Abstract
Description
Technical Field
[0001] This invention relates to the field of concrete product testing technology, and in particular to a device for testing the compressive strength of concrete products. Background Technology
[0002] Concrete products intended for underwater use require the preparation of concrete test blocks during production. The manufacturing process of these test blocks must be carried out under identical conditions, i.e., by placing them in water. After preparation, the concrete test blocks need to be tested for compressive strength using a concrete pressure testing machine. During testing, the concrete test block is placed on a support base of the machine, which has circular lines engraved on it. To ensure the accuracy of the compressive strength test, the position of the concrete test block needs to be adjusted, aligning its four corners with the circular lines. Then, the hydraulic cylinder is activated to move the upper pressure plate downwards, pressing down on the concrete test block. A pressure sensor records the pressure applied to the concrete test block, and the data is then analyzed by software installed on a computer to obtain the compressive strength value of the concrete test block.
[0003] The current method for testing the compressive strength of concrete products involves placing concrete test blocks prepared under the same conditions on a support base and then manually adjusting the position of the concrete test blocks multiple times to align the four corners of the concrete test blocks with the circular lines on the support base before conducting the compressive strength test. This process is time-consuming and requires multiple adjustments to ensure accurate placement, thus the ease of operation needs improvement. Therefore, this application provides a compressive strength testing device for concrete products to meet this requirement. Summary of the Invention

The device also includes:
[0007] The positioning mechanism includes a C-shaped positioning plate set on a support base, a square plate fixed to the side of the C-shaped positioning plate, the C-shaped positioning plate being used to position the concrete test block, and an inclined guide surface and a V-shaped surface being provided on the inner wall of the C-shaped positioning plate, the guide surface and the V-shaped surface being connected, the guide surface being used to guide the concrete test block into the C-shaped positioning plate, and the V-shaped surface being used to reduce the contact area between the C-shaped positioning plate and the concrete test block.
[0008] A cleaning mechanism is used to clean the top of the support base and the bottom of the pressure plate after testing.
[0009] Preferably, a cylinder is fixed to the side of the support base by a bracket, and a C-shaped push bar is fixed to the telescopic end of the cylinder. The C-shaped push bar is fixed to the side of the square plate away from the C-shaped positioning plate.
[0010] Preferably, the cleaning mechanism includes a vertical plate fixed to the top of the square plate, two guide sleeves fixed to the sides of both the square plate and the vertical plate, a guide column slidably connected vertically inside the guide sleeve, a limit block fixed to one end of the guide column, and a mounting base fixed to the other end of the guide column. Two rubber scrapers are fixed to the side of the mounting base, and the two rubber scrapers are used to clean the top of the support base and the bottom of the pressure plate, respectively. A long box is fixed to the bottom of the upper rubber scraper, and a slag discharge pipe is connected to the side of the long box. A collection box is hung on the vertical plate and is located below the slag discharge pipe. A U-shaped collection hopper is placed on the base, and the side of the collection hopper is slidably connected to the side of the support base. A slope three is provided at the bottom of the pressure plate, a notch one is opened on the side of the movable plate, and a slope four is provided on the support base.
[0011] Preferably, the rubber scraper has two symmetrical guide surfaces on its side.
[0012] Preferably, a stop bar is fixed to the bottom of the C-shaped positioning plate, the side of the stop bar is slidably connected to the side of the rubber scraper located below, a curved surface is provided on the side of the stop bar away from the rubber scraper, and a curved surface is provided on the guide surface of the rubber scraper located below.
[0013] Preferably, the rubber scraper has a groove.
[0014] Preferably, the inner wall of the collecting hopper is fixed with guide strips, which are in the shape of isosceles triangles.
[0015] Preferably, the vertical plate has reinforcing ribs fixed to its side, and the reinforcing ribs are fixed to the top of the square plate.
[0016] Preferably, the inner wall of the elongated box is provided with a first inclined surface and a second inclined surface, and the first inclined surface and the second inclined surface are connected.
