Embodiment Construction
[0012] The present invention is described in further detail by the following examples.
[0013] see figure 1 — Figure 4 As shown, a high-rise escape device consists of a box body 12, an escape rope 8, a main pulley 2 arranged in sequence from top to bottom in the inner cavity of the box body 12, a pair of guide pulleys, 2-5 sets of pulley pairs, and a first guide pulley. Pulley 4 and brake mechanism form. The axis center of the main pulley 2 and the axis center of the first guide pulley are located in the box body 12 and on the y coordinate axis passing through its center point 0, and the second and third guide pulleys 3, 3, The axis of 11 is symmetrical and equidistant from the y-coordinate axis. The present embodiment adopts two sets of pulleys with the same structure, i.e. the first pulley 10 and the second pulley 9. Taking the second pulley 9 as an example, the structure is as follows: the pulley 9 is composed of two pulleys positioned on the upper horizontal plane 16 ...

The invention discloses an escape device for high-rise buildings, which is convenient to operate and control, can control the fall velocity of an escaper, is safe and reliable and suitable for ordinary people. The escape device is characterized in that a main pulley, a guide pulley pair, at least two pulley blocks and a first guide pulley are arranged in sequence from top to bottom in the inner cavity of a box body; the axle centers of the main pulley and the first guide pulley are positioned on a y-coordinate axis which is located in the box body and passes through the center point O of the box body; each pulley block comprises two pulleys positioned on an upper horizontal plane and two pulleys positioned on a lower horizontal plane, which are symmetrical and have equal distance with the y-axis respectively; the distance between the axle centers of the two pulleys on the upper horizontal plane is more than that of the two pulleys on the lower horizontal plane; an escape rope enters from one side of the first guide pulley, passes by the pulleys in the box body and the main pulley in a zigzag shape and goes out from the other side of the first guide pulley; safety hooks are arranged at the two ends of the escape rope and at the top of the box body respectively; and a brake mechanism is arranged between the surface of the main pulley and the box body.
Description
technical field [0001] The invention relates to the technical field of escape appliances, in particular to a high-rise escape appliance. Background technique [0002] An existing life-saving descending device is mainly composed of a set of acceleration gears, an escape rope, and a movable film. One end of the escape rope is connected to the input shaft of the acceleration gear set. The escaper holds the other end of the escape rope, and the acceleration gear set The output shaft is equipped with a movable film and is in contact with the wall of the device. The friction generated by this contact is only about ten kilograms. Only a certain speed of descent will produce friction, and the greater the speed of descent, the greater the friction. This kind of life-saving descending device has a fast deceleration, which can reach about 0.5 meters per second, and there is no speed regulating and braking device, so it is difficult for people without professional training to control i...
