Definitions

  • the present invention relates to a machine for the renewal of railways comprising a plow, of the type applied in machines for the renewal of railways, for breaking up the pre-existing compact ballast, after the removal of old rails and sleepers, and preparing the route for laying new sleepers.
  • Plows used for this purpose are already known which act by simple insertion into the ballast, caused by the advancement of the machine to which the plow is applied, and which meet a very high resistance to advancement, on the one hand because that the gravel from the old ballast is very compact due to the compaction exerted by the convoys in transit and the sticking caused by sludge, metallic dust and other substances depositing on the rock, and on the other hand also because the slow forward speed of the machine does not favor the establishment of a regular flow of rubble displaced by the plow. It follows the impossibility of digging with these plows a furrow of great depth.
  • the laying level of new sleepers must be lower than that of previous sleepers, because of the adoption of higher sleepers and / or rails, and the need to maintain the plane of the rail at same level as before, because we are bound by the height of the overhead line, by the size of tunnels, level crossings, etc.
  • the object of the present invention is to increase the efficiency of a machine of the type mentioned, so as to be able to dig with it, without difficulty, a groove of depth such that it can accommodate the new sleepers, without requiring no subsequent intervention to lower the level, even if higher sleepers or heavier rails are installed than those previously installed.
  • the plow is equipped in the area of its plowshares, with members for disintegrating and / or pushing back the ballast, these members being mounted movably on the chassis of the plow and being driven by an actuating mechanism according to a periodic movement, having a component perpendicular to the plowshares and such that the end of these members directed towards the outside makes, in external working positions, protrusion with respect to said plowshares.
  • the members consist of ejectors acting like a piston, passing through windows made in the lower zone of the plowshares, these ejectors moving transversely to the direction of movement of the plow under the action of the actuating mechanism which gives them reciprocating movement between internal positions, in which they do not protrude from the lower part of the plowshares and external positions in which they protrude relative to said plowshares.
  • each ejector during its displacement from the internal position to the external position, positively pushes a mass of stone from the ballast to one side, disintegrating and displacing it, without its energy resulting from the advancement of the plow and therefore by exerting a force which can be conveniently preset during the study and adjustment of the actuation mechanism.
  • the ejector In the next phase in which the ejector has returned, it does not oppose the advance of the plow. Any mass of rubble displaced by an ejector is then taken up by the following ejector, which by the di Vergence of the plow blades acts on a greater width, and this until the gravel is overturned on the sides of the trench made by the plow for the laying of new sleepers.
  • the plow can dig a furrow of much greater depth than that achievable without ejectors, and the extraction depth can thus be chosen so that it then does not require any subsequent lowering of the installed sleepers.
  • the actuation mechanism is preferably provided so that, while a certain number of ejectors are moved to one side, a corresponding number of other ejectors are moved to the opposite side, thereby achieving at least approximate balancing of the lateral forces.
  • the deeper excavation, necessary in the center of the trench to unload the central areas of the sleepers, can be carried out by a point portion, of greater depth, of the plow blades, as usual, or by a horizontal milling machine that can be rolled in either direction depending on whether you want to unload the largest amount of rock from one or the other side of the dug trench.
  • the members consist of two blades, preferably toothed on their outer face, arranged below the coulters and at least approximately parallel to them and that the actuation mechanism is designed for the animate a movement which is approximately a translation along a closed trajectory.
  • ballast is perfectly broken up by means of these blades which, by their movement of translation in closed loop, combined with the movement of advance of the machine, act like a kind of grinding wheel.
  • the ejectors and the blades can be combined on the same plow.
  • FIGS. 1 to 6 illustrate the first embodiment of the plow.
  • the reference 1 indicates a longitudinal span of the chassis of a machine for the renewal of railway tracks, of the type known per se, to which is applied, in this example, the plow according to the invention.
  • the reference 2 indicates a toothed wheel of this machine which, by cooperating with guides 3, serves to remove from the old ballast 4 the old crossbars: 5, leaving empty cavities in place 6.
  • the machine also has a device for laying new sleepers 7; from it are visible lateral metal plates 8 intended to prevent, during the laying of the new sleepers, the collapse of the rock piles formed laterally by the plow, These piles then slide partially behind the ends of the plates 8, immobilizing in their positior the new 7 sleepers posed.
  • the plow is sispandue to the structure 1 by means of supports 9. All these parts, indicated in phantom, are known. The level of the largest digging depth achievable with a known type plow, subject to the limitations set out at the beginning, is also indicated in dashed lines by line 10.
