Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically a slope measuring device for construction engineering supervision. Background Technology

[0002] In building engineering, road construction, and various fields that require precise measurement of ground slope, using slope measuring instruments is an important task.

[0003] Patent application number 201720272871.8 discloses a slope device, including a base, a leveling rod, and an angle ruler. The leveling rod has a counterweight and a pointer. Utilizing the principle of a roly-poly toy, the leveling rod will always stop horizontally regardless of the slope on which the base is placed, eliminating the need for manual correction. The measurement speed is fast, and the slope value can be clearly read from the angle ruler next to it without calculation, and the value is relatively accurate.

[0004] However, the aforementioned inclinometer cannot be fixed to a leveling pole. When the surveyor's viewing angle and the pointer are not coplanar, it is highly susceptible to parallax effects, causing deviations between the read angle value and the actual slope value. This affects the accuracy of the measurement results and makes it difficult to meet the requirements of high-precision engineering scenarios. If the surveyor has to lie flat on the ground to take the reading, it is not only inconvenient but also poses a risk of injury in some obstacle-prone areas.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a slope measuring device for construction engineering supervision. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slope measuring device for construction engineering supervision, so as to solve the problems mentioned in the background technology.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a slope measuring device for construction engineering supervision, including a base and an indicator dial. A pair of brackets are fixedly connected to the base, and a rotating rod is rotatably connected to the pair of brackets. A counterweight and a constant level rod are fixedly connected to the rotating rod, and a pointer matching the indicator dial is fixedly connected to the constant level rod. A first through hole is opened on the bracket, and a sliding rod is slidably connected to the first through hole on the pair of brackets. A fixed plate is fixedly connected to one end of the sliding rod, and a magnet is embedded in the fixed plate. The rotating rod passes through the bracket, and a first iron block matching the magnet is fixedly connected to the end of the rotating rod near the fixed plate. A device for preventing the sliding rod from rotating is provided on the sliding rod.

[0008] In one or more embodiments of the present invention, the device for preventing the sliding rod from rotating includes a limiting block, the limiting block being integrally formed on the sliding rod, and a limiting groove matching the limiting block being formed on the wall of the first through hole, the limiting block being slidably connected in the limiting groove.

[0009] In one or more embodiments of this utility model, the bracket is fitted with a bearing, and the rotating rod is fixedly connected to the inner rotating ring of a pair of bearings.

[0010] In one or more embodiments of this utility model, a connecting plate is fixedly connected to the indicator plate, and one end of the connecting plate away from the indicator plate is fixedly connected to a fixed plate, and the lower end surface of the indicator plate is higher than the upper end surface of the base.

[0011] In one or more embodiments of this utility model, the distance between the indicator dial and the pointer is greater than the distance between the magnet and the first iron block.

[0012] In one or more embodiments of this utility model, the sliding rod is a polytetrafluoroethylene rod.

[0013] In one or more embodiments of this utility model, a protective shell is fixedly connected to the base, a transparent wall is embedded in the protective shell, and a second iron block that matches the magnet block is fixedly connected to the protective shell.

[0014] In one or more embodiments of this utility model, the magnet block penetrates through the fixing plate.

[0015] In one or more embodiments of this utility model, a second through hole matching the sliding rod is provided on the transparent wall, and the end of the sliding rod away from the magnet block passes through the second through hole.

[0016] In one or more embodiments of this utility model, a second handle is fixedly connected to the end of the sliding rod away from the magnet block, and a first handle is fixedly connected to the protective shell.

[0017] The beneficial effects of this utility model are as follows: by locking the constant leveling rod, the limitation of traditional slope measuring instruments requiring fixed placement for reading is broken. The surveyor can hold the slope measuring instrument for construction engineering supervision by hand and adjust the viewing angle to ensure that the observation position is coplanar with the pointer, thus eliminating the hidden danger of reading deviation caused by viewing angle difference, ensuring the accuracy of measurement data, providing stable and reliable tool support for high-precision engineering measurement, and truly meeting the high requirements of engineering supervision work for measurement accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2As shown, a slope measuring device for construction engineering supervision according to one embodiment of this utility model includes a base 1 and an indicator dial 2. The lower end surface of the base 1 is horizontal. A pair of brackets 11 are welded to the upper end surface of the base 1. A rotating rod 12 is rotatably connected to the pair of brackets 11. A counterweight 121 and a leveling rod 13 are welded to the rotating rod 12. A pointer 131 matching the indicator dial 2 is welded to the leveling rod 13. In use, the leveling rod 13 can always remain horizontal under the action of gravity. The slope of the ground can be obtained by the value on the indicator dial 2 corresponding to the pointer 131. The above are all prior art and will not be described in detail.

