Abstract

PROBLEM TO BE SOLVED: To improve efficiency of breaking work by providing a sheet laid on a breaking object forming an installing hole, a pushing-in means having a pushing-in body and a filling member for filling a transfer substance in the sheet. SOLUTION: A winding motor 4 is arranged to move a winding sheet 5 along a surface of a breaking object 2, and a filling nozzle 11 for delivering a transfer substance 8 is arranged so as to be freely liftable. A moving distance detecting sensor 20 is arranged to detect a position of a tip part of the filling nozzle 11, and a control device 21 is arranged to control driving of the winding motor 4 according to this position detecting signal. Thus, Since the transfer substance 8 is filled in an inserting sheet 9 pushed in an installing hole 3 by pushing the inserting sheet 9 into the installing hole 3 of the breaking object 2 by the filling nozzle 11, clearance is not generated between the inserting sheet and the installing hole 3 to thereby reduce labor such as filling the clearance between the inserting sheet 9 and the installing hole 3 with a filling substance to improve efficiency of breaking work of the breaking object 2.

[0004]

In the conventional breaking device described above, in order to sufficiently transmit the expansion force accompanying the melting and vaporization of the thin metal wire 30 to the object to be broken, there is no gap between the breaking container 26 and the mounting hole. It is necessary to. However, the diameter of the mounting hole depends on the situation at the site and depending on the means for drilling the mounting hole, and the diameter in the depth direction of the hole is not constant. It is not always possible to ensure that there is no gap between them. Therefore, by forming the diameter of the mounting hole larger than the breaking container 26 in advance, the breaking container 26 can be easily inserted into the mounting hole. However, forming the mounting hole with a diameter larger than necessary increases the working time.

If a gap is formed between the destruction container 26 and the mounting hole, the expansion force when the thin metal wire 30 is melted and vaporized is not sufficiently transmitted to the object to be destroyed as described above. Therefore, it is necessary to fill the gap between the destruction container 26 and the mounting hole with a filler for filling the gap. Therefore, an object of the present invention is to provide a destruction device and a destruction method that can solve the above-mentioned problems.

And an apparatus.

Further, when the thin metal wire 6 is melted and vaporized, a transmitting material 8 (water or jelly is used) for transmitting the expansion force of the thin metal wire 6 to the peripheral surface of the mounting hole 3 by a phenomenon accompanying the melting and vaporization. ), A filling nozzle (filling member) 11 having a filling hole 10 formed therein for filling the transmitting material 8 into the insertion sheet 9 of the rolled sheet 5 pushed into the mounting hole 3, On the other hand, a pushing means 12 for pushing the filling nozzle 11 and the electrode 7 together with the insertion sheet 9 is provided.

The pushing means 12 is provided with the filling nozzle 1.
1 has a pusher 13 attached to the base end thereof, and a jack device 14 for moving the pusher 13 along the mounting hole 3. The pushing body 13 and the electrode 7 are inserted through the lid member 15. The filling hole 1
0 is formed at a predetermined position from the lid member 15 to the tip.

The push body 13 includes an elbow tube 16.
The elbow pipe 16 is connected to a supply pipe 17 for supplying the transmitting substance 8 to the filling nozzle 11.
A transmission substance supply device 18 is connected to the supply pipe 17, and a pressure detection sensor 19 for detecting the supply pressure of the transmission substance 8 is connected in the middle of the supply pipe 17. Further, the jack device 14 is connected to a movement amount detection sensor 20 for detecting the movement amount of the push body 13, and the push body 13 is pulled out of the mounting hole 3 on the output side of the movement amount sensor 20.

Next, a destruction method using the destruction device 1 will be described. When the object to be destroyed 2 is destroyed or weakened, a mounting hole 3 is formed at a predetermined position of the object to be destroyed 2.
Then, the wound sheet 5 is laid at a position facing the mounting hole 3, while the push body 13 and the electrode 7 are
And the electrodes 7 are electrically connected to each other by the thin metal wires 6.

Then, the jack device 14 is arranged at a position facing the mounting hole 3, and the jack device 14 is extended.
Then, the insertion sheet 9 starts to be inserted into the mounting hole 3 at the tip of the filling nozzle 11. Here, as shown in FIG. 3, when the electrode 7 and the filling nozzle 11 are almost completely pushed into the mounting hole 3, the transmitter 18 is driven. Then, the transmitting substance 8 is supplied from the filling hole 10 of the filling nozzle 11.
Starts to be filled into the insertion sheet 9.

Thereafter, the electrodes 7 are electrically connected to each other by the thin metal wires 6,
In the same operation as described above, the abrupt expansion force of the thin metal wire 6 is applied to the object 2 to destroy the object 2.

When another mounting hole 3 is formed at a different position, the entire destruction device 1 (excluding, for example, the power supply device) is moved toward the other mounting hole 3, and the same destruction method as described above is performed. Destroys the object 2 to be destroyed. Thus, according to the embodiment of the present invention, the winding motor 4 for moving the wound sheet 5 along the surface of the object 2 to be destroyed is provided, and the filling nozzle 11 for discharging the transmitting substance 8 is connected to the jack device 14.

Since the insertion sheet 9 pushed into the inside is filled, a gap is prevented from being generated between the insertion sheet 9 (transmitting substance 8) and the mounting hole 3 regardless of the diameter of the mounting hole 3, and the insertion sheet 9 is not filled. Filling material between mounting hole 3 In no trouble such filling, it is possible to improve the efficiency of destruction operations of the debris 2.

In the above embodiment, the surface of the object to be destroyed 2 is described as being horizontal in the method of destroying the object to be destroyed 2, but the invention is not limited to this. That is, the present invention can be applied to a case where the surface of the object 2 is vertical. Further, in the above-described embodiment, the thin metal wire 6 is used as the molten vaporized material. However, the present invention is not limited to this.
