Description

Technical Field

[0001] This utility model relates to the field of testing technology for anti-fall devices for exterior windows, specifically a performance testing device for anti-fall devices for building exterior windows. Background Technology

[0002] Building windows are a critical part of the building envelope, and their safety is directly related to the personal safety of people. Fall protection devices (such as fall ropes and limiters) are the core safety components in the window system to prevent window sashes from falling accidentally. Their function is to provide the last physical protection when the window sash connection parts fail, keeping the window sash within the window frame range, thereby avoiding the risk of falling objects from heights. To ensure that the performance of fall protection devices is absolutely reliable, they must be rigorously tested by specialized performance testing equipment.

[0003] Existing devices directly conduct a mechanical test on the materials of the fall arrestor, but cannot simulate whether the connection and materials of the fall arrestor can withstand the impact of a sudden fall when it is installed on a window sash and other connections fail.

[0004] Based on this, a performance testing device for anti-fall devices for building exterior windows is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide a performance testing device for anti-fall devices on building exterior windows, so as to solve the problem in the background technology that it is impossible to simulate the installation of anti-fall devices on window sashes, and whether the connection and materials can withstand the impact of sudden falling when other connections fail.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

An anti-fall rope is provided between two of the anti-fall mounting components.

[0008] The installation box is equipped with an adjustment mechanism inside, and an adsorption mechanism is provided on one side of the adjustment mechanism.

[0011] In one alternative: a slidingly mounted limiting rod extends through one side of the movable frame, and the limiting rod is fixedly connected to the mounting box.

[0012] In one alternative: the adsorption mechanism includes two suction cups, both of which are fixedly mounted on one side of the movable frame by bolts. An air compressor and a vacuum pump are respectively placed inside the mounting box. The air compressor is connected to the vacuum pump through a conduit, and the vacuum pump is connected to the two suction cups through conduits.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, the performance testing device for the anti-fall device of building exterior windows includes an internal pressurization device 1 and a testing mechanism. An installation box 2 is provided on one side of the internal pressurization device 1. Multiple quick-installation mechanisms 3 are provided on one side of the installation box 2. A window frame 4 is installed on one side of the installation box 2 through the multiple quick-installation mechanisms 3. A test window 5 is installed on one side of the window frame 4 through hardware. Anti-fall installation components 6 are provided on both the inner side of the window frame 4 and the outer side of the test window 5. An anti-fall rope 7 is provided between two of the anti-fall installation components 6.

[0027] An adjustment mechanism 8 is provided inside the installation box 2, and an adsorption mechanism 9 is provided on one side of the adjustment mechanism 8.

[0028] In this embodiment, the window frame 4 is installed to the mounting box 2 via the quick-installation mechanism 3, and the test window 5 is installed to the window frame 4 using hardware. The test window 5 is effectively fixed by the coordination of the adjustment mechanism 8 and the adsorption mechanism 9. Then, the hardware used to fix the test window 5 is removed, leaving only the anti-fall mounting component 6 and the anti-fall rope 7. The internal pressurization device 1 is equipped with a fan and an air flow meter. Air is generated by the fan and blown onto the surface of the test window 5. The air flow rate is controlled by the coordination of the air flow meter and the fan, simulating the window sash under actual conditions. In actual use, under the design wind load, when the test window 5 is in a stable state under the set wind pressure, the suction cup 93 is switched to the blowing state, and the window sash is suddenly released. At this time, the test window 5 is only suspended by the anti-fall mounting piece 6 and the anti-fall rope 7. The instantaneous performance of the anti-fall mounting piece 6 and the anti-fall rope 7 under the sudden falling impact is recorded. After the test window 5 falls, the second motor 12 is started to simulate the continuous wind load environment under the condition of not being dealt with in time. The stability of the anti-fall mounting piece 6 and the anti-fall rope 7 under the continuous wind load is observed, and the suspension time and whether failure occurs are recorded.

