DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-7 This application is described in further detail.

[0033] Example 1: Reference Figure 1A comprehensive impact resistance detection device for building panels, comprising a fixing mechanism and an impact mechanism, wherein the fixing mechanism comprises a support frame 1, a flip frame 2, an angle adjuster 3 and a clamp 4, wherein the bottom of the support frame 1 is rotatably mounted with the flip frame 2, and the flip frame 2 can flip up and down, and the clamp 4 is arranged on the flip frame 2 for fixing the building panels, and the angle adjuster 3 is arranged between the support frame 1 and the flip frame 2 for controlling the rotation angle of the flip frame 2 (such as the attached Figure 3 As shown), the impact mechanism includes an electric hoist lift 5, a hammer 6 and a toggle 7. A linear module 11 for moving forward and backward is provided on the top of the support frame 1. A mobile frame 12 is fixedly installed on the linear module 11. The electric hoist lift 5 and the toggle 7 are fixedly installed on the mobile frame 12. The electric hoist lift 5 is used to drive the hammer 6 to move up and down to impact the building board. The electric hoist lift 5 includes a reduction motor, a drum 51, a brake and a wire rope 52. The drum 51 is located at the top of the support frame 1. The end of the drum 51 is connected to the reduction motor and the brake. The upper end of the wire rope 52 is fixedly connected to the drum 51. The lower end of the wire rope 52 is fixedly installed with a hammer 6. The toggle 7 is located in the middle of the support frame 1 and is used to toggle the wire rope 52 to make the hammer 6 swing to impact the building board (as shown in the attached figure). Figure 2 shown).

[0034] Through the above technical solution, the working principle of the comprehensive detection device is as follows:

[0035] 1. Fixing mechanism setting: The building board 8 is fixed on the turning frame 2 by the clamp 4, and the turning frame 2 is installed at the bottom of the support frame 1, which can realize up and down turning movement. The rotation angle of the turning frame 2 is controlled by the angle adjuster 3, so as to adjust the position and angle of the board relative to the impact mechanism.

[0036] 2. Impact mechanism composition: The impact mechanism includes an electric hoist lift 5, a hammer 6 and a toggle 7. The electric hoist lift 5 is installed on the linear module on the top of the support frame 1. The linear module can drive the electric hoist lift 5 and the toggle 7 to move forward and backward, which increases the flexibility and application range of the device and facilitates the adjustment of the striking position of the hammer 6 on the building board.

[0037] 3. Working of the electric hoist lift: The reduction motor, drum 51, brake and wire rope 52 in the electric hoist lift 5 work together. The reduction motor can rotate forward and reverse to control the rotation of the drum 51 to wind or release the wire rope 52, thereby realizing the lifting and lowering movement of the hammer 6.

[0038] 4. Hammer impact process: There are two classic impact modes. One is that the angle adjuster 3 adjusts the building board to a vertical state: the toggle 7 is located in the middle of the support frame 1, and by toggling the wire rope 52, the hammer 6 is guided to swing, and the side of the hammer 6 realizes the impact on the surface of the building board. One is that the angle adjuster 3 adjusts the building board to a horizontal state: the electric hoist lift 5 drives the lifting and lowering movement of the hammer 6, and the bottom of the hammer 6 realizes the impact on the surface of the building board. The use of the angle adjuster 3 in conjunction with the linear module allows the hammer 6 to impact the board with different energies and angles. The rotation angle of the flip frame 2 is 0-90 degrees, which can meet the impact requirements of the single side of the board. If the double-sided board is to be impacted, the structure of the flip frame 2 can be designed as a square frame structure, the middle of the square frame is hollowed out, and the hammer can pass through. The side of the square frame is connected to the angle adjuster 3, and the flip frame 2 can achieve a 360-degree rotation range, so that the back of the board can also be impact-resistant.

