Crawler-type intelligent automatic pavement detection device

Abstract

The invention discloses a crawler-type intelligent automatic pavement detection device. The crawler-type intelligent automatic pavement detection device comprises a crawler-type vehicle body, wherein the crawler-type vehicle body is provided with a control system, a nondestructive inspection system and an operation mechanism; the operation mechanism is mounted on the crawler-type vehicle body; the nondestructive inspection system is connected with the operation mechanism; the control system is electrically connected with the operation mechanism; the control system is electrically connected with the nondestructive inspection system; the nondestructive inspection system comprises a resistivity meter; and the operation mechanism comprises a telescoping mechanism and the resistivity meter is connected with the telescoping mechanism. With the adoption of the crawler-type intelligent automatic pavement detection device disclosed by the invention, intelligent detection can be realized; the device does not need to be manually driven, so that the detection safety and the accuracy of detection data are improved; a plurality of types of nondestructive inspection sensors are integrated and comprehensive evaluation on pavement conditions (including inner conditions) can be realized in one step; and the detection efficiency is greatly improved and the influences on road passing are also reduced.

Description

technical field [0001] The invention relates to a pavement detection device, in particular to a crawler-type intelligent device for autonomous detection of pavement. Background technique [0002] After the expressway is completed, in order to ensure the safety and efficiency of traffic, it needs regular maintenance. With the rapid increase in the mileage of expressways in China and the increase in the service life of the roads, expressways have entered a period of equal emphasis on construction and maintenance. Expressways with more than 50,000 kilometers have generally entered the normal maintenance period after the defect liability period, and the overall personnel scale of the maintenance industry has grown rapidly. With the "Twelfth Five-Year Road Maintenance and Management Development Outline" of the Ministry of Communications, the proportion of major and medium repairs has been increased from 13% to 17%, and the proportion has increased by nearly 30%. In 2015, nearly ...

Problems solved by technology

At present, the detection and evaluation of road surface conditions mainly rely on manual visual inspection, which mainly depends on experience, and the detection accuracy is poor

The alternative is to use manual instrument detection, which is better than visual data accuracy, but there are also the following problems: First, manual data collection is easily affected by manual operation errors, data accuracy cannot be guaranteed, and personal safety No guarantee; second, the rate of manual inspection is low, requiring a lot of manpower, labor-intensive and inefficient, and the inspection time is long, which affects...
