Description

Technical Field

[0001] The invention relates to the technical field of strength testing, and in particular to a curtain wall performance testing device. Background Art

[0002] Compared with traditional building exterior walls, curtain walls have higher thermal insulation, heat insulation and sound insulation properties, and also have certain decorative properties. Curtain walls are divided into glass curtain walls and metal (aluminum veneer) curtain walls according to their materials. Since curtain walls are located on the exterior walls of buildings, their bearing strength needs to be tested to ensure that they can meet the wind pressure resistance requirements.

[0003] When conducting a compression test on a curtain wall, since direct testing with wind force has high requirements on the equipment on the one hand and on the openness of the test site on the other hand, the existing technology mostly uses static pressure testing when testing.

[0004] After searching, the Chinese patent was announced as CN118706582A, which discloses a glass curtain wall performance detection device, including a workbench, a placing table fixedly connected to the upper surface of the workbench, the placing table is rectangular, a placing frame is installed on the upper surface of the placing table, the placing frame is rectangular and annular, a connecting mechanism is provided between the placing frame and the placing table for the convenience of the operator to install and disassemble the placing frame, an annular groove is provided on the upper surface of the placing frame, one side of the annular groove is connected to the inner wall of the placing frame, a locking mechanism is provided on the inner wall of the annular groove, a bracket is installed on the workbench, a driving cylinder is fixedly connected to the bracket, a pressure block is fixedly connected to the output end of the driving cylinder, and a pressure sensor is fixedly connected to the pressure block.

[0005] The above patent has the following deficiencies: it uses the pressure block in the middle to apply pressure, which makes the pressure on the curtain wall concentrated in the center, while in actual use, the entire surface of the curtain wall will be subjected to wind pressure, which leads to poor fit between the test conditions and the actual conditions, and the credibility of the test results is also low. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a curtain wall performance detection device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] Further: The position - adjusting component includes at least two lead screws movably inserted into the inner wall of the sliding arm. The bottom of the lead screw is rotatably connected to the pressure sensor. A key - shaped groove is provided on the side wall of the connecting plate, and a key - shaped protrusion in clearance fit with the key - shaped groove is provided on the inner wall of the sliding arm. A gear two is rotatably connected to the top outer wall of the sliding arm outside the lead screw. The gear two is thread - connected to the outer wall of the lead screw, and the same gear three is meshed with the inner sides of the gear twos in the same group. A micro - motor is fixedly installed on the bottom outer wall of the sliding arm through a bolt. The output shaft of the micro - motor penetrates through the sliding arm and is fixed to the inner wall of the gear three.

[0014] Based on the foregoing solution: The lifting and pressure - applying part includes a main cylinder, a piston, and a piston rod. The main cylinder is fixedly installed on the top outer wall of the support frame through a bolt. The piston is slidably connected to the inner wall of the main cylinder.

[0015] In a better solution among the foregoing solutions: An oil nozzle and an adjustable pressure - relief valve are respectively provided on the top outer wall of the main cylinder.

[0016] As a further solution of the present invention: A branch cylinder is welded and communicated with one side of the top of the main cylinder. A vibration plug and a cavity plug are respectively slidably connected to the inner walls at both ends of the branch cylinder. A vibration block is wrapped by an anti - wear sleeve on the inner wall of the cavity plug. One side of the vibration block is connected to a two - way oil pump through a connecting rod.

[0017] Meanwhile, one side of the two - way oil pump is connected to the oil nozzle, the other side of the two - way oil pump is connected to an oil tank, and the pressure - relief end of the adjustable pressure - relief valve is connected to the oil tank.

[0018] As a preferred embodiment of the present invention: the supporting and fixing assembly includes two connecting frames, one of which is fixed to one side of the detection platform, and the bottom of the other connecting frame is fixed with a slider by bolts, the bottom of the slider is slidably connected to a slide rail, and the slide rail is fixed to the top outer wall of the detection platform by bolts.

[0020] As a more preferred solution of the present invention: the inner wall of the slide and the inner wall of the slider are both provided with locking bolts for locking the position of the slide and the slider.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention, by configuring the pressure head as a combination of multiple cavity shells, and the inner wall of each cavity shell is provided with two sliding arms, can utilize the rotation of the cavity shell and the position adjustment of the sliding arm to enable multiple contact pressure plates to uniformly contact and apply pressure to the surface of the curtain wall.

On the other hand, targeted adjustments can be made to curtain walls with different surface areas.

