Description

Technical Field

[0001] The present invention relates to the technical field of insulation board performance detection, and particularly to a device for detecting the mechanical properties of polystyrene insulation boards. Background Art

[0002] Polystyrene insulation board is a commonly used building material, widely used in the thermal insulation of walls, roofs and floors. In order to ensure its performance in actual applications, especially its mechanical bending resistance performance, corresponding tests must be carried out. Among them, the mechanical bending resistance performance detection device is a special equipment used to evaluate the strength and stiffness of this material under stress. This device usually consists of main parts such as a support frame, a loading device, a measurement system and a data processing system. The support frame is used to fix the sample to ensure its stability during the test; the loading device applies a uniform concentrated force to simulate the stress situation in actual use; the measurement system monitors the deformation of the sample in real time, usually including displacement sensors and force sensors, which can accurately record the deflection of the sample and the applied force value; the data processing system analyzes the collected data and generates a relevant report on the bending resistance performance; during the test, when the polystyrene insulation board is subjected to the force applied by the loading device, its middle part will bend to form a deflection. According to the bending theory in material mechanics, the bending strength of the material is closely related to its geometric shape, material properties and the applied force. By recording the applied force and the corresponding deflection, a force-deflection curve can be plotted, thereby calculating key indicators such as the bending resistance strength and stiffness of the material. At present, when applying a load to the polystyrene insulation board, one end of the polystyrene insulation board needs to be fixed, and the loading device applies a force to the other end of the polystyrene insulation board to form a deflection. At this time, since one end of the polystyrene insulation board is fixed, after the loading device applies the force, the deflection is mainly concentrated at the free end of the insulation board. In this case, the change in deflection mainly occurs in the area far from the fixed end, while the area near the fixed end is relatively stable and almost no significant deflection change occurs. At this time, only a local bending resistance performance data can be obtained, which is difficult to comprehensively reflect the actual performance of the entire insulation board. Summary of the Invention

Then, a hydraulic folding plate component and a multi-point pressure detection component cause the insulation board to undergo deflection deformation and complete the detection of the bending performance.

The hydraulic folding plate component 7 is used to lift one end of the polystyrene insulation board upward after the polystyrene insulation board is fixed by the single-cylinder facing clamping plate component 5. A PLC control panel 9 is installed on the outer wall of one side of the looped frame 1.

[0019] Embodiment 2 is based on Embodiment 1 and is given by Figure 5 and Figure 6Given that the front positioning component 2 includes a convex long beam 201 fixed at one side edge position of the top end of the looped frame 1, a sunken groove 204 arranged inside the convex long beam 201, and a Z-axis double-rod cylinder 202 installed on the outer wall of one side of the convex long beam 201. A pressing arm 203 is installed at the bottom end of the piston rod of the Z-axis double-rod cylinder 202. The length extension directions of the convex long beam 201 and the pressing arm 203 are parallel to the length extension direction of the square-mouth connecting beam 3. The input ends of the front positioning component 2, the reduction motor 6, the single-cylinder facing clamping plate component 5, and the hydraulic folding plate component 7 are electrically connected to the output end of the PLC control panel 9. The insulation board to be subjected to the anti-bending performance test is placed on the sunken groove 204, and the insulation board is made to pass through the single-cylinder facing clamping plate component 5. Subsequently, the Z-axis double-rod cylinder 202 is controlled to work by the PLC control panel 9. The pressing arm 203 is driven by the Z-axis double-rod cylinder 202 to move downward until the end of the insulation board is pressed and fixed, ensuring that the polystyrene insulation board is accurately placed at the predetermined position before the test starts, and avoiding test errors caused by position deviation; The double-gear linear traction mechanism 4 includes two symmetric bearing seats 401 installed on the outer wall of one side of the square-mouth connecting beam 3, a longitudinal shaft 402 rotatably installed inside the two bearing seats 401, and helical gears 404 fixed at both ends of the longitudinal shaft 402. A helical rack 405 is fixed on the inner wall of the looped frame 1 at the end position of the longitudinal shaft 402. The helical rack 405 and the helical gear 404 mesh with each other. Synchronous wheels 403 are fixed on one end of the longitudinal shaft 402 and the drive shaft of the reduction motor 6. A multi-wedge belt is wound between the two synchronous wheels 403. A convex portion 301 connected to the single-cylinder facing clamping plate component 5 is installed on the outer wall of the square-mouth connecting beam 3 on one side of the reduction motor 6.

