Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and in particular, to a gun barrel scrubbing device driven by a cylinder. Background Art

[0002] The cleanliness and wear degree of the gun barrel affect the accuracy, reliability of shell firing and the service life of the gun. Due to unclean gun barrel cleaning, copper hanging and carbon deposition occur, resulting in the movement of the projectile being blocked in the gun barrel and causing a chamber explosion. Therefore, the gun barrel of a large-caliber gun needs to be cleaned and maintained when it is unsealed or sealed, and after firing a shell. The cleaning of the gun barrel includes the removal of foreign objects in the gun barrel and the anti-rust treatment of the gun barrel. Foreign objects in the gun barrel include metals such as copper, zinc, lead, and aluminum shed from the projectile, oxidation residues of aluminum, and combustion residues of gunpowder in the chamber, such as soot and graphite attached to the inner wall of the gun barrel, as well as foreign objects generated by gun barrel rust. The above foreign objects are likely to block and corrode the inner wall of the gun barrel, intensifying the wear and corrosion of the inner wall of the gun barrel. Especially during the firing of the gun, the residues (carbon deposition) attached to the inner wall of the gun barrel generated under high temperature and high pressure are tightly combined with the gun barrel; in addition, since the length of the gun barrel is much larger than the inner diameter of the gun barrel wall, gun barrel cleaning and maintenance is an extremely difficult task, especially the cleaning of the shaded part of the rifling on the inner wall of the gun barrel is more difficult. Especially during field operations at sea, the scrubbing of the gun barrel requires high efficiency and easy operation.

[0003] Existing gun barrel cleaning mostly adopts a combination of wiping agents and mechanical scrubbing. Initially, it was to manually scrub the gun barrel by dipping a wiping agent on the brush head. On the one hand, the wiping agent is formulated from highly toxic and strongly corrosive substances such as potassium dichromate and sodium hydroxide, with strong toxicity and corrosiveness. Gun barrel cleaning workers are prone to contact the wiping agent when repeatedly dipping it, causing harm to the body. On the other hand, manual scrubbing requires a lot of manpower and time, with low work efficiency and high labor intensity. On the other hand, for a longer gun barrel, the cleaning of the middle and deep parts of the gun barrel is more difficult, it is easy to be unclean, and manual cleaning is likely to cause slight damage to the gun barrel. Generally speaking, manual gun barrel cleaning has high labor intensity, low work efficiency, and is likely to cause personal injury to the scrubbing workers and damage the gun barrel.

[0004] Although there are also some electric washing machines at the present stage, they use circuit control. The circuit is easily corroded by the cleaning agent, affecting the cleaning efficiency and the normal operation of the cleaning equipment. Once the braking module fails, the cleaning equipment is likely to get stuck in the barrel and be difficult to remove, bringing the risk of damaging the gun barrel. Summary of the Invention

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] Embodiment 1 Refer to Figure 1 and Figure 2 , this embodiment provides a gun barrel cleaning device driven by a cylinder, including: A driving module, the driving module includes a power part, the power part includes two cylinders, a first cylinder and a second cylinder. A piston that fits against the inner wall of the cylinder is provided inside the cylinder. The piston slides horizontally and is limited inside the cylinder. A cylinder rod penetrates through the middle of the power part, and the cylinder rod is fixedly connected to the piston; A cleaning module, the cleaning module includes a first brush and a second brush. When the first brush and the second brush enter the gun barrel, they are in close contact with the inner wall of the gun barrel to generate frictional force. The first brush is connected to the front end of the cylinder rod, and the first brush is configured to be able to rotate around the axis of the cylinder rod. The second brush is fixedly connected to the rear end of the cylinder rod; When the piston moves, it drives the cylinder rod to move synchronously, and the cleaning module synchronously moves horizontally.

[0028] The gun barrel cleaning device driven by a cylinder provided in this embodiment, its movement process specifically includes two parts: cleaning and crawling, as follows: When the gun barrel cleaning device is placed in the gun barrel, the braking part expands, and the gun barrel cleaning device is in a state of being stationary relative to the gun barrel. The cleaning module makes a reciprocating motion back and forth under the drive of the power part to realize the synchronous cleaning process of the first brush and the second brush; When a cleaning process is completed, when the first brush or the second brush extends to the longest position, the piston is located at the left end face or the right end face inside the cylinder, the braking part is contracted, and the power part drives the cleaning module to move forward or backward. Due to the resistance of the cleaning module relative to the inner wall of the gun barrel, the gun barrel cleaning device moves forward or backward relative to the inner wall of the gun barrel to realize the crawling process of the gun barrel cleaning device.

