Description

Gun body cleaning device {CLEANING APPARATUS FOR INNER-SURFACE OF ARTILLERY}

The present invention relates to a gun barrel inner diameter cleaning device for keeping the gun barrel (inside the gun barrel) clean at all times, which is essential in a gun weapon system when shooting a gun in the military, and more particularly, magnetically attached to the gun barrel by magnetization, A roller device that is mounted on the gun barrel by a fixed method and mechanical elements, and a material with high friction (eg, urethane, rubber, etc.) wraps the outside. The twist rod is positioned between the two roller devices, and at least one of the two roller devices performs a motion called a cam lock through an arc-shaped cam lock groove, and through this cam lock movement, the twist rod moves forward or The present invention, which has a skewer by a roller device when moving backward, is a cleaning device for cleaning the inside of a gun barrel such as a howitzer, a direct gun, a tank gun, an anti-aircraft gun, a self-propelled gun, a mortar, and a multiple rocket launcher used in all units regardless of the army, navy, and air force. More specifically, a washing rod and a washing brush in which a plurality of segments segmented in multiple stages are assembled in the axial direction in a conventional rod shape used when cleaning the inside of a gun barrel, and the washing rod and the washing brush easily enter the inside of the gun barrel In a washing rod drawing-out washing device equipped with a rotating handle for drawing in and withdrawing the washing rod and the cleaning brush into the barrel by transmitting rotational force to the two long-shaped rollers and the long-shaped rollers that support the drawing-in and drawing-out of the washing rod and the washing brush. it's about

For cleaning the inside of the gun barrel by a conventional conventional method, a washing brush is attached to the tip of the washing rod, and a number of workers of about 6 to 8 people push the washing brush into the barrel, and the assembled washing rod is about 4 to 8 meters long. Wash by pushing and pulling for about 40 to 60 minutes.

Here, when a number of workers hold a washing rod having a length of about 4 to 8 meters and move the washing rod back and forth, the moving force of the washing brush depends on the condition of each worker and whether the place where the gun barrel is washed is a flat open field or a slope. Depending on the surrounding environment of the back, the washing state of the gun barrel appears differently, and this eventually causes a problem that the washing state inside the gun barrel is not uniform throughout the inside of the gun barrel according to the influence of the worker's condition and working environment. In addition, there is a problem in that the working radius is required to be at least 4 to 8 meters, which is equal to the length of the washing rod, during the gun barrel washing operation. In addition, it is inconvenient to separately install a guide ring device for preventing scratches on the inside of the gun barrel when the washing rod touches the wall of the gun barrel at the end of the gun barrel into which the washing rod is inserted.

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

However, the automatic method requires a high production cost of about 20 million won or more due to the installation of a separate power device such as electricity or pneumatics, and it is an automatic method using electricity or pneumatics such as a motor or cylinder. In the event of a defect, it is very difficult to repair the equipment, it takes a considerable amount of time to repair, and a separate electricity or pneumatic power source is required. For this reason, the use of automatic cleaners as described above is virtually non-existent in the field, and artillery personnel currently on duty judge that it is more efficient to manually clean the inside of the gun barrel rather than automatic cleaners, so they are currently manually cleaning the gun barrel. The inside is being cleaned. In addition, in order to remove the defective ammunition loaded in the chamber, it is necessary to assemble the defective ammunition remover to the existing washing rod and manually apply an impact to remove it, but for this, the existing washing 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 so that when the worker pushes and pulls the cleaning rod at a distance of 4 to 8 meters, the worker instantly strikes the cleaning rod strongly to clean the inside of the gun barrel. The manufacturer, inventor or contributor discloses that the number of workers is reduced by about 50% compared to the washing machine using 3 to 4 people, and the washing time is reduced by about 50% for about 20 to 30 minutes.