[0039] This technical solution realizes the automatic impact test of the building board through the automated electric hoist lift 5 and the toggle 7, avoiding the tediousness and inefficiency of manually swinging the sandbag. At the same time, the setting of the flip frame 2 and the angle adjuster 3 makes the angle adjustment of the board convenient and fast, and can perform multi-angle impact resistance tests, thereby improving the accuracy and repeatability of the test.

[0040] Embodiment 2: As attached Figure 4 As shown, the only difference from other embodiments is that the toggle 7 includes an electric push-pull rod 71, a limit frame 72 and a toggle wheel 73. The electric push-pull rod 71 is fixedly installed on the mobile frame horizontally, and can drive the object to move in the horizontal direction. The automatic control of the electric push-pull rod 71 reduces manual operation and improves the experimental efficiency. The limit frame 72 is fixedly installed on the telescopic end of the electric push-pull rod 71, and its function is to limit the movement range of the wire rope. The limit frame 72 is provided with a limit groove 721 for the wire rope 52 to pass through, and the limit groove 721 ensures that the wire rope 52 maintains the correct position and direction during the toggle process. The left end of the limit groove 721 is installed with a toggle wheel 73, which contacts the wire rope 52, and pushes and guides the wire rope 52 through it, thereby controlling the swing of the hammer 6. The toggle wheel 73 can reduce the friction loss of the toggle wire rope 52, and improve the repeatability and accuracy of the experiment.

[0041] During the experiment, the electric push-pull rod 71 performs telescopic movement according to the command of the control system, driving the limit frame 72 and the toggle wheel 73 to move in the horizontal direction. The toggle wheel 73 contacts the steel wire rope 52, and through the steel wire rope, the hammer 6 swings to achieve the impact on the building board. The toggle device 7 is compact in design and has clear functions, and can accurately control the swing amplitude and direction of the hammer 6. The limit frame 72 and the limit slot 721 ensure the stable operation of the steel wire rope 52, and the setting of the toggle wheel 73 realizes the precise control of the swing of the hammer 6.

[0042] A limiting wheel 74 is provided at the right end of the limiting groove 721, and the steel wire rope 52 is located between the limiting wheel 74 and the toggle wheel 73. The limiting wheel 74 is rotatably mounted on the movable wheel seat 741. A distance-adjusting telescopic rod 742 is provided between the movable wheel seat 741 and the limiting frame 72. The distance-adjusting telescopic rod 742 is used to adjust the distance between the limiting wheel 74 and the toggle wheel 73. By adjusting the distance-adjusting telescopic rod 742, the distance between the limiting wheel 74 and the toggle wheel 73 can be accurately controlled, thereby adjusting the tension and toggle effect of the steel wire rope 52, and ensuring that the hammer 6 can hit the building board with appropriate force and angle.

[0043] The toggle switch can be applied to wire ropes of different specifications and different experimental conditions. By adjusting the spacing between the limit wheel 74 and the toggle wheel 73, the swing amplitude and impact force of the hammer 6 can be optimized, and the accuracy and repeatability of the experiment can be improved. In addition, when the spacing between the limit wheel 74 and the toggle wheel 73 is clearance-matched with the diameter of the wire rope 52, the limit wheel 74 and the toggle wheel 73 provide a stable point to guide the lifting and lowering of the wire rope 52, avoiding the adverse effect of the position change of the wire rope 52 on the drum on the experiment, and the extension and retraction of the electric push-pull rod 71 can change the position of this stable point, change the hammer landing point, and superimpose the use of the linear module above to expand the adjustment range.