[0029] It further includes a connection module, the connection module includes a connector and a connection pipe. The connector includes a first connection seat and a second connection seat. The first connection seat is fixed to the rear end of the cylinder rod and the first connection seat is located behind the second brush. The second connection seat is arranged at the front end of the connection pipe. The rear end of the connection pipe is connected to the control module. The first connection seat and the second connection seat are locked to each other through threaded holes, and there is an anti-misalignment setting at the threaded connection, which can speed up the connection speed and connection accuracy. An air supply pipeline and a liquid supply pipeline are provided inside the connection pipe. The air supply pipeline and the liquid supply pipeline are not shown in the figure and are flexible hoses. Although the bending of the corrugated pipe can change its shape, it can maintain normal movement. The connector is provided with notches corresponding to the air supply pipeline and the liquid supply pipeline one by one.

[0030] Refer to Figure 9, further comprising at least one connecting member. In this embodiment, the number of connecting members is set to three. The three connecting members are distributed on the same circumference and present a 120° angle with each other. The connecting member penetrates through the middle of the second brush. A plurality of first channels corresponding to the air supply pipeline and the liquid supply pipeline one by one are arranged inside the connecting member. In this embodiment, three first channels are arranged in each connecting member. The first channels are used for supplying air and liquid to the driving module. And in order to maintain the stable operation of the equipment and cope with emergencies, the number of first channels is greater than the number of channels required for actual work, and the redundant channels are used for emergencies; the first channels penetrate through the horizontal direction of the connecting member. The left side of the connecting member is communicated with the braking part, and the right side of the connecting member is communicated with the notch.

[0031] See Figure 3 , Figure 5 and Figure 10 , the braking part includes a brake main body. The brake main body is sleeved on the outer circumference of the cylinder rod. A plurality of notches are formed on the outer peripheral surface of the brake main body. A plurality of expansion air bags are arranged inside the brake main body. An expansion block is attached to the upper surface of the air bag. Both ends of the air bag are fixed inside the brake main body through buckles. When the air bag is inflated and expands, it squeezes the expansion block and extends outward from the notch until it is tightened against the inner wall of the gun barrel.

[0032] When the gun barrel cleaning device starts to clean, the braking part must support the pipe wall to keep the main body stationary. The brake uses the expansion and contraction of the air bag to drive the expansion block to float and tightly fit the inner wall of the gun barrel. The outer shell of the braking part and the cylinder block are processed from the same workpiece and have the functions of guiding air and water.

[0033] When needed, a silicone rubber sleeve can also be sleeved outside the braking part to increase friction and dust prevention. The brake main body is connected to the cylinder, but not to the cylinder rod. The inner core of the brake main body is isolated from the cylinder rod by a steel pipe with an oil scraping and dust-proof oil seal. The two ends are the end sealing and fixing mechanisms of the air bag, so that there is enough fixing force when the air bag is inflated and pressurized. The air bag is fixed by being sleeved on an interference cylinder, with a larger end and a slightly smaller front end. When the air bag is sleeved, a pressure device is used to tighten the buckle made of stainless steel. The buckle has a threaded hole, and the screw can only be inserted when compressed to a certain position, so that the air bag is tightly locked. As long as the screw does not withdraw, there is no possibility of loosening. This locking method effectively solves the difficulty of small space and large locking force.

[0034] Further see Figures 6 to 8, a reduced-diameter seat is provided at the rear end of the brake main body. A reduced-diameter connecting disk is provided in the middle of the reduced-diameter seat. The reduced-diameter connecting disk includes a first disk body and a second disk body. The second disk body is provided in the middle of the first disk body, and the left and right end faces of the second disk body extend to the outside of the left and right end faces of the first connecting disk. A first connecting surface is formed by inward depression of the right end face of the second disk body. A third connecting disk is provided in the middle of the surface of the first connecting surface. A number of first interfaces are provided on the outer peripheral side of the third connecting disk. The positions and numbers of the first interfaces correspond to the first channels one by one. The first disk body, the second disk body, and the third disk body are concentrically arranged.

[0035] A number of second interfaces are provided on the circumferential side of the left end face of the first disk body. The number of the second interfaces corresponds to the number of the first interfaces one by one, and the connection line of the positions of the second interfaces and the positions of the first interfaces is on the same radial line. A number of connection grooves are vertically provided in the thickness direction of the first disk body. The number of the connection grooves is the same as the number of the first interfaces. The bottom of the connection groove communicates with the first interface. A first nut is sleeved on the top of the connection groove. The bottom of the first nut is flush with the top of the second interface. The first interface is correspondingly communicated with the first channel. The second interface is communicated with the brake main body. A number of second channels are correspondingly provided inside the pipe wall of the brake main body. The right end of the second channel is communicated with the second interface.

