Detailed implementation manners

[0018] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 10 drawings.

[0019] An embodiment of the present application discloses a pressure device for testing raw materials in highway engineering. The pressure device for testing raw materials in highway engineering refers to Figure 1 , and includes a pressure testing machine 1. The pressure testing machine 1 includes a base 11, a workbench 12, a test bench 13, a lower pressing plate 14 and columns 15. The workbench 12 is fixedly arranged on the base 11, the columns 15 are fixedly arranged on the workbench 12, the test bench 13 is fixedly arranged on the workbench 12 and is located between the columns 15, and the lower pressing plate 14 is slidably arranged between the columns 15. Further, the pressure testing machine 1 further includes a hydraulic cylinder 16, and the hydraulic cylinder 16 is used to drive the lower pressing plate 14 to apply a load to the test block.

[0020] Refer to Figure 1 and Figure 2, to improve the testing efficiency of the test blocks, a receiving plate 2 is rotatably arranged on the workbench 12. The receiving plate 2 is disc-shaped, and the rotation axis of the receiving plate 2 is perpendicular to the workbench 12 and is located on one side of the test bench 13. Further, a driving motor for driving the rotation of the receiving plate 2 is arranged on the workbench 12. The bottom of the receiving plate 2 is received on the test bench 13. The receiving plate 2 is used to place the test blocks. A plurality of placing notches 3 are formed in the receiving plate 2 and are evenly arranged along the circumferential direction of the receiving plate 2. The area of the placing notch 3 is larger than the area of the test block and smaller than the area of the test bench 13; Refer to Figure 2 and Figure 3 , a receiving member 4 and a positioning member 5 are arranged in the placing notch 3. The receiving member 4 is used to place the test block on the receiving plate 2 after the test block is placed in the placing notch 3, and the positioning member 5 is used to adjust the position of the test block so that the test block is located at the center of the placing notch 3.

[0021] When performing a strength test on the test block, first place the test block on the receiving plate 2. After the test block is located on the receiving plate 2, the test block is located in the placing notch 3 and is fixed in the placing notch 3 by the receiving member 4. Then, the positioning member 5 acts on the test block to make the test block located in the middle of the placing notch 3, so that the test block is in a separated state from the inner wall of the placing notch 3. Subsequently, rotate the receiving plate 2. The rotation of the receiving plate 2 drives the test block to move and be placed on the test bench 13. At this time, the bottom of the receiving plate 2 is placed on the test bench 13. Then, the test block is dropped onto the test bench 13 through the receiving member 4, and then the lower pressing plate 14 is slid to press the test block for testing. When the test block is damaged, rotate the receiving plate 2 again. The receiving plate 2 drives the adjacent test block to be placed on the test bench 13, thereby reducing the process of installing the test block and improving the testing efficiency of the test block.

[0022] Refer to Figure 4 and Figure 5 , in the embodiment of the present application, the receiving member 4 includes a receiving block 41 arranged in the placing notch 3. The receiving block 41 is strip-shaped. Two receiving blocks 41 are arranged and are respectively located on two opposite side walls of the placing notch 3. A sliding groove 6 is formed in the side wall of the placing notch 3. The receiving block 41 is slidably arranged in the sliding groove 6. The receiving member 4 further includes a first driving member for driving the receiving block 41 to slide in the sliding groove 6. The first driving member includes a first push rod 42 arranged in the sliding groove 6. The length direction of the output shaft of the first push rod 42 is parallel to the depth direction of the sliding groove 6. The receiving block 41 is fixedly arranged on the output shaft of the first push rod 42; when receiving the test block, start the first push rod 42. The first push rod 42 drives the receiving block 41 to slide out of the sliding groove 6 and then place the test block on the receiving block 41. The operation is simple and convenient; when the test block needs to fall onto the test bench 13, start the first push rod 42. The first push rod 42 pulls the receiving block 41 into the sliding groove 6, and the test block is separated from the receiving block 41 and falls onto the test bench 13. The operation is simple and convenient.

[0023] Refer toFigure 4 and Figure 5 , in the embodiment of the present application, in order to reduce the fragments that fall on the test bench 13 when the test block is broken, and thus reduce the fragments that fall on the workbench 12. Therefore, the bottom of the chute 6 penetrates through the receiving plate 2, the bottom of the receiving block 41 is flush with the bottom of the receiving plate 2, and both sides of the receiving block 41 are slidably clamped on the side wall of the chute 6. Further, the width of the receiving block 41 is equal to the width of the placing notch 3. After the ends of the receiving blocks 41 on both sides abut against each other, the receiving block 41 completely closes the placing notch 3. After the placing notch 3 is located behind the test bench 13, the bottom of the receiving block 41 abuts on the test bench 13, and the surface of the receiving block 41 facing away from the bottom wall of the chute 6 is inclined towards the top surface of the placing notch 3; after the test block is damaged by pressure, the broken test block falls on the receiving plate 2 and the test bench 13. At this time, the first push rod 42 is started, and the first push rod 42 pushes the receiving block 41 to slide out of the chute 6. Since the receiving block 41 abuts on the test bench 13 and the end face of the receiving block 41 is an inclined plane, when the receiving blocks 41 on both sides approach each other, the fragments on the test bench 13 are shoveled, so that the fragments are transferred from the test bench 13 to the receiving block 41, thereby reducing the fragments that fall on the test bench 13 and driving the test block to move away as the receiving plate 2 rotates.

