High-rise escape machine and automatic control method for escape

Abstract

The invention discloses a high-rise escape machine and an automatic control method for escape. The invention belongs to the technical field of fire fighting equipment, and is used for self-life saving for people in tall buildings in case of fire hazards. The high-rise escape machine comprises a centrifugal mechanism (7), a braking mechanism (35), a rope recycling mechanism (36), a microcomputer controller (11), a machine frame (1), a storage battery (26), an upper pulley (5), a lower pulley (6), a safety hook (3) and a rope (4). The automatic control method of the high-rise escape machine for escape monitors the speed in the escape process in real time by using a microcomputer, and automatically controls the height of the brake point and the magnitude of the brake power of the magnetic powder brake (10) according to the height of the building and the weight of the persons, thereby realizing quick and safe escape. The invention can be widely used for office buildings, classrooms, residences and other locations.

Description

technical field [0001] The invention relates to a high-rise escape machine and an automatic escape control method, which belong to the technical field of fire-fighting equipment and are used for self-rescue and escape when a fire occurs in a high-rise building. Background technique [0002] The high-rise escape machine (device) is a device used for people to escape and save themselves when a fire breaks out in a high-rise building. Through it, people can quickly escape from the fire scene and reach the ground safely and smoothly without any damage to the body. When a fire broke out in a high-rise building, the fire spread to the entire room in a very short period of time, burning houses, furniture, and decorations, and even causing trapped people to be injured or even killed. Elevators and corridors cannot pass during a fire. If firefighters cannot arrive in time, the fire will threaten people's lives. If corresponding escape devices are installed, people can save themselves...

AI Technical Summary

Problems solved by technology

[0003] At present, there have been some mature escape devices at home and abroad: (1) portable escape rope, when in use, one end section of the rope is fixed on the supporting object, and the other end is hung on the safety belt, and the personnel hold the rope and slide slowly, This kind of escape device is very convenient to use, but it is difficult to adjust the speed. The success of escape depends on the skill of using the escape rope. If it is used improperly, it will cause serious injury to people. (2) Fire escape ladders mainly include ladders permanently fixed on the outer wall and rope ladders (or folding ladders) temporarily lowered from the window sill. There are disadvantages such as low applicable height, fire will be affected during the escape process, and slow escape speed; (3) various descending devices, the principle of which is to increase the friction between the rope and the device or artificially create lift through various means , reduce the speed of rope descent, and the personnel slowly descend to the ground through ropes or hanging baskets. The device is safe and reliable, but the device is large in size, high in price and cost, and difficult to popularize and apply; (4) centrifugal high-rise escape device, such as the patent "Safe Escape from High Building Device" (Patent No.: ZL01255973.3), this high-rise escape device cleverly converts the downward gravity of the human body into a rotational speed, which in turn generates rotational speed, centrifugal force, positive pressure, sliding friction, and frictional resistance torque, reducing the speed of people falling. Acceleration eventually makes people fall at a constant speed and land safely. The escape device has a simple structure and low cost, but it cannot adjust the speed of people’s descent. The weight of people is different, and the speed of landing is also different. The greater the falling weight, the greater the speed of landing

[0004] The above four escape devices all have certain applicable occasions, but for buildings ten to one hundred meters high, there are deficiencies such as difficulty in adjusting the escape speed, poor rapid safety, high operating technical requirements, and poor rapid recyclability, which cannot meet the needs of rapid safety, simple structure, Ease of use and low cost for escape requirements
