Description

Technical Field

[0001] This invention relates to building material testing technology, specifically to a compressive strength testing device for energy-saving building materials. Background Technology

[0002] Energy-efficient building materials refer to those materials that can effectively reduce energy consumption, improve building energy efficiency, and reduce environmental burden during building design, construction, and use. They reduce building energy demand and promote sustainable building development by providing excellent thermal insulation, sound insulation, and other properties.

[0003] Autoclaved aerated concrete (AAC) blocks are a commonly used energy-saving building material in construction, possessing advantages such as lightweight, environmental friendliness, and excellent thermal insulation and fire resistance. To ensure that the load-bearing capacity of AAC blocks meets actual construction needs, their compressive strength is typically tested during the production process. Existing AAC block strength testing equipment has relatively limited functionality, only capable of testing the strength of AAC blocks. Furthermore, the preparatory work required before testing must be done manually, making the testing process quite laborious.

[0004] Chinese invention patent CN120121412B discloses a strength testing device for aerated concrete blocks. Before testing, the device grinds the sides of the aerated concrete blocks to automatically standardize their dimensions. However, in actual testing, the requirements for aerated concrete blocks go far beyond this. The upper and lower surfaces of the blocks also need to be inspected to ensure they are flat and free of obvious cracks. Furthermore, the stress area of ​​the blocks needs to be accurately measured before testing. All these preparatory steps require manual operation, which can easily lead to significant errors in testing accuracy and hinder the strength testing of aerated concrete blocks.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: Please see Figures 1-6 A compressive strength testing device for energy-saving building materials includes a testing body 1 and a support platform 101 set on the testing body 1. The testing body 1 is equipped with a pressure testing unit 102 located above the support platform 101. The testing body 1 is equipped with a controller 103. A pretreatment box 2 and a conveyor belt 21 are arranged sequentially on one side of the support platform 101. An air-filled block to be tested is placed on the conveyor belt 21.

[0023] It should be noted that the pressure testing unit 102 is an existing mechanism, which includes a pressure part and a pressure block. The pressure part applies a downward force to the pressure block, so that the pressure block can apply pressure to the gas block to be tested placed on the support platform 101, and the pressure value is monitored and recorded in real time. Finally, the pressure value when the gas block to be tested is destroyed is obtained, and the pressure test of the gas block to be tested is completed. This technology is existing technology and will not be described in detail here.

[0024] Image acquisition cameras 22 are installed at both the upper and lower ends of the inner wall of the pretreatment box 2, near the side of the conveyor belt 21. Grinding robotic arms 23 are installed at both the upper and lower ends of the inner wall of the pretreatment box 2, located near the side of the image acquisition cameras 22, near the support platform 101. Grinding discs 24 are provided at the ends of the grinding robotic arms 23. A transfer platform 25 connected to the support platform 101 is installed at the bottom of the inner wall of the pretreatment box 2. A pushing unit corresponding to the transfer platform 25 is installed at the bottom of the inner wall of the pretreatment box 2. A measuring unit located between the transfer platform 25 and the grinding robotic arm 23 is installed at the top of the inner wall of the pretreatment box 2. A conveying unit for conveying the aerated concrete blocks to be tested is installed inside the pretreatment box 2.

[0025] It should be noted that the conveyor belt 21 is driven by a motor and rollers. The motor driving the conveyor belt 21, the image acquisition camera 22, the grinding robot arm 23, the pushing unit, the measuring unit, and the conveying unit are all electrically connected to the controller 103. During operation, the gas block to be tested is conveyed to the interior of the pretreatment box 2 by the conveyor belt 21, and then conveyed to the position of the grinding robot arm 23 by the conveying unit. During this process, it passes through the image acquisition camera 22, which captures images of its upper and lower surfaces and transmits them to the controller 103. The controller 103 determines whether surface grinding is required based on the actual state of the surface. When surface grinding is not required, the conveying unit conveys it to the surface of the transfer table 25 and pushes it to the test position on the bearing platform 101 by the pushing unit. Then, the pressure test unit performs a pressure test on it.

[0026] In addition, an infrared sensor corresponding to the position of the conveyor belt 21 can be installed on the inner wall of the pretreatment box 2, which can be used to accurately locate the position of the gas block to be tested, thereby facilitating the clamping block 57 to accurately clamp it.

