Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a rolling line-laying device for curved surfaces of balcony structures and its usage method. Background Technology
[0002] With the diversification of architectural forms, curved balconies have become a mainstream design to enhance the aesthetics of facades. In the construction of curved balconies, horizontally laying out the inner and outer surfaces of the structure is a crucial step to ensure construction accuracy and decorative effect. Currently, two main methods are used for laying out curved balconies: traditional hanging lines and laser levels. The former marks positions by hanging baselines, while the latter uses a laser level as a reference, with manual tracing along the trajectory to complete the layout.
[0003] Existing line-laying technologies have drawbacks: traditional hanging lines are affected by the undulations of curved walls, making it impossible to form a stable horizontal baseline, resulting in insufficient line-laying accuracy; when using laser levels, the laser cannot penetrate curved surfaces, and there is a lack of efficient line-laying solutions in the industry that are suitable for curved balconies. Summary of the Invention
[0004] To overcome the above shortcomings, the present invention provides a rolling line laying device and method for use on curved surfaces of balconies, aiming to improve the technical problems of traditional line laying being affected by the undulations of curved walls, failing to form a stable horizontal baseline, having insufficient line laying accuracy, and the inability of laser levels to penetrate curved surfaces.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rolling line-laying device for curved balcony structures, used for horizontal line-laying operations on curved balcony walls, including a support frame, rollers installed on the inner side of the support frame, the rollers being arranged to fit against the two sides and the top surface of the curved wall respectively; fixed blocks are provided on both sides of the support frame, sensors are installed on the fixed blocks, the fixed blocks are connected to the rollers through an electric telescopic rod, the sensors are signal-connected to a control center, and the control center is control-connected to the electric telescopic rod; a slide rail is fixedly installed on the inner side of the support frame, a slider is fitted on the slide rail, and the slider is fixedly locked to the slide rail by bolts; a fixing plate is connected to the side of the slider, a sleeve is installed on the fixing plate, a talcum powder pen is installed inside the sleeve, a tightening spring is provided between the sleeve and the talcum powder pen, and a dust-sweeping component is fixedly installed on the fixing plate.
[0006] Preferably, the dust removal assembly includes a motor and a cleaning brush. The motor is fixedly mounted on a fixed plate, and the output end of the motor is fixedly connected to the cleaning brush, which is attached to the surface of the curved wall.
[0007] Preferably, the cleaning brush and the talcum pen are at the same horizontal height, and the cleaning brush is located in front of the talcum pen along the direction of movement of the support frame.
[0008] Preferably, the end of the talcum pen near the tightening spring is provided with a stop block, and the end of the sleeve away from the tightening spring is provided with a limiting structure that matches the stop block.
[0009] Preferably, the outer wall of the sleeve is machined with external threads, the fixing plate has a threaded hole, and the sleeve is threadedly connected to the threaded hole through the external threads.
[0010] Preferably, one end of the clamping spring abuts against the inner wall of the sleeve, and the other end of the clamping spring abuts against the end of the talcum pen.
[0011] Preferably, the slide rail is provided with a scale for positioning the wire laying height.
[0012] A method for using a rolling wire laying device for curved surfaces of a balcony structure includes the following steps:
[0013] S1: The support frame is placed against the curved wall of the balcony. The sensor on the fixed block detects the distance to the curved wall and transmits it to the control center. The control center drives the electric telescopic rod to automatically adjust its length so that the rollers fit tightly against the two sides and the top of the curved wall, completing the initial positioning of the device.
[0014] S2: Referring to the scale on the slide rail, adjust the slider to the preset layout point according to the horizontal layout position requirements of the curved wall by sliding along the length of the slide rail;
[0015] S3: Tighten the bolts to lock the slider onto the slide rail, thus locking the slider position.
[0016] S4: Install the talcum pen inside the sleeve, tighten the spring to push the talcum pen, so that the talcum pen is always pressed against the curved wall surface;
[0017] S5: Start the motor to drive the sweeping brush to rotate and sweep impurities on the curved wall surface; push the support frame at a constant speed along the horizontal contour of the curved wall, and the talcum pen moves synchronously with the support frame to complete continuous horizontal lines on the curved wall surface.
