Description

Actuator for a train

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway carousel, and more particularly,

Conventionally, a railway train, which consists of a fixed rail and a movable point rail, each of which is placed on a treadmill to extend the rail, allows the train to travel from the main route to the conversion route and is provided with locks, wedging systems, And is controlled using an actuating device equipped with a safety system such as an electric appliance, also called " controller " in the related art.

There are two types of operating devices that are commonly used.

The first type of actuating device consists of a single actuator or motor acting on the point rail via a rod connection or a series of rods connecting the various operating positions of the point rails as shown in Figure 1, The various operating positions of the point rails are distributed starting from the front end of the point rails and a part of the rods can be single or double type and some are used to maintain the state of separation between the point rails and others are used to move the point rails.

The second type of actuation device is composed of a plurality of actuators or motors as shown in Figure 1 (B), one of which is for the so-called "master" and the other for the so-called "slave" They are simultaneously used to operate on various operating positions distributed at regular intervals.

A rod, which in any form, of any form, is connected by a rod connecting several elements together, the rod being arranged perpendicular to the orbit, is placed between two consecutive sleepers with the motor and a rod Is placed on the upper level of the sleeper. This configuration is conventional regardless of whether the motor is of the electrochemical or electrohydraulic type and whether it operates the motors one by one or in pairs as shown.

In addition, such an operating device is provided with a safety system capable of fixing the electric locomotives to their operating positions. These systems may cooperate with the motor or may be diverted with respect to the legs, such as locks known in the art by " case-bearing " locks, which are named " CC "

The positions actually occupied by the various moving parts of the stanchion are located within the motor, such as in the so-called control bar form located in the lock, or in a separate form such as a drive or mechanical drive controller known as a Paulve type controller Which is confirmed by the " controller "

Apart from locking, these safety systems and controllers are also installed between two consecutive sleepers.

After installing new substations or repairing them, a so-called "stabilization" operation is performed. In other words, it is pebbled with crushed stones of moderate size. These gravels fill the bottom of the sleepers. During the operation of filling these gravels, the rods may be covered with gravel and thus damaged by the construction of the rods described above. In order to avoid this, it is common for the rods in question to be moved before the gravel filling work is carried out. As such, it takes a lot of time to move the rods in advance, which leads to the loss of the initial control work that needs to be repeated when the rods are reassembled and thus a lot of expenses are required.

In addition to these drawbacks, there is a risk that the rods that are connected to the intended operating position are deformed when the gravel is removed.

Moreover, during operation, the rod can be interrupted, interrupted and blocked by gravel rolling into a space between two successive sleepers.

In addition to these drawbacks, there is a risk that the joints exposed to the freezing environment may become stuck with respect to maintenance of the track, and ice or frost may prevent movement of the joints and operation of the legs .

It is an object of the present invention to provide a construction for a stator that provides a configuration in which the rods of the actuating device connecting the various operating positions of the point rails can be located and protected under the upper surface of the sleeper, So that most of the drawbacks mentioned above can be solved with the aid of an improved operating device.

The subject of the present invention is an actuating device for a train, which consists of at least one specially designed sleeper and a specially designed rod. The sleepers consist of an elongated fuselage of limited width and height, the bottom is placed on the gravel, and the upper surface supports directly or indirectly the fixed rail and the point rail in particular. In particular, this sleeper is constituted by a jaw whose upper surface is formed with a limited width and depth requirement along its entire length, on both sides of which a fixing means for fixing at least the fixed rail can be placed.

The present invention will now be described in more detail with reference to the accompanying drawings.

Since the switching mechanism such as the railway track and the stator provided in the railway track is well known in the technical field, the following description will describe only those relating directly or indirectly to the present invention. For the remainder, those skilled in the art will be able to easily draw on and solve existing solutions to solve the problems encountered by those skilled in the art.

As shown, the treadle 10 of the actuating device according to the invention, made of reinforced concrete or prestressed concrete, as known, has an external standard, for example according to the standard of the sleepers.

Particularly, as shown in FIG. 3, this sleeper 10 has a bottom surface 12 on which the section has a quadrangular or trapezoidal shape and rests on the gravel, and a solen- (11) having a top surface (13) for supporting a point rail (CA) and a point rail (RA). The top surface 13 is grooved along its entire longitudinal axis to form an intermediate claim 14 having a limited width and depth. In this way, the jaws 15 are formed on both sides of the upper surface 13, that is, on both sides of the longitudinal direction 14.

