Description

Technical Field

[0001] This invention relates to the field of gun cleaning equipment technology, and more particularly to a gun cleaning machine and a method for cleaning gun barrels. Background Technology

[0002] During artillery firing, the barrel operates in a high-temperature, high-pressure environment. Therefore, gunpowder residue and other contaminants adhere to the inner wall of the barrel, forming carbon deposits. Because the rifling inside a rifled cannon is spiral-shaped, these carbon deposits adhere to the grooves. If not cleaned promptly, the rifling will wear down during subsequent firings. Regarding cleaning methods, the pipeline robots currently in use in China are mainly for easily cleaned pipes such as air conditioning ducts, where dust is relatively easy to remove and the cleaning requirements are not very high. However, methods commonly used for cleaning complex internal surfaces include dry ice cleaning, gas blasting, and high-pressure water jet cleaning. These methods require sophisticated auxiliary equipment, are not portable, and cannot meet the requirements for weapon cleaning.

[0003] The cleaning and maintenance of artillery is of great significance for extending the life of artillery barrels and improving firing accuracy. A new application direction for portable high-efficiency artillery barrel cleaning machines is to quickly and efficiently clean and maintain the interior of artillery barrels. However, the internal space of artillery barrels is small and the internal surface is complex. How to clean the complex internal surface within a narrow and slender tube is a problem that artillery barrel cleaning machines urgently need to solve. Summary of the Invention

The brush mounting seat is equipped with a brush component for cleaning the inner wall of the gun barrel. The push rod component is located inside the hollow tube and is connected to a transmission component installed inside the hollow tube for moving the push rod mounting seat back and forth.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0034] During artillery firing, the barrel operates in a high-temperature, high-pressure environment. Therefore, gunpowder residue and other contaminants adhere to the inner wall of the barrel, forming carbon deposits. Because the rifling inside a rifled cannon is spiral-shaped, these carbon deposits adhere to the grooves. If not cleaned promptly, the rifling will wear down during subsequent firings. Regarding cleaning methods, the pipeline robots currently in use in China are mainly for easily cleaned pipes such as air conditioning ducts, where dust is relatively easy to remove and the cleaning requirements are not very high. However, methods commonly used for cleaning complex internal surfaces include dry ice cleaning, gas blasting, and high-pressure water jet cleaning. These methods require sophisticated auxiliary equipment, are not portable, and cannot meet the requirements for weapon cleaning.

[0035] The cleaning and maintenance of artillery is of great significance for extending the life of artillery barrels and improving firing accuracy. A new application direction for portable high-efficiency artillery barrel cleaning machines is to quickly and efficiently clean and maintain the interior of artillery barrels. However, the internal space of artillery barrels is small and the internal surface is complex. How to clean the complex internal surface within a narrow and slender tube is a problem that artillery barrel cleaning machines urgently need to solve.

[0036] This invention discloses a gun barrel cleaning machine, comprising several sets of hollow tubes 1 assembled together to form straight tubes 10. Each hollow tube 1 has several collars 2 on its exterior that contact the inner wall of the gun barrel. One end of each straight tube 10 is equipped with a push rod component 3. The outer ends of the push rods 4 of each push rod component 3 are connected to a brush mounting seat 5. The brush mounting seat 5 is equipped with a brush component 6 for cleaning the inner wall of the gun barrel. A push rod fixing seat 7 located inside the hollow tube 1 of the push rod component 3 is connected via a fixing seat 8 to a transmission component 9 installed inside the hollow tube 1 for moving the push rod fixing seat 7 back and forth. In practical application, this invention... By appropriately replacing the hollow tube 1 and its matching collar 2 to fit the diameter of the gun barrel to be cleaned, axial transmission is achieved through the transmission component 9, driving the push rod fixing seat 7 to move axially, thereby moving each push rod 4 axially, which in turn drives the brush component 6 axially, achieving effective cleaning of the inner wall of the gun barrel. This allows for efficient and rapid gun barrel cleaning, automatic wiping, saving time and effort, and causing no damage to the barrel. The barrel cleaning machine is lightweight and portable, suitable for operation in complex environments such as high altitudes and field conditions. The gun brush is replaceable and can be customized, suitable for cleaning and maintaining the barrels of various artillery pieces, including field guns, armored guns, aircraft cannons, and naval guns. It can be operated by a single soldier, improving the efficiency and quality of gun barrel cleaning.

