Description

TECHNICAL FIELD

[0001] The application relates to the technical field of detection devices, in particular to a plate toughness detection device for building construction. BACKGROUND

[0002] With the development of building construction technology, plate toughness detection technology has emerged. By applying external force to the plate, the deformation of the plate under stress is detected, and the anti-deformation ability of the plate can be identified within a short time, so as to judge the toughness of the plate.

[0003] In the related art, for example, a square plate toughness detection device for building construction disclosed in patent CN114354343A clamps the plate in the limiting mechanism, and uses the supporting mechanism to support the plate. The lower pressing block is used to extrude the plate, and the toughness is judged by observing the deformation degree of the plate with the naked eye. If the plate is not crushed, the toughness detection is passed.

[0004] However, in the toughness detection process, the plate that does not meet the toughness requirement may have slight deformation or micro-cracks. However, due to the subjectivity and instability of manual operation, such changes may not be accurately perceived by the naked eye, which may lead to misjudgment of the poor quality plate as qualified during the detection process, thereby affecting the quality stability of the plate. The limiting mechanism is limited to the size of the device design, and cannot meet the detection requirements of plates of different sizes and special shapes. Special plates cannot be fixed on the platform, which has great limitations in actual application. In addition, the single pressing block applies pressure to the plate, which may cause uneven pressure and abnormal local deformation of the plate, thereby affecting the judgment of the overall toughness of the plate.

[0021] Compared with the prior art, the plate toughness detection device for building construction has the beneficial effects that:

[0022] 1. The base plate is the basic structure of the entire device, on which a slide rail mechanism is installed. The slide rail mechanism includes at least two slide tables, which are located on opposite sides of the base plate. The slide tables are provided with slide grooves, and each slide table has a corresponding clamping component. The clamping component has a slide base, and a slide column is provided at the bottom of the slide base. The slide column is embedded in the slide groove to ensure smooth and stable movement of the slide base. The slide column can drive the slide base to reciprocate along the length of the slide groove. The slide rail mechanism provides a moving path for the clamping components through the combination of slide tables and slide grooves, so that the two opposite clamping components can move and adjust their positions precisely.

A pressure plate is installed inside the U-shaped plate, which works with the U-shaped plate to clamp the plate. This pressure plate can accommodate plates of different thicknesses and prevents the plate from shifting or sliding during the toughness test, thus improving the accuracy of the toughness test. The U-shaped plate is connected to a clamping mechanism, which is driven by the pressure plate. The clamping mechanism drives the pressure plate away from or towards the bottom surface of the U-shaped plate, controls the position of the pressure plate, and adjusts the clamping force on the plate.

[0039] Referring to Figures 1-3 The structural schematic diagram of the building construction plate toughness detection device of the application is shown. The embodiment of the application provides a building construction plate toughness detection device, which comprises a bottom plate 1. The bottom plate 1 can be square in shape. The bottom plate 1 serves as the basic structure of the whole device. Various mechanisms are arranged on the bottom plate 1, so that the device is more integrated. A sliding rail mechanism 2 is installed on the bottom plate 1. One sliding rail mechanism 2 comprises at least two sliding tables 21. The two sliding tables 21 are respectively located on opposite sides of the bottom plate 1. Sliding grooves 22 are formed in the sliding tables 21. The sliding rail mechanism 2 guides the clamping assembly 3 to move linearly along the sliding grooves 22 by forming the sliding grooves 22 in the sliding tables 21. Specifically, the sliding grooves 22 of the two oppositely arranged sliding tables 21 are in a collinear position.

[0040] Referring to Figure 1 and Figure 6 Each sliding table 21 is correspondingly provided with a clamping assembly 3. The clamping assembly 3 has a sliding seat 31. A sliding column 32 is arranged at the bottom of the sliding seat 31. The sliding column 32 is embedded in the sliding groove 22. The sliding column 32 can drive the sliding seat 31 to move reciprocally along the length direction of the sliding groove 22. The sliding seat 31 and the sliding column 32 cooperate with the sliding table 21 and the sliding groove 22 to realize the adjustable movement of the clamping assembly 3. The two opposite clamping assemblies 3 are accurately moved and adjusted in position to adapt to different sizes of plates. Whether it is a large size or a special-shaped plate, it can be clamped through the position adjustment of the clamping assembly 3, thereby improving the application range and detection flexibility of the building construction plate toughness detection device.

