Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] The present invention discloses a detection device for building steel bars, which is mainly used in scenarios where the clamps of traditional detection equipment can only be adapted to steel bars of a specific diameter. When detecting steel bars of different diameters, the clamps need to be changed frequently, which is not only cumbersome to operate, but also greatly reduces the detection efficiency.

[0019] Reference Figures 1-8 A testing device for reinforcing steel bars in construction includes a base platform 1. Two movable platforms 3 are mounted on the top of the base platform 1. An angle gauge 4 is installed inside each movable platform 3, and an adjustable clamping assembly 10 is installed inside each movable platform 3. The adjustable clamping assembly 10 includes a U-shaped fixed platform 1001. A circular frame 1002 is fixedly connected to the top of the U-shaped fixed platform 1001. Two sliding groove holes are opened at the front end of the circular frame 1002. Two arc-shaped clamping elements 1013 are installed inside each sliding groove hole. Multiple flexible pads 1007 are installed inside the circular frame 1002. An adjusting plate 1006 is fixedly connected to the side of each flexible pad 1007 near the circular frame 1002.

[0020] Reference Figures 1-6The circular frame 1002 has multiple rectangular holes, and multiple connecting plates 1003 are fixedly connected inside each rectangular hole. A compression rod 1005 is fixedly connected to the side of each connecting plate 1003 near the flexible pad 1007, and an adaptation spring 1004 is fixedly connected to the side of each connecting plate 1003. The adaptation spring 1004 is located outside the compression rod 1005. The sides of the adaptation spring 1004 and the compression rod 1005 near the flexible pad 1007 are fixedly connected to the side of the adjusting plate 1006 away from the flexible pad 1007.

[0021] In this design, a ring-shaped component 1012 is fixedly connected to one side of the outer side of the circular frame 1002. A bidirectional motor 1011 is fixedly connected inside the ring-shaped component 1012. The power output shafts at both ends of the bidirectional motor 1011 are connected to threaded rods 1010 via couplings. Two symmetrical fixing plates 1008 are fixedly connected to the side of the circular frame 1002 closest to the bidirectional motor 1011. The opposite side of the fixing plate 1008 closest to the bidirectional motor 1011 is movably connected to the end of the threaded rod 1010 away from the bidirectional motor 1011.

[0022] In this design, guide rods 1009 are fixedly connected to the opposite side of the two fixed plates 1008 that are away from the bidirectional motor 1011. Two holes are opened at the ends of the two arc-shaped clamping parts 1013 that are close to the bidirectional motor 1011, and the interior of the holes is movably connected to the outside of the guide rods 1009 and the threaded rods 1010.

[0023] Specifically, when both ends of the reinforcing bar move with the moving platform 3 and extend into the circular frame 1002, the reinforcing bar comes into contact with the flexible pad 1007 and is compressed. After being compressed, the flexible pad 1007 pushes the adjusting plate 1006, which is fixedly connected to it, to move away from the reinforcing bar. When the adjusting plate 1006 moves, it drives the compression rod 1005 and the adapting spring 1004 connected to it to move synchronously. The compression rod 1005 and the adapting spring 1004 are compressed, thereby generating a reverse elastic force, which makes the flexible pad 1007 tightly fit against the outside of the reinforcing bar, realizing the initial flexible clamping of the reinforcing bar. It can adapt to reinforcing bars of different diameters. Afterwards, the bidirectional motor 1011 starts. The power output shafts at both ends drive the threaded rod 1010 to rotate via couplings. Since the fixing plate 1008 near the bidirectional motor 1011 is movably connected to the threaded rod 1010, and the fixing plate 1008 away from the bidirectional motor 1011 is fixedly connected to the guide rod 1009, when the threaded rod 1010 rotates, it will drive the two arc-shaped clamping parts 1013 to move along the guide rod 1009 and the threaded rod 1010 towards the direction of the reinforcing bar. The arc-shaped clamping parts 1013 slide in the sliding groove hole of the circular frame 1002, and finally clamp the reinforcing bar from both sides. In cooperation with the flexible pad 1007, the reinforcing bar is firmly fixed, which prepares for subsequent inspection operations.

[0024] In specific applications, it can adapt to steel bars of different diameters, eliminating the need for frequent clamp changes, thus improving testing efficiency. It also ensures that the steel bars do not shift during the testing process, guaranteeing the accuracy of the test results.

[0025] It should be noted that the flexible pad 1007 can prevent the rebar from being scratched or damaged during the clamping process, and is especially suitable for rebar inspection scenarios where surface quality is required.

