Double-station anchor cable static tensile mechanical property test device

Abstract

The invention provides a double-station anchor cable static tensile mechanical property test device. The device comprises a first test station which carries out static tensile testing on a first sample and a second test station which carries out static tensile testing on a second sample. One of the first sample and the second sample is a PR anchor, and the other is an NPR anchor. The device further comprises a display device communicably connected with the test device. The display device comprises a first display module which displays the real-time test curve of the first sample and a second display module which displays the real-time test curve of the second sample. The device further comprises a control device communicably connected with the test device and the display device. Accordingto the invention, the device can simultaneously perform static tensile testing on the NPR anchor cable and the PR anchor cable in the same test environment to study the mechanical problems thereof, and can simultaneously visually display the mechanical variation curves of two different types of anchor cables through the first display module and the second display module, and compares and analyzesthe mechanical properties thereof.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a double-station anchor cable static tensile mechanical characteristic test equipment. Background technique [0002] As a large mining country, my country has always had high rock mass deformation disasters caused by mining. These disasters caused a lot of loss of life and property, and seriously restricted the safe and efficient development of mineral resources. [0003] Studies have shown that most rock mass disasters develop from small deformation to nonlinear large deformation, which leads to disasters. The existing engineering control steel materials are materials with Poisson's ratio effect (Poisson Ratio materials, referred to as PR materials). Since these materials are still traditional materials, the relationship between their working resistance and displacement is the traditional elastic deformation-strain strengthening- In strain softening mode, t...

AI Technical Summary

Problems solved by technology

However, the current test device can only perform static tensile tests on one NPR anchor cable or PR anchor cable, and cannot simultaneously test the NPR anchor cable under the same equipment environment, with the same loading rate and loading force. Experimental research on the static tensile characteristics and laws of PR anchor cables

Moreover, it is impossible to visually display the mechanical change curves of two different types of anchor cables at the same time.