[0036] The main function of the reduced-diameter connecting disk is to seal and transfer the gas and liquid provided by the control module from the circumference with a smaller distribution diameter to the circumference with a larger distribution diameter, that is, from the first channel to the second channel.

[0037] It should be noted that: since the airbag and the air cylinder together require 5 paths of air, all of which need to be introduced through the holes opened on the outer wall of the air cylinder housing, and their distribution diameter can only be on the air cylinder wall. If directly connected to the air pipe, it will interfere with the brush. Therefore, a reduced-diameter connecting disk is designed and tightly connected to the connecting part on the reduced-diameter connecting disk. The connecting part is an aluminum extrusion workpiece designed according to space requirements, with 3 channels for air or water inside, arranged in an equidistant distribution of 120 degrees. At the same time, it also serves as the hard connection seat for the subsequent cables and requires a certain rigidity. Therefore, the connecting part is provided with an arc groove near the end and is limited by an inner ring and an outer ring at the same time and is hard connected to the reduced-diameter connecting disk through screws. That is, the position of the first interface is the connection part between the connecting part and the reduced-diameter connecting disk, and the position of the second interface is the connection part between the reduced-diameter connecting disk and the brake main body.

[0038] See Figure 3 and Figure 4, in this embodiment, the power unit includes two cylinders, namely a first cylinder and a second cylinder. The structures of the first cylinder and the second cylinder are the same. A plurality of through connection channels are provided in the tube walls of the first cylinder and the second cylinder. A fixed cylinder screw is provided in the connection channel for serially connecting and locking the first cylinder and the second cylinder in sequence. A sealing seat is provided between the first cylinder and the second cylinder. Protrusions are provided at the left and right ends of the sealing seat, and the protrusions are fitted with the inner walls of the first cylinder and the second cylinder. A connection port corresponding to the connection channel is provided on the periphery of the sealing seat, and the connection port is for the fixed cylinder screw to pass through the sealing seat. The front end of the first cylinder, that is, the left end face of the first cylinder, is connected with a front support seat, and the front support seat is fitted with the inner wall of the first cylinder. The front support seat and the sealing seat jointly seal the first cylinder to form an independent cavity. The rear end of the second cylinder, that is, the right end face of the second cylinder, is connected with a rear support seat. The rear support seat is connected with the braking part through a brake support seat, and the rear support seat is fitted with the inside of the second cylinder. The rear support seat and the sealing seat jointly seal the second cylinder to form an independent cavity. A plurality of liquid outlets are provided on the left end face of the front support seat, and the liquid outlets are for spraying washing liquid onto the first brush.

[0039] Due to the limitation of the outer diameter, the series cylinder specifications are made by special die-casting aluminum extrusion according to technical requirements, and there is no space on the outer wall of the cylinder to install the air circuit connector. Therefore, the shape and structure of the cylinder should combine the functions of multi-channel air guiding, cleaning agent guiding channel, and connection and fixation.

[0040] At least five third channels are provided in the tube walls of the first cylinder and the second cylinder. The positions of the third channels correspond to the positions of any one of the second channels one by one, and the number of the second channels is greater than or equal to the number of the third channels. And any one of the third channels is configured to extend to the left end or the right end of the second cylinder; or extend to the left end or the right end of the first cylinder; or extend to the liquid outlet of the front support seat.

[0041] The third channel is used for: supplying air to or exhausting air from the first cylinder; or supplying air to or exhausting air from the second cylinder; or supplying liquid to the liquid outlet; the second channel is used for providing a gas operation cavity for the third channel or supplying liquid or providing a gas operation channel for the airbag; the first channel is used for providing a gas operation cavity for the second channel or supplying liquid.

[0042] Limiters are provided on the left and right end faces of the piston. When the limiter moves to the left end face or the right end face of the cylinder, the piston moves in the reverse direction.

[0043] See Figure 11, It should be noted that in order for a single cylinder to enable the piston to move left or right, two third channels are required. The end face of one of the third channels only extends to the right side of the cylinder, and the end face of the other third channel extends to the left side of the cylinder, which can meet the requirements of inflating or exhausting air on the left or right side of the piston. It can be understood that the structure of the piston fits the inner wall of the cylinder. When it moves horizontally in the middle of the cylinder, it can divide the cylinder into two independent chambers. The two independent third channels cooperating with it control the inflow and outflow of gas to achieve the left and right movement of the piston. Therefore, the power unit in this embodiment requires at least four third channels, and an additional third channel is also required for discharging the washing liquid. Therefore, it can be undoubtedly concluded that at least five third channels are provided in the tube walls of the aforementioned first cylinder and the second cylinder.

