Description

Technical Field

[0001] This invention relates to the field of military auxiliary equipment technology, and in particular to a rinsing machine. Background Technology

[0002] During artillery firing, the barrel operates in a high-temperature, high-pressure environment. Propellant residue adheres to the inner wall of the barrel, forming carbon deposits. Because the rifling inside a rifled cannon is spiral, these carbon deposits will adhere to the grooves; if not cleaned promptly, the rifling will wear down during subsequent firings.

[0003] In addition, smoothbore and rifled cannons also leave a large amount of residue inside the barrel during firing, commonly known as "copper residue." These residues, subjected to high temperature and pressure during firing, adhere very firmly to the inner wall of the barrel, especially the residues in the corners of the bore of rifled cannons, which are extremely difficult to remove.

[0004] For a long time, the cleaning and maintenance of smoothbore and rifled cannon barrels in the armies of my country and other countries around the world has mainly been done manually. Recently, a wide variety of barrel cleaning devices have emerged, but due to their low level of automation, incomplete cleaning, and inconvenience in carrying them, their use in the military is limited in number and scope.

[0035] Spray assembly 500, oil spray plate 510, oil spray hole 520, infusion pipe 530. Detailed Implementation

[0036] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] The barrel cleaning machine described in this embodiment relates to the field of military auxiliary equipment technology. This application uses an automated traveling and cleaning device to clean the gun barrel, which has high working efficiency and good cleaning effect.

[0038] Please see Figures 1 to 7 The rinsing machine in this embodiment includes a frame 100, a transmission assembly 200, a drive assembly 300, a rinsing assembly 400, and a spraying assembly 500.

[0039] The transmission assembly 200 includes a drive member 210 connected to one end of the frame 100 and a transmission member 220 arranged across the frame 100. One end of the transmission member 220 is rotatably connected to the drive member 210. The drive member 210 can drive the transmission member 220 to rotate, and the transmission member 220 provides power to the entire rinsing machine.

[0040] The drive assembly 300 is disposed on one side of the frame 100. The drive assembly 300 includes a drive wheel 310 for rolling contact with the bore wall, a mounting bracket 320, and a transmission unit 330. Both ends of the mounting bracket 320 are connected to the frame 100 and the drive wheel 310, respectively. As the drive wheel 310 rolls relative to the bore wall, it drives the frame 100 to move relative to the bore. The mounting bracket 320 can adjust the gap between the drive wheel 310 and the frame 100, allowing the drive wheel 310 to fit snugly against the bore wall, increasing the friction between the drive wheel 310 and the bore wall, and thus enhancing the driving effect of the drive wheel 310. Simultaneously, it can effectively compensate for wear on the drive wheel 310, restoring its driving force. The drive wheel 310 is rotatably connected to the transmission component 220 via the transmission unit 330. The transmission component 220 transmits power to the drive wheel 310 via the transmission unit 330, causing the drive wheel 310 to rotate.

[0041] The breech cleaning assembly 400 includes a breech cleaning brush 410 for cleaning the bore wall. The breech cleaning brush 410 is located at one end of the frame 100 away from the drive member 210 and is rotatably connected to the other end of the transmission member 220. The transmission member 220 can drive the breech cleaning brush 410 to rotate relative to the bore wall, so that the breech cleaning brush 410 can effectively clean the bore wall, remove the deposits on the inner wall of the bore, and restore the performance of the gun.

[0042] The spray assembly 500 includes an oil spray plate 510 disposed between the wiping brush plate 410 and the frame 100. The oil spray plate 510 is fixedly connected to the frame 100, and the oil spray plate 510 is provided with oil spray holes 520 positioned relative to the wiping brush plate 410. The oil spray holes 520 can spray cutting fluid relative to the wiping brush plate 410. In conjunction with the wiping operation of the wiping brush plate 410, the cutting fluid can improve the lubrication performance between the wiping brush plate 410 and the gun barrel, making the rotation of the wiping brush plate 410 smoother. It can also clean oil stains and any rust that may be present in the gun barrel, enhancing the corrosion resistance of the gun barrel.

