Description

Technical Field

[0001] The present invention relates to the technical field of airport runway degluing, and more specifically, to a multi-field fusion laser degluing method and device for airport runways. Background Art

[0002] An airport runway is a long strip area in an airport for aircraft takeoff, landing, and taxiing. Its surface is flat and solid, providing a key guarantee for the safe takeoff and landing of aircraft. During the landing and takeoff of an aircraft, the friction between the tires and the runway surface causes rubber particles to gradually adhere to the runway. Over time, the accumulation of the rubber layer reduces the runway roughness and friction, affecting the takeoff and landing safety. It also hinders drainage, damages the runway structure, interferes with navigation equipment, and damages the airport image. Regular degluing is of great significance for ensuring flight safety and the normal operation of the airport.

[0003] Common degluing methods for airport runways include manual cleaning, dry ice cleaning, shot blasting cleaning, chemical cleaning, etc. There are many deficiencies in the common degluing methods for runways. Manual cleaning is inefficient and not suitable for large airports. High-pressure water cleaning is environmentally friendly, but if the water is not drained in time after cleaning, it is easy to form ice layers in cold regions, reducing the friction coefficient of the runway and the brightness of the lights. Dry ice cleaning is an environmentally friendly and efficient cleaning method, but it will generate noise exceeding 100 decibels during cleaning. Therefore, protective equipment needs to be equipped to reduce noise and dry ice rebound. Shot blasting cleaning was once the preferred cleaning method for civil aviation airports, but the residual pellets (FOD) after its operation were once inhaled by engines many times, causing serious accidents and are currently prohibited in the civil aviation industry. Chemical cleaning has a simple operation, but its disadvantages are high cost and environmental pollution. Summary of the Invention

[0004] The problem solved by the present invention is how to improve the cleaning efficiency during the airport runway cleaning process and reduce the pollution to the environment.

[0005] To solve the above problems, the present invention provides a multi-field fusion laser degluing method for airport runways, including:

[0006] S1: Determine whether the airport runway is a cement runway or an asphalt runway. If it is a cement runway, proceed to step S2; if it is an asphalt runway, proceed to step S3;

[0007] S2: Aspirate dust on the cement runway, and at the same time, select the traveling speed of laser degluing according to the laser energy density;

[0008] S3: Spray water on the asphalt runway to form a liquid film, and at the same time, select the traveling speed of laser degluing according to the laser energy density.

[0009] Optionally, in step S2, in the cement runway, the relationship equation between the traveling speed of laser degluing and the laser energy density is

[0010] Y = 0.0038X - 0.005

[0011] Wherein, Y is the traveling speed of laser debonding; X is the laser energy density.

[0012] Optionally, in step S3, in the asphalt runway, the relationship equation between the traveling speed of laser debonding and the laser energy density is

[0013] Y = 0.0038(X - 7.2) - 0.005

[0014] Wherein, Y is the traveling speed of laser debonding; X is the laser energy density.

[0015] Optionally, in step S3, the thickness of the liquid film is 2 mm to 3 mm.

[0016] Optionally, in step S3, the thickness of the liquid film is 2.5 mm.

[0017] In a second aspect, the present invention provides a laser debonding device for the above-mentioned multi-field fusion laser debonding method for airport runways, comprising: a remote control electric platform, and a pulsed laser, a continuous laser, a continuous-pulsed composite laser head, a dust removal system, a water chiller and a control module installed on the remote control electric platform;

[0018] The continuous-pulsed composite laser head is arranged at the rear of the remote control electric platform; the output ends of the pulsed laser and the continuous laser are connected to the multi-light source input port on the continuous-pulsed composite laser head, and a light output port is arranged on the continuous-pulsed composite laser head for outputting laser with a laser energy density set by the user;

[0019] The dust removal system is used for sucking air on the airport runway to remove dust;

[0020] The water chiller is arranged at the front of the remote control electric platform and is used for spraying water on the airport runway to form a liquid film;

[0021] The control module controls the output power of the pulsed laser and the continuous laser according to the laser energy density set by the user, and sets the forward speed of the remote control electric platform according to the laser energy density.

