Description

Technical Field

[0001] This utility model relates to the field of gun barrel cleaning technology, and in particular to a gun barrel cleaning device. Background Technology

[0002] As a key load-bearing component of the tank artillery firing system, the condition of the inner wall surface of the tank barrel directly determines the firing accuracy, range, and service life of the gun. During combat and training, the barrel must withstand high temperatures, high pressures, and high-speed friction from projectiles. If contaminants are present on the inner wall, it will lead to uneven force on the projectile, reduced rifling efficiency, and consequently, firing deviations. In severe cases, the accumulation of contaminants can even cause projectile jamming or barrel explosions. Therefore, barrel cleaning is a core aspect of tank equipment maintenance, directly impacting the equipment's combat effectiveness and operational safety.

[0003] When ammunition is fired, the combustion of gunpowder produces solid residue, liquid condensate, and gaseous impurities. Among these, solid residue tends to adhere to the rifling grooves and beveled areas, while liquid condensate reacts chemically with the inner metal walls to form complex dirt that is difficult to remove.

[0004] Currently, the cleaning process is mainly achieved through a combination of a cleaning rod and a cleaning head. During operation, the cleaning rod and the cleaning head need to be manually inserted into the barrel and moved back and forth along the barrel axis to achieve the cleaning process. This is inefficient, requires at least two people to operate, and the cleaning effect is also poor. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a cannon barrel cleaning device. This device is lightweight and compact, can move independently back and forth inside the cannon barrel, has simplified operation and control, can be easily handled by any operator, and can be installed as part of any equipment. At the same time, its functionality and flexibility enable it to clean any cannon barrel with good cleaning effect.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A gun barrel cleaning device includes a cylinder that can be inserted into a gun barrel. Multiple pairs of extendable travel arms are embedded in the circumferential wall of the cylinder. A pair of rollers are installed at the ends of each travel arm. A drive assembly for rotating the rollers is installed inside each travel arm. An axially extendable tube shaft is installed inside the cylinder. Both ends of the tube shaft extend out of the cylinder and are detachably fitted with brush discs. An internal control line and an internal water pipe are integrated inside the tube shaft. The drive assembly is electrically connected to the internal control line. The rear ends of the internal control line and the internal water pipe extend out of the rear end of the tube shaft and are respectively connected to an external control line and an external water pipe. The circumferential sidewall of the brush disc has multiple water outlet holes that cooperate with the internal water pipe.

[0007] Preferably, the drive assembly includes a transmission head fixedly mounted at the end of the walking arm, an axle rotatably connected between a pair of rollers, a first motor installed inside the walking arm, the output end of the first motor extending into the transmission head, and the output end being connected to the axle via a bevel gear pair.

[0008] Preferably, the circumferential sidewall of the cylinder is provided with a spring outlet for the corresponding traveling arm to pop out. One end of the traveling arm located inside the cylinder is rotatably connected to the cylinder via a support arm shaft, and a torsion spring is fitted on the support arm shaft.

[0009] Preferably, a second motor is installed inside the rear end of the cylinder, a cam is fixed at the output end of the second motor, a stop plate that abuts the cam is fixedly sleeved on the tube shaft, the stop plate is slidably installed inside the cylinder, and springs are elastically connected between the inner walls of both sides of the cylinder and the stop plate.

[0010] Preferably, both ends of the tube shaft are provided with external threads, the center of the brush disk is provided with a mounting hole, the inner side of the mounting hole is provided with an internal thread adapted to the external thread, and the two ends of the tube shaft are also fixed with limiting plates to restrict the installation position of the brush disk.

[0011] Preferably, the rear end of the inner water pipe is connected to the outer water pipe via a threaded joint, and the rear end of the inner control line is connected to the outer control line via an aviation joint.

[0012] Preferably, the circumferential inner wall of the mounting hole is provided with an annular water groove, and sealing rings that abut against the pipe shaft are embedded at both sides of the groove opening of the annular water groove. The multiple circumferential water outlets are all connected to the annular water groove. The side wall of the inner water pipe is provided with a water inlet pipe that extends to the outer wall of the pipe shaft, and the water inlet pipe is connected to the annular water groove.

[0013] Preferably, the circumferential sidewall of the brush disk is evenly distributed with multiple nylon brush heads.

[0014] Preferably, the tube shaft is provided with a low-friction thread on the front section inside the cylinder, and a non-self-locking helical pair is threaded onto the low-friction thread. A turntable is fixedly sleeved on the non-self-locking helical pair. The circumferential sidewall of the turntable is rotatably connected to the inner wall of the cylinder and is fitted with an inner magnetic ring. An annular oil reservoir is sleeved on the outer wall of the front end of the cylinder. An outer magnetic ring that magnetically attracts the inner magnetic ring is embedded in the inner wall of the annular oil reservoir. The circumferential sidewall of the annular oil reservoir is provided with multiple oil outlet holes, and the annular oil reservoir is filled with rust-preventive oil.

