Description

Technical Field

[0001] This invention belongs to the field of pipeline installation technology, specifically relating to a visualization AR construction method for large-area pipeline installation in ultra-high-rise buildings and a pipeline location detection and correction device. Background Technology

[0002] Pipeline installation accounts for four of the nine major sub-projects in building construction (building electrical engineering, building water supply, drainage and heating engineering, and communication and air conditioning engineering), making it a crucial construction phase. Installation work involves multiple teams working in shifts, often resulting in common problems such as pipe collisions, misinstallation, insufficient pipe elevation, and excessive bracket spacing. These issues prevent timely completion and significantly reduce construction efficiency. While AR technology has advanced rapidly, leading to the emergence of many excellent foreign AR software programs, AR applications in the construction industry require a cumbersome process of uploading and downloading models. Furthermore, after pipe installation, curved pipes are needed to connect perpendicular corners. If the installation positions of the two perpendicular pipes do not meet requirements, connecting the curved pipe is difficult. Additionally, adjusting the pipe positions after installation to accommodate the curved pipe connection is also challenging. Therefore, a device is needed to detect whether the relative positions of adjacent perpendicular pipes meet installation requirements and to correct the pipe positions accordingly. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a visualization AR construction method for large-area pipeline installation in ultra-high-rise buildings, so as to solve the technical problem that the existing AR application requires a model uploading and downloading process, which is very inconvenient to use.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0006] S1. Review, confirm, and finalize the Revit model for engineering designs that require pipeline installation;

[0007] S2. Use Navisworks' collision detection function to modify and improve the model, forming a virtual template model.

[0011] S6. Use AR visualization to combine the imported model with the actual site.

[0012] S7 and AR models are precisely calibrated, and the error between the calibrated model and the actual site is less than 10mm.

[0013] S8 and AR models guide pipeline construction.

[0014] Another technical problem to be solved by the present invention is to provide a pipeline position detection and correction device using the visualization AR construction method for large-area pipeline installation in ultra-high-rise buildings as described above. The device is characterized by comprising several position detection and correction devices, each including a detachable frame for supporting and correcting the pipeline; a first detector for detecting the relative position of two vertical pipelines is provided inside the frame; a moving unit for moving the frame is arranged parallel to the frame; two suction cups are provided on the side of the moving unit away from the frame, rotatably connected to the moving unit via a first motor; the suction cups are adhered to the wall above the corresponding pipeline. When one of the suction cups adheres to the wall, the first motor drives the moving unit to rotate around the suction cup. A tilt correction unit is located on the side of the frame away from the moving unit. The tilt correction unit includes a telescopic cylinder connected to the frame. An inverted T-shaped plate is connected to the telescopic cylinder. A support block for supporting the pipe is rotatably connected to the inverted T-shaped plate. The support block is parallel to the frame. An arc-shaped toothed ring is connected to the bottom of the support block. A second motor is connected to the inverted T-shaped plate. An adjusting gear meshing with the arc-shaped toothed ring is connected to the power end of the second motor. Support units that can extend and retract to support the sidewalls of the pipe are located on opposite sides of the frame.

[0015] Furthermore, a sliding groove is provided inside the support block; a slider is slidably connected inside the sliding groove; a through groove communicating with the sliding groove is provided at the bottom of the support block; a rotating gear is rotatably connected to the side wall of the through groove via a third motor; a toothed plate meshing with the rotating gear is provided at the bottom of the slider; and a second detector for detecting the parallelism of the pipe is also provided inside the frame.

[0016] Furthermore, the moving unit includes a track and a pulley that is rolled on the track; the pulley is rotatably connected to the frame via a fourth motor; the suction cup is rotatably connected to the track; a circular groove coaxial with the suction cup is opened on the track; an internal gear ring is coaxially provided in the circular groove; a first motor is connected to the side wall of the suction cup; the power end of the first motor is coaxially connected to a rotating gear that meshes with the internal gear ring.

[0017] Furthermore, the support unit includes sleeves rotatably connected to the two inner sides of the frame; a telescopic rod is connected inside the sleeve; and a clamping block supporting the side wall of the pipe is rotatably connected to the rod.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. Utilizing an application, no download or installation is required; simply open the application to use it, making it extremely convenient. Furthermore, when users are guided through construction work using the virtual reality system, the displayed model simulates the relative positions of all installed pipelines, allowing them to see the distribution of pipelines after installation and avoiding pipeline collisions during actual installation. High-precision installation guidance is provided for underground pipeline manholes, electrical shafts, fire branch pipes, equipment rooms, etc., through transparency comparison, improving installation accuracy, reducing installation time wasted due to incomplete installation, effectively shortening the construction cycle, and improving construction efficiency.

