[0019] The present invention drives the intermediate component and the detection plate to rotate on the wall surface through the circular plate, so that the roller group rotates on the wall surface. When the wall surface is uneven, the detection plate will tilt accordingly. The deviation plate and the detection plate cooperate. When the detection plate tilts, the deviation plate is used as an extension. When the deviation plate has a small offset, the end displacement distance is large, making the wall flatness detection result more obvious. The detection plate is used to rotate to detect flatness, thereby improving the detection efficiency.

[0020] Furthermore, since the cross-slit rotating column is aligned with the expansion joint of the curtain wall, when detecting the flatness of the curtain wall, when the middle piece is in a horizontal or vertical state, the pressurized arc ball piston is fully pressed into the middle piece, and the positioning card is extended to prevent the detection plate from rotating, thereby avoiding the concave part of the cross seam causing the detection plate to fluctuate and affect the detection results.

[0021] Furthermore, when the wall surface is uneven, the deviation plate pushes the positioning ring and the pressure block to compress the coarse air bag, thereby sending the gas inside the coarse air bag into the fine air bag. Since the cross-sectional area of ​​the coarse air bag is larger than that of the fine air bag, when the deformation of the coarse air bag is small, the fine air bag can also produce a large deformation, further expanding the influence of the inclination of the deviation plate on the extension distance of the indicator block, so as to prompt the position of the protrusion on the wall surface for subsequent correction of the wall surface.

[0022] Furthermore, the detection plate is used to drive the scraper to rotate, and the support spring and the slot apply resistance to the slider to remove small cement block protrusions on the wall to avoid affecting the flatness detection data. When encountering large cement block protrusions, the scraper is retracted into the detection plate for avoidance. At the same time, since the scraper has contacted the protruding cement block, the scraper will leave marks on the cement block, so that the staff can find the protrusion and remove it.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] Example 1: This example proposes a device for detecting the flatness of a building curtain wall. Figure 1 As shown, it includes a detection frame 1, which adopts an L-shaped structure. The bottom of the detection frame 1 is rotatably connected to a universal wheel 2. A handle 4 is installed at the height of the horizontal surface of the detection frame 1. Workers hold the handle 4 to push the detection frame 1.

[0041] A detection assembly 5 is provided on one side of the vertical surface of the detection frame 1 , and a counterweight 3 is fixedly installed on the top of the horizontal surface of the detection frame 1 . The counterweight 3 is used as a counterweight to prevent uneven force on the detection frame 1 .

[0042] like Figure 2 and Figure 3 As shown, the detection assembly 5 includes a rotating part, a circular plate 54, an intermediate part 55, a detection plate 56, a roller group, a deviation plate 58 and a buffer air spring 510. One end of the rotating part is connected to the circular plate 54. The rotating part includes a motor 51, a rotating wheel 52 and a guide column 53. The motor 51 is fixedly installed on one side of the vertical surface of the detection frame 1. The drive shaft of the motor 51 is fixedly connected to the rotating wheel 52. The motor 51 and the rotating wheel 52 are respectively located on both sides of the detection frame 1. The guide column 53 is fixedly installed on one side of the rotating wheel 52. The buffer air spring 510 is elastically connected between the rotating wheel 52 and the circular plate 54. A plurality of guide columns 53 are provided, and are distributed in a circular shape with equal angles on the side of the rotating wheel 52. The circular plate 54 slides on the guide column 53.

[0043] like Figure 3 As shown, a U-shaped intermediate member 55 is fixedly mounted on the side of the circular plate 54 away from the rotating member. The opening of the intermediate member 55 is rotatably connected to a detection plate 56, which is internally connected to the roller assembly. The rotating member drives the circular plate 54 to rotate, thereby rotating the intermediate member 55 and the detection plate 56, causing the roller assembly to rotate on the wall.

