Introduction: Rock electric shear force direct shear device according to the national standard "Highway Engineering Rock Test Procedures" (JTG F41-2005), "Hydraulic and Hydraulic Engineering Rock Test Procedures" (SL264-2001) of the provisions of the developed and mainly applied to the rock structure surface (Such as the joint surface, the layer inside, the inside of the sheet, the fracture surface, etc.), the direct shear test of the rock itself, concrete or mortar and rock cemented surface, and the shear strength test of the interface between concrete and other materials. Its structural performance in full compliance with test specifications. Features: 1, automatic control of the computer, that is, speed, force, displacement and other parameters are controlled in the computer display, and automatically in the database analysis, calculation. 2, the test process real-time record test curve, display and save, high-speed sampling; 3, data, report processing capabilities, to provide users with a graphical report for the exclusive layout editing tools, with flexible operation, easy to learn characteristics, can easily print test curves and test values; 4, real-time display of the current law, tangential force value, peak, test process information, the current displacement. 5, the software has a displacement, force value automatically cleared system, eliminating the artificial reading error and other factors. 6, with overload protection, when the force value or displacement exceeds the rated theoretical value of the testing machine, automatically uninstall and stop the test. 7, each test area, height, ambient temperature and other parameters can be changed or filled out according to the actual situation. 8, double sets of system control, that is, manual control system and computer automatic control system. Easy to change, to ensure that the computer virus, can not boot and other objective factors exist, the work will not be affected. 9, the test process can be edited by the operator based on the actual situation, write the program is simple and convenient. 10, packing pressure point can be set at any point, any rate of each stage set, dwell time arbitrarily set to meet the preset conditions automatically switch to the next stage. Technical Parameters: Normal rated pressure: F ≤ 300KN Tangential pressure rating: F ≤ 500KN Normal space: ≤ 450mm Horizontal space: ≤200mm Shear load speed V: 0.1 ~ 30KN / S (can be set) Load indication accuracy: 0.01KN Displacement measurement: computer acquisition (0.001mm). Loading method: electro-hydraulic. Control loading mode: microcomputer control and manual stepless speed regulation double control system. Working voltage: 380V / 220V Configuration: with Lenovo brand computers, 17-inch LCD monitors, HP brand color printers Machine weight: 1500Kg Dimensions: 1120x800x1735mm
