Description

Technical Field

[0001] The invention relates to the technical field of template strength detection, in particular to a magnesium alloy building template strength testing device. Background Art

[0002] Building formwork is a temporary supporting structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric dimensions and maintain their correct position. In order to improve the practicality of building formwork, magnesium alloy will be used to make building formwork. Before using magnesium alloy formwork, the formwork sample needs to be tested for strength to detect whether the building formwork meets the standards.

[0003] At present, when conducting strength testing on magnesium alloy building formwork, it is necessary to test the maximum strength of the formwork sample, that is, to measure the maximum bearing capacity of various properties of the formwork sample by applying mechanical stress. At this time, structural damage such as fracture will occur, resulting in debris splashing. For this problem, most traditional solutions only use ordinary hard plates for shielding, so as to provide shielding and splash-proof measures for the strength testing process of alloy materials, so as to avoid metal debris splashing and harming the testers. However, although the existence of alloy debris will not harm the testers, during the testing and loading process of the alloy formwork, the formwork sample is easily contaminated, affecting the accuracy of the test. At this time, the testers are usually required to wear protective equipment on their hands, and after each pair of formwork samples are tested, they hold a small cleaning workpiece for processing. It is cumbersome to process each test. If batch processing is performed according to the formwork model in the strength test, metal debris is easily contaminated during loading, and there is a hidden danger of affecting the accuracy of the test. It can be seen that the existing test device needs to improve the efficiency of continuous testing of formwork samples on the premise of ensuring the accuracy of the test, and needs to be improved in simplifying the operation process required by the testers.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention utilizes a testing machine body to test the strength of the template, and uses a pressure sensor to record the maximum pressure strength that the template sample can bear under the test state. Through the combined use of shielding components, auxiliary components and matching components, when the template sample reaches the maximum strength pressure and produces structural damage under the test limit state, protective treatment is performed to avoid the damaged template debris from splashing inside the testing machine body, thereby avoiding affecting the space required for the template sample test during the next test, and avoiding affecting the numerical accuracy of the next test, thereby improving the efficiency and practical performance of template continuity detection.

[0025] Second, the present invention enables the shielding plate to be vertically displaced by the coordination of the displacement plate, the rod member 1 and the fixed axis, and at the end of the displacement path, the collection frame will be deflected, so that the metal debris generated during the template strength test can be well processed, and the debris can be collected in time. When multiple metal templates are continuously tested for strength, the metal template will not be contaminated by the debris generated by one during loading, which will affect the accuracy of the strength test;

[0026] At the same time, by adopting this method, after completing the strength test of each template, the inspectors can collect the debris more conveniently. The labor intensity of the inspectors is low, the workload is greatly reduced, and it can also further provide services for the accuracy of template strength testing from the perspective of avoiding personnel fatigue.

[0027] 2. The present invention cooperates with structures such as gears, parallel plates and slide grooves to enable the brush plate to vertically displace before the baffle plate and deflect at the end of the displacement path. The brush plate can be moved downward to brush off the debris on the baffle plate due to splashing, so that the debris generated in the detection process can be collected more comprehensively. At the same time, the deflection of the end of the brush plate path can have a throwing-out process, so that the baffle plate can be processed more thoroughly, and the situation of incomplete processing at one time and the debris on the baffle plate falling again after the collection frame is deflected will not occur, thereby preventing the next template sample from being contaminated by debris during the loading process, affecting the accuracy of the corresponding project detection.

[0028] 3. The present invention uses the coordination of structures such as the gear rod, the pulley assembly and the matching shaft to make the brush plate vibrate when it moves downward, but not vibrate when it moves upward. In this way, when the brush plate moves downward, it can ensure that the metal debris contaminated on the brush is shaken off into the collection frame, and when the device moves upward for use, it does not vibrate, thereby preventing the metal debris that may exist on it from falling into the detection area of ​​the test machine body when there is no collection frame below, thereby further assisting the cleanliness of the detection area of ​​the test machine body and ensuring the accuracy of the metal template continuity detection;

[0029] At the same time, since the brush shaft will move before the shielding shaft, the shielding plate can be scraped off first, and then the shielding plate is moved vertically downward. The two are carried out one after another, thereby further avoiding the scattering of debris and avoiding affecting the cleanliness of the detection area of ​​the testing machine body.