[0021] 2. A suction cup is attached to the wall, and the first motor controls the track to rotate around the suction cup. This causes the first detector to rotate from one pipe to another under the rotation of the frame, thus completing the detection of the arc length of the two vertical pipes. After comparing the value with that of the curved pipe, the tilt correction unit can correct the tilt and horizontal offset of the pipe.

[0022] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention.

Detailed Implementation

[0029] Example 1:

[0030] This invention provides a visualization-based AR construction method for large-area pipeline installation in ultra-high-rise buildings, comprising the following steps:

[0031] S1. First, review the Revit models of all disciplines involved in the pipeline installation project design. After confirming that the electrical, plumbing, HVAC, and fire protection systems are consistent with the construction site, proceed with the model assembly.

[0032] S2. Then, using Navisworks' collision detection function, the model was modified and improved, and a preliminary full-discipline model of the virtual template was formed; after the model was completed, the scheme was reviewed with the design unit.

[0033] S3. Through BIM virtual reality platforms such as 3DMax and FUZOR, designers communicate and exchange ideas regarding the design scheme. The intuitive visual representation of the model allows for verification of the correctness and rationality of the design intent and form. This step is crucial because pipeline installation projects involve more complex materials and wiring than other disciplines, and traditional CAD drawings are prone to human error in annotation and incomplete descriptions. Therefore, having designers review the model through a virtual reality platform is equivalent to having them re-examine the provided drawings, preventing losses caused by errors in the construction blueprints.

[0034] S4 is an application written in HTML that exists in the browser of a smart mobile device. It does not require downloading or installation, and the input data is stored on the network. When you open the computer and access the web interface, you can import project information and model data to the server.

[0035] S5. After importing the model into the Web, the model can be displayed on the computer. You can find the QR code markers in the model, set the QR code locations on the Web, print out the QR codes, and stick them to the designated locations on site. Importing the model will achieve a 1:1 fit with the site.

[0036] S6. After importing the model, the site and the model need to be compared. Through the immersive and comprehensive visualization of AR, the effects of pipeline materials over a large area can be selected. This is something that cannot be experienced in a small-space model. At the same time, the biggest difference from the rendering is that the sense of space and mobility brought by AR technology allows all parties involved to participate well in the project space. It makes all installation work interactive, thereby improving the efficiency of scheme determination and saving on-site construction time.

[0037] S7. After the model is displayed, the model is imported again using the principle of two points and one line for precise calibration. The error between the calibrated model and the actual site is less than 10mm.

[0038] S8. AR model guides pipeline construction. AR technology is used to bring the BIM model into the construction site to achieve a 1:1 high-precision verification between the BIM model and the on-site pipelines. AR technology is used to check pipeline size, installation direction, installation positioning, installation integrity, etc., and high-precision installation guidance is provided for underground pipeline manholes, electrical manholes, fire branch pipes, equipment rooms, etc. through transparency comparison.

[0039] The principles and effects of the above technical solution:

[0040] This construction method's AR software application consists of a web-based server and a mobile native system. Based on BIM modeling technology, it allows the model to be placed on the construction site. Written in HTML, the application resides in the browser of a smart mobile device, requiring no download or installation; simply open the application to use it – very convenient. Simultaneously, when users are guided through the virtual reality system, the model displays the relative positions of all installed pipelines, allowing them to see the distribution of pipelines and avoid collisions during actual installation. Using the AR model to guide pipeline construction on-site, AR technology can check pipeline dimensions, installation direction, installation positioning, and installation integrity. Transparency comparison provides high-precision installation guidance for underground pipeline manholes, electrical manholes, fire branch pipes, equipment rooms, etc., improving installation accuracy, reducing installation time lost due to incomplete installation, effectively shortening the construction cycle, and increasing construction efficiency. Because AR-guided installation allows for checking installation integrity, it also improves the quality of pipeline installation.

