Description

Technical Field

[0001] The utility model belongs to the field of slump detection devices, and in particular relates to a slump detection device for engineering detection. Background Art

[0002] The slump detection device is an engineering testing equipment used to test the workability of concrete mixtures. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. Workability refers to whether the concrete is easy to construct and operate and is uniformly dense. It is a very comprehensive performance that includes fluidity, cohesion and water retention. The main factors affecting workability are water consumption, water-cement ratio, sand ratio, as well as cement types, aggregate conditions, time and temperature, admixtures and other aspects. The slump test method is: fill the slump bucket with concrete three times, and tamp the concrete with a tamping rod after each filling. After filling, smooth it, and then pull up the bucket. The concrete collapses due to its own weight. The slump is obtained by subtracting the height of the highest point of the concrete after collapse from the height of the bucket.

[0003] In traditional slump detection, after the slump cone is poured into concrete and compacted, the slump cone is pulled out manually. During the pulling out process, the worker may fail to detect the concrete due to improper operation or scratching the concrete. In addition, when measuring the height of the concrete after collapse, the worker needs to lie on the ground to measure it because the concrete height is low. This is not only inconvenient to measure, but the data error of manual measurement is also large. Therefore, a slump detection device for engineering detection is proposed to address the above problems. Utility Model Content

By setting a storage box, a slump cone, a fixed rod, a driving cylinder, a rotating motor, a screw rod, a bearing, a threaded cylinder, a fixed plate, a fixed ring, a through groove and a fixed groove, the slump cone is lifted instead of manually, which can prevent the slump cone from shaking when it moves upward and cause detection failure. The device is powered on before use. When an experiment is required, the slump cone is first installed, and the slump cone is inserted from bottom to top into the inner side of the fixed ring at one end of the fixed plate.

At this time, the threaded cylinder slides inside the driving cylinder and drives the fixed plate, the fixed ring and the slump cone to move downward until the bottom end of the slump cone is tightly fitted with the inside of the storage box. Then, concrete is poured into the inside of the slump cone. After the concrete is compacted, the rotating motor is started, and the output end of the rotating motor drives the screw rod to rotate inside the bearing. At this time, the threaded cylinder slides inside the driving cylinder and drives the fixed plate, the fixed ring and the slump cone to move upward, and the lifting of the slump cone is completed.
