Description

Technical Field

[0001] This application relates to the technical field of concrete testing, and in particular to a concrete testing and inspection device and its usage method. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. Concrete is one of the most important engineering materials in modern times. Concrete test blocks are used to reflect the construction quality of concrete structures, and the compressive strength of concrete test blocks is a key indicator of the construction quality of concrete in a project. Typically, 30 100mm × 100mm × 100mm concrete test blocks are molded simultaneously according to the same mix proportion.

[0003] Currently, a building concrete testing device with publication number CN216847268U includes a base, two sliding grooves symmetrically distributed on the top of the base, four first fixing holes evenly and symmetrically distributed on the top of the base, and two support plates symmetrically distributed on the top of the base. A top plate is fixedly connected to the top of the two support plates.

[0004] However, when testing building concrete, multiple concrete test blocks are usually tested. The aforementioned concrete testing equipment requires repeated removal and installation of the collection component when testing multiple concrete test blocks. During installation, the first and second fixing holes need to be aligned, and then fixed by inserting positioning pins into the first and second fixing holes. This process is cumbersome and affects the efficiency of concrete test block testing. Summary of the Invention

[0005] To improve the efficiency of concrete test block testing, this application provides a concrete testing and inspection device and its usage method.

[0006] The concrete testing and inspection equipment and its usage method provided in this application adopt the following technical solution:

[0007] A concrete testing and inspection device, comprising:

[0008] The machine body is used to place on the ground, and a pressurization component is installed on the machine body for pressurizing and testing concrete test blocks;

[0009] A conveying platform is located on the side of the machine body where the pressurizing component is installed, and the conveying platform is equipped with a transmission component and a positioning component;

[0010] A carrier box, slidably connected to the conveying platform, is used to hold concrete test blocks for testing; a transmission assembly is used to pull the carrier box to move; a positioning assembly is disposed on the path of the carrier box's movement, and the positioning assembly is used to automatically position the carrier box; and

[0011] An unlocking component is installed on the machine body. The unlocking component is used to release the positioning component from locking the carrier box. The unlocking component works in conjunction with the pressurizing component. When the pressurizing component rises, the pressurizing component controls the unlocking component to release the lock on the carrier box.

[0012] By adopting the above technical solution, the carrier box containing the concrete test block is placed on the conveying platform. The transmission component drives the carrier box to move. When the carrier box moves to the positioning component, the positioning component locks the carrier box. The positioning component locks the carrier box and positions it at the same time, which facilitates the pressure component to perform strength testing on the concrete test block.

[0013] After the strength test is completed, the unlocking component is used to unlock the positioning component, so that the transmission component moves the tested carrier box to the other end of the conveyor platform, making it easier to move the next set of carrier boxes to the bottom of the pressurizing component for pressurization test.

[0014] By coordinating the unlocking, transmission, and positioning components, the carrier box can be accurately positioned in the test area of ​​the pressurization component after being installed on the conveyor platform from one end. It is also easy to move the carrier box to the other end, facilitating continuous testing without the need for cumbersome disassembly and positioning operations, thereby improving the efficiency of concrete block testing.

[0015] Optionally, a limiting hole is provided on the conveying platform, and the positioning component is located in the limiting hole. The positioning component includes a spring and a locking block. One end of the spring is fixedly connected to the conveying platform, and the other end is fixedly connected to the locking block. The locking block is inserted into the limiting hole.

[0016] The bottom of the carrier box is provided with a guide groove, which is inclined. The snap-fit ​​block is provided with a guide slope. During the movement of the carrier box, the guide groove abuts against the guide slope on the snap-fit ​​block.

[0017] By adopting the above technical solution, when the carrier box moves toward the snap-fit ​​block, the snap-fit ​​block is stably inserted into the carrier box by the guidance of the guide groove and the compression of the spring, thereby positioning the carrier box.

[0018] Optionally, the carrier box includes a carrier box body, the upper end of the carrier box body is open, the bottom of the carrier box body is provided with a positioning hole, the positioning hole is for the snap-fit ​​block to pass through, the positioning hole is connected to the guide groove, and the bottom of the carrier box body is also connected with a friction pad, the friction pad is in contact with the transmission component.

[0019] By adopting the above technical solution, the movement of the carrier box is achieved by the contact between the friction pad and the transmission component. When the positioning hole moves to match the snap-fit ​​block, the snap-fit ​​block is inserted into the positioning hole, thereby achieving the positioning of the carrier box.

[0020] Optionally, a movable rod is fixedly connected to the friction pad, and a movable groove is provided inside the bearing box. The movable groove is vertically arranged and communicates with the positioning hole. The movable rod passes through the movable groove into the positioning hole.

