Definitions

  • the subject matter described relates to a cribbing system and method for clearing a pathway.
  • Rail vehicles travel along rails, or tracks, that are placed along a pathway from a first location to another location.
  • care may need to be taken to ensure the rail is securely fastened into the ground. Unsecure rails can cause undue wear, a bumpy ride, or a derailment. As a result, care may need to be taken when placing tracks along a pathway.
  • a cribbing vehicle may be utilized to smooth a pathway of debris, rocks, and other undesirable materials within the ground or mud so that the rails, or tracks, can be secured into the ground utilizing anchors.
  • the smoothed-out area may be referred to as a crib that may be formed by the cribbing vehicle.
  • the cribs are formed because the anchor machine needs space in between the ties of the track to get a work head and anchors into the correct position on a rail. If a cribber vehicle is unable to clear debris, mud, packed ballast, etc. from the position it may be difficult to properly secure the anchor.
  • the work head of the anchor machine must correctly operate even through rocks, mud, debris, and the like. Additional wear, and early replacement of the anchor machine, may occur. It may be desirable to have a cribbing system that has relatively decreased wear on the cribbing equipment and anchoring equipment and that may affect the securing of track.
  • a cribbing vehicle in one or more embodiments, includes a vehicle frame and a primary cribbing device coupled to the vehicle frame and having a work head may move between rails of a track.
  • the cribbing vehicle may include an auxiliary cribbing system removably coupled to the vehicle frame in spaced relation to the primary cribbing device and having a push arm may move between a first tie and second tie of the track.
  • an auxiliary cribbing system in one or more embodiments, includes a kicker frame, a first actuating member coupled to a vehicle frame at a first actuating member first end, and coupled to the kicker frame at a first frame pivot at a first actuating member second end, and a second actuating member coupled to the kicker frame between a second actuating member first end and a second actuating member second end, and coupled to a push arm at the second actuating member second end.
  • the push arm may move from a travel position where the push arm may be coupled to a vehicle frame at a push arm first end and at a push arm second end, to a ready position where the push arm may be coupled to the vehicle frame at only the push arm first end, and to a working position wherein the push arm may be at least partially under a rail of a track.
  • a method of cribbing ground for securing rails of a track to the ground includes performing, with a primary cribbing device, an initial cribbing between a first tie of a track and a second tie of the track between rails of the track.
  • the method may provide, after the initial cribbing, performing a supplemental cribbing between the first tie of the track and the second tie of the track with an auxiliary cribbing device, including cribbing under a rail of the rails of the track.
  • Embodiments are disclosed herein that relate to a cribbing system that can be coupled to a vehicle frame of an existing cribbing vehicle that clears cribs of leftover debris after the cribbing vehicle smooths the pathway.
  • Leftover rock, ballast, packed mud, and the like may be rooted out using a push arm and a clearing head may engage and capture rock, debris, and the like.
  • Additional or auxiliary cribbing may prepare the ground for application of anchors. Overall, this may reduce or eliminate wear on the anchoring machining during use as well as provide other technical effects.
  • Figure 1 illustrates a side view of a cribbing vehicle 100 that moves along a pathway 102 to clear the pathway.
  • the pathway may be cleared of snow, ice, rock, debris, mud, and the like.
  • a track, or rail may be anchored.
  • the cribbing vehicle 100 of Fig. 1 is illustrated as including wheels 104. Still in other example embodiments, the cribbing vehicle may move using tracks, rails, sliding, etc. to form a crib along the pathway.
  • the cribbing vehicle includes a vehicle frame 106 on the wheels. In one example the wheels may engage and move along a previously laid track 108 and can engage the rails 110 of such track for movement.
  • the cribbing vehicle may include a primary cribbing device 112 coupled to the vehicle frame and that has a work head frame having a longitudinal extent and a lateral extent that may be mounted laterally on the vehicle frame and may be reciprocally movable vertically relative to the rails between a working position and a travel position.
  • the primary cribbing device may be coupled to the vehicle frame by being of one-piece construction with the vehicle frame, secured to the vehicle frame via welding, or other techniques, removably securing the primary cribbing device to the vehicle frame with bolts or other fasteners, or the like.
  • the primary cribbing device and the vehicle frame may be formed as a unitary structure formed from a single piece or body.
  • the primary cribbing device and the vehicle frame may be formed as a homogenous single component, rather than a non-homogenous component or a component formed by two or more separate bodies that are then combined with each other.
  • the homogenous component may have the same consistency and/or chemical makeup throughout the entirety or substantially all of the component.
  • the work head frame may be raised and lowered, including by use of hydraulic cylinders, a rack and gear arrangement, levers, cables, or the like.
  • the working head frame can operate in other manners than reciprocally, but in each instance, the working head frame functions to smooth or condition the pathway.
  • the smoothing or conditioning may include removing debris, or other materials, within the pathway.
  • the cribbing vehicle may include an auxiliary cribbing system 114 to be described in greater detail in relations to Figs. 2-5 .
  • the auxiliary cribbing system in one example can be removably, or detachably, coupled to the vehicle frame of the cribbing vehicle.
  • the auxiliary cribbing system may be bolted to the vehicle frame.
  • the auxiliary cribbing system can be screwed, clamped, adhered, etc. onto the vehicle frame.
  • the auxiliary cribbing system may be in spaced relation to the primary cribbing device. To this end, a single cribbing device with multiple actuating members cannot be considered both the primary cribbing device and the auxiliary cribbing system.
  • the auxiliary cribbing system may be located behind, or after, the work head frame in relation to the forward direction of movement of the cribbing vehicle. In an alternative example, the auxiliary cribbing system may be in front of, or before, the work head frame in relation to the forward direction of movement of the cribbing vehicle. In one example, the auxiliary cribbing vehicle includes a push arm and clearing head 116 that have a different size and shape compared to the implement that clears debris, rocks, etc. of the work head frame.
  • the auxiliary cribbing system may generate relatively more force at the clearing head where the ground, rock, debris, mud, ballast, etc. is engaged as compared to the implement of the work head frame that engages the ground, rock, debris, mud, ballast, etc.
  • the amount(s) of force may, in some embodiments, be selected by the controller and may be based on situation specific parameters.
  • the clearing head of the auxiliary cribbing system engages the ground, rock, debris, mud, gravel, ballast, etc. may use a different motion than the motion used by the implement that engages the ground, rock, debris, mud, ballast, etc. of the implement of the work head frame.
  • the auxiliary cribbing system may provide supplemental movement, force, clearing, or action that may differ from that of the work head frame.
  • the amount of rock, debris, mud, ballast, etc. removed from a pathway may differ compared to a situation where only the work head frame is utilized. This may condition the pathway for relatively improved insertion of anchors.
  • the anchors may be inserted into a substrate, such as the ground of the pathway, by an anchor machine.
  • Other embodiments may further differentiate the cribber from the implement.
  • Other suitable differentiations may include a vibratory device, a fluid dispenser, a compressed air blower, and the like, arranged on or in conjunction with the operation of the inventive cribber.
  • a suitable vibratory device may include tines or brushes and may vibrate and/or rotate to aid in the cribbing effort. The vibrating and/or rotating may be selectively activated by the controller.
  • a suitable fluid dispenser may be used to aid in the control of airborne dust generation, for example, and may be selectively operated by the controller.
  • a compressed air nozzle may blow smaller particles in a determined direction to aid in the cribbing and may be selectively operated by the controller.
  • Figs. 2-5 illustrate an auxiliary cribbing system 200 ( Fig. 2 ) and how the auxiliary cribbing system operates as the auxiliary cribbing system moves from a travel position ( Fig. 3 ) to a ready position ( Fig. 4 ), and finally to a working position ( Fig. 5 ).

