Description

"INVERTED CLIP FIXING AND LOCKING SYSTEM AND INVERTED CLIP".

The present disclosure is intended for the purpose of presenting an inverted rail clamp fastening and locking system and respective inverted clamp, related to the field of application of the railway sector itself.

The above system and inverted clamp have been designed, designed and developed to offer a new method of applying, securing and locking rail clamps, providing a number of benefits and advantages over those conventionally used.

It is well known, and most notably to those skilled in the art, the existence of a wide variety of rail fastening models, developed in various types of formats, but each with specific applications. One of the major concerns of technical experts, companies and users of the sector, as well as the indispensable effectiveness in the structural fixation of the railway network, lies in the need to provide means to make the action of vandals and unscrupulous people who seek to subtract rail clips as much as possible either by acts of savagery or to illegally benefit from the resale thereof for scrap metal or similar establishments because of the commercial value of the raw material in which they are manufactured.

The state of the art reveals, for example, the development of special shaped staples which, when incorporated into support plates (wooden sleepers) and concrete anchor bolts (concrete sleepers), reduce the action of melistas on purpose relatively. from damaging and / or misappropriating them. However, and despite all the efforts of subject matter experts to develop means and products in an attempt to prevent this damnable practice, depredations and thefts of such material continue to be reported, including simply by using tools or mallets larger than 02 Kg. .

Another problem with existing conventional staples hangs on the gauge of the material in which they are manufactured to achieve the degree of longitudinal retention (loads in general) whose required retention threshold is not always effectively achieved, as well as becoming less flexible and relatively heavier, notably because they employ a larger amount of raw material in their respective conformation. Yet another drawback observed in conventional clamps hangs in the form of fixing them, in an already traditional positioning, known as elastic fixation and which, despite everything, does not completely prevent theft and vandalism.

Taking into account only some of the above deficiencies, and in order to overcome them, the inventor, a branch person, has devised, designed, and developed the present reversed rail clamp and locking system and its inverted clamp. , starting with the radical change in the way it is inserted in the elements that make up the set of points of the rail track.

In its new conception, the specific model of

The rail clamp is incorporated into the fasteners in a fully inverted manner, also providing strategically located cutouts and bevels which, according to tests performed, in combination with the developed fastening form, prevent their withdrawal, creating a true locking point between the end. clamp and the contact area with the anchor / jamb, so that the greater the force applied in attempting to improperly withdraw the clamp, the greater its direction and lower pressure against the anchor, further increasing the strength of the assembly.

In addition, while conventional staples are usually manufactured in standard gauges, the model presented here can be obtained in a relatively smaller thickness, resulting in and proven to provide better longitudinal and rail retention, adding the benefits of becoming lighter. and to spend less raw material, also reducing the costs involved. At the same time, its smaller thickness gives it greater flexibility, while minimizing the risk of breakage, even with greater resistance to loads established by 15 national and international standards. The inverted configuration gives the newly designed inverted clamp the physical effect of semi-rigid attachment at the deflection point of the rail skate attachment, thereby increasing its retention anchorage and can be made into a smaller, consequently lighter gauge, yet yielding results 20 better in the technical behavior of the inverted fastening system applied to different types of rail skids.

Thus, the clamp in question appears as a natural anti-vandal, since the inversion in the locking system eliminates the lowering for the said anti-vandal effect observed in the 25 conventional models, since its configurations usually subject the bolt projection to wear. mainly from the second or third removal of the clamp, given that the anchor bolt most of the time when talking about concrete sleepers, now more evident in large-scale rail projects, and consequently of lower hardness, remembering that in traditional systems the anti-vandal concept makes it difficult but not completely prevent the removal and / or theft of the clamp.

Another major advantage of the rail clamping system and its inverted clamp in question is that it can be applied to the same elements that comprise the rail locking set [anchor bolts, sleepers, support plates, etc.), enabling its use and use even in already approved sections and / or permanent track assembly, eliminating changes in base designs or modifications in the initial structural calculations, saving costs and immeasurable time in the planning and implementation of rail networks, or that is, the new fixture created can be applied to concrete sleepers (jambs) wooden sleepers (support plates) and steel sleepers (welded plate jambs) without the need for modification / adaptation of these components, mainly for application, since The system is a natural anti-vandal, favoring and protecting the permanent way.

Still another advantage offered in the system and product presented here, notably in relation to the conventional ones, 20 is the versatility of application in differentiated rail versions (example - “TR” rail - slightly inclined rail foot, “UIC-60 rail”). parallel rail in the fastening part), the new clamp can replace and fit both or more types of rails without the need for adjustments or modifications, ending in 25 with a universal “TR” and “UIC” rail clamp where the tests applied to them, regarding the current standards, were fully met.

In this same respect, the inverted rail clamping and locking system and related inverted clamp in question can be considered as a semi-rigid clamping material, differing from the common clamping formats, known as elastic clamping, in that are applied in the permanent way.

In view of the foregoing and with a view to a better understanding of the subject matter of the patent application disclosed herein, illustrative but non-restrictive drawings are presented, accompanied by numerical references, identified and explained along with the following description, where:

It should be noted that the cushioning insole (8) can be applied on top of the wooden sleeper support plate and, more rarely, on steel sleeper.

In the light of all the foregoing and properly illustrated, it is understood that the present application deals with an innovative inverted rail clamp fastening and locking system and its inverted clamp, adding a number of advantages inherent to its applicability, involving novelty. and inventive activity, in addition to the susceptibility of industrial application, being deserved of protection as patent pending, which is now claimed.
