Definitions

  • ABSTRACT In a mobile track renewal apparatus which includes a series of cooperating tie conveyors leading to and from the track section where ties are to be picked up and/or laid, control means is arranged in the tie conveyor path and actuatable by a tie in the path for controlling the movement of selected conveyors.
  • the present invention is particularly advantageous in connection with such an apparatus disclosed and claimed in our copending application Ser. No. 849,406, filed Aug. 12, 1969, which comprises a support frame elongated in the track elongation direction and supporting a plurality of track tie conveyors for transporting the ties to and from the working location where means is provided for taking up and laying ties.
  • the entire conveyor system forms a structural unit whose one end is supported on a carrier vehicle which preferably runs on the track rails and may consist of a transport and storage vehicle for the ties while its overhanging forward portion is supported on running gears, such as those more fully disclosed and claimed in our copending application Ser. No. 864,384, of even date.
  • Such a control requires careful coordination of tie sensors positioned along the tie path for the actuation of control circuits operating selected ones of the conveyors in timed sequence.
  • conveyor movement control means arranged in the conveyor path and actuatable by a tie in the path for controlling the movement of selected conveyors.
  • control means are preferably constituted by elements or sensors mechanically movable by a conveyed tie in contact therewith to actuate a switch operating the respective control circuits which stop and move the various types of conveyors of the system. It will be useful to mount such control means between adjacent ones of the conveyors in the tie conveyor path so that they are automatically actuated by the moving ties.
  • FIG. 1 is a top view of the apparatus
  • FIG. 2 is a side view taken in the direction of arrow II of FIG. 1;
  • FIG. 3 is a front or sectional view taken along line IIIIII of FIG. I;
  • FIGS. 4 and 5 show details of certain controls, taken along lines lV-IV and V-V of FIG. 1, respectively.
  • the endless conveyor band 8' on turntable 8 cooperates with the elongated conveyor 1 to receive the ties 3 therefrom, being pivotal about an axis transverse of the track into and out of the plane of the conveyor I (see small vertical arrow in FIG. 2), the entire turntable being below the level of the raised track rails 2 and the turntable being rotatable about a vertical pivot extending through the centerline of the track.
  • the conveyors 1 and 8 form a unit which rests in part on the newly laid track rails rearvvardly of the illustrated forward portion of the apparatus, not shown herein but fully described in the above-mentioned copending application Ser. No. 849,406.
  • the forward portion of the apparatus rests on the track-free ballast, being supported thereon by a running gear including full-track 9 and wheels 9', 9, which running gear may be steered by operation of the pressure fluid operated drive 9 all of which is more fully described and claimed in our copending application Ser. No. 864,384, of even date.
  • the length of the endless band 8 is less than that of the ties 3, and two elongated conveyor bands l2, 12 are mounted laterally adjacent the turntable at diametrically opposite sides thereof to receive the ends of the ties after the turntable has been turned
  • the conveyors 12, 12 extend in the direction of track elongation and their spacing is such that a transversely extending tie may be supported on these conveyors.
  • Means is provided for vertically moving the conveyor 12, 12 into and out of the plane of the endless conveyor band 8' on turntable 8 whereby a tie may be supported selectively by the turning conveyor and the elongated conveyor 12, 12 for transferring ties between them.
  • the conveyors l2, 12 may be lowered to the level of another conveyor means 13, illustrated as another pair of endless conveyor bands, whereon the tie is deposited for moving the same to a pair of roller conveyors 25, 25.
  • the short final conveyor means 25, 25 supports a single tie at a time while the tie extends transversely to the direction of track elongation.
  • a forklift tie support is associated with the final conveyor means, being mounted between the two roller conveyors 25, 25 for transferring individual ties between the track section, i.e., to or from the ballast, and the roller conveyors.
  • the forklift tie support 5 is vertically adjustable and pivotal. To facilitate transfer of ties between the roller conveyors and the forklift 5, the roller conveyors are adjustable in relation to the forklift, being pivotal so as to open the path for downward movement of the forklift to enable the latter to deposit a tie on the ballast.
  • a series of conveyor movement control means are arranged in the path of ties 3 thus to program the transport of the ties rationally from conveyor 1, which receives or transfers the ties from or to a tie transport and storage car (not shown) to forklift 5 which deposits or picks up a tie on or from the ballast.
  • This control system will now be described in the sequence of operations as a pair of ties is moved down conveyor 1 towards forklift 5, the new ties 3 being provided with rail support plates 3" to which the rails are bolted on the ties.
  • the switch 26 is depressed by a tie 3 moving thereover on its way to turntable 8 and, in the depressed position, it is ready to actuate an electrical control circuit for stopping movement of the conveyor band 1.
  • actuation of the circuit in the ready-position of switch 26 will be effectuated only in response to the actuation of subsequent control means in the path of the ties, to be described hereinafter. At such time, the circuit will be actu ated to stop further movement of conveyor band 1 and thus to preventjamming of ties.
