DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Example: Refer to Figure 1-Figure 8 A window opener chain flexibility detection device comprises a detection base 1, and also comprises: a mounting shaft 2 rotatably connected to the detection base 1, a mounting frame 3 fixedly mounted on the mounting shaft 2; a guide column 4 fixedly mounted on the mounting frame 3; a mounting portion fixedly mounted on the guide column 4, used for mounting the window opener; a pressure drop detection component slidably arranged on the guide column 4; a driving portion arranged on the mounting frame 3, used for driving the pressure drop detection component to switch the detection mode of the window opener; when the pressure drop detection component is located below the mounting portion, the window opener starts to drag the pressure drop detection component up to detect the pulling force of the window opener; when the pressure drop detection component is located above the mounting portion, the window opener starts to push the pressure drop detection component up to detect the thrust of the window opener.

[0035] During the inspection, first install the window opener on the mounting part, then start the window opener to extend the chain of the window opener, make the connecting metal plate at the end of the chain stick to the pressure drop detection component, and fix the connecting metal plate. The driving part drives the mounting frame 3 to rotate 90° through the mounting shaft 2, so that the pressure drop detection component is located above the mounting part, and then start the window opener to extend the chain. The window opener lifts the pressure drop detection component through the chain, and then detects the thrust of the chain through the pressure drop detection component. Then the mounting shaft 2 is driven to rotate 180°, so that the pressure drop detection component moves to the bottom of the window opener, and then the window opener retracts the chain. During the retraction process, the pressure drop detection component detects the tension received by the chain to determine whether the tension of the window opener is qualified.

[0036] Reference Figure 1 and Figure 3-Figure 6 The driving part includes a driving motor 24 fixedly connected to the detection base 1 , a second transmission bevel gear 25 is fixedly mounted on the output end of the driving motor 24 , a first transmission bevel gear 23 is fixedly mounted on the mounting shaft 2 , and the first transmission bevel gear 23 is meshed with the second transmission bevel gear 25 .

[0037] Start the drive motor 24, the drive motor 24 drives the second transmission bevel gear 25 to rotate, the second transmission bevel gear 25 drives the first transmission bevel gear 23 to rotate, the first transmission bevel gear 23 drives the installation shaft 2 to rotate, and the installation shaft 2 drives the installation frame 3 to rotate, thereby changing the position of the pressure drop detection component and the installation part.

[0038] Reference Figure 4 The mounting portion includes a mounting seat 10 fixedly mounted on the guide column 4, a slide groove 11 is provided in the mounting seat 10, and the cross section of the slide groove 11 is convex-shaped, and a slot hole 12 connected to the slide groove 11 is provided on the mounting seat 10.

[0039] During the inspection, the window opener is inserted into the slide groove 11. During this process, the chain discharge end of the window opener is facing the slot hole 12. After the window opener is inserted into the slide groove 11, the window opener is started so that the chain of the window opener is discharged from the slide groove 11 through the slot hole 12 and adheres to the pressure drop detection component.

[0040] Reference Figure 3 A telescopic cylinder 14 is fixedly installed in the slide slot 11 , and a first electromagnet 15 is fixedly connected to the output end of the telescopic cylinder 14 .

[0041] When the window opener contacts the first electromagnet 15, the first electromagnet 15 is energized to generate magnetic force to attract the metal shell of the window opener. When performing tension detection, the telescopic cylinder 14 is started to drive the first electromagnet 15 to move back and forth, thereby driving the metal shell of the window opener to move back and forth, thereby changing the position of the connecting metal plate at the end of the chain and the metal shell, and adjusting the inclination angle of the chain to detect the flexibility of the chain.