[0027] The specific structure of the pushing unit is described below. The pushing unit includes a lifting electric rod 3 vertically installed at the bottom of the inner wall of the pretreatment box 2. A bearing plate 31 is installed on the top of the lifting electric rod 3. Guide columns that penetrate the bottom surface of the inner wall of the pretreatment box 2 and are slidably connected to the inner wall are installed on both sides of the bottom of the bearing plate 31. A feeding electric rod 32 is installed on the surface of the bearing plate 31. A feeding plate 33 is installed at the end of the telescopic end of the feeding electric rod 32. Guide rods that penetrate the bearing plate 31 and are slidably connected to the inner side of the feeding plate 33 are installed on both sides of the surface of the feeding plate 33.

[0028] It should be noted that the upper surface of the transfer table 25 is smooth and can be polished or coated with an anti-slip coating, which greatly reduces the resistance when the gas block to be tested slides on its surface, thus making it less prone to wear.

[0029] In addition, the upper surface of the transfer station 25 is flush with the surface of the support platform 101, and the position of the feeding plate 33 corresponds to that of the transfer station 25. When not in operation, the top position of the feeding plate 33 is lower than the upper surface of the transfer station 25, so that it will not obstruct the conveying of the gas block to be tested. When in operation, the bottom position of the feeding plate 33 is higher than the top position of the transfer station 25, so that it can smoothly push the gas block to be tested to the test position on the support platform 101.

[0030] The specific structure of the measuring unit is described below. The measuring unit includes a mounting plate 4 that is slidably connected to the inner side of the pretreatment box 2. Four upright plates 41 are symmetrically mounted in a rectangular shape at the bottom of the mounting plate 4. A horizontal electric rod 42 is mounted on the inner side of the upright plate 41. A detection plate 43 is mounted on the telescopic end of the horizontal electric rod 42. Guide rods that penetrate the upright plate 41 and are slidably connected to its inner side are symmetrically mounted on both ends of the outer side of the detection plate 43. A distance sensor 44 is provided on the surface of one of the detection plates 43 and the adjacent detection plate 43. A lifting electric rod 45 is mounted on the top of the pretreatment box 2. The telescopic end of the lifting electric rod 45 penetrates the top of the pretreatment box 2 and is fixedly connected to the mounting plate 4.

[0031] It should be noted that the horizontal electric rod 42, the lifting electric rod 45, and the distance sensor 44 are all electrically connected to the controller 103. During operation, when the gas block to be tested is transported to the measurement position, the lifting electric rod 45 drives the mounting plate 4 to move the detection plate 43 downward, so that the position of the detection plate 43 corresponds to the gas block to be tested. Then, the horizontal electric rod 42 drives the detection plate 43 to move until it contacts the surface of the gas block to be tested. After that, the distance sensor 44 measures the side length of the gas block to be tested and transmits the measurement data to the controller 103, so that the controller 103 can accurately calculate the force-bearing area of ​​the gas block to be tested based on the obtained data.

[0032] The specific structure of the conveying unit is described below. The conveying unit includes straight grooves symmetrically opened on both sides of the pretreatment box 2. A drive block 5 is slidably connected to the inner side of the straight groove. Conveying screws 51 are installed on both sides of the pretreatment box 2. The drive block 5 is threadedly connected to the conveying screw 51. A vertical groove is opened on the top of the opposite side of the two drive blocks 5. A lifting screw 52 is installed inside the vertical groove. A lifting block 53 is threadedly connected to the outside of the lifting screw 52. The same mounting frame 54 is fixedly connected between the two lifting blocks 53. A clamping screw 55 is installed inside the mounting frame 54. The central axis of the clamping screw 55 is set perpendicular to the conveying direction of the gas block to be tested. A clamping seat 56 is threadedly connected to the outside of the clamping screw 55. A receiving groove is opened on the opposite side of the two clamping seats 56. A clamping block 57 is slidably connected to the inner side of the receiving groove. The height of the clamping block 57 is half the height of the gas block to be tested. Multiple sets of pressure springs 58 are installed between the clamping block 57 and the inner wall of the receiving groove.

[0033] It should be added that the conveying screw 51, the lifting screw 52, ​​and the clamping screw 55 are all driven by motors, and the motors driving the conveying screw 51, the lifting screw 52, ​​and the clamping screw 55 are all electrically connected to the controller 103.

[0034] Furthermore, one end of the conveyor belt 21 extends into the pretreatment box 2, and the stroke position of the conveyor screw 51 is adapted to the conveyor belt 21, that is, the conveyor screw 51 drives the clamping block 57 to move so as to clamp and convey the gas block to be tested on the conveyor belt 21.

