[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] After the gun barrel is used, residues will adhere to its inner wall. These residues will reduce the surface finish of the inner wall and increase the frictional resistance. Therefore, corresponding equipment is needed to clean its inner wall, and the inner wall of the gun barrel can be effectively decontaminated by laser cleaning.

[0004] Existing pipeline robots lack a compatibility design with the oiling function, resulting in the need to rely on manual use of an oiling rod or auxiliary tools to perform oiling and anti-corrosion operations on the inside of the gun barrel after cleaning, making the entire gun barrel maintenance process fragmented and limited in efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the above deficiencies and provide a pipeline robot for cleaning gun barrels to achieve the purpose of integrating laser cleaning and oiling functions and reducing the process switching time.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-7 , the present invention discloses a pipeline robot for gun barrel cleaning, including:

[0031] A laser cleaning head 1 for irradiating the inner wall of the gun barrel with laser to clean the inner wall of the gun barrel;

[0032] A traveling mechanism 2 for driving the laser cleaning head 1 to travel inside the gun barrel;

[0033] An air curtain assembly 3 is arranged on the laser cleaning head 1 for generating high-pressure air to form an air curtain around the laser lens of the laser cleaning head 1;

[0034] An oiling mechanism 4, the oiling mechanism 4 includes a docking assembly 41 for detachably connecting with the air curtain assembly 3, a liquid spraying assembly 42 for spraying liquid onto the inner wall of the gun barrel is rotatably arranged on one side of the docking assembly 41 away from the air curtain assembly 3, and a smearing assembly 43 capable of synchronously rotating with the liquid spraying assembly 42 and wiping the gun barrel is arranged on the liquid spraying assembly 42.

[0035] In the present invention, by improving the existing laser cleaning robot, the oiling mechanism 4 can be selectively connected to the air curtain assembly 3. When the oiling mechanism 4 is not installed, the traveling mechanism 2 can drive the laser cleaning head 1 to travel inside the gun barrel to remove the residues inside the gun barrel, and the air curtain assembly 3 is used to block the residues during cleaning from contaminating the laser cleaning head 1; after the oiling mechanism 4 is installed, the traveling mechanism 2 can also drive the oiling mechanism 4 to travel inside the gun barrel. Through the coordinated action of the liquid spraying assembly 42 and the smearing assembly 43, the protective liquid is evenly sprayed onto the inner wall of the gun barrel and smeared, ensuring the uniformity and comprehensiveness of oiling. The pipeline robot integrates the functions of laser cleaning, high-pressure air curtain protection, and automatic oiling, can quickly complete the rapid switching between the cleaning and anti-corrosion maintenance of the inner wall of the gun barrel, and effectively improves the efficiency and quality of gun barrel maintenance.

[0036] In one embodiment, the liquid spraying assembly 42 includes an end plate 421. At one end of the end plate 421, there is an air guide ring 422 that can be docked with the air outlet end of the air curtain assembly 3. A plurality of air guide channels 423 are arranged in the air guide ring 422. On the end plate 421, there are a plurality of Venturi injectors 424 for spraying liquid onto the inner wall of the gun barrel. The intake end of each Venturi injector 424 is communicated with the air guide channel 423. The liquid spraying assembly 42 further includes a liquid storage component for supplying liquid to each Venturi injector 424.

[0037] With such a design, by utilizing the Venturi effect of the Venturi injector 424, after the oiling mechanism 4 is docked with the air curtain assembly 3, the high-speed air flow generated by the air curtain assembly 3 can enter each Venturi injector 424 through the air guide channel 423, generating a negative pressure in the reduced-diameter section of the Venturi injector 424. The negative pressure is used to extract the liquid in the liquid storage component, mix it with the high-pressure gas, and then spray it onto the inner wall of the gun barrel. This enables the liquid spraying assembly 42 to complete the liquid spraying operation without additional liquid spraying power, making the equipment more convenient for maintenance and component replacement.

[0038] Preferably, the plurality of Venturi injectors 424 are evenly distributed in a ring on the outer peripheral wall of the end plate 421, improving the uniformity and coverage area of liquid spraying.

[0039] In one embodiment, the liquid storage component includes an oil storage tank 425 fixedly arranged in the air guide ring 422. The oil storage tank 425 is cylindrical. At one end of the oil storage tank 425, there is a swivel joint 426. A liquid guide pipe 427 is arranged between the swivel joint 426 and the liquid inlet end of each Venturi injector 424. An L-shaped liquid inlet pipe 428 inserted into the oil storage tank 425 is rotatably arranged on the swivel joint 426. The axis of the rotation shaft of the L-shaped liquid inlet pipe 428, the axis of the air guide ring 422, and the axis of the oil storage tank 425 are all on the same straight line, so that the liquid inlet of the L-shaped liquid inlet pipe 428 remains downward when the L-shaped liquid inlet pipe 428 rotates in the oil storage tank 425.

