Description

Technical Field

[0001] This application belongs to the field of road quality assessment technology, specifically relating to a rapid detection device for road surface bumps. Background Technology

[0002] Since road surface slab undulation is calculated based on 10m data points to determine the Road Surface Bounce Index (PBI) for the entire assessment unit, the severity of slab undulation at a single point significantly impacts the overall kilometer score. Furthermore, differences in the equipment used by different testing vehicles and variations in individual test trajectories lead to inconsistencies in test results between different testing units, making it difficult to reconcile conflicting findings. Therefore, a convenient and rapid device is needed to verify data from individual sections with severe slab undulation and accurately measure the maximum elevation difference (the difference between the maximum and minimum elevations of the 10m road longitudinal profile) within a 10m range.

[0003] For specific assessment methods, please refer to the description of road surface slab ... Utility Model Content

[0025] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0026] Example 1

[0027] refer to Figures 1-3 As shown, a rapid detection device for road surface bumps includes a detection ruler, which is used to measure the difference in road surface elevation within the detection range.

[0028] The measuring ruler consists of several ruler segments 1, and each ruler segment 1 also includes a leveling bubble 3, a leveling knob 4, and a distance sensor 5.

[0029] The ends of two connected ruler segments 1 are hinged together, so that all ruler segments 1 of the test ruler can be unfolded as a whole to form a straight ruler for jump detection. Alternatively, all ruler segments 1 can be flipped and folded to form a small-span storage state, which is convenient for transportation or carrying.

[0030] A leveling bubble 3 is provided above the middle of the ruler segment 1. The leveling bubble 3 is used to visually observe the horizontal state of the ruler segment 1. Leveling knobs 4 are provided at both ends of the ruler segment 1. The leveling knobs 4 are placed on the ground. By adjusting the support height of the ruler segment 1, the two ends of the ruler segment 1 are made to be at the same height, ensuring that the ruler segment 1 is horizontal during the test.

[0031] Several distance measuring sensors 5 are arranged at intervals along the length of the ruler segment 1. The distance measuring sensors 5 are used to specifically measure the distance between the sensor and the ground. Since all the distance measuring sensors 5 are located on the same horizontal plane, the maximum elevation difference can be obtained by measuring the distance value.

[0032] Both the ruler and ruler segment 1 are rectangular structures, which facilitates processing and manufacturing. Furthermore, the rectangular structure of ruler segment 1 also facilitates the fitting and docking of its end faces.

[0033] If the measuring ruler is 10m long, it is suitable for evaluation standards within a 10m range. The ruler segment 1 consists of five sections, each 2m long. When the five ruler segments 1 are unfolded, they form a 10m long measuring ruler. When the five ruler segments 1 are folded, they form a single 2m storage length.

[0034] The ruler segments 1 are hinged together by hinges 2, which realizes the specific hinged connection between the ruler segments 1. The hinges 2 have a simple structure, reliable hinge connection, and are easy to install and connect.

[0035] The hinges 2 at both ends of the ruler segment 1 are arranged diagonally to stagger the direction of the ruler segment 1 when it is flipped and folded, so as to avoid interference caused by flipping and folding to the same side.

[0036] The leveling knob 4 includes a knob, stud, and support plate in one piece. The upper end of the knob is welded to the stud, which is screwed onto the ruler section 1. The lower end of the stud is welded to the support plate. By rotating the knob, the threaded engagement between the stud and the ruler section 1 is achieved, thereby adjusting the height of the support plate and creating different support heights for the ruler section 1, ultimately achieving the leveling of the ruler section 1.

[0037] The leveling knob 4 is embedded within the ruler segment 1. Specifically, a groove is cut into the ruler segment 1 to minimize the protrusion of the leveling knob 4 from the top and bottom surfaces, thus facilitating the folding and storage of the ruler segment 1. Of course, during jump testing, the leveling knob 4 needs to be extended out of the groove for leveling support.

[0038] Twenty ranging sensors 5 are arranged on the ruler segment 1. The distance between two adjacent ranging sensors 5 is 0.1m, which is in line with the evaluation standard of 0.1m detection distance.

[0039] The ranging sensor 5 is a miniature laser ranging sensor. The ranging sensor 5 is electrically connected to the control unit. The control unit converts the detection data and transmits the final data to the receiving unit via a data cable or wireless module. The receiving unit collects and calculates the final data.

[0040] The distance sensor 5 is embedded in the ruler segment 1. By keeping the measuring base surface of the distance sensor 5 flush with the lower end surface of the ruler segment 1, the distance measured by the sensor is the distance between the lower end surface of the ruler and the ground, which is convenient for observation and verification, and also makes the whole thing more aesthetically pleasing.

[0041] The mating end face of the ruler segment 1 is provided with a mating magnetic block 6. When the test is unfolded, the two adjacent ruler segments 1 are mated and attracted to each other. The magnetic force enables the entire test ruler to maintain a straight state and ensure the accuracy of the test.

[0042] The working principle of this application is as follows: the ruler is set to be foldable for easy carrying. By rotating the fine adjustment knob, all the level bubbles are centered to determine that the ruler is completely horizontal. When the ruler is completely horizontal, the elevation from the ruler to the ground can be measured. The control unit controls the miniature laser rangefinder to start measuring the elevation and can connect with electronic devices to transmit measurement data. The maximum and minimum elevation values ​​are automatically identified and subtracted to obtain the maximum elevation difference of the road longitudinal section, thereby determining the degree of road bump.

[0043] The method of using this application is as follows: Open the ruler, rotate the fine adjustment knobs sequentially until all bubbles are horizontal, open the control unit, click the start button to start measuring the distance, click the transmit button to start transmitting data, and complete the measurement.

[0044] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
