Description

Technical Field

[0001] The present invention relates to the technical field of wall panel strength detection, in particular to a prefabricated building wall panel strength detection mechanism. Background Art

[0002] Wall panels are needed in the field of construction. With the development of technology, there are more and more types of wall panels, including earthquake-resistant wall panels. However, during the production process of earthquake-resistant wall panels, their strength needs to be tested. At this time, a seismic strength testing device for wall panels used in construction is needed.

[0003] When testing wall panels, to ensure the accuracy of the test, a concrete pedestal needs to be poured at the bottom of the wall panel for fixing to the top of the mechanism. However, during the test, the connection between the pedestal and the wall panel is close to the vibration mechanism, and the concrete solidified at different times has poor bearing capacity. This causes the connection position to be subjected to greater pressure, and eventually the connection position will break, resulting in deviations in the test data. To address the above problems, the following solutions are proposed. Summary of the Invention

[0008] Preferably, the support assembly includes a torsion spring 1 fixedly connected to the inner wall of the second rotating frame, and an end of the torsion spring 1 away from the second rotating frame is fixedly connected to the inner wall of the first rotating frame; When the outer wall of the second end of the rotating frame contacts the wall, the rotating frame 2 will no longer rotate downward, while the driving rod continues to rotate, the torsion spring 1 will generate torsion and accumulate potential energy.

[0009] Preferably, the support assembly further comprises a second torsion spring fixedly connected to the inner wall of the rotating frame 1, wherein one end of the second torsion spring away from the rotating frame 1 is fixedly connected to the outer wall of the rotating plate 1; When the driving rod drives the rotating plate 1 to rotate, the rotating plate 1 drives the rotating frame 1 to rotate synchronously through the torsion spring 2, and the rotating frame 1 drives the rotating frame 2 to rotate synchronously through the torsion spring 1.

[0010] Preferably, the sliding assembly includes a through hole formed on the inner wall of the chassis; The snap assembly will completely pass through the through hole, and when the device is in a stationary state, the rotating frame 1 will be inside the rotating frame 2. At this time, the back of the rotating frame 1 will contact the side wall of the snap assembly and force the rack to be pressed away from the outer wall of the sliding block.

[0011] Preferably, the linkage assembly includes a rotating frame rotatably connected to an end of the push rod away from the contact plate, and a side wall of the rotating frame is fixedly connected to a side wall of the sliding block; When the contact plate contacts the outer wall of the wall panel, the contact plate is pressed to rotate around the connection point, and forces the rotating frame and the sliding block to slide along the inner wall of the sliding groove 1 through the push rod.

[0013] Preferably, the buckle assembly includes a pressure plate fixedly connected to the side wall of the rack, and the pressure plate is slidably connected to the inner wall of the through hole; When the rotating frame 1 is completely in contact with the inner wall of the rotating frame 2, the side wall of the rotating frame 1 will press the pressure plate, so that the pressure plate and the rack are away from the gear block, and the spring 2 is in a compressed state.

[0014] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem that the bearing platform will be subjected to excessive pressure during the test, causing damage to the wall panel. A clamping mechanism is set inside the equipment. The CNC motor drives the driving rod to continue to rotate, and the driving rod will drive the rotating plate 1 to continue to rotate downward. At this time, since the rotating frame 2 cannot rotate downward, the outer wall of the rotating frame 1 will separate from the inner wall of the rotating frame 2, presenting the following Figure 5 When the rotating frame 1 contacts the outer wall of the wall panel, the rotating plate 1 continues to rotate downward, and the rotating frame 1 will also contact the outer wall of the wall panel, eventually forming a Figure 1 The state changes to Figure 2 The staff then installed the bolts to Figure 6 The position of the middle U limits the rotation of the rotating frame 2, and the base frame will swing left and right due to the influence of the bottom swing machine. At this time, the rotating frame 1 and the rotating frame 2 transmit the swing force generated by the base frame to the wall panel position. Through the application of the above components, the equipment increases the pressure area of the wall panel during actual detection, avoiding the vibration generated by the swing machine directly acting on the connection between the base and the equipment, resulting in a decrease in measurement accuracy.

