Description

Dump vehicle for transport in short distances and pouring of concrete and other materials semi-liquids

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a vehicle of mass concrete transport, mainly used in the construction of large civil engineering structures such as dams, bridges, etc; where there is a need for transportation and Pouring of this type of concrete. The characteristics of this and of its kneading are given by the action of the high and numerous loads to which these elastic structures are subjected.

In this way, the water used in kneading of concrete should be minimized compatible with conditions of the work, reaching the maximum resistance, generally, when the proportion of water is such that a light tamping is enough to make it reflux the entire surface, as this indicates that all the Air has been removed from mass concrete.

Starting from this premise, the object of the invention is a mass concrete transport dump vehicle oriented to achieve a process of downloading this material from a more efficiently, so that the immediate need is not necessary interior cleaning of the truck box to eliminate possible waste.

Another objective of the invention is to provide a greater stability to the vehicle, both in motion and in tilt

All this will result in a tool more versatile and efficient for the transport and dumping process of this type of materials (concrete and other materials semi-liquid) from its kneading to the place where It must be deposited and applied.

Background of the invention

At present, it is common for the kneading of Concrete is carried out in the work itself. This shape, the necessary path from the kneading place to the place where the concrete has to be poured is a relatively distance short. In addition, the use of vehicles for transportation is desirable. of concrete instead of conveyor belts to reduce maximum amount of water, in order to reach a resistance maximum of the mixture, and provide the transport system with a greater geographical mobility for the work.

There are few alternatives today for this type of vehicles, which could be referred to as dump trucks concrete and other types of semi-liquid materials. In general, you are Alternatives are based on rigid vehicles with a tilting box open at the top, whose shape is designed to favor the emptying of this type of mass.

They are boxes formed by two lateral planes vertical with a conical bottom, that is, a round bottom whose radius is reduced to the rear, higher, and that is by which the download of the material is done. They can incorporate a rear hatch to regulate the discharge process of the material.

The tilting axis is located in the rear of the vehicle and the unloading is carried out by means of the actuation of a hydraulic lift cylinder located in the lower part of the tilting box, whose thrust is made on the lower part thereof, said cylinder being coupled in the own base structure of the vehicle.

All these models have different limitations cited below.

The first one is that the download of material is not complete, in the sense that after downloading part of it remains adhered to the longitudinal edges defined by the union of the lateral planes and the bottom bottom of the box, and the base of the front wall of the box with said bottom lower.

Thus, the cleaning of the box is necessary, both before these residues set as the following loading of material, so that the times between pouring and pouring of the material are increased by the amount of time consumed in The cleanliness of the box.

In addition, the use of the basculation system based in a lower hydraulic lift cylinder makes the vehicle require special conditions of the road through which it passes and / or pour the concrete in mass, so that the firm must be especially flat so that all wheels are practically in the same totally horizontal plane.

Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a vehicle for transporting and pouring concrete into mass that includes in principle: a tilting box containing the mass concrete whose special shape improves its pouring; placed on a base structure, overframe, which supports it and on which the transport efforts and the tilt; while a lifting mechanism is included for Tilt such a box in a more stable way.

It is characterized because the tilting box understands:

-

He Tilting box design is based on the longitudinal union of: a toriespheric bottom attached to a body or cylindrical ferrule, which they share the same common axis bottom-ferrule, and this one to in turn it is attached to an oblique trunk-conical body by the greater base of this one, whose common axis bottom-ferrule is aligned longitudinally according to a plan view with the common axis bottom-ferrule and inclined vertically according to a elevation view with respect to said common axis bottom-ferrule.

-

Is open at the top and its tilting axis is in the rear end, discharge end.

In this way, you get: a) eliminate the longitudinal edges and b) accumulate along the tilt of the box a large mass of the product in the front of the same, bottom-ferrule.

During product download, the tilting box and having eliminated the longitudinal edges, it cannot adhere along its surface route inside of it.

In addition, the fact of having managed to accumulate a much larger mass ratio at the opposite end of the area discharge (rear area), causes during the tilting of the box the product slides with greater force, due to the force of thrust that said mass exerts on which it is located in the area rear of the box.

This same thrust force during the tilt of the accumulated mass in the front, bottom-ferrule, it is enough for the product overcomes the opposition of the two transverse edges (corresponding to the union of the three bodies) in its path by the tilting box towards the discharge end.

The use of a fund ensures that there is mass enough of the product to drag with enough this force to overcome the first transverse edge and serves as reinforcement of the front wall of the box.

Both the maximum tilting angle, he of inclination of the axes of the bodies that make up the shape of the tilting box, as the shape of this one makes the discharge of product is fully produced, without the need for any type of additional system for this and without the need for cleaning possible remains after the product was spilled, making this process, therefore, in a more efficient way.

Another feature of the invention is that the tilting mechanism of the tilting box comprises a Hydraulic front attack lifting cylinder.

A hydraulic attack lift cylinder front requires less effort to perform the tilt of the box, which means lower hydraulic pressure, lower dimensioning of support points, ... which has a minor impact wear of the system component set.

In a tilting system, one of the points critics of the burden sharing study takes place when the fair system begins to swing, since at that moment the load does not it has started to download and therefore it is distributed completely between the support points of the tilting system: clamping the hydraulic lift cylinder to the chassis and clamping of the tilt axis.