[0015] The beneficial effects of this utility model are as follows: 1. By installing the cylinder, detachable brush discs, and tube shaft, select a pair of brush discs suitable for the diameter of the barrel and screw them to both ends of the tube shaft. After screwing them to the limit position against the limiting plate, connect the external water pipe to the internal water pipe through a threaded connector, and connect the external control line to the internal control line through an aviation connector. Insert the cylinder into the barrel. Multiple pairs of traveling arms, under the action of torsion springs, make the rollers contact the inner wall of the barrel. The external control line is connected to an external controller and powered. The first motor starts, driving the rollers to rotate through the bevel gear pair, driving the cylinder forward or backward, and thus driving the brush discs to move inside the barrel to complete the cleaning process. The device is lightweight and compact, and can move back and forth independently inside the barrel. The operation and control are simplified, and any operator can easily handle it. It can also be installed as part of any equipment. At the same time, its functionality and flexibility can clean any barrel, with high cleaning efficiency and good effect.

[0016] 2. By installing an external water pipe, an internal water pipe, an annular water tank, and a water outlet, the second motor is started to drive the cam to rotate. The abutment plate, under the action of the spring, always contacts the cam, thereby driving the tube shaft to move back and forth, and finally driving the front and rear brush plates to move back and forth. The nylon brush head wipes the contaminants on the inner wall of the barrel. At the same time, the external water pipe pumps cleaning agent into the internal water pipe, and then pumps it into the annular tank through the water inlet pipe. Finally, it is sprayed into the barrel through multiple water outlets, working with the brush plates to complete the brushing process. After completing multiple front and rear brushing processes, the barrel is removed, non-woven fabric is wrapped around the brush plates, and then stuffed back into the barrel to complete the water absorption process. Alternatively, a hot air blower can be connected to the external water pipe to achieve the drying process of the barrel. This effectively washes away stubborn contaminants on the inner wall and wipes and dries the moisture in time to prevent rust.

[0017] 3. By setting up a low-friction thread, a non-self-locking screw pair, a turntable, an inner magnetic ring, an outer magnetic ring, and an annular oil reservoir, the annular oil reservoir filled with rust-preventive oil is fitted onto the front end of the cylinder. The cylinder is then inserted into the barrel. During the reciprocating movement of the tube shaft, the low-friction thread and the non-self-locking screw pair work together to drive the turntable to rotate. Under the magnetic attraction of the inner and outer magnetic rings, the annular oil reservoir rotates. Under the action of centrifugal force, the rust-preventive oil is thrown out through the oil outlet and sprayed onto the inner wall of the barrel. With the help of the brush, the oil is evenly applied, thus achieving the barrel maintenance process. Attached Figure Description

[0022] Reference Figure 1-4 A cannon barrel cleaning device includes a cylinder 1 that can be inserted into a cannon barrel. Multiple pairs of pop-out walking arms 2 are embedded in the circumferential wall of the cylinder 1. A pair of rollers 4 are installed at the end of each walking arm 2. A drive assembly for driving the rollers 4 to rotate is installed inside the walking arm 2. The drive assembly includes a transmission head 3 fixedly installed at the end of the walking arm 2. An axle is rotatably connected between the pair of rollers 4. A first motor 23 is installed inside the walking arm 2. The output end of the first motor 23 extends into the transmission head 3. The output end is connected to the axle through a bevel gear pair 24. A pair of brush discs 6 that are suitable for the diameter of the cannon barrel are selected and screwed to both ends of a tube shaft 8, which can clean any cannon barrel.

[0023] Furthermore, the circumferential sidewall of the cylinder 1 is provided with a projectile outlet 5 for the corresponding traveling arm 2 to be ejected. One end of the traveling arm 2 located inside the cylinder 1 is rotatably connected to the cylinder 1 through the arm shaft 16. A torsion spring is fitted on the arm shaft 16. Under the action of the torsion spring, multiple pairs of traveling arms 2 make the roller 4 always abut against the inner wall of the barrel.

