Description

Self-leveling coupling base.

Object of the invention

The present invention relates to a basis of self-leveling coupling applicable to industrial machinery and agricultural of the type composed of a chassis, on whose base it they mount the corresponding implements or accessories.

The object of the invention is to achieve a base self-leveling coupling that can be tilted so automatic to ensure the horizontality of the set to which dock

Background of the invention

Nowadays they are frequently used rigid coupling bases that do not allow its inclination in front of uneven terrain and obstacles. Consequently, at attach a set to the base, the horizontality of said set It is not insured.

The current regulations applicable to this type of machines, forces to have security measures that they block the machine when there is an unevenness in the set of the machine, in order to avoid accidents due to possible overturns.

The proliferation of machines that work in uneven terrain due to irregularities or obstacles same, has created the need for a docking base self-leveling that allows the work of the whole machine on land with slopes greater than 5%.

The applicant is unaware of the existence of any self-leveling coupling base as described in the memory detailed below.

Description of the invention

The coupling basis proposed by the The present invention satisfactorily resolves all the problematic previously exposed, constituting an element safe and reliable in its use in machines that work on land with unevenness due to irregularities or obstacles.

The self-leveling coupling base comprises two bases, one upper and one lower, joined by a system of articulation and assisted by hydraulic cylinders that allow to maintain the horizontality of the set in situations of unevenness

The invention focuses primarily on the system used to achieve the articulation of all the bases. The articulation system is composed of a structure constituted by two axes arranged in the form of a cross, and two, or more, articulated hydraulic cylinders at their ends.

The cross-shaped structure consists of two  tubes firmly attached to each other and arranged in the shape of a cross, which at their ends are articulated to their respective base, by means of a pair of tabs that emerge towards the inside of the bases, provided with two holes that allow the movement of Turn of them. The tabs are firmly attached to the respective base.

Hydraulic cylinders, articulated in their ends, are located so that when expanding and contracting cause the rotation of one or both axes that make up the cross-shaped structure. In this way, the upper base can change its inclination and therefore ensures at all times the horizontality of this base, and extensively of the set to which is coupled.

The expansion and contraction movement of hydraulic cylinders is governed by an electronic system or hydraulic linked to an inclinometer that automatically actuates each of the cylinders to provide the horizontality of the base continuously.

The self-leveling docking station is equipped with all the necessary security elements for a use and  safe operation

The self-leveling coupling base described It has numerous advantages over the current bases of coupling used in different types of machines. Is a Easy construction base, easily adapts to all types of machines and provides the set to which it is most coupled operability and security, since it allows maintaining the horizontality of the set in situations of unevenness.

From the point of view of the safety of people this self-leveling docking station features numerous advantages. It has a programmable inclinometer connected to a alarm and safety valves in hydraulic cylinders.

It is also advantageous, that this basis of self-leveling coupling allows to place in one of the bases a mechanism capable of producing the rotation of the entire base of self-leveling coupling, such as a crown assembly Toothed-pinion.

Description of the drawings

To complete the description of the invention that is being done and in order to help a better compression of the features of the invention, in accordance with a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a perspective view of the self-leveling coupling base.

Figure 2.- Shows a perspective view of the cross-shaped structure and the lower base of the set of the self-leveling coupling base.

Figure 3.- Shows the front view of the self-leveling coupling base.

Preferred Embodiment of the Invention

In view of the figures outlined and in special to figures 1 and 2, it is observed as the upper base (1),  articulated centrally by a cross-shaped structure (2), can tilt automatically by means of two or more hydraulic cylinders (3).

Optionally, when required, allow Rotation of the entire self-leveling docking base, you can install a mechanism in the lower base (4) or in the upper one (1) capable of producing the turning movement, such as a gearwheel-pinion assembly, not shown in the drawings.

The self-leveling docking station is characterized by having an articulation system capable of maintain the horizontality of the upper base (1).

The articulation system is composed of a structure consisting of two axes arranged in the form of cross (2), and preferably by two hydraulic cylinders (3) articulated at its ends by kneecaps (5).

The cross-shaped structure (2), for the present embodiment, is composed of two tubes (6) firmly attached to each other and arranged in the shape of a cross, which in its ends are articulated to the respective bases (1) and (4) by means of a pair of tabs (7) that emerge towards the inside of the bases, provided with holes that allow the movement of Turn of them. The tabs (7) are firmly attached to the  respective bases (1) and (4).

Hydraulic cylinders (3), articulated in its ends by ball joints (5), are located so that at expand and contract cause the rotation of one or both axes (6) that make up the cross-shaped structure (2). Sayings Hydraulic cylinders (3) are automatically governed by an electronic system linked to an inclinometer, not represented in the drawings.

In Figures 3 and 4, you can see the operation of the self-leveling docking station. At moment when the lower base (4) loses horizontality, the hydraulic cylinders (3) contract or expand in a way automatic and as necessary, causing the turning movement of the axes (6) that are part of the cross-shaped structure (2), in this way, the upper base (1) can change its inclination and therefore ensures at all times the horizontality of the upper base (1), and extensively of the set that may have been subject to it.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications as long as they do not alter the fundamental principle.
