CONSTITUTION: Each of molded explosive cartridges 10 contained in each of through- holes 1a is pressed and contact-bonded to a desired drilling position by a method wherein each of the molded explosive cartridges 10 is placed in each of the through- holes 1a of a drum 1c of molded explosive cartridges containing means 1, and then a moving platform 6 is moved to be set to a specified position in the front of a specified position of a structure 9, and ejection means operates. The drum 1c is rotated by specified degrees by operating a driving source of the molded high-explosive cartridges containing means 1, and each of the explosive cartridges 10 for a next through-hole 1a is opposed to the ejection means 7, and then the moving platform 6 is moved to the front of a next specified position, and each of the explosive cartridges 10 for the next through-hole is contact-bonded to a specified position as described above. Afterwards these operations are orderly repeated to contact-bond each of the high-explosive cartridges 10 to each of specified positions of the structure 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Field of Application The present invention is used for drilling holes in concrete, spring break, metal, etc., especially for drilling holes in walls and foundation concrete of reactor containment vessels and buildings. This invention relates to an automatic loading device for shaped explosive cylinders.

(2) Conventional technology Conventionally, when drilling holes in concrete etc. using a molded explosive canister, after drilling several mounting bolt holes with a hole drill etc. at the position where the molded explosive canister is to be attached to the object, Each piece was installed by hand.

(3) Problems to be solved by the invention However, since the molded explosive cylinder is attached by one person after drilling the mounting bolt hole, efficiency is low, and the precision of the hole position is poor, making it difficult to install the shaped explosive cylinder in close proximity. It is difficult to drill holes,
Particularly, work in an atmosphere containing radiation such as in a nuclear reactor has drawbacks such as being extremely dangerous from a safety standpoint.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide an automatic loading device for shaped explosive cartridges that can safely, quickly and automatically drill accurate holes in sequence at each desired drilling position. .

(4) Means for Solving the Problems In order to achieve the above object, the present invention has a drum which is rotatable by a driving source and has a number of through holes radially arranged on the same radius to accommodate shaped explosive cylinders. It is characterized by comprising a shaped explosive cylinder storage means, an ejection means that advances and retreats with respect to the through hole of the drum on the rear surface of the drum and presses and injects the 1& type explosive cylinder forward, and a moving platform on which these means are installed. .

(5) Operation After loading the molded explosive cartridges into each through hole of the drum of the molded explosive cartridge storage means, move the moving table and set it at a predetermined position in front of a predetermined part of the structure, and actuate the injection means. , presses the shaped explosive cartridge stored in the through hole to crimp the shaped explosive cartridge at the desired drilling position.

Next, the drive source of the shaped explosive cartridge storage means is activated to rotate the drum by a certain angle to bring the next through-hole shaped explosive cartridge to face the injection means, and then move the moving platform to the front of the next predetermined location. In the same manner as described above, the through-hole molded explosive cartridge according to the method described above is crimped to the predetermined location.

Thereafter, these operations are repeated to successively press-bond the molded explosive cylinders to each predetermined location of the structure.

(6) Examples Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

(1) indicates a shaped explosive cylinder storage means;
is a large number of through holes (la) at equal intervals on the same radius...(1
It consists of a drum (IC) that rotates at a constant angle (for example, 45°) by a drive source (1b) that has a drive motor (rp1 not shown) and has a built-in drive motor (rp1 not shown), and (2) is concentric with the drum (1). A drive source (2b) having at least one circular hole (2a) in a portion facing the through-hole (1a) and a built-in drive motor (not shown) is operated at a certain angle (for example, 180°).
A rotating tray-shaped protective disk is shown, and the protective disk (2) is firmly supported and fixed to the movable table (6) together with the drum (lc) by the shaft (3) and support members (4) and (5). has been done.

(7) indicates an injection means consisting of a cylinder, and the cylinder (7) moves a built-in rod (7a) forward and backward by hydraulic or pneumatic pressure, and also moves a through hole (l) of the drum (IC).
It is fixed to the movable table (6) concentrically opposite to a).

(8) indicates a sensor, such as a microswitch, provided at the end of the moving platform (6), and the microswitch (
8) is a structure such as a carp, a creel, a wall (9) and a moving platform (
6) The distance between the two is now detected.

(10) indicates a molded explosive cylinder, and the explosive cylinder (10) is, for example, as shown in Fig. 3, a cylindrical cylinder made of paper or synthetic resin or the like is attached to the tip of a holder (10a,) in the form of a cylinder with a lid made of synthetic resin or the like. A conical metal bottom plate (10c) is supported at the bottom of the frame (10b).
), and the inside is filled with gunpowder such as black gunpowder or explosives such as dynamite (10d), and the holder (
Adhesive (FOE) is applied to the root end of the LOA.

Note that (10f) indicates the detonator section.

(11) indicates a movable arm, the arm (11) is placed on a moving vehicle (12), etc., and is configured to be freely movable by a cylinder (lla);
The movable table (6) is provided at the tip.

Thus 1. For example, the concrete wall of the reactor containment vessel (9)
When drilling a hole in a concrete wall (
9), move the arm (11) to move the moving table (6) forward, and press the micro switch (8).
) to maintain a predetermined distance between the moving table (6) and the concrete wall (9). And drilling position and drum (1)
The through hole (1a) at the lowest position and the circular hole (2a) in the disc (2)
, and the cylinder (7) on the same center line and actuate the cylinder (7).
) moves forward, presses and injects the molded explosive cylinder (10) built into the through hole (1a), and the adhesive (10e) applied to the end hits the wall (9). The explosive cylinder (lO) is adhesively fixed to the wall (9) as shown by the solid line in FIG.

After that, the rod (7a) is moved back, and then the drum (IC) is rotated 45 degrees to bring the next through hole (la) to the lowest position, and the moving platform (6) is moved back, allowing the movement of the moving vehicle (12). By moving the arm (11), the through hole (la) is made to face the next drilling position, and the explosive cylinder (10) in the through hole (la) is adhesively fixed to the concrete wall (9) in the same manner as described above. .

In this way, the explosive cylinder (10) is converted into concrete 1! (
When the gunpowder or explosive (10d) explodes by igniting the detonator part (10f) of these explosive cylinders (10), the bottom plate (1) of the frame body (10b)
0c) is bent into a conical mountain shape, so the shock wave caused by its explosion is concentrated at the desired hole position.

As a result, holes can be drilled in the concrete wall (9). In this way, drilling at predetermined intervals can be performed automatically.

(7) Effects of the Invention According to the present invention, a rotatable drum is provided with a large number of through holes to house shaped explosive cartridges, and the injection means sequentially injects the molded explosive cylinders from the through holes onto the wall surface. After bonding, these explosive cylinders are detonated to drill holes in concrete, etc., so there is little dust generated during drilling, and even when used in places where there is danger of contamination by radiation, etc. The handling of drilling equipment is safe, holes can be drilled quickly and automatically at accurate drilling positions, and the construction period can be shortened, which has many effects.