[0044] A pair of raised lubricating bars 722 are respectively provided on the inner walls on the upper and lower sides of the limiting groove 721. The raised lubricating bars 722 provide a lubricating surface to reduce the friction between the wire rope 52 and the inner wall of the limiting groove 721, thereby ensuring the smooth movement of the wire rope in the groove. The spacing between a pair of lubricating bars 722 is smaller than the width of the limiting groove 721. Such a design can ensure that when the wire rope moves in the limiting groove, it always contacts at least one lubricating bar, thereby achieving a continuous lubrication effect. The lubricating bar 722 can provide more stable support and reduce the vibration and swing of the wire rope when it moves at high speed or frequently. The lubricating bar can be made of self-lubricating wear-resistant material or lubricant can be applied to the lubricating bar, which simplifies the maintenance process of the equipment. The provision of the lubricating cross bar 722 not only improves the sliding performance of the steel wire rope 52 in the limit groove during the operation of the toggle switch 7, improves the stability and reliability, ensures the precise control of the steel wire rope 52 during the experiment, but also helps to reduce wear and improve the stability and maintainability of the equipment, thereby enhancing the performance and efficiency of the entire building board impact resistance comprehensive detection device.

[0045] A rotating support 751 is provided at the left end of the limit slot 721, and a toggle rod 75 is vertically fixedly installed on the rotating support 751. The rotating support 751 provides a stable support point and rotation center for the toggle rod 75. A plurality of spaced toggle wheels 73 are rotatably installed on the toggle rod 75. These toggle wheels 73 are in contact with the steel wire rope 52, increasing the points at which the toggle steel wire rope is toggled, making it easier to swing, thereby realizing the striking action of the hammer 6. A reset spring 752 is provided between the toggle rod 75 and the limit frame 72. The function of the reset spring is to restore the toggle rod to its initial position after the toggle wheel completes the toggle action, in preparation for the next toggle. Figure 2 As shown, when the toggle 7 is working, the toggle rod 75 rotates and aligns with the shape of the wire rope 52 under the action of the return spring 752, and guides the wire rope through the rotation of the toggle wheel 73, so that it drives the hammer 6 to strike. Figure 1 As shown in the figure, after the toggle is completed, the reset spring returns the toggle rod to its original position. This design can adapt to the toggle requirements of different forces and frequencies, and provides a flexible impact method for the comprehensive impact resistance detection device of building panels.

[0046] Embodiment 3: As attached Figure 5As shown, the difference from other embodiments is that the clamp 4 includes two pairs of side plates 41 arranged at intervals, which constitute the main structure of the clamp and are used to support and position the building board. A positioning groove 42 is provided on the side plate 41, and two clamping rods 43 are provided in the positioning groove 42. A fastening screw 44 is threadedly connected to one end of the positioning groove 42, and a pressure plate is provided at the inner end of the fastening screw 44. The pressure plate is used to press the outer clamping rod 43 so that the building board is clamped between the two clamping rods 43. When the screw rotates, the pressure plate will move along the screw, thereby pushing the clamping rod 43 to approach or separate the center line. A handle is provided at the outer end of the fastening screw 44, and the operator can control the rotation of the fastening screw by rotating the handle to achieve rapid clamping or release of the building board. The clamping rod 43 is used to directly contact the building board to achieve the fixation of the board.

[0047] When in use, the operator rotates the handle to drive the tightening screw 44 to move the pressure plate, thereby pressing the outer clamping rod 43. The distance between the clamping rods 43 is reduced, and the building board is clamped and fixed. This clamp design provides a simple and reliable board fixing method, which is suitable for building boards of various sizes and shapes, is easy to operate, and can ensure the stability and safety of the board in the impact resistance test.

[0048] A supporting fork 21 is slidably mounted on the flip frame 2. The supporting fork 21 is used to support the bottom of the plate to ensure the stability of the plate during the flipping process. A jack 22 is provided at the bottom of the supporting fork 21. The jack 22 is a commonly used lifting equipment, which is used to adjust the height of the supporting fork when necessary to adapt to plates of different sizes, and also facilitate workers to carry plates for loading and unloading. A supporting pad 23 is provided at the lower end of the jack 22. When the jack is raised, the supporting pad is in contact with the ground to provide a stable support point. A fixing rod 24 is provided between the supporting pad 23 and the flip frame 2. The fixing rod 24 is used to connect the supporting pad and the flip frame to ensure the stability of the entire supporting structure. During use, the height of the supporting fork can be adjusted by operating the jack 22 to adapt to plates of different sizes. It is suitable for testing occasions where the height of the plate needs to be adjusted.

