Description

Technical Field

[0001] The utility model relates to the technical field of concrete production and processing, in particular to a collapse detection device used for concrete production and processing. Background Art

[0002] Concrete is a general term for engineering composite materials that are made by cementing aggregates into a whole. The term concrete usually refers to cement as the cementing material, sand and stone as aggregates, mixed with water in a certain proportion, and obtained by mixing. It is also called ordinary concrete. It is widely used in civil engineering. During the production and processing of concrete, the collapse of concrete needs to be tested.

[0003] In the prior art, the utility model with application number CN202220879462.5 discloses a concrete slump detection device for a concrete mixing station. The utility model can support the limit plate through a support spring to maintain the height of the limit plate, and then maintain the stability of the measuring rod. By pressing down the scale, the limit plate can apply pressure to the support spring, and the scale can drop. The limit plate can be guided by the guide groove to avoid horizontal rotation of the limit plate, and then the first sleeve and the second sleeve can be prevented from rotating. The first sleeve and the second sleeve can respectively guide and limit the measuring rod and the diagonal support, and avoid tilting of the measuring rod during the lifting and lowering process, and ensure the measurement accuracy of the measuring rod. However, in the actual measurement process, this type of equipment also needs to measure the height of the slump cylinder, and the slump can be obtained by subtracting the height of the concrete from the height of the slump cylinder, resulting in a relatively general problem in the overall detection efficiency.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The slump detection device for concrete production and processing proposed by the present invention has the following steps: first, a support rod is placed between a sample and a slump cylinder through the setting of a detection component; at this time, a support spring pushes the first sleeve so that the detection plate is higher than the slump cylinder; then, only the second sleeve needs to be pressed down; since the elastic force of the support spring is smaller than the elastic force of the buffer spring, the support spring will contract first and stop contracting after the detection plate is fitted with the top of the slump cylinder; at this time, the buffer spring contracts, and the second sleeve will drive the scale to move downward through the telescopic rod, the screw sleeve, and the screw rod, so that the scale is fitted with the top of the concrete; at this time, the slump value can be directly observed using a pointer without the need for calculation, thereby improving the efficiency of the detection.

[0015] The collapse detection device for concrete production and processing proposed by the present invention has a positioning component. When the collapse test position is low, which makes it difficult to bend over when taking readings, the bolt can be rotated after the measurement to push the connector under the limit of the nut, so that the rubber block is in close contact with the support rod, thereby quickly locking the position of the slide sleeve 1 and the slide sleeve 2. The support rod can be lifted by the handle to pick up the detection device for reading, which makes the reading more labor-saving and accurate. In addition, when a person with shaky hands is using it, after tightening the bolt during the detection process, the screw can be rotated to fine-tune the height of the scale, thereby improving the accuracy of the detection. In addition, the slide column can reduce friction loss while limiting the scale, thereby avoiding scratches on the surface of the scale that affect observation. BRIEF DESCRIPTION OF THE DRAWINGS