[0041] Example 2:

[0042] like Figures 1-4As shown, the present invention provides a pipe position detection and correction device, including several position detection and correction devices. Each position detection and correction device includes a detachable frame 1 for supporting and correcting pipe 16. The frame 1 includes an upper frame 11, a lower frame 12, a left frame 13, and a right frame 14. The upper frame 11 has cross grooves at both ends. The left frame 13 and the right frame 14 are slidably connected in the corresponding cross grooves by moving cylinders. The left frame 13 and the right frame 14 are both formed by upper and lower side plates engaging. The lower ends of the left frame 13 and the right frame 14 are both provided with square grooves. The two ends of the lower frame 12 are slidably connected horizontally in the square grooves. The lower surface of the upper frame 11 is provided with a first detector (not shown in the figure) for detecting the relative position of two vertical pipes 16. A moving unit 2 for moving the frame 1 is provided parallel to the upper frame 11. The moving unit 2 is rotatably connected to the upper frame 11. The upper surface of the moving unit 2 is provided with two suction cups 4 rotatably connected to the moving unit 2 by a first motor 3. The suction cups 4 are adsorbed onto the wall above the corresponding pipe 16. On the wall; when one of the suction cups 4 adheres to the wall, the first motor 3 can drive the moving unit 2 to rotate around the suction cup 4; a tilt correction unit 5 is provided on the lower frame 12; the tilt correction unit 5 includes two telescopic cylinders 51 vertically connected to the lower frame 12; an inverted T-shaped plate 52 parallel to the lower frame 12 is connected to the telescopic cylinder 51; a support block 53 for supporting the pipe 16 is rotatably connected to the vertical section of the inverted T-shaped plate 52; an arc parallel to the lower frame 12 is connected to the bottom of the support block 53. A toothed ring 54; a second motor (not shown in the figure) is vertically connected to the front and rear direction of the vertical section of the inverted T-shaped plate 52; the power end of the second motor is coaxially connected to an adjusting gear 55 that meshes with the arc-shaped toothed ring 54; both ends of the inverted T-shaped plate 52 and the support block 53 have gaps with the left frame 13 and the right frame 14, so that when the support block 53 rotates, it will not collide with the left frame 13 and the right frame 14; the opposing side walls of the left frame 13 and the right frame 14 are provided with support units 6 that are telescopic and can support the side walls of the pipe 16; such as Figure 2 As shown, the pipes 16 are typically placed by setting two vertically connected rods 10 on the wall, connecting the fixing plate 15 to the connecting rods 10 with nuts, and then placing two adjacent pipes 16 on the corresponding fixing plate 15.

[0043] The principles and effects of the above technical solution:

[0044] like Figure 2As shown, after aligning the frame 1 parallel to the moving unit 2, the two suction cups 4 are attached to the area above the intersection of the two vertical pipes 16. The frame 1 is then placed over the vertical pipe 16, fixing the left suction cup 4 in place. After releasing the right suction cup 4, the first motor 3 on the left suction cup 4 is driven to rotate the moving unit 2 and the frame 1 counterclockwise around the left suction cup 4. Once the frame 1 reaches the horizontally positioned pipe 16, it passes through the pipe 16. During this process, the first detector can detect the arc length from A1 to A2, the arc length from B1 to B2, and whether the two pipes 16 are on the same plane. This is then compared with a pre-stored arc-shaped pipe 17 (e.g., ...). Figure 3 The corresponding values ​​(as shown) are compared, and then corrected using pipeline position detection and correction equipment. The process is as follows:

[0045] like Figure 1 As shown, before adjusting the pipe 16, two suction cups 4 are attached to the top of the pipe 16 to be adjusted, making the moving unit 2 parallel to the pipe 16. Then, the frame 1 is rotated to be perpendicular to the moving unit 2 through the moving unit 2, and then the frame 1 is slid through the moving unit 2 to fit over the pipe 16. Then, the adjustment begins. The telescopic cylinder 51 is activated to move upward, driving the inverted T-shaped plate 52 to move, so that the support block 53 supports the lower surface of the pipe 16, and the two support units 6 support the two side walls of the pipe 16. The second motor is driven to rotate, and the arc-shaped gear ring 54 is rotated through the adjusting gear 55, thereby driving the support block 53 to rotate and adjust the inclination of the pipe 16. Since the support unit 6 can extend and retract, as the inclination of the pipe 16 is corrected, the support unit 6 extends or retracts accordingly, thereby supporting the side walls of the pipe 16. When the correction is reached to the required position, the second motor is stopped, and the fixing plate 15 is adjusted with the nut to fit against the lower surface of the pipe 16, thus completing the correction of the inclination of the pipe 16.

[0046] The two suction cups 4 cooperate with the first motor 3 to rotate at the corner of the two perpendicular pipes 16, so that the first detector on the frame 1 can complete the arc movement, thereby better detecting the arc length and facilitating comparison with the arc pipe 17; at the same time, the moving unit 2 is rotatably connected to the frame 1, and the moving unit 2 can be adjusted to be perpendicular to the frame 1. Then, the relative distance between the frame 1 and the pipe 16 can be adjusted through the moving unit 2, thereby facilitating the subsequent adjustment of the inclination of the pipe 16.

