Description

Technical Field

[0001] This utility model belongs to the field of aviation equipment technology, specifically relating to an anti-fouling device for aircraft tire tread coating. Background Technology

[0002] As a critical component for aircraft takeoff, landing, and taxiing, aircraft tires are highly susceptible to contamination from runway debris, oil, and chemicals. This contamination accelerates tire wear, reduces the coefficient of friction, and can even lead to skidding and other safety hazards. Current methods for preventing tire contamination primarily rely on manual cleaning or applying antifouling agents. Manual cleaning requires significant manpower and its effectiveness is unreliable, failing to provide long-term protection. Antifouling agents, on the other hand, suffer from poor durability and require frequent maintenance. Both methods lack automated coating mechanisms, making it difficult to establish a continuously effective antifouling barrier during tire use. This results in high maintenance costs for aircraft tires and persistent safety risks.

[0003] The antifouling coating equipment for aircraft tires provided by this invention integrates automatic clamping, film guiding, heating and softening, and pressure bonding into a single mechanical structure. A screw-nut driven clamping mechanism securely fixes the tire, while a J-shaped distribution of guide rollers and a cylinder-adjusting roller work together to control the tension of the antifouling film. A heating device and an elastic pressure roller complete the softening, bonding, and cutting of the antifouling film. This equipment, through an intelligent controller that coordinates the linkage of all components, forms a fully automated coating process, fundamentally solving the problems of low efficiency, high cost, and short-lived protective effects of traditional antifouling methods, providing a durable and efficient antifouling protection solution for aircraft tires.

Both lack an automated coating mechanism, making it difficult to build a continuous and effective antifouling barrier during tire use, resulting in high maintenance costs and safety risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Multiple guide rollers are installed at the adjacent ends of the two first fixing frames, arranged in a J-shape between the two first fixing frames. A second fixing frame is fixedly connected to one side of each of the two first fixing frames. A tire base is rotatably connected to the lower of one of the first fixing frames. A first motor is installed at the bottom of the first fixing frame, and the output end of the first motor is fixedly connected to the bottom of the tire base.

[0008] Two sets of tread coating mechanisms are provided, which are located between two first fixed frames. The two sets of tread coating mechanisms are used to tightly press the antifouling film onto the tire tread.

[0009] As a preferred embodiment of this utility model, one set of the tread coating mechanism includes:

[0010] The protective cover is fixedly connected to the outer surface of the two first fixing frames;

[0016] An embedded motor, wherein the embedded motor is fixedly connected to the inner wall of one side of one of the limiting grooves;

[0017] A clamping mechanism is provided in a limiting groove and is used to clamp an aircraft tire.

[0018] As a preferred embodiment of this utility model, the clamping mechanism includes:

[0019] A lead screw, one end of which is rotatably connected to the inner wall of a limiting groove, and the other end of which is fixedly connected to the output end of an embedded motor;

[0020] Two nuts, both of which are threaded onto the circumferential surface of the lead screw, with one of the nuts being threaded onto the circumferential surface of the lead screw in the opposite direction;

[0021] An arc-shaped guide plate is fixedly connected to the adjacent ends of two first fixed frames, and the arc-shaped guide plate is located on one side of the heating device;

[0022] Two arc-shaped pads are respectively fixedly connected to the far ends of two nuts;

[0023] Two clamping blocks are fixedly connected to the circumferential surfaces of two nuts, and the two clamping blocks are slidably connected to two limiting grooves.

[0024] In a preferred embodiment of this utility model, a cylinder is installed inside the second fixed frame, and an adjusting roller is slidably connected inside the second fixed frame. The output end of the cylinder is fixedly connected to the circumferential surface of the adjusting roller.

A screw-nut driven clamping mechanism securely fixes the tire. J-shaped distributed film guide rollers and cylinder adjusting rollers work together to control the tension of the antifouling film. A heating device and elastic pressure film rollers complete the softening, bonding, and cutting of the antifouling film. The equipment uses an intelligent controller to coordinate all components, forming a fully automated coating process that completely replaces manual cleaning and coating. Operators only need to perform simple parameter settings and start the machine; the equipment automatically completes the entire process from tire fixing and antifouling film pretreatment to automated coating. This significantly reduces labor costs and improves antifouling efficiency. Compared to traditional manual cleaning methods, it saves a significant amount of manpower and also increases the speed and efficiency of antifouling processing, allowing tires to be put into use more quickly.