[0043] In actual use, the cleaning brush 410 is first inserted into one end of the gun barrel and extended inwards, so that the drive wheel 310 contacts the barrel wall. The oil spray plate 510 sprays cutting fluid onto the barrel wall and the cleaning brush 410. The drive component 210 drives the transmission component 220 to rotate. The transmission component 220 first drives the cleaning brush 410 to rotate, cleaning the barrel wall. Simultaneously, the transmission component 220 drives the drive wheel 310 to rotate via the transmission unit 330. The drive wheel 310 drives the entire cleaning machine to move along the inner cavity of the gun barrel. It should be noted that the drive component 210 is specifically a drive motor.

[0044] Please refer to the following for details. Figure 2The transmission component 220 includes at least two transmission parts 221 and a universal coupling 222. Specifically, the transmission component 220 is a transmission shaft, and each transmission part 221 is a segment of the transmission shaft. Adjacent transmission shaft segments are connected by universal couplings. The transmission parts 221 are connected to the transmission unit 330 and the brush plate 410, respectively. The transmission component 220 is connected to two power take-off devices. To accommodate different power take-off devices, the transmission parts 221 may not be concentric. Adjacent transmission shaft segments are connected by universal couplings, which eliminate the negative transmission effects between concentric transmission parts 221, resulting in better overall transmission efficiency of the transmission component 220.

[0045] Please see Figure 3 and Figure 4 The mounting bracket 320 includes a U-shaped portion 321 and a connecting portion 322. The U-shaped portion 321 clamps and rotatably connects to the drive wheel 310. A rotating shaft passes through the drive wheel 310. The U-shaped portion 321 has opposing segments and a junction connecting the two opposing segments. Both ends of the rotating shaft are rotatably connected to the opposing segments via bearings. The drive wheel 310 can rotate relative to the U-shaped portion 321. One end of the connecting portion 322 is fixedly connected to the junction of the U-shaped portion 321, and the other end of the connecting portion 322 passes through the frame body 100 and is screwed onto the frame body 100. The junction of the U-shaped portion 321 abuts against the frame body 100. A groove is provided in the frame body 100 opposite to the junction, and the groove engages with the junction to prevent relative rotation of the U-shaped portion 321, thereby improving the stability of the mounting bracket 320.

[0046] As a further embodiment, a shim is provided between the groove and the junction section. The thickness of the shim can change the gap between the drive wheel 310 and the frame 100, thereby adjusting the tightness of the contact between the drive wheel 310 and the bore wall, enhancing the friction between the drive wheel 310 and the bore wall, and thus enhancing the driving effect of the drive wheel 310. At the same time, after the drive wheel 310 wears, the shim can effectively compensate for the wear of the drive wheel 310 and restore the driving force of the drive wheel 310.

[0047] Please see Figure 3 The transmission unit 330 includes a reducer 331 and a transmission module 332. The reducer 331 is fixedly connected to the frame 100. Specifically, the reducer 331 is a gear reducer. The transmission component 220 is rotatably connected to the input end of the reducer 331. One end of the transmission module 332 is rotatably connected to the output end of the reducer 331. The transmission component 220 transmits torque to the reducer 331. After reducing the speed, the reducer 331 transmits torque to the transmission module 332. The other end of the transmission module 332 is connected to both ends of the shaft of the drive wheel 310, transmitting torque to the drive wheel 310 and driving the drive wheel 310 to rotate.

[0048] As a further implementation, the transmission module 332 is a gear transmission system, a chain transmission system, or a belt transmission system.

[0049] When the transmission module 332 is a gear transmission system, a protective housing is provided between the output end of the reducer 331 and the end of the rotating shaft, and the meshing gears are set in the housing to transmit torque.

[0050] When the transmission module 332 is a chain drive system, the output end of the reducer 331 and the rotating shaft are both equipped with sprockets. The transmission chain is respectively sleeved on the two sprockets, driving the two sprockets to rotate synchronously, thereby realizing the transmission of torque.

[0051] When the transmission module 332 is a belt drive system, pulleys are provided on both the output end and the shaft of the reducer 331. The transmission belt is respectively sleeved on the two pulleys, driving the two pulleys to rotate synchronously and realize the transmission of torque.

