Generally, cement is used as the cementing material, sand and stone are used as aggregates, and then mixed with water in a certain proportion and stirred to obtain cement concrete, which can be widely used in civil engineering.

[0003] The compressive strength is one of the important indicators for evaluating the performance of concrete. Through the compressive strength test, the actual strength of the concrete can be understood, so as to judge whether it meets the design requirements and ensure the bearing capacity and safety of the building structure. However, there are some problems in the use of the previous concrete compressive strength testing devices, such as not having the advantage of being easy to install and fix, which brings trouble to the user to fix the concrete compressive strength testing device and cannot meet the needs of the current market.

However, there will still be a problem that the concrete after the test is easy to adhere to the surface of the device, which is not convenient for the user to clean the concrete and increases the work burden of the user. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a protection structure for detecting the compressive strength of concrete to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A protective structure for detecting the compressive strength of concrete, comprising a base; a placement plate is clamped inside the base, and a fixing plate is inside the base, which is clamped with both sides of the placement plate. A pulling block is fixedly installed at one end of the placement plate, and a protective cover is fixedly installed on the top of the base. A protective door is rotatably connected to one end of the protective cover. A pressing plate is arranged inside the protective cover. A hydraulic cylinder is fixedly installed on the top of the protective cover, and the hydraulic cylinder extends into the protective cover and is fixedly connected to the top of the pressing plate. A scraping plate is fixedly installed at the other end of the top of the placement plate, and a groove is formed at the top of the scraping plate. Clamping plates are slidably clamped on both sides of the protective cover, and connecting plates are arranged on both sides of the protective cover, which are fixedly connected to the outer sides of the clamping plates. A limiting component is arranged on the top of the connecting plate, and the limiting component is used to limit the connecting plate.

[0008] By installing the placement plate, the concrete can be placed. After the concrete detection is completed, the concrete is likely to adhere to the inner wall of the protective cover, the inner side of the clamping plate and the bottom of the pressing plate. The hydraulic cylinder drives the pressing plate to move to the highest position. At this time, the top of the scraping plate is just at the same horizontal line as the bottom of the pressing plate. By pulling the placement plate towards one end, the scraping plate can be driven to slide along the inner wall of the protective cover, the inner side of the clamping plate and the bottom of the pressing plate towards one end, so as to scrape off the concrete adhering to the inner wall of the protective cover, the inner side of the clamping plate and the bottom of the pressing plate, realizing the cleaning of the device and taking out the concrete at the same time, reducing the work burden of the user. Before the scraping plate needs to be moved into the protective cover again, the limiting component can be separated from the protective cover, and the bolt can be removed at the same time. Then, pull the connecting plate outwards to move the clamping plate outwards for a certain distance, so as to ensure that the clamping plate cannot contact the scraping plate during the subsequent process of moving the scraping plate into the protective cover, thereby reducing the wear between the scraping plate and the clamping plate and prolonging the service life of the scraping plate and the clamping plate.

[0009] A further improvement of the technical solution of the present utility model lies in that: the limiting component includes a limiting block, which is fixedly connected to the top of the connecting plate. A clamping block is slidably installed inside the limiting block through a spring, and the clamping block is fitted with the inside of the protective cover. A pulling plate is arranged on the top of the limiting block, and the pulling plate penetrates through the inside of the spring and is fixedly connected to the top of the clamping block.

[0010] Adopting the above technical solution, in this solution, the elastic force of the spring itself can squeeze the clamping block downwards, so that the clamping block can be clamped into the inside of the protective cover to limit the connecting plate and the clamping plate. By pulling the pulling plate upwards, the clamping block can be pulled upwards to facilitate the separation of the clamping block from the protective cover, so as to facilitate the movement of the connecting plate and the clamping plate.

[0011] A further improvement of the technical solution of the present utility model lies in that: the inner side of the clamping block is an inclined surface inclined towards the top.

