Description

Technical Field

[0001] This application relates to the field of roadbed slope measurement technology, specifically a measuring instrument for measuring the slope of a roadbed slope. Background Technology

[0002] Roadbed slopes refer to the lateral slopes of the roadbed in transportation engineering projects such as highways and railways. The design and construction of slopes have a significant impact on the stability, erosion resistance, and overall performance of the roadbed.

[0003] Roadbed slopes are typically divided into several distinct sections for ease of design and construction. Generally, roadbed slopes can be divided into the following segments:

[0004] Upper slope: This slope is usually located at the edge of the top of the roadbed, and the slope may be relatively gentle to ensure the safety and comfort of vehicles passing through;

[0005] Middle slope section: This is the main part of the slope, and its gradient is generally steeper. The specific slope design depends on soil properties, geological conditions, and environmental factors. The stability of the middle slope section is crucial to the safety of the entire slope.

[0006] Lower slope section: The lower slope section is usually close to the natural ground, and the slope may vary. The design should take into account the prevention of soil erosion and landslides.

[0007] During the handover and acceptance of roadbeds, it is necessary to test the slope of the roadbed side slope. The traditional testing method is to use a slope gauge. During the test, the slope gauge is placed on the slope and then manually adjusted so that the bubble in the middle of the slope gauge is in a horizontal state. Then the pointer reading is read and the slope is read from the reference table on the back of the slope gauge. This is the slope of the roadbed side slope.

[0008] Because the slope measuring tape is small in size and has a short contact length with the roadbed slope, the test results are inaccurate. In this case, a three-meter straightedge is used for testing. One end of the three-meter straightedge is placed on the slope, and then the slope measuring tape is placed on the three-meter straightedge for testing.

[0009] However, since roadbed slopes are usually divided into multiple parts, using traditional measurement methods requires staff to test the slopes at multiple angles in batches, which is not only time-consuming and labor-intensive, but also increases the workload of workers and affects measurement efficiency. Therefore, it is necessary to provide a measuring instrument for measuring the slope of roadbed slopes to solve the above problems.

[0010] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0011] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a measuring instrument for measuring the slope of roadbed slopes, which enables rapid testing of slopes at multiple angles by adjusting the length and angle of multiple sets of rulers, saving time and effort and improving measurement efficiency.

[0012] The technical solution adopted by this application to solve its technical problem is: a measuring instrument for measuring the slope of a roadbed side slope, comprising:

[0013] At least three sets of rulers, the rulers having a first ruler, a second ruler, and a third ruler;

[0014] A slope ruler, the bottom of which is equipped with a magnetic piece, which is attached to a ruler by means of the magnetic piece;

[0015] The rotating mechanism has two sets of mounting plates installed on the side of the second ruler near the third ruler. A rotating rod is installed between the two sets of mounting plates. The third ruler has an arc-shaped groove on the side near the second ruler. A movable sleeve is installed in the arc-shaped groove and is fitted onto the rotating rod. The corner of the third ruler with the arc-shaped groove is set as an arc angle.

[0016] Furthermore, each set of rulers is provided with a fixing mechanism at the connecting end. The fixing mechanism has a locking post fixedly installed on one side of the first ruler. A threaded hole is opened on one side of the second ruler, and a bolt is threaded into the threaded hole. A locking plate is provided between the bolt and the locking post. A sleeve hole is opened at one end of the locking plate, which can be fitted onto the bolt. A locking groove is opened at the other end of the locking plate, and the locking groove cooperates with the locking post.

[0017] Furthermore, a storage mechanism is provided on one side of the first ruler. The storage mechanism has a placement groove on the first ruler, and a sliding groove is provided on one side of the placement groove. A protective plate is slidably connected in the sliding groove.

[0018] Furthermore, the upper and lower ends of the placement slot are provided with locking holes, and the upper and lower ends of the protective plate are provided with telescopic components, which correspond to the locking holes.

[0019] Furthermore, a handle is fixedly installed on the outer side of the protective plate.

[0020] The beneficial effects of this application are as follows: The measuring instrument provided by this application for measuring the slope of a roadbed slope can adjust the angle of some rulers by rotating the mechanism until all rulers are attached to the multiple roadbed slopes to be measured. Then, the protective plate is opened to take out the slope rulers and attach them to the upper surface of the rulers in turn to detect the inclination of the rulers, thereby obtaining the slope of the roadbed slope. Therefore, by adjusting the length and angle of multiple sets of rulers, slopes at multiple angles can be tested quickly, thus saving time and effort, reducing the workload of workers, and improving measurement efficiency.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] like Figure 1 As shown, this application provides a measuring instrument for measuring the slope of a roadbed, including three sets of rulers, namely the first ruler 1, the second ruler 5, and the third ruler 6. The three sets of rulers have the same structure and shape and are all made of iron. A slope ruler 4 is provided on the first ruler 1. A magnet 41 is fixedly installed on the bottom of the slope ruler 4. The slope ruler 4 can be easily installed on any side of the three sets of rulers by magnetic attraction through the magnet 41.

