Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying, in particular to a leveling staff setting device for engineering surveying. Background Art

[0002] In the field of engineering surveying, a leveling staff is an essential key tool for carrying out leveling surveys. During the leveling survey process, it is necessary to obtain an accurate horizontal line of sight by adjusting the level, and then read the values with the leveling staff kept in a plumb state at both ends to calculate the elevation difference between two points. Currently, in the actual operation of leveling surveys, the setting and holding of the leveling staff generally rely on manual labor. During this process, to ensure that the leveling staff reaches an ideal plumb state, the person setting the staff needs to continuously adjust and control the circular spirit level on the side of the leveling staff to make the bubble centered. This step requires the person setting the staff to remain relatively stationary until all the observation tasks at the current survey station are completed.

[0003] However, the current design and usage methods of leveling staffs have multiple drawbacks that need to be solved urgently. First of all, in order to improve the portability and the stability of holding the staff, handrails are often installed on the sides of the leveling staff. However, most of these handrails are made of plastic materials, and their durability is limited. They are easily damaged or detached due to being bumped during daily use and storage, thus affecting the smooth progress of the measurement work. Secondly, the handrail designs on both sides of the leveling staff often have problems such as too close horizontal spacing and non-adjustable height. This makes it extremely difficult to continuously hold the staff for a long time, poses a great burden on the surveyors, and also reduces the working efficiency of the leveling survey. In addition, as a high-precision measurement tool, the leveling staff will inevitably encounter various collisions during storage and handling, which often affects the accuracy of the circular spirit level, resulting in frequent calibration of the spirit level during actual measurements, increasing the complexity and time cost of the measurement.

[0004] In view of the above problems, the accuracy, convenience, and stability of setting the leveling staff all face severe challenges, which undoubtedly have an adverse impact on the observation accuracy and overall efficiency of the leveling survey. Therefore, it is particularly important and urgent to develop a new type of leveling staff setting device for engineering surveying that can effectively solve the problems of difficult setting and low efficiency of the leveling staff. The utility model emerges under this background, aiming to achieve the rapid, accurate setting and stable holding of the leveling staff through technological innovation and optimized design, thereby improving the overall efficiency of the leveling survey.

Specific embodiments

[0043] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0044] Embodiment 1

[0045] As Figures 1 to 10 shown, the leveling staff connecting device 2 has a groove structure for tightly connecting with the leveling staff 1. One side of the groove structure is fixedly connected to the back plate 24, and the other side realizes horizontal movement through a sliding component installed in the chute of the back plate 24 to achieve connection with the leveling staff 1 in the width direction; pressing components are arranged at the tops of both sides of the groove for connecting with the leveling staff 1 in the thickness direction;

[0046] Two handles 4 are fixedly connected to the back plate 24 of the leveling staff connecting device 2. The two handles 4 are connected by a horizontal support plate 5 in the middle. Two mutually perpendicular tubular levels 6 are horizontally inlaid above the support plate 5 for quickly making the leveling staff 1 strictly plumb;

[0047] Symmetrically distributed cylindrical threaded sleeves 7 are fixed to the lower side of the back plate 24 of the leveling staff connecting device 2 for threaded connection with two support frames 8 to form a stable structure and maintain the static stability of the leveling staff 1.

[0048] In this embodiment, the leveling staff connecting device 2 has a trough-shaped structure, including a back plate 24. On one side of the back plate 24, a reference block 21 is fixedly installed. One width side of the leveling staff 1 is placed flush and close to it. On the other side, a sliding component is slidably installed in the chute of the back plate 24, and it slides horizontally in the chute of the back plate 24 to achieve flexible connection with the leveling staff 1 in the width direction.

[0049] Furthermore, the sliding component includes a slider 22, and a screw rod 25 is installed at its bottom. The screw rod 25 is inserted into the groove of the back plate 24, and a nut 3 is screwed thereon to lock the slider 22.

