Definitions

  • the present invention relates to a machine for mole ploughing, i.e. simultaneous ploughing up a ditch and laying a flexible cable or conduit in it, the machine including a vehicle, a plough connected to the vehicle and guide means mounted oil the plough for advancing the conduit into the ditch from a rotatably mounted storage reel while the vehicle is advanced along the ditch.
  • the machine is preferably used for electrical and telephone cables, but may also be used for other purposes such as laying water hoses.
  • a machine is known, from the Norwegian Patent Specification 136 586 for example, comprising a tractor excavator with a plough connected to its excavating bucket, the plough having guide means for the cable.
  • a cable reel is attached to the front blade of the excavator.
  • Such a machine is burdened with a plurality of disadvantages.
  • One disadvantage is that the machine will be encumbered with equipment which is heavy to lift and which is voluminous.
  • Another disadvantage is that the equipment hinders the use of the machine for other purposes, such as other excavation work in conjunction with the removal of boulders and stumps and in connection with landscaping work.
  • a further dis ⁇ advantage is that the rotational resistance of the cable reel and other friction forces in the equipment will be so large that the cable is stretched, and thus does not follow the contour of the ditch bottom, resulting in that the cable does not obtain a constant laying depth and can be subjected to impermissibly large stresses and exterior damage.
  • Patent Specification 3 486 334 teaches a road grader, to which is connected a plough and guide means for a cable, the latter being wound off from a reel carried by the grader for laying in the ditch made by the plough.
  • This road grader has the disadvantages mentioned above with regard to space requirements, use for other purposes as well as stresses on, and damage to the cable.
  • a hand-operated cable layer connectable to a vehicle and provided with plough and guide means for the cable is known from the U.S. Patent Specification 3 066 491.
  • the cable is fed by a drive means down into the ditch made by the plough at a somewhat greater speed than the vehicle travelling speed.
  • Disadvantages with this cable layer are that it cannot be connected to the arm or bucket of a mechanical excavator, that it does not carry any cable reel, and that no regula ⁇ tion of the feed speed is possible, which means that an unnecessary excess of cable or a deficient amount of cable, possibly causing damage thereto, is fed into the ditch. Disclosure of Invention
  • One object of the present invention is to improve the known machines of the kind described above and to provide a machine, which primarily allows it to be utilised as an excavator without extensive assembly and dismantling work and also for laying cable without the latter being subjected to impermissibly large stresses, either during laying or after the ditch has been filled.
  • Figure 1 is a schematic side view of a machine in accordance with an embodiment of the invention.
  • Figure 2 is a view seen from behind of the macnine according to Figure 1 , and substantially along the line II - II in Figure 1.
  • Figure 3 is a schematic side view of another embodiment of a part of a machine in accordance with the invention.
  • the ground surface is denoted by M in Figure 1
  • D denotes a ditch excavated with the aid of the inventive machine and in which a cable K is laid with the aid of this machine.
  • a suitable excavator for the purpose may be that of the type illustrated in the U.S. Patent Specification 4 297 799.
  • a unit 1 is removeably attached to the bucket G by the gripping means R gripping round a bar 2 included in the unit, while a shoe 3 on the unit accomodates the bucket teeth.
  • the unit 1 otherwise comprises a plough 4, a cable guide means 5 attached to the rear of the plough, and a carriage 6 pivotably mounted to the plough.
  • the plough 4 is directed forwards in the mole ploughing direction illustrated by an arrow in Figure 1 , and at its rear portion it is limitedly sw ⁇ ngably mounted at 7 in a frame 8 included in the carriage 6.
  • Two posts 9 and 10 are welded to the frame 8, as well as two arms 11.
  • Two wheels 12 are rotatably mounted on the frame 8 at mutual spacing, which exceeds the maximum width of the plough 4.
  • a shaft Ra is rotatably and removably mounted on the upper ends of the arms 11.
  • a shaft 13 is rotatabl mounted at the upper ends of both posts 9 and 10.
  • a belt pulley 14 attached to the shaft 13 is driven by a belt 15, which in turn is driven by a belt pulley 17 attached to a wheel axle 16 connecting the wheels 12.
  • a second belt pulley 18 is attached to the shaft 13.
  • a guide collar 19 is suitably pivotably mounted on the post 9.
