Description

  The present invention relates to an anti-personnel mine destroyer for blasting buried anti-personnel mines with a hammer's striking force to form a safe zone free of mines.

  Landmines are buried extensively in conflict areas around the world, and many people are damaged by buried landmines. The removal of buried landmines is a global emergency.

  However, conventional landmine removal work is manual. For example, mines are searched for with metal detectors, carefully excavated, and then processed by blasting. However, the metal detector has a problem that it is inefficient because it reacts with nails and the like. Also, some mines that are discovered are dangerous because they can explode when they are dug up, which is a very dangerous task.

  Therefore, many attempts have been made to mechanize the removal of buried landmines. For example, as shown in Patent Document 1, a heavy-duty vehicle with a rotary cutter type landmine disposal device is proposed. This method digs the ground with a rotary cutter type landmine treatment device and blows up antipersonnel landmines buried under the ground surface, but the device is large, expensive, and procured easily in developing countries. There is a problem that it is difficult.

In addition, as disclosed in Patent Document 2, a landmine destroyer that blasts a landmine by hitting the ground and impacting the landmine has been proposed. This landmine destroyer cannot be said to correspond to the unevenness of the ground, and there is a problem that it is insufficient for removing the landmine buried in the concave portion of the ground.

  Hereinafter, although the embodiment of the anti-personnel landmine destroyer of this invention is described, this invention is not limited to the following embodiment.

  FIG. 1 is a side view showing an embodiment of an antipersonnel landmine destroyer according to the present invention. The present invention will be described mainly with reference to FIG. The antipersonnel landmine destroyer 1 of the present invention has a structure in which an antipersonnel landmine destruction device 3 is attached to a traveling vehicle 2. The traveling vehicle 2 comprises a pair of left and right independent endless track vehicles 21 connected by a vehicle frame 22 to form one vehicle. Each of the pair of left and right endless track vehicles 21 includes an endless track 23, and a driving sprocket 24 at the upper front end of the endless track vehicle 21 drives the endless track 23 of each vehicle. , 252, 253, 254. A roller receiver 26 is provided to prevent the endless track 23 from hanging down between the upper sprockets 24 and 254.

  A saddle frame 4 that constitutes the antipersonnel mine destruction apparatus 3 is provided on a vehicle frame 22 that connects the left and right endless track vehicles 21. The saddle frame 4 has a floor frame 41 attached to the vehicle frame 22. A plurality of support frames 42 and a beam frame 43 spanned between the support frames 42 are combined in a bowl shape at the front portion of the floor frame 41. The support frame 42 is separated in the middle, and is joined by a sleeve 44 and assembled. This takes into account that the transport height in trucks can be halved by disassembling in the middle. A flat ceiling frame 45 is provided at the upper end of the eaves frame 4 so as to project in the direction of the eaves toward the front in the horizontal direction and project also in the rear.

  The floor frame 41 is provided with a generator 5 that supplies electricity to the entire apparatus. Further, the floor frame 41 is provided with a traveling motor 51 powered by the generator 5 in each of the left and right endless track vehicles 21, and the traveling sprocket 24 of the traveling vehicle 2 is driven by the chain 52 to travel the traveling vehicle 2. Can be made. Since the left and right endless track vehicles 21 are driven independently, the traveling vehicle 2 can be turned freely by driving each endless track vehicle 21 independently.

  As shown in FIGS. 1 and 2, a pair of upper and lower support frames 46 protrude from the both ends of the front surface of the saddle frame 4 in the front horizontal direction, and the upper support frame 46 has a plate-like upper hammer guide 61. A plate-like lower hammer guide 61 is attached to the lower support frame 46. The hammer guide 61 is separated from the dredge frame 4 by the support frame 46 so that the influence of the mine explosion does not easily reach the dredge frame 4.

  As shown in FIG. 3, the rectangular plate-shaped hammer guide 61 is formed with hammer guide holes 62 for passing a total of 30 hammers 71 in three rows of 10 in the front-rear direction in this embodiment. The positions of the respective hammer guide holes 62 of the guide 61 coincide with the vertical direction. A sliding material 63 such as polyimide (nylon) having a low friction coefficient is provided on the periphery of the hammer guide hole 62 so that the hammer 71 slides smoothly.

  As shown in FIG. 1, a total of 30 square bar-shaped hammers 71 are inserted through the hammer guide holes 62 of the two upper and lower hammer guides 61 so as to be movable up and down. The upper ends of the respective hammers 71 are connected to the start ends of the chains 72, and the ends of the chains 72 are passed through a balance weight guide 64, which is attached to the rear surface of the saddle frame 4 in a pair of upper and lower portions. The balance weight 73 is connected. The chain 72 is converted from a vertical direction to a horizontal direction by a three-stage front end pulley 65 provided at the front end portion of the ceiling frame 45, passes through a first guide 66 fixed to the upper surface of the ceiling frame 45, and passes through the ceiling frame 45. 45 passes through the chain block push-up body 81 of the hammer elevating frame 80 moving along the upper surface of 45, passes through the second guide 67 and the third guide 68 fixed to the upper surface of the ceiling frame 45, and passes the rear of the ceiling frame 45. The direction is changed from the horizontal direction to the vertical direction by a three-stage rear end pulley 69 provided at the end, and is connected to the upper end of the balance weight 73. Therefore, the hammer 71 and the balance weight 73 are suspended. In this embodiment, since the hammer guide holes 62 of the hammer guide 61 are arranged in three rows, ten chains 72 are arranged in a row, and three rows are arranged in the vertical direction.

