An integrated testing machine for unconfined compressive strength parts, demoulding and strength measurement

Abstract

The invention discloses an integrated testing machine for unconfined compressive strength parts, demoulding and strength measurement, which can complete the test and detection work with high efficiency and high quality. The testing machine includes: fixed nuts, upper bearing plate, column, clips, top wire, frame, lower bearing plate, motor, jack, track, data line, pressure sensor, hydraulic pipe, test mold, ring stirrup, adjusting screw , car panel fixing buckle, circular plate with ring groove, sliding car panel, wheel, axle, card board and card board slideway. The present invention is designed with double columns, which reduces the weight of the whole machine; the foot of the lower bearing plate is designed to prevent the deformation of the lower bearing plate; Simple and easy demoulding new mode. Each part of the invention can be disassembled and assembled conveniently, the equipment has stable performance, is easy to operate, saves labor, reduces labor intensity and improves work efficiency.

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, because the test pieces need to be maintained, the construction period will be affected, especially in the tight situation of the construction period, the device can not meet the detection of multi-measuring point samples simultaneously; 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 kind of test piece forming auxiliary device for unconfined compressive strength test, this device utilizes 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.