[0040] With such a design, since the L-shaped liquid inlet pipe 428 is rotatably connected to the swivel joint 426, the L-shaped liquid inlet pipe 428 can keep the liquid inlet downward under its own gravity, so that it is not affected by the position after the installation of the oiling mechanism 4 and the air curtain assembly 3, ensuring that the L-shaped liquid inlet pipe 428 can extract the liquid in the oil storage tank 425 at each position.

[0041] It should be noted that the swivel joint 426 and the L-shaped liquid inlet pipe 428 are in dynamic seal connection. After the liquid enters the swivel joint 426 through the L-shaped liquid inlet pipe 428, it is divided into multiple streams of liquid and enters each Venturi injector 424. And a one-way liquid replenishing valve is arranged at the center of the oil storage tank 425. The liquid height in the oil storage tank 425 is not higher than the height of the one-way liquid replenishing valve, so that external liquid and gas can enter the oil storage tank 425 through the one-way liquid replenishing valve, while the internal liquid cannot be discharged through the one-way liquid replenishing valve during use.

[0042] In one embodiment, the coating assembly 43 includes a plurality of coating heads 431 disposed on the side of the end plate 421 away from the air guide ring 422 and distributed in a ring shape. A connecting rod 432 inserted into the end plate 421 is provided on the coating head 431. A sliding groove for the connecting rod 432 to slide is provided in the end plate 421. The coating assembly 43 further includes a synchronous driving member for driving the plurality of connecting rods 432 to move toward and away from the axis of the end plate 421.

[0043] With such a design, before the oiling mechanism 4 enters the gun barrel, the operator can synchronously adjust the positions of the plurality of connecting rods 432 according to the inner diameter of the gun barrel, so that the coating heads 431 can closely adhere to the inner wall of the gun barrel after entering the gun barrel, thereby enabling the coating heads 431 to adapt to gun barrels of different calibers and improving the versatility and flexibility of the equipment.

[0044] Preferably, the coating head 431 is a sponge head or a rubber head, so that the coating head 431 will not damage the gun barrel during the coating process.

[0045] In one embodiment, the synchronous driving member includes a turntable 433 rotatably disposed at one end of the end plate 421 away from the air guide ring 422 and a dial rod 434 disposed on each connecting rod 432. One end of the dial rod 434 away from the connecting rod 432 is inserted into the turntable 433. An arc-shaped groove for guiding the movement of the dial rod 434 is provided in the turntable 433. When the turntable 433 rotates, the dial rod 434 is pushed by the turntable 433 to move toward and away from the axis of the end plate 421 along the arc-shaped groove;

[0046] The synchronous driving member further includes a spring pin 435 disposed at one end of the end plate 421 away from the air guide ring 422. When the spring pin 435 is in a natural state, it is inserted into the turntable 433. A plurality of slots for the spring pin 435 to be inserted are provided on the turntable 433.

[0047] With such a design, when the operator adjusts, he only needs to release the locking of the turntable 433 by the spring pin 435 first, then rotate the turntable 433 to push the dial rod 434 to move, and with the cooperation of the arc-shaped groove, adjust the connecting rod 432 and the coating head 431 to the required positions. After the adjustment is completed, lock the turntable 433 by the spring pin 435 to fix the position of the coating head 431.

[0048] In a specific implementation, a handle is provided on the turntable 433, so that the operator can control the adjustment of the turntable 433 by rotating the handle.

[0049] In one embodiment, a guide rod 5 for being inserted into the rifling of the gun barrel is fixedly provided on the end plate 421. The guide rod 5 is composed of a fixed sleeve provided on the end plate 421 and a movable sleeve threadedly connected to the fixed sleeve.

[0050] With such a design, by inserting the guide rod 5 into the rifling of the gun barrel, when the traveling mechanism 2 moves, the guide rod 5 travels along the rifling, thereby driving the end plate 421 connected to the guide rod 5 to rotate, so that the coating head 431 also installed on the end plate 421 rotates together, achieving the effect of rotating and coating while traveling, and thus effectively improving the coating uniformity and comprehensiveness.

[0051] In one embodiment, the docking assembly 41 includes an outer screw sleeve 411 that is rotatably connected to the end plate 421 and sleeved outside the air guide ring 422. An internal thread ring 412 is threadedly connected to the outer screw sleeve 411, and an external thread groove for the internal thread ring 412 to be threadedly connected is provided on the air curtain assembly 3.

[0052] With such a design, the operator can quickly complete the connection operation or disassembly operation of the oil coating mechanism 4 and the air curtain assembly 3, further improving the convenience of the equipment when replacing components.

[0053] It should be noted that after the oil coating mechanism 4 and the air curtain assembly 3 are docked, the outer screw sleeve 411 can prevent oil mist from contaminating the laser cleaning head 1.

[0054] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0055] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0056] In addition, "a plurality" means two or more.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