[0023] 2. The present invention, by setting a pressure sensor, can indirectly sense the force of the contact rubber plate on the curtain wall, so that the total load of the curtain wall can be obtained by summing. At the same time, by setting a position adjustment component, it can adjust the height of multiple contact pressure plates on the one hand, and on the other hand, it can also adjust the height of the contact pressure plate according to the load difference during actual detection, so that the load at each contact pressure plate is the same, thereby ensuring the uniformity of the force on the entire curtain wall. At the same time, combined with the sliding of the sliding arm, the positions of multiple contact pressure plates can be different, and combined with adjusting the loads of different pressure plates, the different bearing and stress conditions of the curtain wall under different natural or meteorological conditions can be effectively simulated, which can achieve all-round and comprehensive detection, and provide a basis for the manufacture, processing and improvement of the curtain wall.

[0024] 3. The present invention, on the basis of setting a main cylinder, a piston, a piston rod and the like for fixed pressure, additional components such as a support cylinder, a vibration plug, and a cavity plug are provided, which can realize the transmission of load fluctuations to the curtain wall during detection, so that the stress frequency and stress condition of the curtain wall are more in line with the actual working scene, and the detection result is objective and true. In addition, the power of the load fluctuation comes from the working vibration of the two-way oil pump, so that on the one hand, the "waste energy" of the vibration of the two-way oil pump can be used to drive the load fluctuation, and on the other hand, the anti-wear sleeve and the air in the inner cavity of the support cylinder can be used to absorb the vibration of the two-way oil pump to a certain extent.

[0025] 4. In the present invention, by providing components such as a connecting frame and a sliding frame, the length and width of the fixed limit for the curtain wall can be adjusted by the sliding of the connecting frame relative to the detection table and the sliding of the sliding frame relative to the connecting frame, so as to be adaptable to the fixed limit of curtain walls of different sizes.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Embodiment 1:

[0039] A curtain wall performance detection device, such as Figures 1 - 9 As shown, it includes a testing platform 1, the top of which is provided with a supporting fixing assembly 5 for fixing and supporting the curtain wall, a supporting frame 2 is fixed to the top of one side of the testing platform 1 by bolts, and one end of the top of the supporting frame 2 is connected to a pressure head 4 through a lifting and pressing part 3.

[0040] The pressure head 4 is composed of at least two cavity shells 6 that are connected by rotation from top to bottom in sequence. The inner wall of each cavity shell 6 is slidably connected to two symmetrical sliding arms 7. A group of position adjustment components 8 are provided at the ends of the sliding arms 7. A group of contact pressure plates 9 are provided at the bottom of each group of position adjustment components 8 and the bottom of the lowest cavity shell 6, and multiple groups of contact pressure plates 9 are located at the same height.

[0041] The inner wall of each cavity shell 6 is rotatably connected to a gear 11, and the gear 11 is located at the rotation center of the two sliding arms 7 in the same group, and the inner wall of the sliding arm 7 is provided with teeth 10 meshing with the outer wall of the gear 11.

[0042] When this device is in use, the curtain wall can be supported and fixed by the support and fixing component 5, and the angles of multiple cavity shells 6 and the positions of the sliding arms 7 relative to the cavity shells 6 can be adjusted according to the size and cross-sectional shape of the curtain wall, so that the multiple sliding arms 7 are evenly and equiangularly arrayed. Then, the rotational friction force between the cavity shells 6 and the sliding friction force between the sliding arms 7 and the cavity shells 6 are used to fix it naturally. Then, the entire pressure head 4 is driven to descend by the lifting and pressing part 3 until the contact pressure plate 9 contacts the surface of the curtain wall and continues to apply the set load force to the curtain wall. Whether the curtain wall is deformed or broken can be observed.

[0043] In this device, by setting the pressure head 4 as a combination of multiple cavity shells 6, and two sliding arms 7 are arranged on the inner wall of each cavity shell 6, the rotation of the cavity shell 6 and the position adjustment of the sliding arms 7 can be used to make the multiple contact pressure plates 9 evenly contact and press on the surface of the curtain wall. On the one hand, it can make the force on the curtain wall relatively uniform and increase the fit with the actual working conditions. On the other hand, it can also be adjusted specifically to fit curtain walls with different surface areas.

[0044] To solve the problems of adjustment and pressure sensing; as Figure 5 shown, the contact pressure plate 9 includes a connecting plate 17 and a contact rubber plate 18 movably sleeved outside the connecting plate 17. A pressure sensor 19 is fixed on the bottom outer wall of the connecting plate 17, and the pressure sensing end of the pressure sensor 19 is in contact and cooperation with the contact rubber plate 18.

