Description

Technical Field

[0001] This invention relates to the field of rebar testing technology, specifically to a rebar strength testing device for quality testing in building engineering. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. They are mainly used in various large, heavy, light, thin-walled and high-rise building structures. Reinforcing bar processing generally involves four processes: rust removal, straightening, cutting, and forming. Their cross-section is circular, sometimes square with rounded corners, and they are divided into three types: plain round bars, ribbed bars, and twisted bars.

[0003] For the bending strength testing of reinforcing bars, multiple tests are required on multiple groups of reinforcing bars of the same type. The judgment and results are obtained by comprehensively analyzing the experimental data. The existing technology requires the reinforcing bars to be cut into multiple segments before being tested in sequence. In addition, manual loading is required, which makes the reinforcing bar strength testing steps in the existing technology cumbersome and has a low degree of automation, resulting in low efficiency in actual operation. Summary of the Invention

[0009] Preferably, the pressure plate is cone-shaped, and multiple anti-slip strips are fixedly connected to the cone surface of the pressure plate. The multiple anti-slip strips are arranged in a circumferential array, and the multiple anti-slip strips are made of soft rubber material.

[0010] Preferably, a second AC motor is fixedly connected to the top of the base, and a drive pulley is fixedly connected to the outer wall of the output shaft end of the second AC motor.

[0014] The present invention has the following beneficial effects:

[0015] 1. This steel reinforcement strength testing equipment for construction engineering quality inspection automatically feeds and conveys steel reinforcement through a feeding assembly, eliminating the need for continuous manual feeding operations and enhancing the equipment's usability. The output shaft of the first AC motor drives the active synchronous pulley to rotate, which in turn drives two passive synchronous pulleys to rotate synchronously under the transmission of the synchronous belt. This, in turn, drives the conveyor rollers fixedly connected to the two passive synchronous pulleys to rotate. Through the meshing of four reversing gears, the two vertically distributed conveyor rollers rotate in opposite directions, thereby driving the pressure plate to rotate and engage the steel reinforcement for feeding. When the pressure plate engages the steel reinforcement, multiple tension springs are subjected to reverse pressure, causing the tension springs to extend and generate elasticity. This elasticity further pushes the pressure plate, firmly clamping it onto the outer wall of the steel reinforcement, thereby increasing the conveying friction and further improving the conveying efficiency of the feeding assembly.

[0016] 2. This steel reinforcement strength testing equipment for construction engineering quality inspection drives the active pulley to rotate via the output shaft of the second AC motor. Under the transmission of the belt, the passive pulley rotates, which in turn drives the power rod to rotate inside the cutting support base. This, in turn, drives the two worm gears to rotate, causing the two worm wheels meshing with the worm gears to rotate in opposite directions. This, in turn, drives the two cutting rollers to rotate, which in turn drives the two cutting heads to rotate. As the two cutting heads rotate, they cut the steel reinforcement, thus slicing the steel reinforcement. This eliminates the need for pre-cutting the steel reinforcement, further improving the ease of use of the equipment. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0027] Please see Figure 1-8 A steel reinforcement strength testing device for construction engineering quality testing includes a base 1, a feeding component 2 and a cutting component 3 fixed on the top of the base 1, the feeding component 2 being located to the left of the cutting component 3, and a testing component 4 fixed on the top of the base 1, the testing component 4 being located to the right of the cutting component 3.

[0028] The feeding assembly 2 includes two feeding support seats 201 distributed front and rear. Both feeding support seats 201 are fixedly connected to the top of the base 1 by bolts. Four conveying rollers 202 are rotatably connected between the two feeding support seats 201. Tensioning tubes 203 are fixedly connected to the middle of the outer wall of each of the four conveying rollers 202. Two pressure plates 204 are slidably connected to the outer wall of each tensioning tube 203. Two fixing blocks 205 are fixedly connected to the outer wall of each tensioning tube 203. The two fixing blocks 205 are located outside the two pressure plates 204. Multiple tension springs 206 are fixedly connected to the side of each fixing block 205 near the two pressure plates 204. The multiple tension springs 206 are arranged in a circumferential array. Multiple tension springs 206 are distributed such that the ends of the springs 206 furthest from the two fixed blocks 205 are fixedly connected to one side of the two pressure plates 204. The pressure plates 204 are conical in shape, and multiple anti-slip strips 2010 are fixedly connected to the conical surface of the pressure plates 204. The anti-slip strips 2010 are arranged in a circumferential array and are made of soft rubber. A passive synchronous pulley 2011 is fixedly connected to the front end of each of the two conveyor rollers 202. A synchronous belt 2012 is fitted around the two passive synchronous pulleys 2011. An active synchronous pulley 2013 is connected to the end of the synchronous belt 2012 furthest from the two passive synchronous pulleys 2011. The active synchronous pulley 2013 is positioned... At the bottom of the two passive synchronous pulleys 2011, the top of the base 1 is fixedly connected to a first AC motor 2014. The output shaft of the first AC motor 2014 is fixedly connected to the shaft hole of the active synchronous pulley 2013. The rear ends of the four conveying rollers 202 are all fixedly connected to reversing gears 2015, with the two reversing gears 2015 distributed vertically meshing with each other. The feeding assembly 2 automatically feeds and conveys the steel bars, eliminating the need for continuous manual feeding and improving the usability of the equipment. The output shaft of the first AC motor 2014 drives the active synchronous pulley 2013 to rotate, which in turn drives the two passive synchronous pulleys 2011 to synchronize under the transmission action of the synchronous belt 2012. The rotation drives the conveying rollers 202, which are fixedly connected to the two passive synchronous wheels 2011, to rotate. Under the meshing action of the four reversing gears 2015, the two vertically distributed conveying rollers 202 rotate in opposite directions, thereby driving the pressure plate 204 to rotate and bite the steel bars for conveying and feeding. When the pressure plate 204 bites the steel bars, multiple spring tension springs 206 are subjected to reverse pressure, causing the tension springs 206 to be extended and generate elasticity. Under the elastic force of the multiple tension springs 206, the pressure plate 204 is pushed and firmly clamped on the outer wall of the steel bars, thereby increasing the conveying friction of the steel bars and further improving the conveying efficiency of the block feeding assembly 2.

