[0002] The existing Chinese patent: a steel structure net rack deflection detection device (CN204944418U) is very simple to install, the measurement process is intuitive, and only one person can realize the measurement process, the measurement is convenient, and the device has low cost and is convenient for instant production and use on the construction site;

[0003] However, the number and weight of the counterweight blocks cannot be adjusted, so only single weight detection can be performed, and the strength of the steel structure net rack cannot be objectively reflected. If the counterweight blocks are replaced by manual detection, the disassembly, installation and transfer of the counterweight blocks all require a lot of time and are inefficient.

[0004] At the same time, when measuring the sagging distance of the counterweight block by using the scale ruler, manual recording of two values and difference calculation are always required, which is low in convenience. SUMMARY

[0017] Beneficial effects: The present invention adopts the above technical solution, and through the cooperation of the first telescopic cylinder and the motor, the number of the first counterweight blocks hanging on the circular plate is automatically controlled, which can realize the continuous strength test of the steel structure grid frame with different weights, making the test results more accurate, and eliminating the need for manual replacement of the first counterweight blocks, making the test more convenient and improving the test efficiency.

[0018] During measurement, the second counterweight and the limiting block work together to ensure that the first connecting block can always automatically reset to the zero mark position of the measuring block during continuous testing of the steel structure space frame. This allows the operator to obtain the downward bending value of the steel structure space frame continuously by reading only one value each time, without having to read two values ​​and calculate the difference each time, which improves convenience.

[0019] When suspended, the steel pipe is clamped by the locking block to prevent the hook from slipping after the steel pipe bends during the test, which would affect the results. At the same time, the anti-slip component increases the friction with the steel pipe, which helps to improve the clamping stability. Meanwhile, the locking block moves upward, so that its fourth groove fits into the outside of the fixing block, further improving the clamping stability.

[0020] Before testing, the pusher moves the hook downwards to flatten the paint layer or impurities on the steel pipe, preventing them from affecting the subsequent test results. At the same time, the positioning frame quickly positions and adjusts the initial position of the first counterweight. The structure is simple and does not require complex program control or position sensor monitoring, which helps to reduce costs and improve efficiency. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Implementation Plan 1

[0037] A steel structure space frame strength testing device, such as Figures 1-6 As shown, it includes a first support plate 1 and a support frame 2; the support frame 2 is bolted to the upper front part of the first support plate 1; it also includes a first round rod 201, a second support plate 202, a first telescopic cylinder 203, a third support plate 204, a second round rod 205, a first counterweight 206, a sleeve 207, a slide rod 208, a circular plate 209, a third round rod 2023, a measuring unit, a limiting unit, a driving unit, and a suspension assembly; four first round rods 201 are slidably connected to the middle of the first support plate 1; the lower middle part of the first support plate 1... A first telescopic cylinder 203 is bolted to the second support plate 202, and the telescopic end of the first telescopic cylinder 203 is fixedly connected to the second support plate 202. Two third round rods 2023 are welded to the upper side of the second support plate 202. A third support plate 204 is slidably connected to the third round rods 2023. Two second round rods 205 are welded to the middle of the upper side of the third support plate 204. Ten first counterweights 206 are inserted between the two second round rods 205 and slidably connected, and the ten first counterweights 206 are stacked. A first groove 9 is opened on the front side of the first counterweight 206. 1. A second groove 92 is provided, and the second groove 92 is located above the first groove 91, and the width of the second groove 92 is smaller than the width of the first groove 91; a third groove 93 is provided on the rear side of the first counterweight 206, and the third groove 93 is used to adjust the center of gravity position of the first counterweight 206; a sleeve 207 is fixedly connected to the middle of the upper side of the support frame 2; a sliding rod 208 is slidably connected to the inner side of the sleeve 207, and the sleeve 207 and the sliding rod 208 replace the rope used in the prior art detection to avoid the weight from shaking and affecting the detection results; the lower part of the sliding rod 208... A circular plate 209 is welded to the side, and different numbers of first counterweights 206 are hung on the circular plate 209 to apply different downward pressures to the steel structure space frame, thereby quickly detecting the degree of bending of the steel structure space frame under different stress conditions and improving the diversity of test results; a measuring unit is connected to the circular plate 209; a limit unit is connected to the front side of the first support plate 1; a drive unit is connected to the middle of the second support plate 202, which is used to drive the third support plate 204 to move forward or backward; a suspension assembly is connected to the upper side of the slide rod 208.

