Definitions

  • the present invention relates to a complete demining system designed primarily for clearing mines in open land including undulating land to liberate the land from both buried and unburied mines of both the anti-personnel type as well as large area defence and anti-tank mines.
  • the requirement for the demining system in accordance with the present invention to clear both buried and unburied mines means that it must be able to penetrate ground layers down to the greatest depth at which it can be expected to find active mines, while the requirement to be able to demine undulating terrain means that the device that actually performs the demining operation must be able to be inclined in relation to the carrier vehicle. Moreover, the device must be driven by a powerful force through the ground layers since it not only needs to cope with mines but also with vegetation in the form of roots, bushes, small trees and small stones that may be present. The complete demining system must thus be extremely ruggedly constructed and have an extremely large engine at its disposal.
  • the demining system cannot be dimensioned for the largest mine that could possibly be found but rather for those mines that can be expected to be most common.
  • the demining device must therefore be so designed that in the event of damage occurring from an extremely powerful mine detonation the device is easy to repair. We believe that the demining system in accordance with this invention meets all these requirements.
  • the demining system in accordance with this invention thus comprises a carrier vehicle with a motor-driven demining device rotating around a mainly horizontal axle mounted in front that operates in the ground ahead of the vehicle.
  • a motor-driven demining device rotating around a mainly horizontal axle mounted in front that operates in the ground ahead of the vehicle.
  • An appropriate alternative would be a chassis from an old main battle tank or armoured combat vehicle.
  • This device is constructed as a disc cultivator comprising a number of cultivator discs mounted parallel to each other on one and the same cylindrical shaft, the outer periphery of each disc being fitted with teeth.
  • the advantage of this device is that the discs when rotated mechanically by a great force have an exceptionally good capability to penetrate ground layers down to a sufficient depth for the purpose intended while crushing and demolishing the mines that are in its path.
  • the intention is thus that the mines in the first instance shall be demolished without detonating, but should they happen to detonate the disc cultivator device is so open that the main part of the explosive force is directed outwards away from the cultivator discs of the device. Should damage be inflicted on the device such damage will be limited and easily repairable since the cultivator discs are constructed in the form of easily separable sectors.
  • the present invention relates in the first instance to the mounting of the device and to the interconnected parts that together enable the actual demining device to be inclined to a sufficient degree to enable it to function in undulating terrain.
  • the shaft of the demining device is mounted at each end in a beam extending in the longitudinal axis of the vehicle and these two beams have a common pivoting point of ball coupling type in the vicinity of the centre of gravity of the complete demining system, and the angle of these beams relative to the vehicle and thereby also relative to the ground surface is determined by hydraulic cylinders located between the beams and the vehicle, each hydraulic cylinder being between the common pivoting point and the device.
  • This arrangement enables the shaft of the device to be inclined relative to the vehicle while simultaneously the working depth of the demining device in the ground is determined by the setting of each of the beams.
  • a traverse steering unit that enables the beams to be raised and lowered and the shaft to be inclined but which prevents lateral motion.
  • This traverse steering unit comprises a cross-beam that interconnects the mounting points of the shaft of the device, and a guide-way located laterally on this cross- beam in which guide-way a pivotable pivot block is engaged.
  • the pivot block is so designed that it allows the necessary inclining of the cross-beam and thereby also of the shaft of the demining device.
  • both beams are located along the longitudinal sides of the carrier vehicle and the beams are interconnected by a pivotable main beam extending across the vehicle and mounted on the common pivoting point of the two longitudinal beams.
  • the main beam also houses the drive motor for the demining device and one of the longitudinal beams may be utilised to encapsulate the transmission that is necessary between this drive motor and the actual demining device.
  • Figure 1 shows an oblique projection of the complete demining system.
  • Figure 2 shows a side section of the same system.
