Description

Technical Field

[0001] This solution belongs to the field of military auxiliary equipment technology, specifically involving a gun cleaning device. Background Technology

[0002] The barrel is a rifled cannon that uses projectiles with a copper stripe. After firing the projectile, copper residue remains on the barrel walls, both the bore and breech. If this copper residue is not removed promptly, it will significantly reduce the barrel's lifespan and decrease firing accuracy. Therefore, removing copper residue from the barrel is a primary function of the barrel cleaning machine. Effectively removing the copper residue from the bore and breech walls is a key design challenge.

[0003] A portable blotting machine, with publication number CN216482509U, includes a bracket, a rotating shaft, a drive component, a turntable, a drive rod, a first elastic element, and a brush. The bracket houses the rotating shaft, which is driven to rotate on the bracket by the drive component. A turntable is fixedly mounted on the rotating shaft, and a drive rod is abutted against one end of the turntable. The other end of the drive rod is connected to the brush.

[0004] For example, the aforementioned barrel cleaning machine uses a drive mechanism to rotate a rotating shaft and turntable, which in turn drives a brush to perform circumferential revolutions to clean the gun barrel. However, during firing, the copper bullet band gets stuck into the helical rifling, forming a strongly bonded, compacted copper layer on the guide side of the positive rim. The radially arranged brushes of this device only move along the circumferential tangential direction. After the brush bristles make perpendicular contact with the sidewall of the positive rim, they are prone to bending and slipping. Furthermore, the movement trajectory intersects with the helical rifling, resulting in only intermittent spot cleaning of the sidewall. The sliding friction in one direction cannot continuously rub and peel off the compacted copper layer on the guide side, making it difficult to remove the copper residue. Summary of the Invention

[0005] This invention provides a gun cleaning device to improve the cleaning effect of existing gun cleaning machines.

[0006] This invention provides a cleaning device, including a housing and a driving device disposed on the housing. The housing has a first cleaning device arranged along its axial direction. The output end of the driving device is connected to the first cleaning device for driving the first cleaning device to rotate circumferentially around the axis of the housing. The device also includes a second cleaning device, which comprises: The second cleaning component is rotatably mounted on the housing. The second cleaning component is arranged radially along the housing, and the rotation axis of the second cleaning component is perpendicular to the rotation axis of the first cleaning device. The transmission component has the second cleaning component mounted on it. The output end of the drive device is connected to the transmission component to drive the transmission component to rotate, causing the second cleaning component to rotate circumferentially around its own axis.

[0007] The principle and effect of this solution are as follows: After the drive device outputs power, it drives the first cleaning device to rotate circumferentially around the housing axis, covering the inner wall of the gun barrel in a full circumferential rotation to complete the basic cleaning; on the other hand, through the transmission component, it drives the second cleaning component, which is arranged radially along the housing, to rotate around its own axis, and the rotation axis of the second cleaning component is perpendicular to the rotation axis of the first cleaning device, forming a cleaning motion path completely different from that of the first cleaning device. The cleaning motion directions of the two cleaning devices cooperate with each other. The first cleaning device is responsible for a large circumferential coverage, while the second cleaning device, relying on its radial rotation cleaning method, can act on the rifling sidewall area that is difficult to reach circumferentially, using continuous rotational friction to replace the spot sweeping of the traditional circumferential brush, thereby improving the overall cleaning effect.

[0008] Furthermore, the driving device includes a motor and a drive shaft. The motor is fixedly mounted on the housing, and the output end of the motor is fixedly connected to one end of the drive shaft. The drive shaft is arranged along the axial direction of the housing and is used for transmission connection with the first cleaning device and the transmission component, respectively.

[0009] The principle and effect of this solution are as follows: by using the above structure as a unified power source, the power output by the motor is transmitted through the coaxial drive shaft, which can simultaneously provide power for the circumferential revolution of the first cleaning device and the reversing transmission of the transmission components of the second cleaning device. There is no need to set up independent drive units for the two cleaning devices, which reduces the size of the rinsing machine and makes it easy to carry.