[0050] Furthermore, pressing components are installed on the tops of both the reference block 21 and the slider 22. The pressing component includes a pressing block 23. The pressing block 23 is detachably installed on the tops of the reference block 21 and the slider 22 through bolts 26. The pressing block 23 presses on the top of the leveling staff 1, and by tightening the bolts 26, the tight connection with the leveling staff 1 in the thickness direction is achieved. When the bolts 26 are loosened, the leveling staff 1 can be taken out and replaced.

[0051] Furthermore, the handle 4 has a U-shaped structure, with anti-slip textures on its surface.

[0052] Furthermore, two tubular levels 6 are inlaid on the top surface of the horizontal support plate 5. The two tubular levels 6 are respectively horizontal and vertical with the back plate 24, and are used to quickly level the leveling staff 1.

[0053] Furthermore, after the support frame 8 is connected to the leveling staff connecting device 2 through a threaded sleeve 7, it forms a static stable structure with the leveling staff 1. The support frame 8 is divided into two upper and lower sections, and the length is adjusted by pressing the middle connecting handle 9 to meet different measurement requirements.

[0054] Furthermore, the support frame 8 is a hollow aluminum alloy tube, which is used to support the leveling staff 1 to maintain static stability during the measurement process.

[0055] Furthermore, the connecting handle 9 includes an elastic plunger 92 that connects and clamps the upper and lower sections of the support frame 8. The elastic plunger 92 is covered with a protective sleeve 91, and the protective sleeve 91 entirely covers the connection part of the upper and lower sections of the support frame 8.

[0056] Furthermore, the elastic plunger 92 includes a housing. A spring is fixed inside the housing, and a bead column body is fixed above the spring. The bead column body is a solid part with a cylinder at the bottom and a hemisphere at the top.

[0057] During specific use: After the trial installation and acceptance of a leveling staff erecting device for engineering survey are qualified, when it is put into use, first adjust the length of the support frame 8 to an appropriate value to ensure stable support; then place the leveling staff 1 at the required measurement position, and place the leveling staff 1 in the groove of the leveling staff connecting device 2, with one side flush and tightly against the reference block 21. Slide the slider 22 to clamp the leveling staff 1, and then tighten the nut 3 to fix the leveling staff 1 in the width direction. Rotate and press down the pressing block 23 so that the hypotenuse of the pressing block 23 is above the thickness of the leveling staff 1, and tighten the bolt 26 to press the pressing block 23 tightly, and press the leveling staff 1 in the thickness direction through the pressing block 23. Then, next, use the pressing assembly to fix the leveling staff 1 and make it fit tightly by rotating the bolt 26; subsequently, observe and adjust the two tube levels 6 to ensure that the leveling staff 1 is in a completely horizontal state; finally, the operator holds the handle 4 with both hands and can start precise measurement work.

[0058] Embodiment 2

[0059] In another preferred embodiment, on the basis of Embodiment 1, as Figures 1 to 10 shown, a basic leveling staff erecting device for engineering survey, including components such as a leveling staff connecting device 2, a handle 4, a horizontal support plate 5, a tube level 6, a support rod 8, etc.

[0060] First, place the leveling staff 1 in the groove of the leveling staff connecting device 2. The connecting device has a groove-shaped structure, in which the fixed part 21 is tightly fixed to the back plate 24, and the sliding component can slide horizontally through the chute on the back plate 24; by adjusting the ruler width pushing screw 25, control the left and right movement of the slider 22 to make it closely contact and fix with the leveling staff 1 in the width direction; at the same time, use the ruler thickness pressing block 23 and the tightening bolt 26 to further fasten the leveling staff 1 in the thickness direction to ensure a stable connection between the device and the leveling staff 1.

[0061] At the rear side of the back plate 24 of the leveling staff connecting device 2, two handles 4 are fixedly connected. These two handles have a U-shaped structure and are connected by the middle horizontal support plate 5; two tube levels 6 are inlaid on the top surface of the horizontal support plate 5, and these two tube levels 6 are respectively arranged horizontally and vertically with respect to the back plate 24, and are used to quickly level the leveling staff 1 precisely.