[0024] Referring to Figure 6 and Figure 7 , after the receiving block 41 shovels the fragments on the test bench 13, there will be a lot of fine impurities and dust remaining on the test bench 13. Under the action of the impurities and dust, it will be difficult to vertically place the test block on the test bench 13. Therefore, in the embodiment of the present application, a plurality of installation cavities 7 are opened on the bottom wall of the receiving plate 2. The installation cavities 7 are located between adjacent placing notches 3. The openings of the installation cavities 7 face the workbench 12. A brush rod 8 is rotatably arranged in the installation cavity 7. The rotation axis of the brush rod 8 is perpendicular to the top wall of the installation cavity 7. A third driving member for driving the brush rod 8 to rotate to clean the surface of the test bench 13 is arranged in the installation cavity 7. The third driving member includes a first motor 9 arranged in the installation cavity 7. The length direction of the output shaft of the first motor 9 is perpendicular to the bottom wall of the installation cavity 7. The middle of the brush rod 8 is fixedly arranged on the output shaft of the first motor 9; when the receiving plate 2 rotates, the first motor 9 is started, and the first motor 9 drives the brush rod 8 to rotate. When the brush rod 8 rotates, the bristles on the brush rod 8 remove the fine impurities on the test bench 13, so that the test bench 13 is relatively clean and convenient for the test block to fall on the test bench 13.

[0025] Referring to Figure 4 and Figure 5, in the embodiment of the present application, the positioning member 5 includes a positioning rod 51 slidably disposed in the placement notch 3. The positioning rod 51 is located on the side wall of the placement notch 3. The positioning rods 51 are provided on the four side walls of the placement notch 3. The positioning rod 51 is located above the receiving block 41. The sliding direction of the positioning rod 51 is perpendicular to the side wall of the placement notch 3 where it is located. The positioning member 5 further includes a second driving member for driving the sliding of the positioning rod 51. The second driving member includes a second push rod 52 embedded in the receiving plate 2. The positioning rod 51 is coaxially disposed on the output shaft of the second push rod 52. When the test block falls off the receiving block 41, the second push rod 52 is started. The second push rod 52 drives the positioning rod 51 to slide. After the positioning rod 51 moves out of the placement notch 3, it abuts against the test block, so that the test block is located in the middle of the placement notch 3, and the operation is simple and convenient.

[0026] Refer to Figure 8 and Figure 9 , when the test block breaks on the test bench 13 and falls on the receiving plate 2, for the convenience of centralized processing of the test block, in the embodiment of the present application, a rotating rod 10 is rotatably disposed on the workbench 12. The receiving plate 2 is coaxially disposed on the rotating rod 10. The rotating rod 10 includes a first rod body 101 and a second rod body 102. The first rod body 101 is rotatably disposed on the workbench 12. The first rod body 101 is coaxially disposed on the output shaft of the driving motor. The receiving plate 2 is disposed on the second rod body 102. The first rod body 101 and the second rod body 102 are movably connected. The rotating rod 10 further includes a connecting member 17 coaxially connecting the first rod body 101 and the second rod body 102 and enabling the first rod body 101 and the second rod body 102 to have the same movement tendency. When the test block breaks and falls on the receiving block 41 and the receiving plate 2, the second rod body 102 is removed from the first rod body 101 or the edge of the receiving plate 2 is received on the workbench 12. After the edge of the receiving plate 2 is received on the workbench 12, the test block falls on the workbench 12, which is convenient for centralized processing of the test block. And under the action of the connecting member 17, it is convenient for the driving motor to drive the first rod body 101 to rotate and drive the receiving plate 2 to rotate.

[0027] Refer to Figure 8 and Figure 9, in the embodiment of the present application, the docking ends of the first rod body 101 and the second rod body 102 are both frustum-shaped, and magnets are provided on the inclined surfaces of the docking ends. After the second rod body 102 is separated from the first rod body 101, the edge of the receiving plate 2 is received on the workbench, and the inclined surface of the docking end of the second rod body 102 is adsorbed on the inclined surface of the docking end of the first rod body 101, so as to place the receiving plate 2 on the workbench 12 in an inclined state; the second rod body 102 is driven to drive the receiving plate 2 to be placed obliquely on the workbench 12. At this time, the frustum of the second rod body 102 is adsorbed on the frustum of the first rod body 101, preventing the receiving plate 2 from being directly laid flat on the workbench 12, thus facilitating the cleaning of the fragments and impurities on the receiving plate 2; and when the receiving plate 2 is inclined, it is convenient for the fragments on the receiving plate 2 to fall off from the receiving plate 2. During the falling process of the fragments, the receiving plate 2 is rotated so that the receiving plate 2 runs on the workbench 12. When the receiving plate 2 is running, the second rod body 102 is adsorbed on the first rod body 101, thus facilitating the guiding of the running of the receiving plate 2.