[0010] Furthermore, the first cleaning device includes a support plate and an elastic element. The support plate consists of several pieces, all of which are spaced apart along the circumferential direction of the drive shaft. The side of the support plate closest to the drive shaft is fixedly connected to one end of the elastic element, and the other end of the elastic element is fixedly connected to the drive shaft. The side of the support plate opposite to the drive shaft is provided with several bristles.

[0011] The principle and effect of this solution are as follows: when the drive shaft rotates circumferentially, it drives each support plate to rotate synchronously through the elastic element. The bristles on the outer side of the support plate simultaneously clean the circumferential wall of the gun barrel. The elastic element can drive the support plate to expand and contract radially adaptively, which can not only adapt to barrels with different inner diameters, but also automatically compensate for the length after the bristles wear, continuously maintaining the pressure between the bristles and the barrel wall, and can buffer and avoid damage to components caused by the bristles scraping the rifling.

[0012] Furthermore, the second cleaning component includes a brush body and a support shaft; the brush body is rotatably mounted on the housing and is arranged radially along the housing; the side of the brush body near the drive shaft is fixedly connected to one end of the support shaft; the support shaft is used to connect to a transmission component; the side of the brush body away from the drive shaft is provided with a plurality of bristles; the housing is provided with a through hole for the bristles to pass through; the diameter of the through hole is smaller than the maximum outer diameter of the brush body.

[0013] The principle and effect of this solution are as follows: the transmission component drives the brush body to rotate around its own axis through the support shaft. The bristles at the outer end of the brush body extend out of the shell through the through hole and contact the inner wall of the barrel to form a self-rotating cleaning. At the same time, the diameter of the through hole is smaller than the maximum outer diameter of the brush body, which can form a radial limit on the brush body and prevent the brush body from moving outward and falling out.

[0014] Furthermore, the transmission component includes a driven gear and a driving gear. The driven gear is coaxially connected to the support shaft, the driving gear meshes with the driven gear, the rotation axis of the driven gear is perpendicular to the rotation axis of the driving gear, and the driving gear is coaxially fixedly connected to the drive shaft.

[0015] The principle and effect of this solution are as follows: the driving gear rotates synchronously around the housing axis with the drive shaft, and drives the driven gear to rotate in the opposite direction through the vertical meshing transmission relationship. In turn, the second cleaning component rotates around the radial axis through the support shaft, so that there is no need to set up a separate power source for the second cleaning device.

[0016] Furthermore, the second cleaning component also includes a compression component, which abuts against the brush body and the driven gear respectively; the support shaft has a limiting hole, the support shaft passes through the limiting hole, the outer wall of the support shaft has a protrusion along its axial direction, and the limiting hole has a groove that cooperates with the support shaft, so that the support shaft can rotate with the driven gear and can move along its own axis.

[0017] The principle and effect of this solution are as follows: by cooperating with the limiting hole of the driven gear, the circumferential transmission and radial movement of the support shaft can be realized; when the driven gear rotates, the engagement of the groove and the protrusion can transmit torque, drive the support shaft and the brush body to rotate synchronously, and at the same time the support shaft can slide freely along the axis of the limiting hole (radial of the housing). With the elastic force provided by the compression component that abuts between the brush body and the driven gear, the brush body can be pushed to extend radially adaptively. It can automatically compensate for the length after the brush bristles wear, so that the brush bristles are tightly attached to the inner wall of the barrel, and it can be adapted to barrels with different inner diameters.

[0018] Furthermore, there are multiple second cleaning components and driven gears, all of which are spaced apart along the circumferential direction of the drive shaft; there are multiple sets of second cleaning devices, which are arranged sequentially along the axial direction of the drive shaft.

[0019] The principle and effect of this solution are as follows: when the drive shaft is running, multiple circumferentially distributed second cleaning components can simultaneously cover the entire circumferential sidewall of the barrel, while multiple sets of axially arranged second cleaning devices can repeatedly clean the same section of the barrel wall as the device travels along the barrel, thereby improving the cleaning power of the second cleaning devices.

[0020] Furthermore, the first cleaning device is located at the free end of the drive shaft, and the second cleaning device is spaced apart at the rear end of the first cleaning device.

