AI Technical Summary

Technical Problem

Existing geotechnical tensile testing devices cannot effectively fix geotechnical materials of different sizes, resulting in geotechnical materials easily displaced or shedding during tensile tests, affecting the accuracy and efficiency of test results.

Method used

A geotechnical tensile testing device is designed, including workbench, slider, slider, telescopic rod, support frame, movable groove, movable frame, thread groove, bidirectional thread rod, gear and motor. Through the interaction of these components, fixing and tensile testing of different sizes of geotechnical soil can be achieved.

Benefits of technology

It effectively avoids the problem of displacement or fall off of the geotechnical soil in tensile tests, improves the accuracy and efficiency of the test results, and reduces the labor intensity of the staff.

Abstract

The utility model provides a rock-soil tensile test device, which relates to the technical field of test devices and comprises a workbench, and two chutes are arranged at the top of the workbench. During use, under the interaction of a series of assemblies, when rock soil needs to be fixed, firstly, under the mutual cooperation of a first motor, a first gear, a second gear and a two-way threaded rod, a movable frame can be driven to move in a movable groove; according to the device, the distance between the movable frames can be adjusted according to rock and soil of different sizes, the rock and soil of different sizes can be placed between the movable frames, the practicability of the device is improved, after the rock and soil are placed, a second motor, a connecting device and a threaded lead screw are matched with one another, a fixed plate is driven to move downwards, and the fixed plate is driven to move downwards; therefore, rock and soil of different sizes can be fixed, the problem that the rock and soil displace or fall off in a tensile test is avoided, and the accuracy of the result of the tensile test of the rock and soil is improved.
