Airport pavement plasma degumming device

Abstract

An airfield pavement plasma glue removal device comprises a DC power supply, a plurality of high voltage bags connected in series, a plasma emitting gun, an oxygen cylinder and a control switch. The negative electrode of the DC power supply is connected with the negative electrodes of the input ends of the high voltage bags connected in series through the control switch. The positive electrode of the DC power supply is connected with the positive electrodes of the input ends of the high voltage bags connected in series. The positive electrodes and the negative electrodes of the output ends of the high voltage bags connected in series are connected with the positive electrode and the negative electrode of the plasma emitting gun respectively. The top end of the plasma emitting gun is connected with the oxygen cylinder. The airfield pavement plasma glue removal device has the advantages that a glue layer accumulated on a pavement is gasified through the high activity of plasmas, and therefore the glue layer is thoroughly stripped away from the pavement, and a cement concrete pavement can not be influenced; only the power supply and the oxygen cylinder need to be arranged, no heavy high water pressure generating device is needed, the advantages of being light and convenient to use, high in glue removal speed and low in device manufacturing cost are achieved, and the glue removal efficiency of the airfield pavement can be greatly improved; glue accumulated on the pavement is gasified and stripped away from the pavement through oxygen in a plasma state, and therefore the cleanout fluid recovery process needed when glue is removed through high-pressure water is omitted, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of airport auxiliary facilities, in particular to a plasma degumming device for airport pavement. Background technique [0002] The friction performance of airport pavement is an important guarantee for the safe take-off and landing of aircraft. The reduction of the friction coefficient of the road surface will increase the taxiing distance of the aircraft, which will easily cause the aircraft to overrun the runway. [0003] The position of the main wheel track on the touchdown zone of the airport runway will generate a lot of heat due to the intense friction between the wheel and the road surface when the plane lands, resulting in thermal degumming of the rubber wheel, and this glue layer will be firmly attached to the runway, causing the plane to take off and land The coefficient of friction decreases. According to the "Civil Airport Operation Safety Management Regulations", the airport management agency...

AI Technical Summary

Problems solved by technology

However, the current degumming technology often causes the road surface to drop sand, thereby reducing its structural depth and macroscopic friction coefficient. hard to improve

In addition, the high cost and huge equipment of the commonly used glue removal equipment are also the current shortcomings of this industry.
