Description

Technical Field

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

[0002] Concrete refers to the general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the concrete mentioned refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as the aggregate, and water (which may contain admixtures and additives) in a certain proportion and is obtained by stirring. It is widely used in civil engineering.

[0003] Concrete has become an essential product in modern life and is used in various occasions such as building houses and roads.

[0004] Since concrete is generally made by mixing multiple materials, different material ratios will also affect the performance of the formed concrete. Some have higher strength, while some are smoother.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] In the embodiments of the present application, please refer to Figure 1 and 2 , a concrete strength detector includes a base 10, a cushion block 11 is arranged on the top of the base 10, a support plate 20 is fixed on the top of the base 10 and located at the back of the cushion block 11, a top seat 30 is fixed on the top of the support plate 20, a hydraulic cylinder 40 is fixed on the top of the top seat 30. The hydraulic cylinder 40 can be an existing one and is connected and controlled in an existing manner. The output end of the hydraulic cylinder 40 is fixed with a movable column 50. An activity groove 31 is opened inside the top seat 30, the movable column 50 is slidably arranged inside the activity groove 31, one ends of a plurality of connecting rods 60 are fixedly connected to the movable column 50 in a ring shape. A plurality of guide grooves 32 are opened inside the top seat 30, the guide grooves 32 communicate with the activity groove 31, the connecting rods 60 are slidably arranged inside the guide grooves 32, the other ends of the connecting rods 60 are connected with a protective cover 70 covering the outside of the top seat 30, and an impact block 90 is threadedly connected to the bottom of the movable column 50 through a threaded column 91;

[0042] The shape of the protective cover 70 can be as shown in Figure 2 ;

[0043] During use, place the solidified concrete block to be detected on the cushion block 11, then start the hydraulic cylinder 40 to drive the movable column 50 and the impact block 90 to move downward. The impact block 90 can then impact the concrete block to be detected, and the strength of the concrete can be judged according to the degree of damage after the impact. The operation is simple. During this process, the movable column 50 will drive the connecting rod 60 and the protective cover 70 to move downward. Thus, during the impact, the concrete fragments splashing out will be blocked by the protective cover 70, preventing them from splashing out, and the safety is higher;

[0044] The impact block 90 has various sizes. During use, select different-sized impact blocks 90 according to needs, which can adapt to different impact test requirements, have better adaptability, and more accurate test results.

[0045] In a further embodiment, please refer to Figure 1 and 3 , a cushion seat 80 located below the protective cover 70 is fixed to the top of the cushion block 11. Specifically, the cushion seat 80 includes a fixed cushion 81 fixed to the top of the cushion block 11. A fence 82 and a soft cushion 83 are fixed to the top of the fixed cushion 81. The soft cushion 83 is located inside the fence 82 and directly below the protective cover 70. After the protective cover 70 descends and contacts the soft cushion 83, the fence 82 is located outside the protective cover 70. During the downward movement of the protective cover 70, its bottom will rest on the soft cushion 83.

[0046] In a further embodiment, please refer to Figure 1 , 2 and 4. The connection structure between the connecting rod 60 and the protective cover 70 includes a fixing plate 61 fixedly connected to the connecting rod 60. A plurality of sliding grooves 62 are formed inside the protective cover 70. The fixing plate 61 is fixedly connected with a sliding rail 63 slidably arranged inside the sliding groove 62. A plurality of rollers 64 are rotatably connected to the sliding rail 63. A support rod is fixedly connected between the connecting rod 60 and the fixing plate 61 obliquely. Usually, under the action of the gravity of the protective cover 70, the sliding rail 63 is located at the uppermost end of the sliding groove 62. Moving the protective cover 70 upward can slide the sliding rail 63 out of the sliding groove 62, and finally remove the protective cover 70 from above. Conversely, it can be installed;

[0047] During the detection process, when the protective cover 70 touches the soft cushion 83 and stops moving, the connecting rod 60, the fixing plate 61, and the sliding rail 63 can still move downward normally without being affected. Therefore, it can adapt to different concretes.
