Definitions

  • the ramming machines for railway lines very often comprise removable tools which can be mounted on a certain number of vibrating tool-carriers, having the shape of arms, which are arranged'in pairs opposite to one another on either side of the sleeper which is to be rammed and which are generally arranged on one or more supporting members, called mobile frames be cause they can be displaced in relation to the fixed frame of the vehicle in order that the tools may be sunk into the ballast.
  • the two arms of each pair are articulated on an auxiliary supporting member which is made to vibrate by means of a generator of vibrations of any type and is then secured to the mobile frame proper, i.e., to the frame which is adjustable in height as we have seen above, preferably by means of damping members in order to reduce the vibrating masses to a minimum, which ofiers all the evident advantages of such an arrangement.
  • the present invention aims at remedying these defects of the hydraulic and pneumatic rammers, and in particular of those with a vibrating frame.
  • Its object is a machine for ramming the ballast of railway lines, of the type comprising means controlled by a fluid under pressure for producing the motions towards one another and away from one another of at least one pair of ramming tools, characterized in that at least one member ensuring the mechanical interdependence is provided to connect the two tool-carrying arms of a same pair of tools, in order to ensure a conjugated motion of these tools, this member,
  • This vibrating frame is secured by means of damping components 13, on a frame which has not been shown and which is mobile vertically in order to ensure the sinking motion of the tools 4 into the ballast, the extraction of these tools from the ballast and to allow them to be lifted above the sleeper 5, in order that the machine and with it the tools 4 may be moved over to the next sleeper.
  • a vibrator constituted in the embodiment shown by an electric motor 10 driving an eccentric 9, is secured to the frame 12 and consequently imparts to the latter a vibrating motion which it transmits to the arms 1 and consequently to the tools 4.
  • This vibrator could be of a type different from that comprising an unbalance and an electric motor.
  • the arms 1 are connected to one another so as to be mechanically interdependent by a member, constituted in this embodiment by a rod 14, articulated to points 15, respectively 16 of the arms 1, preferably situated at equal distances from the articulations 6, but the one above and the other below the respective articulation. It is easy to understand that thus, when the fluid under pressure is introduced into the part of the cylinder 8 which is situated to the right of the piston 7, the tools 4 are not only compelled to move towards one another, but that in addition, the motion of these tools can, according to the proportions chosen for the different parts, be practically symmetrical within the extent of the working movement. An abnormal swinging motion of the toolcarriers under the influence of the weights concerned and above all under the action of the unequal resistances encountered by the two tools 4 in the ballast, is thus avoided.
  • the interconnecting rod can be provided at 14a, i.e., symmetrically with respect to the rod 14, as shown by the dot and dash lines.
  • the axis of the piston 7 and cylinder 8 controlling the opening and closing motion of the tools could be arranged obliquely, for instance in order to allow the articulations 3 and 6 of the right-hand arm 1 to be replaced by a common articulation.
  • This construction would allow the articulations 6 of the left-hand arm and 16 to be arranged at the same height above the ballast.
  • the shape of the vibrating frame 12 would in that case have to be modified in consequence, the right hand point 6 (coinciding with 3) would. be placed higher than the left-hand point 6 and that part of the right-hand arm 1 situated above the articulation 6 would be suppressed.
  • the vibrating. frame 12 could. obviously be made. to carry more than one pair of. tool-carrying, arms-..
  • the invention is) not limited to the case of a vibrating toolecarrying frame;
  • the vibration oh the tools could also be controlled individually for each tool.
  • Ramming apparatus comprising opposed ramming; tools; tool carriers supporting, said rammingtools, a sup porting frame, each: oi said tool carriers being pivoted on said frame, piston and cylinder means coupled to said: tool carriers on thesarneside'of' the: connection between thetool. carrier and theframe and. responsive to a pressure medium for oscillating said. tools toward and away from each other, and a connecting rod connected solely between said tool carriers, saidrodv being connected to anemone 4 one carrier above the connection of the latter to said frame and to the other carrier below the connection of the latter to said frame and being spaced the same distance from the pivot connection point between the tool carrier and the frame, said rod insuring a correlated movement of said carriers.
