Description

Technical Field

[0001] This invention relates to the field of engineering testing technology, and in particular to an intelligent testing device for building materials. Background Technology

[0002] In current construction projects, a building material called rubber waterstop is often used. It is usually installed between construction joints to ensure the waterproof performance of the construction joints. Before using rubber waterstop, its various properties are usually tested.

[0003] In existing technologies, cameras or laser sensors are typically used to detect surface cracks in rubber waterstops. During the detection process, the rubber waterstop is usually straight. However, in actual use, the rubber waterstop will undergo deformations such as bending, folding, and stretching. These deformations increase the risk of cracks in the rubber waterstop. Therefore, the crack detection conditions of conventional detection devices are different from the actual use conditions, which reduces the accuracy of the detection results. This can easily lead to the use of defective rubber waterstops during construction, resulting in a decline in construction quality.

[0004] In summary, this application proposes an intelligent detection device for building materials, which improves the aforementioned technical problems. Summary of the Invention

[0006] The technical solution is as follows: An intelligent detection device for building materials includes a base frame; a drive assembly mounted on the base frame; four rectangular connecting frames connected to the drive assembly; the drive assembly drives the connecting frames to move left and right, forward and backward, and up and down; two connecting frames on the left side are rotatably connected to a first limiting plate for bending and deforming a rubber waterstop; two connecting frames on the right side are rotatably connected to a second limiting plate for bending and deforming a rubber waterstop; both the first and second limiting plates are made of elastic material; the first limiting plate is arched upwards, and the second limiting plate is arched downwards; each connecting frame is connected to a pressure plate; the two pressure plates on the left side are located above the first limiting plate; the two pressure plates on the right side are located below the second limiting plate; three detectors are fixedly mounted on the base frame; each detector consists of several cameras and laser sensors; two conveying rollers are rotatably connected to the base frame via mounting brackets; a motor is mounted on the base frame to drive the conveying rollers to rotate.

[0011] As a further preferred option, the surface of the support block is set to be curved.

[0012] As a further preferred option, the support block is made of elastic rubber material.

[0013] As a further preferred option, the first and second limiting plates are detachably connected to the connecting frame.

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] Example 1: Refer to Figures 1-6 As shown, an intelligent detection device for building materials includes a base frame 1; It also includes a drive assembly, connecting frame 2, first limiting plate 3, pressure plate 4, second limiting plate 5, detector 6, and conveyor roller 7; the drive assembly is installed on the base frame 1; four connecting frames 2 arranged in a rectangle are connected to the drive assembly; the drive assembly drives the connecting frames 2 to move left and right, back and forth, and up and down; the two connecting frames 2 on the left side are rotatably connected to the first limiting plate 3 on their lower sides; the two connecting frames 2 on the right side are rotatably connected to the second limiting plate 5 on their upper sides; the first limiting plate 3 is set to arch upwards, and the second limiting plate 5 is set to arch downwards; each connecting frame 2 is connected to a pressure plate 4 by an electric push rod, the electric push rod is hinged to the pressure plate 4, and the electric push rod drives the pressure plate 4 to move up and down; the two pressure plates 4 on the left side are located above the first limiting plate 3; the two pressure plates 4 on the right side are located below the second limiting plate 5; three detectors 6 are fixed to the base frame 1 by a mounting frame; each detector 6 consists of several cameras and laser sensors; two conveyor rollers 7 are rotatably connected to the right side of the base frame 1 by a mounting frame; a motor is installed on the base frame 1 to drive the conveyor rollers 7 to rotate.

[0021] Both the first limiting plate 3 and the second limiting plate 5 are made of elastic material and can switch between curved and flat shapes to facilitate the placement and tightening of the rubber waterstop 8.

[0022] The drive assembly includes a first slide rail 201, a first electric slider 202, a second slide rail 203, a second electric slider 204, and a drive component 205. Two front-to-back symmetrical first slide rails 201 are fixedly mounted on the base frame 1. Two left-to-right symmetrical first electric sliders 202 are slidably connected to each first slide rail 201. The two first electric sliders 202 on the left are fixedly connected to a second slide rail 203 via a mounting plate. The two first electric sliders 202 on the right are also fixedly connected to a second slide rail 203 via a mounting plate. Two front-to-back symmetrical second electric sliders 204 are slidably connected to each second slide rail 203. A drive component 205, which is an electric push rod, is fixedly mounted on each second electric slider 204. The telescopic end of each drive component 205 is fixedly connected to the adjacent connecting frame 2.

[0023] The surfaces of the first limiting plate 3, the pressure plate 4, and the second limiting plate 5 are all made smooth to reduce the friction between them and the rubber waterstop 8.

[0024] The conveyor roller 7 is made of flexible rubber material so that the arc-shaped ribs 8001 and square ribs 8002 on the rubber waterstop 8 can pass through the conveyor roller 7.