Then, the reduction motor 6 drives the longitudinal shaft 402 and the helical gear 404 to rotate through the synchronous wheel 403. Then, the helical gear 404 drives components such as the square-mouth connecting beam 3, the reduction motor 6, and the single-cylinder facing clamping plate component 5 to move along the extension direction of the helical rack 405, changing the clamping position of the single-cylinder facing clamping plate component 5 on the insulation board, so that the deformation position of the insulation board changes when the hydraulic folding plate component 7 operates; The use of the reduction motor 6 and the double-gear linear traction mechanism 4 can quickly and accurately adjust the position of the clamping plate component, allowing the tester to complete multiple tests in a shorter time and obtain more data.

[0020] Example 3, on the basis of Example 2, by Figure 7 、 Figure 9Given that the single-cylinder opposing clamping plate assembly 5 includes two side plates 501 fixed to the outer wall of the square-mouth connecting beam 3 on the side away from the front positioning assembly 2, an upper hollow U-shaped pressing plate frame 502, a lower hollow U-shaped pressing plate frame 503 symmetrically and slidably installed on the opposite outer walls of the two side plates 501, and a gear-rack opposing pulling structure 505 installed on the outer wall of one of the side plates 501 for connecting the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503. A second cylinder 504 for pushing the upper hollow U-shaped pressing plate frame 502 to lift in the Z-axis direction is installed at the top of one of the side plates 501. The outer wall of one side of the side plate 501 is fixedly connected to the outer wall of one side of the square-mouth connecting beam 3. A gap portion for the polystyrene insulation board to pass through is provided between the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503. The gear-rack opposing pulling structure 505 includes a gear shaft 506 rotatably installed on the outer wall of one of the side plates 501 and racks 507 fixed to the same-side outer walls of the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503. The two racks 507 are parallel to each other and both mesh with the gear shaft 506. The hydraulic folding plate assembly 7 is located on the left side of the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503; The insulation board passes through the gap between the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503, and then the second cylinder 504 drives the upper hollow U-shaped pressing plate frame 502 to move downward. At this time, since the lower hollow U-shaped pressing plate frame 503 is connected to the upper hollow U-shaped pressing plate frame 502 through the gear-rack opposing pulling structure 505, the lower hollow U-shaped pressing plate frame 503 moves upward under the connection of the gear-rack opposing pulling structure 505. Subsequently, the upper hollow U-shaped pressing plate frame 502 and the lower hollow U-shaped pressing plate frame 503 approach each other and clamp the insulation board. Through the design of opposing clamping, a uniform clamping force is provided, so that the insulation board is bent by the hydraulic folding plate assembly 7 in the front area of the single-cylinder opposing clamping plate assembly 5.

