[0015] Preferably, a plurality of groups of nozzles are arranged through the cleaning housing at equal intervals along its circumferential direction.

[0016] According to the above technical solution, the beneficial effects of the intelligent gun barrel cleaning machine provided by the present invention during use are: (1) Since the driving shaft of the power mechanism is respectively connected to each set of brushes of the first cleaning mechanism, each set of brushes on the first cleaning mechanism can rotate and clean the inner wall of the gun barrel while rotating. At the same time, the end of the driving shaft is assembled with the second cleaning mechanism so that the driving shaft drives the second cleaning mechanism to rotate together, thereby enabling the second cleaning mechanism to perform a rotational wiping and cleaning of the inner wall of the gun barrel.

[0017] Therefore, since the first cleaning mechanism and the second cleaning mechanism have different cleaning methods, they can be used in conjunction with each other to clean the inner wall of the barrel more highly and comprehensively, thereby improving the cleaning effect.

[0018] (2) Since the walking mechanism and the power mechanism are also connected together by transmission, during the cleaning process, one power mechanism can provide power to multiple mechanisms at the same time, without the need for multiple power sources to drive each mechanism separately, which saves the use cost and reduces the size of the barrel cleaning machine, making it easy to carry.

[0019] (3) However, since the brush body of the existing cleaning mechanism is worn out during long-term use, it cannot fully fit with the inner wall of the gun barrel, resulting in poor cleaning effect in the later stage. However, in the present application, when the brush body of the cleaning mechanism is worn out during long-term use and cannot fit or fully contact with the inner wall of the gun barrel, the first automatic adjustment mechanism and the second automatic adjustment mechanism can automatically adjust the brush body of each cleaning mechanism to always be against the inner wall of the gun barrel to ensure its cleaning effect. Therefore, the cleaning mechanism provided by the present application overcomes the problem of the existing technology that the brush body is worn out during long-term use, thereby reducing the cleaning effect.

[0020] (4) During use, since some gun barrels have spiral tracks on their inner walls, all the rotating brushes on the cleaning shell of the present application are arranged in multiple rows of rotating brushes that are inclined along the circumferential direction of the cleaning shell, and the gap between each two adjacent rows of rotating brushes matches the track of the gun barrel, so that each two adjacent rows of rotating brushes can be stuck on the track, so that the cleaning mechanism can move and wipe along the rifling track. The cleaning mechanism can achieve the best wiping effect when it moves along the rifling track, and at the same time, it will not cause damage to the brush body of the cleaning mechanism and the running wheels of the running mechanism, thus achieving high wiping efficiency and extending its service life.

[0021] In summary, the present invention uses a driving mechanism and a cleaning mechanism to clean the inner wall of the gun barrel in different ways to improve the cleaning efficiency, and can also provide driving force for the walking mechanism, playing multiple roles, and can automatically adjust the brush bodies of the two respectively through the automatic adjustment mechanism, so that the brush body always rests on the inner wall of the gun barrel, thereby overcoming the problem of the existing technology that the brush body is worn during long-term use and the cleaning effect is reduced.

Detailed description of the specific implementation mode

[0025] The following will describe the specific implementation mode of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation mode described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] As Figure 1-16 shown, an intelligent gun barrel cleaning machine provided by the present invention includes: a cleaning mechanism, a traveling mechanism 4 provided on the cleaning mechanism, and a power mechanism 1 respectively connected to the cleaning mechanism and the traveling mechanism 4 to provide power for both; The cleaning mechanism includes: a first cleaning mechanism 2 and a second cleaning mechanism 3; The first cleaning mechanism 2 includes: a cleaning housing 201 and a plurality of sets of rotatable brushes that are arranged at equal intervals along the axial length of the cleaning housing 201 and are movably disposed thereon and are in transmission connection with the transmission mechanism 1. A first automatic adjustment mechanism is provided on each brush, so that each set of brushes can rotate and move in the radial direction of the cleaning housing 201 to adjust the distance between all the brushes on it and the inner wall of the gun barrel, so that each set of brushes abuts against the inner wall of the gun barrel. The power mechanism 1 and the second cleaning mechanism 3 are respectively assembled at both ends of the cleaning housing 201. The drive shaft 103 of the power mechanism 1 is coaxially and rotatably assembled inside the cleaning housing 201, and the free end of the drive shaft 103 passes out of the inside of the cleaning housing 201 and is assembled and connected with the second cleaning mechanism 3 to drive the second cleaning mechanism to rotate along the inner wall of the gun barrel for cleaning. A second automatic adjustment mechanism is provided on the second cleaning mechanism 3 to adjust the distance between the brush body on it and the inner wall of the gun barrel, so that the brush body on it can always abut against the inner wall of the gun barrel.