[0015] (2) The present invention utilizes the characteristics of the above-mentioned rotating frame 2 and rotating frame 1 rotating downward, and a contact plate is provided inside the device, wherein the rotating frame 1 and the rotating frame 2 are both rotatably connected to the contact plate at one end away from the bottom frame. When the rotating frame 2 rotates downward, it will drive the contact plate to contact the outer wall of the wall panel. Since the pressure required for the torsion spring 1 and the torsion spring 2 to produce deformation is much greater than that of the spring 1, when the rotating frame 2 rotates downward, the contact plate will rotate around the connection point as the center. At this time, the contact plate will drive the rotating frame and the sliding block to slide downward along the inner wall of the slide groove 1 through the push rod, so that the contact plate is tightly attached to the outer wall of the wall panel. Figure 3 The state of F changes to Figure 2 In the middle G state, the force-bearing area of the rotating frame 2 and the rotating frame 1 is increased by applying the above components, so as to avoid cracks in the contact position between the wall and the rotating frame 2 and the rotating frame 1 due to excessive force due to the small contact area between the end of the rotating frame 2 and the wall during equipment inspection.

[0016] (3) The present invention utilizes the characteristic that the rotating frame 1 will move away from the inner wall of the rotating frame 2 during operation, and a pressure plate is provided inside the device. Among them, since the pressure required for the deformation of the torsion spring 1 and the torsion spring 2 is much greater than that of the spring 1, the rotating frame 1 can continue to rotate downward under the drive of the rotating plate 1 and the torsion spring 2 only when the contact plate is completely in close contact with the outer wall of the wall panel and the rotating frame 2 cannot move downward again. As the rotating frame 1 moves away from the inner wall of the base frame, the rack will contact the outer wall of the sliding block under the push of the spring 2, limiting the sliding of the sliding block. At this time, the sliding block cannot move downward, which will limit the rotation of the contact plate. Through the application of the above components, it is avoided that the contact plate rotates due to the left and right swing of the wall panel during the operation of the device, causing the wall panel to swing significantly.

[0017] (4) The present invention utilizes the application of a clamping mechanism and an adapting mechanism, so that the device can adapt to the detection of wall panels of various thicknesses, and the corresponding rotating frame 1 and rotating frame 2 driven by two CNC motors rotate downward. Since the left and right sides rotate downward at the same rate, the force positions at both ends of the wall panel are the same, which effectively avoids the force position deviation caused by the different pressure positions at both ends of the wall when the wall swings left and right, resulting in cracks in the wall.

[0023] The clamping mechanism 1 comprises: Support assembly 11, support assembly 11 is fixedly connected to the outer wall of driving rod 17 through a clamp; The clamping member includes a rotating plate 111 fixedly connected to the outer wall of the driving rod 17, a rotating frame 112 rotatably connected to the outer wall of the driving rod 17, and a rotating frame 2 113 rotatably connected to the outer wall of the driving rod 17; The sliding assembly 12 is opened on the inner wall of the rotating frame 112 through a limiting member; The limiting member includes a first slide groove 121 formed on the side wall of the second rotating frame 113, and a second slide groove 123 formed on the inner wall of the first slide groove 121; Before use, first fix the base frame 13 on a stable ground, then bolt the building wall panel to the top of the load-bearing plate 14, connect the power of the CNC motor 16 at both ends, and force the CNC motor 16 to drive the rotating plate 111 to rotate through the driving rod 17; The side wall of the first rotating frame 112 is also provided with a first sliding groove 121 and a second sliding groove 123 , and the first rotating frame 112 and the second rotating frame 113 operate in the same manner.