[0021] Embodiment 4, based on Embodiment 3, Figure 8 Given that a relatively large bending force is generated by the hydraulic folding plate assembly 7, and at the same time, a stable application speed is maintained to reduce the impact on the material. The hydraulic folding plate assembly 7 includes a slope frame 701 provided on one side inside the looped frame 1, two swing arms 704 hingedly installed at the top of the slope frame 701, and a hydraulic cylinder 702 hingedly installed on the other side at the top of the slope frame 701. A regulator 703 for movably connecting with the outer wall of one side of the swing arm 704 is installed at the top of the piston rod of the hydraulic cylinder 702. The multi-point pressure detection assembly 8 is movably installed between the two swing arms 704, and a hollow column 705 is bolted to the top of the swing arm 704; The regulator 703 includes a number of linear equally-spaced internal-threaded convex shafts fixed on the outer wall of one side of the swing arm 704 and a straight-groove type retaining plate bolted together at one end of a number of internal-threaded convex shafts. The top end of the piston rod of the hydraulic cylinder 702 is fixed with a spherical eye joint, and the spherical eye joint and one of the internal-threaded convex shafts are sleeved. The multi-point pressure detection assembly 8 includes a support arm 801 movably installed between two hollow columns 705 and a number of pressure sensors 802 installed inside the support arm 801; The hydraulic cylinder 702 pushes the regulator 703, the swing arm 704 and the hollow column 705 to deflect. At this time, the pressure sensor 802 is in continuous contact with the lower surface of the insulation board, and the hydraulic cylinder 702 gradually applies a thrust force to cause the insulation board to undergo deflection deformation. The amount of deflection deformation in this process is proportional to the pressure value detected by the pressure sensor 802. By monitoring multiple points through the multi-point pressure detection assembly 8, the response of the insulation board during the force-bending process can be better understood, and potential weaknesses or defects can be identified.

[0022] When the embodiment of the present application is in use, check whether the structure of the looped frame 1 is stable to ensure that there are no loose or damaged components. Check whether the functions of the front positioning component 2 are normal to ensure accurate positioning when fixing the polystyrene insulation board. In addition, it is also necessary to check the operation of the reduction motor 6 and the double-gear linear traction mechanism 4 to ensure its smooth movement. Select multiple polystyrene insulation boards to be detected, check their sizes and appearances to ensure there are no obvious defects or damages, and record the specifications and models of the insulation boards according to the detection standards for subsequent data analysis and recording. Place the polystyrene insulation board on the looped frame 1 and make the insulation board pass through the single-cylinder opposing clamping plate assembly 5. Use the front positioning component 2 to fix one end of the insulation board to ensure that it will not be displaced during the detection process and avoid detection errors caused by position deviation. Operate the reduction motor 6 using the PLC control panel 9 to start the double-gear linear traction mechanism 4, so that the single-cylinder opposing clamping plate assembly 5 moves along the length direction of the insulation board. At this time, according to the detection requirements, adjust the position of the single-cylinder opposing clamping plate assembly 5 in the length direction of the insulation board for subsequent force detection, and the staff should pay attention to observing the movement of the clamping plate assembly to ensure that it reaches the predetermined position smoothly. When the single-cylinder opposing clamping plate assembly 5 reaches the predetermined position, the staff needs to issue an instruction through the PLC control panel 9 to start the single-cylinder opposing clamping plate assembly 5 to fix the insulation board. At this time, the pressure of the single-cylinder opposing clamping plate assembly 5 should be applied evenly to avoid local damage to the insulation board. After the fixation is completed, the staff needs to check the fixation of the clamping plate again to ensure that the insulation board is stable and immovable. After the insulation board is fixed, the staff starts the hydraulic folding plate assembly 7 through the PLC control panel 9, sets the folding parameters through the PLC control panel 9, such as the applied force and the folding angle, and the hydraulic system connected to the hydraulic folding plate assembly 7 will gradually apply pressure according to the set parameters to cause the insulation board to deflect. During the process of applying pressure, the multi-point pressure detection component 8 monitors the deflection change and the pressure degree of the insulation board in real time, and records the pressure data under different deflection folding conditions through the PLC control panel 9. After the detection of this insulation board is completed, the staff removes it and loads another insulation board workpiece into the device according to the same steps. Subsequently, change the action position of the single-cylinder opposing clamping plate assembly 5 and continue the detection of the bending deflection. In this way, by changing the position of the single-cylinder opposing clamping plate assembly 5, multiple areas of the insulation board can participate in the force detection process. After the detection is completed, the staff needs to clean and maintain the device and organize the detection results into a report, including the detection process, data analysis, and conclusion.