[0022] Optionally, the output end of the dust removal system is connected to the dust suction port on the continuous-pulsed composite laser head.

[0023] Optionally, the continuous-pulsed composite laser head is installed on a laser head adjusting mechanism, and the laser head adjusting mechanism is used for swinging between a vertical rest position and a horizontal working position; when the laser head adjusting mechanism is in the horizontal working position, the light output port faces the airport runway.

[0024] Optionally, the laser head adjustment mechanism includes a swing arm base and a swing arm. The swing arm is rotatably connected to the swing arm base. The continuous-pulse composite laser head is installed on the swing arm, and the swing arm base is installed on the remote control electric platform.

[0025] Optionally, a plug box is further provided on the remote control electric platform for externally connecting a mobile energy storage power vehicle.

[0026] The beneficial effects of the multi-field fusion laser glue removal method and device for airport runways of the present invention are as follows: The method of using laser for glue removal is more environmentally friendly than traditional chemical methods, reducing the use of chemical agents and environmental pollution, and not generating pollutants such as dust. Moreover, the traveling speed can be selected according to the laser energy density, which can optimize the glue removal process, improve efficiency, and accurately control the glue removal effect. For the different characteristics of cement runways and asphalt runways, pre-treatment methods of dust suction and water spraying to form a film are respectively designed. The dust suction and laser glue removal processes do not use chemical agents compared with traditional glue removal methods, reducing environmental pollution. Through pre-treatment and precise glue removal, the flatness and roughness of the runway surface can be better maintained, reducing runway damage caused by improper glue removal, thereby reducing subsequent maintenance costs and frequencies.

[0040] As Figure 1As shown in the figure, a multi-field integrated laser degluing method for airport runways provided by an embodiment of the present invention includes:

[0041] S1: Determine whether the airport runway is a cement runway or an asphalt runway. If it is a cement runway, proceed to step S2; if it is an asphalt runway, proceed to step S3.

[0042] S2: Aspirate dust on the cement runway, and at the same time, select the traveling speed of laser degluing according to the laser energy density.

[0043] S3: Spray water on the asphalt runway to form a liquid film, and at the same time, select the traveling speed of laser degluing according to the laser energy density.

[0044] In this embodiment, the method of using laser for degluing is more environmentally friendly than the traditional chemical method, reducing the use of chemical agents and environmental pollution, and not generating pollutants such as dust; and it can select the traveling speed according to the laser energy density, which can optimize the degluing process, improve efficiency, and accurately control the degluing effect. This method designs pre-treatment methods of aspirating dust and spraying water to form a film respectively according to the different characteristics of cement runways and asphalt runways. The process of aspirating dust and laser degluing does not use chemical agents compared with the traditional degluing method, reducing environmental pollution, and at the same time avoiding the potential harm of chemical agents to the runway and surrounding soil and water sources. Through pre-treatment and precise degluing, this method can better maintain the flatness and roughness of the runway surface, reduce runway damage caused by improper degluing, and thus reduce subsequent maintenance costs and frequencies.

[0045] Optionally, in step S2, in the cement runway, the relationship equation between the traveling speed of laser degluing and the laser energy density is:

[0046] Y = 0.0038X - 0.005

[0047] Wherein, Y is the traveling speed of laser degluing, with the unit of m / s; X is the laser energy density, with the unit of J / cm 2 . This formula is the relationship between the numerical value of the traveling speed and the numerical value of the laser energy density, that is, it does not involve units.

[0048] In this embodiment, through experimental verification, the optimal degluing scheme for the cement runway is the high-pressure gas flow field-assisted continuous-pulse laser cleaning method. According to the integrated scheme of the 6000W continuous laser and the 2000W pulsed laser proposed by the present invention, the maximum laser degluing speed is 0.2686 m / s, and the degluing speed is better than the traditional airport runway cleaning method.