However, the disadvantage of the strike type is that noise is generated when hitting, and there is a risk of exposing the position of the friendly camp to the enemy in a combat situation. Also, the cleaning brush moves inside the gun barrel at the moment of hitting, so the inside of the gun barrel is not cleaned uniformly. There is a problem that does not work, and the working radius requires a working radius of about 4 to 8 meters with the washing rod completely assembled. In addition, it is inconvenient to separately install a guide ring device for preventing scratches on the inside of the gun barrel when the washing rod touches the wall of the gun barrel at the end of the gun barrel into which the washing rod is inserted.

In addition, Application No. 10-2015-0038936 exemplifies a device for cleaning the inside of the gun barrel using a cable chain replacing the washing rod and a winding device of the cable chain to automatically withdraw and withdraw the washing brush from the inside of the gun barrel.

The device requires a cable chain winding device to be installed separately, and the size of the cable chain winding device is large, making it inconvenient to use in the field. will be required separately. In conclusion, since the drive of the cable chain winding device uses electricity or pneumatics such as a motor or cylinder, it is a reality that it is very difficult to repair the equipment when a equipment defect occurs during gun barrel cleaning and it takes a considerable amount of time to repair it. In order to remove the defective coal, it is necessary to assemble the defective coal remover to the existing cleaning rod and manually apply a shock 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 launcher (closer) side of the gun barrel. Through this, a device for cleaning the inside of the gun barrel while the cleaning brush is moved by selectively pulling the wire from both ends of the gun barrel is exemplified.

For the device, a separate wire transfer device must be 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 ammunition loaded in the chamber, it is necessary to assemble the defective ammunition remover to the existing washing rod and manually apply an impact to remove it.

The cleaning brush 201 may employ a metal thread and may be formed with a diameter greater than or equal to the radius of the gun barrel 10 from the central axis of the rod.

According to one embodiment of the present invention, cleaning is performed by attaching the driving system 100 to the end side of the gun barrel 10 and introducing the cleaning unit 200 into the gun barrel 10 through the driving system 100 .

The driving system 100 attached to the gun barrel 10 can be selectively magnetized and attached to the extended end of the gun barrel 10 . And, the rollers described above include the first roller 113 and the second roller 114, specifically, the first roller 113 that presses the rod from one side and the second that presses it from the other side when coupled with the rod. A roller 114 may be included. Therefore, the gun barrel 10 is pressurized by the pressurization of the first roller 113 and the second roller 114 and can be moved along the rotational direction R of the roller. That is, the first roller 113 and the second roller 114 pressurize and rotate the rod so that the cleaning unit 200 can enter or exit the gun barrel 10 .

The aforementioned bracket includes a first bracket 111 and a second bracket 112. The first bracket 111 may be connected to the rotation shaft 113a of the first roller 113, and the second bracket 112 may be connected to the rotation shaft 113a of the second roller 114. Each bracket is formed in a “c” shape and may be connected to the rotation shaft 113a of the roller. It includes a second bracket 112, and the first bracket 111 and the second bracket 112 are coupled to each other by a hinge 111a to selectively configure an assembled state.

According to one embodiment of the present invention, the body 121 has a built-in permanent magnet that is selectively magnetized, and the gun barrel 10 can be attached to the body 121 by magnetization. Here, magnetization may be selectively performed by manipulating the application unit 126 . Through this, when attachment to the gun barrel 10 is required, the permanent magnet of the body 121 can be magnetized by manipulating the applying unit 126 adjacent to the gun barrel 10 .

In addition, the attached surface is not limited to a "V" shape, but may be formed in a bent shape such as a "c" shape. However, in corresponding to the outer diameter of the gun barrel 10, a “V” shaped surface may be preferable, as in this example. A viscoelastic part 125 may be formed on the surface to maintain an attached state. The viscoelastic part 125 may be a material containing at least one of materials such as urethane, silicone, and rubber. It may preferably be a material containing urethane, and may have heat resistance and impact resistance. In addition, the outer diameter of the gun barrel 10 is rubbed against the viscoelastic part 125 to generate frictional force so that the body 121 does not move along the outer circumferential surface of the gun 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 connected to the rotation shaft 113a of the second roller 114. The cleaning brush 201 may enter or exit the gun barrel 10 according to the rotation direction R of the control unit 119 . As described above, when 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 interlock. It can be. The interlocking means rotational interlocking by means of at least one geared part.

