Description

Technical Field

[0001] This utility model relates to the field of slope measurement, and in particular to a slope measurement device for highway construction. Background Technology

[0002] In highway construction, slope measurement is a crucial step in ensuring construction quality and acceptance. Currently, pendulum gravity slope measuring instruments are widely used due to their portability, ease of operation, and fast measurement speed. However, existing equipment has a significant drawback: it cannot fix the pendulum after measurement. This makes it easy for construction workers to experience pendulum swaying due to external environmental interference (such as wind or physical contact) when reading data, affecting the accuracy of the readings and reducing work efficiency. Furthermore, because the pendulum is in a free state, the instrument cannot be picked up for close observation and reading, causing inconvenience in actual operation. Therefore, a highway construction slope measuring device is proposed to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a highway construction slope measuring device to solve the problem that the pendulum is in a free state after measurement, making it inconvenient to read the value.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a highway construction slope measuring device, including a base and a support frame set on the base. The top of the support frame is provided with a mounting frame, and a rotating shaft is rotatably provided in the mounting frame. A turntable is provided through the front end of the rotating shaft and the mounting frame. An angle plate is provided at the top of the mounting frame. A pointer matching the angle plate is provided at the top of the turntable. A pendulum is provided at the bottom and a level bubble is provided at the front. A locking part for fixing the rotating shaft is also provided on the mounting frame.

[0005] The locking part includes a telescopic hole on the mounting frame, two limiting grooves are symmetrically arranged on the telescopic hole, a telescopic rod is telescopically arranged in the telescopic hole, a limiting strip adapted to the limiting groove is arranged on the outside of the telescopic rod, an arc-shaped contact plate is arranged at the bottom end, and a telescopic spring is also fitted on the outside between the arc-shaped contact plate and the top wall of the mounting frame.

[0006] In the preferred embodiment, the top of the limiting strip is provided with an outwardly extending plate.

[0007] In the preferred embodiment, the telescopic rod and the arc-shaped contact plate are provided with a through hole, and the mounting frame is also provided with a reinforcing component that can pass through the bottom of the through hole.

[0008] In the preferred embodiment, the reinforcement component includes two bending frames symmetrically arranged at the top of the mounting frame, an internally threaded shaft between the two bending frames, a threaded rod threaded in the internally threaded shaft, and a handle at the bottom of the threaded rod.

[0009] In the preferred embodiment, rubber sheets are provided at the bottom ends of both the arc-shaped contact plate and the threaded rod.

[0010] In the preferred embodiment, the pendulum includes a connecting rod located at the bottom of the turntable, and a counterweight is provided at the bottom end of the connecting rod.

[0011] In the preferred embodiment, the front of the turntable is provided with a groove, and the horizontal bubble is placed in the groove.

[0012] In the preferred embodiment, adjustable support feet are provided at all four corners of the base.

[0013] In a preferred embodiment, the base has four receiving grooves located at its four corners on its top. The inner end of each receiving groove has a rotating hole. The support foot includes a crossbeam that is adapted to the receiving groove. The bottom of the inner end of the crossbeam has a rotating part that rotates with the rotating hole. The outer end extends to the outside of the receiving groove and is connected to a support foot.

[0014] This utility model provides a highway construction slope measuring device. By setting a rotating shaft in the mounting frame and setting a locking part on it, the rotating shaft can be fixed by the locking part, thereby fixing the turntable, pointer and pendulum. This prevents errors in the index caused by the external environment during observation. At the same time, by setting a horizontal bubble on the turntable, it is easy to determine the accuracy of the index when fixing the rotating shaft by observing the horizontal bubble, preventing the pointer from fixing with errors. In addition, the two-stage fixing structure can handle temporary fixing and long-term fixing respectively, effectively improving the operational convenience of temporary fixing.

Detailed Implementation

[0025] Example 1

[0026] like Figure 1-7 As shown, a highway construction slope measuring device includes a base 1 and a support frame 2 mounted on the base 1. The support frame 2 is vertically mounted on the base 1 in an inverted "T" shape. A mounting frame 3 is provided at the top of the support frame 2. A rotating shaft 4 is rotatably mounted in the mounting frame 3. Bearings are symmetrically arranged on opposite walls of the mounting frame 3. The rotating shaft 4 is rotatably mounted in the mounting frame 3 through the bearings. A turntable 6 is provided at the front end of the rotating shaft 4 through the mounting frame 3. An angle plate 5 is provided at the top of the mounting frame 3. The angle plate 5 is specifically located on the front side of the top of the mounting frame 3. A pointer 7 matching the angle plate 5 is provided at the top of the turntable 6. A pendulum 8 is provided at the bottom. A horizontal bubble 11 is provided on the front of the turntable 6. A locking part 9 for fixing the rotating shaft 4 is also provided on the mounting frame 3. The locking part 9 is located behind the angle plate 5. The pendulum 8 includes a connecting rod 801 provided at the bottom of the turntable 6. A counterweight 802 is provided at the bottom end of the connecting rod 801. A groove is provided on the front of the turntable 6, and the horizontal bubble 11 is located in the groove.

