Definitions

  • ABSTRACT The advancement of a mobile track working machine from operating station to operating station is accurately controlled by the combined use of a control element actuatable by a selected track part, such as a tie spike or bolt, a signal pulse generator operatively associated with the control element and producing signal pulses indicating the distance of the advancement, and a signal pulse recording instrument connected to the generator and receiving the signal pulses therefrom upon actuation of the control element by the selected track part.
  • a control element actuatable by a selected track part, such as a tie spike or bolt
  • a signal pulse generator operatively associated with the control element and producing signal pulses indicating the distance of the advancement
  • a signal pulse recording instrument connected to the generator and receiving the signal pulses therefrom upon actuation of the control element by the selected track part.
  • the present invention relates to improvements in mobile machines carrying tool means for working at spaced consecutive operating stations along a track comprised of rails fastened to ties.
  • the advancement of such machines from station to station is controlled by a control element actuatable by a selected track part, and the lowering of the tool means into an operating position may also be so controlled.
  • a signal pulse generator operatively associated with the control element, which generator produces signal pulses indicating the distance of advancement of the machine and a signal pulse recording or indicating instrument connected to the generator and receiving the signal pulses therefrom upon actuation of the control element by a selected track part.
  • control element By combining the control element, the pulse generator and the recording instrument, whose recorded or indicated signal pulses are used to control the advancement of the machine, the control element is responsive to the signal pulse generator and the machine advancement is responsive to the recording instrument signals. This makes an-accurate advancement of the machine fully automatic even when the crib widths or distances between the track ties are irregular, and even without any intervention by an operator. All that is needed is to switch on the control system at the beginning of an operation and to switch it off at the end, all adjustments during the operation being fully automatically controlled, if desired.
  • an electrical control circuit connects the control element and the signal pulse generator to the recording instrument, and actuation of the control element by the selected track part produces an initiating control signal opening the circuit to the transmission of the signal pulses from the generator to the recording instrument.
  • an initiating control signal opening the circuit to the transmission of the signal pulses from the generator to the recording instrument.

  • FIG. 9 is a schematic side view of a mobile machine for connecting and disconnecting tie fastening elements incorporating the present invention.
  • FIG. 10 is a similar side view of a modified machine of this type.
  • a generally conventional mobile track tamper l is shown to comprise a frame mounted on running gears 2, 2 over a track including rails 4 fastened to ties 3.
  • a track tamping unit 5 is mounted on a tamping tool carrier 6 which is vertically movably supported on .the tamper frame, the reciprocating vibratory tamping tools of the tamping unit being arranged to tamp ballast under each tie.
  • a hydraulic motor 7 is connected to the tamping tool carrier for vertically moving the same to place the tamping unit into and out of its operating position.
  • a brake 8 is shown associated with the rear wheels of the tamper for stopping the same intermittently while a selected tie is tamped.
  • a hydraulically operated track jack 9 is mounted on the front end of the tamper frame, the jack including pairs of rail gripping rollers engaging the track rails. All of this structure is entirely conventional.
  • An odometer wheel 11 is mounted on the tamper frame and runs on a rail 4 to measure the distance covered by the tamper during its advance in the working direction, the odometer wheel being associated with an inductively operating signal pulse generator 12.
  • the signal pulse generator is connected to an indicating instrument 13 on the tamper to transmit the generated pulse signals thereto, the indicating instrument comprising two indicators in the illustrated embodiment, the indicator I4 visibly showing the distance the tamper has advanced from the point when the pulsating control element 10 has signalled to the start of braking the advance of the tamper, and the indicator l5 visibly showing the distance the tamper has advanced from the signal point to the time the tamping tool carrier is lowered.
  • the pulse signal generator 12 operates so that it generates a pulse signal for given equal distance units, for instance one signal for each centimeter or inch of advancement, so that the indicators will visibly show the total distance of advancement in such distance units.
  • the control element is actuatable by selected parts of the track and, in the illustrated embodiment, is a pulsating element or pulsator.
