Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0021] refer to Figure 1 to Figure 5 , The road surface irregularity piezoelectric dynamic detector includes a wheel 1, a mandrel 2, a piezoelectric ring 3 and a weight 4.

[0022] The wheel 1 is a standard automobile wheel, and the piezoelectric ring 3 is a ring-shaped part made of piezoelectric ceramics. The outer ring of the piezoelectric ring 3 is set inside the inner hole of the wheel 1 and is connected with the inner hole of the wheel 1 through an interference fit. The shaft 2 is a stepped cylindrical part, the two ends and the middle of the mandrel 2 are processed with threads, the mandrel 2 passes through the inner hole of the piezoelectric ring 3 and is connected with the piezoelectric ring 3 with clearance fit, and the end surface of one side of the piezoelectric ring 3 It is in contact with the end face of the shaft shoulder in the middle of the mandrel 2,...

Abstract

The invention discloses a piezoelectric dynamic detector for the irregularity of a road surface. The piezoelectric dynamic detector aims at solving the problems that at present, the irregularity of the road surface is mainly measured through a meter ruler manually, efficiency is low, accuracy is poor, and the labor intensity of workers is large. The piezoelectric dynamic detector for the irregularity of the road surface is mainly composed of a wheel (1), a mandrel (2), a piezoelectric ring (3) and counter weights (4). The piezoelectric dynamic detector for the irregularity of the road surface is simple in structure, high in detection accuracy, small in accumulation error, complete in function, easy and convenient to operate, easy to install, high in universality, lower in cost, reliable in performance and capable of meeting the requirement of a road surface detection industry for detecting the irregularity of the road surface.

Description

technical field [0001] The invention relates to a detection device in the field of road detection, more specifically, it relates to a piezoelectric dynamic detector for road surface irregularity. Background technique [0002] In order to ensure the safe driving of automobiles and realize the efficiency, comfort and safety of road transportation, the measurement of road surface irregularities is one of the main inspection items in the field of road inspection. At present, the measurement of road irregularities is mainly based on manual meter measurement, which has low efficiency, poor accuracy, and high labor intensity for staff. The use of piezoelectric effect measurement technology to detect road irregularities is expected to solve the above technical bottlenecks due to its characteristics of fast, accurate and high reliability, and is of great significance for improving the measurement accuracy and automation of road irregularities. In the present invention, the piezoelec...
