Definitions

  • the present application describes a barrier mechanism for level crossing control systems.
  • the increase in the size of the counterweights also leads to an increase in setbacks when the meteorological conditions are not favourable, particularly when there is precipitation of ice flakes and crystals, which leads to the formation of solid crystalline layers that block the regular movement of the boom.
  • CN 204 059 230 U discloses a prior art barrier mechanism comprising a compression spring set replacing the counterweight.

  • the present application describes a barrier mechanism for level crossing control systems. It is an equipment that is designed to maximize the protection in level crossings, mitigating risk behaviour and situations.
  • the static and dynamic balance of the main shaft is obtained by means of a set of mechanical elements comprised of steel cams, chains, forks, and a set of compression springs which, when compressed have the function of compensating the moment of force caused by the boom on the main shaft.
  • the mechanism is controlled by an automaton which, when it receives the information that the train is approaching, it commands the barrier to lower (obstructing the passage of road vehicles or pedestrians to the railway line), and when it receives the indication of the effective passing of the train, again commands the barrier, this time to rise, enabling once more the road and pedestrian circulation.
  • the equalizer system of the main shaft was the solution developed with the purpose of complying with the requirement of absence of conventional counterweights, which are usually used in this type of application.
  • the fact that the counterweights are not used results in a reduction of the working space of the arm of the mechanism, and this reduction mitigates the risk of material damage and harm to physical integrity, thus resulting in a system that is conducive to the well-being of all the passers-by on the road and the professionals in the area of railway signalization.
  • the function of the equalizer system of the main shaft is to balance the moment of force on the main shaft. This mechanical system compensates the torque generated by the weight of the boom when it is in the horizontal position and balances the forces that are applied to the main shaft when the boom is moving. This compensation of the force applied results in a considerably stable movement of the boom.
  • the distinctive factor of the mechanism developed resides in applying a set of compression springs, to guarantee the static balance and the dynamic stability of the boom of the barrier mechanism of a level crossing.
  • the solution developed is designed as an integral part of the level crossing system, whereby it is possible to configure lengths, types of signalling and other secondary accessories to better adapt to each scenario and type of installation.
  • the present application describes a barrier mechanism (100) for level crossing control systems.
  • the barrier mechanism (100) in one of the proposed embodiments, comprises the use of three components, the mechanism (102) itself, the boom (101) and the metallic skirt (103).
  • the main function of the barrier mechanism (100) is to protect users in circulation on the road from a situation of imminent danger whenever it is necessary to cross the railway lines.
  • the mechanism (100) is characterized by the conventional movement, wherein a boom (101) describes a circular movement of 0° (barrier in closed position - horizontal position) to 90° (barrier in open position - vertical position), there existing a boom fixation point (101) to the main shaft (1020) of the mechanism.
  • the torque and the speed provided on the main shaft (1020) of the mechanism are resulting from the transmission of the mechanical power of a DC motor (1028), and of a reduction set, comprised by a three-floor reduction, resulting in the mechanical efforts necessary to generate the boom movement.
  • this mechanism differs from the overwhelming majority of the equipment in this field of application since the balance system of the main shaft is not made in the conventional manner, resorting to the use of bulky and heavy solid counterweights on the opposite side of the road, which is a solution that is used worldwide.
  • This traditional solution due to its robustness and the volume of working space of the counterweights, can cause certain inconveniences to the passers-by and workers that are skilled in the mechanism. These constraints can result in harm to the physical integrity of a passer-by/maintenance technician and in material damages.
  • the stability of the movement is internally guaranteed, resulting in the elimination of the volume of working space of the counterweights and in the elimination of the risk deriving from the conventional solution.
  • the static and dynamic balance of the main shaft is obtained by means of a set of mechanical elements (steel cam, chains, forks, and spring pack) which have the function of compensating the moment of force caused by the boom on the main shaft.
  • the boom (101), used together with the mechanism (102), consists in two profiles that are compatible with each other: the outer profile (1011) and the inner profile (1012).
  • the outer profile (1011) is constructively designed to resist the adverse meteorological conditions and has the function of being sufficiently visible to the road users to indicate the presence of a level crossing barrier, allow the installation of light signals as well as the installation of a metallic skirt to obstruct the passage of passers-by through the lower part of the boom.
  • the outer profile (1011) of the boom (101) presents, in the lower area, a lower support rail (10111) which is destined to the fixation of accessories, namely, the metallic skirt (103) .
  • the inner profile (1012) of the boom (101) has two functions: the first one is to unite two modules of the outer boom profile (1011), so that it is possible to configure the boom (101) in several lengths, and the second function is to guarantee that, apart from the fixed length originating from each boom configuration (101), there exists the possibility of customizing and adjusting the final length of the boom (101) at the location of the installation.
