Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7The diagram shows a rebar tensile testing device with monitoring function, including a distribution box 1 and a protective structure 2 installed on the top. The protective structure 2 includes a wire mesh cover 201, with a 202 installed on the rear end face of the wire mesh cover 201. A tempered glass cover 203 is fixedly connected to the front end face inside the wire mesh cover 201, and an industrial camera 204 is placed inside it. The top of the tempered glass cover 203 is open and is connected to a cover plate 205 by a hinge. Two insert plates 208 are fixedly connected to the closed side of the cover plate 205. The adjacent sides of the two insert plates 208 are connected to compression blocks 206 by compression springs 207. A wiring port 209 is opened at the bottom of the tempered glass cover 203.

[0024] It is worth noting that after opening the outer door panel 202, the steel bars to be tested for tensile strength are sent into the tensile test structure 3 for installation. After installation, the door panel 202 is closed, and the tensile test of the steel bars can be safely carried out inside the wire mesh cover 201. This effectively prevents the fragments from flying out during the tensile process, thereby improving the safety of the operation. During the test, the test footage can be recorded in real time by an industrial camera 204. The surrounding display screen can transmit the data to a nearby display screen 2016 via a WIFI module for real-time viewing of the test process. This effectively captures and records the tensile deformation of the steel bars, thereby improving the accuracy of the data acquisition for the tensile test of the steel bars.

[0025] Please see Figure 1 , Figure 7 and Figure 8 The industrial camera 204 has a built-in controller 2013 with electrical connections. The controller 2013 is electrically connected to a storage module 2011, a camera module 2012, a screenshot module 2014, and a WIFI module 2015. The industrial matrix camera 204 is electrically connected to an external power supply 2010 via wires and is powered by the external power supply 2010. The camera module 2012 controls the duration of the camera mode of the industrial matrix camera 204, and the screenshot module 2014 completes the entire video screenshot mode. This allows the test data to be stored via screenshots, and the test process to be stored via video mode. All data is stored on the storage module 2011 and can be remotely transmitted to the display screen 2016 via the WIFI module. The video mode can be used for experiments or teaching demonstrations, and the tensile process of the steel bars can be clearly observed. The screenshot module 2014 can acquire high-quality image data, which is of great value for the analysis of paper test data, helps in the processing of test data, the design of related components, and the optimization of the overall structure and motion performance of the device to ensure that it can accurately track and record the tensile deformation of the steel bars.

[0026] During the installation of the industrial camera 204, the cover plate 205 is opened, and the relevant wires are passed through the wiring port 209 and connected to the interface of the industrial camera 204. The industrial camera 204 is placed at the bottom inside the tempered glass cover 203. The cover plate 205 is closed, and the two insert plates 208 are inserted into the sides of the industrial camera 204. By squeezing the round block 206, the compression spring 207 is compressed, thereby squeezing the round block 206 into contact with the side of the industrial camera 204. Through the rebound force of the compression spring 207, the industrial camera 204 is fixed. Similarly, the cover plate 205 can be closed and placed stably, so that the industrial camera 204 works inside the tempered glass cover 203. This prevents the fragments generated by the breakage of the rib during the stretching process from flying and colliding, thus protecting the industrial camera 204.

[0027] Please see Figure 1 and Figure 4 A tensile testing structure 3 is installed on the top of the distribution box 1, inside the wire mesh cover 201. The tensile testing structure 3 includes a top block 301 and a lifting block 302. The top block 301 is located above the distribution box 1, and the lifting block 302 is located between the distribution box 1 and the lifting block 302. Two sliding rods 303 and two lead rods 3010 are connected to the upper surface of the distribution box 1. The two diagonally arranged sliding rods 303 and the two diagonally arranged lead rods 3010 are arranged in a rectangular shape. The top of the sliding rod 303 slides... A movable through-pull block 302 is formed, and the top of the lead screw 3010 is threaded through the pull block 302. The bottom of the top block 301 is fixedly connected to the top of the lead screw 3010 and the top of the slide bar 303. A motor 304 is installed on the top of the distribution box 1. The output end of the motor 304 is fixedly connected to the drive gear 306. Two diagonally arranged rotating shafts 305 are rotatably connected to the top of the distribution box 1. The bottom of the rotating shaft 305 is fixedly connected to the driven gear 309 that meshes with the drive gear 306. The bottom of the lead screw 3010 is fixedly connected to the rotating shaft 305.