  • Pulsators are commercially available instruments which, in conjunction with other electrical circuit elements, include inductive coils which produce a pulsating circuit in the absence of metallic parts. If a metallic part or body comes close to the pulsator, the magnetic circuit thereof is influenced by turbulent flows so that the pulsation is discontinued and the circuit emits a control signal.
  • the pulsating control element 10 is so mounted on the tamper frame that it will emit a control signal each time its magnetic circuit is interrupted by a metallic tie fastening element, such as a spike or a bolt. This produces the initiating signal for measuring the distance of advancement of the tamper, as hereinabove indicated.
  • the pulsating control element 10 is mounted on the tamper frame about 50 cm or inches ahead of the center line of the tamping unit 5.
  • the pulsator 10 is positioned between two ties in a crib and is, therefore, not actuated by a tie fastening element when the tamper is in the tamping position shown in full lines in FIG. 1.
  • the tamper operates as follows:
  • the tamping tool carrier 6 is raised by hydraulic motor 7 and, in a known manner, a limit switch is actuated automatically to advance the tamper (see, for instance, U.S. Pat. No. 2,976,816, dated Mar. 28, 1961, and U.S. Pat. No. 3,127,848, dated Apr. 7, 1964). While this advancement causes the pulse generator 12 to transmit signal pulses corresponding to the distance units measured by odometer 11 over electric circuit line 16 connecting the pulse generator 12 to the indicating instrument 13, a circuit breaker in line 16 prevents the signal pulses from being received by the instrument so that the advance is not indicated.
  • the indicator 14 is connected to the brake 8 by electric circuit line 19 which includes a relay.
  • the indicator actuates the relay in line 19 to operate the brake.
  • this predetermined distance is 20 cm or 8 inches but this distance may be adjusted to any desired value, depending primarily on the width of the cribs, by means of an adjustment element 18.
  • it takes the hydraulic brake about 30 cm or 12 inches to bring the tamper to a complete stop, the entire distance of the tamper advancement since the initiating signal was emitted from pulsator 10 being visibly shown on indicator 15.
  • This predetermined distance may also be adjusted to a desired value by adjustment element 20, such adjustment also taking into account the time required for lowering the tamping tool carrier 6 upon stoppage of the tamper.
  • the electric circuit lines 21 connects the indicator 15 to the hydraulic motor 7 so that the same will lower the tamping tools into operating position in the ballast when the indicator 15 has shown the pre-set value.
  • this arrangement Compared to the control of the tamper advancement and lowering of the tamper unit solely in response to the measured distance of tamper advance, this arrangement has the considerable advantage that any errors occurring at any one intermittent working stage are not accumulated from one stage to the next. Rather, if such an error occurs at one stage so that the tamping unit is not perfectly centered over a tie to be tamped at that stage, this error does not influence the advancement of the tamper during the following stage because each measurement of the advancement distance begins anew at zero. Furthermore, the tamper operator can read any error from the pre-set values on the indicators so that he has the opportunity to correct such errors by manual operation of the controls.
  • control device which may be connected to the indicating instrument or used instead of it, such control device computing any deviations from pre-set values and automatically controlling the speed, braking, etc., in response to such computations, similarly to the manner described hereinbelow in conjunction with the embodiment of FIGS. 2 and 3.
  • the pulsator 10 is centrally arranged in respect of the tamping unit 5, i.e., it is mounted on the tamper frame intermediate the two tamping tools so that it is in vertical alignment with the tie being tamped thereby.
  • the pulsator 10 is mounted on an axle 22 which also carries an odometer wheel '23 which is in rolling contact with a rail 4.
  • a signal pulse generator 24 is connected to the odometer wheel and generates signal pulses in response to distance units measured thereby.
  • the magnetic circuit of the pulsator is indicated in broken lines in FIG. 3, its actuation by tie fastening bolt 25 being clearly illustrated.
  • An electric circuit line connects the signal pulse generator 24 to indicating instrument 26 to transmit the generated signal pulses thereto.
  • the indicating instrument has a first visible scale 27 for showing deviations from the normal crib width, i.e., distance between adjacent ties, at the right rail, a second visible-scale 28 for showing the distance of tamper advancement along the right rail, a third visible scale 29 for showing deviations from the normal crib width at the left rail, and a fourth visible scale 30 for showing the distance of tamper advancement along the left rail.
