Concrete slump detection device capable of regulating compaction plate

Abstract

The invention discloses a concrete slump detection device capable of regulating a compaction plate. The device structurally comprises a bottom disk, a first guide rail, a movement frame, a slump cone,an importation hole, a rammer, an expansion link, a stay bar, a motor, a second guide rail and a measurement bar, wherein two sides of the bottom disk are independently vertically connected with thefirst guide rail and the second guide rail; the slump cone is arranged in the middle of the bottom disk; the top of the slump cone is provided with the importation hole; the slump cone and the movement frame are connected; the movement frame is installed on the first guide rail; the rammer is arranged above the slump cone and is connected with the stay bar through the expansion link; the stay baris installed on the second guide rail; the measurement bar is installed below the stay bar; and the motor is installed on the stay bar and is in transmission connection with the expansion link througha belt. The device has the beneficial effects that the connection position of the compaction plate and the expansion link is regulated to regulate a distance between the compaction plate and the inner wall of the slump cone, and therefore, concrete at different heights in the slump cone can be subjected to even compaction in an omnibearing way.

Description

technical field [0001] The invention relates to the field of concrete detection, in particular to a concrete slump detection device with an adjustable compacting plate. Background technique [0002] The basic test method of concrete slump is to use a trumpet-shaped slump bucket with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm. To prevent the concrete from affecting the measurement data, the concrete slumps due to its own weight, and the height of the highest point of the concrete after the collapse is subtracted from the height of the bucket (300mm), which is called the slump. [0003] The current concrete slump detection device pours the retarded concrete into the slump cylinder three times during work, and three times of compaction are required. Since the top of the slump cylinder is small and the bottom is large, the extended ram cannot Part of the compaction, compaction is not sufficient, prone to deviations in the measurement.