[0038] It also includes ball bearings 2010; eight ball bearings 2010 are rotatably connected to the inner side of each first counterweight 206. The ball bearings 2010 reduce the friction between the first counterweight 206 and the second round rod 205, so as to avoid excessive friction affecting the test results; each ball bearing 2010 is in contact with the corresponding second round rod 205.

[0039] It also includes a positioning frame 2011; the positioning frame 2011 is bolted to the slide rod 208, and the shortest distance from the upper side of the circular plate 209 to the lower side of the positioning frame 2011 is equal to the shortest distance from the upper side of the first counterweight block 206 to the top of the first groove 91 thereon; the positioning frame 2011 is used to quickly position the circular plate 209 to the side of the first groove 91.

[0040] The drive unit includes a motor 2020, a spur gear 2021 and a rack 2022; the motor 2020 is bolted to the second support plate 202; the output shaft of the motor 2020 is fixedly connected to the spur gear 2021; the rack 2022 is fixedly connected to the lower side of the third support plate 204; the rack 2022 meshes with the spur gear 2021.

[0041] The steel structure frame to be tested is manually fixed in the factory and placed above this device. The suspension assembly is then fixed to the middle of the steel structure frame. The first telescopic cylinder 203 is activated, causing the second support plate 202 to move upwards. The second support plate 202 then causes the first round rod 201 to move upwards, and the parts on the second support plate 202 move upwards, causing all ten first counterweights 206 to move upwards simultaneously. If five first counterweights 206 are needed, the first telescopic cylinder 203 controls the alignment of the first groove 91 on the fifth first counterweight 206 from bottom to bottom with the round plate 209. The motor 20 is then started. 20. Motor 2020 drives spur gear 2021 to rotate, spur gear 2021 drives rack 2022 to move forward, rack 2022 drives third support plate 204 to slide forward on third round rod 2023, third support plate 204 drives the parts on it to move forward, so that the first groove 91 on the fifth first counterweight 206 fits onto the outside of round plate 209, and slide rod 208 passes through all the second grooves 92 above it. Then first telescopic cylinder 203 drives second support plate 202 to move downward, second support plate 202 drives the parts on it to move downward, so that the five first counterweights 206 located below move downward, while the five first counterweights 206 located above move downward. A counterweight 206 is hung on a circular plate 209. Five first counterweights 206 apply gravity to the circular plate 209. Then, the gravity is applied to the middle of the steel structure frame via a sliding rod 208 and a suspension assembly. Under this force, the middle of the steel structure frame bends downwards, and the suspension assembly, sliding rod 208, and circular plate 209 move downwards along with it. The bending degree and strength of the steel structure frame are reflected by measuring the downward distance of the circular plate 209. In use, the number of first counterweights 206 hanging on the circular plate 209 is automatically controlled by the cooperation of a first telescopic cylinder 203 and a motor 2020, enabling continuous strength testing of the steel structure frame with different weights, resulting in more accurate test results. The accuracy is improved, and the first counterweight 206 does not require manual replacement, making the test more convenient and improving the test efficiency. At the same time, the ball bearing 2010 keeps the moving first counterweight 206 stable, and the frictional resistance between the ball bearing 2010 and the first counterweight 206 is low, which will not affect the counterweight. In addition, the first counterweight 206 is fixed by the sleeve 207 and the slide bar 208 instead of the rope in the existing equipment, avoiding shaking that affects the test results. The non-swaying circular plate 209 is also easier to cooperate with the first counterweight 206. Meanwhile, the third groove 93 is used to keep the center of gravity of the first counterweight 206 in the middle position, so that the force applied to the circular plate 209 is more even.

