Direct reading flat gauge

The invention belongs to the field of measurement technology for road surface flatness, in particular to a direct reading type flat gauge which can be accurately and conveniently used, so as to efficiently and accurately measure the smoothness of the road surface, and at the same time achieve the province. Time and effort.

According to the road surface and road construction, it is necessary to consider the smoothness of the road surface to ensure the safety and comfort of driving. For example, using the high and low flatness tester, inertial flatness tester, laser flatness tester and three-meter straight gauge to measure the road surface flatness. To ensure safe driving and comfort.

As the road is leveled or not, in addition to the feeling of comfort for passers-by, it is closely related to driving safety. In order to improve the smoothness of the road surface and provide a safe and safe road for the people, the project will promote the road plan from the Republic of China in 1997. After more than four years of joint efforts of all relevant units, it has achieved considerable results. The major roads in all counties and cities have improved significantly in terms of quality or flatness. In order to have a flat road, in addition to good construction techniques, the inspection and acceptance stage is indispensable for the smoothness of the inspection.

In the conventional three-meter ruler, the three-dimensional ruler is composed of a horizontal frame (10) and a vertical triangular measuring block (20). The horizontal frame (10) is provided with a beam (15) between the two stands (11), and the bottom edge of the beam (15) is constructed with the bottom surfaces of the two side stands (11). A fixed height is maintained between the virtual levels, and a measuring space (16) is formed for a vertical triangular measuring block (20) to measure. Thus, when the horizontal frame (10) is placed on the road surface by using the two side stands (11), the vertical triangular measuring block (20) can be used to insert the measuring space (16) under the horizontal frame (10), and the horizontal frame is (10) The beam (15) is aligned with the position of the inclined surface of the vertical triangular measuring block (20) to interpret its height; however, the existing three-meter ruler is not practical. First, the vertical triangular measuring block (20) The bottom surface is flat and has a certain area, which affects the accuracy of the measurement; furthermore, the staff needs to constantly bend and move the vertical triangular measuring block (20) and carefully interpret it, so the use It is extremely inconvenient, and the long-term use may even cause the operator to suffer from back pain, which cannot meet the actual use requirements, so that the flatness of the road surface cannot be effectively measured. Therefore, how to improve the aforementioned problems is the industry's duty. Question.

The inventor of the present invention has intensively discussed the problem of measurement inconvenience faced by the aforementioned triangular ruler, and actively seeks solutions through years of experience in R&D and manufacturing of related industries, and has been continuously researching and trialing. Finally, we successfully developed a direct-reading leveling gauge to solve the inconvenience and trouble caused by the inability to effectively measure.

Therefore, the present invention mainly provides a direct-reading leveling gauge that can be accurately measured, thereby enabling rapid and effective measurement, greatly improving the accuracy of the measurement, and reducing the misjudgment.

Moreover, the second aspect of the present invention is mainly to provide a direct-reading flat gauge that is easy to operate, which can be quickly measured, and does not need to bend and repeat operations, thereby improving measurement efficiency and convenience.

The present invention mainly implements the foregoing objects and effects through the following technical means; it is composed of a horizontal frame and a depth measuring module disposed on the horizontal frame; the horizontal frame is tied to the two vertical frames. a beam is disposed between the bottom edge of the beam and a fixed height between the virtual levels formed by the bottom surfaces of the two side frames; and the depth measuring module has a housing that can be disposed on the horizontal frame, the shell The upper arm of the seat is provided with a scale wheel, the peripheral surface of the scale wheel has a numerical scale, and the other scale wheel has a synchronously rotating gear, and the rack seat is provided with a rack that can mesh with the gear, the rack The bottom part has a probe portion for penetrating the horizontal frame beam, and the rack probe portion passes through a virtual horizontal line lower than the bottom surface of the vertical frame on both sides of the horizontal frame, and a reset elastic member is provided between the other shell seat and the rack gear for the tooth The probe portion can be kept out of shape.

Therefore, through the foregoing technical means, the direct reading type flat gauge of the present invention can utilize the rack of the depth measuring module on the horizontal frame to drive the scale wheel, and at the same time, the probe can be acted upon by the reset elastic member. The design that keeps in contact with the road surface can quickly and effectively measure and improve the accuracy of measurement, further reduce the phenomenon of misjudgment and misalignment, and eliminate the need to bend over and repeat operations to improve the measurement efficiency and Convenience, which can increase the added value of products and enhance their economic benefits.