One of both ends of the roller may be gear-coupled, and a space corresponding to the diameter of the rod may be formed in the central portion so that the rod may move. 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 hourglass shape) to correspond to the radius of each rod. Here, the meaning of correspondence means that the part in contact with the rod in the first roller 113 and the second roller 114 can be formed with a curvature less than the radius of the rod, and furthermore, the contact surface is made of a high friction elastic material. can be formed

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

The bracket includes a body 121 and a slideable slider 112a, and the body 121 includes a guide 121a corresponding to the slider 112a. Specifically, the slider 112a is formed on the second bracket 112 . Here, the slider 112a and the guide 121a may be connected by a “T” shape or a dovetail shape to slide along the extension direction of the guide 121a. Here, the slide may be one of structures corresponding to the diameter of the gun barrel 10 seated on the viscoelastic part 125 . That is, as the diameter increases, it is seated on the upper end of the viscoelastic part 125, and the position of the centrifugal position of the gun barrel 10 seated on the upper end can also be adjusted upward. Therefore, it can be adjusted to correspond to the centrifuge through the guide 121a-slider 112a, and adjusting to correspond to the centrifugal means that the rod to be drawn into the gun barrel 10 and the centrifugal can be coaxially arranged It means to adjust.

In the bracket that can be variably adjusted up and down, the second bracket 112 and the body 121 may be fixed at a predetermined position corresponding to the gun barrel 10 .

At this time, the first roller 113 may be extended so as to be further pressed toward the rod side. That is, in the curved long hole 111b, the long hole extends downward in a curved direction, the first roller 113 is rotated, and the rotating shaft 113a of the first roller 113 can be moved along the extending direction of the long hole. . That is, when the gripping force is required, the curved long hole 111b is formed in the direction and downward direction in which the cleaning unit 200 is moved into the gun barrel 10, and the washing unit 200 is moved to the outside of the gun barrel 10 so that the pressing force can be increased when gripping force is required. It may extend along a curve in the moving direction and downward. An arbitrary extension line CL shown may be a direction in which the curved long hole 111b extends.

When the bracket is vertically disposed, the rod may be more strongly pressed while the first roller 113 moves downward. In order to alleviate wear by pressing and increase the pressing force, the surface of the roller contacted during pressing may be made of a high-friction material such as rubber.

As described above, representative embodiments of the present invention have been described in detail as a means of solving the problems, but those skilled in the art to which the present invention belongs will not deviate from the scope of the present invention with respect to the above-described embodiments. It will be appreciated that many variations are possible within. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.

First, when the present invention uses a washing rod that is commonly used in the past, the washing rod is brought into close contact with the long-shaped roller, and the long-shaped roller is rotated as a rotating handle to freely reciprocate the washing rod in the axial direction of the gun barrel. It is possible to minimize the number of workers to 1 or 2 people when washing, and the time can be reduced by more than 50% compared to the existing one.

Second, when the operator manipulates the rotating handle of the present invention, a large thrust of about 150 to 200 kgf can be generated even with a small force of 10 to 15 kgf, thereby reducing work convenience and operator fatigue.

Third, the moving speed of the cleaning brush inside the gun barrel can be increased or decreased according to the speed at which the rotating handle of the present invention is rotated by the operator, so that fast and fine cleaning work is possible.

Fourth, in the existing washing rod, after fastening all the parts of the washing rod, which are assembled in the axial direction, with a plurality of segments segmented in multiple stages, about 6 to 8 workers manually grip the washing rod, push it into the barrel, and wash it. Although the radius varies depending on the length of the gun barrel, an average of 6 to 10 meters was required. can

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

In describing the present invention, if it is determined that a detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or operator. Therefore, the definition should be made based on the contents throughout this specification.

