Description
Technical Field
[0001] The present invention belongs to the field of steel bar detectors, and particularly relates to a concrete steel bar detector and method based on phased array ultrasonic waves. Background Art
[0002] A concrete steel bar detector based on phased array ultrasonic waves (hereinafter referred to as the steel bar detector) is an advanced device that uses phased array ultrasonic testing (PAUT) technology to achieve non-destructive and high-precision imaging detection of steel bars inside concrete. It dynamically adjusts the direction and focusing depth of the ultrasonic beam through an electronically controlled multi-element probe, overcoming the limitations of traditional ultrasonic testing, and is particularly suitable for steel bar positioning, diameter measurement, cover thickness evaluation, and defect detection in complex concrete structures.
[0003] Currently, when using the steel bar detector, it is usually manually held by an operator and attached to the wall surface, and then the steel bar detector is controlled to move horizontally for scanning detection. Finally, the operator uses a marker pen to mark each detection position.
[0004] The above-mentioned steel bar detector has the following defects in actual use:
[0005] 1) When the steel bar detector needs to scan and detect a wall surface at a relatively high position from the ground, a steel bar detector equipped with a bracket needs to be used for detection. After the steel bar detector is lifted to a relatively high position and attached to the wall surface by the bracket, the operator needs to bear the gravity of the bracket and the steel bar detector. At this time, it is very difficult for the operator to control the overall movement of the steel bar detector on the same horizontal plane of the wall surface, and the detection accuracy is difficult to guarantee.
[0006] 2) After scanning a high position on the wall surface with the steel bar detector, it is not convenient for the operator to mark this position, and it may require the cooperation of multiple people to complete, which is not convenient for single-operator operation. Summary of the Invention

[0022] Compared with the prior art, a concrete reinforcing bar detector and method based on phased array ultrasonic provided by an embodiment of the present invention have the following beneficial effects:
[0023] 1.

Detailed implementation manners
[0035] The following will Figure 1 - Figure 8 make a further detailed description of the present application.
[0036] Please refer to Figure 1 , Figure 2 and Figure 5 , a concrete reinforcing bar detector based on phased array ultrasonic waves, which is used to detect the position of reinforcing bars inside a wall. The concrete reinforcing bar detector includes a reinforcing bar detector body 1 and an auxiliary fixing frame 2 which is connected to the reinforcing bar detector body 1 and can be folded and stored in multiple sections. The auxiliary fixing frame 2 includes a horizontal guide rail 21. Connecting and sliding parts 22 are symmetrically arranged on the upper and lower sides of the horizontal guide rail 21. An upper support beam 23 connected to the reinforcing bar detector is arranged on the upper connecting and sliding part 22. A holding part 24 for controlling its horizontal sliding is arranged on the upper support beam 23. A lower support beam 25 is arranged on the lower connecting and sliding part 22. A locking part 26 for locking the lower connecting and sliding part 22 is arranged on the lower connecting and sliding part 22. A supporting part 27 in contact with the ground for fixing is arranged on the lower support beam 25.
[0037] It should be noted that the working process of the steel bar detector body 1 is as follows: ultrasonic waves are emitted by each element of the phased array sensor according to a set delay sequence to form a focused beam and propagate into the concrete. When the beam encounters a steel bar, a reflected echo is generated due to the difference in acoustic impedance. If there are defects such as corrosion and fracture in the steel bar, the characteristics of the echo will change. Then, the same sensor or an independent receiving element collects the reflected echo, records parameters such as the amplitude, propagation time (acoustic time), and phase of the signal, and reconstructs the position, size, and defect image of the steel bar through signal processing algorithms (such as total focusing imaging TFM and synthetic aperture focusing imaging SAFT). Finally, data processing and imaging are performed to construct a three-dimensional image of the interior of the concrete, clearly presenting the steel bar network structure.
[0038] During specific operation, the horizontal guide rail 21 is horizontally attached to the wall surface. The lower connecting and sliding part 22 slides to the middle position below the horizontal guide rail 21. Then, the lower support beam 25 rotates by a certain angle to be perpendicular to the horizontal guide rail 21, and the connecting and sliding part 22 is locked on the horizontal guide rail 21 through the locking part 26 and no longer moves. At the same time, the upper support beam 23 directly rotates by a certain angle through the upper connecting and sliding part 22 to be perpendicular to the horizontal guide rail 21. At this time, both the upper support beam 23 and the lower support beam 25 are attached to the wall surface, and at this time, the steel bar detector body 1 is lifted and attached to the wall surface. At this time, the support part 27 contacts the ground and obliquely supports on the surface of the lower support beam 25. At this time, the operator can control the steel bar detector body 1 to move horizontally along the horizontal guide rail 21 through the holding part 24 without deviation.
