Description

Technical Field

[0001] This utility model is a slope inclination measuring device for civil engineering and rock slopes, belonging to the field of slope inclination measuring devices. Background Technology

[0002] In civil and geotechnical engineering, accurate measurement of slope inclination angle is a crucial step in ensuring project safety and design rationality. The data directly impacts slope stability assessment, support scheme design, and construction risk management. Currently, a number of existing inclination measurement devices with similar structures and principles to those in this design exist on the market. These typically include core components such as a housing, rotating cylinder, level, dial, and gear-driven adjustment mechanism, and can meet basic slope inclination angle measurement needs.

[0003] However, existing devices of this type are only equipped with one adjustment knob, which drives a rotating cylinder (and a level) through a single gear set for angle adjustment. This design has the problem of "difficulty in balancing adjustment efficiency and accuracy": if the gear set transmission ratio is designed for "rapid adjustment" (the knob rotation angle corresponds to a large angle change of the rotating cylinder), it is difficult to accurately calibrate when the cylinder is close to horizontal, and "over-adjustment" is likely to occur; if the transmission ratio is designed for "fine adjustment" (the knob rotation angle corresponds to a small angle change of the rotating cylinder), then when adjusting the angle over a wide range (such as from the initial tilt to near horizontal), too many turns of the knob are required, making the operation cumbersome. This will significantly reduce work efficiency, especially in field slope measurement (complex environment, limited operation time). Therefore, it is necessary to design a slope inclination measurement device for civil engineering and rock engineering. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for measuring the inclination angle of civil engineering and rock slopes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the inclination angle of a civil engineering slope, comprising:

[0006] The shell has an adjustment compartment inside and a notch in the upper right corner;

[0007] A rotating cylinder is rotatably connected inside the regulating chamber;

[0008] A cylindrical level is fixed inside the center of a rotating cylinder;

[0009] A dial is located on the surface of the housing at one end of the adjustment chamber, with its axis coinciding with the central axis of the rotating cylinder;

[0010] The fine-tuning knob and the coarse-tuning knob are located in the notch, and the fine-tuning knob and the coarse-tuning knob are the same in shape and size;

[0011] A gear transmission assembly is installed inside the adjustment chamber, and both the fine adjustment knob and the coarse adjustment knob are connected to the rotating cylinder via the gear transmission assembly.

[0012] The base is inserted into the bottom of the housing.

[0013] Furthermore, a hand grip groove is provided on one side of the housing, and a handle is inclined above the hand grip groove. Both sides of the handle are rounded, and a rubber pad is adhered to the surface of the handle.

[0014] Furthermore, an installation groove is provided at the center of the regulating chamber, and the outer diameter of the rotating cylinder matches the inner diameter of the installation groove, and the axial length of the rotating cylinder is consistent with the axial length of the installation groove.

[0015] Furthermore, both ends of the rotating cylinder are provided with outwardly protruding anti-detachment edges, and the outer diameter of the anti-detachment edges is larger than the inner diameter of the mounting groove. A pointer is fixed to the top of the anti-detachment edge near the end of the dial.

[0016] Furthermore, the base includes a mounting seat, rollers, and inserts, and the bottom of the base has a slot with a longitudinal section in the shape of a "T". The inserts are adapted to the slots. The bottom of the inserts is fixed with a mounting seat, and the longitudinal section of the mounting seat is "U". Multiple rollers are rotatably connected at equal intervals inside the mounting seat, and the bottom of the rollers is lower than the bottom surface of the mounting seat.

[0017] Furthermore, both the fine adjustment knob and the coarse adjustment knob consist of a main gear and two end plates, with the main gear clamped between the two end plates. The outer diameter of the end plates is larger than the outer diameter of the main gear. The inner sidewall of the notch is provided with a protruding limiting ridge along the radial direction of the end plate, and multiple limiting grooves arranged in a ring array are provided at one end of the end plate near the inner wall of the notch. The limiting grooves are adapted to the limiting ridges.

[0018] Furthermore, the gear transmission assembly includes a first transmission gear, a second transmission gear, a large gear disc, a third transmission gear, a fourth transmission gear, and a small gear disc. The first transmission gear meshes with the main gear of the fine adjustment knob, and the second transmission gear meshes with the first transmission gear. The second transmission gear meshes with the large gear disc, which is fixedly connected to the rotating cylinder. The third transmission gear meshes with the main gear of the coarse adjustment knob, and the fourth transmission gear meshes with the third transmission gear. The fourth transmission gear meshes with the small gear disc, which is fixedly connected to the rotating cylinder. Both the large gear disc and the small gear disc coincide with the central axis of the rotating cylinder.

