Description

A high-frequency induction and laser composite degumming device for airport pavement

technical field

The invention belongs to the technical field of laser cleaning equipment, and in particular relates to a high-frequency induction and laser compound glue removing device for airport pavement.

Background technique

For an airport, the runway is a critical facility for its operations. Aircraft tires contact the runway surface due to friction during high-speed landing, resulting in high temperature, which will instantly melt the tire rubber to form a rubber melt and adhere to the road surface texture, with the increase of friction times With the passage of time, the rubber layer of the road surface is continuously thickened, resulting in a decrease in the friction coefficient of the road surface, thereby affecting the braking performance of the aircraft, especially when the road surface is wet, the viscosity of the rubber on the runway reduces the friction force significantly , which will directly affect the safe landing of the aircraft. Therefore, major airports need to clean the runway from time to time every year, and ensure that the friction coefficient of the road surface is not less than 0.5, so as to avoid accidents.

At present, the most commonly used degumming methods are chemical degumming method, high-speed impact method and mechanical polishing method. The chemical degumming method, as the name implies, is to spray the degumming liquid on the wheel track, change the original polymer structure of the wheel track to make it soft, and then loosen the wheel track under the action of scraping and friction, and finally under a certain high pressure. Under the action of water, the soft and loose wheel tracks on the road surface are removed. However, through the actual investigation, it is found that this method has a great negative impact on the road surface, mainly including (1) if the residual wheel track residue on the road surface is not cleaned up in time, it will pollute the road surface environment and be easily sucked into the engine and cause damage to the road surface. damage the leaves. (2) Chemical degumming agent will chemically react with asphalt in the process of biodegradation, which will also lead to the damage of asphalt concrete pavement. (3) When the thickness of the wheel track is thick, the cleaning of the wheel track in the groove is not thorough enough. (4) When there is residual glue removal liquid, it will corrode the marking line lights on the road surface and the tires of aircraft and all driving vehicles to a certain extent. (5) When using the chemical degumming method, the airport runway must be completely closed, which affects the operation of the flight. (6) The chemical degumming solution is expensive and has a small application range. The high-speed impact method is to use a high-speed rotating small-radius steel device to impact, rub, shovel and other operations on the pavement wheel track, so that the wheel track becomes loose and fine particles. box, you can clean up the glue in time. However, due to the small particles of the residual wheel track, if it is not cleaned up in time, it will cover the texture structure of the pavement surface again and reduce the degumming efficiency. And due to the direct action of external force, its strength is relatively large, if the operation is improper, it will damage the asphalt concrete pavement. At the same time, since this method can only be carried out on the dry road surface, it will be affected by the weather. The mechanical grinding method is mainly to remove the wheel marks on the surface of the pavement with the help of a grinder and other equipment. However, for the grooved cement concrete pavement, the surface layer is worn out in order to restore the texture. At this time, the size of the groove has changed. If the grooved pavement can still maintain a good drainage channel, it must be re-grooved. Increased capital investment. Therefore, there is currently a lack of an airport pavement degumming device that has a wide range of applications, less damage to the pavement, thorough removal of waste, and can effectively improve the efficiency and quality of degumming.

2. If there is an external power supply near the glue removal site, connect the external power supply and use the external power supply to supply power to the electrical components of the device, otherwise use the battery to supply power to the electrical components of the device;

3. Determine whether the operation object is a small-area glue point or a large-scale glue surface. If it is the former, use a small high-frequency induction cleaning head 9, turn on the equipment switch on the console 3, and use the sensor temperature setting button to set Appropriate working temperature of the first high-frequency sensor 20; if it is the latter, use a larger size composite heat source cleaning head 8, use the laser parameter setting button to select the appropriate laser parameters of the laser 26, and use the sensor temperature setting button to set The suitable working temperature of the second high-frequency sensor 25; these parameters will be displayed on the display screen 2 in real time;