[0025] Furthermore, to prevent the rubber waterstop 8 from slipping between the conveyor rollers 7, anti-slip grooves are provided on the surface of the conveyor rollers 7.

[0026] It also includes support blocks 301; several support blocks 301 are fixedly connected to the upper surface of the first limiting plate 3; several support blocks 301 are also fixedly connected to the lower surface of the second limiting plate 5.

[0027] The surface of the support block 301 is set to be curved to ensure that the groove 8003 part of the rubber waterstop 8 can be bent.

[0028] Furthermore, to improve the support and adaptation of the rubber waterstop 8, the support block 301 is made of elastic rubber material.

[0029] Furthermore, to improve the adaptability to different types of rubber waterstops 8, the first limiting plate 3 and the second limiting plate 5 are detachably connected to the connecting frame 2.

[0030] The upper and lower surfaces of the rubber waterstop 8 are provided with arc-shaped ribs 8001, and the upper and lower surfaces are provided with several square ribs 8002. The following describes in detail the testing process of the rubber waterstop 8 with the above shape. Initially, both the first limiting plate 3 and the second limiting plate 5 are in a straight position. The operator first inserts one end of the rubber waterstop 8 between the first limiting plate 3 and the adjacent pressure plate 4, and pulls the rubber waterstop 8 to the right, allowing it to pass sequentially between the second limiting plate 5 and the adjacent pressure plate 4, and between the two conveying rollers 7. The electric push rod in the connecting frame 2 is then controlled to move the corresponding pressure plate 4 to fit against the front and rear edges of the rubber waterstop 8, ensuring that the rubber waterstop 8 adheres to the surfaces of the first limiting plate 3 and the second limiting plate 5. Then, the second electric slider 204 is controlled to move the corresponding connecting frame 2 towards each other on the second slide rail 203, causing the first limiting plate 3 to bend upwards and the second limiting plate 5 to bend downwards, thus causing different parts of the rubber waterstop 8 to bend upwards and downwards respectively, as shown in the image. Figure 2 As shown, the motor mounted on the base frame 1 then drives the conveyor roller 7 to rotate. Using a front-to-back view as a reference, the upper conveyor roller 7 rotates counter-clockwise, and the lower conveyor roller 7 rotates clockwise. This rotation of the conveyor roller 7 causes the rubber waterstop 8 to continuously move to the right, allowing it to slide continuously between the first limiting plate 3 and the pressure plate 4, and between the second limiting plate 5 and the pressure plate 4. Note that the smooth surfaces of the first limiting plate 3, the pressure plate 4, and the second limiting plate 5 effectively reduce the coefficient of friction with the rubber waterstop 8. This allows the rubber waterstop 8 to sequentially pass through a straight state, upward bending deformation, and downward bending deformation, ultimately returning to its original state. After returning to a straight state, and after passing through the first limiting plate 3 and the second limiting plate 5, the surface flatness of the rubber waterstop 8 is detected by the camera and laser sensor on the detector 6 to ensure that the appearance of the rubber waterstop 8 meets the requirements. Compared with the conventional detection method, the rubber waterstop 8 is subjected to a large bending deformation by the first limiting plate 3 and the second limiting plate 5. If the rubber waterstop 8 develops cracks due to bending or has original cracks, bending the rubber waterstop 8 can widen the crack width so that the detector 6 can quickly detect the crack defects on the rubber waterstop 8, thereby ensuring the quality of use of the rubber waterstop 8.

[0031] Based on this, and considering that the rubber waterstop 8 may be subjected to overlapping, stretching, and torsion under external forces during use, the conveyor roller 7 can be paused during the bending process of the rubber waterstop 8, keeping the rubber waterstop 8 stationary. Then, the electric push rod in the connecting frame 2 drives the corresponding pressure plate 4 to compress the rubber waterstop 8. This, in conjunction with the pressure plate 4, the first limiting plate 3 and the second limiting plate 5 clamp the rubber waterstop 8. Finally, the first electric slider 202 is controlled to move the corresponding first limiting plate 3 and the second limiting plate 5 towards each other on the first slide rail 201, thus... The rubber waterstop 8 overlaps between the first limiting plate 3 and the second limiting plate 5. Since the rubber waterstop 8 between the first limiting plate 3 and the second limiting plate 5 is in a transitional section between upward and downward bending deformation, its own deformation is large. Combined with the deformation caused by the overlap of the transition section, this simulates the overlapping bending condition that the rubber waterstop 8 may encounter during transportation. Then, the detector 6 detects whether the rubber waterstop 8 will develop cracks or damage under various overlapping bending conditions. After the detection is completed, the first electric slider 202 is controlled to drive the first limiting plate 3 and the second limiting plate 5 to move in opposite directions. The transition section of the rubber waterstop 8 is subjected to tensile stress. This is used in conjunction with the detector 6 to test the tensile strength of the rubber waterstop 8 under significant bending deformation. Furthermore, after the above tests are completed, the extension end of the front drive member 205 corresponding to the first limiting plate 3 is extended, and the extension end of the rear drive member 205 is shortened, making the front of the first limiting plate 3 higher than the rear. Using a left-to-right view as a reference, this allows the first limiting plate 3 to deflect counterclockwise. Similarly, controlling the extension and retraction of the two drive members 205 corresponding to the second limiting plate 5 allows the second limiting plate 5 to deflect clockwise, thereby reducing the stress on the transition section of the rubber waterstop 8. The section twists, which is used in conjunction with the detector 6 to detect the torsional resistance of the rubber waterstop 8 in the bending state. After the torsional resistance of the rubber waterstop 8 is tested, the conveyor roller 7 can be controlled to continue rotating, so that the rubber waterstop 8 continues to be conveyed to the right, thereby detecting defects on the surface of the entire rubber waterstop 8. It should be noted that the conveyor roller 7 is made of flexible rubber material so that the arc-shaped ribs 8001 and square ribs 8002 on the rubber waterstop 8 can pass through the conveyor roller 7. At the same time, the anti-slip grooves on the surface of the conveyor roller 7 increase the friction between the conveyor roller 7 and the rubber waterstop 8, preventing the rubber waterstop 8 from slipping between the conveyor rollers 7.