[0049] Optionally, in step S3, in the asphalt runway, the relationship equation between the traveling speed of laser degluing and the laser energy density is:

[0050] Y = 0.0038(X - 7.2) - 0.005

[0051] Wherein, Y is the traveling speed of laser debonding, with the unit of m / s; X is the laser energy density, with the unit of J / cm 2 . This formula represents the relationship between the numerical value of the traveling speed and the numerical value of the laser energy density, that is, it does not involve units.

[0052] Optionally, in step S3, the thickness of the liquid film is 2 mm to 3 mm.

[0053] Specifically, in step S3, the thickness of the liquid film is 2.5 mm.

[0054] In this embodiment, the optimal solution for asphalt runway debonding is the hydrodynamic field-assisted continuous-pulse laser cleaning method. During the cleaning process, the upper liquid film continuously absorbs laser energy and becomes in an overheated state. The vapor bubbles in the overheated liquid grow rapidly to form transient pressure waves, and the gas diffusion inside the concrete will accelerate bubble nucleation, resulting in the explosive evaporation of the liquid film layer. At this time, the generated pressure is equivalent to the cleaning force. When the cleaning force exceeds the adhesion of the glue black, the glue black is removed. Through experiments, it is verified that using normal temperature water with a liquid film thickness of 2.5 mm as the energy transfer medium is the most effective. According to the integrated scheme of the 6000W continuous laser and the 2000W pulsed laser proposed by the present invention, the maximum laser debonding speed is 0.2412 m / s, slightly lower than the debonding speed of the cement runway in step S2 of the present invention, but better than the traditional airport runway cleaning method.

[0055] Using a multi-field fusion laser debonding method for airport runways of the present invention, referring to the Laser surface cleaning technical specification (GB / T 41735 - 2022), the best cleaning state is that there is no obvious dirt and no damage on the surface after cleaning, the under-cleaning state is when the glue black is not completely removed, and the over-cleaning state is when the runway is damaged. The morphology of the airport runway after laser debonding is as Figure 2 shown. For the cement runway, in the under-cleaning state, reticulated rubber remains on the surface, and the color changes from the original pure black to light black; in the complete cleaning state, the rubber is completely removed, exposing some aggregates; in the over-cleaning state, all the coarse and fine aggregates are exposed and vitrified. For the asphalt runway, in the under-cleaning state, no obvious residual reticulated rubber is seen, only the thickness decreases and the color of the glue black becomes lighter; in the complete cleaning state, most of the rubber is removed, and only a small part of the rubber is ablated into black ash and adheres to the concrete surface, which has no impact on the asphalt pavement because it is originally pure black; in the over-cleaning state, the asphalt is pyrolyzed, and each aggregate of the concrete becomes loose, and the asphalt concrete ash will directly spall during over-cleaning.

[0056] The relationship equation between the traveling speed and the laser energy density in the laser debonding of the present invention is obtained by statistical fitting of on-site test data. The on-site test uses a 1064nm nanosecond ytterbium pulsed fiber laser cleaning machine (produced by IPG Photonics Corporation, USA, model YLPN-100-30x100-1000), and cooperates with an industrial robot (produced by KUKA Corporation, Germany, model KR16) to clean the airport runway. The laser cleaning area is 2cm * 2cm. The spot diameter of the laser is 1.2mm, and the repetition frequency is 10kHz.

[0057] The laser energy density H during cleaning corresponds to the intensity of laser irradiation, and the spot overlap rate a corresponds to the energy accumulation amount at the same position. Taking these two parameters as variables in the laser cleaning test, a complete laser debonding process database for the airport runway can be obtained. According to the following formula, the energy density H can be obtained:

[0058]

[0059] where P is the laser power, F is the repetition frequency, and A is the spot area.

[0060] By setting the laser power to 200W, 400W, 600W, 800W, 1000W, five parameters of the energy density H can be obtained: 1.8J / cm 2 、3.6J / cm 2 、5.4J / cm 2 、7.2J / cm 2 、9.0J / cm 2 .