[0021] By adopting the above technical solution, when the locking block is inserted into the positioning hole, the locking block lifts the moving rod, which in turn moves the friction pad upward, thereby disengaging the friction pad from the transmission assembly. This reduces the friction between the friction pad and the transmission assembly, resulting in a more stable locking of the locking block onto the carrier box.

[0022] Optionally, the conveying platform is provided with a guide groove, and the bottom of the bearing box is provided with guide wheels, which are inserted into the guide groove.

[0023] By adopting the above technical solution, the carrier box can move along the length of the guide groove, which facilitates the locking of the carrier box by inserting the snap-fit ​​block into the positioning hole.

[0024] Optionally, an electromagnet is fixedly connected to the conveying platform, the electromagnet is located at the bottom end of the limiting hole, and the unlocking component includes an unlocking seat and an unlocking handle. The unlocking seat is fixedly connected to the machine body, and the unlocking handle is rotatably connected to the unlocking seat.

[0025] By adopting the above technical solution, the electromagnet is energized by rotating the unlocking handle in a specific direction.

[0026] Optionally, a reset torsion spring is connected between the unlocking seat and the unlocking grip.

[0027] By adopting the above technical solution, the reset torsion spring resets the unlocking grip, so that the electromagnet is de-energized in its natural state.

[0028] Optionally, the pressurizing component includes a pressurizing head. When the pressurizing head moves upward, it abuts against the unlocking handle, at which point the electromagnet is energized. When the pressurizing head continues to move, it disengages from the unlocking handle.

[0029] By adopting the above technical solution, the electromagnet is controlled by the contact between the pressure head and the unlocking handle, thereby simplifying the operation of the carrier box and enabling the movement of the carrier box.

[0030] Optionally, the positioning components are provided in three sets, which are arranged along the transmission component, with the middle set of positioning components located below the pressurizing component.

[0031] By adopting the above technical solution, the three sets of positioning components correspond to the carrier box to be tested, the carrier box under test, and the carrier box after test, respectively, which facilitates the placement and removal of the carrier box.

[0032] This application also discloses a method for using a concrete testing and inspection device, including the following steps:

[0033] S1. Filling the test block: Place the concrete test block in the bearing box and proceed to S2.

[0034] S2. Install the carrier box and place it on the conveying platform, then proceed to S3.

[0035] S3. Control unlocking: Control the unlocking component to release the lock on the carrier box placed on the conveying platform. The carrier box is driven by the transmission component to move to the next positioning component. At this time, the next positioning component locks the carrier box again. S4.

[0036] S4. Control the pressurization. Control the pressurization component to perform a pressurization test on the concrete test block located in the bearing box. S1 can be performed simultaneously during the pressurization test, followed by S5.

[0037] S5, Control the retraction, control the retraction of the pressurizing component. During the retraction of the pressurizing component, S3 will be performed, followed by S6.

[0038] S6. Read the parameters and view the parameters of the pressurization component for testing the concrete test block, and then proceed to S7;

[0039] S7. Clean the bearing box and clean the concrete test block after testing, then proceed with S1.

[0040] By adopting the above technical solution, the method of using a concrete testing and inspection equipment is as follows: filling test blocks → installing the bearing box → controlling unlocking → controlling pressurization → controlling retraction → reading parameters → cleaning the bearing box → filling test blocks.

[0041] The concrete test block is placed in the bearing box, and then the bearing box is placed on the conveying platform. The conveying platform transports the bearing box to the positioning component, which locks the bearing box. Then, the unlocking component is controlled to release the lock on the positioning component, so that the bearing box moves to the next positioning component. The next positioning component locks the bearing box directly below the pressurizing component.

[0042] The pressurizing component is used to test the concrete sample block inside the carrier box. After the test is completed, the pressurizing component is retracted. During the retraction process, the pressurizing component will touch the unlocking component, thereby releasing the positioning component from locking the carrier box. This allows the carrier box to continue moving along the positioning platform to the next positioning component. Then, the carrier box is removed for cleaning.

[0043] During the operation of the pressurization component, the next concrete test block to be tested can be placed in another carrier box, and the next carrier box can be placed on the conveying platform, which facilitates continuous testing of concrete test blocks.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. Through the cooperation of the machine body, pressurizing component, conveying platform, transmission component, positioning component, bearing box, and unlocking component, the placement component is quickly positioned below the pressurizing component, thereby improving the testing efficiency of concrete test blocks;

[0046] 2. By using electromagnets, springs, and locking blocks, the effect of easily locking and unlocking the carrier box is achieved;

[0047] 3. By using the method of filling test blocks → installing the carrier box → controlling unlocking → controlling pressurization → controlling retraction → reading parameters → cleaning the carrier box → filling test blocks, continuous testing of concrete test blocks is achieved, thereby improving the testing efficiency of concrete test blocks.

