Description

Technical Field

[0001] This application relates to the field of concrete testing, and in particular to an environmentally friendly concrete durability testing device and its testing method. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. Ordinary concrete refers to cement concrete made by mixing cement as cementing material, sand (also known as fine aggregate) and stone (also known as coarse aggregate) as aggregates, and water (which may contain admixtures and additives) in a certain proportion. After solidification, it has a certain hardness and strength. Concrete durability is one of the important indicators for testing concrete quality. After concrete production, its durability performance usually needs to be tested.

[0003] Existing concrete durability testing instruments typically include a test platform and a press. When testing the durability of concrete, a concrete block is first placed on the test platform, and pressure is applied to the concrete block using the press. The durability of the concrete block is determined based on the magnitude of the pressure it experiences when it fails. After testing one set of concrete blocks, the test platform is cleaned before placing another set of concrete blocks for testing.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: after a set of concrete blocks has been tested, the concrete blocks need to be manually removed from the test platform and replaced with concrete blocks of different materials for testing. The replacement of concrete blocks needs to be done at the bottom of the press, which poses certain safety hazards. Summary of the Invention

[0005] To improve the safety of concrete durability testing instruments when testing concrete blocks, this application provides an environmentally friendly concrete durability testing device and its testing method.

[0006] This application provides an environmentally friendly concrete durability testing device, which adopts the following technical solution:

[0007] An environmentally friendly concrete durability testing device includes a test platform and a press mounted on the test platform. The test platform is characterized by having a testing table for testing concrete blocks, a placement rack, and a feeding mechanism. The feeding mechanism includes a feeding track and a driving component for moving concrete blocks from the feeding track to the testing table. The placement rack has multiple placement slots for placing concrete blocks to be tested, and these slots are connected to the feeding track. The placement rack also has a pushing component for pushing the concrete blocks from the placement slots into the feeding track.

[0008] By adopting the above technical solution, when the device tests concrete blocks, multiple concrete blocks are first placed in the placement slots on the placement frame. The pushing component pushes the concrete blocks in the placement slots into the feeding track. Then, the driving component pushes the concrete blocks in the feeding track onto the testing platform. There is no need for manual replacement of the concrete blocks during testing, making it safer to use.

[0009] Optionally, the drive assembly includes a push block, a threaded rod, and a drive motor. The push block is slidably disposed within the feeding track, and the threaded rod is rotatably connected to the feeding track. The axial direction of the threaded rod is the same as the sliding direction of the push block. The threaded rod passes through the push block and is threadedly connected to the push block. The threaded rod is coaxially disposed on the output shaft of the drive motor, and the drive motor is disposed on the test platform.

[0010] By adopting the above technical solution, after the concrete block enters the feeding track, the drive motor is started to drive the threaded rod to rotate. The rotation of the threaded rod drives the pusher block to move within the feeding track. The pusher block pushes the concrete block to move onto the testing platform. There is no need for manual placement, making it safe to use and more accurate in placement.

[0011] Optionally, a telescopic plate is provided on the side of the feeding track near the placement frame. The telescopic plate extends in the same direction as the sliding direction of the push block. One end of the telescopic plate is connected to the feeding track, and the other end of the telescopic plate is connected to the push block.

[0012] By adopting the above technical solution, the telescopic plate extends or retracts with the movement of the pusher block. The telescopic plate blocks the connection between the feeding track and the placement trough, so that only one concrete block enters the feeding track at a time, which makes it easier to push the concrete block to the testing platform for testing.

[0013] Optionally, the pushing assembly includes a first spring and a push plate, the push plate being slidably disposed inside the placement groove, one end of the first spring being connected to the push plate, the other end of the first spring being connected to the placement groove, and the push plate being movably abutting against the feeding track.

[0014] By adopting the above technical solution, the first spring pushes the push plate to abut against the feeding track, placing the concrete block in the placement groove. The first spring pushes the push plate to make the concrete block abut against the telescopic plate. When the telescopic plate retracts, the push plate pushes the concrete block into the feeding track. The structure is simple and easy to use.

[0015] Optionally, a protective cover is provided on the testing platform, and openings are provided at the top of the protective cover and on the side near the feeding track.

[0016] By adopting the above technical solution, a protective cover is installed over the testing platform, with openings on the cover to allow concrete blocks and the output shaft of the press to enter, thus preventing concrete blocks from flying debris during testing and improving the safety of the testing.

[0017] Optionally, the output shaft of the press is provided with a pressure plate that movably abuts against the test table, the pressure plate movably passes through the opening at the top of the protective sleeve, and the pressure plate is provided with a sealing component for sealing the opening.

[0018] By adopting the above technical solution, the press drives the pressure plate to squeeze the concrete block to achieve the detection of the concrete block. At the same time, the sealing component seals the opening at the top of the protective sleeve to further prevent the gravel from flying out of the opening, making the detection safer.

[0019] Optionally, the sealing assembly includes a sealing plate and a second spring. The sealing plate is sleeved on the output shaft of the press and movably abuts against the opening at the top of the protective sleeve. One end of the second spring is connected to the pressure plate, and the other end of the second spring is connected to the sealing plate.