[0061] The spot overlap rate (a) is divided into the longitudinal overlap rate and the transverse overlap rate. The longitudinal overlap rate = longitudinal filling pitch / spot diameter D, and the calculation formula for the transverse overlap rate is:

[0062]

[0063] where V x is the laser transverse scanning speed, F is the repetition frequency, and D is the spot diameter.

[0064] By setting the laser transverse scanning speed V x to 2400mm / s, 1800mm / s, 1200mm / s, 600mm / s, the transverse overlap rates obtained are: 0.8, 0.85, 0.9, 0.95. By setting the longitudinal filling pitch to 240μm (0.24mm), 180μm (0.18mm), 1200μm (0.12mm), 60μm (0.06mm), the longitudinal overlap rates obtained are 0.8, 0.85, 0.9, 0.95.

[0065] The same longitudinal and transverse lap rates are selected to fit the relationship equation between the travel speed of laser debonding and the laser energy density. Each cleaning object has 20 (5*4) cleaning process parameters. To ensure the universality of the results, the above experiments are repeated two to three times respectively. Referring to the Laser Surface Cleaning Technical Specification (GB / T 41735-2022), the best cleaning state is that there is no obvious dirt and no damage on the surface after cleaning.

[0066] As Figure 3 shown, when the laser energy density is 1.8 J / cm2, the spot lap rate should be at least 0.95 to completely remove the glue black at one time. At this lap rate, when the laser travels 60 μm longitudinally (longitudinal filling pitch), it takes (2 cm ÷ 600 mm) / s. At this time, the travel speed of laser debonding is 60 μm / (2 cm ÷ 600 mm) / s = 0.0018 m / s. By analogy, the cleaning efficiencies at 3.6 J / cm 2 、5.4 J / cm 2 、7.2 J / cm 2 、9.0 J / cm 2 are obtained and the formula Y = 0.0038X - 0.005 is fitted.

[0067] The laser will have energy loss in the transmission medium (water). According to the experimental results, the loss is about 7.2 J / cm 2 . Therefore, the relationship equation between the travel speed of laser debonding and the laser energy density in the above-mentioned cement runway is improved, and the relationship equation between the travel speed of laser debonding and the laser energy density in the asphalt runway is obtained as: Y = 0.0038(X - 7.2) - 0.005.

[0068] As Figure 4 shown, the embodiment of the present invention also provides an airport runway multi-field fusion laser debonding device, which mainly applies a method for multi-field fusion laser debonding of an airport runway in the above embodiment.

[0069] The device includes: a remote control electric platform 1, a pulsed laser 2, a continuous laser 3, a continuous-pulsed composite laser head 5, a dust removal system 6, a water chiller and a control module installed on the remote control electric platform 1. The remote control electric platform 1 is the traveling mechanism of the whole device, and its traveling speed is controlled by the control module.

[0070] The continuous-pulse composite laser head 5 is arranged at the rear of the remote-controlled electric platform 1; the output ends of the pulsed laser 2 and the continuous laser 3 are connected to the multi-light-source input port 14 on the continuous-pulse composite laser head 5, and a light output port 12 is arranged on the continuous-pulse composite laser head 5 for outputting laser with a laser energy density set by the user. Specifically, the pulsed laser 2 can be selected with a power of 2000W, and the continuous laser 3 can be selected with a power of 6000W. The two lasers are combined into one beam through a beam combiner and output to the continuous-pulse composite laser head 5, and then the laser with a maximum power of 8000W can be provided.

[0071] The dust removal system 6 is used to suck air on the airport runway to remove dust when the airport runway is a cement runway.

[0072] The water chiller is arranged at the front of the remote-controlled electric platform 1 and is used to spray water on the airport runway to form a liquid film when the airport runway is an asphalt runway.

[0073] According to an airport runway multi-field fusion laser debonding method in the above embodiment, the control module controls the output powers of the pulsed laser 2 and the continuous laser 3 according to the laser energy density set by the user, and sets the forward speed of the remote-controlled electric platform 1 according to the laser energy density.

[0074] Optionally, the water chiller includes a first water chiller 7 and a second water chiller 8. The dual water chiller structure can better adapt to complex working conditions in long-term and high-intensity airport runway debonding operations.

