Washing apparatus for inner-surface of artillery}

The present invention relates to a device for cleaning the inner diameter surface of a fabric having a long gun barrel, such as self-propelled artillery or a variety of traction gun, and developed to clean the inside of the barrel quickly and easily by breaking the conventional cleaning method performed by manpower It relates to a gun barrel cleaning device.

As a long-range firepower, various artillery is an important tool, and conventional towing and self-propelled artillery are being developed. These cannons have long barrels, with many steel wires forming continuous grooves.

In the maintenance of the gun, it is necessary to remove the gunpowder remaining in the barrel after shooting, and it is necessary to properly prevent the rust on the inner surface of the barrel.

Taking the case of the towing gun as an example, a description will be given of the internal cleaning of the barrel by hand. In normal or firing shots, the barrel is inclined towards the target to maintain its position. If you want to clean the barrel, place the barrel horizontally and roll the mop at the end of a long rod to clean the barrel by repeating multiple people's push. This conventional method has a problem that not only time but also a lot of manpower is required and cleaning is possible after keeping the barrel horizontal. That is, in an urgent situation there is a need for continuous shooting to be performed and therefore a cleaning operation without changing the position of the barrel is possible.

As a prior art, the automatic cleaning device of Pohang of South Korea Patent Registration No. 1995-0014497 has been presented, and Figure 1 is a schematic cross-sectional view thereof.

As shown in FIG. 1, the driving unit 10 is mounted with a driving motor 11 so as to be variable in speed, and one end of the driving unit 12 is linked to the driving motor 11, and a driving unit ( 10) can be driven by the support 20 connected to the other end of the drive means 12 to support the drive means 12 and the drive means 12 connected to the support 20 and the drive unit 10 It is characterized by consisting of a cleaner (30) to be addressed.

Automatic cleaning device according to the prior art can be seen that the cleaner is moved along the drive means by the drive motor after the drive and support separately installed on the front and rear sides of the barrel. The automatic cleaning device of such a structure has the advantage that it is possible to clean the steel by replacing the manpower, but since it is composed of a plurality of separate members, it takes a long time to install and maintenance is difficult.

In addition, the above-described automatic cleaning device for the steel wool cannot be supplied with the cleaning oil to the cleaner once installed in the barrel, and thus, there is a problem in that the driving unit has to be dismantled from the barrel in order to supply new cleaning oil or replace the cleaner. have.

In order to solve this problem, an internal diameter washing apparatus of Patent No. 10-2001-0066827 previously filed by the applicant of the present invention has been presented. Attached Figure 2 shows a schematic appearance of the cloth inner diameter washing apparatus.

The construction includes control means inserted into the inner diameter of the barrel and automatically operated, guiding means driven under the control of the control means and guided by the guide rollers, and driven by the control means. It is composed of a spray means for flowing out the washing liquid and the cooling liquid filled therein, a speed reducer driven by the control of the control means and a cleaning means for cleaning the barrel inner diameter by rotating in connection with the speed reducer.

In the case of the inner diameter washing apparatus described above, the guide roller is provided only in the head portion, and thus, when the head portion passes through the barrel, the supply of force for pushing the washing apparatus upward is blocked. That is, when the head portion is out of the barrel, only the cleaning means formed on the rotating body rotates while contacting the inner diameter of the barrel. In this state, the washing apparatus does not proceed at the initial speed.

In particular, in a state where the barrel is steeply inclined, such a phenomenon is prominent, and there is a problem in that it does not function properly.

In addition, since the position of the injection hole is formed to be spaced apart from the cleaning means, when the high heat occurs, the cleaning oil is injected after the cleaning oil is injected before the cleaning means passes through the point. Have

In addition, as the rotating body formed from the body rotates, the rotational force is also exerted on the upper end of the body, that is, the head and the control means. It has the problem of causing wear and damage.

Therefore, the present invention devised to solve the above problems is configured to install a cleaning unit for cleaning the inner diameter surface of the barrel between the two drive motors and to form a cleaning liquid and a friction member adjacent to cope with the rapid vaporization of the cleaning liquid. An object of the present invention is to provide an internal cleaning device for the barrel.

In addition, another object of the present invention is to provide an internal cleaning apparatus for the barrel in which the movement of the friction member of the cleaning unit is linearly stiffened to prevent the cleaning apparatus from being rotated in progress.

In addition, the inner barrel cleaning apparatus according to the present invention also provides an inner barrel cleaning apparatus having a function that can be prevented after the inner barrel mirror cleaning.

In addition, the nonwoven fabric layer 50 may be further attached to the rear side of the rear drive motor 20b so as to finally wipe the barrel inner diameter surface and apply rust preventive oil.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 3 is a schematic external view of the inner barrel cleaning apparatus constructed according to an embodiment of the present invention, Figure 4 corresponds to a cross-sectional view showing the inside of FIG.

A cylindrical elongated case 10 is provided, and the front and rear ends thereof become the driving unit 20. That is, the front drive motor 20a and the rear drive motor 20b are internally installed in the front and rear sides of the case 10, and the removable batteries 11 are coupled to each other.

