Description

Technical Field

[0001] This application relates to the field of materials testing technology, and in particular to a device for testing the strength of cement concrete structures. Background Technology

[0002] As a core material in modern construction engineering, cement concrete's strength directly determines the safety, durability, and service life of buildings, bridges, roads, and other engineering structures. In road construction, insufficient concrete pavement strength can lead to cracking, subsidence, and other problems, seriously affecting traffic safety.

[0003] Therefore, accurate and efficient testing of the strength of cement concrete structures is a crucial step in ensuring project quality and preventing safety accidents. Generally, cement is mixed according to a specific ratio, and after it solidifies into brick-like blocks, these blocks are placed on a pressure sensor. A hydraulic rod applies pressure to the blocks, and the strength is determined based on the sensor reading. However, current testing methods still have the following problems:

[0004] 1. After performing strength testing on cement concrete, the existing strength testing equipment leaves a large number of concrete fragments on the test platform that need to be cleaned. If the fragments are not cleaned before the next test, it will affect the testing of the next piece of cement concrete. The debris may change the position of the fracture surface, resulting in uneven pressure distribution in the cement concrete, which in turn affects the strength test results. The large amount of debris requires manual cleaning, which increases cleaning time and labor costs and affects the efficiency of cement concrete structural strength testing.

[0005] 2. During the strength testing of cement bricks, in order to prevent the cement bricks from breaking and scattering fragments, baffles are usually used to surround the cement bricks for protection. However, the existing baffles are all fixedly installed, so they do not have a buffering effect on the splashed concrete fragments. When the fragments hit, there is a risk of secondary splashing, which may cause injury to the surrounding personnel and equipment, and there is also a lot of noise when they come into contact with the baffles.

[0017] The technical solution provided in this application has at least the following technical effects or advantages:

[0018] 1. By employing a support component, this invention effectively solves the problem of existing strength testing devices leaving a large amount of concrete debris on the platform after cement concrete strength testing, which requires cleaning. If the debris is not cleaned before the next test, it affects the testing of the next piece of cement concrete. The debris may alter the fracture surface, causing uneven pressure distribution in the cement concrete, thus affecting the strength test results. Manual cleaning of a large amount of debris increases cleaning time and labor costs, affecting the efficiency of cement concrete structure strength testing. This invention, through its support component, maintains a stable and horizontal support platform during the testing of cement concrete bricks. After the test, the support platform can reciprocate and shake, automatically cleaning the debris on the platform surface, thus keeping the platform clean and facilitating the testing of the next piece of cement concrete. This keeps the cement concrete on the platform stable, resulting in uniform pressure distribution during testing, improving the accuracy of concrete structure strength testing, saving manual cleaning time and labor costs, and increasing the efficiency of cement concrete structure strength testing.

[0019] 2. By employing protective components, this invention effectively solves the problem of secondary splashing of cement bricks during strength testing. Existing baffles, which are fixed in place, do not buffer the impact of flying concrete fragments. This increases the risk of secondary splashing and injury to personnel and equipment, and generates significant noise upon contact with the baffle. The protective components of this invention effectively shield the flying debris, providing a buffering effect through flexible shielding. This prevents secondary splashing between the fragments and the shield, protecting workers and equipment from damage, and reducing noise during impact. Attached Figure Description

[0034] After testing the strength of cement concrete, a large number of concrete fragments on the platform need to be cleaned. This invention uses a support component to keep the support platform stable and level during the testing of cement concrete bricks. After the test is completed, the support platform can reciprocate and shake, automatically cleaning the fragments on the support platform. Existing baffles are all fixed and therefore do not have a buffering effect on the splashed concrete fragments. This invention uses a protective component to shield the splashed debris, and the flexible shielding method provides a buffering effect on the splashed debris, thereby preventing secondary splashing between the fragments and the shielding material.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] Example 1:

[0037] Please see Figure 1 and Figure 2As shown, a cement concrete structure strength testing device includes a testing body 1 and a hydraulic cylinder 2. The hydraulic cylinder 2 is fixedly installed on the top and bottom walls of the testing body 1. A hydraulic rod 3 is slidably connected to the inner cavity of the hydraulic cylinder 2. A testing disc 4 is fixedly installed at the bottom end of the hydraulic rod 3. A support assembly 5 and a protective assembly 6 are provided in the inner cavity of the testing body 1. The cement concrete bricks to be tested are placed on the support assembly 5. The operation of the hydraulic cylinder 2 drives the hydraulic rod 3 to move downward. The downward movement of the hydraulic rod 3 causes the testing disc 4 to squeeze the cement concrete bricks, which facilitates the strength testing of the cement concrete bricks. The support assembly 5 can clean up the concrete fragments after testing, which facilitates continuous testing of cement concrete bricks. The protective assembly 6 can prevent fragments from flying everywhere during testing and prevent flying fragments from injuring the staff.