[0037] Specifically, in one embodiment of the present invention, referring to the accompanying drawings, a gun washing machine includes two sets of hollow tubes 1 that are combined to form straight tubes 10. The two ends of the straight tubes 10 are respectively connected to collars 2 by threaded bolts. The connection between the two hollow tubes 1 is connected to collars 2 by threaded bolts. As shown in the figure, the two hollow tubes 1 and the three sets of collars 2 are assembled together. The hollow tubes 1 are provided with corresponding threaded holes for connection and assembly with the collars 2. Correspondingly, the collars 2 are also provided with threaded connection holes that mate with the threaded holes on the hollow tubes 1. Here, the collars 2 are made of nylon material, which gives the collars 2 good wear resistance and strong mechanical strength, so that the two hollow tubes 1 can be stably connected. As for the material of the hollow tubes 1, those skilled in the art can choose alloy materials or non-metallic materials with strong mechanical strength according to actual needs.

[0038] In the above embodiments of the present invention, end plates 101 and caps 102 are respectively provided at both ends of the straight tube 10, and a wall plate 103 is also provided between the two hollow tubes 1. The end plates 101 are used to cooperate with the push rod component 3. In order to cooperate with each push rod 4 in the push rod component 3, the end plates 101 have several openings, so that each push rod 4 can pass through the corresponding opening to complete the subsequent assembly. The caps 102 are used to seal the tail of the straight tube 10, while the wall plate 103 is used to cooperate with the transmission component 9, etc. 03 is located at one end of the hollow tube 1 near the brush component 6. The wall plate 103 is a circular plate. A connection hole for cooperating with the transmission component 9 is opened at the center of the wall plate 103. Several sets of dispersed mating holes of different sizes are also provided on the outer circumference of the connection hole. These mating holes are used to cooperate with the corresponding mating holes opened on the end plate 101 to install the corresponding support plate for supporting the transmission component 9. The specific configuration can be set according to actual needs, or it can be set with reference to the attached drawings of the embodiment of the present invention.

[0039] The above describes the installation structure between the two sets of hollow tubes 1 and corresponding accessories in this embodiment of the invention. This allows for the cleaning of different gun barrels by replacing the collar 2 or the corresponding hollow tube 1. To achieve cleaning of the inner wall of the gun barrel, this invention also includes a push rod component 3. Specifically, as shown in the attached drawings, the push rod component 3 includes a push rod fixing seat 7 disposed inside the hollow tube 1. Specifically, four sets of push rods 4 are connected to the side of the push rod fixing seat 7 opposite to the end plate 101. The four sets of push rods 4 pass through the end plate 101 and cooperate with the brush mounting seat 5. In this embodiment, the push rod fixing seat 7 has a cross-shaped structure. Each protrusion of the push rod fixing seat 7 is provided with a cylindrical countersunk hole that mates with each push rod 4. Correspondingly, the brush mounting seat 5 has the same shape as the push rod fixing seat 7. Each protrusion of the brush mounting seat 5 is provided with a cylindrical countersunk hole that mates with the push rod 4. In addition, a conical countersunk hole 51 that connects to the brush component 6 is also provided at the center of the brush mounting seat 5. The conical countersunk hole 51 has the same diameter as the output shaft of the transmission motor in the hollow tube 1 and the transmission component 9.

[0040] In addition, to ensure the stable guidance of each push rod 4, a copper sleeve 104 is fitted onto the end of each push rod 4 and mounted on the end plate 101. In this embodiment of the invention, since the base structure of the copper sleeve 104 is relatively large, it is not convenient to install it on the same side of the end plate 101. In order to ensure that the copper sleeve 104 can effectively cooperate with the end plate 101, the copper sleeve 104 is arranged in pairs on both sides of the end plate 101, which can further improve the stability of the axial movement of each push rod 4.

