Embodiment Construction

[0031] The structure, operation process, test process and implementation examples of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] figure 1 Among them, the present invention mainly supports the whole structure with a frame. Connect the variable frequency motor 1, the frequency converter 6 and the worm gear reducer 2 through the coupling C1, and fix them on the bottom of the frame with nuts. B4 is the desktop in the frame, which is welded on the frame and supported by angle steel. Fix the bracket flange 21 of the main engine on the desktop B4 through the nut A1, and at the same time ensure that the lower end of the shaft 15 and the output shaft of the worm gear reducer 2 are in a straight line through the coupling C2 connect. Install the hydraulic lifting device 8 on the side wall of the frame as shown in the figure. One end of the hydraulic lifting arm 7 is fixed on the hydraulic device and the other end is fixe...

Abstract

The invention relates to a multifunctional ring shear apparatus, which is applicable to measuring shear resistance of granular materials such as soil, stones and the like and volume change of the granular materials during shear. The multifunctional ring shear apparatus mainly comprises a main unit, a hydraulic lifting system, a rotary power system, a measuring system, a frame and the like, wherein the main unit, the rotary power system, the hydraulic lifting system and the measuring system are respectively fixed onto the frame, and the main unit comprises a shaft, an upper shear box, a lower shear box, a bearing flange and the like. A ring shear box provides a horizontal shear mode, a vertical shear mode and different roughness conditions, bulk granular materials such as the soil, the stones and the like flow in the ring shear box, the shear force of sheared surfaces of the granular materials is measured during flowing, and the ring shear box can be replaced in use. The multifunctional ring shear apparatus can be used for accurately measuring volume control, vertical pressure control, shear rate control, the shear force, shear rate, the volume change, pressure and the like of action objects.

Description

technical field [0001] The invention relates to a multifunctional ring shearing instrument, which is suitable for measuring the shearing resistance of soil, stone and other granular materials and the volume change in the shearing process. Background technique [0002] In recent years, with the development of geotechnical engineering and granular mechanics, more and more attention has been paid to the ring shear device for studying the mechanical properties of granular materials mainly composed of soil and stone in the flowing state. At present, my country's research on ring shearing devices mainly relies on foreign imports.
