Description

Technical Field

[0001] The present application relates to the technical field of curtain wall flatness detection, and in particular to a device for detecting the flatness of a building curtain wall. Background Art

[0002] The flatness test of building curtain walls primarily examines the smoothness of the curtain wall surface, specifically the difference between the linear length of the curtain wall components and the corresponding wheelbase. Flatness significantly impacts the appearance, installation, and construction equipment of the curtain wall, making it a crucial parameter in curtain wall inspection. Flatness testing typically utilizes specialized tools or instruments, such as feeler gauges and laser rangefinders, to measure parameters such as gaps and deflection, thereby assessing the curtain wall's smoothness. If the smoothness does not meet requirements, measures may be necessary to ensure the quality and performance of the curtain wall.

[0003] In the prior art, the common method for testing the flatness of building curtain walls is for inspectors to sit on a crane and hold a measuring device, a ruler, against the building's curtain wall to perform the flatness test. Manual testing of the curtain walls of modern high-rise buildings is complex and prone to human error. Therefore, there is an urgent need for a device that can accurately and effectively test curtain wall flatness. Summary of the Invention

[0023] 1. A rotary motor drives the rotating wheel, which in turn drives the movable base to rise and fall along the suspension rope. The movable base automatically moves to the curtain wall position requiring inspection. The rotating motor stops, and the suspension rope is locked via the locking assembly to prevent the movable base from sliding downward. The adsorption motor then starts, driving the impeller to rotate, causing the air in the adsorption chamber to be discharged through the air outlet. The sealing element contacts the curtain wall surface, causing the adsorption disc to adhere to the curtain wall and prevent the movable base from shifting or shaking. The detection element on the detection arm then detects the flatness of the curtain wall.

Furthermore, because the inspection arm is equipped with several inspection rods along its length, it can inspect the flatness of the curtain wall's lengthwise (vertical) direction. During the inspection process, a telescopic cylinder drives the movable arm to slide, moving the inspection arm along the curtain wall's widthwise (horizontal) direction, thereby inspecting the curtain wall's widthwise (horizontal) flatness. This completes the inspection of the entire curtain wall's horizontal and horizontal flatness, improving inspection quality and efficiency.

[0025] 3. The angle between the two mounting arms is adjustable through an adjustment mechanism to accommodate curved curtain walls of varying curvatures. During testing, as the detection arm moves toward the movable base, the detection rod remains perpendicular to the curtain wall surface, ensuring the rod extends uniformly and facilitating smooth movement.

[0041] The embodiment of the present application discloses a device for detecting the flatness of a building curtain wall.

[0042] Reference Figure 1 and Figure 2 A device for detecting the flatness of a building curtain wall comprises a suspension rope 1, a movable base 2, a mounting arm 3, a detection arm 4, and a negative pressure adsorption assembly 5. The negative pressure adsorption assembly 5 is disposed at the bottom of the movable base 2 for adsorption onto the curtain wall. One end of the suspension rope 1 is fixedly mounted on the top of the building curtain wall, while the other end extends downward along the curtain wall. The movable base 2 is connected to the suspension rope 1 and is provided with a traveling mechanism 6 for moving along the suspension rope 1. The traveling mechanism 6 drives the movable base 2 to move along the suspension rope 1, thereby enabling detection of curtain walls at different heights.

[0043] Reference Figure 1 and Figure 3 The mounting arms 3 are provided on both sides of the movable base 2, and one end of the mounting arms 3 is connected to the movable base 2. The detection arm 4 is provided on the mounting arm 3, and a detection rod 41 is slidably provided on the detection arm 4. A plurality of detection rods 41 are provided at intervals along the length direction of the detection arm 4, and a detection element 411 is provided on the detection arm 4.

[0044] Among them, reference Figure 1 and Figure 3The mounting arm 3 includes a fixed arm 31 and a movable arm 32. The movable arm 32 is slidably mounted on the fixed arm 31. The movable arm 32 is provided with a driving source for driving the movable arm 32 to slide along the length direction of the fixed arm 31. The driving source is a telescopic cylinder 321. The telescopic cylinder 321 is fixedly arranged on the movable arm 32 along the length direction of the movable arm 32. The piston rod of the telescopic cylinder 321 is fixedly connected to the fixed arm 31.

