Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a docking type leveling rod and leveler calibration device. Background Art

[0002] With the development of modern surveying and mapping equipment, the use of digital levels and barcode leveling scales has promoted the development of leveling measurement towards automation, high precision and high efficiency. Leveling scales are widely used in the field of measurement. They are usually made of aluminum alloy to ensure their strength and lightness, while the tape is made of high-precision indium tile material to ensure the accuracy of measurement. Its design is very regular, the ruler is straight, and the front, side and bottom surfaces are all flat to ensure stability and accuracy during the measurement process. The level is fixed behind the ruler through a special frame, usually one is installed near the bottom and middle of the ruler, and is used for calibration and correction during the measurement process.

[0003] When using the level rod and measuring rod, which are commonly used tools in engineering surveying, the ruler and the measuring rod should be kept vertical. The circular level on it is the vertical indicator. When the vertical axis of the circular level is parallel to the center line of the level rod and the measuring rod, and the bubble of the circular level is centered, the ruler and the measuring rod are in a vertical state.

[0004] During the transportation of the level rod, the vertical axis of the circular level may shift due to vibration or improper operation during transportation, causing it to no longer be parallel to the center line of the level rod and the measuring rod. This shift will result in the ruler and the measuring rod no longer remaining vertical even if the bubble of the circular level is centered, thereby introducing a large measurement error and making it impossible for the rod to continue to perform accurate measurements. Therefore, it is necessary to provide a docking level rod level calibration device to complete the calibration of the level. Utility Model Content
