[0024] The embodiment of the present application discloses a device for detecting the flatness of a building curtain wall.

[0025] Reference Figure 1 and Figure 2 A device for detecting the flatness of a building curtain wall comprises a suspension rope 1, a moving seat 2, a mounting arm 3, a detection arm 4 and a negative pressure adsorption component 5, wherein the negative pressure adsorption component 5 is arranged at the bottom of the moving seat 2 for adsorption on the curtain wall. One end of the suspension rope 1 is fixedly arranged at the top of the building curtain wall, and the other end extends downward along the curtain wall. The moving seat 2 is connected to the suspension rope 1, and a walking mechanism 6 for moving along the suspension rope 1 is arranged on the moving seat 2; the walking mechanism 6 drives the moving seat 2 to move along the suspension rope 1, thereby realizing the detection of curtain walls at different heights.

[0026] Reference Figure 1 and Figure 3 The mounting arms 3 are arranged on both sides of the moving base 2, and one end of the mounting arms 3 is connected to the moving base 2. The detection arm 4 is arranged on the mounting arm 3, and a detection rod 41 is slidably arranged on the detection arm 4. A plurality of detection rods 41 are arranged at intervals along the length direction of the detection arm 4, and a detection element 411 is arranged on the detection arm 4.

[0027] Among them, refer to 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.

[0028] The movable arm 32 is driven by the driving source to extend and retract along the fixed arm 31, thereby adjusting the distance between the two detection arms 4 to adapt to curtain walls of different sizes and widths. In addition, since a number of detection rods 41 are distributed along the length direction of the detection arm 4, the flatness of the curtain wall in the length direction (vertical direction) can be detected; during the detection process, the telescopic cylinder 321 drives the movable arm 32 to slide, so as to drive the detection arm 4 to move along the width direction of the curtain wall, thereby detecting the flatness of the curtain wall in the width direction (horizontal direction); thereby completing the detection of the horizontal and vertical flatness of the entire curtain wall, and improving the quality and efficiency of the detection.

[0029] Optionally, refer to Figure 1 and Figure 3, the detection rod 41 is slidably arranged in the detection arm 4, and the top of the detection rod 41 extends out of the detection arm 4. In order to reduce the damage to the curtain wall, the bottom of the detection rod 41 is rollingly embedded with a ball 412, and the ball 412 is used to contact the surface of the curtain wall. A spring 414 is sleeved on the detection rod 41, and a step 413 is arranged at the bottom of the detection rod 41. 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 a plurality of detection teeth 415. The detection element 411 can be a laser sensor. In this embodiment, a laser sensor is respectively arranged at both ends of the detection arm 4. The height positions of the two laser sensors are staggered up and down, and the spacing between the two laser sensors in the vertical direction is equal to the spacing between the two adjacent detection teeth 415; so that in the initial state, the laser emitted by one of the laser sensors is located at the gap between the 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 abuts against 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.

[0030] Optional, see Figure 1 and Figure 4, a mounting platform 21 is fixedly provided on the top of the moving seat 2, the mounting arm 3 is rotatably provided in the mounting platform 21, and 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, an ear plate 22 is fixedly provided on the moving seat 2, the fixed arm 31 is hinged on the ear plate 22, the adjustment gear 72 is rotatably provided on the moving seat 2, and the rotation plane of the adjustment gear 72 is perpendicular to the surface of the moving seat 2, the adjustment gear 72 is meshed with the two sector gears 71, and is used to drive the two sector gears 71 to deflect on the surface perpendicular to the moving 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 moving seat 2, the detection rod 41 is always perpendicular to the surface of the curtain wall, ensuring that the elongated length of the detection rod 41 is equal, so as to facilitate the smooth movement of the detection rod 41.

[0031] Among them, refer to Figure 4 The rotating assembly includes a worm wheel 731, a worm 732 and an adjusting motor 733. The worm wheel 731 and the worm 732 are rotatably arranged in the mounting platform 21. The worm wheel 731 is coaxially fixedly connected with the adjusting gear 72. The worm 732 is meshed with the worm wheel 731. The adjusting motor 733 is fixedly arranged in the mounting platform 21. The output shaft of the adjusting motor 733 is fixedly connected with the worm 732. The adjusting motor 733 is a servo motor. The adjusting motor 733 rotates to drive the worm 732 to rotate. The worm 732 drives the worm wheel 731 to rotate. The worm wheel 731 drives the adjusting gear 72 to rotate, thereby driving the sector gear 71 to rotate, thereby driving the deflection angle of the mounting arm 3. The worm wheel 731 cooperates with the worm 732. When the adjusting motor 733 stops working, it serves the purpose of limiting the position of the mounting arm 3.