[0030] Fourth, the present invention makes the collection frame vibrate when it is deflected through the coordination of structures such as the lifting shaft, the cylinder and the lifting gear, so that the metal debris caused by the detection can be located in the bottom area after the collection frame is deflected. There is no need for the detection personnel to scrape the inner wall, and the bottom area can be directly shoveled, which makes it convenient for the detection personnel to collect the debris, and further provides services for the accuracy of the template strength detection from the perspective of avoiding personnel fatigue.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] For example, see Figures 1 to 11 The present invention provides a magnesium alloy building formwork strength testing device, comprising a testing machine body 1, wherein two shells 2 are fixedly connected to the surface of the testing machine body 1, opening one and opening two are respectively provided on opposite sides of the two shells 2, inner walls of the two openings one are slidably connected with a shielding shaft 3, inner walls of the two openings two are slidably connected with a brush shaft 4, the shaft arm of the shielding shaft 3 is rotatably connected with a shielding plate 5, the shaft arm of the shielding shaft 3 is fixedly connected with a collecting frame 6, the shielding plate 5 is slidably connected to the surfaces of the two shells 2, the shaft arm of the brush shaft 4 is fixedly connected with a brush plate 7, and processing components are arranged in the two shells 2.

[0045] The processing component includes a shielding component, an auxiliary component, a matching component, a lifting component and a driving component. The shielding component is arranged in the shell 2, the auxiliary component is transmission-connected to the shielding component, the matching component is transmission-connected to the auxiliary component, and the lifting component is transmission-connected to the shielding component.

[0046] See also Figures 1 to 4The driving component includes a driving box 36, which is fixedly connected to the surface of the shell 2. The inner wall of the driving box 36 is rotatably connected with a threaded rod 37, and the rod arm of the threaded rod 37 is threadedly connected with a threaded block 38. The threaded block 38 is slidably connected to the inner wall of the driving box 36. An opening three is provided on the surface of the shell 2, and the brush shaft 4 passes through the opening three. The end of the brush shaft 4 is rotatably connected to the surface of the threaded block 38. The threaded rod 37 can be rotated to displace the threaded block 38 along the rod arm of the threaded rod 37, so that the brush shaft 4 can move vertically downward.

[0047] See also Figure 4 A motor 39 is fixedly connected to the inner wall of the driving box 36, and the output end of the motor 39 is fixedly connected to the end of the threaded rod 37. By starting the motor 39, the threaded rod 37 can be easily driven to rotate.

