Unconfined compressive strength part and demolding and strength measuring integrated testing machine

Abstract

The invention discloses an unconfined compressive strength part and a demolding and strength measuring integrated testing machine which can be used for finishing high-efficiency and high-quality test detection operation. The testing machine comprises fixing nuts, an upper bearing plate, upright posts, clamping parts, jackscrews, a frame, a lower bearing plate, a motor, a lifting jack, rails, a data line, a pressure sensor, a hydraulic pipe, a test mold, an annular stirrup, an adjusting screw rod, vehicle panel fixing fasteners, a round plate with an annular groove, a sliding trolley panel, wheels, axles, clamping plates and clamping plate slideways. According to the design of the double upright posts, the overall weight is reduced; bottom feet are designed on the lower bearing plate, and thus stress deformation of the lower bearing plate is avoided; due to the design of the clamping parts with a jackscrews and the annular stirrup added to the test mold, a novel mode of simple and feasible demolding is created. According to the invention, the various parts can be convenient to detach and assemble, the equipment performance is stable, the operation is simple, labor force is saved, the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of highway engineering testing and detection, in particular to an integrated testing machine for unconfined compressive strength parts, demoulding and strength measurement. Background technique [0002] The equipment used in the production of the current inorganic binder stabilized material test piece is the reaction force frame and the jack, and the demoulding equipment is the jack and the demoulding frame, that is, the workpiece and the demoulding working device are divided into two parts. The whole operation is realized manually, which has high labor intensity, low work efficiency, many human factors, and the test data is prone to variation. [0003] China Hangzhou Sansi Instrument Factory has manufactured the model YSTM-100 hydraulic part demoulding integrated machine, forming and demoulding can be completed at one time, minus the unfavorable factors of the old-fashioned method such as repeated handling ...

Problems solved by technology

But in the construction stage, due to the maintenance of the test piece, the construction period will be affected, especially in the case of a tight construction period, the device cannot meet the detection of multi-measuring point samples at the same time; public (announcement) number: CN202886204U, disclosed An axial deformation press, equipped with a measuring device capable of reading the deformation in the vertical direction, can accurately measure the infinity of the asphalt mixture specimen when the axial deformation reaches a certain value at a certain temperature point. Confined compressive strength value

However, the device has a single function and does not have the three functions of mold making, testing, and demoulding. When testing the sample, it cannot effectively control the damage that may occur when the sample is made and placed on the machine, which affects the accuracy of the experimental test; Publication (announcement) number: CN202057534U discloses a test piece forming auxiliary device for unconfined compressive strength test. The device uses the pressing edge on the cover plate to easily adjust the angle when the test piece is formed so that the cover plate and the lower part of the test mold The pad is pressed vertically into the test mold, and the cover plate can be removed in advance when demoulding, which is convenient for demoulding and not easy to damage the test piece; the weight of the cover plate can be reduced by excavating the groove

However, this device is only an auxiliary device and cannot completely replace the function of the unconfined compression machine. It has not improved the detection ability of the experimental machine itself, and has not considered the accuracy and damage reduction.
