Multifunctional high-accuracy hardened concrete test-piece treatment machine

Abstract

The invention discloses a multifunctional high-accuracy hardened concrete test-piece treatment machine. The multifunctional and high-accuracy hardened concrete test-piece treatment machine comprises a rack, a motor, a speed changing box, a rotating shaft, a drilling bit, a test-piece clamping device, a test-piece horizontal movement mechanism and a vertical lifting mechanism, wherein the rotating shaft is driven by the motor and the speed changing box; the drilling bit is fixed at the free end of the rotating shaft; the vertical lifting mechanism acts on the rotating shaft to enable the rotating shaft to rise and fall in the vertical direction; a test piece is fixed on the test-piece horizontal mvoement mechanism by the test-piece clamping device; the test-piece horizontal movement mechanism can move along the forward-rearward-leftward-rightward directions on the horizontal plane. The multifunctional high-accuracy hardened concrete test-piece treatment machine disclosed by the invention has the advantages that the treatment problems of grinding, core drilling, hole drilling, end-surface abrading and the like before the test are solved; the multifunctional high-accuracy hardened concrete test-piece treatment machine integrates multiple concrete test piece treatment functions, is high in working efficiency and high in processing accuracy, and is used for carrying out various performance tests on the hardened concrete test piece.

Description

technical field [0001] The invention relates to a processing device for hardened concrete specimens, in particular to a multifunctional device integrating powder grinding, core drilling, hole forming and the like. Background technique [0002] Concrete is the most important building material in contemporary times. It was initially considered as an indestructible material, but as time goes by, due to the intrusion of external corrosive media or chemical reactions in concrete, the durability of concrete has been increasingly questioned. focus on. The test of hardened concrete has also gradually developed into a variety of test methods such as electrochemical properties and chemical analysis from the past, which only focused on the basic physical properties of concrete itself. However, different tests of hardened concrete have different concrete specimen processing requirements. [0003] The durability of concrete structures in marine engineering is the most prominent.

AI Technical Summary

Problems solved by technology

The device can grind concrete sample powder, but its disc-shaped grinding piece has a large contact area with the sample, and the frictional resistance is large. It cannot flexibly grind any part of the sample at any depth. The function is relatively single, and it cannot meet the test requirements. Diversified sample processing requirements in the chamber; the area of ​​the grinding piece is relatively large, and the contact grinding surface with the sample is easy to be uneven, resulting in uneven rotation, resulting in different depths of the grinding section, and it is difficult to achieve high-precision control of the depth, which affects the accuracy of the test; The rotating mechanism and the sample fixture platform are designed separately, the stability is not good, and the vertical accuracy and layering depth control accuracy are difficult to control; when the feed rate of the grinding disc is not controlled during the grinding process, it is easy to cause excessive grinding and affect the quality of the sample; The disc-shaped grinding sheet makes it difficult for the ground powder sample to move out of the grinding surface quickly, thereby reducing the grinding efficiency
