Description

Technical Field

[0001] This utility model relates to the field of slope measurement technology, specifically a high slope measurement device for roadbed excavation sections. Background Technology

[0002] In road construction, the stability of high slopes in the excavated sections of the roadbed is crucial to the safety and quality of the entire road. Accurately measuring parameters such as slope, displacement, and deformation of high slopes is key to ensuring safe construction, assessing slope stability, and ensuring the long-term stable operation of the road. When measuring high slopes in the excavated sections of the roadbed manually, surveyors mainly rely on simple tools such as measuring tapes to carry out on-site operations. After measurement, the slope needs to be calculated, which is relatively inefficient.

[0003] The patent document with publication number CN220644376U discloses a high slope measuring device for roadbed excavation sections. This high slope measuring device for roadbed excavation sections can effectively measure the high slopes of roadbed excavation sections. By rotating the measuring plate, the measuring plate is made to fit the slope for measurement. The centerline of the measurement can be accurately marked with angles, making it very convenient for staff to read the angles.

[0004] While the above-mentioned technical solutions can achieve the effect of conveniently measuring slope angles, their functions are relatively limited, only capable of single angle measurement operations. When it is necessary to measure the length of roadbeds or slopes, additional measuring tools are required, making the above-mentioned technical solutions less practical. Therefore, a high slope measuring device for roadbed excavation sections is designed to solve the above-mentioned technical problems. Utility Model Content

[0033] The present invention will now be further described with reference to the accompanying drawings.

[0034] like Figures 1 to 9 As shown, a high slope measuring device for roadbed excavation sections includes a housing 10, which is U-shaped. A rotating mounting plate 20 is rotatably connected inside the housing 10. A support assembly is provided between the rotating mounting plate 20 and the housing 10 to support the rotating mounting plate 20, ensuring an angle of 90° between them. A detachable mounting base 30 is provided at the end of the rotating mounting plate 20. An indicator disc 40 is connected to the top of the mounting base 30, and a fixed connection is made to the middle of one side of the indicator disc 40. A collar 41 is connected, and a take-up drum 42 is rotatably connected to the outer circumferential surface of the collar 41. A flexible ruler 43 is provided on the outer circumferential surface of the take-up drum 42. An internally threaded sleeve 44 is fixedly connected to the middle of the side of the indicator disk 40 away from the collar 41. An angle indicating component is provided between the internally threaded sleeve 44 and the indicator disk 40. The angle indicating component is used to indicate the angle of the slope. A connection limiting structure 50 is provided between the internally threaded sleeve 44 and the collar 41. The connection limiting structure 50 is used to limit the take-up drum 42 so that the take-up drum 42 always rotates on the outer circumferential surface of the collar 41.

[0035] By setting a flexible measuring tape 43 with graduations, the length of the roadbed or slope can be measured. The rewinding drum 42 makes it easy to retract the measuring tape 43 after the measurement is completed, making the operation of measuring the length of the roadbed or slope more convenient.

[0036] It should be noted that the maximum diameter of the take-up drum 42 is not less than the diameter of the indicator disc 40, so as to facilitate the rotation of the take-up drum 42 and the winding operation of the flexible measuring tape 43.

[0037] like Figure 1 , Figure 8 and Figure 9 As shown, the support assembly includes positioning and storage slots 21 on two symmetrical sides of the rotating mounting plate 20 and a threaded rod threadedly connected to the storage shell 10. A knob 11 is connected to the end of the threaded rod, allowing for easy rotation. A support plate 22 is slidably connected inside the positioning and storage slots 21. A support insertion hole 23 is provided on one side of the end of the support plate 22, and the threaded rod is inserted into the support insertion hole 23. The size of the threaded rod matches the size of the support insertion hole 23. A limit is provided between the support plate 22 and the rotating mounting plate 20. The limiting component includes a limiting groove 24 formed on one side of the rotating mounting plate 20 and a limiting slide rod 25 connected to the support plate 22. The limiting slide rod 25 is located inside the limiting groove 24 and is slidably connected to the limiting groove 24. The diameter of the limiting slide rod 25 is equal to the width of the limiting groove 24, which can prevent the limiting slide rod 25 from shaking inside the limiting groove 24, thereby ensuring the stability of the support plate 22, and thus ensuring that the included angle between the storage shell 10 and the rotating mounting plate 20 can be stably maintained at 90°.

