Description

Technical Field

[0001] The present application relates to the field of core sample scanning and detection equipment, and in particular to a core sample outer surface analysis scanning device and a scanning method. Background Art

[0002] During the construction process, scanning and analysis of the outer surface of concrete core samples is an important part of construction quality control. The scanning results can be used to determine whether the construction processes such as concrete pouring and vibration meet the requirements of the specifications, so as to adjust the construction plan in time to ensure construction quality.

[0003] For problems found by scanning, such as concrete segregation and insufficient vibration, corrective measures can be taken in time to avoid the problem from expanding and affecting the overall project quality. Similarly, scanning analysis data can also be used for the research and development of concrete materials. By scanning and analyzing concrete core samples with different mix ratios and different curing conditions, we can deeply understand the performance change law of concrete and provide data support for the research and development of new materials.

[0004] At present, the analysis and scanning of the outer surface of the core sample requires rotating the core sample and analyzing the entire outer surface of the core sample through a scanning device. However, since the mass of the core sample is usually large, when the core sample is manually rotated for scanning, the rotation speed of the rotating core sample will be out of sync, resulting in differences in the detection time of different parts of the outer surface, which affects the analysis and scanning effect.

[0034] An embodiment of the present application discloses a core sample outer surface analysis scanning device.

[0035] like Figure 1 As shown, the core sample outer surface analysis scanning device includes a support frame 1, a moving part 2, a scanner 3, a support plate 4, a limiting plate 11 and an angle adjustment device 5. The support plate 4 is mounted on the support frame 1. The support plate 4 is preferably made of a transparent plate with a certain structural wall such as an acrylic plate. The moving part 2 is mounted on the support frame 1 and is located below the support plate 4. The scanner 3 is mounted on the moving part 2. The scanner 3 can be a common handheld scanner 3 on the market, or other common scanners 3. The scanner 3 can be driven by the moving part 2 to move along the support plate 4. The angle adjustment device 5 is provided on the moving frame 21. The limiting plate 11 is hinged with the moving part 2 through the angle adjustment device 5. The core sample is placed on the support plate 4, so that the core sample can be pushed to move by the limiting plate 11, and then the outer surface of the core sample is analyzed and scanned by the scanner 3.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the movable member 2 includes a movable frame 21, a limit rack 22, a driving motor 23, a driving gear 24, a limit rod 25 and an auxiliary gear 26. The limit rack 22 and the limit rod 25 are respectively installed on both sides of the support frame 1.

[0037] The movement of the mobile frame 21 is controlled by driving the motor 23 to avoid manual driving of the mobile frame 21. During the scanning and analysis process of the scanner 3, the speed of the mobile frame 21 is inconsistent, causing the core sample to be affected by inertia and inconsistent with the moving speed of the scanner 3, thereby affecting the analysis and scanning effect of the scanner 3 on the core sample.

[0038] like Figure 5As shown, the angle adjustment device 5 includes an adjustment plate 51, an adjustment motor 52, a first adjustment block 53, a second adjustment block 54 and an adjustment screw 55. Support rods are arranged on both sides of the mobile frame 21. The support rods extend to the top of the support plate 4 away from one end of the mobile frame 21. A rotating shaft is arranged between the two support rods. The limiting plate 11 is rotatably connected to the rotating shaft. The adjustment plate 51 is fixedly connected to the support rods on one side. The adjustment plate 51 is preferably set as a circular plate. The first adjustment block 53 is rotatably connected to the adjustment plate 51. The adjustment motor 52 is installed on the first adjustment block 53. One end of the adjusting screw 55 is fixedly connected to the output shaft of the adjusting motor 52, and the second adjusting block 54 is rotatably connected to the side wall of the limiting plate 11. The other end of the adjusting screw 55 passes through the second adjusting block 54 and is drivingly connected to the second adjusting block 54. A scale line 511 is provided on the edge of the adjusting plate 51, and a scale pointer 111 is provided on the side wall of the limiting plate 11 corresponding to the scale line 511, and the scale pointer 111 points to the scale line 511, so that the rotation angle of the limiting plate 11 can be observed and the limiting plate 11 can be adjusted to a suitable position.

[0039] The adjusting plate 51 is fixedly connected to the movable part 2, the first adjusting block 53 is rotatably connected to the adjusting plate 51, the adjusting motor 52 is fixedly connected to the first adjusting block 53, the adjusting screw 55 is fixedly connected to the output shaft of the adjusting motor 52, the second adjusting block 54 is rotatably connected to the limiting plate 11, and the adjusting screw 55 is drivingly connected to the second adjusting block 54, so that the adjusting screw 55 can be driven to rotate by the adjusting motor 52, and the limiting plate 11 can be driven to rotate, so as to adjust the angle between the limiting plate 11 and the support plate 4 to adapt to core samples of different sizes, and at the same time, the stability of the limiting plate 11 can be ensured when the limiting plate 11 does not need to be adjusted, thereby preventing the limiting plate 11 from rotating relative to the support plate 4.

[0040] like Figure 6 As shown, in the embodiment of the present application, it also includes a limit roller 6, a limit seat 7, a limit motor 8, a limit screw 9 and a synchronous drive device 10. The limit plate 11 is provided with a limit plate 11 slot, and the limit seat 7 is provided with a slider corresponding to the limit plate 11 slot. The slider is slidably connected in the limit plate 11 slot, the limit roller 6 is rotatably connected to the limit seat 7, the limit motor 8 is installed on the limit plate 11 away from the end connected to the rotating shaft, the limit screw 9 is fixedly connected to the output shaft of the limit motor 8, the limit screw 9 is arranged in the limit plate 11 slot, and is drivingly connected to the slider.

