Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and more specifically, to a leveling auxiliary device. Background Technology

[0002] In engineering construction and topographic surveying, rapid and efficient leveling is crucial for ensuring project quality and the accuracy of topographic maps. Traditional leveling uses a level instrument and a leveling rod to determine the elevation differences between different points, thereby calculating the elevation of each point. This method requires that the distance from the level instrument to the foresight and backsight rods be equal to ensure the accuracy of the measurement results. However, in actual measurement processes, workers need to constantly adjust the positions of the level instrument and leveling rod to maintain equal foresight and backsight distances. This not only increases the complexity of the work but may also introduce additional measurement errors, affecting work efficiency and data accuracy.

[0003] To address this issue, existing technologies have proposed several solutions, such as using laser rangefinders or other electronic measuring devices to assist in measurement. These devices can provide more accurate distance measurements and reduce the possibility of human error. However, these advanced devices are often expensive, complex to operate, and inconvenient for rapid deployment and use in the field. Furthermore, these devices typically only provide distance data after the measurement is completed, failing to provide real-time feedback to operators, making it difficult for them to adjust the instrument position promptly during the measurement process.

[0004] Another challenge is ensuring the level is horizontal during leveling measurements. Traditionally, this requires manual operation, achieved by rotating a leveling knob. This process is not only time-consuming but also highly dependent on the operator's skill and experience, and can introduce additional errors.

[0005] Therefore, it is particularly important to develop a technology that can simplify the leveling process and improve measurement accuracy and efficiency. Utility Model Content

[0011] The rangefinder plate is provided in two, and the two rangefinder plates are respectively snapped into the two fixing components. Each of the two rangefinder plates is provided with a signal receiver. A display panel and a switch button are provided on the side of the rangefinder plate away from the support body. A battery electrically connected to the display panel and the switch button is provided inside the rangefinder plate.

[0012] A gimbal base is provided on the top of the support body, and an electronic level and controller are installed inside the gimbal base. The top of the gimbal base is used to fix the bottom of the level. The gimbal base adjusts the attitude in real time to keep the level in a horizontal state.

[0013] In some embodiments, the base plate is provided with threaded holes, and the base plate is fixedly connected to the top of the tripod through the threaded holes.

[0014] In some embodiments, the base plate coincides with the axis of the connecting column, and the charging port is electrically connected to the battery.

[0015] In some embodiments, the fixing component includes:

[0016] A fixing plate is provided along the length of the support body and is fixedly connected to the side wall of the support body;

[0017] A limiting block is provided at the bottom of the fixing plate, and the side wall of the limiting block is fixedly connected to the side wall of the support.

[0018] In some embodiments, the cross-section of the fixing plate is a T-shaped structure.

[0019] In some embodiments, the bottom of the limiting block is on the same horizontal line as the bottom of the support.

[0020] In some embodiments, a groove matching the fixing plate is provided on one side of the ranging plate.

[0021] In some embodiments, the gimbal base includes:

[0022] Electric telescopic columns, four of which are provided, and the four electric telescopic columns are respectively arranged at the four corners of the top of the support body. The bottom of the electric telescopic column is fixedly connected to the top of the support body;

[0023] Fixed base, a connecting block is fixedly connected to the top of the fixed base. The outer surface of the connecting block is provided with an external thread. The fixed base is fixedly connected to the bottom of the level by the connecting block arranged at the top. The bottom of the fixed base is fixedly connected to the tops of the four electric telescopic columns. An electronic level and a controller are arranged inside the fixed base.

[0024] In some embodiments, the axis of the fixed base coincides with that of the support body, and the electric telescopic column is electrically connected to the electronic level, the controller and the storage battery.

[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0027] By arranging an electronic level and a controller inside the pan-tilt base, and controlling the four electric telescopic columns to work in real time, it can ensure that the level is always in a horizontal state. This automatic horizontal adjustment eliminates the errors in manual operation, such as the slight deviations that may be brought by manually rotating the horizontal knob, thereby improving the accuracy of leveling measurement. Automatic horizontal adjustment means that there is no need for manual intervention to adjust the horizontal state of the level during the measurement process. This not only reduces the operation steps, but also greatly shortens the measurement preparation time, making the whole measurement process more efficient and fast. A signal transmitter is arranged at the bottom of the pan-tilt base, cooperating with the switch button and the display panel on the two detachable ranging plates at both ends. When the two ranging plates are removed from the fixing components and respectively adhered to the bar code rulers matching the level, the staff can directly know the distance between the bar code ruler and the level through the display panel. This design makes the measurement process more intuitive and convenient. The staff can view the stadia information displayed on the display panel in real time to determine the distance between the bar code ruler and the level, enabling them to adjust the position and state of the instrument in a timely manner according to the actual situation. If it is found that the stadia of the two bar code rulers are not equal, the staff can immediately take measures to adjust, avoiding measurement errors and accuracy exceeding limits caused by unequal stadia. This helps to improve the accuracy and consistency of the measurement results.
