Description
Technical Field
[0001] This utility model relates to the field of concrete core measurement technology, and in particular to a scanning device for measuring the size of concrete core samples. Background Technology
[0002] Currently, the processing and measurement of concrete core samples typically involves first measuring the core sample diameter, then cutting the concrete core sample using a core sample cutting machine to a specific length-to-diameter ratio, followed by grinding or leveling the end faces of the cut concrete core sample. Before testing, the average diameter, height, perpendicularity, and flatness of the core sample specimen are measured. This entire core sample processing and measurement process requires highly experienced operators, has low automation, is complex, time-consuming, suffers from low cutting machine precision, and exhibits unstable core sample dimensional deviations. Furthermore, it is highly susceptible to core sample failure due to operator error. Utility Model Content

If the specific posture changes, the directional indicator will also change accordingly.
[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] like Figure 1-4 As shown, a scanning device for measuring the size of concrete core samples includes a main body 1 and a protective cover 2. The protective cover 2 is movably installed on the upper end of the main body 1. A first motor 3 is fixedly installed on one side surface of the main body 1. A second motor 4 is fixedly installed on the front surface of the main body 1 near the upper center. A servo moving frame 5 is installed inside the main body 1. A laser cutting mechanism 6 is movably installed on the servo moving frame 5. An electric telescopic rod 7 is fixedly installed above the front end of the laser cutting mechanism 6. A laser scanner 8 is fixedly installed at the telescopic end of the electric telescopic rod 7. An adjusting seat 9 is movably installed on the lower inner surface of the main body 1 near both sides. A support block 10 is movably installed on the lower inner surface of the main body 1 at the front end of the adjusting seat 9. A control panel 11 is provided on the upper surface of the main body 1 at the front side. A sliding seat 12 is movably installed on the lower inner surface of the main body 1 at the center. A dual-axis motor 13 is fixedly installed inside the sliding seat 12. A grinding wheel 14 is fixedly installed at the output end of the dual-axis motor 13.
[0021] In the above structure, when the concrete core is placed inside the main body 1 of the device for cutting and grinding, the coordination and movement sequence of motor 3, motor 4, motor 901, servo moving frame 5, laser cutting mechanism 6 and laser scanner 8 are all operated in an orderly manner through program settings. The actions of motor 3, motor 4, motor 901, servo moving frame 5, laser cutting mechanism 6 and laser scanner 8 can also be manually controlled through the operation of control panel 11.
[0022] In a preferred embodiment: a first moving groove 101 is provided on the inner lower surface of the device body 1 near both sides, a second moving groove 103 is provided on the inner lower surface of the device body 1 in the middle, a rod groove 104 is provided on the inner lower surface of the device body 1 at one end of the first moving groove 101, and dustproof folding covers 102 are installed at both ends of the first moving groove 101 and the second moving groove 103.
[0023] In the above structure, the dustproof folding cover 102 is fixedly installed inside the first moving slot 101 and the second moving slot 103. One end of the dustproof folding cover 102 is fixed to the threaded sleeve block. Therefore, the dustproof folding cover 102 has a certain dustproof shielding effect on the first moving slot 101 and the second moving slot 103, preventing the debris during the cutting and grinding process from entering the first moving slot 101 and the second moving slot 103. When the threaded sleeve block moves, the dustproof folding cover 102 will fold and extend.
[0024] In a preferred embodiment: a No. 3 motor 901 is fixedly installed on one end surface of the adjusting seat 9, and a double-ended threaded rod 902 extending inside the adjusting seat 9 is fixedly installed at the output end of the No. 3 motor 901. An arc-shaped clamping plate 903 is threaded on the surface of the double-ended threaded rod 902 and close to both ends.
[0025] In the above structure, when the No. 3 motor 901 starts operating in both directions, the No. 3 motor 901 controls the double-headed threaded rod 902 to rotate in both directions. The rotating double-headed threaded rod 902 will cause the arc-shaped clamping plates 903 with threads on them to move closer and further apart. When the arc-shaped clamping plates 903 move closer together, they can clamp and fix the concrete core that needs to be cut.