[0029] The cutting assembly 3 includes a cutting support base 301. Two cutting rollers 302, distributed front to back, are rotatably connected to the top of the cutting support base 301. The two cutting rollers 302 extend into the interior of the cutting support base 301. A cutter wheel 303 is fixedly connected to the outer wall of each of the two cutting rollers 302, and a cutter head 304 is fixedly connected to the outer wall of each of the two cutter wheels 303. A second AC motor 305 is fixedly connected to the top of the base 1. A drive pulley 306 is fixedly connected to the outer wall of the output shaft end of the second AC motor 305. A leather belt is sleeved around the drive pulley 306. A belt 307 is connected to a driven pulley 308 at the end away from the driving pulley 306. A drive rod 309 is fixedly connected to the shaft hole of the driven pulley 308. The drive rod 309 is rotatably connected to the inside of the cutting support 301. Two worm gears 3010 are fixedly connected to the outer wall of the drive rod 309. The two worm gears 3010 are located on both sides of the driven pulley 308 and are arranged in opposite spirals. A worm wheel 3011 meshes with one side of each of the two worm gears 3010. The two worm wheels 3011 are respectively connected to the bottom of the two cutting rollers 302. When the steel bars are conveyed to the inside of the detection component 4 via the feeding assembly 2, they are placed in the top grooves of the two I-beam pulleys 403. At this time, the ends of the steel bars are in contact with the position sensor 6. After receiving the position signal of the steel bars, the position sensor 6 transmits the signal to the inside of the control box 7. After processing by the control box 7, the power supply to the first AC motor 2014 is stopped, and the second AC motor 305 is started. The output shaft of the second AC motor 305 drives the drive pulley 306 to rotate, so that under the transmission action of the belt 307, The passive pulley 308 rotates, which in turn drives the power rod 309 to rotate inside the cutting support 301, and drives the two worm gears 3010 to rotate. This causes the two worm wheels 3011 meshing with the two worm gears 3010 to rotate in opposite directions, driving the two cutting rollers 302 to rotate. This further causes the two cutter wheels 303 to rotate, driving the two cutter heads 304 to rotate. As the two cutter heads 304 rotate, they cut the steel bars, thus slicing the steel bars. This eliminates the need for pre-cutting the steel bars, further improving the ease of use of the equipment.

[0030] In this embodiment, a plurality of torsion limiting holes 207 are provided through one side of the fixing block 205 near the pressure plate 204. The plurality of torsion limiting holes 207 are arranged in a circumferential array. The interior of each of the plurality of torsion limiting holes 207 is slidably connected to a torsion limiting rod 208. The ends of the plurality of torsion limiting rods 208 are fixedly connected to the outer side of the pressure plate 204. The ends of the plurality of torsion limiting rods 208 away from the pressure plate 204 are jointly fixedly connected to a connecting block 209. The connecting block 209 is fixedly connected to the outer wall of the tensioning tube 203. By setting the torsion limiting holes 207 and the torsion limiting rods 208 to slide, the pressure plate 204 is torsion-limited, preventing the pressure plate 204 and the tensioning tube 203 from rotating relative to each other. This ensures that the tensioning tube 203 has sufficient driving force to rotate the pressure plate 204, and ensures the effect of the fixing block 205 in conveying and feeding the steel bars.

[0031] In this embodiment, two vertically distributed guard strips 3012 are fixedly connected to the outer walls of both cutter wheels 303, and two rotatably connected retaining sleeves 3013 are rotatably connected to the outer walls of both cutting rollers 302. The retaining sleeves 3013 are located at the top of the cutter wheels 303, and a connecting rod 3014 is fixedly connected between the two retaining sleeves 3013. By setting the two guard strips 3012, the upper and lower guard strips can limit the upper and lower movement of the steel bars, preventing the steel bars from bouncing when the two cutter heads 304 cut the steel bars. By setting the two retaining sleeves 3013 and the connecting rod 3014, a retaining force is provided to the top of the two cutting rollers 302 towards the middle, so that when the two cutter heads 304 cut the steel bars, the two cutting rollers 302 are prevented from bending and deforming to both sides when the two cutter wheels 303 are subjected to the reverse force of the steel bars, thereby improving the overall strength of the cutting assembly 3.