  • the auxiliary cribbing system 200 attaches to the vehicle frame 202 of a cribbing vehicle 204.
  • the cribbing system may be detachably, or removably, coupled to the vehicle frame allowing the attachment and removal of the auxiliary cribbing system.

  • the auxiliary cribbing system includes the kicker frame that may be coupled to a push arm 208 such that the push arm moves in relation to the kicker frame of the cribbing system to engage the ground to provide cribbing functionality.
  • the push arm may be generally c-shaped, or has an arcuate body 210 that arcs from a push arm first end 212 at a main pivot 214 to a push arm second end 216 that terminates in a cribbing head 218.
  • the arcuate body 210 can include a roughened surface, patterned surface, toothed surface, or the like to facilitate the movement of the push arm through the ground 220.

  • the cribbing head can be relatively flat and rectangular in shape.
  • cribbing head may have a triangular cross-section, or be formed as a wedge.
  • the cribbing head may have a smooth surface, a roughened surface, have teeth, grooves, or the like.
  • the cribbing head may be a detachable implement where different cribbing heads are made for different ground types. So, in one environment the ground may be particularly rocky, whereas in another environment may include compact mud, or excess clay. In this manner, a cribbing head designed to best provide cribbing can be selected and secured to the push arm for use.
  • the auxiliary cribbing assembly additionally may include a first actuating member 232 secured to the vehicle frame of the cribbing vehicle at a first actuating member first end 234 and coupled to the kicker frame of the auxiliary cribbing assembly at a first frame pivot 236 at the first actuating member second end 238.
