Description

The utility model relates primarily to mining and can be used to eliminate freezes.

There is a known vibration method and device for eliminating freezes and arching of bulk materials in containers (R.A. Zenkov, G.P. Grinevich, V.I. Isaev. Bunker devices. Moscow, "Mechanical Engineering", 1977, p. 91), in which vibrations are transmitted to the walls of the container, and through them to the thickness of the material.

The disadvantage of this method and devices is the impossibility of their effective application to eliminate freezes in underground conditions.

A known method of cleaning containers from hanging and sticking (RF patent No. 2093785, publ. 20.10.1997). The essence of the invention: in the cavity of the cleaned container place the tank. Through the pipeline it is filled with the estimated volume of the gaseous explosive mixture. The same pipeline initiates a gaseous explosive mixture. The tank can be destructible, indestructible. It can be formed by installing an additional movable lining in the form of a sheet coating.

The disadvantage of this device is the danger and the impossibility of their effective use to eliminate freezes in underground conditions.

A device for eliminating freezing of rock mass in ore passages (RF patent No. 2233981, publ. 10.08.2004). The device contains a board with a powder installation for launching a cumulative grenade. The powder launcher is mounted by means of a swivel joint at the end of the board, suspended upside down on the brackets with guide rollers to the roof, suitable for the horizontal run of the mine. Positioning the launching device in the ore pass, launching the grenade and removing the device before the collapse is carried out remotely using a pulley with pulleys, latches and cords.

The disadvantage of this device is the structural complexity of manufacturing and low accuracy.

A device for the elimination of freezes in coal-blast furnaces and ore passes (RF patent No. 2131040, publ. 05.27.1999). The inventive contains a guide tube, a propelling charge and a pipe mounting mechanism, in which two rupture discs are installed at its ends and two pistons are connected connected by a destructible rigid connection, between which the propelling charge is located, while the missile element is made with a flat head part and profiled bottom and placed in the upper part of the pipe, resting its bottom against the bursting disc, and in the volume between the membranes and pistons placed liquid, such as water.

The disadvantage of this device is the structural complexity of manufacturing and low accuracy.

A device for explosive elimination of freezes in vertical and inclined rock runs (RF patent No. 11830, publ. 16.11.1999), adopted as a prototype. The device for contains a housing filled with explosive, and a delivery system to the detonation point, according to the invention, the housing is made in the form of two chambers (main and auxiliary), located one after the other and separated by a blank partition, two holes are made in the front camera, one hole is made in the front end of the housing for loading explosive, closed by a screw plug, and another hole is made in the side wall, in which the detonator is installed with the ignition cord attached to it, in the rear end housing in the bottom of the second chamber, an opening in the form of hard hose-shank, around which the nozzle-hole on the hose end of the shank-reinforced pnevmomuftoy connection to air hose from the compressed air source or an air-water mixture.

The disadvantage of this device is the structural complexity of manufacturing and low accuracy.

The technical result of the claimed invention is to simplify the design, as well as improving the accuracy of the hit.

The technical result is achieved by the fact that in the device for explosive elimination of freezes containing a housing made in the form of one after the other main and auxiliary chambers filled with explosive, moreover, in the auxiliary chamber there is a hole with an ignition cord attached to it, closed by a stopper, according to the invention the main chamber is made in the form of a cylinder with spherical bases, and the working side of the main chamber is made in the form of a sphere concave inward with a tight fit the surface of the steel spherical plate, and in the auxiliary chamber, located without a partition from the main chamber, an intermediate detonator is installed on the convex part with the ignition cord removed from it for attaching initiation means to it, while a centralizer is provided in the central part of the steel spherical plate for magnetically fixing the laser pointer .

The device for eliminating freezes is illustrated by the drawings, where in FIG. 1 shows a vertical section of the device, where:

1 - the main chamber of the body, filled with explosives, made in the form of a cylinder with spherical bases, for example, from aluminum;

2 - the working side of the main camera 1 of the housing;

3 - steel spherical plate, tightly adjacent to the working side 2 of the main chamber 1;

4 - auxiliary camera, rigidly fixed without a partition on the main camera 1 on its convex non-working side 10;

5 - an intermediate detonator installed in the auxiliary chamber 4;

6 - ignition cord, for example, a detonating cord, derived from the intermediate detonator 5;

7 - means of initiation, for example, an electric detonator;

8 - centralizer for magnetic fastening of the laser pointer, rigidly fixed in the Central part of the steel spherical plate 3;

9 - laser pointer magnetically mounted on the centralizer 8;

10 - convex non-working side of the main camera 1.

A device for eliminating freezes, contains the main chamber 1 of the housing, made in the form of a cylinder with spherical bases, for example of aluminum, filled with explosive. On the concave side of one of the spherical bases of the main camera 1, the working side 2 of the main camera 1 of the housing is made. The magnitude of sphericity (focal length) is determined by experimental, experimental-analytical or analytical methods. On the working side 2, a steel spherical plate 3 is fixed rigidly adjacent to the working side 2 of the main chamber 1. The auxiliary chamber 4 is filled with explosives and is rigidly fixed without a partition on the main chamber 1. An intermediate detonator 5 is installed in the auxiliary chamber 4. From the intermediate detonator 5 the ignition cord 6 is removed, for example, a detonating cord. The length of the ignition cord 6 should be sufficient to securely fasten the means of initiation 7, for example, an electric detonator. A centralizer 8 for magnetically securing the laser pointer is rigidly fixed in the central part of the steel spherical plate 3. A laser pointer 9 is magnetically fixed on the centralizer 8. When transporting to the auxiliary chamber 4, it is recommended to wear a protective plug (not shown conditionally) to prevent damage to the ignition cord 6.

A device for eliminating freezes works as follows. The assembly of the device is delivered to the place of use in a box (not shown conditionally) in compliance with safety precautions when handling explosives. Determine the installation location of the device with the organization of the base of bulk material, for example, sawdust. The device is removed and the laser pointer 9 is magnetically mounted on the centralizer 8 and turned on. Next, they lay the device on bulk material, after which they direct a beam from the laser pointer 8 to the object to be destroyed, for example, hovering. After pointing, the laser pointer 9 is removed, turned off and removed for subsequent use. Then, initiating means 7, for example, an electronic detonator with an electrical tape, are carefully fixed on the ignition cord 6. Depart to a safe distance and explode the means of initiation 7. The means of initiation transmits a pulse through the ignition cord 6 to the intermediate detonator 5, which in turn initiates explosive in the main chamber of the housing 1. Explosive energy, in accordance with the theory of cumulative charges, causes separation and folding of a steel spherical plate 3 with its movement towards the destructible object. When a steel spherical plate 3 collides, a physical effect on hovering occurs, which leads to its destruction.

The use of the device to eliminate freezes provides the following advantages:

design simplification;

improved hit accuracy;

device cost reduction;

simplified installation operations;

increase work safety.