[0017] Preferably, the movable plate has a vertical groove, and a C-shaped cover is slidably connected in the vertical groove. A positioning strip is fixed to the top of the C-shaped cover and fits against the top of the movable plate. A notch is provided at the bottom of the C-shaped cover.
[0018] Compared with the prior art, the present invention has at least the following beneficial effects:
[0019] In the above scheme, the positioning mechanism utilizes a C-shaped positioning plate to accurately position the concrete test block, ensuring its placement. The inclined guide surface within the C-shaped positioning plate facilitates placement of the concrete test block, while the V-shaped surface of the inner wall reduces the contact area between the concrete test block and the plate, preventing subsequent compression and adhesion to the inner wall and ensuring accurate positioning. This significantly reduces the time required to accurately position the concrete test block, eliminates the need for multiple adjustments, and enhances operational convenience while ensuring the accuracy of the concrete test block compressive strength test.
[0020] By using the cleaning mechanism, after testing, the two rubber scrapers of the cleaning mechanism clean the support base and pressure plate, preventing residue from remaining on the support base and pressure plate and affecting subsequent testing of concrete test blocks. The cleaning is more convenient, and the two rubber scrapers are tightly attached to the support base and pressure plate under the action of corresponding springs, making the cleaning of the support base and pressure plate more thorough. At the same time, the residue cleaned from the pressure plate falls into the long box and is collected by the collection box, preventing residue from the pressure plate from falling onto the support base and affecting the placement and positioning of subsequent concrete test blocks. The residue on the support plate falls into the collection hopper and is collected by the collection hopper, preventing residue from falling directly and causing dirt on the base.
[0021] The baffle strip creates a gap between the lower rubber scraper and the square plate. This baffle strip prevents residue from entering the gap and causing residue to remain, thus preventing residue from falling back onto the support during the rubber scraper's reset process.
[0022] By setting up curved surfaces one and two, with curved surface one located on the baffle and curved surface two located on the rubber scraper below, the design of curved surfaces one and two effectively reduces the adhesion of residue to the baffle and the rubber scraper below, effectively preventing the baffle and the rubber scraper below from becoming clean and tidy.

Detailed Implementation
[0039] The compressive strength testing device for concrete product manufacturing provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.
[0040] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0041] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.
[0042] like Figures 1-12 As shown, an embodiment of the present invention provides a device for testing the compressive strength of concrete products, including a base 1, a support seat 2 fixed on the base 1, a top seat 3 fixed on the base 1 via a column, a hydraulic cylinder 4 fixed on the top seat 3, the telescopic end of the hydraulic cylinder 4 movably passing through the top seat 3 and fixed with a movable plate 16, a pressure sensor 17 fixed at the bottom of the movable plate 16, and a pressure plate 18 fixed at the bottom of the pressure sensor 17. A concrete test block is placed on the support seat 2, and the hydraulic cylinder 4 drives the pressure plate 18 to move downwards. The compressive strength of the concrete test block can be tested through the cooperation of the pressure plate 18 and the pressure sensor 17. The device also includes:
[0043] The positioning mechanism 5 includes a C-shaped positioning plate 51 mounted on the support base 2. A square plate 54 is fixed to the side of the C-shaped positioning plate 51. The C-shaped positioning plate 51 is used to position the concrete test block. The inner wall of the C-shaped positioning plate 51 is provided with an inclined guide surface 53 and a V-shaped surface 52. The guide surface 53 and the V-shaped surface 52 are connected. The guide surface 53 is used to guide the concrete test block into the C-shaped positioning plate 51. The V-shaped surface 52 is used to reduce the contact area between the C-shaped positioning plate 51 and the concrete test block. The V-shaped surface 52 is used to make line contact between the C-shaped positioning plate 51 and the concrete test block, so that the concrete test block can still be effectively positioned while reducing the contact area between the C-shaped positioning plate 51 and the concrete test block.