  A first rocking body 711 that rotates about a first shaft attached to the lower end of the hammer 71 is attached to the lower end of the hammer 71, and is further orthogonal to the first axis provided on the first rocking body 711. A second rocking body 712 that rotates about a second axis of direction is attached. The first oscillating body 711 and the second oscillating body 712 functioning as a universal joint incline the second oscillating body 712 corresponding to the inclination of the ground surface, and the lower surface of the second oscillating body 712 is inclined with respect to the ground surface. You can touch the flat.

  As shown in FIGS. 4 and 5 showing the lifting mechanism 8, the chain 72 is connected by a chain bolt 721 as a stopper at the rear portion of the chain bolt push-up body 81 of the hammer lifting frame 80, and this chain bolt 721. Constitutes a part of a lifting mechanism 8 described later. A pair of left and right elastic bodies 722 such as rubber are fixed to the front surface of the chain bolt 721.

  The hammer elevating frame 80 constituting the lifting mechanism 8 is provided such that a roller 83 attached to a base 82 with the ceiling frame 45 as a rail runs so that the ceiling frame 45 can be moved forward and backward. A front end 84 projecting upward from the base 82 is provided on both sides of the front end edge of the base 82, and three, for example, groove-type steel chain block push-up bodies 81 are horizontally arranged on the rear surface of the front end 84 in the vertical direction. It is spanned in the direction and fixed. The chain block push-up body 81 is provided with a through hole (not shown) through which the chain 72 is inserted, and the chain 72 is passed through the through hole. When the hammer lifting frame 80 moves backward, the rear surface of the chain block push-up body 81 collides with the elastic body 722 of the chain bolt 721 so that all the chain bolts 721 are moved back together as the hammer lifting frame 80 moves backward. All the hammers 71 are raised. Further, a projecting body 85 projecting downward is fixed to the base 82 at the lower rear end of the hammer lifting frame 80.

  As shown in FIG. 1, a hammer lifting endless track 9 that constitutes a lifting mechanism 8 is installed below the ceiling frame 45. The endless track 9 for raising and lowering the hammer has a chain (endless track) 93 spanned between a drive sprocket 91 and a driven sprocket 92 that are spaced apart in the horizontal direction. A hammer elevating motor 94 is disposed below the drive sprocket 91, and a chain 95 is stretched around the drive shaft and the drive sprocket 91 as an endless track. A pair of roller follower mounting bases 96 are fixed to symmetrical positions of the chain 93 of the hammer lifting endless track 9, and the roller follower mounting bases 96 are attached to the roller follower mounting bases 96.

  When the hammer elevating motor 94 is driven, the upper endless track 93 travels rearward, and the roller follower 97 protrudes upward around the driven sprocket 92 along with this, and is indicated by a one-dot chain line that is moving forward as much as possible. The roller follower 97 moves rearward while pushing the protruding portion 85 as the endless track 93 travels while abutting on the protruding portion 85 of the hammer lifting / lowering frame 8 shown (see FIG. 5). When the protrusion 85 is pushed, the hammer lifting frame 80 moves rearward, and along with this, the chain block push-up body 81 of the hammer lifting frame 80 bundles all the chain blocks 721 whose positions are uneven. To move. As a result, all the hammers 71 are lifted and raised. When the roller follower 97 reaches the drive sprocket 91, the roller follower 97 descends by moving around the drive sprocket 91 as the endless track 93 moves. As a result, the engagement between the roller follower 97 and the projecting portion 85 of the hammer lifting frame 80 is released, and each hammer 71 falls free independently of the weight of the hammer 71. At that time, the chain block 721 moves forward while pushing the lifting frame 80 forward until all the hammers 71 collide with the ground surface. When unevenness exists on the ground surface, the falling position of the hammer 71, that is, the forward movement position of the chain block 721 also varies depending on the position of the hammer 71, and the hammer 71 that collides with the deepest concave portion of the ground surface among the respective hammers 71. The chain block 721 moves forward while pushing the lifting frame 80. The position where the chain block 721 moves most forward is the position indicated by the one-dot chain line where the hammer lifting frame 80 collides with the first guide 66. When the tips of some of the hammers 71 reach a flat ground surface, the distance from that point until the chain block 721 reaches the most advanced position is a distance that can correspond to the concave portion of the ground surface. Thus, since the antipersonnel landmine destroyer 1 of this embodiment makes the hammer 71 fall freely, the fall position of the hammer 71 also changes according to the unevenness | corrugation of the ground surface, and the 2nd rocking body 712 of all the hammers 71 is. Can collide with uneven ground surface, impacting landmines below the surface, and blasting.

