Description

Technical Field

[0001] The invention relates to the technical field of concrete anti-seepage detection, in particular to a concrete anti-seepage detection device. Background Art

[0002] The impermeability of concrete is one of the indicators to measure the durability of concrete. Impermeability not only represents the ability of concrete to resist water flow, but also affects the concrete's resistance to carbonization and chloride ion penetration. Concrete impermeability meter is mainly used for testing the concrete's impermeability performance and determining the impermeability grade.

[0003] In the traditional technical process of concrete impermeability testing, there are several significant defects that need to be solved urgently. First, relying on a screw press to press the concrete specimen into the steel mold not only increases the cost of equipment purchase and maintenance, but also forces the experimenters to bear a heavy burden of physical labor, especially in the process of transporting the specimen to the testing location after being pressed in, which has an adverse impact on work efficiency and personnel health. Secondly, the fastening method of the steel mold and the bottom mold, that is, the mechanical connection of multiple screws and nuts, requires fine adjustment of each fastening point to ensure sealing. Due to the uncontrollability of human operation, such as uneven fastening or omissions, errors are easily introduced, affecting the accuracy and reliability of the test results. Moreover, this multi-screw design is also time-consuming and labor-intensive in the disassembly stage after the test is completed, which hinders the rapid separation and recycling of the specimen and the mold, thereby lengthening the overall test cycle and increasing time and economic costs.

[0094] A second screw rod 82, one end of which is rotatably connected to the second support 81, and the other end of which is fixedly connected to the end of another rotating shaft 54;

[0095] A threaded seat 83, wherein the threaded seat 83 is threadedly connected to the outer side of the second screw rod 82, wherein the number of the threaded seats 83 is two;

[0096] A push rod 84, which is fixedly mounted on the surface of the threaded seat 83 and can move synchronously with the movement of the threaded seat 83; and

[0097] The transmission member 85 is arranged on the concrete anti-permeability detector 1, one end of which is in contact with the push rod 84, and the other end is connected to the sliding connection member 73. The transmission assembly 8 is mainly composed of a second support 81, a second screw 82, a threaded seat 83, a push rod 84 and a transmission member 85. The second support 81 is fixedly mounted on a side surface of the mounting plate 51 close to the drive motor 52, providing a stable support for the second screw 82. One end of the second screw 82 is rotatably connected to the second support 81. The other end is fixedly connected to the end of another rotating shaft 54, so that when the driving motor 52 drives the second screw 82 to rotate through the rotating shaft 54, the rotational motion of the second screw 82 can be effectively transmitted and converted. The external thread of the second screw 82 is equally divided into two sections, and the two sections of the external thread are in opposite directions. This design enables the second screw 82 to simultaneously drive the two thread seats 83 to move to the opposite side or the opposite side when rotating. The inner side of the thread seat 83 is provided with a thread that is in contact with the external thread of the second screw 82. The matching internal thread ensures a close fit and precise transmission between the two. The push rod 84 is fixedly mounted on the surface of the threaded seat 83. Therefore, when the threaded seat 83 moves, the push rod 84 will also move synchronously. This design enables the transmission assembly 8 to convert rotational motion into linear motion and transmit force to the required position through the push rod 84. The transmission member 85 is arranged on the concrete impermeability tester 1, one end of which is in contact with the push rod 84, and the other end is connected to the sliding connection member 73. When the threaded seat 83 drives the two push rods 84 to move to the middle side, the push rod 84 will transmit the force to the sliding connection member 73 through the transmission member 85, thereby driving the sliding connection member 73 to move. Due to the staggered distribution and mutual connection relationship between the sliding support arm 74 and the sliding connection member 73, the movement of one sliding connection member 73 will drive the adjacent sliding connection member 73 and the sliding support arm 74 to move together. Finally, through the action of the limiting fixing member 75, the bottom mold 2 and the steel mold 3 can be firmly fixed together.

[0098] In a preferred embodiment, the present invention can be further configured as follows: Figure 6 , Figure 7 As shown; the transmission member 85 comprises:

[0099] The support 851 is fixedly mounted on the concrete anti-permeability detector 1, and its number and distribution position are adapted to the annular seat 71;

[0100] The connecting tube 852 is fixedly mounted on the support 851 and is arranged horizontally as a whole;

[0101] The abutting rod 853 is disposed through the connecting tube 852, wherein the abutting rod 853 can be relatively displaced with the connecting tube 852, wherein one end of the abutting rod 853 close to the pushing rod 84 is in contact with the pushing rod 84, and one end of the abutting rod 853 away from the pushing rod 84 is connected to the adjacent sliding connection member 73;

[0102] an annular ring 854, the annular ring 854 is fixedly mounted on the outer side of the abutting rod 853, and the annular ring 854 and the abutting rod 853 are integrally formed; and

