Experimental apparatus capable of automatically loading full section of rock

Abstract

The invention provides an experimental apparatus capable of automatically loading the full section of rock. The objective of the invention is to design an experimental apparatus capable of carrying out automatic three-direction static-dynamic coupled loading on rock. The experimental apparatus comprises a fixed outer frame, a lateral hydraulic cylinder group, a top hydraulic cylinder group, a transverse hydraulic cylinder group, a material loading track, a frame-type material loading structure and a self-adaptive elastic roller structure, wherein the lateral hydraulic cylinder group and the top hydraulic cylinder group are fixed on the fixed outer frame; the frame-type material loading structure comprises a motor, a motor fixing plate, a driven fixing plate, a material discharging plate, a connecting rod, a synchronous transmission belt and wheels. According to the invention, the apparatus provides large-tonnage static-dynamic coupled load via the hydraulic cylinder groups so as to realize loading on square rock; the self-adaptive elastic roller structure and frame-type material loading structure enables material loading to be more convenient; the control parts of the apparatus are operated by operators on a host computer, so automation is realized; so the apparatus is a convenient, stable and efficient automatic loading device for rock simulation experiments.

Description

technical field [0001] The invention relates to a loading device, in particular to a rock loading device, which belongs to the field of geomechanics simulation experiments. Background technique [0002] In the context of our country being a mountainous country, with the rapid development of the economy, the supply of resources will conflict with the pace of economic development, and the development of resources will be accelerated. However, the consumption of ground and shallow resources is almost exhausted, so we can only turn to Vigorously excavating deep underground resources, a large number of underground excavation projects have emerged, and the scale and technical difficulty of the projects have also increased in the world. It is inevitable to encounter rocks during the mining process. As the depth of rocks increases, the ground stress will increase exponentially. Therefore, the probability of dynamic disasters such as rockbursts will increase during deep excavation. ...

AI Technical Summary

Problems solved by technology

[0003] Research on a device that can realize full-section loading of rocks has a positive effect on preventing rock bursts during excavation. However, in the existing loading technology, there is no loading system that can provide both dynamic and static loads. It is impossible to simulate the loading of dynamic and static loads on rocks in the ground. The automatic loading experimental device for the full section of rocks of the present invention can provide large tonnage dynamic and static loads, and the force simulation of deep rocks is more accurate and the device is convenient to load.
