Description

Technical Field

[0001] This utility model belongs to the field of concrete permeability testing technology, specifically, it relates to a concrete permeability testing device. Background Technology

[0002] Concrete is a general term for composite materials made by mixing gelling materials, aggregates, and water in appropriate proportions and then hardening them over a certain period of time. It is the most widely used man-made civil engineering material in the world. Concrete has high hardness, widely available raw materials, and low cost, and is widely used in structures such as houses, highways, military engineering, and nuclear power plants. To ensure the impermeability of concrete during its later use, a concrete permeability tester is used to test its impermeability performance.

[0003] In some existing concrete permeability testing instruments, the test mold and the mold base are connected and fixed with multiple bolts. This requires personnel to use specific wrenches to tighten them one by one during disassembly and assembly, which is cumbersome and affects the work efficiency of personnel and the testing efficiency of concrete. To address this, we propose a concrete permeability testing device. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A concrete permeability testing device includes a concrete permeability tester, a mold base installed at the top of the concrete permeability tester, a test mold connected to the top of the mold base, a valve knob connected to the front of the concrete permeability tester near the top, an operation panel installed on the front of the concrete permeability tester near the bottom, a clamping plate installed on the outer wall of the bottom of the test mold near the bottom, a positioning post installed at the bottom of the clamping plate, a positioning groove opened at the top of the mold base, the positioning post inserted into the positioning groove, a sealing ring installed at the top of the mold base, the sealing ring being in close contact with the bottom of the test mold, and a fixing component for connecting and fixing the test mold and the mold base at the top of the concrete permeability tester.

[0006] The fixing component includes a fixing cover, which is rotatably connected to the top of the concrete permeability tester. The fixing cover is snapped onto the outside of the clamping plate. A second boss is installed on the top of the inner wall of the fixing cover, and a first boss is installed on the top of the clamping plate. The bottom end of the second boss is slidably connected to the top end of the first boss. A disassembly groove is provided on the top of the fixing cover.

[0007] In a preferred embodiment of this utility model, there are four card plates and four disassembly slots, and the card plates and disassembly slots are adapted to each other. By setting the card plates, the card plates can be inserted into the fixing cover through the disassembly slots.

[0008] In a preferred embodiment of this utility model, a T-shaped limiting ring plate is installed at the bottom of the fixed cover, and a T-shaped limiting ring groove is opened at the top of the concrete permeability tester. The T-shaped limiting ring plate and the T-shaped limiting ring groove are rotatably connected. By setting the T-shaped limiting ring plate and the T-shaped limiting ring groove, the fixed cover can be limited, so that the fixed cover can be fixed and rotated at the top of the concrete permeability tester.

[0009] In a preferred embodiment of this utility model, a connecting plate is installed on the outer wall of the fixing cover near the bottom end, and a fastening bolt is threaded into the threaded hole of the connecting plate. A fixing ring groove is provided at the top of the concrete permeability detector, and the fastening bolt is inserted into the fixing ring groove. By setting the fastening bolt, the fastening bolt can be squeezed against the inner wall of the fixing ring groove, thereby fixing the fixing cover.

[0010] In a preferred embodiment of this utility model, an anti-slip pad is installed at the bottom of the fastening bolt. The anti-slip pad contacts the bottom of the inner wall of the fixing ring groove. By setting the anti-slip pad, the friction between the fastening bolt and the fixing ring groove can be increased, thereby improving the fixing stability.

[0011] In a preferred embodiment of this utility model, a handle is installed on the outer wall of the fixing cover.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention facilitates the assembly and disassembly of the test mold and mold base, reducing the tediousness of assembly and disassembly, thereby improving the work efficiency of personnel and the efficiency of concrete testing. It solves the problem that existing concrete permeability testers use multiple bolts to connect and fix the test mold and mold base, which requires personnel to use specific wrenches to tighten them one by one during assembly and disassembly, making the operation cumbersome and affecting the work efficiency of personnel and the efficiency of concrete testing.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 4 As shown, a concrete permeability testing device includes a concrete permeability tester 1, a mold base 3 installed at the top of the concrete permeability tester 1, a test mold 2 connected to the top of the mold base 3, a valve knob 19 connected to the front of the concrete permeability tester 1 near the top, an operation panel 18 installed on the front of the concrete permeability tester 1 near the bottom, a clamping plate 4 installed on the outer wall of the bottom of the test mold 2 near the bottom, a positioning post 8 installed at the bottom of the clamping plate 4, a positioning groove 9 opened at the top of the mold base 3, the positioning post 8 inserted into the positioning groove 9, a sealing ring 16 installed at the top of the mold base 3, the sealing ring 16 in close contact with the bottom of the test mold 2, and a fixing component for connecting and fixing the test mold 2 and the mold base 3 at the top of the concrete permeability tester 1.