[0044] The cleaning mechanism 9 is used to clean the top of the support base 2 and the bottom of the pressure plate 18 after testing. When cleaning the damaged concrete test block after the compressive strength test of the concrete test block is completed, the cleaning mechanism 9 is used to clean the damaged concrete test block. During the cleaning process, the C-shaped positioning plate 51 also comes into contact with the damaged concrete test block. Under the action of the V-shaped surface 52, it effectively prevents the concrete test block residue with high humidity from sticking to the inner wall of the C-shaped positioning plate 51. If it sticks, it can also automatically slide down under the action of the inclined surface of the V-shaped surface 52, thereby preventing the residue from sticking to the inner wall of the C-shaped positioning plate 51 and affecting the positioning of subsequent concrete test blocks.
[0045] like Figure 3 and Figure 4 As shown in this embodiment, a cylinder 6 is fixed to the side of the support base 2 by a bracket. A C-shaped pusher 7 is fixed to the telescopic end of the cylinder 6. The C-shaped pusher 7 is fixed to the side of the square plate 54 away from the C-shaped positioning plate 51. The positioning mechanism 5 and the cleaning mechanism 9 can be moved by the cooperation of the cylinder 6 and the C-shaped pusher 7. There is no need to manually adjust the position of the positioning mechanism 5 and the cleaning mechanism 9, making it more convenient to use.
[0046] like Figures 3-7As shown, in this embodiment, the cleaning mechanism 9 includes a vertical plate 8 fixed to the top of the square plate 54. Two guide sleeves 94 are fixed to the sides of both the square plate 54 and the vertical plate 8. A guide post 93 is vertically slidably connected inside the guide sleeve 94. A limit block 96 is fixed to one end of the guide post 93, and a mounting base 92 is fixed to the other end. Two rubber scrapers 91 are fixed to the side of the mounting base 92. The two rubber scrapers 91 are used to clean the top of the support base 2 and the bottom of the pressure plate 18, respectively. A long box 99 is fixed to the bottom of the upper rubber scraper 91. A slag discharge pipe 26 is connected to the side of the long box 99. A collection box 13 is hung on the vertical plate 8, located below the slag discharge pipe 26. A U-shaped collection hopper 14 is placed on the base 1. The side of the collection hopper 14 is slidably connected to the side of the support base 2. An inclined surface 3 19 is provided at the bottom of the pressure plate 18. A notch 1 24 is opened on the side of the movable plate 16. An inclined surface 4 27 is provided on the support base 2. After the concrete test blocks are tested, the damaged concrete test blocks and the resulting residue need to be cleaned. During cleaning, cylinder 6 is activated, and the piston rod of cylinder 6 extends, causing the two rubber scrapers 91 at square plate 54 to move forward. The lower rubber scraper 91 moves forward along the top of support seat 2 under the elastic force of the corresponding spring 95. The upper rubber scraper 91 moves downward under the guidance of the inclined surface 19 at the bottom of pressure plate 18, compressing the upper spring 95. When the upper rubber scraper 91 is in contact with the bottom of pressure plate 18, the upper rubber scraper 91 is pressed tightly against the bottom of pressure plate 18 under the elastic force of the upper spring 95. The two rubber scrapers 91 move forward along the bottom of pressure plate 18 and the top of support seat 2 respectively, thus cleaning the bottom of pressure plate 18 and the top of support seat 2 and preventing residue from remaining on the bottom of pressure plate 18 and the top of support seat 2, which would affect the positioning and compressive strength testing of subsequent concrete test blocks.
[0047] like Figure 8 As shown in this embodiment, the rubber scraper 91 has two symmetrical guide surfaces 98 on its side. By utilizing the design of the guide surfaces 98, when cleaning the support seat 2 and the pressure plate 18, the residue on the support seat 2 and the residue adhering to the bottom of the pressure plate 18 are guided to both sides by the guide surfaces 98, reducing the accumulation of residue on the front side of the rubber scraper 91 in the direction of movement, and ensuring the cleaning effect of the rubber scraper 91 on the support seat 2 and the pressure plate 18.
