High-attitude intelligent life saving device

Abstract

The invention relates to a high-attitude intelligent life saving device. One end of the external surface of a double-layer permanent seat is provided with a rope pulley, the rope pulley is close to a floating rope-pressing pulley group, the upper end and the lower end of the floating rope-pressing pulley are respectively provided with a rope-guiding pulley group, and the middle cavity position of the double-layer permanent seat is provided with an accelerating gear transmission group. The invention has the technical effects that the intelligent and passive life saving device is realized by using mechanical-electrical integrated design, and the descending speed is controlled by using a singlechip microcomputer, so that the life saving device has better safety and stability, high speed and high comfort level; the safe reliability of the system is greatly improved, so that the intelligent slow-descending life saving device has strong overloading capacity; the use altitude range is large (in theory, as long as the rope can withstand the load, the life saving device can be used, and 1 km in altitude range can be reached under the conditions that the rope diameter is 3mm, the weight of people is 60kg and the allowable stress is 200mp.); the life saving device has small size and light weight and is convenient to install, store and carry; and no lubricating oil or grease leaks, and the life saving device does not contain toxic and corrosive materials and has low cost.

Description

Technical field [0001] The present invention involves a life -saving device, especially a high -altitude intelligent lifeser. Background technique [0002] With the continuous development of urbanization, there are more and more urban high -rise buildings. Due to various factors, the fire accidents in high -rise buildings are frequent, and the duration of the fire often ranges from several hours to tens of hours.Smoke, poisonous gas and other great harm to the safety of various types of people. At the same time, the risk of elevators (stop running at any time), and the long -term nature of stairs escape, which makes the outdoor escape a relatively fast and safe self -rescue method.At present, there are a variety of high -altitude slowdown in the market, such as the friction wheel -type slower device, relying on gear deceleration, and relying on elastic friction pieces to contact the friction wheel to consume most of the potential energy of the human body into thermal energy consu...

Problems solved by technology

At present, there are many kinds of high-altitude slow-descent escape devices on the market, such as friction-wheel-type slow-fall escape devices, which rely on gear deceleration and rely on elastic friction plates to contact the friction wheels to convert most of the potential energy of the human body into heat energy and consume it. Reduce the speed of the human body's descent to achieve the purpose of slow descent, but there are disadvantages such as high heat generation, easy loss of control, and low escape height of slow descent; another example is the electric descender, which relies on motor drive and gear deceleration to achieve slow descent, with stable speed, The escape floor is high and can be used multiple times. However, in the event of a fire, the power supply is usually not guaranteed. Once the power is cut off, it is more likely to be dangerous.

Others, such as hydraulic damping type descenders, are also difficult to control. Leakage caused by seal aging is prone to occur after being placed outdoors for a long time. Especially in winter in the north, hydraulic oil is prone to solidification, which may lead to safety hazards when used. ACCIDENT