[0018] Preferably, when installing the talcum pen in S4, first remove the sleeve, put the talcum pen into the sleeve, then install the top spring, and then thread the sleeve onto the fixing plate to complete the installation.
[0019] Preferably, in S5, the support frame moves at a constant speed along the curved surface, and the talcum pen draws continuous and uniform horizontal control lines under the action of the tightening spring.
[0020] The present invention has the following beneficial effects:
[0021] 1. The rollers on the inner side of the support frame are respectively attached to the two sides and the top of the curved wall. During the rolling process, the relative position of the support frame and the curved wall can always be kept stable, allowing the support frame to move smoothly along the tangent of the curved surface. The laying trajectory can perfectly match the outline of the curved wall, fundamentally solving the problem that traditional laying methods cannot adapt to curved structures, and greatly improving the accuracy of horizontal laying of curved walls on balconies.
[0022] 2. The slide rail and the sliding and locking slider work together, and with the scale markings on the slide rail, the line position can be quickly and accurately adjusted. The slider can be firmly locked in the designated position on the slide rail with bolts, eliminating the need for repeated position calibration, simplifying the line setting operation process, effectively shortening the adjustment and preparation time before line setting, and improving the efficiency of construction positioning.
[0023] 3. The tightening spring inside the sleeve continuously applies a stable tightening force to the stalactite pen, ensuring that the stalactite pen always adheres tightly to the curved wall surface, guaranteeing uniform pressure during the drawing process, and producing continuous, clear, and straight lines. The sleeve adopts a threaded connection structure, which allows for quick disassembly and replacement of the stalactite pen, avoiding the impact of wear and tear on the construction progress due to the wear and tear of the drawing components, and improving the continuity of the line laying operation.
[0024] 4. The motor-driven cleaning brush operates synchronously, which can clean the dust and impurities on the surface of curved walls in real time, clear the path of the talcum pencil to be drawn in advance, eliminate the problem of blurred lines caused by impurities, further ensure clear and complete lines, and continuously improve the overall accuracy and construction quality of curved wall layout.
[0025] 5. Sensors are installed on the fixed block to detect the distance to the curved wall in real time and transmit control signals to drive the electric telescopic rod to adaptively adjust the telescopic length. This can perfectly adapt to curved walls of different thicknesses, ensuring that the rollers are always in close contact with the wall without gaps, making the support frame move more smoothly and greatly improving the adaptability and versatility of the device for various curved balcony structures.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Example 1, refer to Figures 1-8A rolling line-laying device for curved balcony structures is disclosed, used for horizontal line-laying operations on curved balcony walls 2. It includes a support frame 1, which serves as the overall load-bearing structure of the device, stably supporting all functional components. Rollers 3 are installed on the inner side of the support frame 1, respectively conforming to the two sides and top surface of the curved wall 2. As the rollers 3 roll, they firmly adhere to the wall contour, allowing the support frame 1 to move smoothly along the curved surface without deviation. Fixing blocks 4 are located on both sides of the support frame 1, providing a stable mounting platform for sensors. Sensors are installed on the fixing blocks 4, which can detect the distance to the curved wall 2 in real time. The fixing blocks 4 are connected to the rollers 3 via an electric telescopic rod 5. The sensors are signal-connected to a control center, which in turn is control-connected to the electric telescopic rod 5. The control center can precisely adjust the extension length of the electric telescopic rod 5 based on the signals transmitted by the sensors, ensuring that the rollers 3 always maintain a seamless contact with curved wall 2 of varying thicknesses. The sensors are GP2Y0A infrared ranging sensors; the electric telescopic rod 5 is an XTL series electric push rod. A slide rail 8 is fixedly installed on the inner side of the support frame 1. The slide rail 8 provides a straight and stable sliding track for the slider 9. The slider 9 is fitted onto the slide rail 8. The slider 9 can freely adjust its line-laying position along the slide rail 8. The slider 9 is locked and fixed to the slide rail 8 by bolts 10. The bolts 10 can firmly fix the slider 9 in the designated position to prevent displacement during operation. A fixing plate 11 is connected to the side of the slider 9. The fixing plate 11 serves as the core functional integration carrier. A sleeve 7 is installed on the fixing plate 11. A steatite pen 6 is installed inside the sleeve 7. A tensioning spring 12 is provided between the sleeve 7 and the steatite pen 6. The tensioning spring 12 continuously applies a uniform tensioning force to the steatite pen 6, keeping the steatite pen 6 always in contact with the wall surface for drawing lines. A dust-removing component is fixed on the fixing plate 11. The dust-removing component can clean impurities on the wall surface in advance to ensure clear lines.
