Portable annular crack detector for road detection

Abstract

The invention discloses a portable annular crack detector for road detection, which comprises a detection vehicle, moving wheels are arranged on the outer surface of the lower end of the detection vehicle, a buffer assembly is arranged between the moving wheels and the detection vehicle, the number of the moving wheels is three, and the moving wheels are triangularly distributed at the bottom end of the detection vehicle. A cavity is formed in the outer surface of the lower end of the detection vehicle, one set of moving wheels are located below the cavity, a transmission assembly is arranged in the cavity, a support is fixedly connected to the rear end of the annular inner surface of the detection vehicle, an electric telescopic machine is fixedly connected to the upper end of the support, and a sliding rail is formed in the outer surface of the support in a penetrating mode. According to the steering control device for the detection vehicle, steering control over the detection vehicle is completed through mutual cooperation of the first motor, the first gear and the second gear, and driving is achieved through mutual cooperation of the second motor, the belt, the auxiliary wheel, the driven wheel and the driving wheel.

Description

technical field [0001] The invention relates to the field of road detection, in particular to a portable annular crack detector for road detection. Background technique [0002] At present, urban roads, highways and other pavements are all paved with asphalt to form asphalt pavements. Due to the effect of traffic loads and the influence of natural factors, cracks will occur on the asphalt pavement. If the cracks are not repaired in time, there will be pits on the pavement. Causes deeper damage to asphalt pavement, and also affects driving safety. [0003] However, when the existing technology is actually used, in order to detect cracks on the road, the existing road detection equipment can be used to evaluate the road service life and road usage through the detection results. Detection equipment is usually installed under the cart. However, there are cracks in the road surface. When the inspector pushes the vehicle, the vehicle will be bumpy, which will lead to errors in th...

Problems solved by technology

[0002] At present, roads such as urban roads and expressways are paved with asphalt to form asphalt pavement. Due to the effect of driving load and the influence of natural factors, cracks will appear on the asphalt pavement. If the cracks are not repaired in time, road pits will occur, thus Causes deeper damage to asphalt pavement and also affects driving safety

[0003] However, when the existing technology is actually used, in order to detect the cracks on the road, the existing road inspection equipment can evaluate the service life of the road and the road use condition through the detection results. Usually, the detection equipment is installed under the cart. However, due to cracks on the road surface, when the inspector pushes the vehicle, the vehicle will bump, which will lead to errors in the detection value. At the same time, the need for personnel to push will also cause uneven measurement speed, and the gravel inside the crack will also affect the detection. The result makes an impact