[0029] 2. In this solution, the heating device heats the antifouling film during the transmission process, softening it to a suitable degree. The softened antifouling film has better plasticity and adhesion, allowing it to adhere more tightly to the tire tread during subsequent pressing. This enhances the bonding effect between the antifouling film and the tire tread, forming a more effective antifouling barrier. Compared with traditional antifouling agents, the antifouling film has more stable and durable antifouling performance, effectively blocking runway debris, oil, water stains, chemicals, and other contaminants from polluting the tire tread and extending tire life.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figures 1-4The present invention provides the following technical solution:

[0039] An antifouling device for aircraft tire tread coating includes:

[0040] Two first fixing frames 1 are provided, with anti-fouling film rolls 2 installed at their adjacent ends. A second motor 8 and a heating device 102 are fixedly connected to the top of one of the first fixing frames 1. Multiple guide rollers 3 are installed at the adjacent ends of the two first fixing frames 1, arranged in a J-shape between the two first fixing frames 1. A second fixing frame 103 is fixedly connected to one side of each of the two first fixing frames 1. A tire base 4 is rotatably connected inside one of the lower first fixing frames 1. A first motor is installed at the bottom of the first fixing frame 1, and the output end of the first motor is fixedly connected to the bottom of the tire base 4.

[0041] Two sets of tread coating mechanisms are located between two first fixed frames 1. The two sets of tread coating mechanisms are used to tightly press the antifouling film onto the tire tread.

[0042] In a specific embodiment of this utility model, the two first fixing frames 1 serve as the basic support structure of the entire device, providing mounting carriers for other components, ensuring that each component maintains a relatively stable positional relationship during operation, making the overall structure of the device stable, and ensuring the stability of the device operation.

[0043] Antifouling film roll 2 is used to store antifouling film, which is the source of antifouling material for aircraft tire treads. During equipment operation, the antifouling film is gradually unfolded from antifouling film roll 2 and, with the cooperation of other components, covers the tire tread.

[0044] The second motor 8 serves as a power source, providing power for the transport of the antifouling membrane. By driving the connecting components, it drives the antifouling membrane roll 2 to rotate, enabling the antifouling membrane to unfold from the roll in a predetermined direction and speed, and sequentially pass through multiple guide rollers 3 to complete the transport process of the antifouling membrane.

[0045] The heating device 102 heats the antifouling film during the transfer process to soften it to a suitable degree. After being heated and softened, the antifouling film has better plasticity and adhesion, allowing it to adhere more tightly to the tire tread during subsequent pressing, thus enhancing the bonding effect between the antifouling film and the tire tread and forming a more effective antifouling barrier.

[0046] Multiple guide rollers 3 are arranged in a J-shape between the two first fixed frames 1, serving to guide the antifouling film's transmission path. Through reasonable layout and angle settings, the direction and tension of the antifouling film are controlled, ensuring that the antifouling film can be smoothly and orderly transmitted from the antifouling film roll 2 to the tire tread coating area. At the same time, it ensures that the antifouling film will not wrinkle or shift during transmission, providing a good foundation for subsequent coating operations.

[0047] The second mounting bracket 103 further enhances the structural stability of the equipment, provides additional support for some components, and can also be used to install auxiliary components related to equipment operation, such as control lines and sensors, optimize the overall layout of the equipment, and ensure the coordinated operation of various components of the equipment.

[0048] The tire base 4 is used to support the aircraft tire, providing a platform for its placement. It is rotatably connected to the first fixing frame 1 and can rotate under the drive of the first motor. During the coating process, the tire base 4 drives the tire to rotate, ensuring that the antifouling film can evenly cover the entire tire surface, avoiding uneven coating and ensuring the coating effect.

[0049] The first motor serves as the power source for the tire base 4. By outputting power, it drives the tire base 4 to rotate, causing the tire to rotate at a predetermined speed and direction during the coating process. This, in conjunction with the coating mechanism, completes the all-round and uniform coating operation on the tire tread.

