Concrete slump detection device by means of substance density difference

Abstract

The invention relates to the technical field of commercial concrete production detection, and discloses a concrete slump detection device by means of a substance density difference. A support is connected to the top of a bearing plate, a threaded rod is arranged in the support and connected with a knob, a mounting plate is connected to the front surface of the support and movably connected with anadjusting rod via a rotating shaft, a first fan-shaped gear is fixedly connected to the lower end of the adjusting rod, a pull bar movably sleeves the rotating shaft and is positioned behind the adjusting rod, and a tapered cylinder is fixedly connected to the front side of a connecting block. During work of the detection device, the bubble position is observed through a bubble horizontal device,the knob is rotated to drive the threaded rod to rotate, the bearing plate which movably sleeves the threaded rod rises and falls, and when a bubble is positioned in the middle of the bubble horizontal device, the bearing plate is in a horizontal state, and thus the bearing plate is kept horizontal during test.

Description

technical field [0001] The invention relates to the technical field of commercial concrete production detection technology, in particular to a concrete slump detection device utilizing material density difference. Background technique [0002] Commercial concrete is also called ready-mixed concrete, which refers to pre-mixed concrete mixture of qualified quality, which is sold to construction units in the form of commodities. Commercial concrete is a transformation from extensive production to intensive production. The specialization, commercialization and socialization of concrete production is an important reform in the construction of relying on technological progress to change the small production mode. [0003] Concrete plays a vital role in construction and directly affects the quality and safety of the building. Therefore, the quality of concrete is particularly important. The current concrete detection method is mainly performed manually by the staff through the coni...

[0003] Concrete plays a vital role in construction and directly affects the quality and safety of the building. Therefore, the quality of concrete is particularly important. The current concrete detection method is mainly performed manually by the staff through the conical cylinder. The device is simple, and there are certain errors depending on the detection environment, such as the problem of the flatness of the ground, which leads to a large error in the detection of the slump of the concrete. When the slump is detected, the conical cylinder needs to be lifted vertically, and manual operation is not necessary. It is easy to reach, which leads to artificial changes in the concrete structure inside the conical cylinder, which makes the detection results have greater uncertainty, and when measuring the height of the concrete stockpile, it is often measured with a tape measure, which is easy to touch during operation Concrete stockpile, resulting in its height reduction, the measured slump is too large, causing the problem of wrong assessment