[0057] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0058] This application discloses a concrete testing and inspection device.

[0059] Reference Figure 1 The concrete testing and inspection equipment includes a body 1 and a pressurizing component 2. A conveying platform 3 is set on one side of the body 1. A positioning component 4 is set on the conveying platform 3. A bearing box 6 is placed on the conveying platform 3. By placing the concrete test block in the bearing box 6, the bearing box 6 is moved on the conveying platform 3. Then, the positioning component 4 locks the bearing box 6, thereby quickly positioning the bearing box 6 under the pressurizing component 2, thus improving the testing efficiency of the concrete test block.

[0060] Reference Figure 2 The conveying platform 3 is also equipped with a transmission assembly 7, which includes a transmission belt 71 and a transmission roller 72. The transmission belt 71 moves along the length of the conveying platform 3 and is provided with anti-slip texture.

[0061] The drive roller 72 drives the drive belt 71 to move on the conveying platform 3. The drive belt 71 contacts the carrier box 6, thereby driving the carrier box 6 to move on the conveying platform 3. The anti-slip texture increases the friction between the carrier box 6 and the drive belt 71.

[0062] Reference Figure 2 The conveying platform 3 is also provided with two guide grooves 31, which are located on both sides of the transmission component 7. The length direction of the two guide grooves 31 is the same as the length direction of the conveying platform 3 and passes through the conveying platform 3.

[0063] The guide groove 31 guides the carrier box 6 so that the carrier box 6 can stably cooperate with the positioning component 4, thereby facilitating the locking of the carrier box 6 by the positioning component 4.

[0064] Reference Figure 1 and Figure 2 The conveying platform 3 is equipped with three sets of positioning components 4. Each set of positioning components 4 includes two positioning components 4, which are located on both sides of the transmission component 7. Each set of positioning components 4 has two guide grooves 31 in the middle. Each set of positioning components 4 can lock the carrier box 6. Different functions can be achieved by locking the carrier box 6 at different positions.

[0065] Reference Figure 2 and Figure 3 The three sets of positioning components 4 are the first set of positioning components 4, the second set of positioning components 4, and the third set of positioning components 4, according to the transmission direction of the conveyor belt. The first set of positioning components 4 is used to limit the carrier box 6 placed on the conveyor platform 3 to prevent the carrier box 6 placed later from interfering with the carrier box 6 under test.

[0066] Reference Figure 1 The second positioning component 4 is located below the pressurizing component 2. After the first positioning component 4 is released from its lock, the bearing box 6 continues to move along the direction of movement of the transmission component 7, so that the second positioning component 4 locks the bearing box 6, thereby facilitating the pressurizing component 2 to perform pressure testing on the concrete test block inside the bearing box 6.

[0067] Reference Figure 1 The third positioning component 4 is located at the end of the transmission component 7. The third positioning component 4 is used to position the carrier box 6 after the test is completed, so as to reduce the impact of the carrier box 6 slipping off the conveyor platform 3 or sliding randomly on the test of the pressurizing component 2.

[0068] Reference Figure 3 and Figure 4 The positioning component 4 includes a spring 41 and a locking block 42. The conveying platform 3 has a limit hole 32 vertically. An electromagnet 5 is fixedly connected to the bottom of the limit hole 32. One end of the spring 41 is fixedly connected to the electromagnet 5, and the other end is fixedly connected to the locking block 42. A guide slope is provided on the top of the locking block 42. The guide slope is set in the direction of movement of the carrier box 6. The setting of the guide slope facilitates the movement of the locking block 42 into the limit hole 32 when the carrier box 6 abuts against the locking block 42.

[0069] When the electromagnet 5 is energized, it generates a magnetic force on the locking block 42, thereby completely drawing the locking block 42 into the limiting hole 32, thus releasing the locking block 42 from locking the carrier box 6. When the electromagnet 5 is de-energized, the locking block 42 is pushed by the spring 41 and partially passes through the limiting hole 32. The locking block 42 and the carrier box 6 are locked together by their cooperation.

[0070] Reference Figure 5 The support box 6 includes a support box body 61, the upper end of which is open. The side walls of the support box body 61 are transparent, facilitating observation of the state of the concrete sample. Two positioning holes 62 are vertically formed at the bottom of the support box body 61, and each hole 62 cooperates with two positioning components 4 in each group. Positioning blocks are inserted between the positioning holes 62 and the limiting holes 32 to lock the support box 6.