[0012] With the above technical solution, in this solution, by setting the inner side of the clamping block as an inclined surface that slopes upward, during the process of the clamping block being inserted into the protective cover from the outside, the protective cover can directly squeeze the clamping block upward, eliminating the need for the user to first pull the clamping block upward, reducing the operation steps, and thus facilitating the quick insertion of the clamping block into the protective cover.

[0013] A further improvement of the technical solution of the present utility model lies in that: a connecting block is fixedly installed on the outer side of the connecting plate, and a bolt is inserted into the top of the connecting block, and the bolt is fitted into the inside of the base.

[0014] With the above technical solution, in this solution, by inserting the bolt into the connecting block and the inside of the base, the connecting block can be limited, thereby fixing the bottom of the connecting plate, achieving a strengthening effect.

[0015] A further improvement of the technical solution of the present utility model lies in that: a plurality of sliders are fixedly installed on the top and bottom of the clamping plate, and each slider is slidably connected to the inside of the protective cover.

[0016] With the above technical solution, in this solution, by installing the sliders, the sliding trajectory of the clamping plate inside the protective cover can be guided and limited, thereby preventing the clamping plate from detaching from the inside of the protective cover.

[0017] A further improvement of the technical solution of the present utility model lies in that: a protective plate is fixedly installed on the top of the pressing plate around the hydraulic cylinder, and the top of the pressing plate around the hydraulic cylinder is an inclined surface that slopes downward from the outside to the bottom.

[0018] With the above technical solution, in this solution, by installing the protective plate, the sliding trajectory of the pressing plate driven by the hydraulic cylinder can be guided and limited, thereby ensuring that the pressing plate can move in a straight line. By setting the top of the pressing plate as an inclined surface that slopes downward from the outside to the bottom, when the concrete fragments fly onto the top of the pressing plate, they can directly slide down through the inclined surface, facilitating the subsequent collection and cleaning of the concrete.

[0019] A further improvement of the technical solution of the present utility model lies in that: a baffle is fixedly installed on the top inside the protective cover, and the bottom of the baffle is an inclined surface that slopes upward from the inside, and this inclined surface matches the inclined surface of the top of the pressing plate.

[0020] With the above technical solution, in this solution, by installing the baffle, the highest position of the pressing plate inside the protective cover can be limited, thereby ensuring that the pressing plate can move to just be at the same horizontal line as the top of the scraping plate, facilitating the scraping of the concrete at the bottom of the pressing plate by the scraping plate.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0022] 1. The present utility model provides a protective structure for detecting the compressive strength of concrete. After the concrete detection is completed, the hydraulic cylinder drives the pressing plate to move upward and fit with the baffle. Then, the placement plate is pulled towards one end, and at the same time, the scraper can scrape off the concrete adhered to the inner wall of the protective cover, the inner side of the clamping plate, and the bottom of the pressing plate, so as to completely remove the concrete, thereby reducing the workload of the user.

[0023] 2. The present utility model provides a protective structure for detecting the compressive strength of concrete. Before moving the scraper into the interior of the protective cover, the connecting plate can be pulled outward to move the clamping plate outward by a certain distance, so as to ensure that during the subsequent process of moving the scraper into the interior of the protective cover, the clamping plate cannot come into contact with the scraper, reducing the wear between the scraper and the clamping plate.