[0027] In the above solution, during use, since the drive shaft 103 of the power mechanism 1 is respectively in transmission connection with each set of brushes of the first cleaning mechanism 2, so that each set of brushes on the first cleaning mechanism 2 can rotate and clean the inner wall of the gun barrel while rotating. At the same time, the end of the drive shaft 103 is assembled with the second cleaning mechanism 3, so that the drive shaft 103 drives the second cleaning mechanism 3 to rotate together, so that the second cleaning mechanism 3 performs rotary wiping and cleaning on the inner wall of the gun barrel.

[0028] Therefore, due to the different cleaning methods of the first cleaning mechanism 2 and the second cleaning mechanism 3, through the combined use of the two, the inner wall of the gun barrel can be cleaned higher and more comprehensively, improving the cleaning effect.

[0029] In addition, since the traveling mechanism 4 is also in transmission connection with the power mechanism 1, during the cleaning process, one power mechanism 1 can provide power for multiple mechanisms at the same time, without multiple powers to drive each mechanism separately, saving the use cost and reducing the volume of the gun barrel cleaning machine, which is convenient to carry.

[0030] In addition, when the existing cleaning mechanism is used for a long time, after the brush body on it is worn, it cannot fit well with the inner wall of the gun barrel, resulting in poor cleaning effect in the later stage. During the use of the present application, when the cleaning mechanism is used for a long time and the brush body on the brush tool is worn and cannot fit or make full contact with the inner wall of the gun barrel, at this time, the first automatic adjustment mechanism and the second automatic adjustment mechanism can automatically adjust the brush body of each cleaning mechanism to always abut against the inner wall of the gun barrel to ensure its cleaning effect. Therefore, the cleaning mechanism provided by the present application overcomes the problem that the cleaning effect is reduced due to the wear of the brush body during long-term use in the prior art.

[0031] The traveling mechanism 4 can drive the cleaning mechanism to reciprocate in the gun barrel, the operation process is simple, the manual pushing of the brush is reduced, the labor force is reduced, and the wiping efficiency of the inner wall of the gun tube is improved.

[0032] In addition, the use of this intelligent gun barrel cleaning machine is not limited to the gun barrels of the military, but can also be applied to the cleaning of the inner walls of pipes in other fields such as water pipes or sewage pipes used in daily life or sewage treatment.

[0033] In a preferred embodiment of the present invention, each set of brush tools includes: a rotary brush 202, a small bevel gear 203 and a large bevel gear 204; wherein, A plurality of large bevel gears 204 are coaxially and fixedly arranged at equal intervals along the axial direction of the drive shaft 103 located inside the cleaning housing 201, and a small bevel gear 203 meshing with the large bevel gear 204 is penetrated and rotatably arranged on the side wall of the cleaning housing 201 along the circumferential direction of each large bevel gear 204, and a rotary brush 202 is movably arranged at the end of each small bevel gear 203 located outside the cleaning housing 201 through a first automatic adjustment mechanism, and a plurality of brush bodies are uniformly fixed at the end of each rotary brush 202.

[0034] In the above solution, as shown in the figure, the cleaning housing 201 is provided with bearing holes for each small gear 203 to pass through, so as to facilitate the assembly of the rotary brush 202, and each small bevel gear 203 can be rotatably assembled on the cleaning housing 201 through bearings.

[0035] In addition, during the use process, since there are spiral tracks on the inner wall of some gun barrels, such as Figure 1-6As shown, all the rotary brushes 202 of the cleaning housing 201 described in the present application are arranged in multiple inclined rows along the circumferential direction of the cleaning housing 201, and the gaps between every two adjacent rows of rotary brushes 202 match the track of the gun barrel, so that every two adjacent rows of rotary brushes 202 can be stuck on the track, so that the cleaning mechanism can walk along the rifling track and wipe. The cleaning mechanism can achieve the best wiping effect only along the rifling track. At the same time, it will not cause damage to the brush body of the cleaning mechanism and the walking wheels 403 of the walking mechanism 4. The wiping efficiency is high and its service life is extended.

