[0011] Compared with the prior art, the utility model has the beneficial effects as follows:

[0012] 1、The device is placed on the surface of the bridge, the movable column is pushed to drive the locking block to move, so that the rotation angle of the movable rod is flexibly adjusted, when the bubble level shows the horizontal state, the value of the angle ruler pointed by the pointer on the movable rod is the slope value, at this time, the movable column is loosened, the locking block is tightly combined with the angle ruler under the action of the tension spring, the movable rod and the pointer are accurately positioned, the operator can easily take the device to the position where the line of sight is level with the reading, the convenience of reading is greatly improved, the reading error caused by the inclined line of sight is effectively avoided, the measurement accuracy is significantly improved, the device has the advantages of convenient reading and convenient use.

[0013] 2. This utility model, through the design of an opening, a sliding opening, a movable frame, and positioning columns, addresses the issue of uneven bridge surfaces. When the bridge surface is uneven, the bottom of the positioning frame cannot effectively adhere to the surface. The operator can adjust the movable frame downwards, causing the positioning columns to move downwards as well. This allows the bottom of the positioning columns to penetrate the opening and extend below the positioning frame. The positioning columns are tapered, utilizing the principle that two points determine a straight line. By contacting the bottoms of the two positioning columns with the bridge surface and adjusting the positioning frame to be as level as possible with the bridge surface, the bridge slope can be measured. To avoid significant errors, the operator can take multiple measurements. The device utilizes the fundamental mathematical principle that "two points determine a straight line." When the bridge surface is uneven and the positioning frame cannot directly adhere well to the surface, contacting the bottoms of the two positioning columns with the bridge surface establishes a straight line between these two positioning points. The design of the positioning frame and other components, such as the movable rod, allows the bubble level on the movable rod to find the horizontal position based on this straight line determined by the positioning columns. When the bubble level displays a horizontal reading, it indicates that the movable rod is in a horizontal position. At this point, the pointer on the movable rod points to the value on the angle gauge, accurately reflecting the bridge's slope at that location. This measurement principle is scientific and reasonable. The positioning column adopts a conical design, which allows for better contact with the bridge surface, reducing measurement errors caused by insufficient contact area or unevenness. Simultaneously, the opening at the bottom of the inner wall of the positioning frame and the sliding opening on the front of the angle gauge, in conjunction with the movable frame and positioning column, allow the positioning column to be flexibly adjusted vertically according to the actual conditions of the bridge surface. Furthermore, the fixed block, threaded rod, and rotating handle facilitate precise height adjustment by the operator, ensuring that the positioning column accurately reaches the appropriate position for contact with the bridge surface. The entire structure is compact and reasonable, providing strong structural support for the feasibility of the measurement. To ensure the accuracy of the measurement results, the device also considers error control. Operators can reduce errors through multiple measurements, a simple and effective error control method, as bridge surface conditions can vary, and unevenness is common. This measurement method can adapt to different bridge surface conditions by adjusting the positioning column. It can effectively measure both slight and severe unevenness, greatly expanding the applicable scenarios of the device. Attached Figure Description
