Definitions

  • ABSTRACT An advancement mechanism for horizontal earth boring machinery which can automatically advance or retract the boring unit without independent manipulation of the locking unit associated with the advance ment mechanism.
  • the device comprises a set of dogs pivotally mounted on the advancement mechanism so as to engage rails provided to support the earth boring equipment.
  • a variable volume pump is employed with a hydraulic cylinder to alternately advance the earth boring machine and the advancement mechanism.
  • a lever is employed which has the capability of automatically switching the direction of flow of the hydraulic pump to enable the progression of the total unit to be completely automatic.
  • This invention relates to advancement mechanisms for horizontal earth boring machines. More specifically, this invention is directed to an improved means for locking and unlocking the advancement mechanisms during the walking process and for controlling the walking process using the improved locking means.
  • Heavy-duty, horizontal earth boring equipment generally requires mechanical means for driving the boring unit and auger into and out of the intended horizontal shaft.
  • a rail or rails have been employed. These rails provide the means for aligning the unit as well as provide the base from which force is applied to both advance and retract the boring unit from the shaft. Advancement mechanisms have been among the methods employed to advance and retract these boring units along the rails.
  • a advancement mechanism is operated by first anchoring it to the track to provide a base for forcing the boring unit either toward or away from the shaft along the rails. When the boring unit has been moved the predetermined distance, the advancement mechanism is disengaged from the track and drawn along to the next position. This sequence is then repeated for as many times as required to cross the desired distance.
  • Advancement mechanisms heretofore employed to both advance and retract the boring units have required specific separate operations to either engage or disengage the advancement mechanism during each cycle.
  • This separate independent step requires the operator to stop the walking process of eachcycle to either engage or disengage the advancement mechanism. This procedure necessarily slows the overall process of drilling a shaft. Further, the walking process cannot be totally automated using this separate engagement step without excessive mechanical complication.
  • An object of the present invention is to provide a advancement mechanism for a horizontal earth boring machine which will automatically engage and disengage itself from the supporting rails during the walking process.
  • This walking process can be accomplished in either direction.
  • Rail engaging dogs are provided which, when unconstrained, are free to move from engagement with the rails.
  • Selective constraint means are provided which prevent the dogs from disengaging when the advancement mechanism is moved in either one or both directions along the rails. Because the dogs can be selectively constrained from disengagement in a given direction, the advancement mechanism will automatically disengage, advance, and lock in each succeeding position as required.
  • a second object of the present invention is to provide an automatic advancement mechanism which will selectively allow the walking process to be performed in either direction along the rails. Because of the selective constraint means, the advancement mechanism can be made to automatically perform the cycle of disengagement, advancement, and lock for both advancement and retraction along the rails. Thus, a direction of walking is first selected. The advancement mechanism is then driven by a hydraulic cylinder to perform its function without further independent manipulation of the locking means.
  • a further object of the present invention is to provide a practical means for automatically actuating a cylinder or other device which is used to alternately force the advancement mechanism toward and then away from the boring unit to accomplish the walking process. Because the operation of the advancement mechanism has been automated through the present invention, a further advantage is obtained.
  • the walking operation may be totally automated with little or no further mechanical complication using a variable volume pump to drive a hydraulic cylinder and a simple control lever.
  • a advancement mechanism is herein disclosed which automatically locks and unlocks to accomplish the walking process and provides for easy adaptation to a wholly automatic advancement system for a horizontal earth boring machine. Further objects and advantages will become apparent from the description herein.

  • the blocks 104 and 106 are placed on an actuation member or shaft 108 in such a manner that the longest dimension of one block is perpendicular to the longest dimension of the other.
  • the blocks 104 and 106 and the shaft 108 are capable of rotating 90 in order to allow for the positioning of each of the blocks 104 and 106 in a horizontal position.
  • it operates to prevent the dogs 72 from rotating in one direction.
  • the blocks 104 and 106 are perpendicularly oriented, when one of the two blocks is horizontally disposed so as to prevent rotation of the dogs 72 in a first direction, the other block is vertical and thereby allows rotation of the dogs 72 in the opposite direction.
  • the two modes provided by rotation of the blocks 104 and 106 are shown in FIGS. 5 and 6.
  • the shaft 108 is pivotally mounted in bearing 110. Spacer collar 112 helps to properly position the shaft 108 in the walking beam.