[0045] The drive source drives the movable arm 32 to extend and retract along the fixed arm 31, thereby adjusting the spacing between the two detection arms 4 to accommodate curtain walls of varying widths. Furthermore, because the detection arm 4 is provided with a plurality of detection rods 41 along its length, it can detect the flatness of the curtain wall along its length (vertical direction). During the detection process, the telescopic cylinder 321 drives the movable arm 32 to slide, thereby moving the detection arm 4 along the width of the curtain wall, thereby detecting the flatness of the curtain wall along its width (horizontal direction). This completes the horizontal and vertical flatness detection of the entire curtain wall, improving the quality and efficiency of the inspection.

[0046] Optionally, refer to Figure 1 and Figure 3The detection rod 41 slides through the detection arm 4, and the top of the detection rod 41 extends outside the detection arm 4. To minimize damage to the curtain wall, a ball 412 is rolled and embedded in the bottom of the detection rod 41. The ball 412 is used to contact the curtain wall surface. The detection rod 41 is sleeved with a spring 414, and the bottom of the detection rod 41 is provided with a step 413. One end of the spring 414 is fixedly connected to the detection arm 4, and the other end is fixedly connected to the step 413. The spring 414 drives the detection rod 41 to press against the curtain wall. The side wall of the detection rod 41 is evenly spaced with multiple detection teeth 415. The detection element 411 can be a laser sensor. In this embodiment, a laser sensor is provided at each end of the detection arm 4. The two laser sensors are arranged at a height offset from each other. The vertical spacing between the two laser sensors is equal to the spacing between adjacent detection teeth 415. In the initial state, the laser emitted by one laser sensor is located in the gap between two adjacent detection teeth 415, and the other laser sensor is located at the detection tooth 415. When detecting the curtain wall, under the action of the spring 414, the ball 412 contacts the surface of the curtain wall. If the curtain wall surface is flat, the length of each detection rod 41 extending above the detection arm 4 is the same, that is, the projection of the detection teeth 415 on each detection rod 41 in the length direction of the detection arm 4 coincides, then one of the laser sensors will pass through all the detection rods 41. If the curtain wall surface is uneven, then some detection rods 41 will move up or down, then the detection teeth 415 on the detection rod 41 will be misaligned with the detection teeth 415 on other detection rods 41, and the misaligned detection teeth 415 will block the laser beam emitted by the laser sensor, resulting in different detection results, and then it can be known that the curtain wall is uneven. The present application uses two laser sensors to detect the flatness of the curtain wall within the entire length range of the detection arm 4, reducing the number of laser sensors and reducing maintenance costs.

[0047] Optional, see Figure 1 and Figure 4A mounting platform 21 is fixedly provided on the top of the movable seat 2, and the mounting arm 3 is rotatably provided in the mounting platform 21. The mounting platform 21 is provided with an adjustment mechanism for adjusting the angle between the two mounting arms 3. Specifically, the adjustment mechanism includes a sector gear 71, an adjustment gear 72 and a rotating assembly. The sector gear 71 is fixedly provided at one end of the fixed arm 31, and an ear plate 22 is fixedly provided on the movable seat 2. The fixed arm 31 is hinged on the ear plate 22. The adjustment gear 72 is rotatably provided on the movable seat 2, and the rotation plane of the adjustment gear 72 is perpendicular to the surface of the movable seat 2. The adjustment gear 72 is engaged with the two sector gears 71 to drive the two sector gears 71 to deflect perpendicular to the surface of the movable seat 2, that is, perpendicular to the surface of the curtain wall, thereby adjusting the angle between the two mounting arms 3 to adapt to curved curtain walls of different curvatures. During the detection process, when the detection arm 4 moves toward the movable seat 2, the detection rod 41 is always perpendicular to the surface of the curtain wall, ensuring that the length of the extension of the detection rod 41 is equal, which facilitates the smooth movement of the detection rod 41.

