Description

Technical Field

[0001] This utility model relates to the technical field of anti-permeability testing instruments, specifically a rapid positioning and calibration device for anti-permeability test specimen trays. Background Technology

[0002] The impermeability test is a test to detect the ability of materials (such as concrete, asphalt, etc.) to resist liquid penetration. It is mainly used to evaluate their durability and waterproof performance.

[0003] The working principle is to apply pressurized water step by step, observe the water seepage of the specimen or measure the seepage height to determine the water resistance level. For example, the test ends when 3 out of 6 concrete specimens see water when they are soaked in water. It is mainly used to test the waterproof performance of concrete structures to ensure that they can resist the seepage of groundwater, chemical liquids, etc., and prevent steel corrosion and structural damage.

[0004] Concrete permeability testing requires the use of a permeability meter. Concrete permeability meters are widely used in the performance testing of artificial stone and concrete materials. For certain buildings, such as hydraulic structures, underwater, submerged, underground and other construction projects, special properties are required, namely permeability resistance. Permeability resistance refers to the ability of the materials used in the structure to resist the penetration of water and other liquid (light oil, heavy oil) media under pressure.

[0005] However, traditional permeability testers do not have a positioning and calibration structure between the specimen and the test chamber. Therefore, after the specimen is placed inside the test chamber, there may be a certain positional deviation between it and the bottom mold base, which will affect the accuracy of the final permeability test data and has certain shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a rapid positioning and calibration device for impermeable specimen trays to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid positioning and calibration device for a permeability testing specimen tray, comprising a permeability meter body, a base at the bottom of the permeability meter body, four evenly distributed specimen platforms mounted on the base, six circumferentially distributed outer mold cavities in each specimen platform, a specimen mold seat fixedly installed inside the bottom of each outer mold cavity, an inner groove on the upper surface of each specimen mold seat, a plurality of primary positioning grooves on the side wall of the inner groove, the plurality of primary positioning grooves being circumferentially distributed at equal intervals through the center point of the specimen mold seat, four calibration holes on the upper surface of the inner groove, the four calibration holes being circumferentially distributed at equal intervals, a water inlet groove on the outer surface of the inner groove, a water inlet hole at the center of the water inlet groove, a cavity base adapted to the inner groove being provided inside the specimen mold seat, and a primary positioning component adapted to the primary positioning groove being provided on the outer surface of the cavity base.

[0008] Preferably, the number of primary positioning elements and primary positioning slots are the same and their positions correspond one-to-one.

[0009] Preferably, a calibration pin adapted to the calibration hole is fixedly installed on the lower surface of the cavity base, and a test cavity is fixedly installed on the upper surface of the cavity base. The test cavity has a hollow structure design and a lower tray is provided inside the test cavity.

[0010] Preferably, the number of calibration posts is the same as the number of calibration holes, and the positions of the calibration posts and calibration holes correspond.

[0011] Preferably, four inner limiting grooves are formed on the inner wall of the test cavity, and the four inner limiting grooves are circumferentially distributed at equal intervals around the center point of the test cavity.

[0012] Preferably, the outer wall of the lower tray is provided with an external positioning member that is adapted to the inner limiting groove, and the upper surface of the lower tray is provided with a test piece.

[0013] Preferably, a sealing cap is provided on the top upper surface of the test cavity.

[0014] Preferably, a plurality of support columns are fixedly installed on both sides and the center of the upper surface of the base, and the top ends of the plurality of support columns are fixedly installed with upper end caps through the four test piece platforms.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model features a lower tray that can be used in conjunction with the test cavity. When calibrating the position of the lower tray, the outer positioning component of the lower tray can be aligned vertically with the inner limiting groove of the test cavity one by one. After alignment, the lower tray can be positioned inside the test cavity, thus achieving a better rapid positioning and calibration effect, improving the positional accuracy of the lower tray when it is placed, and resulting in a better positioning effect.

[0019] Meanwhile, this utility model can effectively complete the assembly positioning and accuracy reduction of the cavity base through the positioning and calibration structure between the cavity base and the mold base, avoiding structural position deviation after assembly. It has a good positioning and limiting effect. After the cavity base is positioned and connected to the mold base, the cavity base can effectively avoid rotation within the mold base due to the limiting effect of the primary positioning component and the calibration pin. It has a good structural stability, improves the use effect, and is more practical.

