Description

Road surface detection auxiliary device

Technical Field

The application relates to the technical field of auxiliary devices, in particular to a pavement detection auxiliary device.

Background

In the prior art, as the flatness of the road surface is related to the safety of driving, comfort and the size and service life of impact force applied to the road surface, the uneven road surface can increase driving resistance and cause the vehicle to generate additional vibration. The vibration effect can cause the driving jolt, influence the speed and the safety of the driving, and influence the driving stability and the comfort of passengers. At the same time, the vibration effect can also apply impact force to the road surface, thereby increasing the damage of the road surface and the parts of the automobile and the abrasion of the tyre and increasing the consumption of oil. In addition, for the road surface which is positioned in the water network area and is uneven, rainwater is accumulated and water damage of the road surface is accelerated, so that the road surface needs to be subjected to flatness detection operation regularly;

However, in the existing detection mode, the measuring instrument is usually placed in a rear compartment of the pick-up truck, then the pick-up truck drives over the measured road surface, the measuring instrument collects the amplitude of the pick-up truck during the driving, and the flatness value of the road surface is converted according to the amplitude, but because the pick-up truck is provided with a damping mechanism and the engine is a vibration source, the amplitude collected by the measuring instrument has a larger error, so that the measured road surface flatness has a larger deviation from the real flatness, therefore, how to design a device for assisting the measuring instrument in measuring the road surface flatness is used for reducing the measurement error, and the measuring accuracy can be effectively improved.

Disclosure of utility model

The application aims to solve the problems that when the existing road surface flatness is detected, a pick-up truck carries a measuring instrument to drive over the road surface to be measured, however, the amplitude data of the road surface obtained by the measuring instrument can be influenced by vibration of an engine of the pick-up truck and a damping mechanism of a vehicle, so that the error of measured data obtained by the measuring instrument is larger.

In order to solve the technical problems, the application provides a pavement detection auxiliary device, which comprises a frame for supporting a foundation, wherein a traction assembly which is convenient for carrying out traction operation on the frame is arranged in front of the frame, a wheel assembly which is used for walking along the ground is arranged below the frame, the frame is divided into a main frame and an auxiliary frame which are connected with each other in a sliding way, and an auxiliary wheel assembly which can be contacted with the ground to eliminate resonance is additionally arranged on the upper part of the auxiliary frame.

Because the auxiliary device is designed with the traction assembly, the wheel assembly, the main frame, the auxiliary frame and the auxiliary wheel assembly, the auxiliary device capable of bearing the measuring instrument can be independently arranged, and the measuring data errors caused by engine vibration or a vehicle damping mechanism can be effectively removed, so that the problem that the measuring data errors obtained by the measuring instrument are larger when the measuring instrument is driven through a road surface to be measured through a pick-up truck when the road surface flatness is detected in the prior art, and the amplitude data of the road surface obtained by the measuring instrument can be influenced by the engine vibration of the pick-up truck and the vehicle damping mechanism is solved.
