Description

Technical Field

[0001] The present invention relates to the technical field of perpendicularity detection equipment, and particularly relates to a perpendicularity detection equipment for outer window installation and a detection method thereof. Background Art

[0002] As a key part of the building envelope, the installation quality of outer windows directly affects the safety, functionality and durability of the building. Perpendicularity detection is a core link in outer window installation. The inclination of the window frame will cause uneven gaps between the window sash and the frame body, weaken the waterproof effect of the sealing strip or sealant, and cause rainwater leakage. The risk is exacerbated especially in extreme weather such as typhoons and heavy rains. Excessive deviation of the perpendicularity of the window frame will cause uneven stress on the window body, which may lead to metal fatigue and glass stress concentration in the long term, and even affect the overall wind resistance performance of the building.

[0003] When detecting the perpendicularity of the window frame, generally the plumb line method or the mechanical straightedge is used;

[0004] Plumb line: Using the principle of gravity to hang a plumb line, and visually comparing the distance difference between the window frame and the plumb line. This method has limitations, relying on manual reading, with low accuracy and being easily interfered by wind, and is only applicable to low-precision scenarios.

[0005] Mechanical straightedge: Judging the perpendicularity through a bubble level. This method has low operation efficiency and cannot adapt to the detection of high-altitude or large-size window bodies. Summary of the Invention

Specific embodiments

[0044] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] Embodiment, as Figures 1 to 4 and Figures 12 to 14 shown, on the one hand, a verticality detection device for outer window installation proposed by the present invention includes two sets of adsorption assemblies 1 for fixedly connecting with the window frame 9. The adsorption assemblies are connected with a base 3 through a connecting plate 2. The adsorption assembly 1 includes an adsorption cylinder 101. A plug 102 is slidably installed in the adsorption cylinder 101. A screw 103 is threadedly connected to the adsorption cylinder 101. The screw 103 is rotatably connected to the plug 102. When fixing, first, the adsorption cylinder 101 is attached to the window frame 9, and the screw 103 is rotated to drive the plug 102 to move away from the window frame, thereby reducing the air pressure between the window frame 9 and the plug 102. Through the action of the internal and external pressure difference, the adsorption assembly 1 can be fixed on the window frame. A magnetic attraction ring 104 is fixedly installed on the adsorption cylinder 101. If the material of the window frame 9 can be adsorbed by a magnet, it can be directly adsorbed and fixed through the magnetic attraction ring 104. A connecting pipe 105 is rotatably installed on the adsorption cylinder 101. A slideway 106 is slidably installed on the connecting pipe 105. The connecting plate 2 is fixedly connected to the slideway 106, enabling the connecting plate 2 to rotate and translate, facilitating the adjustment of the upper and lower two connecting plates 2 to a parallel position.

[0046] Further, after the two adsorption components 1 are installed, the positions of the two bases 3 need to be adjusted. The two bases 3 need to be in a position where they are parallel to each other and their sides coincide. An installation box 8 is fixedly installed on one of the bases 3. A connecting shaft 801 is rotatably installed in the installation box 8. A winch 802 is fixedly installed on the connecting shaft 801. A pulling rope 803 is fixedly installed on the winch 802. One end of the pulling rope 803 extends to the outside of the installation box 8 and is fixedly installed with a connecting hook 804. A connecting ring 805 that cooperates with the connecting hook 804 is fixedly installed on the other base 3. By connecting the connecting hook 804 and the connecting ring 805 to each other and tightening the pulling rope 803, under the pulling force of the connecting rope, the sides of the two bases 3 can be moved to a parallel and coincident position. This is because when the pulling rope 803 is tightened, the pulling force will gradually increase. Due to the constraint of the length of the pulling rope 803, the two bases 3 will slide along the slideway 106, gradually reducing the distance in the horizontal direction. When the two bases 3 approach the same straight line, the pulling force direction of the pulling rope 803 is the same as the supporting force direction of the slideway 106 on the base 3, and the system reaches equilibrium.