[0024] 3. The present utility model provides a protective structure for detecting the compressive strength of concrete. Through the sequential cooperation between the limiting components, the clamping plate can be limited, so as to facilitate the subsequent scraping of the concrete adhered to the inner side of the clamping plate by the scraper. The connecting plate can be strengthened by installing bolts and connecting blocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following further describes the present utility model in detail with reference to the embodiments:

[0034] Embodiment 1

[0035] As Figure 1 、 Figure 2 and Figure 4 shown, the present utility model provides a protective structure for detecting the compressive strength of concrete, including a base 1; a placing plate 3 is clamped inside the base 1, and a fixing plate 101 is inside the base 1. The fixing plate 101 is clamped with both sides of the placing plate 3. A pulling block 301 is fixedly installed at one end of the placing plate 3. A protective cover 2 is fixedly installed on the top of the base 1. A protective door 201 is rotatably connected to one end of the protective cover 2. A pressing plate 7 is arranged inside the protective cover 2. A hydraulic cylinder 6 is fixedly installed on the top of the protective cover 2. The hydraulic cylinder 6 extends into the protective cover 2 and is fixedly connected to the top of the pressing plate 7. A scraping plate 10 is fixedly installed at the other end of the top of the placing plate 3. A groove is formed at the top of the scraping plate 10. Clamping plates 11 are slidably clamped on both sides of the protective cover 2. Connecting plates 4 are arranged on both sides of the protective cover 2. The connecting plates 4 are fixedly connected to the outer sides of the clamping plates 11. A limiting member 5 is arranged on the top of the connecting plates 4. The limiting member 5 is used to limit the connecting plates 4.

[0036] In this embodiment, the concrete can be placed by installing the placing plate 3. After the concrete detection is completed, the concrete is likely to adhere to the inner wall of the protective cover 2, the inner side of the clamping plate 11, and the bottom of the pressing plate 7. The hydraulic cylinder 6 drives the pressing plate 7 to move to the highest position. At this time, the top of the scraping plate 10 is just at the same horizontal line as the bottom of the pressing plate 7. By pulling the placing plate 3 towards one end, the scraping plate 10 can be driven to slide along the inner wall of the protective cover 2, the inner side of the clamping plate 11, and the bottom of the pressing plate 7 towards one end, so as to scrape off the concrete adhering to the inner wall of the protective cover 2, the inner side of the clamping plate 11, and the bottom of the pressing plate 7, realizing the cleaning of the device and taking out the concrete at the same time, reducing the working burden of the user. Before the scraping plate 10 needs to be moved into the protective cover 2 again, the limiting member 5 can be separated from the protective cover 2, and the bolt 8 can be removed at the same time. Then, the connecting plate 4 is pulled outwards, and the clamping plate 11 is moved outwards by a certain distance, so as to ensure that the clamping plate 11 cannot contact the scraping plate 10 during the subsequent process of moving the scraping plate 10 into the protective cover 2, thereby reducing the wear between the scraping plate 10 and the clamping plate 11 and extending the service life of the scraping plate 10 and the clamping plate 11.

[0037] Embodiment 2

[0038] As Figure 3 、 Figure 4 and Figure 5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the limiting member 5 includes a limiting block 501, which is fixedly connected to the top of the connecting plate 4. A clamping block 502 is slidably installed inside the limiting block 501 through a spring 503. The clamping block 502 is fitted into the inside of the protective cover 2. A pulling plate 504 is arranged on the top of the limiting block 501. The pulling plate 504 passes through the inside of the spring 503 and is fixedly connected to the top of the clamping block 502. The inner side of the clamping block 502 is an inclined surface inclined upward. A connecting block 401 is fixedly installed on the outside of the connecting plate 4. A bolt 8 is inserted into the top of the connecting block 401. The bolt 8 is fitted into the inside of the base 1. A plurality of sliding blocks 1101 are fixedly installed on the top and bottom of the clamping plate 11. Each sliding block 1101 is slidably connected to the inside of the protective cover 2.

