Description

Technical Field

[0001] The present application relates to the technical field of building material testing, and in particular to a concrete slump testing device. Background Art

[0002] Concrete slump is an important indicator in the concrete production process. The usual method for testing slump is to take part of the concrete after mixing, and use a slump cylinder with a stirring rod to measure it offline until it passes the test, and then continue production according to the formula.

[0003] A concrete slump test device mentioned in an existing Chinese public patent (authorization announcement number: CN216285291U) includes a slump bucket, a fixed plate is symmetrically arranged at the bottom of the slump bucket, and a test bench, the test bench is a flat cylindrical structure, the slump bucket is movably arranged in the middle of the upper surface of the test bench, and limit assemblies are symmetrically arranged on both sides of the test bench, and the limit assemblies are used to fix the slump bucket; in the utility model, handles are arranged on the side walls of the test bench for easy carrying and movement, and the slump bucket commonly used in construction sites can be adapted, and there is no need to replace the existing slump bucket, and the scope of application is wider. The slump bucket is placed in the middle, and the fixed plate at the bottom of the slump bucket is fixed by a rotatable limit rod. Since there is no obstruction on the upper surface of the test bench, the flow of concrete is avoided to be affected by obstacles, so that the test result is more accurate.

[0004] When the test device is in use, it is used for the slump test of concrete to test whether the concrete is qualified and continue the subsequent production. During the slump test, the slump bucket needs to be lifted manually to complete the test. When the slump bucket is lifted manually, it is easy for the slump bucket to move laterally due to different manual forces when lifting, which can easily affect the detection results of the slump test. During the test, it is also necessary to manually clean up the concrete that falls on the test bench and flows out of the slump bucket when the island is inserted, which is inconvenient.

Before tamping, the restriction on the tamping rod 6 can be released by screwing the bolt on the electric telescopic rod 5. The angle of the tamping rod 6 is fixed at a suitable angle, and the concrete is tamped. After the tamping is completed, the manual tamping is reduced, the labor intensity is reduced, and the test is convenient. The funnel 8 is removed, and the concrete on the upper end of the test barrel 7 is smoothed by a scraper;

[0042] When the test device is in use, start the motor 29, the motor 29 drives the screw 10 to rotate, so that the fixed block 11 moves on the screw 10, so that the fixed block 11 drives the test barrel 7 to move, and the test barrel 7 drives the fixed block 213 to move, so that the fixed block 21 slides on the guide rod 12, and the test barrel 7 is restricted, so that the test barrel 7 can move stably.
