Description

Technical Field

[0001] The invention relates to the technical field of curtain wall detection, and in particular to a device for measuring the accuracy of a curved curtain wall and a working method thereof. Background Art

[0002] In order to improve the aesthetics of buildings, more and more buildings adopt spherical structures, in which the spherical building structure is composed of several curved curtain walls with equal curvature. In order to ensure the stability and sealing of the curved curtain wall installation, the thickness uniformity of the curved curtain wall needs to be tested before it is put into use. The thickness uniformity test can ensure the accuracy of the curtain wall and avoid stress concentration and structural instability caused by uneven thickness, thereby improving the safety and durability of the overall building. At the same time, the thickness uniformity test can also ensure the sealing between the curtain wall panels, prevent leakage, and ensure the waterproof and airtight performance of the building. In short, the thickness uniformity test is a key link in ensuring the quality and performance of the curved curtain wall of the spherical building, and is crucial to achieving the expected function and aesthetic effect of the building.

[0003] In the prior art, the detection of thickness uniformity of curved curtain walls is mainly divided into contact detection and non-contact detection. Contact detection uses traditional measuring tools such as calipers and micrometers to measure local thickness at multiple locations of the curtain wall panels, record data and compare them; non-contact detection mainly uses ultrasonic detection technology to measure the internal thickness of the curtain wall panels by transmitting and receiving ultrasonic signals. Although the above schemes can realize the uniformity detection of curved curtain wall thickness, they still have the following defects:

[0004] 1. Calipers and micrometers require manual point-by-point measurement, which is inefficient, and the measurement results are easily affected by human factors, with low accuracy and reliability;

[0005] 2. Ultrasonic testing usually requires the use of a coupling agent when testing the thickness of curtain walls. The use of a coupling agent increases the complexity and cost of testing. In addition, ultrasonic testing has certain limitations, especially for curtain wall panels made of multi-layer composite materials. The ultrasonic signal may be interfered with, resulting in unreliable measurement results. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-9 As shown, the present invention is a precision measuring device for curved curtain walls, comprising a lower arc seat 2 and an upper arc plate 3, wherein a plurality of telescopic members 4 for preventing the curved curtain wall 1 from tipping over are mounted on the lower arc seat 2, and a precision measuring mechanism 5 for comprehensively detecting the thickness of the curved curtain wall 1 is disposed on the upper arc plate 3; the precision measuring mechanism 5 comprises a moving member 51, a driving mechanism 52, a lifting mechanism 53, a moving frame 54 and a pressure detecting mechanism 55, wherein the moving member 51 is mounted on the upper arc plate 3, the driving mechanism 52 is used to drive the moving member 51 to move along the upper arc plate 3, the lifting mechanism 53 is mounted between the lower arc seat 2 and the upper arc plate 3, the moving frame 54 is connected to the bottom of the moving member 51, the pressure detecting mechanism 55 is mounted on the moving frame 54, and the pressure detecting mechanism 55 is used to detect the pressure change when the moving frame 54 moves along the curved curtain wall 1.

[0039] It should be noted that the plurality of telescopic members 4 are divided into two groups and are offset along the trajectory of the lower arc seat 2. When in use, a plurality of curved curtain walls 1 to be detected are sequentially placed between the two groups of telescopic members 4, and the two groups of telescopic members 4 are used to prevent the placed curved curtain walls 1 from tipping over. The driving mechanism 52 is started to drive the walking member 51 to move along the upper arc plate 3, and the walking member 51 drives the moving frame 54 to be sleeved on the curved curtain wall 1. At the same time, the lifting mechanism 53 is started to drive the upper arc plate 3 to lift and lower reciprocate, so that the pressure detection mechanism 55 is in full contact with both sides of the curved curtain wall 1.

[0040] When the thickness of the curved curtain wall 1 changes, the pressure value detected by the pressure detection mechanism 55 will also change adaptively. If the pressure change range is within the set standard range, the thickness uniformity is qualified. Conversely, if the detected pressure value exceeds or is lower than the set standard range, the thickness uniformity of the curved curtain wall 1 is unqualified.

[0041] like Figure 2-3 As shown, the lower arc seat 2 includes an arc bottom plate 21, a cavity 22, an arc socket 23, a guide rail 24 and a limit bar 25. The guide rail 24 is installed on the top of the arc bottom plate 21 near both ends. The cavity 22 is arranged in the arc bottom plate 21. Two arc sockets 23 are opened at the top of the arc bottom plate 21 and are connected with the cavity 22. The limit bar 25 is rotatably installed on the guide rail 24, and bolts are installed between the limit bar 25 and the guide rail 24.