[0044] In this embodiment, nine third channels are provided in the tube walls of the first cylinder and the second cylinder. The extra third channels are for dealing with emergencies. For example, when other normally working third channels are suddenly blocked or in other situations where they cannot work, the extra third channels can be used to continue working. Since the airbag of the braking unit also requires a second channel to supply air to it, the number of second channels is greater than the number of third channels. However, when the number of extra second channels is less than the number of extra third channels, it can also be the same.

[0045] Here, it should also be noted that when the airbag is inflated and the expansion block expands and tightens against the gun barrel wall, the frictional force generated between the braking unit, i.e., the expansion block and the gun barrel wall, is much greater than the frictional force between the washing module, i.e., the first brush and the second brush, and the gun barrel wall. Therefore, when inflating the cylinder, the piston drives the cylinder rod and the first brush and the second brush to move simultaneously, and at this time, the whole driving module does not move; when reciprocating washing is required, it only needs to inflate the other side of the cylinder and discharge the original gas to achieve this. This principle is the basic working process of cylinder drive and will not be elaborated here too much. When the braking unit is released, due to the relationship of the frictional force, the movement of the driving module body can be achieved, that is, the crawling process. The switching of the working states of each part of the driving module, i.e., the power unit and the braking unit, and the switching of the channel states are all controlled by the control module. In this embodiment, corresponding valve switching is set in the control module.

[0046] See Figure 12 , the control module includes a control trolley. Inside the control trolley, there are a controller, an air compressor, and a liquid storage tank. The controller is used to control the actions of the driving module and the washing module. The air compressor is used to provide gas for the air supply pipeline. The liquid storage tank is used to provide cleaning liquid for the liquid supply pipeline. A storage slot is provided on the surface of the control trolley, and the storage slot is used to accommodate the driving module and the washing module. The connecting pipe is connected to one side of the control trolley, and the various pipelines inside it are connected to the corresponding devices according to their functions.

[0047] It should be noted here that the control system for the trolley-mounted gun barrel cleaning device integrates operation buttons, a man-machine interface unit, a cleaning agent storage unit, a gun barrel cleaning device storage unit, an air compressor unit, a pipeline cable retraction unit, and a storage unit for components such as brush heads. The main body is made of aluminum alloy industrial aluminum profiles, and universal casters are installed at the bottom for convenient movement. If it is used on a ship, a magnetic attraction mechanism with a switch can be installed at the bottom for locking with the deck. The side guard plates and bearing plates of the trolley are both made of PE plates, which are corrosion-resistant and can be used for a long time.

[0048] For the gun barrel cleaning device provided in this embodiment, at the joints not mentioned above, sealing rings of corresponding specifications are used to achieve the overall sealing of the gun barrel cleaning device.

[0049] Embodiment 2 This embodiment provides a control method for the gun barrel cleaning device driven by a cylinder in Embodiment 1, which is as follows: Arrangement of buttons: The physical buttons are equipped with a power switch knob, an emergency stop button, a stop button, a full-automatic brushing button, a key-point brushing button, manual forward, manual backward, brake start, brake release, manual water spraying, and manual water shut-off; except for the power switch button, all other buttons have soft buttons on the touch screen, and their functions are the same; Parameter setting: It is divided into a global function part and a local function part A. Global function parameter part: 1. Spraying frequency and duration; 2. Time values for starting and releasing the brake (i.e., the braking part); B. Local function parameter part: 1. Length of full-automatic brushing; (the length is an integer multiple of 80, the same below) 2. Number of reciprocations of the brush head during full-automatic brushing; 3. Length of key-point brushing (if not set, it is considered to brush in place); 4. Number of reciprocations of the brush head during key-point brushing; 5. Manual forward length (from the current position); 6. Manual backward length (from the current position); 3. Whether in full-automatic or manual operation, the water spraying start and stop buttons are non-self-resetting buttons. Once pressed, they will always be in the closed or started state; the brake start and release buttons are self-resetting buttons. Once pressed, they will have an impact within a single scan cycle of the PLC, but in the next scan cycle, when there are commands for the above functions, they will resume their functions and execute according to the new commands.

[0050] 4. The entire control process is as follows: Preparation work: A. Turn on the power switch. At this time, the PLC is turned on, starts up and completes the preparation work, waiting for the operation.
