Description

Minor damage Demining machine Technical field

The present invention is designed to allow a person to step on a landmine buried area evenly with greater force than a person can walk, exploding all detonating mines on the spot, and thereby allowing a person to safely enter the landmine area. It relates to demining machines. Background art

More than 110 million landmines are buried worldwide, with 24,000 people killed or injured annually. Moreover, landmine removal is said to be only 100,000 a year, which is a major problem worldwide. _

Land mines include iron, blast, wood, bamboo, and paper.The blasting fuse of the detonator is 1 to 10 kg for anti-personnel mines, and 10 to 200 for anti-tank mines. It is 0 kg. The detonation method includes pressure, pressure release, change in wire tension, and proximity of electromagnetic waves from detectors. Some high-grade land mines are detonated by magnetism, sound waves, electromagnetic waves, heat, and so on. The amount of explosives is about 50 to 20 kg for anti-personnel mines and about 4 to 10 kg for anti-tank mines. For example, in Cambodia, 99.9% are small anti-personnel mines, have a diameter of 78 mm, a total weight of 140 _g , an explosive capacity of about 51 _g , are pressure-initiated, and are metal Some of them pop out.

The removal of this type of land mines has become an urgent task worldwide, but the removal work has many difficult conditions and is not yet mechanized. For this reason, at present, mine mines are searched for using metal rods or metal detectors called They excavate them with care and then treat them by blasting. However, there is a problem that the above metal detector is inefficient because it reacts to nails and the like. Also, some of the mines discovered are explosive when dug up, which is dangerous. For military use, various removal machines have been created to break through minefields rapidly, but the purpose is to remove them quickly, with the intention that even if there are some leftovers, they can be expensive. Because of its design, it cannot be used for demining in peace. Government agencies in Cambodia have requested a 99.6% removal rate.

The present invention has been made in view of the above circumstances, and aims to provide a device capable of safely and reliably removing land mines so that a person can safely step into a land mine zone. It is assumed that. Guidance of invention

The mine clearance machine of the present invention is characterized in that it comprises a pressing member for detonating the ground by depressing the ground and detonating the mine, and a traveling vehicle for moving the pressing member along the ground. The details are as follows.

First, a demining machine according to a first aspect of the present invention includes a pad for pressing the ground, a stem mounted on an upper portion of the pad to support the pad, and a vertical movement of the stem connected to the stem. And a driving device that moves the rod up and down to utilize the energy of the fall, and a traveling trolley that supports the driving device. are doing.

The mine eliminator according to the first aspect of the present invention uses a pad to sequentially press the ground with the use of the weight of the mouth component while running the mine zone with a trolley. If there is a land mine, it will explode when the pad is pressed, so that people can step on with confidence. Pads, stems, etc. due to landmine explosions These parts are broken, but these are consumables, and if broken, they can be replaced with new ones.

A demining machine according to a second aspect of the present invention is a demining machine comprising: a plurality of pads for shaking the ground; a tapping stem for supporting the pads and the nodes; and a plurality of hydraulic pressures for applying a pressing force to the plurality of pads. A traveling cylinder including: a cylinder; an original cylinder that distributes and supplies hydraulic pressure to the plurality of hydraulic cylinders; and a pressurizing device that pressurizes the original cylinder to generate hydraulic pressure. It is specially equipped. As the pressurizing device, a hitting device used for crushing rocks, a vibrating device, a road compacting device, and the like can be used.

This demining machine distributes not only gravity but also the impact force of the pressurizing device to press the ground with the pad, so that sufficient pressure can be reliably applied.

The pad should be a deformable water bag, or the joint between the stem and the pad should be a spherical joint so that the pad can apply force uniformly regardless of the unevenness of the ground. (Keep it fastened with a string.) It is preferable to support it with a free joint or a rubber shaft so that it can tilt freely.

In addition, if a plurality of rod components composed of a node, a stem, a rod, and the like are arranged in parallel, and these components are driven up and down while being shifted in phase from each other, a large number of components can be obtained. This is preferable because the bogie is more stable and the drive unit can be made smaller than when the load components are simultaneously moved up and down.

Next, in the mine eliminator according to the third invention, a roller component having a pair of front and rear rollers as a pressing member is provided in front of a bogie traveling on the ground so as to be vertically movable, and It is characterized in that a weight and a pressure device are provided at the front and rear middle part of the roller component to apply force and energy to the front and rear rollers.

In the front part, when a plurality of the above-mentioned component aggregates G are juxtaposed, the adjacent aggregates are connected to each other. Left and right set so as not to interfere Partition plates 50,... Located between the bodies are provided in parallel. In the case where only one set of the aggregate G is provided, such a guide frame is not necessarily required, but it is preferable to provide the guide frame even for positioning the lower part of the aggregate. In addition, it is preferable to attach a boulder (not shown) and a wire hooking fork (not shown) for detonating a mine of a burnt wire type at the front end of the guide frame 45. . These shapes and the like are not particularly limited. Needless to say, the number of α-components included in the rod component aggregate G and the number of the aggregates can be appropriately increased or decreased according to use conditions and the like.

The tapping pad 40 and a television camera 55 for monitoring the ground and the like are provided at the front end of the bogie. The video signal captured by the camera 55 is used for remote control.

When the component assembly G is attached to them and vertically moved in synchronization with each other, In order to maintain the balance of the bogie, it is preferable that the vertical movements of the lift arms be shifted from each other in order to maintain the balance of the bogie. This makes it possible to reduce the output of the hydraulic motor 19 of the driving device. It is preferable to sequentially delay a plurality of lift arms and move them up and down. However, it is not always necessary to shift the vertical timing of each lift arm. The operation timing may be shifted in three groups.

