Measuring device and method for transformer substation concrete frame stand column perpendicularity

Abstract

A measuring device for the transformer substation concrete frame stand column perpendicularity comprises a long insulation rod (5), a first vernier caliper (1), an aiming point (4), a second vernier caliper (2), an infrared distancer (3) and a circular level (6). The long insulation rod (5) is of the specification length of 2 m, 4 m and the like according to one fifth of the height of an actual component. The first vernier caliper (1) is perpendicularly and fixedly connected to the top of the long rod. The aiming point (4) is arranged on the first vernier caliper downwards. The second vernier caliper (2) is hinged to the bottom of the long rod. The infrared distancer (3) is arranged on the second veriner caliper, and the distance measuring direction is upward. The circular level (6) is arranged on the vernier caliper. The invention further relates to a measuring method of the device. A slant angle alpha can be obtained, the perpendicularity delta equal to tan alpha can be worked out, and the device is high in pertinence, obvious in effect, simple, convenient to use, efficient, safe, capable of being operated with no power failure, simple in measuring operation, high in efficiency and measuring efficiency and free of influences of environment such as wind and rain. The device can be widely popularized for a large amount of pole and tower perpendicularity measurement and building, bridge and water conservancy projects in the large power sector coverage.

Description

technical field [0001] The invention relates to a measuring device for verticality of a substation concrete frame column. The invention also relates to a method for measuring the verticality of the substation concrete frame column by using the device. Background technique [0002] In order to ensure the safety of the existing substation concrete frame, it is necessary to measure the verticality of the frame column for its safety performance testing and evaluation and reliability analysis. Due to the large number of poles and wires in the substation site, the test space is limited, and in order to reduce the power outage time and consider safety factors, rapid detection is very important. At present, the commonly used measurement methods include visual inspection, the combination method of plumb line and scale, the combination method of total station and reflective sheet, the combination method of theodolite and scale, etc. The above method has cumbersome measurement operat...