[0021] The principle and effect of this scheme are as follows: the first cleaning device is set at the free end of the drive shaft, that is, the front end of the device, and the second cleaning device is arranged at intervals at its rear end. When the device moves along the barrel, the first cleaning device at the front end contacts the barrel wall first and completes a large-area rough cleaning by relying on circumferential revolution. The second cleaning device at the rear end then follows and performs further cleaning by relying on radial rotation.

[0022] Furthermore, it also includes a feeding device, which includes a worm gear and a worm. The worm is coaxially and fixedly connected to the drive shaft. The worm gear meshes with the worm. There are multiple worm gears, and the multiple worm gears are spaced apart along the circumference of the worm. Each worm gear is coaxially and fixedly connected to a roller. The rotation axis of the roller is rotatably connected to the housing. The housing has a through groove, and the roller passes through the through groove and is located on the outside of the housing.

[0023] The principle and effect of this solution are as follows: when the drive shaft rotates, the worm rotates synchronously. Through the meshing and reversing transmission of the worm gear, multiple worm wheels are driven to rotate, which in turn drives the rollers to rotate synchronously. The rollers pass through the housing groove and abut against the inner wall of the gun barrel. The friction between the rollers and the barrel wall can drive the entire device to move along the gun barrel axis. There is no need to set up an additional independent driving unit, which further reduces the overall size of the device and improves portability.

[0024] Furthermore, the number of the feeding devices is multiple, and they are arranged at intervals along the axial direction of the drive shaft.

[0025] The principle and effect of this solution are: it can support the equipment at multiple points, keeping it centered during movement, preventing the device from tilting or shifting, and ensuring that the bristles fit snugly against the barrel wall. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-6A gun cleaning device according to an embodiment of the present invention is described in detail, comprising a cylindrical housing 1, with a receiving chamber inside the housing 1 for accommodating and mounting a drive device 2, a first cleaning device 3, a second cleaning device 4, and a feeding device 5; wherein, the drive device 2 simultaneously provides power for the circumferential revolution of the first cleaning device 3, the radial rotation of the second cleaning device 4, and the axial crawling of the feeding device 5. The first cleaning device 3 is located at the front end of the housing 1 and is responsible for the basic circumferential cleaning of the inner wall of the gun barrel; the second cleaning devices 4 are arranged axially along the housing 1 at intervals behind the first cleaning devices 3 and are responsible for the fine cleaning of the rifling sidewalls, and the second cleaning devices 4 are all set according to the machining process angle of the barrel rifling, so that the second cleaning devices 4 perform wiping operations along the helical trajectory of the rifling; the feeding device 5 is arranged on the side wall of the housing 1 and is also set according to the machining process angle of the barrel rifling, and is used to drive the entire device to move autonomously along the helical crawling trajectory of the gun barrel. The structure of each device is described in detail below: Please continue reading. Figure 2 and Figure 3 The drive unit 2 includes a motor 21 and a drive shaft 22. The motor 21 is fixedly mounted on the tail end of the housing 1, and its output shaft is coaxially fixedly connected to the tail end of the drive shaft 22 via a coupling. To meet the torque requirements for cleaning and travel, a planetary reducer (not shown) can be connected to the output end of the motor 21. The output hole of the planetary reducer is coaxially fixedly connected to the tail end of the drive shaft 22, and the power is output after the reducer reduces and increases the torque. The drive shaft 22 is set along the entire length of the central axis of the housing 1, and its two ends are respectively rotated with the inner wall of the housing 1 through bearings. The power output by the motor 21 is synchronously transmitted to three devices via the drive shaft 22. The first cleaning device 3 at the front end is directly connected to the free end of the drive shaft 22 to obtain circumferential revolution power; the second cleaning device 4 in the middle section cooperates with the drive shaft 22 through the transmission component 42 to obtain directional rotation power; and the feed device 5 distributed on the shaft cooperates with the drive shaft 22 through a worm gear structure to obtain travel driving force. Using a single motor to drive both cleaning and feeding actions simultaneously eliminates the need for multiple independent drive units, reducing the overall size of the device and improving portability and flexibility in on-site operations.