[0048] In this embodiment, when it is necessary to perform a strength test on the building template sample, the template sample can be placed in the testing machine body 1. The testing machine body 1 is provided with a hydraulic component, a fixed limit component and a data processing component. The hydraulic component includes a hydraulic drive device, and the data processing component includes a pressure sensor. The pressure sensor is embedded in the hydraulic head of the hydraulic drive device. The fixed limit component is composed of a bolt clamp. The template sample is fixedly limited by the bolt clamp to keep it in the position of the required detection state. Then the hydraulic drive device is driven to continuously apply pressure to the template sample and slowly increase the pressure index. The pressure sensor records the applied pressure value in real time. When the maximum pressure intensity that the template sample can withstand is reached, the pressure sensor locks the pressure intensity value currently applied. This pressure index is the maximum strength pressure that the current template sample can bear in the current state. In this way, the strength test using the testing machine body 1 can be completed. After the test is completed, the template residue remaining on the bolt clamp can be removed. When the template sample reaches the maximum strength pressure, structural damage will occur. Therefore, before the test, the processing component can be started. First, The shielding plate 5 is moved up to shield the detection area, and then the strength test of the alloy template is completed until the template sample reaches the maximum strength and breaks. After obtaining the required data, the shielding plate 5 is lowered and the template sample is taken out. During the strength test, the debris splashing when the maximum strength is reached will be blocked by the shielding plate 5 and will not hurt the test personnel. After the test is completed, the test personnel can start the processing component to make the shielding component operate first. Through the operation of the shielding component, the shielding plate 5 is moved vertically downward, and the collection frame 6 is collected at the end of the displacement path. Deflection allows the shielding plate 5 to block the detection area when it moves up and not to block the detection area when it moves down. When moving up, the collection frame 6 below is biased to the side of the working area of ​​the shielding plate 5 to collect the falling splashing metal. When moving down, the collection frame 6 is biased to the other side of the shielding plate for personnel to handle. In this way, the detection process can handle the metal debris in the process well, and the debris can be collected in time. When multiple metal templates are continuously subjected to strength testing, the metal templates will not be contaminated by the debris generated by one during loading, thereby affecting the accuracy of the strength test.

[0049] During the operation of the above-mentioned shielding components, the auxiliary components will be driven to operate first, so that the brush plate 7 will be displaced before the shielding plate 5, and will be deflected at the end of the displacement path, so that the debris on the shielding plate 5 due to splashing will be brushed off through the prior displacement of the brush plate 7, and the end of the downward movement path of the brush plate 7 will be deflected, so that there is a throwing process, and the shielding plate 5 is efficiently self-cleaned, which can make the shielding plate 5 more thoroughly processed, and there will be no situation where the processing is not in place at one time. After the collection frame 6 is deflected, the debris on the shielding plate 5 will fall again, affecting the accuracy of the next template strength test.

[0050] When the brush plate 7 moves vertically downward, vibration will also be generated. This vibration can ensure that the metal debris contaminated on the brush plate 7 is shaken off into the collection frame 6 when the brush plate 7 moves downward. When the device moves upward and is ready for use, no shaking will be generated. This can prevent possible metal debris on it from falling into the detection area when there is no collection frame 6 below, thereby affecting the accuracy of the template strength detection.

[0051] It is worth noting that during the operation of the shielding component, the lifting component will also be driven to operate, so that the collection frame 6 will also vibrate when it is deflected. This vibration can make the collection frame 6 deflect with the metal fragments inside, and the materials on its inner wall can all fall to the bottom of the collection frame 6, making it more convenient for the inspection personnel to collect later without the need to scrape the inner wall, further reducing the labor intensity required for the inspection personnel in the strength test of the template.

[0052] See also Figures 1 to 9 The shielding component includes a displacement plate 8, the inner wall of the displacement plate 8 is slidably connected to two limit rods 9, the ends of the two limit rods 9 are fixedly connected to the inner wall of the shell 2, and the rod arms of the two limit rods 9 are sleeved with return springs 10. The shielding shaft 3 is rotatably connected to the inner wall of the displacement plate 8, and the shaft arm of the shielding shaft 3 is fixedly connected to a rotating rod 11. The inner wall of the rotating rod 11 is hinged with a rod member 12. The inner wall of the displacement plate 8 is rotatably connected to a fixed shaft 13, and the shaft arm of the fixed shaft 13 is fixedly connected to a sliding sleeve 14. The rod member 12 is slidably connected to the inner wall of the sliding sleeve 14, and the rod arm of the rod member 12 is sleeved with a shielding spring 15. The two ends of the shielding spring 15 are respectively fixedly connected to the surface of the sliding sleeve 14 and the rod arm of the rod member 12. The surface of the displacement plate 8 is fixedly connected to a plate member 16, and the inner wall of the shell 2 is fixedly connected to a shaft body 17 and a shaft body 2 18.

