Problems solved by technology
Human factors and arbitrariness are relatively large, and accuracy is difficult to guarantee
In reality, because the distance of the anchor screws exceeds the error value, the phenomenon of rework also occurs from time to time
Furthermore, when there are prominent obstacles between the measured points, traditional tools such as tape measure, tape measure, protractor, etc. are difficult to use, and only indirect methods can be used for measurement, which is time-consuming, laborious and inaccurate

The invention relates to a triangular stereoscopic measuring instrument which can be used to measure the distance and the angle within a narrow range in power engineering and belongs to the technical field of measuring instruments. The triangular stereoscopic measuring instrument comprises a fixed disk and three support rods of the same height, the support rods are fixed to the bottom of the fixed disk, the top of the fixed disk is provided with a gradiometer, the bottom of the fixed disk is provide with a fixed guide rail and a movable guide rail, the bottoms of the fixed guide rail and the movable guide rail are provided with guide rail grooves respectively, one end of the movable guide rail is mounted in the fixed guide rail and can move to and fro in the groove of the fixed guide rail, the groove of the fixed guide rail is internally provided with two connecting balls, the two connecting balls are respectively placed at the two ends of the movable guide rail, the groove of the movable guide rail is provided with another connecting ball which can slide in the groove of the movable guide rail, and the three connecting balls are fixed to the support rods respectively. The triangular stereoscopic measuring instrument of the invention can be applied to power engineering, is simple in operation, high in measuring precision and capable of measure the distance and the angle.
Description
technical field [0001] The invention belongs to the technical field of measuring instruments, and in particular relates to an instrument suitable for measuring distances and angles within a small range in electric power engineering. Background technique [0002] In the process of electric power engineering construction, it is often necessary to measure the angle and length in a small range, such as the distance and angle between the foundation screws of the line pole tower, the distance and angle between the foundation installation points of the substation, the position of the cement pole and so on. In this case, it is troublesome and inconvenient to use a total station to measure, and secondly, the error of the measurement result of the total station for a short distance is large, which is not practical. Therefore, in actual work, the original tool tape measure is often used to measure the distance and then calculate the angle. Human factors and arbitrariness are relativel...
