Hydraulic Support Model Test Load Equipment and its Hydraulic Control System

Abstract

Hydraulic support is an important equipment of mechanization caving coal in modernization coal mine. Hydraulic support strength test is a key link in hydraulic support design. Based on the similarity theory, the displacement, stress and strain information of test measured from hydraulic support model test can be popularized to hydraulic support prototype. This has an important significance on successful pass in prototype hydraulic support strength test and quicker and better designing eligible hydraulic support. The construction of load equipment and hydraulic control system of hydraulic support model test provides a practical and convenient research way of hydraulic support model test.
