Description

Technical Field

[0001] This utility model relates to a device for testing the compressive strength of quick-setting concrete, belonging to the technical field of concrete compressive strength testing equipment. Background Art

[0002] Concrete is one of the most important building materials. It is made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, if necessary, admixtures and additives in a certain proportion, then uniformly mixing, compacting, and curing it. During the production process, many factors can affect the quality of concrete. Substandard concrete can compromise building safety; therefore, concrete quality testing is essential. Compressive strength is one of the most important technical indicators for testing concrete quality, significantly impacting the durability and safety of concrete structures.

[0003] Chinese Patent CN211877621U discloses a concrete compressive strength testing device. It includes a support frame, a driving component on the support frame, a clamping component on the support frame, a hydraulic cylinder on the support frame, a sliding bracket securely connected to the piston rod of the hydraulic cylinder, and a pressure sensor below the sliding bracket. The pressure sensor is electrically connected to a display device. In use, the concrete to be tested is placed on a base, the driving component drives the clamping component to compress the concrete, and the piston rod of the hydraulic cylinder pushes the sliding bracket to perform the compressive strength test. While this design can perform compressive strength testing on concrete, in actual use, the concrete blocks are easily broken under the strong pressure during the test, scattering in all directions. This poses a threat to the personal safety of the test personnel, and the scattered concrete blocks are difficult to clean up. Debris can easily enter the equipment, affecting its service life.

[0004] To address the aforementioned issues, this application proposes a device for testing the compressive strength of quick-setting concrete. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a quick-setting concrete compressive strength testing device that is simple in structure, highly safe, and convenient for collecting and cleaning concrete debris.

[0006] This utility model is achieved through the following technical solution: a device for testing the compressive strength of quick-setting concrete, comprising a hydraulic base, the hydraulic base including a base, a lifting mechanism disposed on the base, and a movable seat connected to the lifting mechanism, an upper pressure block connected to the bottom end of the movable seat, and a lower pressure block fixed on the base corresponding to the upper pressure block, characterized in that: it further includes a disassembly assembly and a protective assembly, the disassembly assembly including a protective shell and a mounting block, the protective shell being disposed on the upper part of the lower pressure block, the upper part of the protective shell being open, the mounting block being fixedly connected to the bottom outer side of the protective shell, and symmetrically arranged at both ends of the mounting block. The storage slot contains springs, the outer ends of which are connected to movable blocks movably disposed within the storage slots. A limit block is located at the end of the movable block. A slot adapted to a mounting block is provided on the lower pressure block. The protective shell is detachably connected to the lower pressure block via a mounting block at its bottom. The mounting block is inserted into the slot of the lower pressure block, and the limit block abuts against the inner wall of the slot. The protective assembly includes a cover plate and a retaining ring connected to the lower edge of the cover plate. The cover plate is secured to the upper opening of the protective shell via the retaining ring. An opening is provided on the cover plate for the upper pressure block to pass through.

[0007] In this invention, the disassembly component is detachably installed on the lower pressure block. During compressive strength testing, the concrete test block is placed inside the protective shell. The upper pressure block can then perform compressive strength testing on the concrete block inside the protective shell through an opening in the cover plate. The protective shell and protective component effectively prevent the concrete block from splashing out during the compressive strength test, ensuring high safety. When it is necessary to clean the concrete debris inside the protective shell, the protective shell is lifted, the limiting block presses against the moving block, and the limiting block retracts into the storage groove opened in the mounting block, thereby releasing the position restriction on the mounting block and enabling quick disassembly of the protective shell for easy cleaning of the concrete debris inside. After cleaning, the protective shell can be installed on the upper pressure block.

[0008] Furthermore, to ensure reliable installation and disassembly of the mounting block, the limiting block is designed with an arc shape, and the slot is provided with a positioning groove that cooperates with the limiting block, and the limiting block is engaged in the positioning groove.

[0009] Furthermore, to ensure reliable movement of the movable block, the movable block is adapted to the storage slot.

[0010] Furthermore, stabilizing blocks are symmetrically arranged on the movable block, and a stabilizing groove adapted to the stabilizing block is formed in the mounting block. The movable block slides within the mounting block via the stabilizing block and the stabilizing groove. By setting the stabilizing block and the stabilizing groove, the position of the movable block can be limited, ensuring the reliability of the operation.

