Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a laser detection device for the flatness of the installation surface of prefabricated components. Background Technology

[0002] Precast concrete components (PC) are the foundation for precasting the main structure. The equipment used to produce precast components directly determines the cost and quality of precast concrete components. In the field of residential industrialization, they are called PC components, such as precast reinforced concrete column foundations, precast steel structure column foundations, reinforced concrete foundations for street light and billboard columns, and precast floor slabs.

[0003] Chinese patent CN116429030B discloses a device for detecting the flatness of precast concrete (PC) components, relating to the field of precast building technology. It addresses the problems of scattered data collection, large detection errors, heavy weight, cumbersome movement, and inability to detect the flatness of cut surfaces on both sides of PC components. This invention includes a detection platform and a displacement slide plate positioned above the platform. The top of the detection platform is connected to the outer surface of the displacement slide plate via a support frame, and a displacement sliding block is slidably connected to the inner surface of the displacement slide plate. The invention utilizes a first detection roller for rolling detection of the top of the PC component, providing a more comprehensive inspection and increasing the device's accuracy. A motor enables automatic movement of the first detection roller, simplifying operation and saving labor. A threaded rod allows adjustment of the roller's height, enabling the device to detect PC components of varying thicknesses, increasing its applicability. However, existing surface flatness detection devices for precast components typically employ fixed gantry frames or tabletop scanning structures, only capable of laser scanning the top and side facades of the component. For precast components that are heavy (often several tons) and large in volume (such as square columns, equipment foundation blocks, double T-slabs, etc.), the bottom surface (i.e. the critical installation surface) in contact with the formwork cannot be directly observed because it is difficult to flip or hoist and adjust its posture. Especially for support column components with installation surfaces on all four sides, the lack of flatness data on any side will directly cause major quality hazards such as insecure support, eccentric stress, and loose joints during subsequent on-site installation. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a laser detection device for the flatness of the mounting surface of prefabricated components.

The first frame is mounted on both the left and right sides of the second frame. Sliding frames are slidably mounted on the four vertical frames of the second frame, and cylinders are installed inside the four vertical frames. The extension rods of the cylinders are connected to the bottom of the sliding frames.

The first frame on the right is equipped with a first scanning component that can slide and scan towards the second frame. The second frame is equipped with an auxiliary support component that can support the precast components being transported. The bottom of the first frame on the right is equipped with a second scanning component that can slide and scan towards the second frame. The second scanning component is used to perform swing scanning on the bottom mounting surface of the precast components. The first scanning component is equipped with a swing component. The first scanning component moves to perform swing scanning on the top and front and rear mounting surfaces of the precast components.

[0011] In one embodiment, the system further includes a laser emitter and a laser receiver, with the laser emitter located on the left side of the mounting bracket at the rear of the second rack and the laser receiver located on the left side of the mounting bracket at the front of the second rack.

[0012] In one embodiment, a support frame is also included. The support frame is mounted on the vertical frame of the first frame and is flush with the first sliding frame, for supporting the first rack that has moved to the left.

[0013] In one embodiment, the system also includes a control panel with a built-in controller. The controller is connected via wiring to a cylinder, an electric conveyor roller, a first motor, a first scanner, a second scanner, a second motor, a third scanner, a third motor, a camera recognition component, a laser emitter, and a laser receiver.

[0014] Beneficial effects: 1. This invention achieves multi-dimensional oscillating laser scanning of the top, front and rear mounting surfaces, and bottom of a component by coordinating the movement of the first and second scanning components and cooperating with the oscillating component to drive the scanner to oscillate back and forth around the axis. This effectively covers irregular surfaces and hidden areas, avoiding the detection blind spots caused by fixed scanning. Simultaneously, when the second rack moves to the left, it meshes with the third gear and is driven by the third motor to maintain a constant speed. The third scanner remains in a stable motion state throughout the bottom surface scanning process, significantly improving the continuity and data integrity of complex surface flatness detection.

[0015] 2. This invention employs an auxiliary support component, using a magnetically levitated conical top block to provide multi-point flexible support for the component. Combined with elastic elements and folding sleeves for buffering and vibration absorption, this effectively isolates low-frequency vibrations caused by equipment operation and the external environment. Furthermore, a camera and recognition component captures recognition light points on the conical top block in real time. The controller determines the component's tilt state based on the spatial coordinates of each light point and dynamically adjusts the magnetic levitation height, ensuring the component maintains a relatively horizontal reference throughout the detection process. This eliminates the systematic errors introduced by unevenness in the support system itself, significantly improving the accuracy and repeatability of laser scanning data.