[0048] Among them, reference Figure 4 The rotating assembly includes a worm gear 731, a worm 732, and an adjustment motor 733. The worm gear 731 and worm 732 are rotatably mounted within the mounting platform 21. The worm gear 731 is coaxially fixedly connected to the adjustment gear 72, and the worm 732 meshes with the worm gear 731. The adjustment motor 733 is fixedly mounted within the mounting platform 21, and the output shaft of the adjustment motor 733 is fixedly connected to the worm 732. The adjustment motor 733 is a servo motor. The rotation of the adjustment motor 733 drives the worm 732, which in turn drives the worm gear 731. The worm gear 731 drives the adjustment gear 72, which in turn drives the sector gear 71, thereby driving the deflection angle of the mounting arm 3. The worm gear 731 cooperates with the worm 732 to limit the position of the mounting arm 3 when the adjustment motor 733 stops operating.

[0049] Optional, see Figure 5 and Figure 6The walking mechanism 6 includes a guide rail 61, a wheel 62, and a driving member. In this embodiment, two walking mechanisms 6 are provided along the length direction of the movable seat 2, that is, two are distributed along the length direction of the suspension rope 1. A mounting plate 23 is fixedly provided on the top wall of the movable seat 2, and the mounting plate 23 is perpendicular to the movable seat 2. The guide rail 61 is provided on the mounting plate 23 along the length direction of the suspension rope 1, and the wheel 62 is rotatably provided on the mounting plate 23. There is a gap between the guide rail 61 and the wheel 62 for the suspension rope 1 to pass through, and the gap is smaller than the diameter of the suspension rope 1, so that the friction between the wheel 62 and the suspension rope 1 is greater than the gravity of the movable seat 2. The driving member is used to drive the wheel 62 to rotate. The driving member is a rotary motor 63. The rotary motor 63 is fixedly provided on the mounting plate 23, and the output shaft of the rotary motor 63 is fixedly connected to the wheel 62. When the curtain wall needs to be inspected, the rotary motor 63 drives the wheel 62 to rotate, and the wheel 62 drives the movable seat 2 to rise and fall along the suspension rope 1, realizing automatic movement to the curtain wall position that needs to be inspected without the need for workers to ride in a hanging basket.

[0050] Reference Figure 5 and Figure 6 The guide rail 61 is slidably mounted on the mounting plate 23. The mounting plate 23 is provided with an adjustment member for adjusting the distance between the guide rail 61 and the rotating wheel 62. Specifically, a dovetail groove 231 is defined along the length of the mounting plate 23. A dovetail block 611 is fixedly mounted on the guide rail 61 and slidably engages with the dovetail groove 231. To prevent the suspension rope 1 from escaping from the guide rail 61, a retaining groove 612 is defined along the length of the suspension rope 1 on the sidewall of the guide rail 61 near the rotating wheel 62. The suspension rope 1 is threaded into the retaining groove 612. The adjusting part is an adjusting screw 232, which is threaded into the mounting plate 23, and the adjusting screw 232 is ball-connected with the dovetail block 611. By rotating the adjusting screw 232, the guide rail 61 is driven to slide along the dovetail groove 231, thereby achieving the purpose of adjusting the distance between the guide rail 61 and the rotating wheel 62, which is convenient for installing or removing the lifting rope 1. When the lifting rope 1 needs to be removed, it is only necessary to move the guide rail 61 upwards so that the lifting rope 1 can be taken out from one side of the guide rail 61, which is easy to operate.

[0051] Furthermore, a locking groove 613 is provided on the guide rail 61, and a locking groove 613 is provided at both ends of each guide rail 61. A locking assembly for tightening the sling 1 in the locking groove 613 is provided on the mounting plate 23. The locking assembly includes an abutment column 81, a drive frame 82 and a locking cylinder 83. The locking cylinder 83 is fixedly arranged on the mounting plate 23 along the length direction of the mounting plate 23. The drive frame 82 is fixedly arranged on the piston rod of the locking cylinder 83, and the abutment column 81 is fixedly arranged on the drive frame 82. When the movable base 2 moves to the position to be tested, the locking frame is driven upward by the locking cylinder 83, driving the two abutment columns 81 to move upward synchronously, thereby tightening the sling 1 in the locking groove 613, preventing the movable base 2 from sliding downward, and ensuring the stability of the position of the movable base 2.