[0011] Furthermore, to ensure safety, bolt holes are symmetrically provided on the retaining ring, and the retaining ring is connected to the protective shell by fixing bolts.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. By setting a disassembly component and a protective component, the concrete block to be tested can be placed inside the protective shell of the disassembly component. The protective shell and the protective component can effectively prevent the concrete block from splashing out during the compressive strength test, thus ensuring high safety. The disassembly component and the lower pressure block are detachably connected. When it is necessary to clean the concrete debris inside the protective shell, the protective shell is lifted up, and the limiting block retracts into the storage groove opened in the mounting block, thereby releasing the position restriction on the mounting block and realizing the quick disassembly of the protective shell. The structure is simple and cleaning is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0022] As shown in the attached figure, a device for testing the compressive strength of quick-setting concrete includes a hydraulic base 1, which is existing technology. The hydraulic base 1 includes a base 16, a lifting mechanism 12 mounted on the base 1, and a movable seat 13 connected to the lifting mechanism 12. The lifting mechanism 12 consists of two symmetrically arranged hydraulic cylinders. The movable seat 13 is connected to the piston rod of the hydraulic cylinder of the lifting mechanism. A guide rod 17 is provided on the base 16 to cooperate with the movable seat 13, allowing the movable seat 13 to move along the guide rod 17. An upper pressure block 14 is connected to the bottom end of the movable seat 13, and a lower pressure block 15 is fixedly mounted on the base 16 corresponding to the upper pressure block 14. A control panel 11 is also provided on the hydraulic base 1. The improvement of this utility model is that it also includes a disassembly component 2 and a protective component 3. The disassembly component 2 includes a protective shell 21 and a mounting block 22. The protective shell 21 is disposed on the upper part of the lower pressure block 15 and has an opening at the top. The mounting block 22 is fixedly connected to the bottom outer side of the protective shell 21. The two ends of the mounting block 22 are symmetrically provided with storage grooves 26. A spring 25 is disposed in the storage groove 26. The outer end of the spring 25 is connected to a movable block 23 that is movably disposed in the storage groove 26. The end of the movable block 23 is provided with a limiting block 24. A slot 29 adapted to the mounting block 22 is provided on the lower pressure block 15. The protective shell 21 is detachably connected to the lower pressure block 15 through the mounting block 22 at its bottom end. The mounting block 22 is inserted into the slot 29 of the lower pressure block 15. The limiting blocks 24 at both ends of the mounting block 22 abut against the inner wall of the slot 29 of the lower pressure block 15. When the mounting block 22 is inserted into the lower pressure block 15, the moving block 23 is pushed by the compression of the limiting block 24, causing the limiting block 24 to retract into the storage groove 26. After the mounting block 22 is installed in place, the moving block 23 is pushed by the spring 25 set in the storage groove 26, so that the limiting block 24 abuts against the inner wall of the lower pressure block 15 for installation and locking. To ensure the reliability of the installation and disassembly of the mounting block, in this embodiment, the limiting block 24 is set with an arc-shaped structure, and the slot 29 is provided with a positioning groove 210 that cooperates with the limiting block 24. The limiting block 24 is locked in the positioning groove 210. The protective component 3 includes a cover plate 31 and a retaining ring 32 connected to the lower edge of the cover plate 31. The cover plate 31 is locked onto the upper opening of the protective shell 21 by the retaining ring 32. The cover plate 31 has an opening for the upper pressure block 14 to pass through. To ensure that the cover plate 31 and the protective shell 21 are reliably fixed, bolt holes are symmetrically provided on the retaining ring 32, and the retaining ring 32 and the protective shell 21 are connected by fixing bolts 66.

[0023] To ensure reliable movement of the movable block 23, it is preferable that the movable block 23 is adapted to the storage slot 26.

[0024] To ensure reliable movement of the movable block 23, preferably, stabilizing blocks 27 are symmetrically arranged on the movable block 23, and a stabilizing groove 28 adapted to the stabilizing block 27 is formed in the mounting block 22. The movable block 23 slides within the mounting block 22 via the stabilizing block 27 and the stabilizing groove 28. By setting the stabilizing block 27 and the stabilizing groove 28, the position of the movable block 23 can be limited, ensuring reliable movement.

[0025] In use, the protective shell 21 is installed on the lower pressure block 15 via the mounting block 22. The concrete test block is placed inside the protective shell 21, and the protective component 3 is installed on the protective shell 21, allowing for concrete compressive strength testing. During the concrete compressive strength test, the upper pressure block 14 is pushed by the lifting mechanism 12 and the moving seat 13 to perform the test. The upper pressure block 14 can apply pressure to the concrete block inside the protective shell through the opening on the cover plate 31. The protective shell 21 and the protective component 3 effectively prevent the concrete block from splashing out during the compressive strength test, ensuring high safety. When it is necessary to clean the concrete debris inside the protective shell 21, the protective shell 21 is lifted, the limiting block 24 presses against the moving block 23, and the limiting block 24 retracts into the receiving groove 26 opened in the mounting block 22, thereby releasing the position restriction on the mounting block 22 and enabling quick disassembly of the protective shell 21. After the protective shell is removed, the concrete debris inside can be cleaned easily. After cleaning, the protective shell 21 is installed on the upper pressure block 15.

[0026] This utility model has a simple structure. The protective shell 21 and the protective component 3 can effectively prevent concrete blocks from splashing out during the compressive strength test, which is highly safe. The disassembly component is easy to disassemble and install, and the concrete debris inside the protective shell can be easily cleaned, which makes it highly practical.

[0027] The other parts in this embodiment are all existing technologies and will not be described in detail here.