[0042] It should be noted that the two arc-shaped sockets 23 and the arc-shaped bottom plate 21 are coaxially arranged, and the telescopic parts 4 in the two arc-shaped sockets 23 are respectively used to limit the two sides of the curved curtain wall 1. The guide rail 24 is used to facilitate pushing the curved curtain wall 1 to slide between the two sets of telescopic parts 4. One end of the limit strip 25 is rotatably connected to the top of the guide rail 24 through a hinge, and the other end is threadedly connected to the top of the guide rail 24 through a bolt. The limit strip 25 is used to facilitate limiting the curved curtain wall 1 at both ends.

[0043] like Figure 2 and Figure 4-5 As shown, the walking member 51 includes a frame 511, walking wheels 512 and an arc track plate 513. The frame 511 is movably connected to the upper arc plate 3. The two arc track plates 513 are respectively installed on the top and bottom of the upper arc plate 3. A plurality of walking wheels 512 are respectively rotatably installed on the facing inner walls on the upper and lower sides of the frame 511. The frame 511 moves along the arc track plate 513 through the walking wheels 512.

[0044] It should be noted that, in the present embodiment, four rectangularly distributed running wheels 512 are rotatably installed on the upper surface and the lower surface of the frame 511 respectively, and the axis of the running wheels 512 is perpendicular to the top and / or bottom of the frame 511. The running wheels 512 are used not only to conveniently limit the position of the frame 511 so that it can only move along the track of the arc-shaped track plate 513, but also to provide stable support for the frame 511.

[0045] like Figure 2-3 As shown, the telescopic member 4 includes an arc-shaped baffle 41 and a support spring 42 . The arc-shaped baffle 41 is slidably plugged into the arc-shaped socket 23 . The support spring 42 is installed in the cavity 22 , and the top end of the support spring 42 is connected to the bottom end of the arc-shaped baffle 41 .

[0046] It should be noted that multiple arc-shaped baffles 41 are evenly arranged along the arc-shaped socket 23. When the lifting mechanism 53 drives the moving frame 54 to move downward along the curved curtain wall 1, the arc-shaped baffle 41 corresponding to the moving frame 54 will be pressurized to adaptively slide down and compress the support spring 42. In this embodiment, since the walking member 51 will drive the moving frame 54 to move along the trajectory of the upper arc-shaped plate 3, when the moving frame 54 presses down the arc-shaped baffle 41 and slides along its top, in order to avoid affecting the movement of the walking member 51, when the moving frame 54 approaches the arc-shaped baffle 41 adjacent to the compressed arc-shaped baffle 41, the lifting mechanism 53 will realize the upward reset.

[0047] like Figure 2 and Figure 6 As shown, the driving mechanism 52 includes an arc-shaped rack 521, a gear 522, a rotating shaft 523, a sprocket 524, a chain 525, a servo motor 526 and a cover plate 527. The arc-shaped rack 521 is installed on one side of the upper arc plate 3, and the arc-shaped rack 521 passes through the frame 511. The rotating shaft 523 is rotatably installed in the frame 511. The gear 522 is sleeved on the rotating shaft 523 and meshed with the arc-shaped rack 521. The cover plate 527 is connected to the top of the frame 511. The servo motor 526 is installed on the top of the cover plate 527. The two sprockets 524 are respectively connected to the rotating shaft 523 and the output shaft of the servo motor 526, and the chain 525 is sleeved between the two sprockets 524.

[0048] It should be noted that the servo motor 526 is started to cooperate with the sprocket 524 and the chain 525 to drive the shaft 523 to rotate synchronously, and the shaft 523 drives the gear 522 meshing with the arc-shaped rack 521 to rotate. Since the position of the arc-shaped rack 521 is fixed and cannot be displaced, the frame 511 (such as Figure 4 As shown) moves along the trajectory of the upper curved plate 3.

[0049] like Figure 1-2As shown, the lifting mechanism 53 includes a bending plate 531, a support column 532, a cylinder 533 and a guide rod 534. The two bending plates 531 are respectively located at the two ends of the upper arc plate 3. The bottom of the bending plate 531 is connected to the top of the guide rail 24 through the support column 532. The cylinder 533 is installed on the top of the bending plate 531, and the cylinder 533 is used to drive the upper arc plate 3 to rise and fall. The guide rod 534 is slidably plugged into the bottom of the bending plate 531, and the top of the guide rod 534 is connected to the upper arc plate 3.

[0050] It should be noted that, in the present embodiment, the two cylinders 533 are raised and lowered synchronously. It is a prior art that the two cylinders 533 can realize synchronous lifting, and no further elaboration is given here. The cylinder 533 drives the upper arc plate 3 to realize overall lifting, and cooperates with the guide rod 534 to ensure the stability of the lifting of the upper arc plate 3.