[0032] Optional, see Figure 5 and Figure 6The walking mechanism 6 includes a guide rail 61, a rotating wheel 62 and a driving member. In this embodiment, two walking mechanisms 6 are arranged along the length direction of the moving seat 2, that is, two are distributed along the length direction of the suspension rope 1. The top wall of the moving seat 2 is fixedly provided with a mounting plate 23, and the mounting plate 23 is perpendicular to the moving seat 2. The guide rail 61 is arranged on the mounting plate 23 along the length direction of the suspension rope 1, and the rotating wheel 62 is rotatably arranged on the mounting plate 23. There is a gap between the guide rail 61 and the rotating 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 rotating wheel 62 and the suspension rope 1 is greater than the gravity of the moving seat 2. The driving member is used to drive the rotating wheel 62 to rotate, and the driving member is a rotating motor 63, which is fixedly arranged on the mounting plate 23, and the output shaft of the rotating motor 63 is fixedly connected to the rotating wheel 62. When the curtain wall needs to be inspected, the rotating motor 63 drives the rotating wheel 62 to rotate, and the rotating wheel 62 drives the moving seat 2 to rise and fall along the suspension rope 1, so as to realize automatic movement to the curtain wall position that needs to be inspected, without the need for workers to ride in the hanging basket.

[0033] Reference Figure 5 and Figure 6 The guide rail 61 is slidably disposed on the mounting plate 23, and an adjusting member for adjusting the distance between the guide rail 61 and the rotating wheel 62 is disposed on the mounting plate 23. Specifically, a dovetail groove 231 is provided in the length direction of the mounting plate 23, and a dovetail block 611 is fixedly disposed on the guide rail 61, and the dovetail block 611 is slidably connected to the dovetail groove 231. In order to prevent the suspension rope 1 from escaping from the guide rail 61, a limiting groove 612 is provided on the side wall of the guide rail 61 close to the rotating wheel 62 along the length direction of the suspension rope 1, and the suspension rope 1 is inserted into the limiting groove 612. The adjusting member is an adjusting screw 232, which is threadedly inserted into the mounting plate 23, and is ball-connected to 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.

[0034] 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 pressing the suspension rope 1 against the locking groove 613 is provided on the mounting plate 23. The locking assembly includes an abutment column 81, a driving 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 driving frame 82 is fixedly arranged on the piston rod of the locking cylinder 83, and the abutment column 81 is fixedly arranged on the driving frame 82. When the moving seat 2 moves to the position to be measured, the locking frame is driven by the locking cylinder 83 to move upward, driving the two abutment columns 81 to move upward synchronously, thereby pressing the suspension rope 1 against the locking groove 613, preventing the moving seat 2 from sliding downward, and ensuring the stability of the position of the moving seat 2.

[0035] In this embodiment, refer to Figure 4 The side wall of the moving 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 moving seat 2 in a direction perpendicular to the moving 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 moving 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 moving seat 2 is lifted, that is, the negative pressure adsorption component 5 is separated from the contact with the curtain wall, and the negative pressure adsorption component 5 is prevented 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 moving seat 2, preventing the moving seat 2 from shaking, and ensuring that the moving seat 2 moves along the length direction of the suspension rope 1. After the moving seat 2 moves to the position to be measured, the lifting cylinder 24 is shortened, shortening the distance between the moving seat 2 and the surface of the curtain wall, so that the negative pressure adsorption component 5 can work smoothly.

[0036] 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 arranged on the bottom wall of the movable seat 2. The adsorption plate 51 has an adsorption cavity. The cross section of the adsorption plate 51 is circular. An air outlet is provided on the top of the adsorption plate 51. The adsorption plate 51 is opened at one end away from the movable seat 2. The sealing element 54 is arranged at one end of the adsorption plate 51 away from the movable seat 2 for fitting with the surface of the curtain wall. In this embodiment, the sealing element 54 can be a rubber sealing ring with a circular ring structure. The impeller 52 is rotatably arranged in the adsorption plate 51. The adsorption motor 53 is arranged on the adsorption plate 51 for driving the impeller 52 to rotate. During operation, when the movable seat 2 is lifted 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 seat 2 and prevents the movable seat 2 from shifting or shaking.

