Description

It requires at least two people to complete the work, resulting in low efficiency, high cost, and inconvenience for on-site construction. GPS surveying is simple to operate, but it can only be used in flat, open areas. In deep foundation pits and deep excavated road cuts, GPS signals are absent, leading to poor measurement accuracy.

[0023] 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 are within the scope of protection of the present application.

[0024] While total station surveying offers high accuracy, it is cumbersome to operate and requires control points near the construction site. It necessitates at least two people working together, resulting in low efficiency, high cost, and unfavorable conditions for on-site construction. GPS surveying is simple to operate, but it can only be used in flat, open areas. In deep foundation pits and deep excavations, GPS signals are unavailable, leading to poor measurement accuracy.

[0025] This application provides a slope measurement device that can solve the technical problems of low slope measurement efficiency and poor measurement accuracy in the prior art.

[0026] Figure 1 This is a schematic diagram of the slope measuring device provided in the embodiments of this application.

[0027] See Figure 1This application provides a slope measuring device, including: a reading component, which includes a protractor 1 and a pointer 2 disposed on the protractor 1, wherein the lower end of the pointer 2 is rotatably connected to the center of the protractor 1, and the lower end of the protractor 1 is provided with a support base; and a testing component, which includes a plurality of laser rangefinders disposed at intervals on the pointer 2 for measuring the distance between the pointer 2 and the slope to be measured, wherein the plurality of laser rangefinders are arranged along the length direction of the pointer 2, and the laser rangefinders are perpendicular to the pointer 2.

[0028] Specifically, the embodiments of this application include a first laser rangefinder 3 and a second laser rangefinder 4. Both the first laser rangefinder 3 and the second laser rangefinder 4 are vertically arranged on the pointer 2, and both the first laser rangefinder 3 and the second laser rangefinder 4 emit lasers in the direction of the slope. When the distances measured by the first laser rangefinder 3 and the second laser rangefinder 4 are equal, the degree corresponding to the scale of the protractor 1 pointed to by the pointer 2 is taken as the slope of the slope.

[0029] In this embodiment, the rotation of pointer 2 around the center of protractor 1 can drive multiple laser rangefinders to rotate. When the distances measured by the multiple laser rangefinders are equal, pointer 2 is parallel to the slope. The degree indicated by pointer 2 at this time is taken as the slope ratio. Through this measuring device, this embodiment can achieve rapid measurement of slope ratio. It is simple to operate, highly accurate, and avoids the cumbersome data calculations associated with total station measurements. The measurement results are simple and intuitive, and one person can quickly complete the measurement work, saving manpower, material resources, and time costs. This embodiment also includes a support base for leveling protractor 1, further improving the accuracy of the measurement results. The overall structure of the measuring device is simple and the manufacturing cost is low.

[0030] In this embodiment of the application, the support base includes a connecting rod 6 fixedly connected to the lower end of the protractor 1, and a top plate 9 and a bottom plate 11 arranged at vertical intervals. The upper end of the connecting rod 6 is connected to the lower end of the protractor 1, and the lower end of the connecting rod 6 is connected to the top surface of the top plate 9. A plurality of foot screws 10 are provided between the top plate 9 and the bottom plate 11. The upper end of the foot screws 10 is threadedly connected to the top plate 9. A level bubble meter 8 is provided on the top surface of the top plate 9.

[0031] Specifically, before measuring the slope, the protractor 1 needs to be leveled so that its bottom edge is parallel to the geoid. The slope measuring device is placed on the level ground at the foot of the slope. The leveling screws 10 are adjusted to keep the horizontal bubble on the top plate 9 horizontal. This embodiment includes at least three leveling screws 10. In practice, two leveling screws 10 can be adjusted first to move the bubble in the horizontal bubble meter 8 towards the center. According to the "left-hand thumb principle," the direction of bubble movement is the same as the direction of rotation of the left thumb. For example, if the bubble deviates to the left, the left-hand leveling screw 10 is rotated to the right; if the bubble deviates to the right, the right-hand leveling screw 10 is rotated to the left.

[0032] In this embodiment, a support base is used. On the one hand, the protractor 1 can be precisely adjusted to be parallel to the geoid by the use of the foot screw 10 and the level bubble meter 8, thereby ensuring that the measured slope ratio is more accurate. On the other hand, it can provide certain support for the test components, making the measurement process of the entire slope test device safer.

[0033] In this embodiment of the application, a tripod is also provided below the base plate 11. The tripod includes a mounting plate connected to the base plate 11 and three support legs rotatably connected to the bottom of the mounting plate.

[0034] Specifically, a tripod is set under the base plate 11, which allows the slope measuring device provided in this application embodiment to adapt to various terrain conditions and ensure the stability of the measurement process under different terrain conditions. The length of each support leg can be adjusted according to the flatness of the ground, and the level of the protractor 1 can be initially adjusted by the tripod.