[0038] Example 2, refer to Figures 1-8 Based on Embodiment 1, the dust removal assembly includes a motor 14 and a cleaning brush 15. The motor 14 provides continuous and stable power for the cleaning operation. The motor 14 is fixedly installed on the fixed plate 11 and adjusts its height position synchronously with the slider 9. The output end of the motor 14 is fixedly connected to the cleaning brush 15. The cleaning brush 15 is attached to the surface of the curved wall 2. When the motor 14 is running, it can directly drive the cleaning brush 15 to rotate, effectively removing dust particles from the wall surface and preventing impurities from affecting the line drawing effect of the talcum pen 6.
[0039] The cleaning brush 15 and the talcum powder pen 6 are at the same horizontal height to ensure that the cleaning area and the drawing area are completely aligned. The cleaning brush 15 is located in front of the talcum powder pen 6 along the moving direction of the support frame 1. When the support frame 1 moves, the cleaning brush 15 will first clean the path to be drawn, creating a clean drawing environment for the talcum powder pen 6, avoiding the problems of blurry or broken lines from the source, and further improving the accuracy of the line drawing.
[0040] The end of the talcum pen 6 near the tightening spring 12 is provided with a stop block 13, and the end of the sleeve 7 away from the tightening spring 12 is provided with a limiting structure that matches the stop block 13. The stop block 13 and the limiting structure cooperate and engage with each other, which can effectively prevent the talcum pen 6 from falling out of the sleeve 7 during the line drawing process, ensuring that the line drawing operation is carried out continuously and stably, and the construction will not be interrupted due to the falling off of the parts.
[0041] The outer wall of the sleeve 7 is machined with external threads, and the fixing plate 11 is provided with threaded holes. The sleeve 7 is connected to the threaded hole through the external threads. The threaded connection method is simple and convenient to install and remove. The sleeve 7 can be quickly installed and removed without the need for additional tools, which facilitates timely replacement of worn-out steatite pen 6 and improves the overall efficiency and continuity of the line laying operation.
[0042] One end of the clamping spring 12 abuts against the inner wall of the sleeve 7, and the other end of the clamping spring 12 abuts against the end of the steatite pen 6. The clamping spring 12 is always in an elastic extension state, which can continuously provide a stable and uniform clamping force to the steatite pen 6, so that the steatite pen 6 can always fit on the undulating surface of the curved wall 2, and the drawn lines are continuous and uniform.
[0043] The slide rail 8 is equipped with a scale for positioning the laying height. The scale markings are clear and intuitive. When adjusting the position of the slider 9, the laying height can be determined directly by referring to the scale. There is no need for repeated measurement and calibration, which greatly improves the speed and accuracy of laying and positioning and shortens the preparation time before construction.
[0044] Example 3, referring to Figures 1-8 A method for using a curved surface rolling wire laying device for a balcony structure includes the following steps:
[0045] S1 attaches the support frame 1 to the curved wall 2 of the balcony. The sensor on the fixing block 4 detects the distance to the curved wall 2 and transmits it to the control center. The control center drives the electric telescopic rod 5 to automatically adjust its length so that the roller 3 fits tightly against the two sides and the top of the curved wall 2, completing the initial positioning of the device. The automatic adjustment method makes the positioning more accurate and more efficient in adapting to walls of different thicknesses.
[0046] S2 refers to the scale on the slide rail 8. According to the horizontal layout position requirements of the curved wall 2, slide the slider 9 along the length of the slide rail 8 to the preset layout point. The scale-assisted positioning makes the adjustment more intuitive and accurate.
[0047] S3 Tighten bolt 10 to lock slider 9 onto slide rail 8, thus locking slider 9 in position. After locking, slider 9 will not move, ensuring that the line laying position remains accurate and unchanged.
