The invention discloses a multidirectional measurement and installing device of a displacement sensor, and belongs to the technical field of civil engineering test and measurement. The multidirectional measurement and installing device comprises a set of sensor outer sleeve hinging base and a set of sensor mandrel end part hinging base. Each of the sensor outer sleeve hinging base and the sensor mandrel end part hinging base is formed by a corresponding hinging device and a fixing device. The device can avoid sensor damage caused by improper connection method during the testing process, and guarantee relative accuracy of the measurement data. The device can realize the flexible selection of the sensor at fixing points on a reference frame and a test piece, and is convenient to install and measure.
Description
technical field [0001] The invention belongs to the technical field of civil engineering test measurement, and relates to a rod type displacement sensor installation device for one-way, two-way or multi-way measurement. Background technique [0002] In civil engineering tests, displacement sensors are mainly used to measure the deformation information of specimens. The accuracy of the information measured by the displacement sensor can directly affect the success or failure of civil engineering tests. At this stage, most of the displacement sensors equipped in civil engineering laboratories can only measure unidirectional displacement information. When a two-way or multi-directional test is required, if such a displacement sensor is fixed on the test piece and the corresponding displacement sensor fixing support, it is easy to cause damage to the displacement sensor. In order to solve this problem, the common methods can be classified into the following two categories: 1) ...