[0037] 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 arranged on the detection arm 4. The cleaning pipe 42 extends along the length direction of the detection arm 4, and an air outlet hole is opened on the side wall of the cleaning pipe 42 close to the curtain wall. The air outlet hole is connected to the air nozzle 421, and the air outlet pipe 511 is connected to the cleaning pipe 42. During the detection process, the negative pressure adsorption component 5 is in a working state, and the gas in the adsorption disc 51 enters the cleaning pipe 42 from the air outlet pipe 511 and is discharged from the air nozzle 421, thereby achieving the purpose of cleaning the dust and water stains on the surface of the curtain wall and improving the quality of the detection. And the air outlet pipe 511 is directly connected to the adsorption disc 51, and there is no need to set up a separate air source, which simplifies the structure.

[0038] Reference Fig. 9 and Fig.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. The driving component is used to drive the sealing strip 91 to move axially along the adsorption disk 51.

[0039] Specifically, refer to Fig. 9 and Fig.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.

[0040] 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.

[0041] When it is necessary to inspect a curved curtain wall, there is a gap between the sealing element 54 and the curtain wall that is difficult to seal; at this time, the sealing strip 91 is driven downward to make the sealing strip 91 contact the surface of the curtain wall, and the extension part 911 serves to compensate for the gap between the curved curtain wall and the sealing element 54, thereby increasing the sealing performance and ensuring that the adsorption plate 51 is firmly adsorbed on the curtain wall so that inspection can be performed on the curved curtain wall. When inspecting on a flat curtain wall, the pull rope 94 is driven upward by the winding assembly 96, and the driving rod 92 is pulled upward to make the sealing strip 91 break away from the contact with the curtain wall, thereby avoiding the seal being too tight and making it difficult for gas to enter the adsorption plate 51, thereby affecting the cleaning effect of the cleaning tube 42.

[0042] Reference Fig. 9 and Fig.10The winding assembly 96 is used to wind up the pull rope 94. The winding assembly 96 includes a driving gear 961, a gear ring 962, a winding wheel 963 and a driving motor 964. The gear ring 962 and the winding wheel 963 are rotatably sleeved on the adsorption disk 51, and the gear ring 962 and the winding wheel 963 are fixedly connected. The pull rope 94 is fixedly connected to the winding wheel 963. The driving motor 964 is fixedly set on the adsorption disk 51. The driving gear 961 is fixedly set on the output shaft of the driving motor 964, and the driving gear 961 is meshed with the gear ring 962. The driving motor 964 drives the driving gear 961 to rotate, and the driving gear 961 drives the gear ring 962 and the winding wheel 963 to rotate, driving the pull rope 94 to move upward, thereby driving the sealing strip 91 to move upward.

[0043] 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 the suspension rope 1 extends downward along the height direction of the curtain wall. The rotating motor 63 drives the rotating wheel 62 to rotate, and the rotating wheel 62 drives the moving seat 2 to rise and fall along the suspension rope 1. The moving seat 2 automatically moves to the curtain wall position that needs to be detected, and the rotating motor 63 stops working. The suspension rope 1 is locked by the locking assembly to prevent the moving 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 moving seat 2 and preventing the moving seat 2 from shifting or shaking.

[0044] 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 abuts against 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.

[0045] During the detection process, the driving source drives the movable arm 32 to extend and retract along the fixed arm 31, thereby adjusting the distance between the two detection arms 4 to adapt to curtain walls of different sizes and widths. In addition, since a number of detection rods 41 are distributed along the length direction of the detection arm 4, the flatness of the curtain wall in the length direction (vertical direction) can be detected; during the detection process, the telescopic cylinder 321 drives the movable arm 32 to slide, so as to drive the detection arm 4 to move along the width direction of the curtain wall, thereby detecting the flatness of the curtain wall in the width direction (horizontal direction); thereby completing the detection of the horizontal and vertical flatness of the entire curtain wall, and improving the quality and efficiency of the detection.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