  In the anti-personnel landmine destroyer 1 of this embodiment, the stroke that the roller follower 97 of the hammer elevating track 9 pushes the protrusion 85 of the hammer elevating frame 80, that is, the movable distance that the chain block 721 can move to the maximum is reduced. When the distance that the hammer 71 lifted to the maximum height of 1.5 m reaches the flat ground surface is about 1 m, the hammer 71 can cope with the depth of the ground surface of 50 cm at the maximum. Since the anti-personnel landmine can be sufficiently destroyed if the hammer 71 has a fall distance of about 0.8 m with respect to the convex surface of the ground surface, it can cope with at least 20 cm. As a result, the antipersonnel landmine destroyer 1 of this embodiment can destroy landmines corresponding to the unevenness of +20 cm and −50 cm on the ground surface.

  The vertical position of each hammer 71 that collides with the ground surface varies depending on the unevenness of the ground surface. Therefore, the position of the chain block 721 also varies depending on the drop position of the hammer 71, but the hammer lifting frame While 80 moves backward along with the movement of the endless track 9 for raising and lowering the hammer, the roller follower 97 continues to retreat until the roller follower 97 is separated from the projecting body 85 of the frame 80 for raising and lowering the hammer while sequentially pushing all the chain blocks 721.

  An exposure prevention plate 47 is provided on the front surface of the heel frame 4. Further, a handrail 48 is provided behind the floor frame 41, and an operation panel (not shown) for operating the antipersonnel mine destroyer as a whole is installed at the rear of the dredge frame 4. An operator can operate the antipersonnel landmine destroyer 1 by riding on the floor frame 41 and operating the operation panel.

  The weight of one hammer can be 10 to 100 kg, and the weight of one balance weight 73 can be 5 to 90 kg. The balance weight 73 is provided in order to reduce the output of the hammer lifting motor 94 by reducing the weight for lifting the hammer 71. The weight obtained by subtracting the weight of the balance weight 73 from the weight of the hammer 71 becomes the substantial weight of the hammer 71. When the substantial weight of the hammer is 10 kg, the impact energy of the hammer when the drop height is 1.0 m is about 108 J, and the detonation power of the antipersonnel mine is 1 to 10 kg. Is enough.

  For example, if the weight of the hammer 71−the weight of the balance weight 73 = about 10 kg, the output of the hammer lifting motor 94 that lifts 30 hammers at a time is sufficient at about 5.5 kW.

  Further, when the output of the two traveling motors 51 is about 2.2 kW, the antipersonnel landmine destroyer 1 of the present embodiment, which is calculated to have a total weight of about 7 tons, can travel at a speed of about 490 m / hour. Since the endless track vehicle 21 is employed, the climbing slope is about 20 °. The output of the generator 5 required to operate the traveling motor 51 and the hammer lifting / lowering motor 94 is about 15 kW.

  The operation of the antipersonnel mine destroyer 1 of this embodiment will be described. An operator riding on the rear part of the floor frame 41 starts the operation of the generator 5. Then, by operating the driving of the two right and left traveling motors 51, the traveling vehicle 2 can be advanced, rotated, and retracted. Normally, the hammer lifting / lowering motor 94 is driven while moving forward, and the hammer lifting / lowering endless track 9 is operated. If the endless track 9 for raising and lowering the hammer is rotated once in 10 seconds, the hammer 71 moves up and down once every 5 seconds. When the traveling vehicle is moved forward by about 4 m per minute, each hammer 71 is moved 12 times. The ground surface will be beaten, and antipersonnel mines below the ground surface can be blown out with the impact force of the hammer 71 without leakage. Even if the antipersonnel mine explodes, the first rocking body 711 and the second rocking body 712 at the tip of the hammer 71 are designed to withstand the explosion, and the operator is protected by an exposure plate. When operating for 8 hours a day, a safe zone free from anti-personnel mines can be formed with a width of about 1700 mm while advancing about 3900 m per day.

  Although the anti-personnel mine destroyer 1 of this embodiment employs a simple mechanism that moves the traveling vehicle 2 forward while raising and lowering the hammer 71 for destroying the anti-personnel mine, the unevenness of the ground surface is Even if it exists, the anti-personnel mine can be destroyed reliably. Further, less power is required to raise the hammer 71, the structure itself is simple, and it can be manufactured at a cost that can be used even in developing countries. Also, maintenance is easy.

  In the above description, the chain has been described as an index connecting the hammer and the balance weight, but a rope such as a wire rope may be used. Moreover, although it demonstrated that an operator boarded and operated, since there is danger in the explosion of the mine for anti-tanks, you may make it operate remotely. Further, although the traveling vehicle is described as an endless track vehicle, it may be a vehicle that travels with normal wheels. Furthermore, although the frame for raising and lowering the hammer is retracted in an endless track, other mechanisms may be adopted.

  INDUSTRIAL APPLICABILITY The antipersonnel landmine destroyer of the present invention can be used for a humanitarian application in which a buried antipersonnel landmine is destroyed to form a safe zone free of landmines.
