Description

Large volume box for transport truck.

OBJECT OF THE INVENTION

The present invention relates to a box for transport truck, whose purpose is to load materials, mainly scrap, and be transported by the truck of which the box itself is part.

The object of the invention is to reduce costs in the manufacture of the high-volume and high-strength boxes mainly used for the transport of scrap metal, as well as to reduce their weight without diminishing the capacity, thus allowing to transport a greater quantity of scrap metal.

BACKGROUND OF THE INVENTION

For the transport of scrap special boxes are manufactured that are mounted on the chassis of the trucks, so that due to the type of material that is the scrap, the box as a cargo container must meet a series of requirements, being able to cite as more The following are relevant:

-

It must be capable of transporting the maximum volume of cargo, that is, of large volume, and having the minimum weight, in order to be as profitable as possible for the carrier.

-

It must always remain mounted on the chassis of the truck.

-

It must be flexible and very resistant, especially to the dents produced by the blows and pressure of the scrap metal.

-

It must produce the unloading by tilting of the own box, by means of piston or hydraulic pistons.

-

You must have a specially resistant floor to meet the above requirement.

-

It must allow the discharge of the scrap to slide easily on the inner surface of the box itself.

Well, to meet these requirements, the boxes are manufactured on the basis of first having a lower rib structure, then assemble and fix some side ribs, the assembly constituting a kind of rib cage to which they are welded inside flat plates to achieve closure and ultimately obtain the box, which comprises a base structure as the main element of resistance formed by the ribs and plates welded on the ribs of the floor and on the lateral ribs, as well as welded together plates.

As it is evident, the realization of the box requires a lot of work and effort, because in addition to the manufacture of the ribs and the sheets, it is necessary to carry out the welding, which implies arduous and expensive tasks.

On the other hand, junk boxes require a high number of ribs, which means an increase in the weight of the ribs, regardless of the economic cost.

They also have the disadvantage of not offering sufficient resistance to the dents to which the plates are subjected in the loading and unloading operations of the scrap metal.

However, it is known of the existence of boxes whose side plates have a curved profile, specifically obtained by successive bends or breaks, which provide high resistance and prevent the use of the classic side ribs, reducing the weight of the whole of the box, as well as the expensive work of manufacturing the ribs and making the corresponding welds.

However, these side plates require an upper beam to absorb shocks, the lower ribs of the base remaining in any case.

DESCRIPTION OF THE INVENTION

The box that is recommended has been designed to solve the above-mentioned problem of the use of ribs, based on the box with curved side plates, that is to say with longitudinal folds, and without side ribs.

From these characteristics, the box of the invention has the particularity that the lower plate is provided with a fold on each side, with an outward inclination and greater than 90 °, while the curved side plates have an angle on their lower edge different from the others that gives said plate a vertical finish and at the end it bends 90º inwards, leaving the wing that determines this lower bending of the lateral wings under the lower plate, determining with the wing folded outwards of the latter, a hollow constituting a lower tubular beam on each side, after the welded together of both plates.

However, the lateral folds and the lower tubular beam can be manufactured in other ways, as will be seen throughout the course of the present specification, without affecting the essence of the invention.

These lower tubular beams, in combination with the lateral curved plates and the upper beams of the lateral plates, avoid having to use stiffening ribs, both at the base and at the sides, which undoubtedly saves money, labor and of welds, as well as a decrease in weight of the box itself.

That is to say, by means of the referred innovation, the construction time of the box is significantly reduced, since this is simpler by suppressing the high number of ribs conventionally required, reducing the number of steps in manufacturing, and even allowing to carry out series manufacturing processes.

On the other hand, it should be noted that the box of the invention is constituted by high-strength wear-resistant steel sheet, thereby improving the box and multiplying the duration thereof.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the box (1) provided for the transport of scrap in trucks, on whose chassis it will be permanently mounted, is constituted by lateral curved plates (2), a lower plate (3) of base and front and rear closure plates (4), all joined together by welding.

The side plates (2) have a plurality of longitudinal folds, determining a broken profile with an upper longitudinal reinforcement beam (5) and with a lower right angle bending, determining a horizontal and lower wing (6) oriented inwards.

For its part, the lower plate (3) has its sides angled at an obtuse angle, determining inclined wings (7) projected outwards.

In the connection between the side plates (2) and the lower plate (3), those remain in respective external vertical planes with respect to the inclined and lateral wings of the lower plate (3), leaving the lower horizontal wing (6) of the lateral plates (2) located below the lower plate (3), so that when the plates (2 and 3) are welded together, determining hollow spaces of lower tubular beams (8), of triangular configuration, are formed in correspondence with the bottom.

However, it could be the bottom plate (3) that was bent at right angles defining a wing

vertical (9) and the wall being the one that remains angled, without affecting the essence of the invention.

The lower tubular beams (8), in combination with the special configuration of the sides (2) and

with the upper longitudinal reinforcement beams (5) of these, they constitute a high-strength, easy and safe housing

Quick to build and low weight having eliminated the classic side and lower ribs that include the

5 conventional boxes.

In addition, due to the shape and because the sheets are made of wear-resistant and resistant steel, the box (1) does not

it will suffer dents, since it has been proven experimentally that even introducing loads higher than

usual, the plates yield or flex laterally but recover their natural position when the load is removed.

Finally, to say that the effect provided by the lower tubular beams (8) is fundamental, since

10 that the load exerts at the base and on the sides of the box (1) a very large pressure that tends to bend the curved sheet that constitutes the sides (2), so that by means of these lower tubular beams (8) it is avoided largely that pressure effect.
