Description

Technical Field

[0001] The present application relates to the technical field of levelness measurement, and in particular to a road levelness measuring device. Background Art

[0002] Road flatness is one of the main technical indicators for evaluating road quality. It is related to driving safety, comfort, the impact force on the road surface and its service life. Uneven road surfaces will increase driving resistance and cause additional vibrations in vehicles. This vibration will cause driving bumps, affect driving speed and safety, and affect driving stability and passenger comfort. At the same time, vibration will also exert impact force on the road surface, thereby aggravating damage to the road surface and automobile parts, wear of tires, and increasing fuel consumption. Uneven roads will also accumulate rainwater, accelerating damage to the road surface. In road and bridge construction, it is necessary to measure the flatness of the ground to ensure the flatness of the ground.

[0003] At present, in order to maintain the flatness of the ground, it is necessary to pay continuous attention to the flatness of the ground and use a flatness measuring device to measure the flatness of the road. The usual flatness measuring device is a rectangular plate. The two ends of the rectangular plate are strictly controlled to be level. One side of the rectangular plate is abutted against the road. The position where the road does not abut against the rectangular plate, that is, the flatness does not meet the specifications, is marked with a marker, and the rectangular plate is moved on the road. The marks are continuously recorded. After the final measurement, the marked position can be repaired.

[0004] Regarding the above-mentioned related technologies, the inventor believes that during the measurement process, only the position of the depression can be detected, but the specific data of the depression cannot be measured. It is not easy to control the amount of material used during repair, and when marking with a marker, the marker cannot be placed at the bottom of the rectangular plate, and the specific position of the depression cannot be marked. Therefore, during the repair process, the amount of raw materials and the repair position are not easy to control, and repeated verification is required, resulting in the defect of low construction efficiency. Summary of the invention

[0005] In order to achieve the effect of improving construction efficiency, the present application provides a road levelness measuring device.

[0006] The present application provides a road levelness measuring device that adopts the following technical solution:

[0007] A road levelness measuring device comprises a calibration plate, a wedge block and a calibration bubble. The calibration bubble is fixed on one side of the calibration plate and is used to judge whether the calibration plate is in a horizontal state. The wedge block is arranged on a side of the calibration plate away from the calibration bubble. The wedge block and the calibration plate are slidably connected. A scale is arranged on the inclined surface of the wedge block. When measuring the flatness of the road, the wedge block slides between the road and the calibration plate, and the scale reading is the depth of the depression.

[0008] By adopting the above technical solution, when it is necessary to measure the horizontality of the road, one end of the calibration plate is abutted against the road, and the corresponding other end is rotated until the calibration bubble is in a horizontal state, and the wedge block is slid until the wedge block can no longer slide, and the scale on the wedge block is read, that is, the depth of the depression at the measuring position, and it can be marked with a pen, and repairs can be carried out according to the mark and the depth, and the corresponding raw materials can be taken, so as to avoid the difficulty in controlling the required amount of raw materials and avoid repeated construction, thereby achieving the effect of improving construction efficiency.

[0017] Optionally, a spring is fixed between the connecting block and the marking pen, and the length direction of the spring is the same as the length direction of the marking pen. When the road flatness is measured, the spring is always in a compressed state.

[0018] By adopting the above technical solution, when measuring the flatness of the road, the spring is always in a compressed state, and the marker pen is always in contact with the road.

The length of the additional plate 11 is the same as the width of the calibration plate 1. The projection of the additional plate 11 in the horizontal plane is completely placed within the projection of the calibration plate 1 in the horizontal plane. A second slider 14 is fixed to one end of the additional plate 11. The second slider 14 is embedded in the second slide groove 13. The second slider 14 slides in the second slide groove 13.

The pointed cone end of the wedge block 2 slides in from one end of the additional plate 11, and the additional plate 11 at the sliding end is close to the second slide groove 13. A scale 21 is set on the inclined surface of the wedge block 2. When measuring the flatness of the road, one end of the calibration plate 1 is abutted against the road, and the other end of the calibration plate 1 is rotated until the calibration bubble 3 is horizontal, and then the pointed cone end of the wedge block 2 is slid between the additional plate 11 and the road until the wedge block 2 can no longer slide, and the inclined surface of the wedge block 2 is abutted against the additional plate 11. At this time, the reading of the scale 21 plus the thickness of the additional plate 11 is the depth of the road depression.