[0051] like Figure 2 and Figure 7 As shown, the movable frame 54 includes a calibration plate 541 and a detection column 542 . The calibration plate 541 is fixedly installed at the middle position of the bottom of the frame 511 . The two detection columns 542 are symmetrically distributed about the center of the calibration plate 541 , and the detection columns 542 are fixedly connected to the calibration plate 541 .

[0052] It should be noted that the curvature of the calibration plate 541 is equal to the curvature of the standard curved curtain wall 1 , and the two detection columns 542 are symmetrically distributed about the center of the calibration plate 541 , which can ensure that the two detection columns 542 are spaced equally from both sides of the curved curtain wall 1 .

[0053] like Figure 7-8 As shown, the pressure detection mechanism 55 includes an extrusion member 551, a return spring 552, a pressure sensor 553 and a groove 554. The plurality of grooves 554 are respectively provided at the opposite side walls of the two detection columns 542. The extrusion member 551 is slidably connected to the groove 554. The pressure sensor 553 is installed at the bottom of the groove 554. The return spring 552 is connected between the extrusion member 551 and the pressure sensor 553. In order to conveniently display the pressure value, in this embodiment, a display screen 6 (such as a display screen 600 electrically connected to the pressure sensor 553) is installed on one side of the frame 511. Figure 1 shown).

[0054] It should be noted that when the moving frame 54 moves to the position where it is sleeved on the curved curtain wall 1, the extrusion piece 551 will be pressurized and compress the return spring 552. The specific pressure value can be detected by the pressure sensor 553. When the thickness of the contact between the curved curtain wall 1 and the extrusion piece 551 increases, the compression amount of the return spring 552 increases, and the detected pressure fluctuates. When the thickness of the contact between the curved curtain wall 1 and the extrusion piece 551 decreases, the compression amount of the return spring 552 decreases, and the detected pressure fluctuates. Therefore, the pressure fluctuation is used to facilitate a comprehensive detection of the thickness uniformity of the curved curtain wall 1.

[0055] like Figure 8-9 As shown, the extrusion member 551 includes a sliding portion 5511, an arcuate extrusion portion 5512 and a ball 5513. The sliding portion 5511 is slidably connected to the groove 554. The arcuate extrusion portion 5512 is symmetrically arranged at one end of the sliding portion 5511 away from the return spring 552. The ball 5513 is arranged between the two arcuate extrusion portions 5512.

[0056] It should be noted that the symmetrically arranged arcuate extrusion portion 5512 makes it easy for the movable frame 54 to drive the extrusion piece 551 to contact the edge of the curved curtain wall 1. The arcuate extrusion portion 5512 will be pressed to drive the extrusion piece 551 to slide adaptively along the groove 554. At the same time, the arcuate extrusion portion 5512 can transition the ball 5513 to form a point contact with the side wall of the curved curtain wall 1. The ball 5513 can not only avoid damage to the curved curtain wall 1 during movement, but also because it can realize point contact detection, it is conducive to realizing comprehensive detection of the curved curtain wall 1.

[0057] A working method for a curved curtain wall accuracy measuring device comprises the following steps:

[0058] S1: multiple curved curtain walls 1 to be inspected are sequentially arranged between a plurality of telescopic members 4 via guide rails 24, and then the deflection limit strips 25 are used to limit the curved curtain walls 1 at both ends;

[0059] S2: Start the driving mechanism 52 to drive the walking member 51 to move along the track of the upper arc plate 3, and the walking member 51 drives the moving frame 54 to move synchronously. When the moving frame 54 contacts the end of the curved curtain wall 1, the extrusion member 551 is pressed to slide adaptively along the groove 554 and compress the reset spring 552, and the specific pressure value is measured by the pressure sensor 553;

[0060] S3: Start the lifting mechanism 53 to drive the upper arc plate 3 to lift and lower back and forth. During the lifting process, the moving frame 54 will press the telescopic member 4 to make it adaptively extend and retract. In cooperation with the moving walking member 51, the multiple extrusion members 551 can be fully in contact with both sides of the curved curtain wall 1.

[0061] S4: The thickness uniformity of the curved curtain wall 1 can be determined by the fluctuation of the pressure value detected by the pressure sensor 553. If the detection pressure is greater than the maximum value of the set range, the thickness of the curved curtain wall 1 at this point exceeds the standard. If the detection pressure is lower than the minimum value of the set range, the thickness of the curved curtain wall 1 at this point is insufficient.

[0062] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
