Definitions

  • the present invention relates to a railroad car for the transport of overburden, according to the preamble of claim 1.
  • railway wagons usually consist of two different parts: the first forms the organs for the movement of the wagon, d.s. the multitude of pairs of wheels running on rails; the second, on the other hand, consists of a "box" with high side walls that is open at the top and sits on a lower frame.
  • This box forms the container for the overburden that is poured in from above by the excavator machines.
  • a train in the working zone consisting of a series of such wagons which, after loading of the overburden has been loaded, are driven into an area that has been specially prepared for unloading the overburden.
  • the railroad cars are usually provided with a series of telescopic arms, each operated by pneumatic pistons inserted between the lower frame and the "box".
  • the operator actuates the pistons mentioned, which enable the box to be tilted to one side, so that the waste material can be emptied on one side thereof and deposited on the underlying floor.
  • the object of the present invention is therefore to avoid the above-mentioned inadequacies by creating a railroad car for the transport of overburden, which is cheap and is provided with a combination of elements in its interior, which also rationally, quickly and conveniently load / unload the overburden allow previously unprepared soil.
  • One of the advantages achieved with the present invention consists in the provision of a series of conveyor belts which ensure the rapid and efficient transport of the overburden brought into the box;
  • the second movable and rotatable conveyor belt enables the overburden to be unloaded outside the railroad car, so that preparatory work with scraping buckets can be omitted.
  • the railway car in question consists of a double pair of wheels 1, which can be moved on rails 21 and are connected by a horizontal flat bottom 2, on which an open-top box 3 is seated, which serves to receive the overburden, which in its entirety also includes 4 is designated.
  • the box for receiving the overburden 4 is defined by a fixed structure consisting of the walls 3, a plurality of lids 7 to be opened and a closure bottom formed by the horizontal emptying belt 9.
  • the conveyor belt 5 is arranged centrally and in the longitudinal direction on top of the box 3 and has an extension which is greater than the total length of the box.
  • FIG. 1 shows that the two ends of the conveyor belt 5, each running around drums 5t, partially protrude from the box 3.
  • a wedge-shaped element 6 Arranged above this conveyor belt 5 is a wedge-shaped element 6, which serves to displace the overburden 6 passing on the conveyor belt 5 and is horizontally movable over the entire longitudinal extent of the box 3 by means of slide devices 11.
  • This wedge-shaped element 6 consists of a pair of opposing blades 6a and 6b, which form a wedge in plan.
  • Said slide devices 11 consist of a pair of arms 11a and 11b (see FIG. 2) which form a frame which comprises the wedge-shaped element 6 on two sides and which are attached at one end to the articulated parallelogram 13 and, moreover, with small wheels at the other end 14a and 14b are provided, which on a pair of horizontal rails 15 run, which form part of the support frame of the conveyor belt 5 or alternatively can be provided at the upper end of the box 3 and which are arranged on opposite sides to the conveyor belt 5 and extend over the entire length of the box 3.
  • the plurality of lids 7 are arranged in pairs opposite to each other and together with the end part of the box 3 form a corresponding row of funnel-shaped module units for receiving the overburden 4.
  • These covers 7 can be moved by means of corresponding movement devices 12 between an extreme closed position of the module unit, in which each cover 7 is in contact with the end part of the box 3 without dissolving the continuity, and an open position of the module unit, in which each cover 7 is in one from the end part of the box 3 is located and consequently allows the inflow of overburden 4 over said end part of the box 3 also.
  • the movement devices 12 consist of a hydraulic piston 16 for each of the existing covers 7, the ends of which are articulated on the inner part of the flat bottom 2 or on the cover 7.
  • This emptying belt 9 can be pivoted about its own axis by means of movement devices 10 ⁇ which consist of a motor-driven turntable 17 which moves the aforementioned end (visible in FIG. 2) by an arc of approximately 180 ⁇ °.
  • the turntable 17 swivels the discharge belt 9 between an inoperative position, in which the emptying belt 9 is arranged parallel to the flat bottom 2, and an unloading operating position for the waste material 4, in which the emptying belt 9 is arranged transversely and projecting to the flat bottom 2.
  • the discharge belt 9 is protected by a trough frame 18 which completely encloses it, except, of course, the end of the discharge belt 9, which is intended for unloading the waste material 4 onto the underlying floor.
  • the aforementioned devices for the movement 30 ⁇ and positioning 31 are - as can be seen well from FIGS. 1 and 2 - arranged below the box 3 and parallel to it over its entire length, in order gradually to act as the pivot point of the discharge belt 9 in the end Bring the area of the upper lid 7 located in the extreme open position.
  • these devices for the movement 30 ⁇ and positioning 31 consist of a support carriage 32 for the emptying belt 9, which is inserted between the flat bottom 2 and the end of the emptying belt 9 which acts as a fulcrum and has on both sides a number of small wheels 33, which are in a pair run from mutually parallel guides 34 which are fastened on the flat floor 2 and extend over the entire length of the railroad car.
  • the support carriage 32 is connected on both sides to an endless chain 35 which, for example, runs around sprockets (not shown here), which are provided at the relevant ends of the railway carriage, and is driven by means of a reduction gear 40 ⁇ which is arranged on the support carriage 32 to allow the displacement and positioning of the emptying belt 9 in the area of the cover 7, little by little as they open.
  • the support carriage 32 can moreover be provided with path end devices which enable the support carriage to be stopped exactly in the region of the upper cover 7, which is in the extreme open position.
  • the railway wagon designed in this way works in the following manner, assuming that a set of several railway wagons stands for loading the overburden in the loading zone: the machines provided for loading the overburden put it on the conveyor belt 5 of the first wagon and it is transported along the same.
  • the wedge-shaped element 6 is arranged in a raised position by means of the articulated parallelogram 13, so that the waste material 4 can pass through to the last car.
  • the wedge-shaped element 6 is in the position approximated to the conveyor belt 5 and in the region of the closing end of the box 3, in order in this way to cause the waste material 4 to fall down into the funnel-shaped module unit located underneath.
  • the wedge-shaped element 6 is pushed forward in the direction C opposite to the direction of movement of the conveyor belt 5 (see arrows in FIG. 1), so that the inflow of waste material 4 into this last module unit is interrupted and with the filling in relation to the direction of movement of the overburden 4 in front of the module unit is started.
  • the wedge-shaped element 6 of the following car is actuated, which begins with the filling phase of its module units as described above.
  • the emptying belt 9 is pivoted by approximately 90 ° for each wagon, so that it is arranged on the side of the railway line on which the waste material 4 is intended to be unloaded.
  • the various lids 7 are then opened in individual succession by means of the pistons 13, which allow the waste material 4 to be fed directly onto the emptying belt 9, from which it is then transported to the intended unloading point.
  • the emptying belt 9 is brought under the next module by means of the support carriage 32, which in turn is moved by the chain (s) operated by a worker, in order to be able to empty the waste material 4 therefrom.
