Description

CLEANING APPARATUS FOR INNER-SURFACE OF ARTILLERY

The present invention relates to a barrel inner diameter cleaning device for always keeping the barrel (inside the barrel) clean at all times, which is essential in the cannon weapon system when the military fires a cannon, and more particularly, it is magnetically attached to the barrel by magnetization. A roller device that is mounted on the barrel by a fixed method and a mechanical element, and a material with high friction (for example, urethane, rubber, etc.) surrounds the outside. It is made in the shape of a long spherical shape so as to allow the The present invention, which is twisted by a roller device when reversing, is a washing device that cleans the inside of barrels of howitzers, direct fire guns, tank guns, anti-aircraft guns, self-propelled guns, mortars, and multiple rocket launchers, which are used in all units of the army, navy, and air force. More particularly, it has a conventional rod shape used for cleaning the inside of the barrel and has a washing rod and a washing brush in which a plurality of segments segmented in multiple stages are assembled in the axial direction, and the washing rod and the washing brush are easily inserted into the inside of the barrel Two long rollers that support the inlet and pull out, and a rotary handle for drawing in and withdrawing the cleaning rod and the cleaning brush from the inside of the barrel through transmission of rotational force to the long roller and the cleaning rod in and out of the barrel cleaning device it's about

The general conventional method for cleaning the inside of the barrel is to attach a cleaning brush to the end of the cleaning rod, and a large number of about 6-8 workers push the cleaning brush into the barrel and assemble a cleaning rod of about 4-8 meters. Wash by pushing and pulling for about 40 to 60 minutes.

Here, when a large number of workers hold a cleaning rod with a length of about 4 to 8 meters and move the cleaning rod back and forth, the movement force of the cleaning brush depends on the condition of each worker and whether the place to wash the barrel is a flat, open area or a slope. The washing state of the barrel appears differently depending on the surrounding environment, such as, and in the end, a problem occurs that the washing state inside the barrel is not uniform throughout the inside of the barrel depending on the conditions of the operator and the influence of the working environment. In addition, there is a problem that the working radius is at least 4 to 8 meters or more, which is the same as the length of the washing rod when washing the barrel. In addition, there is the inconvenience of having to separately install a guide ring device at the end of the barrel into which the cleaning rod enters, in order to prevent the cleaning rod from being scratched inside the barrel by touching the wall of the barrel.

In order to improve this, an automatic gun barrel washing device has been applied for or registered as in Application Nos. 10-2002-0019308, 10-2014-0070481, 10-2020-7016456, and 20-2003-0023436, and the invention and The design uses a power source such as a motor or cylinder to reciprocate in the axial direction through a guide roller that is inserted into the inner diameter of the barrel and in contact with the inner wall of the barrel. cylinder was driven.

However, the automatic method requires a high production cost as the production price is about 20 million won or more due to the installation of a separate power device such as electricity or pneumatic, and is an automatic method using electricity or pneumatic such as a motor or cylinder. When a defect occurs, it is very difficult to repair the equipment, and it takes a considerable amount of time to repair it, and a separate electric or pneumatic power source is required. For this reason, in the field, the use of automatic vacuum cleaners as described above is virtually absent, and the artillery personnel currently performing their missions judged that it is more efficient to manually clean the inside of the barrel rather than an automatic vacuum cleaner, The interior is being cleaned. In addition, in order to remove the defective charcoal loaded in the chamber, it is necessary to assemble a defective charcoal eliminator on the existing cleaning rod and manually apply an impact to remove it. For this purpose, the existing cleaning rod and cleaning brush must be continuously operated.

In addition, in Application No. 10-2015-0128981, a driving type muzzle cleaner is exemplified. A hammering device is placed on the cleaning rod that is combined with the cleaning brush, and when pushing and pulling the cleaning rod about 4 to 8 meters, the operator instantly strikes the cleaning rod strongly to clean the inside of the barrel. Manufacturers, inventors, or designers say that the number of workers is reduced by about 50% compared to the used barrel cleaning, and the cleaning time is reduced by about 50% for about 20 to 30 minutes.

However, the disadvantage of the striking type is that noise is generated when striking, and there is a risk of exposing the position of friendly positions to the enemy in combat situations. There is a problem that it does not work, and a working radius of about 4 to 8 meters with the cleaning rod fully assembled is required for the working radius. In addition, there is the inconvenience of having to separately install a guide ring device at the end of the barrel into which the cleaning rod enters, in order to prevent the cleaning rod from being scratched inside the barrel by touching the wall of the barrel.

Also, in Application No. 10-2015-0038936, an apparatus for washing the inside of the barrel using a cable chain replacing the cleaning rod and a winding device of the cable chain is exemplified in order to automatically draw in and withdraw the cleaning brush from the inside of the barrel.

For this device, a cable chain winding device must be installed separately, and the size of the cable chain winding device is large, making it inconvenient to use in the field. Also, there is a guiding roller device to prevent bending of the cable chain when the cable chain is drawn into the barrel. will be required separately. In conclusion, since the drive of the cable chain winding device uses electricity or pneumatic such as a motor or cylinder, it is a reality that it is very difficult to repair the equipment and it takes a considerable amount of time to repair the equipment when a defect occurs during the cleaning of the barrel. In order to remove the defective charcoal, it is necessary to assemble a defective charcoal remover on the existing cleaning rod and manually apply an impact to remove it.

