Description

[Detailed description of the invention] [Industrial application field] The present invention is a structure for connecting blocks constituting a minefield disposal system, specifically, a plurality of explosive blocks each having a can body loaded with explosives, and a control device in the can body. The can bodies such as equipment blocks that house the equipment are connected in series by connecting cables, and the foremost can body and the last can body are connected to the flying object and the braking means, respectively, by connecting cables. The present invention relates to the above-mentioned connection structure in a minefield processing device configured as follows.

[Conventional technology]

The above-mentioned minefield processing device was proposed earlier by the present applicant (Japanese Patent Application No. 59-8246 and Japanese Patent Application No. 59-262877).
This will be explained with reference to FIGS. 1 and 4.

FIG. 1 is an overall explanatory diagram of the mine field disposal device, and symbols .about. indicate operating stages. In the drawings, 1 is a flying object such as a rocket, 2 is a plurality of explosive blocks, 3 is an equipment block, and 4 is a parachute as a braking means.

The explosives block 2 is, for example, a short cylindrical can with a bottom and a lid, loaded with explosives and equipped with a detonator.・It stores equipment such as arm devices. Then, for example, place the equipment block at the end and these blocks 2, 2...
...and 3 as shown below, connecting rope 5
The first explosive block 2a is connected in series by a connecting cable 6, and the equipment block 3 is connected in series by a connecting cable 6.
are connected to the flying object 1 and the parachute 4 by connecting cables 7, respectively.

The device according to the above-mentioned Japanese Patent Application No. 59-8246 is mainly constructed as described above, and the blocks 2, 2, . . . and 3 are fastened together using a wire rope 8 and a latch 9.
This fastening body is housed together with the parachute 4 in the barrel 1a of the flying object 1, and a rear cover 1b is fastened to the rear end using a gunpowder-type breaking bolt or the like.

When such a flying object 1 is launched towards a minefield M, after a predetermined time has elapsed, the rear cover 1b is released by a signal from the timer and the parachute 4 is released, and the fastening body of the block is released by this parachute. At the same time, the latch 9 is released and the blocks 2, 2, . . . , 3 are separated (step). Thereafter, this connected block body is towed by the flying object 1 while being braked by the parachute 4, so that each block unfolds in a chain (stage) and in this state descends onto the minefield M (stage). . Here, each explosive block 2 is detonated upon receiving a signal from the timer, detonating the landmine.

Further, the device according to the above-mentioned Japanese Patent Application No. 59-262877 has a brake cable 10 added to the above structure, and a strong nylon rope or the like is used as the brake cable 10, and its front end is attached to the parachute connecting cable 7, for example. Pile 11 tied together and the rear end driven into the vicinity of the firing point
moored to etc.

According to this device, as shown in the step, the brake cable 10 is extended and sudden braking is applied during the descent, so that the descending position can be made more accurate and the aligned posture of the blocks can be stabilized.

FIG. 4 shows the connection structure of the equipment block 3 as an example.

In the figure, 15 is the can body, which is formed into a short cylindrical shape having a side wall 19, a front end wall 20, and a rear end wall 21 by a can body 16 and a can lid 17 fastened 18 to the can body. has been done. 22 is a hook 23 fastened to the center of the front end wall 20; 5 is the connecting cable connecting the blocks; the connecting cable 5 is, for example, a nylon string knitted into a tape shape; The terminal portion is passed through the hook 22 and attached to the hook 5a. Reference numeral 24 denotes a screw boss protruding from the center of the rear end wall 21, and the terminal 7a of the connecting cable 7 of the parachute is screwed onto this screw boss. The can body 15 houses the above-mentioned equipment.

Incidentally, the foremost explosive block 2a is this can body 15.
It has almost the same structure as the one above, and an explosive is loaded inside, and a connecting cable 6 is attached in place of the connecting cable 7. In the other explosive block 2, the screw boss 24
A hook 22 is fastened to this portion instead of forming a .

[Problem] By the way, in such a conventional connection structure,
There was a problem that the weight of the can was increased, which caused a problem that the flight performance of the projectile and the filling rate of the explosive were reduced.

The reason for this is that the tension exerted by the connecting cable acts on the central portion of the end wall of the can body, requiring the end wall to have sufficient strength, which requires the can body to be thick.

Incidentally, the tension acting on the connecting rope is approximately
1000Kgf, about 300 when towed like a stage
Kgf, or when the sudden braking is applied in a stage, is approximately 4000 Kgf, and particularly in a stage or stage, a large tension acts impulsively on the can body at or near the rear end.

Therefore, an object of the present invention is to make the can body capable of resisting the above-mentioned tension without having to make it thick.

[Means of the invention]

The means of the present invention for solving the above problem is to wrap a connecting cable from one side of the can body to the end face and then to the other side, and then tie the end portion to the connecting cable.

[Effect]

According to the above means, since the connecting cable is split into two from the binding portion and directed toward both sides of the can body, the tension mainly acts on these both sides. The can body is therefore able to resist tension as a whole.

〔Example〕

In Fig. 2, 30 is a can body of an explosive block, which is composed of a can body 31 and a can lid 32 like the conventional one, and also has side grooves 34 formed in four equal parts of the side surface 33 of the can body 30. be. 35 and 36 are can body 3
They are attached to the front end wall 37 and rear end wall 38 of 0 by means of hooks fastened to the front end wall 37 and rear end wall 38 of 0, with their orientations changed by 90 degrees. As can be seen in the rear end (on the right side of the drawing), the connecting cable 5 has a portion 5 near its front end.
A is fitted into the side groove 34 on one side of the can body 30, then passed through the hook 35 and along the front end wall 37, and then fitted into the side groove 34 on the other side and wrapped around it.
b is sutured and tied to the base body 5c of the connecting rope. The connecting cable 5 on the front side is also wrapped in the same manner using the remaining opposing side grooves 34 and hooks 36, and 5d is the above-mentioned stitched portion. The positions of these stitched portions are determined so that even if the end-side portion 5a becomes slack, the portion does not come out of the opposing side grooves 34, 34. Incidentally, the side groove serving as the pull-out prevention means can be replaced with hooks or protrusions such as the hooks 35 and 36.

FIG. 3 shows an example of the connecting structure of the parachute connecting rope 7. As shown in FIG. In the same figure, reference numeral 40 denotes a connecting metal fitting, the rear part of which has a cylindrical shape with a bottom and a female thread 41 inside, and the front part of which has a flat plate shape and is wound around both sides of this flat plate part 42 as described above. Each end of the connecting cable 5' is arranged, and furthermore, abutting plates 43, 43 are applied to both sides of the connecting cable 5', and are tied together with bolts and nuts 44. Then, the terminal 7a of the parachute connecting cable 7 is screwed onto the female thread 41. Flying object 1
The connecting rope 6 can also be connected in the same manner.

Therefore, when using the above-mentioned connection structure, the front and rear connecting cables cross each other, and their tension acts alternately from four equal parts on the circumference of the can body, exerting a bending action on the entire can body. operate However, since the can body has an extremely large section modulus due to its structure, bending stress can be kept to a minimum.

〔effect〕

As explained above, according to the present invention, even if the can body is subjected to a strong tension, it can be easily resisted, so that the can body can be made thin and its weight can be reduced.