The technical spirit of the present invention is determined by the claims, and the following examples are only one means for efficiently explaining the technical spirit of the present invention to those skilled in the art to which the present invention belongs.

Hereinafter, a device capable of cleaning the inside of the gun barrel 10 will be described through embodiments of the present invention. Embodiments described below are coupled to the end side of the gun barrel 10 to reciprocate the cleaning brush 201 inside the gun barrel 10, and are magnetically attached to the gun barrel by magnetization and fixed in a manner and mechanical way. It includes a method of attaching to the gun barrel 10 through an element. Therefore, it is natural that the features to be described later, excluding the differences between the two methods classified as above, are applicable even when a separate description is omitted.

1 is a view showing a gun barrel cleaning device and gun barrel 10 according to an embodiment of the present invention.

Referring to FIG. 1, the washing machine 200 includes a washing brush 201 that enters the machine gun 10 and is positioned in front of the entry direction and one or more rods connected to the washing brush 201. include And, a roller that pressurizes the cleaning unit 200 and enters the inside of the gun barrel 10 through rotation, a bracket for fixing the roller, and a body 121 connected to the bracket and coupled to the gun barrel 10 through magnetism.

Here, one or more washing brushes 201 may be provided at an end of one or more connected rods and may be formed to extend outward from an outer circumferential surface. The cleaning brush 201 may employ a metal thread and may be formed with a diameter greater than or equal to the radius of the gun barrel 10 from the central axis of the rod. Conventionally, a number of soldiers have been cleaning the gun barrel 10 by putting a cleaning tool in the longitudinal direction of the gun barrel 10 and reciprocating, or by providing an automatic washing device to automatically wash the gun barrel 10 . However, washing by a large number of soldiers increases the fatigue of the soldiers, while the washing efficiency is low, and the automatic washing method has the disadvantage of having to carry an expensive automatic washing machine separately. Due to this problem, if the steel wire of the gun barrel 10 is worn unevenly and foreign substances such as bullets are not completely removed, it may be an obvious problem that shooting accuracy is lowered.

On the other hand, one embodiment of the present invention is required to perform washing by attaching the driving system 100 to the end side of the gun barrel 10 and introducing the cleaning unit 200 into the gun barrel 10 through the driving system 100. It has the advantage of being relatively small in number and cheaper and lighter than automatic cleaning devices.

And, the rollers described above include the first roller 113 and the second roller 114, specifically, the first roller 113 that presses the rod from one side and the second that presses it from the other side when coupled with the rod. A roller 114 may be included. Therefore, the gun barrel 10 is pressurized by the pressurization of the first roller 113 and the second roller 114 and can be moved along the rotational direction R of the roller. That is, the first roller 113 and the second roller 114 pressurize and rotate the rod so that the cleaning unit 200 can enter or exit the gun barrel 10 .

In addition, the aforementioned bracket includes a first bracket 111 and a second bracket 112. The first bracket 111 may be connected to the rotation shaft 113a of the first roller 113, and the second bracket 112 may be connected to the rotation shaft 113a of the second roller 114. Each bracket is formed in a “c” shape and may be connected to the rotation shaft 113a of the roller.

Meanwhile, the body 121 has a built-in permanent magnet that is selectively magnetized, and the gun barrel 10 can be attached to the body 121 by magnetization. Here, magnetization may be selectively performed by manipulating the application unit 126 . Through this, when attachment to the gun barrel 10 is required, the permanent magnet of the body 121 can be magnetized by manipulating the applying unit 126 adjacent to the gun barrel 10 .