[0041] The limit seat 7 is installed on the limit plate 11, and the limit roller 6 is rotatably connected to the limit seat 7. The limit roller 6 abuts against the core sample, so that the core sample is pushed to roll through the limit roller 6, thereby changing the sliding friction between the limit plate 11 and the core sample to the rolling friction between the limit roller 6 and the core sample, reducing the possibility of the core sample sliding relative to the support plate 4 due to the influence of friction, making the rolling of the core sample smoother, so as to ensure the scanning and detection effect of the core sample.

[0042] The synchronous drive device 10 includes a driving roller 101, a first synchronous wheel 102, a second synchronous wheel 103, a third synchronous wheel 104 and a synchronous belt 105. The driving roller 101 is rotatably connected to the rotating shaft. The driving roller 101 and the support plate 4 are supported and pressed against each other. As the moving frame 21 moves, the driving roller 101 rotates relatively, and the rotational linear speed of the driving roller 101 is consistent with the horizontal speed of the moving frame 21. The driving roller 101 and the limiting roller 6 are located in the same horizontal plane in the vertical direction. The first synchronous wheel 102 is rotatably connected to the rotating shaft and is connected to the limiting roller 6. Thus, the first synchronous wheel 102 can be driven to rotate by the rotation of the driving roller 101, the second synchronous wheel 103 is rotatably connected to the end of the limiting plate 11 away from the rotating shaft, the third synchronous wheel 104 is connected to the limiting roller 6, and the synchronous belt 105 is jointly mounted on the first synchronous wheel 102, the second synchronous wheel 103 and the third synchronous wheel 104. The first synchronous wheel 102, the second synchronous wheel 103 and the third synchronous wheel 104 are in the same horizontal plane in the vertical direction, so that when the third synchronous wheel 104 moves relative to the limiting plate 11 along with the limiting roller 6, the synchronous belt 105 is always in a taut state.

[0043] The driving roller 101 is installed on the limiting plate 11, the driving roller 101 is connected to the roller of the support plate 4, the first synchronous wheel 102 is coaxially connected to the driving roller 101, the second synchronous wheel 103 is installed at the end of the limiting plate 11 away from the driving roller 101, the third synchronous wheel 104 is connected to the limiting roller 6, the first synchronous wheel 102, the second synchronous wheel 103 and the third synchronous wheel 104 are jointly sleeved with a synchronous belt 105, so as to ensure that the linear speed of the limiting roller 6 and the moving frame 21 is consistent, thereby further ensuring the consistency of the moving speed between the core sample and the moving frame 21, so that the limiting roller 6 and the core sample are always in a rolling friction state, further ensuring the rolling smoothness of the core sample.

[0044] The implementation principle of the core sample outer surface analysis scanning device of the embodiment of the present application is as follows: according to the size of the core sample to be analyzed and scanned, the adjusting motor 52 is used to drive the adjusting screw 55 to rotate, because the first adjusting block 53 is rotatably connected to the adjusting plate 51, the second adjusting plate 51 is rotatably connected to the limiting plate 11, and the adjusting screw 55 is drivingly connected to the second adjusting plate 51, thereby driving the limiting plate 11 to rotate to a suitable angle, and then the limiting screw 9 is driven to rotate by the limiting motor 8, because the limiting screw 9 is drivingly connected to the slider, so that the slider slides in the slide groove of the limiting plate 11, and the limiting roller 6 is adjusted to a suitable height through the limiting seat 7; The driving motor 23 is started, and the driving motor 23 drives the driving gear 24 to rotate. The driving gear 24 cooperates with the driving gear 24 to drive the moving frame 21 to move. The moving frame 21 ensures stability during movement under the action of the auxiliary gear 26 and the limit rod 25. The moving frame 21 drives the limiting plate 11 to move, and the driving roller 101 is connected to the rotating shaft. The driving roller 101 rotates with the movement of the moving frame 21. The driving roller 101 drives the first synchronous wheel 102. The first synchronous wheel 102 drives the third synchronous wheel 104 to rotate under the action of the synchronous belt 105, thereby ensuring that the linear speed between the limit roller 6 and the driving roller 101 is consistent with the horizontal moving speed of the moving frame 21, and then the core sample is pushed to rotate through the limit roller 6. The limit roller 6 and the core sample are always in a rolling friction state, which ensures the rolling smoothness of the core sample, thereby improving the effect of analyzing and scanning the outer surface of the core sample.

Since the first adjusting block 53 is rotatably connected to the adjusting plate 51, the second adjusting plate 51 is rotatably connected to the limiting plate 11, and the adjusting screw 55 is drivingly connected to the second adjusting plate 51, the limiting plate 11 is driven to rotate to a suitable angle.

[0046] S20: According to different core sample sizes, the limiting roller 6 is adjusted to a suitable height; The limit motor 8 drives the limit screw 9 to rotate. Since the limit screw 9 is connected to the slider, the slider slides in the slide groove of the limit plate 11, and the limit roller 6 is adjusted to a suitable height through the limit seat 7.