[0042] Because the fixed positions of different steel structure grid frames are at different heights, the relative positions of the circular plate 209 and the first counterweight 206 change when switching the detection object, affecting the alignment operation of the circular plate 209 with the first groove 91. At this time, the first telescopic cylinder 203 is activated, which drives the second support plate 202 to move upward. The second support plate 202 drives the parts on it to move upward, so that the uppermost first counterweight 206 contacts the positioning frame 2011. Since the shortest distance from the upper side of the circular plate 209 to the lower side of the positioning frame 2011 is equal to the shortest distance from the upper side of the first counterweight 206 to the top of the first groove 91, the circular plate 209 is aligned with the first groove 91 of the uppermost first counterweight 206. Subsequently, the first telescopic cylinder 203 only needs to drive the first counterweight 206 to move by a multiple of its thickness distance. The structure is simple and does not require complex program control or position sensor monitoring, which helps to reduce costs and improve efficiency.

[0043] Implementation Plan 2

[0044] Based on implementation plan 1, such as Figures 1-2 and Figures 7-8 As shown, the measuring unit includes a first connecting block 2012, a measuring block 2013, and a second counterweight 2014; the first connecting block 2012 is welded to the front side of the circular plate 209; the measuring block 2013 is slidably connected to the front side of the first connecting block 2012, and the measuring block 2013 is provided with scale lines, with the first connecting block 2012 located at the zero scale line; the measuring block 2013 is snapped into the second counterweight 2014, and the measuring block 2013 is automatically reset by the gravity of the second counterweight 2014, without the need for electrical control or manual adjustment.

[0045] The limiting unit includes a connecting frame 2015, an electric slide rail 2016, an electric slider 2017, an electric push rod 2018, and a limiting block 2019. The connecting frame 2015 is bolted to the front side of the first support plate 1. The electric slide rail 2016 is bolted to the rear side of the connecting frame 2015. The electric slider 2017 is slidably connected to the electric slide rail 2016. The electric push rod 2018 is fixedly connected to the rear side of the electric slider 2017. The telescopic end of the electric push rod 2018 is bolted to the limiting block 2019, which is made of high-density alloy material. The limiting block 2019 cooperates with the measuring block 2013, and the limiting block 2019 limits and blocks the measuring block 2013, so that the measuring block 2013 and the first connecting block 2012 can always slide relative to each other from the zero mark.

[0046] After the circular plate 209 is inserted into the first groove 91, the electric push rod 2018 pushes the limiting block 2019 to move below the second counterweight 2014. Then, the electric slider 2017 slides upward on the electric slide rail 2016, so that the limiting block 2019 contacts the second counterweight 2014. Then, the first telescopic cylinder 203 drives the second support plate 202 to move downward, so that the five first counterweights 206 at the top hang on the circular plate 209 and drive the circular plate 209 to move downward. The circular plate 209 drives the first connecting block 2012 to move downward, while the measuring block 2013 and the second counterweight 2014 are blocked and limited by the limiting block 2019, so that the first connecting block 2012 slides downward relative to the measuring block 2013. The scale value at the position where the first connecting block 2012 and the measuring block 2013 are aligned is read manually. This scale value is the steel structure. Before changing the first counterweight 206 hanging on the circular plate 209, the electric slider 2017 drives the electric push rod 2018 to move downwards. The electric push rod 2018 drives the limit block 2019 to move downwards away from the second counterweight 2014. The second counterweight 2014 drives the measuring block 2013 downwards by gravity, so that the zero mark of the measuring block 2013 is aligned with the first connecting block 2012 again. Then the steel structure space frame is repeatedly tested. In use, the second counterweight 2014 and the limit block 2019 cooperate to ensure that the first connecting block 2012 can always automatically reset to the zero mark position of the measuring block 2013 during the continuous testing of the steel structure space frame. This allows the operator to read only one value each time to continuously obtain the downward bending value of the steel structure space frame, without having to read two values ​​and calculate the difference each time, which improves convenience.

