Problems solved by technology

The follow-up observation of the high-speed rail must be carried out at night without affecting the daytime operation. The current precision level cannot read the leveling rod at night without a light source, making data observation impossible. Therefore, the leveling rod must be equipped with lighting equipment
The traditional method is artificial lighting. Unstable light sources cause inaccurate or no readings on the level gauge, and the labor cost is high

Abstract

The invention belongs to stadia measurement tools, and in particular relates to a leveling rod for night surveying, aiming at the blank that the current precise leveling rod is not provided with illuminating equipment. The leveling rod for night surveying comprises a leveling rod body 1, an illuminating device 2 and a power 3, wherein the illuminating device 2 is located at one side of the scale panel of the leveling rod body; and the power 3 is connected with the illuminating device 2. Compared with the prior art, the leveling rod for night surveying disclosed by the invention has the advantages that a light source reflects uniformly and is prevented from directly radiating the leveling rod body scale to influence the indications of the leveling rod, so that light rays radiate uniformly and have moderate brightness.

Description

Technical field: [0001] The invention belongs to a sight distance measuring tool, and further relates to a leveling rod for nighttime survey. Background technique: [0002] With the continuous maturity of high-speed rail technology, high-speed railways in operation need follow-up observations to ensure their safety, smoothness and stability. The follow-up observation of the high-speed rail must be carried out at night without affecting the daytime operation. The current precision level cannot read the leveling rod at night without a light source, making data observation impossible. Therefore, the leveling rod must be equipped with lighting equipment . The traditional method is artificial lighting. Unstable light sources cause inaccurate or no readings on the level gauge, and the labor cost is high. Therefore, there is an urgent need for a lighting device that can be fixed on the level to meet the observation requirements of the level, and can be adjusted with the length of...