Here, the surface to be magnetized and attached may be provided in a “V” shape. This is a structure to correspond to various diameters of each barrel 10. That is, it is not limited thereto and may be formed in a bending shape such as a “c” shape. However, in corresponding to the outer diameter of the gun barrel 10, a “V” shaped surface may be preferable, as in this example. A viscoelastic part 125 may be formed on the surface to maintain an attached state. The viscoelastic part 125 may be a material containing at least one of materials such as urethane, silicone, and rubber. It may preferably be a material containing urethane, and may have heat resistance and impact resistance. In addition, the outer diameter of the gun barrel 10 is rubbed against the viscoelastic part 125 to generate frictional force so that the body 121 does not move along the outer circumferential surface of the gun barrel 10 .

Furthermore, a structure configured to correspond to various diameters of the gun barrel 10 may also be provided in the bracket. This will be described in detail with reference to FIG. 3 below.

In addition, 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 the rotation shaft 113a of the second roller 114 The cleaning brush 201 may enter or exit the gun barrel 10 according to the rotation direction R of the control unit 119 connected thereto. As described above, when 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 interlock. It can be. The interlocking means rotational interlocking by means of at least one geared part.

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 hourglass shape) to correspond to the radius of each rod. Here, the meaning of correspondence means that the part in contact with the rod in the first roller 113 and the second roller 114 can be formed with a curvature less than the radius of the rod, and furthermore, the contact surface is made of a high friction elastic material. can be formed

This will be one of the conditions allowing the first roller 113 to press the rod with a stronger force when the roller rotates so that the rod enters the gun barrel 10 or is discharged to the outside of the gun barrel 10. can In this regard, it will be described later in more detail with reference to FIG. 4 .

Referring to FIG. 3 , the bracket includes a body 121 and a slideable slider 112a, and the body 121 includes a guide 121a corresponding to the slider 112a. Specifically, the slider 112a is formed on the second bracket 112 . Here, the slider 112a and the guide 121a may be connected by a “T” shape or a dovetail shape to slide along the extension direction of the guide 121a. Here, the slide may be one of structures corresponding to the diameter of the gun barrel 10 seated on the viscoelastic part 125 . That is, as the diameter increases, it is seated on the upper end of the viscoelastic part 125, and the position of the centrifugal position of the gun barrel 10 seated on the upper end can also be adjusted upward. Therefore, it can be adjusted to correspond to the centrifugal force through the guide 121a-slider 112a.

Here, adjusting to correspond to the centrifugal is to adjust so that the rod to be drawn into the gun barrel 10 and the centrifugal are coaxially disposed, and the position of the roller on which the rod is seated and pressed can be adjusted up and down. To this end, the bracket connected to the roller can be adjusted to be coaxial by adjusting the body 121 as a reference.

As described above, the second bracket 112 and the body 121 of the bracket that can be variably adjusted up and down can be fixed at a predetermined position corresponding to the gun barrel 10 . Fixing may be performed through the fixing part 112b. The fixing portion 112b is coupled to the slider 112a side of the second bracket 112 through a fastener such as a bolt, and through the coupling, the guide 121a and the slider 112a are fixed through the coupling through the fixing portion 112b. It can be.

4 is a view showing the first roller 113 coupled to the first bracket 111 according to an embodiment of the present invention.

Referring to FIG. 4, the first bracket 111 has a curved long hole 111b connected to the rotational shaft 113a of the first roller 113, and the curved long hole 111b is a washing part ( When the 200 enters and exits, the first roller 113 may be extended to further press the rod side. That is, in the curved long hole 111b, the long hole extends downward in a curved direction, the first roller 113 is rotated, and the rotating shaft 113a of the first roller 113 can be moved along the extending direction of the long hole. . That is, when the gripping force is required, the curved long hole 111b is formed in the direction and downward direction in which the cleaning unit 200 is moved into the gun barrel 10, and the washing unit 200 is moved to the outside of the gun barrel 10 so that the pressing force can be increased when gripping force is required. It may extend along a curve in the moving direction and downward. An arbitrary extension line CL shown may be a direction in which the curved long hole 111b extends.

When the bracket is vertically disposed, the rod may be more strongly pressed while the first roller 113 moves downward.
