Definitions

  • ABSTRACT A portable earth boring machine for the horizontal boring of shafts and the insertion of pipeline casing sections in installations where excavation from the surface is undesirable.
  • the machine is characterized by a main frame portion that supports the auger drive and easing pusher apparatus, and a detachably mounted engine frame portion that permits the trans mission of power between the engine and the auger drive and casing pusher apparatus not only when the engine frame portion is positioned on the main frame portion at the boring location but also when said engine frame portion is detached and positioned at a location remote from the main frame means.
  • the machine is further characterized by a novel remote electric control means for the auger drive apparatus that provides for remote operation and hydraulically actu ated variable speed control of the boring auger at a location remote from the machine.
  • This invention relates to portable earth boring machines and more particularly to a machine adapted for horizontal boring of shafts for the insertion of pipelines at installations where excavation from the surface is undesirable.
  • the machine of the present invention comprises a base means that includes spaced track members which are disposed in a trench adjacent the hill to be bored.
  • the machine further includes a frame means mounted for movement along the track means and such frame means supports a power train for rotating con neeted sections of auger shafts which comprise a progressively extendable boring auger.
  • the frame means further supports a pusher ring for driving sections of casings into the bored hole and an associated pushing cylinder means is provided for advancing the retracting the frame means and pusher ring along the track means.

  • such circuits include valve mechanisms 44 and 46 which actuate the pushing cylinders I32 and 134 so as to extend or retract carriage 24 forwardly or rcardly along the track means 22.
  • the boring machine further includes a pusher ring 50 including a front annular surface 52'forengaging the sections of pipe casing for pushing such sections into the bored hole.
  • Such pusher ring 50 includes a thrust plate 60 mounted on the earriage means with such thrust plate 51 serving as a mount for a thrust bearing, not illustrated, for the auger connecting shaft 64.
  • the mechanism comprising the thrust plate 60, the thrust bearing assembly mounted thereon, and the back-up plates 90 transmit the thrust from the auger connecting shaft 64 to the carriage .machine of. the present invention is disclosed and de- .scribed in detail in the application of Albert R.

  • FIG. 3 is a diagram:
  • pressurized hydraulic fluid is-delivered from pump 100 via pressurized lines 126 and 146 to motor 140 and returned to the pump via lines 144 and 128.
  • the variable displacement pump 100 is reversed and thenflow through the closed Ioopcircuity is in the opposite direction.
  • Pump control-valve 116 is a normally closed three-position ,valvc which when actuated by arm 204 from centered to right or lcftpositions functions, to deliver pressurizedoil either to one side of servo motor l l yia lines 133 and l08 or to the other side via lines 133 and ,l 10.
  • Thespool of valve, 1 16 is normally biased to its center position by springs 206 and 208.
  • FIGS...3 and-1 which apparatus comprises a servo actuator l 18, that includes an electric motor 202 mounted at.valvc ll6 which merelyfunctions to move valvearm.204 between the above mentioned centercd'l'orncutral position. and right and left valve positions.
  • the remote controlapparatus further includes a remote electric controller 120, FIGS. 1, 2. and 2A which is normally removably mounted on a control console-121.
  • FIG. I thcfremote electric controller 120 is removed from console 121 andcarried about by Il'lC operator as seen in FIG. 1.
  • Thefunction of remote electric controller 120 is to op-. crate. the previously mentioned electric motor 202 in scrvoactuator 118 and the controller 120 and actuator 118 are-connected together by wires 119 as" seen-iii FIG. .1.

  • a resistor 212 which serves to varythe resistance. More particularly, when'dial "is tuincd froma 0 'or center position .inone direction by theoperator. then the current in the armature of motor 202 in. servoactuator 118 is varied soas to drive the spool'of pump control valve 116 from right'Yposition. Similarly. when dial knob 125 is turned from its center position in the other direction electric motor202 in servo actuator 118 moves the spool'in pump .control valve from its center. position to its"fleft position,
  • I -Valve; 116 then delivers pressurized fluid to servo control 101. of variable pump 100 and the wobble plate of the pump is-fnoved in a conventional manner to cause the delivery of pressurizedfluid to drive motor 140 in the forward direction. It will now be seen that the more dial 125 is. rotated from 0 to the left, the faster motor 140 will rotate in a forward direction.
  • FIG. 2 andFlG. 2-A when dial 125, FIG. 2 andFlG. 2-A is rotated from 0 to right, then movable contact 210 is driven to-the right witharesulting change in potential in the armatureof motor 202. Valve actuating arm 204 is moved progressively to the right whcrebypump 100 and motor 140 are driven in thereverse direction.
  • dial knob 125 of controller 120 permits the operator to set-the pump control servomotor I01 atan infinite number of settings within its range from zero to maximum. Hence the settings for flow output from pump 100 and hence the directional rotational speed of motor 140 and the boring auger driven thereby are infinitely variable within the establishcdrange from zero to maximum rotational speed.
  • fixed pump 102 further serves .to charge the previously mentioned closed loop circuit via'lincs and check valves 129 and 127. Whcnoneof the check valves 129 or 127 is on the pressure side of the closed loop then it will be biased closed and hence oil from line 130 can only be released from the opposite one of the check valves 129 or 127 to the low pressure side of the closed .loop.
  • a pressure relief valve 122 is provided in line 130 for releasing excess fluid delivery from fixed pump 102 back to tank.
  • a pilot operated shuttle valve 152 which includes the pressure actuated pilots 154 and 156 is provided to prevent the build-up of excess pressure within the housing of motor 140 due to the occurrence of leakage and high pressure air around the pistons of the pump.
  • Pilot operated shuttle valve 152 is shifted upon occurrence of high pressure on the high pressure side of the closed loop circuit so as to open the low pressure side of the closed loop circuit to a surge. flow relief valve 158.
  • pilot 154 shifts shuttle valve 152 so as to expose the other side of the circuit, the low pressure side, to surge flow relief valve 158 thereby protecting the low pressure side of the pump'motor circuit from any excessive surge pressures which may occur.
  • the fluid lines 126., 128, and 172 are extended through the remote control loom 161, along with the wires 119 which connect remote electric controller 120 with the servo actuator 118 as previously described. Also the fluid lines 126,