[0049] Embodiment 4: As attached Figure 6 As shown, the only difference from other embodiments is that the angle adjuster 3 includes a rotating shaft 31, a gear 32, a rack 33 and a lifting driver. The rotating shaft 31 is rotatably connected to the support frame 1. The gear 32 and the flip frame 2 are fixedly installed on the rotating shaft 31. The lifting driver is fixedly installed on the support frame 1. The lifting driver includes two lifting cylinders 34. A rack 33 is fixedly installed between the output ends of the two lifting cylinders 34. The rack 33 is meshed with the gear 32. The operator controls the extension and retraction of the lifting cylinder 34 to move the rack 33 along the support frame 1, thereby driving the gear 32 meshed with the rack to rotate. The rotation of the gear 32 drives the rotating shaft 31 and the connected flip frame 2 to rotate around the rotating shaft to adjust the angle of the plate.

[0050] Embodiment 5: As attached Figure 6 As shown, the difference from other embodiments is that the flip frame 2 is provided with a plurality of first ultrasonic transceivers 25, and the hammer 6 is provided with a plurality of second ultrasonic transceivers 61. The second ultrasonic transceivers 61 are required to receive ultrasonic signals from the side or the bottom. One solution is to set two second ultrasonic transceivers 61 to receive ultrasonic signals from the side and the bottom respectively. This implementation scheme has a simple structure and low use cost, but the angle and direction that can be detected are small. Another solution is to add an automatic pan-tilt platform to the second ultrasonic transceiver 61. The automatic pan-tilt platform can rotate the direction of the second ultrasonic transceiver 61 according to the angle of the angle adjuster so that it faces the first ultrasonic transceiver 25 and the surface of the plate. This implementation scheme has a large detection angle range and strong adaptability, but it has a complex structure and a high use cost.

[0051] The first ultrasonic transceiver 25 and the second ultrasonic transceiver 61 are connected in ultrasonic communication and are responsible for receiving ultrasonic signals reflected or transmitted from the board. The first ultrasonic transceiver 25 and the second ultrasonic transceiver 61 are arranged on both sides of the building board to detect its material defects through ultrasonic transmission. If the signal encounters defects inside the board, such as cracks, gaps or other discontinuities, the propagation characteristics of the signal will change, and these changes can be detected by the transceiver. During the impact process, the second ultrasonic transceiver 61 can detect the distance between the hammer and the board by receiving the reflected or transmitted ultrasonic signal, monitor the speed change, and provide more accurate impact force data. After the impact is completed, the first ultrasonic transceiver 25 emits an ultrasonic signal, which passes through the board and is received by the second ultrasonic transceiver 61. If there are defects inside the board, the signal strength, time delay or other parameters will be affected, thereby providing information about the nature and location of the defect. It saves the trouble of removing the board or hammering for visual inspection. This design allows a comprehensive internal inspection of the building board without destroying the board, improving the efficiency and accuracy of the inspection.

[0052] In order to improve the accuracy of the impact test results, a roller chain for stabilization and guidance is tied and fixed to the steel wire rope 52. The roller chain and the steel wire rope work closely together to bear the load together. The two can be fixed by cable ties or other means to achieve matching use. The upper end of the roller chain is fixedly wound on the reel 51, and the lower end of the roller chain is hinged to the hammer 6. The use of the roller chain increases the overall stability of the swing of the steel wire rope, avoids lateral deviation during movement, helps to more accurately control the direction of the steel wire rope, and ensures that the hammer 6 moves along the predetermined trajectory. The use of roller chains improves the reliability and safety of the system and reduces errors caused by the swing or vibration of the steel wire rope. This design is suitable for impact resistance tests of building panels that require precise control of the impact force and direction.

