Height sensing control system of bituminous pavement maintenance heater

Abstract

The invention discloses a height sensing control system of a bituminous pavement maintenance heater. The height sensing control system of the bituminous pavement maintenance heater comprises a pavement heater, a height sensor, a main controller, a lifting mechanism and a heating switch circuit, wherein the pavement heater is used for heating and maintaining a bituminous pavement; the height sensor is used for collecting the value of the height from the pavement heater to the bituminous pavement; the main controller determines the pavement level according to a collected height signal and sends out a corresponding executive command; the lifting mechanism executes the executive command output by the main controller and drives the pavement heater to ascend or descend automatically to regulate the height; the heating switch circuit is controlled by the main controller to decide whether the pavement heater stops acting; the height sensor, the lifting mechanism and the heating switch circuit are respectively connected with the main controller; the pavement heater is connected with the lifting mechanism and the heating switch circuit respectively. The height sensing control system of the bituminous pavement maintenance heater provided by the invention can automatically and accurately control the terrain clearance of the pavement heater, can improve the use safety and operation convenience effectively, and has the advantages of simple and reasonable structure, low manufacture cost, high intensity, flexibility in operation and long service life.

Description

technical field [0001] The invention relates to the field technology of asphalt road maintenance equipment, in particular to a height adjustment system of a road surface heater of an asphalt road surface maintenance vehicle. Background technique [0002] Common asphalt road maintenance vehicles use ordinary travel switches to control the height of the road surface heater. Due to the harsh working environment, the road surface heating area is easily hit and dragged when moving close to the ground, which will cause the travel switch to be reported as broken, seriously affecting the road surface. normal operation of the heater. Especially when the pavement heater is a microwave heater, in order to prevent the heated pavement from burning the body of the microwave heater and to ensure that the microwave leakage rate remains within a safe range, the pavement heater needs to be kept at a certain height from the pavement. Contents of the invention [0003] In view of this, the p...