In the illustrated example, a cam-type driving device is used as the vertical driving device D of the lift 13 supporting the rod component H. Since the energy of the component falling is used, other appropriate mechanisms such as a mechanism for moving the hydraulic cylinder up and down by expanding and contracting it can be used. In some cases, it is also possible to adopt a mechanism in which the lift is fixed, an eccentric rotating portion is provided at the tip of the arm, and the arm is moved up and down by eccentric movement. -Next, Figs. 5 (a), (b), and (c) show examples of a method of supporting a tubing pad different from the above, and this pad 40 is a two-shaft universal joint J2. It is attached to the lower end of the tubing stem 35 through the tubing stem 35. That is, the lower end of the stem 35 and the intermediate bead S 1 of the joint J 2 are pivotally connected by the first shaft 62, and the intermediate bead 61 and the bus 65 are connected to the second shaft 6. It is pivoted by 6. Since the two axes 62.S6 are orthogonal to each other, the pad 40 can be freely tilted back and forth and left and right according to the unevenness of the ground. The point that a flexible sheet 41 made of rubber or the like is provided below the pad 40 is the same as in the above embodiment.

Downward projections 65 a and 65 a are provided at both ends of the bar 65, respectively, and the lower end of the projection forms a spherical surface and is formed in the spherical concave portion 40 a of the pad 40.

The hydraulic pressure distributor 135 is composed of a single original cylinder 1336 and a plurality (1S in the illustrated example) of small cylinders (liquids) provided below the original cylinder 13S. Pressure cylinder) 1 3 7,… X 2

And the original cylinder and each of the small cylinders are connected by a hydraulic passage 13. 1336a in the figure is the toner of the original cylinder 1336. The rod 130a of the punching machine 130 hits the cylinder, and the cylinder 130b is blown. The liquid L inside becomes high pressure.

The hitting machine 13 ◦ is a pressurizing device ^ for generating pressure in the original cylinder 13 36, and the pressurizing device is a pressurizing device S as shown in the illustrated example. In addition, a known vibration device, a road surface compaction device, or the like may be provided.

The small cylinders 13 7 below the former cylinder 13 36 are provided side by side as many as the number of pads that press the ground, and the inside of the cylinder is the inner diameter of the former cylinder. The liquid is smaller and is stored in the upper space of piston 1337a. The hydraulic distributor 135 has a Tsubbing'Tem support frame 1338 attached by a bolt. The support frame 1338 is made of a plastic material such as vinyl chloride and has a tubing stem described later.

Each stem is inserted into a through hole of a holding plate 13a provided at a lower portion thereof in order to prevent buckling of 140.

When the piston of the original cylinder 1336 is hit by the hitting machine 1330, the hydraulic pressure is distributed and supplied to each of the small cylinders 1337 through the hydraulic pressure flow path 1339. The piston 1337a of the small cylinder is pressed downward. The piston rod 1337b is connected to the piston 1337a of the small cylinder, and the lower end of the piston rod is connected to the tapping stem 140. A rubber band (or a string) hung on the upper and lower hooks 141 and 142 in a state fitted into the hole 140c provided at the upper end is supported so as not to fall off.

The lower end 140 a of the tapping stem 14 ◦ is attached to a tapping pad 144 via a biaxial universal joint J 2. This support structure is almost the same as the pad support structure of the first aspect of the present invention, and therefore details are omitted. In the present invention, the piston port 1337b of the small cylinder corresponds to the port. This, together with the evening stem 144 and the towing pad 144 constitute the mouth component (tapping component).

A pressure detection sensor is provided between the lower end of the piston rod 1337b of the small cylinder 1337 and the bottom of the hole 140c of the tapping stem 140.

Due to this impact, a high hydraulic pressure is generated in the original cylinder 1336, and this hydraulic pressure is distributed and supplied to the plurality of small cylinders 1337,.

First, when the tubing device is lowered and grounded, each tubing pad 145 is grounded, and then the distributed hydraulic pressure causes-each tubing pad to press the ground. If landmines are installed on the traveling route of the bogie, this tapping ensures that the detonation is performed. When the land mine explodes, the tabbing sheet 151, the tabbing pad 144, the tabbing stem 140, etc., which constitute the tabbing component (load component) H ', are removed. They will be damaged, but they are consumables and should be replaced with new ones.

In the above description, a hydraulic striker (breaker) is used as the primary pressure generating device S for pressing the primary cylinder, but in some cases, a pneumatic striker may be used. However, other suitable pressurizing devices that can generate the required amount of source pressure can also be employed. In addition, the number of tapping pads in one component aggregate G ′ is, for example, 4 × 4 = 1S, but it is needless to say that this number can also be reduced appropriately. Nor.

Providing impact and energy ensures a sufficient amount of stepping and ensures that mines can be detonated. If the tire part of the roller is configured as a water-filled tube as shown in the illustration, the impactor is effectively transmitted to the ground.

In the event of an explosion, the roller 2 17 and arm plate 2 13 are blown off by the shear bin 2 15, and there is little damage to the removal machine itself or the bogie. Moreover, there is an advantage that consumable parts are inexpensive and can be easily replaced.

Landmines are predominantly anti-personnel mines with a drug dose of 50 to 100 gr, but with the blast, the outer shell is scattered and has the ability to kill people. Also, unexploded bombs may explode, and in the unlikely event that an anti-tank mine may be detonated, human safety should be considered first. It is desirable to use a remote control type equipped with a monitoring camera, periscope, back mirror, etc., respectively.

Industrial applicability

The demining machine according to the present invention is manufactured industrially in the same manner as a normal industrial machine, and uses a pressing member such as a tapping pad or a roller to exert a force greater than that of a person stepping on it. Pressing the depressions without gaps will explode all landmines exploding on the spot, so that people can enter safely. In addition, there is an advantage in turning the former site into farmland.