[0071] Reference Figure 4 and Figure 5 The bottom of the bearing box 6 has a vertically opening moving groove 63. There are two moving grooves 63, and the moving grooves 63 and the positioning holes 62 are connected one to one. A moving rod 64 is inserted into the moving groove 63. The two ends of the moving rod 64 pass through the two moving grooves 63 and into the positioning holes 62 respectively. A friction pad 65 is fixedly connected to the middle of the moving rod 64. Limiting blocks are fixedly connected to both ends of the friction pad 65. The limiting blocks pass into the bearing box 61 and restrict the friction pad 65 from rotating freely.

[0072] The friction pad 65 increases the friction between the carrier box 6 and the transmission component 7, making it easier for the transmission component 7 to move the carrier box 6. The moving rod 64 causes the positioning block to push the moving rod 64 upward when the positioning block is inserted into the positioning hole 62, thereby driving the friction pad 65 upward, so that the friction pad 65 is disengaged from the transmission component 7, thus making the carrier box 6 stably locked in the designated position.

[0073] Reference Figure 5 The bottom of the bearing box 61 is provided with a guide groove 66. The length direction of the guide groove 66 is parallel to the length direction of the conveying platform 3. The guide groove 66 is inclined along the length direction. The bottom of the guide groove 66 is connected to the opening of the positioning hole 62. The higher end of the guide groove 66 penetrates the bearing box 61. The width of the higher end of the guide groove 66 is greater than the width of the bottom end of the guide groove 66.

[0074] During the movement of the supporting housing 61, the locking block 42 is initially positioned within the guide groove 66, with its guide slope abutting against the inner wall of the guide groove 66. This allows the locking block 42 to slide stably within the guide groove 66. When the locking block 42 slides out of the guide groove 66, it is engaged in the positioning hole 62 by the action of the spring 41, thus locking the supporting housing 61. The guide groove 66 facilitates the stable engagement of the locking block 42 with the locking hole.

[0075] Reference Figure 1 and Figure 5 The bottom of the support box 61 is equipped with four guide wheels 67, with each pair of guide wheels 67 forming a group, and each group of guide wheels 67 located in the same guide groove 31. The guide wheels 67 facilitate the movement of the support box 61, and the cooperation between the guide wheels 67 and the guide groove 31 guides the movement of the support box 61.

[0076] Reference Figure 1 and Figure 4 In order to facilitate the cooperation between the carrier box 6 and the positioning component 4, an unlocking component 8 is also provided. The unlocking component 8 controls the on and off of the electromagnet 5 in the positioning component 4, thereby controlling the positioning block and facilitating the release of the positioning block from the carrier box 61.

[0077] Reference Figure 1 and Figure 6 The unlocking component 8 includes an unlocking seat 81 and an unlocking handle 82. The unlocking seat 81 is fixedly connected to the side wall of the machine body 1 near the conveying platform 3. An unlocking shaft 83 is threaded through the unlocking seat 81, and the axis of the unlocking shaft 83 is parallel to the length direction of the conveying platform 3. The unlocking handle 82 is rotatably connected to the unlocking shaft 83. A reset torsion spring 84 is sleeved on the unlocking shaft 83. One end of the reset torsion spring 84 is fixedly connected to the unlocking seat 81, and the other end is fixedly connected to the unlocking handle 82.

[0078] By rotating the unlocking handle 82 upwards, all electromagnets 5 are energized. The energized electromagnets 5 then draw the positioning block into the limiting hole 32, thereby releasing the locking of the positioning component 4 onto the carrier box 6.

[0079] Reference Figure 1 and Figure 7 The pressurizing component 2 includes a pressurizing head 21, which is square in shape. When the pressurizing head 21 moves away from the conveying platform 3, it will come into contact with the unlocking handle 82, thereby causing the unlocking handle 82 to rotate upward. When the pressurizing head 21 continues to move upward until it disengages from the unlocking handle 82, the unlocking handle 82 is reset by the action of the reset torsion spring 84.

[0080] The implementation principle of the concrete testing and inspection equipment in this application embodiment is as follows: A concrete test block is placed inside a bearing housing 61, and then the bearing housing 61 is moved to a conveying platform 3, with guide wheels 67 placed in guide grooves 31. When the bearing housing 61 passes the second set of positioning components 4, the second set of locking components positions the bearing housing 61 directly below the pressurizing component 2, allowing the pressurizing probe of the pressurizing component 2 to perform pressure testing on the concrete test block located inside the bearing housing 61.