Thus, when the tilt begins in a tilt system with hydraulic attack lift cylinder bottom and with the tilting axis located in the rear area of the vehicle, all cargo is concentrated at a point located behind the last axis, producing a push back and forth from he. This causes great instability in the vehicle, since it loses support force at the points for which it was designed, in special on the front wheels of it.

In this way, the risk of overturning is quite elevated with any change in the ideal conditions in which the vehicle must be positioned for tilting: be located in a practically horizontal plane. In addition, this fact may become a functional limitation of this type of systems if it is desired to spread the load, not at a point, but along a path, for which it is necessary that the tilting of the box is perform with the vehicle moving.

On the other hand, in a tilting system with hydraulic cylinder of front attack and with the axis of tilting located on the last axle of the vehicle, when it starts tipping, load sharing is distributed in a more uniform between the front and rear of the vehicle, providing the vehicle for greater stability and thus reducing the risk of dump it in any of the above situations.

Another feature of the invention is that the tilting box incorporates a stabilizing scissors mechanism connected to the base structure and initial part of the flat bottom tilted tilt box for better stability of it, essentially during its tilting.

The stabilizing scissors system allows distribute the effort suffered by the tilting structure in case of possible transverse torsions while the box weighing machine. These twists are due to a transverse displacement of the center of gravity of the mass of the product with respect to the axis longitudinal of the box. This situation may be caused by the location of the product itself in the box after the loading process or for carrying out the downloading process of the latter not being the vehicle in a completely horizontal plane.

Another feature of the invention is the incorporation to this type of side stabilizer vehicles, which allow the system to provide the necessary stability when it requires that the download of the product be carried out in places in which, the vehicle's own points of support are not enough so that the risk of overturning it is considered to have a acceptable security value.

Another feature of the invention is that the joint system is designed to be coupled on a vehicle rigid, a semi-trailer or a trailer, when it is placed on an overdrive. This allows you to adapt to a multitude of possibilities, from the point of view of the type of vehicle that best suits the needs of transportation and dumping of this type of materials

Finally, the discharge regulation is carried out by the tilting angle of the box and the opening of a rear hatch placed at the end of discharge.

In this way, the proposed tilting system, the design of the shape of the box and the change in the system of tilting used so far in this type of vehicles, supposes really a technical improvement in tippers of this type of products, as it improves all existing functionality previously.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the mass concrete transport and pouring vehicle and semi-liquid materials comprises a characteristic tilting box 1 whose design favors the unloading of the product of A more efficient way.

The tilting box 1 has a structure open at the top, whose tilting axis 2 is located at the corresponding rear end with the discharge end of the concrete material, highlighting that such a tilting axis 2 is is elevated above the base structure, overframe 3 of the vehicle, in correspondence with a convergent rear up and back of the tilting box 1. To do this, you includes a support 4 for the tilting axis 2, integral with the overframe 3 of the vehicle and on which articulates the box swingarm 1 at its rear end, corresponding to the axis Tilt 2.

The tilting box 1 comprises the union longitudinal of:

-

a 6 toriespheric bottom attached to

-

a cylindrical ferrule 5, which share the same common axis, common axis bottom-ferrule 7, and this in turn is attached to

-

a oblique trunk-conical body 9 by the major base of this one, whose axis, axis of the conical trunk 8, is it is aligned longitudinally according to a plan view with the common bottom-ferrule axis 7 and inclined vertically according to an elevation view with respect to said axis common bottom-ferrule 7.

In addition, characterized in that the minor base of the oblique trunk-conical body 9 defines a mouth output 12 of the material.

This design, object of the invention, does not there is no longitudinal edge in the shape of the tilting box one.

In this outlet 12, you will find an articulated rear hatch 13 to regulate the output flow of mass concrete. So, when you do the tilting of the tilting box 1 for emptying the concrete in bulk, said articulated rear hatch 13 tilts out and is pushed also partly by the product itself, allowing the emptying of the same.

The upper open structure of the box swingarm 1 defines an upper opening arranged in a plane horizontal when the tilting box 1 is in the position of repose.

The tilting of the tilting box 1 is performs using a hydraulic lift cylinder 15 attack front coupled, therefore, in an anterior part of the overdrive 3 of the vehicle, while also connecting articulately with the front wall of the bottom 6 of the tilting box 1, by means of a pair of lugs 10 integral to said front wall.

To achieve better stability during tilting of the tilting box 1, a mechanism of stabilizing scissors 11 that connects to the overdrive 3 of the vehicle and with the bottom surface of the tilting box 1.

Finally, it should be noted that the vehicle of the invention also incorporates rear stabilizing legs 14 to stabilize the vehicle assembly during tipping of mass concrete, mainly in soils where The vehicle's own points of support are not enough to that the risk of overturning of this is considered to have a value acceptable security.

Both the maximum tilting angle, he of inclination of the axes of the bodies that make up the shape of the tilting box, as the shape of this one makes the discharge of product is fully produced, without the need for any type of additional system for this and without the need for cleaning possible remains after the product was spilled, making this process, therefore, in a more efficient way.