[0041] Referring toFigure 6 The fixing frame 33 is arranged on the sliding base 31, and the U-shaped plate 34 is fixed at a distance from the ground, so that the U-shaped plate 34 keeps a certain distance from the ground when clamping the plate, and the plate can freely deform when receiving the pressure of the pressing mechanism 5, avoiding the improper support of the ground inequality to the plate, and enabling the plate to withstand the maximum pressing pressure, and clearly obtaining the toughness of the plate. The U-shaped plate 34 is fixed on the fixing frame 33, and the U-shaped plate 34 has an upper piece and a lower piece. The U-shaped plate 34 is provided with a pressing plate 35, and the side wall of the U-shaped plate 34 is provided with an elongated hole. One side of the pressing plate 35 is clamped in the elongated hole, so that the pressing plate 35 cannot be displaced. The U-shaped plate 34 is connected with a pressing mechanism 36, and the pressing mechanism 36 is in driving connection with the pressing plate 35. The pressing mechanism 36 drives the pressing plate 35 to move away from or close to the inner bottom surface of the U-shaped plate 34. When the pressing plate 35 is close to the inner bottom surface of the U-shaped plate 34, the plate is clamped. The design of the pressing plate 35 can clamp plates of different thicknesses, prevent the position of the plate from shifting or sliding during the pressing process, and improve the accuracy of toughness detection. The pressing mechanism 36 accurately controls the clamping force of the pressing plate 35, which can avoid damage to the plate due to excessive clamping force, or the problem of sliding caused by insufficient clamping force, and improves the reliability of fixing the plate.

[0042] Referring to Figure 1 The openings of the U-shaped plates 34 of the two opposite clamping assemblies 3 are oppositely arranged and jointly face the plate. The plate can be clamped by the method of approaching the plate by the two opposite clamping assemblies 3, which improves the automation degree and clamping efficiency of the clamping assembly 3, and clamping and fixing the opposite ends of the plate helps to improve the stability of the plate during detection.

[0043] Referring to Figure 1The bottom plate 1 is provided with a support frame 4 fixed at the middle of the opposite sides of the bottom plate 1, used for installing a rotating rod 41, which can be a cuboid, and the two ends of the rotating rod 41 are rotatably connected to the support frame 4. By rotating the rotating rod 41, the rotating rod 41 can be adjusted so that different faces of the rotating rod 41 face the plate. The first face of the rotating rod 41 is fixed with a pressing mechanism 5, which is used to apply pressure to the plate. When detecting the plate, first, the first face of the rotating rod 41 faces the plate, and the pressing mechanism 5 applies uniform pressure to the plate. According to the actual stress condition of the model plate, the toughness and deformation capacity of the plate under external force are tested. The second face of the rotating rod 41 opposite to the first face is provided with a developing mechanism. After the plate receives the pressure, the rotating rod 41 is turned to the second face facing the plate, and the developing mechanism is used to enhance the deformation display or crack display of the plate, and to enlarge the subtle changes of the plate. The problem of subtle cracks or deformation that is difficult to detect with the naked eye is solved, so that the detection personnel can more directly and intuitively observe the changes of the plate after the force is applied, reducing the error of manual observation and improving the reliability of the detection structure. It is ensured that unqualified plates are accurately identified to avoid quality problems in engineering.

[0044] Referring to Figure 3 and Figure 5 , the developing mechanism is a projector 6 fixed in the middle of the rotating rod 41, which is used to project colored stripes on the plate. The projector 6 projects horizontal and vertical colored stripes on the plate. When the plate is in a non-deformation state after being subjected to pressure, the colored stripes on the plate remain in their original state. If the plate deforms after being subjected to pressure, the projected stripes on the surface of the plate will correspondingly appear distorted, curved, and have changes in spacing. By observing and analyzing the deviation of the colored stripes from the original state with the naked eye, it can be determined whether the plate has deformed and the degree of deformation. The detection personnel can quickly determine whether the plate meets the toughness requirements, solving the problem of traditional naked-eye direct observation of the plate that is difficult to capture the changes of the plate.