[0032] Please continue reading. Figure 3 and Figure 4The first cleaning device 3 is located at the free end of the front end of the drive shaft 22, and includes three support plates 31 and three elastic elements 32. The three support plates 31 are evenly spaced along the circumference of the drive shaft 22. Each support plate 31 is an arc-shaped plate adapted to the curvature of the inner wall of the barrel. Multiple bristles are evenly provided on the outer side wall of the support plate facing away from the drive shaft 22. The bristles can be made of wear-resistant nylon or copper wire to meet the cleaning needs of copper plating with different hardness. The inner side wall of each support plate 31 near the drive shaft 22 is fixedly connected to the outer end of the elastic element 32. The other end of the elastic element 32 is fixedly connected to the side wall of the drive shaft 22. In this embodiment, the elastic element 32 is a compression spring, and the spring axis is arranged radially along the housing 1. Furthermore, to better constrain the radial movement trajectory of the support plate 31 and prevent it from deviating, a flange 33 is provided at the front end of the support plate 31. The flange has three positioning grooves 331 along the radial direction. A support rod 34 is connected to the end of the support plate 31. The free end of the support rod 34 is located in the positioning groove 331 and can slide within the positioning groove 331, thereby constraining the movement trajectory of the support plate 31 and preventing it from deviating along the radial direction. During operation, the drive shaft 22 drives all the support plates 31 to revolve synchronously around the axis of the housing 1. The bristles on the outside of the support plate 31 cover the inner wall of the barrel in a full circumference rotation, completing a large-area basic cleaning. The elastic element 32 can adaptively extend and retract radially. On the one hand, it can adapt to barrels with different inner diameter specifications, expanding the applicability of the device. On the other hand, after the bristles wear, the elastic force of the elastic element 32 can push the support plate 31 to move radially outward, automatically compensating for the amount of bristle wear, maintaining the pressure of the bristles against the barrel wall, and the elastic buffer can prevent the bristles from scraping the rifling and reducing damage to the inner wall of the barrel.

[0033] Please continue reading. Figure 2 , Figure 5 and Figure 6The second cleaning device 4 is the core cleaning device of this device, and four sets are provided. The four sets of second cleaning devices 4 are arranged at equal intervals along the axial direction of the drive shaft 22. Each set of second cleaning devices 4 includes multiple transmission components 42 and second cleaning components 41 evenly distributed along the circumference of the drive shaft 22. In this embodiment, each set is provided with 12 second cleaning components 41 to achieve full coverage cleaning of the barrel. The transmission component 42 includes a drive gear 422 and multiple driven gears 421. The drive gear 422 adopts a bevel gear (large bevel gear) structure and is coaxially fixedly mounted on the corresponding shaft section of the drive shaft 22, rotating synchronously with the drive shaft 22 around the housing axis. The driven gears 421 adopt a bevel gear (small bevel gear) structure that meshes with the drive gear 422, and the multiple driven gears 421 are evenly distributed at intervals along the circumference of the drive gear 422. Each driven gear 421 has a mounting hole on the side wall of the housing 1, and the mounting holes are machined at an angle according to the lead angle of the rifling. The driven gear 421 is rotatably assembled in the inclined mounting hole via a bearing, so that the rotation axis of the driven gear 421 is at a fixed angle to the radial direction of the housing 1, matching the rifling lead angle. All driven gears 421 have the same inclination angle and are arranged in a spiral along the circumference, corresponding to the spiral trajectory of the rifling. A limit step is provided on the shaft of the driven gear 421. During assembly, one side of the inner ring of the bearing abuts against the limit step, and the other side of the bearing is axially locked by a clamping retaining ring and a stainless steel retaining ring, ensuring that the driven gear 421 does not move axially during rotation.