[0047] After the pulling rope 803 is adjusted to a tightened state, in order to prevent the position of the base 3 from changing, the pulling rope 803 needs to be fixed to prevent the pulling rope 803 from loosening. Among them, a ratchet wheel 806 is fixedly installed on the installation box 8. A connecting disk 807 is slidably installed on the connecting shaft 801. There is a circumferential positioning between the connecting disk 807 and the connecting shaft 801. A pawl 808 is rotatably installed on the connecting disk 807 and a limiting block 809 is fixedly installed. A turning handle 810 is fixedly installed on the connecting disk 807. By pulling the turning handle 810, the connecting disk 807 and the pawl 808 can be driven to move, and it can be controlled whether the pawl 808 can cooperate with the ratchet wheel 806. When they cannot cooperate, the connecting shaft 801 can be freely rotated to scale the pulling rope 803. When the pulling rope 803 needs to be tightened, press the turning handle 810 to make the pawl 808 cooperate with the ratchet wheel 806, and the connecting shaft 801 can be limited, so that the connecting shaft 801 can only rotate in one direction, that is, the connecting shaft 801 can only tighten the pulling rope 803 to prevent the pulling rope 803 from loosening.

[0048] It should be noted that a first laser rangefinder 4 is fixedly installed on one of the bases 3, and a first reflector 401 is fixedly installed on the other base 3. Since the adsorption assembly is attached to the window frame 9, the adsorption assembly 1 and the window frame 9 are in a parallel state, and thus the base 3 and the window frame 9 are also in a parallel state. Assuming two points are selected on the same vertical plane of the window frame 9, the distance between these two points at this time is L1. The length detected by the first laser rangefinder 4 at this time is L1. At this time, as long as the distance L2 between the projections of these two points on the vertical plane perpendicular to this plane is known, the inclination angle of the window frame 9 can be obtained according to trigonometric functions;

[0049] According to the sizes of different window frames 9, the length of L1 between the two points needs to be reasonably selected. And for this device, by setting two groups of bases 3, the two groups of bases 3 are connected by a pull rope 803, which can effectively reduce the volume of the device, greatly improve the measurement range of the device, achieve a highly lightweight design, and facilitate carrying and installation.

[0050] Such as Figures 5 to 7 and Figure 10 As shown, this embodiment further includes a plumb bob module 5 installed on the base 3. A second laser rangefinder 601 is installed on one of the plumb bob modules 5, and a second reflector 602 is fixedly installed on the other plumb bob module 5. The plumb bob module includes driving the second laser rangefinder 601 and the second reflector 602 to move to the vertical position. Through the mutual cooperation of the second laser rangefinder 601 and the second reflector 602, the distance L3 can be detected. If L3 is equal to L2, the system can directly perform data processing and calculation to directly obtain the inclination angle of the window frame 9. To ensure that L2 and L3 can be kept equal, the following processing is provided:

[0051] The laser emission points of the second laser rangefinder 601 and the first laser rangefinder 4 are on the same axis, and the second laser rangefinder 601 rotates around this axis so that the laser emission point of the second laser rangefinder 601 always maintains the same position as the first laser rangefinder 4, that is, the ranging starting points are always equal. For the ranging end point, under the action of the plumb bob module 5, the bottom of the second reflector 602 can be in a horizontal position. Since the intersection point of the first reflector 401 and the first laser rangefinder 4 and the midpoint of the bottom surface of the second reflector 602 are on the same axis, and the second reflector 602 rotates around this axis, the projection of the detection end point of the first laser rangefinder 4 on the vertical plane will coincide with the ground of the second reflector 602, so that L2 and L3 can be kept equal. And since L1 and L2, and the connection lines of L1 and L2 form a right triangle, the angle between the window frame 9 and the vertical plane can be calculated using trigonometric functions, and thus the perpendicularity of the window frame 9 can be obtained.

[0052] Furthermore, the plumb bob module 5 includes a supporting block 501 fixedly mounted on the base 3, a connecting ball 502 is rotatably mounted in the supporting block 501, an extension rod 503 is fixedly mounted on the connecting ball 502, a counterweight 504 is fixedly mounted on one end of the extension rod 503, and a connecting seat 510 is fixedly mounted on the other end, a second laser rangefinder 601 and a second reflector 602 are detachably connected to the connecting seat 510, and the plumb bob module 5 also includes a plurality of limiting components for limiting the connecting ball 502, under the action of the gravity of the counterweight 504, the extension rod 503 can be driven to rotate to a vertical position, and when the extension rod 503 moves to the vertical position, the extension rod 503 is limited by the limiting component, so as to prevent the extension rod 503 from shaking due to external force during the measurement process.