[0020] By adopting the above technical solution, after the pressure plate enters the protective cover, the sealing plate seals the opening. At the same time, as the pressure plate continues to descend, the second spring extends, making the sealing plate make closer contact with the opening, and the sealing effect of the opening is better.

[0021] Optionally, the pusher is curved, and the inner wall of the pusher is movably fitted with the outer wall of the protective cover.

[0022] By adopting the above technical solution, after the pusher pushes the concrete block into the protective cover, the drive motor is turned off, so that the inner wall of the pusher fits against the outer wall of the protective cover, thereby sealing the opening on the side wall of the protective cover and preventing the concrete block from flying out of the opening on the side wall of the protective cover during testing.

[0023] Optionally, the test platform is equipped with a collection box, and the test platform has a discharge port communicating with the collection box. The testing platform is rotatably set at the discharge port, and the rotation axis of the testing platform is parallel to the surface of the test platform. The test platform is equipped with a vertically set electric telescopic rod, and the top end of the electric telescopic rod is rotatably connected to the testing platform.

[0024] By adopting the above technical solution, after the concrete block is tested, the electric telescopic rod is activated to drive the testing platform to rotate, and the concrete on the testing platform is poured into the collection box for collection and processing. Then another set of concrete blocks is sent to the testing platform. There is no need to manually clean the concrete blocks on the testing platform, making it more convenient to use.

[0025] This application provides a testing method for an environmentally friendly concrete durability testing device, comprising the following steps:

[0026] Step 1: Adjust the initial position of the pusher block close to the testing table, with the telescopic plate in the extended state. Place different types of concrete blocks into the placement slots on the placement frame, ensuring the concrete blocks contact the telescopic plate.

[0027] Step 2: Start the drive motor to make the pusher move away from the test platform, and at the same time drive the telescopic plate to retract. When a set of concrete blocks in the placement slot enters the feeding track, the drive motor rotates in the opposite direction, causing the pusher to push the concrete blocks onto the test platform.

[0028] Step 3: The press pushes the pressure plate to squeeze and test the concrete block on the testing table, and the sealing plate seals the opening of the protective cover;

[0029] Step 4: After the test is completed, start the electric telescopic rod to rotate the test platform and pour the concrete blocks on the test platform into the collection box for collection and processing.

[0030] In summary, this application includes at least the following beneficial technical effects:

[0031] By setting up a feeding track, drive assembly, placement rack, and push assembly, this device first places multiple concrete blocks into the placement slots on the placement rack when testing concrete blocks. The push assembly then pushes the concrete blocks in the placement slots into the feeding track, and the drive assembly pushes the concrete blocks in the feeding track onto the testing platform. No manual replacement of concrete blocks is required during testing, making it safer to use.

[0032] The first spring pushes the push plate to abut against the feeding track, placing the concrete block in the placement groove. The first spring pushes the push plate to abut against the telescopic plate. When the telescopic plate retracts, the push plate pushes the concrete block into the feeding track. The structure is simple and easy to use.

[0033] After testing a set of concrete blocks, the electric telescopic rod is activated to rotate the testing platform, pouring the concrete on the platform into a collection box for collection and processing. Then, another set of concrete blocks is sent to the testing platform, eliminating the need for manual cleaning of the concrete blocks on the testing platform. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses an environmentally friendly concrete durability testing device.

[0041] Reference Figure 1-3 An environmentally friendly concrete durability testing device includes a test platform 1 and a press 2 fixedly installed on the test platform 1. A test table 3 is set on the test platform 1. When testing a concrete block, the concrete block to be tested is first placed on the test table 3, and the press 2 is started to pressurize the concrete block on the test table 3 until the concrete block breaks.

[0042] Reference Figure 1 , 2 4. To facilitate the movement of concrete blocks to the testing platform 3, a feeding mechanism 5 is provided on the testing platform 1. In this embodiment, the feeding mechanism 5 includes a feeding track 51 and a driving component 52. The feeding track 51 is arranged in a straight line and the testing platform 3 is located at one end of the feeding track 51. When conveying concrete blocks, the concrete blocks are placed on the feeding track 51, and the driving component 52 drives the concrete blocks to move inside the feeding track 51, thereby pushing the concrete blocks to the testing platform 3.

[0043] To enable the concrete blocks to move within the feeding track 51, the drive assembly 52 includes a push block 521, a threaded rod 522, and a drive motor 523. The push block 521 is slidably connected within the feeding track 51, and the threaded rod 522 is rotatably connected to the feeding track 51. The axial direction of the threaded rod 522 is the same as the sliding direction of the push block 521. The threaded rod 522 passes through the push block 521 and is threadedly connected to it. The drive motor 523 is fixedly installed on the test platform 1, and the threaded rod 522 is coaxially fixedly connected to the output shaft of the drive motor 523. After the drive motor 523 is started, it drives the threaded rod 522 to rotate forward or backward, causing the push block 521 to move along the setting direction of the feeding track 51, thereby pushing the concrete blocks on the feeding track 51.