[0034] Please continue reading. Figure 2 , Figure 5 and Figure 6The second cleaning component 41 adopts a button brush structure, including a brush body 411, a support shaft 412, and a compression component 413. The brush body 411 is generally cylindrical and button-shaped, arranged radially along the housing 1, with multiple bundles of wear-resistant bristles evenly arranged on its outer end face; a through hole (not shown) is opened on the side wall of the housing 1 corresponding to the position of each brush body 411, and the bristles at the outer end of the brush body 411 can extend through the through hole to the outside of the housing 1 and contact the inner wall of the barrel, and the diameter of the through hole is smaller than the maximum outer diameter of the brush body 411, which can form a radial outward limit on the brush body 411 and prevent the brush body 411 from moving outward and falling out of the housing 1 under the action of elasticity. The center of the inner end face of the brush body 411 is fixedly connected to the outer end of the support shaft 412, which extends radially inward along the housing 1. A limiting hole 423 is opened in the center of the driven gear 421, and the support shaft 412 passes through the limiting hole 423. The support shaft 412 is a square shaft structure, and its outer wall forms a protrusion along its own axial direction. The limiting hole 423 is a corresponding square hole, and the inner wall forms a groove that matches the protrusion. The protrusion and the groove engage with each other to form a transmission structure, so that the support shaft 412 can rotate synchronously with the driven gear 421 in the circumferential direction, and can slide freely along the axial direction of the limiting hole 423 to realize circumferential transmission and radial movement. In this embodiment, the compression member 413 is a compression spring, which is sleeved on the support shaft 412. Its outer end abuts against the inner end face of the brush body 411, and its inner end abuts against the outer end face of the driven gear 421. The compression member 413 is always in a compressed state, continuously applying a radially outward elastic force to the brush body 411, pushing the brush bristles to stick tightly to the inner wall of the gun barrel. When the brush bristles are worn, the compression member 413 automatically pushes the brush body 411 to move radially outward to compensate for the wear. At the same time, this structure can also be adapted to barrels with different inner diameters, improving the versatility of the device.

[0035] Please continue reading. Figure 2 , Figure 5 and Figure 6All the second cleaning components 41 are arranged at an inclined angle matching the rifling lead angle along the radial direction of the housing 1, so that the bristles of the brush body 411 can better fit the helical sidewall of the rifling. Multiple sets of second cleaning devices 4 are also arranged in a staggered axial direction, so that the bristles are distributed along the helical trajectory of the rifling. During operation, the drive gear 422 rotates with the drive shaft 22, driving each driven gear 421 to rotate around the radial axis through bevel gear meshing. This, in turn, drives the brush body 411 to rotate synchronously through the support shaft 412. The bristles at the outer end of the brush body 411 rub against the inner wall of the gun barrel in a radial rotation. Since the rotation axis of the second cleaning component 41 is perpendicular to the rotation axis of the first cleaning device 3, their cleaning motion directions are complementary: the circumferential revolution of the first cleaning device 3 is responsible for covering a large area of ​​the barrel wall to complete rough cleaning, while the radial rotation of the second cleaning component 41 can penetrate deep into the sidewall of the rifling, especially the guide rotation area of ​​the positive rifling, using continuous rotational friction to replace the cleaning of the traditional circumferential brush, facilitating the peeling of the strongly bonded, compacted copper layer. Multiple sets of second cleaning devices 4 are arranged along the axial direction, which can repeatedly clean the same section of the bore wall during the movement of the device, further enhancing the cleaning effect. The inclined arrangement structure allows the device to move smoothly along the rifling trajectory, reducing the hard wear between the bristles and the rifling.

