' A 1,771/60 7 lairns. (6!. 194-7) This invention relates to the aligning of tracks for railroads and the like, and is more particularly concerned with a method for establishing lines of reference for track alignment, and with apparatus for performing the method.
In aligning a railroad track which has shifted in use, it is known to employ track lifting and ballast tamping machines which travel along the track. Such machines are equipped with track lifting or shifting devices which raise the tracks or shift them laterally. Tamping tools associated with the machine then tamp the ballast under the adjusted track section to fix the position of the latter. Operation of the machine is guided by a reference line which is laid out parallel to the desired course of the track. By measuring the distance between a track section and the reference line, the deviation of the track position from the desired position is readily established and the aligning operation may be controlled accordingly.
In a known arrangement which has been widely accepted because of numerous advantages over the earlier state of this art, a relatively heavy vehicle carries track lifting or shifting devices, which aredesignated as track moving meansfin the claims, and ballast tamping tools on a frame portion which overhangs thefr-ont wheels of the vehicle. While the vehicle wheels stand on a corrected or'aligned track section, the lifting or shifting devices and the tamping tools are spacedly superposed on a track section still requiring alignment. A measuring device mounted on the overhanging frame portion may in-' dicate the spacing between a fixed member of the vehicle and the track underneath, and thus provide guidance as to the amount of, track alignment needed.
While a fixed index mark on the vehicle frame may serve as a point of reference since the wheels of the vehicle stand on the corrected track section, it has been found that a more precise adjustment of the track position results from establishing a reference line one end of which is at a point of the vehicle frame spaced backwardlyfrom the tamping tools and the lifting or shifting devices. In the known arrangement, provisions are therefore made for a reference line which extends from a rearwardly displaced frame portion to a second vehicle placed Well forward on the unadjusted track section. The reference line may be provided by a beam of light but it is simplest to provide a flexible tension member such as a wire or" cable under tension which extends between'the two ve-' hicles.
The second vehicle may be normally stationary on the tracks and the first vehicle which is a movable tamping machine moves toward the second vehicle. The latter has to be shifted from time to maintain a minimum distance between the two vehicles. This mode of operation usually requires two operators, one to. remain at the controls of the tamping machine at all times and the other one to shift the second vehicle as required. It has also been proposed to interpose rigid push rods between the two vehicles so that the second vehicle will move at all times ahead of and with the tamping machine.
In the latter arrangement, the distance between the two vehicles is of necessity limited and fixed. Because the second vehicle stands on a track section which has not yet been corrected, and one end of the tension wire is drawing, during itsoperatiOn.
3,192,373? Patented July 6, 1965 ice fixedly fastened to the second vehicle, there is an inherent error in the position of the tension member. A deviation of the end portionof the wire on the second vehicle from the desired position results in a deviation of the Wire portion which serves as an index mark for indicating the desired position :of the tracks adjacent the first vehicle. The latter deviation will be smaller than that of the end portion and its magnitude decreases inversely with the distance from the second vehicle. It is thus desirable that thflJSECOlld vehicle be as far as possible from the first vehicle and further than would be practical with rigid rod connections.
Even where a relatively great length of track separates the two vehicles, significant errors will result if the second vehicle is positioned on a track portion which deviates to an exceptional extent from the desired position, and a worthwhile improvement in track alignment precision can be achieved bychoosing the location of the second vehicle judiciously. This is not possible in an arrangement in which the first vehicle, namely the tamping machine, moves continuously in steps from tie to tie, as it must, and the distance between the two vehicles is fixed by a rigid member.
It is the general object of the invention to combine the advantages of the several known arrangements briefly described above while avoiding their inherent shortcomings, and a more specific object to permit track alignment of high precision with relatively simple'means operated by a single'man. v
Another object is the provision of a track alignment arrangement of the two-vehicle type described, in which the second vehicle may be moved at will by the'single operator without leaving the tamping machine.
The exact nature of this invention as well as other ob jects and advantages thereof will be readily apparent from consideration of the following specification relating to the annexed drawing in which:
"FIG. 1 is a side-elevational view of a preferred embodiment of the track aligning arrangement of the in vention. I e k The vehicular track shifting and ballast tamping ma chine 1 rolls on rails 2 which rest on ties 3 and ballast 4. The section of the track'under the wheels of the tamping machine 1 was previously aligned by the machine which moves from thele ft toward the right, as viewed in the The desired position of the'tra'ck is established relative to a tensioned wire or cable 5 which is wound on a pulley or winch'6 oh the tamping machine approximately above the front w eels. The wire 5 extends forwardly from the' machine 1 and is fastened to a clamping'block 7 on a second vehicle 16 which is also movable on the rails 2.
The front portion of the tampingmachine 1 overhangs the front wheels and carries a sliding vertical indicator rod 8;. The bottomend of the rod rests on the track.
The relative position of its top end and of the wire 5 is thus a measure of the deviation of the position of the track from'theflesired position. A'hydraulic jack 9 is mounted on the front'wall of the machine 1 and is justed position of'the track is secured by the tamping tools 9 which push ballast under a tie adjacent the lifted track section; 'I'he'lifting device and tamping arrange- 0 ment are wellknown and will not be furtherdiscussed.
