Description

Technical Field

[0001] This utility model relates to the technical field of concrete impermeability testing equipment, specifically a concrete block lifting component. Background Technology

[0002] The concrete block lifting assembly is a key device that assists in testing the impermeability of concrete and ejects the concrete block from the testing container after testing. It is installed on the impermeability testing machine.

[0003] Traditional concrete permeability testing and related jacking operations suffer from numerous problems due to the lack of specialized and well-designed jacking components. During testing, the concrete sample is not securely fixed, and it easily shifts and shakes during jacking operations, leading to distorted test data that fails to accurately reflect the concrete's true permeability resistance. Furthermore, while the traditional method simply places the concrete on the jacking component, the descent is fraught with problems. The concrete block often gets stuck in the permeability testing container, potentially damaging both the concrete block and the container, severely impacting testing efficiency, and increasing operational difficulty and cost. Therefore, a concrete block jacking component is proposed. Utility Model Content

[0035] Please see Figure 1-6 A concrete block lifting assembly includes a permeability testing component 1. The permeability testing component 1 has a fixing component 2 at its upper end and a lifting component 5 at its lower end. The fixing component 2 and the lifting component 5 are connected by an adjusting component 3, on which an installation component 4 is fitted. The permeability testing component 1 includes a sample container 101 for holding concrete. The fixing component 2 includes an end cap 201 covering the sample container 101, with a screw 202 mounted on the upper end of the end cap 201. The lifting component 5 is used to lift the concrete inside the sample container 101. The adjusting component 3 includes a round rod 301, a first connecting arm 302, and a second connecting arm 303. The axial direction of the round rod 301 is parallel to the direction in which the lifting component 5 lifts the concrete. One end of the first connecting arm 302 is fixed to the bottom of the round rod 301, and the other end is connected to the lifting component 5. One end of the second connecting arm 303 is rotatably connected to the top of the round rod 301, and the other end is threadedly connected to the screw 202.

[0036] It should be noted that this device is installed on the seepage detection machine. Compared with the traditional jacking component 5, it is more stable than the traditional jacking component 5 because it is equipped with an adjustment component 3 to connect the fixing component 2 and the jacking component 5. The end cover 201 and the top plate 502 work together to drive the concrete to move up and down.

[0037] In this embodiment, a retaining ring 304 is provided on the round rod 301, and a fixing bolt 305 is threadedly connected to the top of the round rod 301. The second connecting arm 303 is limited to the upper end of the retaining ring 304, and the upper end of the second connecting arm 303 abuts against the head of the fixing bolt 305.

[0038] It should be noted that the retaining ring 304 provides a lower limit for the position of the second connecting arm 303 on the round rod 301, while the fixing bolt 305, which is threaded to the top of the round rod 301, abuts against the upper end of the second connecting arm 303, thus providing an upper limit for the second connecting arm 303. This upper and lower limit structure fixes the position of the second connecting arm 303 on the round rod 301, ensuring the stability of the adjusting assembly 3 during the lifting process. This, in turn, ensures the normal and stable operation of the entire concrete block lifting assembly, preventing any impact on the fit between the end cap 201 and the sample container 101, as well as the normal operation of the lifting assembly 5, due to changes in the position of the second connecting arm 303. Furthermore, by loosening the fixing bolt 305 and rotating the second connecting arm 303 along the axis of the round rod 301, the end cap 201 can be quickly separated from the concrete, making it more convenient to use.

[0039] In this embodiment, the ejector plate 502 is located inside the sample container 101 and is in direct contact with the concrete. The output end of the electric push rod 501 passes through the bottom of the sample container 101 and is fixed to the ejector plate 502. This structure allows the power of the electric push rod 501 to be directly and effectively transmitted to the ejector plate 502, thereby realizing the lifting operation of the concrete inside the sample container 101. At the same time, the output end of the electric push rod 501 located outside the sample container 101 is fixedly connected to one end of the first connecting arm 302. The lifting component 5 is connected to the adjusting component 3 through the first connecting arm 302, so that the lifting component 5 can work in coordination with the adjusting component 3 during the movement, ensuring the coordination and stability of the entire mechanism during the lifting of concrete, and providing strong support for the accurate detection of concrete performance.

[0040] In this embodiment, the anti-permeability testing component 1 also includes a mounting top plate 102 fixed to the upper end of the sample container 101, and the sample container 101 is also provided with a water injection port 103 and an air filling hole 104.

[0041] It should be noted that the mounting plate 102 is used for installation with the anti-permeability testing equipment, which facilitates subsequent disassembly and maintenance. The water inlet 103 is used to connect to an external water supply device for anti-permeability testing of concrete. At the same time, the air inlet 104 can increase or decrease the air pressure inside the sample container 101 to achieve the sealing of the sample container 101.