[0053] In this embodiment, the displacement plate 8 can be moved so that the displacement plate 8 slides along the lever arms of the two limit rods 9, so that the return spring 10 is compressed, and at this time, the shielding shaft 3 is synchronously driven to move vertically downward, so that the shielding plate 5 moves vertically downward. In the process of the shielding shaft 3 moving downward, the rotating rod 11 and the structure connected thereto are synchronously driven to move downward. When the moving rotating rod 11 contacts the lower shaft body 18, as the rotating rod 11 continues to move downward, the shaft body 18 pushes the rotating rod 11 so that the rotating rod 11 deflects around the shielding shaft 3 as the axis, and at this time, the pushing rod 12 slides along the inner wall of the sliding sleeve 14. The shielding spring 15 is stretched until one end of the rotating rod 11 is separated from one side of the plate 16 and the other end of the rotating rod 11 contacts the other side of the plate 16, thereby completing the deflection of the shielding axis 3. That is, in this process, the shielding spring 15 is actively compressed once, so that the connection point between the rod 12 and the rotating rod 11 is changed from one side of the shielding axis 3 to the other side. In this way, the shielding axis 3 can be deflected through the deflection of the rod 12 at this stage, thereby making the collecting frame 6 deflected at this stage, and its opening area is changed from the working area of ​​the template sample strength detection to the non-working area on the other side of the shielding plate 5.

[0054] When the displacement plate 8 moves upward, the cooperation principle between the rotating rod 11 and the upper shaft body 17 is consistent with the cooperation principle between the rotating rod 11 and the shaft body 2 18, so the reverse deflection of the rotating rod 11 can be completed, so that the shielding plate 5 can be used for shielding when it moves upward and does not block the detection area when it moves downward. When the shielding plate 5 moves upward, the collection frame 6 below is biased toward the working area to collect the falling splashing metal blocked by the shielding plate 5. When it moves downward, the collection frame 6 is biased toward the side of the personnel for processing by the personnel.

[0055] By adopting the above method, the metal debris generated during the template strength test can be well processed and the debris can be collected in time. When multiple metal templates are continuously subjected to strength tests, the metal templates will not be contaminated by the debris generated during loading, thereby affecting the accuracy of the strength test.

[0056] At the same time, by adopting this method, after completing the strength test of each template, the inspectors can collect the debris more conveniently. The labor intensity of the inspectors is low, the workload is greatly reduced, and it can also further provide services for the accuracy of template strength testing from the perspective of avoiding personnel fatigue.

[0057] See also Figures 1 to 9 The auxiliary components include a gear 19, which is fixedly connected to the shaft arm of the brush shaft 4. A slide groove 20 for displacement of the brush shaft 4 is provided on the surface of the displacement plate 8. Two slide seats 21 are fixedly connected to the surface of the displacement plate 8. A rack row 22 and a parallel plate 23 are fixedly connected to the surfaces of the two slide seats 21, respectively.

[0058] In this embodiment, the brush shaft 4 can be moved downward so that the brush shaft 4 is displaced before the shielding shaft 3. During this displacement process, the brush shaft 4 will slide along the slide groove 20 on the displacement plate 8, and during its sliding process, the gear 19 is synchronously driven to displace. On the initial path, the teeth of the gear 19 are in contact with the side of the parallel plate 23, so that the gear 19 cannot rotate during this process, that is, the brush plate 7 moves downward while keeping the brush in contact with the shielding plate 5, and the metal debris contaminated on the shielding plate 5 is removed. Scrape off, and when the gear 19 is out of contact with the parallel plate 23, it is meshed with the teeth of the rack row 22. At this time, as the gear 19 moves downward, it will rotate, so that the brush plate 7 is deflected. After the brush shaft 4 is displaced, it contacts the groove wall of the slide groove 20. At this time, the brush shaft 4 is continued to be driven downward, and the slide groove 20 can be used to push the displacement plate 8 to move downward. In this way, the brush plate 7 can be vertically displaced before the baffle plate 5, and the deflection is performed at the end of the displacement path.