[0042] Reference Figure 1-Figure 8 , the fall detection assembly comprises a fall pressing part and a detection part, wherein the fall pressing part comprises a slide plate 6 slidably connected to the guide column 4, a counterweight box 7 is fixedly connected to the slide plate 6, a vibration motor 17 is fixedly installed on the counterweight box 7, and the detection part comprises a mounting column 18 fixedly installed on the slide plate 6, a limit plate 19 is fixedly installed at the bottom of the mounting column 18, a connecting plate 22 is slidably connected to the mounting column 18, a second electromagnet 16 is fixedly installed on the connecting plate 22, a first pressure detection sensor 20 and a second pressure detection sensor 21 are fixedly connected to the connecting plate 22, the first pressure detection sensor 20 and the second pressure detection sensor 21 are respectively arranged on two symmetrical surfaces of the connecting plate 22, the first pressure detection sensor 20 is against the counterweight box 7, and the second pressure detection sensor 21 is against the limit plate 19.

[0043] When the chain of the window opener extends out with the connecting metal plate, the connecting metal plate contacts the second electromagnet 16, and the second electromagnet 16 is energized to generate magnetic force to fix the connecting metal plate, thereby fixing the end of the chain.

[0044] When the counterweight box 7 is located above the window opener, the chain extends to push the counterweight box 7 upward. During this process, the first pressure detection sensor 20 abuts against the counterweight box 7 to detect the weight of the counterweight box 7 and further detect the thrust of the window opener chain.

[0045] When the counterweight box 7 is located below the window opener, the window opener retracts the chain, and the chain drags the counterweight box 7 up. At this time, the second pressure detection sensor 21 is against the limit plate 19 to detect the weight of the counterweight box 7, and then detects the tension of the window opener zipper.

[0046] During the detection, the vibration motor 17 can also be started, and the vibration motor 17 drives the counterweight box 7 to vibrate, thereby simulating the working state of the window opener under the vibration of the window, and then detecting whether the window opener can open or close the window when the window vibrates.

[0047] Reference Figure 3 and Figure 5 A storage box 5 is fixedly mounted on the mounting frame 3 , and a flow medium (including water, fine dry sand, etc.) is stored in the storage box 5 . The storage box 5 is connected to the counterweight box 7 through a hose 8 , and a control valve 9 is provided on the hose 8 .

[0048] When in use, when the storage box 5 is located above the counterweight box 7, the control valve 9 is opened, and the flow medium in the storage box 5 flows into the counterweight box 7 through the hose 8, gradually increasing the weight of the counterweight box 7, and then detecting the weight limit that the chain of the window opener can bear. When the counterweight box 7 is higher than the storage box 5, the control valve 9 is opened to allow the flow medium to flow from the counterweight box 7 back into the storage box 5 for storage.

[0049] Reference Figure 1 , Figure 5 and Figure 6 A mounting plate 27 is fixedly mounted on the detection base 1, and an all-in-one controller 28 is fixedly mounted on the mounting plate 27, wherein the all-in-one controller 28 includes a display screen and a controller operated using the display screen, which is used to control the speed and number of revolutions of the driving motor 24, and also to control the vibration motor 17 and the switch of the control valve 9.

[0050] Reference Figure 4 A limit plate 13 is also fixedly installed on the guide column 4. The limit plate 13 is provided with two sets, upper and lower, for limiting the sliding distance of the counterweight box 7, preventing the vibration motor 17 from colliding with the mounting frame 3, and preventing the slide plate 6 from colliding with the mounting seat 10.

[0051] Reference Figure 1-Figure 5 A mounting tube 26 is fixedly mounted on the detection base 1, and holes are provided at both ends of the mounting tube 26. The mounting frame 3 rotates inside the mounting tube 26, wherein the rotation range of the pressure drop detection component, the mounting portion and the storage box 5 are all within the mounting tube 26, so that the mounting tube 26 is used to shield the pressure drop detection component, the mounting portion and the storage box 5 to prevent accidental injury to the staff when the pressure drop detection component, the mounting portion and the storage box 5 rotate.

[0052] In summary, by changing the positional relationship between the pressure drop detection component and the mounting portion, the push and pull force can be detected separately, and there is no need to install the window opener on different equipment for tension and push force detection, which improves the detection efficiency and reduces the detection cost of chain tension and push force.