[0020] In summary, this invention, through the coordinated use of multiple positioning and limiting structures, enables rapid positioning and connection between the mold base and the cavity base, as well as between the test cavity and the lower tray. It offers excellent limiting and calibration effects, ensuring better positioning and connection characteristics between structures and preventing positional deviations after assembly. This guarantees the positioning and connection effect of the permeability testing instrument, providing better assembly posture limitation and more precise positioning and calibration. Consequently, it ensures the accuracy of the final permeability test data, preventing assembly positional deviations from affecting the test data. It is more practical, allows for faster and more accurate assembly, and features a simple overall positioning structure suitable for use. Attached Figure Description

[0030] Please see Figure 1-5 An embodiment of this utility model provides a rapid positioning and calibration device for a permeability test specimen tray, comprising a permeability instrument body 1. The permeability instrument body 1 is characterized in that a base 17 is provided at the bottom end, and four evenly distributed specimen platforms 18 are installed on the base 17. Each specimen platform 18 has six circumferentially distributed outer mold cavities 19, and a mold base 2 is fixedly installed inside the bottom end of each outer mold cavity 19.

[0031] For details, please refer to the appendix of the instruction manual. Figure 4 As shown, each mold base 2 has an inner groove 4 on its upper surface. Several primary positioning grooves 3 are provided on the side wall of the inner groove 4. The several primary positioning grooves 3 are distributed circumferentially at equal intervals through the center point of the mold base 2. Four calibration holes 5 are provided on the upper surface of the inner groove 4. The four calibration holes 5 are distributed circumferentially at equal intervals. A water inlet groove 6 is provided on the outer surface of the inner groove 4. A water inlet hole 7 is provided at the center of the water inlet groove 6. The water inlet hole 7 can ensure the normal entry of water for the anti-permeability test.

[0032] Furthermore, in order to improve the positioning and adaptation effect of the test mold base 2, the test mold base 2 is provided with a cavity base 8 that is adapted to the inner groove 4, that is, the cavity base 8 can be placed inside the inner groove 4. The outer surface of the cavity base 8 is provided with a primary positioning component 9 that is adapted to the primary positioning groove 3, that is, the primary positioning component 9 can be limited and slidably connected to the primary positioning groove 3. The number of primary positioning components 9 and the primary positioning groove 3 are the same and their positions correspond one-to-one. The lower surface of the cavity base 8 is fixedly installed with a calibration pin 10 that is adapted to the calibration hole 5, so as to ensure that the calibration pin 10 can be inserted into the calibration hole 5 to complete the rapid positioning and calibration work.

[0033] Furthermore, the number of calibration pins 10 is the same as the number of calibration holes 5, and the positions of the calibration pins 10 and calibration holes 5 correspond.

[0034] Based on the above structure, when it is necessary to assemble and connect the cavity base 8 and the mold base 2, the cavity base 8 can be placed above the mold base 2. At the same time, the primary positioning parts 9 of the cavity base 8 are aligned with the primary positioning grooves 3 of the mold base 2 one by one. After the primary positioning parts 9 are aligned with the primary positioning grooves 3, the cavity base 8 can be placed into the inner groove 4 of the mold base 2.

[0035] After the cavity base 8 is placed inside the inner groove 4, the primary positioning component 9 is placed in the primary positioning groove 3, and the calibration pin 10 at the bottom of the cavity base 8 can be inserted into the calibration hole 5. In this way, the positioning and calibration structure between the cavity base 8 and the mold base 2 can effectively complete the assembly positioning and accuracy reduction of the cavity base 8, avoiding structural position deviation after assembly. It has a good positioning and limiting effect. At the same time, after the cavity base 8 is positioned and connected to the mold base 2, the cavity base 8 can effectively avoid rotation within the mold base 2 due to the limiting effect of the primary positioning component 9 and the calibration pin 10. It has a good structural stability, improves the use effect, and is more practical.

[0036] In this embodiment, in order to ensure the normal cavity test effect, a test cavity 11 is fixedly installed on the upper surface of the cavity base 8. The test cavity 11 has a hollow structure design and a lower tray 14 is provided inside the test cavity 11.

[0037] In this embodiment, in order to improve the rapid positioning connection effect between the lower tray 14 and the test cavity, four inner limiting grooves 12 are provided on the inner wall of the test cavity 11. The four inner limiting grooves 12 are distributed circumferentially at equal intervals through the center point of the test wall.