[0039] In this embodiment, the elastic force of the spring 503 itself can squeeze the clamping block 502 downward, so that the clamping block 502 can be clamped into the inside of the protective cover 2 to limit the connecting plate 4 and the clamping plate 11. By pulling the pulling plate 504 upward, the clamping block 502 can be pulled upward to facilitate the separation between the clamping block 502 and the protective cover 2, so as to facilitate the movement of the connecting plate 4 and the clamping plate 11. By setting the inner side of the clamping block 502 as an inclined surface inclined upward, during the process of the clamping block 502 being clamped into the inside of the protective cover 2 from the outside, the protective cover 2 can directly squeeze the clamping block 502 upward without the user having to pull the clamping block 502 upward first, reducing the operation steps, so as to facilitate quickly clamping the clamping block 502 into the inside of the protective cover 2. By inserting the bolt 8 into the connecting block 401 and the base 1, the connecting block 401 can be limited, so as to fix the bottom of the connecting plate 4, achieving a strengthening effect. By installing the sliding blocks 1101, the sliding trajectory of the clamping plate 11 inside the protective cover 2 can be guided and limited, so as to prevent the clamping plate 11 from separating from the inside of the protective cover 2.

[0040] Embodiment 3

[0041] As Figure 1 and Figure 2 shown, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, a protective plate 701 is fixedly installed on the top of the pressing plate 7 around the hydraulic cylinder 6. The top of the pressing plate 7 around the hydraulic cylinder 6 is an inclined surface inclined from the periphery to the bottom.

[0042] In this embodiment, by installing the protective plate 701, the sliding trajectory of the pressing plate 7 driven by the hydraulic cylinder 6 can be guided and limited, so as to ensure that the pressing plate 7 can move in a straight line. By setting the top of the pressing plate 7 as an inclined surface inclined from the periphery to the bottom, when the concrete fragments fly onto the top of the pressing plate 7, they can directly slide down through the inclined surface, so as to facilitate the subsequent collection and cleaning of the concrete.

[0043] Example 4

[0044] As Figure 1 、 Figure 2 and Figure 6 shown, on the basis of Embodiment 3, the present utility model provides a technical solution: Preferably, a baffle 9 is fixedly installed at the top inside the protective cover 2, the bottom of the baffle 9 is an inclined surface that slopes towards the top inside, and this inclined surface matches the inclined surface at the top of the pressing plate 7.

[0045] In this embodiment, by installing the baffle 9, the highest position of the pressing plate 7 inside the protective cover 2 can be limited, so as to ensure that the pressing plate 7 can move to just be at the same horizontal line as the top of the scraping plate 10, thereby facilitating the use of the scraping plate 10 to scrape the concrete at the bottom of the pressing plate 7.

[0046] Next, the working principle of the protective structure for concrete compressive strength detection will be specifically described.

[0047] As Figures 1-6 shown, after the user places the concrete on the top of the placing plate 3, the hydraulic cylinder 6 is used to drive the pressing plate 7 to move downward, so as to realize the detection of the compressive strength of the concrete. After the concrete detection is completed, the concrete is likely to adhere to the inner wall of the protective cover 2, the inside of the clamping plate 11, and the bottom of the pressing plate 7. At this time, the hydraulic cylinder 6 drives the pressing plate 7 to move upward again, making the top of the pressing plate 7 fit with the baffle 9, and then pulling the placing plate 3 towards one end, while driving the scraping plate 10 to scrape the concrete adhered to the inner wall of the protective cover 2, the inside of the clamping plate 11, and the bottom of the pressing plate 7, and at the same time taking out the concrete, which reduces the working burden of the user. Before the scraping plate 10 needs to be moved into the protective cover 2 again, the user can remove the bolt 8, pull the pull plate 504 upward, and at the same time separate the clamping block 502 from the protective cover 2, then pull the connecting plate 4 outward, move the clamping plate 11 outward for a certain distance, and then move the scraping plate 10 into the protective cover 2. At the same time, the clamping plate 11 cannot contact the scraping plate 10, thereby reducing the wear between the scraping plate 10 and the clamping plate 11. Then the user pushes the connecting plate 4 inward to completely snap the clamping plate 11 into the protective cover 2, so as to facilitate the compressive test of the concrete again.

[0048] The above has generally described the present utility model in detail, but on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
