Description

"PLATFORM BALANCE

RODOVIÁRIA OR RAILWAY AND RESPECT OF THE PROCESS OF CONSTRUCTION IN LOCO ".

FIELD OF INVENTION

The present invention, which is in the field of mechatronics, is a platform scale and its respective on-site procurement process, which is intended for weighing road or rail vehicles and can be used in commercial or industrial activities that require weighing large volumes of cargo.

BACKGROUND OF THE INVENTION

The weighing of loaded commercial vehicles, such as trucks and carts, is of great importance for the control of raw materials reception and goods and products output in companies. In the case of highways also becomes necessary, to avoid the traffic of overweight trucks on the highways.

For this demand, several scale models have been developed for static and / or dynamic weighing of vehicles, however, most of these models have the disadvantage of being partially pre-fabricated and transported to the place of installation, which is too expensive Last.

Regarding the models molded in the place where they will remain installed, two main models stand out. For example, FR 2,602,527A1 of 07.10.1986 contemplates a scale model molded at the site of use, from soil excavation, sub-base and substrate preparation, and subsequent molding of the lifting platform using jacks hydraulics. EP0108164A1 also includes a scale model molded in its own place of use, but equipped with a differentiated lifting platform system.

Such models present functionalities and point out means of elaborating scales for vehicles in the place of use, however, they present limitations.

The model described in FR 2,602,527A1, for example, does not provide easy access to the monkeys, which remain fixed in the balance. The same occurs in the balance described in EP0108164A1, which provides for the permanence of the lifting devices of the platform. Although it may seem easy to the owner of the balance, the fact that the jacks and devices do not come out can lead to a future problem if the balance is deteriorated. In this case, it would be better if the jacks were easily removed, for their better use or even for lowering the final cost of the scale.

Another drawback with respect to these models is that they contain a greater number of concreting steps, which increases the time of manufacture of the scale or raises the cost if it is necessary to use special concrete with high initial strength.

Further, such models do not allow the platform to be erected by the need for partial maintenance of the load cells and related components.

SUMMARY OF THE INVENTION

Through these and various other aspects and needs of the technical environment, and seeking to apply the experience gained in the practice of manufacturing large scale the inventor has developed the present invention by devising a platform scale for use on highways or railways which dispenses with the use of large metal structural and preformed parts for its construction.

This is made possible by the fact that the foundation and suspended platform are built with traditional building materials and labor available at the site where the scale will be installed, simply following the constructive design to obtain a platform scale that meets to the requirements and ordinances stipulated by the competent governmental organs.

Fundamentally, the present platform scale comprises:

- means for constructing a support base;

means for constructing a weighing platform;

means for stabilizing horizontal and linear movement of the weighing platform;

- means for directing and securing load cells, and;

means for interconnecting the load cells with a computerized system for storing and processing data.

As will be described hereinafter, the present patent provides for execution of the concreting in only two steps, which brings advantages over the existing models which are executed in at least three stages of concreting.

The present invention also allows to be maintained using only two monkeys, depending on the structural calculation of the platform. In addition, the design of the present scale provides for the possibility of withdrawing at least one fulcrum without the need for shoeing.

The set of components used for the manufacture of the scale in the place allows that civil work is done with the conventional methods, maintaining millimetric precision required in the project, unlike the existing models.

The invention has guiding pins which guarantee the maintenance of the alignment of the bases during the execution and guarantee the precise installation of the load cell, in addition to avoiding the slipping and misalignment of the bases during the concreting stage of the platform.

The set of edges, nonexistent in other models already existent, has three important functions, ie: it guides which is the top dimension of the slab before being assembled and which is the top dimension of the finished wall (they are attached to one another in a pre-established distance, or by screw or spacer solder, depending on the case); they have a guide that, during lifting, avoids the occurrence of accidents (it prevents the platform from falling during the lifting process of the platform); it acts as a front and rear beater to adequately absorb the impact caused by the abrupt movement of the platform during the movement of the vehicle (optionally, it may be possible to predict the existence of springs or elastomers).

Said means for structuring a support base and a weighing platform are carried out in masonry and reinforced concrete, the design of which has been designed to guarantee the rigidity and stability of the balance, in order to guarantee the occurrence of noise and oscillations below the acceptable level, so as not to compromise mass measurements when the vehicle rests on the weighing platform.

Between the longitudinal ends of the weighing platform and the support base there are provided means for stabilizing horizontal and linear movement of the weighing platform, consisting of a set of horizontal movement limiters, formed by a wall stop and a platform stop, which are fitted in front of one another, that is: the wall stop consists of a beam subsequently provided with fastening clamps in concrete and frontally of an insert formed by four "U" shaped profiled segments, fitted rectangularly between them and forming a quadrangular structure, held fixed by means of rectangular segments embedded and screwed on the edges; the platform stop is made up of five plates which are later provided with concrete clamps, which are folded at a 90 ° angle, being joined laterally and rectangularly by means of screws, forming a U-shaped structure containing a rectangular recess on its front face.

The set of horizontal movement limiters is therefore formed by the front union of the structured frames so that the wall stop insert fits within the recess of the platform stop, whereas the stop face of the wall containing the clamps for fixing to concrete facing into the weighing platform, while the face of the platform stop containing the concrete fastening clamps remains facing the support base. This arrangement is assembled during assembly of the support base molds and the weighing platform.

The present invention also provides for the use of means for directing and securing load cells comprising one or more pairs of guide bases which are engageable with each other and are provided with fixing clamps in concrete, the lower guide base being provided with pins guidewires that fit into holes in the upper guide base, both bases being spaced apart by a plastic film.

Such guiding bases are overlapped and installed at specific points during the concreting of the support base and the weighing platform so that the clamps of the upper guide base are inserted into the weighing platform while the clamps of the guide base are inserted into the support base, so that when the weighing platform is erected by the aid of hydraulic jacks, the upper guide base and the lower guide base are separated, giving room for the perfect fit of the load cell between the themselves. The attachment of the load cell to the guide bases is accomplished by means of screws, which are fixed in pre-existing holes in both the guide bases.

With regard to the means for interconnecting the load cells with a computerized data storage and processing system, the present patent provides for the existence of one or more sets of junction boxes, consisting of a fastening plate, frontally provided with fastening clamps in concrete and containing holes aligned and close to its lower perimeter while sporting the junction box on its rear face, from which flexible projections that connect to the holes of the fixing plate. This structure allows the connection of flexible conductive wires between the load cells and the respective mounting plate holes, allowing the connection between the load cell and the junction box, which has appropriate connections to connect to the computerized storage and processing system responsible for capturing the signals from the load cells and processing them.