[0038] Please see Figure 2 and Figure 3 As shown, the support assembly 5 includes a base plate 51, a rocking mechanism 52 is provided on the upper surface of the base plate 51, a support mechanism 53 is provided above the rocking mechanism 52, a power mechanism 54 is provided on the outer surface of the rocking mechanism 52, a limit mechanism 55 is provided above the power mechanism 54, and a dust removal mechanism 56 is provided on the inner wall of the protective assembly 6. When the strength of the cement concrete bricks is tested, the downward movement of the hydraulic rod 3 drives the limit mechanism 55 to move downward. At this time, the support mechanism 53 can be kept horizontal and at a constant temperature, so that the cement concrete bricks on the upper surface of the support mechanism 53 and the testing plate 4 are in uniform contact, which facilitates the testing of the strength of the cement concrete bricks. When the limit mechanism 55 moves upward, the power mechanism 54 drives the rocking mechanism 52 to shake, thereby causing the support mechanism 53 to swing, causing the cement concrete fragments on the upper surface of the support mechanism 53 to fall off. With the blowing of the dust removal mechanism 56, the upper surface of the support mechanism 53 is cleaned, making it easy to reuse.

[0039] Please see Figures 4-9As shown, the rocking mechanism 52 includes a support frame 521. A rocking rod 522 is rotatably connected to the inner cavity of the support frame 521. Support grippers 523 are fixedly connected to both ends of the rocking rod 522. A fixing ring 524 is fixedly connected to the middle part of the rocking rod 522. A rocking bar 525 is fixedly connected to the lower part of the fixing ring 524. A drive rod 526 is slidably connected to the inner cavity of the rocking bar 525. A drive block 527 is fixedly connected to one end of the drive rod 526. A rotating rod 528 is rotatably connected to the inner cavity of the support frame 521. The rotating rod 528 and the drive block 527 are fixedly connected. The drive block 527 and the support frame 521 are rotatably connected. The support frame 521 is fixedly connected to the base plate 51. The support mechanism 53 includes a support platform 531. The support platform 531 is equipped with... A pressure sensor is included, and the pressure sensor is electrically connected to the detection body 1 to facilitate the collection of pressure data experienced by the brick during the extrusion process. A limit rod 532 is fixedly installed on the outer surface of the support platform 531, and a limit strip 533 is fixedly installed on the upper surface of the support platform 531. A threaded rod 534 is rotatably connected to the inner cavity of the limit strip 533, and a clamping block 535 is slidably connected to the outer surface of the limit strip 533. The clamping block 535 and the limit rod 532 are slidably connected, and the clamping block 535 and the threaded rod 534 are connected by threads, with the threads at both ends of the threaded rod 534 having opposite directions. A baffle plate 536 is fixedly connected to one end of the clamping block 535. The support platform 531 is located directly below the detection disk 4, and the middle part from the limit strip 533 to the support platform 531 is hollowed out. The limiting rod 532 and the limiting strip 533 have gaps to the upper surface of the support platform 531, which facilitates the falling of debris from the support platform 531 during swinging motion. The support platform 531 and the support gripper 523 are fixedly connected. The power mechanism 54 includes a moving block 541, which is slidably connected to the outer surface of the support frame 521. A fixing block 542 is fixedly installed on the surface of the support frame 521. A rack 543 is fixedly connected to one side of the moving block 541. A first sliding rod 544 is fixedly connected to the inner cavity of the rack 543. A first spring 545 is sleeved on the outer surface of the first sliding rod 544. The rack 543 and the fixing block 542 are slidably connected. The first sliding rod 544 is located on the inner wall of the rack 543 and the fixing block 542. Between 42, a positioning mechanism 546 is provided on the outer surface of the movable block 541. A first gear 547 is fixedly connected to the surface of the rotating rod 528. The first gear 547 meshes with the rack 543. A connecting groove 548 is opened on the outer surface of the movable block 541. The positioning mechanism 546 includes a positioning frame 5461. A positioning rod 5462 is slidably connected to the inner cavity of the positioning frame 5461. A ball 5463 is rollably connected to one end of the positioning rod 5462. A first slider 5464 is fixedly connected to the outer surface of the positioning rod 5462. A second spring 5465 is sleeved on one end of the positioning rod 5462. The second spring 5465 is located between the inner wall of the positioning frame 5461 and the first slider 5464. The first slider 5464 and the positioning frame 5461 are slidably connected.The outer surfaces of the positioning frame 5461 and the moving block 541 are fixedly connected. The limiting mechanism 55 includes a connecting sleeve 551, which is fixedly connected to the bottom end of the hydraulic rod 3. A storage rod 552 is fixedly connected to the lower surface of the connecting sleeve 551. A telescopic rod 553 is slidably connected to the inner cavity of the storage rod 552. A first connecting block 554 is fixedly installed on the outer surface of the storage rod 552. An adjusting rod 555 is rotatably connected to the inner cavity of the first connecting block 554 via a thread. A first spring 545 is kept in a natural state on the first sliding rod 544. A positioning hole 556 is opened at the bottom end of the telescopic rod 553. The bottom end of the positioning hole 556 is chamfered. A storage groove 557 is opened at the lower end of the storage rod 552. The upper end of the telescopic rod 553 slides with the storage groove 557. The support