Strength detection device of concrete penetration resistance meter

Abstract

The invention relates to the technical field of concrete performance detection, and discloses a strength detection device of a concrete penetration resistance meter. The strength detection device comprises a base, wherein the left side of the top of the base is bolted with a supporting column, the top of the supporting column is bolted with a display screen, the right side of the supporting column is bolted with a transverse plate, and the left side of the top of the transverse plate is hinged with a pressing rod. An experiment sample is placed in a sample barrel, a pressing rod is pressed downwards so as to enable a worker to detect the sample in the sample barrel, then a screw is rotated, the position of an adjusting seat is moved rightwards, a small bevel gear is rotated through a rotating shaft, then a large bevel gear is driven to achieve rotation of a rotating seat, different positions of the sample can be detected, the motor rotates, and a belt is used for driving the rotating wheel to rotate, so that the sample barrel can rotate, the accuracy of a detection result can be ensured, detection errors are reduced, workers do not need to manually process tested samples any more, the working difficulty of the workers is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of concrete performance detection, in particular to a strength detection device of a concrete penetration resistance meter. Background technique [0002] The penetration resistance meter is an instrument for measuring the setting time of concrete. The existing penetration resistance meter moves the penetrating needle vertically downward through the handle. When the penetrating needle penetrates into the concrete mortar in the sample mold, the mortar It 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. The corresponding penetration resistance is measured through different test points, and the initial setting and intermediate setting of the concrete are obtained. Detecting the strength of concrete under the three states of final setting and final setting i...
