Definitions

  • a mine-laying carriage is held stationary with respect to the ground by displacement on the vehicle at a speed equal and opposite to the speed of advance thereof, the carriage mounting a tool in the form of a curved casing constituting a means for introducing the mines into the ground, which is pivoted about a horizontal axis of the carriage, a pusher of the same curvature also pivoted about this axis, and means for effecting the working stroke and return of the tool and for maintaining each mine in its buried position on withdrawal of the tooL Patented Dec. 14, 1971 3,626,804
  • the invention relates to mine-laying apparatus and in particular to mine-laying apparatus which can be mounted on a special vehicle to constitute equipment for laying mines at high speed, continuously, and on the move, with optimum concealment.
  • the mine is introduced into the earth tangentially, without disturbing the ground and the surface layer is maintained in place to ensure concealment.
  • the mine-laying apparatus is relatively stationary with respect to the ground and is moved with respect to the vehicle at a velocity opposite to that with which the vehicle advances, so as to be relatively stationary with respect to the ground because of the opposite movement.
  • the equipment comprises two essential parts:
  • a mobile carriage comprising the mine-laying apparatus proper
  • a rocking beam pivoted on the vehicle and comprising two parallel rails, on which the carriage moves, essentially horizontal and able to be tilted so as to regulate the orientation vertically.
  • the movable carriage can be constructed in any suitable way for example of two cross-braced plates, and carriers rollers permitting movement on a roller track which is preferably mounted on the longitudinal axis of the supporting vehicle.
  • the carriage On the carriage are assembled the elements necessary for laying the mines. It mounts a support for a casing of curved section carried by arms oscillating about a horizontal axis of the carriage; the cross section of the interior of the casing permits the passage in a flat position of the mine, which is ad mitted through a feeding flap pivoted on the casing and delivered by a pivoted ejection flap forming its bevelled lower extremity.
  • This mine is pushed down the curved passage of the casing by a pusher having the same curvature as the casing, and carried by an oscillating arm which is joumaled about the same axis.
  • the arm is provided with an abutment face for a driving roller and carries a scraping tool.
  • a sector-shaped lever is pivoted on a horizontal axis parallel to the previously mentioned axis on the carriage. This lever is moved by a double-acting hydraulic ram, and controls the casing by an intermediate set of crank arms, and the arm of the pusher by a roller mounted at its end.
  • the carriage is connected to at least one sensing wheel movable in and out of operation by a double-acting hydraulic cylinder.
  • FIGS. 1 and 2 are perspective schematic views of the vehicle and mine-laying apparatus respectively before and during operation;
  • FIG. 3 is a schematic side view of the apparatus in the rest position.
  • FIGS. 4, 5, 6, 7 and 8 are views of the apparatus similar to that of FIG. 3 showing it in successive positions assumed during a cycle of operations.
  • a movable carriage 1 comprising for example two crossbraced sideplates 30 and 31, carries all the apparatus necessary to mine laying at a stationary position and can thus be used alone by stopping the supporting vehicle. It is here furnished with four rollers 2 by which it can travel on rails. It comprises the following elements:
  • a principal tool 3 constituted by a casing of the shape of a section of an arc of a circle, movable around a horizontal axle 4 passing through the center of this circle. and of which the interior cross section permits the passage of a mine to a flat position.
  • the casing has on its external surface an inlet or feeding flap or shutter 5 pivoted about an axis 28, and at its bevelled or chamfered lower end 32 an ejection flap 6 likewise pivoted about an axle 29.
  • the upper end of the casing 3 is connected to the end of an arm 7 which can oscillate about the axle 4.
  • a pusher 8 of the same curvature as the casing is arranged for movement in the interior thereof and mounts at its lower end an arrangement 9 for arming the mine 26.
  • the upper end of the pusher is connected with the end of an arm 10 which is likewise pivoted about the axle 4 and which comprises an abutment face 11.
  • a scraper 12 is fixed to the arm 10.
  • a generally sector-shaped lever 13 can oscillate about a horizontal axle 14 on the casing parallel to the axle 4 being driven by a double-acting hydraulic ram 15.
