Problems solved by technology

[0003] At present, during the pre-assembly process of arc gates in the factory, the coaxiality of multiple hinges cannot be measured intuitively. Using conventional total stations for measurement, the actual measurement accuracy cannot meet the requirements; high-precision total stations are expensive and affected by the environment. Factors have greater influence

Description

technical field [0001] The invention relates to a device and method for adjusting and detecting the coaxiality of multiple hinges, which belongs to the technical field of manufacture and installation of arc gates, and is used for measuring the coaxiality of multiple hinges during the vertical assembly process of arc gates of hydropower stations. Background technique [0002] In hydropower and water conservancy projects, arc-shaped working gates are often used in dam water-retaining and flood-discharging structures. The arc-shaped gate generally adopts the form of two hinges. In the arc-shaped work of the flood discharge tunnel of Baihetan Hydropower Station, the form of three hinges is used. The working gate will bear a large water pressure during the opening and closing process, and has high requirements on the coaxiality of the hinge. Therefore, the curved gate must be pre-assembled as a whole before leaving the factory. One of the important data of group test. [0003] A...