  • a cable leader 20 provided with an eyelet is pivotably mounted on the post 9, on which a gas spring 21 is also pivotably mounted, the piston rod end of the spring being pivotably attached to the cable leader 20.
  • the unit 1 is first connected to the bucket G by the bucket being maneouvered by the machinist so that its teeth are inserted in the shoe 3 and the bar 2 comes into engagement against the back of the bucket.
  • the machinist then swings the arms A, which were previously moved apart, towards each other for gripping the bar.
  • the bucket G is then moved upwards and is swung clockwise in Figure 1 so that the arms 11 will be substantially horizontal, after which these are moved in under the shaft Ra of the cable reel R.
  • the unit 1 and thus the arms 11 are now lifted so that the shaft Ra is placed in the cradles 11a at the upper ends of the arms 11 in Figure 1.
  • the unit is then swung anti-clockwise so that it assumes the position illustrated in Figure 1, with the wheels 12 on either side of the ditch D which is to be ploughed.
  • the plough 4 forms the ditch D simultaneously as the cable K wound up on the cable reel R is fed out to the bottom of the ditch via the details mounted on the posts 9 and 10 together with the guide means 5 which includes a pipe stub 5a and a curved duct 5b. If the pull in the cable K does not attain a given limiting value when the cable is fed out, the cable will lie on the bottom of the ditch D and follow its contour.
  • the cable is fed from the reel R via the guide collar 19 and through the eyelet of the cable leader 20, which is urged upwards in Figure 1 by the spring 21 , this position of the leader being illustrated by chain- dotted lines in Figure 1 , whereon the cable is at a distance from the rotating belt pulley 18, and further through the guide means 5 and out to the ditch.
  • the cable leader 20 will be affected if the pull on the cable increases for some reason so that it attains a predetermined limiting value, which partly depends on the bias in the spring 21 and partly on the friction forces acting on the reel R and cable K as the cable is fed out to the ditch.
  • the cable leader 20 will be swung anti-clockwise to the position illustrated by full lines in Figure 1 against the bias of the spring 21 by the action of the tensioned cable during continued advance of the vehicle, the cable coming into engagement with the rotating belt pulley 18, which then feeds the cable with a speed somewhat exceeding the normal cable lay- ing speed. This results in that the pull in the cable decreases, the cable slackening off and accompanying the contour of the ditch bottom.
  • the cable leader is swung clock- wise in Figure 1 by the bias of the spring 21 and moves the cable out of engagement with the belt pulley so that the cable will then be wound from the reel without being driven by the belt pulley 18.
  • the cable leader 20 will thus move the cable in and out of engagement with the belt pulley during cable lay ⁇ ing in response to the pull in the cable.
  • the machinist moves the unit 1 to a suitable position in the already excavated ditch, or to one side thereof, whereupon he releases the unit 1 from the bucket G by swinging the arms A away from each other and thereafter withdrawing the bucket teeth from the shoe 3.
  • Figure 3 Since the embodiment in Figure 3 only differs from the one in Figure 1 in respect of the drive means for the cable, only the parts of the machine according to the -modified embodiment which relates to the drive means and co-acting details are illustrated in Figure 3. Remaining details are identical with those illustrated in Figure 1 , excepting that the carriage 6 is not only swingably connected to the plough 4 but also removably connected to it at 7. The details in Figure 3 which have their counterpart in Figure 1 have been denoted by-the same reference numerals with the addition of a prim sign.
  • a pipe 30 extending up over the belt pulley 18' is attached to the post 9'.
  • a gas spring 31 Inside the pipe 30 there is a gas spring 31, the lower part of which is pivotably attached to the lower end of the pipe.
  • a roller 32 At the upper end of the gas spring 31 there are a roller 32 and one end of an arm 33 mounted for turning.
  • the other end of the arm 33 is pivotably connected to a bell crank 34, which is pivotably mounted on the outside of the pipe 30 and provided with a handle 34a.
  • the roller 32 bears against the underside of the right hand portion of a guide arm 35, the left hand portion of which is provided with a fork-like end portion 35a.
  • the guide arm 35 is pivotably mounted on the pipe 30 at 36, and a conical rubber wheel 37 is rotatably mounted on the guide arm between 35a and 36.