[0045] The position adjustment component 8 includes at least two lead screws 14 movably inserted into the inner wall of the sliding arm 7. The bottom of the lead screw 14 is rotatably connected to the pressure sensor 19. A key-shaped groove 12 is formed in the side wall of the connecting plate 17, and a key-shaped protrusion that is in clearance fit with the key-shaped groove 12 is arranged on the inner wall of the sliding arm 7. And a second gear 13 is rotatably connected to the top outer wall of the sliding arm 7 outside the lead screw 14. The second gear 13 is threadedly connected to the outer wall of the lead screw 14, and the same group of second gears 13 are meshed with the same third gear 16 on the inner side. A micro motor 15 is fixed to the bottom outer wall of the sliding arm 7 by bolts, and the output shaft of the micro motor 15 penetrates through the sliding arm 7 and is fixed to the inner wall of the third gear 16.

[0046] When the micro motor 15 starts, it can drive the rotation of the third gear 16, thereby driving the rotation of the second gear 13. Since the second gear 13 is in threaded cooperation with the lead screw 14, and the lead screw 14 can only axially move relative to the sliding arm 7 through the cooperation of the key-shaped groove 12 and the key-shaped protrusion and cannot rotate, the rotation of the second gear 13 can drive the axial movement of the key-shaped groove 12, thereby driving the axial movement of the pressure sensor 19 to adjust the height of multiple pressure sensors 19. At the same time, during the test, the pressure sensor 19 can sense the force between the connecting plate 17 and the contact rubber plate 18, thereby indirectly sensing the force of the contact rubber plate 18 on the curtain wall. When the force of the pressure sensors 19 around is greater than or less than the force of the pressure sensors 19 in the middle, it means that the position of the contact rubber plate 18 here is relatively low. At this time, the corresponding micro motor 15 can be controlled to start, so that the connecting plate 17 at this place moves up or down until the readings of the pressure sensors 19 at this place are the same as those of the connecting plate 17 in the middle.

[0047] In this device, by setting the pressure sensor 19, it can indirectly sense the force of the contact rubber plate 18 on the curtain wall, so that the total load of the curtain wall can be obtained by summation. At the same time, by setting the position adjusting component 8, on the one hand, it can adjust the height of multiple contact pressing plate members 9, and on the other hand, it can also adjust the height of the contact pressing plate members 9 according to the load difference during actual detection, so that the load at each contact pressing plate member 9 is the same, thereby ensuring the uniformity of the force of the entire curtain wall. At the same time, combined with the sliding of the sliding arm 7, the positions of multiple contact pressing plate members 9 can also be different. By adjusting the loads of different pressing plate members, different bearing force conditions of the curtain wall under different natural or meteorological conditions can be effectively simulated, achieving a comprehensive and all-round detection, providing a basis for the manufacturing, processing and improvement of the curtain wall.

[0048] To solve the pressure application problem; as Figures 6 - 8 shown, the lifting and pressing part 3 includes a main cylinder 24, a piston 25 and a piston rod 26. The main cylinder 24 is fixed to the outer wall of the top of the support frame 2 by bolts. The piston 25 is slidably connected to the inner wall of the main cylinder 24. The piston rod 26 is fixed to the outer wall of the bottom of the piston 25 by bolts, and the bottom end of the piston rod 26 is fixed to the outer wall of the uppermost cavity shell 6. The top outer wall of the main cylinder 24 is respectively provided with an oil nozzle 21 and an adjustable pressure relief valve 22.

[0049] One side of the top of the main cylinder 24 is welded and communicated with a branch cylinder 20. The inner walls of both ends of the branch cylinder 20 are respectively slidably connected with a vibration plug 23 and a cavity plug 31. The inner wall of the cavity plug 31 is wrapped with a vibration block 28 through an anti-wear sleeve 27. One side of the vibration block 28 is connected with a two-way oil pump 30 through a connecting rod 29. One side of the two-way oil pump 30 is connected to the oil nozzle 21, the other side of the two-way oil pump 30 is connected with an oil tank, and the pressure relief end of the adjustable pressure relief valve 22 is connected to the oil tank.