[0062] To further improve the stability of the erecting device, threaded connection holes are provided at the left and right edges of the lower side of the back plate 24, and these connection holes are used to install the support frame 8; the support frame 8 is made of a hollow aluminum alloy tube, which is divided into two upper and lower sections and is equipped with a connecting handle 9; by rotating the connecting handle 9, the total length of the support rod can be adjusted to adapt to different measurement environments and requirements.

[0063] During use, the operator can hold the handle 4 with both hands and gently shake the device with the ground fulcrum where the leveling staff 1 is located as the center until the bubbles in both tubular spirit levels 6 are centered. At this time, it indicates that the leveling staff is in a strictly plumb state. This design not only improves the accuracy of setting up the staff but also avoids the inconvenience caused by directly holding the staff, which is beneficial for long-term continuous observation operations.

[0064] Embodiment 3

[0065] In another preferred embodiment, based on Embodiments 1 and 2, as Figures 1 to 10 shown, the leveling staff setting-up device with a telescopic support frame adds the function of a detachable telescopic support frame 8 on the basis of Embodiment 2 to cope with the scenario of static leveling staff observation.

[0066] Specifically, two telescopic support frames 8 are installed in the threaded connection holes on the lower side of the back plate 24 of the leveling staff connecting device. These support frames 8 are connected to the main body device through threaded sleeves 7 and their lengths are controlled by connection handles 9. When static leveling staff setting-up is required, the support frames 8 are extended to an appropriate length to form a stable triangular support structure with the leveling staff 1, thereby realizing the static stability of the leveling staff. This design not only avoids the influence of shaking during the process of manually holding the staff on the observation accuracy but also can complete the leveling measurement in the absence of a staff-holding person.

[0067] In addition, the telescopic support frame 8 in this embodiment also has the advantage of portability. When not in use, the support frame 8 can be shortened and disassembled to reduce the volume and weight of the device, making it convenient to carry and store.

[0068] In a preferred solution, the leveling staff connecting device 2 has a trough-shaped structure, including a back plate 24. On one side of the back plate 24, a reference block 21 is fixedly installed, and one side of the width of the leveling staff 1 is placed flush against it. On the other side, a sliding component is slidably installed in the chute of the back plate 24, and it slides horizontally in the chute of the back plate 24 to achieve flexible connection with the leveling staff 1 in the width direction. The above settings effectively ensure the stable fitting and quick adjustment of the leveling staff 1 and the leveling staff connecting device 2 in different working environments, improving the measurement accuracy and operation convenience. At the same time, the design of the sliding component also enhances the durability and flexibility of the overall device.

[0069] In a preferred embodiment, the sliding assembly includes a slider 22, at the bottom of which a screw rod 25 is installed. The screw rod 25 is inserted into a groove of the back plate 24, and a nut 3 is screwed thereon to lock the slider 22. When the nut 3 is loosened, the slider 22 moves in the width direction to achieve a tight connection between the device and the leveling staff 1. The above settings ensure that the device can be flexibly adjusted according to the width of the body of the leveling staff 1, achieving seamless docking, improving the accuracy and convenience of measurement. At the same time, this design also facilitates installation and disassembly, enhancing the overall practicality and maintenance efficiency of the equipment.

[0070] In a preferred embodiment, pressing components are installed on the tops of both the reference block 21 and the slider 22. The pressing component includes a pressing block 23, which is detachably installed on the tops of the reference block 21 and the slider 22 through bolts 26. The pressing block 23 presses on the top of the leveling staff 1, and by tightening the bolts 26, a tight connection with the leveling staff 1 in the thickness direction is achieved. When the bolts 26 are loosened, the leveling staff 1 can be taken out and replaced. The above settings make the replacement and installation process of the leveling staff 1 simple and fast, without the need for complex tools, improving the operation efficiency. At the same time, the design of the pressing component ensures the stability of the leveling staff during the measurement process, reducing the possibility of error generation.

[0071] In a preferred embodiment, the handle 4 is of a U-shaped structure, with anti-slip textures on its surface. It is symmetrically arranged on the rear side of the back plate 24 of the leveling staff connecting device 2 on the left and right, and is connected through the middle horizontal support plate 5, facilitating the user to hold the staff continuously for a long time. The above settings not only ensure the stability of holding the staff but also effectively disperse the hand pressure, enhancing the operation comfort. In addition, the anti-slip texture design on the surface of the handle 4 further enhances the firmness of gripping, ensuring precise control even in harsh environments.