frame 521 has a slot 558 on one side. A second slider 559 is slidably connected to the inner cavity of the support platform 531. A rod 5510 is fixedly installed on the lower surface of the second slider 559. A third spring 5511 is sleeved on the outer surface of the rod 5510. The third spring 5511 is located between the second slider 559 and the inner wall of the support platform 531. The rod 5510 and the support platform 531 are slidably connected. When the second slider 559 moves down, the rod 5510 engages with the slot 558. The adjusting rod 555 is located directly above the second slider 559. When the detection disc 4 moves down, the telescopic rod 553 engages with the connecting groove 548. At this time, the positioning hole 556 and the ball 5463 engage. Simultaneously, the adjusting rod 555 presses against the second slider 559. When testing cement concrete bricks, the threaded rod 534 is rotated according to the size of the brick, causing the clamping block 535 to move on the limiting strip 533 and the limiting rod 532. The brick is placed on the upper surface of the support platform 531, so that the clamping block 535 clamps and fixes the brick. The baffle plate 536 is used to block and prevent broken debris from entering the inner cavity of the limiting strip 533 and affecting the transmission of the threaded rod 534. The threaded rod 534 can adjust the distance between the two clamping blocks 535 within a certain range, which is convenient for strength testing of bricks of various specifications. When the hydraulic cylinder 2 works and drives the hydraulic rod 3 to move downward, the connecting sleeve 551 moves downward along with the hydraulic rod 3, causing the storage rod 552 to move downward. The downward movement of the storage rod 552 causes the telescopic rod 553 to move downward. The downward movement of the storage rod 552 simultaneously drives the first... When the first connecting block 554 moves downward, the adjusting rod 555 presses against the second slider 559. The compression of the second slider 559 causes the insert rod 5510 to press against the third spring 5511. At this time, the insert rod 5510 passes through the slot 558 on the support platform 531 and the support frame 521 and engages, thus keeping the support platform 531 and the support frame 521 relatively fixed. At this time, the support platform 531 remains horizontal and provides stable support for the brick. Meanwhile, when the telescopic rod 553 moves downward, it is located in the inner cavity of the connecting groove 548. The bottom end of the telescopic rod 553 presses against the ball 5463, causing the positioning rod 5462 to slide in the inner cavity of the positioning frame 5461. Under the elastic force of the second spring 5465, the positioning hole 556 and the ball 5463 engage.At this time, the upper end of the telescopic rod 553 slides in the inner cavity of the receiving groove 557 and is partially housed in the inner cavity of the receiving rod 552 at the middle part of the inner cavity of the receiving groove 557. When the hydraulic cylinder 2 drives the hydraulic rod 3 to retract, the upward movement of the hydraulic rod 3 causes the connecting sleeve 551 to move upward, the upward movement of the connecting sleeve 551 causes the receiving rod 552 to move upward, the upward movement of the receiving rod 552 causes the first connecting block 554 to move upward, the upward movement of the first connecting block 554 causes the adjusting rod 555 to move upward, and the upward movement of the adjusting rod 555 causes the adjusting rod 555 to disengage from the pressure on the second slider 559. At this time, the elastic force of the third spring 5511 causes the insertion rod 5510 to move upward, thereby... The insertion rod 5510 disengages from the slot 558, freeing the support platform 531. Since the ball bearing 5463 engages with the positioning hole 556 to move the moving block 541 upwards, the telescopic rod 553 remains fixed relative to the moving block 541 as the storage rod 552 moves upwards. At this time, the telescopic rod 553 moves within the cavity of the storage groove 557. When the telescopic rod 553 reaches the lowest point of the storage groove 557, the upward movement of the storage rod 552 causes the telescopic rod 553 to move upwards. This upward movement of the telescopic rod 553 then causes the moving block 541 to move upwards. The upward movement of the moving block 541 causes the rack 543 to move upwards, which in turn causes the first gear 547 to rotate. The rotation of wheel 547 drives the rotating rod 528 to rotate, which in turn drives the drive block 527 to rotate. The rotation of drive block 527 drives the drive rod 526 to rotate, which in turn drives the rocker bar 525 to swing. The swinging of the rocker bar 525 drives the fixed ring 524 to rotate, which in turn drives the rocker arm 522 to reciprocate within the support frame 521. The rotation of the rocker arm 522 drives the support gripper 523 to swing back and forth, which in turn drives the support platform 531 to swing. This causes the support platform 531 to swing back and forth, causing debris to fall from the upper surface of the support platform 531. The upward-moving fixed block 542 of the moving block 541 increases the squeezing force on the first spring 545, thereby stopping the moving block 541 from moving upward. At this time, the ball 5463 and the positioning hole 556 disengage, causing the telescopic rod 553 to fall out of the inner cavity of the connecting groove 548. The elastic force of the first sliding rod 544 and its own weight drive the moving block 541 back to its original position. At this time, the rack 543 drives the first gear 547 to rotate again, causing the support platform 531 to swing. When the rack 543 contacts the upper surface of the base plate 51, the first gear 547 remains stable, and the support platform 531 remains horizontal, realizing automatic cleaning of debris on the upper surface of the support platform 531 and improving detection efficiency.