[0047] In this embodiment, as Figure 1As shown, a groove is formed on the upper surface of the support block 53; a slider 18 is slidably connected in the groove; the upper surface of the slider 18 is higher than the support block 53; a through groove (not shown in the figure) is formed at the bottom of the support block 53 near the right end of the support block 53; a rotating gear (not shown in the figure) is rotatably connected to the front and rear side walls of the through groove via a third motor (not shown in the figure); a toothed plate (not shown in the figure) meshes with the rotating gear at the bottom of the slider 18; a second detector (not shown in the figure) for detecting the parallelism of the pipe 16 is also provided on the inner side wall of the left frame 13; the second detector is located above the support unit 6.

[0048] The principles and effects of the above technical solution:

[0049] Even if the arc lengths from A1 to A2 and from B1 to B2 of the two vertical pipes 16 meet the installation requirements of the curved pipe 17, it does not mean that the other end of the pipe 16 has not shifted in the left or right direction. In order to detect whether the pipe 16 has shifted in the left or right direction and how to correct the shifted pipe 16, two suction cups 4 are attached to the pipe 16 to be adjusted, so that the moving unit 2 is parallel to the pipe 16. Then, the frame 1 is rotated to be perpendicular to the moving unit 2. Then, the frame 1 is slid by the moving unit 2 so that the frame 1 fits over the pipe 16. The moving unit 2 drives the frame 1 to move along the length of the pipe 16. The second detector is used to detect the pipe 16. If a deviation occurs in the left or right direction, the telescopic cylinder 51 drives the inverted T-shaped plate 52 to move upward, thereby driving the slider 18 on the support block 53 to support the lower surface of the pipe 16. The third motor drives the rotating gear to rotate, and the toothed plate drives the slider 18 to move left and right, completing the adjustment of the left and right position of the pipe 16. Then the telescopic shaft of the telescopic cylinder 51 is retracted. The fixed plate 15 supports the pipe 16 and cooperates with the arc-shaped toothed ring 54 and the adjusting gear 55 on the second motor. When the pipe 16 has both tilt deviation and left and right deviation, the tilt and deviation of the pipe 16 can be corrected at the same time, improving the correction efficiency.

[0050] In this embodiment, as Figure 4 As shown, the moving unit 2 includes a track 21 parallel to the upper frame 11, and a pulley 22 that is rolled on the track 21; a fourth motor 23 is vertically connected below the pulley 22; the power end of the fourth motor 23 is fixedly connected to the upper frame 1; a circular groove 7 is opened on the track 21; two suction cups 4 are vertically coaxially connected to the circular groove 7 and rotatably connected to the track 21; an internal gear ring (not shown in the figure) is coaxially provided in the circular groove 7; a first motor 3 is connected to the side wall of the suction cup 4; a rotating gear 8 that meshes with the internal gear ring is coaxially connected to the power end of the first motor 3.

[0051] The principles and effects of the above technical solution:

[0052] Before adjusting the position of pipe 16, two suction cups 4 are attached to the pipe 16 to be adjusted, so that the track 21 is parallel to the pipe 16. Then, the fourth motor 23 rotates, thereby driving the frame 1 to rotate perpendicular to the track 21. The frame 1 slides on the track 21 through the pulley 22, thereby driving the frame 1 to fit over the pipe 16, completing the equipment debugging before adjusting the pipe 16. The track 21 allows the frame 1 to adjust its relative position to the pipe 16, making it convenient to use.

[0053] In this embodiment, as Figure 1 As shown, there are two support units 6, and the two support units 6 are respectively set on the opposing side walls of the left frame 13 and the right frame 14. The opposing side walls of the left frame 13 and the right frame 14 are both provided with grooves. Each support unit 6 includes a sleeve 61 rotatably connected to the front and rear side walls of the groove. A sleeve rod 62 is slidably connected inside the sleeve 61 by a spring. A clamping block 63 for supporting the side wall of the pipe 16 is rotatably connected to the end of the sleeve rod 62 away from the groove.

[0054] The principles and effects of the above technical solution:

[0055] The sleeve rod 62 is set inside the sleeve 61 by a spring. Through the elastic deformation of the spring, it can cooperate with the abutment block 63 on the rotatable connecting sleeve rod 62 to fit and support the side wall of the pipe 16 well.

[0056] In this embodiment, both ends of the lower frame 12 are provided with blocks 9, which can prevent the left frame 13 and the right frame 14 from sliding out of the square groove.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