[0032] In this embodiment, the detection component 4 includes two detection platforms 401 distributed front to back. Two support holes 402 are provided on the opposite surfaces of the two detection platforms 401, distributed left to right. I-shaped wheels 403 are rotatably connected to the interiors of the two left support holes 402 and the two right support holes 402. A fixed platform 404 is fixedly installed on the top of the base 1, above the two detection platforms 401. A hydraulic cylinder 405 is fixedly connected to the center of the top of the fixed platform 404. The output rod of the hydraulic cylinder 405 moves through the fixed platform 404 and extends to its bottom. A contact head 406 is fixedly connected to the bottom of the output rod of the hydraulic cylinder 405, located between the two I-shaped wheels 403. Support frames 407 are fixedly connected to the four corners of the bottom of the fixed platform 404. The four support frames 407 are fixedly connected to the top of the base 1. A control box 7 is fixedly connected to the top of the fixed platform 404, on one side of the hydraulic cylinder 405. The output terminal of the control box 7 is electrically connected to the input terminals of the first AC motor 2014, the second AC motor 305, and the hydraulic cylinder 405. A bend bracket 5 is fixedly connected to the top of the base 1, on one side of the detection component 4. A position sensor 6 is fixedly connected to the upper left side of the bend bracket 5. The output terminal of the position sensor 6 is electrically connected to the input terminal of the control box 7. After the cutting component 3 completes the cutting of the reinforcing bars, the control box 7 adjusts the experimental data and then starts the hydraulic cylinder 405. The output rod of the hydraulic cylinder 405 drives the pressure head 406 downwards, thereby pressing down the reinforcing bar segment mounted on top of the two I-shaped wheels 403 to perform bending strength testing. After the test is completed, the bent reinforcing bar segment is removed from the detection component 4. At this time, the control box 7 restarts the detection component 4 to transport the reinforcing bars, thus continuing the above operation process to continuously test the reinforcing bars.

[0033] Working principle: First, the feeding assembly 2 automatically feeds and conveys the steel bars, eliminating the need for continuous manual feeding and improving the equipment's usability. The output shaft of the first AC motor 2014 drives the active synchronous wheel 2013 to rotate, which in turn drives the two passive synchronous wheels 2011 to rotate synchronously under the transmission of the synchronous belt 2012. This, in turn, drives the conveying rollers 202, which are fixedly connected to the two passive synchronous wheels 2011, to rotate. Through the meshing action of four reversing gears 2015, the two vertically distributed conveying rollers 202 rotate in opposite directions, thereby driving the pressure plate 204 to rotate and engage the steel bars for feeding. When the pressure plate 204 engages the steel bars, multiple tension springs 206 are subjected to reverse pressure, causing the tension springs 206 to extend and generate elasticity. Under the elastic force of the multiple tension springs 206, the pressure plate 204 is pushed and firmly clamped onto the outer wall of the steel bars, thereby increasing the conveying friction of the steel bars and further improving the conveying efficiency of the feeding assembly 2.

[0034] When the reinforcing bars are conveyed to the inside of the detection component 4 by the feeding component 2, the reinforcing bars are placed in the top grooves of the two I-beam pulleys 403. At this time, the ends of the reinforcing bars are in contact with the position sensor 6. After receiving the position signal of the reinforcing bars, the position sensor 6 transmits the signal to the inside of the control box 7. After processing by the control box 7, the power supply to the first AC motor 2014 is stopped, and the second AC motor 305 is started. The output shaft of the second AC motor 305 drives the drive pulley 306 to rotate, so that under the transmission action of the belt 307, the reinforcing bars are driven to rotate. The rotation of the pulley 308 further drives the power rod 309 to rotate inside the cutting support 301, and drives the two worm gears 3010 to rotate, causing the two worm wheels 3011 meshing with the two worm gears 3010 to rotate in opposite directions, driving the two cutting rollers 302 to rotate, and further causing the two cutter wheels 303 to rotate, driving the two cutter heads 304 to rotate. When the two cutter heads 304 rotate, they cut the steel bars, thereby slicing the steel bars, thus eliminating the need for pre-cutting the steel bars and further improving the ease of use of the equipment;

[0035] After the cutting component 3 completes the cutting of the steel bars, the experimental data is adjusted by the control box 7, and the hydraulic cylinder 405 is started. The output rod of the hydraulic cylinder 405 drives the pressure head 406 to move downward, thereby pressing down the steel bar segment mounted on the top of the two I-shaped wheels 403 to perform bending strength testing. After the test is completed, the bent steel bar segment is removed from the inside of the testing component 4. At this time, the testing component 4 is started again by the control box 7 to transport the steel bars, thereby continuing the above operation process to continuously test the steel bars.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