[0030] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the second scanning assembly 8 includes a connecting block 81, a second sliding frame 82, a second rack 83, a mounting block 84, a second motor 85, a second gear 86, a second crossbeam 87, a third rotating shaft 88, a third scanner 89, a first circular frame 810, a fourth rotating shaft 811, a first pulley 812, a first flat belt 813, a first sliding block 814, a first circular plate 815, a first sliding shaft 816, a sliding sleeve 817, an L-shaped block 818, a third motor 819, and a third gear 8110. Connecting blocks 81 are provided on the adjacent side walls of the vertical frame of the first frame 1 on the right side.

A first loop frame 810 is arranged at both the front and rear ends of the third rotating shaft 88. The first loop frame 810 is located at the second... Within the rectangular groove of the second rack 83, a fourth rotating shaft 811 is rotatably mounted at both ends of the second rack 83. A first circular plate 815 is mounted at the end of the fourth rotating shaft 811 closest to the first ring frame 810. A first sliding shaft 816 is eccentrically mounted on the first circular plate 815, and the first sliding shaft 816 slides in conjunction with a slotted groove of the adjacent first ring frame 810. A first pulley 812 is mounted at the end of the fourth rotating shaft 811 furthest from the first ring frame 810. A first flat belt 813 is wound between the two first pulleys 812 on the same side. A first sliding block 814 is located at the lower part of the first flat belt 813. A slotted groove is formed at the bottom of the rectangular grooves of the two second racks 83 that are far apart from each other. A sliding block 814 passes through a slot and contacts the bottom of the second sliding frame 82. A sliding sleeve 817 with the same height as the second sliding frame 82 is provided on the side wall of the rectangular housing 71. The sliding sleeve 817 is used to guide and support the second rack 83 that slides to the left. An L-shaped block 818 is provided on the rectangular housing 71. A third motor 819 is provided on the L-shaped block 818. A third gear 8110 is provided on the output shaft of the third motor 819. The third gear 8110 meshes with the second rack 83. When the second rack 83 moves to the left and meshes with the third gear 8110, the third motor 819 drives the third gear 8110 to rotate, so that the second gear 86 moves forward steadily and at a constant speed.

[0031] like Figure 3 and Figure 7As shown, the swing assembly 9 includes a fifth rotating shaft 91, a first bevel gear 92, a second ring frame 93, a sixth rotating shaft 94, a seventh rotating shaft 95, a second bevel gear 96, a second circular plate 97, a second sliding shaft 98, a second pulley 99, a second flat belt 910, and a second sliding block 911. The second rotating shaft 910 has first bevel gears 92 at both its front and rear ends. The fifth rotating shaft 91 is rotatably mounted at the bottom of the upper mounting box 65, with first bevel gears 92 at the top of each shaft. Two adjacent bevel gears mesh. The first rotating shaft 98 has second ring frames 93 at both its upper and lower ends. The sixth rotating shaft 94 is rotatably mounted at the bottom of the lower mounting box 65, with adjacent sixth rotating shafts 94 coinciding with the central axis of the fifth rotating shaft 91. The first rack 62 has rectangular slots on both its front and rear sidewalls. A seventh rotating shaft 95 is rotatably provided on both sides of the rack 62. A second bevel gear 96 is provided at the end of the first rotating shaft 68 and the sixth rotating shaft 94, and the second bevel gears 96 mesh with each other. A second circular plate 97 is provided at the end of the sixth rotating shaft 94 and the fifth rotating shaft 91 that are close to each other. A second sliding shaft 98 is eccentrically provided on the second circular plate 97. The second sliding shaft 98 slides in a slot with the adjacent second ring frame 93. A second pulley 99 is provided at the end of the seventh rotating shaft 95 that is away from the second bevel gear 96. A second flat belt 910 is wound between the two second pulleys 99 on the same first rack 62. A second sliding block 911 is provided on the left side of the bottom of the second flat belt 910. A slot is opened at the bottom of the rectangular groove of the first rack 62, and the second sliding block 911 passes through the slot.

[0032] like Figure 1 and Figure 9 As shown, it also includes a horizontal plate 10, a shooting recognition component 11, and a recognition light spot 12. The mounting bracket 4 on the second frame 2 is provided with a horizontal plate 10. The shooting recognition component 11 is installed on the horizontal plate 10 at intervals. The cone-shaped top block 75 is provided with a recognition light spot 12, which corresponds one-to-one with the adjacent shooting recognition component 11.