[0026] In a preferred embodiment: the output end of motor 3 is fixedly installed with a double-threaded shaft extending inside the device body 1, the output end of motor 4 is fixedly installed with a threaded rod extending inside the device body 1 and located below the double-threaded shaft, and threaded sleeve blocks are fixedly installed on the lower surfaces of adjusting seat 9 and sliding seat 12. The threaded sleeve block of adjusting seat 9 is sleeved on the double-threaded shaft, and the threaded sleeve block of sliding seat 12 is sleeved on the threaded rod.
[0027] In the above structure, when the first motor 3 operates in both directions, it drives the double-headed threaded shaft to rotate in both directions. The rotating double-headed threaded shaft causes the adjusting seats 9, which are threaded on it, to move closer and further apart. This controls the distance between the two adjusting seats 9, thereby clamping and fixing the two ends of the concrete core of different lengths during cutting. Similarly, when the second motor 4 starts in both directions, it can move the sliding seat 12, which is threaded on the threaded rod. When the sliding seat 12 approaches the cutting surface of the concrete core, by starting the dual-axis motor 13, the grinding wheel 14 can be rotated and the cutting section of the concrete core can be ground.
[0028] In a preferred embodiment: one end of the dustproof folding cover 102 is fixed to the threaded sleeve block, a guide rod 1001 extending into the rod groove 104 is fixedly installed on the lower surface of the support block 10, a stop block 1002 is fixedly installed on the surface of the guide rod 1001, a spring 1003 is sleeved on the surface of the guide rod 1001 located inside the rod groove 104, the upper end of the spring 1003 is fixed to the inner upper surface of the rod groove 104, and the lower end of the spring 1003 is fixed to the stop block 1002.
[0029] In the above structure, the spring 1003 is in a compressed state under natural conditions. When a concrete core is placed on the support block 10, the support block 10 will be pressed down. When the support block 10 descends, since the upper end of the spring 1003 is fixed to the inner upper surface of the rod groove 104 and the lower end of the spring 1003 is fixed to the stop block 1002, the spring 1003 will be stretched and unfolded due to the descent of the stop block 1002. This allows the support block 10 to adapt to concrete cores of different diameters and lift them, thus preventing the cut concrete core from tilting downwards due to one end being heavier.
[0030] In use, the uncut concrete core is placed on two support blocks 10, with both ends of the concrete core positioned between the two arc-shaped clamps 903 of the adjusting frame 9. Then, the first motor 3 is activated via the control panel 11, controlling the rotation of the double-headed threaded shaft. This causes the two adjusting seats 9 to move closer together until both ends of the concrete core are clamped by the adjusting seats 9. At this point, the protective cover 2 is closed, and the third motor 901 is activated. The third motor 901 drives the double-headed threaded rod 902 to rotate. The rotating double-headed threaded rod 902 causes the two arc-shaped clamps 903 to move closer together until the concrete core is clamped in the middle position of the two arc-shaped clamps 903. At this point, under program control, the main body 1 moves the servo moving frame 5 to the position of the concrete core, and the laser cutting mechanism 6 moves behind the concrete core. The laser scanner 8 is then used to cut the concrete core. The length of the core is scanned and measured, and the scanned data is then imported into the system of the control panel 11. The required dimensions are then manually set and the required dimensions are cut. After the cutting is completed, the adjusting seat 9 moves the clamped and cut concrete cores away from each other, and keeps one part of the support block 10 supporting the concrete core, while the other part of the support block extends beyond the cut surface of the concrete core. Then, the electric telescopic rod 7 controls the lower end of the laser scanner 8 to contact the concrete core and scan the cut surface. The laser is reflected back by the support block 10 to measure the diameter and flatness of the cut surface. Then, the second motor 4 controls the sliding seat 12 to move towards the cut surface, and the dual-axis motor 13 drives the grinding wheel 14 to rotate and grind the cut surface. After grinding, the flatness is measured again by the laser scanner 8. This cycle is repeated until the cut surface is flat. After processing, the dust inside the device is cleaned.