[0036] In a preferred embodiment of the present invention, the first automatic adjustment mechanism includes: a convex portion 6, a hexagon wave bead screw 7, and a first tension spring 8; wherein, In the middle of each rotary brush 202 facing away from the brush body, a convex portion 6 protrudes outward partially, and at the end of the rotating shaft of each small bevel gear 203, a slot is formed by inward depression partially for cooperating with the convex portion 6. The convex portion 6 can be inserted into the slot, and a hexagon wave bead screw 7 perpendicular to it is detachably assembled on the side wall of each convex portion 6. At least a guiding strip hole 9 communicating with the slot and adapted to the hexagon wave bead screw 7 is formed on the side wall of the rotating shaft of each small bevel gear 203, so that the hexagon wave bead screw 7 on the convex portion 6 inserted into the slot can partially pass through the guiding strip hole 9 and move along its length direction. A first tension spring 8 is sleeved on the convex portion 6 located between the slot and the rotary brush 202, and both ends of the first tension spring 8 are fixed on the rotary brush 202 and the small bevel gear 203 respectively.

[0037] In the above solution, as Figure 7-9 shown, with the cooperation of the guiding strip hole 9 of the small bevel gear 203 and the hexagon wave bead screw 7 of the rotary brush 202, the rotary brush 202 can be made to move along the axial direction of the small bevel gear 203 (that is, along the radial direction of the cleaning housing 201). Under the tension force of the first tension spring 8, the rotary brush 202 moves away from the cleaning housing 201 along the radial direction of the cleaning housing 201 through the hexagon wave bead screw 7 and abuts against the inner wall of the gun barrel, so that the rotary brush 202 can always abut against the inner wall of the gun barrel to ensure that during the cleaning process of the first cleaning mechanism 2, its brush can always abut against the inner wall of the gun barrel to ensure its cleaning effect.

[0038] When the brush body on the rotary brush 202 is worn and the length of the brush body becomes short, under the tension of the first tension spring 8, the rotary brush 202 can be driven to move away from the cleaning housing 201 along the radial direction of the cleaning housing 201 and abut against the inner wall of the gun barrel in cooperation with the hexagonal wave bead screw 7 and the guiding strip-shaped hole 9, so as to realize the function of automatic adjustment, ensure the cleaning effect of the first cleaning mechanism 2, and also extend its service life.

[0039] The present application also provides another assembly method of the small bevel gear 203, but not limited to this assembly method. The specific assembly method is that a bearing hole for assembling the small bevel gear 203 is provided on the cleaning housing 201. First, the bearing is assembled in the assembly shaft hole on the cleaning housing 201, and then when the bearing is assembled on the small bevel gear 203, as Figure 9 shown, a limiting step is provided on the circumference of the small bevel gear 203, which is used to limit one side of the bearing during the assembly of the bearing. Specifically, the bearing is sleeved on the circumference of the small bevel gear 203 so that one side of the bearing abuts against the limiting step. A clamping retaining ring is assembled on the shaft body of the small bevel gear 203 on the other side of the bearing, and a stainless steel hole retaining ring is assembled on the outside of the clamping retaining ring, so that the stainless steel hole retaining ring is coaxially assembled on the clamping retaining ring and used in cooperation with it. Therefore, through the cooperation of the limiting step on the small bevel gear 203, the stainless steel hole retaining ring and the clamping retaining ring, both sides of the bearing assembled in the bearing hole are limited to prevent the bearing from moving along the hole direction in the bearing hole. In addition, a washer with both sides respectively abutting against the bearing and the stainless steel hole retaining ring is also assembled between the bearing and the stainless steel hole retaining ring.

[0040] Through the above assembly method, the bearing for assembling the small bevel gear 203 can be fixed in the bearing hole on the cleaning housing 201.

[0041] In a preferred embodiment of the present invention, the second cleaning mechanism 3 includes a cleaning seat 301, a brush plate 302 and a hexagonal head screw 303; wherein, A plurality of arc-shaped brush plates 302 that are adjustable along the radial direction of the cleaning housing 201 are arranged at equal intervals and movably on the outer wall of the cleaning seat 301 along the circumferential direction of the cleaning housing 201 through a second automatic adjustment mechanism. A plurality of brush bodies are uniformly fixed on the surface of the brush plate 302 facing away from the hexagonal head screw 303. A through hole for cooperating with the hexagonal head screw 303 is formed through the middle of the cleaning seat 301. A threaded groove for cooperating with the hexagonal head screw 303 is formed by the inward depression of the free end of the driving shaft 103. The hexagonal head screw 303 passes through the top of the cleaning seat 301 and is threadedly fixed in the threaded groove of the driving shaft 103.

[0042] In the above solution, as Figure 10-11 shown, the hexagon socket head screw 303 is inserted into the cleaning base 301 from the top and passes through its bottom and then screwed onto the end of the drive shaft 103, so that during the rotation of the drive shaft 103, the cleaning base 301 and multiple brush plates 302 assembled thereon can be driven to rotate together to clean the inner wall of the gun barrel, and the drive shaft 103 provides cleaning power for the second cleaning mechanism 3.

