Description

Technical Field

[0001] The utility model relates to the technical field of concrete slump detection, in particular to a concrete slump detection device. Background Art

[0002] Concrete slump refers to the degree of deformation and flow of a concrete sample under the action of a slump tower under specified conditions. It is an important indicator to measure the fluidity and plasticity of concrete, and directly affects the quality of concrete pouring and construction effect. In the prior art, when performing slump detection, a slump bucket is usually taken first, and then filled with concrete three times. After each filling, a tamping hammer is used for tamping. After tamping, the bucket is smoothed, and then the bucket is pulled out. The concrete will collapse due to its own weight. At this time, the height of the highest point of the concrete after collapse can be subtracted from the height of the bucket. In the process of slump detection, since it is necessary to perform manual tamping after each concrete filling, automatic tamping cannot be performed during the filling process, the slump detection efficiency will be reduced to a certain extent, and the workload of the operator will be increased, making the slump detection inconvenient. Therefore, a concrete slump detection device is proposed to address the above problems. Utility Model Content

[0011] 1. A concrete slump detection device, which is provided with a reciprocating screw rod, a tamping rod, a chain, a large sprocket, a turntable and a slump barrel. When the device is used to detect the slump, a double-axis motor is started by a controller when concrete is filled into the slump barrel. At this time, the small sprocket is driven by the double-axis motor to engage the chain, and the slump barrel is further driven to rotate by the turntable in the process of engaging the large sprocket.

At this time, the threaded shaft is rotated to be spirally connected with the inner rod, so that the sleeve rod is continuously sleeved on the outside of the inner rod, so that the sleeve rod drives the tamping rod to move away from the top of the slump cylinder, thereby facilitating the subsequent pulling out of the slump cylinder for slump detection operation.

[0022] Example 3

[0023] like Figure 1-2 As shown, in order to solve the problem of inconvenience in positioning the collapse tube 8, the left and right sides of the top of the turntable 7 are fixedly connected with fixed blocks 9, and the top of the outer side of the fixed block 9 is spirally connected with a bolt 10, one end of the bolt 10 is fixedly connected with a limit shaft 11, and the limit shaft 11 is slidably connected to the collapse tube 8.