[0038] In its normal, unused state, the rotating mounting plate 20 is located inside the housing 10, and the support plate 22 is located inside the positioning storage slot 21. This allows the rotating mounting plate 20 and the support plate 22 to be folded up, reducing the space occupied by them. Before angle measurement of the high slope of the roadbed excavation section, the rotating mounting plate 20 is rotated and moved out of the housing 10. Then, the support plate 22 is moved out of the positioning storage slot 21 and adjusted to a suitable position and angle. During the movement and rotation of the support plate 22, the limiting slide rod 25 moves accordingly. The limiting slide rod 25 and the limiting groove 24 can prevent the support plate 22 from separating from the positioning and storage groove 21, so that the threaded rod corresponds to the position of the support insertion hole 23. Then, the knob is rotated to insert the threaded rod 11 into the support insertion hole 23, which fixes the support plate 22. At this time, the limiting slide rod 25 and the limiting groove 24 can prevent the support plate 22 from continuing to rotate. At this time, the angle between the rotating mounting plate 20 and the storage shell 10 is stably maintained at 90°.

[0039] It should be noted that the length of the rotating mounting plate 20 is greater than the length of the storage shell 10, so that the mounting base 30 will not interfere with the storage shell 10 during the rotation of the rotating mounting plate 20, allowing the rotating mounting plate 20 to be smoothly retracted into the storage shell 10. In addition, the length of the support plate 22 is less than the length of the positioning storage groove 21, and the thickness of the support plate 22 is less than the depth of the positioning storage groove 21, so that the support plate 22 can be completely retracted into the positioning storage groove 21.

[0040] like Figure 1-5 The connecting limiting structure 50 includes a limiting rod 51 that is threadedly connected to the internal threaded sleeve 44. One end of the limiting rod 51 is connected to a limiting plate 52, and the outer peripheral surface of the end of the limiting rod 51 away from the limiting plate 52 is threadedly connected to a limiting stop plate 53.

[0041] When installing the take-up drum 42, first, the take-up drum 42 is fitted onto the outer circumference of the collar 41. Then, the limiting rod 51 is threadedly connected to the internal threaded sleeve 44, and the limiting plate 52 is fitted against the end of the internal threaded sleeve 44. At this time, the limiting rod 51 passes through the inside of the collar 41 and is exposed on the outside of the collar 41. Then, the limiting stop plate 53 is threadedly connected to the limiting rod 51, and the limiting stop plate 53 is fitted against the end of the collar 41, thereby limiting the take-up drum 42. This ensures that the take-up drum 42 rotates smoothly while preventing the take-up drum 42 from separating from the collar 41, and makes the operation of installing the take-up drum 42 relatively simple. Similarly, it makes the operation of disassembling the take-up drum 42 relatively simple. When the flexible ruler 43 is damaged, it is easy to remove the take-up drum 42 and replace it.

[0042] It should be noted that the outer diameter of the limiting plate 53 is larger than the outer diameter of the collar 41, and the outer diameter of the limiting plate 53 is the same as the outer diameter of the indicator plate 40. This ensures the overall aesthetics while facilitating the rotation of the winding drum 42. Furthermore, a through hole is provided in the middle of one side of the indicator plate 40. The diameter of the through hole and the inner diameter of the collar 41 are both larger than the maximum diameter of the limiting rod 51, allowing the limiting rod 51 to pass smoothly through the through hole and the inside of the collar 41.

[0043] like Figure 1-4 and Figure 6 The angle indicating component includes a rotating sleeve 45 rotatably connected to the outer peripheral surface of the internal threaded sleeve 44 and an angle indicating mark 46 disposed on one side of the indicator disk 40. A pointer 47 and a connecting rod 48 are fixedly connected to the outer peripheral surface of the rotating sleeve 45. A counterweight 49 is fixedly connected to the bottom end of the connecting rod 48. The pointer 47 and the connecting rod 48 are symmetrically distributed on the outer peripheral surface of the rotating sleeve 45.