[0024] Adaptation Agency 2 includes: The linkage assembly 21 is rotatably connected to the top of the second rotating frame 113 through a contact member; The contact member includes a contact plate 211 rotatably connected to the top of the second rotating frame 113 , and an end of the contact plate 211 away from the second rotating frame 113 is rotatably connected to a push rod 212 ; The buffer assembly 22 is slidably connected to the inner wall of the slide groove 121 through a sliding member; The sliding member includes a sliding block 221 slidably connected to the inner wall of the sliding groove 121, and a tooth block 222 is fixedly connected to the side wall of the sliding block 221; In a normal state, there is a certain distance between the sliding block 221 and the limiting mechanism 3 , so that the sliding block 221 can slide up and down along the inner wall of the sliding groove 121 .

[0025] Restriction agencies 3 include: The buckle assembly 31 is slidably connected to the inner wall of the second slide groove 123 through a limiting member; The limiting member includes a rack 311 slidably connected to the inner wall of the second slide groove 123, and a plurality of second springs 312 are fixedly connected to the side wall of the rack 311; In a normal state, the tooth block 222 does not contact the outer wall of the rack 311 . When the rack 311 moves outward and contacts the outer wall of the tooth block 222 , the rack 311 will restrict the sliding of the sliding block 221 .

[0026] For example 2, please refer to Figure 3-Figure 11 The present invention is a prefabricated building wall panel strength testing mechanism. Based on Example 1, the support assembly 11 includes a torsion spring 114 fixedly connected to the inner wall of the second rotating frame 113. The end of the torsion spring 114 away from the second rotating frame 113 is fixedly connected to the inner wall of the first rotating frame 112. When the outer wall of the end of the second rotating frame 113 contacts the wall, the second rotating frame 113 will no longer rotate downward, while the driving rod 17 continues to rotate, and the torsion spring 114 will be twisted and accumulate potential energy; The rotating plate 111 drives the rotating frame 112 to rotate in the same direction through the torsion spring 115, and the rotating frame 112 drives the rotating frame 2 113 to rotate in the same direction through the torsion spring 114. During this process, the outer wall of the rotating frame 2 113 will contact the outer wall of the wall panel. Then, the CNC motor 16 drives the driving rod 17 to continue to rotate, and the driving rod 17 will drive the rotating plate 111 to continue to rotate downward. At this time, since the rotating frame 2 113 cannot rotate downward, the outer wall of the rotating frame 112 will separate from the inner wall of the rotating frame 2 113, presenting the following Figure 5 status.

[0027] The support assembly 11 further includes a second torsion spring 115 fixedly connected to the inner wall of the first rotating frame 112, and an end of the second torsion spring 115 away from the first rotating frame 112 is fixedly connected to the outer wall of the first rotating plate 111; When the driving rod 17 drives the rotating plate 111 to rotate, the rotating plate 111 drives the rotating frame 112 to rotate synchronously via the torsion spring 115, and the rotating frame 112 drives the rotating frame 2 113 to rotate synchronously via the torsion spring 114. When the rotating frame 112 contacts the outer wall of the wall panel, the rotating plate 111 continues to rotate downward, and the rotating frame 112 will also contact the outer wall of the wall panel, and finally form Figure 1 The state changes to Figure 2 The staff then installed the bolts to Figure 6 The position of the middle U limits the rotation of the rotating frame 2 113, and the base frame 13 will swing left and right under the influence of the bottom swing machine. At this time, the rotating frame 112 and the rotating frame 2 113 transmit the swing force generated by the base frame 13 to the wall panel position. Through the application of the above components, the equipment increases the pressure area of the wall panel during actual testing, avoiding the vibration generated by the swing machine directly acting on the connection between the base and the equipment, resulting in a decrease in measurement accuracy.

[0028] The sliding assembly 12 includes a through hole 122 formed on the inner wall of the base frame 13; The snap assembly 31 will completely pass through the through hole 122, and when the device is in a stationary state, the rotating frame 112 will be inside the rotating frame 2 113. At this time, the back of the rotating frame 112 will contact the side wall of the snap assembly 31 and force the rack 311 to be pressed away from the outer wall of the sliding block 221.

