Concrete automatic sampling and test block forming control method

Abstract

The invention belongs to the technical field of concrete making, and particularly relates to a concrete automatic sampling and test block forming control method. The method comprises the steps that first, after a control device receives a sampling forming instruction, the control device controls an introduction belt to rotate so as to drive an empty test mold to stop rotating after arriving at theposition in front of an air cylinder; second, the air cylinder of the control device pushes the empty test mold into a vibration platform from the introduction belt, and enables the empty test mold to be located below a sampling port; third, the control device controls the sampling port to be opened so that concrete in a storage hopper enters the empty test mold below, and the vibration platformis started up to vibrate at the same time; fourth, after the empty test mold is filled with concrete, the sampling port is controlled to be closed; fifth, the vibration platform is controlled to stopvibrating, a test mold push-out air cylinder pushes the formed test mold out of the vibration platform at the same time and pushes the test mold into an exit belt, the exit belt rotates forwards to take the test mold away, and at the same time, the test mold push-out air cylinder withdraws to be in the initial state; and sixth, the steps above are executed again according to control instructions.With the concrete automatic sampling and test block forming control method, concrete can be automatically sampled, automatically formed, automatically vibrated and automatically transferred.

Description

technical field [0001] The invention belongs to the technical field of concrete manufacture, and in particular relates to a concrete automatic sampling and test block forming control method. Background technique [0002] In order to test the performance of the concrete produced by the concrete manufacturer, it is often necessary to sample the concrete, and make the sampled concrete into a standard test block through a test mold, then maintain the test block, and finally perform a performance test on the test block to obtain the corresponding The performance parameters, these parameters are important indicators to measure the quality of concrete components, [0003] The sampling and test block forming process is cumbersome. Specifically, the sampling of concrete is usually taken from the concrete tank truck. When the concrete tank truck receives a certain amount of concrete from the storage hopper of the mixing station and is ready to leave the factory, the test personnel ins...

[0003] The sampling and test block forming process is cumbersome. Specifically, the sampling of concrete is usually taken from the concrete tank truck. When the concrete tank truck receives a certain amount of concrete from the storage hopper of the mixing station and is ready to leave the factory, the test personnel instruct the concrete tank truck to drive to the factory. Designate the location, and use a box-type trolley or a receiving bucket to place it under the concrete tank truck, and instruct the driver of the concrete tank truck to operate the discharge. Usually, more discharge is required so that there are enough concrete samples for the experiment, and then the experiment will be tested Personnel need to transfer the concrete samples in the box-type trolley or receiving bucket to the laboratory, put the concrete samples into the test mold, then place them on the vibrating table to vibrate and smooth them, and then write the concrete number on paper, and paste the paper on the test block, and then move the test mold to the curing room for curing, and then remove the mold after curing; in addition, because more concrete was taken during sampling, the follow-up treatment of these concrete is also more troublesome. A good treatment method is to transfer the concrete wastewater washed on the vibrating table to the sedimentation tank in the factory for recycling treatment. It can be seen that different manual interventions are required in the whole process, and it needs to be collected at sampling points, laboratories and sewage treatment tanks. Running back and forth is not only a waste of materials and a huge amount of labor, but also prone to mistakes due to negligence, causing potential losses to the construction project