[0041] In this embodiment, the push rod fixing seat 7 is fitted with a fixing seat 8, which is used to cooperate with the transmission component 9 to achieve the axial movement of the push rod fixing seat 7 back and forth;

[0042] In this embodiment, the transmission component 9 includes a transmission motor 91, a bearing seat 92, a transmission wheel set 93, and a support assembly 94. The transmission motor 91 is mounted on the wall plate 103 located inside the hollow tube 1. The output shaft of the transmission motor 91 cooperates with the transmission wheel set 93 mounted on the bearing seat 92. The bearing seat 92 is mounted on the support assembly 94 located between the end plate 101 and the wall plate 103. The transmission wheel set 93 is connected to the fixed seat 8 through a transmission component mounted at its end. This enables the transmission motor 91 to drive the transmission wheel set 93 and transmit the power to the transmission component, thereby driving the fixed seat 8 to move axially back and forth. This allows the brush component 6 to move axially back and forth, thus achieving reciprocating cleaning of the inner wall of the barrel.

[0043] Specifically, the aforementioned support assembly 94 includes an upper support plate 941 and a lower support plate 942. The upper support plate 941 and the lower support plate 942 are respectively arranged in parallel between the end plate 101 and the wall plate 103. A certain space is left between the upper support plate 941 and the lower support plate 942 for assembling other accessories. Here, a bearing seat 92 is installed on the lower surface of the upper support plate 941. A transmission shaft 931 perpendicular to the fixed seat 8 is installed on the bearing seat 92. A bevel gear A932 is installed at one end of the transmission shaft 931. The bevel gear A932 meshes with a bevel gear B933. The bevel gear B933 is connected to the output shaft of the transmission motor 91. Here, the bevel gear B933 can be movably installed on the bearing seat 92 to mesh with the bevel gear A932, or it can be directly installed on the output shaft of the transmission motor 91 to mesh with the bevel gear A932, as shown in the attached figure of this embodiment. The specific installation position of the bevel gear B933 can be set by those skilled in the art according to actual needs.

[0044] In the above embodiment, a bevel gear A932 is fitted at one end of the drive shaft 931, and a threaded hole is provided at the other end of the drive shaft 931 to fit a transmission component 934. Here, a drive wheel 81 is mounted on the inner side of the fixed seat 8 relative to the drive shaft 931, and the transmission component 934 is connected to the drive wheel 81 for transmission. Here, an embodiment of the above structure is disclosed. Referring to the accompanying drawings, in order to realize the transmission cooperation between the transmission component 934 and the drive wheel 81, the transmission component 934 is a cam set on the drive shaft 931. The drive wheel 81 includes two sets of movable wheels symmetrically arranged on the side of the fixed seat 8 relative to the drive shaft 931. The cam is located between the two movable wheels, and the center of the cam and the center of the two movable wheels are on the same plane. This allows the fixed seat 8 to move along a straight line. In this embodiment, the upper support plate 941 and the lower support plate 942 are respectively provided with guide wheels 943 for clamping and guiding the fixed seat 8 on the side of the fixed seat 8. Specifically, in this embodiment, the guide wheels 943 are movably mounted on the connecting base that cooperates with the upper support plate 941 or the lower support plate 942. In this way, by providing two sets of guide wheels 943 on the upper support plate 941 and the lower support plate 942, the protrusion of the fixed seat 8 can be movably clamped. When the transmission shaft 931 rotates and transmits to the transmission component 934, i.e. the cam, the cam acts on the two movable wheels that cooperate with it, so that the fixed seat 8 reciprocates in the axial direction, thereby driving each push rod 4 to reciprocate, so that the brush component 6 mounted on the brush mounting seat 5 can reciprocate to clean the inner wall of the gun barrel.