[0044] First, push the detection frame 1 toward the wall and make the roller group stick to the wall. Use the wall and the detection frame 1 to compress the buffer air spring 510. When the wall is tilted, the detection plate 56 and the roller are pressed against the wall, so the detection plate 56 is tilted. The detection plate 56 faces one side of the middle part 55 and is fixed with a deviation plate 58 near both ends. A buffer air spring 510 is set between the circular plate 54 and the rotating part. The buffer air spring 510 serves as a buffer to make up for and release the gap so that the detection plate 56 can rotate.

[0045] In most cases, the wall has a small inclination angle, and the inclination of the detection plate 56 is not obvious when directly observing it. Therefore, the deviation plate 58 is used as an extension. When the detection plate 56 tilts, the deviation plate 58 will no longer be parallel to the ground. Even if the angle between the detection plate 56 and the vertical plane is small, that is, the angle of the deviation plate 58 is small, the displacement distance of the end of the deviation plate 58 is large, making the wall flatness detection result more obvious.

[0046] The roller group includes a first roller 57 and a second roller 59. The first roller 57 and the second roller 59 are located on the same axis. The first roller 57 and the second roller 59 are rotationally connected via a rotating shaft. The ends of the first roller 57 and the second roller 59 are rotationally connected to the detection frame 1. The connecting end of the first roller 57 and the second roller 59 is located at the center of the circular plate 54. The first roller 57 and the second roller 59 rotate in opposite directions. The first roller 57 and the second roller 59 both roll on the wall. The arc surfaces of the first roller 57 and the second roller 59 extend from the inside of the detection plate 56. When the detection plate 56 rotates, the first roller 57 and the second roller 59 rotate on the wall. Since the connecting end of the first roller 57 and the second roller 59 is located at the center of the circular plate 54, the first roller 57 and the second roller 59 rotate in opposite directions.

[0047] In this embodiment, the intermediate member 55 and the detection plate 56 are driven to rotate on the wall by the circular plate 54, so that the roller group rotates on the wall. When the wall is uneven, the detection plate 56 will tilt accordingly. The deviation plate 58 cooperates with the detection plate 56. When the detection plate 56 tilts, the deviation plate 58 is used as an extension. When the deviation plate 58 has a small offset, the end displacement distance is large, making the wall flatness detection result more obvious. The detection plate 56 is used to rotate and detect flatness, thereby improving the detection efficiency.

[0048] Example 2: Based on Example 1, this example proposes a building curtain wall flatness detection device, such as Figure 10 and Figure 11As shown, the avoidance component 8 includes a seam rotating column 81, a center of gravity offset cross plate 82, a hydraulic pipe 83, a pressurized arc ball piston 84, a positioning clamp 85 and a pressure safety valve 86. The seam rotating column 81 is fixedly installed at the center of the detection plate 56, and the seam rotating column 81 is aligned with the cross seam of the curtain wall installation. The center of gravity offset cross plate 82 is sleeved on the rotating shaft where the middle piece 55 and the circular plate 54 are connected. The center of gravity offset cross plate 82 is connected to the rotating shaft through a bearing. Four hydraulic pipes 83 are opened inside the middle piece 55, and the two ends of the hydraulic pipe 83 are respectively slidably connected to the pressurized arc ball piston 84 and the positioning clamp 85. The four pressurized arc ball pistons 84 are distributed in a cross shape, and the positioning clamp 85 is located between the middle piece 55 and the detection plate 56. When the positioning clamp 85 is extended, the middle piece 55 and the detection plate 56 are in a parallel state.

[0049] The center of gravity of the gravity-shifting cross plate 82 is near the bottom, and the pressure required to actuate the pressurized arc ball piston 84 is low. Therefore, when the gravity-shifting cross plate 82 contacts the pressurized arc ball piston 84, the pressurized arc ball piston 84 is unable to move the gravity-shifting cross plate 82. The pressurized arc ball piston 84 is actuated, causing the hydraulic pressure in the hydraulic pipe 83 to extend the positioning clamp 85. The positioning clamp 85 is positioned between the intermediate member 55 and the detection plate 56, and the intermediate member 55 and the detection plate 56 are parallel. At this point, the detection plate 56 cannot rotate. Because the extension is hydraulically controlled, the pressurized arc ball piston 84 automatically returns to its original position when the pressure is removed from the pressurized arc ball piston 84.