[0075] In this embodiment, the pulsed laser and the continuous laser are integrated and output through the continuous-pulse composite laser head. According to the laser energy density set by the user, the output powers of the two lasers can be flexibly adjusted to generate laser beams with different characteristics, meeting the debonding requirements for various stubborn rubber stains, greatly improving the debonding efficiency and quality. Moreover, for the cement runway, the dust removal system sucks air to remove dust, providing a clean working surface for laser debonding. For the asphalt runway, the water chiller sprays water to form a liquid film, reflecting the good adaptability of the device to runways of different materials.

[0076] Optionally, as shown in Figure 5, the dust removal system 6 is connected to the dust suction port 13 on the continuous-pulse composite laser head 5.

[0077] In this embodiment, both the dust suction port and the light output port are arranged on the continuous-pulse composite laser head, which can ensure that the dust suction area and the laser action area are highly coincident, reduce the scattering and absorption phenomena during the laser propagation process, provide a clearer propagation channel for the laser, ensure that the laser energy acts concentratedly on the runway pollutants, enhance the debonding effect, improve the laser energy utilization rate, and reduce unnecessary energy loss.

[0078] Optionally, the continuous-pulse composite laser head 5 is installed on the laser head adjustment mechanism 4, and the laser head adjustment mechanism 4 can swing between a vertical rest position and a horizontal working position; when the swing arm 10 is in the horizontal working position, the light outlet 12 faces the airport runway.

[0079] Specifically, the laser head adjustment mechanism 4 includes a swing arm base 9 and a swing arm 10. The continuous-pulse composite laser head 5 is installed on the swing arm 10, and the swing arm base 9 is installed on the remote control electric platform 1.

[0080] Optionally, as Figure 6 shown, a protective cover 15 is provided on the continuous-pulse composite laser head 5. The protective cover is of a cuboid structure. When the swing arm 10 is in the horizontal working position, the lower surface of the protective cover 15 contacts the runway and the upper surface is exposed to the open air. At the same time, a scale can be provided on the inner wall of the protective cover 15. When the liquid film thickness reaches the corresponding height, the nozzle of the water chiller is controlled to stop discharging water.

[0081] The continuous-pulse composite laser head 5 is connected to the swing arm 10 of the laser head adjustment mechanism 4 through a manual slide table adjustment 11. The manual slide table adjustment 11 can enable the continuous-pulse composite laser head 5 to slide on the swing arm 10. Furthermore, when in the horizontal working position, the focal length between the continuous-pulse composite laser head 5 and the runway can be manually adjusted to adapt to different airport runway structures.

[0082] In this embodiment, the laser head adjustment mechanism can swing between a vertical rest position and a horizontal working position, enabling the device to switch freely under different working conditions. When in a non-working state, placing the laser head in the vertical rest position can effectively reduce the space occupied by the device, facilitate transportation and storage, and also reduce the risk of accidental damage to the laser head. When operating, it is switched to the horizontal working position, and the light outlet accurately faces the runway, ensuring that the laser can act on the polluted area efficiently and improving the debonding efficiency.

[0083] Optionally, as Figure 7 shown, a protective cabin 17 is provided outside the remote control electric platform 1 to protect the components set on the remote control electric platform 1. The protective cabin 17 is provided with a first movable cabin door 18 and a second movable cabin door 19 to realize the opening and closing of the outer shell. A plug box 16 is also provided on the remote control electric platform 1 for externally connecting a mobile energy storage power vehicle.

[0084] In this embodiment, the protective cabin can effectively protect the components on the remote control electric platform, avoiding damage in the complex airport environment. The first movable cabin door and the second movable cabin door facilitate the staff to open the protective cabin for daily inspection, maintenance, and repair of the internal components. The plug box can be externally connected to a mobile energy storage power vehicle, getting rid of the limitation of the traditional fixed power supply.

[0085] Although the present invention is disclosed as above, the scope of protection of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the scope of protection of the present invention.
