Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0022] as attached Figure 1~6 As shown, the parts are cleaned with kerosene during assembly, and the mating surface is oiled after drying. The unprocessed surface of each part should be cleaned, the burrs should be removed, the anti-rust paint should be dipped, and multi-layer raw tape should be wound on the sealing port to strictly ensure the hydraulic cylinder And the tightness of the connection between the hydraulic cylinder and the hose; figure 1 There are two sets of identical small-range detection subsystems. It is assumed that system A is on the left and system B is on the right. Both system A and system B include small-range high-precision displacement sensors, plunger hydraulic cylinder output shafts, Hydraulic cylinder, plunger type hydraulic cylinder fixing plate, connecting hose, piston type hydraulic ...

Abstract

The invention belongs to the technical field of mechanical engineering testing, and relates to a hydrostatic transmission type large-range displacement bidirectional detection device. It includes two identical small-scale detection subsystems: A system and B system; the device uses high-precision small displacement sensors and servo motors to ensure measurement and positioning accuracy. The hydrostatic transmission mode is adopted, and the movement is smooth to ensure that there is no additional vibration interference during the detection process. The device is smart in structure, reasonable in layout, strong in adaptability, long in service life, and high in measurement accuracy, and solves the problem of high-precision two-way measurement in a large range and full range, and has good economy and popularization value.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering testing, and relates to a triaxial test of soil mechanics, in particular to a large-scale high-precision displacement bidirectional detection device. Background technique [0002] To measure the strength and deformation of soils a triaxial tester is often used, which is widely used and can be used to measure a variety of parameters including shear strength properties, consolidation characteristics and soil permeability. Among them, the change of the axial displacement of the sample under a certain stress is a very important measurement parameter, and the measurement accuracy of the axial displacement determines the success or failure of the triaxial test. For small and medium-sized triaxial testers, the variation range of the axial displacement of the sample is usually less than 150mm, and the existing linear displacement sensors (such as: inductive, resistive, magnetic ring displac...
