Embodiment 1
[0040] Embodiment 1: A super-heavy glass door and window lifting system based on spring counterweight.
[0041] as attached Figure 1-15 A kind of super-heavy-duty glass door and window lifting system based on the spring counterweight shown in the drawing includes a movable glass leaf 9, a moving column arranged on both sides of the movable glass leaf 9 and driving the movable glass leaf 9 to move up and down, and evenly arranged on the movable glass leaf. The bottom of the fan 9 is connected to the power assist auxiliary column of the movable glass fan 9 lower frame through the transmission link 83.
[0042] The moving column includes a profile structure 1, a plurality of counterweight springs 2, a spring force collecting structure 3, a load-bearing transmission structure 4 and a motor transmission structure 5;
[0043] The right side of the profile structure 1 is provided side by side with a fixed glass fan installation groove 11 on the upper part and a movable glass fan in...
Embodiment 2
[0051] Embodiment 2: Test of the influence of the thickness of the scroll spring on the toughness and tension of the spring.
[0052] Use the controlled variable method to conduct 1,000 continuous uninterrupted rapid pull-up tests per hour on constant-force scroll springs made of 301 stainless steel with different thicknesses, so as to pull out the spring belt and automatically rewind the spring coil once. In the "rolling" operation, 100 scroll springs of each thickness level are randomly selected for testing, and the maximum number of rollings is recorded and the data range interval is marked. The test results are as follows:
[0053] serial number Thickness (mm) The maximum number of rolls Pull force (kg) Limit service life Estimated useful life 1 0.2 18000-20000 1.5 13.01369863 36 2 0.25 10000-15000 2 8.561643836 25.5 3 0.3 5000-8000 3.2 4.452054795 13.2 4 0.35 2500-3000 4.5 1.883561644 5.4 5 0.4 2000-2500 6.5 1...
