Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection equipment, in particular to a flatness detector. Background Art

[0002] When constructing a road, in order to ensure the flatness of the road, it is often necessary to use a flatness tester to detect the flatness of the road. The utility model patent with patent application number CN202223426480.7 discloses a flatness tester for road construction measurement. The spring piece presses the moving plate tightly, and the moving plate slides inside the slide groove through the slider. The moving plate drives the airbag to move, and the airbag clamps the surface of the detection instrument to prevent movement. The fixed sleeve can strengthen the protection of the detection movement, so that the flatness tester achieves a good protective effect, replacing the existing method of placing it on the top of the flatness tester. , thereby achieving good protection. When the flatness detector is moving, the detection instrument will not shake, which improves the safety of the flatness detector. According to the disclosed technical solution, when the existing flatness detection equipment is used, on the one hand, it can only perform overall road flatness detection work. Some small concave surfaces and convexities are easily not detected under the rigid support of the wheels, which is not conducive to ensuring the reliability of road flatness detection. On the other hand, when detecting the flatness of the road, it is not possible to effectively calibrate the flatness section, which is not conducive to adjusting the flatness index according to different road requirements.

[0013] Beneficial effects: 1. When the flatness tester is in use, the motor is turned on, and the motor moves through the outer tires and drives the six wheels to move through two motors, which facilitates the self-movement of the equipment. When the road as a whole tilts in the front-to-back direction, the front and rear longitudinal beams are deflected front-to-back through the inner side of the ball groove in the cross beam through the card ball, and then the button on the longitudinal beam is squeezed to the bottom of the cross beam, so that the corresponding front and rear indicator lights on the battery are all lit.