The front drive motor 20a drives the front shaft 21 and the front drive wheel 22, and the rear drive motor 20b rotates the rear shaft 21-1 and the rear drive wheel 22-1. do. One side end of the front shaft 21 is fastened to an end of the rotation shaft of the front drive motor 20a, and both front and rear ends of the front shaft 21 are supported by bearings.

In addition, a worm 21a is installed in the space portion between the two bearings supporting the front shaft 21. The worm 21a is a gear having teeth in the axial direction of the front shaft 21 and rotates in association with the front drive motor 20a.

On the other hand, the other end of the front shaft 21, that is, the side opposite end that is engaged with the front drive motor (20a) is prolonged protruding from the bearing and the first bevel gear (21b) is coupled to the end. The first bevel gear 21b is engaged with the second bevel gear 34a of the washing unit 30 to be described later to transmit power.

In response to the worm 21a, the front driving wheels 22 are installed on the outer circumferential surface of the case 10 at equal intervals, and in this embodiment, three fronts are disposed at 120 degree intervals on the outer surface of the case 10. The driving wheel 22 is to be coupled. FIG. 5 is a cross-sectional view of the A-A line in FIG. 4, and it can be seen that three front driving wheels 22 are engaged with the worm 21a.

Rotating pins 22c are formed on the outer surface of the case 10 at which the front drive wheels 22 are installed, at three intervals at equal intervals, and the rotation shafts of the front drive wheels 22 are formed at both ends of the openings. Is combined. A more detailed structure of the front drive wheel is as follows.

The front drive wheel 22 is largely divided into two head portions, and a tooth gear is formed at the center portion so as to be engaged with the worm 21a. It consists of the tire 22b. As shown in FIG. 5, when the worm gear 22a and the tire 22b are coupled to each other, an overall shape of the gear is formed.

On the other hand, the center portion of the worm gear (22a) is composed of an empty space, the rotation pin 22c is inserted into the front drive wheel 22 is mounted in the opening formed in the case 10.

And the structure of the rear drive motor 20b, the rear shaft 21-1 and the rear drive wheel 22-1 constituting the drive unit 20 is the front shaft 21 and the front drive wheel coupled to the front drive motor ( Same as 22). However, the first bevel gear is not formed in the rear shaft.

The power generated by the front drive motor 20a basically rotates the front drive wheel 22 to generate propulsion force, and drives the washing unit 30 and the spray unit 40, whereas the rear drive motor ( 20b) drives only the rear drive wheel 22-1 to provide a driving force to advance the cleaning device.

Of course, it may be possible to separate the control of the front drive motor and the rear drive motor, but in the embodiment of the present invention is configured to perform the simultaneous control. Thus, the reason for the simultaneous control of the front drive motor and the rear drive motor is as follows.

The front drive motor 20a side is inserted into the barrel first, and the front drive motor 20a side first exits the barrel. Therefore, the front drive wheel 22 no longer generates propulsion force, but the washing unit located inside the barrel needs to be operated until it completely exits the barrel. As will be described later, the driving of the washing unit 30 has to be rotated in relation to the front driving motor 20a until the washing unit 30 completely exits the barrel. Therefore, it is necessary to control the front drive motor 20a and the rear drive motor 20b at the same time.

Next, the cleaning unit 30 will be described. The washing unit 30 is formed between the front drive motor 20a and the rear drive motor 20b as shown in FIG. 4 and is a synthetic resin layer 32b that is linearly moved by the rotational force of the front drive motor 20a. ) And the adsorption layer 32c remove foreign substances on the inner surface of the barrel.

The synthetic resin layer 32b and the adsorption layer 32c, which are alternately inserted into the outer surface of the mounting plate 32a, remove foreign substances while making direct contact with the inner barrel surface, and the synthetic resin layer 32b is a rather hard material. The adsorption layer 32c is composed of a material having a good adsorption capacity such as a sponge and a soft material. That is, the synthetic resin layer and the adsorption layer are alternately formed so that foreign matters dropped by the synthetic resin layer can be absorbed in the adsorption layer.

As the synthetic resin layer and the adsorption layer, soft plastics, nonwoven fabrics, etc. may be used, and various materials may be used as materials suitable for this purpose.

When the synthetic resin layer 32b and the adsorption layer 32c are formed on the mounting plate 32a, the fixing nuts 32a-2 of the mounting plate 32a are separated, and the respective thinly cut synthetic resins or absorbent materials are separated by a predetermined width. Overlaid one layer of synthetic resin layer and adsorption layer, and then second synthetic resin layer and adsorption layer are formed. After inserting the appropriate thickness of the synthetic resin layer 32b and the adsorption layer 32c into the mounting plate 32a, the fixing nuts 32a-2 are recombined again so that the synthetic resin layer and the adsorption layer stopper 32a-1. ) And the fixing nut (32a-2).

Next, the injection unit 40 will be described. The injection unit 40 is a portion that functions to supply the cleaning liquid stored in the cleaning container 44 in the atomized state to the front of the friction member 32. The injection unit 40 is largely composed of a piston 41, a check valve 42 and the injection pipe 43, and the check valve 42 is selectively opened and closed by the pumping operation by the piston 41. Finally, the cleaning liquid in the atomized state is injected through the fine holes 43a formed in the injection pipe 43.
