Description

Technical Field

[0001] This utility model relates to the field of steel bar corrosion detection technology, specifically to a non-destructive testing device for corrosion of reinforced concrete structures. Background Technology

[0002] Reinforced concrete, due to its inherent superior properties, has become the primary construction material in the building industry, and to a large extent, directly determines the safe and stable operation of concrete structures. However, due to the influence of surrounding environmental factors, the reinforcing steel inside concrete can undergo oxidation, defects, and other deterioration phenomena to a certain extent. Oxidation and corrosion can drastically alter the structural properties of the internal reinforcing steel, severely impacting the stability of the building. Therefore, before reinforced concrete is put into actual operation, it is necessary to conduct testing and research on the degree of corrosion of its internal reinforcing steel to provide safety assurance for its actual operation.

[0003] For example, the integrated platform for microwave non-destructive testing simulation of corrosion in reinforced concrete structures disclosed in Chinese patent application CN202211548965.5 specifically includes: a sliding table support A comprising a first transverse guide rail, a second transverse guide rail, a horizontal guide rail, a vertical guide rail, and a base. The lower part of the vertical guide rail is mounted on the base, which is used to fix the sliding table support A to ensure stability. The upper part of the vertical guide rail is mounted with a horizontal guide rail via a first slider, and a second slider can move up and down on the vertical guide rail. One end of the first transverse guide rail is mounted with a second slider at one end of the horizontal guide rail, and the second slider can move horizontally on the horizontal guide rail. The other end of the first transverse guide rail is mounted with a first rectangular waveguide via a first clamp. One end of the second transverse guide rail is mounted with a third slider at the other end of the horizontal guide rail, and the third slider can move horizontally on the horizontal guide rail. The other end of the second transverse guide rail is mounted with a second clamp, and the first and second rectangular waveguides are used to transmit / receive microwave signals. The test platform includes a test bench E for placing and leveling the concrete specimen D. The concrete specimen D is placed on the test bench E, between the first and second rectangular waveguides, maintaining a stable horizontal position between the specimen D and the base. The rectangular waveguides are fixed to the slide table support A using the screw knobs of the slider. The vertical slider of the slide table support A is adjusted to control the height of the rectangular waveguides, ensuring they are aligned with the overall height of the concrete specimen D. The horizontal slider is adjusted to control the spacing between the rectangular waveguides and the concrete specimen D. The transverse slider is adjusted to control the specific position of the rectangular waveguides and ensure they are aligned linearly. Through the use of this platform, the following technical problems were found:

[0004] Reinforced concrete has four sides. In actual use, reinforced concrete is tied into a steel cage and then concrete is poured. The steel cage is located in the middle of the concrete column. However, the first and second clamps in the existing technology can only drive the first and second rectangular waveguides to detect two sides of the reinforced concrete. It is difficult to detect the other two sides, resulting in insufficient detection of the reinforcement range. Utility Model Content

[0005] Therefore, this utility model provides a non-destructive testing device for corrosion of reinforced concrete structures to solve the problem that the existing technology is not comprehensive enough in detecting the range of reinforcing bars.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A non-destructive testing device for corrosion of reinforced concrete structures, including an analyzer, a computer, and a testing device for easy testing of reinforced concrete blocks;

[0008] One end of the detection device is equipped with an adjustment device for controlling the left and right movement of the detection device.

[0009] One end of the adjusting device is equipped with a support column, and the middle of the support column is equipped with a first reciprocating screw for cooperating with the adjusting device to control the detection device to move up and down.

[0010] The detection device includes a support frame, with first rectangular waveguides installed at both the front and rear ends of the support frame to facilitate the detection of reinforced concrete blocks. A scanning component is installed in the middle of the support frame, and the scanning component includes a second rectangular waveguide. A fixing block is installed at the upper end of the second rectangular waveguide, and a handle is installed at one end of the fixing block to facilitate the steering of the second rectangular waveguide.

[0011] The detection device includes a crossbar, one end of which is equipped with a limiting disk for angle locking of the second rectangular waveguide.

[0012] Furthermore, a support platform for supporting the reinforced concrete block is installed at the lower end of the reinforced concrete block, and a first screw nut for cooperating with the first reciprocating screw to control the adjustment device to move up and down is installed at the rear end of the adjustment device. A first motor for controlling the rotation of the first reciprocating screw is installed at the upper end of the first reciprocating screw.

[0013] Furthermore, a gear is installed in the middle of the adjusting device, a rotating rod is installed at the upper end of the gear, and a second motor is installed at the upper end of the rotating rod to cooperate with the rotating rod to control the rotation of the gear.

[0014] Furthermore, a crossbeam for supporting the support frame is installed on the upper left side of the support frame, and a limiting groove for facilitating the rotation of the gear is machined in the middle of the crossbeam.

[0015] Furthermore, a gear rod is installed on one side of the cavity of the limiting groove to cooperate with the gear to control the horizontal frame to move left and right.

[0016] Furthermore, a second reciprocating screw is installed at the lower end of the crossbar, and a third motor for controlling the rotation of the second reciprocating screw is installed at the left end of the second reciprocating screw.

[0018] Furthermore, a connecting tube for limiting the position of the fixing block is installed on the left side of the fixing block in conjunction with the crossbar. The upper and lower side walls of the left side of the connecting tube are fitted with locking blocks that engage with the locking slot. A spring is installed inside the connecting tube.