[0032] In summary, when the rubber waterstop 8 is in a bent state, the first limiting plate 3 and the second limiting plate 5 work together to overlap, stretch, and twist it, so that the testing conditions of the rubber waterstop 8 are more in line with the actual use situation, thus improving the accuracy of the test results.

[0033] Based on this, since the rubber waterstop 8 has an arc-shaped rib 8001 in the middle and square ribs 8002 on the front and rear sides, when the rubber waterstop 8 is arched by the first limiting plate 3 or the second limiting plate 5, the groove 8003 formed between the arc-shaped rib 8001 and the square rib 8002, as well as the groove 8003 between two adjacent square ribs 8002, cannot fit with the surface of the limiting plate. Therefore, the groove 8003 of the rubber waterstop 8 is not bent. To address this, when the rubber waterstop 8 is placed on the first limiting plate 3 or the second limiting plate 5, the support block 301 on its surface contacts the adjacent groove 8003. The support block 301 applies directional pressure to the groove 8003 to ensure that the groove 8003 bends. This allows the edges of the arc-shaped rib 8001 or the square rib 8002 to be further bent. The bending deformation improves the bending detection effect of the rubber waterstop 8. Note that the surface of the support block 301 is curved to ensure that the groove 8003 can bend after contacting the support block 301. At the same time, the support block 301 is made of elastic rubber material to accommodate the different width gaps between the groove 8003 on the rubber waterstop 8 and the surface of the limiting plate. In addition, considering that the number and spacing of the square ribs 8002 of the rubber waterstop 8 are different for different types, the first limiting plate 3 and the second limiting plate 5 are detachably connected to the connecting frame 2. Different numbers and spacings of the first limiting plate 3 and the second limiting plate 5 are adapted for different types of rubber waterstop 8. In this way, the first limiting plate 3 and the second limiting plate 5 can be replaced according to the type of rubber waterstop 8, improving the adaptability to the detection of different types of rubber waterstop 8.

[0034] Example 2: Based on Example 1, referring to... Figure 5 and Figure 6 As shown, it also includes a water spray pipe 302; a cavity 3001 is opened in both the first limiting plate 3 and the second limiting plate 5; each cavity 3001 is connected to an external water supply device through a pipe; a water spray pipe 302 is installed through the middle of each support block 301; all water spray pipes 302 are connected to the adjacent cavity 3001; the nozzle of the water spray pipe 302 faces to the left.

[0035] Furthermore, to reduce water flow resistance and facilitate smooth water flow from the spray pipe 302 to the groove 8003, each support block 301 has a slope 30101 on its left side; the outlet of each spray pipe 302 is located on the adjacent slope 30101.

[0036] Considering that the groove 8003 of the rubber waterstop 8 is prone to trapping dust, sand, and other impurities, and is difficult to clean thoroughly, during the inspection of the rubber waterstop 8, the external water supply device is controlled to supply water to the cavity 3001 through the pipe, so that the water flow is sprayed through the water spray pipe 302 onto the groove 8003 of the rubber waterstop 8. This achieves the cleaning of dust, sand, and other impurities trapped in the groove 8003. The water flow in the water spray pipe 302 is sprayed from right to left, which is opposite to the direction of the rubber waterstop 8 being transported from left to right. This prevents the impurities washed out from re-adhere to the surface of the rubber waterstop 8. At the same time, by setting the outlet of the water spray pipe 302 on the inclined surface 30101, a gap is created between the water spray pipe 302 and the rubber waterstop 8, reducing the resistance to the water flow, so that the water flow can be smoothly sprayed from the water spray pipe 302 onto the groove 8003.