  • the lever is connected to the arm 7 indirectly by means of two crank arms 16 and carries at its end a flexible roller 17 for engagement with the abutment face 11 of the arm 10 of the pusher 8.
  • a sensing wheel I8 mounted at the end of a swinging arm 19 is controlled by a small hydraulic cylinder or jack 20.
  • the carriage I by means of its rollers 2, moves between two rails which together constitute a beam 21 pivotable about a horizontal axis fixed with respect to the vehicle, this movement being controlled by the action on its free end 27 of a stabilizing cylinder 23', this cylinder 23 is fed by means of a servovalve 24 (FIG. 4) controlled by an electric current varied by the oil pressure in the cylinder 20 controlling the sensing wheel 18 of the carriage I.
  • a servovalve 24 (FIG. 4) controlled by an electric current varied by the oil pressure in the cylinder 20 controlling the sensing wheel 18 of the carriage I.
  • This beam is mounted for example along the longitudinal axis of the support vehicle 33 between the housings 34 and the caterpillar tracks 35 (FIGS. I and 2).
  • the feeding of the mines is efi'ected through a fixed channel 25 issuing from a distribution arrangement for the mines.
  • FIG. 3 Position during transit The beam 21 is held level by the cylinder 23 (assisted if required by a mechanical lock device not shown), the correction system for vertical positioning being out of circuit.
  • the carriage l is in the forward position, the sensing wheel I8 is raised by the cylinder 20, and the flap 5 has not received a mine.
  • FIG. 4 Beginning the minelaying cycle.
  • the position is the same as the position during transit except that the sensing wheel I8 has been lowered into contact with the ground by the cylinder 20 and the vertical orientation correcting system is in action; its function is described in paragraph (g).
  • the piston of the hydraulic cylinder 15 is in the withdrawn position, the tool 3 and the pusher 8 are maintained in the raised position by the lever 13 through the crank arm I6 and the roller I7.
  • a mine 26 is fed on to the flap 5 from the supply channel 25.
  • the carriage l is in effect stationary with respect to the ground because of the backward movement on the beam 21 of the moving vehicle in the direction of the arrow F.
  • the cylinder 51 is energized and causes the lever 13 to tilt thereby driving the arm 7 of the tool 3 by means of the crank anns I6. the function of which is to ensure, by a suitable kinetic arrangement, a progressive moving off of the tool assembly (and its progressive return to its upper position at the end of the cycle).
  • FIG. 6 Lower position
  • the piston of the hydraulic cylinder is at the end of its movement and an automatic arrangement (not shown) ensures the commencement of a reverse movement without any delay interval.
  • the mine is then in its final horizontal position, the pusher 8 locking itself in its lowest position so as to prevent return movement of the mine.
  • the flap 5 remains closed due to the presence of the earth on its upper part which has the form ofa skid.
  • the carriage l finally reaches the rear end of its path, the tool 3 and pusher 8 returning to their initial positions.
  • the whole assembly then returns to the initial position of FIG. 4 by reverse movement of the carriage on the beam 21 by operation of the hydraulic jack l5 and the cycle can then recommence.
  • the beam 21 is pivotally mounted on the chassis about the horizontal axle 22 and its movement is controlled by a hydraulic cylinder 23, the piston of which acts on its free end 27.
  • the operator can actuate the hydraulic cylinder which engages the sensing wheel 18 with the ground,
  • the energization of the double-acting cylinder 23 is controlled by the servovalve 24 operated by the pressure in the cylinder 20 which is hydraulically locked in a position which effectively determines the depth at which the mines are buried. If, as a consequence of the movement of the vehicle, the beam 21 tends to rise, the wheel 18 is less firmly supported by the ground so that the pressure in the cylinder 20 decreases and this change affects by means of the servovalve 24 the supply of hydraulic medium to the lesser side of the cylinder 23 which corrects the movement.
  • This servosystem thus assures that a constant predetermined pressure is maintained in the cylinder 20 and thereby vigorously maintains the distance of the carriage above the ground whatever the movement of the vehicle, this being so not only during mine laying but during the return to action.
  • the stabilizing system is effected by a vertical movement of the rollers with respect to the carriage under. control of the pressure in the hydraulic cylinder 20.
