[0011] Through the above technical solution, when passing through an area where the road surface slope changes, the bracket will slide up and down in the sliding plate, driving the pointer on the angle display disk to deflect, thereby measuring the road surface slope.

[0012] As a further improvement of the above solution, a support column is fixedly connected to the bottom of the mounting plate, a roller is fixedly connected to the bottom of the support column, and a handle is fixedly connected to one end of the mounting plate.

[0016] The utility model sets a bracket, and the sliding of the bracket drives the sliding plate, the fixed box and the internal spring above, and drives the rotating shaft to rotate through the connecting plate, so that the pointer fixed on the surface of the rotating shaft is deflected on the angle display disk. The angle indicated by the pointer is the measured road surface slope, and the above-mentioned device is symmetrically arranged. The user can observe the slope data of different heights on one side, and the slope of the highway road surface can be accurately measured by measuring the contact between the roller and the road surface, and the deflection of the pointer on the angle display disk. In order to obtain more accurate measurement results, multiple measurements can be performed at different positions and the measurement data can be recorded. The measuring instrument has a simple structure and is easy to operate. It only needs to be placed on the road surface and pushed to perform measurements, without complicated settings or calibration, which enables construction personnel to quickly and easily obtain slope data.
