Fig. 7 is a force analysis diagram of the escape suspension system of the present invention, please refer to fig. 7, which illustrates the working principle of the present invention:
(1) lower slide
When a person sits on the escape hanger, the hanger 6 and the slideway 9 cannot provide enough friction force F to balance the gliding force F, and the person starts gliding at a constant speed. Assuming that the friction coefficient is μ, the inclination angle of the slide 9 is θ, the total gravity of the person and the hanger 6 is G, and the air resistance is 0, the slip force F is larger than the friction force F, that is, F ═ Gsin θ > F ═ μ Fn ═ μ Gcos θ.
(2) Braking device
According to the law of equilibrium levers: fn · L1 is G · L2, since L1 is fixed and gravity is also constant, the adjusting balance nut is equal to the adjusting power arm L2. When L2 changes, Fn changes accordingly, and the Fn-changing frictional force F changes, thereby changing the magnitude of the slip force F. When the slip force F changes, the slip speed of the person sitting on the hanger also changes, and the slip speed is controlled to be F/m
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