[0103] Spring 855, spring 855 is sleeved on the outside of the abutting rod 853, and one end of the spring 855 is in contact with the annular ring 854, and the other end is in contact with the inner wall of the connecting tube 852. The support 851 is fixedly installed on the concrete impermeability tester 1, and its number and distribution position are adapted to the annular seat 71, ensuring that the transmission member 85 can accurately correspond to the annular seat 71 and the sliding connection member 73 thereon. The connecting tube 852 is fixedly installed on the support 851, and the whole is arranged horizontally, providing guidance and support for the abutting rod 853. A sliding hole is processed on the surface of the connecting tube 852, which is to allow the abutting rod 853 to move relatively in the connecting tube 852. The abutting rod 853 is arranged through the connecting tube 852, one end of which is in contact with the pushing rod 84, and the other end is connected to the adjacent sliding connection member 73. This design makes it possible for the pushing rod 84 to be driven by the transmission assembly 8. When displacement occurs, the displacement can be transmitted to the sliding connection 73 through the abutting rod 853, thereby achieving the fixation or release of the steel mold 3 and the bottom mold 2. The annular ring 854 is fixedly installed on the outer side of the abutting rod 853, and is integrally formed with the abutting rod 853, which enhances the structural strength of the abutting rod 853 and provides it with an interface for contact with the spring 855. The spring 855 is sleeved on the outer side of the abutting rod 853, one end of which is in contact with the annular ring 854, and the other end is in contact with the inner wall of the connecting tube 852. The spring 855 plays a role of reset and buffering here. When the pushing rod 84 pushes the abutting rod 853 to move toward the side of the sliding connection 73, the spring 855 will be compressed; and when the thrust of the pushing rod 84 disappears, the spring 855 will push the annular ring 854 and the abutting rod 853 to reset through its elastic force, thereby achieving automatic reset of the transmission member 85.

[0104] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 7As shown; a displacement hole is processed on the surface of the fixed shell 4, and the push rod 84 is located on the inner side of the displacement hole, wherein the push rod 84 as a whole can be arranged in a 7-shape, and a movable track seat is fixedly installed on the surface of the concrete impermeability detector 1, and a movable track member compatible with the movable track seat is fixedly installed on the surface of the push rod 84, wherein the push rod 84 can be slidably connected to the surface of the concrete impermeability detector 1 through the movable track seat and the movable track member, and a displacement hole is processed on the surface of the fixed shell 4, and this displacement hole provides the necessary space for the push rod 84, so that the push rod 84 can freely perform linear motion inside it. It is worth noting that the push rod 84 is designed to be arranged in a 7-shape as a whole. This design not only enhances the structural strength of the push rod 84, but also facilitates its connection with the movable track seat, and a movable track seat is fixedly installed on the surface of the concrete impermeability detector 1, and this movable track seat serves as a guide rail for the sliding of the push rod 84, ensuring the stability and Directionality, at the same time, a moving track member compatible with the moving track seat is fixedly installed on the surface of the push rod 84, and a tight sliding fit is formed between these moving track members and the moving track seat, so that the push rod 84 can slide along a predetermined trajectory. When the second screw 82 in the transmission assembly 8 rotates, it will drive the push rod 84 to perform linear motion through the threaded seat 83. Since one end of the push rod 84 is connected to the threaded seat 83, and the other end is connected to the moving track seat through the moving track member, the linear motion of the push rod 84 will be performed along the moving track seat. This design not only simplifies the transmission mechanism, but also improves the accuracy and reliability of the transmission. During the sliding process of the push rod 84, it will transmit the force to the sliding connection member 73 through the transmission member 85, thereby controlling the fixing or release of the bottom mold 2 and the steel mold 3 by the limiting fixing member 75. Since the sliding of the push rod 84 is stable and controllable, it can ensure that the fixing or release of the bottom mold 2 and the steel mold 3 by the limiting fixing member 75 is also accurate and reliable.

[0105] The specific working principle of a concrete anti-seepage detection device of the present invention is as follows:

[0106] The concrete specimen is first inserted into the steel mold 3, and then the steel mold 3 and the concrete specimen are placed on the placement seat 64 together, and the driving motor 52 in the driving assembly 5 is started to start working. The output end of the driving motor 52 drives the driving gear 53 to rotate axially. As the driving gear 53 rotates, the rotating shaft 54 ​​starts to rotate through the meshing action of the rack 56, the transmission gear 55 and the driving gear 53. Among them, one rotating shaft 54 ​​drives the threaded sleeve 63 to slide on the guide rod through the first screw rod 62, and the threaded sleeve 63 further pushes the pressing piece 65 to move toward one side of the concrete specimen, so that the concrete specimen is completely pressed into the steel mold 3;

[0107] After the pressing operation is completed, the steel mold 3 with the concrete test block is placed on the bottom mold 2 to ensure that the two positions correspond to each other, and the driving motor 52 is started again. At this time, the other rotating shaft 54 ​​drives the two threaded seats 83 to move in opposite directions through the second screw 82, that is, the two push rods 84 are displaced to one side of the adjacent abutting rod 853, and the push rod 84 slides in the connecting tube 852 through the abutting rod 853 and compresses the spring 855, and finally transmits the thrust of the abutting rod 853 to the sliding connection member 73;

[0108] Under the action of the driving force, the sliding connection member 73 slides along the wedge-shaped groove on the sliding base 72, and drives the column 741 and the extension arm 742 of the sliding support arm 74 to move. The extension arm 742 transmits the force to the adjacent sliding connection members 73, so that all the sliding connection members 73 move toward the center at the same time. With the displacement of the sliding connection members 73, the limiting fixing member 75 approaches and contacts the annular ring 9 on the outside of the steel mold 3. Since the inclined surfaces of the annular ring 9 and the limiting fixing member 75 are adapted to each other, during the downward displacement of the limiting fixing member 75, the annular ring 9 drives the steel mold 3 to move downward through the extrusion effect of the two inclined surfaces until the steel mold 3 is tightly fitted with the bottom mold 2, thereby achieving rapid fixation.

[0109] After confirming that the steel formwork 3 and the bottom formwork 2 are firmly fixed, prepare for the subsequent concrete impermeability test.

[0110] In summary, through the above steps, the concrete impermeability testing device realizes the pressing of concrete specimens and the rapid fixation of the steel mold and the bottom mold, thereby improving the testing efficiency and the convenience of operation.