[0023] The fixing component includes a fixing cover 7, which is rotatably connected to the top of the concrete permeability tester 1. The fixing cover 7 is snapped onto the outside of the clamping plate 4. A second boss 6 is installed on the top of the inner wall of the fixing cover 7, and a first boss is installed on the top of the clamping plate 4. The bottom end of the second boss is slidably connected to the top end of the first boss. A disassembly groove 17 is provided on the top of the fixing cover 7.

[0024] Furthermore, there are four of each of the card plate 4 and the disassembly slot 17, and the card plate 4 and the disassembly slot 17 are compatible.

[0025] The card plate 4 is designed so that it can be inserted into the fixing cover 7 through the disassembly slot 17.

[0026] Furthermore, a T-shaped limiting ring plate 10 is installed at the bottom of the fixed cover 7, and a T-shaped limiting ring groove 11 is opened at the top of the concrete permeability tester 1. The T-shaped limiting ring plate 10 and the T-shaped limiting ring groove 11 are rotatably connected.

[0027] The T-shaped limiting ring plate 10 and the T-shaped limiting ring groove 11 can limit the fixed cover 7, so that the fixed cover 7 can be fixed and rotated at the top of the concrete permeability tester 1.

[0028] Furthermore, a connecting plate 12 is installed on the outer wall of the fixed cover 7 near the bottom. A fastening bolt 15 is threaded into the threaded hole on the connecting plate 12. A fixing ring groove 13 is provided at the top of the concrete permeability tester 1, and the fastening bolt 15 is inserted into the fixing ring groove 13.

[0029] By setting the fastening bolt 15, the fastening bolt 15 can be pressed against the inner wall of the fixing ring groove 13, thereby fixing the fixing cover 7.

[0030] Furthermore, an anti-slip pad 14 is installed at the bottom of the fastening bolt 15, and the anti-slip pad 14 contacts the bottom of the inner wall of the fixing ring groove 13.

[0031] By setting the anti-slip pad 14, the friction between the fastening bolt 15 and the fixing ring groove 13 can be increased, thereby improving the fixing stability.

[0032] Furthermore, a handle is installed on the outer wall of the fixed cover 7.

[0033] The implementation principle of a concrete permeability testing device is as follows: In use, the concrete block to be tested can be placed into the mold 2, and then the mold 2 is installed on the mold base 3. The mold 2 drives the positioning column 8 into the positioning groove 9, and the mold 2 drives the clamping plate 4 into the disassembly groove 17. Then, by directly rotating the handle, the fixing cover 7 is rotated, causing the fixing cover 7 to move the second boss 6 in a circular motion. During the circular motion, the second boss will compress against the first boss, causing the first boss to push the mold 2 downwards to press the sealing ring 16 through the clamping plate 4. Finally, the first boss and the second boss are on the same vertical axis. Then, the fastening bolt 15 is tightened, causing the fastening bolt 15 to push the anti-slip pad 14 downwards to press the fixing groove, thus fixing the fixing cover 7. This completes the installation of the mold 2 and the mold base 3. Then, the concrete permeability testing instrument 1 is started, and the concrete block in the mold 2 can be tested for permeability. After the test is completed, further testing is required. When disassembling the test mold 2, the fastening bolts 15 can be loosened, and then the fixing cover 7 can be rotated again. This will cause the fixing cover 7 to move the second boss away from pressing the first boss, and the fixing cover 7 will move the disassembly groove 17 to the top of the clamping plate 4. Then, the test mold 2 can be lifted upwards, causing the test mold 2 to move the positioning column 8 away from the positioning groove 9, and the clamping plate 4 can pass through the fixing cover 7 through the disassembly groove 17, thus completing the disassembly of the test mold 2. The above structure facilitates the disassembly and assembly of the test mold 2 and the mold base 3, reducing the tediousness of disassembly and assembly, thereby improving the work efficiency of personnel and the efficiency of concrete testing. It solves the problem that the existing concrete permeability tester 1 uses multiple bolts to connect and fix the test mold 2 and the mold base 3, which requires personnel to use specific wrenches to tighten them one by one during disassembly and assembly, which is cumbersome and affects the work efficiency of personnel and the efficiency of concrete testing.