[0053] Example 6: For general building board impact test with sandbags, in the preparation stage, sandbags of certain specifications need to be prepared, sand is put into the sandbags, and the required weight is weighed on a scale, for example, 60 kg. Then the bag mouth is tied tightly with a rope to ensure that it will not fall apart during the impact of the sandbag. Testing different boards requires changing the weight of the sandbag, which is troublesome to operate manually.

[0054] As attached Figure 8 As shown, in order to facilitate the automatic weight adjustment, the structure of the hammer is designed as follows: the hammer includes a sandbag 62, a tension rope 63 and a pressure cover 64. The sandbag 62 is the main component in the impact test, which is used to contain yellow sand and form an impact force. The pressure cover 64 is installed in the bag mouth of the sandbag to close the bag mouth and compact the sand. A tension spring 641 is fixedly connected between the pressure cover 64 and the wire rope. When the sandbag is placed for weighing, the tension rope 63 first becomes a relaxed state, and then the wire rope and the tension spring 641 are in a relatively tight state. The tension spring 641 can pull up the pressure cover 64 through elastic force when the wire rope is placed on the sandbag, making room for the added sand.

[0055] The pressure cap 64 is provided with a sand inlet check valve 642, which allows sand to enter the sandbag but prevents it from flowing out in the opposite direction, so as to facilitate the filling of the sandbag. A rope hole 621 is provided on the side wall of the bag mouth of the sandbag, and a tension rope 63 is passed through the rope hole 621. A rope buckle 622 is provided on the inner wall of the bottom of the sandbag, and the rope buckle 622 can also be replaced with a pulley. The upper end of the tension rope 63 is fixedly connected to the steel wire rope, and the lower end of the tension rope 63 is fixedly connected to the pressure cap 64 after passing through the rope buckle 622. When the steel wire rope is lifted, the bag mouth can be tightened, and the pressure cap 64 is driven to press the sand downward, so that the sand is compacted and not easy to disperse. Finally, the sandbag is lifted, and an automatic discharge valve 623 is provided on the bottom side wall of the sandbag. The automatic discharge valve 623 can automatically open to discharge the sand in the sandbag, thereby reducing the weight of the sandbag. The automatic discharge valve 623 uses an electric plug valve with wireless control function, which is not easy to clog and get stuck, and is convenient for automatic control of opening and closing, allowing the weight of the sandbag to be automatically adjusted when needed, simplifying the adjustment process of the sandbag weight.

[0056] The support frame is provided with a weight adjustment device 9, which is arranged in the middle position of the support frame, at the rear position below the electric hoist lift 5 and above the flip frame 2, so as to facilitate control and adjustment. The weight adjustment device 9 includes a sand storage box 91, a sand adding device 92, a weighing device 93 and an adjustment controller. The sand storage box 91 is used to collect the sand discharged from the automatic discharge valve 623, and the sand can be reused, thereby improving the recycling rate of the test material. The sand adding device 92 is used to add sand to the bag mouth of the sandbag to increase the weight of the hammer and ensure that the impact force meets the test requirements. The weighing device 93 is used to weigh the weight of the hammer (including the sandbag 62 and the sand in the sandbag) to ensure the accuracy of the test weight. The automatic discharge valve 623, the sand adding device 92, and the weighing device 93 are all connected to the adjustment controller for communication to realize automatic control and data feedback.

[0057] Through the weight adjustment device 9, the weight of the sandbag can be automatically adjusted, reducing the trouble of manual operation and improving the automation, efficiency, accuracy and safety of the sandbag impact test for building panels. When in use, the sandbag is placed on the weighing device 93 for weighing. When the weight is insufficient, the sand adding device 92 pours sand into the bag mouth, and the sand is filled into the sandbag 62 through the sand inlet one-way valve 642 to reach the required weight. When the steel wire rope lifts the sandbag, the tightening rope 63 drives the pressure cover 64 to press down, ensuring the sealing of the sandbag and the compactness of the sand, and ensuring that the sandbag will not fall apart during the impact. When the weight is too high, the weight of the sandbag can be automatically adjusted as needed through the automatic unloading valve 623 without manual intervention.

