A high-precision point load tester with automatic detection function

Abstract

The invention relates to a high precision point load tester with an automatic detection function. The high precision point load tester comprises a support mechanism, a force measuring mechanism, a driving mechanism and a loading mechanism, wherein the force measuring mechanism comprises a jack, a pushing block, a pressure sensor and a programmable logic controller (PLC); the driving mechanism comprises a motor, a half gear, a driving frame, a strip gear and a drive block; a measuring assembly comprises a connecting block, a limit lever, a lifting block, a bolt, a spacing ring, a spring, an upper contact block, a lower contact block and an extrusion block. The high precision point load tester with the automatic detection function is ingenious in design and high in feasibility; when the high precision point load tester needs to be used for measuring, the jack is driven to automatically push the pushing block up by the driving mechanism, so that a point load can be tested; the depth, at which a loading head enters a rock, can be detected by the measuring assembly, so that the high precision point load tester can detect point load indexes at different depths, and the point load indexes of rocks can be further accurately and comprehensively tested.

Description

technical field [0001] The invention relates to the field of petroleum exploration, in particular to a high-precision point load tester with automatic detection function. Background technique [0002] A point load test is an easy method of testing the tensile strength of rock, concrete, or other natural building materials under a point load, a point load test is an instrument that performs a point load. [0003] Nowadays, the point load tester used displays the length of the tested rock specimen and the maximum load of the rock specimen through the digital display tube, and then calculates the point load strength index of the rock specimen, but the calculation process still requires manual operation. And it brings disadvantages such as inconvenient calculation and low efficiency, and it is difficult to measure the depth of the loading head entering the rock during measurement, which requires manual measurement, which has low accuracy and low efficiency.