[0033] like Figure 1 As shown, it also includes a laser emitter 13 and a laser receiver 14. The laser emitter 13 is located on the left side of the mounting bracket 4 on the rear side of the second frame 2, and the laser receiver 14 is located on the left side of the mounting bracket 4 on the front side of the second frame 2. It also includes a support frame 15 and a control panel 16. The support frame 15 is provided on the vertical frame of the first frame 1. The support frame 15 is flush with the first sliding frame 61 and is used to support the first rack 62 that has moved to the left side. The control panel 16 has a built-in controller. The controller is connected to the cylinder 31, the electric conveyor roller 5, the first motor 63, the first scanner 69, the second scanner 611, the second motor 85, the third scanner 89, the third motor 819, the image recognition component 11, the laser emitter 13, and the laser receiver 14 via wiring.

[0034] When this device is needed, the prefabricated component is transported to the second frame 2 area by the electric conveyor roller 5 on the right. When the beam between the laser emitter 13 and the laser receiver 14 is blocked by the component, the electric conveyor roller 5 is stopped. At the same time, the controller controls the four cylinders 31 to retract synchronously, which drives the sliding frame 3 and the spaced electric conveyor roller 5 to move down as a whole, so that the component gradually descends and is supported by the auxiliary support assembly 7. In this assembly, the conical top block 75 forms a magnetic levitation support through the strong magnetic repulsion between the second magnet 76 and the first magnet 74 in the cylindrical tube 73. At the same time, the folding sleeve 78 and the elastic element 77 provide flexible buffering, realizing multi-point suspension support for the component and effectively isolating mechanical vibration.

[0035] Subsequently, the controller drives the first motor 63 to operate, which in turn drives the first gear 64 to rotate. The first gear 64 meshes with the first rack 62, causing the vertical frame 66 and the first horizontal frame 67 to move synchronously to the left along the first sliding frame 61. Because the second sliding block 911 is in contact with and restrained by the left side of the first sliding frame 61, when the first gear 64 moves to the left, the second pulley 99 moves to the right, thereby driving the second pulley 99 to rotate. The second pulley 99 drives the seventh rotating shaft 95 to rotate, and the seventh rotating shaft 95 passes through the first... The second bevel gear 96 drives the sixth rotating shaft 94 to rotate, the sixth rotating shaft 94 drives the second circular plate 97 and the second sliding shaft 98 to rotate, the second sliding shaft 98 drives the second rotating frame 93 to swing back and forth, which in turn drives the first rotating shaft 68 to swing back and forth, the first rotating shaft 68 drives the first scanner 69 to swing back and forth, the first rotating shaft 68 drives the second rotating shaft 610 and the second scanner 611 to swing back and forth through the first bevel gear 92, the first scanner 69 and the second scanner 611 generate swing scanning during transverse movement to adapt to irregular surfaces.

[0036] Meanwhile, the controller drives the second motor 85 to work, and the second motor 85 drives the second gear 86 to rotate. The second gear 86 meshes with the second rack 83, causing the second crossbeam 87 and the third scanner 89 to move laterally to the left along the second sliding frame 82. Since the first sliding block 814 is in contact with the left side of the second sliding frame 82 and restricts it, when the second gear 86 moves to the left, the first pulley 812 moves to the right, thereby driving the first pulley 812 to rotate. The first pulley 812 drives the fourth rotating shaft 811 to rotate, and the first sliding shaft 816 drives the first rotating frame 810 to swing back and forth. The first rotating frame 810 drives the third rotating shaft 88 to swing back and forth, thereby causing the third scanner 89 to swing back and forth, realizing multi-angle detection of the bottom surface. When the second rack 83 moves to the left side and meshes with the third gear 8110, the third motor 819 drives the second rack 83 to advance at a constant speed through the third gear 8110. The third scanner 89 rotates around the third rotating shaft 88 and scans the bottom surface of the component. During the scanning process, the identification light spot 12 on the conical top block 75 is captured in real time by the shooting and identification component 11 on the horizontal plate 10. The controller determines the tilt state of the component based on the spatial coordinates of each light spot through the built-in algorithm of the control panel 16, and finely adjusts the magnetic levitation height below each conical top block 75 so that the component always maintains a relative horizontal reference, eliminating the measurement error caused by uneven support surface.

[0037] After scanning is completed, each component is reset, and cylinder 31 lifts sliding frame 3 so that electric conveying roller 5 can support the component again and transport it out of the detection area, thereby completing the complete flatness detection process of the prefabricated component with full surround, vibration resistance, adaptive irregular surface and horizontal correction.

[0038] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