[0047] Implementation Plan 3

[0048] Based on implementation plan 2, such as Figures 1-2 and Figures 9-11 As shown, the suspension assembly includes a second connecting block 301, a hook 302, a locking unit, and a tensioning unit; the second connecting block 301 is welded to the upper end of the slide bar 208; the hook 302 is rotatably connected to the upper side of the second connecting block 301, and the hook 302 is made of alloy material; the locking unit is connected to the hook 302; and the tensioning unit is connected to the support frame 2.

[0049] The locking unit includes a second telescopic cylinder 303, a linkage block 304, a locking block 305, anti-slip components 306, and a fixing block 307. The second telescopic cylinder 303 is fixedly connected to the lower side of the hook 302. The telescopic end of the second telescopic cylinder 303 is fixedly connected to the linkage block 304. The linkage block 304 is slidably connected to the hook 302. The upper side of the linkage block 304 is bolted to the locking block 305, which locks the hook 302 onto the steel structure frame to prevent the hook 302 from shifting during the testing process. The upper side of the locking block 305 has a fourth groove 94, which cooperates with the fixing block 307. Several anti-slip components 306 are fixedly connected to the locking block 305. The anti-slip components 306 are made of rubber to improve the clamping stability. The end of the hook 302 is fixedly connected to the fixing block 307 to improve the clamping stability.

[0050] The tensioning unit includes a third telescopic cylinder 308 and a push block 309; the third telescopic cylinder 308 is bolted to the support frame 2; the telescopic end of the third telescopic cylinder 308 is fixedly connected to the push block 309, and a rubber pad or a sponge pad can be provided on the lower side of the push block 309; the push block 309 presses the hook 302 downward onto the steel structure grid frame to prevent paint or other substances on it from lifting the hook 302 and affecting the measurement of curvature changes.

[0051] After the steel structure frame is fixed, the hook 302 is manually rotated backward and then pulled upward. When the bent part of the hook 302 exceeds the steel pipe of the steel structure frame, the hook 302 is manually rotated back to its original position and pushed downward so that the hook 302 is hooked on the steel pipe. Then, the second telescopic cylinder 303 drives the linkage block 304 to move upward, and the linkage block 304 drives the locking block 305 to move upward, so that the locking block 305 and the hook 302 clamp the steel pipe, so as to prevent the hook 302 from slipping after the steel pipe bends during the test and affecting the results. At the same time, the anti-slip part 306 increases the friction with the steel pipe, which helps to improve the clamping stability. Meanwhile, the upward movement of the locking block 305 causes the fourth groove 94 on it to fit into the outside of the fixing block 307, further improving the clamping stability.

[0052] If there is a thick layer of paint or impurities on the surface of the steel pipe, the hook 302 will first flatten the paint layer or impurities after being pulled downwards, and then apply pressure to the steel pipe. This will cause the measured downward bending distance to include the thickness of the paint layer or impurities, which is greater than the actual downward bending distance, resulting in inaccurate test results. Therefore, when the hook 302 is hung on the steel pipe, the third telescopic cylinder 308 drives the push block 309 to move downwards and contact the circular plate 209. The push block 309 pushes the circular plate 209 downwards, the circular plate 209 drives the slide rod 208 downwards, the slide rod 208 drives the second connecting block 301 downwards, and the second connecting block 301 drives the hook 302 downwards, so that the hook 302 flattens the paint layer or impurities on the steel pipe and avoids them affecting the subsequent test results.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
