Embodiment 1

[0040] A multifunctional inspection vehicle, such as figure 1 As shown, including the vehicle body, 3D scanner and drop weight deflectometer.

[0041] The three-dimensional scanner is installed at the rear end of the vehicle body, which includes a CCD camera, a line laser emitter and an angle sensor. A mounting frame is fixedly installed at the rear end of the vehicle body, and the CCD camera is fixedly mounted on the mounting frame. Both the line laser emitter and the angle sensor are arranged on the chassis at the rear end of the vehicle body, and the line laser emitter and the angle sensor are arranged in a figure-eight shape. When in use, the line laser emitter projects a linear laser onto the road surface to be inspected, and the strip-shaped light strip is modulated by the three-dimensional information of the road surface and then imaged on the CCD camera to obtain data information of a longitudinal section, while the inspection vehicle During the driving process, with ...

Embodiment 2

[0055] refer to Figure 6 , The difference from Embodiment 1 is that four safety locks are fixedly installed on the frame, and are arranged in groups of two on both sides of the hammer drop device.

[0056] The safety lock includes a base, a connecting shaft, a support grip, a torsion spring and a support hydraulic cylinder, and the base is fixedly installed on the frame.

[0057] The connecting shaft is fixedly installed on the base, and the supporting gripper is connected to the rotating shaft so that it can rotate around the rotating shaft. There is a screw thread at the end of the rotating shaft, and a limit cover is threaded on the rotating shaft. Through a limit cover Axially limit the support gripper on the rotating shaft.

[0058] The torsion spring is sleeved on the connecting shaft, and a receiving groove is provided on the opposite side of the supporting handle and the base. One end of the torsion spring is inserted into the receiving groove on the supporting handl...

Abstract

The invention discloses a multifunctional detection vehicle. The multifunctional detection vehicle comprises a vehicle body and a three-dimensional scanner mounted at the rear end of the vehicle body,wherein a mounting hole penetrating through a chassis of the vehicle body is arranged in the vehicle body, and a drop hammer deflectometer is arranged on the mounting hole; the drop hammer deflectometer comprises a door frame-shaped support and a drop hammer device; two lifting hydraulic cylinders are arranged on the door frame-shaped support; a bearing plate and two connecting arms fixed on thebearing plate are arranged on the drop hammer device; and piston rods of the two lifting hydraulic cylinders are respectively connected with the two connecting arms. According to the multifunctional detection vehicle, the drop hammer deflectometer and the three-dimensional scanner are integrated into the detection vehicle together, and a unique control system is matched, so that the road surface condition is detected in the running process of a vehicle at the speed of one hundred kilometers.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a multifunctional detection vehicle. Background technique [0002] At present, with the improvement of detection technology, more and more road inspection vehicles have appeared, which integrate photoelectricity, IT and 3S technology through the platform of motor vehicles. In the normal driving state of the vehicle, it can automatically complete the data collection, analysis, classification and storage of road surface images, road surface shapes, three-dimensional images of road facilities, smoothness and road geometric parameters. It provides an effective means of data collection for the detection of damage, flatness, rutting, and road safety hazards of highways, high-grade highways, urban municipal roads, and airport runways, as well as the digital management of road ancillary facilities. [0003] The functions of the existing inspection vehicles are not comprehensive e...