[0043] In addition, since each brush plate 302 can move along the radial direction of the cleaning housing 201 towards the inner wall of the gun barrel through the second automatic adjustment mechanism until the brush body of each brush plate 302 abuts against the inner wall of the gun barrel, to ensure that during the cleaning process of the second cleaning mechanism 3, its brush body can always abut against the inner wall of the gun barrel to ensure its cleaning effect. This avoids the problem in the prior art that during long-term use, the brush body wears out and cannot contact the inner wall of the gun barrel, resulting in incomplete cleaning and reduced cleaning effect.

[0044] In a preferred embodiment of the present invention, the cleaning base 301 includes: an end cover 3011 and a drive flange 3012; wherein, One-way through holes and two-way through holes for the hexagon socket head screw 303 to pass through are respectively provided in the middle parts of the end cover 3011 and the drive flange 3012 that are spaced apart and arranged in parallel, and a first drive sleeve 10 and a second drive sleeve 11 that are used in cooperation with each other are coaxially and fixedly provided at the one-way through holes and two-way through holes on their facing surfaces respectively. A plurality of card slots are provided at equal intervals along the circumferential direction at the end of the second drive sleeve 11, and a plurality of card blocks that are used in cooperation with the plurality of card slots are formed by protruding outward at equal intervals along the circumferential direction at the end of the first drive sleeve 10. The hexagon socket head screw 303 passes through the first drive sleeve 10 of the end cover 3011 and the second drive sleeve 11 of the drive flange 3012 in sequence and is screwed onto the drive shaft 103.

[0045] In the above solution, as Figure 11 shown, during assembly, a plurality of card blocks on the first drive sleeve 10 on the end cover 3011 are inserted into a plurality of card slots on the second drive sleeve 11 on the drive flange 3012, and the hexagon socket head screw 303 is inserted into the one-way through hole at the top of the end cover 3011, passes through the first drive sleeve 10 and the second drive sleeve 11, passes through the drive flange 3012, and is finally screwed onto the drive shaft 103.

[0046] In addition, the drive flange 3012 is assembled on the end of the cleaning housing 201 through a plain bearing.

[0047] During use, under the cooperation of a plurality of clamping blocks on the first drive sleeve 10 on the end cap 3011 and a plurality of card slots on the second drive sleeve 11 on the drive flange 3012, the drive shaft 103 can drive the end cap 3011, the drive flange 3012, and a plurality of brush plates 302 assembled between the two to rotate during the rotation process.

[0048] In a preferred embodiment of the present invention, the second automatic adjustment mechanism includes: a guide rod 13, a guide slider 14, and a second tension spring 15; wherein, A plurality of assembly grooves 12 for assembling a plurality of brush plates 302 are respectively formed at equal intervals along the circumferential direction of the end cap 3011 and the drive flange 3012. A guide rod 13 is horizontally and fixedly arranged in each assembly groove 12. Guide sliders 14 for cooperating with the respective corresponding guide rods 13 are respectively fixedly arranged in the middle parts of the upper and lower ends of each brush plate 302. The two guide sliders 14 of each brush plate 302 are respectively slidably assembled on the two guide rods 13 on the end cap 3011 and the drive flange 3012. A second tension spring 15 perpendicular to the hexagon socket head screw 303 is assembled on each brush plate 302 facing away from the brush body. The other end of each second tension spring 15 is assembled on the first drive sleeve 10 or the second drive sleeve 11.

[0049] In the above solution, as Figure 10 and 11 shown, through the cooperation of the guide rod 13 and the guide slider 14 on the brush plate 302, a guiding effect is achieved, so that each brush plate 302 can move along the radial direction of the cleaning housing 201 or the drive shaft 103.

[0050] In the above solution, under the action of the tension force of the second tension spring 15, each brush plate 302 can move along the radial direction of the drive shaft 103 or the cleaning housing 201 toward the inner wall of the gun barrel through the guide slider 14 on the guide rod 13, so that the brush body on the brush plate 302 always abuts against the gun barrel.

The two ends of each second tension spring 15 are respectively clamped in the corresponding first positioning hole 16 and second positioning hole 17.

[0052] In the above solution, the corresponding and cooperating first positioning hole 16 and second positioning hole 17 are used to limit the second tension spring 15.

[0053] Of course, both ends of each second tension spring 15 can also be directly fixed to the corresponding and cooperating brush plate 302 and the first drive sleeve 10 or the second drive sleeve 11 respectively.