[0052] Please see Figure 5 The bore cleaning brush 410 includes a disc body 411 and brush bristles 412. The disc body 411 is rotatably connected to a transmission component 220, which drives the disc body 411 to rotate within the bore. The brush bristles 412 are arranged around the disc body 411 and are detachably connected to the brush. In specific implementation, multiple connecting blocks are arranged around the disc body 411, and the connecting blocks are detachably connected to the disc body 411 by bolts. The brush bristles 412 are arranged radially along the disc body 411 and are fixedly connected to the connecting blocks, with the ends of the brush bristles protruding from the edge of the disc body 411. The brush bristles 412 are generally made of steel wire. The brush bristles 412 can clean the rifling of the bore and remove deposits from the inner wall of the bore, keeping the inner wall of the bore relatively clean. When the brush bristles 412 are damaged due to use, they can be replaced by replacing the connecting blocks, which facilitates the maintenance and replacement of the brush bristles 412.

[0053] Please see Figure 2 and Figure 6A fluid delivery pipe 530 is provided on one side of the frame 100 for connecting to the oil injection plate 510. The fluid delivery pipe 530 is connected to the oil injection hole 520, and can deliver cutting fluid to the oil injection plate 510, continuously supplying cutting fluid to the oil injection plate 510. The fluid delivery pipe 530 is connected to the frame 100 through a bracket, which can fix the fluid delivery pipe 530 and maintain relative stability when the frame 100 moves. As a further embodiment, the oil injection disc 510 has an oil storage chamber in the middle, which is annular. Each oil injection hole 520 is connected to the oil storage chamber. The oil injection holes 520 are equidistantly arranged around the oil injection disc 510 and are radially inclined relative to the oil injection disc 510. The oil injection holes 520 can spray cutting fluid obliquely onto the brush bristles 412 and the bore wall. The cutting fluid can improve the lubrication performance between the wiping brush disc 410 and the bore, making the rotation of the wiping brush disc 410 smoother. It can also clean the oil stains and possible rust in the bore, enhancing the corrosion resistance of the bore.

[0054] Please participate Figure 1 and Figure 7 The frame 100 is equipped with at least two sets of directional wheel groups 110 arranged along the length of the frame 100. The directional wheel groups 110 are spaced apart and include multiple guide wheels 111 for abutting against the bore wall. Each guide wheel 111 is connected to the frame 100 via a bracket and is equidistantly arranged around the frame 100. The guide wheels 111 can abut against the bore wall, ensuring that the frame 100 is always located in the center of the bore and will not shift, thus ensuring that the bore cleaning brush 410 and the fuel injection plate 510 can work normally. In specific implementation, four adjacent guide wheels 111 are arranged vertically. When the frame 100 shifts to one side, the guide wheel 111 on that side will abut against the corresponding bore wall, preventing the frame 100 from shifting excessively.

[0055] The frame 100 is equipped with a load-bearing wheel assembly 120, which is positioned away from the drive wheel 310. The load-bearing wheel assembly 120 includes at least two pairs of oppositely arranged conical wheels 121, spaced apart from each other. The conical wheels 121 are connected to the frame 100 via brackets. The two ends of one conical wheel 121 abut against the bore wall, and the two ends of the opposite conical wheel 121 abut against the bore wall, thus forming a stable load-bearing structure that distributes the force of the frame 100 and its components to both sides, ensuring the relative stability of the rinsing machine. At the same time, the two conical wheels 121 position the rinsing machine, limiting its relative displacement.

[0056] It should be noted that limit switches are provided at both ends of the frame 100. Once the corresponding limit switch is disengaged from the barrel, the limit switch will be triggered. The limit switch controls the drive motor to reverse, which can realize the automatic reciprocating movement of the barrel cleaning machine and prevent the barrel cleaning machine from being disengaged from the barrel and falling out of the barrel, causing unnecessary damage.

[0057] Workflow: First, the cleaning brush 410 is inserted into one end of the barrel and extends inward to bring the drive wheel 310 into contact with the barrel wall. The guide wheel 111 and the conical wheel 121 both abut against the barrel wall to ensure the stability of the frame 100. The oil spray plate 510 sprays cutting fluid from the oil spray hole 520 onto the barrel wall and the cleaning brush 410. The drive component 210 drives the transmission component 220 to rotate. The transmission component 220 first drives the cleaning brush 410 to rotate, cleaning the barrel wall. Simultaneously, the transmission component 220 drives the drive wheel 310 to rotate via the transmission unit 330, and the drive wheel 310 drives the entire cleaning machine to move along the inner cavity of the barrel.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of the present invention.