[0037] like Figure 1 and Figure 4 As shown, a rotating mechanism 2 is provided between each set of rulers, connecting the three sets of rulers. For ease of understanding, the following explanation will focus on the rotating mechanism 2 between the second ruler 5 and the third ruler 6.

[0038] The rotating mechanism 2 has two sets of mounting plates 21 fixedly installed on the side of the second ruler 5 near the third ruler 6. A rotating rod 22 is fixedly installed between the two sets of mounting plates 21. At the same time, an arc-shaped groove 23 is opened on the side of the third ruler 6 near the second ruler 5. A movable sleeve 24 is fixedly installed in the arc-shaped groove 23. The movable sleeve 24 is sleeved on the rotating rod 22. Therefore, the third ruler 6 can rotate on the rotating rod 22 through the movable sleeve 24. Moreover, the corner of the end of the third ruler 6 with the arc-shaped groove 23 is set as an arc angle. Therefore, when the third ruler 6 rotates, it will not collide with the second ruler 5.

[0039] like Figures 2-3 As shown, in order to fix each set of rulers to each other, a fixing mechanism 3 is provided at the connecting end of each set of rulers. For ease of understanding, the following explanation will take the fixing mechanism 3 between the first ruler 1 and the second ruler 5 as an example. Specifically:

[0040] The fixing mechanism 3 has a locking post 31 fixedly installed on one side of the first ruler 1, and a threaded hole 32 opened on one side of the second ruler 5. A bolt 33 is threaded into the threaded hole 32. A locking plate 34 is provided between the bolt 33 and the locking post 31. One end of the locking plate 34 has a sleeve hole 35, which can be sleeved on the bolt 33. The other end of the locking plate 34 has a locking groove 36, which cooperates with the locking post 31. Therefore, loosening the bolt 33 allows the locking plate 34 to rotate on the bolt 33 through the sleeve hole 35 until the locking groove 36 is locked on the locking post 31. Then the bolt 33 is tightened to fix the locking plate 34. Thus, the first ruler 1 and the second ruler 5 are fixed by the locking plate 34.

[0041] like Figure 1 and Figures 4-5 As shown, in order to facilitate the temporary storage of the slope ruler 4, a storage mechanism 11 is provided on one side of the first ruler 1. The storage mechanism 11 has a placement groove 111 opened on the first ruler 1. A sliding groove 112 is opened on one side of the placement groove 111. A protective plate 113 is slidably connected in the sliding groove 112. A handle 114 is fixedly installed on the outer side of the protective plate 113. Therefore, the protective plate 113 can be pushed and slid in the sliding groove 112 by the handle 114 to cover or open the placement groove 111.

[0042] Meanwhile, locking holes 116 are provided at both the upper and lower ends of the placement groove 111, and telescopic members 115 are provided at both the upper and lower ends of the protective plate 113. The telescopic members 115 correspond to the locking holes 116. It can be understood that the outer end of the telescopic member 115 is arc-shaped, and an installation hole (not shown) is provided on the protective plate 113. The telescopic member 115 is slidably connected in the installation hole, and a spring is fixedly installed between the telescopic member 115 and the installation hole. Therefore, the telescopic member 115 can retract into the protective plate 113 when it is under pressure. When the telescopic member 115 reaches the locking hole 116, it will lock into the locking hole 116, thereby fixing the protective plate 113. Therefore, if the slope ruler 4 is not used or the three sets of rulers need to be moved, the slope ruler 4 can be temporarily stored in the placement groove 111 to prevent damage or loss.

[0043] In this application, the ruler can be set in multiple sets, and can be added according to the site conditions.

[0044] In summary, when measuring roadbed slopes, the length of the ruler is first adjusted according to the slope length, and the angle of some rulers can be adjusted by rotating mechanism 2 until all rulers are attached to the multiple roadbed slopes to be measured. Then, the protective plate 113 is opened to take out the slope gauge 4 and attach it to the upper surface of the ruler in turn to detect the inclination of the ruler, thereby obtaining the slope of the roadbed slope. Therefore, by adjusting the length and angle of multiple sets of rulers, slopes at multiple angles can be tested quickly, thus saving time and effort, reducing the workload of workers, and improving measurement efficiency.

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