[0053] The connection seat 510 is detachably provided with a connection member 6, one of which is fixedly connected to the second laser rangefinder 601, and the other is fixedly connected to the second reflector 602. After the extension rod 503 is limited, the connection member 6 can be installed on the connection seat 510.

[0054] The limiting assembly includes a sleeve 505 rotatably mounted on the extension rod 503, a sealing block 506 is slidably mounted in the sleeve 505, a sliding rod 507 is fixedly mounted on the sealing block 506, the sliding rod 507 passes through one end of the sleeve 505 and is rotatably connected to the support block 501, the two ends of the sleeve 505 are connected through a pipe 508, an electric control valve 509 is fixedly mounted on the pipe 508, the sleeve 505 and the pipe 508 are filled with fluid, when the extension rod 503 rotates, the sleeve 505 will be driven to move, which will The sleeve 505 and the sliding rod 507 rotate synchronously and the total length changes, that is, when the extension rod 503 moves, the sealing block 506 slides inside the sleeve 505. When the electric control valve 509 is opened, the sealing block 506 can move freely. However, when the electric control valve 509 is closed, the fluid on both sides of the sleeve 505 cannot circulate. At this time, the sealing block 506 cannot move, and the extension rod 503 cannot continue to move. The fluid here is a liquid that cannot be compressed under the working environment.

[0055] like Figures 7 to 11 As shown, this embodiment also includes an active damping system 7, which detects the magnitude of the swing amplitude of the plumb bob module 5 and controls the damping applied to the plumb bob module 5 when it rotates. The active damping system 7 includes an amplitude detection module for detecting the swing amplitude of the connecting ball 502 and an execution module for adjusting the magnitude of the damping applied to the connecting ball 502. By detecting the swing amplitude of the extension rod 503 and dynamically adjusting the resistance, that is, applying a larger resistance when the amplitude is large and reducing the resistance when the amplitude is small, the shaking time of the object can be significantly shortened.

[0056] When swinging significantly: Apply a large resistance to quickly consume kinetic energy and shorten the amplitude decay time.

[0057] When swinging slightly: Reduce the resistance to avoid over-inhibition leading to system rigidity, and at the same time allow natural damping to gradually dissipate energy.

[0058] Furthermore, the amplitude detection module includes a cylinder 701 fixedly installed on the extension rod 503. A plurality of fins 702 are fixedly installed on the cylinder 701 in a circumferential array. A plurality of air holes 703 are provided between adjacent fins 702 on the cylinder 701. The fins 702 can increase the contact area between the cylinder 701 and the air, and can increase the air resistance borne by the cylinder 701 when it sways with the extension rod 503. Moreover, the fins 702 can guide the gas into the air holes 703. A gas tank 704 and a plurality of connection boxes 705 are fixedly installed inside the cylinder 701. The connection boxes 705 communicate with the same group of air holes 703. The gas tank 704 communicates with the plurality of connection boxes 705 through a plurality of one-way valves 706. The gas passing through the air holes 703 will enter the gas tank 704 through the one-way valves 706. And due to the setting of the one-way valves 706, the gas can only enter the gas tank 704 unidirectionally, preventing the gas inside the gas tank 704 from being discharged through the air holes 703 on the other side. An air duct 707 communicating with the gas tank 704 is provided inside the extension rod 503. A plurality of exhaust holes 708 are provided at the bottom of the air duct 707. An airbag 709 is fixedly connected to the support block 501 outside the plurality of exhaust holes 708. A pressure sensor 710 is fixedly installed inside the airbag 709. The gas entering the gas tank 704 will move along the air duct 707 and be ejected through the exhaust holes 708. The gas ejected from the exhaust holes 708 will exert a certain pressure on the airbag 709, which will in turn have a certain impact on the air pressure inside the airbag 709. The pressure inside the airbag 709 is detected by the high-precision pressure sensor 710, and the swing amplitude of the extension rod 503 can be indirectly judged. Specifically:

[0059] Detect the maximum value of the pressure inside the airbag 709 through the pressure sensor 710. Since the larger the swing amplitude of the extension rod 503, the greater the kinetic energy and speed when it rotates to the lowest point, and thus the greater the flow rate of the gas inside the air holes 703, which will lead to a greater pressure exerted on the airbag 709. Based on this, the swing amplitude of the extension rod 503 can be judged.