[0058] In order to reduce the friction between the sand and the rope, the gland 64 is provided with a rope hole 643, a first corrugated tube 631 is provided between the rope hole 643 and the rope hole 621, and a second corrugated tube 632 is provided between the rope hole 643 and the rope buckle 622. The tension rope 63 is routed in the first corrugated tube 631 and the second corrugated tube 632. The design of the first corrugated tube and the second corrugated tube increases the protection of the tension rope, reduces the direct contact between the sand and the rope, and reduces the friction. The tension rope is protected from wear, the risk of rope breakage is reduced, and the service life of the tension rope is increased.

[0059] The sand adding device 92 is a vertical tube screw conveyor, which uses a screw conveyor to lift and convey sand. The upper and lower ends of the screw conveyor are respectively provided with a sand inlet 921 and a sand outlet 922, and the sand inlet 921 is connected to the bottom of the sand storage box 91, and is used to receive sand from the sand storage box 91. Sand is transported to the sandbag 62 through the sand outlet 922. An automatic telescopic feeding pipe 923 is provided on the sand outlet 922. The feeding pipe can automatically extend and retract as needed to accurately feed sand into the bag mouth of the sandbag 62. When the weight of the sandbag needs to be increased, the adjustment controller starts the sand adding device 92, and the screw conveyor starts working, and the sand in the sand storage box 91 is transported to the inside of the screw conveyor through the sand inlet 921. The spiral blade shaft in the screw conveyor transports the sand upward, and finally the sand is fed into the automatic telescopic feeding pipe 923 through the sand outlet 922. The automatic telescopic feeding tube 923 automatically adjusts its length according to the position of the sandbag 62 and the amount of sand to be added, and accurately feeds the sand into the bag opening of the sandbag 62 to achieve the sand adding operation. The design of the sand adding device 92 realizes the automatic adjustment of the weight of the sandbag through the vertical tubular screw conveyor and the automatic telescopic feeding tube 923, improves the automation and efficiency of the sandbag impact test for building panels, and ensures the accuracy and reliability of the test.

[0060] The weighing device 93 includes a positioning tray 931, a lever 932, a weighing sensor 933 and a display 934. The positioning tray 931 is arranged on the opening of the sand storage box 91, and is used to support the sandbag 62 and weigh it. The positioning tray 931 is evenly distributed with sand leakage holes 935, which allow sand to flow freely and reduce the error during weighing. The positioning tray 931 is fixedly connected to the lever 932, and the lever 932 is hinged with the inner wall of the sand storage box 91 to form a fulcrum, so that the lever can move up and down around the fulcrum. A weighing sensor 933 is arranged between the lower side of the lever 932 and the sand storage box 91, and the lever 932 is used to transfer the weight of the sandbag to the weighing sensor 933. The output of the weighing sensor is proportional to the weight of the sandbag, and the weight is converted into an electrical signal. The weighing sensor 933 is electrically connected to the adjustment controller and the display 934, and the weighing sensor 933 transmits the measured weight data to the adjustment controller for processing. The display 934 is fixedly mounted on the outer wall of the sand storage box 91, and the display is used to display the weight measured by the weighing sensor 933, so that the operator can read it easily.

[0061] When the sandbag 62 is placed on the positioning tray 931, the weight of the sandbag is transmitted to the weighing sensor 933 through the lever 932. The weighing sensor 933 measures the weight of the sandbag and transmits the weight data to the adjustment controller. The adjustment controller controls the sand adding device 92 to add sand to the sandbag or controls the automatic discharge valve 623 to discharge sand according to the data of the weighing sensor 933 and the preset target weight to adjust the weight of the sandbag. The display 934 displays the weight of the sandbag in real time to ensure that the operator can monitor the weight adjustment process.