[0048] like Figure 10As shown in this embodiment, a baffle 12 is fixed to the bottom of the C-shaped positioning plate 51. The side of the baffle 12 is slidably connected to the side of the rubber scraper 91 located below. A curved surface 20 is provided on the side of the baffle 12 away from the rubber scraper 91, and a curved surface 21 is provided on the guide surface 98 of the rubber scraper 91 located below. The baffle 12 is used to prevent residue from entering between the rubber scraper 91 located below and the square plate 54, thereby preventing residue from falling back onto the support base 2 during the resetting process of the rubber scraper 91 located below.
[0049] like Figure 8 and Figure 11 As shown in this embodiment, the rubber scraper 91 is provided with a groove 97. The groove 97 is located at the top of the upper rubber scraper 91 and the bottom of the lower rubber scraper 91. The groove 97 divides the top of the upper rubber scraper 91 and the bottom of the lower rubber scraper 91 into two parts. If the front half does not clean the top of the support base 2 and the bottom of the pressure plate 18, it can be cleaned again through the rear half, thereby ensuring that the top of the support base 2 and the bottom of the pressure plate 18 are cleaned more thoroughly.
[0050] like Figure 12 As shown in this embodiment, a guide strip 15 is fixed to the inner wall of the collection hopper 14. The guide strip 15 is in the shape of an isosceles triangle. The guide strip 15 is used to guide the residue falling from the front side of the support 2, so that the residue is automatically dispersed to both sides of the guide strip 15, effectively reducing the accumulation of residue.
[0051] like Figure 7 As shown in this embodiment, the vertical plate 8 is fixed with a reinforcing rib on its side. The reinforcing rib is fixed to the top of the square plate 54. The reinforcing rib is used to improve the connection strength between the vertical plate 8 and the square plate 54 and to prevent the vertical plate 8 from deforming.
[0052] like Figure 9 As shown in this embodiment, the inner wall of the elongated box 99 is provided with inclined surface 10 and inclined surface 21 respectively. Inclined surface 10 and inclined surface 21 are connected. Inclined surface 10 and inclined surface 21 are used to guide the residue falling to the inner wall of the elongated box 99, so that the residue enters the slag discharge pipe 26 after being guided by inclined surface 10 and inclined surface 21, thereby reducing the residue residue in the elongated box 99.
[0053] like Figure 3 and Figure 4As shown in this embodiment, a vertical groove is provided on the movable plate 16, and a C-shaped cover 22 is slidably connected in the vertical groove. A positioning strip 23 is fixed to the top of the C-shaped cover 22 and fits against the top of the movable plate 16. A notch 25 is provided at the bottom of the C-shaped cover 22. When the compressive strength of the concrete test block is tested, the C-shaped cover 22 and the rearward-moving C-shaped positioning plate 51 cooperate to form a protective cover to prevent residue from splashing outward during the test. The notch 25 is used to prevent the rearward-moving rubber scraper 91 from hindering the downward movement of the C-shaped cover 22, ensuring that the bottom of the C-shaped cover 22 is stably fitted with the top of the support base 2, thereby achieving stable protection during the compressive strength test of the concrete test block.
[0054] Working principle: The prepared concrete test block is placed on the support base 2 and pushed to move the concrete test block so that the rear and left and right sides of the concrete test block are in contact with the inner wall of the C-shaped positioning plate 51. The C-shaped positioning plate 51 is used to position the concrete test block and ensure the accuracy of the concrete test block placement. After the concrete test block is accurately positioned, the piston rod of the cylinder 6 is shortened and drives the C-shaped positioning plate 51 to move backward through the C-shaped pusher 7 and the square plate 54, so that the C-shaped positioning plate 51 is separated from the concrete test block. At the same time, the square plate 54 drives the rubber scraper 91 located above to move backward through the vertical plate 8 and separate from the pressure plate 18, so as to prevent the rubber scraper 91 located above from affecting the downward movement of the pressure plate 18. Then, the hydraulic cylinder 4 is activated, and the piston rod of the hydraulic cylinder 4 is extended and drives the pressure block to move downward through the movable plate 16. After the pressure plate 18 contacts the concrete sample, it continues to press down. The compressive strength of the concrete sample is detected by the cooperation of the pressure block and the pressure sensor 17.