[0042] In this embodiment, an adjustment handle 203 is provided at the top of the screw 202, providing a convenient operating method for the operator. When fine-tuning the position of the end cap 201 relative to the concrete is required, the operator only needs to rotate the adjustment handle 203 to rotate the screw 202, thereby causing the end cap 201 to move up and down through the transmission action of the adjustment component 3, achieving a stable contact with the concrete sample. This design makes the operation more intuitive and convenient, improving the accuracy and efficiency of the operation. A leakage sensor 204 is provided at the bottom of the end cap 201, which can monitor in real time whether there is leakage between the end cap 201 and the sample container 101. During the concrete impermeability testing process, if leakage occurs, it will directly affect the accuracy of the test results. The leakage sensor 204 can detect leakage problems in time, and transmit the leakage signal to the external monitoring equipment or control system through the lead post interface 206 connected to the leakage sensor 204 at the top, so that the operator can take timely measures to ensure the smooth progress of the testing process and the reliability of the test data.

[0043] In this embodiment, the mounting component 4 includes a block 401 that is sleeved with the round rod 301 and a mounting base 402 that is fixed to the block 401. The mounting base 402 has a mounting hole 403.

[0044] It should be noted that the square block 401, which is sleeved with the round rod 301, can ensure the stability of the round rod 301 moving up and down. At the same time, the mounting hole 403 opened on the mounting base 402 makes it easy to use bolts and other fasteners to fix the mounting base 402 to the corresponding anti-permeability testing equipment or workbench, ensuring that the entire concrete block lifting assembly will not shake or shift during operation, thus ensuring the stability and accuracy of the testing process.

[0045] In this embodiment, a circular groove 205 is provided at the bottom of the end cap 201, and a circular protrusion 105 is provided at the top of the sample container 101. The circular groove 205 and the circular protrusion 105 cooperate with each other.

[0046] It should be noted that this mating structure can play a precise positioning role. When installing the end cap 201, the circular groove 205 and the circular protrusion 105 can be quickly and accurately aligned, ensuring that the end cap 201 can be correctly placed on the sample container 101. This avoids affecting the sealing performance of the end cap 201 and the sample container 101 and the contact effect with the concrete due to installation position deviation, and at the same time improves the sealing performance of the device.

[0047] In summary, this concrete block lifting assembly cleverly utilizes the up-and-down movement of the electric push rod 501 of the lifting assembly 5. With the coordinated action of the adjusting assembly 3, it moves the end cap 201 to precisely align with the container sample. Simultaneously, rotating the adjusting handle 203 further fine-tunes the position of the end cap 201 relative to the concrete, achieving a stable connection. This effectively solves the problems of unstable concrete sample fixation and easy displacement / shaking during traditional testing methods, ensuring the accuracy of the test data. Furthermore, the electric push rod 501 drives the ejector plate 502, and the rational layout of the adjusting assembly 3 and the installation assembly 4 allows the concrete to move smoothly during both rising and falling, avoiding descent jamming, improving testing efficiency, and reducing operational difficulty and cost.

[0048] Working principle: When the concrete block lifting component is working, the concrete is first placed in the sample container 101, water is injected through the water inlet 103 connected to the external water supply device, and the air pressure inside the container is adjusted by the air inlet 104 to achieve sealing, thus preparing for the seepage resistance test.

[0049] During testing, concrete is first placed on the ejector plate 502. The fixing bolts 305 are loosened while the second connecting arm 303 is rotated, positioning the end cap 201 directly above the concrete block. The fixing bolts 305 are then tightened, and the screw 202 is rotated via the adjusting handle 203 to bring the end cap 201 into contact with the concrete. The electric push rod 501 then moves downwards, causing the ejector plate 502 to lower the concrete. The end cap 201 also moves smoothly downwards with the concrete, preventing jamming. A leakage sensor 204 at the bottom of the end cap 201 monitors for leakage in real time. If leakage is detected, the signal is transmitted to external equipment via the lead-in pin interface 206 for timely handling, ensuring smooth testing.

[0050] Upon completion of the inspection, the electric push rod 501 of the lifting assembly 5 is activated, and its output end drives the ejector plate 502 to move upward and lift the concrete. Simultaneously, the output end of the electric push rod 501, via the first connecting arm 302, moves the round rod 301. The round rod 301 is limited by the retaining ring 304, causing the second connecting arm 303 to move the end cover 201 upward. At the same time, rotating the adjusting handle 203 at the top of the screw 202 separates the end cover 201 from the concrete. Simultaneously, loosening the fixing bolt 305 and rotating the second connecting arm 303 allows for quick separation of the end cover 201 from the concrete, facilitating repeated loading and unloading.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