[0072] In a preferred embodiment, two tubular spirit levels 6 are inlaid on the top surface of the horizontal support plate 5. The two tubular spirit levels 6 are respectively horizontal and vertical to the back plate 24, and are used to quickly level the leveling staff 1. The above settings not only improve the measurement accuracy but also simplify the operation process. The user can directly observe the position of the bubble in the tubular spirit level 6 and quickly adjust the horizontal support plate 5 to a horizontal state to ensure the precise verticality of the leveling staff 1, improving the measurement efficiency and accuracy.

[0073] In a preferred embodiment, after the support frame 8 is connected to the leveling staff connecting device 2 through a threaded sleeve 7, it forms a static stable structure with the leveling staff 1. The support frame 8 is divided into two sections, and the length is adjusted by pressing the middle connecting handle 9 to meet different measurement requirements. The above settings make the leveling staff 1 system highly flexible and adaptable. Whether on a flat ground or in a complex terrain, it can be quickly adjusted to the best measurement state, improving the operation efficiency and measurement accuracy.

[0074] In a preferred embodiment, the support frame 8 is a hollow aluminum alloy tube, which is used to support the leveling staff 1 to maintain static stability during the measurement process; with the above arrangement, the bottom of the leveling staff 1 is firmly combined with the support frame 8 through a precise threaded connector to ensure the accuracy of verticality and horizontality; at the same time, the setting of the aluminum alloy tube material of the support frame 8 increases its corrosion resistance and enhances its durability and reliability for outdoor use.

[0075] In a preferred embodiment, the connecting handle 9 includes an elastic plunger 92 that connects and clamps the upper and lower sections of the support frame 8. The elastic plunger 92 is covered with a protective sleeve 91, and the protective sleeve 91 entirely covers the connection between the upper and lower sections of the support frame 8; with the above arrangement, it effectively prevents the intrusion of dust and impurities, improving the durability and stability of the device; at the same time, the design of the elastic plunger 92 makes the handle connection more stable, ensuring the safety and reliability of the support frame 8 during use.

[0076] In a preferred embodiment, the elastic plunger 92 includes a housing, a spring is fixed inside the housing, and a bead column is fixed above the spring. The bead column is a solid part with a cylindrical shape at the bottom and a hemispherical shape at the top; with the above arrangement, when the elastic plunger 92 is subjected to an external force, the bead column can move flexibly in the housing and compress the spring, and the hemispherical design helps to disperse the pressure, improving the stability and durability of the overall structure.

[0077] In summary, a leveling staff standing device for engineering survey proposed by the present utility model solves the core problems such as difficult standing, low efficiency, and difficult-to-guarantee accuracy during the standing process of the leveling staff in the field of engineering survey, and overcomes the limitations of the existing leveling staff standing method that relies on manual labor, unstable accuracy, and inconvenient operation; through the combination of the groove structure, sliding block, and bolt, the present utility model realizes the flexible adjustment of the leveling staff connecting device 2 in the width and thickness directions, ensuring the tight connection of the device with leveling staffs 1 of different specifications, which is not available in the traditional leveling staff fixing method; its integrated leveling and support design integrates the tubular level 6, handrail, and support frame 8 into one device, which not only simplifies the operation process but also improves the stability and accuracy of leveling and support, and this design is rare in the existing leveling staff standing devices 2; through quick leveling and stable support, the present device effectively reduces the errors and unstable factors during the standing process, thereby improving the efficiency and accuracy of leveling survey, bringing significant technological progress to the field of engineering survey; the height of the present device and the length of the support frame are both adjustable, enabling it to adapt to different usage scenarios and user requirements, and being convenient to carry and install, greatly improving the convenience of use; with its innovative structural design, high flexibility, and easy operation, the leveling staff standing device provides strong technical support for engineering survey, and is expected to become a model of industry standards in the future, promoting the development of engineering survey technology towards higher accuracy and higher efficiency.
