Description

Technical Field

[0001] This utility model applies to the field of concrete testing technology, and in particular relates to a concrete hardness testing device. Background Technology

[0002] Currently, concrete refers to artificial stone made by mixing cement as the main binder with water, sand, and gravel, and, when necessary, chemical admixtures and mineral admixtures, in appropriate proportions, and then uniformly mixing, compacting, molding, and curing. Concrete hardness is an important indicator for measuring the strength and quality of concrete. By measuring the hardness of concrete, we can determine its strength, durability, compressive strength, and other aspects. Generally, the higher the hardness of concrete, the greater its strength, the stronger its compressive strength, and the stronger its resistance to external forces. This is crucial for ensuring the safety and stability of concrete in practical applications. Therefore, before using concrete, samples are tested for hardness.

[0003] However, current methods for testing the hardness of concrete samples involve continuously increasing pressure applied from the top side until the sample breaks. This results in a large accumulation of concrete fragments on the testing platform, requiring manual cleaning to prevent them from interfering with subsequent hardness testing. Manual cleaning is insufficient to completely remove all the debris, impacting the efficiency of the hardness test. Therefore, we propose a concrete hardness testing device. Utility Model Content

[0004] The main purpose of this invention is to provide a concrete hardness testing device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A concrete hardness testing device includes a support platform, on which support columns are vertically fixedly installed on all four sides of the top of the support platform, a connecting plate is fixedly installed between the tops of the support columns, and a hydraulic push cylinder is fixedly installed on the outer side of the top of the connecting plate.

[0007] A fixed plate is fixedly installed on the top side of the support platform, and protective baffles are fixedly installed horizontally on both sides of the top of the support platform. The side of the fixed plate and the side of the protective baffle are fixedly connected. A movable plate is movably provided on the side of the fixed plate, and a guide baffle is rotatably provided at both ends of the side of the movable plate.

[0008] The torsion mechanism is arranged at both ends of the side edge of the movable plate and is connected with the material guide baffle in transmission.

[0009] Through the mutual cooperation of the torsion mechanism and the adsorption limiting mechanism, the movable plate and the material guide baffle can push and clean the concrete blocks accumulated on the bearing table, avoid the random rolling of the concrete blocks, reduce the labor consumption of the operator, and facilitate the subsequent normal use of the overall detection mechanism.

[0010] As an optional solution of the technical scheme of the application, the torsion mechanism comprises a push torsion spring, the four corners of the side edge of the movable plate are fixedly provided with mounting plates, every two groups of the mounting plates are vertically rotatably connected with rotating rods through bearings, each material guide baffle is fixedly sleeved on the outer wall of the rotating rod, and the bottom of the material guide baffle is movably attached to the top surface of the bearing table.

[0011] Through the above technical scheme, the rotating rod is connected with the transmission rod and the material guide baffle in transmission, so that the driving force required for the rotation of the material guide baffle can be provided under the torsion of the push torsion spring, thereby ensuring that the material guide baffle can gather and prevent the scattering of the blocks pushed by the movable plate.

[0012] As an optional solution of the technical scheme of the application, the adsorption limiting mechanism comprises a fixed magnet, and the two ends of the side edge of the movable plate are provided with mounting grooves, and each mounting groove is fixedly provided with a fixed magnet inside.

[0013] Through the above technical scheme, the adsorption structure of the fixed magnet can adsorb and limit the material guide baffle, so as to avoid the random rotation of the material guide baffle and affect the placement of the concrete sample.

[0014] As an optional solution of the technical scheme of the application, the bearing table is fixedly provided with a material discharging guide plate, the top of the material discharging guide plate is fixedly provided with fixed baffle plates on both sides, the two ends of the side edge of the fixed plate are fixedly provided with electric push rods, and the outer side of the electric push rod is fixedly connected with the outer side of the movable plate.

[0015] Through the above technical scheme, the driving action of the electric push rod can provide the movable plate and the material guide baffle with the power required for horizontal movement, so that the movable plate and the material guide baffle can push and clean the debris accumulated on the surface of the bearing table.

[0016] Compared with the prior art, the concrete hardness detection device has the following beneficial effects:

[0017] 1.The concrete hardness detection device of the technical scheme of the present application, by setting a movable plate on the top of the bearing table, and setting a rotatable material guide baffle on the side of the movable plate through a rotating rod, and connecting the driving torsional spring and the rotating rod through a transmission rod, so that after the hardness detection of the concrete sample is completed, the transmission rod and the rotating rod can be provided with synchronous rotation force under the torsional transmission of the driving torsional spring, thereby driving the material guide baffle to synchronously rotate and open on the side of the movable plate, and then the movable plate can be rotated and attached to the outside of the protective baffle, while the movable plate and the material guide baffle can clean the concrete chunks accumulated on the bearing table by pushing the material, avoiding the random rolling of the concrete chunks affecting the cleaning of the concrete chunks, reducing the labor consumption required by the operator for cleaning, and facilitating the subsequent normal use of the overall detection mechanism.

[0018] 2.The concrete hardness detection device of the technical scheme of the present application, by setting a fixed magnet on the side of the movable plate, and combining the fixed magnet with the adsorption and fixation of the material guide baffle, so that when the surface of the bearing table does not need to be cleaned, the material guide baffle can be adsorbed and fixed on the front side of the movable plate so that it will not be randomly rotated and opened on the surface of the bearing table, thereby avoiding the influence of the material guide baffle on the placement of the concrete sample on the surface of the bearing table, and ensuring the normal hardness detection of the concrete sample.