  • Stops 27, 27 are associated with turntable 8 in direct alignment with elongated conveyor 1 in the path of the ties moving therefrom to and over endless conveyor band 8', the stops being so spaced from the turntable that the ties 3 will contact the stops when the centers of the ties are in alignment with the pivot center of the turntable, i.e., when the ties are symmetrically supported on the endless conveyor band 8', with the tie ends extending equally from both ends of these conveyor bands, as shown in FIG. 1.
  • Contact of the ties with the stops operates switches at the stops for actuating a control circuit operating the rotational movement of turntable 8 as well as simultaneous pivoting of the turntable from the illustrated oblique position in alignment with conveyor 1 to a horizontal position parallel to succeeding conveyor 12, 12.
  • the protruding ends of the now transversely positioned ties are in vertical alignment with the pair of conveyor bands 12, 12, which bands run parallel to the direction of track elongation and are positioned at diametrically opposite sides of the turntable.
  • one of the ties contacts switch 28 which actuates control circuits which stop further rotation of the turntable, cause the conveyor 12, 12 to be raised to the level of ties 3 so that the ties will rest on this conveyor pair and, if the conveyor bands of this conveyor pair are not continuously moved, the switch 28 actuates an additional circuit causing movement of the bands so that the ties begin to be moved off the turntable in the direction of track elongation in a position transverse to the track.
  • the vertical movement of the conveyor l2, 12 is timed by its control circuit so that, after it reaches its highest level to receive the ties from the turntable 8, it automatically is lowered again to the level of succeeding conveyor means 13, 13.
  • the ties are transferred to the overlapping coplanar short conveyor bands 13, 13 which move them on.
  • a depressable sensor element 29 Centered between the conveyor bands 13, 13 which are arranged parallel to, and between the conveyor bands 12, 12 is a depressable sensor element 29.
  • the element 29 which is a switch actuating a control circuit causing the turntable 8 to rotate back to its original position, wherein the endless bands 8' is in alignment with elongated conveyor 1, and to pivot the turntable into its oblique position in coplanar alignment with conveyor 1.
  • this switch 29 may also actuate the control circuit operating movement of conveyor 12, 12 so as to stop movement of the endless bands thereof.
  • the short conveyor bands 13, 13 transport the ties to the pair of roller conveyors 25, which advance the ties to pivotal stop 30 which, as shown in FIG. 5, is pivoted forwardly by the tie contacting the same.
  • the sensor 30 is spaced from the end of conveyor means 13, 13 by approximately the width of a tie and, upon being pivoted by an arriving tie contacting the sensor, it actuates a switch operating a control circuit for stopping movement of the conveyor means 13, 13 so that only a single tie is positioned on roller conveyors 25, 25 at any one time.
  • the stops 31 are aligned transversely of the track in the path of the tie, and their position may be adjusted in the direction of track elongation, i.e., they may be transversely aligned so that they define a line perpendicular to the track elongation, which is the desired end position of the tie in a straight track section, or so as to define a line enclosing an acute angle with the perpendicular,
  • the stops 31 constitute a sensor establishing the desired end position of the tie on the ballast.
  • a switch 32 is mounted at the same location to be actuated by a sensing element 32' which senses the recess in the rail support plate 3" on tie 3, thus to establish the desired final position of the tie in lateral relation to the centerline of the track.
  • the vertical movement of the forklift is timed to be automatically reversed after it has reached its lowest point and the pivotal movement of the roller conveyors is timed to return .the roller conveyors to their original horizontal position after they have contacted stop 33.
  • the return of stop 30 into its original position causes the movement of conveyor bands 13, 13 to be resumed so that the second tie thereon is advanced to the roller conveyors, to repeat the above-described cycle of movements of the roller conveyors and forklift.
  • the conveyors 12 have moved a succeeding pair of ties to the conveyors 13 to continue an uninterrupted supply of ties to the track section while the apparatus advances therealong continuously to lay tie after tie.
  • the switches at sensors 29 and/or 30 and switch 26 are so connected in the control circuit which operates the movement of elongated conveyor 1 that switch 26, when depressed by a tie moving over it, will operate the circuit to stop further movement of conveyor 1 when the switches at sensor 29 and/or 30 is also actuated, i.e., if a tie rests on roller conveyors 25, 2S and a tie moves on conveyors 13, 13 over the sensor 29. in this case, the conveyor 1 is halted and further supply of ties is momentarily interrupted.
  • a track tie conveying means comprising a series of sequentially ar ranged, cooperating driven tie conveyors leading to and from a track section to be renewed in a tie conveyor path extending in the direction of track elongation, and tie conveyor movement control elements arranged between two adjacent ones of the conveyors and mechanically movable by a conveyed tie in contact therewith for driving selected ones of the tie conveyors, one of said tie conveyors being a moving conveyor elongated in said direction for transporting said ties extending in said direction, and another one of said conveyors is a cooperating adjacent conveyor movable around a vertical pivot for receiving the ties from the elongated conveyor and turning them into a direction transverse to the direction of track elongation, said control means including a control element arranged between the one and the other conveyor and being actuatable by a tie in contact therewith to stop the movement of the elongated conveyor.
  • said mechanically movable element being a switch.