[0048] S4 installs the talcum pen 6 inside the sleeve 7, and the spring 12 pushes the talcum pen 6 to keep the talcum pen 6 pressed against the surface of the curved wall 2. The continuous pressing force ensures the line adherence.
[0049] S5 starts the motor 14 to drive the cleaning brush 15 to rotate, cleaning the surface of the curved wall 2 and clearing the marked path in advance. It pushes the support frame 1 at a constant speed along the horizontal contour of the curved wall 2. The talcum pen 6 moves synchronously with the support frame 1 to complete continuous horizontal lines on the surface of the curved wall 2. The constant speed movement makes the lines straighter.
[0050] When installing the talcum pen 6 in S4, first remove the sleeve 7, put the talcum pen 6 into the sleeve 7, then install the top spring 12, and then thread the sleeve 7 onto the fixing plate 11 to complete the installation. The step-by-step assembly method is simple and easy to operate, and can quickly complete the replacement of the talcum pen 6. At the same time, it allows the stop block and the limiting structure to cooperate naturally to achieve the anti-detachment effect.
[0051] In S5, the support frame 1 moves at a constant speed along the curved surface. This constant speed allows the line laying trajectory to better conform to the wall contour. The steatite pen 6 draws continuous and uniform horizontal control lines under the action of the top spring 12. Combined with the cleaning effect of the cleaning brush 15, clear, straight, and precise horizontal line laying lines are finally obtained.
[0052] Working Principle: The entire device is installed on the curved wall 2. Multiple sets of rollers 3 are installed on the inner side of the support frame 1, and the rollers 3 are respectively attached to the two sides and the top surface of the curved wall 2. Fixed blocks 4 are provided on both sides of the support frame 1, and sensors are installed on the fixed blocks 4. The sensors detect the distance to the curved wall 2 in real time. After the detection signal is transmitted to the control center, the control center issues an adjustment command to the electric telescopic rod 5, automatically adjusting the extension length of the electric telescopic rod 5 so that the rollers 3 are always in close contact with the curved wall 2 of different thicknesses, ensuring that the support frame 1 can roll smoothly and without deviation along the curved wall 2. A slide rail 8 is fixedly installed on the inner side of the support frame 1. The slide rail 8 and the slider 9 form a sliding fit. Bolts 10 pass through the slider 9 and the slide rail 8, locking the slider 9 in a designated position on the slide rail 8, realizing flexible adjustment and precise positioning of the line laying position.
[0053] A fixing plate 11 is fixedly connected to the side of the slider 9. A sleeve 7 is threaded onto the fixing plate 11. Inside the sleeve 7, a steatite pen 6 and a tightening spring 12 are sequentially assembled. A stop block 13 is provided at the end of the steatite pen 6 near the tightening spring 12, and a matching limiting structure is provided at the end of the sleeve 7 away from the tightening spring 12. The stop block 13 and the limiting structure engage with each other to effectively prevent the steatite pen 6 from falling off during operation. The two ends of the tightening spring 12 abut against the inner wall of the sleeve 7 and the end of the steatite pen 6, respectively, continuously applying a tightening force towards the curved wall 2 to the steatite pen 6, ensuring that the steatite pen 6 always fits tightly against the wall. A motor 14 is installed on the fixing plate 11, and the output end of the motor 14 is connected to a cleaning brush 15. Dust and impurities easily remain on the surface of the curved wall 2, which can hinder the close contact between the steatite pen 6 and the wall, resulting in blurred lines, broken lines, and poor line straightness, directly reducing the accuracy of line drawing. Therefore, the motor 14 drives the cleaning brush 15 to rotate synchronously, which can clean the impurities on the wall in advance and ensure that the drawing area is clean. When the support frame 1 is pushed to roll laterally along the curved wall 2, the roller 3 guides synchronously along the curved contour, the cleaning brush 15 completes the wall cleaning in advance, and the talcum pen 6 moves synchronously with the support frame under the continuous pressing action of the top spring 12, completing a continuous, precise, and perfectly conforming horizontal line laying operation on the clean curved wall 2 surface.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
