Description

Technical Field

[0001] The utility model relates to the field of measurement, and more specifically, to a measurement, adjustment and centering rod device. Background Art

[0002] The centering rod adopts the integrated technology of "laser rangefinder + precision amplification device + display screen", and then uses the controller to process data and output. The design is concise and clear, the operation is simple in actual operation, and the accuracy is high. After many experiments, it can meet the needs of high-precision measurement. However, the measurement of the centering rod will affect the offset of the level bubble during transportation and use, causing the tilt of the centering rod. In order to improve the measurement accuracy, the centering rod needs to be calibrated. The existing total station calibration method requires the installation of two instruments so that the instrument and the prism are roughly at a 90-degree angle. The instrument is about 10 to 20 meters away from the prism, and then the prism is adjusted so that the crosshairs at the tip of the prism coincide with the crosshairs of the instrument eyepiece. If the bubble on the centering rod is not centered, adjust the spiral at the bottom of the bubble to center the bubble. This method wastes time and manpower. Utility Model Content
