Abstract

The invention belongs to the technical field of slip starting angle measurement, and discloses a portable starting angle measuring device, which comprises a base, a rotating tray, an arc rotating guide rod, a protractor ruler and a pointer. The rotating tray is connected with the base in a pivoted mode through a pivot shaft, the first end of the arc rotating guide rod is hinged to the base througha hinge piece, and a rod body of the arc rotating guide rod is embedded in the rotating tray in a sliding mode; the protractor ruler is fixed on the base, the pointer is fixed on the rotating tray, and the rotating center of the pointer and the original point of the protractor ruler are both arranged at the pivot shaft and used for measuring the rotating angle of the rotating tray relative to thebase. The slip starting angle measuring device provided by the invention can improve the measuring precision and reliability.

Description

technical field [0001] The invention relates to the technical field of slip start angle measurement, in particular to a portable start angle measurement device. Background technique [0002] In the prior art, the shear joint surface slip of the rock mass is related to the environment, and there are many influencing factors. In order to study the sliding effect of the rock mass shear joint surface, the environmental factors of the rock mass are usually simulated for experiments; however, the simulated environmental factors in the prior art are too single, which leads to the reliability of the experimental results and the correlation with various factors poor. Contents of the invention [0003] The invention provides a slip start angle measurement device, which solves the technical problems of poor reliability and poor convenience in the start angle measurement test in the prior art. [0004] In order to solve the above-mentioned technical problems, the present invention p...