[0019] This utility model has the following advantages:

[0020] When inspecting the reinforcing bars inside the reinforced concrete block, the first motor controls the support platform to rotate, which in turn controls the adjustment device and the inspection device to move upward. Then, the second motor is started, and the rotating rod drives the gear to rotate. Under the action of the rack, the inspection device moves to the right, which facilitates the inspection of the front, rear, and top ends of the reinforcing bars. Then, the gear and rack control the inspection device to move to the left to reset. Pulling the handle to the right causes the locking block to disengage from the slot and rotates the fixing block 180 degrees. When the handle is released, the locking block engages with the slot, so that the second rectangular waveguide is at the top, which facilitates the inspection of the reinforcing bars from below the reinforced concrete block. The third motor is started, which causes the second reciprocating screw and the second screw nut to drive the crossbar and scanning assembly to move to the right. The second rectangular waveguide moves to the right in sync, which facilitates the inspection of the reinforcing bars. Attached Figure Description

[0034] Please see Figures 1-5 This utility model provides a non-destructive testing device for corrosion of reinforced concrete structures, including an analyzer 2, a computer 3, and a testing device 300 for easy testing of reinforced concrete blocks 1.

[0035] A support platform 10 is installed at the lower end of the reinforced concrete block 1 to support it, and the middle part of the support platform 10 is hollowed out to facilitate inspection. An adjustment device 100 for controlling the left and right movement of the inspection device 300 is installed at the left end of the inspection device 300.

[0036] A support column 200 is installed at the rear end of the adjusting device 100. A first reciprocating screw 210 is installed in the middle of the support column 200 to cooperate with the adjusting device 100 to control the detection device 300 to move up and down.

[0037] The rear end of the adjusting device 100 is fixedly equipped with a first screw nut 110 for cooperating with the first reciprocating screw 210 to control the adjusting device 100 to move up and down. After the first motor 211 is started, it drives the first reciprocating screw 210 to rotate, which in turn drives the adjusting device 100 to move up and down in cooperation with the first screw nut 110, and synchronously drives the detection device 300 to move up and down, so as to facilitate the detection of the reinforced concrete block 1.

[0038] A gear 120 is installed in the middle of the adjusting device 100. A rotating rod 121 is fixedly installed on the upper end of the gear 120.

[0039] The detection device 300 includes a support frame 310. First rectangular waveguides 311 are fixedly installed at both the front and rear ends of the support frame 310 to facilitate the detection of the reinforced concrete block 1. During the detection of the reinforced concrete block 1, the two first rectangular waveguides 311 are positioned at the front and rear ends of the reinforced concrete block 1, respectively. A crossbeam 320 for supporting the support frame 310 is fixedly installed at the upper left side of the support frame 310. A limiting groove 321 for facilitating the rotation of the gear 120 is machined in the middle of the crossbeam 320.

[0040] The rear end of the limiting groove 321 is fixedly equipped with a rack 330 for cooperating with the gear 120 to control the horizontal frame 320 to move left and right. When the second motor 122 controls the rotating rod 121 to rotate, the gear 120 and the rack 330 synchronously drive the horizontal frame 320 to move left and right, so that the first rectangular waveguide 311 can detect the dry reinforced concrete structure.

[0041] A second reciprocating screw 340 is installed at the lower end of the crossbar 320, and a third motor 341 for controlling the rotation of the second reciprocating screw 340 is installed at the left end of the second reciprocating screw 340.

[0042] A scanning assembly 350 is installed in the middle of the support frame 310. The scanning assembly 350 includes a second rectangular waveguide 351. While the first rectangular waveguide 311 is detecting the front and rear ends of the reinforced concrete block 1, the second rectangular waveguide 351 is simultaneously detecting the upper end of the reinforced concrete block 1. A fixing block 352 for limiting the second rectangular waveguide 351 is fixedly installed at the upper end of the second rectangular waveguide 351.

[0043] The detection device 300 includes a crossbar 360, a vertical bar 361 fixedly installed at the left end of the crossbar 360, a second lead screw nut 362 fixedly installed at the upper end of the vertical bar 361 for cooperating with the second reciprocating lead screw 340 to control the scanning assembly 350 to move left and right, a limiting plate 363 for angle locking of the second rectangular waveguide 351 fixedly installed at the right end of the crossbar 360, slots 364 are opened on the upper and lower side walls of the right side of the limiting plate 363, and a limiting block 365 is fixedly installed at the right end of the crossbar 360.

[0044] A connecting tube 353 is fixedly installed on the left side of the fixing block 352 to limit the fixing block 352 in conjunction with the crossbar 360. The upper and lower side walls on the left side of the connecting tube 353 are fixedly installed with locking blocks 354 that engage with the locking groove 364. A spring 355 is installed inside the connecting tube 353 to push the limiting block 365 to the right, so that the locking block 354 is always locked in the groove of the locking groove 364.

[0045] When inspecting the reinforcing bars within the reinforced concrete block 1, the first motor 211 controls the support platform 10 to rotate, which in turn controls the adjusting device 100 and the inspection device 300 to move upwards in conjunction with the first lead screw nut 110. Then, the second motor 122 is started, and the rotating rod 121 drives the gear 120 to rotate. Under the action of the rack 330, the inspection device 300 moves to the right, facilitating the inspection of the front, rear, and upper ends of the reinforcing bars. Subsequently, the gear 120, in conjunction with the rack 330, controls the inspection device 300 to move to the left to reset, and the handle 356 is then engaged. Pulling to the right disengages the locking block 354 from the slot 364 and rotates the fixing block 352 180 degrees. When the handle 356 is released, the locking block 354 engages with the slot 364, positioning the second rectangular waveguide 351 at the top to facilitate inspection of the reinforcing bars from below the reinforced concrete block 1. The third motor 341 starts, causing the second reciprocating screw 340, in conjunction with the second screw nut 362, to move the crossbar 360 and the scanning assembly 350 to the right. The second rectangular waveguide 351 moves synchronously and gradually to the right to facilitate inspection of the reinforcing bars.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
