body 2 via a cushioning material 6. It is being done.

That is, the cross member 12 fixed to the chassis frame 10 of the truck is provided with guide pipes 14 at appropriate locations, passing through the cross member 12 and the fixed bed 4, as shown in an enlarged view in FIG. is fixed, and on the other hand, a guide rod 16 is fixed at a position opposite to the guide pipe 14 on the floating floor 8, hanging down from the floating floor 8, and this guide rod 16 is guided by the guide pipe 14 to move the floating floor 8. can float vertically.

The cushioning material 6 is made of a plate-shaped sponge rubber or resin foam, and supports the floating floor 8 by its elasticity.

Further, the cushioning material 6 is only removably placed on the fixed bed 4, and even if it is on the floating bed 8, its guide rod 16 can be pulled out from the guide pipe 14 provided on the fixed bed. By doing so, it can be easily taken out from the floor.

With this configuration, when the floating floor 8 moves up and down with respect to the fixed floor 4 based on vibrations of the vehicle,
The guide rod 16 and the guide pipe 14 allow the floating floor 8 to move up and down, but prevent movement in the direction of the base, that is, in the front-back and left-right directions, effectively preventing lateral displacement of the floating floor 8. This prevents vibrations from coming into contact with the side wall surface (pan body 2) erected on the side of the floor and being transmitted therefrom.

Furthermore, the cushioning material 6 has the characteristics of an elastic body that effectively damps vibrations, and can effectively alleviate the vibrations of the floating floor 8, thereby significantly reducing damage to cargo caused by shocks and vibrations.

Therefore, there is no need for strict packing and packaging that incorporates sufficient cushioning material as in the past, and there is no need to limit travel speed to avoid damage from vibrations, reducing packaging costs. As a result, savings in transportation costs and improvements in transportation efficiency can be effectively achieved.

In addition, as in this example, the cushioning material 6 and the floating floor 8 can be simply replaced with the fixed bed 4.
By making it as if it were only placed on top, it is possible to remove it and use it as a general fixed bed. It also has the advantage of being able to carry.

Next, a floor structure provided with another cushioning material will be explained based on FIG.

In the figure, the floating bed 8 is movable relative to the fixed bed 4 by being guided in the vertical direction by a guide pipe 14 and a guide rod 16 as in the previous embodiment. An air mat 20 is placed and interposed as a cushioning material in place of the sponge rubber or the like of the previous embodiment.

The air mat 20 is equipped with a valve 22 that allows air to be taken in and out, similar to a car tire.

Therefore, adjustment of the buffer function, which was difficult in the previous embodiment, can be made extremely easily in this embodiment.

In other words, by increasing or decreasing the air pressure depending on the type of loaded item and the weight of the loaded item, it is possible to utilize the optimal cushioning effect for the loaded item.

Next, a floor structure equipped with yet another cushioning material will be explained based on FIG. 4.

In this case, a large number of coil springs 24 are interposed between the fixed bed 4 and the floating bed 8, and an appropriate number of guide rods 16 erected on the floating bed 8 support the guide pipes 14. After being penetrated, it is further connected to a buffer 26 at the lower end, and the lower end of the buffer 26 is connected to the cross member 12.
It is fixed to the lower surface of with a bracket 28.

Therefore, the vibrations of the floating floor 8 on which the load is placed are damped by the large number of coil springs 24 and the appropriate number of shock absorbers 26, and damage caused by impact and vibration of the load can be effectively prevented.

In addition, in this embodiment, the coil spring 24 and the shock absorber 2
6 has been shown, but a floor structure with only one of them is also possible.

Next, an example of a floor structure equipped with a guide mechanism other than a guide rod type will be described with reference to FIG.

In this case, a buffer material 6 is interposed between the fixed bed 4 and the floating bed 8, and a plurality of rollers 60 are rotatable by brackets 62 at the ends of the floating bed 8 on the side walls 28. The rollers 60 are guided by the side wall 28 so that the floating floor 8 can be moved up and down without fully contacting the side wall 28 surface.

In addition, in the floor structure according to the present invention shown in FIG. 6, a cushioning material 6 such as sponge rubber is laid on the fixed floor 4 in contact with both side walls 28, and a floating floor 8 is placed slightly apart from both side walls 28. It is placed on the cushioning material 6.

Therefore, while the floating floor 8 is cushioned by the cushioning material 6 when moving up and down, it is prevented from coming into contact with the side walls 28.

In particular, in the embodiment shown in FIGS. 5 and 6, the floating floor 8
Since the and buffer material 6 are simply placed on the fixed bed 4, there is no need to provide any members on the fixed bed 4, and they can be easily removed to return to the normal fixed bed 4. This is possible.

In other words, the floating floor can be used only when transporting cargo that is sensitive to vibrations.

In addition, as a means for fixing the cargo 35 to the upper surface of the floating floor 8, for example, as shown in FIG.
A number of floor rings 30 are fixed to the floating floor 8 along the longitudinal side walls 28 of the frame, through which load fixing ropes or belts 32 are inserted, so that the load 35 can be tightened through a holding plate 34. means are adopted.

Further, as shown in FIG. 8, a structure is used in which a large number of hooks 36 are arranged horizontally on both side walls 28, and these hooks 36 are connected to a presser plate 34 by a spring or a rubber belt 38. There is also a method of fixing the cargo 35 by using the method.

Note that a sponge sheet 4 for protecting the cargo 35 is laid on the lower surface of the holding plate 34.

On the other hand, as a tensioning means in the advancing direction, as shown in Fig. 9,
The lashing belt 44 is inserted through the hooks 42 provided on both side walls 28 and the cargo 35 is pushed forward, or as shown in FIG. The lashing beam 48 that is passed through the styrofoam 50 presses the cargo 35 forward.

In addition, in FIGS. 9 and 10, the cargo 35 is
The rack is pressed against the floating floor 8 via a holding plate 54 by a band 52 passed between hooks 36 and 36 provided on the rack.

Furthermore, in FIG. 10, a plurality of cushioning materials 6 are arranged between the fixed bed 4 and the floating bed 8.

Of course, it goes without saying that the cushioning material 6 can be placed between the fixed bed 4 and the floating bed 8 in one large, integral shape.

In each of the above-mentioned embodiments, the floor structure of a van truck was described, but the present invention is not limited to this in any way. It is also possible to adopt a similar floor structure in a normal cargo transport vehicle with a flat body with a tilt-and-swing mechanism.

In addition, the present invention may be modified in various ways based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
Needless to say, improvements can be made.
