Concrete penetration resistance meter

Abstract

The invention relates to a concrete penetration resistance meter. The meter comprises a horizontally-arranged base, a mold testing barrel is vertically arranged on the upper side of the base, a stand column is vertically and fixedly connected to one side of the base, a supporting arm is fixedly connected to the side, close to the base, of the stand column, and a penetration column is vertically arranged at the end, away from the stand column, of the supporting arm. A pressing rod with the middle hinged to the supporting arm is arranged on the upper side of the supporting arm, one end of the pressing rod can drive the penetration column to vertically move, a sliding disc is slidably connected to the base, a fixed rack is fixedly connected to the lower side of the sliding disc, a driving shaft is rotationally connected to the lower side of the base, and a gear is fixedly connected to the driving shaft; and one end of the driving shaft extends to the lower side of the stand column and is fixedly connected with a ratchet wheel, a movable rod is vertically arranged in the stand column, the pressing rod can drive the movable rod to vertically move, and a ratchet bar is vertically arranged at the lower end of the movable rod. The meter has the advantages that the position of the test mold is convenient to adjust, the labor intensity of workers is reduced, and the test efficiency is improved.

Description

technical field [0001] The application relates to the field of concrete detection equipment, in particular to a concrete penetration resistance meter. Background technique [0002] The concrete penetration resistance meter is an instrument for measuring the setting time of concrete. It is suitable for measuring the setting time of various cements, admixtures and concrete mixtures with different concrete ratios. The existing concrete penetration resistance meter includes a testing device, the testing device includes a penetrating needle, and the penetrating needle moves vertically downward by pressing the testing device with a handle. The glue produces resistance to the penetrating needle, and this force is displayed through the display device. With the increase of time, the penetration resistance of the concrete mortar increases correspondingly, and the corresponding pouring resistance is measured through different measuring points to obtain the setting time data of the con...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the concrete penetration resistance meter needs to test multiple test points, and the arithmetic mean value is taken as the penetration resistance value, and multiple penetration points in the same trial mold may easily cause overlap of penetration points , affects the accuracy of the test results, so it is necessary for the staff to move the position of the material mold according to experience to ensure multiple penetration points of the test mold. During the whole process, the material mold is continuously transported, measured, and transported, which affects the overall measurement speed, hassle