[0044] When measuring the angle of a slope, the housing 10 is placed in contact with the slope surface. Under the weight of the counterweight 49 and connecting rod 48, the rotating sleeve 45 rotates. As the rotating sleeve 45 rotates, the pointer 47 rotates accordingly. After the counterweight 49 reaches a stable position, it will be vertical. The angle of the slope can then be determined by observing the pointer 47 and the corresponding angle indicator 46. This simplifies the process of measuring the slope angle. A schematic diagram of slope measurement is shown below. Figure 2 As shown.

[0045] Before installing the take-up drum 42 and connecting the limiting rod 51 to the internal threaded sleeve 44, the rotating sleeve 45 can be fitted onto the outer circumferential surface of the internal threaded sleeve 44. After the limiting plate 53 is threadedly connected to the limiting rod 51 and the end of the limiting plate 53 is in contact with the end of the collar 41, the limiting plate 52 is in contact with the end of the internal threaded sleeve 44. At this time, the rotating sleeve 45 is limited so that the rotating sleeve 45 will not separate from the internal threaded sleeve 44, thus installing the angle indicating component. This makes the operation of installing the angle indicating component relatively simple. Similarly, when the pointer 47 is damaged, it is easy to remove the angle indicating component and replace it.

[0046] like Figure 1-4 , Figure 6 and Figure 7 As shown, the inner walls of both positioning and storage slots 21 are fitted with positioning plates 31 connected to the mounting base 30. A mounting bracket 32 ​​is fixedly connected to one side of one positioning plate 31. A fixing component is provided between the mounting bracket 32 ​​and the rotating mounting plate 20. The fixing component is used to fix the positioning plate 31. The fixing component includes a pin 33 that is slidably connected to the mounting bracket 32 ​​and a fixing hole 26 opened in the inner wall of the positioning and storage slot 21. The pin 33 passes through the positioning plate 31 and is slidably connected to the positioning plate 31. The diameter of the pin 33 is adapted to the diameter of the fixing hole 26. A movable block 34 is threadedly connected to the outer peripheral surface of the pin 33. A fixing spring 35 is sleeved on the outer peripheral surface of the pin 33. One end of the fixing spring 35 is in contact with the mounting bracket 32, and the other end of the fixing spring 35 is in contact with the movable block 34.

[0047] When connecting the mounting base 30 and the rotating mounting plate 20, first pull the pin 33 to move it away from the positioning plate 31 and separate the pin 33 from the positioning plate 31. During this process, the movable block 34 will move and squeeze the fixing spring 35. Then, the positioning plate 31 is inserted into the positioning and receiving groove 21, and the mounting base 30 is attached to the top side of the rotating mounting plate 20. At this time, the pin 33 is aligned with the fixed insertion hole 26. Then, the pin 33 can be slowly released. Under the reaction force of the fixing spring 35, the pin 33 is inserted into the fixed insertion hole 26, thus completing the operation of connecting the mounting base 30 and the rotating mounting plate 20. Similarly, it is easy to remove the mounting base 30, thereby reducing the overall size of the device and facilitating subsequent transportation and movement.

[0048] Because the movable block 34 and the pin 33 are connected by a thread, the operation of connecting the movable block 34 and the pin 33 is relatively simple. Similarly, it is easy to separate the pin 33 and the movable block 34. Thus, when the elasticity of the fixing spring 35 decreases, it is easy to replace the fixing spring 35. When replacing the fixing spring 35, keep the movable block 34 from rotating and rotate the pin 33 to separate the pin 33 from the movable block 34. At this time, the damaged fixing spring 35 can be removed and the new fixing spring 35 can be sleeved on the end of the pin 33. Then, the pin 33 can be reconnected to the movable block 34.

[0049] It should be noted that the cross-sectional shape of the pin 33 is L-shaped. The L-shaped pin 33 makes it easy for the operator to hold its end and move the pin 33. In normal state, one side of the movable block 34 is in contact with the positioning plate 31 to prevent the pin 33 from moving after it is inserted into the fixed socket 26.