[0035] In this embodiment, a fixing sleeve is fitted on the connecting rod 6, and the bottom end of the fixing sleeve is fixed to the top surface of the top plate 9. A threaded hole is provided on the fixing sleeve, and a connecting rod retainer 7 is provided in the threaded hole.

[0036] Specifically, the fixing sleeve allows adjustment of the position of the connecting rod 6 within the fixing sleeve, thereby enabling fine-tuning of the angle of the protractor 1. After adjustment to a suitable height, the connecting rod retainer 7 securely fixes the connecting rod 6 within the fixing sleeve, preventing the connecting rod 6 from loosening or shifting during measurement. In this embodiment, the connecting rod retainer 7 can be a locking screw.

[0037] In this embodiment, the pointer 2 includes: a rotating part located on the same straight line, the lower end of which is rotatably connected to the center of the protractor 1; multiple laser rangefinders are spaced apart on the rotating part and arranged along the length of the rotating part; and a pointing part, the lower end of which is fixedly connected to the top end of the rotating part.

[0038] By segmenting the rotating part and the pointing part, on the one hand, the pointer 2 can more accurately indicate the scale of the protractor 1, thereby improving the accuracy of slope ratio measurement; on the other hand, the rotating part provides more fixing space for multiple laser rangefinders, improving the stability of the overall slope ratio measurement device.

[0039] In this embodiment of the application, a plurality of limiting holes are provided through the rotating part, and a laser rangefinder is inserted into the limiting holes, with each limiting hole corresponding to a laser rangefinder.

[0040] Specifically, the design of the limiting hole fixes the position of the laser rangefinder on the rotating part, preventing it from shaking or shifting during measurement, thus enhancing the stability of the device. At the same time, the laser rangefinder is installed through the limiting hole, which is a simple and easy installation method, facilitating installation and disassembly, maintenance and replacement, and reducing the cost of use.

[0041] In the embodiments of this application, both the rotating part and the pointing part are cylindrical, and the cross-sectional diameter of the pointing part is smaller than that of the rotating part.

[0042] Specifically, the rotating part and the pointing part can be designed as a single integral structure. In some embodiments of this application, the pointing part can also be set as an arrow shape, so that the pointing part on the scale of the protractor 1 is more accurate and can more clearly indicate the specific degree on the scale of the protractor 1, thereby improving the accuracy and intuitiveness of the measurement.

[0043] In this embodiment of the application, a rotating shaft is provided at the center of the protractor 1, and the lower end of the pointer 2 is fixedly connected to the rotating shaft.

[0044] Specifically, the rotating shaft is equipped with a pointer retainer 5 for locking or unlocking the pointer 2. By rotating the pointer retainer 5, the pointer 2 rotates around the center of the protractor 1 until the distances measured by the first laser rangefinder 3 and the second laser rangefinder 4 fixed to the pointer 2 are equal. At this time, the pointer 2 can be locked by the pointer retainer 5, and the degree value pointed to by the pointer 2 at this time can be read. The read degree value is used as the slope of the ramp.

[0045] In this embodiment, the pointer retainer 5 is a locking screw.

[0046] Specifically, a handle is fixedly connected to the end of the pointer retainer 5 away from the rotation axis. The pointer retainer 5 can be turned by the handle, so that the operator can quickly lock or unlock the pointer 2 without complicated operation steps.

[0047] Figure 2 This is an application scenario diagram of the slope measurement device provided in the embodiments of this application.

[0048] See Figure 2The slope measuring device is placed on a flat surface below the slope to measure its slope ratio. During the measurement process, the operator first adjusts the leveling screw 10 to ensure the device is horizontal. Then, the pointer 2 is rotated so that the first laser rangefinder 3 and the second laser rangefinder 4 on the rotating part face the slope, and the first laser rangefinder 3 and the second laser rangefinder 4 are activated to take measurements. When the distances measured by the first laser rangefinder 3 and the second laser rangefinder 4 are equal, the pointer 2 is stopped, and the degree reading on the scale of the protractor 1 is read through the pointing part; this degree reading is the slope ratio of the slope.

[0049] In this embodiment, the rotation of pointer 2 around the center of protractor 1 can drive multiple laser rangefinders to rotate. When the distances measured by the multiple laser rangefinders are equal, pointer 2 is parallel to the slope. The degree indicated by pointer 2 at this time is taken as the slope ratio. Through this measuring device, this embodiment can achieve rapid measurement of slope ratio. It is simple to operate, highly accurate, and avoids the cumbersome data calculations associated with total station measurements. The measurement results are simple and intuitive, and one person can quickly complete the measurement work, saving manpower, material resources, and time costs. This embodiment also includes a support base for leveling protractor 1, further improving the accuracy of the measurement results. The overall structure of the measuring device is simple and the manufacturing cost is low.
