Description

Technical Field

[0001] This utility model relates to the field of road marking measuring ruler technology, specifically a road marking measuring ruler with a quick positioning function. Background Technology

[0002] Road marking measuring rulers are tools specifically designed for measuring the geometric parameters of road markings (such as lane lines, zebra crossings, edge lines, etc.). They require high precision and need to be adapted to complex shapes such as linear and curved lines. Distance measuring vehicles are portable distance measuring tools that convert the distance of a rolling wheel into length. They are easy to operate, highly efficient, and suitable for rapid measurement of long distances (such as roads and sites). They are widely used in engineering surveying, land measurement, and other scenarios.

[0003] The existing technical solution still has the following problems when used:

[0004] Specifically, in the process of using a road marking measuring ruler in conjunction with a distance measuring vehicle, the distance measuring vehicle, as the core length reference tool, directly relies on the stable contact and uniform rolling speed between the roller and the road surface for measurement accuracy. However, the actual road environment often contains a large number of pollutants—when the roller rolls on asphalt or cement pavement, it inevitably crushes and adheres to gravel, sand, mud clods, and even impurities such as residual marking paint particles and glass shards from construction. Among these impurities, larger stones may embed themselves in the rubber texture or gaps on the roller surface, while sticky mud will adhere to the edge of the roller in a damp environment, forming irregular protrusions;

[0005] Such impurities can cause multi-dimensional interference in measurements: On the one hand, embedded impurities effectively increase the actual diameter of the roller, leading to a positive deviation in the cumulative length measurement; on the other hand, protruding impurities may cause the roller to jam during rolling, resulting in fluctuating rotation speeds and disrupting the uniform transmission relationship of the counting gears, causing the measured value to fluctuate greatly; if the impurities are slippery mud, they may also reduce the friction between the roller and the road surface, causing local slippage and resulting in the roller rotating less than the actual distance traveled, forming a negative deviation with a smaller measured value. These errors will directly affect subsequent work: for road marking construction and acceptance, they may lead to misjudgment; for maintenance work, they will interfere with the judgment of the wear and tear and breakage distance of the markings, causing the maintenance plan to be inaccurate.

[0006] Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0007] The purpose of this invention is to provide a road marking measuring ruler with a rapid positioning function to solve the problems mentioned in the background art.

The mating end of the cleaning block is connected to a plug-in block. The side rod is connected to a positioning plate on the side near the plug-in block. A locking bolt is connected through the surface of the positioning plate.

[0010] Preferably, the starting arrow is set perpendicular to the ground, and the side rod is set parallel to the ground.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a road marking measuring ruler with a quick positioning function, comprising: a roller 1 and a starting arrow 101 installed on one side of the roller 1, a wear-resistant rubber tire 2 connected to the surface of the roller 1, a side plate 3 connected to one side of the roller 1, a data measuring instrument 4 installed on the surface of the side plate 3, a support rod 5 connected to the surface of the side plate 3, a bracket 6 connected to the surface of the support rod 5, a receiving block 7 connected to the top of the support rod 5, a telescopic rod 8 connected to the top opening of the receiving block 7, a handle 9 connected to the top of the telescopic rod 8, and a control switch 10 installed on the bottom surface of the handle 9;

[0025] A side rod 11 is connected to the side of the roller 1 near the starting arrow 101. A cleaning block 12 is connected to the other end of the side rod 11. A plug block 13 is connected to the mating end of the cleaning block 12. A positioning plate 14 is connected to the side of the side rod 11 near the plug block 13. A locking bolt 15 is connected through the surface of the positioning plate 14.

[0026] The starting arrow 101 is set perpendicular to the ground, the side rod 11 is set parallel to the ground, and the inner wall of the cleaning block 12 is equipped with a steel brush. The cleaning block 12 is slidably fitted into the opening on the surface of the side rod 11 through the plug-in block 13. The locking bolt 15 passes through the positioning plate 14 and forms a threaded connection with the opening at one end of the plug-in block 13. The cleaning block 12 with the steel brush structure installed inside facilitates the treatment of impurities on the wear-resistant rubber tire 2, thereby improving the accuracy of the measurement.

[0027] A pressing plate 16 is connected to the inner wall of the open end of the receiving block 7. A linkage block 17 is connected to the bottom end of the pressing plate 16. A linkage spring 18 is connected to the inner wall of the linkage block 17. The other end of the linkage spring 18 is connected to the inner wall of the receiving block 7. A locking block 19 is connected to the inner wall of the linkage block 17. A locking groove 20 is opened on the surface of the telescopic rod 8 near the locking block 19. By pressing the pressing plate 16, it is convenient to drive the linkage block 17 to move in linkage. It is convenient to control the telescopic rod 8 to extend and retract inside the support rod 5. This is convenient for workers of different heights to use.

[0028] Working principle: When using a road marking measuring ruler with quick positioning function, firstly, the roller 1 is moved to the road marking. At this time, the starting point of the road marking is measured through the starting arrow 101, and the measurement data is recorded by the data measuring instrument 4. Simultaneously, the plug block 13 at one end of the cleaning block 12 is inserted into the opening at one end of the side rod 11. Then, the locking bolt 15 is threaded through the positioning plate 14 and connected to the opening at one end of the plug block 13. This facilitates quick positioning and docking of the cleaning block 12. Afterwards, when the roller 1 rotates for measurement, the steel brush on the inner wall of the cleaning block 12 adheres to the surface of the roller 1. Impurities are cleaned to ensure the accuracy of road marking size measurement data; in addition, by pressing the pressing plate 16 on the surface of the receiving block 7, the linkage block 17 is moved inside the receiving block 7, which in turn causes the linkage block 17 to squeeze the linkage spring 18, and causes the locking block 19 on the other side of the linkage block 17 to move synchronously. At this time, the telescopic rod 8 is extended and retracted inside the support rod 5 to adjust different heights. After releasing the pressing plate 16, the rebound force of the linkage spring 18 causes the locking block 19 to engage with the locking groove 20 on the surface of the telescopic rod 8, which is convenient for different workers to use.