  • Lever 116 is positioned 45 from the longest dimension of each block 104 and 106 in order that one or the other of blocks 104 and 106 will be horizontally disposed when the lever 116 is in either of the notches 126 located 45 from the vertical.
  • the blocks 104 and 106 are each rotated 45 from vertical. In this position, both blocks 104 and 106 interfere with the rotational motion of the dogs 72 which in turn prevents the disengagement of the dogs 72 from the rails 16 in either direction.
  • a hydraulic cylinder 18 of the double action type provides means for both extension and retraction of the advancement mechanism 10 to accomplish the walking process.
  • the cylinder 18 is driven by pump 128. It is advantageous to use a variable volume pump to provide relatively rapid displacement of the cylinder 18 under low load conditions and a relatively large pressure output with a correspondingly smaller travel of the cylinder 18 under high load conditions.
  • the pump swash plate shaft 130 is coupled with shaft extension 132 and subsequently through tie rod 134 to control lever 136.
  • the control lever 136 is pivotally mounted to the structure of the boring unit 12. Rotation of the control lever 136 from the vertical determines the direction of flow through the pump and the magnitude of volume per cycle.
  • resistance arm 138 can be swung into interference with the control lever 136.
  • the resistance arm 138 is pivotally mounted to the-structure of the boring unit 12 and has a plate 140 which extends into the path of the control lever 136.
  • a notch 142 is provided on the plate 140 to catch and retain the control lever 136 as it travels toward the neutral position when an excessive resistance is encountered by the pump 128. Because the plate 140 partially extends into the path of the lever 136, it provides frictional resistance to relative movement between the control lever 136 and the structure of the boring unit 12.
  • the overall operation of the unit is provided by positioning lever 116 so that block 104 is in the horizontal position. With block 104 in this position, the dogs 72 are free to rotate only as shown in FIG. 5. 'With the dogs 72 locked in the first set of slots 20, the cylinder 18 is expanded. The expansion of the cylinder 18 causes the earth boring unit 12 to advance along the rails 16. When the cylinder 18 has reached full extension, the hydraulic flow through the pump 128 is reversed and the cylinder 18 contracts. Because of the relative weight of the boring unit 12 as compared to the advancement mechanism 10, the advancement mechanism is pulled toward the unit 12. As the advancement mechanism 10 is drawn toward the unit 12, the dogs 72 rotate from the slots and slide along the rails 16.
  • the lever 116 When the operator desires to alternately advance and retract the unit 12 through a short distance, the lever 116 is positioned vertically to bring blocks 104 and 106 into simultaneous interference with dogs 72. With the lever 116 in the vertical position, the dogs 72 are unable to rotate in either direction and the advancement mechanism 10 is consequently held fixed relative to the rails 16.
  • interference arm 138 is rotated from the path of the control lever 136. in this location, the control lever 136 is free to oscillate and automatically reverse the travel of the cylinder 18 at each end of its stroke. Because this feature is only available when the pump is only partially loaded, it can only be used for retraction of the unit 12 or advancement of the unit 12 until the auger 14 encounters the earth.
  • the advancement mechanism 10 is capable of operation with a single setting of the control lever 116 and does not require a separate unlocking operation for each cycle of the walking motion. Once the direction of travel is determined through the operation of lever 116, the total walking operation is controlled by control lever 136. Further, the walking operation may be totally automated under certain circumstances as noted above.
  • the advancement mechanism further comprises means for driving said base, said driving means including a hydraulic cylinder operably fixed to said advancement mechanism and to the horizontal earth boring machine, a variable volume pump hydraulically connected to said cylinder, and means for controlling the volume and the direction of flow of said pump.
  • said control means comprises a lever arm of sufficient mass to carry by its momentum said variable volume pump into a reversed flow mode when said cylinder reaches each end of its stroke. 5.
  • An advancement mechanism for horizontal earth boring machines supported on rails and comprising a base positioned on the rails and capable of being moved along the rails in first and second directions, rigid members pivotally mounted to said base and extending to the rails, slots provided on the rails for receiving said rigid members for engaging said rigid members with the rails, said slots allowing pivotal movement of said rigid members into and out of engagement with the when in engagement with said slots, means for driving said base including a hydraulic cylinder operably fixed to said advancement mecha-- nism to the horizontal earth boring machine, a variable volume pump hydraulically connected to said cylinder, and means for controlling the volume and direction of flow of said pump.
