Description

[0002] Concrete surface quality testing is an inspection that detects cracks that extend from the concrete surface into the interior of concrete building structures.

[0024] In the embodiment of the present disclosure, there are two groups of sliding frames 20, and the sliding frames 20 are symmetrically distributed on the left and right. The central part of each group of sliding frames 20 is provided with a through hole that passes through it on the left and right. The guide rod 22 is inserted into the central through hole of the sliding frame 20, so that the sliding frame 20 uses the through hole to support the mounting seat 25 welded to the guide rod 22 to move in a directional manner left and right, so that the ultrasonic plane transducer 23 can always fit the uneven concrete wall and move stably under the push of the spring 24.

In the process of the displacement detection motor 12 driving the transmission rod 13 to rotate, the transmission rod 13 drives the two groups of reversing sleeves 14 on the outer side to rotate synchronously through the convex strip, so that the two groups of reversing sleeves 14 respectively drive the transverse threaded rods 16 welded to the two groups of bevel gears 15 to rotate synchronously, thereby realizing the synchronous movement detection work of the two groups of ultrasonic planar transducers 23 relative to each other on both sides of the square wall column.
[0026] In the embodiment of the present disclosure, there are two groups of sliding frames 20, and the sliding frames 20 are symmetrically distributed on the left and right sides. The left side surface near the top of each group of sliding frames 20 is provided with left and right through-threaded through holes. The left side surface near the top of the sliding frame 20 is provided with a through hole. The reversing sleeve 14 is rotatably connected to the through hole of the sliding frame 20. The positive threaded end of the outer side surface of the bidirectional threaded rod 11 is engaged and connected to the threaded through hole of the left sliding frame 20, and the reverse threaded end of the outer side surface of the bidirectional threaded rod 11 is engaged and connected to the threaded through hole of the right sliding frame 20. The bidirectional threaded rod 11 drives the two groups of sliding frames 20 to move left and right along the transmission rod 13 inserted into the inside of the reversing sleeve 14, so that the sliding frame 20 drives the ultrasonic plane transducer 23 to detect the surfaces of concrete wall columns of different widths.
[0027] In the disclosed embodiment, there are four groups of universal casters 4, which are respectively connected to the four corners of the lower side of the frame 3 by bolts. The frame 3 can be moved arbitrarily inside the construction site through the universal casters 4, making it convenient for inspection personnel to move the ultrasonic detector 6 installed on the frame 3 through the handrail 5 to inspect multiple groups of square wall columns in the construction site.
[0028] In the disclosed embodiment, the support frame 9 is a rectangular frame structure that passes through from front to back. The rear side of the support frame 9 is attached to the front side of the vertical frame 1. A protrusion is provided at the center position of the rear side of the frame structure of the support frame 9. The upper side of the protrusion is provided with a threaded through hole that passes through from top to bottom. The outer side of the vertical threaded rod 2 is threadedly engaged with the threaded through hole of the protrusion of the support frame 9. The lifting motor 19 drives the support frame 9 to move vertically along the vertical frame 1 through the vertical threaded rod 2, so that the ultrasonic plane transducer 23 can perform detection work on the wall surfaces at different heights on the concrete wall column.
[0029] The specific usage and function of this embodiment are as follows:
[0030] When the utility model is carrying out the wall surface quality inspection of concrete wall columns, the inspection personnel push the handrail rod 5 to move the frame 3 to the front side of the building wall column. At this time, the two groups of ultrasonic plane transducers 23 are respectively located on the left and right sides of the building wall column. Then the handrail turntable 10 is manually rotated, and the handrail turntable 10 drives the bidirectional threaded rod 11 to rotate. Since the threaded through holes of the two groups of sliding frames 20 are respectively engaged with the forward threaded end and the reverse threaded end of the bidirectional threaded rod 11, the bidirectional threaded rod 11 drives the two groups of sliding frames 20 to move left and right along the transmission rod 13 until the two groups of ultrasonic plane transducers 23 are respectively attached to the left and right sides of the building wall column. Then the controller 7 controls the displacement detection motor 12 to drive the transmission rod 13 to rotate. Since the convex strips on the outer side of the transmission rod 13 are embedded in the inner side grooves of the cylinder of the reversing sleeve 14, the transmission rod 13 drives the two groups of reversing sleeves 14 to rotate. Due to the helical tooth structure on the outer side of the reversing sleeve 14 and the bevel gear structure, the two groups of The wheels 15 are meshed with each other, and the two sets of reversing sleeves 14 respectively drive the two sets of transverse threaded rods 16 welded to the bevel gears 15 to rotate, and the two sets of transverse threaded rods 16 respectively drive the two sets of displacement plates 21 to move synchronously back and forth along the guide support rods 18. At this time, the ultrasonic plane transducers 23 on both sides of the wall column are in contact with the wall surface and synchronously move with the two sets of displacement plates 21 for detection. The ultrasonic detector 6 controls one set of ultrasonic plane transducers 23 to emit ultrasonic waves, and the ultrasonic waves pass through the concrete wall column. The other set of ultrasonic plane transducers 23 receives the emitted ultrasonic signals and transmits the ultrasonic signals passing through the wall column to the ultrasonic detector 6 through the wire for analysis. If the detection height of the wall column needs to be changed, the controller 7 controls the lifting motor 19 to drive the vertical threaded rod 2 to rotate, and the vertical threaded rod 2 drives the support frame 9 meshed with the outer side to move up and down in contact with the front side of the vertical frame 1, thereby completing the lifting and lowering adjustment work of changing the detection height of the wall column.
[0031] All of the above components are installed, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve a beneficial effect may be implemented. The ultrasonic detector 6, controller 7, lift motor 19, and ultrasonic planar transducer 23 used are all commonly available components on the market. Upon purchase, they can be connected and used simply by following the included instruction manual, so further details will not be provided here.