[0052] In this embodiment, refer to Figure 4 The side wall of the mobile seat 2 is provided with a rolling part, and the rolling part is provided with four groups. The rolling part includes a lifting cylinder 24 and a roller 241. The lifting cylinder 24 is fixedly provided on the side wall of the mobile seat 2 in a direction perpendicular to the mobile seat 2, that is, the lifting cylinder 24 is perpendicular to the surface of the curtain wall, and the piston rod of the lifting cylinder 24 is rotatably provided with a roller 241. In the process of the mobile seat 2 being lifted and lowered along the suspension rope 1, the lifting cylinder 24 drives the roller 241 to move toward the direction close to the curtain wall, so that the mobile seat 2 is lifted, that is, the negative pressure adsorption component 5 is separated from the contact with the curtain wall, preventing the negative pressure adsorption component 5 from being worn. At the same time, the roller 241 is in rolling contact with the curtain wall, which plays a certain role in limiting the mobile seat 2, preventing the mobile seat 2 from shaking, and ensuring that the mobile seat 2 moves along the length direction of the suspension rope 1. After the mobile seat 2 moves to the position to be tested, the lifting cylinder 24 is shortened, shortening the distance between the mobile seat 2 and the curtain wall surface, so that the negative pressure adsorption component 5 can work smoothly.

[0053] Optional, see Figure 7 and Figure 8 The negative pressure adsorption assembly 5 includes an adsorption plate 51, an impeller 52, an adsorption motor 53, and a sealing element 54. The adsorption plate 51 is fixedly mounted on the bottom wall of the movable base 2. The adsorption plate 51 has an adsorption chamber. The cross section of the adsorption plate 51 is circular. An air outlet is provided at the top of the adsorption plate 51. The end of the adsorption plate 51 away from the movable base 2 is open. The sealing element 54 is disposed at the end of the adsorption plate 51 away from the movable base 2 for contact with the surface of the curtain wall. In this embodiment, the sealing element 54 can be a rubber sealing ring having a circular ring structure. The impeller 52 is rotatably mounted in the adsorption plate 51. The adsorption motor 53 is disposed on the adsorption plate 51 for driving the impeller 52 to rotate. During operation, when the movable base 2 is raised or lowered to the position of the curtain wall to be measured, the adsorption motor 53 is started, and the adsorption motor 53 drives the impeller 52 to rotate, so that the air in the adsorption chamber is discharged from the air outlet, and the sealing element 54 abuts against the surface of the curtain wall, so that the adsorption plate 51 is adsorbed on the curtain wall, which stabilizes the movable base 2 and prevents the movable base 2 from shifting or shaking.

[0054] Optional, see Figure 1 and Figure 8 Two air outlet pipes 511 are connected to the adsorption disc 51, and a cleaning pipe 42 is fixedly installed on the detection arm 4. The cleaning pipe 42 extends along the length of the detection arm 4. The cleaning pipe 42 has an air outlet hole near the side wall of the curtain wall, and the air outlet hole is connected to the air nozzle 421. The air outlet pipe 511 is connected to the cleaning pipe 42. During the detection process, the negative pressure adsorption component 5 is in operation. The gas in the adsorption disc 51 enters the cleaning pipe 42 through the air outlet pipe 511 and is discharged from the air nozzle 421, thereby achieving the purpose of cleaning dust and water stains on the curtain wall surface and improving the quality of the detection. The air outlet pipe 511 is directly connected to the adsorption disc 51, eliminating the need for a separate air source and simplifying the structure.

[0055] Reference Figure 9 and Figure 10 The negative pressure adsorption component 5 also includes an auxiliary sealing component 9, which includes a sealing strip 91 and a driving component. A plurality of sealing strips 91 are arranged in a circumferential array along the adsorption disk 51. The sealing strip 91 is an arc-shaped structure, and the driving component is used to drive the sealing strip 91 to move axially along the adsorption disk 51.

[0056] Specifically, refer to Figure 9 and Figure 10 The driving assembly includes a driving rod 92, an elastic member 93, a pull rope 94, a sleeve 95 and a winding assembly 96. The sleeve 95 is vertically fixed on the side wall of the adsorption disk 51. The driving rod 92 is slidably inserted into the sleeve 95. The sealing strip 91 is fixedly connected to the bottom wall of the driving rod 92. In this embodiment, the sealing strip 91 is made of rubber. The bottom end of the sealing strip 91 is provided with an extension portion 911, which extends outward and has a certain deformation compensation capability.

[0057] The elastic member 93 is used to drive the driving rod 92 to move downward. One end of the pull rope 94 is fixedly connected to the top of the driving rod 92. The elastic member 93 is a compression spring. One end of the compression spring abuts against the bottom wall of the sleeve 95, and the other end abuts against the sealing strip 91.

