Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a road surface smoothness measurement device, which has the detection speed block, and the measurement device is not easy to shake when being dragged by a vehicle, and the measured road surface can be cleaned during the measurement process, etc. , to solve the problem that when the vehicle is dragged, the connection between the walking frame and the body of the measuring device is relatively fixed. When the vehicle shakes, the measuring device will vibrate, which will affect the measurement accuracy. Moreover, there are foreign objects such as stones on the newly built road, which will also cause the measuring instrument to detect The problem of reduced accuracy

Abstract

The invention relates to the technical field of machine pulsation controllers, and discloses a road surface flatness measuring device which comprises a detection host, a plurality of infrared sensors, a plurality of displacement sensors and a rectangular frame, wherein two vertical rods are fixedly connected to the edge of the upper end of the rectangular frame, and a transverse plate is fixedly connected to the upper ends of the two vertical rods together. The upper end of the transverse plate is fixedly connected with the lower end of the detection host, the lower end of the transverse plate is fixedly connected with a plurality of displacement sensors, a supporting rod is fixedly connected to the center of the rear edge of the upper end of the rectangular frame, and a fixing frame is fixedly connected to the upper side of the rear end of the supporting rod. According to the road surface flatness measuring device, flexible connection between the measuring device and a traction vehicle can be achieved, the situation that the working precision of the measuring device is affected by shaking of the vehicle is prevented, the measuring device can be rapidly lifted to facilitate hauling after measurement is completed, and obstacles at the upper end of a measured road surface can be cleaned when necessary.

Description

technical field [0001] The invention relates to the technical field of pulsation controllers, in particular to a road surface smoothness measuring device. Background technique [0002] The roughness of the road surface is one of the main technical indicators for evaluating the quality of the road surface. It is related to the safety and comfort of driving, the size of the impact force on the road surface and the service life. The uneven road surface will increase the driving resistance and cause additional damage to the vehicle. This kind of vibration will cause driving bumps, affect the speed and safety of driving, and affect the stability of driving and the comfort of passengers. At the same time, the vibration will also exert an impact on the road surface, thereby aggravating the damage of the road surface and automobile parts, the wear of tires, and increasing the consumption of fuel. Moreover, the uneven road surface will also accumulate rainwater, which will accelerat...
