AI Technical Summary

Technical Problem

In existing technologies, when measuring wall corners, it is necessary to redeploy surveying equipment to measure both horizontal and solid angles separately, which leads to a waste of time and manpower and increases operational complexity. This can cause project delays and errors, especially in complex or large-scale building projects.

Method used

An easily adjustable corner surveying fixture was designed, which consists of a support frame, a 3D surveying rod, a 2D surveying rod, a positioning rod, and a telescopic component. The 3D and 2D surveying rods can be quickly extended and retracted through a threaded rod and gear structure, simplifying the operation process.

Benefits of technology

This technology enables the measurement of solid angles without the need for device redeployment, reducing time consumption and errors, lowering operational complexity, and improving measurement efficiency.

Abstract

The utility model relates to the field of wall corner surveying and mapping tools, and discloses a wall corner surveying and mapping fixing frame convenient to adjust, which comprises a support frame, a three-dimensional surveying and mapping rod is hinged to the top end of the outer surface of the front end of the support frame, a threaded rod A is rotatably connected to the top end of the inner surface of the support frame, and a hinge piece A is in threaded connection with the outer surface of the threaded rod A; the top end of the inner surface of the hinge piece A is hinged to the bottom end of the inner surface of a three-dimensional surveying and mapping rod through a hinge rod B. A plane surveying and mapping rod is hinged to the front end of the inner surface of the supporting frame, and a threaded rod B is rotationally connected to the bottom end of the inner surface of the supporting frame. According to the wall corner surveying and mapping device, the three-dimensional surveying and mapping rod is arranged, after the plane angle of a wall corner is measured, the threaded rod A is operated to independently drive the three-dimensional surveying and mapping rod to be unfolded upwards so as to carry out surveying and mapping on the three-dimensional angle of the wall corner, and the effects of time loss and surveying and mapping errors generated by redeploying a surveying and mapping device are avoided.