[0045] In the above embodiments of the present invention, the present invention discloses a transmission structure in which the transmission component 934 is a cam that drives the drive wheel 81 to reciprocate through the fixed seat 8. To achieve the reciprocating linear motion of the fixed seat 8, the present invention can also employ other transmission structures. For example, the transmission component 934 is an eccentric cam, with a drive linkage externally connected to the eccentric cam. The drive linkage is movably connected to the drive wheel 81. Thus, the drive wheel 81 is driven by the eccentric cam, and guide wheels 943 are provided on the upper support plate 941 and lower support plate 942 to clamp and guide the fixed seat 8, thereby driving the fixed seat 8 to reciprocate axially, realizing the reciprocating cleaning of the inner wall of the gun barrel by the brush component 6. The above embodiment is another transmission method between the transmission component 934 and the drive wheel 81 disclosed in the present invention. The above structure can be implemented by those skilled in the art, and the accompanying drawings will not further describe this embodiment. Similarly, the present invention also has other transmission structures to achieve the reciprocating motion of the fixed seat 8 axially, such as the transmission component 934 including a transmission gear and a transmission... The rack and pinion mechanism is appropriately movably positioned within the space formed by the upper support plate 941 and the lower support plate 942 via corresponding accessories. The drive wheel 81 can engage with the rack and pinion. By setting the transmission motor 91 as a reciprocating drive motor, the reciprocating motion of the fixed seat 8 can be realized. The structure in this invention, where the transmission motor 91 engages with bevel gears A932 and B933 to drive the transmission component 934, which in turn engages with the drive wheel 81 to drive the fixed seat 8 to reciprocate axially, also includes other structures disclosed above. These will not be described further. Conventional technical improvements to the structure of product components, such as those made in specific embodiments of this invention, without departing from the essence of this invention, will also fall within the scope of this invention. The above description only illustrates certain exemplary embodiments of this invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the scope of this invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of the claims of this invention.

[0046] The brush component 6 is installed on the brush mounting base 5 as disclosed in this invention. The brush component 6 can simply consist of a brush, which can be threaded onto the brush mounting base 5. The brush structure can adopt a structure commonly used in the art, such as a simple connecting rod with a brush with bristles, or a connecting disc with bristles that mate with the gun barrel, etc. In this way, by selecting ELS high-efficiency copper removal cleaning agent, since copper is the most abundant and most difficult substance to remove in carbon deposits, if the copper can be removed, the other residues will become loose and easy to remove. At the same time, during the copper removal process, the corrosion inhibitor contained in the cleaning agent can form a dense protective film on the surface of the gun barrel material to prevent the cleaning solution from corroding the gun barrel material.

[0047] In other embodiments of the present invention, to improve the cleaning effect of the gun barrel and achieve composite cleaning of the gun barrel, the brush component 6 includes a brush 61 and a composite drive mechanism 62 for transmission. The composite drive mechanism 62 is mounted on the brush mounting base 5 and can realize the rotation of the brush 61. Specifically, the composite drive mechanism 62 includes a composite drive motor 621 and a composite sealing structure 622 that cooperates with the composite drive motor 621. The composite drive motor 621 drives the brush 61 to rotate, and the composite sealing structure 622 realizes the anti-fouling treatment of the composite drive motor 621. In this embodiment, the brush... The component 61 includes a connecting rod 611 that cooperates with the composite drive motor 621. The connecting rod 611 is provided with cleaning bristles 612. Specifically, the cleaning bristles 612 can be evenly distributed on the connecting rod 611 or can be wound around the connecting rod 611 in an auger shape. Those skilled in the art can configure the structure of the brush 61 according to actual needs. In this way, the brush component 6 rotates and cleans the inner wall of the gun barrel, and cooperates with the transmission component 9, the push rod component 3, and the fixed seat 8 to realize a composite scrubbing action of reciprocating rotation on the inner wall of the gun barrel, thereby improving the scrubbing effect on the gun barrel.

