Abstract
Description
Technical Field
[0001] The utility model relates to the field of road construction, and more specifically, to a distance measuring device for road construction. Background Art
[0002] The road mainly includes motor vehicle lanes, non-motor vehicle lanes, sidewalks, median strips and side strips. The width of each component is an important control parameter in the road construction process. If the width of the component does not meet the design requirements, it will at least affect the driving comfort and traffic efficiency of motor vehicles and the smoothness of the slow-moving system. At worst, it will easily cause traffic safety accidents. After the road construction is completed, the supervision personnel need to test the width of each component of the road to verify whether it meets the design documents.

The width measuring device for municipal road construction is provided with a sliding rod, a slider and a scraper ring. During the process of retracting the measuring rope, since the conical inner wall of the scraper ring will fit with the outer surface of the measuring rope, when the measuring rope is retracted through the scraper ring, a large amount of dust and impurities adhered to the surface of the measuring rope can be scraped off, making the measuring rope cleaner, and since the slider is slidably connected to the two sliding rods, the staff can move the slider left and right on the sliding rod, so that after the measuring rope is retracted, it can be evenly wound on the surface of the rope roller, making the fixed cylinder more tidy, avoiding the situation where dust adheres to the measurement process and is inconvenient to use.
[0004] However, in actual use, the existing distance measuring equipment has a relatively simple function and is mainly used to test the width and distance of the road surface. When the two sides of the road surface are at different heights, the distance measuring equipment cannot measure the inclination angles of the two sides of the road surface in time.

[0010] Preferably, a rotating shaft is fixedly mounted on the outer surface of one end of the auxiliary ruler and the scale, and one end of the auxiliary ruler and the scale are rotatably connected to the connecting frame through the rotating shaft. When both sides of the road surface are inclined, both ends of the scale will rotate along the connecting frame.
[0011] Preferably, the pointer assembly includes a turntable arranged on the outer surface of one side of the connecting frame, and a pointer is integrally installed on the outer surface of the turntable. A circle of scales is arranged on the outer surface of one side of the connecting frame at one end of the pointer. The turntable at one end is driven to rotate by a rotating shaft, and the inclination angle is adjusted by the pointer pointing to the scale.