[0028] Refer to Figure 8 and Figure 9 , in the embodiment of the present application, the connecting member 17 includes a sleeve 171 sleeved on the first rod body 101. A guiding strip 172 protrudes from the inner wall of the sleeve 171. A plurality of clamping grooves 173 for the guiding strip 172 to be clamped are formed on the outer wall of the second rod body 102. A plurality of clamping grooves 173 are provided and are evenly arranged circumferentially along the outer wall of the second rod body 102; when the second rod body 102 and the first rod body 101 are connected, the sleeve 171 is slid so that the guiding strip 172 in the sleeve 171 is clamped in the clamping groove 173, thereby relatively fixing the second rod body 102 and the first rod body 101, thus facilitating the first rod body 101 to drive the second rod body 102 to rotate.

[0029] Refer to Figure 1 and Figure 10, when the test block is damaged by the lower pressing plate 14, the test block falls on the receiving plate 2, and some test blocks will fall from the receiving plate 2 onto the workbench 12 and the ground, resulting in a relatively chaotic test environment. Therefore, in the embodiment of the present application, a socket cover 18 is provided on the receiving plate 2. The socket cover 18 is sleeved on the placing notch 3. Both ends of the socket cover 18 are open and rectangular. The socket cover 18 is frustum-shaped with a gradually decreasing diameter. The circumference of the free end of the socket cover 18 is smaller than the circumference of the test block and is sleeved on the test block. The socket cover 18 is made of an elastic material and is sleeved on the side wall of the test block near the compressed end; when the test block is placed on the receiving block 41, pull the opening of the socket cover 18 to make the opening of the socket cover 18 larger than the test block, and then move the test block into the socket cover 18 from the opening of the socket cover 18 and place it on the receiving block 41. At this time, the opening of the socket cover 18 is close to the end of the test block. When the lower pressing plate 14 tests the test block, the test block breaks inside the socket cover 18, and the broken pieces are located inside the socket cover 18. Under the action of the socket cover 18, the broken pieces are limited, reducing the possibility of the broken pieces falling.

[0030] Refer to Figure 1 and Figure 10 , to facilitate the test block to move into the socket cover 18 from the opening of the socket cover 18, a rectangular frame 19 is provided inside the socket port of the socket cover 18. The frame of the rectangular frame 19 is made of telescopic rods, and a spring is provided inside to drive the telescopic rods to retract; when the test block moves into the socket cover 18 from the opening of the socket cover 18, pull the corners of the rectangular frame 19, and the frame of the rectangular frame 19 extends to expand the opening of the socket cover 18, thus facilitating the test block to move into the socket cover 18.

[0031] The implementation principle of the pressing device for testing raw materials in highway engineering in the embodiment of the present application is as follows: When testing the strength of the test block, first place the test block on the receiving plate 2. After the test block is on the receiving plate 2, pull the corners of the rectangular frame 19, and the frame of the rectangular frame 19 extends to expand the opening of the socket cover 18, and then move the test block into the socket cover 18 cup; the test block is in the placing notch 3 and the first push rod 42 is started. The first push rod 42 drives the receiving block 41 to slide out of the chute 6 and then places the test block on the receiving block 41; then the second push rod 52 is started. The second push rod 52 drives the positioning rod 51 to slide. After the positioning rod 51 moves out of the placing notch 3, it abuts against the test block, so that the test block is located in the middle of the placing notch 3; Then the hydraulic cylinder 16 is started. The hydraulic cylinder 16 drives the lower pressing plate 14 to slide and press the test block to perform the strength test of the test block; when the test block breaks, the first push rod 42 is started. The first push rod 42 pushes the receiving block 41 to slide out of the chute 6. Since the receiving block 41 abuts on the test bench 13 and the end face of the receiving block 41 is inclined, when the two receiving blocks 41 approach each other, the broken pieces on the test bench 13 are shoveled, and the broken pieces are transferred from the test bench 13 to the receiving block 41; Subsequently, rotate the receiving plate 2 to replace the test block to be tested. When replacing the test block, the receiving plate 2 scrapes the fragments on the test bench 13, and some of them fall on the workbench 12. After the installation cavity 7 moves to the test bench 13, start the first motor 9, and the first motor 9 drives the brush rod 8 to rotate. When the brush rod 8 rotates, the bristles on the brush rod 8 remove the fine impurities on the test bench 13, so that the test bench 13 is relatively clean and convenient for the test block to fall on the test bench 13. Rotate the receiving plate 2 again, and the receiving plate 2 drives the adjacent test block onto the test bench 13, thus reducing the process of installing the test block and improving the test efficiency of the test block.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
