Description

An airport runway glue remover Technical field

The invention relates to the field of runway glue removal equipment, in particular to an airport runway glue removal machine.

Background technique

Due to the friction of aircraft taking off and landing on the airport runway, the rubber tires are thermally degummed. This rubber layer is firmly attached to the runway. Over time, the rubber layer becomes thicker and thicker, causing the friction to decrease when the aircraft takes off and landing, and increases the taxiing distance of the aircraft. This makes it easy to run off the runway; moreover, the unevenness of the glue layer also aggravates the vibration of the aircraft taxiing.

At present, there are many glue removal equipment and methods, among which there are three main types: shot blasting, high pressure water gun washing and scraping. Among them, shot blasting has the best glue removal effect, but its cost is high and the glue removal efficiency is low. , the scraping and polishing process uses a brush roller and a scraper and is driven by a large driving equipment. It has the fastest glue removal speed, but the worst effect. Comparing the high-pressure water gun glue removal method with the above two glue removal methods, it can take into account both efficiency and At the same time, high-pressure water gun glue removal is smaller, lower cost and easier to operate than the above two glue removal equipments. Therefore, high-pressure water gun glue removal is also the most widely used.

There are many high-pressure water gun glue removal equipment at this stage. The application number is: 202123233486.8, and the patent name is: a new type of airport runway glue removal and cleaning device. By installing a cross, and the high-pressure nozzle 3 is installed tiltedly on the cross, When the high-pressure nozzle is cleaning, the reaction force pushes the cross to rotate so that the cleaning area becomes a circle, thereby improving the cleaning effect. However, there are disadvantages in this type of equipment, that is, when high-pressure water washes the ground, the water flow impacts the ground and produces a reaction. If this reaction causes the device to move, it will reduce the scouring effect of high-pressure water on the ground to a certain extent. Therefore, this reaction force must be resisted so that the high-pressure water flow continues to spray on the ground to achieve an efficient scouring and clearing effect. Today's equipment Most of the time, artificial force is used to resist the reaction force, which requires workers to exert a large driving force when operating the equipment. The continuous cleaning operation undoubtedly consumes a lot of physical strength of the workers, resulting in labor High strength, while construction efficiency also slows down.

beneficial effects

The nozzles on both sides of the middle U-shaped tube of this device are inclined inward and downward and are symmetrical.
