Description

Technical Field

[0001] This application relates to the technical field of steel bar detection, and specifically relates to a non-destructive testing device for building steel bars. Background Art

[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete, and are one of the commonly used materials in construction projects. They are usually used to support the framework of buildings and enhance the strength of buildings. In order to ensure the quality and safety of construction projects, testing devices are usually required to perform non-destructive testing on steel bars.

[0003] The Chinese utility model patent with the publication number CN220740913U discloses a steel bar detection fixture, which includes a device main body and an adjustment mechanism arranged inside the device main body. The adjustment mechanism includes a rotation assembly and a sliding assembly; the rotation assembly includes an adjustment drive motor and a swing rod. A connecting plate is fixedly connected to the inner wall of the device main body. By setting an adjustment block, when detecting a steel bar through the steel bar detection fixture, in order to improve the convenience of detecting different positions of the steel bar and improve the accuracy of the detected data of the steel bar, the adjustment drive motor can be turned on to drive the swing rod to rotate, drive the slider to slide along the outer wall of the chute, the sliding of the slider drives the sliding rod to slide along the inner wall of the connecting plate, and the sliding of the sliding rod drives the adjustment block to slide along the outer wall of the limit groove, so as to play a role in detecting different positions of the steel bar, and realize the control operation of improving the detection accuracy of the steel bar when detecting the steel bar through the steel bar detection fixture.

[0004] The device is provided with a device main body, and an adjustment mechanism is arranged on the device main body. When performing a detection operation on a steel bar, first clamp the steel bar through the steel bar detection fixture, and then drive the swing rod to swing through the drive motor, and then drive the adjustment block to slide along the limit groove to realize the detection of different positions of the steel bar. However, when detecting a steel bar with a longer length, the staff needs to repeatedly adjust the opening and closing of the steel bar detection fixture, and then adjust the clamping and detection section of the steel bar, with cumbersome operations and low detection efficiency. Utility Model Content

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0025] Such as Figures 1-4As shown in the figure, an embodiment of the utility model discloses a non-destructive testing device for building steel bars, including a base 1 and a driving mechanism

[0026] The base 1 is provided with two groups of fixed blocks 2 at intervals. A clamping block 3 is arranged above the fixed block 2. An electric push rod 6 is fixedly arranged on one side of the base 1 corresponding to the fixed block 2. A counterbore 302 is arranged on the clamping block 3 and is equipped with the electric push rod 6. The output shaft of the electric push rod 6 is fixedly connected to the clamping block 3. A first groove 201 and a second groove 301 are respectively arranged on the fixed block 2 and the clamping block 3. A first roller 4 and a second roller 5 are respectively rotatably arranged in the first groove 201 and the second groove 301. A support frame 7 is fixedly arranged on the base 1. A scanner 8 is arranged at the bottom of the support frame 7. The driving mechanism is arranged on the fixed block 2.

[0027] In at least one embodiment, the driving mechanism includes a motor and a gear 203. An installation cavity 202 is arranged in the fixed block 2. The motor is fixedly arranged in the installation cavity 202. The output shaft of the motor is fixedly connected to the gear 203. One end of the first roller 4 is located in the installation cavity 202. A tooth groove 401 is arranged at the end of the first roller 4 located in the installation cavity 202 and is equipped with the gear 203. The staff starts the motor in the installation cavity 202. The motor drives the gear 203 to rotate. The gear 203 drives the first roller 4 to rotate through the cooperation of the tooth groove 401, so as to realize the movement of the steel bar on the first roller 4, and the operation is convenient.

[0028] In at least one embodiment, sliding grooves are arranged on both sides of the second groove 301. Sliders 303 are slidably arranged in the sliding grooves. Two ends of the second roller 5 are respectively rotatably connected to a group of sliders 303. A spring 304 is arranged on one side of the sliding groove far away from the second roller 5. Two ends of the spring 304 are respectively fixedly connected to the slider 303 and the clamping block 3. When the electric push rod 6 drives the clamping block 3 and the second roller 5 to descend, when the second roller 5 abuts against the top of the steel bar and continues to descend, it will drive the two side sliders 303 to slide along the sliding grooves and compress the spring 304, so as to avoid damage when the second roller 5 directly abuts against the steel bar.

[0029] In at least one embodiment, arc grooves are arranged on both the first roller 4 and the second roller 5. By arranging the arc grooves, it is convenient to effectively clamp the steel bars.

[0030] In at least one embodiment, a plurality of groups of rubber pads are arranged at intervals along the circumferential direction in the arc grooves. By arranging the rubber pads, it is avoided that the first roller 4 and the second roller 5 directly abut and collide with the steel bars, ensuring the safety of the equipment.

[0031] In at least one embodiment, a clamping block is fixedly arranged on the fixed block 2. A limiting groove 305 is arranged on the clamping block 3 and is equipped with the clamping block. By arranging the clamping block, the clamping block 3 is limited, ensuring the stability of the lifting of the clamping block 3.

[0032] In at least one embodiment, the clamping blocks are provided in multiple groups and arranged at intervals on the fixed block 2. By providing multiple groups of clamping blocks, multi-point limit is imposed on the clamping block 3, further ensuring the stability of the clamping block 3 during upgrading.

[0033] When performing the detection operation on the steel bar, the staff places the steel bar on the base 1 and places the two ends of the steel bar on two groups of fixed blocks 2 respectively, so that the first roller 4 on the fixed block 2 abuts against the bottom of the steel bar. Then, the staff starts the electric push rod 6, so that the output shaft of the electric push rod 6 drives the clamping block 3 to descend. Finally, the second roller 5 on the clamping block 3 abuts against the top of the steel bar. Multi-point clamping of the steel bar to be detected is achieved through the first roller 4 and the second roller 5 on the two groups of fixed blocks 2. Then, the staff starts the scanner 8 on the support frame 7, and scans and images the steel bar section between the two groups of fixed blocks 2 through the scanner 8. Further, the staff can judge and detect the steel bar based on the scanning result. When the length of the steel bar to be monitored is relatively long, the staff can drive the first roller 4 on the fixed block 2 to rotate through the driving mechanism, so that the steel bar moves along the two groups of first rollers 4, and the detection operation on different clamping sections can be realized. The operation is convenient and the detection efficiency is improved.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
