Description

Technical Field

[0001] The utility model relates to the field of highway maintenance detection deflection measurement, in particular to a deflection measuring device for highway maintenance detection. Background Art

[0002] Deflection is one of the important technical indicators for highway design and evaluation of highway engineering quality. It reflects the overall strength of each layer of the road surface. If the difference in deflection is too large, the deformation will be greater and the various layers of the road surface will be more likely to crack. The deflection value of the road surface is generally obtained through deflection detection, so a deflection measuring device is required. Among them, the "A deflection measuring device for highway detection" disclosed in the application number "202021768504.5" is also an increasingly mature technology. It "rolls on the ground with a rubber wheel. If the ground height changes, under the action of the spring, the rubber wheel will move up and down against the measuring guide rod in the spring. This display is used to reflect the deflection of the road surface. It is simple and quick". However, the measuring device has the following defects during use: the measuring device can indeed measure the deflection of the road surface through the rubber wheel couple, spring and measuring guide rod, but the accuracy measured only by the measuring guide rod is poor, so there are certain limitations in use. Based on this, it is necessary to provide a measuring device that can improve the accuracy of temperature difference measurement and thereby enhance practicality. In addition, the overall structural stability of the measuring device is weak, so there may be a risk of tipping over during use. Based on this, it is necessary to provide a measuring device that can improve the stability of use. Utility Model Content