[0036] Please continue reading. Figure 2 and Figure 3The feeding device 5 is the crawling structure of this device. There are two sets of feeding devices 5. The two sets of feeding devices 5 are arranged back and forth along the drive shaft 22 and are located on the front and rear sides of the second cleaning device 4 respectively, forming a multi-point support. Each set of feeding devices 5 includes a worm 52, multiple worm wheels 51 and a corresponding number of rollers 53. The worm gear 52 is coaxially fixedly mounted on the corresponding shaft segment of the drive shaft 22 and rotates synchronously with the drive shaft 22. A through groove 11 is provided on the side wall of the housing 1 corresponding to the position of each group of feed devices 5. The through groove 11 is a gear compartment set according to the machining lead angle of the rifling. The through grooves 11 are evenly distributed along the circumference of the housing 1. In this embodiment, three through grooves 11 are provided in each group. A support shaft (not shown) is provided in each through groove 11. The two ends of the support shaft are rotatably connected to the two side walls of the through groove 11 through bearings, so that the axis of the support shaft and the radial direction of the housing 1 form a fixed tilt angle that matches the rifling lead angle. This angle is consistent with the machining angle of the gear compartment, so that the rolling direction of the roller 53 matches the helical trajectory of the rifling. Each worm gear 51 is coaxially fixedly mounted on a supporting shaft, and the worm gear 51 meshes with the worm 52. Rollers 53 are coaxially fixedly connected to both sides of each worm gear 51. The outer circumferential surface of the rollers 53 is provided with anti-slip and wear-resistant textures. The upper part of the rollers 53 extends through the through groove 11 to the outside of the housing 1, and can abut against the inner wall of the barrel. The opening size of the through groove 11 is adapted to the rotation range of the rollers 53, allowing the rollers 53 to extend normally and contact the barrel wall, and limiting the radial movement of the rollers 53. During operation, the drive shaft 22 drives the worm gear 52 to rotate synchronously. The rotation direction is reversed through the meshing transmission of the worm gear, which drives each worm wheel 51 to rotate, thereby driving the rollers 53 to rotate synchronously. The rollers 53 abut against the inner wall of the gun barrel. Relying on the friction between the rollers 53 and the barrel wall, the entire gun cleaning device can move autonomously at a constant speed along the gun barrel axis. Since the support shaft of the rollers 53 is set at an angle according to the machining angle of the gear box, the rolling direction of the rollers 53 is consistent with the spiral direction of the rifling. Combined with the circumferential rotation trend of the device itself, the entire device crawls along the rifling trajectory in a spiral manner, which can adapt to the rifling structure of the barrel. At the same time, it can ensure that the bristles of the second cleaning device 4 always wipe along the rifling direction, improving the cleaning effect. Meanwhile, by controlling the forward and reverse rotation of the motor 21, the forward and backward movement of the device in the gun barrel can be controlled to achieve reciprocating cleaning operation. The two sets of feed devices 5 are distributed front and rear to form multi-point support, which can keep the device in a centered position in the barrel at all times, avoid tilting or shifting during the movement, and ensure that the bristles can fit against the barrel wall to ensure cleanliness.

[0037] Please continue reading. Figure 1It is also equipped with a control system 6, which is a CNC system. It adopts mature existing technology, such as a servo controller or PLC, and is electrically connected to the motor 21. It can control the start, stop, speed and direction of the motor 21, and can also preset parameters such as cleaning speed, travel speed and number of reciprocating cleaning times to achieve fully automatic cleaning operation and improve the intelligence level of the equipment.

[0038] The overall operation process of this gun cleaning device is as follows: The device is placed in the gun barrel, and the equipment is started after the operating parameters are set by the control system 6. The motor 21 drives the drive shaft 22 to rotate after being reduced by the planetary reducer. The drive shaft 22 outputs three power sources simultaneously: the first power source is transmitted to the first cleaning device 3 at the front end, which drives multiple support plates 31 to rotate circumferentially and perform large-area circumferential coarse cleaning on the inner wall of the gun barrel; the second power source is transmitted to each group of second cleaning devices 4, which drive each button-brush-shaped second cleaning component 41 to rotate along the inclined axis through the meshing and reversal of the large bevel teeth and small bevel teeth, and perform fine friction cleaning on the rifling sidewall, especially the guide side of the positive rim; the third power source is transmitted to the feed device 5, which drives the roller 53 to rotate through the meshing transmission of the worm 52 and the worm wheel 51, and drives the entire device to spiral along the rifling trajectory according to the processing angle of the gear box. During the movement of the device, the first cleaning device 3 at the front end contacts the barrel wall to complete the basic cleaning, while multiple sets of second cleaning devices 4 at the rear follow in sequence, performing a detailed wipe section by section along the rifling spiral path. The two cleaning methods work together to comprehensively cover the concave and convex lines and the guide side area of ​​the barrel inner wall, removing the firmly bonded and compacted copper layer, thus improving the cleaning effect and efficiency. After cleaning is completed, the control system 6 controls the motor 21 to reverse, and the device spirals out of the barrel in the opposite direction along the rifling trajectory. This device can not only be used for cleaning military artillery barrels, but is also suitable for cleaning the inner walls of various industrial pipelines, making it widely applicable.
