A road surface survey device for detecting broken manhole cover

Abstract

The invention discloses a road surface surveying device for detecting the damage of a manhole cover. The lower end is connected with a base plate, the center of the base plate is provided with a through hole, the two ends of the lower surface of the base plate are symmetrically connected with moving wheels, the inner wall of the rack box above the base plate is symmetrically connected with a fixed bracket, and a camera is installed at one end of the fixed bracket. The road surface surveying device for detecting the damage of the manhole cover proposed by the present invention is provided with a frame box body, equipped with moving wheels and push rods, which facilitates the movement of the frame box body, and uses an ultrasonic flaw detector to detect whether there is a crack in the manhole cover. Retrofitting manhole covers and installing monitoring sensors is low-cost and easy to implement. General manhole covers can be tested. Using cameras and display screens, it is convenient to observe the surface conditions of manhole covers. It does not require operators to bend over to confirm, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of manhole cover surveying, in particular to a road surface surveying device for detecting manhole cover damage. Background technique [0002] If the damaged manhole cover is not replaced in time, it will endanger the safety of passing pedestrians and vehicles, and even endanger people's lives in severe cases; and in the management of a large number of manhole covers, the damage caused by seriously damaged manhole covers is even greater than that of damaged manhole covers. Slight manhole cover. Therefore, all the damaged manhole covers are prioritized according to the degree of damage, and then the most serious manhole covers are repaired, which can minimize various safety accidents caused by manhole cover damage and realize intelligent and refined manhole covers. manage. [0003] Existing technology can mainly be divided into two categories to the detection of manhole cover breakage. One is to use a rede...

AI Technical Summary

Problems solved by technology

One is to use a redesigned special manhole cover, which needs to be replaced all the manhole covers, and the other is to detect the damage of the manhole cover by adding sensors to the bottom of the manhole cover, which requires all the existing manhole covers to be turned up and sensors installed The cost of these two types of detection is high, and the detection circuit needs to be connected, the installation is complicated, and the cost of replacement will also increase after the manhole cover is damaged.