[0060] By monitoring the time interval between two times when the pressure of the pressure sensor 710 is 0, when the extension rod 503 swings: gravitational potential energy - kinetic energy - gravitational potential energy. During this process, when the extension rod 503 moves to the highest point, its speed is 0, and at this time, the reading monitored by the pressure sensor 710 is also 0. Subsequently, the extension rod 503 will descend and its speed will gradually increase. After passing through the lowest point, the speed will gradually decrease until it returns to 0 again. The larger the swing amplitude, the longer the time interval. Therefore, the swing amplitude can be judged by the interval between the two sides of the pressure sensor 710 when the pressure is 0.

[0061] Furthermore, a placement groove 711 is provided in the support block 501. The execution module includes a friction plate 712 slidably installed in the placement groove 711. A pressure rod 713 is fixedly installed on the friction plate 712. A sliding cylinder 714 is fixedly installed on the support block 501. The pressure rod 713 is slidably connected to the sliding cylinder 714. A pressure block 715 is slidably installed in the sliding cylinder 714. A spring 716 is fixedly installed between the pressure block 715 and the pressure rod 713. A linear motor 717 is fixedly installed on the sliding cylinder 714. The output shaft of the linear motor 717 is fixedly connected to the pressure block 715. By means of the linear motor 717, the pressure block 715 can be driven to compress or stretch the spring 716, and thus the pressure exerted by the spring 716 on the friction plate 712 can be controlled. The magnitude of this pressure will determine the magnitude of the resistance between the connecting ball 502 and the friction plate 712. When used in combination with the amplitude detection module, the effect of quickly consuming the energy of the extension rod 503 can be achieved, enabling the extension rod 503 to quickly return to the vertical state and improving the detection efficiency.

[0062] On the other hand, the present invention proposes a verticality detection method for external window installation, which is applied to the above-mentioned verticality detection device for external window installation. The method includes the following steps:

[0063] Step 1: Fix the adsorption assembly 1 on the upper and lower sides of the window frame 9.

[0064] Step 2: Connect the two bases 3 through the pull rope 803, tighten the pull rope 803, and under the action of the tension of the pull rope 803, make the two bases 3 slide along the slideway 106 to the same plane, and fix the pull rope 803.

[0065] Step 3: Drive the bottom surface of the second reflector 602 to rotate to the horizontal position through the plumb bob module 5, and make the second laser rangefinder 601 rotate to the vertical position.

[0066] Step 4: Apply damping to the swaying plumb bob module 5 through the active damping system 7, and gradually reduce the damping as the swaying amplitude of the plumb bob module 5 decreases, so that the plumb bob module 5 quickly returns to the stationary state.

[0067] Step 5: Detect the distance between the first laser rangefinder 4 and the first reflector 401, and detect the distance between the second laser rangefinder 601 and the second reflector 602;

[0068] Step 6: Calculate the data through the data processing system, and the perpendicularity of the window frame 9 can be judged through trigonometric functions.

[0069] Working principle: First, attach the adsorption cylinder 101 to the window frame 9, and rotate the screw 103 to drive the plug 102 to move away from the window frame, thereby reducing the air pressure between the window frame 9 and the plug 102. Through the action of the internal and external pressure difference, the adsorption assembly 1 can be fixed on the window frame;

[0070] By connecting the connecting hook 804 with the connecting ring 805 and tightening the pull rope 803, under the pulling force of the connecting rope, the sides of the two bases 3 can be moved to parallel and coincident positions;

[0071] Under the action of the gravity of the counterweight 504, the extension rod 503 can be driven to rotate to the vertical position. After the extension rod 503 moves to the vertical position, the extension rod 503 can be limited by the limiting component to prevent the extension rod 503 from shaking due to external forces during the measurement process;

[0072] The length detected by the first laser rangefinder 4 is L1. Through the mutual cooperation of the second laser rangefinder 601 and the second reflector 602, the distance L3 can be detected. If L2 and L3 can be kept equal, the system can directly perform data processing and calculation to directly obtain the inclination angle of the window frame 9.

[0073] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