[0039] Refer to Figure 4 、 Figure 5 and Figure 6 As shown in
[0040] Refer to Figure 5, on any one of the ear seats on the same sliding seat 221, a first guide rod 224 is fixedly arranged. A limit disc 225 is fixedly arranged at one end of the first guide rod 224 away from the corresponding ear seat. A locking disc 226 is slidably arranged on the surface of the first guide rod 224. A first return spring 227 is sleeved on the surface of the first guide rod 224 between the limit disc 225 and the locking disc 226. On the side of the locking disc 226 close to the corresponding ear seat, four locking pins 228 evenly distributed along the circumferential direction of the locking disc 226 are fixedly arranged. The locking pins 228 movably penetrate through the corresponding ear seat and are movably inserted into the end face of the corresponding rotating shaft 222.
[0041] During specific operation, for the purpose of carrying and transporting the steel bar detector body 1, both the upper support beam 23 and the lower support beam 25 can rotate through their respective rotating shafts 222. By pulling the locking disc 226 outwards, the locking of the rotating shaft 222 by the locking pins 228 can be released. Then, after rotating the upper support beam 23 and the lower support beam 25 to a certain angle (0° or 90°), releasing the locking disc 226 can make the locking pins 228 be inserted into the end face of the rotating shaft 222 again to lock the rotating shaft 222. During subsequent carrying, the holding part 24 can be received into the upper support beam 23, and the supporting part 27 can be received into the lower support beam 25. At the same time, the upper support beam 23 and the lower support beam 25 rotate to be parallel to the transverse guide rail 21, reducing the overall size and facilitating transportation.
[0042] Refer to Figures 4 - 6 , in order to prevent the first sliding seat 221 from derailing, limit plates 7 penetrating through the upper and lower first chutes are slidably arranged on both the left and right sides of the transverse guide rail 21. Guide blocks 8 are fixedly arranged on the sides of the two left and right corresponding limit plates 7 away from each other. Second guide rods 9 are fixedly arranged in the second movable holes on both the left and right sides of the transverse guide rail 21. The second guide rods 9 are slidably connected with the guide blocks 8. A fifth return spring 10 is sleeved on the surface of the second guide rod 9 below the corresponding guide block 8. The upper and lower ends of the fifth return spring 10 are respectively fixedly connected with the lower side of the guide block 8 and the lower inner wall of the second movable hole. The limit plates 7 limit the edge of the first chute, thereby preventing the first sliding seat 221 from sliding out of the first chute.
[0043] Refer to Figure 5, in order to facilitate centering and locking the lower sliding seat 1-221 on the transverse guide rail 21 during use, a limiting groove 4 is provided on the upper inner wall of the lower chute 1, and a first movable hole is provided on the lower sliding seat 1-221. Movable grooves are provided on any two inner walls on the circumferential side of the first movable hole. The locking portion 26 includes a second return spring 261 fixedly arranged in the movable groove. The upper ends of the two second return springs 261 are fixedly provided with ear blocks 262. A locking block 263 is fixedly arranged between the two ear blocks 262. The locking block 263 is slidably arranged in the first movable hole. The upper end of the locking block 263 is movably inserted into the limiting groove 4. A cam block 264 is fixedly arranged at a position of the lower connecting block 223 close to the locking block 263. The cam block 264 is movably abutted against the lower side of the locking block 263.
[0044] During specific operation, slide the lower sliding seat 1-221 to the middle of the transverse guide rail 21, then pull the locking disc 226 to unlock the rotating shaft 222, and then rotate the lower support beam 25. When the lower support beam 25 rotates, drive the cam block 264 to rotate through the lower connecting block 223. The rotation of the cam block 264 can gradually abut against the lower side of the locking block 263 and push the locking block 263 upward, so that the locking block 263 is inserted into the limiting groove 4, and the sliding seat 1-221 is locked and no longer moves.
[0045] Refer to Figure 1 and Figure 3 , in order to reduce the difficulty for the staff to lift the reinforcing bar detector body 1 to a high position on the wall for operation, a first accommodating groove 251 is provided on the lower support beam 25. The supporting portion 27 includes a second sliding seat 271 slidably arranged in the first accommodating groove 251. An inclined support beam 272 is rotatably arranged on the second sliding seat 271. Spring locking pins 273 are arranged on the left and right sides of the second sliding seat 271. A plurality of jacks are provided on the left and right sides of the lower support beam 25 and are evenly distributed along its length direction. The spring locking pins 273 are movably inserted into the corresponding jacks.