  • the two plowshares forming an angle between them to constitute the plow according to the invention. They are supported in a known manner by a chassis 12, suspended from the supports 9.
  • the chassis 12 also carries, laterally, plates 13 which extend on a part, parallel to the direction of advance A of the plow, the rear ends of the plowshares 11 to support the lateral piles of stones which, after having been abandoned by the plates 13, will still be temporarily supported by the side plates 8 mentioned above.
  • the plowshares 11 constituting the plow have, as usual, a concave profile, the upper part of which, turned towards the outside, in the manner of a mouldboard, pushes the piles of stones formed by the plow.
  • windows 14, square in the example cited, which in this example are at number of four per share are made windows 14, square in the example cited, which in this example are at number of four per share.
  • the pair of windows 14 closest to the V-shaped top of the plow is occupied by two ejectors, or pistons, 16 moving transversely between guides 17 and connected together by a rod 18 so that the two ejectors 16 (formed as two pistons of almost square section) can move integrally in transverse direction along arrow T.
  • the second pair of windows 14 is occupied by a pair of ejector 19 also connected together by a rod 20 and guided to move in the transverse direction T.
  • the third and fourth pair of windows 14 are in turn occupied by a third and fourth pair of ejectors, respectively 21 and 23, connected together by rods, respectively 22 and 24.
  • the rods 18 and 20 are coupled by a pendulum lever 25, with uneven arms, articulated to the fixed frame of the plow and provided with a lever arm 26.
  • the rods 22 and 24 are coupled by a lever balance 27, with unequal arms, articulated to the fixed frame of the plow and provided with a lever arm 28.
  • the arms of the lever 26 and 28 are connected by a connecting rod 29 to which is fixed a hydraulic cylinder 30 whose opposite end bears against the chassis 12.
  • the connecting rod 29 is given an alternating movement which, by means of the lever arms 26 and 28, results in an alternating oscillation of the balance levers 25, 27 and in an alternative translational movement in the transverse direction of the various ejectors 16, 19, 21 and 23, so that while two of them move on one side, the other two move on the opposite side. Furthermore, the difference between the various lever arms results in an increasing amplitude of the displacement from the ejector 16 towards the ejector 23.
  • the arrangement of the ejectors attached to the pairs of rods makes it possible to simplify the construction and the actuation means, while the actuation in the alternately opposite direction of the following ejectors ensures the balancing of at least most of the lateral forces.
  • the force exerted by the hydraulic cylinder 30 discharges on the chassis 12, but according to a variant not shown, particularly useful when it is desired to release the chassis from such a load, the hydraulic cylinder can be inserted in place of the connecting rod 29, thus producing oscillations in the opposite direction of the balance levers 25 and 27 and acting on the chassis only at the pivot points of said balance levers.
  • the greater efficiency of the plow according to the invention makes it possible to execute with it the digging of the trench in full depth, at a level illustrated by line 31, so as to deposit the new sleepers 7 there, even if they are of greater thickness, without the need to dig several times under them, while with a traditional plow digging could only be pushed to a level such as that indicated by line 10, to Comparative title, in Figure 2, making it necessary successive interventions of an appropriate excavator equipment.
  • small trenches like that indicated in dotted lines at 33 in FIG. 4 are dug laterally to the line, to receive a part of the stone broken up by the plow, while the excess forms piles 34 momentarily supported by the metal plates 13 and then by the plates 8; after the passage of these, as shown in FIG. 4, on the right, the pile 34 partially collapses, forming an inclined embankment 35 which envelops the ends of the new sleepers 7 laid, immobilizing them in their position.
  • the piles 34 are formed below the level of the new rails 37, which are lifted temporarily by the machine in a known manner, on the edges of the dug trench and above which the old rails 36 to be removed are placed, as illustrated in FIG. 4.
  • the central zone of the trench for laying the crosspieces 7 must be lowered to level 32 located below the laying level 31, to release the central part of the crosspieces from the bearing load.
  • This can be obtained, as usual, by providing the plowshares 11 of the plow with a front part 11a extending at level 32.
  • the same effect can also be obtained, according to the invention, by mounting under the end front of the ploughshare 11 a horizontal milling machine 38 (fig. 5 and 6) rotated by an electric or hydraulic motor.