[0019] Furthermore, both sides of the inside of the rotating cylinder are provided with inserts, and both sides of the cylindrical level are inserted into the inserts. The cylindrical level is perpendicular to the straight line where the pointer is located, and both sides of the outer surface of the cylindrical level are provided with positioning lines at equal intervals.

[0020] The beneficial effects of this utility model are:

[0021] 1. The device is equipped with coarse and fine adjustment knobs, which achieve different levels of precision through different gear transmission sets. The coarse adjustment knob, with the help of a gear set composed of a small gear plate, can quickly adjust the angle of the rotating cylinder over a wide range, which is suitable for rapid calibration in the initial stage. The fine adjustment knob, with the help of a gear set composed of a large gear plate, can make small-range fine adjustments to ensure the accuracy of angle calibration. This combination of "coarse adjustment + fine adjustment" mode, compared with the single adjustment method of traditional equipment, can quickly reduce the angle deviation and achieve precise calibration in a small range, which greatly improves the measurement efficiency and accuracy.

[0022] 2. Traditional equipment is prone to unevenness at the bottom due to wear and tear after long-term use, which can lead to instability, hidden tilt, and reading errors. The detachable base of this application can be easily removed and replaced by inserting a strip into the slot of the housing. When the bottom wears and affects the flatness, only the new base needs to be replaced, without replacing the main body of the equipment. This avoids measurement errors caused by bottom wear and also reduces maintenance costs. The base is equipped with multiple rollers, which allows the equipment to move smoothly on the slope surface and facilitates quick adjustment of the device position. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] Please see Figures 1 to 6 This utility model provides a technical solution: a device for measuring the inclination angle of a civil engineering slope, including a shell 1, an adjustment chamber 101 inside, and a notch 104 in the upper right corner;

[0042] Rotating cylinder 2 is rotatably connected to regulating chamber 101;

[0043] The cylindrical level 9 is fixed inside the center of the rotating cylinder 2;

[0044] The dial 5 is located on the surface of the housing 1 at one end of the adjustment chamber 101, and its axis coincides with the central axis of the rotating cylinder 2;

[0045] Fine adjustment knob 6 and coarse adjustment knob 7 are located in the notch 104, and fine adjustment knob 6 and coarse adjustment knob 7 have the same shape and size;

[0046] The gear transmission assembly 8 is located inside the adjustment chamber 101. The fine adjustment knob 6 and the coarse adjustment knob 7 are both connected to the rotating cylinder 2 via the gear transmission assembly 8.

[0047] Base 3 is inserted into the bottom of housing 1;

[0048] Please see Figure 1 A hand grip groove 105 is provided on one side of the housing 1, and a handle 4 is inclined above the hand grip groove 105. Both sides of the handle 4 are rounded, and a rubber pad is adhered to the surface of the handle 4. The tilt angle of the handle 4 is adapted to the human hand's force exertion habits. The rubber pad increases the friction between the hand and the handle 4, which can effectively prevent slippage when the hand is sweaty or the device vibrates slightly. At the same time, the elasticity of the rubber pad can cushion the pressure when the hand is gripping, further enhancing the operating comfort.

[0049] Please see Figure 2 and Figure 3 An installation groove 103 is provided at the center of the adjustment chamber 101, and the outer diameter of the rotating cylinder 2 matches the inner diameter of the installation groove 103. The axial length of the rotating cylinder 2 is consistent with the axial length of the installation groove 103. The precise matching of the dimensions of the rotating cylinder 2 and the installation groove 103 avoids radial swaying or left-right displacement of the rotating cylinder 2 when rotating or stationary due to excessive gap. This ensures that the rotating cylinder 2 always rotates stably around its own central axis, providing a solid mechanical reference for angle adjustment and reading. On the other hand, the consistency of their axial lengths prevents the rotating cylinder 2 from axially moving or shifting back and forth within the installation groove 103. This ensures that the relative position of the pointer 202 at one end of the rotating cylinder 2 and the scale 5 remains stable, avoiding reading deviations caused by axial displacement, and further improving the accuracy and reliability of the measurement.

[0050] Please see Figure 4 Both ends of the rotating cylinder 2 are provided with outwardly protruding anti-detachment edges 201, and the outer diameter of the anti-detachment edges 201 is larger than the inner diameter of the mounting groove 103. A pointer 202 is fixed on the top of the anti-detachment edges 201 near the end of the dial 5. Because the outer diameter of the anti-detachment edges 201 is larger than the inner diameter of the mounting groove 103, it can effectively limit the rotating cylinder 2 from the axial direction and prevent the rotating cylinder 2 from falling out of the mounting groove 103.