[0023] like Figures 1 to 4 As shown, in order to lock the constant leveling rod 13, a first through hole 1101 is provided on the bracket 11. A sliding rod 4 is slidably connected in the first through hole 1101 on the bracket 11. A fixing plate 41 is integrally formed at one end of the sliding rod 4. A magnet 42 is embedded in the fixing plate 41. A rotating rod 12 passes through the bracket 11. A first iron block 122 matching the magnet 42 is welded to the end of the rotating rod 12 near the fixing plate 41. A limiting block 43 for preventing the sliding rod 4 from rotating is integrally formed on the sliding rod 4. Specifically, a limiting groove 1102 matching the limiting block 43 is provided on the hole wall of the first through hole 1101. The limiting block 43 is slidably connected in the limiting groove 1102. When the base 1 is placed on the ground to be tested, after the constant leveling rod 13 is stable, the sliding rod 4 is pulled. The magnet 42 gradually approaches the first iron block 122, so that it can be magnetically attracted to the first iron block 122, thereby locking the rotating rod 12. By picking up base 1 and placing it on the same plane as the inspector's line of sight, the reading can be taken, thus avoiding reading errors caused by differences in viewing angle.

[0024] In addition, during the transportation of the slope measuring device for construction engineering supervision, the locking of the rotating rod 12 by the magnet block 42 can prevent the constant level rod 13 from rotating and prevent the pointer 131 on the constant level rod 13 from colliding with the base 1, causing bending and deformation, which would affect its use.

[0025] Preferably, the sliding rod 4 is a polytetrafluoroethylene rod. Polytetrafluoroethylene has an extremely low coefficient of friction, which can reduce the friction between the sliding rod 4 and the bracket 11, and can push and pull the sliding rod 4 better.

[0026] Furthermore, the bracket 11 is fitted with bearings 111, and the rotating rod 12 is welded to the rotating inner ring of a pair of bearings 111, which can improve the sensitivity of the slope measuring instrument used for construction engineering supervision and make the test results more accurate.

[0027] Furthermore, a connecting plate 21 is welded onto the indicator dial 2. The end of the connecting plate 21 away from the indicator dial 2 is welded to the fixing plate 41, and the lower end surface of the indicator dial 2 is higher than the upper end surface of the base 1. Specifically, the indicator dial 2 and the base 1 do not contact each other. When the sliding rod 4 is pulled, the indicator dial 2 will move closer to the pointer 131, which makes it easier to read the value and further reduces the reading error.

[0028] It should be noted that the distance between the indicator 2 and the pointer 131 is greater than the distance between the magnet 42 and the first iron block 122, to prevent the indicator 2 and the pointer 131 from colliding.

[0029] like Figure 4 and Figure 5 As shown, a protective shell 3 is welded onto the base 1, and a transparent wall 33 is embedded in the protective shell 3. A second iron block 32, matching the magnet 42, is welded onto the rear plate of the protective shell 3. The protective shell 3 serves a protective function, preventing damage to the indicator dial 2, the constant balance rod 13, and the pointer 131 during storage. During measurement, pushing the sliding rod 4 causes the magnet 42 to be magnetically attracted to the second iron block 32, preventing the magnetic attraction between the magnet 42 and the first iron block 122 from affecting the rotation of the rotating rod 12.

[0030] Furthermore, a second through hole 3301 matching the sliding rod 4 is provided on the transparent wall 33, and the end of the sliding rod 4 away from the magnet 42 passes through the second through hole 3301. A second handle 44 is heat-fused to the end of the sliding rod 4 away from the magnet 42, and a first handle 31 is welded to the protective shell 3. The second handle 44 allows for easy pushing and pulling of the sliding rod 4, and the first handle 31 allows for better handling of the slope measuring instrument used in construction engineering supervision.

[0031] When using it, place the slope measuring device for construction engineering supervision on the ground to be measured, ensuring that the base 1 is firmly against the ground. After the constant leveling rod 13 is stable, pull the second handle 44 outward. The magnet 42 will then magnetically attach to the first iron block 122, locking the rotating rod 12. At this point, you can pick up the slope measuring device for construction engineering supervision to take a reading. By adjusting the viewing angle, ensure that the observation position is coplanar with the pointer 131, eliminating the potential for reading deviation caused by viewing angle differences, ensuring the accuracy of the measurement data, and providing stable and reliable tool support for high-precision engineering measurement, truly meeting the high requirements of engineering supervision work for measurement accuracy.

[0032] Obviously, the above-described embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, then this utility model also intends to include these modifications and variations.