[0055] As the movable plate 16 moves downward, it also moves the C-shaped cover 22 downward. When the bottom of the C-shaped cover 22 is in contact with the top of the support base 2, the movable plate 16 continues to move downward along the surface of the C-shaped cover 22. The C-shaped cover 22, together with the rearward-moving C-shaped positioning plate 51, forms a protective cover to prevent residue from splashing outward during the testing process. After the test is completed, broken concrete test blocks and residue will be generated. After the test is completed, the piston rod of the hydraulic cylinder 4 shortens, causing the movable plate 16 and the pressure plate 18 to move upward. The movable plate 16, through the positioning strip 23, moves the C-shaped cover 22 upward to above the C-shaped positioning plate 51. Then, the cylinder 6 is activated, and the piston rod of the cylinder 6 extends, causing the two rubber scrapers 91 at the square plate 54 to move forward. The lower rubber scraper 91 moves forward along the top of the support base 2 under the elastic force of the corresponding spring 95, while the upper rubber scraper 91 is pressed by the pressure plate during its forward movement. Guided by the bottom slope 19, the plate 18 moves downward, compressing the upper spring 95. When the upper rubber scraper 91 is in contact with the bottom of the pressure plate 18, the upper rubber scraper 91 is pressed tightly against the bottom of the pressure plate 18 under the elastic force of the upper spring 95. The two rubber scrapers 91 move forward along the bottom of the pressure plate 18 and the top of the support seat 2 respectively, and cooperate with the C-shaped positioning plate 51 to clean the pressure plate 18 and the support seat 2, preventing residue from remaining on the bottom of the pressure plate 18 and the support seat 2. When the C-shaped positioning plate 51 comes into contact with the damaged concrete test block, the V-shaped surface 52 effectively prevents the concrete test block with high humidity from sticking to the inner wall of the C-shaped positioning plate 51. If sticking occurs, it can also automatically slide down under the slope of the V-shaped surface 52, thereby preventing residue from sticking to the inner wall of the C-shaped positioning plate 51 and affecting the positioning of subsequent concrete test blocks.
[0056] The residue generated during the cleaning process at the pressure plate 18 falls into the long box 99 and, guided by inclined surfaces 10 and 11, enters the slag discharge pipe 26. It then falls into the collection box 13 for collection, preventing residue from the pressure plate 18 from falling onto the support base 2 and affecting the subsequent placement and positioning of concrete test blocks. The residue on the support plate, guided by the second guide surface 98 on the lower rubber scraper 91, moves partially forward and partially to the sides of the support base 2. The forward-moving residue falls into the collection hopper 14 after being guided by the fourth inclined surface 27 on the support base 2, while the residue moving to the sides of the support base 2 also falls into the collection hopper 14 for collection, preventing direct fall and soiling of the base 1. When the lower rubber scraper 91 reaches the fourth inclined surface 27, it stops moving. At this time, the piston rod of the cylinder 6 begins to retract, and retracts to... Figure 4 As shown in the diagram, when it is necessary to test the compressive strength of the concrete test block again, simply repeat the above steps.
[0057] The residue inside the collection hopper 14 needs to be cleaned regularly. When cleaning, hold the handle of the collection hopper 14 and remove the collection hopper 14 from the base 1, then pour the residue out of the collection hopper 14, and then place the collection hopper 14 on the support seat 2 on the base 1.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
