DRIVING NEEDLE AND DRIVING HAND DEVICE FOR RAILWAY ROADS

DESCRIPTION

TECHNICAL FIELD OF THE INVENTION

The present invention is encompassed in the field of the railway sector, specifically, it has its application in the safety mechanisms at railway deviations, even at high speed.

The invention is a device for actuating and locking the needles of railroad diversions, which, thanks to its novel structural configuration, can be arranged at the center of the railway track and without the need to drill the counter-needles for fixing to the same.

BACKGROUND OF THE INVENTION

The deviations are track devices used in the railway lines, which make it possible to pass the rolling stock or train from a direct track to a deviated track, or allow it to continue on the direct track. The detours are formed by three different parts: change, junction and crossing lanes.

Specifically, it is the change that directs the meaning of the traffic, either by the direct route or by the diverted route. Usually, they have needles or mobile sprats that make the train on track in the desired direction (direct or deviated).

To do this, the change is provided with electric drive means, which, start the drive mechanism that couples one of the needles to the corresponding counter-needle of the way and separate the other needle from its counter-needle corresponding guaranteeing minimum passage between the passages, in such a way that it allows the train to be routed to the desired direction in safe conditions.

Even when the electric drive means can comprise their own

internal locking means, the change usually has a mechanism associated with

external mechanical safety to said electric drive means (external enclosure).

The mechanism of external bolt increases the level of safety in the circulation by the railway deviation, therefore, eliminates the risk of breakage of the bars that actuate the needles, by keeping said needles mechanically locked in the position in which the deviation was checked.

The drive and locking devices for railroad diversion needles known to the inventor have the disadvantage that they require drilling or drilling the core of the counter-needles for installation in the diversion, which implies that the railroad loses its warranty from the manufacturer of it. An example of these known devices is that shown in patent document ES 2037879, which requires that the bolt case of its bolt mechanism be connected with a flange that is screwed to the outer face of the counter-needle, forming a single construction piece that surrounds the base of the rail of said counter-needle.

For this reason, it is necessary to design, in a simple and economical way, a device for driving and locking the needles for deviations of railway lines that overcome the aforementioned inconvenience.

DESCRIPTION OF THE INVENTION

The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.

The object of the invention is a device for actuating and locking the needles of railway deviations. The technical problem to be solved is how to avoid the need to drill the counter-needles of the deflection to carry out the installation of the device, and thus, not to lose the manufacturer's guarantee.

The device of the present invention comprises a drive mechanism and a bolt mechanism. The drive mechanism is adapted to move,

perpendicular to the longitudinal direction of the track, some needles of the deflection

between a first position and a second position. For its part, the bolt mechanism is adapted to block the needles in the first or second position.

Additionally, the drive mechanism comprises a push rod with thrust recesses formed at each end of the bar, and the bolt mechanism, comprises connecting rods with connecting rod tails adapted to engage alternately in the recesses of the ends of the drive bar, and thus, transmit movement from the drive bar to the needles of the deflection.

Likewise, each connecting rod and the corresponding end of the driving bar are arranged through individual bolt boxes of the bolt mechanism, where each of said bolt boxes is adapted to block the connecting rod tail in the corresponding recess when the needles reach The first or second position.

On the other hand, the needles are joined together by means of two tie rods, which are coupled to a central support block, and pivot ends of the connecting rods are coupled to the central support block below the union braces. , so that the connecting rods and the driving bar are arranged in the same lower plane parallel to the plane of the railway.

As can be understood, thanks to the novel structural configuration of the drive device and bolt of the needles of the deflection, it can easily be arranged at the center of the railway track, for example, between two sleepers of said track. Thus, it is possible to provide a solution to the technical problem posed, that is, when the device can be placed in the center of the track, the need to drill or drill the counter-needles for its installation to the diversion is eliminated, and with that, said counter- needles do not lose the manufacturer's warranty.

Likewise, the horizontal layout, that is to say, in a lower plane parallel to the plane of the track, of the main elements that make up the mechanism of actuation and lock of the device, that is, the connecting rods and the driving bar with their recesses, facilitates the assembly and maintenance of these elements,

while avoiding the accumulation of land or other types of dirt in the

recesses, which could prevent or imply an inadequate operation of said drive and lock mechanisms.