[0029] The linkage assembly 21 includes a rotating frame 213 rotatably connected to an end of the push rod 212 away from the contact plate 211 , and a side wall of the rotating frame 213 is fixedly connected to a side wall of the sliding block 221 ; When the contact plate 211 contacts the outer wall of the wall panel, the contact plate 211 is pressed and rotates around the connection point, and the push rod 212 forces the rotating frame 213 and the sliding block 221 to slide along the inner wall of the sliding groove 121; By utilizing the characteristics of the downward rotation of the above-mentioned rotating frame 213 and the rotating frame 112, a contact plate 211 is provided inside the device, wherein the rotating frame 112 and the rotating frame 213 are rotatably connected to the contact plate 211 at one end away from the bottom frame 13. When the rotating frame 213 rotates downward, the contact plate 211 will be driven to contact the outer wall of the wall panel. Since the pressure required for the torsion spring 114 and the torsion spring 115 to produce deformation is much greater than the spring 1 223, when the rotating frame 213 rotates downward, the contact plate 211 will rotate around the connection point as the center. At this time, the contact plate 211 will drive the rotating frame 213 and the sliding block 221 to slide downward along the inner wall of the slide groove 121 through the push rod 212, so that the contact plate 211 is tightly attached to the outer wall of the wall panel. Figure 3 The state of F changes to Figure 2In the middle G state, the force-bearing area of the rotating frame 2 113 and the rotating frame 1 112 is increased by applying the above components, so as to avoid cracks in the contact position between the wall and the rotating frame 2 113 and the rotating frame 1 112 due to excessive force due to the small contact area between the end of the rotating frame 2 113 and the wall during equipment inspection.

[0030] The buffer assembly 22 includes a spring 1 223 fixedly connected to the top of the rotating frame 213, and an end of the spring 1 223 away from the rotating frame 213 is fixedly connected to the inner wall of the sliding groove 121; When the sliding block 221 and the rotating frame 213 slide downward synchronously, the spring 1 223 will be stretched by the tension and accumulate mechanical power. By utilizing the characteristic that the rotating frame 112 will move away from the inner wall of the rotating frame 2 113 during operation, a pressure plate 313 is provided inside the device. Among them, since the pressure required for the deformation of the torsion spring 114 and the torsion spring 215 is much greater than the spring 1 23, only when the contact plate 211 is completely in close contact with the outer wall of the wall panel and the rotating frame 2 113 cannot move downward again, the rotating frame 112 can continue to rotate downward under the drive of the rotating plate 111 and the torsion spring 2 115. As the rotating frame 112 moves away from the inner wall of the base frame 13, the rack 311 will contact the outer wall of the sliding block 221 under the push of the spring 2 312, limiting the sliding of the sliding block 221. At this time, the sliding block 221 cannot move downward, which will limit the rotation of the contact plate 211. Through the application of the above components, the left and right swing of the wall panel during operation of the device is avoided, causing the contact plate 211 to rotate, resulting in a large-scale effective swing of the wall panel.

[0031] The buckle assembly 31 includes a pressure plate 313 fixedly connected to the side wall of the rack 311, and the pressure plate 313 is slidably connected to the inner wall of the through hole 122; When the first rotating frame 112 is completely in contact with the inner wall of the second rotating frame 113, the side wall of the first rotating frame 112 presses the pressure plate 313, causing the pressure plate 313 and the rack 311 to move away from the gear block 222. At this time, the second spring 312 is in a compressed state. By utilizing the clamping mechanism 1 and the adapting mechanism 2, the equipment can adapt to the detection of wall panels of various thicknesses, and the corresponding rotating frame 1 112 and the rotating frame 2 113 driven by the two CNC motors 16 rotate downward. Since the downward rotation rates of the left and right sides are equal, the force positions at both ends of the wall panel are the same, which effectively avoids the force position deviation caused by the different pressure positions at both ends of the wall when the wall swings left and right, resulting in cracks in the wall.

