Definitions

  • a soil excavator includes a framework supporting a tubular boom for universal motion, a shovel being rotatably and extensibly carried on the free end of a nest of telescoped tubes lodged in the boom.
  • the framework may be anchored to a concrete shell introduced into the tunnel wall behind an advancing cutter shield.
  • the disintegration tool In machines known heretofore for the excavation and handling of soil in the case of subterranean and shield-advancing installations, the disintegration tool generally performs a rotary cutting movement. These rotating and cutting tools, however, ensure satisfactory work only in fine earth, free from stones. If such machines are worked in stony, variable and damp earthwork, their capacity falls rapidly, so that it is preferable to excavate by hand.
  • the invention has for its object the provision of means for the rational disintegration and handling of any kind of soil.
  • the shaft or stem of an excavating shovel is rotatably and longitudinally displaceably carried in a boom or jib which is suspended by a universal joint and capable of swinging to any side by means of servomotors.
  • the shaft or stem of the excavating shovel works together with a servomotor for its advance, as well as together with another servomotor for deviating or tipping the excavating shovel about an axis extending transversely to the direction of excavation, while between jib and shovel stem there is arranged a motor-driven gear by means of which the excavating shovel and stem can be transposed in turning about the stem axis.
  • the jib of the excavating device is preferably arranged on an undercarriage which is equipped with a conveyor belt for carrying off the removed soil, a chute being fitted on the front end of the conveyor belt.
  • the framework carrying the extensible and cmnidirectionally swingable shovel is disposed behind an advancing tubular cutter shield, this framework being advantageously fitted with rollers, as well as with anchoring elements by means of which the device can be immobilized in a concrete tube thrust into the tunnel in the wake of the advancing cutter.

  • FIG. 6 illustrates various shovel settings as seen from the advance-cutter in the direction of the arrow B of FIG. 4.
  • reference numeral 1 designates the undercarriage of the integrating or removing device provided with inclined bottom rollers 2.
  • the undercarriage has built thereon two pairs of vertically adjustable supporting columns 3 and 4 interconnected by a yoke.
  • This yoke (FIG. 3) comprises a fixed axle 5 having two upper rollers 6 rotatably carried thereon.
  • Axle 5 serves at the same time as a support for a journal hearing or swivel mount wherein a fork 8 is rotatably centered on a vertical axis 9.
  • Reference numeral 10 designates a tubular boom or jib which, by means of axle-pins 11 engaging the arms of fork 8, is swingable about a horizontal axis 12. Together with the horizontal bearing pins 11, the vertical bearing 7 forms a car- I danic suspension for the jib 10.
  • a pair of hydraulic cylinders 13 are disposed in the horizontal midplane of the jib at opposite sides of the cutter being attached at one end to the jib l0 and at the other end to the supporting columns 3 by means of bolts 14 and 15.
  • Numeral 16 marks another hydraulic cylinder which is arranged above the jib 10, being universally jointed at one end at 17 to the jib and at the other end by means of a cross-link 18 to bearing 7.
  • Inthe bearings 19 and 19' two square tubes 20 and 21 are rotatably carried and telescoped inside the other. These two telescoped tubes together form the stem or shaft of an excavating shovel 23 swingable around a transverse axis 22 at the front-end of the tubular part 21.
  • the interior of tubular part'21 accommodates a hydraulic cylinder 24 for advancingthe excavating shovel or scoop 23.
  • the piston rod 25 of hydraulic cylinder 24 presses against a stop 26 rigid with the inner tubular part 21.
  • An eye 27 of said stop has pivoted thereto another hydraulic cylinder 28 for the tipping and swinging of the excavating shovel 3.
  • a gear 29 is fitted and connected with, say, an electric motor.
  • the shovel stem 20, 21 can be set in rotation.
  • the two pairs of columns 3 and 4 are vertically adjustable and are interconnected by a bar 30.
  • the columns 3, 4 have fitted therein hydraulic cylinders 31 whose piston rods project upwardly, terminating in tips 32. These tips are designed for anchoring the shovel support to a surrounding shell (FIG. 3) lining the inside of the excavated gallery.
  • Other anchoring elements 33 are arranged on the longitudinal members of the under carriage frame.
  • Numerals 34 and 35 designate the operators posts from which it is possible to control not only the movement of the undercarriage but also the advance and all swivel movements of the excavating shovel.
  • conveyor-belt supports 38 and 39 Attached to the undercarriage 1, at the front at 36 and at the rear at 37, are conveyor-belt supports 38 and 39 carrying supporting rollers 40 for guiding the conveyor belt 41.
  • Reference characters 42 and 43 denote deflecting rollers arranged at the outer ends of belt supports 36, 37, the rear roller 43 being designed as a tightening roller.
  • Theconveyor-belt supports 38 and 39 also carry supporting rollers 44 for the conveyor belt 41.
  • a chute 45 is set underneath the excavating shovel 23 at the forward end of the front support 38, and guard plates 46'are disposed on the longitudinal sides thereof.
  • the rear conveyor-belt support 38 carries a hydraulic aggregate 47 which serves at the same time as an undercarriage and is fitted with two wheels 48 and an electric motor 49 for the hydraulic pump.
  • the aforedescribed device is designed as a so-called tube excavator, being associated for this purpose with a steel shield 50- which has a cutting edge and facilitates the advance of the extensi
  • the described tubular excavator depending on its size, may be inserted into tubes or galleries of, say, 1-1.5 m., 1.2-2.5 and 2.5 to 4 m. in diameter and can increase the rate of advance very considerably with a small number of workmen.
  • This tubular excavator can have a construction that is rugged and requires a minimum of attendance.
  • the excavator shovel detachable and interchangeable with a cutting head or boring tool.
  • the device may advantageously be fitted with a rope-winch for hauling the trucks in and out, or with a tubing locator. It is also conceivable to employ the jib with the universally swivelable excavating shovel in conjunction with other supporting bases and without the conveyor-belt equipment.
  • numeral 10 again designates the tube-shaped jib, and numerals 20 and stem or shaft of the excavating shovel 23, which is hinged to rotatable at the front end of the tubular. part 21 for rotation about the transverse axis 22.
  • Elements 23, 45 and 50 also have the same function as in FIGS. 1-3.

  • the lug 51 is directly anchored to the upper portion 54 of the surrounding lining tube 55.
  • the jib 10 is raised, lowered and moved laterally by means of two hydraulic cylinders 56 extending obliquely sideways, with a rearward and downward inclination, while being articulated at one end to the jib by a universal joint.
  • these hydraulic cylinders are universally jointed to cylinder pedestals 57 anchored direct to outer tube 55.
  • the anchoring of the pedestals and the lug 51 is effected by screws 58 (FIG. 5) adapted to engage threaded bushings 59.
  • these bushings In the manufacture of the concrete tube 55, these bushings firmly welded to the reinforcement skeleton of the tube.
  • the difference of the radii between tube and supporting lug and/or pedestal is equalized by inserting shims, i.e. segments of hardwood.
  • the jib along with shaft 20, 21 and shovel 23 can be both raised and lowered, and also swung towards either side.
  • the piston rods 60 of the hydraulic cylinders 56 are uniformly drawn out, and for lowering the jib they are drawn in.
  • the lateral moving of the jib 10 is effected by drawing out the piston-rod of one hydraulic cylinder, while simultaneously drawing in the piston-rod of the other cylinder.
  • the excavator according to the second form of embodiment has the advantage that the concrete tube which is normally not utilized can be made to serve as a machine part so as to ensure optimum utilization of space.
