Definitions

  • the invention relates to a railway ballast conveying device, particularly for the evacuation of used ballast.
  • convoys are usually used for specific tasks, each convoy being generally planned and specialized for a particular task.
  • ballast evacuation train When replacing the used ballast with a new ballast, it is planned to evacuate the used ballast using a specialized convoy called by specialists "ballast evacuation train".
  • a ballast evacuation train generally comprises a plurality of used and used ballast transport cars preceded by a loading car.
  • the order of filling of the reception and transport wagons of used ballast is carried out by filling first of all the last wagon of convoy, then the penultimate wagon of the convoy, and so on until the first wagon of the convoy .
  • Each ballast receiving and transport car is equipped with a conveyor belt that cooperates with the conveyor belts of the adjacent cars, to ensure continuous transport of the ballast to a desired location or car.
  • each conveyor belt cooperates with at least one ballast ejection means in the wagon.
  • Ballast ejection means in the receiving and transport wagon are generally referred to as "plow" by specialists and railways.
  • each used ballast transport receiving wagon is equipped with four ejection means or “plows” with fixed position.
  • Each ejection means or plow must be manually activated by an operator to progressively fill each wagon uniformly, starting from the tail of the wagon to fill the car to the head of the car.
  • the plows currently used are in the form of a fixed obstacle whose vertical descent can be controlled by an operator acting on a control handle and a control pedal to be activated simultaneously.
  • each plow or ballast ejection device deflects the ballast flowing on the conveyor belt to eject it into the wagon under the conveyor belt.
  • each ejection plow In the raised state, or passive state, each ejection plow is maintained at a predetermined height above the ballast conveyed by the conveyor belt, so that this ballast circulates freely towards the rear of the wagon of the convoy.
  • each ballast ejection means or plow the operator must move to the corresponding location to perform physical efforts corresponding to the lowering or elevation of the plow.
  • the operator must perform twenty-four times significant physical efforts corresponding to the lowering and when the car is partially filled at the place of operation.
  • the ejection means or plow are fixed permanently with respect to the conveyor belt and the transport receiving wagon prevents a uniform and continuous distribution of the level of ballast in the transport receiving wagons: indeed , the fixed locations of each plow corresponds to raised heaps of ballast, while the intermediate zones will be less filled with used ballast than the zones corresponding to the ejection of the ballast by the corresponding means.
  • the current ballast ejection system used in the reception and transport wagons poses a filling problem when the convoy is traveling on inclined curves.
  • the carriage of the used ballast and its ejection in the wagon is not effected in a uniform manner.
  • the ballast is poured into the car unequally and inwardly of the curve or the turn, so that the level of used ballast in the car is not horizontal but inclined. This results in insufficient and unequal filling which reduces the productivity of the evacuation of used ballast.
  • a first object of the invention is to overcome the disadvantages of the known state of the art, by proposing a new ergonomic device and easy to implement to ensure the evacuation of the used ballast.
  • a second object of the invention is to provide a new ballast conveying device ensuring a uniform filling of used ballast transport receiving wagons.
  • a third object of the invention is to ensure uniformity of loading of used ballast transport wagon, even in continuous curve or inclined turn.
  • the subject of the invention is a device for conveying railway ballast, in particular for the evacuation of used ballast, of the type comprising at least one ballast transport wagon equipped with a conveyor belt cooperating with a means of ejection of the ballast.
  • ballast in the wagon characterized in that the ballast ejection means is a means movable along at least a portion of the conveyor belt and operable between an open position corresponding to the passage of the ballast on the conveyor belt and a closed position corresponding to the ejection of the ballast of the conveyor belt in the wagon.
  • the used ballast transport car 1 comprises a conveyor belt 2 surmounted by a means 3 for ejecting used ballast conveyed by the conveyor belt 2 into the interior of the wagon 1.
  • the conveyor belt 2 extends from the front end of the car 1 and protrudes from the rear end of the car 2 to possibly dump used ballast on a next conveyor belt mounted on the next car of the convoy.
  • a used ballast ejection means 3 comprises a frame 3a carrying two lateral deflectors 3b mounted on a carriage movable along the conveyor belt 2.
  • the circulation of the carriage of the device 3 is limited by two end frames 4 and 5 forming a stop integral with the frame of the conveyor belt 2.
  • the frame 3a carries one end 3c for mounting two electrohydraulic cylinders 6 and 7 for actuating doors 8 and 9 between an open position ( figure 2 ) corresponding to the free passage of used ballast and a closed position ( figure 3 ) corresponding to the deflection of the used ballast to the deflectors 3b and the fall of the used ballast in the wagon 1.
  • linear actuators 6 and 7 can be chosen from all known linear actuators, without departing from the scope of the invention.
  • the displaceable ejection means 3 replaces the four fixed ejection means of the prior art provided on the conveyor belts of the prior art and avoids significant efforts to the operator of the convoy.
  • the displacement of the "moving plow" or ejection means 3 can be performed by a gear and chain mechanism actuated by a geared motor controllable by means of a housing held by the operator.
  • the ejection means 3 can be stopped at any desired location between the stops 4 and 5 of the conveyor belt 2, which improves the filling of the carriage 1 receiving transport.
  • the even distribution of the used ballast in the filled car 1 also makes it possible to increase the discharge efficiency of the used ballast, because of the increase in the filling rate of each wagon of the convoy.
  • the operator-controlled displacement control box also preferably carries the controls of the electro-hydraulic cylinders 6 and 7, so as to optimize the filling of the wagon.
  • the frame 2a of the conveyor belt is mounted on a cradle 2b attached to the wagon 1 not shown in detail.
  • the cradle 2b attached to the wagon 1 has an arcuate conformation adapted to allow the rolling of two rollers 2c on which the frame 2a of the conveyor belt.
  • Stops 2d are provided on either side of the rolling track of the cradle 2b.
  • the cradle 2b In the horizontal circulation position of the figure 4 , the cradle 2b is horizontal and the frame 2a which rests on it by means of the rollers 2c is also horizontal, so that the conveyor belt 2 is horizontal and transports the used ballast over its entire useful width.
  • the cradle 2b secured to the car 1 is also inclined, while the conveyor belt 2 is disposed horizontally, thanks to the rolling of the rollers 2c on the track of the cradle 2b.
  • the conveyor belt 2 conveys the used ballast uniformly, over its entire effective width and horizontally, even on a slope or in a bend.
  • a preferred embodiment of the invention comprises a linear actuator 10 attached to the frame of the conveyor belt 2 on the one hand and secured to the car 1 on the other hand.
  • the linear actuator 10 is preferably an electric actuator operating at all times and acting as the attitude control of the conveyor belt: thus for each convoy car entering a curve having a predetermined superelevation, the conveyor belt 2 fixed on the car is rolled rollers 2c on the raceway of the cradle 2b of the opposite angle, so that the conveyor belt 2 is horizontal.
  • This cant correction can be performed automatically, with a lateral inclination sensor of each wagon of the convoy, to deliver a control signal to the linear actuator 10 tilt correction.
