Description

The utility model "Oxygen Spear" refers to devices for destruction, in particular for the separation cutting of metal and concrete, mainly large-size and thick-walled structures and structures, and can be used in construction, dismantling and emergency operations, as well as in anti-terrorist operations.

The oxygen spear adopted in the description of the utility model for patent RU No. 137494 dated 02.20.2014 with a priority of April 10, 2013, IPC B23K 7/08 was adopted as a prototype.

The named oxygen spear includes a steel tube with metal, in particular with steel and aluminum, wires inside it.

Signs of a known oxygen spear, coinciding with the features of the claimed utility model, are the presence of a steel tube and metal wires inside it.

The reason that prevents obtaining a technical result in a known technical solution, which is provided by the claimed utility model, is that the technical means of the known oxygen spear do not allow the destruction of structures and structures in hard to reach and dangerous places, in particular, cutting metal and concrete structures in position “side”, in the position “around the corner” and in the position “behind the two corners”.

The task to which the claimed utility model is directed is to expand the operational capabilities of the oxygen spear.

The technical result, which provides the solution of this problem, consists in the creation of technical means to expand the operational capabilities of the oxygen spear when cutting metal and concrete structures and structures, namely to cut them not only in the position of direct (frontal) access to the places of their cutting, but also in the position of non-direct (non-frontal) access to the places of their cutting, in particular in the "side" position, in the position "around the corner" and in the position "because of two angles".

The technical result is achieved in that in an oxygen spear including a steel tube with metal wires inside it, the steel tube together with metal wires is made curved in the shape of a hook.

The implementation of a steel tube together with metal wires inside it bent in the form of a hook, firstly, with a hook bend angle of more than 0 ° and not more than 90 °, allows cutting metal and concrete structures and structures in the "side" position.

The implementation of the steel tube together with metal wires inside it is bent in the form of a hook, and secondly, with a hook bend angle of more than 90 ° and not more than 180 °, it allows cutting metal and concrete structures and structures in the “from the corner” position.

The implementation of a steel tube together with metal wires inside it bent in the form of a hook, and thirdly, with a hook bend angle of more than 180 ° and up to 270 ° and more, allows cutting metal and concrete structures and structures in the position “because of two angles” .

All three of the above-mentioned options for the hook bend angle (more than 0 ° and not more than 90 °; more than 90 ° and not more than 180 °; more than 180 ° and up to 270 ° and more) expand the operational capabilities of the oxygen spear, namely, they provide the possibility of cutting metal and concrete structures and structures in hard-to-reach or inaccessible or dangerous places for a person-carver, namely, in the positions "side", "around the corner" and "because of two angles".

New features of the claimed technical solution are that in the oxygen spear, which includes a steel tube with metal wires inside it, the steel tube together with metal wires is made curved in the shape of a hook,

while as an option:

firstly, the angle of the hook is more than 0 ° and not more than 90 °;

secondly, the angle of the hook is more than 90 ° and not more than 180 °;

thirdly, the hook bend angle is more than 180 ° and up to 270 ° and more.

The utility model is illustrated by drawings (Fig. 1-4), which represent the claimed oxygen spear and cutting objects - structures and structures (wall, barrier, overpass, premises, gates, door, container, wagon, bridge, etc.).

FIG. 1 - an oxygen spear in the first embodiment, that is, a spear with a hook bend angle of more than 0 ° and not more than 90 °, and the object of cutting.

FIG. 2 - an oxygen spear in the second embodiment, that is, a spear with a hook bend angle of more than 90 ° and not more than 180 °, and the object of cutting.

FIG. 3 - an oxygen spear in the third embodiment, that is, a spear with a hook bend angle of more than 180 ° and up to 270 ° or more, and a cutting object.

FIG. 4 - an oxygen spear in the second embodiment (see Fig. 2), but in one of the possible variations, when the hook bend with an angle of more than 90 ° and not more than 180 ° is made not in the final section of the oxygen spear, but, for example, in the middle its section, which further expands the operational capabilities of the oxygen spear. The cutting object is also shown here.

Oxygen spear 1 (Fig. 1), which includes a steel tube with metal wires inside it (not shown in the figure) made in the shape of a hook 2, in this case with a bend angle of more than 0 ° and not more than 90 °, namely with an angle of 90 °. The working output (burning) end face 3 of the spear 1 is facing the cutting object 4. The cutting operator 5 is located at the other input end of the spear and controls the spear. The burning end face 3 (Fig. 1) of the spear 1 destroys the object of cutting 4, gradually penetrating into it. With this cutting pattern, that is, in the "side" position, the safety of the cutting operator 5 is ensured in cases where at the place of the cut it is assumed or known that there is a danger to the cutting operator 5 (harmful substances in the material of the cutting object 4, explosives inside the object cutting, for example, on the other side of the wall, or the possibility of collapse of part of the object of cutting, or the presence of armed terrorists on the other side of the wall or the presence of other types of danger).

Oxygen spear 1 (Fig. 2), which includes a steel tube with metal wires inside it (not shown in the figure), made bent in the form of a hook 2, in this case with a bend angle of more than 90 ° and not more than 180 °, namely with an angle of 180 °. The working output (burning) end face 3 of the spear 1 is facing the cutting object 4. The cutting operator 5 is located at the other input side of the spear end and controls the spear. The need for such a variant of the spear and its operation are explained in the same way as in the previous case (Fig. 1), only in this case access to the place of cut is possible only in this way, that is, in the position "around the corner".

Oxygen spear 1 (Fig. 3), which includes a steel tube with metal wires inside it (not shown in the figure), made bent in the form of a hook 2, in this case with a bend angle of more than 180 ° and up to 270 ° and more, and with an angle of 270 °. The working, output, (burning) end face 3 of the spear 1 is facing the cutting object 4. The cutting operator 5 is located at the other input end of the spear and controls the operation of the spear. The need for such a variant of the spear and its operation are explained in the same way as in the case of FIG. 1, only here access to the place of cut is possible in this way, that is, in the position "because of two angles".

Oxygen spear 1 (Fig. 4), made according to the diagram of the drawing of Fig. 2, but with a bend of the hook with an angle of 180 ° not in the final section of the oxygen spear, but in its middle section, which gives the spear a U-shape, and this makes it possible to cut with the spear moving “towards itself”, which further expands those operational capabilities of the spear, which are partially implemented according to the scheme of FIG. 2.

Thus, the technical solution, which is the subject of the claimed utility model, provides a technical result and the task to which the claimed utility model is directed, namely, the expansion of the operational capabilities of the oxygen spear.