[0024] A retractable tube shaft 8 is installed inside the cylinder 1. A second motor is installed inside the rear end of the cylinder 1. A cam 11 is fixed to the output end of the second motor. A stop plate 9 that abuts against the cam 11 is fixedly sleeved on the tube shaft 8. The stop plate 9 is slidably installed inside the cylinder 1. Springs 10 are elastically connected between the inner walls on both sides of the cylinder 1 and the stop plate 9. When the second motor is started, the cam 11 is driven to rotate. The stop plate 9 always abuts against the cam 11 under the action of the spring 10, thereby driving the tube shaft 8 to move back and forth. Finally, it drives the front and rear brush plates 6 to move back and forth, and wipes the contaminants on the inner wall of the barrel with nylon brush heads.

[0025] Both ends of the tube shaft 8 extend out of the cylinder 1 and are detachably mounted with brush discs 6. Multiple nylon brush heads are evenly distributed on the circumferential sidewalls of the brush discs 6. Both ends of the tube shaft 8 are provided with external threads 17. The center of the brush discs 6 is provided with mounting holes 7. The inner side of the mounting holes 7 is provided with internal threads that are adapted to the external threads 17. The two ends of the tube shaft 8 are also fixed with limiting plates 15 to restrict the installation position of the brush discs 6.

[0026] The tube shaft 8 integrates an internal control line 20 and an internal water pipe 21. The drive component is electrically connected to the internal control line 20. The rear ends of the internal control line 20 and the internal water pipe 21 extend out of the rear end of the tube shaft 8 and are respectively connected to the external control line 13 and the external water pipe 12. The rear end of the internal water pipe 21 is connected to the external water pipe 12 through a threaded joint 22, and the rear end of the internal control line 20 is connected to the external control line 13 through an aviation joint, making disassembly and assembly convenient.

[0027] The brush plate 6 has multiple water outlet holes 14 on its circumferential sidewalls that mate with the inner water pipe 21. The mounting hole 7 has an annular water groove 19 on its circumferential inner wall. Sealing rings 18 that abut against the tube shaft 8 are embedded at both sides of the groove opening of the annular water groove 19. The multiple water outlet holes 14 are all connected to the annular water groove 19. The inner water pipe 21 has an inlet pipe 32 extending to the outer wall of the tube shaft 8 on its sidewalls. The inlet pipe 32 is connected to the annular water groove 19. The outer water pipe 12 pumps cleaning agent into the inner water pipe 21, and then pumps it into the annular groove 19 through the inlet pipe 32. Finally, it is sprayed into the barrel through the multiple water outlet holes 14, thus cooperating with the brush plate 6 to achieve the brushing process.

[0028] The cleaning steps are as follows: Select a pair of suitable brush discs 6 according to the diameter of the barrel, screw them to both ends of the tube shaft 8, and screw them to the limit position of the contact limit plate 15. Then connect the outer water pipe 12 to the inner water pipe 21 through the threaded joint 22, and connect the outer control line 13 to the inner control line 20 through the aviation joint.

[0029] The cylinder 1 is inserted into the barrel. Multiple pairs of traveling arms 2, under the action of torsion springs, cause the rollers 4 to contact the inner wall of the barrel. The external control line 13 is connected to an external controller and powered. The first motor 23 starts and drives the rollers 4 to rotate through the bevel gear pair 24, which drives the cylinder 11 to move forward or backward, and in turn drives the brush 6 to move inside the barrel.

[0030] The second motor is started, which drives the cam 11 to rotate. The abutment plate 9 is always in contact with the cam 11 under the action of the spring 10, which in turn drives the tube shaft 8 to move back and forth, and finally drives the front and rear brush plates 6 to move back and forth. The nylon brush head wipes the pollutants on the inner wall of the barrel. At the same time, the outer water pipe 12 pumps the cleaning agent into the inner water pipe 21, and then pumps it into the annular groove 19 through the water inlet pipe 32. Finally, it is sprayed into the barrel through multiple water outlets 14, which works with the brush plates 6 to achieve the washing process.

[0031] After completing multiple front and back brushing processes, remove the cylinder 1, wrap the non-woven fabric around the brush plate 6, and stuff it back into the barrel to achieve the water absorption process. Alternatively, the external water pipe 12 can be connected to a hot air blower to achieve the drying process of the barrel. Example 2

The annular oil storage tank 25 filled with rust-preventive oil is fitted onto the front end of the cylinder 1. The cylinder 1 is then inserted into the barrel. During the reciprocating movement of the tube shaft 8, the low-friction thread 27 and the non-self-locking screw pair 28 cooperate to drive the turntable 31 to rotate. Under the magnetic attraction of the inner magnetic ring 30 and the outer magnetic ring 29, the annular oil storage tank 25 is driven to rotate. Under the action of centrifugal force, the rust-preventive oil is thrown out through the oil outlet 26 and sprayed onto the inner wall of the barrel. With the help of the brush 6, it is evenly applied, completing the barrel maintenance process.