[0029] In one embodiment, such as Figure 3 and Figure 4 As shown, the adjusting mechanism 8 includes a fixed plate 81, which is fixedly installed inside the mounting housing 2 on one side. A lead screw 82 is rotatably mounted on one side of the fixed plate 81 via a bearing, and one end of the lead screw 82 is rotatably mounted to the mounting housing 2 via a bearing. A first motor 83 is fixedly mounted on the other side of the fixed plate 81, and the lead screw 82 is driven by the first motor 83. A movable frame 84 is threaded onto the outside of the lead screw 82. A sliding limit rod 85 passes through one side of the movable frame 84, and the limit rod 85 is fixedly connected to the mounting housing 2. The adsorption mechanism 9 includes two suction cups 93, both of which are fixedly mounted on one side of the movable frame 84 by bolts. An air compressor 91 and a vacuum pump 92 are respectively placed inside the mounting box 2. The air compressor 91 is connected to the vacuum pump 92 through a conduit. The vacuum pump 92 is connected to two suction cups 93 through conduits. The first motor 83 drives the lead screw 82 to rotate, thereby changing the position of the moving frame 84, so that the suction cups 93 are close to the test window 5 until they are in contact, which is convenient for adjustment according to different windows and improves adaptability. At this time, the air compressor 91 and the vacuum pump 92 are working, so that the suction cups 93 are in the suction state, thereby firmly fixing the test window 5 and the suction cups 93. When the test window 5 is in a stable state under the set wind pressure, the vacuum pump 92 switches the mode, so that the suction cups 93 are in the blowing state, and suddenly release the window sash.

[0030] In one embodiment, such as Figure 2 and Figure 3As shown, the quick-installation mechanism 3 includes a fixing block 31, which is fixedly connected to one side of the mounting box 2. A rotating component 32 is rotatably installed on one side of the fixing block 31, and a knob 33 passes through one side of the rotating component 32. The knob 33 and the fixing block 31 are connected by a thread. When the window frame 4 needs to be installed with the mounting box 2, first loosen the knob 33 so that the rotating component 32 rotates to a state that does not obstruct the installation of the window frame 4. Then, fit the window frame 4 with the mounting box 2, rotate the rotating component 32 to a state that obstructs the window frame 4, and finally lock the knob 33. This structure is simple and can quickly install the window frame 4 with the mounting box 2.

[0031] In one embodiment, such as Figure 1 As shown, the testing mechanism includes a fixed frame 10, with four brake casters 11 at the bottom. A second motor 12 is fixedly mounted on the top of the fixed frame 10, and a protective cover 13 is fixedly mounted on the outside of the second motor 12. A propeller blade 14 is keyed to the output end of the second motor 12 and located inside the protective cover 13. The propeller blade 14 is opposite to the test window 5. The fixed frame 10 is moved to the opposite side of the test window 5 by means of the brake casters 11. The second motor 12 drives the propeller blade 14 to rotate. The rotation of the propeller blade 14 generates airflow that acts on the test window 5. The stability of the fall arrestor 6 and the fall arrestor rope 7 under continuous wind load is observed, and the suspension time and whether failure occurs are recorded.

[0032] The above embodiments disclose a performance testing device for a building exterior window anti-fall device. When installing the window frame 4 to the mounting box 2, first loosen the knob 33 so that the rotating part 32 rotates to a state that does not obstruct the installation of the window frame 4. Then, attach the window frame 4 to the mounting box 2, rotate the rotating part 32 to a state that obstructs the window frame 4, and finally tighten the knob 33. This structure is simple and allows for quick installation of the window frame 4 to the mounting box 2. The first motor 83 drives the lead screw 82 to rotate, thereby changing the position of the moving frame 84, causing the suction cup 93 to approach the test window 5 until it is in contact with it. At this time, the air compressor 91 and the vacuum pump 92 work, causing the suction cup 93 to be in a suction state, thereby allowing the test window to be installed. Window 5 is securely fixed to suction cup 93. The hardware used to fix test window 5 is removed, leaving only the anti-fall mounting piece 6 and the anti-fall rope 7. The internal pressurization device 1 is equipped with a fan and an air flow meter. The fan generates air that blows onto the surface of test window 5. The air flow meter and the fan work together to control the air flow, simulating the state of the window sash under the design wind load in actual use. When test window 5 is in a stable state under the set wind pressure, suction cup 93 is switched to the air blowing state, and the window sash is suddenly released. At this time, test window 5 is only suspended by the anti-fall mounting piece 6 and the anti-fall rope 7. The instantaneous performance of the anti-fall mounting piece 6 and the anti-fall rope 7 under the sudden impact force is recorded.

[0033] After the test window 5 falls, the fixing frame 10 is moved to the opposite side of the test window 5 by the brake caster 11. The second motor 12 drives the propeller blade 14 to rotate. The rotation of the propeller blade 14 generates airflow that acts on the test window 5. The stability of the fall arrestor 6 and the fall arrestor rope 7 under continuous wind load is observed, and the suspension time and whether failure occurs are recorded.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