[0046] During specific operation, the position of the second sliding seat 271 relative to the lower support beam 25 is adjusted by the spring locking pin 273. Specifically, the operator presses the end of the spring locking pin 273 with a finger or a tool to make it contract, unlocking the second sliding seat 271. After adjusting the second sliding seat 271 to the appropriate position, the spring locking pin 273 is reset and inserted into the corresponding jack for locking. Then, the inclined support beam 272 is rotated at a certain angle with the wall, so that the lower end of the inclined support beam 272 contacts the ground. At this time, the operator uses his foot to resist the lower end of the inclined support beam 272 to restrict the movement of the inclined support beam 272, and the inclined support beam 272 supports the whole. At the same time, the operator holds the transverse guide rail 21 with one hand and controls the holding part 24 with the other hand to control the steel bar detector body 1 to scan and drive the marking component 3 to make marks. When storing after use, the inclined support beam 272 can be completely stored in the first receiving groove 251 after rotation, which is convenient for subsequent carrying and transportation.
[0047] Refer to Figure 1 、 Figure 4 and Figure 7 As shown in
[0048] During specific operation, in order to reduce the difficulty of moving the steel bar detector body 1 driven by the upper support beam 23, the first sliding seat 221 moves in contact with the corresponding first chute through the guide balls 6, and the upper support beam 23 moves in contact with the wall through the guide rollers 5, greatly reducing the friction during movement. The operator can drive the upper support beam 23 to move horizontally by cooperating the holding rod 242 with the third sliding seat 241, and can also mark the wall by cooperating the third sliding seat 241 with the marking component 3. And when carrying, the holding rod 242 can be rotated and stored in the second receiving groove 231, which is convenient for carrying.
[0049] Refer to Figure 1 and Figure 7, the marking component 3 includes a third reset spring 31 fixedly arranged on the upper inner wall of the second receiving groove 231. The lower end of the third reset spring 31 is fixedly connected to a fourth sliding seat 32. A limiting strip 33 is fixedly arranged on the inner wall of the second receiving groove 231 near the fourth sliding seat 32. The limiting strip 33 is in movable contact with the fourth sliding seat 32. A second sliding groove is formed at the rear side of the fourth sliding seat 32. A slider 34 is slidably arranged in the second sliding groove. A marking pen 35 is fixedly arranged at the rear side of the slider 34. The marking pen 35 is detachable. A fourth reset spring 36 is sleeved on the surface of the marking pen 35. One end of the fourth reset spring 36 is fixedly connected to the side wall of the slider 34, and the other end of the fourth reset spring 36 is fixedly connected to the inner wall of the second sliding groove. A through hole communicating with the second sliding groove is formed at the lower side of the fourth sliding seat 32. The front side of the slider 34 is provided with a slope surface. The upper end of the matching block 11 movably penetrates through the through hole and is in movable contact with the slope surface of the slider 34. The limiting strip 33 makes the third reset spring 31 in a compressed state under normal conditions, so that the matching block 11 will not move the fourth sliding seat 32 when passing through the through hole.
[0050] During specific operation, in order to facilitate the marking work after the steel bar scanning at a high position on the wall, when the steel bar scanner body scans the position of the steel bar, the staff controls the fourth sliding seat 241 to move upward through the holding rod 242, so as to drive the matching block 11 to move upward and insert into the through hole on the surface of the fourth sliding seat 32 and be in contact with the slope surface of the slider 34. The matching block 11 drives the slider 34 to move backward, so that the slider 34 can drive the marking pen 35 to move towards the wall surface and be in contact with the wall surface. Then the fourth sliding seat 241 can drive the fourth sliding seat 32 to move upward along the second receiving groove 231, so that the marking pen 35 can leave a vertical line marking the position of the steel bar at the corresponding position on the wall.
[0051] In addition, this solution also provides a method for using a concrete steel bar detector based on phased array ultrasonic waves, which is implemented by the above-mentioned concrete steel bar detector based on phased array ultrasonic waves, and includes the following steps:
[0052] S1. Assembly: Unfold the originally folded auxiliary fixing frame 2, and rotate and adjust the lower support beam 25 and the upper support beam 23 to be perpendicular to the transverse guide rail 21.
[0053] S2. Placement: Center the transverse guide rail 21, the upper support beam 23 and the upper support beam 23 on the surface of the wall to be scanned, so that the lower end of the diagonal support beam 272 contacts the ground. Then the staff touches the lower end of the diagonal support beam 272 with their feet and holds the transverse guide rail 21 with their hands.
[0054] S3. Scanning: The staff controls the upper support beam 23 to slide through the holding rod 242 and the fourth sliding seat 241 to drive the steel bar detector body 1 to slide horizontally for scanning.
[0055] S4. Mark. After determining the scanning position, the operator presses the horizontal guide rail 21 and the upper sliding seat 221 with hands at the same time, and then uses the other hand to push the third sliding seat 241 upward through the holding rod 242. The mating block 11 on the third sliding seat 241 abuts against the slider 34 in the fourth sliding seat 32, controlling the marking pen 35 to extend out of the second chute and contact the wall surface. The fourth sliding seat 32 can slide upward to drive the marking pen 35 to leave a vertical line mark on the wall surface. By repeating this process, the scanning of a single wall can be completed.