[0035] In addition, the clamping surface of the clamping block 57 is rough, which makes the clamping block 57 more stable when clamping the gas block to be tested. The clamping seat 56 is slidably connected to the inner side of the mounting frame 54, which allows the clamping seat 56 to maintain a stable movement state during the movement.

[0036] During the test, the operator places multiple sets of gas blocks to be tested on the conveyor belt 21 and transports them to a fixed position via the conveyor belt 21. Then, the drive block 5 is moved by the conveyor screw 51, which causes the drive block 5 to move the clamping block 57 to the gas block to be tested. At this time, the clamping block 57 is moved downward to the middle position of the gas block to be tested by the lifting screw 52. Then, the clamping screw 55 drives the clamping seat 56 to move. At this time, the clamping block 57 moves synchronously and contacts the surface of the gas block to be tested. After that, the clamping seat 56 continues to move and compresses the pressure spring 58, which increases the contact pressure between the clamping block 57 and the gas block to be tested, thereby enabling stable clamping of the gas block to be tested. Afterwards, the drive block 5 is moved to the grinding robot arm 23 by the conveying screw 51. During this process, it passes by the image acquisition camera 22 and the image acquisition camera 22 acquires images of its upper and lower surfaces. The controller 103 can determine whether the gas block to be tested meets the test requirements and whether its upper and lower surfaces need to be ground flat based on the acquired data. When grinding is not required, it is directly conveyed to the measurement unit. When grinding is required, the position of the grinding disc 24 is adjusted by the grinding robot arm 23 so that the upper and lower surfaces of the gas block to be tested are fully ground to ensure the flatness of its upper and lower surfaces. After grinding is completed, it is conveyed to the measurement unit. After the gas block to be tested is transported to the measuring unit, the lifting electric rod 45 drives the mounting plate 4 to move the detection plate 43 downward, so that the position of the detection plate 43 corresponds to the gas block to be tested. Then, the horizontal electric rod 42 drives the detection plate 43 to move until it contacts the surface of the gas block to be tested. After that, the distance sensor 44 measures the side length of the gas block to be tested and transmits the measurement data to the controller 103, so that the controller 103 can accurately calculate the force area of ​​the gas block to be tested based on the obtained data. After the measurement is completed, the detection plate 43 is reset, and the conveying screw 51 continues to drive the clamping block 57 to move and transport the gas block to be tested to the transfer platform 25. Then, the lifting electric rod 3 drives the bearing plate 31 to move upward, so that the feeding plate 33 moves to a position higher than the transfer platform 25. Then, the feeding electric rod 32 drives the feeding plate 33 to move and push the gas block to be tested to the test position on the bearing platform 101, so that the pressure testing unit 102 can perform a pressure test on the gas block to be tested.

[0037] Example 2: Please see Figure 1 , Figure 6 This embodiment provides a technical solution based on the above embodiments: a bracket 6 is installed on one side of the support platform 101, a cleaning electric rod 61 is installed on the bracket 6, a cleaning push plate 62 is installed at the end of the telescopic end of the cleaning electric rod 61, a guide column is installed on the surface of the cleaning push plate 62 that penetrates the bracket 6 and is slidably connected to its inner wall, the bottom surface of the cleaning push plate 62 is flush with the upper surface of the support platform 101, and the size and specifications of the cleaning push plate 62 are adapted to the aerated block to be tested, a discharge guide plate 63 is installed on the other side of the support platform 101, and a collection box corresponding to the discharge guide plate 63 is placed on the side of the support platform 101.

[0038] After the test is completed, the cleaning push plate 62 is moved by the cleaning electric rod 61, so that the bottom surface of the cleaning push plate 62 can slide along the surface of the support platform 101, and in the process, it pushes the air block to be tested on its surface to move, so that it can fall from the other side onto the discharge guide plate 63, slide down along the surface of the discharge guide plate 63 and be collected.

[0039] Example 3: Please see Figure 2 , Figure 6 This embodiment provides a technical solution based on the above embodiment: air boxes 7 are installed at both the upper and lower ends of the inner wall of the pretreatment box 2, and air holes 71 are opened on the surface of the two air boxes 7 facing each other. Suction pipes 72 are connected to the outside of the air boxes 7, and the suction pipes 72 are connected to the external suction unit. The position of the air boxes 7 corresponds to the grinding robot arm 23.

[0040] It should be noted that the end of the suction pipe 72 is connected not only to an external suction unit, but also to a dust collection unit, which can effectively collect the dust generated during the polishing process.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