In addition, in Application No. 10-2009-0113742, the wire is connected to both ends of the cleaning brush, and both ends of the wire are connected to the wire transfer device located on the shell inlet (closer) and shell discharge port (disposer) side of the barrel. Through this, a device for washing the inside of the barrel is exemplified while the cleaning brush is moved as the wire is selectively pulled from both ends of the outside of the barrel.

For the device, a separate wire transfer device must be separately installed at the shell inlet and the shell launcher, and one worker must be placed in the direction of the shell inlet and the shell launcher. In addition, in order to remove the defective bullets loaded in the chamber, it is necessary to assemble the defective coal eliminator on the existing cleaning rod and manually apply an impact to remove it.

The viscoelastic portion 125 may be a material including one or more of materials such as urethane, silicone, and rubber. Preferably, it may be a material containing urethane, and may have heat resistance and impact resistance. In addition, the outer diameter of the barrel 10 is rubbed against the viscoelastic part 125 to generate a frictional force so that the body 121 does not move along the outer peripheral surface of the barrel 10 .

The first roller 113 and the second roller 114 are geared and interlocked by assembling the first bracket 111 and the second bracket 112 , and are connected to the rotation shaft 113a of the second roller 114 . According to the rotation direction R of the manipulation unit 119 , the cleaning brush 201 may enter or be discharged from the barrel 10 . As described above, in the state in which the first bracket 111 and the second bracket 112 are assembled in the assembly direction A as shown in FIG. 2(b), the first roller 113 and the second roller 114 are interlocked. can be The interlocking means rotational interlocking by at least one gear-coupled portion.

A space corresponding to the diameter of the rod may be formed so that one of both ends of the roller is geared and the central portion of the roller can be moved. In order to provide such a space, the first roller 113 and the second roller 114 may be formed in a long ball shape (or an hourglass shape) to correspond to the radius of each rod. Corresponding here means that the portion in contact with the rod in the first roller 113 and the second roller 114 may be formed with a curvature less than or equal to the radius of the rod, and further, the contact surface is made of a high friction elastic material. can be formed.

This will be one of the conditions that can allow the first roller 113 to press the rod with a stronger force when the roller rotates so that the rod enters the inside of the barrel 10 or is discharged to the outside of the barrel 10. can

The bracket includes a body 121 and a slider 112a that can slide, and the body 121 includes a guide 121a corresponding to the slider 112a.

It is possible to minimize the number of working people to 1 or 2 when cleaning the machine, and the time can be reduced by more than 50% compared to the existing one.

Second, when the operator operates the rotary handle of the present invention, even with a small force of 10 to 15 kgf, a large thrust of about 150 to 200 kgf is generated, thereby reducing the convenience of operation and the fatigue of the operator.

Third, according to the speed at which the operator rotates the rotary handle of the present invention, the moving speed of the cleaning brush inside the barrel can be made faster or slower, so that fast work and fine washing work are possible.

Fourth, in the existing washing rod, after all the washing rod nodes are assembled in the axial direction, about 6 to 8 workers directly grip the washing rod by hand, then push it into the barrel and wash it. Although the radius varies depending on the length of the barrel, an average of about 6 to 10 meters is required, but the present invention allows the cleaning rod to be assembled or disassembled by pushing the cleaning rod into the barrel for a certain length or pulling it out of the barrel to minimize the working radius. can

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

In the description of the present invention, if it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. And, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

Conventionally, a large number of soldiers have been performing washing in a manner of reciprocating by putting a washing tool in the longitudinal direction of the barrel 10 for washing of the barrel 10 or automatically washing with an automatic washing device. However, washing by a large number of soldiers has a problem in that the washing efficiency is lowered while increasing the fatigue of the soldiers. Due to this problem, if the steel wire of the barrel 10 is unevenly worn and foreign objects such as bullets are not completely removed, it may be an obvious problem that the shooting accuracy is lowered.

On the other hand, one embodiment of the present invention is required to perform washing by attaching the drive system 100 to the end side of the barrel 10 and introducing the washing unit 200 into the barrel 10 through the drive system 100 . Relatively few people are required, and it has the advantage of being cheaper and lighter than automatic washing machines.

Through this, when attachment to the barrel 10 is required, the permanent magnet of the body 121 can be magnetized by manipulating the applying unit 126 adjacent to the barrel 10 .

Here, the magnetized and attached surface may be provided in a “V” shape. This is a structure for responding to various diameters of each barrel 10 . That is, the present invention is not limited thereto and may be formed in a bent shape such as a “C” shape. However, in response to the outer diameter of the barrel 10, a “V”-shaped surface may be preferable as in this example. A viscoelastic portion 125 may be formed on the surface to maintain an attached state. The viscoelastic portion 125 may be a material including one or more of materials such as urethane, silicone, and rubber. Preferably, it may be a material containing urethane, and may have heat resistance and impact resistance. In addition, the outer diameter of the barrel 10 is rubbed against the viscoelastic part 125 to generate a frictional force so that the body 121 does not move along the outer peripheral surface of the barrel 10 .
