Definitions

  • the present invention relates to a railway machine for the rectification of the rail head.
  • grinding units for example each consisting of a rotary grinding wheel and its drive motor, are mounted in groups of three or four on pads arranged parallel and above the rows of rails. These pads are connected to the rolling chassis of these machines by vertical and longitudinal connecting members having the respective functions of lowering and raising them for putting them in and out of service and for driving and guiding them along the track during the advance in work.
  • the grinding units are mounted either all at the same angular position in a plane transverse to the track in order to all grind the same generatrix of the profile of the surface of the rail head, or each inclined at a small angle relative to the other in said plane so as to each rectify a generator spaced apart from the neighboring generator.
  • the orientation difference between the grinding units must be small to obtain a good quality of work and to minimize the width of the facets resulting from the grinding.
  • the invention aims to solve these problems.
  • the proposed solution consists in mounting on these machines tool-bearing skids with variable inclination in a plane transverse to the track, so as to allow the angular displacement of all the grinding units mounted on each skate around the profile of the surface. of the rail head, as will be shown later in detail.
  • this solution makes it possible to compensate for the insufficiency of the number of grinding units by a greater number of passes at angles of inclination as reduced as necessary between the grinding units mounted on each pad.
  • the machine represented in FIG. 1 is a vehicle for rectifying the running surface of the rails 1 of a railway track on which its rolling chassis 2 rests by two axles 3 and 4.
  • This machine of the so-called “compact” type, is autonomous and is equipped for this purpose with an energy center 5 supplying the energy necessary for its movement and for driving and controlling its grinding units 6, and two control stations 7, front and rear, in which are grouped together the command and control bodies.
  • the grinding units are grinding units 6, sixteen in number, mounted in groups of four on four pads 8 arranged in pairs on each row of rails, one after the other, between the axles 3 and 4.
  • Each shoe 8, arranged parallel and above a line of rails 1, is connected to the rolling chassis 2 by a jack 9 and by two drawbars 10 articulated to a console 11 fixed under said rolling chassis .
  • each shoe is articulated on a pivot 13.
  • a hydraulic cylinder 14 with two effects is interposed between each shoe 8 and the connecting element 12 is articulated to these two elements on two pins 15 and 16 forming with the pivot 13 a deformable triangle.
  • Each shoe 8 is structured in the form of a frame consisting of two longitudinal walls 17 connected by crosspieces 18 thus forming cells inside which are mounted the grinding units 6. These consist of a cylindrical rotary grinding wheel 60, here a lapidary wheel working in the field, fixed at the end of the shaft of an electric drive motor 19. Each motor 19 is fixed on a frame 20 comprising a slide 21 mounted on a vertical slide 22 fixed to the inner wall 17 of the frame of the shoe 8. An ⁇ -screw and handwheel 23 control makes it possible to adjust the height position of each slide 21, therefore of each grinding wheel 60, relative to the shoe 8.
  • each frame 20 forms with the axis of rotation of the grinding wheel 60 an angle D l preset according to the desired angular difference between the four grinding units thus mounted on the shoe 8.
  • the two chambers of the two-effect hydraulic cylinder 14 are connected to a hydraulic supply circuit, not shown, comprising a distributor with three positions, with double control and spring returners making it possible to adjust the inclination of the shoe 8 at an angle D 2. preset defined below.
  • the connecting element 12 is articulated by two fittings 24 and 25 to the two drawbars 10 shown in FIG. 1 and each shoe 8 is connected by an articulation 26 to the jack 9.
  • This jack 9 has the function here of raising the shoe 8 and adjusting the contact pressure of the latter on the track of rails 1.
  • a device for controlling the angle of inclination D 2 of each shoe 8 relative to the connecting element here a potentiometer 27, is mounted on the pivot 13 and is connected to an indicator dial 28 placed in the control stations.
  • control 7 of the machine to allow the operator to adjust and control said angle of inclination D 2 .
  • the machine according to the invention allows the rolling surface of the two rows of rails 1 to be rectified by grinding according to a working process illustrated in FIG. 4 and given as an example for the rectification of the rolling table of a UIC.60 rail.
  • the profile of the tread table is in the form of a curve formed by the connection of a central arc of large radius framed by two arcs of smaller radius, intercepted by an angle at the center O of 25.3 degrees and whose rope is 52 millimeters.
  • the four grinding units 6 are each tilted relative to the other by a small angle A 1 , A 2 , A 3 , so as to each grind a generator G 1 , G 2 , G 3 , G 4 , over a total angle B 1 equal for example to one third of the total angle 0, which represents an arc length of the order of 17 millimeters.
  • This arc length can be ground on the first pass of the machine by orienting the shoe 8 using the jack 14 at an angle D 2 (fig. 2) depending on the angle 0 and the angle B 1 .
  • the result of this first pass will be in profile in the form of an envelope with four facets connected of the order of 5 to 6 millimeters in width each.
  • the two other grinding pads 8 can either be used in the same way when only the tread table needs to be rectified, or used according to the same principle to also grind the connection leave with the inner flank of each row of rails, this leave also in the form of an arc.
  • This process which makes it possible to arrange the grinding units at very small differences in inclination between them on each pad, has the further advantage of obtaining an excellent result in the elimination of wave deformations of long wavelength, the four generators G 1 , G 2 , G 3 , and G 4 ground by the shoe 8 being very close to each other.
  • the inclination of the grinding units 6 is adjustable by mounting the motors 19 with pivoting on a pivot 29 carried by a console 30 secured to a special slide 31 mounted in the same way and having the same function as the slide 21 of the example illustrated in Figure 2 already described.
  • a double-acting hydraulic cylinder 32 is interposed between this slide and the motor 19 to control and adjust the inclination D 3 of each grinding unit 6 and is connected for this purpose to a supply circuit, not shown, comprising a distributor of the same type as that of the cylinder supply circuit 14.
  • a potentiometer 33 is mounted on the pivot 29 and connected to an indicator dial 34 to control the inclination of each grinding unit 6 in the same manner as for the inclination pad 8.
  • This variant makes it possible to adapt the angular offset A l , A 2 , A 3 (FIG. 4) between the units grinding 6 mounted on the pad 8 depending on the size of the arc B 1 , B 2 , B 3 that you want to grind with each pass. It is thus possible to reduce or increase the number of grinding passes to correct the running table of the rail 1 of FIG. 4 according to the degree of precision required.
  • the power supply circuit of the jack 14 comprises an angular angle advance control B li B 2 ' B 3 of the type step-by-step, controlled by reversing the direction of advance of the machine, between each grinding pass.
  • the control of the distributor of this supply circuit is slaved to a regulation loop in which the indicator device 28 and a device for displaying the selected angle value B 1 , B 2 ′ B are integrated. 3 ' itself actuated by the step-by-step command.
  • the invention is applicable to all types of grinding pads with the same advantages.
  • the device for control of their transverse inclination can be achieved by pivoting around a pivot carried by a liftable intermediate support equipped with said guide rollers, or by direct pivoting around the rollers.
  • hinge pivot 13 of the shoe can be replaced by any other equivalent pivoting member, such as for example a curvilinear slide or a combination of concurrent connecting rods creating a real or fictitious pivot axis.
  • the device for controlling the inclination of the skate can be reduced to simple travel limitation stops.