  • a totalizer 33 is connected to the indicating instrument to compute any deviations shown on scales 27 and 29 and, in response to such computations, automatically to adjust the speed of the forward movement of the tamper and/or to initiate
  • the indicating instrument 26 shows the distance traveled by the tamper from the beginning of the tamper movement, the indicators showing the deviations of the positions of the ties from the norm. These recorded deviations are used for the automatic control of the machine.
  • While visibly indicating instruments have been illustrated because of their advantage in permitting an operator to make ready adjustments upon reading the indication of the distances traveled by the tamper, it is fully within the scope of the present invention to replace these instruments by simple recording devices, the recorded values being used for the control of the tamper movement.
  • FIG. 4 shows that the controls of this invention may also be effectively used in tampers combining a first tamping unit 5 arranged to tamp ballast under a tie and a second tamping unit 35 arranged to tamp the ballast in the crib between two ties, such as shown in U.S. Pat. NO. 3,111,909, dated Nov. 26, 1963.
  • the arrangement of FIG. I is duplicated for the surface vibratory tamper 35, Le, its lowering into the tamping position is also controlled by a pulsator l0 emitting its initiating control signal which is transmitted to a circuitbreaker in the electrical circuit line feeding the pulse signals from pulse generator 12 to indicating or recording instruments 13, 13, a single pulse generator being provided for both instruments. 7
  • the invention is applied to the operation of a tamper having a twin tamping unit comprising two commonly driven tamping tool assemblies 36, 37 for tamping two adjacent ties simultaneously, such as shown in U. S. Pat. No. 3,357,366, dated Dec. 12, 1967.
  • the pulsator 10 is spaced ahead of the twin tamping unit in the operating direction of the tamper by twice the width of the cribs, measured from the center of the tamping unit.
  • the control operates in the same manner as described in connection with FIG. 1.
  • control element is not a pulsator but a wheel 38 which is pivotally mounted on the tamper frame to run on the ballast next to rail 4.
  • the freely pivotally mounted wheel 38 will be lifted by the ties 3 as the wheel moves into contact therewith, the raising of the wheel operating a switch to produce an initiating control signal.
  • wheel 38 operates the signal pulse generator 39 so that the same begins to emit a series of signal pulses corresponding to the distance units (centimeters or inches) traveled by the tamper.
  • FIG. 6 shows the tamper in the position when it has moved 40 cm since the tamping unit 5 was in the lowered tamping position.
  • FIG. 7 shows the rear portion of the tamper after the tamper has advanced 45 cm from the last preceding tamping position, at which point brake actuation is initiated.
  • FIG. 8 shows the front portion of the tamper after it has advanced 65 cm to the next tamping position wherein the tamping unit 5 is lowered again.
  • the tamper will automatically move forward as the tamping tool carrier 6 is raised out of the ballast, the signal pulse generator 39 transmitting signal pulses to indicating or recording instrument 40 to show the number of centimeters or inches the tamper is advancing.
  • the adjustment element 41 has set the instrument 40 to the desired distance of tamper advancement before the brake 8 is to be operated (45 cm in the illustrated embodiment), and the adjustment element 42 has set the desired distance before the tamping tool carrier 6 is to be lowered (65 cm in the illustrated embodiment) so that the stopping of the tamper and the positioning of the tamping unit is correspondingly controlled.
  • the control wheel 38 runs up the edge of an adjacent tie to emit the control signal which returns the instrument setting to zero to star-t the next control stage. It may be desirable to delay this zero setting somewhat so that an operator has the opportunity to correct the setting of the indicating instrument 40 in such cases where the crib width is narrower than the norm and the control wheel 38, therefore, is lifted prematurely to emit a faulty control signal.
  • FIGS. 9 and 10 schematically show machines of this general type, the machine illustrated in FIG. 9 being designed for assembling and disassembling rail attachment means 43, which may include tie plates, bolts and nuts, such means being used to fasten the rails 4 to ties 3.
  • Rail attachment means 43 which may include tie plates, bolts and nuts, such means being used to fasten the rails 4 to ties 3.