[0059] Through the above-mentioned method, the debris on the shielding plate 5 due to splashing can be brushed off by moving the brush plate 7 downward, so that the debris generated in the detection process can be collected more comprehensively. At the same time, the deflection of the brush plate 7 at the end of the path can have a throwing-out process, so that the shielding plate 5 can be processed more thoroughly, and there will be no situation where the debris on the shielding plate 5 falls again after the collection frame 6 is deflected due to incomplete processing at one time, thereby preventing the next template sample from being contaminated by debris during the loading process, affecting the accuracy of the corresponding project detection.

[0060] Embodiment 2, based on the above embodiment:

[0061] See also Figures 1 to 9 The mating components include two mating seats 24, both of which are fixedly connected to the inner wall of the outer shell 2, and the inner walls of the two mating seats 24 are slidably connected with a gear rod 25. The gear rod 25 and the opposite side of the outer shell 2 are fixedly connected with two mating springs 26. The surface of the displacement plate 8 is rotatably connected with a mating shaft 27, and the mating shaft 27 is connected to the shielding shaft 3 through a pulley assembly 28. The shaft arm of the mating shaft 27 is fixedly connected with a pull rope 29, and the end of the pull rope 29 is fixedly connected with a slider 40, and the slider 40 is slidably connected to the surface of the gear rod 25.

[0062] In this embodiment, during the vertical downward movement of the brush shaft 4 relative to the housing 2, the brush shaft 4 will contact the gear rod 25 on its displacement path, so that the gear rod 25 will continuously compress the matching spring 26, thereby causing the brush shaft 4 to vibrate during the displacement process, that is, causing the brush plate 7 to vibrate during the displacement. When the device is reset to prepare for template detection, the rotating rod 11 has completed the deflection. When it deflects, it will be transmitted by the pulley assembly 28, causing the matching shaft 27 to deflect synchronously. The deflection of the matching shaft 27 can pull the pull rope 29, so that the slider 40 pulls the gear rod 25 to actively compress the matching spring 26, that is, causing the gear rod 25 to disengage from the displacement path of the brush shaft 4. In this way, it can be achieved that when the brush plate 7 moves downward, it will vibrate, and when it moves upward, it will not vibrate.

[0063] In this way, when the brush plate 7 moves downward, it can be ensured that the metal debris contaminated on the brush is shaken off into the collection frame, and when the device moves upward for use, no vibration is generated, thereby preventing possible metal debris on it from falling into the detection area of ​​the test machine body 1 when there is no collection frame 6 below, thereby further assisting the cleanliness of the detection area of ​​the test machine body 1 and ensuring the accuracy of the metal template continuity detection.

[0064] At the same time, through the above process, the brush shaft 4 is displaced before the shielding shaft 3, so that the shielding plate 5 can be scraped first, and the shielding plate 5 is moved vertically downward. The two are carried out successively, which further avoids the possibility of debris flying and affecting the cleanliness of the detection area of ​​the testing machine body 1.

[0065] Embodiment 3, based on the above embodiment:

[0066] See also Figures 2 to 11 The lifting component includes an arc-shaped rack 30, which is fixedly connected to the inner wall of the collecting frame 6. The inner wall of the baffle plate 5 is rotatably connected with a lifting shaft 31. The shaft arm of the lifting shaft 31 is fixedly connected with a lifting gear 32. The teeth of the lifting gear 32 are meshed with the teeth of the arc-shaped rack 30. The shaft arm of the lifting shaft 31 is fixedly connected with a cylinder 33. The side wall of the cylinder 33 is provided with a continuous groove. The groove wall of the continuous groove is slidably connected with a transmission rod group 34. The rod arm of the transmission rod group 34 is slidably connected with the inner wall of the baffle plate 5. The end of the transmission rod group 34 is fixedly connected with a knocking head 35.