  • Figure 3 shows a more detailed section of the beam arrangement incorporated with the drive for the device indicated together with the traverse steering unit whose task is to assimilate the lateral load forces on the demining device.
  • Figure 4 shows a section through the actual demining device and its mounting points.
  • the vehicle shown in the various figures is a main battle tank chassis 1 supplemented with a fragment-protected operator's cabin 2.
  • a main beam 3 is located across the vehicle 1.
  • the ventilation apertures shown in Figure 1 indicate that the main beam 3 houses the motor that drives the actual demining device 4. This is only indicated in Figure 1.
  • the main beam is mounted on an extremely robust ball coupling 5 that enables both tilting in the longitudinal axis of the vehicle as well as inclination in the lateral axis of the vehicle 1.
  • Two beams 6 and 7 extend from the main beam 3 along the longitudinal axis of the vehicle and the front end of these beams support the device carrier 8 and the actual demining device 4.
  • the setting of the beams 6 and 7 relative to the vehicle 1 and thereby also relative to the ground surface is determined by two adjacent demining device mounts located between the beams and the hydraulic cylinders 9 and 10 located on the vehicle.
  • the hydraulic cylinders 9 and 10 can be set individually which means that the complete rigid system comprising the main beam 3, beams 6 and 7, the demining device carrier 8, and the demining device 4 can be inclined relative to the vehicle for deployment on inclined ground surfaces such as slopes and the sides of ditches. In the same way the cutting depth of the demining device 4 into the ground can be regulated.
  • the drive motor located in main beam 3 for driving the demining device is connected to a belt drive 11 located mainly in beam 7 and comprising the drive pulley 12 and the transfer pulley 13.
  • a second belt drive 14 is engaged to enable the couplings 15 and 16 (see also Figure 4) that connect the beams with the demining device carrier 8 to be employed.
  • Figure 3 also shows the traverse steering unit whose task is to assimilate the lateral forces acting in a longitudinal direction on the demining device 4.
  • the traverse steering unit is comprised of two traverse steering plates 18 and 19 connected to the cross-beam 17 incorporated in the demining device carrier 8. Only traverse steering plate 19 is visible in Figure 3 together with the pivotable pivot block 20 attached to the vehicle and engaged between the two traverse steering plates 18 and 19.
  • the actual demining device carrier 8 incorporates as previously stated a cross ⁇ beam 17 that interconnects both bearings 21 and 22 for the actual demining device consisting of roller 23 equipped with a large number of fixed circular cultivator discs 24 that are each comprised of easily replaceable segments.
  • the outer periphery of each cultivator disc is fitted with a number of teeth 25 of the type shown in Figure 2.
  • the actual demining device can rotate in the direction of drive of the vehicle 1 and can also counter-rotate.
  • the teeth 25 are thus always angled so that it is their points that impact first with the ground.
  • the task of the teeth 25 is to mill to destruction everything that comes in their path — primarily mines.
  • Figure 4 shows a detailed illustration of the transfer between the two belt drives 11 and 14.
  • Figure 2 shows the actual demining device in the mode utilised for deployment in the ground at maximum depth and rotating counter to the direction of drive of the carrier vehicle 1.
  • the demining device 4 can also rotate in the opposite direction, i.e. in the direction of drive of the vehicle, in which case the direction of the teeth 25 shall be reversed.
  • Figure 4 also shows a hydraulic reduction gear 26 incorporated into the roller 23 to reduce the revolutions of the drive motor to the desired rate of revolutions for the demining device 4.

Abstract

La présente invention concerne un système de déminage. Ce système comprend un engin de transport (1) et un dispositif de déminage (4) qui fonctionne au sol devant l'engin. Ce dispositif est entraîné par un moteur monté sur l'engin, et tourne autour d'un arbre (23) qui s'étend dans le sens transversal et essentiellement horizontal par rapport à l'engin. Le système de déminage selon l'invention a pour but de débarrasser de vastes zones ouvertes du sol, y compris les terrains en reliefs, de toutes les mines enterrées et déterrées. Pour assurer l'inclinaison nécessaire, et une puissance suffisante, du dispositif de déminage, celui-ci est entraîné par un moteur monté dans la poutre transversale de l'engin, raccordant les deux poutres longitudinales. La totalité du châssis peut alors être latéralement inclinée et basculée par rapport au véhicule (1) via un dispositif d'accouplement à rotules (5) fixé à proximité du centre de gravité de l'engin, tandis que les forces latérales agissant sur le dispositif de déminage sont assimilées par un ensemble de direction transversal distinct (18-20) fixé entre le dispositif de déminage et l'engin.