[0050] A pressure relief valve 86 is fixedly mounted in the middle of hydraulic pipe 83. It opens only when the pressurizing arc ball piston 84 is fully pressed into the intermediate member 55. The diameter of the pressurizing arc ball piston 84 is 2 mm. Each straight plate of the gravity center offset cross plate 82 also has a diameter of 2 mm. The cross seam width of a typical curtain wall is 6-15 mm.

[0051] In this embodiment, since the seam rotating column 81 is aligned with the curtain wall expansion joint, when detecting the flatness of the curtain wall, when the middle piece 55 is in a horizontal or vertical state, the pressurized arc ball piston 84 is fully pressed into the middle piece 55, and the positioning card 85 is extended to prevent the detection plate 56 from rotating, thereby preventing the concave part of the cross seam from causing the detection plate 56 to fluctuate and affecting the detection results.

[0052] Example 3: Based on Example 1 or 2, this example proposes a building curtain wall flatness detection device, such as Figure 3 and Figure 4As shown, a position indicator 7 is provided on the side of the detection frame 1, and the position indicator 7 includes a ring plate 71, a partition plate 73, an extrusion piece, a spring sheet 76 and a coarse air bag 77. The ring plate 71 is fixedly mounted on one side of the vertical surface of the detection frame 1, and the outer arc surface of the ring plate 71 is fixedly mounted with the partition plate 73. The partition plate 73 and the ring plate 71 form a recess, and the coarse air bag 77 is located in the recess. Both ends of the spring sheet 76 are fixedly mounted on the side of the partition plate 73, and the inner arc surface of the spring sheet 76 is abutted against the outer wall of the coarse air bag 77. The outer arc surface of the spring sheet 76 is fixedly connected to the extrusion piece.

[0053] like Figure 9 As shown, a plurality of partition plates 73 are provided, and the plurality of partition plates 73 are distributed in a circular shape with equal angles on the outer arc surface of the ring plate 71. The plurality of partition plates 73 and the ring plate 71 form a plurality of recesses. A closing plate 72 is fixedly installed on the side of the ring plate 71. The ring plate 71, the closing plate 72, the partition plate 73 and the positioning ring 74 close the recess. The ring plate 71 and the closing plate 72 both adopt a circular ring structure, and the circular plate 54 passes through the center of the ring plate 71 and the closing plate 72.

[0054] The coarse air bag 77 is completely enclosed in the recess by the cooperation of the ring plate 71, the closing plate 72, the partition plate 73 and the positioning ring 74. When the deviation plate 58 deviates, the deviation plate 58 pushes the extrusion part to move, and the extrusion part pushes the auxiliary cleaning part 6 to squeeze the coarse air bag 77.

[0055] like Figure 7 and Figure 8 As shown, the interior of the coarse airbag 77 is fixedly connected to a supporting metal tube 78, the end of the supporting metal tube 78 is fixedly installed with a slide 711, the interior of the slide 711 is slidably connected to an indicator block 710, the end of the indicator block 710 is fixedly connected to a fine airbag 79, and the end of the supporting metal tube 78 is connected to the fine airbag 79.

[0056] When the coarse airbag 77 is squeezed, the gas inside the coarse airbag 77 enters the fine airbag 79 along the supporting metal tube 78, and the fine airbag 79 expands to push out the indicator block 710, thereby showing the worker the position of the protrusion of the inclined wall so that the worker can make subsequent corrections.