[0067] In this embodiment, during the deflection of the above-mentioned collecting frame 6, the arc-shaped rack 30 will be synchronously driven to deflect, so that the lifting gear 32 will rotate, and then the lifting shaft 31 will rotate, so that the cylinder 33 will rotate, that is, the continuous groove will move in a circular motion, so that the transmission rod group 34 will move axially back and forth, and then the knocking head 35 will move axially back and forth, thereby knocking the inner wall of the collecting frame 6, so that the collecting frame 6 will vibrate when deflected.

[0068] Through the vibration generated by the collection frame 6 during deflection, the metal debris caused by the detection can be located in the bottom area after the collection frame 6 is deflected. There is no need for the detection personnel to scrape the inner wall, and the bottom area can be directly shoveled, which makes it convenient for the detection personnel to collect the debris, and further provides services for the accuracy of template strength detection from the perspective of avoiding personnel fatigue.

[0069] Also, see Figure 5 The size of the baffle plate 5 is adapted to the size of the testing machine body 1, and the sizes of the rack row 22 and the parallel plate 23 are adapted to the size of the gear 19. By limiting the sizes of the rack row 22, the parallel plate 23 and the gear 19, the gear 19 can smoothly cooperate with the rack row 22 and the parallel plate 23 when moving downward.

[0070] Working principle: When the magnesium alloy building template strength testing device is used, when it is necessary to perform a strength test on the building template sample, the template sample is placed in the testing machine body 1, and the testing machine body 1 is used to perform strength testing. Before the test, the driving motor 39 is reversed to move the shielding plate 5 upward to shield the test area, and then the strength test is performed through the testing machine body 1 until the template sample reaches the maximum strength and breaks, and the strength test of the alloy template is completed. After obtaining the required data, the driving motor 39 rotates forward, and the brush plate 7 is displaced before the shielding plate 5, and deflected at the end of the displacement path, so that the debris on the shielding plate 5 due to splashing is brushed off by the advance displacement of the brush plate 7, and the end of the downward movement path of the brush plate 7 is deflected, so that there is a throwing process, and the shielding plate 5 is efficiently self-cleaned, so that the shielding plate 5 can be processed more thoroughly, and there will be no inadequate processing at one time. After the collection frame 6 is deflected, the debris on the shielding plate 5 falls again, affecting the accuracy of the next template strength test;

[0071] As the brush plate 7 moves downward, the shielding plate 5 is then driven to move vertically downward, and the collecting frame 6 is deflected at the end of the displacement path, so that the shielding plate 5 blocks the detection area when it moves upward, and does not block the detection area when it moves downward. When it moves upward, the collecting frame 6 below is biased to one side of the working area of ​​the shielding plate 5 to collect the falling splashed metal. When it moves downward, the collecting frame 6 is biased to the other side of the shielding plate for personnel to handle. In this way, the detection process can well handle the metal debris in the process, and the debris can be collected in time. When multiple metal templates are continuously tested for strength, the metal templates will not be contaminated by the debris generated by one when loading, affecting the accuracy of the strength test;

[0072] When the brush plate 7 moves vertically downward, vibration will also be generated. This vibration can ensure that the metal debris contaminated on the brush plate 7 is shaken off into the collection frame 6 when the brush plate 7 moves downward. When the device moves up and is ready for use, no shaking will be generated, which can prevent the metal debris that may exist on it from falling into the detection area when there is no collection frame 6 below, affecting the accuracy of the template strength test. When the collection frame 6 deflects, vibration will also be generated. This vibration can make the collection frame 6 deflect with the metal fragments inside, and the materials on its inner wall can all fall to the bottom of the collection frame 6, making it more convenient for the inspector to collect later, without the need to scrape the inner wall, further reducing the labor intensity required for the inspector to perform strength testing on the template.