A plurality of assembly openings are equidistantly and rotatably arranged on the traveling seat along the circumferential direction of the worm 401, and a rotating shaft is rotatably arranged in each assembly opening. A worm gear 402 meshingly connected with the worm 401 is coaxially fixedly arranged on each rotating shaft, and traveling wheels 403 are coaxially fixedly arranged on the rotating shafts on both sides of the worm gear 402 respectively.

[0055] In the above solution, since each worm 401 is sleeved and fixed on the drive shaft 103, when the drive shaft 103 rotates, all the worms 401 can be driven to rotate together. When each worm 401 rotates, all the worm gears 402 meshingly connected with it can be driven to rotate, and when each worm gear 402 rotates, all the traveling wheels 403 coaxial with it can be driven to travel.

[0056] In addition, when each worm 401 and the multiple worm gears 402 meshingly connected with it are assembled, each corresponding worm gear 402 is obliquely assembled on the cleaning housing 201, and the assembly angle between the worm 401 and each corresponding worm gear 402 is 7.5°, so as to cooperate with the rotary brush 202 on the cleaning housing 201 to run and clean along the trajectory of the rifling.

[0057] The present application provides an assembly method of the large bevel gear 204, the worm 401 and the drive shaft 103, but is not limited to this assembly method. The assembly method is as follows: Such as Figure 12-16As shown, on the shaft body of the drive shaft 103, first keys that cooperate with all the large bevel gears 204 are fixedly arranged at equal intervals along the axial direction of the shaft body. And on the inner diameter of each large bevel gear 204, a first keyway that cooperates with the first key is partially recessed inward. All the large bevel gears 204 are respectively slidably assembled on all the first keys through the first keyways inside them. And a spacing sleeve is coaxially sleeved between every two adjacent large bevel gears 204 to equally space all the large bevel gears 204 apart. And on the inner diameter of each spacing sleeve, a first keyway that cooperates with the first key is also partially recessed inward. On the shaft body of the drive shaft 103 at both ends of a row of large bevel gears 204, second keys that cooperate with two worm gears 401 are respectively fixedly arranged. And on the inner diameters of the two worm gears 401, second keyways that cooperate with the second keys are respectively partially recessed inward. And the two worm gears 401 are slidably assembled on the two second keys through the second keyways (the length of the second key is greater than the length of the first key, and the width, thickness of the second key are the same as those of the first key). And a distance sleeve is also assembled between each worm gear 401 and its adjacent large bevel gear 204. And on the shaft body of the drive shaft 103 close to the second cleaning mechanism 3, a positioning step is partially protruded outward. And one end of the worm gear 401 close to the second cleaning mechanism 3 abuts against the positioning step, and the other end abuts against the distance sleeve. And on the shaft body at the other end of the drive shaft 103, a slotted nut is coaxially assembled. And one end of the worm gear 401 far from the second cleaning mechanism 3 abuts against the slotted nut, and the other end abuts against the distance sleeve. On the drive shaft 103 at both ends of a row of the large bevel gears 204, they are respectively assembled on the cleaning housing 201 through two stainless steel tapered bearings. And on both sides of one of the stainless steel tapered bearings, they respectively abut against two distance sleeves. And on both sides of the other stainless steel tapered bearing, they respectively abut against the distance sleeve and the adjacent large bevel gear 204.

[0058] In summary, through the combined use of two stainless steel tapered bearings, multiple distance sleeves, a slotted nut, and the positioning step on the drive shaft 103, so that multiple large bevel gears 204 and two worm gears 401 are respectively fixed on the drive shaft 103 correspondingly.

[0059] In addition, through multiple distance sleeves, so that multiple large bevel gears 204 can be coaxially assembled on the drive shaft 103 at equal intervals.

[0063] In the above solution, a plurality of nozzles 5 are provided through the cleaning housing 201, and the nozzles are connected to an external water pipe. In addition, a through hole for the water pipe to enter its interior is preset on the cleaning housing 201. The external water pipe can be directly connected to the nozzle 5 from the outside of the cleaning housing 201, or the water pipe can enter its interior through the through hole from the inside of the cleaning housing 201 and then be connected to the nozzle 5.

[0064] In the above solution, the brush body on the rotary brush 202 and the brush plate 302 can be made of flexible material or rigid material.

[0065] In summary, the intelligent gun bore cleaning machine provided by the present invention overcomes the problems in the prior art that during use, only the drive shaft is used to drive the brush to rotate accordingly to clean the inner wall of the gun bore, the cleaning method is single, resulting in poor cleaning effect, and the brush is worn during long-term use, and the worn brush becomes shorter, making it difficult to contact the inner wall of the gun bore during later use, resulting in the problem of incomplete cleaning of the inner wall of the gun bore.