[0081] After the test is completed, the pressure head 21 moves upward and comes into contact with the unlocking handle 82, thereby releasing the second set of positioning components 4 from locking the carrier box 61, allowing the second carrier box 61 to continue moving along the direction of the conveyor belt, thereby removing the second housing for cleaning.

[0082] By guiding the guide wheel 67 and the guide groove 31, the bearing box 61 can move in a specified direction, and the positioning block and positioning hole 62 are used to achieve stable positioning of the bearing box 61. At the same time, the movement and rotation of the pressure head 21 unlocks the handle 82, thereby transferring the tested concrete sample through the bearing box 61 for testing the next concrete sample.

[0083] This application also discloses a method for using a concrete testing and inspection device:

[0084] Reference Figure 7 S1, Filling the test block. Specifically:

[0085] The concrete test block is placed inside the bearing box 61 from the top.

[0086] Reference Figure 7 S2, Install the carrier box 6. Specifically:

[0087] The support box 61 containing the concrete test block is placed on the conveying platform 3, with all four guide wheels 67 positioned within the guide groove 31. At this time, the transmission assembly 7 on the conveying platform 3 drives the support box 61 to move along the guide groove 31. When the positioning block on the first set of positioning components 4 is inserted into the positioning hole 62 on the support box 61, the first set of positioning components 4 locks the support box 61.

[0088] Reference Figure 7 S3, control unlock. Specifically:

[0089] Rotate the handle 82 upwards to unlock it, then release it from the handle. When the handle is rotated upwards, the electromagnet 5 is energized, which completely attracts the positioning block into the limiting hole 32, thereby releasing the lock on the carrier box 61.

[0090] At this point, the carrier box 61 located in the first positioning component 4 continues to move on the conveyor platform 3 until it is locked by the second positioning component 4. Simultaneously, the carrier box 6 located in the second positioning component 4 continues to move until it is locked by the third positioning component 4.

[0091] Reference Figure 7 S4, control pressurization. Specifically:

[0092] The pressure head 21 in the pressure assembly 2 is moved downwards, so that the pressure head 21 applies pressure to the concrete test block located directly below in the bearing box 6, and the test is performed. During the process of S, steps S1, S2, and S3 can be performed.

[0093] Reference Figure 7 S5, control retraction. Specifically:

[0094] After the test is completed, the pressure head 21 retracts upward. During the upward retraction process, the pressure head 21 will come into contact with the unlocking handle 82, thereby driving the unlocking handle 82 to rotate upward for step S.

[0095] Reference Figure 7 S6. Read parameters. Specifically, read the parameters displayed on unit 1.

[0096] Reference Figure 7 S7. Clean the carrier box 6. Specifically, remove the carrier box 61 located on the third positioning component 4, and clean the concrete test block that has been tested to facilitate S.

[0097] The method of using the concrete testing and inspection equipment in this application embodiment is as follows:

[0098] Fill test block → Install carrier box 6 → Control unlock → Control pressurization → Control retraction → Read parameters → Clean carrier box 6 → Fill test block.

[0099] Concrete test blocks are filled into the support box 61, and the support box 61 is placed on the conveying platform 3. The support box 61 is first locked by the first set of positioning components 4 on the conveying platform 3. By pushing the unlocking handle 82 upward, the support box 61 located in the first set of positioning components 4 is moved to the second set of positioning components 4 for positioning. At this time, the next support box 61 filled with concrete test blocks can be placed on the conveying platform 3.

[0100] Then, the pressure component 2 is operated to perform pressure testing on the concrete test block located on the second group of positioning components 4. After the test is completed, during the upward movement of the pressure component 2, the pressure head 21 abuts against the rotating handle, thereby causing the rotating handle to rotate upward, thereby unlocking the bearing box 61 located on the first group of positioning components 4, and then moving to the second group of positioning components 4 for locking; the bearing box 61 located on the second group of positioning components 4 is unlocked, and then moves to the third group of positioning components 4 for locking.

[0101] After testing, the parameters of the tested concrete block are read, allowing testing of the next concrete block to proceed. During testing, the support box 61 located in the third positioning assembly 4 can be removed for cleaning, facilitating the loading of the next concrete block before it is placed back on the conveyor platform 3. By cleaning and reinstalling the support box 61 during concrete block testing, the pressure probe, after rising, always contains a new concrete block to be tested within the support box 61 located in the second positioning assembly 4, thus achieving continuous testing of concrete blocks and improving testing efficiency.

[0102] 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.