[0050] The two sets of tread coating mechanisms are located between the two first fixed frames 1 and are the core actuators for ensuring that the antifouling film is tightly pressed onto the tire tread. After the antifouling film is heated and transported to the tire tread, the tread coating mechanism uses specific structures and actions, such as the squeezing and bonding of the pressure rollers, to tightly press the antifouling film onto the tire tread, ensuring that the antifouling film is in full contact and adheres to the tire tread, forming effective antifouling protection.

[0051] Please refer to the details. Figures 1-4 One set of tread coating mechanisms includes:

[0052] Protective cover 5 is fixedly connected to the outer surface of the two first fixing brackets 1;

[0053] Two limiting rods 501 are slidably connected inside the protective cover 5;

[0054] Two limiting pads 503 are fixedly connected to the circumferential surfaces of two limiting rods 501 respectively;

[0055] Support sleeve, the support sleeve is slidably connected inside the protective cover 5;

[0056] The pressure roller 7 is rotatably connected inside the support sleeve;

[0057] Two springs 502 are fixedly connected to the adjacent ends of the support sleeve and the protective cover 5, respectively.

[0058] Embedded motor 9 is fixedly connected to one side inner wall of one of the limiting grooves 401;

[0059] The clamping mechanism is located in the limiting groove 401 and is used to clamp the aircraft tire.

[0060] In this embodiment: First, the aircraft tire is placed on the tire base 4. The embedded motor 9 drives the clamping mechanism to firmly clamp the tire. The second motor 8 starts, driving the antifouling film roll 2 to rotate, causing the antifouling film to unfold and pass through multiple guide rollers 3 in sequence, reaching the heating device 102 for heating and softening. At this time, the first motor drives the tire base 4 to rotate, causing the tire to rotate. Simultaneously, the pressure roller 7, under the elastic action of the spring 502, is tightly attached to the tire surface. As the tire rotates, the pressure roller 7 also rotates, evenly pressing the heated and softened antifouling film onto the tire surface. During the pressing process, the limiting rod 501 and the limiting pad 503 ensure the stability of the movement trajectory of the pressure roller 7, and the protective cover 5 provides safety protection for the entire coating process. After the antifouling film completely covers the tire surface, the external equipment cutting knife cuts the antifouling film, completing one coating operation. Throughout the process, all components work together to achieve efficient and uniform antifouling coating of the aircraft tire surface.

[0061] Please refer to the details. Figures 1-3 The clamping mechanism includes:

[0062] The lead screw 11 has one end rotatably connected to the inner wall of the limiting groove 401, and the other end is fixedly connected to the output end of the embedded motor 9.

[0063] Two nuts 12 are threaded onto the circumferential surface of the lead screw 11, with one of the nuts 12 being threaded onto the circumferential surface of the lead screw 11 in the opposite direction.

[0064] Arc-shaped guide plate 14 is fixedly connected to the close ends of the two first fixing frames 1, and the arc-shaped guide plate 14 is located on one side of the heating device 102.

[0065] Two arc-shaped pads 6 are fixedly connected to the far ends of two nuts 12 respectively;

[0066] Two clamping blocks 13 are fixedly connected to the circumferential surfaces of two nuts 12, and the two clamping blocks 13 are slidably connected to the two limiting grooves 401.

[0067] In this embodiment: When it is necessary to clamp the aircraft tire, the operator starts the embedded motor 9 through the intelligent controller 15. The embedded motor 9 starts to run, and its output end drives the lead screw 11 to rotate. Since the two nuts 12 are connected to the lead screw 11 with forward and reverse threads respectively, according to the principle of thread transmission, the rotation of the lead screw 11 will cause the two nuts 12 to move in opposite directions along the lead screw 11. During the movement, the nuts 12 drive the clamping block 13 connected to it to slide in the limiting groove 401 to ensure the accuracy of the movement direction; at the same time, the nuts 12 also drive the arc-shaped pads 6 to move towards the tire. With the continuous movement of the nuts 12, the two arc-shaped pads 6 gradually approach and fit against the outer surface of the aircraft tire, increasing the contact area with the tire and applying a uniform clamping force to firmly fix the tire on the tire base 4.

