In specific use
Spring tension is 369.2N in the spring bracing piece of this embodiment, and decelerator mainly comprises round knot, spring bracing piece and thick compression spring, and two thin spring formula bracing pieces all are 60 jiaos with the safety rope, and the one end of thin spring and safety rope contact is equipped with the rubber pad (increase coefficient of friction effect), and the rubber pad end of two thin springs is on same water flat line, and 2 springs become bilateral symmetry and distribute.
The working principle is as follows:
the design demand is slowed down before falling to the ground 6m, so the rope at last 6m is equipped with circular knot every half a meter, and the diameter of circular knot is slightly greater than the distance of two thin spring rubber pad ends, and circular knot diameter is 0.8cm, and the distance of two thin spring rubber pad ends is 0.5 cm. When the escape person uses the device to escape and is 6m away from the ground, the round knot is contacted with the rubber pad ends of the two thin springs to generate friction (loss of the potential energy of the rope part), and simultaneously the spring type support rod is contracted to convert the kinetic energy into elastic potential energy to achieve the purpose of reducing the speed of the safety rope, so that the escape person can not damage the ground due to too high speed, the knot can relatively easily penetrate through the gap between the two thin springs due to the shape of the knot and the angle relationship of the two thin springs, not only can the length of the safety rope be completely utilized, but also has the speed reducing effect, because of the angle relationship of the two thin springs, two points at the end of the rubber pad generate larger extrusion force, the friction is further increased, the safety rope starts to reduce the speed and reaches the ground at the speed of about 1m/s, when the first escape person safely reaches the ground, the handle is loosened, and the safety rope is not subjected to the gravity of the, the handle is controlled by the circulating escape device, so that the safety rope starts to return, when the handle reaches the initial position, the speed of the handle can approach 0m/s in a very short time due to the action of the buffer device (namely, the coarse compression spring, the clamping plate and the handle), and then a subsequent person to be escaped can repeat the action of the previous escaper to escape.
