Multidirectional displacement measuring device

Abstract

The invention discloses a multidirectional displacement measuring device, which relates to the technical field of displacement measuring devices, and comprises a first connecting piece, a second connecting piece, an angle measuring assembly and a displacement meter, wherein the first connecting piece and the second connecting piece are fixedly connected to a measured object. The angle measuring assembly is fixedly connected with the other end of the displacement meter, when a structure is displaced, the displacement amount generated in the length direction of the displacement meter can be obtained through the displacement meter, and the rotating angles of the displacement meter on the vertical plane and the horizontal plane are obtained through the first angle sensor and the second angle sensor. Displacement of the structure in multiple directions is obtained through simple conversion, and multidirectional displacement measurement is achieved. Because the other end, connected with theangle measurement assembly, of the displacement meter has degrees of freedom in the vertical direction and the horizontal direction, when the displacement direction of the measured structure object isinconsistent with the length direction of the displacement meter, the other end of the displacement meter can change the spatial position under the displacement effect of the structure object; and shearing force damaging the displacement meter is prevented from being generated on the displacement meter.

Description

technical field [0001] The invention relates to a displacement measuring device, in particular to a multidirectional displacement measuring device. Background technique [0002] The displacement meter is often used for long-term measurement of the opening and closing degree of expansion joints or cracks of hydraulic structures or other concrete structures, and can also be used to measure the displacement, subsidence, Strain, slip. [0003] The measuring rod of the displacement meter can expand and contract along the axial direction of the displacement meter. When the position of the measuring rod changes, the electrical signal output by the inductance coil inside the displacement meter body also changes accordingly, and the displacement data (such as figure 1 shown). Therefore, the general displacement meter can only measure the displacement in one direction along the axis of the displacement meter, and cannot measure the displacement of the structure in multiple direction...

AI Technical Summary

Problems solved by technology

Therefore, the general displacement meter can only measure the displacement in one direction along the axis of the displacement meter, and cannot measure the displacement of the structure in multiple directions at the same time.

And when the measuring point has displacement in multiple directions, the ordinary one-way displacement meter not only cannot measure the accurate displacement of the structure, but also may be damaged by shear force due to the inconsistency between the structural displacement direction and the displacement direction of the displacement meter.