[0040] Please see Figure 2 , Figure 3 , Figure 10 and Figure 11As shown, the dust removal mechanism 56 includes a dust removal frame 561. A gear frame 562 is slidably connected to the inner cavity of the dust removal frame 561. A second gear 563 is rotatably connected to the middle part of the outer surface of the dust removal frame 561. Half of the second gear 563 is hollowed out. Fans 564 are rotatably connected to both ends of the gear frame 562. A dust cover 565 is fitted onto the outer surface of the fan 564. The dust cover 565 and the gear frame 562 are fixedly connected. The second gear 563 meshes with the gear frame 562. A second connecting block 566 is fixedly connected to the outer surface of the dust removal frame 561. A motor 567 is installed in the middle part of the outer surface of the dust removal frame 561. The output end of the motor 567 is fitted onto the second gear 563. The operation of the motor 567 drives the second gear 563 to rotate. The rotation of the second gear 563 drives the gear frame 562 to reciprocate within the inner wall of the dust removal frame 561. The reciprocating movement of the gear frame 562 drives the fan 564 to reciprocate, thereby blowing the upper surface of the support platform 531, facilitating the removal of debris from the upper surface of the support platform 531. Combined with the oscillation of the support platform 531, this better cleans the debris on its upper surface. The dust cover 565 protects the fan 564. The second connecting block 566 and the connecting plate 62 adjust the angle of the fan 564 relative to the support platform 531, allowing the fan 564 to blow debris from the upper surface of the support platform 531 when it oscillates, improving the cleaning effect and ensuring the upper surface of the support platform 531 remains clean during subsequent tests. This ensures that the cement concrete bricks remain stable during each test, resulting in uniform stress on the cement concrete bricks and improving the accuracy of the strength test data.