  • the metallic skirt (103) acts as an accessory and it is conceived to supplement the obstruction of passage exerted by the boom preventing the road users from passing through the lower part of the boom.
  • This component is optional and the fixation thereof to the boom can be made by means of screws.
  • Main transmission system is the designation given to the set of mechanical elements of the mechanism which has the primary function in the movement of the level crossing barrier. This set is permanently demanded, whether during automatic drive, whether during the manual drive of the mechanism.
  • the movement of the mechanism is generated from the electric drive of a motor organ (1028) (CC Motor, 24V, 1500rpm, >1.2 N.m), which has the flange vertically fixed to the metallic structure that gives body to the mechanism.
  • This motor organ is responsible for creating the rotation movement (the translation movement is restricted to the three shafts and the rotation axis is perpendicular to the XZ plan) necessary for the automatic operation of the barrier mechanism (101).
  • the auxiliary motor shaft is a propelled element which has a rotation speed and rotation direction that is equal to that debited by the motor.
  • the worm screw is fixed to the auxiliary shaft of the motor, since it is necessary to transmit the movement to the shaft (10214), by means of the semi-globoid crown wheel, wheel, which is fixed to the binary limiter that is found keyed to the shaft (10214).
  • the movement transmission is transversal, irreversible, and has a 40:1 transmission relation. This transmission corresponds to a movement by direct contact by means of a gear joint.
  • the third transmission floor is the last step in the main transmission, and it guarantees that the upwards movement and the declining movement of the boom are executed, according to the swaying movement of the main shaft.
  • the equalizer system of the main shaft is the solution developed with the purpose of meeting the requirement of absence of conventional counterweights, which are commonly used in this type of application.
  • the fact that the counterweights are not used results in a reduction in the working space of the mechanism. This reduction has the main effect of mitigating the risk of material damage and damage to the physical integrity, thus resulting in a system that is conducive to the well-being of all the road passers-by and the workers in the area of railway signalling.
  • the function of the main shaft equalizer system is to balance the moment of force in the main shaft. This mechanical system compensates the torque generated by the weight of the boom when it is in the horizontal position and balances the forces applied to the main shaft when the boom is moving. This instantaneous compensation of the moment of force in the main shaft results in a considerably stable movement of the boom.
  • This equalizer system consists in a set of cylindrical compression springs with a configurable distribution, whereby the number thereof can vary between the use of 0 and 14 springs, always in even numbers and distributed in a specific manner, so that the exertion of the springs is always distributed symmetrically and uniformly in the structure that surrounds them.
  • the movement responsible for the compression of the set of springs is initiated by the DC motor and is transmitted by the main shaft to the spring pack by means of a flexible intermediary connection, using a set of four transmission chains, which are bolted to the connecting braces, which are components that are directly welded to the main shaft.
  • the connecting brace transmits the swaying movement of the main shaft to the chains by means of a dowel which operates as a mechanical joint pin.
  • This swaying movement of the connecting brace cam is converted in the translation movement in height of the sliding plate, which is the component that compresses the springs when it is subjected to the exertion of the chains in the upwards direction.
  • the movement of the sliding plate is made possible and conducted by two M20 rods, which operate with a translation joint and guarantee the lightness and uniformity of the movement.
  • the compression springs in one of the proposed embodiments, present 410mm length, 73mm outer diameter and one compresses 1mm when 18,915 N are applied in the direction of the spring shaft.
  • the movement that originates the compression of the spring set is generated in the main shaft and transmitted to the spring set by means of a semi-flexible chain of mechanical elements (connecting brace welded to the shaft, chains, forks, connecting profile and M20 rods), particularly dimensioned and designed for this application.
  • the resulting force of this compression maintains the flexible part in constant traction and allows balancing the moment of force in the main shaft.
  • the connecting braces are eccentric fixed components having a thickness that is capable of mechanically driving the microswitches.
  • the movement that is made by these eccentric components is an alternating curvilinear shuttle movement. It is an upper contact, since the contact is made by means of a line that corresponds to the intersection of the microswitch rolling head and the outer perimeter of the connecting brace.
  • the handle is installed in the horizontal shaft of the manual drive, and by means of the application of a rotation in the horizontal shaft it is possible to operate the mechanism.
  • the movement is originated by the user (maintenance technician of the railway network).
  • the engagement point is made by means of a direct transmission using cylindrical gears with straight teeth.
  • the rotation movement is transmitted from the reel (10285) to the auxiliary shaft of the motor (10284).
  • the components (10282, 10283, 10284 and 10285) have a rotation speed and torque commanded by the user. From the worm screw (10283), the sequence of movements remains the same as that of the automatic drive.
