Abstract

The invention provides a locating tool for solving the problems that a traditional measurement method has high workload, low working efficiency and inaccuracy in location and requires more equipment in datum point location. The locating tool comprises a prism supporting device, a point punching device, a connecting rod and a beating plate, wherein the point punching device is arranged inside the prism supporting device, a sphereprism is arranged on the prism supporting device, the connecting rod is fixedly connected with the point punching device by the prism supporting device, and the beating plate is fixedly connected with the top end of the connecting rod. The locating tool can reduce the investment of infrastructures under the premise of ensuring the construction quality, reduce the operation steps, reduce the workload of workers, improve the working efficiency and shorten the construction period when being used for determining the datum point during installation.

Description

technical field [0001] The invention relates to a measurement and positioning tool in the installation process of a nuclear power plant, in particular to a precision positioning tool for setting a measurement reference point. Background technique [0002] With the application of engineering measurement technology more and more widely in nuclear power installation projects, the dependence on measurement reference points is getting higher and higher when installing various professional equipment in nuclear power plants. In the field of nuclear power installation, the equipment to be installed is designed with fixed installation positions in the plant. These positions are generally represented on the design drawings by coordinate points, axes, angles, etc. The measurement reference points are to help construction personnel in the plant. It is convenient to find out the coordinate points made by the installation position. If there is an error or error in these coordinate points,...
