Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a high-density concrete pressure value detector. Background Technology

[0002] Concrete refers to a mixture made by mixing cementitious materials (organic, inorganic, or organic-inorganic composites), granular aggregates, water, and chemical admixtures and mineral admixtures in appropriate proportions, or a composite material that forms a stoichiometric structure after hardening. Concrete undergoes pressure testing after being put into use or produced.

[0003] Existing equipment for concrete testing is usually open on all four sides, which makes it easy for residues and fragments to be detected during concrete testing, resulting in low safety. Furthermore, the existing concrete testing equipment is not convenient for cleaning up residual residues after use. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-density concrete pressure value detector, comprising a base, on which a square pad is fixedly installed, and a tray is clamped on the upper part of the square pad; columns are fixedly installed around the base, and a guide beam is movably fitted on the upper part of the columns; an upper beam is fixedly installed on the top of the columns, and a hydraulic cylinder is fixedly installed on the top of the upper beam; the output end of the hydraulic cylinder is fixedly connected to the guide beam; a strain gauge sensor is fixedly installed at the bottom of the guide beam, and a pressure plate is fixedly installed at the bottom of the strain gauge sensor, and an acrylic cover is threaded onto the pressure plate; a support rod is fixedly installed on the base, and an operation panel is fixedly installed on the support rod; the strain gauge sensor is electrically connected to the operation panel.

[0006] Furthermore, the square pad has slots on both sides, and pressure blocks are engaged through the slots.

[0007] Furthermore, a T-slot is provided on the base, and a T-bolt is installed on the pressure block, which is locked to the base by the T-bolt and the T-slot.

[0008] Furthermore, the lower part of the tray is provided with a square opening, which is engaged with a square pad block.

[0009] Furthermore, the outer side of the pressure plate is provided with external threads, and the inner side of the top end of the acrylic cover is provided with internal threads, and is threadedly connected to the pressure plate through the internal and external threads.

[0010] Furthermore, the acrylic cover corresponds to the position of the tray, and the inner diameter of the acrylic cover is larger than the outer diameter of the tray, ranging from 0.5cm to 3cm.

[0011] Compared with the prior art, this utility model provides a high-density concrete pressure value detector, which has the following beneficial effects:

[0012] 1. This high-density concrete pressure detector places a concrete test block in a tray and uses a hydraulic cylinder to drive the pressure plate to press down. The pressure that the concrete test block can withstand is tested by a strain gauge sensor. During the test, an acrylic cover will temporarily seal the test area as the pressure plate descends. This does not affect the observation of the test process and can also prevent the problem of concrete debris being splashed out when it is squeezed.

[0013] 2. This high-density concrete pressure value detector collects the compressed concrete fragments in a tray. Simply remove the tray to process the concrete fragments, which improves cleaning efficiency, makes it more convenient to use, and has a simple overall structure that is easy to manufacture and implement.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3This utility model discloses a high-density concrete pressure value detector, including a base 1, on which a square pad 2 is fixedly installed, and a tray 3 is clamped on the upper part of the square pad 2. Columns 4 are fixedly installed around the base 1, and a guide beam 5 is movably fitted onto the upper part of the columns 4. An upper beam 6 is fixedly installed on the top of the columns 4, and a hydraulic cylinder 7 is fixedly installed on the top of the upper beam 6. The output end of the hydraulic cylinder 7 is fixedly connected to the guide beam 5. A strain gauge sensor 8 is fixedly installed at the bottom of the guide beam 5, and a pressure plate 9 is fixedly installed at the bottom of the strain gauge sensor 8. An acrylic cover 10 is threaded onto the pressure plate 9. A concrete test block is placed in the tray 3, and hydraulic pressure is applied. Cylinder 7 drives pressure plate 9 to press down, and strain gauge sensor 8 tests the pressure resistance of concrete test blocks. During the test, acrylic cover 10 will follow the descent of pressure plate 9 to temporarily seal the test area. This does not affect the observation of the test process and can also prevent the problem of concrete fragments being splashed out when squeezed. The squeezed concrete fragments are concentrated in tray 3. The concrete fragments can be processed simply by removing tray 3, which is beneficial to improving cleaning efficiency and making it more convenient to use. The overall structure is simple and easy to manufacture and implement. A support rod 11 is fixedly installed on the base 1, and an operation panel 12 is fixedly installed on the support rod 11. The strain gauge sensor 8 is electrically connected to the operation panel 12.

[0020] Specifically, the square pad 2 has slots 13 on both sides, and a pressure block 14 is engaged through the slots 13.

[0021] In this embodiment, the slot 13 is an assembly structure used to lock the square pad 2 onto the base 1 in conjunction with the pressure block 14.

[0022] Specifically, the base 1 has a T-slot 15, and the pressure block 14 is equipped with a T-bolt 16, which is locked to the base 1 by the T-bolt 16 and the T-slot 15.

[0023] In this embodiment, the pressure block 14 is locked onto the base 1 by the T-bolt 16 and the T-slot 15. The pressure block 14 is used to tighten the pressure block, mainly to facilitate the adjustment of the position of the square pad 2.

[0024] Specifically, the lower part of the tray 3 is provided with a square opening 17, which is engaged with the square pad block 2.

[0025] In this embodiment, the square sleeve 17 is a connecting structure used for connecting and positioning the tray 3 and the square pad 2.

[0026] Specifically, the outer side of the pressure plate 9 is provided with an external thread 18, and the inner side of the top end of the acrylic cover 10 is provided with an internal thread 19, and is threadedly connected to the pressure plate 9 through the internal thread 19 and the external thread 18.

[0027] In this embodiment, the internal thread 19 and the external thread 18 facilitate the installation and disassembly of the acrylic cover 10 and the pressure plate 9.

[0028] Specifically, the acrylic cover 10 is positioned corresponding to the tray 3, and the inner diameter of the acrylic cover 10 is larger than the outer diameter of the tray 3, ranging from 0.5cm to 3cm.

[0029] In this embodiment, the acrylic cover 10 can temporarily enclose the test area as it descends with the pressure plate 9, thereby preventing the problem of debris being splashed out when the concrete is squeezed. At the same time, in order to avoid interference between structures, the inner diameter of the acrylic cover 10 must be larger than the outer diameter of the tray 3.

[0030] In use, the concrete test block is placed in the tray 3, and the hydraulic cylinder 7 drives the pressure plate 9 to press down. The strain gauge sensor 8 tests the pressure that the concrete test block can withstand. The pressure value can be displayed on the screen on the operation panel 12. During the test, the acrylic cover 10 will follow the descent of the pressure plate 9 to temporarily seal the test area. This does not affect the observation of the test process and can also prevent the problem of concrete fragments flying out when it is squeezed. The squeezed concrete fragments are concentrated in the tray 3. The concrete fragments can be disposed of simply by removing the tray 3, which helps to improve cleaning efficiency, makes it more convenient to use, and has a simple overall structure that is easy to manufacture and implement.

[0031] In summary, this high-density concrete pressure detector places a concrete test block in a tray 3, uses a hydraulic cylinder 7 to drive a pressure plate 9 to press down, and uses a strain gauge sensor 8 to test the pressure the concrete test block can withstand. During the test, an acrylic cover 10 temporarily seals the test area as the pressure plate 9 descends, preventing the concrete from being squeezed out and debris from splashing out without affecting the observation of the test process. The squeezed concrete fragments are concentrated in the tray 3, and the concrete fragments can be processed simply by removing the tray 3, which improves cleaning efficiency, makes it more convenient to use, and has a simple overall structure that is easy to manufacture and implement.