[0068] After the coating operation is completed, the embedded motor 9 rotates in the opposite direction, and the lead screw 11 rotates in the opposite direction as well. The two nuts 12 move relative to each other under the action of the lead screw 11, which drives the arc-shaped pad 6 and the clamping block 13 to move away from the tire, thereby loosening the clamping on the tire and making it easier for the operator to remove the tire.

[0069] Please refer to the details. Figure 2 A cylinder 104 is installed inside the second fixed frame 103, and an adjusting roller 105 is slidably connected inside the second fixed frame 103. The output end of the cylinder 104 is fixedly connected to the circumferential surface of the adjusting roller 105.

[0070] In this embodiment: when it is necessary to adjust the transmission tension or position of the antifouling film, the intelligent controller 15 sends a command to the cylinder 104, and the output end of the cylinder 104 pushes or pulls the adjusting roller 105 to slide within the second fixed frame 103. The adjusting roller 105 adjusts the tension of the antifouling film by changing the transmission path and contact angle of the antifouling film, ensuring that the antifouling film remains flat during transmission, providing good conditions for the subsequent pressing roller 7 to tightly press the antifouling film onto the tire surface, and ensuring the uniformity and quality of the coating.

[0071] Please refer to the details. Figures 1-4 A plastic sleeve 101 is fixedly connected to the outer surface of one of the first fixing frames 1 on the upper side, and a plastic ring 10 is fixedly connected to the top edge of the tire base 4.

[0072] In this embodiment, the plastic sleeve 101 and the plastic ring 10 are made of plastic material with certain elasticity and wear resistance. During the tire rotation process, if the tire has a slight collision or contact with the edge of the first fixing frame 1 or the tire base 4 due to an accident, the plastic sleeve 101 and the plastic ring 10 can play a buffering and protective role.

[0073] Please refer to the details. Figures 1-3A label 106 is fixedly connected to the top of the other lower first fixing frame 1, and a smart controller 15 is fixedly connected to one side of both first fixing frames 1.

[0074] In this embodiment: the label 106 is fixedly connected to the top of the lower first fixing frame 1 and can be used to identify relevant equipment information, such as equipment model, specifications, operating instructions, maintenance cycle, etc. The intelligent controller 15 is fixedly connected to one side of the two first fixing frames 1 and serves as the control core of the equipment. It receives instructions input by the operator through the operation panel, as well as equipment operation data fed back by distance sensors, temperature sensors, etc. According to the preset program and real-time data, the intelligent controller 15 sends control signals to components such as the embedded motor 9, the first motor, the second motor 8, the cylinder 104, and the heating device 102, coordinating the working rhythm and operating status of each component, so that the entire aircraft tire tread coating and antifouling equipment can operate efficiently and stably, completing the coating and antifouling operation of aircraft tires.

[0075] The working principle and usage process of this utility model are as follows: An aircraft tire is placed on a tire base 4. The embedded motor 9 is started by the intelligent controller 15, which drives the lead screw 11 to rotate. Due to the opposing thread design of the two nuts 12 on the lead screw 11, the nuts 12 move in opposite directions, causing the clamping block 13 to slide and guide within the limiting groove 401. The clamping block 13 then adheres to the outer surface of the tire to complete the clamping and fixing. Next, the second motor 8 drives the antifouling film roll 2 to unfold. The antifouling film is guided by the J-shaped guide rollers 3 into the heating device 102 for softening. Simultaneously, the intelligent controller 15 controls the cylinder 104 to push the adjusting roller 105 to slide and adjust the film's transmission tension. Subsequently, the first motor drives the tire... The base 4 rotates, and the pressure roller 7, under the elastic action of the spring 502, tightly adheres to the tire surface. As the tire rotates, the pressure roller 7 also rotates, evenly pressing the heated and softened antifouling film onto the tire surface. During the film pressing process, the limiting rod 501 and the limiting pad 503 ensure the stability of the movement trajectory of the pressure roller 7. When the antifouling film completely covers the tire surface, the external equipment film cutter cuts the antifouling film, completing one film covering operation. After completion, the external equipment film cutter is triggered to cut the antifouling film, thereby realizing intelligent collaboration of the entire process from tire fixing, film transfer pretreatment to automated film covering, solving the problems of traditional antifouling methods relying on manual labor and short-term protection.

[0076] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