[0028] It is worth noting that when the door panel 202 is opened, the reinforcing bar will be fed between the top block 301 and the lifting block 302 for installation. After installation, the door panel 202 is closed and the motor 304 is started. At this time, the driving gear 306 meshes with the two driven gears 309, thereby synchronously rotating the two lead screws 3010. This synchronous rotation can make the lifting block 302 rise or fall to adjust the clamping length of the reinforcing bar. When it is necessary to stretch the reinforcing bar, the lifting block 302 falls. The entire stretching process can be observed directly through the iron mesh cover 201. Whether for experiments or teaching demonstrations, the stretching state of the reinforcing bar can be clearly seen.

[0029] See Figure 4The top of the distribution box 1 is fixedly connected to a vertically installed measuring ruler 307. A lifting block 302 is located on the side of the measuring ruler 307 and a pointer 308 is fixedly connected. During the descent of the lifting block 302, the pointer 308 is moved synchronously, so that the length of the ruler 307 can be measured according to the displacement of the pointer 308. In this way, the tensile length that the steel wire can withstand can be accurately measured.

[0030] See Figure 4 The distribution box 1 is equipped with a partition 101 located below the drive gear 306. Several heat dissipation holes 102 are opened on both sides of the distribution box 1 above the partition 101. It should be noted that in order to ensure heat dissipation inside the working area of ​​the motor 304, the space below the partition 101 can accommodate various types of V-shaped plates 405. The V-shaped plates 405 with matching steel bar outer diameter can be replaced, and sealed storage can reduce the possibility of corrosion.

[0031] See Figure 4 , Figure 5 and Figure 6 Both the top block 301 and the lifting block 302 are equipped with clamping structures 4. The clamping structures 4 include hydraulic cylinders 401, sliders 404, and swing rods 408. Both the top block 301 and the lifting block 302 are provided with circular holes 4012, and hydraulic cylinders 401 are installed inside the circular holes 4012. The two hydraulic cylinders 401 are symmetrically arranged. A circular plate 409 is fixedly connected to the output end of the hydraulic cylinder 401. The other side of the circular plate 409 is slidably disposed in the circular hole 4012. The fixed connecting convex plate 406, the top block 301 and the lifting block 302 are provided with jaws 4010 on adjacent sides, and the jaws 4010 are provided with sliding grooves 4011 on both sides. The sliding grooves 4011 are slidably connected to the sliders 404. One end of the rocker arm 408 is rotatably connected to the convex plate 406 through the second pin 402, and the other end is rotatably connected to the sliders 404 through the second pin 402. V-shaped plates 405 are installed on adjacent sides of the two sliders 404.

[0032] It is worth noting that when the two ends of the reinforcing bar are inserted into the jaws 4010, the two hydraulic cylinders 401 are activated in sequence, dragging the circular plate 409 to move vertically. The two sliders 404 are dragged towards each other by the swing rod 408, so that the two ends of the reinforcing bar are pressed and fixed to the groove of the V-shaped plate 405.

[0033] See Figure 5 The front and rear sides of the V-shaped plate 405 are provided with an integrally formed mounting plate 407. The mounting plate 407 is detachably connected to the adjacent end face of the slider 404 by bolts 403. By unscrewing all the bolts 403, the V-shaped plate 405 and the mounting plate 407 can be disassembled together, and the V-shaped plate 405 and the mounting plate 407 that match the outer diameter of the steel bar can be replaced together.

[0034] It should be noted that its hydraulic cylinder 401 operates through a hydraulic system, which is installed near the equipment.

[0035] Working principle: When the door panel 202 is opened, the reinforcing bar is fed between the top block 301 and the lifting block 302 for installation. The two ends of the reinforcing bar are inserted into the jaws 4010, and the motor 304 is started. At this time, the driving gear 306 meshes with the two driven gears 309, thereby synchronously rotating the two lead screws 3010. This synchronous rotation causes the lifting block 302 to rise, thus conforming to the length of the reinforcing bar. Then, the two hydraulic cylinders 401 are activated in sequence, dragging the circular plate 409 to move vertically. The rocker arm 408 drags the two sliders 404 to move towards each other, so that the two ends of the reinforcing bar are pressed and fixed to the groove of the V-shaped plate 405. The door panel 202 is closed, and the motor 304 is started. At this time, the driving gear 306 meshes with the two driven gears 309, thereby synchronously rotating the two lead screws 3010. This synchronous rotation causes the lifting block 302 to fall. The entire stretching process can be recorded by the industrial camera 204. Whether for testing or teaching demonstration, the stretching state of the reinforcing bar can be clearly seen.