[0044] Reference Figure 1 , 2 To achieve automatic addition of concrete blocks to the feeding track 51, a placement frame 4 is fixedly connected to the test platform 1. The placement frame 4 has multiple placement slots 41, which are connected to the feeding track 51. The placement frame 4 is equipped with a pushing component 42 for pushing the concrete blocks in the placement slots 41 into the feeding track 51. The pushing component 42 includes a first spring 421 and a push plate 422. The push plate 422 is slidably connected to the inside of the placement slot 41. One end of the first spring 421 is fixedly connected to the push plate 422, and the other end of the first spring 421 is fixedly connected to the placement slot 41. The axial direction of the first spring 421 is the same as the sliding direction of the push plate 422. The first spring 421 pushes the push plate 422 to move and abut against the feeding track 51.

[0045] Before testing the concrete blocks, multiple concrete blocks are placed in different placement slots 41. The concrete blocks are moved by the push plate 422. To ensure that the concrete blocks in the multiple placement slots 41 can enter the feeding track 51 in sequence, a telescopic plate 524 is provided on the side of the feeding track 51 near the placement frame 4. One end of the telescopic plate 524 is fixedly connected to the feeding track 51, and the other end is fixedly connected to the push block 521. The telescopic plate 524 extends or retracts with the movement of the push block 521. The telescopic plate 524 blocks the connection between the feeding track 51 and the placement slots 41. When the push block 521 moves away from the testing platform 3, the telescopic plate 524 retracts, opening the connection between the placement slots 41 and the feeding track 51. The push plate 422 pushes the concrete blocks into the feeding track 51 and then drives the push block 521 to move closer to the testing platform 3, delivering the concrete blocks to the testing platform 3.

[0046] Reference Figure 3To facilitate the cleaning of concrete blocks on the testing platform 3, a collection box 7 is placed at the bottom of the testing platform 1. The testing platform 1 has a discharge port 11, which is connected to the collection box 7. The testing platform 3 is rotatably connected to the discharge port 11. The rotation axis of the testing platform 3 is parallel to the surface of the testing platform 1. A vertically installed electric telescopic rod 8 is fixedly installed at the bottom of the testing platform 1, and the top of the electric telescopic rod 8 is rotatably connected to the testing platform 3. After a set of concrete blocks is tested, the electric telescopic rod 8 is activated to push the testing platform 3 to rotate, pouring the concrete on the testing platform 3 into the collection box 7 for collection and processing, and then sending another set of concrete blocks to the testing platform 3.

[0047] Reference Figure 1 , 2 To prevent the danger of flying debris during concrete block testing, a protective cover 6 is fixedly connected to the test platform 1. The protective cover 6 is fitted over the outside of the test platform 3, and openings 61 are provided at the top of the protective cover and on the side near the feeding track 51. A pressure plate 21 is fixedly connected to the output shaft of the press 2, which moves and abuts against the test platform 3. The pressure plate 21 moves through the opening 61 at the top of the protective cover to pressurize and test the concrete blocks on the test platform 3. A sealing component 22 is provided on the pressure plate 21 to seal the opening 61 and prevent debris from flying out of the protective cover. The opening 61 at the top of the protective cover flies out; In this embodiment, the sealing assembly 22 includes a sealing plate 221 and a second spring 222. The sealing plate 221 is sleeved on the output shaft of the press 2, and the second spring 222 is sleeved on the output shaft of the press 2 and located between the sealing plate 221 and the pressure plate 21. One end of the second spring 222 is fixedly connected to the pressure plate 21, and the other end of the second spring 222 is fixedly connected to the sealing plate 221. After the output shaft of the press 2 extends into the interior of the protective cover 6, the sealing plate 221 abuts against the opening 61 at the top of the protective cover.

[0048] To prevent gravel from flying out of the opening 61 on the side wall of the protective cover 6, the push block 521 is curved. After the push block 521 pushes the concrete block to the test platform 3, the inner wall of the push block 521 fits against the outer wall of the protective cover 6, sealing the opening 61 on the side wall of the protective cover 6.

[0049] This application also discloses a testing method for an environmentally friendly concrete durability testing device.

[0050] A testing method for an environmentally friendly concrete durability testing device includes the following steps:

[0051] Step 1: Adjust the initial position of the push block 521 to be close to the test table 3, and the telescopic plate 524 is in the extended state. Place different types of concrete blocks into the placement slot 41 on the placement frame 4, and the concrete blocks abut against the telescopic plate 524.

[0052] Step 2: Start the drive motor 523 to make the push block 521 move away from the test platform 3, and at the same time drive the telescopic plate 524 to retract. When a set of concrete blocks in the placement slot 41 enters the feeding track 51, the drive motor 523 rotates in the opposite direction, so that the push block 521 pushes the concrete block onto the test platform 3.

[0053] Step 3: Press 2 pushes the pressure plate 21 to squeeze and test the concrete block on the test table 3, and sealing plate 221 seals the opening 61 of the protective cover 6;

[0054] Step 4: After the test is completed, start the electric telescopic rod 8 to push the test platform 3 to rotate, so that the concrete blocks on the test platform 3 can be poured into the collection box 7 for collection and processing.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
