Abstract

The invention discloses a numerical display proving ring coefficient calibration device. The device comprises a counterforce frame, a force-measuring device, a proving ring bearing table, a lifting device and a power device, wherein the force-measuring device comprises an S-shaped force-measuring sensor and a numerical displayer; the counterforce frame is a framework formed by a crossbeam and columns supporting the two ends of the crossbeam, and the columns are connected with the lifting device; the S-shaped force-measuring sensor is arranged below the crossbeam and is electrically connected with the numerical displayer; the proving ring bearing table is arranged at the upper end of the lifting device and corresponds to the bottom of the S-shaped force-measuring sensor; and the power device is arranged in the lifting device. The numerical display proving ring coefficient calibration device has the advantages that the device is simple in structure, safe and convenient to use, high in calibration result precision and easy to carry, the defect of a traditional proving ring coefficient calibration method is overcome, and a novel device and method are provided for proving ring coefficient calibration. The device is suitable for calibration of proving ring coefficients of direct shear apparatus, unconfined compression apparatus, vane-shear apparatus and other apparatus and serves engineering detection.

Description

technical field [0001] The invention relates to the technical field of testing soil mechanical properties, in particular to a device for calibrating the force ring coefficient with a digital display, through which the force ring coefficient can be quickly and accurately measured, providing a powerful tool for testing the shear and compressive strength of soil Assure. Background technique [0002] In the test of soil mechanical properties, it is often necessary to provide the shear strength and compressive strength index of the soil. The instruments used to test the shear and compressive strength indexes mainly include direct shear instrument, unconfined compression instrument and cross plate shear Instruments, etc., and the most important part of these instruments is the measuring ring. At present, the traditional method of measuring the force ring coefficient is the scale method, which is inconvenient to operate, has a large human influence factor, and has potential safety...