[0032] A specific application of this embodiment is as follows: before use, the base frame 13 is first fixed on a stable ground, and then the building wall panel is bolted to the top of the load-bearing plate 14, and the power supply of the CNC motor 16 at both ends is turned on, forcing the CNC motor 16 to drive the rotating plate 111 to rotate through the driving rod 17; At this time, the rotating plate 111 drives the rotating frame 112 to rotate in the same direction through the torsion spring 115, and the rotating frame 112 drives the rotating frame 2 113 to rotate in the same direction through the torsion spring 114. During this process, the outer wall of the rotating frame 2 113 will contact the outer wall of the wall panel. Then, the CNC motor 16 drives the driving rod 17 to continue to rotate, and the driving rod 17 will drive the rotating plate 111 to continue to rotate downward. At this time, since the rotating frame 2 113 cannot rotate downward, the outer wall of the rotating frame 112 will separate from the inner wall of the rotating frame 2 113, presenting as shown in the figure. Figure 5 When the rotating frame 112 contacts the outer wall of the wall panel, the rotating plate 111 continues to rotate downward, and the rotating frame 112 will also contact the outer wall of the wall panel, and finally form Figure 1 The state changes to Figure 2 The staff then installed the bolts to Figure 6 The position of the middle U limits the rotation of the rotating frame 2 113, and the base frame 13 will swing left and right under the influence of the bottom swing machine. At this time, the rotating frame 112 and the rotating frame 2 113 transmit the swing force generated by the base frame 13 to the wall panel position. Through the application of the above components, the equipment increases the pressure area of the wall panel during actual testing, avoiding the vibration generated by the swing machine directly acting on the connection between the base and the equipment, resulting in a decrease in measurement accuracy.

[0033] By utilizing the characteristics of the downward rotation of the above-mentioned rotating frame 213 and the rotating frame 112, a contact plate 211 is provided inside the device, wherein the rotating frame 112 and the rotating frame 213 are rotatably connected to the contact plate 211 at one end away from the bottom frame 13. When the rotating frame 213 rotates downward, the contact plate 211 will be driven to contact the outer wall of the wall panel. Since the pressure required for the torsion spring 114 and the torsion spring 115 to produce deformation is much greater than the spring 1 223, when the rotating frame 213 rotates downward, the contact plate 211 will rotate around the connection point as the center. At this time, the contact plate 211 will drive the rotating frame 213 and the sliding block 221 to slide downward along the inner wall of the slide groove 121 through the push rod 212, so that the contact plate 211 is tightly attached to the outer wall of the wall panel. Figure 3 The state of F changes to Figure 2 In the middle G state, the force-bearing area of the rotating frame 2 113 and the rotating frame 1 112 is increased by applying the above components, so as to avoid cracks in the contact position between the wall and the rotating frame 2 113 and the rotating frame 1 112 due to excessive force due to the small contact area between the end of the rotating frame 2 113 and the wall during equipment inspection.

[0034] By utilizing the characteristic that the rotating frame 112 will move away from the inner wall of the rotating frame 2 113 during operation, a pressure plate 313 is provided inside the device. Among them, since the pressure required for the deformation of the torsion spring 114 and the torsion spring 215 is much greater than the spring 1 23, only when the contact plate 211 is completely in close contact with the outer wall of the wall panel and the rotating frame 2 113 cannot move downward again, the rotating frame 112 can continue to rotate downward under the drive of the rotating plate 111 and the torsion spring 2 115. As the rotating frame 112 moves away from the inner wall of the base frame 13, the rack 311 will contact the outer wall of the sliding block 221 under the push of the spring 2 312, limiting the sliding of the sliding block 221. At this time, the sliding block 221 cannot move downward, which will limit the rotation of the contact plate 211. Through the application of the above components, the left and right swing of the wall panel during operation of the device is avoided, causing the contact plate 211 to rotate, resulting in a large-scale effective swing of the wall panel.

[0035] By utilizing the clamping mechanism 1 and the adapting mechanism 2, the equipment can adapt to the detection of wall panels of various thicknesses, and the corresponding rotating frame 1 112 and the rotating frame 2 113 driven by the two CNC motors 16 rotate downward. Since the downward rotation rates of the left and right sides are equal, the force positions at both ends of the wall panel are the same, which effectively avoids the force position deviation caused by the different pressure positions at both ends of the wall when the wall swings left and right, resulting in cracks in the wall.

[0036] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention.