  • the shape, number and position of the ejectors may vary, as well as the nature and arrangement of their actuating means. These can include kinematics relating to a single energy source, as in the example described, or else several energy sources connected directly or indirectly to the ejectors can be used. Hydraulic cylinders can advantageously be used as a source of energy due to the presence of a hydraulic installation on board the machines for the renewal of railways, however mechanical or electromechanical sources of energy can also be used. The ejectors which correspond on the two sides of the plow could also be actuated in opposite directions instead of being joined by a rod.
  • FIG. 7 to 9 illustrate a second embodiment of the plow according to the invention.
  • the ejectors or pistons are replaced by two blades 42, located below the two plowshares 41, at least approximately parallel to them, and which are driven by means of an appropriate mechanism, of a movement which is approximately a translation along a closed trajectory.
  • the mechanism has been designed such that each blade 42 is given a circular movement at the front and an elliptical movement at the rear, as will be explained below.
  • the two plowshares 41 which form an angle between them are fixed to the chassis 40 of the plow which has lateral supports 40a.
  • On this chassis 40 are also mounted, in a movable manner, two blades 42 which are further connected to each other at the front by means of teeth 52 and a nose 43 articulated at their anterior end.
  • Each blade 42 is connected to its front part by a connecting rod bearing 56 to an eccentric piece 44b which is located at the bottom of an eccentric shaft 44 (fig.8); the rear part of the blade 42 is articulated by a pin 61 on a connecting rod 45 itself articulated by a pin 60 to a connecting rod 46.
  • This connecting rod 46 is equipped at its front part with a fork 47, shown diagrammatically in fig.
  • the two blades 42 are articulated at their anterior end, by means of two rounded teeth 52, to the nose 43 which constitutes the most forward part of the plow, the lower edge of the nose 43 and of the teeth 52 being moreover below the level of the blades 42 in order to dig a deeper central groove, as explained in relation to the first embodiment.
  • the eccentric shaft 44 prints on the one hand to the blade 42, by means of its lower eccentric 44b, a circular movement whose radius corresponds to the eccentricity of the eccentric, and which is represented by the arrow F1, and on the other hand to the connecting rod 46, via the fork 47, a movement oscillating about the axis 48, represented by the arrow F2.
  • the oscillating movement of the other end of this connecting rod 46 therefore of the pivot axis 60 on which the connecting rod 45 is articulated, performs an oscillation whose amplitude depends on the ratio of the lever arms of the connecting rod 46 and the value of the eccentricity of the eccentric 44a.
  • the amplitude of this oscillation can therefore be amplified by an adequate ratio of the lever arms of the connecting rod 46.
  • the end of the connecting rod 45 and therefore the rear end of the blade 42 on which it is articulated by the axis 61 are therefore forced to describe a movement along an elliptical trajectory, illustrated by the arrow F3 (fig. 7) which results from the circular movement of the front part of the blade 42 and from the oscillation of the connecting rod 46, the major axis of this elliptical path F3 being found to be approximately perpendicular to the blade 42.
  • the mentioned movements of the front and rear part of the blade 42 are therefore synchronized by the connecting rod 46.
  • the ratio of the lever arms of the connecting rod 46 and the eccentricities of the eccentrics 44a and 44b will be chosen so that there is an amplification of the movement to the part posterior of the blade relative to the movement of its anterior part, so that the major axis of the ellipse described is greater than the radius of the circular path of the anterior part of the blade 42.
  • This movement can be modified at any time as a function of the value of the eccentricities of 44a and 44b, of the eccentric ratios of the shaft 44 and of the ratio of the lever arms of the connecting rod 46.
  • the arrangement of the elements is preferably such that the movement is asymmetrical, that is to say that when a blade 42 projects laterally from the lower part of the ploughshare 41, the other blade retracts. Because the nose 43 of the plow is articulated to the two blades 42 via the two end teeth 52, the asymmetrical movement of the two blades gives the nose 43 an oscillating movement intended to facilitate penetration into the ballast.
  • a motor is used for driving the pinion 49 having a rotational speed of 100 to 300 revolutions per minute and the ratios of the eccentrics and of the arms are such that the amplitude of the movement at the anterior part of the blade is about 3 cm while that of the posterior part is about 6 cm.
  • this system of blades 42 is superimposed, the system with lateral ejectors 53, or pistons, as described above, which makes it possible to expel the ballast accumulated by the advance of the plow.
  • a combined plow is thus obtained which combines the advantages of the two plows described above.
  • a vibrator 54 fixed to the frame of the plow as well as a rectilinear sheet 55 which extends the plowshares 41 and which temporarily retains the rubble accumulated on the edges.