[0026] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The top of the base platform 1 is provided with a movable bending weight assembly 13. The movable bending weight assembly 13 includes two linear rails 1301, and the bottom end of the linear rails 1301 is fixedly connected to the top of the base platform 1. The top of each linear rail 1301 is slidably connected with a sliding seat 1302.

[0027] In this design, a support plate 1306 is fixedly connected to the top of each of the two sliding seats 1302, a retaining frame 1303 is fixedly connected to one side of each sliding seat 1302, and a drive motor 1304 is fixedly connected to the inner side of each retaining frame 1303. The power output shaft of each drive motor 1304 is connected to a rotating shaft 1305 via a coupling.

[0028] In this design, pull ropes 1307 are wound around the outer sides of both rotating shafts 1305. Support plates 1306 are fixedly connected to the top of the sliding seats 1302. Annular guide members 1308 are fixedly connected to the opposite side of the support plates 1306. Pull ropes 1307 are movably connected inside the annular guide members 1308. Slots are provided on the support plates 1306. Support rods 1311 are slidably connected inside the slots. The bottom end of the support rods 1311 is fixedly connected to the top of the pull ropes 1307. Annular seats 1309 are fixedly connected to the opposite side of the annular guide members 1308. A weight placement plate 1310 is fixedly connected to the top of the annular seat 1309.

[0029] Specifically, the sliding seat 1302 can slide on the linear track 1301. By adjusting the position of the sliding seat 1302 on the linear track 1301, the position of the moving bending weight component 13 on the base platform 1 can be adjusted to meet the testing requirements of steel bars of different lengths. Then, the power output shaft of the drive motor 1304 drives the rotating shaft 1305 to rotate through the coupling. When the rotating shaft 1305 rotates, the pull rope 1307 wrapped on the outside is pulled downward. The pull rope 1307 moves downward inside the annular guide 1308. Since the bottom end of the support rod 1311 is fixed to the top end of the pull rope 1307 and the support rod 1311 is slidably connected to the slot of the support plate 1306, the downward pull of the pull rope 1307 will drive the support rod 1311 to move downward synchronously. The annular seat 1309, which is connected to the support rod 1311 and the annular guide 1308, moves downward, thereby causing the steel bar located in the annular seat 1309 to bend downward. At the same time, the staff places weights of different weights on the weight placement plate 1310 and observes the deformation of the steel bar under different weights to detect the maximum weight that the steel bar can withstand.

[0030] In specific application scenarios, the drive motor 1304 precisely controls the downward displacement of the ring seat 1309 by pulling the rope 1307, the ring guide 1308 and other components, so that the force and displacement during the bending process of the steel bar are controllable, ensuring the accuracy of the detection data.

[0031] Reference Figures 1-4 A scale 2 is fixedly connected to the front end of the base platform 1, and a displacement groove plate 5 is fixedly connected to the top end of the base platform 1. The bottom end of the moving platform 3 is slidably connected to the displacement groove plate 5 and the top end of the linear track 1301. Rotating rollers 11 are provided inside both moving platforms 3. Angle gauge 4 and U-shaped fixed platform 1001 are fixedly connected to the outside of the rotating rollers 11. Angle disks 6 are fixedly connected to the side of both moving platforms 3 near the scale 2. A pointer 7 is provided at the end of the rotating rollers 11 near the scale 2. Fixing parts 9 are fixedly connected to both sides of the moving platform 3. A lead screw 12 is provided inside the fixing parts 9. Locking threaded parts 8 are provided on the outer sides of both ends of the lead screw 12. The fixing parts 9 are located between two symmetrical locking threaded parts 8.

[0032] A method of using a testing device for reinforcing steel bars in construction, comprising the following steps: Step 1: The two moving platforms 3 move in opposite directions according to the length of the steel bar. The scale 2 displays the distance. The locking threaded part 8 fixes the screw 12 to keep the distance between the moving platforms 3 stable, so that the middle part of the steel bar is within the ring seat 1309. Step 2: When the reinforcing bar moves, push the adjusting plate 1006 inside the circular frame 1002, which drives the compression rod 1005, the adapting spring 1004 and the flexible pad 1007 to fit the reinforcing bar. The bidirectional motor 1011 drives the arc-shaped clamping piece 1013 to clamp the reinforcing bar. Step 3: The rotating roller 11 and angle table 4 display the bending angle of the steel bar; the sliding seat 1302 moves on the straight track 1301, and the drive motor 1304 pulls the ring seat 1309 to move the steel bar down by pulling the rope 1307. Weights are added to the weight placement plate 1310 to test the load-bearing capacity of the steel bar.