[0058] When testing a curved curtain wall, a gap between the sealing element 54 and the curtain wall becomes difficult to seal. The sealing strip 91 is then driven downward, contacting the curtain wall surface. The extension 911 compensates for the gap between the curved curtain wall and the sealing element 54, enhancing the seal and ensuring that the adsorption plate 51 remains firmly attached to the curtain wall, enabling testing on the curved surface. When testing a flat curtain wall, the pull cord 94 is driven upward by the winding assembly 96, pulling the drive rod 92 upward, disengaging the sealing strip 91 from the curtain wall. This prevents an overly tight seal from preventing gas from entering the adsorption plate 51 and affecting the cleaning effect of the cleaning tube 42.

[0059] Reference Figure 9 and Figure 10The winding assembly 96 is used to reel in the drawstring 94. The winding assembly 96 includes a drive gear 961, a gear ring 962, a winding wheel 963, and a drive motor 964. The gear ring 962 and the winding wheel 963 are rotatably mounted on the suction plate 51, and the gear ring 962 and the winding wheel 963 are fixedly connected. The drawstring 94 is fixedly connected to the winding wheel 963. The drive motor 964 is fixedly mounted on the suction plate 51. The drive gear 961 is fixedly mounted on the output shaft of the drive motor 964, and the drive gear 961 meshes with the gear ring 962. The drive motor 964 drives the drive gear 961 to rotate, and the drive gear 961 drives the gear ring 962 and the winding wheel 963 to rotate, driving the drawstring 94 to move upward, thereby driving the sealing strip 91 to move upward.

[0060] The implementation principle of the embodiment of the present application is as follows: first, fix the suspension rope 1 on the top of the curtain wall, and extend the suspension rope 1 downward along the height direction of the curtain wall. The rotary motor 63 drives the rotating wheel 62 to rotate, and the rotating wheel 62 drives the movable seat 2 to rise and fall along the suspension rope 1. The movable seat 2 automatically moves to the curtain wall position that needs to be detected. The rotary motor 63 stops working, and the suspension rope 1 is locked by the locking assembly to prevent the movable seat 2 from sliding downward. At this time, the adsorption motor 53 is started, and the adsorption motor 53 drives the impeller 52 to rotate, so that the air in the adsorption chamber is discharged from the air outlet, and the sealing element 54 abuts against the surface of the curtain wall, so that the adsorption plate 51 is adsorbed on the curtain wall, which serves the purpose of stabilizing the movable seat 2 and preventing the movable seat 2 from shifting or shaking.

[0061] Then unfold the mounting arm 3, move the two detection arms 4 to the position to be detected, and the detection arms 4 are vertically distributed. During detection, under the action of the spring 414, the ball 412 contacts the surface of the curtain wall. If the surface of the curtain wall is flat, the length of each detection rod 41 extending above the detection arm 4 is the same, that is, the projection of the detection teeth 415 on each detection rod 41 in the length direction of the detection arm 4 coincides, then one of the laser sensors will pass through all the detection rods 41, and if the surface of the curtain wall is uneven, then some detection rods 41 will move up or down, then the detection teeth 415 on the detection rod 41 will be misaligned with the detection teeth 415 on other detection rods 41, and the misaligned detection teeth 415 will block the laser beam emitted by the laser sensor, resulting in different detection results, and then it can be known that the curtain wall is uneven. The present application uses two laser sensors to detect the flatness of the curtain wall within the entire length range of the detection arm 4, reducing the number of laser sensors and reducing maintenance costs.

[0062] During the inspection process, a drive source drives the movable arm 32 to extend and retract along the fixed arm 31, thereby adjusting the spacing between the two inspection arms 4 to accommodate curtain walls of varying widths. Furthermore, because the inspection arm 4 is provided with a plurality of inspection rods 41 along its length, it can detect the flatness of the curtain wall along its length (vertical direction). During the inspection process, the telescopic cylinder 321 drives the movable arm 32 to slide, thereby moving the inspection arm 4 along the width of the curtain wall, thereby detecting the flatness of the curtain wall along its width (horizontal direction). This completes the inspection of the horizontal and vertical flatness of the entire curtain wall, improving the quality and efficiency of the inspection.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
