Description

Device for horizontal discharge of vehicles.

Object of the invention

The present invention relates to a device that has been specially designed to facilitate the unloading of vehicle boxes such as trucks, intended for the loading of materials.
them.

The object of the invention is to provide a device that allows said discharge to be carried out horizontally, with simple structuring, minimum volumetric occupancy, and high efficiency.
Inc.

Background of the invention

In the practical scope of the invention, devices for horizontal emptying of truck boxes in which the front or element that acts as load pusher is directly displaced by a hydraulic cylinder, so that it must be placed by behind that element, with the consequent and negative impact that this supposes at the level of volumetric occupation, consequently reducing the load capacity of the truck.

Description of the invention

The device for horizontal discharge of vehicles proposed by the invention fully solve satisfactory the aforementioned problem, thanks to a Simple solution structurally, but of great efficiency.

To do this the device that is recommended centers its characteristics in the fact that the front or element load pusher, the one intended to move horizontally on the vehicle cargo box, it is arranged on a rack or car which is moved along said box by means of a cable and pulley system driven by a cylinder hydraulic.

More specifically, to the extensible stem of the hydraulic cylinder is integral with a set of pulleys for which they are through two sets of cables, in opposite arrangements, for traction of said car in one way or another, so that the extension of said cylinder will cause the displacement of the cited car in the direction of emptying the vehicle while its retracted will cause the opposite movement of the car.

The drive of said cylinder is perform using a simple lever set in one place appropriate outside the vehicle, so that said mechanism It can be easily used by unqualified personnel.

Regarding the configuration of the element pusher, this will present a curved geometry, so that its upper limb extend steeply into the vehicle box, in order that during the movement of said element, the material that tends to move superiorly through accumulation on said element again fall by gravity to inside the box, avoiding its exit.

A device is thus achieved for extremely simple, fast, efficient vehicle unloading, economic and that allows to optimize the load capacity of the vehicle.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to an overview in perspective, and schematically, the basic elements that participate in the movement of the car of a device for the horizontal vehicle unloading done according to the object of the invention.

Figure 2.- Shows the assembly of figure 1 according to a perspective view opposite to that of said figure.

Figure 3.- Shows, finally, the set of figure 2, in which on the car appears the pusher element.

Preferred Embodiment of the Invention

In view of the figures outlined, and in special figure 1, can be seen as the device that The proposed invention is constituted from a carriage (1), longitudinally movable on the surface of the box concerned cargo vehicle, car (1) to which they are associated a pair of cables (2-2 ') on one of their faces for traction thereof in said direction, specifically on its ends (3-3 '), while on the opposite side another pair of cables (4-4 ') is fixed, in this case at the middle level of it.

The pair of cables (2-2 ') is Associates a set of pulleys (5) whose axis of rotation is integral to the extendable rod of a hydraulic cylinder (6), set under the load surface of the vehicle, for which said cables are driven to said position through pulley sets (7), fixing at its other end (8) to the chassis (9) of the vehicle.

Similarly, the pair of cables (4-4 ') are associated with the pulley set (5), being said cables also guided through a set of pulleys (10) established on the anterior area of the cargo box of the vehicle, cables that are fixed at its other end (11) to the chassis (9 ') of the vehicle.

So, and from the initial situation shown in the figures, when the cylinder rod (6) is extends the longitudinal displacement of the set of pulleys (5), which causes the cables (2-2 ') pull the carriage (1) by moving it in the direction of unloading of the vehicle while the pair of wires (4-4 ') moves over the pulley set (5-10) without applying any effort on said car, so that once the contents of the vehicle have been emptied the refolding of said cylinder (6) causes the cables (4-4 ') pull the car (1) on its face opposite, through the pulley set (10) bringing it into position initial, while in this operation the pair of cables (2-2 ') are only positioned in such a way that be ready to drive from said car in the opposite direction when necessary.

Finally, and as already noted with Previously, it should be noted that the car (1) will be associated a pusher element (12), embodied in an element laminar, whose radius of curvature decreases from its end inferior to its upper end, and that allows the material to store to move superiorly by accumulation on said element falls back by gravity into the box, avoiding the exit of the same towards zones of the truck no desired.

Claims (3)

1. Device for horizontal unloading of vehicles, which being of the type of those incorporating a carriage to which a pusher element of the load contained in the vehicle is associated, carriage movable longitudinally on said loading surface, characterized in that it incorporates a hydraulic cylinder established under the aforementioned loading surface, to whose extendable rod a set of pulleys is associated with which two pairs of cables collaborate, which by means of respective sets of pulleys are associated to the front and rear face of said carriage for movement thereof in one and other
sense. 2. Device for horizontal unloading of vehicles, according to claim 1, characterized in that one of the pairs of cables is fixed to the rear face of the car on the ends thereof, while the other is in the middle area of the front face . 3. Device for horizontal unloading of vehicles, according to previous claims, characterized in that the pusher element is embodied in a curved laminar element, whose upper extremity extends into the vehicle's loading surface.