[0041] Example 2:

[0042] Please see Figure 2 and Figure 12 As shown, the protective component 6 includes a protective barrel 61, a connecting plate 62 fixedly installed on the inner wall of the protective barrel 61, a support column 63 fixedly connected to the inner cavity of the detection body 1, a protective mechanism 64 provided on the upper surface of the support column 63, a buffer plate 65 slidably connected to the inner cavity of the protective barrel 61, a limit bolt 66 fixedly connected to the bottom wall of the protective barrel 61, a fifth spring 67 sleeved on the outer surface of the limit bolt 66, and a support plate 68 provided on the upper surface of the protective mechanism 64. The protective barrel 61 shields the flying debris, and the protective mechanism... The flexible connection 64 between the support column 63 and the support plate 68 allows the protective barrel 61 to be flexibly connected to the inner cavity of the detection body 1, thereby buffering the flying debris and reducing the force of the secondary rebound of the flying debris. At the same time, when the cement concrete bricks are crushed and fall onto the buffer plate 65, they compress the fifth spring 67, causing the buffer plate 65 to slide on the limit bolt 66, thereby reducing the damage to the buffer plate 65 and the overall equipment caused by the debris, and also reducing the noise generated by the contact between the debris and the protective barrel 61 and the buffer plate 65.

[0043] Please see Figure 12 and Figure 13 As shown, the protective mechanism 64 includes a connecting rod 641, a second sliding rod 642 fixedly mounted on the outer surface of the connecting rod 641, a fourth spring 643 sleeved on the outer surface of the second sliding rod 642, a washer 644 slidably connected to the outer surface of the second sliding rod 642, a floating ring 645 movably connected between the support column 63 and the support plate 68, a buffer groove 646 formed on the outer surface of the floating ring 645, a fifth spring 67 located between the protective barrel 61 and the buffer plate 65, a connecting plate 62 and a second connecting block 566 rotatably connected, an upper surface of the support plate 68 and a lower surface of the base plate 51 fixedly connected, a buffer plate 65 located below the base plate 51, a connecting rod 641 fixedly connected to both the support column 63 and the support plate 68, and a second sliding rod 642 located between the connecting rod 641 and the washer 644. To prevent the inner walls of the fourth spring 643 and the floating ring 645 from rubbing against each other, the second slide rod 642 and the buffer groove 646 are slidably connected, and the floating ring 645 and the protective barrel 61 are fixedly connected. The buffer plate 65 is located between the support column 63 and the support plate 68. When the flying fragments come into contact with the protective barrel 61, they will impact the protective barrel 61. At this time, the protective barrel 61 will cause the floating ring 645 to shake between the support column 63 and the support plate 68. The shaking of the floating ring 645 will cause the pad 644 to squeeze the fourth spring 643. At this time, the second slide rod 642 will slide in the inner cavity of the buffer groove 646. That is, the protective barrel 61 is flexibly connected between the support column 63 and the support plate 68, which can reduce the damage caused by the impact of flying fragments on the protective barrel 61 and facilitate the rapid recovery of vibration and noise reduction of the protective barrel 61 after impact.

[0044] In summary, the cement concrete bricks requiring strength testing are placed on the support assembly 5. The hydraulic cylinder 2 drives the hydraulic rod 3 downwards, which in turn causes the testing disc 4 to press against the cement concrete bricks, facilitating strength testing. The support assembly 5 can clean up concrete fragments after testing, allowing for continuous testing. The protective assembly 6 prevents fragments from flying everywhere during testing, protecting workers from injury. During strength testing, the downward movement of the hydraulic rod 3 causes the limiting mechanism 55 to move downwards, keeping the support assembly 53 horizontal and at a suitable temperature. This ensures uniform contact between the cement concrete bricks on the upper surface of the support assembly 53 and the testing disc 4, facilitating strength testing. When the limiting mechanism 55 moves upwards, the power mechanism 54... The shaking mechanism 52 shakes, causing the support mechanism 53 to sway, which in turn causes cement concrete fragments on the upper surface of the support mechanism 53 to fall off. Combined with the blowing of the dust removal mechanism 56, the upper surface of the support mechanism 53 is cleaned for reuse. The protective barrel 61 shields the flying debris. The protective mechanism 64 is flexibly connected between the support column 63 and the support plate 68, and the protective barrel 61 is flexibly connected to the inner cavity of the detection body 1. This can buffer the flying debris and reduce the force of the secondary rebound of the flying fragments. At the same time, when the cement concrete bricks are crushed and fall onto the buffer plate 65, they compress the fifth spring 67, causing the buffer plate 65 to slide on the limit bolt 66, thereby reducing the damage to the buffer plate 65 and the overall equipment caused by the fragments. It also reduces the noise generated by the fragments contacting the protective barrel 61 and the buffer plate 65.
