Description

Technical Field

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

[0002] Concrete is an artificial stone material made of cementitious materials (such as cement), aggregates (such as sand, stone, etc.), water, and admixtures and additives added as needed, mixed in a certain proportion, and then uniformly mixed, compacted, and hardened. It is widely used in engineering fields such as construction, transportation, and water conservancy, and is the most widely used and largest-volume building material in civil engineering.

[0003] The basic principle of concrete compression test is to apply pressure to the concrete specimen, measure its strain and stress changes during the stress process, and thus calculate the compressive strength of the concrete and the stress-strain relationship.

[0004] Nowadays, concrete test blocks are subjected to strength and compression tests. During the test, the concrete test blocks will be compressed into many small gravels under the action of pressure. When the test is completed, these small gravels fall into various corners of the equipment and need to be cleaned up manually, which is time-consuming, labor-intensive and extremely inconvenient to clean up. Utility Model Content

[0005] The embodiment of the utility model provides a testing device for the compressive performance of concrete to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical scheme: it includes a test box, a hydraulic press is provided above the test box, the output end of the hydraulic press extends to the interior of the test box and is fixedly connected to an extrusion plate, a placement table is provided on the bottom wall inside the test box, the placement table is hinged with an internal hollow pressure box through a rotating shaft, a first opening is provided on the side of the pressure box close to the box door, a second opening is provided on the upper part of the pressure box for the extrusion plate to enter and exit, and the pressure box is provided with a driving component for driving the pressure box to tilt at a certain angle around the rotating shaft.

[0007] Furthermore, the driving assembly includes a connecting rod fixedly connected to the side wall of the pressure box, an arc groove opened on the outer wall of the box, a telescopic rod located on the outer wall of the test box, and a push plate connected to the output end of the telescopic rod, and the connecting rod extends through the arc groove to the outside of the test box.

[0008] Furthermore, the front side of the test box is provided with an openable and closable door.

[0009] Furthermore, the other end of the connecting rod is rotatably connected to a rotating wheel.

[0010] Furthermore, a cleaning box is provided outside the test box, and the cleaning box is located at the front side of the test box.

[0011] Furthermore, a test line mark is provided at the lower part of the pressure box.

[0012] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0013] In the utility model, the hydraulic press is started to drive the extrusion plate to press down, and the extrusion plate passes through the second opening to extrude the tested concrete. After the concrete is crushed, the extrusion plate rises, and then the telescopic rod is extended to drive the push plate to push the connecting rod upward. The connecting rod moves in the arc groove to drive the pressure box to tilt at a certain angle around the rotating shaft. When tilted at a certain angle, the crushed stones will slide out through the first opening due to their own weight, so that the concrete crushed stones can be cleaned conveniently.