[0051] Please see Figure 1 , Figure 2 and Figure 5 The base 3 includes a mounting base 301, a roller 302, and an insert 303. The bottom of the base 3 has a slot 102 with a longitudinal section of "T". The insert 303 is adapted to the slot 102. The bottom of the insert 303 is fixed with the mounting base 301. The longitudinal section of the mounting base 301 is "U". Multiple rollers 302 are rotatably connected at equal intervals inside the mounting base 301. The bottom of the rollers 302 is lower than the bottom surface of the mounting base 301. This "T" shaped insertion structure not only realizes the quick assembly and disassembly of the base 3 and the housing 1, but also effectively limits the base 3 from the lateral and longitudinal directions, preventing the base 3 from sliding or falling off relative to the housing 1 during use, and ensuring the stability of the connection between the two.

[0052] The mounting base 301 has a "U"-shaped longitudinal section, which provides a stable spatial frame for the installation of the internal rollers 302. Multiple rollers 302 are rotatably connected to the inside of the mounting base 301 at equal intervals, and the bottom of the rollers 302 is lower than the bottom surface of the mounting base 301. This allows the device to move on the slope surface by rolling the rollers 302 instead of sliding directly, which greatly reduces the frictional resistance between the base 3 and the slope surface. This not only makes it easier for operators to adjust the position of the device, but also reduces the wear rate of the base 3.

[0053] Please see Figure 3 and Figure 4 Both the fine adjustment knob 6 and the coarse adjustment knob 7 consist of a main gear 601 and two end plates 602. The main gear 601 is clamped between the two end plates 602, and the outer diameter of the end plates 602 is larger than the outer diameter of the main gear 601. The inner wall of the notch 104 has a protruding limiting ridge 1041 radially arranged along the end plate 602. Multiple limiting grooves 6021 arranged in a ring array are provided at one end of the end plate 602 near the inner wall of the notch 104. The limiting grooves 6021 are adapted to the limiting ridges 1041. The limiting ridges 1041 on the inner wall of the notch 104 and the end plate 602... The ring-shaped array of limiting grooves 6021 on the end plate 602 are matched, which further improves the adjustment reliability of the knob: when the knob is rotated, the limiting ridge 1041 will sequentially engage with different limiting grooves 6021 as the end plate 602 rotates, forming a clear "gear feel", allowing the operator to intuitively perceive the adjustment range and avoid over- or under-adjustment; at the same time, the engaging action of the limiting ridge 1041 and the limiting groove 6021 can provide a positioning effect when the knob stops rotating, effectively preventing the knob from rotating accidentally due to vibration or accidental touch, and ensuring the stability of the adjusted angle position.

[0054] Please see Figure 4The gear transmission assembly 8 includes a first transmission gear 801, a second transmission gear 802, a large gear 803, a third transmission gear 804, a fourth transmission gear 805, and a small gear 806. The first transmission gear 801 meshes with the main gear 601 of the fine-tuning knob 6, and the second transmission gear 802 meshes with the first transmission gear 801 and the large gear 803, which is fixedly connected to the rotating cylinder 2. The third transmission gear 804 meshes with the main gear 601 of the coarse-tuning knob 7, and the fourth transmission gear 805 meshes with the third transmission gear 804 and the small gear 806, which is fixedly connected to the rotating cylinder 2. The large gear 803... Both the small gear 806 and the small gear 803 are aligned with the central axis of the rotating cylinder 2. The main gear 601 of the fine adjustment knob 6 meshes with the first transmission gear 801, the second transmission gear 802, and the large gear 803 in sequence. Because the large gear 803 has many teeth and a large diameter, when the fine adjustment knob 6 is rotated at a large angle, the rotating cylinder 2 only produces a small angle change, thus achieving fine angle adjustment and meeting the requirements of high-precision measurement. The main gear 601 of the coarse adjustment knob 7 meshes with the small gear 806 through the third transmission gear 804 and the fourth transmission gear 805. The small gear 806 has few teeth and a small diameter, which allows the coarse adjustment knob 7 to rotate at a small angle to drive the rotating cylinder 2 to produce a large angle change, making it easy to quickly adjust the rotating cylinder 2 to a position close to the target angle and improving operating efficiency.

[0055] Please see Figure 6 Both sides of the rotating cylinder 2 are provided with insert sleeves 203, and both sides of the cylindrical level 9 are inserted into the insert sleeves 203. The cylindrical level 9 is perpendicular to the straight line where the pointer 202 is located, and both sides of the outer surface of the cylindrical level 9 are provided with positioning lines 901 at equal intervals. The positioning lines 901 at equal intervals on both sides of the outer surface of the cylindrical level 9 provide a clear visual reference for judging the level state. The operator can quickly and accurately judge whether the level is in a level state by observing the relative position of the positioning lines 901 and the bubble inside the level.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