[0050] When the two-way oil pump 30 starts to deliver the oil in the fuel tank to the oil nozzle 21, the piston 25 will be subjected to a decrease in oil pressure. Until the contact application plate 9 contacts the curtain wall, the two-way oil pump 30 continues to deliver oil to the inner cavity of the main cylinder 24 until the preset load is reached. Then, the adjustable pressure relief valve 22 starts to relieve pressure. At the same time as the pressure relief, the two-way oil pump 30 also starts with a constant operation. At this time, it is in the test state, and the oil relieved by the adjustable pressure relief valve 22 continues to flow back into the fuel tank. At the same time, due to the operation of the two-way oil pump 30, vibrations will occur, and the gas pressure in the inner cavity of the support cylinder 20 will fluctuate, so the gas pressure acting on the vibration plug 23 will also fluctuate. And the vibration plug 23 senses the oil pressure inside the main cylinder 24, which will cause the oil pressure in the main cylinder 24 to fluctuate, resulting in a slight fluctuation in the load received by the curtain wall.

[0051] Since after the curtain wall is actually installed, the wind pressure it receives will show slight fluctuations due to impurities in the air. Based on this:

[0052] On the basis of setting the main cylinder 24, piston 25, piston rod 26, etc. for fixed pressure application, this device adds components such as the support cylinder 20, vibration plug 23, cavity plug 31, etc. It can realize the detection of the load fluctuation transmitted to the curtain wall, so that the stress frequency and stress condition of the curtain wall are more in line with the actual working scenario, making the detection result objective and real. In addition, the power source of the load fluctuation is the working vibration of the two-way oil pump 30. On the one hand, it can utilize the "waste energy" of the vibration of the two-way oil pump 30 to drive the load fluctuation. On the other hand, it can also use the anti-wear sleeve 27 and the air in the inner cavity of the support cylinder 20 to absorb the vibration of the two-way oil pump 30 to a certain extent.

[0053] When the present embodiment is in use, the curtain wall can be supported and fixed by the supporting and fixing assembly 5, and the angles of the plurality of cavity shells 6 and the positions of the sliding arms 7 relative to the cavity shells 6 can be adjusted according to the size and cross-sectional shape of the curtain wall, so that the plurality of sliding arms 7 are arranged evenly and at equal angles, and then the rotational friction between the cavity shells 6 and the sliding friction between the sliding arms 7 and the cavity shells 6 are used to fix them naturally, and then the entire pressure head 4 is driven down by the lifting and lowering pressure part 3 until the contact pressure plate 9 contacts the surface of the curtain wall, and then the set load force is continuously applied to the curtain wall to observe whether the curtain wall is deformed or broken. That is, when the micro motor 15 is started, it can drive the gear three 16 to rotate, thereby driving the gear two 13 to rotate. Since the gear two 13 is threadedly matched with the screw rod 14, and the screw rod 14 can only move axially relative to the sliding arm 7 through the cooperation of the key-shaped groove 12 and the key-shaped protrusion but cannot rotate, the rotation of the gear two 13 can drive the key-shaped groove 12 to move axially, thereby driving the pressure sensor 19 to move axially to adjust the height of the multiple pressure sensors 19. At the same time, during the test, the pressure sensor 19 can sense the force between the connecting plate 17 and the contact rubber plate 18, thereby indirectly sensing the contact The force of the rubber plate 18 on the curtain wall, when the force of the pressure sensors 19 on the surroundings is greater than or less than the force of the pressure sensor 19 in the middle, it means that the contact rubber plate 18 here is relatively low, so that the corresponding micro motor 15 can be controlled to start at this time, so that the connecting plate 17 at this location moves up and moves down together, until the reading of the pressure sensor 19 at this location is the same as that of the connecting plate 17 in the middle, and at the same time, when the two-way oil pump 30 starts to transport the oil in the oil tank to the oil nozzle 21, the piston 25 will be affected by the oil pressure drop until the contact pressure plate 9 contacts the curtain wall, and the two-way oil pump 30 continues to transport oil The liquid flows into the inner cavity of the main cylinder 24 until the preset load is reached, and the adjustable pressure relief valve 22 starts to relieve pressure. At the same time, the two-way oil pump 30 is also normally started. At this time, it is in a testing state, and the oil relieved by the adjustable pressure relief valve 22 continues to flow back to the oil tank. At the same time, the operation of the two-way oil pump 30 will generate vibrations, which will cause the gas pressure in the inner cavity of the support cylinder 20 to fluctuate, thereby causing the gas pressure acting on the vibration plug 23 to fluctuate. The vibration plug 23 is inductively coupled to the oil pressure inside the main cylinder 24, thereby causing the oil pressure in the main cylinder 24 to fluctuate, causing the load on the curtain wall to fluctuate slightly.

The bottom of the slider 34 is slidably connected to a slide rail 32, and the slide rail 32 is fixed to the top outer wall of the inspection table 1 by bolts.
