Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a construction engineering concrete hardness detection device. Background Art

[0002] Concrete strength testing is crucial for ensuring the safety and durability of concrete structures. Common testing methods include static testing, which uses a compression tester to compress concrete specimens to determine their compressive strength. This is one of the most direct and commonly used methods, applicable to a variety of concrete structures and components.

[0003] In the prior art, when the pressure testing machine performs compression testing on a concrete test block, there is only one testing station. In this way, when the structural strength of the concrete test block does not meet the standard and is crushed, this station needs to be cleaned, and the next concrete test block cannot participate in the testing work. In this way, when there are multiple concrete test blocks, it is easy to affect the overall testing efficiency. Therefore, to address this problem, an improved construction engineering concrete hardness testing device is needed. Utility Model Content

[0013] 2. The utility model can use the rubber sleeve to be pre-installed on the outer surface of the concrete test block to be tested, thereby isolating the extrusion detection area to form a safe and closed environment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a construction engineering concrete hardness detection device, comprising a bottom plate 1, a detection mechanism for detection work is provided on the upper end of the bottom plate 1, the detection mechanism comprises a column 2, a top plate 3, a first slider 4, a movable plate 5, an extrusion block 6, and a hydraulic cylinder 7. A plurality of columns 2 are evenly fixed on the upper end surface of the bottom plate 1, a top plate 3 is fixed on the upper end of the column 2, a first slider 4 is movably sleeved on the surface of the column 2, a movable plate 5 is fixed between the first sliders 4, and the movable plate 5 is fixed between the first sliders 4. An extrusion block 6 is fixedly provided at the middle part of the lower end of the movable plate 5, a hydraulic cylinder 7 is fixedly provided at the middle part of the lower end of the top plate 3, and a feeding mechanism for feeding materials to the lower end of the hydraulic cylinder 7 is provided at the upper end of the bottom plate 1. The feeding mechanism includes a slide rail 8, a second slider 9, a switching plate 10, and a concrete test block 11. A slide rail 8 is fixedly provided at the upper end of the bottom plate 1, and a second slider 9 is movably engaged with the outer surface of the slide rail 8. A switching plate 10 is fixedly provided at the upper end of the second slider 9, and a concrete test block 11 is provided on one side of the upper end of the switching plate 10.

[0021] The switching plate 10 has placement grooves 12 on both sides of its surface. The concrete test block 11 is clamped and arranged inside the placement groove 12. The concrete test block 11 to be tested is placed inside the placement groove 12, which can quickly fix the concrete test block 11 to be tested, so as to facilitate the subsequent extrusion test work of the hydraulic cylinder 7.

[0022] The lower end of the movable plate 5 is fixedly provided with a rubber sleeve 13 on the outside of the extrusion block 6. The rubber sleeve 13 can be sleeved on the outer surface of the concrete test block 11 to be tested, thereby isolating the extrusion test area to form a safe and closed environment, which can effectively prevent the concrete test block 11 from being crushed and splashed due to the extrusion and causing injuries.

[0023] The switching plate 10 is fixed with a fixing ring 14 on both sides of the surface, and a limiting hole 15 is provided on the upper end of the bottom plate 1. The fixing ring 14 and the limiting hole 15 can fix the switching plate 10;

[0024] The fixing ring 14 is provided with a latch 16 at the upper end, which can be easily inserted into the fixing ring 14 and the limiting hole 15, thereby fixing the position of the switching plate 10;

[0025] The movable end of the hydraulic cylinder 7 is fixedly connected to the movable plate 5. The contraction of the hydraulic cylinder 7 can drive the movable plate 5 to move up and down, thereby driving the extrusion block 6 and the rubber sleeve 13 to move up and down.

[0026] Working principle: When using this device, the inspection work of the concrete test block 11 is consistent with that in the prior art. The extrusion block 6 can be pushed downward by the extension of the hydraulic cylinder 7, and then the concrete test block 11 on the upper end of the switching plate 10 is squeezed by the extrusion block 6 to determine whether the concrete test block 11 will be damaged or broken under the predetermined pressure value. During the inspection, since there are two placement slots 12 on the switching plate 10 of this device, during this inspection time, the staff can place the next concrete test block 11 to be inspected into the other inspection slot, and can also use this time to clean the concrete test block 11 fragments in this placement slot 12. In this way, the inspection time of the previous concrete test block 11 is used for cleaning and loading and unloading, which can greatly improve the inspection efficiency of the device. After the inspection of one concrete test block 11 is completed, the concrete test block 11 in the other placement slot 12 can be moved to the lower end of the hydraulic cylinder 7 by pushing the second slider 9 to slide on the upper end of the slide rail 8, so that the next extrusion inspection work can be carried out immediately.

[0027] When the device is used, the rubber sleeve 13 can be pre-installed on the outer surface of the concrete test block 11 to be tested, thereby isolating the extrusion detection area to form a safe and closed environment. In this way, the concrete test block 11 can be effectively prevented from being injured due to substandard strength and splashing due to extrusion and crushing. In addition, the surface of the rubber sleeve 13 of the device is provided with corrugations, which is equivalent to the corrugated hose in the prior art and can be folded, so as not to affect the downward movement of the extrusion block and the movable plate 5 for extrusion detection.
