Description

A road and bridge engineering flatness detection device

Technical Field

The utility model relates to the technical field of measurement, in particular to a road and bridge engineering flatness detection device.

Background Art

The ruler method is often used to detect the flatness of the road in road and bridge projects. A measuring area is selected on the road surface. After the measuring area is cleaned, the ruler is placed flat on the road surface, and then the values of the ruler and the concave area of the road surface are measured, thereby realizing the detection of the road surface flatness.

After searching, the Chinese patent with the authorization announcement number CN218443704U discloses a road surface flatness tester, including a road surface flatness measuring instrument body, and a bubble level ruler is fixedly connected to the middle of the top of the road surface flatness measuring instrument body. The road surface flatness measuring instrument body is placed against the road surface, and the bottom of the road surface flatness measuring instrument body is ensured to be flat and in contact with the road surface, and the road surface flatness measuring instrument body is pressed firmly with force. Since a dense array of measuring head structures is arranged in the groove body of the road surface flatness measuring instrument body, if there is a depression at the road surface corresponding to the measuring head, the measuring head enters the depression under the action of the spring, and the indicator plate corresponding to the measuring head drops at this time, and the drop amount is displayed on the height scale. The height of the indicator plate here is obviously different from the height of the indicator plate at other flat positions, so as to achieve the purpose of obtaining the drop value by placing the level ruler, and the purpose of quick reading, and no need to insert the vernier feeler gauge, which is convenient to use.

The above patent makes the road surface flatness measuring instrument body fit to the road surface through the cooperation between the road surface flatness measuring instrument body and the measuring head. The measuring head is pressed against the road surface under the action of the spring force. When there is a depression in the road surface, the measuring head enters the depression under the action of the spring. The measuring head drives the corresponding indicator plate to descend, and the amount of descent is displayed through the height scale, thereby realizing the detection of the flatness of the road surface. However, when actually reading the height scale, since the height scale is close to the road surface, when making an accurate reading, the person needs to look straight at the indicator plate, and when looking straight at the indicator plate, the person needs to lie on the road surface to read the reading accurately. The reading is not convenient enough. Therefore, the present application provides a road and bridge engineering flatness detection device to meet the demand.

In the above scheme, the bracket is placed on the road surface through the setting of the marker pen, drawing board and roller, and the roller is moved to the right to roll to the right along the road surface. When encountering a concave area of the road surface, the roller moves downward to drive the marker pen to move downward. The marker pen draws a downward curve on the drawing board, and the value of the scale line corresponding to the bottom of the downward curve is read during the measurement process. There is no need for people to lie on the road surface during the reading process, so the reading is more convenient.

By setting the handle, the handle is inclined. When the square rod is moved through the sliding plate while holding the handle, the sliding plate located above is subjected to a force diagonally downward, so that the sliding plate slides on the top of the bracket and presses on the bracket, thereby preventing the bracket from moving when the roller moves along the ground, achieving stable placement of the bracket and ensuring stability during the measurement process.

Through the setting of the square sleeve, after the measurement of the flatness of the road surface is completed, the fastening bolts are loosened, and then the square plate is moved downward so that the handle on the back of the square plate fits against the top of the square sleeve. The drawing board can be stored through the square sleeve, which effectively prevents the drawing board from being damaged, and reduces the height of the entire device, thereby improving the portability of the entire device.