[0057] The extrusion piece includes a positioning ring 74 and a pressure block 75. The pressure block 75 adopts a semicircular structure. The arc surface of the pressure block 75 is fixedly connected to the arc surface of the spring sheet 76. The side of the pressure block 75 away from the spring sheet 76 is fixedly connected to the positioning ring 74. The outer arc surface of the positioning ring 74 contacts the deviation plate 58.

[0058] The plurality of spring sheets 76 support the pressure block 75 and the positioning ring 74. The deflection plate 58 pushes the positioning ring 74, causing the spring sheets 76 to deform. The coarse airbag 77 is then squeezed by the coarse airbag 77. Because the recess is sealed by the ring plate 71, the closing plate 72, the partition plate 73, and the positioning ring 74, the gas within the coarse airbag 77 can only flow into the supporting metal tube 78. Furthermore, because the cross-sectional area of ​​the coarse airbag 77 is larger than that of the fine airbag 79, even when the coarse airbag 77 deforms slightly, the fine airbag 79 can also deform significantly. Simultaneously, the elastic force of the spring sheets 76 helps the positioning ring 74 and the pressure block 75 return to their original position.

[0059] In this embodiment, when the wall surface is uneven, the deviation plate 58 pushes the positioning ring 74 and the pressure block 75 to compress the coarse air bag 77, thereby sending the gas inside the coarse air bag 77 into the fine air bag 79. Since the cross-sectional area of ​​the coarse air bag 77 is larger than the cross-sectional area of ​​the fine air bag 79, when the deformation of the coarse air bag 77 is small, the fine air bag 79 can also produce a large deformation, further expanding the influence of the inclination of the deviation plate 58 on the extension distance of the indicator block 710, so as to prompt the position of the protrusion on the wall surface for subsequent correction of the wall surface.

[0060] Example 4: Based on the above-mentioned Example 1 or 3, this example proposes a building curtain wall flatness detection device, such as Figure 5 and Figure 6 An auxiliary cleaning part 6 is provided inside the detection plate 56, and the auxiliary cleaning part 6 includes a scraper 61, a slider 62 and a support spring 66. The slider 62 slides inside the detection plate 56, and the slider 62 is tilted. The end of the slider 62 is elastically connected to the support spring 66 between the detection plate 56, and the other end of the slider 62 is fixedly connected to the scraper 61. The length of the scraper 61 is shorter than the length of the first roller 57 extending from the detection plate 56. An inclined slide 63 for the slider 62 to slide is provided in the detection plate 56.

[0061] Two slots 65 are formed on the side of the slider 62 . A clip 64 is fixedly installed inside the detection plate 56 . The clip 64 engages with the slot 65 . Initially, the clip 64 is inserted into the slot 65 near the support spring 66 .

[0062] As the inspection plate 56 rotates, the scraper 61 on the inspection plate 56 first contacts the protruding cement block on the wall. Because the clip 64 is initially inserted into the slot 65 near the support spring 66, the support spring 66 and the slot 65 exert resistance on the slider 62. When the resistance is greater than the connecting force between the cement block and the wall, the protruding cement block is scraped away. When the support spring 66 and the slot 65 exert resistance on the slider 62, and the resistance is less than the connecting force between the cement block and the wall, the slider 62 will be stuck in another slot 65 to avoid the protruding cement block. Since the scraper 61 has already contacted the protruding cement block, the scraper 61 will leave a scraping mark on the cement block.

[0063] In this embodiment, the detection plate 56 is used to drive the scraper 61 to rotate, and the support spring 66 and the slot 65 apply resistance to the slider 62 to remove small cement block protrusions on the wall to avoid affecting the flatness detection data. When encountering large cement block protrusions, the scraper 61 is retracted into the detection plate 56 for avoidance. At the same time, since the scraper 61 has been in contact with the protruding cement block, the scraper 61 will leave a mark on the cement protrusion, so that the staff can find the protrusion and remove it.

[0064] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