[0045] Referring to Figure 1 and Figure 4The developing mechanism is the coating mechanism 7, the rotating rod 41 is provided with a guide rail 42 along the length direction, the coating mechanism 7 comprises a base 71, a plurality of telescopic rods 72, a coating roller 73 and a UV lamp, the base 71 is arranged on the guide rail 42, the base 71 drives the coating mechanism 7 to move along the guide rail 42, the guide rail 42 provides the base 71 with a path that can move in a certain direction of the plate, facilitating uniform coating of the plate of different sizes and shapes, the telescopic rods 72 are respectively spherically hinged on the base 71, the spherical hinge mode can adapt to different angles formed by the telescopic rods 72 and the plate when the coating roller 73 is at different positions of the plate, the telescopic rods 72 can be telescopic, so that the coating roller 73 covers the range of the plate in the vertical direction of the rotating rod 41, the two ends of the coating roller 73 are respectively connected to the telescopic rods 72, the coating roller 73 rolls around the central axis, and the fluorescent dye is uniformly coated on the surface of the plate through rolling, the telescopic rods 72 change the length and angle to make the coating roller 73 fully coated with the fluorescent dye on the plate, when the plate is coated with the fluorescent dye, the coating roller 73 is first moved to one end of the rotating rod 41, and then the fluorescent dye is coated from the middle to one side of the plate, and then the fluorescent dye is coated from the middle to the other side of the plate, after the fluorescent dye is coated, the coating roller 73 moves a certain distance along the rotating rod 41, and then the above operation is repeated. The coating roller 73 is used to uniformly coat the fluorescent dye on the plate, and since the cracks on the plate and the plate surface are not in the same plane, they cannot be covered by the fluorescent dye, and under the irradiation of the UV lamp, the plate develops the fluorescent dye, and the cracks are displayed in the fluorescent dye, so that the detection personnel can identify them, and the detection accuracy is improved.

[0046] Wherein, referring to Figures 1-3 The slide rail mechanism 2 is provided with two groups, and the four slide tables 21 corresponding to the two groups of slide rail mechanisms 2 are distributed in a quadrilateral shape. The four slide tables 21 correspond to the clamping assemblies 3, which provide four-point support for the plate, so that the plate remains stable during detection.

[0047] The support device 8 is arranged on the bottom plate 1, and the support device 8 comprises a driving mechanism 81 and a support plate 82. The driving mechanism 81 can drive the support plate 82 to move away from or close to the bottom plate 1. The support plate 82 can be adjusted to a position close to the bottom plate 1, so that the detection personnel can place the plate on the support plate 82. The support plate 82 supports the plate to rise to the same height as the clamping assemblies 3. The two groups of clamping assemblies 3 preliminarily support the plate on the inner bottom surface of the U-shaped plate 34 by approaching the plate, and then further clamp the plate through the pressing plate 35.

[0048] The support plate 82 is provided with a pressure sensor connected with the pressing mechanism 5, which is used to limit the deformation degree of the plate. After the clamping assembly 3 clamps the plate, the support plate 82 is lowered by a certain distance, which is determined by the standard of the ductility deformation of the plate. When the plate is deformed by the pressure of the pressing mechanism 5 and touches the pressure sensor on the support plate 82, it is determined that the plate has passed the standard ductility test. At this time, the pressing mechanism 5 stops applying pressure to avoid unnecessary damage to the plate due to excessive pressure of the pressing mechanism 5, reducing the risk of crushing the qualified plate and reducing the production cost.

[0049] Referring to Figure 6 The pressing mechanism 36 includes a support rod 361 and a compression spring 362. The support rod 361 is movably inserted into the U-shaped plate 34, and the bottom of the support rod 361 is fixedly connected with the pressing plate 35. The compression spring 362 is sleeved on the support rod 361, and the two ends of the compression spring 362 abut against the top surface of the U-shaped plate 34 and the pressing plate 35, respectively. The compression spring 362 ensures that the pressing plate 35 has a certain deformation space when fixing the plate, so that the plate can avoid direct damage due to lack of deformation space when receiving the ductility test of the pressing mechanism 5, thereby reducing the production cost.

[0050] Referring to Figure 4 and Figure 5 The pressing mechanism 5 includes a plurality of pressing blocks 51 and hydraulic cylinders 52 corresponding to the pressing blocks 51. By controlling the hydraulic cylinders 52 to drive the pressing blocks 51 to press the plate, compared with the single-point pressing mechanism 5, the plurality of pressing blocks 51 can uniformly press the plate to avoid abnormal deformation caused by local pressure concentration, so as to more accurately reflect the overall ductility performance of the plate. The pressing mechanism 5 can accurately control the pressure, reduce the excessive damage to the plate, and make the ductility test more scientific.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0052] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