[0053] By driving the counterweight box 7 to vibrate through the vibration motor 17, the scene of window vibration when the window is pushed and closed can be simulated, so as to detect the stability and reliability of the window opener under the condition of window vibration;

[0054] A flowing medium (such as water, fine dry sand, etc.) is injected into the counterweight box 7 through the storage box 5 and the hose 8, and the weight of the counterweight box 7 is gradually increased, so as to detect the load-bearing capacity limit of the window opener chain.

[0055] A window opening machine detection method comprises the following steps:

[0056] Step 1: Install the window opener on the mounting portion, specifically: insert the window opener into the mounting portion (such as the slide slot 11 of the mounting seat 10), ensure that the chain discharge end of the window opener faces the slot hole 12, and adjust the position of the window opener so that it is firmly mounted on the mounting portion;

[0057] Step 2: The position of the mounting part and the pressure drop detection component is adjusted by the driving part. When the pressure drop detection component is located below the mounting part, the window opener starts to drag the pressure drop detection component upward to detect the pulling force of the window opener. When the pressure drop detection component is located above the mounting part, the window opener starts to push the pressure drop detection component upward to detect the thrust of the window opener. Specifically:

[0058] The position of the mounting part and the pressure drop detection component are adjusted by the drive unit, and push and pull force detection is performed

[0059] Adjust the position: start the drive motor 24, and drive the installation shaft 2 to rotate through the meshing of the first transmission bevel gear 23 and the second transmission bevel gear 25, thereby driving the installation frame 3 and the pressure drop detection assembly to rotate to the desired position;

[0060] When the crush detection assembly is located below the mounting portion, prepare for the tensile test;

[0061] When the pressure drop detection assembly is located above the mounting portion, the thrust detection is ready;

[0062] Tensile test:

[0063] Ensure that the slide plate 6 and the counterweight box 7 of the crush detection assembly are located directly below the window opener;

[0064] The window opener is started to extend the chain, and the connecting metal plate at the end of the chain contacts and is fixed to the second electromagnet 16;

[0065] The window opener drags the pressure drop detection assembly upwards through the chain, and the first pressure detection sensor 20 detects and records the tension data;

[0066] Thrust detection:

[0067] The mounting frame 3 is adjusted by the driving unit so that the pressure drop detection assembly is located above the window opening machine;

[0068] The window opener starts, the chain extends and pushes the pressure drop detection assembly to rise, and the second pressure detection sensor 21 detects and records the thrust data.

[0069] Step 3: Start the telescopic cylinder 14, which drives the window opener to move back and forth, adjusts the inclination angle between the window opener and the chain, and drives the window opener box to move back and forth to detect the flexibility of the window opener chain. Specifically:

[0070] Start the telescopic cylinder 14: After the tension or thrust is detected, start the telescopic cylinder 14 to drive the first electromagnet 15 to move back and forth;

[0071] Adjusting the tilt angle: Since the first electromagnet 15 and the metal shell of the window opener are attracted to each other, the reciprocating motion of the telescopic cylinder 14 will drive the window opener box (i.e. the window opener as a whole) to move back and forth in the slide slot 11, thereby changing the position between the connecting metal plate at the end of the chain and the metal shell, and then adjusting the tilt angle of the chain;

[0072] Flexibility test: When adjusting the tilt angle, observe and record the movement of the chain to evaluate whether its flexibility meets the requirements; pay attention to checking whether the chain moves smoothly at different tilt angles and whether there is any jamming.

[0073] In addition, there are optional testing steps, including:

[0074] 1. Vibration simulation test: During the tension or thrust test, the vibration motor 17 can be started to simulate the working condition of the window under vibration, and the response of the window opener and the chain can be observed and recorded to evaluate its stability and reliability in complex environments.

[0075] 2. Limit weight test: inject flowing medium (such as water, fine dry sand, etc.) into the counterweight box 7 through the storage box 5 and the hose 8, gradually increase the weight of the counterweight box 7, and test the load-bearing capacity limit of the window opener chain. Pay attention to gradually increase the weight during the test, and observe and record the response of the chain and the window opener.

[0076] Through the detailed supplement and refinement of the above steps, the window opener detection method can evaluate the performance of the window opener more comprehensively and accurately.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