[0048] In one embodiment of the present invention, a collar 2 that contacts the inner wall of the gun barrel is respectively provided on the outside of the two hollow tubes 1. A push rod component 3 is installed at one end of the straight tube 10. The outer ends of each push rod 4 of the push rod component 3 are connected to the brush mounting seat 5. A brush component 6 for cleaning the inner wall of the gun barrel is installed on the brush mounting seat 5. The push rod fixing seat 7 located inside the hollow tube of the push rod component 3 is connected to a transmission component 9 installed inside the hollow tube 1 for realizing the back-and-forth movement of the push rod fixing seat 7 through a fixing seat 8. The transmission component 9 adopts the same technical solution as the aforementioned solution. In this embodiment, the difference between this solution and the aforementioned solution is that a friction block 945 that cooperates with the fixing seat 8 is provided between the upper support plate 941 and the lower support plate 942. The friction block 945 has a concave structure, and its notch can be movably engaged with the protrusion of the fixing seat 8 to guide the fixing seat 8 in axial movement.

[0049] In another embodiment of the present invention, the transmission component 9 includes an electric push rod with telescopic function and a support assembly 94. The support assembly includes an upper support plate 941 and a lower support plate 942, which have the same structure as in the aforementioned embodiment. The upper support plate 941 and the lower support plate 942 are respectively arranged in parallel between the end plate 101 and the wall plate 103. The telescopic end of the electric push rod is connected to the fixed seat 8 through a connecting component. A friction block 945 that engages with the fixed seat 8 is provided between the upper support plate 941 and the lower support plate 942. The friction block 945 has a concave structure, and its notch can movably engage with the protrusion of the fixed seat 8. In this way, the fixed seat 8 is directly driven by the electric push rod, and the fixed seat 8 can engage with the friction block 945, thus enabling direct... The fixed seat 8 is guided in axial movement. The specific embodiments disclosed in this invention fall within the scope of protection of the claims of this invention and are specific lower-level implementations of the feature parts of this invention. The protection content of the specific embodiments is merely an explanation of the scope of protection of the claims of this invention.

All product structural connection relationships that fall within the scope of protection of this invention are also within the scope of protection of this invention. Without departing from the essence of protection of this invention, conventional technical improvements to the structure of product components, such as the improvements to the structure of some parts of the product in the specific embodiments of this invention, will also fall within the essence of protection of this invention.

[0050] As can be seen from the above description, compared with the prior art, the present invention has the following significant advantages: simple structure, small size and weight, convenient installation, easy to carry and install, very convenient to use, can replace manual labor to achieve efficient automatic cleaning of the inner wall of the gun barrel, obvious cleaning effect, smooth and flexible transmission, fast speed, simple and precise control, no pollution, high efficiency, simple structure, no pipeline system, convenient maintenance. Due to the miniaturization and automation, and easy adjustment, it has strong adaptability and can meet the requirements of battlefield use. Moreover, it can easily combine cleaning machines of various lengths. At least one set of hollow tubes 1 is needed to complete the assembly of the device with the corresponding components, and the collar 2 can be adjusted to adapt to gun barrels of various calibers.

[0051] When performing gun barrel cleaning operations, the working process of the gun cleaning machine of the present invention includes the following steps:

[0052] First, based on the barrel's diameter and length, select a suitable collar 2 to match each hollow tube 1, place the cleaning machine inside the barrel, and set the cleaning speed of the cleaning machine. Control the transmission speed of the transmission motor 91 in the transmission component 9 according to the corresponding control software, control the reciprocating speed of the fixed base 8, thereby controlling the reciprocating wiping distance of the brush component 6. Manually control the flow control valve to allow an appropriate amount of cleaning fluid to flow onto the brush, improving cleaning quality. After the brush component 6 has cleaned a set distance, operate the sealing cap 102 at the rear end of the straight tube 10 using the operating lever to ensure the cleaning... The cleaning machine advances a certain distance into the gun barrel, and this process is repeated for the next distance to clean the inner wall of the gun barrel until cleaning is complete. Through the above steps, in conjunction with the embodiments disclosed in this invention, a composite cleaning method can be used to clean the gunpowder residue and some carbon deposits on the inner wall of the gun barrel. To improve the cleaning effect, those skilled in the art can reasonably set corresponding imaging components for the inner wall of the gun barrel on the device of this invention, such as adding a camera, or adding other detection elements to detect the inside of the gun barrel. Specifically, those skilled in the art can judge the cleaning effect according to the specific needs and make reasonable designs based on actual needs.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the scope of the invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of protection of the claims of this invention.