[0038] Furthermore, an outer positioning element 15 is provided around the outer wall of the lower tray 14 to be used in conjunction with the inner limiting groove 12. In order to facilitate integrated production and use, the lower tray 14 and the outer positioning element 15 adopt an integrated molding structure design. A test piece 13 is provided on the upper surface of the lower tray 14.

[0039] This structural design allows the lower tray 14 to be used in conjunction with the test cavity 11. When calibrating the position of the lower tray 14, the outer positioning part 15 of the lower tray 14 can be aligned vertically with the inner limiting groove 12 of the test cavity 11 one by one. After vertical alignment, the lower tray 14 can be positioned inside the test cavity 11, thus achieving a better rapid positioning and calibration effect, improving the positional accuracy of the lower tray 14 when it is placed, and resulting in a better positioning effect.

[0040] In this embodiment, in order to perform a test sealing treatment on the upper port of the test cavity 11, a sealing cover 16 is provided on the top surface of the test cavity 11. In this way, the sealing cover 16 can seal the port of the test cavity 11 during the anti-permeability test.

[0041] In this embodiment, in order to ensure the structural integrity of the permeability tester, several support columns are fixedly installed on both sides and the center of the upper surface of the base 17, and the tops of the support columns are fixedly installed with upper end caps 20 through the four test specimen platforms.

[0042] In this embodiment, in order to facilitate the operation and settings of the permeability tester of this utility model, a side bracket 21 is fixedly installed on one side of the outer wall of the upper cover 20, and a control panel 22 is fixedly installed on the lower surface of the bottom end of the side bracket 21. The control panel 22 is a color touch screen display, and the control panel 22 is electrically connected to the control system of the permeability tester when in use.

[0043] Working principle: When using the permeability tester of this utility model, the test specimen 13 can be placed on the lower tray 14, and then the lower tray 14 is placed in the test cavity 11. After that, the test can be carried out by the conventional permeability tester test procedure.

[0044] This utility model features a lower tray 14 that can be used in conjunction with the test cavity 11. When calibrating the position of the lower tray 14, the outer positioning part 15 of the lower tray 14 can be aligned vertically with the inner limiting groove 12 of the test cavity 11 one by one. After vertical alignment, the lower tray 14 can be positioned inside the test cavity 11, thus achieving a better rapid positioning and calibration effect, improving the positional accuracy of the lower tray 14 when it is placed, and resulting in a better positioning effect.

[0045] Meanwhile, when it is necessary to assemble and connect the cavity base 8 and the mold base 2, the cavity base 8 can be placed above the mold base 2, and the primary positioning parts 9 of the cavity base 8 can be aligned with the primary positioning grooves 3 of the mold base 2 one by one. After the primary positioning parts 9 and the primary positioning grooves 3 are aligned, the cavity base 8 can be placed into the inner groove 4 of the mold base 2.

[0046] After the cavity base 8 is placed inside the inner groove 4, the primary positioning component 9 is placed in the primary positioning groove 3, and the calibration pin 10 at the bottom of the cavity base 8 can be inserted into the calibration hole 5. In this way, the positioning and calibration structure between the cavity base 8 and the mold base 2 can effectively complete the assembly positioning and accuracy reduction of the cavity base 8, avoiding structural position deviation after assembly. It has a good positioning and limiting effect. At the same time, after the cavity base 8 is positioned and connected to the mold base 2, the cavity base 8 can effectively avoid rotation within the mold base 2 due to the limiting effect of the primary positioning component 9 and the calibration pin 10. It has a good structural stability, improves the use effect, and is more practical.

[0047] In summary, this utility model, through the coordinated use of multiple positioning and limiting structures, can achieve rapid positioning and connection between the mold base 2 and the cavity base 8, as well as between the test cavity 11 and the lower tray 14. It has a good posture limiting and calibration effect, allowing the connection between structures to have better positioning characteristics, avoiding positional deviations after assembly. This ensures the positioning and connection effect of the permeability testing instrument, has good assembly posture limiting characteristics, and more accurate positioning and calibration effects, thus guaranteeing the accuracy of the final permeability test data. It avoids the impact of assembly position deviations on the test data, has better practicality, and allows for faster and more accurate assembly. Furthermore, the overall positioning structure is simple and suitable for use.