[0027] With this design, after placing the measuring device on the slope, the weight of the pendulum 8 causes the turntable 6 and the rotating shaft 4 to rotate, so that the pointer 7 points to the corresponding angle, thereby measuring the slope. Then, the rotating shaft 4 is locked by the locking part 9, which can prevent it from being affected by the external environment and affecting the accuracy of the reading. During this process, the accuracy of the measurement can be checked by the horizontal bubble 11 to prevent the pointer 7 from not pointing to the accurate position when the rotating shaft 4 is fixed.

[0028] In the preferred embodiment, the locking part 9 includes a telescopic hole 301 provided on the mounting frame 3. Two limiting grooves 302 are symmetrically provided on the telescopic hole 301. A telescopic rod 901 is telescopically provided in the telescopic hole 301. A limiting strip 902 adapted to the limiting groove 302 is provided on the outside of the telescopic rod 901. An arc-shaped contact plate 903 is provided at the bottom end. A telescopic spring 904 located between the arc-shaped contact plate 903 and the inner top wall of the mounting frame 3 is also fitted on the outside.

[0029] It should be noted that the arc-shaped contact plate 903 is adapted to the rotating shaft 4, and the inner diameter of the telescopic spring 904 is greater than the length between the telescopic hole 301 and the two limit bars 902.

[0030] This design allows the arc-shaped contact plate 903 to abut against the rotating shaft 4 through the tension of the telescopic spring 904, thus providing a limiting function. In addition, when locking is not required, the telescopic rod 901 can be lifted until the limiting strip 902 is pulled out of the limiting groove 302. Then, by rotating, the limiting strip 902 is placed on the top of the mounting frame 3 to prevent it from resetting. When needed, the limiting strip 902 can be rotated to be above the limiting groove 302. Furthermore, when the limiting strip 902 is aligned with the limiting groove 302, the arc-shaped contact plate 903 is in a state directly facing the rotating shaft 4, which facilitates the fit between the two.

[0031] In the preferred embodiment, the top of the limiting bar 902 is provided with an outwardly extending extension plate 905, which facilitates the extension and retraction of the telescopic rod 901 through the extension plate 905.

[0032] In the preferred embodiment, in order to further reinforce the rotating shaft 4, the telescopic rod 901 and the arc-shaped contact plate 903 are provided with a through hole 906, and the mounting frame 3 is also provided with a reinforcing component that can pass through the bottom of the through hole 906.

[0033] The reinforcement component includes two bending frames 907 symmetrically arranged on the top of the mounting frame 3. The bending frames 907 are inverted "L" shapes. An internal threaded shaft 908 is provided between the two bending frames 907. A threaded rod 909 is threaded in the internal threaded shaft 908. A handle 9010 is provided at the bottom of the threaded rod 909.

[0034] With this design, the threaded rod 909 can be rotated in the internal threaded shaft 908 by the handle 9010, thereby achieving the effect of passing through the bottom end of the through hole 906. When the bottom end of the threaded rod 909 passes through the through hole 906, it can abut against the rotating shaft 4, thereby further reinforcing the rotating shaft 4.

[0035] It should be noted that the bending frame 907 and the limiting groove 302 are arranged in a cross pattern to facilitate the operation of the extension plate 905 without affecting it, and the diameter of the through hole 906 is larger than the diameter of the threaded rod 909.

[0036] With the above structure, it can be fixed temporarily by the contact relationship between the arc-shaped contact plate 903 and the rotating shaft 4. When a large range of movement is required for observation, it can be reinforced by the threaded rod 909. This design can not only fix the reading, but also fix the pendulum 8 when the device is moved to prevent unnecessary shaking and impact.

[0037] In the preferred embodiment, both the bottom ends of the arc-shaped contact plate 903 and the threaded rod 906 are provided with rubber sheets. The rubber sheets can effectively enhance the friction of the contact surfaces, thereby improving the locking effect.

[0038] Example 2

[0039] Further explanation in conjunction with Example 1, such as Figure 1 and 8 As shown in the diagram, since the device needs to be placed on a slope, adjustable support feet 10 are provided at each of the four corners of the base 1 to ensure its stability on the slope.

[0040] The base 1 has a receiving groove 101 located at its four corners. The inner end of the receiving groove 101 is provided with a rotating hole 102. The support foot 10 includes a crossbeam 103 that is adapted to the receiving groove 101. The bottom of the inner end of the crossbeam 103 is provided with a rotating part 105 that rotates with the rotating hole 102. The outer end extends to the outside of the receiving groove 101 and is connected to a support foot 104. The crossbeam 103 and the support foot 104 form a sideways "L" shape.

[0041] With this design, the angle of use of the support leg 10 can be adjusted arbitrarily by rotating the rotating part 105 in the rotating hole 102, so that three-point support is formed when any end is at the bottom, thereby improving the stability of the device. When not in use, it can be rotated and stored in the receiving groove 101.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
