Concrete slump detection device

Abstract

The invention relates to a concrete slump detection device, and the device comprises a supporting base; a supporting bottom plate is arranged on the upper surface of the supporting base, a detection cylinder is arranged on the upper surface of the supporting bottom plate, a supporting cross beam A is connected to the outer side face of the detection cylinder, the outer end of the supporting cross beam A is connected with a lifting mechanism A, and a box body is fixed to the upper surface of the supporting cross beam A; a push plate is arranged in the box body, the push plate is connected with the inner side face of the box body in an up-down sliding mode, and the lower surface of the push plate is connected with the supporting cross beam A through a lifting mechanism B. The side face of the box body is provided with a discharging port facing the direction of the detection cylinder, and the discharging port is located above the feeding port at the top end of the detection cylinder. A material pressing mechanism is arranged above the detection cylinder, the top end of the material pressing mechanism is connected to a supporting cross beam B through a telescopic mechanism A, and the two ends of the supporting cross beam B are connected with the supporting base through lifting mechanisms C respectively. The device has the advantages of being good in concrete compaction effect and high in detection structure accuracy.

Description

technical field [0001] The invention belongs to the technical field of concrete processing equipment, and in particular relates to a concrete slump detection device. Background technique [0002] The existing slump test method is usually: use a trumpet-shaped slump barrel with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and fill it three times, and use a tamping hammer along the barrel after each filling. The wall is evenly hit from the outside to the inside. After tamping, smoothing, and then pulling up the bucket, the concrete will slump due to its own weight. The height of the highest point of the concrete after the bucket is subtracted from the bucket height (300mm) is called the slump; In this process, operations such as tamping, smoothing, and pulling up the bucket are usually performed manually by workers, which is time-consuming and laborious, and the degree of compaction of the concrete is not easy to control.

[0002] The existing slump test method is usually: use a trumpet-shaped slump barrel with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and fill it three times, and use a tamping hammer along the barrel after each filling. The wall is evenly hit from the outside to the inside. After tamping, smoothing, and then pulling up the bucket, the concrete will slump due to its own weight. The height of the highest point of the concrete after the bucket is subtracted from the bucket height (300mm) is called the slump; In this process, operations such as tamping, smoothing, and pulling up the bucket are usually performed manually by workers, which is time-consuming and laborious, and the degree of compaction of the concrete is not easy to control. In addition, it is easy to touch the concrete in the process of pulling up the bucket, which will cause affect the accuracy of the test results; therefore, it is very necessary to provide a concrete slump detection device that saves time and effort, has a good concrete compaction effect, and has high accuracy in detecting structures.