- The second vehicle 10 is equipped with an electrically driven pump 12 which provides pressure fluid at constaut pressure fluid at fixed maximum pressure to the motor 11. Alternatively, a pressure reducing valve may be installed in the conduit connecting the pump and the motor if the latter is of the turbine type so that only a predetermined adjustable amount of pressure fiuid is delivered to the motor. Many other devices are well known for providing a substantially constant maximum torque at the output shaft of the motor 11 which is coupled to a set of driven wheels of the second vehicle 19 by a pulley and belt transmission, thereby maintaining a substantially constant tension in the wire or cable 5.
It will be understood that the second vehicle it) may be equipped with conventional rail gripping clamps to arrest movement of the vehicle It The clamps, if provided, are preferably either electrically operated or fluidoperated by the pressure fluid output of the pump 12, and admission and release of the pressure fluid is controlled by a solenoid valve, or other electrically operated control valve.
The tamping machine or first vehicle 1 has a prime mover 13, such as a diesel or gasoline engine, the output shaft of which is coupled with the wheels 14 of the machine by a' transmission arrangement which includes a. clutch (not shown) and a chain 13 permitting the operator to move the machine along the track at will. A releasable belt 19 of the transmission arrangement causes rotation of the pulley or winch 6 at a peripheral speed equal to the peripheral speed of the wheels 14 when the machine moves along the tracks so that the effective length of the wire or cable is reduced by a length equal to the distance traveled by the machine when the latter moves toward the second vehicle 10,- and the wire remains uniformly tensioned even when the. second vehicle is sta tionary.
Power is continuously transmitted from the motor 13 to an electric generator 15 on the tamping machine. The current output of the generator is fed by a multiple conductor 16 to collector brushes (not shown) which transmit the current to corresponding multiple'insulated conductive cores 17 by the cable 5. The current transmitted by the conductive cores 17 energizes the pump 12 on the second vehicle 10.
It will be understood that. the electric circuit of the pump 12 also includes conventional switch gear at the operators station on the tamping machine for control of the pump '12. by the operator. The electrical actuators or electrically actuated control valves for the rail gripping clamps on the second vehicle, if such clamps are provided,
are also energized by the generator 15 and controlled by.
switches at the operators station on the tamping machine. Additional conductive cores 17 in the wire or cable' 5 provide the transmission of an electrical actuating or controlling signal between the two vehicles.
The above described apparatus is operated as follows:
The operator of the tamping machine drives the machine to the. desired location. During this movement along the tracks, the vehicle may be pushed by the tamping machine 1. He then starts the generator and sets the controls for the second vehicle 10 so that the latter will move ahead of the tamping machine 1, thereby unwinding 2. length of the cable 5 from the pulley 6. When the second vehicle 10 reaches a track section the level of which is near the desired level, the motor 11 is stopped and the pulley 6 is arrested by connecting it to the wheels 14 by the belt 19. A brief additional forward movement 4 of the second vehicle 10 then tightens the cable 5 and the position of the vehicle 10 may be fixed by clamps, if desired.
The track section underlying the overhanging front end of the machine 1 is raised by the jack 9 until the top of the rod 8 reaches a desired position relative to the wire 5, for example, touching the Wire. The track section is then secured in its adjusted position by tamping ballast under the tie 3 adjacent the jack 9. The jack is then released from the rail 2, the tamping tools 9' are withdrawn from the ballast 4 and the machine 1 is moved toward the right, as viewed in FIG. 1, until the tamping tools 9' are aligned with the next tie.
During this forward movement, the pulley 6 rotates clockwise in such a manner that the length of wire 5 Wound on the pulley is equal to the distance traveled by the vehicle 1. The wire 5 thus remains tensioned. If desired and necessary, an additional adjustment of wire tension may quickly be effected by releasing the clamps of the vehicle 19 and briefly actuating the motor 11.
When the apparatus illustrated is not equipped with clamps'on the second vehicle, the latter is held in a substantially fixed position by the wire 5 in cooperation with the motor 11 which is kept in continuous driving engagement with the wheels of the second vehicle and thereby longitudinally stresses the wire. Although the friction of the wheels 14 on the rails 2 together with the engagement of the pulley 6 with the wheels 14 by means of the belt 19 and chain 13 is normally adequate to prevent rotation of the pulley 6 by the forces transmitted by the wire 5, it is preferred to equip the pulley 6 with a releasable ratchet (not shown) which prevents unwinding of V the wire 5 from the pulley. During forward movement of the tamping machine 1, the wire 5 is wound on the pulley 6 by. the torque exerted by the belt 19 which is sutlictent to overcome the unwinding forces generated by the motor 11.
If desired, the transmission arrangement of the tamping machine 1 may be provided with additional means, such as a clutch coupling, permitting the wheels 14 to be disconnected from the prime mover 13 while maintaining the operative connection between the latter and the pulley 6. This will permit the tamping machine operator to control movement of the second vehicle 10 toward the tamping machine in a simple manner without ever leaving his control station.
The arrangement for control of movement of the second vehicle illustrated and described hereinbefore is used to advantage even where the wire 5 does not in itself provide .the reference line relative to which the position of the track is adjusted. The otherwise conventional arrangement in which a visual target is arranged on the second vehicle and'viewed from the tamping machine to define a line of sight relative to which the track is adjusted is greatly simplified if the movement of the target vehicle is controlled by the apparatus of the invention, including an elongated pliable tension member the two ends of which are secured to the two vehicles each of which is individually driven and under control of a single tamping machine operator.
Obviously, many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than specifically described.