These jaws can be embedded in the fuselage and are, for example, made of metal and known as a bolt or a Pandrol fastener in the railroad industry, such as a snare screw or metal fastened in a fuselage, A fixing means F of a suitable type such as an insulator made of a synthetic material into which a connector can be inserted can be installed.

According to the present invention, the width l of the request 14 is about 1/4 to 1/2 of the length L of the sleeper, and the depth p of the request 14 is about 1/4 to 1/2 of the height of the sleeper H.

This securing means can be fixed either directly or indirectly, such as flange or sol-plate or sliding bearing (C) of the rail support angle (P), as is known in the sleepers.

Thus, a request formed on the sleepers forms a housing that allows at least one rod of the actuating device to extend and move.

If desired, the request 14 may be made, for example, of a metal sheet or other material so that the jaws 15 formed on both sides of the intermediate longitudinal requirement 14 on the upper surface 13 of the sleeper are, for example, Or at least partially closed by a cover 16 which is fixed by any suitable known method,

In order to be able to install the operating device 100 using a sleeper specifically designed according to the present invention, the sleeper is slightly modified and has a rod 121 connecting the rod connection 120 and, in particular, various operating positions of the point rails, It is necessary that the constituent parts of the sleeping part 130 be arranged and protected below the height of the top surface of the sleeper.

Sufficient information on actuators and controllers can be found in Jean Alias's "La voie ferree (Railway tracks)" published by Eyrolles.

As can be seen, the typical "C-hook" of the lock consists of a "C" -shaped member 131 jointly connected to a "hook" 131 ' Shaped member 131 is a lock bolt and the through hole into which the joint connecting pin of the rod 121 is inserted is formed so as not to hinder the support angle P of the point rail RA, And are disposed in a biased manner. The latch or frame of the lock 132 is preferably resiliently and indirectly fixed to the sleepers. It is not fixed directly to the sleeper, but is fixed to the sleeper through a sol-plate if necessary. Fixed area 133 is fixed directly to the sleepers to limit the movement of the lock latches indirectly connected to the sleepers as described above in one direction. It can be seen that the walls of the stationary region that restricts the movement of the lock latches are in the form of curved, for example circular, inserts, if appropriate, of elastic buffers, for example, allowing rotational movement of the lock latches.

The actuator or actuating motor 110, for example in the form of an angular displacement horizontal arm deformed configuration or so-called rack bar configuration, is similar in cross-section to the cross section of the special sleepers of the device according to the invention and, by suitable known means Fixed to or fixed to the extension thereof. Thus, the rods extending from the output of the actuating motor 110 to actuate the point rails lie in line with the demands of the sleepers.

In the case of using, for example, a pawl type or other type of controller which allows the user to recognize the "separation" or the engagement position of the point rail, that is, the position of separation or contact with respect to the fixed rail, ) Passes through the tie rail at the lower side of the fixed rail and passes through the through hole 136 formed in the rail support angle P of the point rail RA or in the through hole formed in the other suitable type of extension provided in the web of the point rail Known in the art, which is secured to the web of the stationary rail so that it can be coupled to the stationary rail. Elastic buffers should be used so that flexible joints can be made, no matter what type of mounting structure is used. According to another connection method, the guide arm of the controller is directly coupled to the joint connecting pin of the separating rod on the point rail, and the elastic buffer is ashes on the controller arm.

At least one rod connecting the two point rails is either fixed directly to the support angle of the point rails or indirectly fixed through at least one extension of another suitable known type fixed to the web of the point rails, Lt; / RTI >

As shown, when a multi-actuator or an actuator with a motor is used, a slave motor 112, preferably a slave motor of the same type as the master motor 111, is fixed in the same way to the end of the sleeper.

According to another embodiment shown in FIG. 6, the slave motor 112 can be installed between the point rails on the axis of the trajectory. In such a case, the special sleepers of the device according to the invention are reduced in size to short sleepers with the same longitudinal requirements, i. E. Sleeper 10, referred to in the art as support sleeper or " block ". The motor is then secured to both support sleeper or block. This slave motor has two opposed outputs so that the point rails can be controlled simultaneously or specially synchronized so that one single point rail moves first and then both point rails are simultaneously and finally moved and only the other point rails To be moved. The synchronized control of these two point rails allows for considerable movement if the availability of the point rails is not compensated along the length of the point rails, taking into account the operating position along the point rails.

The movement reduction return mechanism considering the various operating positions of the point rails, that is, the position of the leading end, the middle, or the base, is arranged at both ends of the sleeper, preferably in a metal compartment, They are laid in a lid with a cover to protect them as shown in Fig.

The above description illustrates the features of the present invention, the benefits provided thereby and the benefits it provides.
